Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to a reusable edge protection device. Background Technology

[0002] During the foundation pit construction phase, safety requirements necessitate the installation of retaining walls and edge protection devices around the pit to prevent rainwater from flowing into it and causing accidents due to personnel accidentally falling in. Traditional retaining walls are constructed by bricklaying and plastering, with plain concrete piers poured at the guardrail posts, and then secured with expansion bolts. The drawbacks of this method are that the expansion bolts embedded in the concrete are frequently damaged during excavation and construction, and the frequent disassembly and reassembly can also damage them. When the guardrail is restored, the expansion bolts need to be re-inserted, causing inconvenience. Furthermore, guardrails installed in this way are not very secure and have poor horizontal load-bearing capacity. Therefore, a reusable, safe, and robust edge protection device is needed. Utility Model Content

[0003] The purpose of this invention is to provide a reusable edge protection device that solves the problem of poor stability and instability caused by drilling holes and using expansion bolts to fix traditional edge protection on retaining walls.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a reusable edge protection device, comprising a precast concrete waterproof retaining wall, wherein two embedded parts are provided on the precast concrete waterproof retaining wall, and columns are detachably provided on the embedded parts via connecting components. A guardrail is detachably provided between the two columns via connecting components, and a kick plate is provided below the guardrail.

[0006] Furthermore, one end of the precast concrete waterproof retaining wall is configured as a socket, and the other end of the precast concrete waterproof retaining wall is configured as a spigot.

[0007] Furthermore, a rubber waterstop strip is provided on one side of the socket.

[0008] Furthermore, a grout-filled area is provided around the rubber waterstop strip.

[0009] Furthermore, the column is provided with a first connecting piece, and the guardrail is provided with a second connecting piece, the first connecting piece and the second connecting piece are connected together by a connecting assembly.

[0010] Furthermore, when it is necessary to connect the two columns together, a third connecting piece is provided on the side of the two adjacent first connecting pieces, and the third connecting piece and the first connecting piece are connected together by a connecting assembly.

[0011] Furthermore, the connecting assembly includes a screw, and the first connecting piece, the second connecting piece, and the third connecting piece are all provided with bolt holes that match the screw, and the screw is provided with a nut and a washer.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model includes a precast concrete waterproof retaining wall. Two embedded parts are provided on the precast concrete waterproof retaining wall, and columns are installed on the embedded parts via connecting components. A guardrail is installed between the two columns, and a kickboard is installed below the guardrail for easy installation and improved construction speed. After construction, the edge protection becomes a unified whole, making it more robust, safe, and durable. It is not only waterproof but also reusable, easy to assemble and disassemble, and saves labor and material costs, making it highly valuable for widespread application. Attached Figure Description

[0023] like Figure 1-7As shown, a reusable edge protection device includes a precast concrete waterproof retaining wall 1, in which two embedded parts 3 are pre-embedded. A column 4 is detachably installed on the embedded part 3 via a connecting component. A guardrail 10 is detachably installed between the two columns 4 via a connecting component. A kick plate 9 is connected to the bottom of the guardrail 10.

[0024] like Figure 2-3 As shown, one end of the precast concrete waterproof retaining wall 1 is set as a socket, and the other end of the precast concrete waterproof retaining wall 1 is set as a spigot. A rubber waterstop strip 2 is provided on one side of the socket. The gap around the rubber waterstop strip 2 is a grout filling area 13. When two precast concrete waterproof retaining walls 1 are connected together, the socket and spigot are connected together to press down the rubber waterstop strip 2, making the retaining wall tighter and leak-proof. The grout filling area 13 around the rubber waterstop strip 2 is filled with grout.

[0025] like Figure 4 As shown, the column 4 is connected to a first connecting piece 8, specifically, one side of the column 4 is connected to two first connecting pieces 8, such as... Figure 5 As shown, the guardrail 10 is connected to a second connecting piece 11. Two second connecting pieces 11 are connected to both the left and right sides of the guardrail 10. The first connecting piece 8 and the second connecting piece 11 are connected together by a connecting assembly.

[0026] like Figure 6 As shown, when it is necessary to connect the two columns 4 together, a third connecting piece 12 is provided on the side of the two adjacent first connecting pieces 8, and the third connecting piece 12 and the first connecting piece 8 are connected together by a connecting assembly.

[0027] like Figure 7 As shown, the connecting assembly includes a screw 5, and bolt holes matching the screw 5 are provided on the first connecting piece 8, the second connecting piece 11 and the third connecting piece 12. A nut 6 is threaded onto the screw 5, and a washer 7 is also fitted onto the screw 5. The embedded part 3 has two bolt holes matching the screw 5.
