How to calculate the water stopping steel plate and the water stopping screw

First, the water-stopping steel plate can be calculated by meters or tons, usually we know how much water-stopping steel plate per meter is good to calculate others, the weight formula per meter: density) that is, we know: thickness:

Kilogram meter thickness: kilogram meter, the premise is that we have to know what specifications of waterproof steel plate we need before we can calculate how much a certain specification of waterproof steel plate is a meter.

Second, the calculation of the water-stopping screw, do you want to know how to calculate the water-stopping screw? Or do you want to know how to calculate the diameter and length of the water-stopping screw? For example, according to the ** to calculate the water-stopping screw, take the traditional old-fashioned water-stopping screw as an example.

The type of water-stopping screw is determined by the type of water-stopping screw, and the material cost and processing cost of each component of the water-stopping screw are composed. Calculation of one-stage water-stopping screw**: screw length * unit price + water-stop positioning piece + processing fee (wire tooth processing + water-stop welding), and three-stage water-stopping screw ** calculation:

Inner rod cost + outer rod cost * 2 + joint nut cost * 2 + processing fee (wire processing + water stop welding).

How to calculate the spacing of the waterstop screw of the basement shear wall?

According to the express provisions of the State Engineering Quality Supervision Bureau: the spacing between the top and bottom of the wall water-stopping screw shall not exceed 40-50 cm, so the specific spacing of the water-stopping screw should be adjusted within the specified range.

How to calculate the engineering amount of the basement shear wall waterstop screw?

The length of the engineering wall The spacing of the water-stopping screw [left and right] quotient.

The width of the wall of the commercial project, the spacing between the upper and lower water-stopping screws, and the amount of water-stopping bolts.

Calculation of the weight of the waterproof steel plate.

The density of the waterproof steel plate of the commonly used material is 7850kg per cubic meter, and the formula for calculating the theoretical weight is as follows

Thickness (mm) x area (m) = weight of steel Weipai slide plate (tons) of course, it can also be calculated according to kg.

Weight per meter formula for water-stopping steel plate:

Thickness: kg m Thickness: kg m.

Thickness: kg m Thickness: kg m.

Thickness: kg m Thickness: kg m.

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 number of water-stopping screws is calculated according to the following three points:

1. According to the height of the slab wall, calculate what is the lateral pressure generated by the concrete per unit area on the formwork?

2. According to the side pressure and the tensile force value of the screw, calculate the spacing used in the configuration screw.

3. According to the spacing and the area of the plate wall, the total amount of the required water-stopping screw can be calculated;

According to the above three points, the number of water-stopping screws required for construction projects can be calculated, and the length of water-stopping screws used in construction projects is calculated and related to the thickness of the wall.

The calculation method of the water-stopping screw can be divided into the part inside the wall + template + wood square + steel pipe + mountain card + nut, and part of it is the part that is exposed outside.

The water-stopping screw is divided into two kinds, one is the old-fashioned water-stopping screw and the other is the three-stage water-stopping screw, these two are basically the same, the only difference is that the three-section water-stopping screw has one more nut.

The details can be analysed using a reference material.

Calculate how many three-section water-stopping bolts can be used in a project, and calculate the amount according to the overall area of the project, the height and width of the wall. How to calculate the amount of three-stage water-stopping screw in a project? Although the three-stage water-stopping screw is a little more expensive than the traditional water-stopping screw, many construction sites will give preference to the three-stage water-stopping screw, and the construction site should plan in the long run, and the economic benefits brought by the comprehensive comparison of the new three-stage water-stopping screw far exceed the traditional water-stopping screw.

Songmao building materials three-stage water-stopping screw in the middle of the water-stopping piece, we use the second welding machine for the welding of the water-stopping sheet, the welding effect is very good, and it is double-sided full welding (double-sided welding or single-sided welding can be selected according to the user), no loopholes, tin slag, uneven phenomenon, but also greatly improve the artificial efficiency, more favorable is to improve the welding process of the water-stopping piece. The water-stopping effect has been qualitatively improved.

The role and nature of the three-section water-stopping screw are valued by many construction workers, especially in the construction industry, which is very extensive.

The water-stopping screw is calculated by meters**, and it is equipped with a mountain card water-stopping sheet and water-stopping pad.

