Abstract

The invention discloses a bolt pin-type crossed tenon tooth precast concrete unit and a preparation method thereof. The bolt pin-type crossed tenon tooth precast concrete unit comprises a first splicing part, a second splicing part, segregation boards and shearing force locking bolt pins. Tenon teeth and mortises are arranged at the splicing ends of the first splicing part and the second splicing part at intervals. Each tenon tooth is a prism with the trapezoidal cross section. The segregation boards are provided with folding structures consistent with the tenon teeth and the mortises of the second splicing part. Bolt pin holes are formed in the positions, corresponding to bolt pin mounting cavities of the second splicing part, of the segregation boards. The shearing force locking bolt pins are mounted in the first bolt pin mounting cavities and the second bolt pin mounting cavities in a penetrating mode. The bolt pin-type crossed tenon tooth precast concrete unit is simple in structure. The precision requirement for formworks is low at the prefabrication stage. After prefabrication is completed, precision of joint cracks between precast parts is high, and no subsequent repairing treatment is required after splicing is completed. In addition, the highest splicing speed can be realized under the condition of not decreasing the cross section of the precast concrete unit.

Description

technical field [0001] The invention relates to a pin-bolt type cross tenon tooth prefabricated concrete component and a preparation method of the pin bolt type cross tenon tooth prefabricated concrete component. Background technique [0002] During the construction of cast-in-place reinforced concrete structures, there are many on-site fabrications and wet operations, and there are a large number of intermediate links such as formwork projects and scaffolding projects, which waste resources and pollute the environment; the quality of employees and the environment of the construction site have a great impact on the construction quality, bringing Issues of building performance, quality and durability. To change the status quo of cast-in-place reinforced concrete structures, prefabricated concrete structures should be vigorously developed. The main structural components of prefabricated concrete structures are manufactured in factories, which have high production efficiency a...
