Description

Technical Field

[0001] This utility model belongs to the field of foundation pit support technology, specifically a double-layer inclined bracing connection structure for foundation pit support. Background Technology

[0002] With the acceleration of urbanization, the number of high-rise buildings, underground space development, and infrastructure construction projects is increasing, leading to a rise in deep foundation pit projects. These projects often face complex geological conditions, environmental constraints, and stringent time and safety requirements. Therefore, ensuring the stability of the foundation pit during excavation and preventing its collapse and damage to surrounding buildings has become a key focus of foundation pit support technology research. Traditional foundation pit support technologies, such as single-row piles, diaphragm walls, and double-layer inclined columns, can meet the stability requirements of foundation pits to a certain extent. However, they often fall short when dealing with foundation pits of varying depths, complex geological conditions, or projects with high environmental protection requirements. Furthermore, traditional support technologies, due to welding, result in long construction cycles, high costs, and inconvenience in adjusting the angle of the support columns according to the different depths of the foundation pit, leading to insufficient foundation pit stability and increasing the risk of collapse. Therefore, improvements and optimizations are needed. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a double-layer inclined bracing connection structure for foundation pit support.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-layer inclined bracing connection structure for foundation pit support, comprising a vertical plate, a horizontal plate fixedly installed at the bottom of the vertical plate, an adjusting block slidably installed at the top of the horizontal plate, a rotating rod rotatably installed inside the adjusting block and extending to the outside of the adjusting block, and a blocking block fixedly installed at one end of the rotating rod.

[0005] Preferably, a fixing post is fixedly installed on the side of the vertical plate near the horizontal plate, and two sliders are slidably installed inside the fixing post. Two bolts are rotatably installed on both sides of the two sliders, and a locking block is threaded onto the outer surface of the bolt.

[0006] Preferably, a sliding rod is fixedly installed inside the fixed column, and both sliders are slidably sleeved on the outer surface of the sliding rod.

[0007] Preferably, the top of the adjusting block is hinged with a diagonal brace, and the other end of the diagonal brace is hinged to two sliders respectively.

[0008] Preferably, both sliders are slidably mounted on the surface of the diagonal brace, and the locking block is engaged with the diagonal brace.

[0009] Preferably, a fixing block is fixedly installed on the top of the horizontal plate, and the fixing block is engaged with the blocking block.

[0010] Preferably, a torsion spring is fixedly installed inside the adjusting block, and the torsion spring is fixedly sleeved on the outer surface of the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a rotating rod and adjusting block to further twist the torsion spring. The elastic potential energy of the torsion spring allows the blocking block to engage or disengage with the fixing block, enabling workers to adjust the support angle of the diagonal bracing column according to the specific depth and requirements of the foundation pit. Compared to traditional devices, this flexible adjustment can adapt to foundation pits of varying depths, allowing for adjustments to the support angle and force based on the pit's depth. This mechanism allows workers to adjust the support angle of the diagonal bracing column in real time according to the specific depth of the foundation pit, ensuring the support structure always matches the actual needs of the pit. This high adaptability not only enhances the stability of the support system but also effectively prevents insufficient or excessive support due to changes in pit depth, enabling precise control of the support angle. This precision helps optimize the stress distribution of the support structure, improving the overall load-bearing capacity and stability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 8 As shown, this utility model provides a double-layer inclined bracing connection structure for foundation pit support, including a vertical plate 1, a horizontal plate 2 fixedly installed at the bottom of the vertical plate 1, an adjusting block 3 slidably installed at the top of the horizontal plate 2, a rotating rod 4 rotatably installed inside the adjusting block 3 and extending to the outside of the adjusting block 3, and a blocking block 5 fixedly installed at one end of the rotating rod 4.

[0024] By rotating the rotating rod 4, the torsion spring 6 is further twisted due to the rotation rod 4 and the adjusting block 3. The elastic potential energy of the torsion spring 6 causes the blocking block 5 to engage with and disengage from the fixing block 13. This allows workers to adjust the support angle of the diagonal bracing column 7 according to the specific depth and needs of the foundation pit. Compared with traditional devices, this flexible adjustment can adapt to foundation pits of different depths, thereby adjusting the support angle and support force according to the different depths of the foundation pit. This mechanism allows workers to adjust the support angle of the diagonal bracing column in real time according to the specific depth of the foundation pit, ensuring that the support structure always matches the actual needs of the foundation pit. This high adaptability not only enhances the stability of the support system, but also effectively prevents the problems of insufficient or excessive support caused by changes in the depth of the foundation pit, thus achieving precise control of the support angle. This precision helps to optimize the stress distribution of the support structure and improve the overall load-bearing capacity and stability of the structure.

