What is the use of water stopping screw water stopping steel plate

Water-stopping screws and water-stopping steel plates are both building accessories, which are used for water-stopping products, mainly used in basements, tunnels and other waterproof projects, and play the role of waterproof and waterproof.

What is the use of water-stopping screw water-stopping steel plateIt can stop water and be waterproof.

The waterproof screw is used for all the walls that need to be waterproofed, the waterproof steel plate is used for all the ground that needs to be waterproofed, and the deformation joints of the ground, and the waterproof screw is used for the walls of pools, basements, garages, subway tunnels, underground pipe corridors, and sewage treatment plants;

The waterproof steel plate is used in the waterproofing of underground structures, dams, reservoirs, swimming pools, roofs and other building materials, expansion joints and deformation joints of buildings. Hope it helps, thank you.

The difference with the ordinary wall screw is that 1. There is a water-stop sheet in the middle of the water-stopping screw; 2. When removing the mold, the ordinary wall screw is extracted as a whole and reused, and the water-stopping screw is sawed off the two ends outside the wall, and the middle section is left in the wall to ensure the impermeability of the wall.

The traditional water-stopping screw is a one-stage structure, usually a whole full-tooth screw, with a water-stop sheet or an expansion water-stop ring welded in the middle to prevent water from passing through the basement wall.

In order to save steel, a new type of water-stopping screw has appeared in the market, which has changed from a one-stage structure to a three-stage structure, also known as a three-stage tension water-stopping screw.

The three-section tension water-stopping screw is composed of an intermediate screw connecting two symmetrical end screws, the middle screw is provided with a water-stopping sheet and two stops, and the end screw is provided with a fastening thread and is equipped with a fastening nut. The two ends of the middle screw are provided with connecting external threads, and one end of the end screw is provided with connecting internal threads and matching with the connecting external threads of the intermediate screw. The junction of middle screw rod and end screw rod is sleeved with tubular cushion block, and the central part of cushion block is a retainer, and one end face of tubular cushion block is arranged along the circumference of a circle of axial columns, and there is a gap between each column.

The end face of the cushion block is provided with a material saving hole. The water-stopping screw that is combined by the middle screw and the end screw segmentation is used for building the concrete pouring mold as well as the ordinary water-stopping screw, and does not need to change the existing construction process, and is easy to popularize and apply. After the concrete pouring is completed and the formwork is removed, the end screw can be removed from the middle screw embedded in the wall, and the end screw of the first can be reused with the new middle screw fit.

The function of the water-stopping screw is to ensure that the width of the wall is not affected when the cross-section is disturbed, because it is through the wall, so it is necessary to add a water-stopping piece, and the role of the water-stopping sheet is to block the infiltration of water from the inside or outside.

The water-stopping screw is usually used in the pouring of the basement shear wall, which plays the role of fixing the template and controlling the thickness of the concrete pouring.

It acts on the concrete of the basement wall or column to fix the template to prevent the mold from bursting, because this rod passes through the wall, and the water is easy to penetrate along the screw, so the water-stopping screw welds a square steel bar in the middle of the screw called the water-stopping piece, which can increase the penetration path of water and play a certain role in stopping water.

In pouring wall or column concrete is to fix the formwork to prevent the violent mold, the reason why it is necessary to stop the water, is because this rod is generally set in the concrete with waterproof requirements, and has a certain waterproof effect of the waterproof screw, by one.

1.Pull the fixed template.

2.Stop water and prevent groundwater from seeping into the room.

It is mainly used for wall underground waterproofing to ensure the integrity of the progress of the project.

Water stop is the function of water stopping, and secondly, the role of Haihan building materials screw is to fix the template on the board wall, so that the thickness of the wall remains unchanged, and at the same time, it has the effect of preventing mold explosion to a certain extent. Hope it helps.

