Technical Field

[0001] This utility model relates to the technical field of waterproofing of splice nodes of composite shear walls, and in particular to a waterproof structure for composite shear walls. Background Technology

[0002] Composite shear walls are composed of two layers of precast reinforced concrete slabs connected by truss reinforcement or connectors to form a wall panel component with a central cavity. After on-site installation, concrete is poured to fill the central cavity to form a concrete wall panel.

[0003] During the construction of composite shear walls, a straight gap will be formed between the two composite shear walls. To prevent water from seeping into the wall through the gap, waterproofing measures are a key factor. Traditional waterproofing measures involve applying waterproof coatings and membranes at the joints. However, due to the limited durability of the waterproof coatings and membranes, the waterproofing effect is relatively poor. Currently, there is a lack of a waterproofing measure that can completely block water seepage at the joints of composite shear walls. Utility Model Content

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0013] Example

[0014] Please see Figures 1-5This utility model discloses a waterproof structure for a composite shear wall, comprising a composite shear wall 1, a composite shear wall 2, and a water-blocking partition 3. The water-blocking partition 3 is disposed between the composite shear wall 1 and the composite shear wall 2. Limiting platforms 4 are integrally connected to both the front and rear ends of the water-blocking partition 3. The upper and lower ends of the limiting platforms 4 are aligned with the upper and lower ends of the water-blocking partition 3. Multiple connecting screw holes 5 are equidistantly provided on the outer side of the limiting platforms 4. Stepped grooves 6 are provided on both sides of the joint between the composite shear wall 1 and the composite shear wall 2. The composite shear wall 1 and the composite shear wall 2 are joined to the left and right sides of the water-blocking partition 3 by the cooperation of the limiting platforms 4 and the inner sides of the stepped grooves 6. A waterproof sealing strip 7 is fixedly connected to each step surface of the stepped groove 6 parallel to the front end of the limiting platform 4. Two adjacent sets of steps at the joint between the composite shear wall 1 and the composite shear wall 2 are connected together. T-shaped sealing covers 8 are installed between the ladder grooves 6. The inner side of the T-shaped sealing cover 8 has a slot 9 that mates with the limiting platform 4 and runs vertically through the slot 9. The outer side of the T-shaped sealing cover 8 has multiple bolt holes 10 that are equidistant from each other and communicate with the slot 9. The bolt holes 10 correspond to the mating screw holes 5. A half-threaded cover bolt 11 is inserted into each bolt hole 10. The T-shaped sealing cover 8 is fixedly connected to the limiting platform 4 by the mating of the half-threaded cover bolt 11 and the mating screw hole 5. In use, the water-blocking baffle 3 blocks the water at the joint of the composite shear wall 1 and the composite shear wall 2, and the T-shaped sealing cover 8 seals the joint between the water-blocking baffle 3 and the composite shear wall 1 and the composite shear wall 2, which can improve the waterproof sealing effect of the composite shear wall joint and prevent water seepage at the joint.

[0015] The bolt hole 10 adopts a countersunk hole structure, and the half-thread cover plate bolt 11 uses an internal hex bolt. By adopting a countersunk hole structure and using internal hex bolts for mating, the tightness of the bolt connection can be improved, the outside of the T-shaped sealing cover plate 8 is flatter, the bolt head is prevented from protruding, and the aesthetics are improved.

[0016] The waterproof sealing strip 7 is made of ethylene propylene rubber. By using ethylene propylene rubber, the waterproof sealing strip 7 has good weather resistance, aging resistance and elasticity, thereby improving the sealing performance of the waterproof sealing strip 7.

[0017] A spring washer 12 is fitted on the half-tooth cover bolt 11; by fitting the spring washer 12 on the half-tooth cover bolt 11, the half-tooth cover bolt 11 is not easy to loosen after being tightened.

[0018] This utility model discloses a waterproof structure for composite shear walls. The working principle is as follows: During construction, the water-blocking partition 3 is first fixed in place. Then, composite shear wall 1 and composite shear wall 2 are joined to the left and right sides of the water-blocking partition 3 via stepped grooves 6, and the composite shear wall 1 and composite shear wall 2 are fixed in place. At this time, a T-shaped groove matching the T-shaped sealing cover 8 is formed between two adjacent sets of stepped grooves 6 of composite shear wall 1 and composite shear wall 2. Then, waterproof sealing strips 7 are glued to the two stepped surfaces of the stepped groove 6 parallel to the outer end of the limiting platform 4, and finally, the T-shaped sealing cover is installed. Plate 8 is fastened onto limiting platform 4 via slot 9, allowing T-shaped sealing cover plate 8 to fit into T-shaped groove. Finally, by passing half-tooth cover plate bolt 11 through bolt hole 10 and screwing it into mating bolt hole 5, T-shaped sealing cover plate 8 is tightly pressed into stepped groove 6, compressing waterproof sealing strip 7 to form two seals. The outer side of T-shaped sealing cover plate 8 is aligned with the outer side of composite shear wall 1 and composite shear wall 2, thus completing the waterproof seal at the joint of composite shear wall 1 and composite shear wall 2. After that, concrete can be poured into composite shear wall 1 and composite shear wall 2.

[0019] The waterproof structure of the composite shear wall of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.
