Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a temporary protection device for bridge construction. Background Art

[0002] Bridge construction refers to the process of building a bridge according to the design content. During the construction period, the construction area needs to be isolated from the outside world to form a closed construction space to prevent non-operating personnel from entering and reduce the probability of accidental injuries. However, there are the following disadvantages when setting up protective devices in a small construction area or for a short time:

[0003] First, the structure of the protective device is relatively fixed and needs to be fastened and assembled using bolt assemblies. However, before the bolts are fixed, the protective device can only be kept upright by itself, which increases the difficulty of fixed assembly and makes it difficult to pre-fix before fastening and assembly.

[0004] Second, the protective device is large in size, and it is difficult to improve stability by only relying on bolts to fix it to the ground during support. When adding auxiliary structures to improve stability, the auxiliary structures need to be operated separately, and the disassembly is relatively slow, making it difficult to achieve rapid disassembly and assembly. Summary of the invention

[0005] In view of this, the utility model provides a temporary protective device for bridge construction, which solves the problem that the temporary protective device is difficult to pre-fix before fastening and assembly.