Answer: Hello, how to calculate the water-stopping screw? This involves the calculation of the use diameter, length and quantity of the water-stopping screw, please see the following: Calculation of the diameter of the water-stopping screw The selection of the diameter of the water-stopping screw has nothing to do with the thickness of the wall, but has a close relationship with the height of the wall.

For example, for walls under 5 meters, we will recommend customers to use a 12mm diameter waterstop screw. 5-7 m walls can use 14mm diameter water-stopping screws, the higher the wall, the larger the diameter. Secondly, the thickness of the wall will only determine the number of water-stopping screws per square meter, not its diameter.

Calculation of the length of the water-stopping screw Here we want to distinguish the length of the one-stage and three-section water-stopping screw, in which the length of the three-section water-stopping screw is based on the width of the board wall plus the length of the two outer rods, and the length of the outer rod 23cm is fixed, and the general length of the three-section water-stopping screw is the width of the board wall.

Hello, how to calculate the water-stopping screw?

Take an example of the pipe gallery project, it will be clear at a glance, assuming that the underground pipe gallery wall is 4 meters high, the wall is 30 cm wide, and the total construction area is 30,000 square meters, then the relevant conditions have been listed during the construction, that is to say, the water-stopping screw with a diameter of 12 centimeters is required, the length of the inner rod is 30 cm, and the outer rod is a turnover and a fixed length of 23 cm, according to the design requirements of 3 per square meter of layout, 30,000 square meters of construction area plus quota loss, 5,000 sets (full set of internal and external rods) can be purchased in the early stage, The use of the remaining only tens of thousands of inner rods can be purchased, carefully calculated, but a lot of costs are saved. How is it calculated? It is to calculate effectively and achieve the effect of cost savings.

Hope it helps, thank you.

Here we want to distinguish the length of the one-stage and three-section water-stopping screws, wherein the length of the three-section water-stopping screw is based on the width of the board wall plus the length of the two outer rods, and the length of the outer rod 23cm is fixed, and the general length of the three-section water-stopping screw is the width of the board wall; The length of the one-stage water-stopping screw is added to the width of the board wall by 40cm, which is convenient for the screw cutting operation after the wall is formed. And such a length is within a reasonable range, and over time it becomes a quota data. Hope it helps, thank you.

The length of the water-stopping screw is calculated according to the width of the wall, and the general wall width plus 400mm is the length of the water-stopping screw.

If the wall is higher, the diameter of the water-stopping screw will be larger.

The length of the water-stopping screw used in the construction project is determined according to the thickness of the wall, for example, the thickness of the concrete wall you need to pour is 300mm, then the middle water-stopping screw is 300mm, plus the thickness of the formwork at both ends, the diameter of the steel pipe, the thickness of the square wood, and the thickness of the mountain card and nut, and a section of exposed length, almost 230-250mm, because it is both ends, so two such lengths should be added. The total length is almost 700-800. The diameter of the water-stopping screw is determined by the height of the wall, usually the height of the outer wall below 5 meters can use the water-stopping screw with a diameter of 12mm, and the water-stopping screw with a diameter of 14mm can be used for 5-7 meters.

The length of the water-stopping screw is determined by the thickness of the wall. The length of the screw is usually the width between the board walls plus 40cm, and the exposed screw can be cut and removed after the construction is completed. The length of the outer rod of the three-section water-stopping screw is fixed, which is 23cm, and the inner rod of different lengths can be used according to the different thickness of the wall.

If it is to be expressed by a calculation formula, the length of the general water-stopping screw can be expressed as: wall thickness plus 2 * (thickness of the template + thickness of the double-layer keel of the template + length reserved by the nut + length reserved by the bolt).

The quota of the water-stopping screw sleeve is generally calculated by technicians on the site in the early stage;

For example, the use of water-stopping screws diameter, use length, use spacing, use methods, etc., such as the use of a diameter of 12 water-stopping screws for walls below 5m, the use of 70cm long water-stopping screws for 30cm plate walls, the use of 2-5 water-stopping screws per square meter, etc., these are very easy to calculate, through the concrete side pressure calculation and so on, you can search for my name to find me in detail.
