Prefabricated road board connected with bolt with one end bent back as well as production method and connection technologyof prefabricated road board

Abstract

The invention provides a prefabricated road board connected with a bolt with one end bent back as well as a production method and a connection technology of the prefabricated road board. The prefabricated road board comprises a road board main body, wherein the top of the road board main body is provided with a horseshoe groove, the interior of the road board main body is provided with an arc-shaped hole, and construction specifically comprises the following steps that the construction procedure that reinforcing meshes are tied manually and then the reinforcing meshes are integrally carried into a mold is adopted; template construction is conducted, side forms are assembled and then placed on a special steel platform, and the situation that a demolding agent pollutes prefabricated board reinforcing steel bars in a process of entering a mold needs to be avoided; pre-buried pieces are mounted, the horseshoe groove needs to be pre-buried before pouring of the prefabricated road board, andthe horseshoe groove is fixed to a limiting frame through a bolt; convex and concave steel plates are pre-buried at four sides of a prefabricated form respectively; concrete construction is conducted, manual vibration is conducted, and the concrete is vibrated compactly and uniformly; and concrete curing is conducted, the formed prefabricated road board is placed into a steam curing tank by usingan elevator to be subjected to steam curing. The prefabricated road board has the beneficial effects that firstly, the cost is low; secondly, the safety coefficient is high; thirdly, the constructionefficiency is high; fourthly, the construction quality is guaranteed; and fifthly, the pollution to the environment is less.

Description

Technical field [0001] The invention relates to the technical field of prefabricated road slabs, in particular to a prefabricated road slab connected by elbow bolts, and a manufacturing method and connection process thereof. Background technique [0002] At present, temporary roads mostly adopt the traditional method of casting concrete pavement, which takes a long time to construct and consumes a lot of manpower; transportation of materials to the construction site during construction and the passage of other vehicles will adversely affect the construction period . Not only that, after the temporary roads are used up, the pavement of the site needs to be destroyed, which not only requires a lot of manpower, but also causes materials and the environment that do not meet the requirements of green construction and sustainable development. In addition, the traditional operation method is open-air operation, and the procedures are overlapped, and there are certain safety risks. Sum...

AI Technical Summary

Problems solved by technology

[0002] At present, the traditional concrete cast-in-place pavement technology is mostly used for temporary roads, which takes a long time to construct and consumes a lot of manpower; during the construction period, the transportation of materials to the construction site and the passage of other vehicles will bring adverse effects on the construction period

Not only that, after the temporary road is used up, the road surface of the site needs to be demolished, which not only requires a lot of manpower, but also causes damage to materials and the environment, which does not meet the requirements of green construction and sustainable development

In addition, the traditional operation method is open-air operation, and the process is crossed, so there are certain safety hazards
