Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building walls, in particular to the technical field of concrete shear walls, and specifically provides an anti-seepage concrete shear wall structure. Background Technique
[0002] With the improvement of people's requirements for building structures, most building structures basically involve underground structures, including basements, underground civil air defenses, underground shopping malls, underground parking lots, underground water tanks, septic tanks, etc. The above structures all need to use concrete and steel bars to form a concrete shear wall structure, as Figure 1 shown. The construction process of the traditional concrete shear wall structure is wall steel bar binding - support rod installation - protective layer cushion block binding - water stop screw installation - shear wall formwork installation. The wall steel bars include multiple wall horizontal steel bars and multiple wall vertical steel bars. After the wall steel bars are bound, the whole is in a grid shape, but the mesh size of the bound wall steel bars is relatively large. Therefore, after the concrete is poured, as the water in the concrete is lost and the concrete solidifies and shrinks, cracks or fissures of varying degrees are likely to appear on the wall surface of the concrete shear wall, directly causing water vapor to contact the wall steel bars along the cracks or fissures, resulting in the corrosion of the wall steel bars, thus affecting the service life of the concrete shear wall, and at the same time causing water seepage and leakage in the underground space. To avoid water seepage in the concrete shear wall, operators usually nail an anti-cracking wire mesh (the anti-cracking wire mesh includes anti-cracking horizontal bars and anti-cracking vertical bars) to the wall surface of the concrete shear wall with steel nails after the shear wall formwork is removed, and then apply waterproof mortar on the wall surface of the concrete shear wall to form an anti-seepage concrete shear wall structure. However, this method has many construction procedures and high construction costs. Summary of the Invention
[0003] The utility model aims to solve the problems of many construction procedures and high construction costs of the traditional anti-seepage concrete shear wall structure, and thus provides a new anti-seepage concrete shear wall structure.
[0004] The utility model is realized by adopting the following technical scheme:
[0005] An anti-seepage concrete shear wall structure includes wall reinforcement bars, a plurality of water-stop screws, an inner anti-cracking wire mesh and an outer anti-cracking wire mesh which are both vertically arranged. The wall reinforcement bars include a plurality of wall horizontal reinforcement bars and a plurality of wall vertical reinforcement bars. Rubber plugs are provided at both ends of each water-stop screw. The inner anti-cracking wire mesh includes a plurality of inner anti-cracking horizontal bars and a plurality of inner anti-cracking vertical bars. The outer anti-cracking wire mesh includes a plurality of outer anti-cracking horizontal bars and a plurality of outer anti-cracking vertical bars. The inner anti-cracking wire mesh and the outer anti-cracking wire mesh are respectively located on the outer sides of the front and rear ends (the front and rear directions in this application are the thickness direction of the concrete shear wall) of the wall reinforcement bars. (In this application, the inner side refers to the side close to the center side in the thickness direction of the concrete shear wall, and the outer side refers to the side far from the center side in the thickness direction of the concrete shear wall). Inner anti-cracking clamps and outer anti-cracking clamps for clamping the inner anti-cracking horizontal bars and the outer anti-cracking horizontal bars are respectively fixed on the circumferential walls at both ends of each water-stop screw. The inner anti-cracking clamps and the outer anti-cracking clamps are respectively located on the circumferential walls of the corresponding water-stop screws close to the inner sides of the two rubber plugs. Inner steel bar clamps and outer steel bar clamps for further positioning the front and rear ends of the tied wall horizontal reinforcement bars are also fixed on the circumferential walls at both ends of each water-stop screw.
[0006] The construction steps of the anti-seepage concrete shear wall are as follows: 1) Binding of wall reinforcement bars; 2) Installation of water-stop screws, and at the same time positioning the two ends of the wall horizontal reinforcement bars on the inner steel bar clamps and the outer steel bar clamps, ensuring the position of the reinforcement bars and reducing the use of protective layer cushion blocks; 3) Clamping the inner anti-cracking horizontal bars and the outer anti-cracking horizontal bars on the corresponding inner anti-cracking clamps and outer anti-cracking clamps respectively to prevent the inner anti-cracking wire mesh and the outer anti-cracking wire mesh from closely adhering to the wall reinforcement bars (which cannot play an anti-cracking role) or closely adhering to the formwork (which will expose the reinforcement bars); 4) Installation of shear wall formwork; 5) Pouring of anti-seepage concrete; 6) Demolition of shear wall formwork.
[0007] Principle description: In a traditional concrete wall, there are only wall reinforcement bars, and the mesh size of the wall reinforcement bars is relatively large, so the wall is prone to cracking. Therefore, after the shear wall formwork is demolished, it is necessary to add an anti-cracking wire mesh and apply waterproof mortar. However, in this utility model, the anti-cracking wire mesh is added to the concrete wall, and due to the relatively small mesh size of the anti-cracking wire mesh, it can play a good role in preventing cracking; at the same time, the water-stop screws originally existing in the concrete wall are used to fix the anti-cracking wire mesh, and the structure is simple and effective.
[0008] Furthermore, both the inner anti-cracking clamps and the outer anti-cracking clamps are composed of two first vertical reinforcement bars fixed on the upper part of the circumferential wall of the water-stop screw. The distance between the two first vertical reinforcement bars is adapted to the inner anti-cracking horizontal bar or the outer anti-cracking horizontal bar, ensuring that the inner anti-cracking horizontal bar and the outer anti-cracking horizontal bar do not shift in the thickness direction of the anti-seepage concrete shear wall.
