Building assembly type steel structure building external hanging formwork

Abstract

The invention provides a building assembly type steel structure building external hanging formwork which comprises a first wallboard. A reinforcing frame is fixed to one side of the first wallboard, asecond wallboard is fixed to the side, away from the first wallboard, of the reinforcing frame, and connecting grooves are formed in the two sides, away from the reinforcing frame, of the first wallboard and the second wallboard, wherein splicing plates are arranged in the connecting grooves. According to the building assembly type steel structure building external hanging formwork, when concreteis poured, a vibrating bar penetrates through vibrating bar inserting holes and a communicating opening to enter the position between the first wallboard and the second wallboard, then the position between the first wallboard and the second wallboard is filled with the concrete, meanwhile, the vibrating bar vibrates, and the vibrating bar drives the concrete to flow, so that the concrete is compactly combined; and through the multiple vibrating bar inserting holes, the vibrating bar can be inserted between the first wallboard and the second wallboard of different layers, bubbles between the concrete are discharged, and the strength of the concrete can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to an external formwork for a prefabricated steel structure building. Background technique [0002] A building assembled from prefabricated parts on site is called a prefabricated building. When assembling a prefabricated building, it is necessary to use external formwork to pour concrete. [0003] There are some disadvantages in the use of external formwork in prefabricated steel structure buildings. The existing external formwork needs to exhaust the concrete through a vibrating rod after pouring to reduce the air bubbles between the concrete, but the concrete air bubbles deep in the external formwork cannot The sound insulation effect of the wall formed by pouring concrete through external formwork is poor, and when the formwork is spliced, most of them are fixed by steel bar welding, the splicing efficiency is low, and it is inconvenient to use, so we propose a b...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of building assembly type steel structure building external formwork, in order to solve the above background technology, there are some shortcomings in the use of the existing building assembly type steel structure building external formwork, and the existing external formwork needs to be used after pouring. Exhaust the concrete through the vibrating rod to reduce the air bubbles between the concrete, but the concrete air bubbles deep in the external formwork cannot be discharged, and the wall formed by pouring concrete through the external formwork has poor sound insulation effect, and when the formwork is spliced, most of them Fixed by steel welding, low splicing efficiency and inconvenient use
