Novel precast beam bottom form and construction method thereof

Abstract

The invention relates to a novel precast beam bottom form. The bottom form comprises steel sheet bottom forms, a moving system and a positioning piece, wherein the positioning piece is used for fixingthe steel sheet bottom forms, the moving system is arranged on the steel sheet bottom forms, so that flexible moving and splicing combining of the steel sheet bottom forms can be achieved, the construction efficiency is improved, and the mechanical machine-team and labor for changing precast specifications are saved. According to the bottom form, due to the fact that spliced bottom forms and themoving system are fixed into a movable system, moving and splicing can be conducted on the steel sheet bottom forms in the horizontal direction, the steel bar, steel sheet bottom form and concrete construction can be subjected to continuous integrated operation, and the deviation of the steel sheet bottom forms is not affected; and then, the steel sheet bottom forms are simple in structure, materials are easy to obtain, rapid splicing can be achieved through the moving system, channel steel is welded to connectors on the two sides of the spliced steel sheet bottom forms, and any two adjacent steel sheet bottom forms can be spliced into the spliced bottom forms of different specifications.

Description

technical field [0001] The invention relates to the technical field of prefabricated beam bottom formwork, in particular to a novel prefabricated beam bottom formwork and a construction method thereof. Background technique [0002] As we all know, prefabricated beams are prefabricated in factories, and then transported to the construction site to be installed and fixed according to the design requirements. [0003] However, existing problems still exist when making prefabricated beams: [0004] 1. For prefabricated beams with less used specifications and fewer production quantities, there are usually bottom forms without corresponding specifications. It is necessary to remove the original bottom form and remake the corresponding specification bottom form to meet the production. This repeated operation greatly reduces the cost of prefabricated beams. High production efficiency, but also a waste of materials and labor. [0005] 2. When the prefabricated beam factory needs to...

AI Technical Summary

Problems solved by technology

[0004] 1. For prefabricated beams with less used specifications and fewer production quantities, there are usually bottom forms without corresponding specifications. It is necessary to remove the original bottom form and remake the corresponding specification bottom form to meet the production. This repeated operation greatly reduces the cost of prefabricated beams. production efficiency, but also a waste of materials and labor

[0005] 2. When the prefabricated beam factory needs to produce prefabricated beams of various specifications, it needs to prepare bottom forms of various specifications, which requires a lot of manpower and material resources to install the bottom form, and also occupies too much land, resulting in waste and vacancy

[0006] 3. There are many specifications of prefabricated beams. If it is necessary to meet the production of prefabricated beams of various specifications, it is necessary to make bottom molds of various specifications for production, and manual maintenance is also required.
