Fastening bolt for shear wall formwork

Abstract

The invention relates to a fastening bolt for a shear wall formwork. The fastening bolt comprises a pre-buried fastening bolt, a nut, a reinforcing connecting rod and a clamp shaped like a Chinese character 'shan'. The pre-buried fastening bolt comprises a head part and a rod body. Outer threads are arranged at the lower end of the rod body. Inner threads are arranged on the nut. The inner threads are matched with the outer threads at the lower end of the rod body. A nut sleeve pipe is arranged on the outer portion of the nut. The two ends of the reinforcing connecting rod are provided with outer threads. The inner threads of the nut and the outer threads of the reinforcing connecting rod are matched. A thread hole is formed in the middle of the clamp shaped like the Chinese character 'shan'. The size of the thread hole is matched with the outer threads of the reinforcing connecting rod. The fastening bolt has the advantages that the pre-buried fastening bolt is used on an outer wall construction seam part, cost is saved, the common quality problems that outer wall connection portions are not smooth, and slurry leakage happens are effectively avoided, the phenomenon that a support is not arranged on the outer wall formwork during reinforcing through a bottom thread hole is avoided, formwork reinforcing time is saved, and operation is safe and reliable.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a fastening bolt for a shear wall formwork. Background technique [0002] High-rise buildings continue to develop with the deepening of urbanization. As the main structural form of high-rise buildings, shear walls have been widely used in the structural design of high-rise buildings due to their good seismic and wind resistance performance. From the perspective of design, it is the development direction of future building structure design to achieve flexible structural layout, low cost and good economy of high-rise buildings, and to pursue the benign combination of style innovation, functional requirements and structural safety. play a pivotal role. [0003] However, in the actual construction process, the quality of concrete molding is not high due to factors such as workers' operating level, technical errors, and increased formwork turnover times, especially in the constr...

Problems solved by technology

[0003] However, in the actual construction process, the quality of concrete molding is not high due to factors such as workers' operating level, technical errors, and increased formwork turnover times, especially in the construction joints of the outer wall of the shear wall, where grout, rotten roots, etc. are most likely to occur. A series of quality problems such as slurry leakage and wrong platform

The above problems have a great influence on the overall performance of the structure and the decoration of the exterior wall in the later stage, which increases the cost of concrete repair in the later stage; especially the exterior wall of this project is mainly painted wall surface, which has a greater impact on the quality of the concrete forming of the shear wall exterior wall Therefore, how to ensure the forming quality of the construction joints of the exterior wall has become the primary consideration
