Problems solved by technology

[0003] At present, in order to improve construction efficiency in the construction industry, more and more prefabricated concrete parts are used in construction, and the existing concrete prefabricated parts can generally meet the functions of assembly and fixing when used to build the whole building, but the existing concrete prefabricated parts During the long-term use of prefabricated parts, cracks are prone to occur, which not only affects the service life of concrete prefabricated parts, but also poses certain safety hazards
[0004] The Chinese invention patent with the application number CN201710915224.9 discloses a reinforced concrete prefabricated part containing carbon fiber reinforced plastic. It has the advantages of small weight ratio, good durability, corrosion resistance, aging resistance, and high fatigue strength. It can be adhered to the concrete protective layer with the help of epoxy-based adhesive resin at the easily damaged or cracked parts of the prefabricated parts, so as to strengthen the prefabricated parts. Local shear resistance, tensile resistance and fatigue resistance can improve the ductility of components, increase the bearing capacity of components, and meet the needs of safety in use; this solution solves the problem of cracks in existing concrete prefabricated parts, and improves The safety of the use of prefabricated parts, but the function of simple transportation is not considered, which will cause inconvenience to the work of the operator
[0005] The Chinese invention patent with the application number CN201721619496.6 discloses a high-efficiency compression-resistant roof truss beam concrete prefabricated part. The solution is provided with a reinforced steel plate and a cavity, and the reinforced steel plate is interspersed with the bottom plate. A trapezoidal cavity is formed inside the reinforced steel plate. cavity, the existing double T-shaped concrete prefabricated parts have insufficient rigidity and strength, and are heavy and inconvenient to transport. The cavity can greatly reduce the weight of the prefabricated parts, reduce the labor force, and achieve the effect of facilitating transportation and movement; but this embodiment does not take into account the effect of buffering and shock absorption, thereby reducing the protection effect between the building concrete prefabricated parts

[0044] Based on the splicing and assembly type prefabricated building concrete parts provided by the first embodiment, the splicing of the main board 1 and the sub-board 11 is mainly carried out by using the threaded fitting method of the threaded rod 10 and the threaded sleeve 9, so manual work is required during assembly. Twist the threaded rod 10 between the sub-plates 11, but in actual use, this operation process will cause a gap between the main board 1 and the sub-plate 11, thereby reducing the splicing tightness and aesthetics of the concrete prefabricated parts. In order to solve this problem, Ensure that there is no gap between the main board 1 and the sub-board 11 in actual use, combined with Figure 6-8 , the spliced ​​and assembled building concrete prefabricated part also includes: the first installation block 14 is provided with feed teeth, the first installation block 14 can drive the thread teeth 10 to rotate and feed, and the middle part of the sub-plate 11 is ...

[0051]Based on the spliced ​​and assembled building concrete prefabricated parts provided by the second embodiment, the tight fixation between the components can be realized in actual use, but in special cases such as earthquakes and strong winds, the main board 1 and the sub-board 11 will follow. Shaking will eventually cause damage. Therefore, in order to solve the problem of shock absorption of the device, the original tight fixed connection method is released by means of the cooperation and linkage of various parts during the shaking process, and converted into an elastic matching method between the parts, thereby improving the device. Therefore, this kind of spliced ​​and assembled building concrete prefabricated part also includes: one side of the notch 22 is provided with a lead pendant groove 32, the top of the lead pendant groove 32 is provided with a sling 33, and the bottom of the sling 33 is provided with a Lead pendant 34, the tensile performance of sling 33 is cer...

Abstract

The invention belongs to the technical field of building accessories, and discloses a splicing assembly type building concrete prefabricated part. The splicing assembly type building concrete prefabricated part comprises a main plate, wherein fixing grooves are formed in the upper end and the lower end of one side of the main plate correspondingly, the tops of inner cavities of the fixing grooves are fixedly sleeved with fixing shafts, the outer surfaces of the fixing shafts are movably sleeved with rotating blocks, connecting devices are arranged on one sides of the rotating blocks, threaded sleeves are arranged on one sides of the connecting devices, an auxiliary plate is movably connected to one side of the main plate, mounting grooves are formed in the upper end and the lower end of one side of the auxiliary plate, and first springs are arranged on one sides of inner cavities of the mounting grooves. According to the splicing assembly type building concrete prefabricated part, rapid recovery of the connecting blocks can be achieved, threaded rods can be driven to rotate through movement of wedge-shaped blocks so as to be in threaded assembly with the threaded sleeves, a sliding rod is fixed through magnetic attraction of a first magnetic ball and a second magnetic ball, an original limiting and fixing mode can be converted into an elastic connection mode when encountering severe environments such as earthquakes, strong wind and the like, so that the damping and buffering effects are improved.

Description
