Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated road slabs, and particularly to a dust-free construction site assembled temporary PC road slab. Background Art

[0002] Currently, there is little research on prefabricated temporary sites and construction access roads at home and abroad. Some researchers still focus on prefabricated concrete road surfaces in this area, and most of them are still in the research stage. This is mainly due to problems such as prefabrication and transportation of prefabricated road slabs, which result in high costs, inconvenient disassembly, transportation, and low reuse rates. Therefore, cast-in-place concrete (or reinforced concrete) is mostly used as the temporary construction site or access road at domestic construction sites. Cast-in-place sites have disadvantages such as long construction periods, low work efficiency, high costs, and difficult maintenance. Only a very small part of the existing sites and temporary access roads can be used as permanent sites in the form of "combining temporary and permanent", and most of them still need to be demolished and cleared later and then reinstalled for permanent sites, which seriously affects the project progress and is not conducive to cost control. The on-site sites are often damaged during use, and it is difficult to repair in the form of reinforced concrete. Summary of the Utility Model

[0003] The present invention discloses a dust-free construction site assembled temporary PC road slab, aiming to solve the problems in the prior art that "cast-in-place concrete (or reinforced concrete) is used as the temporary construction site or access road, and the cast-in-place site has a long construction period, low work efficiency, high costs, and difficult maintenance".

[0004] To achieve the above object, the technical solution of the present invention is as follows:

A second hook-shaped structure inclined outward is provided at the bottom of the second elastic plate. The second elastic plate is closely attached to the front and rear inner walls of the connecting box body. The second hook-shaped structure is clamped with the corresponding small cover plate connecting hole. Fifth plate bodies are respectively provided at the left and right ends of the lower surface of the fourth plate body. Sixth plate bodies are respectively provided at the front and rear ends between the two fifth plate bodies.

[0010] Preferably, the plate connecting piece includes a rod body. A conical structure is provided at one end of the rod body. First clamping blocks are symmetrically arranged on the outer surface of the rod body behind the conical structure. Second clamping blocks are symmetrically arranged at the rear end of the rod body.
