The quality of plastic steel windows is unqualified, and the installation quality inspection of plas

Don't sign an agreement to ask them to replace it again, you can go to the Quality Supervision Department of the Construction Bureau, and the unqualified products must be replaced. But you most leave evidence and written materials to reflect on the construction.

The plastic steel window is guaranteed for one year.

How to accept the unqualified plastic steel window quality inspection bureau.

You can go to the Quality Supervision Bureau of Min'an Street to ask.

Doors and windows on-site quality inspection regulations them.

Have the plastic steel windows in your community been accepted?

How can such a quality plastic steel window door be accepted?

Now the country attaches great importance to air tightness and thermal insulation performance.

Go to the Quality Inspection Bureau and ask.

If it passes the inspection.

Then the Quality Inspection Bureau will come forward.

To put it mildly, this problem is now too common, super common, almost all over the country is the case, serious deformation, drought, some of the main frame breaks, you said that there are only two possibilities for this situation, one is the problem of the material itself, the other is man-made (such as hitting the window, squeezing, etc.) or climate (such as wind) problems.

It's too late to say that.

Don't think it's too worthless to make up 40, and the developer doesn't want this problem to occur, the 40 yuan is not made up, nor is it used by you to repair doors and windows, which can be said to be a "hush money", hehe.

I didn't speak for those "black-hearted" developers, but this is the reality, and if you really go to court to complain in this situation, I personally think it won't have any effect, and it's not interesting to think about it.

The power of the masses is great, the only thing is to make them lose more money.

If you want to open your heart, you don't say that some have signed an agreement, whether they want to open it or not, at least now they have such a headache compared to you.

This is to find **, but to be reasonable, legal, write a written complaint, just wait for the solution of **, this is a people's livelihood problem, this is your words on the first floor, hey 、、、

How to check the installation quality of plastic steel doors and windows?

Take a look at the surface of the window: the window frame should be clean, smooth, smooth, no scratches and bruises on the large surface, and no open welding fracture of the profile.

Second, look at the hardware: the hardware should be complete, the position is correct, the installation is firm, the use is flexible, and the respective functions can be achieved.

Third, look at the glass sealing strip: the contact between the sealing strip and the glass and the glass notch should be smooth, and the edge should not be curled or de-grooved.

Fourth, look at the sealing quality: when the doors and windows are half-closed, there is no obvious gap between the sash and the frame, and the sealing strip on the sealing surface should be in a compressed state.

Five look at the glass: the glass should be flat, installed firmly, there should be no loosening, the single-layer glass should not be in direct contact with the profile, the inner and outer surfaces of the double-layer glass should be clean, there should be no dust and water vapor in the glass interlayer, and the partition should not be cocked.

Sixth, look at the bead: the strip with the sealing strip must be fully attached to the glass, there should be no obvious gap between the bead and the profile, and the joint gap should be less than or equal to 1 mm. Push-pull.

Seven look at the puzzle material: the puzzle material should be tightly connected with the window frame, and at the same time sealed with caulking paste, shall not be disturbed, the screw spacing should be less than or equal to 600 mm, and both ends of the branch code lining reinforced steel should be fixed firmly with the hole. Quietly matched.

Eight look at the switch parts: casement, sliding or rotating windows should be closed tightly.

9. Look at the connection between the frame and the wall: the window frame should be horizontal and vertical, the height is consistent, the spacing of the fixing piece should be less than or equal to 600 mm, the frame and the wall should be firmly connected, the gap should be filled with elastic opening finger material, the surface seam paste is sealed, and there are no cracks.

There is a factory date, number, user name, project name, product name, specification, quantity, batch number, implementation standards and test results, etc., which is the certificate.

A plastic steel door

(1) Plastic steel doors and windows were first developed by West Germany at the end of the fifties of the last century, and began to be produced in 1959. With the worldwide energy crisis in 1972, plastic steel doors and windows with better energy-saving effect in the early seventies have been widely used.

(2) It also promotes the improvement of profile production technologyThe performance is improving day by day, from the original single-cavity profile to three-cavity and four-cavity profile, which has also driven the development of plastic steel doors and windows in Europe and even Asia. According to incomplete statistics, the use of plastic steel doors and windows in Germany has accounted for 52% of the door and window market.

Second, the development history of plastic steel doors and windows

(1) Plastic steel doors and windows are made of polyvinyl chloride (PVC) resin as the main raw materialAdd a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extrude the molded materials, and then make door and window frames and sashes by cutting, welding or screwing, and install sealing strips, wool tops, hardware, etc.

