Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a foundation pit edge guardrail. Background Art

[0002] During construction at a construction site, protective devices need to be installed on adjacent areas such as foundation pits to prevent construction workers from accidentally falling from heights and causing harm to the construction workers.

[0003] The Chinese utility model patent with announcement number CN219864463U discloses a foundation pit edge protection device, which relates to the technical field of building protection equipment, including a concrete base, wherein several concrete bases are arranged and the several concrete bases are distributed at equal distances, and columns are buried in the concrete base, and the columns extend to the top of the concrete base, and two clamping mechanisms are provided on the movable sleeves on the outer surfaces of the columns, and the two clamping mechanisms are arranged in an upper and lower staggered manner, and an iron fence is commonly arranged between two adjacent columns, and the iron fence is fixedly connected to the adjacent clamping mechanism.

[0004] This utility model reduces the difficulty of installing the iron fence and makes the angle between two adjacent iron fences more flexible. However, the use of a concrete base to fix the iron fence is not convenient for construction workers to move and store it. In addition, due to the long length of the edge of the foundation pit, the overall length of the guardrail formed by multiple interconnected iron fences is too long, resulting in poor anti-lodging ability of the guardrail as a whole. Utility Model Content

[0005] Based on this, it is necessary to provide a foundation pit edge guardrail to overcome the defects mentioned in the above background technology.

[0006] A foundation pit edge guardrail comprises a column, the bottom of the column is connected to the ground, fixed shafts are arranged on both sides of the column, diagonal braces connected to the ground are arranged on both sides of the fixed shaft, a plurality of the columns are arranged at intervals, a protective net is arranged between adjacent columns, L-shaped rotating shafts are arranged on both sides of the protective net, and the rotating shafts are movably connected to the fixed shafts.

[0007] As a preferred embodiment of the foundation pit edge guardrail in the utility model, a fixing seat is provided at the bottom of the column.

[0008] As a preferred embodiment of the foundation pit edge guardrail in the utility model, the fixed shaft is provided with a mounting hole parallel to its axial direction, and the fixed shaft includes an upper fixed shaft and a lower fixed shaft.

[0009] As a preferred embodiment of the foundation pit edge guardrail in the utility model, the diagonal brace includes a first diagonal brace and a second diagonal brace. The first diagonal brace is arranged on the outside of the column, one end of which is connected to the upper fixed shaft, and the other end of which is connected to the ground. The second diagonal brace is arranged on the inside of the column, one end of which is connected to the lower fixed shaft, and the other end of which is connected to the ground.

[0010] As a preferred embodiment of the foundation pit edge guardrail of the utility model, gaskets are provided at the bottom of the first diagonal brace and the second diagonal brace.

[0011] As a preferred embodiment of the foundation pit edge protection fence in the utility model, the bottom of the protection net is connected to the ground.

[0012] Beneficial effects of the utility model:

[0013] The columns in the utility model are connected to the ground by bolts, and the connection is firm and reliable, which is convenient for moving and storing. The diagonal braces not only enhance the anti-lodging performance of the guardrail, but also prevent construction workers from getting too close to the guardrail when passing by the foundation pit, which can effectively avoid the occurrence of height falling accidents.

[0026] Example

[0027] A foundation pit edge guardrail, such as Figure 1 to Figure 3 As shown, it includes a column 1 and a protective net 4 rotatably connected thereto, a plurality of the columns 1 are arranged around the foundation pit, and the bottoms thereof are connected to the ground via expansion bolts, and fixed shafts 2 for connecting the protective net 4 are arranged on both sides thereof, and diagonal braces 3 are arranged on the fixed shaft 2 close to and away from the foundation pit side, and the protective net 4 is arranged between two adjacent columns 1, and is movably connected to the fixed shaft 2 via L-shaped rotating shafts 5 on both sides.

[0028] By setting the diagonal brace 3, the anti-collapse performance of the guardrail can be effectively enhanced to prevent it from easily collapsing in severe weather or under the impact of personnel or equipment. At the same time, the movable angle between the column 1 and the protective net 4 can be increased by fixing the axis 2 and the rotating axis 5, so that the guardrail can better fit the shape of the foundation pit.

[0029] In this embodiment, the diagonal brace 3 includes a first diagonal brace 31 and a second diagonal brace 32. The first diagonal brace 31 is arranged on the outside of the column 1, that is, away from the foundation pit side, one end of which is intercepted by the upper fixed shaft 21, and the other end of which is connected to the ground through an expansion bolt. The second diagonal brace 32 is arranged on the inside of the column 1, that is, close to the foundation pit side, one end of which is connected to the lower fixed shaft 22, and the other end of which is in contact with the ground, so as to reduce the edge operation during installation and reduce the occurrence of safety accidents. The bottom of the first diagonal brace 31 and the second diagonal brace 32 is provided with a gasket 7 to increase the contact area between the first diagonal brace 31 and the second diagonal brace 32 and the ground, and the gasket 7 connected to the second diagonal brace 32 should have a large friction coefficient with the ground contact side.

[0030] By adopting the above structure, while increasing the anti-falling performance of the guardrail, the first diagonal brace 31 can also play a certain hindering role on the workers passing close to the guardrail, preventing them from walking close to the edge of the foundation pit and reducing the occurrence of falling accidents.

[0031] In this embodiment, a fixing seat 6 is provided at the bottom of the column 1, and a bolt hole is provided on the fixing seat 6. The column 1 is connected to the ground by an expansion bolt passing through the bolt hole. A reinforcement plate can also be added between the fixing seat 6 and the bottom of the column 1 to further enhance the anti-lodging performance of the column 1.

[0032] In this embodiment, the fixed shaft 2 includes a pair of upper fixed shafts 21 and a pair of lower fixed shafts 22 that are arranged in opposition to each other. The upper fixed shafts 21 and the lower fixed shafts 22 have mounting holes parallel to their axial directions, and the mounting holes need to have a downward opening.

[0033] In this embodiment, the bottom of the protection net 4 is connected to the ground, and the fixing seats 6 are located on both sides thereof to facilitate the installation of the protection net 4 .

[0034] During installation, first fix a single piece of protective net 4 to the edge of the foundation pit, then connect a single column 1 with its rotating shaft 5 through the fixed shaft 2, and then fix the column 1; fix another piece of protective net 4 on the side not connected to the column 1, and fix two adjacent protective nets 4 through another column 1, repeat the above steps until the guardrail is enclosed, and complete the enclosed installation through the last column 1.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
