What is the difference between a steel plate waterstop and a metal waterstop?

Hello, steel plate waterstop.

The differences from metal waterstops are as follows:

The concrete of the steel plate waterstop box foundation or basement, the bottom plate and the exterior wall plate are poured separately, and the next time the wall plate concrete is poured again, there is a construction joint.

When this crack is located below the water table, it is prone to 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. That is, when pouring the lower layer of concrete, the 300*3 steel plate is pre-embedded, of which the upper part of 10-15cm is exposed outside, and the steel plate of this part is poured into it together when the concrete is poured next time, so as to prevent the outside pressure water from seeping in.

The thickness of the steel plate waterstop is generally 2mm thick and 3mm thick.

The metal waterstop adopts a metal plate waterstop, which 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.

Steel waterstops and metal waterstops are one thing, but they are not the same material.

Water-stopping steel plate: The "opening tooth" of the water-stopping steel plate faces the head-on, and the steel plate is tightly separated from the concrete, supplemented by the figure-eight shape of the steel plate, and it is difficult for open water to penetrate from the steel plate along the construction joint.

Waterstop: The waterstop is a strip that avoids preventing water soaking and manufactures a device, with a width of 200-350, selected according to the design, appropriately extending the seepage diameter, partially or completely buried in the concrete during the concrete pouring process, with a certain strength and toughness, and its strength and toughness are between the waterstop strip and the waterproof steel plate.

The price of the water-stopping steel plate is higher, the construction difficulty is greater, the water-stopping effect is good, and it is generally suitable for the vertical and degree construction joints below the open water level, because its stiffness is too large, it is not suitable for use in the part with large deformation; The price, performance, and construction difficulty of the waterstop are moderate, and the application range is wide, and because of its large toughness, it is more suitable for use in the parts with settlement deformation requirements with large deformation.

If you want to know more about the waterstop, we recommend Hengding rubber. Hengding Rubber has modern production equipment, strong technical force, is a professional rubber waterproof material manufacturers, since the establishment of the company, with high-quality products, excellence in service, has won the trust and favor of the majority of users. With strong strength, reasonable and excellent service to meet the needs of new and old users.

Waterstops and waterstops are both waterstop products in building accessories, and the main differences are:

The shape is different, the water-stop bandwidth is thick, and the water-stop strip is slender.

The use position is different: the waterstop is used in the deformation joints and expansion joints of concrete pouring, and the waterstop strips are used in the construction joints and expands when exposed to water.

The water-stop steel plate refers to the waterstop made of steel plate.

The thickness of the water-stopping steel plate is ordinary 3, the width is 200, and the length is generally processed into 3 meters long or 6 meters long, and it is generally three meters good for transportation. During construction, try your best to ensure that the water-stopping steel plate is on the center line of the wall; The welding between the two steel plates should be plump and double-sided welding, and the lap of the steel plate should not be less than 200mm. The disposal of the corner of the wall usually adopts the bending of the whole steel plate, T-shaped welding, 7-shaped welding, etc.

The support welding of the waterproof steel plate can be welded on the main reinforcement with small steel bars; When the waterproof steel plate passes through the column stirrups, the stirrups that pass through can be broken and manufactured into a tooth stirrup, which is welded on the steel plate.

Analysis of advantages and disadvantages: the joint part of the steel plate waterstop is required to be welded, and the effect is of course very good, but the cost is much higher, and the construction speed is relatively slow. The standard request, the use of water-stopping steel plate shear wall, the wall thickness should not be less than 250, the net interval between the water-stop steel plate and the steel bar is:

Wall thickness 2 - outer maintenance layer thickness 50 - wall two-way steel bar diameter; When the wall thickness is 250, 250 2-50-30=45. The interval between the waterproof steel plate and the wall is small, and the concrete is easy to leak vibration in this part during construction, forming a honeycomb hole. Therefore, when using the waterproof steel plate, the vibration must be enhanced at the construction joint.

The thin part of this water stop measure is the lap part and the 90° corner part. It is extremely difficult to control the weld at the 90° corner of the steel plate, and it is easy to form a leakage point. The welding construction of the corner part of the steel plate should be controlled as the key part of the process.

The waterstop has additional steel bar fixing method, special fixture fixing method, lead wire and formwork fixing method, etc. If perforation is required, it can only be used in the edge installation area of the waterstop, and no other parts should be damaged. If on-site bonding is required, electric heating plate vulcanization bonding or cold bonding (rubber waterstop) or welding (plastic waterstop) can be used.

During the construction of the waterstop, it should not be exposed to the open air for a long time, avoid rain, and do not come into contact with polluting chemicals; In transportation and construction, avoid mechanical and steel damage to the waterstop; During the construction process, the waterstop must be firmly fixed to prevent displacement when pouring concrete, and ensure the correct position of the waterstop in the concrete;

Analysis of advantages and disadvantages: there are many sharp corners of stones and sharp steel heads in concrete, because the tear strength of plastic and rubber is 3 5 times lower than the tensile strength, once the waterstop is punctured or torn, there is no need for great external force, the crack will expand, so in the waterstop positioning and concrete pouring process, we should pay attention to the positioning method and pouring pressure, so as not to puncture the waterstop and affect the waterstop effect. When pouring concrete, because the waterstop is soft for rubber products, it is easy to deform, not straight, and the upper and lower widths are not easy to control.

