Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall construction, in particular to a concrete exterior wall waterproof structure. Background Art

[0002] External wall waterproofing is a sub-project to ensure that the structure of a building (structure) is not invaded by water and the internal space is not harmed by water. External wall waterproofing projects involve many external wall structures such as the basement external wall and the housing external wall of the building (structure). Its function is to prevent the leakage of rainwater, domestic water and groundwater erosion within the design durability of the building or structure, ensure that the building structure and internal space are not damaged, and provide people with a comfortable and safe living environment.

[0003] During the construction of existing basement concrete exterior walls, the formwork is usually supported at right angles, so that the corners of the concrete exterior wall structure are right angles, causing the laid waterproof membrane to be excessively bent and damaged, affecting the waterproof effect.

[0004] However, some existing chamfering treatments are mostly used for external corners, and no chamfering treatment is performed on internal corners, which makes it easy for waterproof membranes to bend when laid at internal corners. At the same time, the existing waterproof membranes are mostly laid by laying pre-cut waterproof membranes flat on the wall, gradually pasting them from bottom to top, and using a scraper to compact the membranes and the wall and remove air. However, such laying requires continuous scraping of air, and at the same time, it is easy for the roots to bulge, which affects the laying effect of the membranes.

[0005] Therefore, there is an urgent need for a concrete exterior wall waterproof structure that can facilitate the laying of waterproof membranes and improve the waterproof effect. Utility Model Content

[0006] The utility model aims to provide a concrete exterior wall waterproof structure to solve the problems existing in the background technology.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] A concrete exterior wall waterproof structure comprises, from top to bottom, a top plate, an exterior wall and a raft plate, wherein a first chamfer is arranged at the connection between the top plate and the exterior wall, a second chamfer is arranged at the connection between the exterior wall and the raft plate, a third chamfer is arranged at the connection between the two exterior walls facing inward, and a fourth chamfer is arranged at the connection between the two exterior walls facing outward, wherein the first chamfer, the second chamfer, the third chamfer and the fourth chamfer are all located on the water-facing side; waterproof coiled materials are arranged outside the top plate and the exterior wall, and metal pressure strips and iron nails are arranged on the waterproof coiled materials.

[0009] Furthermore, the metal pressure strip is located on the top plate, the iron nail passes through the metal pressure strip and is fixed to the top plate, and the waterproof membrane is fixed to the top plate through the metal pressure strip and the iron nail.

[0010] Furthermore, two adjacent waterproof membranes are stacked up and down, and the two adjacent waterproof membranes are fixedly connected by a seam sealant.

[0011] Furthermore, a waterproof sealant is provided at the connection between the iron nail and the metal strip.

[0012] Furthermore, the first chamfer, the second chamfer, the third chamfer and the fourth chamfer are oblique chamfers or arc chamfers.

[0013] The beneficial effects of the utility model are:

[0014] 1) The four chamfers can prevent the joints of the exterior wall from being bent and damaged when laying waterproof membranes in the later stage, thereby improving the quality of waterproof construction.

[0015] 2) The waterproof membrane is constructed vertically. The upper part of the waterproof membrane is fixed with metal strips and nails, so that the lower waterproof membrane falls naturally due to gravity, effectively reducing the root bulging problem caused by the traditional paving method and reducing the labor intensity of manual upward construction.
