Description

Technical Field

[0001] This application relates to the field of foundation pit support technology in building engineering, and in particular to a corner support structure for foundation pits. Background Technology

[0002] Excavation pit support is a crucial step in ensuring construction safety and the stability of the surrounding environment. The corners of an excavation pit, as the intersection of two sides, experience complex stress conditions and are prone to deformation and collapse. Therefore, specialized support structures are required to enhance corner stability. Existing excavation pit corner support structures typically include components such as support plates, designed to provide effective support by ensuring a close fit between the support plates and the two sides of the pit corner.

[0003] However, in actual construction, due to factors such as complex geological conditions, limitations in the precision of excavation equipment, and construction techniques, the plane of the corner area of ​​the foundation pit may be uneven. However, most of the existing support plates are flat structures, which makes it difficult to adapt to such uneven planes. As a result, some areas of the support plate cannot be tightly attached to the two sides of the corner of the foundation pit, resulting in gaps between the support plate and the sides of the foundation pit. This situation not only causes uneven distribution of support force and reduces the overall support effect of the corner support structure, but may also cause local stress concentration, increasing the risk of deformation or even collapse of the corner of the foundation pit, posing a threat to construction safety and project quality. Utility Model Content

[0004] The purpose of this application is to provide a corner support structure for foundation pits. By setting a corner support frame composed of multiple support components, the stability of the foundation pit corner can be greatly improved. At the same time, the angle adjustment component in each support component adjusts the angle of the first support plate and the second support plate, so that the outer sides of the two plates are closely attached to the two sides of the foundation pit corner, avoiding the formation of gaps. This allows the vertically arrayed support components to flexibly adapt to the uneven longitudinal surface of the foundation pit corner, and solves the problems raised in the background art.

[0005] This application provides a corner support structure for a foundation pit, employing the following technical solution: It includes a corner support frame, which is composed of multiple vertically arrayed support components. Each support component includes a support column. A first support plate and a second support plate are rotatably connected to the outer side of the support column. Guide rails are fixedly connected to the outer sides of both the first and second support plates. An angle adjustment component is provided between the first and second support plates. A docking block is fixedly connected to the bottom surface of the support column. A docking hole is opened on the upper side of the support column. A first insertion hole is opened on the outer side of the support column. The inner wall of the first insertion hole communicates with the inner wall of the docking hole. A movable cavity is opened inside the docking block. A second insertion hole is opened on the outer side of the movable cavity. A locking rod assembly is provided on the outer side of the support column. The locking rod assembly includes an insertion post. Two symmetrical protrusions are fixedly connected to the outer side of the insertion post. The outer sides of the insertion post and the protrusions are inserted into the inner wall of the second insertion hole.

[0006] By adopting the above technical solution and setting up a corner support frame composed of multiple support components, the stability of the foundation pit corner can be significantly improved. Each support component consists of a support column, a first support plate, and a second support plate. With the help of the angle adjustment component, the angles of the first and second support plates can be adjusted to ensure that their outer sides fit tightly against the two sides of the foundation pit corner, avoiding gaps. This allows the vertically arrayed support components to flexibly adapt to the uneven longitudinal surface of the foundation pit corner, resulting in a uniform distribution of support force and improving the overall support effect of the corner support structure. At the same time, the design of the docking block and docking hole facilitates the rapid splicing of the support components. In addition, the clamping rod component can firmly connect adjacent support columns through the cooperation of the insertion column and the protrusion block with the second insertion hole, enhancing the overall structural stability.

[0007] Preferably, the first support plate and the second support plate are arranged symmetrically.

[0008] By adopting the above technical solution, the first and second support plates can provide support to the two sides of the corner of the foundation pit after the angle is adjusted, so that the support force is more evenly distributed, avoids local stress concentration, and further improves the corner support effect.

[0009] Preferably, the inner wall dimensions of the mating hole are adapted to the outer dimensions of the mating block.

[0010] By adopting the above technical solution, the sizes of the docking holes and docking blocks are matched, ensuring the tightness and stability of the connection between the support components, effectively preventing misalignment of the support components, and ensuring the reliability of the overall support structure.

[0011] Preferably, the shape of the insert post and the protrusion is adapted to the inner wall shape of the second insertion hole, and the inner wall of the second insertion hole is horizontally arranged relative to the position of the protrusion.

[0012] By adopting the above technical solution, the shape of the insert post, the protrusion block and the second insertion hole are adapted to each other. With the specific inner wall setting of the second insertion hole, the clamping rod assembly can be accurately positioned and inserted when connecting the support post. After that, the clamping rod assembly is rotated so that the insert post and the protrusion block are in a vertical state, so that the clamping rod assembly cannot be pulled out. This can enhance the stability of the connection between the support posts and improve the overall strength of the support structure.

[0013] Preferably, a counterweight is fixedly connected to the outer side of the insertion post, and a rotating handle is fixedly connected to one end of the insertion post.

