Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a bridge construction protection device to solve the problem that in the prior art, due to the fact that the fence of the bridge bends from the lower end to the upper end, the positions between the upper and lower ends protrude differently, and in the construction area During the protection, the contact area between the side and the fence will be empty, resulting in a gap in the protection of the side area, which makes it incomplete for the protection of the staff and reduces the safety problem during construction.

Abstract

The invention discloses a bridge construction protection device, which comprises a fixed frame, a bottom plate, a side protection structure, a horizontal frame, and a protective net. Between the side protection structures, the protection net is installed on the inner side of the horizontal frame. The side protection structure includes a fixed frame, a fixed protection net and a movable protection net. In the present invention, a movable protective net is arranged outside the fixed protective net to protect the contact area between the side and the fence, reduce the gap of protection, provide more comprehensive protection during construction, and improve the safety of construction; The movable frame fully restricts the part with the fence, thereby preventing the existence of gaps, ensuring the comprehensiveness of construction protection, and thus improving the safety of construction.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a bridge construction protection device. Background technique [0002] In the bridge construction, it includes the construction of the bridge pier and the construction of the bridge deck. In the construction of the bridge deck, the fence of the bridge deck also needs to be constructed. The bridge deck fence of the expressway is all made of concrete. During demoulding and overhaul, it is necessary to work on the outside of the fence, and because the bridge is relatively high in order to ensure the safety of the construction personnel, it needs to be protected, so bridge construction protection devices are needed, but the existing technology has the following deficiencies: [0003] Since the fence of the bridge bends and converges from the lower end to the upper end, the positions of the upper and lower ends protrude differently. When protecting the area, the contact ...
