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 for preventing cracks at the connection part between a concrete structure and a post-built filling wall, which is characterized in that it comprises the following steps: construction of filling wall masonry construction-filling wall plastering construction-construction of anti-cracking cloth belt on the connection part, Among them, the construction process of pasting the anti-cracking cloth tape on the connection part is as follows: grinding and cleaning the surface of the substrate, stretching the thread on the surface of the substrate to determine the pasting range of the cloth tape, brushing the primer within the pasting range, and pasting the anti-cracking cloth tape And use the scraper to properly pressurize the cloth tape to fully moisten it. After the colloid is dried or cured, the surface of the anti-crack cloth tape is roughened or protected. The invention is beneficial in that: by improving and improving the current traditional masonry construction technology, it is ensured that the filling wall and the original concrete structure are tightly packed, and at the same time, the effective external reinforcement tape is used to further resist cracking or effectively cover, and the second road The defense lines work together, the whole process is simple, and it has an ideal anti-crack effect.

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. Architectural 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...
