Description

Technical Field

[0001] This utility model belongs to the field of engineering construction technology, specifically relating to components used for the protection of foundation pits of old buildings. Background Technology

[0002] Foundation pit retaining is a method used to develop and utilize underground space for the construction of various underground buildings such as multi-story basements, subways, and underground commercial streets. By setting up a support structure, it can effectively resist the active earth pressure and groundwater pressure generated during excavation, prevent pit wall collapse, and ensure construction safety.

[0003] For example, in the Chinese utility model with announcement number CN214783959U, entitled "A Foundation Pit Retaining Structure for Building Construction", although the retaining plate can be compressed and supported by inserting the insert into the slot of the retaining plate, and the insert can be pulled out of the slot by rotating the handle to release the retaining plate, the angle of the retaining plate cannot be adjusted, and it cannot better adapt to different working environments. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed component for the protection of foundation pits in old buildings in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A component for the protection of foundation pits of old buildings includes a base, a guardrail fixedly connected to the upper surface of the base by screws, a connecting rod fixedly connected to the upper surface of the base, a first fixing structure provided on the side of the guardrail, and a second fixing structure provided between the two guardrails.

[0007] As a further optimization of this utility model, the second fixing structure includes a plurality of protrusions fixedly connected to the front side of the guardrail, and each of the plurality of protrusions is provided with a fixing rod fixedly connected by screws on its upper side.

[0008] As a further optimization of this utility model, a connecting rod is fixedly connected to the upper surface of the base, and the first fixing structure includes a mounting plate fixedly connected to the outside of the connecting rod. A plurality of fixing holes are opened on the upper side of the mounting plate, and a connecting plate is fixedly connected to the side of the guardrail.

[0009] As a further optimization of this utility model, the connecting plate and the fixing hole are connected by screws.

[0010] As a further optimization of this utility model, a mounting rod is fixedly connected to the bottom end of the base, and the mounting rod is conical.

[0011] As a further optimization of this utility model, all of the aforementioned fixing rods are parallel to the mounting plate.

[0012] The beneficial effects of this utility model are as follows: This utility model connects multiple guardrails through the cooperation of the mounting plate and the fixing hole. After the angle between the multiple guardrails is adjusted, the position of the two guardrails is fixed by the cooperation between the protrusion and the fixing rod. The slope, unevenness and other unevenness that may exist at the construction site can be avoided by adjusting the angle of the guardrail to prevent the guardrail from tilting or slipping, thereby enhancing the stability and safety of the guardrail.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the component for the protection of foundation pits of old buildings includes a base 1. An installation rod 6, conical in shape, is fixedly connected to the bottom of the base 1. The installation rod 6 is inserted into the ground beside the foundation pit to fix the overall position, facilitating the subsequent maintenance of the overall stability of the foundation pit. A guardrail 2 is fixedly connected to the upper surface of the base 1 with screws. The guardrail 2 prevents the pit wall from collapsing and restricts the displacement of the surrounding soil, avoiding impact on the safety of nearby buildings, pipelines, and other facilities. A connecting rod 3 is fixedly connected to the upper surface of the base 1, located between two guardrails 2. An installation plate 401 is fixedly connected to the outer side of the connecting rod 3. In this invention, the number of installation plates 401 on the connecting rod 3 is three, but the specific number can be changed according to actual conditions. Several fixing holes 402 are opened on the upper side of the installation plate 401. A connecting plate 403 is fixedly connected to the side of the guardrail 2. The U-shaped structure is snapped onto the mounting plate 401. The connecting plate 403 is connected to the fixing hole 402 by screws. The mounting plate 401 is supported by the connecting rod 3. Multiple guardrails 2 are connected together through the cooperation of the mounting plate 401, fixing hole 402, connecting plate 403 and screws. This also makes it convenient for workers to splice or disassemble the guardrails 2 according to the size of the foundation pit, which can adapt to different foundation pit sizes. Several protrusions 501 are fixedly connected to the front of the guardrail 2. Each of the protrusions 501 is provided with a fixing rod 502 fixedly connected by screws on its upper side. The fixing rods 502 are parallel to the mounting plate 401. After adjusting the angle between the guardrails 2 through the cooperation of the protrusions 501, fixing rods 502 and screws, the guardrail 2 is fixed in position. This can adapt to foundation pits of different shapes, facilitate construction by workers, and prevent pit collapse to ensure the safety of workers.

[0021] It should be noted that, when using this component for the protection of foundation pits of old buildings, the workers fix the entire assembly in the ground by cooperating with the base 1 and the mounting rod 6. Then, the connecting plate 403 is fixed to the mounting plate 401 by cooperating with the screws and fixing holes 402. When it is necessary to maintain an irregular foundation pit, the angle between the two guardrails 2 is adjusted, and then the fixing rod 502 is fixed to the protrusion 501 by screws, so that the position of the two guardrails 2 is fixed, which facilitates the subsequent maintenance of the foundation pit.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
