Construction method of waterproof leaking stoppage structure of building seam

Abstract

The invention discloses a waterproof leaking stoppage structure of a building seam and a construction method. The waterproof leaking stoppage structure of the building seam, disclosed by the invention, comprises a building seam, structural bodies located at two sides of the building seam and a water stop. A water stopping surface of each structural body includes a groove which is parallel with the building seam; the two sides of the water stop include flangings which are inserted into the grooves; and the grooves are filled with a binder which is used for fixing the flangings of the water stop into the grooves. The waterproof leaking stoppage structure disclosed by the invention has the advantages of good waterproof performance, low working hour consumption, low usage of the binder, simple construction process as well as small exposed area of the binder during the construction and is hardly polluted.

Description

[technical field] [0001] The invention relates to building structures, in particular to a construction joint waterproof and leak-stopping structure and construction method. [Background technique] [0002] Construction joints include construction joints and deformation joints, and the interval between construction joints is 0. Deformation joints include expansion joints, settlement joints, and seismic joints. Usually, the spacing of deformation joints is 20-300mm. [0003] In order to prevent external water from seeping into the building joints, the building joints need to be waterproofed and plugged. [0004] The current waterproof and plugging structure of building deformation joints using epoxy resin adhesive is as follows: figure 1 As shown, it includes a deformation joint 1 , a seam-side structure 2 , a waterstop 3 , an adhesive layer formed by epoxy resin adhesive, and an anchor point 4 . The waterproof structure and construction technology of the current building jo...

Problems solved by technology

[0007] 2) It takes several hours for the adhesive to solidify to form the initial bonding strength. During this period, the contact pressure between the coil waterstop, the concrete substrate and the adhesive needs to be maintained, otherwise it is easy to form a virtual bond, which requires a lot of labor. Time, can not be "wait for it", not only a waste of labor costs, but also can not meet the requirements of the construction period

[0008] 3. The epoxy resin adhesive is exposed, which is easy to pollute the environment and is not conducive to civilized construction

[0009] 4. The amount of epoxy resin adhesive is large