In pouring wall or column concrete, we usually use tension screws, which can play a role in fixing the formwork and preventing the burst of formwork. However, due to the fact that the tie screw passes through the wall, the water is easy to penetrate along the screw, and the waterproof requirements are put forward in the basement and the place where waterproofing is required, in order not to change the original scientific construction mode proven by practice. Therefore, the water-stopping screw welds a square steel bar in the middle of the screw, and changes the water penetration path through the steel bar, that is, the water stop action, I hope to help you. Thank you.

The water-stopping screw is used to fix the template and prevent the formwork from bursting the mold, and it is used in the wall to play the role of water-stopping and waterproofing, and the screw heads at both ends need to be cut after the use of the traditional one-stage water-stopping screw; The outer rod and joint nut of the three-stage water-stopping screw that appeared later can be reused, saving a lot of steel, which is that the water-stopping screw is a loss-making material; It is suitable for walls that need to be waterproofed, and it is also a waterproof material;

The waterproof screw is a waterproof material for building concrete walls, the structure has a one-stage and three-section steel structure, the incision surface is a circular diameter, and a waterproof piece is welded in the middle, which is mainly used for waterproof and waterproofing.

1. The function of the water-stopping screw is to ensure that the width of the wall is not affected when the dust is disturbed, because it is through the wall, so the water-stopping sheet should be added, and the function of the water-stopping sheet is to block the infiltration of water from the inside or outside.

2. The width of the pie is different from the ordinary wall screw in that there is a water-stopping piece in the middle of the water-stopping screw; When removing the mold, the ordinary wall screw is extracted as a whole and reused, and the water-stopping screw is sawed off the two ends outside the wall, and the middle section is left in the wall to ensure the impermeability of the wall. The traditional water-stopping screw is a one-piece structure, usually a whole full-tooth screw, which contains a water-stopping sheet or an expansion water-stop ring in the middle to prevent water from passing through the basement wall.

The scope of application is housing construction, basements, underground pipe corridors, waterworks, oil depots, infrastructure projects, underground facilities, tunnels and roads, sewage early shooting treatment plants, construction projects, building accessories, etc. It is mainly used to reinforce the formwork, prevent the formwork from bursting, reinforcing the formwork, and stopping water.

Water-stopping screw specifications: M12, M14, M16, M18, M20, M22

The water-stopping screw is used in the basement, the underground pipe gallery, the underground garage of Changchang, the civil air defense project, the pool, the sewage treatment plant, etc. are all needed, the role of the coarse water-stopping screw is to fix the template when pouring the concrete of the basement wall or the beam empty ballast column, to prevent the mold from bursting, because the rod passes through the wall, the water is easy to penetrate along the screw, so the water-stopping screw welds a square steel bar in the middle of the screw called the water-stopping piece, which can increase the infiltration path of water and play a certain role in stopping water.

Fix the template when pouring the concrete of the basement wall or column to prevent the mold from bursting, because the rod passes through the wall, and the water is easy to penetrate along the screw, so the water-stopping screw welds a square steel bar in the middle of the screw called the water-stopping cover simple piece, which can increase the penetration path of water and play a certain role in stopping water.

Among the common materials of the water-stopping screw, there are two kinds of round steel and rebar, the water-stopping screw made of these two kinds of steel is not different from the use of the local eggplant, according to the requirements of the construction unit, the material of these two steels is often Q235B, Q345B two, the common material of the three-stage wheel wax preparation type water-stopping screw is often Q235B, this material has strong pressure resistance, but if the water-stopping screw is lower than this material is often undesirable, and we can not distinguish it with the naked eye, It is only obtained when doing a tensile test. In addition, there are 45 steel and so on, which can be purchased according to the material accounting requirements of the project. Hope it helps, thank you.

The raw materials include disc round steel Q235, Q195 waste material and rolled steel and so on. The models of water-stopping screws include three-stage water-stopping screws, through-wire water-stopping screws, double-ended wire water-stopping screws and so on.

