Description

Technical Field

[0001] The utility model relates to the technical field of safety protection in foundation pit construction, in particular to an underground exterior scaffolding foundation support under the condition of foundation pit slope. Background Technique

[0002] At present, many shallow foundation pits are excavated by slope, and the slope is protected by a steel mesh and fine stone concrete as a slope protection layer to prevent rainwater erosion.

[0003] After retrieval, the Chinese patent with the publication number CN214144596U discloses a building scaffolding support that can improve stability, including two mutually parallel rectangular hollow frames. A height adjustment mechanism is provided below the rectangular hollow frames, and a rotary support mechanism is provided at the lower end of the height adjustment mechanism. The beneficial effect of the utility model is that the height of the scaffolding can be adjusted arbitrarily according to the current working conditions through the action of the height adjustment mechanism, which is flexible to use and has stronger adaptability to working conditions. Through the action of the rotary support mechanism, the scaffolding can have a more stable center of gravity and prevent the scaffolding from moving.

[0004] Based on the above retrieval and in combination with the prior art, it is found that;

[0005] Although the above retrieved patent can adjust the height, the concrete protection layer of the slope will be damaged during the installation process. Once it rains, rainwater will enter the slope soil along the vertical pole. When the amount of rainwater exceeds a certain level, there is a risk of slope collapse, and the scaffolding body will also become unstable, resulting in safety accidents. Therefore, there are certain limitations. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an underground exterior scaffolding foundation support under the condition of foundation pit slope, which can avoid safety accidents caused by collapse and maintain the stability of the device.

[0007] The technical solution for realizing the purpose of the utility model is: an underground exterior scaffolding foundation support under the condition of foundation pit slope, including a pair of I-shaped steels, and a plurality of first channel steels are welded between the pair of I-shaped steels. An auxiliary steel plate is fixedly installed between the I-shaped steel and the first channel steel.

[0008] Preferably, a second channel steel is fixedly installed at the top of the pair of auxiliary steel plates.

[0009] Preferably, a support steel is fixedly installed between adjacent first channel steels, and the support steel is fixedly installed on the surface of the I-shaped steel.

[0010] Compared with the prior art, the utility model has the following remarkable advantages:

[0011] First: The utility model avoids damaging the concrete protective layer during the installation process, eliminates the risk of collapse, improves the safety and stability of construction, and the device ensures the safety of workers through multiple groups of support steels and auxiliary steel plates, preventing safety accidents from occurring;

[0012] Second: The device of the utility model effectively combines each component through welding, greatly improving in economy and safety, avoiding resource waste and unnecessary expenses, and facilitating the installation by workers.

[0013] It solves the problem that the concrete protective layer of the slope will be damaged during the installation process in the prior art. Once it rains, rainwater will enter the slope soil along the vertical pole. When the amount of rainwater exceeds a certain level, there will be a risk of slope collapse, and the scaffold body will also become unstable, resulting in safety accidents.

[0020] The following details the utility model, clearly and completely describes the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of them. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the utility model.

[0021] The utility model hereby provides an underground exterior - wall scaffold foundation support under the condition of foundation pit slope - cutting. The technical solution of the utility model is as follows:

[0022] As Figures 1-3As shown in the figure, a foundation support for an external scaffolding of a basement under the condition of slope excavation of a foundation pit includes a pair of I-shaped steel bars 1. A plurality of first channel steel bars 2 are welded between the pair of I-shaped steel bars 1. An auxiliary steel plate 4 is fixedly installed between the I-shaped steel bar 1 and the first channel steel bar 2 to prevent the first channel steel bar 2 from sliding down and maintain the stability and safety of the device.

[0023] Furthermore, a second channel steel bar 3 is fixedly installed at the top of the pair of auxiliary steel plates 4, which improves the operability and practicability and avoids the occurrence of safety accidents.

[0024] Furthermore, a support steel bar 5 is fixedly installed between adjacent first channel steel bars 2. The support steel bar 5 is fixedly installed on the surface of the I-shaped steel bar 1 to prevent the first channel steel bars 2 from breaking and improve the durability of the device.

[0025] The specific working method is as follows: This device is composed of a pair of I-shaped steel bars 1, multiple channel steel bars, and an auxiliary steel plate 4. Place the two short I-shaped steel bars 1 according to the slope of the slope. Weld the two first channel steel bars 2 to the I-shaped steel bars at a horizontal distance of 90 cm. Weld the auxiliary steel plate 4 at the angle between the first channel steel bar 2 and the I-shaped steel bar 1 to prevent the first channel steel bar 2 from being displaced. Then, weld another second channel steel bar 3 below the auxiliary steel plate 4 to fix the two I-shaped steel bars 1 and prevent the auxiliary steel plate 4 from sliding down. In this way, the two lower second channel steel bars 3 and the I-shaped steel bars form a mouth shape to ensure the stability of the support. The two first channel steel bars 2 are used to place the vertical poles of the external scaffolding.