(2) China's plastic steel doors and windows started lateThe calcium-plastic doors and windows produced in the seventies are not of good quality and have been basically eliminated. The production of real plastic doors and windows began in 1983 by the introduction of equipment, when the technology was not very advanced, all using single or two-cavity structural profiles, with the improvement of the industry in 91 years, a number of extrusion equipment, molds, profiles, assembly equipment and other manufacturers have emerged in China.

Consumers pay too much attention to the profile brand when purchasing plastic steel doors and windows, in fact, the factors that affect the quality are not only the brand of the profile, the configuration is more important, the qualified finished plastic steel doors and windows are composed of the main material profile, equipped with steel lining, sealing strips, hardware, insulating glass technology, as well as rigorous plastic steel doors and windows production process! Harbin innovative plastic steel doors and windows distribution department publicity.

1. The steel lining is the skeleton of the profile, its function is to prevent the deformation of the profile, enhance the wind pressure resistance of the finished window, the wall thickness of the steel lining can not be less than, fasten with screws and the profile, fasten the distance between the steel lining and the screws of the profile is not more than 350mm, and the screws fastening each profile shall not be less than 3, and the distance between the two ends shall not be more than 100mm.

Now the air permeability phenomenon of insulating glass of Harbin plastic steel windows is also very common, the reason is that the production process does not meet the standard, the standard process is the aluminum tube double-channel sealing (butyl rubber double-channel sealing process), and now most of them are heat sealing process, the air permeability is very high.

3. Due to the low quality of the hardware, the fan is not closed strictly, the inferior hardware has a short service life and is easy to damage, especially the lock point is more likely to be damaged, resulting in the fan can not be closed well, and the brand's hardware is of high quality, the damage rate is very low, and the quality of domestic brands such as: Guoqiang and Chunguang are very good.

4. The elasticity of the inferior rubber strip is not good, the service life is short, especially in winter, the rubber strip is hard like a steel bar, and it loses its elasticity, resulting in the opening fan can not be crimped tightly, the fan should use EPDM strip, which has good elasticity, cold resistance, and long service life, and the method of identifying EPDM strip is very simple.

5. To purchase Harbin plastic steel doors and windows, you must understand: steel lining wall thickness, insulating glass technology, hardware brand, rubber strip material, production standards, only by looking more and asking more can you ensure the quality of the plastic steel windows you purchase!

1. The color of plastic steel is not as white as possible, it should be white and clear, and the feel is excellent, which is essentially different from calcium plastic.

2. Plastic steel is composed of rigid polyvinyl chloride hybrid resin (PVC-U) profiles and metal reinforced aggregates. PVC-U material is tough and elastic. The high-quality plastic steel lining metal is treated with anti-rust treatment and has a certain thickness.

3. High-quality plastic steel door and window accessories are printed with brands and names, and the color is smooth and clean.

4. The precision of processing and the fullness and uniformity of welding are a major sign of the quality of plastic steel.

5. High-quality plastic steel doors and windows should have quality assurance certificates and production licenses.

6. Plastic steel doors and windows can be prepared with monolithic glass, vacuum glass and laminated glass.

Hello dear, happy to answer your <>

Answer: The reason why the upper part of the plastic steel window is not closed tightly is that the door and window frame or fan is deformed, and the sealing strip is loose or falling off. If there is bending deformation, it is easy to find, and this type of material should be resolutely not used, if the plastic steel profile is not bent and deformed, the closure is not tight, it should have nothing to do with the plastic steel profile.

After ruling out one factor, we can look for reasons in other areas. Second, the seal falls off, if the seal hardens and falls off, it can cause the closure to be not tight. You should buy high-quality sealing strips with good elasticity on the market.

If it is a profile, it is best to come with a co-extrusion sealing strip. Generally, this kind of sealing strip has high anti-aging strength, good elasticity, and is not easy to shrink or harden. However, this kind of sealing strip sometimes has a little less dimensional accuracy, but due to its good elasticity, it generally does not cause loose closure due to size and accuracy.

3. Hardware accessories reason: Hinges, lock points, lock blocks, clutches, and gaskets are the key to ensure that doors and windows are closed tightly. First of all, you must buy the hardware of a regular enterprise.

Hardware must meet national standards. The dimensional error of the hardware must be accurate within the specified range. The hardware material must meet the standards of rigidity and strength, otherwise the difference will be a thousand miles.

This is the main reason for the poor closure of doors and windows, especially in the northeast region, where large sections, large cavities, thick-walled profiles, and steel linings are also very heavy. In this way, the hardware is required to have a certain rigidity and strength. Preferably high-quality hinges with lock points.

In this way, we can ensure that the doors and windows are not opened, not deformed, and closed tightly. Fourth, installation and production: plastic steel profile cutting should be accurate, window sash accuracy should be accurate.

