Prefabricated concrete face plate, connecting structure of prefabricated concrete face plate and mounting method of prefabricated concrete face plate

Abstract

The invention provides a prefabricated concrete panel which comprises a prefabricated concrete panel body, embedded rods and reserved grooves are arranged on the two side plate edges of the prefabricated concrete panel body in a staggered mode, and the embedded rods and the reserved grooves are used for splicing and connecting the prefabricated concrete panel. The invention provides a connecting structure of precast concrete panels, which comprises a plurality of precast concrete panels which are spliced and connected. The invention further provides a mounting method of the precast concrete panel. According to the precast concrete pavement slab connecting structure based on staggered pull rod connection, the problems that due to the fact that a reserved groove is too close to a single-side slab edge, the strength of the slab edge is seriously weakened, and the force transmission effect is affected are solved; and secondly, through staggered lap joint, force transmission between the plates can be more balanced, and the integrity between the plates is higher.

Description

technical field [0001] The invention relates to the field of fabricated cement concrete, in particular to a prefabricated concrete panel, a connection structure and an installation method of the prefabricated concrete panel. Background technique [0002] With the rapid development of my country's infrastructure construction. In terms of airports, it is usually necessary to quickly repair a large area of ​​structure under the condition of non-stop. Prefabricated cement concrete is the best choice. In addition, considering that the number and density of domestic airports are quite different from those of foreign countries, new airports will be directly used in the future. Prefabricated cement concrete paving methods and the establishment of a set of mature technologies are also the general trend. Speed, convenient maintenance and repeated use are the core advantages of prefabricated cement concrete; in roads, container freight yards, etc., more and more prefabricated concrete ...

AI Technical Summary

Problems solved by technology

[0003] The existing prefabricated concrete panel connection structures using tie rods and slots on the market either only have tie rods on one side or only slots on one side, which is prone to too many edge grooves, which will lead to excessive weakening of the edge strength and affect its use effect ;Secondly, the occlusal integrity of unilateral grooves or unilateral tie rods is poor, which is prone to local damage on one side and affects the use of the board; moreover, the reinforcement tie rods on one side are arranged densely, and the number of grooves on one side is denser , the center of gravity shifts greatly during hoisting, and the hoisting construction is more complicated
