Finalized prefabricated type reinforced concrete support cover plate and construction method

Abstract

The invention discloses a finalized prefabricated type reinforced concrete support cover plate and a construction method, and belongs to the technical field of construction engineering. The finalizedprefabricated type reinforced concrete support cover plate is used for being mounted at the collision position of a support stack bridge and a collision component in a cast-in-place reinforced concrete support structure, an L-type rabbet is manufactured at the collision position of the support stack bridge, the cover plate is prefabricated in advance, and the cover plate is hoisted to the L-type rabbet after the support stack bridge is maintained. The finalized prefabricated type reinforced concrete support cover plate is prefabricated in advance, the number of field construction staff is greatly reduced, the operation time is shortened, and time and labor are saved. When the structure is provided with components like steel stand columns which collide with the stack bridge, particular holing is not needed, the construction demands are met, and safe and civilized construction control is facilitated. Construction is easy and convenient, and the cover plate is directly hoisted to the corresponding position.

Description

technical field [0001] The invention relates to a stereotyped prefabricated reinforced concrete support cover plate and a construction method, belonging to the technical field of construction engineering. Background technique [0002] Now the overall cast-in-place reinforced concrete support system is widely used in various foundation pit projects. It is poured on site and has various forms, such as opposite braces, side trusses, and ring beams combined with side trusses. Generally, multiple supports and auxiliary components form an overall force-bearing system, which has many advantages such as high overall rigidity, small deformation, safety, reliability, and convenient construction, so it is widely used in engineering practice. [0003] However, the production site of the cast-in-place reinforced concrete support needs a lot of manpower and material resources, the support casting and curing time is long, and the enclosure structure is in an unsupported exposed state for a...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem in the prior art that when there are components that collide with the trestle slab, such as steel columns, it is necessary to open holes on the cast-in-place reinforced concrete trestle slab, which is time-consuming and laborious and is not conducive to safe and civilized construction, a stereotyped prefabrication method was invented. The prefabricated reinforced concrete support cover plate and its construction method have the advantages of saving time and effort, and are conducive to safe and civilized construction control