[0014] By adopting the above technical solution, the counterweight can make the insert rotate on its own under the action of gravity, so that the insert and the protrusion rotate on their own in a vertical state under the drive of the counterweight, thereby preventing the clamping rod assembly from disengaging from the interior of the docking block, thus enhancing the stability of the connection between the support columns.

[0015] Preferably, two second arc-shaped support rods are fixedly connected to the outer side of the second support plate, and two first arc-shaped support rods are fixedly connected to the outer side of the first support plate. The second arc-shaped support rods and the first arc-shaped support rods are closely fitted together. Sliding grooves are provided on the inner sides of both the first and second arc-shaped support rods. Bolts are provided on the inner sides of both the first and second arc-shaped support rods. The outer sides of the bolts are slidably connected to the inner wall of the sliding grooves. The first arc-shaped support rods and the second arc-shaped support rods are fixedly connected by bolts.

[0016] By adopting the above technical solution, the first arc-shaped support rod and the second arc-shaped support rod are fixedly connected by bolts, which can enhance the structural strength and stability of the first support plate and the second support plate, enabling them to better withstand pressure when they fit against the side of the corner of the foundation pit, and improve the support effect.

[0017] Preferably, the angle adjustment assembly includes an internally threaded sleeve, the inner side of which is threadedly connected to two symmetrical lead screws. The ends of the two lead screws away from the internally threaded sleeve are rotatably connected to connecting seats. The outer sides of the two connecting seats are hinged to sliding seats, and the outer sides of the sliding seats are slidably connected to the inner wall of the guide rail.

[0018] By adopting the above technical solution, the internal threaded sleeve is threadedly connected to two lead screws. The connecting seat at the end of the lead screw is hinged to the sliding seat and slidably connected to the inner wall of the guide rail. Rotating the internal threaded sleeve can drive the lead screw to move, thereby adjusting the angle between the first support plate and the second support plate to adapt to different uneven planes at the corner of the foundation pit, so that the two can better fit the side.

[0019] Preferably, a protective sleeve is fixedly connected to the outer side of the internally threaded sleeve, the surface of the protective sleeve is provided with anti-slip texture, and the protective sleeve is made of rubber.

[0020] By adopting the above technical solution, the protective sleeve is made of rubber and has anti-slip texture on the surface, which can increase the friction when the operator rotates, making the angle adjustment operation more comfortable and convenient, and the rubber material has a certain degree of cushioning and durability.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This type of foundation pit corner support structure uses a corner support frame composed of multiple vertically arrayed support components. It features independently rotatable first and second support plates, and angle adjustment components that flexibly adjust the angles of these plates to adapt to the complex and uneven surface of the foundation pit corner. This ensures a tight fit between the plates and the pit side, preventing gaps. Simultaneously, the connecting blocks and holes enable rapid vertical stacking of multiple support components. Furthermore, the protruding block of the locking rod component and the second insertion hole form a gravity self-locking mechanism, ensuring a stable connection between the multiple support components. This enhances the overall support effect of the corner support structure, reduces the risk of deformation or even collapse at the foundation pit corner, and significantly improves the safety and adaptability of the support.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A corner support structure for a foundation pit, please refer to... Figure 1 , Figure 2 and Figure 5 The system includes a corner support frame 1, which is composed of multiple vertically arrayed support components. This corner support frame 1, consisting of multiple vertically arrayed support components, can significantly improve the stability of the pit corner. Each support component includes a support column 2, with a first support plate 3 and a second support plate 4 rotatably connected to the outer side of the support column 2. The first support plate 3 and the second support plate 4 are symmetrically arranged. After adjusting their angles, the first support plate 3 and the second support plate 4 can provide support to both sides of the pit corner, resulting in a more uniform distribution of support force and preventing localized stress. Force concentration further improves the corner support effect. Guide rails 5 are fixedly connected to the outer sides of the first support plate 3 and the second support plate 4. An angle adjustment component 6 is set between the first support plate 3 and the second support plate 4. A docking block 7 is fixedly connected to the bottom surface of the support column 2. A docking hole 8 is opened on the upper side of the support column 2. The inner wall size of the docking hole 8 is adapted to the outer size of the docking block 7. The size adaptation between the docking hole 8 and the docking block 7 ensures the tightness and stability of the connection between the support components, effectively prevents the misalignment of the support components, and ensures the reliability of the overall support structure.

[0026] Please refer to Figure 2 , Figure 2 and Figure 5 The support column 2 has a first insertion hole 10 on its outer side, and the inner wall of the first insertion hole 10 is connected to the inner wall of the docking hole 8. The docking block 7 has a movable cavity 12 inside, and a second insertion hole 11 is opened on the outer side of the movable cavity 12. A locking rod assembly 9 is provided on the outer side of the support column 2. The locking rod assembly 9 includes an insertion post 901, and two symmetrical protrusions 902 are fixedly connected to the outer side of the insertion post 901. The outer sides of the insertion post 901 and the protrusions 902 are inserted into the inner wall of the second insertion hole 11. Two second arc-shaped support rods 14 are fixedly connected to the outer side of the second support plate 4. Two first arc-shaped support rods 13 are fixedly connected to the outer side of the first support plate 3. The arc-shaped support rod 14 and the first arc-shaped support rod 13 are tightly fitted together. The inner sides of both the first arc-shaped support rod 13 and the second arc-shaped support rod 14 are provided with sliding grooves. Bolts are provided on the inner sides of both the first arc-shaped support rod 13 and the second arc-shaped support rod 14. The outer sides of the bolts are slidably connected to the inner wall of the sliding grooves. The first arc-shaped support rod 13 and the second arc-shaped support rod 14 are fixedly connected by bolts. The fixed connection of the first arc-shaped support rod 13 and the second arc-shaped support rod 14 by bolts can enhance the structural strength and stability of the first support plate 3 and the second support plate 4, so that they can better withstand pressure when they fit against the side of the corner of the foundation pit, thereby improving the support effect.

[0027] Example 2: A corner support structure for a foundation pit, please refer to... Figure 2 and Figure 5The shapes of the insertion post 901 and the protrusion 902 are adapted to the inner wall shape of the second insertion hole 11. The inner wall of the second insertion hole 11 is horizontal relative to the position of the protrusion 902. The adapted shapes of the insertion post 901 and the protrusion 902 to the second insertion hole 11, combined with the specific inner wall setting of the second insertion hole 11, enable the locking rod assembly 9 to be accurately positioned and inserted when connecting to the support post 2. Afterwards, rotating the locking rod assembly 9 makes the insertion post 901 and the protrusion 902 vertical, thereby preventing the locking rod assembly 9 from being pulled out. This enhances the stability of the connection between the support columns 2 and improves the overall strength of the support structure. A counterweight 903 is fixedly connected to the outside of the insert column 901, and a rotating handle 904 is fixedly connected to one end of the insert column 901. The counterweight 903 allows the insert column 901 to rotate on its own under the action of gravity, so that the insert column 901 and the protrusion 902 rotate on their own and are in a vertical state under the action of the counterweight 903. This prevents the clamping rod assembly 9 from disengaging from the interior of the docking block 7, thereby enhancing the stability of the connection between the support columns 2.

[0028] Please refer to Figure 2 and Figure 4 The angle adjustment assembly 6 includes an internally threaded sleeve 601. Two symmetrical lead screws 602 are threadedly connected to the inner side of the internally threaded sleeve 601. A connecting seat 603 is rotatably connected to the end of each lead screw 602 away from the internally threaded sleeve 601. A sliding seat 604 is hinged to the outer side of each connecting seat 603, and the outer side of the sliding seat 604 is slidably connected to the inner wall of the guide rail 5. The internally threaded sleeve 601 is threadedly connected to the two lead screws 602. The connecting seat 603 at the end of the lead screw 602 is hinged to the sliding seat 604 and slidably connected to the inner wall of the guide rail 5. Rotating the internally threaded sleeve 601... 1 can drive the lead screw 602 to move, thereby adjusting the angle between the first support plate 3 and the second support plate 4 to adapt to different uneven surfaces at the corner of the foundation pit, so that the two can better fit the side. The outer side of the internal threaded sleeve 601 is fixedly connected to a protective sleeve 605. The surface of the protective sleeve 605 is provided with anti-slip texture. The protective sleeve 605 is made of rubber. The above-mentioned protective sleeve 605 is made of rubber and has anti-slip texture on the surface, which can increase the friction when the operator rotates, making the angle adjustment operation more comfortable and convenient. In addition, the rubber material has a certain buffer and durability.

[0029] The implementation principle of this application embodiment is as follows: First, the number of support components is determined according to the depth of the foundation pit. Then, the support column 2 of each support component is inserted into the docking hole 8 of the adjacent support column 2 through the bottom docking block 7. After that, the insertion post 901 of the clamping rod assembly 9 is inserted into the second insertion hole 11 of the docking block 7. Under the action of gravity, the counterweight block 903 drives the insertion post 901 to rotate, so that the protrusion block 902 is vertical and forms a locking position with the horizontal inner wall of the second insertion hole 11, realizing a quick and stable connection. Then, when the internal threaded sleeve 601 is rotated, the two threads connected to it... The lead screw 602 moves synchronously to both sides, thereby driving the sliding seat 604 to slide within the guide rail 5, thus changing the angle between the first support plate 3 and the second support plate 4, so that the two support plates are tightly attached to the two sides of the corner of the pit. At this time, the rotation of the first support plate 3 and the second support plate 4 drives the first arc-shaped support rod 13 and the second arc-shaped support rod 14 to move synchronously. After the angle of the first support plate 3 and the second support plate 4 is adjusted, the two arc-shaped support rods are locked by bolts to form a support structure, which enhances the deformation resistance of the support component and evenly distributes the support force.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
