Description

Technical Field

[0001] This utility model belongs to the technical field of construction safety equipment, specifically, it relates to a modular highway bridge construction site safety railing. Background Technology

[0002] Prefabricated highway bridge construction site guardrails are a type of safety protection facility specifically designed for highway bridge construction sites. They typically consist of components such as posts, crossbars, guardrail panels or mesh panels, and connectors.

[0003] Chinese patent CN215168713U discloses a safety guardrail for construction, including a single guardrail panel, guardrail inserts, and connecting components. The guardrail inserts are vertically connected with fasteners. The lower ends of the vertical bars of the single guardrail panel are inserted into the guardrail inserts and fixed by the fasteners. The single guardrail panels are detachably connected by the connecting components to form an integral guardrail. The connecting components include a pair of clamping plates and bolts LS and nuts LM. The clamping plates are arched plates with straight sections in the middle and at both ends. The two clamping plates are arranged close together at the middle section, and their two ends clamp the vertical bars of adjacent single guardrail panels and are locked together by bolts and nuts.

[0004] When using the above-mentioned guardrails, bolts are required for connection, which is troublesome and time-consuming to assemble. Utility Model Content

[0005] The purpose of this invention is to provide a modular highway bridge construction site guardrail that simplifies the assembly process and improves assembly efficiency.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A modular highway bridge construction site safety barrier includes several posts, each 1-1.2m high, with a safety barrier between adjacent posts. Several rollers are mounted on the bottom wall of each safety barrier. Several connecting blocks are mounted on each post, arranged along the height of the post. The safety barrier has pins that connect to the connecting blocks, and each connecting block has a locking mechanism for the pins. By inserting pins into slots and locking them with the locking mechanisms, a bolt connection is replaced, improving installation convenience.

[0008] In one specific implementation, the connecting block is provided with a slot that extends through to the side wall of the connecting block. A pin is inserted into the slot. Each opposite side wall of the slot has a through hole. The positioning element is an arc-shaped rod inserted into the through hole. The pin includes a horizontal bar connected to the guardrail and a connecting rod connected to the horizontal bar. Space is left between the connecting rod and the guardrail for insertion into the slot wall. During installation, the guardrail is moved, and the connecting rod on the guardrail is slidably inserted into the slot. Then, the arc-shaped tube passes through the two through holes to achieve splicing, which is efficient and simple.

[0009] In one specific implementation, the bottom wall of the column is provided with several through holes for screws to pass through. The through holes facilitate locking the column.

[0010] In one specific implementation, the outer wall of the post is coated with a layer of marking paint. This marking paint layer facilitates the identification of the guardrail.

[0011] This utility model adopts a connection structure that combines a pin and a connecting block. The pin can be directly inserted into the slot of the connecting block, and then locked by passing through the through hole on the side wall of the slot with an arc-shaped rod as a positioning element. This eliminates the traditional bolt connection method, greatly simplifies the splicing process of the guardrail, significantly improves the splicing efficiency, and saves construction time and labor costs.

[0016] Reference Figures 1-3 A prefabricated highway bridge construction site guardrail includes several posts 1, each post 1 being 1-1.2m high. A positioning plate 12 is provided on the bottom wall of each post 1, and the positioning plate 12 has several through holes 13 for screws to pass through. The outer wall of each post 1 is coated with a marking paint layer.

[0017] A guardrail 2 is provided between two adjacent posts 1. The guardrail 2 includes an outer frame 14 and several guardrails 15 set inside the outer frame 14. Several rollers 11 are provided on the bottom wall of the guardrail 2.

[0018] The column 1 is provided with a connecting block 3, and there are several connecting blocks 3. The several connecting blocks 3 are arranged along the height direction of the column 1. In this embodiment, there are two connecting blocks 3. The connecting block 3 is provided with a slot 6. The slot 6 is arranged vertically and extends through to the side wall of the connecting block 3. The opposite side walls of the slot 6 are provided with through holes 7. In this embodiment, one side wall of the slot 6 is provided with two through holes 7.

[0019] The guardrail 2 is provided with a pin 4 connected to the connecting block 3. The pin 4 includes a horizontal bar 9 connected to the outer frame 14 and a plug 10 connected to the horizontal bar 9. In this embodiment, the horizontal bar 9 and the plug 10 are integrally formed and are L-shaped. The plug 10 is inserted into the slot 6. At this time, the horizontal bar 9 is located above the connecting block 3, and there is space between the plug 10 and the guardrail 2 for the slot wall of the slot 6 to be inserted.

[0020] The connecting block 3 is equipped with a positioning element 5 for locking pin 4. The positioning element 5 is an arc-shaped rod 8 that is inserted into the through hole 7.
