Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a protective device for road and bridge construction. Background Technology

[0002] During road and bridge construction, protective devices are usually required to be installed in the construction area to ensure the safety of pedestrians and vehicles around the construction area and to prevent the impact of flying gravel and dust on the surrounding environment and people.

[0003] Currently, existing road and bridge construction safety devices are mostly simple, spliced ​​guardrails with a relatively simple structure, only capable of providing basic isolation and blocking functions. In actual use, gaps often exist between the guardrails, allowing large amounts of dust generated during construction to easily spread into the surrounding environment, polluting the air and potentially affecting the normal lives of nearby residents and the health of passersby. At the same time, flying debris during construction can easily penetrate the gaps in the guardrails, posing safety hazards to pedestrians and vehicles, resulting in insufficient safety protection. Summary of the Invention

[0004] The purpose of this utility model is to provide a road and bridge construction protection device in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A road and bridge construction safety device includes columns and hanging rings symmetrically arranged on the columns, and further includes: A guardrail, wherein the guardrail is installed between posts by hooks, and the hooks are inserted into hanging rings; A dustproof net is installed on the rear end face of the guardrail using fasteners.

[0006] Preferably, the fastener includes an annular frame disposed on the rear end face of the guardrail, and a pressure block is provided inside the annular frame.

[0007] Preferably, the pressure block is provided with symmetrical retaining strips, and the inner wall of the annular frame is provided with retaining grooves to match the retaining strips.

[0008] Preferably, a circular cavity is formed on the bottom surface of the hook, and a locking pin is provided inside the circular cavity.

[0009] Preferably, the outer wall of the clip is provided with a plurality of buckles evenly distributed, and the inner wall of the circular cavity is provided with a circular groove to match the buckles.

[0010] Preferably, a warning strip is provided at the bottom front end of the guardrail.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model uses a dustproof net to prevent dust from passing through the guardrails, thus suppressing dust. It also blocks flying gravel, preventing it from penetrating the guardrails and injuring pedestrians, thereby protecting them. The use of fasteners allows the dustproof net to be easily secured within the ring frame, facilitating quick installation and removal. The simple and convenient operation improves the efficiency of dustproof net installation and removal. The interplay of clips and slots increases the contact area between the pressure block and the ring frame, ensuring stable engagement of the pressure block within the ring frame and enhancing the stability of the dustproof net.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: A road and bridge construction safety device includes columns 2, which are arranged in a group to facilitate the support of guardrail 1; hanging rings 3 symmetrically arranged on the columns 2; and further includes: Multiple hooks 4 are symmetrically provided on the guardrail 1, and the hooks 4 are inserted into the hanging ring 3 to realize the installation of the guardrail 1; The dustproof net 5 is fixed to the rear end face of the guardrail 1 by fasteners. The use of the dustproof net 5 prevents dust from passing through the guardrail 1, thus playing a role in dust suppression. At the same time, it can also block flying gravel, preventing gravel from passing through the guardrail 1 and causing injury to pedestrians, thereby facilitating pedestrian protection. The use of fasteners makes it easy to snap the dustproof net 5 into the ring frame 7, thus facilitating the quick installation or removal of the dustproof net 5. The operation is simple and convenient, improving the work efficiency of installing or removing the dustproof net 5.

[0016] In this utility model, the fixing component includes an annular frame 7 set on the rear end face of the guardrail 1, and a pressure block 8 is provided inside the annular frame 7. The dustproof net 5 is fixed by the pressure block 8 being snapped into the annular frame 7.
