Abstract
Description
Technical Field
[0001] The utility model relates to an anti-displacement fixing device for masonry tie bar embedded parts, belonging to the technical field of construction. Background Art
[0002] With the continuous development of the construction industry, infill wall masonry has been widely used in construction projects. In order to meet the requirements of earthquake fortification, ensure the construction quality of infill wall masonry, prevent cracking, and improve the safety of building structures, it is usually necessary to set tie bars in the infill wall masonry to ensure that the infill wall and the main structure are reliably tied. The construction quality of the tie bars will directly affect the construction quality of the infill wall masonry. At present, the construction of tie bars usually adopts the embedded reinforcement construction technology. The embedded reinforcement construction technology is a post-anchoring technology that drills holes, injects glue, and implants tie bars on the concrete according to the block module after the main structure is completed. Although this technology has accurate positioning and convenient construction, it is very easy to cause the embedded steel bars to loosen and fail the pull-out test due to reasons such as non-standard construction, which seriously affects the structural safety of the project, reduces the earthquake resistance of the project, and leaves quality risks.
[0003] In order to make up for the technical defects of rebar planting, the pre-embedded construction technology of tie bars is adopted. The pre-embedded construction technology of tie bars is divided into two types: traditional pre-embedded construction technology of tie bars and pre-embedded construction technology of embedded parts. The traditional pre-embedded construction technology of tie bars requires drilling holes and inserting bars on the template according to the block module before pouring the main concrete to embed the tie bars in place. The tie bars are exposed outside the main structure for a long time, resulting in damage to the template when removing the template, reducing the turnover of the template, increasing the cost, and the position of the pre-embedded tie bars during masonry construction may not be completely consistent with the masonry module. The pre-embedded construction technology of embedded parts requires fixing the embedded parts on the main structure steel bars according to the block module before pouring the main concrete, and then welding the tie bars to the embedded parts during masonry construction. However, during the concrete pouring process, it is easy to shift under the action of the vibration load of the vibrating rod and the impact load of the concrete, resulting in inaccurate position of the embedded parts, which are completely immersed in the concrete. During the welding construction of the tie bars, the chiseling is too deep or the area is too large, which affects the protective layer of the main structure steel bars and weakens the cross-sectional size of the concrete structure.
