Embodiment Construction

[0041] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0042] refer to figure 1 The method for preventing cracks at the joint between the concrete structure and the backfill wall of the present invention mainly includes three steps: masonry construction of the fill wall, plastering construction of the fill wall, and construction of anti-crack tape on the joint. Each step is described in detail below.

[0043] 1. Masonry construction of infill wall

[0044] 1. Interface processing

[0045] Before masonry, brush the concrete interface of the connection part with cement mortar glue, and the thickness of the cement mortar glue brush is ≤3.0mm.

[0046] The composition and weight ratio of cement mortar glue are:

[0047] 901 construction glue: cement: sand = 1:1.5:1.

[0048] It has been verified that the cement mortar glue of this composition has high bonding strength.

[0049] 2. Pre-plast...

Abstract

The invention discloses a method of preventing a connecting part between a concrete structure and a rear filling wall from being cracked. The method is characterized by comprising the following steps: masonry construction of filling wall, plasterering construction of filling wall and construction of pasting anti-cracked woven belt outside the connecting part, wherein the process of the construction of pasting anti-cracked woven belt outside the connecting part comprises grinding and cleaning up the surface of a substrate, snapping a line on the surface of the substrate to determine the gluing scope of the woven belt, coating primer in the gluing scope, gluing the anti-crack woven belt and pressurizing the woven belt to be fully soaked by a scrapping plate, and coarsening or protecting the surface of the anti-crack woven belt after colloid is dried or solidified. The method provided by the invention has the beneficial effects of ensuring that the filling wall and a primary concrete structure are built and squeezed densely by improving and promoting an existing traditional masonry construction process; meanwhile, furthermore anti-cracking or effectively covering can be realized by adopting an effective external enhanced cloth through the combined action of two defense lines, the overall process is simple and the idealistic anti-cracking effect can be realized.

Description

technical field [0001] The invention relates to a method for preventing cracks, in particular to a method for preventing cracks at the joint between a concrete structure and a backfilling wall, and belongs to the technical field of construction. Background technique [0002] General frame structure, shear wall structure and frame shear wall structure are collectively referred to as reinforced concrete structure. In reinforced concrete structures, some shear wall building openings (such as door and window openings) and earthquake-resistant openings are usually partially or completely built with back-built filling walls, and some frame or frame-shear structures are usually separated by back-built filling walls. Building space to meet the owner's use requirements. [0003] According to the revised "Code for Design of Masonry", the connection methods between the back-filling wall and the concrete structure can be divided into the following two types: [0004] The first is to d...