[0025] like Figures 1 to 8 As shown, a fixing post 8 is fixedly installed on the side of the vertical plate 1 near the horizontal plate 2. Two sliders 9 are slidably installed inside the fixing post 8. Two bolts 11 are rotatably installed on both sides of the two sliders 9. A locking block 12 is threaded onto the outer surface of the bolt 11.

[0026] By rotating bolt 11, bolt 11 engages with locking block 12. The rotation of bolt 11 allows locking block 12 to engage with or disengage from fixed column 8. When diagonal brace 7 rotates with adjustment block 3, it slides on the surface of slide rod 10. The locking block 12 and the diagonal brace 7 work together to make the diagonal brace 7 more secure. Compared with traditional devices, this mechanism combines the engagement of blocking block 5 with fixed block 13 and the engagement of locking block 12 with fixed column 8, forming a double locking system. This design ensures that diagonal brace 7 can be firmly fixed after being adjusted to the appropriate position, effectively preventing displacement caused by external force or vibration, thereby improving the overall stability of the support structure.

[0027] like Figures 1 to 8 As shown, a slide rod 10 is fixedly installed inside the fixed column 8, and two sliders 9 are slidably sleeved on the outer surface of the slide rod 10; a diagonal support column 7 is hinged to the top of the adjusting block 3, and the other end of the diagonal support column 7 is hinged to the two sliders 9 respectively.

[0028] With the sliding rod 10 installed, when the diagonal support column 7 rotates on top of the adjusting block 3, the diagonal support column 7 can rise or fall smoothly according to the guidance and support of the sliding rod 10. With the diagonal support column 7 installed, the diagonal support column 7 is hinged to the slider 9 and the adjusting block 3, so that the whole structure can be flexibly adjusted.

[0029] like Figures 1 to 8 As shown, both sliders 9 are slidably mounted on the surface of the diagonal support column 7, and the locking block 12 is engaged with the diagonal support column 7; a fixing block 13 is fixedly mounted on the top of the horizontal plate 2, and the fixing block 13 is engaged with the blocking block 5; a torsion spring 6 is fixedly mounted inside the adjusting block 3, and the torsion spring 6 is fixedly sleeved on the outer surface of the rotating rod 4.

[0030] The secondary fixation is achieved by the locking block 12 engaging with the diagonal brace 7, making the entire structure more stable and robust. With the fixed block 13, when the adjusting block 3 slides on the top of the horizontal plate 2, the locking block 5 engages with the fixed block 13 to achieve stable fixation, giving the entire structure good support. With the torsion spring 6, the elastic potential energy of the torsion spring 6 allows the rotating rod 4 to return to its initial state after manual rotation, thereby achieving a firm engagement between the blocking block 5 and the fixed block 13.

[0031] The working principle and usage process of this utility model: The operator rotates the rotating rod 4, which drives the blocking block 5 to rotate. The rotation of the rotating rod 4 drives the torsion spring 6 to rotate inside the adjusting block 3. When the blocking block 5 rotates to the point where it is no longer engaged with the fixed block 13, the adjusting block 3 is pushed, and the adjusting block 3 slides on the top of the horizontal plate 2. When it moves to the appropriate position, the force applied to the rotating rod 4 is released, and the torsion spring 6 returns to its elastic deformation, driving the rotating rod 4 to rotate. The rotating rod 4 drives the blocking block 5 to rotate, so that the blocking block 5 engages with the fixed block 13, thereby fixing the adjusting block 3. The operator rotates the rotating rod 4, through a series of... The cooperation of the components prevents the blocking block 5 from engaging with the fixing block 13. At the same time, rotating the bolt 11 causes the locking block 12 to move on the outer surface of the bolt 11. When the locking block 12 is not engaged with the fixing post 8, the adjusting block 3 is pushed, causing the adjusting block 3 to slide on the top of the horizontal plate 2, which in turn causes the diagonal support column 7 to rotate around the adjusting block 3. The diagonal support column 7 slides on the outer surface of the slide rod 10. When it slides to the appropriate position, the force applied to the adjusting block 3 is released, causing the blocking block 5 to engage with the fixing block 13. Rotating the bolt 11 causes the locking block 12 to engage with the fixing post 8.
