A building assembly type steel structure building external formwork

Abstract

The invention provides an external formwork for a building assembly type steel structure building, which includes a first wall panel, a reinforcement frame is fixed on one side of the first wall panel, and a second wall panel is fixed on the side of the reinforcement frame away from the first wall panel. As for the wall panels, the first wall panel and the second wall panel are provided with connecting grooves on both sides away from the reinforcing frame, wherein a splicing plate is arranged inside the connecting grooves. In the prefabricated steel structure building external formwork, when pouring concrete, the vibrating rod penetrates through the vibrating rod socket and the communication port and enters between the first wall panel and the second wall panel, and then between the first wall panel and the second wall panel When filling concrete, the vibrating rod vibrates at the same time, and the vibrating rod drives the concrete to flow, so that the concrete is densely combined. Through multiple vibrating rod sockets, the vibrating rod can be inserted between the first wallboard and the second wallboard of different levels. The air bubbles in the concrete can be discharged, which can effectively improve the strength of the concrete.

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
