rubber waterstop

Description of rubber waterstop

Waterstop also known as seal gap band, buildings or underground structure with seams of shaped sealing material. It is characteristics of high elasticity of the rubber and compression deformation of, under various loads generate elastic deformation, so as to effectively fastening and sealing, impermeable leakproof function. In the construction, due to the inability of continuous casting, foundation deformation, leaving some construction crack, deformation crack, in these gaps must install sealing bring to prevent water leakage problems.

The product is mainly used in rubber as the main material with good elasticity, good elasticity, good ageing resistance, low compression deformation and good tear resistance.

The main purpose of rubber waterstop

A: mainly used in infrastructure projects, underground facilities, tunnel, culvert, water conservancy, subway and other projects.

B: door, base, construction engineering, underground buildings with concrete expansion.

The types of rubber waterstops:

Our factory can be in the production of rubber, plastic type, ordinary type, water swellable type and adhesive type, alloy type water stop belt products, can also be processed planar cross type, planar T-shaped, three-dimensional tee type a variety of different style of the waterstop type get.

Design and selection of the waterstop, construction and installation:

1. The waterstop choice: should be according to the importance level of the building, the deformation joint deformation and water pressure, water stop enable (should) work environment, economic factors and other conditions to determine the comprehensive consideration.

2. the waterstop material selection according to the following provisions

(1) the waterstop material selection must consider the contact medium (such as acid, alkali, salt, oil, solvent and all kinds of corrosive gas) of waterstop corrosion. In case of weak acid, alkali corrosion medium timely selection of chloroprene rubber waterstop, in case of oil corrosion medium should be chosen nitrile rubber sealing belt.

(2). When the case of mould erosion may be, should consider the mold with the rubber seal, the level should reach level 2 and level 2 or above.

(3) of the waterstop material selection should take into account the conditions of use, such as the influence of temperature, ultraviolet ray and ozone aging, repeated deformation etc. factors. Under the low temperature should be selected ternary ethylene propylene rubber sealing belt.

3 .strip width and the thickness of the choice to consider the following three factors

(1) the horizontal and vertical deformation of the deformation joints (2) water pressure (3) structure section size

4 .check the width and thickness of the water level and the vertical deformation and deformation of the reference table right - note: .available,the other one means right 

5. when the structure section size greater than 500 mm, the width of the waterstop shall not be less than 300 mm.

6. And stop supporting the use of filling in and sealing material should consider the following factors: deformation joint of relative deformation, with the size of the water pressure, contact medium. Use environmental conditions, and build a surface decoration, the size and cost of concrete section. Optional with sealing plate with PTFE foam board, anti-corrosion soft wood, fibreboard, such as can meet the engineering needs of the various boards, seal material can be selected polysulfide rubber, polyurethane, silicone rubber, waterproof, adequate deformation capacity, and the concrete has good adhesive properties of flexible material.

7. rubber waterstop construction and installation

Sealing strip is in pouring process of concrete pouring in whole or in part buried in concrete. Because there are many sharp stones and sharp reinforced concrete, so in sealing thing orientation and concrete pouring and tamping process should be pay attention to installation positioning method and pouring tamping pressure, to avoid the waterstop is punctured. Due to the plastic and rubber tearing strength than tensile strength low 3 to 5 times, so if the spiny water stop breaking will greatly ability of reducing the waterstop resistance force. To help in the construction to the grid at the note. Specific considerations are as follows:

In assembling reinforcement and formwork, waterstop must take reliable measures of fixing and avoid displacement occurred in the concrete pouring, ensure the sealing strips in the correct position of the concrete. Construction plans

(1) in the assembling reinforcement and formwork, the waterstop must take reliable measures of fixing and avoid displacement occurred in the concrete pouring, ensure the sealing strips in the correct position of the concrete.

(2) fixed sealing strip, only in the waterstop allows parts of perforated holes, shall not damage the body parts.

(3) the waterstop fixation should be in accordance with the requirements of the design and construction specification for fixed method commonly used in: using additional reinforcement fixation; special fixture fixed; with the wire and template fixed. No matter what fixation method is adopted, must ensure waterstop positioning accuracy, and does not damage the waterstop effective part and convenient concrete pouring and tamping.

(4) water stop belt should be as far as possible in the factory are connected into a whole. As for manufacturing process, transport conditions and other restrictions, in the field of connection should be by hot pressing vulcanization glue (rubber waterstop) or welding (of the plastic waterstop), and the joint appearance should be smooth, tensile strength is not low wire rod without any treatment of the so-called "overlap" is absolutely not allowed.

(5) waterstop various cross junction, the factory production into parts, to ensure the site under construction in a direct connection only.

(6) in the delivery, can provide the corresponding specifications Zhishui connected with the mold, technical personnel along at any time to guide the construction site, according to the actual situation, buyer can contact with my factory.
