The invention belongs to the field of civil engineering, and relates to a combined crack-resistant structure of a frame structure and a filler wall interface and a construction method thereof, which are suitable for combined crack-resistant construction of the frame structure and the filler wall interface.
Background
The masonry is a brittle material, and has low strength grade, high water absorption and large shrinkage deformation. For the expansion and contraction of the masonry, different parts are different, usually two ends are large and the middle is small, and when the connection strength between the filled masonry and the concrete wall column is small and the tensile strength of a wall material is large, deformation occurs at an interface to generate an interface seam. Therefore, cracks are easy to appear at the contact part of the concrete wall column and the masonry, and the common quality common fault of the building engineering is caused.
The cracks of the masonry of the indoor filler wall with the concrete structure are mainly concentrated at the joint parts of the masonry and a concrete frame beam, a column and a wall, and belong to the field of common engineering quality problems. Because the indoor infilled wall uses light building block material more, the block wall wholeness is relatively poor, and tensile strength is lower, and is different and the coefficient of expansion is different with the material of concrete structure, and both warp and hardly coordinate unanimously, consequently under the influence of temperature, easily arouse deformation crack to lead to wall plastering layer, dope layer surface fracture.
The presence of cracks reduces the quality of the wall, such as integrity, durability and seismic performance, and the cracks in the wall can have sensory and psychological adverse effects on occupants. Particularly, as the requirements of people on the living environment and the building quality are continuously improved, the requirements on the crack control of the building wall are stricter. The existence of cracks causes adverse effects on human perception and psychology, increases the leakage risk of the outer wall surface, and becomes a very intuitive and sensitive problem for residents to judge the safety of buildings, so that high attention is paid to the problems, and a combined crack resistance and construction method of a frame structure and a filler wall interface, which can prevent common quality problems, needs to be developed urgently.
