What material is used for waterproof steel plate, and where is the waterproof steel plate suitable f

The waterstop is made of Q235 steel, and there is also copper.

The flexibility and waterproof performance of the copper waterproof steel plate are better, and the ** is also relatively high.

Steel plate waterstop.

It is a commonly used material in engineering, including steel plate and copper plate.

alloy steel plates, etc., are mainly used for reinforced concrete structures.

dams and other large-scale projects.

The use of steel plate waterstop can change the infiltration path of water and extend the infiltration route of water. In a construction environment where leakage may contain corrosive components, sheet metal waterstops can play a certain role in corrosion. In the protection project, the use of metal plate waterstop can ensure the protection effect of the project.

Sheet metal waterstops are also commonly used in projects with high impermeability requirements and small areas, such as casting pits in smelters, electric furnace foundation pits, etc. The section of the steel plate rubber waterstop adopts a non-equal thickness structure, which is divided into a strong area and a waterproof area, so that each part is stressed evenly and reasonably. The long-term wall of the expansion hole is flat, and the contact surface of the plate mold clamping is large during construction, and it is not easy to displace; The steel plate is connected with the steel bar with additional installation holes, and it is fixed firmly and is not easy to displace.

Galvanized steel. Good adhesion to concrete, so that the waterproof performance is better.

Water-stopping steel plates can be mainly divided into: ordinary steel plate waterstops, galvanized steel plate waterstops, stainless steel plate waterstops, specifications *5 and other specifications. It can be customized according to user requirements.

Usually in order to facilitate the operation and processing into 2m per section, attention should be paid to lap during construction, the weld surface should be welded well, the corner should be treated reasonably, and the water stop of the steel plate should be fixed firmly with the steel bar of the wall (or plate). The steel plate should be straight and not twisted. If the steel plate waterstop is used in the construction of horizontal joints, it should be cautious.

The water-stopping steel plate is naturally a steel plate, Q235 steel plate, 2-3mm thickness, 300mm width, 30mm up and down and 30mm folded into a 60-degree angle.

Most of the Q235 steel can be added with a galvanized layer of stainless steel, copper and other materials, of course, it is much higher.

Waterproof steel plate can be mainly divided into: ordinary waterproof steel plate, galvanized steel plate, corrosion-resistant waterproof steel plate Embedded waterproof steel plate The material is mostly black steel and Q235 steel.

The waterproof steel plate is suitable for all construction joints of walls with waterproof requirements, and is widely used. The main cases are as follows:

1. Post-pouring belt for construction projects.

2. The construction joint of the formwork pouring of the tall building.

3. Construction joints for building foundation and wall to be poured separately.

4. The construction joint of the bottom plate of the basement.

5. The construction joints at the joints of the sectional construction of the large area of the building.

These five situations are the most common, and others may also have some small places that require waterproof steel plates.

The waterproof steel plate belt is mainly used for reinforced concrete waterproof steel plate structure, dam and other large-scale projects. Such as: tunnels, subways, embankments, culverts, construction joints in water conservancy and hydropower projects, high-rise building basements, underground parking lots and other major engineering construction joints.

Steel plate waterstops play an important role in infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy, subway and other projects.

The main application scope of waterproof steel plate: tunnels, subways, embankments, culverts, construction joints in water conservancy and hydropower projects, basements of high-rise buildings, underground parking lots, etc.

Sheet steel waterstops are often used in box-shaped foundations, or in basements. Because the exterior walls and floors are generally poured with concrete alone, there will generally be a gap in the joint position, and if the position of this gap will be lower than the groundwater level, it is easy to leak, so it is necessary to install steel plates.

Construction joints for the construction of the foundation and the walls of the building are poured separately.

A construction joint for a particularly tall building wall that is poured in two formwork.

The post-pouring belt part of the construction project.

Basement floor construction joints. In order to prevent the underground pressure water from seeping upwards along the gap of the bottom plate of the two pourings, a water-stopping steel plate should be set on this construction joint, and the water facing downward.

