Embodiment Construction
[0052] Examples see figure 1 , figure 2 As shown, this cast-in-place integral concrete frame filled wall system includes a rectangular frame formed by frame beams 1 and frame columns 8 and a cast-in-place filled wall 2 poured in the rectangular frame. The cast-in-place filled wall 2 is Reinforced concrete wall, the internal reinforcement skeleton includes two layers of steel mesh sheets arranged in parallel and spaced apart and tie bars 4 connected between the two layers of steel mesh sheets, and the distance between the two layers of steel mesh sheets is smaller than that of the cast-in-place filling wall 2 The thickness of the reinforcement mesh sheet is in the form of a rhombus grid, which is formed by the double oblique crossing of the tie bars connected between the frame beam and the frame column, and the tie bars 3 are obliquely connected between the frame beam 1 and the frame column. Between the frame columns 8, two of the tie bars are cross-connected on the diagonal ...

The invention relates to a cast-in-situ integral type concrete frame infilled wall system and a construction method thereof. A cast-in-situ infilled wall is a steel reinforced concrete wall, and a steel reinforcement framework in the cast-in-situ infilled wall comprises two layers of steel reinforcement meshes arranged in parallel in a spaced mode and tie pieces connected between the two layers of steel reinforcement meshes. The distance between the two layers of steel reinforcement meshes is smaller than the thickness of the cast-in-situ infilled wall. Each steel reinforcement mesh is in a rhombic grid shape and is formed by crossing tie bars connected between frame beams and frame posts in double oblique directions, wherein two of the tie bars are connected to the diagonal lines of a rectangular frame. One-piece casting is adopted for the wall, the development of cracks of the infilled wall is effectively restrained by oblique crossing of the oblique tie bars in concrete, the tying effect of the tie bars is enhanced, and the maximum fixing function of the tie bars is achieved by connecting the tie bars with the adjacent beams and posts. According to the construction method, a formwork with trenches is adopted, fast pouring of the concrete of the frame infilled wall is realized, and thus one-piece casting construction of the frame infilled wall is completed with high efficiency and high quality in a time and labor saving mode.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a filling wall structure system and a construction method thereof. Background technique [0002] At present, some small hollow blocks or perforated bricks are usually used for building frame-filled walls, which are connected with the main structure through a certain number of tension bars, but this structure has certain defects. [0003] In terms of structural mechanical performance, due to the quality of the masonry, the overall performance of the infill wall is poor. Under the action of earthquakes, the infill wall is prone to slip damage of the masonry mortar layer. At the same time, the masonry mortar is prone to shrinkage during the air-drying process, causing the filling wall to settle and separate from the frame beam, resulting in cracks. [0004] From the perspective of construction, the masonry of blocks or bricks is time-consuming and laborious, which increases ...
