Construction Method of Filling Masonry and Frame Shear Wall to Prevent Interface Cracks

Abstract

The invention relates to an interface crack preventing structure for filling brickwork and a framework shear wall and a construction method. The interface crack preventing structure mainly comprises a floor, a brickwork wall, a ring beam, a combed joint shaped constructional column, a structure wall column, wall column preserved ribs, steel bar anchorage devices, fixing bolts, a concrete roughened surface, steel bar connecting sleeves, wall body pull ribs, constructional column longitudinal ribs, constructional column stirrups, ring beam longitudinal ribs, ring beam stirrups, concrete filling bodies, a constructional column formwork, tension screws, PVC sleeve pipes, screw steel sleeve pipes, steel wire nets, positioning blocks, plastic blocks, wall column main ribs, net hanging steel bars and pre-embedded rib sizing plates. The main construction steps include: (1) the wall column reserved ribs are pre-embedded; (2) wall column concrete is poured; (3) brickwork construction is carried out; (4) the constructional column is constructed; and (5) net hanging and plastering are carried out on a wall body. By means of the construction method, the brickwork and the wall column can be tensioned well, cracks between the brickwork and the wall column are prevented, and good economical and technological benefits are achieved.

Description

technical field [0001] The invention relates to a construction method for preventing interface cracks of filling masonry and frame shear walls. technical background [0002] Masonry itself is a brittle material with low strength grade, high water absorption and large shrinkage deformation. For the expansion and contraction of masonry, different parts are different, often the two ends are large and the middle is small. When the connection strength between the filled masonry and the concrete wall column is small and the tensile strength of the wall material is large, Deformation occurs at the interface, creating interface seams. Therefore, cracks are prone to appear in the contact position between concrete wall column and masonry, which has become a common quality problem in construction projects. [0003] The existence of cracks reduces the quality of the wall, such as integrity, durability and seismic performance, and at the same time, the cracks in the wall have adverse e...

[0003] The existence of cracks reduces the quality of the wall, such as integrity, durability and seismic performance, and at the same time, cracks in the wall have adverse effects on the occupants' perception and psychology

Common treatment methods for preventing interface cracks between masonry and structural wall columns include setting structural columns, hanging nets, etc., which can delay the occurrence of cracks to a certain extent, but from the perspective of the overall structure, the single treatment method has poor integrity. The tie strength of the wall column is insufficient, and it is easy to slowly form cracks over time, which will affect the appearance and use effect of the wall
