Embodiment Construction

[0024] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0025] like figure 1 and 2 As shown, a waterproof structure at the root of an exterior wall of a building includes a structural board 1, a longitudinal wall 2 perpendicular to the structural board 1, and an expansion waterstop 4 embedded at the bottom of the longitudinal wall 2, wherein the longitudinal wall is 2 can be a reverse sill or a shear wall, the bottom of the longitudinal wall 2 is provided with a steel frame 3, the expansion water stop 4 is vertically embedded on the midline of the bottom of the longitudinal wall 2, and the lower part of the expansion water stop 4 crosses over. The thickness direction of the structural plate 1 is fixed on the steel frame 3. In this embodiment, the length of the expansion waterstop 4 in the vertical direction is 300mm, and the length of its upper part extending into the longitudinal wall 2 is 150mm. This d...

Abstract

The invention discloses a building outer wall root waterproof structure which comprises a structural plate and a longitudinal wall body perpendicular to the structural plate, a steel reinforcement framework is arranged at the bottom of the longitudinal wall body, and the building outer wall root waterproof structure is characterized in that an expansion water stop belt is embedded in the bottom of the longitudinal wall body and is vertically arranged in the height direction of the longitudinal wall body; the lower portion of the expansion water stop belt crosses the thickness direction of the structural plate and is fixedly connected to the steel reinforcement framework. The method has the beneficial effects that the expansion water-stop belt is vertically arranged at the bottom of the longitudinal wall body, so that seepage of accumulated water on the outer wall can be effectively prevented, and the hidden danger of seepage of the root of the wall body is fundamentally solved; due to the structural design of the special structure of the lower portion of the expansion water-stop belt, the expansion water-stop belt can be fixedly installed on the steel reinforcement framework conveniently and rapidly, concrete pouring can be conducted without additional formwork erecting, and the technical advantage of convenient construction is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a waterproof structure at the root of an outer wall of a building. Background technique [0002] The exterior wall of the building has many important functions such as exterior decoration, thermal insulation, waterproof and windproof, structural load-bearing, etc., and is an important part of the construction project. If the exterior wall of the building leaks, the infiltration of rainwater cannot be effectively prevented, which will not only directly affect people's quality of life, but also seriously affect the service life of the building. [0003] Nowadays, the leakage of building exterior wall is a frequent quality problem, among which the leakage at the root of the exterior wall occupies a considerable proportion. In the prior art, the conventional root waterproofing measure is to pour a concrete back sill with a wall thickness of 200mm in the water-prone ...
