Basement floor drain board and construction process thereof

Abstract

The invention discloses a basement floor drain board and a construction process thereof. The basement floor drain board comprises a drain board body, a plurality of supporting frustums and an overheadprevention device, wherein the support frustums are distributed and fixed to the surface of the drain board body in a rectangular array mode; a plurality of mounting holes are formed in the position,corresponding to the supporting frustums, of the drain board body; and the overhead prevention device is installed outside the supporting frustums. A traditional drain board frustum-shaped support ischanged into prismatic support so as to increase the contact surface. The strength of the drain board is improved, and the overhead prevention device sleeves the outer side of the prismatic support which may be overhead, so that the overhead phenomenon is greatly reduced, the strength of the drain board is improved, and steel bar binding and concrete surface casting in the later period are more stable.

Description

technical field [0001] The invention relates to the technical field of drainage boards, in particular to a basement floor drainage board and a construction process thereof. Background technique [0002] The basement is an important part of most industrial and civil buildings. With the rapid development of the national economy, urban land resources are constantly decreasing, and more and more industrial and civil buildings are expanding to the underground space. At the same time, the leakage of the basement floor Water problems are also becoming increasingly prominent, especially in Ningbo, which is a coastal city with many inland rivers and high groundwater levels, so the waterproof requirements for basements are also high. In the past, the basement of the project used the self-waterproofing of the floor concrete combined with the membrane or the waterproof layer of the film to achieve the purpose of preventing leakage. However, due to the existence of capillary pores in the...

Problems solved by technology

[0003] All the fulcrums of the existing drainage board must touch the ground, and the force is balanced, so that the drainage board will not be lifted due to the unevenness of the base layer, which will cause the surface layer to be damaged due to uneven force

The hole position of the traditional high-impact polystyrene water filter plate is circular, and the contact area between the bottom of each fulcrum and the ground is small. During the laying process, it is easy to produce overhead phenomena, which will affect the strength of the concrete floor in the later stage, and the specifications of the general drainage plate Most of them are strip-shaped, and they are rolled into bundles during packaging and transportation. In this way, the drainage boards transported to the construction site will be curled due to the reason of bundling after unbundling, which is not smooth. At the same time, the ground may be uneven. It will increase the probability of the fulcrum overhead and affect the strength of the concrete floor in the later stage. We propose a basement floor drainage board and its construction technology