The waterproof steel plate used in the project has played an indispensable role in the waterproof control of our settlement joints, which is a posture that can not be opened by a husband and a woman, and when pouring concrete in a large area in the project, it is always impossible to form a one-time type, and the time of two concrete pouring is different, so there is a construction joint this product, it is precisely this point that is the weakest place in the waterproof link, at this time there must be a medium to achieve good adhesion of concrete on both sides, and this time can only be supported by the waterproof steel plateThe water-stopping steel plate acts as a medium connecting the old and new concrete, so that it is easy to strengthen between the concrete, so that the effect of water-stopping will not be too bad, and the settlement joint will not become fragile due to weathering.

Although the water-stopping steel plate used in the project is obvious, but improper use will affect the water-stopping performance of the water-stopping steel plate.

The waterproof steel plate has made a very great contribution to the waterproofing of our building, but we are not recommended to weld in rain, snow, and fog during construction, these kinds of weather will increase the humidity in the air, and the weld will be mixed with a certain amount of water vapor when welding, so that the quality of welding will be reduced, and the connection between the steel plates will not be firm.

When installing this step, try to lengthen the steel plate, which can reduce the amount of welding between the steel plates in the later stage. The specification of the commonly used waterproof steel plate on the market is 3 meters long, and the length of the waterproof steel plate can be customized according to the engineering requirements to facilitate construction. After the installation of the waterproof steel plate, it is difficult to weld in some connected places, and skilled welders should be arranged to weld at this time.

There is another thing we have to say about the waterproof steel plate, that is, the waterproof steel plate is relatively easy to rust, like the rainy day, snow day and foggy day I mentioned above, it is easy to make the waterproof steel plate rust; The rusty waterproof steel plate is troublesome in the post-processing, and if it is more serious, it cannot be used for normal construction. Therefore, it is necessary to choose a suitable placement environment when storing, otherwise the construction period will be delayed because of the rust of the waterproof steel plate, but the gain will outweigh the loss!

If the construction is in a humid area, it is recommended to use galvanized waterproof steel plate for the project, the galvanized waterproof steel plate is the waterproof steel plate after the galvanizing process, called the galvanized waterproof steel plate, the surface is a kind of red, forming a protective film on the surface of the product, isolating air and water, galvanized waterproof steel plate will also have good waterproof property in the humid environment for a long time, and the service life of the product can meet the requirements of the project, so that the project becomes indestructible and improves the overall drainage effect.

They are all water-stopping, and the materials are different.

Hello, what is the difference between the waterstop strip, the waterstop steel plate and the waterstop?

The waterstop strip can be used for underground buildings without water, the waterproof steel plate can be used for buildings with water such as pools, and the rubber waterstop can be used for vertical waterstop and expansion joints, settlement joints and other places. The waterstop strip is a round long strip, the construction is simple, but the water-stopping effect is not as good as the water-stopping belt and the water-stopping steel plate, the construction unit often likes to use the water-stop strip for convenience, and when the foundation pouring is completed, it can be pressed on the surface of the wall concrete pouring. The waterstop is generally available with a type of waterstop, the width varies from 200-350, according to the design selection, the waterstop effect is better, the seepage diameter is extended, the disadvantage is that when the concrete is poured, because the waterstop is a rubber product is soft, easy to deform, not straight, the upper and lower width is not easy to control, if the lead wire is tied to the steel bar, damage the waterstop, so the construction unit generally feels troublesome and does not like to use.

The effect of the waterproof steel plate is also better, the installation is more convenient, and it is more straight. Hope it helps, thank you.

Steel plate waterstop can also be called metal plate waterstop, waterproof steel plate, is a waterproof material commonly used in engineering, including steel plate, copper plate, alloy steel plate and so on. In the protection project, the use of metal plate waterstop can ensure the protection effect of the project. Next, let's take a look at the difference between steel plate waterstop and rubber waterstop, what part of steel plate waterstop is used and the relevant content of steel plate waterstop specifications and models, I hope it can help you.

Steel plate waterstop is a waterproof material that can be used in construction projects. It is usually made of steel and rubber, which prevents water from seeping through the cracks in the building and ensures the waterproofing of the building. [Click to get real-time from the manufacturer**].

Advantages of steel plate waterstops:

Compared with traditional waterproofing materials, steel plate waterstop belts have many advantages. First of all, it is very easy to install and does not require the same amount of time and money as traditional waterproofing materials. Secondly, it has a long service life and can still maintain the waterproof effect after 10 years of use.

In addition, due to the excellent physical properties of the steel plate, the stress strength of the steel plate waterstop is higher and it has better impact resistance.

Sheet steel waterstops are relatively easy to install, often requiring shearing at the building material storage site and customizing them to the architectural design requirements. Before installation, the construction area needs to be cleaned and treated. When using the steel plate waterstop for construction, the waterstop needs to be placed above the original construction area first, and then the installation of concrete embedded moving parts is carried out, and finally the prestressed anchorage and reinforced concrete pouring are carried out, and the edge position of the steel plate waterstop is guaranteed to remain unchanged in this process, so as to prevent errors and affect the waterproof effect of the project.
