A type of protective railing for deep foundation pit construction sites

Abstract

This utility model relates to the technical field of deep foundation pit protective railings, and in particular to a protective railing for deep foundation pit construction sites. It includes posts and a base. The base is fixedly connected to the lower end of the post. Multiple supports are equidistantly fixed to both sides of the outer wall of the post. Multiple protrusions are equidistantly fixed to the left and right ends of the outer wall of the protective railing. Each protrusion has a plug fixed to its lower end, and the plug is inserted into the supports. Through the cooperation between the posts, plugs, slots, the protective railing, and hooks, and by using counterweights and the self-weight of the protective railing, the protective railing is stably installed between adjacent posts. It also effectively alerts nearby workers at night by reflecting moonlight or weak artificial light through reflective sheets. This effectively avoids the need for four to six bolts to connect the protective railing grid and the posts, which hinders quick disassembly and replacement, and fails to alert workers to the protective issue in low light conditions.

Description

Technical Field

[0001] This utility model relates to the technical field of deep foundation pit protective railings, specifically a protective railing for deep foundation pit construction sites. Background Technology

[0002] With the rapid development of the modern construction industry and the continuous updating of construction methods, there are more and more deep foundation pit construction sites. In order to ensure the safety of workers and prevent people or materials from falling into the deep foundation pit during construction, protective railings need to be installed. For example, a protective railing for a deep foundation pit construction site with application number "202420030918.X" includes a base plate, and two support legs are fixedly connected to the lower surface of the base plate.

[0003] However, although it can use multiple casters to adjust the position of the guardrail, the existing guardrail grid structure basically requires four to six bolts to connect the guardrail grid and the post during installation. The guardrail grid is also relatively easy to be damaged, so it cannot be quickly disassembled and replaced, and it cannot alert workers to the guardrail problem in low light conditions. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing installation process of this device basically requires the installation of four to six bolts to connect the guardrail grid and the post, and the guardrail grid is relatively easy to be damaged, so it cannot be quickly disassembled and replaced, and it cannot alert workers to the protection problem in low light conditions. Therefore, a protective railing for deep foundation pit construction sites is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a protective railing for a deep foundation pit construction site, including a post and a base. The base is fixed to the lower end of the post. Multiple supports are fixed at equal intervals on both sides of the outer wall of the post. A protective railing is provided on the inner side of the post on both sides. Multiple protrusions are fixed at equal intervals on the left and right ends of the outer wall of the protective railing. Each protrusion has a plug fixed to its lower end. The plug is inserted into the support.

[0007] Preferably, the inner wall of the bracket is machined with a slot, and both the outer wall of the insert and the inner wall of the slot are machined into a tapered shape.

[0008] Preferably, a vertical plate is provided at the center of the front side of the outer wall of the guardrail, and multiple hooks are fixedly connected at equal intervals at the upper end of the vertical plate. The hooks are connected to the inner wall grid of the guardrail, and multiple reflectors and counterweights are fixedly connected to the front and rear sides of the vertical plate respectively.

[0009] Preferably, the outer wall of the counterweight bar is fitted to the inner wall grid of the guardrail.

[0010] Preferably, bolts are installed on the inner walls of the four corners of the base, and support plates are fixed to the lower front and rear sides of the outer wall of the column.

[0011] The protective railing for deep foundation pit construction sites proposed in this utility model has the following advantages:

[0012] The combination of posts, inserts, slots, guardrails, counterweights, reflectors, and hooks allows for rapid installation of the inserts and slots. The counterweights and the weight of the guardrails themselves ensure stable installation between adjacent posts. The reflectors effectively alert nearby workers to the presence of the guardrail at night by reflecting moonlight or dim light. This design avoids the need for four to six bolts to connect the guardrail grid to the posts, which are easily damaged and cannot be quickly disassembled or replaced. Furthermore, it fails to alert workers to the presence of the guardrail in low-light conditions. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-5In this embodiment, a protective railing for a deep foundation pit construction site includes a post 1 and a base 2. The base 2 is fixedly connected to the lower end of the post 1. Multiple supports 3 are fixedly connected at equal intervals on both sides of the outer wall of the post 1. A protective railing 9 is provided on the inner side of the two sides of the post 1. The protective railing 9 is composed of a grid structure consisting of an outer frame and internal horizontal and vertical railings. Multiple protrusions 4 are fixedly connected at equal intervals on the left and right ends of the outer wall of the protective railing 9. Each protrusion 4 has a plug 5 fixedly connected to its lower end. The plug 5 is inserted into the support 3. The inner wall of the support 3 is machined with a slot 6. The outer wall of the plug 5 and the inner wall of the slot 6 are both machined into a conical shape. The conical surface makes it easier for the plug 5 and the slot 6 to fit together.

[0021] See attached document Figure 1-5 In this embodiment, a vertical plate 12 is provided at the center of the front side of the outer wall of the guardrail 9. Multiple hooks 10 are fixed at equal intervals on the upper end of the vertical plate 12. The vertical plate 12 can be directly hung on the grid of the guardrail 9 through the hooks 10. The combination of the guardrail 9 and the post 1 forms a guardrail structure. The hooks 10 are connected to the inner wall grid of the guardrail 9. Multiple reflectors 11 and counterweights 13 are fixed to the front and rear sides of the vertical plate 12, respectively. The counterweights 13 are used to increase the overall weight and make the guardrail 9 more stable. The outer wall of the counterweights 13 is in contact with the inner wall grid of the guardrail 9. Bolts 8 are installed on the inner walls of the four corners of the base 2. Support plates 7 are fixed to the front and rear sides of the lower outer wall of the post 1. The support plates 7 can increase the support capacity between the post 1 and the base 2.

[0022] Working principle:

[0023] When protective railings are needed at this deep foundation pit construction site, firstly, multiple posts 1 and bases 2 are placed equidistantly around the deep foundation pit, and the bases 2 are connected to the ground around the deep foundation pit using bolts 8. Then, each guardrail 9 with protrusions 4 and inserts 5 is moved between two adjacent posts 1, and the positions of the inserts 5 and holes 6 are aligned and inserted from top to bottom, thus installing the guardrail 9 between adjacent posts 1. Next, vertical plates 12 with counterweights 13 and reflectors 11 are hung on the grid of the guardrail 9 using hooks 10. The counterweights 13 and the weight of the guardrail 9 themselves ensure stable installation between adjacent posts 1. The reflectors 11 effectively alert nearby workers to the need for protection at night by reflecting moonlight or weak light. Compared to existing guardrail grid structures, this method requires significantly more time during installation. The traditional method requires four to six bolts to connect the guardrail grid and the posts. However, the guardrail grid is easily damaged, making quick disassembly and replacement impossible. Furthermore, it fails to alert workers to the danger of the guardrail in low light conditions. This design, however, utilizes inserts 5 and slots 6 for rapid installation. The weight of the counterweight 13 and the guardrail 9 itself ensures stable installation between adjacent posts 1. Reflectors 11 effectively alert nearby workers at night using moonlight or weak artificial light. This design effectively avoids the limitations of existing installation methods that require four to six bolts to connect the guardrail grid and posts, which are prone to damage and cannot be quickly disassembled or replaced, nor can they alert workers to the danger of the guardrail in low light conditions.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