Definition of water-stopping steel plate: the horizontal components and vertical components of the basement of the building cannot be poured at one time, and the horizontal construction joints are generally left at the position of 300mm on the foundation bottom plate, and the water-stopping steel plates are placed at the position of the construction joints. The waterproof steel plate is generally 400mm wide, and half of the new and old concrete are embedded.

The water-stopping steel plate is also known as the steel plate waterstop.

The water-stopping steel plate generally uses the cold-rolled plate as the base metal, because the thickness of the cold-rolled plate is uniform.

Cold-rolled steel plate. The thickness range of cold-rolled steel plate is:

The commonly used specifications are: 200*2 200*3 300*2 300*3 350*2 350*3 330*5 400*4

Common specification table for waterproof steel plate.

The common material is Q235 ordinary steel plate copper.

Steel plate alloy steel.

galvanized steel, etc. In order to facilitate transportation, the general waterproof steel plate is processed into 3m long.

According to the different production processes and construction parts, the waterproof steel plate is divided into ordinary waterproof steel plate, L-type waterproof steel plate, W-type waterproof steel plate, etc.

Since its establishment in 1985, the factory is a professional manufacturer of building accessories, the factory has advanced waterproof steel plate production equipment, strong technical force and many years of work experience.

Pay attention to the waterproof steel plate Gude Baijia.

The waterproof steel plate is a steel plate with a width of 300 or 400 that is arranged at the position of the construction joint when the horizontal components and vertical components of the basement of the building cannot be poured at one time, and the two ends of one side of the steel plate are cocked, which can play a good waterproof role.

Generally, the steel plate waterstop is made of cold-rolled plate as the base metal, because the thickness of the cold plate can be uniform, and the thickness of the hot plate is generally not uniform, the thickness is generally 2 mm or 3 mm, and the length is generally processed into 3 meters long or 6 meters long, which is generally three meters good for transportation.

The waterproof steel plate is a galvanized steel plate, which is mainly used in engineering projects with large water flow impact, such as dams, sewage treatment plants and other projects. The surface of the product is relatively smooth and there is no oil stain. When installing, it should be noted that the welding needs to be firm in order to withstand the impact of large water flow.

The underground structure and horizontal structure of the building generally cannot be poured at one time, so there will be a designed construction joint at the junction of the two sections, and if this position is lower than the groundwater level, it is easy to produce water seepage and leakage. In this way, it is necessary to do waterproof treatment in this seam, and generally use waterproof steel plate or rubber waterstop. Both have their own advantages, waterproof steel plate with its material advantages, not easy to deform, easy to build, but its steel material determines that it is easy to rust, especially after water, under hot and humid conditions.

Although the rubber waterstop will not have the phenomenon of rusting, and the life can be as long as 30-50 years, but its texture is relatively soft, because it is also embedded in the concrete during construction, it is easy to produce deformation, once the displacement occurs, it will greatly reduce the waterproof effect, and there will be many sharp objects such as stones or steel bars inside the concrete, it is easy to puncture the waterstop, and the construction needs to pay special attention. In the near future, we will introduce the waterproof steel plate in detail.

The definition of water steel plate is that when the horizontal component and the vertical component of the basement of the building cannot be poured at one time, the steel plate with a width of 300 or 400 that is arranged at the position of the construction joint, the steel plate is cocked at both ends on one side, can play a good waterproof role, and its principle of action is: the joint position of the new and old concrete is the weakest link of waterproofing, after the waterproof steel plate is installed there, when the water penetrates inward along the construction joint, the waterproof steel plate is blocked by the route of its penetration and can no longer continue, so as to achieve the waterproof effect, Even in the case of large seepage volumes, the seepage path can be greatly extended.

Attention should be paid to the following points in the installation of the waterproof steel plate: the first thing to determine is the orientation of the "opening" of the waterproof steel plate, and ensure that its opening is facing the "water surface" of the building. Secondly, try to ensure that the center line of the waterproof steel plate coincides with the construction joint of the wall, so as to achieve the best waterproof effect.

Finally, the part of the waterproof steel plate that needs to be lap welded should ensure that the lap length is not less than 500mm to ensure that the lap is firm.