The through-wire water-stopping screw is welded on the basis of the screw through the wall, and the water stop sheet in the middle plays the role of water stopping, which must be full welding without water leakage, and the two ends are positioning pieces to support the template instead of cement support. The double-ended wire water-stopping screw is only threaded at both ends of the steel bar, and the rest of the steel is round steel, and the main tensile wall is the water-stopping screw of the Chachatong wire.

The three-stage water-stopping screw is divided into several types, including three-stage sleeve type, conerate type, and empty pipe water-stopping screw. The three-section water-stopping screw is composed of three parts, and the middle of the inner rod is the wall thickness welded water-stopping sheet. The outer rod is a fixed nut for reinforcing the formwork's coarse wire, tooth fixing, and a connecting nut, and different types of connecting nuts.

First, the material of the exterior wall water-stopping screw affects the entire quality of the water-stopping screw, the material is not selected well, the impact on the project is very huge, so when choosing the water-stopping screw, it is necessary to determine what the water-stopping screw is made of, under normal circumstances, the water-stopping screw material is Q235B, of course, there will be Sakura credit Q195, but we can judge from the color, the naked eye can only distinguish the color.

Second, the production process of the water-stopping screw also affects the quality of the water-stopping screw, it is complementary to the good material, the production process such as: the forging of the silk teeth, the welding of the water-stopping sheet, the length of the cutting standard, advanced production equipment, operation standards, etc., these are the factors that affect the quality of the water-stopping screw, in the forging of the water-stopping screw wire tooth, we use a certain standard, including how many silk teeth are rolled out of the mold is not allowed to be used, otherwise it will affect the fit of the screw and the nut, The tightening effect will be good.

Third, the final inspection and tensile test link of the water-stopping screw, of course, is to be established on the excellent material and advanced production technology of the water-stopping screw, and the inspection link is mainly to supervise and test the production process of the hail wheel to see whether the product is qualified, and the responsibility is to the relevant personnel; There is also a very important part of the tensile test.

I hope the above can help you, thank you!

What are the materials of the water-stopping screws? Generally speaking, there are more cast iron, and some use PVC.

The water-stopping screw is a kind of structural form, which has the function of water-stopping. Waterproof screws are generally used for walls that need to be waterproofed, such as basements of construction projects, underground garages, civil air defense projects, pools, sewage treatment plants and other buildings that need to be waterproofed. The water-stopping screw is different from the general wall-piercing screw, there is a welded water-stopping piece in the middle of the water-stopping screw, when the template is disassembled, the water-stopping screw will saw off the two-end screw outside the wall, and the middle part is left on the wall to ensure that the shear wall is not seepage.

and ordinary wall screws need to be pulled out as a whole and can be reused. The water-stopping screw plays the same role as the general wall screw to fix the template. From the appearance, the water-stopping screw is a small square piece welded in the middle, and the threads on both sides are fastened in a trapezoidal buckle, which is not easy to slip.

Like the general wire screw, the whole thread is threaded, and there is no welded water-stop iron sheet in the middle. Both are a kind of construction fasteners that prevent mold explosion and play the role of fixing the template. There is also a three-section screw on the market, a new type of water-stopping screw.

In the common material conjecture of water-stopping screw, there are two types of round steel and Shenna rebar, there is no difference between the water-stopping screw used in these two types of steel water-stopping screw, according to the requirements of each construction unit, the common information of three-stage water-stopping screw Q235B, Q345B two categories, the common data is often Q235B, this data has a strong compressive capacity, however, the hypothetical water-stopping screw under this kind of information is usually undesirable, and we judge with the naked eye, only through the test can know. There are also 45 steel, etc., which can be purchased according to the data accounting requirements of the Kuanmin project.

Hello, what are the material requirements for the basement key mold state water-stop screw?

The material of the water-stopping screw determines its own compressive grade, in addition to the material factor, it is also related to the diameter of the water-stopping screw, the height of the wall, and the water-stopping screw of each square layout, which should be calculated in advance, the commonly used material is Q235B, a higher one has Q345B, for special buildings, the material requirements may be higher. Hope it helps, thank you.

Hello, the quality requirements of the basement water-stopping screw:
