Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a foundation pit support frame. Background Art

[0002] The foundation pit plays an important role in water conservancy projects. It is a temporary project that mainly provides a space so that the foundation masonry work can be carried out according to the designated position in the design. Among them, the foundation pit support is very important. The main function of the foundation pit support is to support the soil wall and improve the stability of the foundation pit.

[0003] A foundation pit support device mentioned in the existing Chinese public patent (authorization announcement number: CN219886863U) can adjust the inclination of the support plate, so that the support plate can protect foundation pits with different slopes, effectively solving the problem that the existing support device has a relatively simple structure and is inconvenient to reinforce foundation pits of different specifications.

[0004] In the existing support of foundation pits, the inner wall of the foundation pit is mostly supported by support plates, and the two ends of the support plates are connected to the inner bottom wall of the foundation pit through support columns. Although the structure is simple and the construction is convenient, due to the complex soil conditions at the bottom of the foundation pit, there may be unstable soils such as soft soil and wet soil, which may lead to insufficient stability of the support columns, thereby affecting the safety of the entire foundation pit. Utility Model Content

[0005] The purpose of the present application is to provide a foundation pit support frame to solve the problem of unstable soils such as soft soil and wet soil, which may lead to insufficient stability of the support columns.

[0008] By adopting the above technical solution, it is first necessary to fix the base on the inner wall of the foundation pit, then weld the support column on the top of the base, then weld the connecting plate on the top of the support column, and finally weld the crossbeam on the top of the connecting plate. The two ends of the crossbeam are fixed to the inner wall of the foundation pit, thereby completing the support of the foundation pit. The stability of the crossbeam is made higher by the reinforcement mechanism, and the support column is supported by the support mechanism.

[0012] By adopting the above technical solution, the angle of the telescopic sleeve is fixed by fastener 1, thereby reducing the risk of displacement of the telescopic sleeve during support.

[0013] Furthermore, a long hole is opened on one side of the telescopic sleeve, and a second fastener is fixedly connected to one side of the telescopic sleeve rod, and the second fastener is slidably connected to the long hole.

[0014] By adopting the above technical solution, the telescopic sleeve rod can be moved inside the telescopic sleeve, and the position of the fastener 2 can be adjusted according to actual needs to meet different requirements.

[0015] Furthermore, the support seat is configured to be trapezoidal.

[0016] By adopting the above technical solution, the contact surface between the support seat and the bottom wall of the foundation pit is enlarged.

[0019] Furthermore, the reinforcement mechanism includes a plurality of through holes fixedly opened inside the crossbeam, a first diagonal brace is arranged inside the through hole, a second diagonal brace is arranged on one side inside the through hole, and the first diagonal brace and the second diagonal brace are arranged in an X shape.

[0020] By adopting the above technical solution, diagonal brace one and diagonal brace two can effectively disperse the pressure and provide strong support for foundation pit construction.

[0021] Furthermore, a reinforcing plate 1 is fixedly connected to the top of the connecting plate, the top of the reinforcing plate 1 is fixedly connected to the cross beam, and reinforcing plates 2 are symmetrically fixedly connected to both sides of the cross beam, and one end of the reinforcing plate 2 away from the cross beam is fixed to the inner wall of the foundation pit.

[0022] By adopting the above technical solution, the first reinforcement plate is fixedly connected to the cross beam, so that the stability between the connecting plate and the cross beam is enhanced. By welding the second reinforcement plate to the foundation pit, the foundation pit, the cross beam and the second reinforcement plate are arranged in a triangle, which further improves the stability of the cross beam.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In this application, when it is necessary to support the support column, the telescopic sleeve is pulled to drive the support seat to move, so that the support seat is in conflict with the inner bottom wall of the foundation pit, thereby effectively supporting the support column. The support method is simple and practical, which can ensure the stability and safety of the support column and provide good conditions for subsequent engineering construction. At the same time, it also has a certain degree of flexibility. The angle of the telescopic sleeve and the length of the telescopic sleeve can be adjusted according to actual needs to meet the support requirements in different scenarios.

[0025] 2. In the present application, when the foundation pit exerts pressure on the beam, the inner wall of the through hole is supported in an X shape by using diagonal braces 1 and 2, which can effectively disperse the pressure so that the beam can remain stable when subjected to greater pressure, providing strong support for the foundation pit construction, thereby reducing the risk of deformation of the beam.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a foundation pit support frame.

[0034] Reference Figure 1 and Figure 2 A foundation pit support frame includes a crossbeam 1, both ends of the crossbeam 1 are fixed to the inner wall of the foundation pit, connecting plates 2 are welded on both sides of the bottom of the crossbeam 1, supporting columns 3 are welded on both sides of the bottom of the connecting plate 2, and a base 4 is welded at the bottom end of the support column 3. A reinforcement mechanism is provided on the inner wall of the crossbeam 1, and a supporting mechanism is provided on the outer surface of the base 4.

[0035] In water conservancy projects, foundation pit excavation is a key construction step. After the foundation pit excavation is completed, a supporting mechanism is needed to support the foundation pit. When the foundation pit needs to be supported, first, the inner wall of the foundation pit needs to be fixed with a base 4, and then the support column 3 is welded on the top of the base 4, and then the connecting plate 2 is welded on the top of the support column 3, and finally the crossbeam 1 is welded on the top of the connecting plate 2. The function of the crossbeam 1 is to provide horizontal support force to resist the horizontal pressure inside and outside the foundation pit, and the length and width of the crossbeam 1 should be determined according to the size and depth of the foundation pit. The two ends of the crossbeam 1 are fixed to the inner wall of the foundation pit, thereby completing the support of the foundation pit. During the support process, the reinforcement mechanism is used to make the crossbeam 1 more stable, thereby improving the stability of the entire support structure. At the same time, the support column 3 is supported by the supporting mechanism to provide additional support force for the support column 3.

[0036] Reference Figure 3 and Figure 4 The supporting mechanism includes a fixed block 5 fixedly connected to the outer surface of the supporting column 3, the four sides of the fixed block 5 are fixedly connected to a rotating seat 6, the interior of the rotating seat 6 is rotatably connected to a telescopic sleeve 7, the interior of the telescopic sleeve 7 is slidably connected to a telescopic sleeve rod 8, and the bottom end of the telescopic sleeve rod 8 is fixedly connected to a supporting seat 9.

[0037] Among them, a C-shaped hole 10 is opened on one side of the rotating seat 6, and a fastener 11 is fixedly connected to one side of the telescopic sleeve 7. The fastener 11 is slidably connected to the C-shaped hole 10; the fastener 11 is a combined structural component of a screw and a nut threadedly connected, which is the prior art.

[0038] In addition, a long hole 12 is provided on one side of the telescopic sleeve 7, and a second fastener 13 is fixedly connected to one side of the telescopic sleeve rod 8. The second fastener 13 is slidably connected to the long hole 12, and the second fastener 13 is also a combined structural member of a screw and a nut threadedly connected, which is a prior art. The second fastener 13 can rotate relative to the long hole 12, so that after the second fastener 13 is loosened, the telescopic sleeve rod 8 can rotate relative to the telescopic sleeve 7.

[0039] Furthermore, the support seat 9 is arranged in a trapezoidal shape.

[0040] In addition, a plurality of friction strips 14 are fixedly connected to the bottom of the support seat 9 at equal intervals.

[0041] When it is necessary to support the support column 3, the staff first rotates the telescopic sleeve 7. After rotating to a suitable angle, the staff pulls the telescopic sleeve rod 8 to slide inside the telescopic sleeve 7. After the telescopic sleeve rod 8 moves, it drives the support seat 9 to move, so that the support seat 9 conflicts with the inner bottom wall of the foundation pit, thereby effectively supporting the support column 3. The supporting method is simple and practical, and can ensure the stability and safety of the support column 3, providing good conditions for subsequent engineering construction. At the same time, it also has a certain degree of flexibility. The angle of the telescopic sleeve 7 and the length of the telescopic sleeve rod 8 can be adjusted according to actual needs to meet the support requirements in different scenarios. When the telescopic sleeve 7 rotates inside the rotating seat 6, the telescopic sleeve 7 drives the fastener 11 to slide inside the C-shaped hole 10. When the angle is appropriate, the staff rotates the fastener 11 to make the telescopic sleeve 7 The angle is fixed, reducing the risk of displacement during support of the telescopic sleeve 7. When the telescopic sleeve rod 8 moves, the telescopic sleeve rod 8 drives the fastener 2 13 to slide inside the long hole 12. After sliding to a suitable position, the staff rotates the fastener 2 13 to fix the position of the telescopic sleeve rod 8, thereby improving the stability of the telescopic sleeve rod 8 during support. At the same time, it also has a certain flexibility. The position of the fastener 2 13 can be adjusted according to actual needs to meet the support requirements in different scenarios. The support seat 9 is set to a trapezoidal shape, so that the contact area between the support seat 9 and the bottom wall of the foundation pit becomes larger, making it more stable when under pressure. At the same time, a number of friction strips 14 are provided at the bottom of the support seat 9 to improve the friction between the support seat 9 and the bottom wall of the foundation pit, thereby further ensuring the stability and safety of the support column 3, and providing good conditions for subsequent engineering construction.

[0042] Reference Figure 1 and Figure 2 The reinforcement mechanism includes a plurality of through holes 15 fixedly opened inside the cross beam 1, a diagonal brace 16 is arranged inside the through hole 15, a diagonal brace 2 17 is arranged on one side inside the through hole 15, and the diagonal brace 16 and the diagonal brace 2 17 are arranged in an X shape.

[0043] Among them, the top of the connecting plate 2 is fixedly connected with a reinforcing plate 18, the top of the reinforcing plate 18 is fixedly connected to the beam 1, and the two sides of the beam 1 are symmetrically fixedly connected with reinforcing plates 2 19, and the end of the reinforcing plate 2 19 away from the beam 1 is fixed to the inner wall of the foundation pit.

[0044] When the foundation pit exerts pressure on the beam 1, the inner wall of the through hole 15 is supported in an X shape by the diagonal brace 1 16 and the diagonal brace 2 17, which can effectively disperse the pressure, so that the beam 1 can still remain stable when subjected to greater pressure, providing strong support for the foundation pit construction, thereby reducing the risk of deformation of the beam 1, and the reinforcement plate 1 18 is fixedly connected to the beam 1 to make the stability between the connecting plate 2 and the beam 1 stronger, and then the reinforcement plate 2 19 is welded to the foundation pit, so that the foundation pit, the beam 1 and the reinforcement plate 2 19 are arranged in a triangle, further improving the stability of the beam 1.

[0045] Working principle: When it is necessary to support the foundation pit, first, the base 4 needs to be fixed to the inner wall of the foundation pit, and then the support column 3 is welded on the top of the base 4, and then the connecting plate 2 is welded on the top of the support column 3, and finally the crossbeam 1 is welded on the top of the connecting plate 2. The two ends of the crossbeam 1 are fixed to the inner wall of the foundation pit, thereby completing the support of the foundation pit. The staff rotates the telescopic sleeve 7. After rotating to a suitable angle, the staff pulls the telescopic sleeve 8 to slide inside the telescopic sleeve 7, and the telescopic sleeve 8 moves and drives the support seat 9 to move, so that the support seat 9 is in conflict with the inner bottom wall of the foundation pit, thereby effectively supporting the support column 3.

[0046] The telescopic sleeve 7 drives the fastener 11 to slide inside the C-shaped hole 10. When the angle is appropriate, the staff rotates the fastener 11 to fix the angle of the telescopic sleeve 7, reducing the risk of displacement of the telescopic sleeve 7 during support. The staff rotates the fastener 2 13 to fix the position of the telescopic sleeve rod 8, thereby improving the stability of the telescopic sleeve rod 8 during support. The inner wall of the through hole 15 is supported in an X shape by the diagonal brace 1 16 and the diagonal brace 2 17, which can effectively disperse the pressure, so that the beam 1 can still remain stable when subjected to greater pressure, providing strong support for the foundation pit construction, thereby reducing the risk of deformation of the beam 1. The reinforcing plate 18 is fixedly connected to the beam 1, so that the stability between the connecting plate 2 and the beam 1 is stronger.
