Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures, in particular to a waterproof structure for contact between an existing building and a newly built building. Background Art

[0002] During the renovation of old buildings, due to the poor bonding of new and old concrete or the thermal expansion and contraction of concrete, gaps will appear on the contact surface between the existing building and the new building, which will reduce the waterproof effect of the building. Rainwater can penetrate into the building through the gaps, which will damage and corrode the concrete structure. In addition, rainwater penetrates into the ceiling of the house and produces water stains, affecting the interior appearance. The waterproof structure is used for waterproofing the contact between the existing building and the new building. After installation, it is tightly pressed and fixed to effectively waterproof, which is convenient for effective waterproofing between buildings and improves the service life of the buildings.

[0003] A waterproof structure in contact between an existing building and a new building is disclosed in the Chinese utility model patent application disclosure CN219034141U. Although the wall of the old building is provided with a foundation reinforcement layer structure on the outside of the wall of the old building, the wall of the old building and the foundation reinforcement layer structure are evenly fixed by multiple sets of steel nail structures, and at the same time, the side of the foundation reinforcement layer structure away from the wall of the old building is fixedly connected to the concrete layer, and the side of the concrete layer away from the foundation reinforcement layer structure is coated with a first waterproof layer. In the waterproof structure in contact between the existing building and the new building, the first waterproof layer is the first waterproof structure between the wall of the new building and the wall of the old building; the second waterproof layer is the second waterproof structure between the wall of the new building and the wall of the old building. The two waterproof structures work simultaneously, and can perform water isolation between the wall of the new building and the wall of the old building, thereby improving the waterproofness between the wall of the new building and the wall of the old building. However, the waterproof structure uses multiple sets of steel nails to fix the existing buildings and the new buildings. The steel nails will become loose after being fixed for a long time, so that a gap will appear between the waterproof structure and the building, thereby failing to waterproof the building. In addition, the steel nails will deform after long-term use, and it is not convenient to replace and install them when installed inside the wall. Utility Model Content

[0004] The utility model aims to provide a waterproof structure for contact between an existing building and a new building, so as to solve the problems raised by the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Waterproof structures where existing buildings come into contact with new buildings, including:

[0007] An old building body, a new building body is arranged on one side of the old building body, a waterproof structure is arranged at the top connection between the old building body and the new building body, a top plate is fixedly connected to the top of the waterproof structure, threaded holes are arranged at both ends of the upper surface of the top plate, second bolts are penetrated through the threaded holes and the interior of the waterproof structure, and the top plate, the new building body and the old building body are tightly fixed by the second bolts, a cavity is arranged inside the waterproof structure, a support block is arranged at the bottom of the cavity, a clamping block is slidably connected to the top of the support block, a trapezoidal slider is arranged on the side of the clamping block, a support column is arranged at the bottom of the trapezoidal slider, and a spring is arranged on the outer surface of the support column.

[0008] Preferably, grooves are provided on the inner sides of the old building body and the new building body, and an epoxy resin layer is provided at the connection between the old building body, the new building body and the waterproof structure.

[0009] Preferably, an elastic sheet is provided at the middle position of the top of the top plate, a first bolt penetrates the elastic sheet and the interior of the top plate, and the first bolt penetrates the waterproof structure and extends to the interior.

[0010] Preferably, movable holes are provided on both sides of the waterproof structure, and the movable holes are communicated with the groove.

[0011] Preferably, the first bolt is fixedly connected to the top of the trapezoidal sliding block, and bumps are arranged on both sides of the trapezoidal sliding block.

[0012] Preferably, the trapezoidal slider is slidably connected to the side of the clamping block, and there are two groups of the clamping blocks.

[0013] Preferably, the clamping block is slidably connected to the top of the supporting block, and the clamping block matches the groove.

[0014] Preferably, the bottom of the trapezoidal sliding block is fixedly connected to the supporting column, and the supporting column penetrates the waterproof structure and extends to the outside.

[0015] Preferably, the spring is provided on the outer surface of the support column, and the tail end of the spring is fixed inside the waterproof structure.

[0016] Preferably, the old building body, the new building body and the waterproof structure are more firmly fixed by the provision of the epoxy resin layer.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model uses an elastic sheet designed on the surface of the top plate and a spring and a clamping block designed inside the waterproof structure to avoid the bottom end of the waterproof structure from being unable to be pressed and fixed during installation, resulting in the waterproof structure being not fastened to the building and being easy to loosen. The waterproof structure is placed at the connection between the first building body and the second building body, and the first bolt is rotated. The first bolt drives the trapezoidal sliding block to move downward, and the trapezoidal sliding block drives the clamping blocks at both ends to move toward both ends along the sliding groove on the top of the supporting block, so that the clamping blocks are fixed to the inside of the groove through the moving hole, thereby strengthening the fastening of the waterproof structure to the building body. At the same time, the first bolt and the second bolt are arranged on the top plate at the connection between the old building body and the new building body, thereby avoiding the situation where the bolts are damaged and difficult to install and repair.