Before the door and window sash into the frame, check the diagonal and flatness deviation. After entering the frame, use a steel plate ruler and feeler gauge to check the lap width of the frame fan and the gap around it until it meets the requirements. Install the hardware correctly, and replace it in time if it is damaged.

The choice of gasket must be fine, often poor millimeters may cause the closure is not tight. The locking point thickness and the amount of adjustment ensure a tight close. The flatness of the sash frame is also the key to whether the closure is tight.

Wearing steel lining and welding, the rear frame and the fan should be stacked to prevent deformation. The installation should be according to the process, and the window frame and window opening should be drawn out of the center line. When the window frame is in the hole, the center line should be aligned.

The corner of the frame is temporarily fixed, and the verticality, horizontality and straight angle of the window frame are carefully adjusted, and the error should be within the allowable deviation range. 5. Finished product protection: It is very important to do a good job in the protection of finished products, and the handling and stacking should be smooth, not affected by external forces, and heavy objects should not be hung, resulting in deformation of doors and windows.

When using, it should be opened and closed lightly, which can also protect the hardware and prolong its life for staring and buriding.

1. Affect daily normal use.

Inferior door and window hardware accessories must not meet the standard production, and there will be rust and paint stripping after a long time, and the key connecting parts will fall off, resulting in doors and windows can not be opened normally, and there is also a certain probability of causing the window sash to fall and cause unimaginable safety hazards, so inferior doors and windows will inevitably suffer from hardware accessories.

2. Hidden dangers are greater than safety.

The frequent news of children falling from the building or falling from high-altitude window sashes mainly occurs in the quality of unqualified doors and windows, so you must be careful when choosing doors and windows, don't always look at the price to choose the product, to think about whether the quality and functionality of the product meet this price, only if the early stage is done, the later stage will be less troublesome.

3. Doors and windows are not energy-saving.

Doors and windows are the weakest link in the building, so the loss of energy accounts for 45-50%, this is a qualified door and window product data, it is conceivable that if an inferior door and window product loss is greater than this value, so don't expect inferior doors and windows to resist the cold weather for you, and at the same time will make your refrigeration equipment more power-consuming.

If substandard doors and windows are installed in the home. First of all, the insulation is not good, because the quality of the doors and windows is not up to standard, and there will be air leakage. The second is that such doors and windows are relatively noisy. There is a sound when the doors and windows are opened.

My second brother in this door and window caused by this impact is serious machine, this unqualified is not in place to install, for the future use will shorten its life, affect the whole beauty.

Unqualified doors and windows, not only the material used is not environmentally friendly, but also easy to damage in the face of strong wind and rain

Hello, the performance of good doors and windows still has a greater impact on the home. If substandard doors and windows are installed in the home. First of all, the insulation is not good, because the quality of the doors and windows is not up to standard, and there will be air leakage.

You won't enjoy the feeling of being warm in winter and cool in summer. Secondly, such doors and windows are relatively noisy, and if they are close to the side of the road or the square, they are very noisy. And when you open the doors and windows, it makes a noise.

First, it is firm, and the four corners of plastic steel door and window frames and fans are usually welded, and the national standard requires that the average angular strength should reach more than 3000N. For example, you need to have formal welding equipment to be able to ***, and the small processing shops on the side of the road are basically not guaranteed. In addition, the connectors and fasteners should be firm, because the main material of the plastic window is PVC, and the cross-sectional wall thickness is usually around the right, which can not withstand hardware such as casement window hinges.

They need to be supported by a steel lining of sufficient thickness inside, so before purchasing, it is necessary to carefully observe whether the manufacturer is short of a small amount or the possibility of cutting corners, and it is not easy to check the thickness of the internal steel lining after the doors and windows are made into finished products.

The second is accuracy, which is mainly reflected in the accuracy of the size. It includes the size of the opening when it is actually measured and the size of the sash and frame after installation, and the size of the actual size is not accurate and often affects the opening of doors and windows, the sealing of doors and windows, etc.

Ordinary door and window frames and sash lap are generally 8-10mm, if the size is too small (such as 4-5mm), its sealing performance is questionable.

The third is flatness, which includes the welding angle can not be high and low dislocation, and the two windows can not be uneven. This is mainly reflected in the appearance, and it is also an important item that brings beauty to our vision. And there are also specific embodiments in the national standard, such as:

The height difference of the weld angle should be within the range, etc. It doesn't matter if you don't know the national standard in this case, but you have to see his sample window, and then require its appearance quality to reach the sample window, and the quality of the sample window displayed by the general business is still OK.

Fourth, the sealing performance, the size mentioned above will affect the seal, if the manufacturer buys unqualified accessories, it will also affect the seal. For example, the inferior rubber strips used by some manufacturers begin to shrink within half a year, resulting in a large gap between the glass and the fan, and the rain and air can easily enter the room.
