Introduction to the deformation joint device, introduction to the building deformation joint device

At present, the scale of large-scale public buildings and combined industrial plants has grown from tens of thousands of square meters to hundreds of thousands of square meters. In order to prevent the damage caused to the building due to the uneven settlement and temperature deformation of the building, the deformation joints should be set up in accordance with the relevant specifications in the structural design, and the architectural design should also be constructed for the deformation joints. The traditional practice is to use galvanized iron sheet, steel plate or aluminum plate on-site processing and production, the structure is simple and rough, not only not beautiful and short life, backward materials and processing technology can no longer meet the needs of the development of the modernization of the construction industry.

Building deformation joints, I believe everyone has seen this. From large to small, horizontal to vertical, there are all kinds of things. This crack is due to the influence of external forces on the building, and the wall is damaged, which is a very big threat to the beauty of the building and the personal safety of the occupants.

But this kind of crack can't be repaired, and even if it is repaired, it can't be repaired to the previous level, so how can this problem be solved?

Building deformation joint device, as the name suggests, it is a device specially used to solve the deformation and cracking of buildings, and it is also a kind of building accessories to decorate building gaps. Briefly talk about itConstruct the type of bar

The first type, metal card lock type: suitable for building deformation with a seam width of 5 to 45 cm. It consists of a base, a side cover and a central sliding delay cover. Installation is simple and convenient.

The second type, metal cover type: suitable for building deformation with a seam width of 5 to 45 cm. It is composed of three parts: the base, the center plate and the slide bar.

It is characterized by the fact that the base of the two deformation joint devices is connected with a slide bar, so that the cover plate is always in the center of the joint. Improved safety performance.

The third type, double-row mosaic type: it is also suitable for building deformation gaps with a seam width of 5 to 45 cm, but this has a certain aesthetic improvement from the above, because this type of building deformation device has a groove type, then we can embed the same decorative materials as the surrounding materials in the grooves. It is usually used in some high-end places with high environmental requirements.

The fourth type, single-row embedded flat type: it is composed of two parts: the base and the rubber strip, which is suitable for relatively large gaps. It is characterized by a good concealment type after installation, and can be integrated with the surrounding materials.

Let's take a look at how it works.

When installing, we must first chisel the construction position into the shape we need, knock out the excess parts, and make up for the defects. After doing this, we connected the deformation joint device to the main structure of the building by means of expansion screws. When choosing a location, it is important to take care to take the midpoint of the deformation joint as the base point and stake it out to both sides.

After the installation of the base of the building deformation joint device, we need to seal the gap between the base and the wall with a special coating to prevent water leakage. Finally, we need to make sure that the installation is level with the wall or floor.

Summary:The above is all the content of the building deformation joint device introduced to you, in general, it is also a product that came into being, and it also ensures our personal safety to a certain extent. Hope it helps.

Combined with the construction of deformation joints in China's construction industry, at this stage, what are the regulations on the construction process of deformation joints in China's construction industry? What is the basic situation? The following is a basic introduction to the deformation joint process of Zhongda Consulting's construction terminology:

Deformation joint is a general term for expansion joints, cracks, settlement joints and shockproof joints. Buildings are often deformed under the action of external factors, leading to cracking and even destruction. A deformation joint is a construction joint that is reserved for this situation.

In order to help the personnel of construction enterprises to further understand the construction process of deformation joints, combined with the content of the construction process of deformation joints, the basic construction situation is as follows:

1. Slot reservation and processing.

2. Hold the straightness of the whole seam.

3. Clean the debris and garbage in the seam.

2. Stick the waterstop.

1. Clean the installation base.

2. The elastic line determines the fitting position of the waterstop, and the width of the waterstop and the installation base surface.

4. The two waterstops are connected by lap glue, and the joint length is about 10cm. Brush the base glue on the joint part of the waterstop, and when it dries to the point that it is not sticky, it is laminated, pressed, and compacted.

5. Under normal circumstances, when encountering the pillar part, the waterstop should be pasted continuously. The waterstop at the end of the two ends of the seam is erected and fitted 15 20cm, and fixed with metal pressing.

6. When there is a lot of indoor water, the two ends of the waterstop should be led through the wall crack to the waterstop or the inner leather strip of the outer wall joint. Or install a drainage device on the waterstop, and the drainage device can be used with a general downpipe.

7. The waterstop can be broken with a utility knife.

2. Install aluminum alloy base and waterproof adhesive strip.

1. Put on the aluminum alloy base, and mark the position of the hole on the base with red paint on the installation base.

