Problems solved by technology

However, the following problems will occur when welding the water-stop sheet: 1. There will be leakage points when the full welding is not in place; 2. The welding of the water-stop sheet is a rigid connection, and there will be leakage points when deformation occurs when the force is applied
However, this method is greatly affected by rainy days. When the concrete floor is poured, the water-stop ring or the water-stop belt will often expand in advance. After the concrete solidifies, it will retract to form a cavity that cannot achieve the anti-seepage effect, which has great hidden dangers, especially the anchor rod body. Using rebar for prestressed concrete, the problem of waterproof and anti-seepage of anchor rods is more prominent

Abstract

The invention discloses a water stopper which is used for leakage prevention of the joint of an anchor rod body and a concrete bottom plate and arranged at the position, in the concrete bottom plate,of the anchor rod body. The water stopper comprises a plate body and a cylinder body penetrating through the plate body. A first through hole for the anchor rod body to penetrate through is formed inthe cylinder body. A first annular groove is formed in the inner wall of the first through hole and filled with sealant. The invention further discloses a construction method of the water stopper at the joint of the anchor rod body and the concrete bottom plate. The method includes the following steps of making a cover body, the cylinder body and the plate body penetrate through the anchor rod body, moving the cover body, the cylinder body and the plate body to a proper position of the rod body, filling a cavity between the first annular groove and the anchor rod body with the sealant, and making the cover body cover the cylinder body. The water stopper has a good leakage prevention effect.

Description

technical field [0001] The invention relates to the technical field of anti-seepage of buildings, in particular to a water stopper. Background technique [0002] When the depth of the building foundation is greater than the groundwater level, the building will float up due to the buoyancy of the groundwater. When the buoyancy is greater than the weight of the building, anti-floating anchors are usually installed under the bottom plate. [0003] For the construction process of anti-floating anchor rods, please refer to figure 1 , first drill a hole on the construction surface, put one end of the anti-floating anchor rod body 01 into the hole, then pour cement mortar or pure cement slurry, reserve a section of the anchor rod body and pour it on the concrete floor after the pullout force of the anchor rod meets the design requirements middle. Since the anti-floating anchor body 01 needs to pass through the bottom plate 02 and the waterproof layer 03 below the bottom plate 02,...
