Abstract
Description
Technical Field
[0001] This utility model belongs to the field of temporary building access technology, specifically relating to a deep foundation pit adjacent to a building access device. Background Technology
[0002] Currently, during the construction of deep foundation pits in building projects, temporary passages need to be built between the edge of the deep foundation pit and the edge of the building inside the pit to ensure the passage of construction personnel and the transportation of building materials. However, due to the large differences in the depth of the deep foundation pit, the dynamic changes in the horizontal distance and elevation difference between the edge of the foundation pit and the edge of the building, and the fact that the building walls are often not fully formed, the existing passage construction technology has obvious limitations: either fixed-size passages are used, which cannot adapt to different horizontal distances and elevation differences, requiring frequent disassembly and reassembly or additional splicing, which is cumbersome and inefficient; or the passage support structure is poorly designed, with the building end supports directly fixed to the wall, which can easily cause wall cracking and structural damage, affecting the subsequent construction quality.
[0003] (1) The traditional passage mode is a steel pipe coupler pedestrian ramp, which is often used in a straight line or a zigzag shape depending on the height. This passage is erected using coupler-type steel pipe scaffolding, which takes a long time to erect and dismantle, and requires the installation of steel pipes and couplers one by one. There are relatively more safety hazards, and the connection quality of the coupler nodes is significantly affected by the quality of the couplers themselves and the operation of the workers. (2) Traditional channel devices have fixed dimensions after installation. When reused elsewhere, they often need to be completely removed and some parts may be discarded because they do not match the new distance and height difference. This invention can adapt to the dynamic changes in the horizontal distance and height difference between the pit edge and the building edge by flexibly adjusting the angle and length. (3) Traditional channel devices are relatively expensive; some finished channels are heavy, inconvenient to transport and require high-quality hoisting equipment. This invention, due to its simple design and flexibility, reduces manufacturing costs, improves the cost-effectiveness of the channel, and reduces the weight of the channel, making it convenient to transport and install. Utility Model Content
[0004] To address the aforementioned issues, this utility model discloses a deep foundation pit adjacent building side passage device, which can serve as a passage for goods turnover or pedestrians. It is adjustable in length and elevation, simple to manufacture, and convenient to transfer, thereby improving on-site operation efficiency.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: The deep foundation pit adjacent building access device includes a steel plate, a folded steel plate, a channel steel, telescopic diagonal braces, and a support base. The channel steel is welded to both sides of the steel plate, and the channel steel extends backward along both sides of the steel plate to form a connecting part. The connecting part has multiple connecting holes. The folded edge of the side of the folded steel plate is inserted into the connecting part and connected by bolts. An adjustable support base is connected to the bottom of the folded steel plate. The upper ends of the four telescopic diagonal braces are connected to the channel steel through fixed hinge supports, and the lower ends of the telescopic diagonal braces are respectively fixed to both sides of the foundation pit through detachable hinge supports.
[0006] As a supplement to this utility model, the support base has turnbuckles as its rods, which can be adjusted by a side knob.
[0007] As a supplement to this utility model, the telescopic diagonal rod has turnbuckles as its members and can be adjusted by a side knob.
[0008] As a supplement to this utility model, the detachable hinge support is fixed to the fixing plate by bolts, and the fixing plate is fixed on both sides of the foundation pit.
[0009] As a supplement to this utility model, the fixed hinge support is welded to the outer end of the channel steel.
[0010] As a supplement to this utility model, four telescopic diagonal braces are respectively set on both sides of the channel steel.

[0012] As a supplement to this utility model, vertical detachable guardrails are provided on both sides of the steel plate.
[0013] The beneficial effects of this utility model are as follows: (1) This utility model is simple to build, sturdy and safe, and improves on-site operation efficiency; (2) The present invention can flexibly adjust the length and size of the protruding end, and can meet the changes in the height difference and horizontal length between the edge of the foundation pit and the edge of the building within a certain range; (3) This utility model can be fully utilized, is easy to transfer, and has low usage cost.

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0024] As shown in the figure, the deep foundation pit adjacent building side passage device of this utility model includes a steel plate 1, a folded steel plate 2, a channel steel 9, a telescopic diagonal brace 4, and a support base 3. The channel steel 9 is welded to both sides of the steel plate 1. The channel steel 9 extends backward along both sides of the steel plate to form a connecting part 11. The connecting part 11 is provided with multiple connecting holes 12. The folded edge of the side of the folded steel plate 2 is inserted into the connecting part 11 and connected by bolts 7. The adjustable support base 3 is connected to the bottom of the folded steel plate 2. The upper ends of the four telescopic diagonal braces 4 are connected to the channel steel 9 through fixed hinge supports 8. The lower ends of the telescopic diagonal braces 4 are respectively fixed to both sides of the foundation pit through detachable hinge supports 5.
[0025] The deep foundation pit adjacent building side passage device described in this utility model is constructed in the following order: Figure 3As shown, first fix the steel plate 1, then install the folded steel plate 2, and then adjust the angle and length of the folded steel plate 2. The length of the extended end of the folded steel plate 2 can be flexibly adjusted to meet the changes in the height difference and horizontal length between the edge of the foundation pit and the edge of the building within a certain range. After the steel plate 1 is assembled, the upper end rests on the slope of the foundation pit, the lower end is attached to the upper edge of the folded steel plate 2, and the lower edge of the folded steel plate 2 is supported on the ground. It can be used as a passage for goods turnover or pedestrians. The surfaces of the steel plate 1 and the folded steel plate 2 have anti-slip textures. Vertical detachable guardrails 10 are provided on both sides of the steel plate 1 to increase safety. This device is detachable, easy to move, and has low operating costs.
[0026] The support base 3 of this utility model has turnbuckles as its rods, which can be adjusted by a side knob to adjust the height and angle of the folded steel plate 2.
[0027] The telescopic diagonal brace 4 described in this utility model uses turnbuckles as its components and can be adjusted via a side knob. The height and angle of the steel plate 1 can be adjusted by adjusting all four telescopic diagonal braces 4 together.
[0028] The detachable hinged support 5 of this invention is fixed to the fixing plate 6 by bolts, and the fixing plate 6 is fixed to both sides of the foundation pit. The fixing plate 6 covers the edge of the building to prevent the support from being directly fixed to the building and damaging it.