2. Drill holes with an electric hammer at the marked position and install a 6mm plastic expansion tube.

3. Put on the aluminum alloy base and screw the M4 garden head self-tapping screw.

4. Install the water-stopping rubber strip on the aluminum alloy base. Shape shown when finished.

5. The aluminum alloy base can be sawed off by a hacksaw or sawed off with an aluminum alloy cutting machine.

3. Install the slide bar and cover plate.

1. Put on the cover plate and mark the installation position of the slide bar on the aluminum alloy base.

2. Fix the slide rod to the part to be installed with tape paper.

3. Put on the cover plate and screw the slide rod. Shape shown when finished. (Same as the product picture).

4. Align both sides of the cover plate joint.

5. The aluminum alloy cover plate can be sawed off with a hacksaw, and the aluminum alloy file is filed. The stainless steel cover plate can be cut and smoothed by an angle grinder with a 1mm or 2mm grinding wheel cutting disc.

The categories of deformation joints may be familiar to many people, but they must not be detailed and cannot be mentioned one by one. Zhongda Consulting will briefly talk to you about the category of deformation joint device.

Deformation joint device is a set of practicality and decoration in one, by the specialized factory production of industrialized stereotyped products, it has the characteristics of exquisite workmanship, beautiful appearance, product standardization, long service life, etc., is the ideal building accessories to cover the deformation joint of the building.

According to the use of the building, it is divided into: floor and ground deformation joints, exterior wall deformation joints, interior wall deformation joints, ceiling deformation joints, roof deformation joints, and glass curtain wall deformation joints.

According to the characteristics of the use form of deformation joints, it can be divided into: plane type deformation joints and corner type deformation joints.

According to the structural characteristics of the deformation joint device, it can be divided into: metal cover plate type; Metal card lock type; Single-row embedded flat type; The double-column embedded flat type is introduced as follows:

1) Metal cover plate type: It is composed of aluminum alloy base, aluminum alloy (or stainless steel or copper) plate cover plate, and central control slide bar. Applicable seam width 75 450mm.

The characteristics of the metal cover plate type are that the central control central control slide rod is used between the cover plate and the base fixed on both sides of the deformation joint, and the slide rod is placed obliquely at an angle of 45 ° during installation, when the base is displaced, the metal cover plate is always maintained in the center position of the joint, and the thickness of the cover plate can be increased when it is used for the floor, and the bearing capacity can be improved. The general load-bearing type load is the forklift passing).

The metal cover plate shaped roof deformation joint device is also "l', shaped,"T-shaped, "+-shaped and parapet wall, a variety of yin and yang corners are designed with special accessories.

2) Metal card lock type: It is composed of aluminum alloy base, aluminum alloy side cover plate, and aluminum alloy center sliding cover plate. Applicable seam width 50 450mm. The central sliding cover plate is sandwiched between the side cover plate and the aluminum alloy base, which has the characteristics of neat appearance and easy installation.

3) Single-row embedded flat type: composed of aluminum alloy base and rubber strip. The applicable seam width is 25 100mm. It has the characteristics of simple structure, good waterproof performance, and the combination of rubber strip and decorative layer is tight and smooth. Can be used on outdoor platforms.

4) Double-row embedded flat type: It is composed of an aluminum alloy base for the rest of the base, an aluminum alloy center plate, a central control slide bar and a rubber strip, and the applicable seam width is 75 450mm. The double-row embedded flat aluminum alloy center plate is a profile with grooves, which can be embedded with decorative materials such as stone, floor tiles, carpets, etc., which is consistent with the overall indoor floor materials, and is especially suitable for floors with high cleanliness requirements.

The structural requirements of exterior wall deformation joints are thermal insulation, waterproofing and beautiful façade. According to the size of the seam width, the seam should generally be filled with elastic materials with waterproof, thermal insulation and anti-corrosion. The outside of the deformation joint is usually covered with galvanized iron sheet and aluminum plate with good weather resistance.

However, attention should be paid to the structural treatment of the metal cover, which should be adapted to the deformation needs of telescopic, settlement or shaking and swinging.

The structure of the deformation joint of the interior wall should mainly consider the decoration coordination of the indoor environment, and some should also consider sound insulation and fire prevention. Generally, it is covered with wooden strips with a certain decorative effect, and metal plates can also be used to cover the seams, but it is necessary to pay attention to the ability to adapt to different deformation requirements.

It is recommended to ask a professional, or there is a discussion on this issue on the Fantong forum.

3. All of them, if the waterstop, fire barrier and thermal insulation belt are configured in the building deformation joint device, the deformation joint device can also meet the design requirements of waterproof, fire prevention and heat preservation. The waterstop is made of thick LThe 2mm EPDM sheet can be used in a natural environment of sun, humidity and cold for a long time.

The fireproof belt is a special accessory composed of aluminum silicate refractory fiber felt sandwiched between two layers of stainless steel lining, and the two sides of the fireproof belt are fixed with the main structure of the building. The fire retardant tape can meet the requirements of different fire resistance limits of 1-4h.