[0009] Further, both the inner steel bar fixture and the outer steel bar fixture are composed of two second vertical steel bars fixed to the lower part of the circumferential wall of the water-stop screw. The distance between the two second vertical steel bars is adapted to the wall horizontal steel bars. After the wall steel bars are tied, when installing the water-stop screw, the front and rear positions of the water-stop screw can be determined according to the positions of the tied wall steel bars, and then the positions of the wall steel bars are further positioned through the inner steel bar fixture and the outer steel bar fixture.
[0010] Further, the mesh size of the inner anti-cracking wire mesh and the outer anti-cracking wire mesh is 5 cm × 5 cm. The anti-cracking wire mesh with this mesh size can effectively prevent the cracking of the concrete shear wall.
[0011] Further, the diameters of the inner anti-cracking horizontal steel bars, the inner anti-cracking vertical steel bars, the outer anti-cracking horizontal steel bars, and the outer anti-cracking vertical steel bars are all 2-3 mm. The thinner steel bar bodies can further prevent the cracking of the concrete shear wall.
[0012] The beneficial effects produced by the present utility model are as follows: The anti-seepage concrete shear wall structure of the present utility model reduces the material cost and installation cost of the protective layer cushion blocks and struts. And by installing the inner anti-cracking wire mesh and the outer one in the shear wall before removing the shear wall formwork, not only the problem of wall surface cracking of the concrete shear wall is eliminated, but also the situation of water seepage in the concrete shear wall is effectively avoided from the root, improving the overall quality of the concrete shear wall. At the same time, the process of applying waterproof mortar to the surface of the concrete wall after removing the shear wall formwork is also saved, saving the construction period and reducing the construction cost.

[0026] Such as Figure 2-6As shown in the figure, an anti-seepage concrete shear wall structure includes wall reinforcement bars, a plurality of water-stop screws 1, an inner anti-cracking wire mesh 56 and an outer anti-cracking wire mesh 78 which are both vertically arranged. The wall reinforcement bars include a plurality of wall horizontal reinforcement bars 3 and a plurality of wall vertical reinforcement bars 4. Rubber plugs 2 are provided at both ends of each water-stop screw 1. The inner anti-cracking wire mesh 56 includes a plurality of inner anti-cracking horizontal bars 5 and a plurality of inner anti-cracking vertical bars 6. The outer anti-cracking wire mesh 78 includes a plurality of outer anti-cracking horizontal bars 7 and a plurality of outer anti-cracking vertical bars 8. The inner anti-cracking wire mesh 56 and the outer anti-cracking wire mesh 78 are respectively located on the outer sides of the front and rear ends (the front and rear directions in this application are the thickness direction of the concrete shear wall) of the wall reinforcement bars. (In this application, the inner side refers to the side close to the center side in the thickness direction of the concrete shear wall, and the outer side in this application refers to the side far from the center side in the thickness direction of the concrete shear wall). Inner anti-cracking fixtures 9 and outer anti-cracking fixtures 10 for clamping the inner anti-cracking horizontal bars 5 and the outer anti-cracking horizontal bars 7 are respectively fixed on the circumferential walls at both ends of each water-stop screw 1. The inner anti-cracking fixtures 9 and the outer anti-cracking fixtures 10 are respectively located on the circumferential walls of the corresponding water-stop screws 1 close to the inner sides of the two rubber plugs 2. Inner reinforcement fixtures 11 and outer reinforcement fixtures 12 for further positioning the front and rear ends of the tied wall horizontal reinforcement bars 3 are also fixed on the circumferential walls at both ends of each water-stop screw 1.
[0027] The construction steps of the anti-seepage concrete shear wall are as follows: 1) Binding of wall reinforcement bars; 2) Installing the water-stop screw 1, and at the same time positioning the two ends of the wall horizontal reinforcement bar 3 on the inner reinforcement fixture 11 and the outer reinforcement fixture 12, ensuring the position of the reinforcement bars and reducing the use of protective layer pads; 3) Clamping the inner anti-cracking horizontal bar 5 and the outer anti-cracking horizontal bar 7 on the corresponding inner anti-cracking fixture 9 and outer anti-cracking fixture 10 respectively to prevent the inner anti-cracking wire mesh 56 and the outer anti-cracking wire mesh 78 from closely adhering to the wall reinforcement bars (which cannot play an anti-cracking role) or closely adhering to the formwork (which will cause exposed reinforcement); 4) Installing the shear wall formwork; 5) Pouring anti-seepage concrete; 6) Removing the shear wall formwork.
[0028] During specific implementation, both the inner anti-cracking fixture 9 and the outer anti-cracking fixture 10 are composed of two first vertical reinforcement bars fixed on the upper part of the circumferential wall of the water-stop screw 1. The distance between the two first vertical reinforcement bars is adapted to the inner anti-cracking horizontal bar 5 or the outer anti-cracking horizontal bar 7, ensuring that the inner anti-cracking horizontal bar 5 and the outer anti-cracking horizontal bar 7 do not shift in the thickness direction of the anti-seepage concrete shear wall.
[0029] In specific implementation, both the inner steel bar fixture 11 and the outer steel bar fixture 12 are composed of two second vertical steel bars fixed to the lower part of the circumferential wall of the water stop screw 1. The distance between the two second vertical steel bars is adapted to the wall horizontal steel bar 3. After the wall steel bars are tied, when installing the water stop screw 1, the front and rear positions of the water stop screw 1 can be determined according to the positions of the tied wall steel bars, and then the positions of the wall steel bars are further positioned through the inner steel bar fixture 11 and the outer steel bar fixture 12.
[0030] In this specific implementation manner, the mesh sizes of the inner anti-cracking wire mesh 56 and the outer anti-cracking wire mesh 78 are 5 cm × 5 cm. The anti-cracking wire mesh with such a mesh size can effectively prevent the cracking of the concrete shear wall.