Waterproof steel plate is a kind of building accessories, mainly used in: basements, underground structures, dams, reservoirs, swimming pools, roofs and other building materials, expansion joints.

By changing the infiltration path of groundwater, it plays the role of water stop and waterproofing.

Definition of waterproof steel plate:

Water-stopping steel plate, also known as steel plate waterstop, is generally Q175 Q195 Q235 three materials, common three centimeters or five centimeters of folding, there are also some customized U-shaped V-shaped steel and other special-shaped waterproof steel plates.

Reasons for setting up water-stop steel plates:

In the box foundation or basement, the concrete of the bottom plate and the exterior wall slab is poured separately, and the next time the wall slab concrete is poured again, there is a construction cold joint, and when the position of this joint is below the groundwater level, it is easy to produce water seepage. In this way, it is necessary to carry out technical treatment on this seam, and there are many ways to deal with it, among which the more common method is to set up a waterproof steel plate.

The water-stopping principle of the water-stopping steel plate:

The horizontal components and vertical components of the basement of the building can not be poured at one time, and the horizontal construction joint is generally used to return to the 300mm position on the foundation bottom plate, and the water-stopping steel plate is located at the construction joint, and the water-stopping steel plate is generally 400mm wide, and half is embedded in the old and new concrete. The joint position of the new and old concrete becomes the construction position, which belongs to the weak link of waterproof concrete waterproofing, after increasing the waterproof steel plate, the water can not continue to penetrate after encountering the waterproof steel plate when infiltrating along the gap of the new and old concrete stubble position, the waterproof steel plate plays the role of cutting off the water infiltration path, and penetrates along the gap between the waterproof steel plate and the concrete in time, and the waterproof steel plate has a certain width, and also extends the penetration path of water, and can also play the role of waterproofing.

Summary. It is a commonly used material in engineering, mainly including steel plates, alloy steel plates and other materials, which are used in the construction of concrete, dams and other large-scale projects.

It is a commonly used material in engineering, mainly including steel plates, alloy steel plates and other materials, which are used in the construction of concrete, dams and other large-scale projects.

The medium is oil, and what material is used for the waterstop.

In case of oil corrosive medium, it is advisable to use butadiene rubber.

The waterproof steel plate is made of Q235 steel material, because it is always difficult to avoid the appearance of building gaps when building, once it is in the humid cherry finger environment, it is very easy to cause problems such as water seepage inside the building, and such problems are difficult to solve in the later stage of building construction, so fillers are generally used to fill the gaps in the construction process.

The fixing methods of waterproof steel plate are: using additional steel bar to fix; The special fixture for the waterproof steel plate is fixed; Lead wire and template fixing, etc., if you need to wear, you can only choose the edge installation area of the waterstop, and the other parts must not be damaged.

The waterproof steel plate is mainly used for foundation projects that are integrated with the concrete structure in the construction joints and deformation joints when the concrete is cast-in-situ, such as underground facilities, tunnel culverts, aqueducts with water conveyance ridges, steel plate waterstop dams, liquid storage structures, etc.

So how to choose a waterproof steel plate manufacturer?

The first choice to choose the waterproof steel plate manufacturer is the credibility of the manufacturer, the reputation of the manufacturer can bring us a reliable guarantee, regardless of the length of the production time, can bring us a very reliable guarantee, and then is to choose the quality of the manufacturer's products, the quality of our use is crucial.

When choosing, it is necessary to check whether there is a twisted part of the waterproof steel plate, if there is a twisted part in use, there may be some problems, we must pay attention to these, the above places are the places to pay special attention to in the selection.

When building the basement, because the concrete of the bottom plate and the exterior wall slab is poured separately, the next time the concrete of the wall slab is poured again, there is a construction joint, and when the position of this joint is below the groundwater level, it is easy to produce water seepage. Set up the waterproof steel plate that is, when pouring the lower layer of concrete, the steel plate of 300*3 is pre-buried, of which the upper part of 10-15cm is exposed outside, and the steel plate of this part is poured into it together when pouring concrete next time, so as to prevent the outside pressure water from penetrating.
