Description

Technical Field

[0001] This application relates to the field of building equipment, and in particular to a building support structure. Background Technology

[0002] Support structures are structures used to reinforce and protect the sidewalls and surrounding environment of underground structures to ensure the safety of underground construction and the safety of the surrounding environment. When building a house, a foundation pit needs to be excavated on the ground. During and after excavation, the sidewalls of the pit need to be supported. Common support structures include retaining plates, which contact the sidewalls of the pit to provide support.

[0003] When it rains or groundwater surges, the flowing water may wash away the soil on the surface of the pit sidewall. The commonly used protective panels are fixed in position, which means that the protective panels cannot fit well with the pit sidewall, resulting in poor support effect of the support structure on the pit sidewall. Summary of the Invention

[0004] In order to improve the support effect of the support structure on the sidewall of the foundation pit, this application provides a building support structure.

[0005] The technical solution for a building support structure provided in this application is as follows:

[0006] A building support structure includes a base frame and a protective plate slidably connected to the upper surface of the base frame. An installation groove is provided on one side wall of the base frame, and the protective plate is located on the side of the base frame near the groove opening. An adjusting component is provided on the base frame to push the protective plate to move. A fixing component is also provided on the base frame to fix the base frame and the bottom surface of the foundation pit.

[0007] The base frame is equipped with a drive assembly that pushes the guard plate toward the corresponding side wall of the pit. The drive assembly includes a drive rod located on one side of the guard plate and rotatably connected to the upper surface of the base frame. The rotation point of the drive rod is located in the middle of itself.

[0008] A protrusion is hinged to one end of the drive rod near the guard plate. The protrusion slides along the length of the guard plate. A limiting spring is fixedly connected to the protrusion. The end of the limiting spring away from the protrusion is fixedly connected to the guard plate. The limiting spring creates an angle between the drive rod and the guard plate.

[0009] The base frame is also equipped with a power unit that drives the drive rod to rotate.

[0010] By adopting the above technical solution, when it is necessary to support the foundation pit, the operator first places the base frame in a suitable position so that the protective plate contacts the corresponding side wall of the foundation pit. Then, the base frame is fixed to the bottom surface of the foundation pit using fasteners. Next, the protective plate is pressed against the adjusting parts to maintain its position, thereby supporting the side wall of the foundation pit. In the initial state, the limiting spring limits the protrusion, so that the drive rod is tilted. When water seeps out from the side wall of the foundation pit, the power component works to drive the drive rod to rotate. The drive rod rotates and pushes the protective plate to move, thus pressing it against the side wall of the foundation pit. The protective plate can better support the side wall of the foundation pit, improving the support effect of the support structure on the side wall of the foundation pit.

[0011] Optionally, multiple sliding plates are fixedly connected to the lower surface of the guard plate, and the base frame is also provided with sliding grooves corresponding to the sliding plates. The length direction of the sliding grooves is set along the moving direction of the guard plate, and each sliding plate is slidably inserted into the corresponding sliding groove.

[0012] By adopting the above technical solution, the slide plate and the slide groove cooperate to make the guard plate and the base frame slide together.

[0013] Optionally, the drive assembly further includes a long strip-shaped mating ring fixedly connected to the end of the drive rod away from the protrusion. The length direction of the mating ring is set along the height direction of the guard plate, and a crossbar passes through the mating ring. The power assembly drives the crossbar to move along the sliding direction of the guard plate.

[0014] By adopting the above technical solution, when the power component is working, the power component pushes the crossbar to move away from the guard plate. The movement of the crossbar drives the mating ring to move, and the movement of the mating ring can drive the drive rod to rotate.

[0015] Optionally, the power assembly includes a water collection hopper located in the mounting slot. Several vertical rods are fixedly connected to the crossbar. The vertical rods are slidably inserted into the base frame. The vertical rods are fixedly connected to the water collection hopper. The water collection hopper is slidably connected to the base frame. Several return springs are fixedly connected to the bottom wall of the mounting slot of the water collection hopper. The return springs are fixedly connected to the water collection hopper. The sliding trajectory of the water collection hopper gradually slopes upward from the bottom of the mounting slot towards the opening of the mounting slot.

[0016] A sponge block is provided above the water collection hopper, with one side of the sponge block protruding from the mounting groove. A water squeezing component for squeezing the sponge is also provided in the mounting groove.

[0017] By adopting the above technical solution, when water seeps out from the side wall of the foundation pit, the water falls along the protective plate onto the sponge block, which stores the water. When the water in the sponge block reaches a certain amount, the water squeezing component squeezes the water out of the sponge block. The sponge block can absorb subsequent water, and the squeezed water falls into the water collection hopper for collection. As the water in the water collection hopper gradually increases, the water collection hopper slides towards the bottom of the installation groove by its own gravity. During this process, the water collection hopper compresses the return spring. The movement of the water collection hopper drives the vertical rod and horizontal rod to move, thereby driving the drive rod to rotate.

[0018] Optionally, guide rails are fixedly connected to the two opposite side walls of the mounting groove. The end of the guide rail near the opening of the mounting groove is higher than the end of the guide rail near the bottom of the mounting groove. Guide blocks corresponding to the guide rails are fixedly connected to the water collection hopper, and each guide block is slidably inserted into the corresponding guide rail.

[0019] By adopting the above technical solution, the guide rail and guide block cooperate to make the water collection hopper and the base frame slide together.

[0020] Optionally, the dewatering component includes multiple connecting rods vertically fixed to the lower surface of the guard plate, a receiving bucket slidably inserted into the multiple connecting rods, and a support spring sleeved on the connecting rods.

[0021] The lower end of the connecting rod contacts the bottom wall of the mounting groove. The support spring is located below the receiving hopper, and the upper end of the support spring contacts the receiving hopper. The receiving hopper is open on the side near the bottom wall of the mounting groove and at the top. The sponge block is placed in the receiving hopper.

[0022] A dewatering plate is slidably connected inside the receiving hopper. The dewatering plate is located between the connecting rod and the corresponding side wall of the receiving hopper. The sponge block is located on the side of the dewatering plate away from the connecting rod. A push rod is hinged to the connecting rod and is hinged to the dewatering plate. The end of the push rod near the dewatering plate is higher than the end of the push rod near the connecting rod.

[0023] By adopting the above technical solution, when the water in the sponge block gradually increases, the sponge block moves downward by pressing the receiving hopper. The moving receiving hopper compresses the supporting spring. The moving receiving hopper also drives the squeezing plate and the corresponding end of the push rod to move downward. At the same time, the push rod rotates and pushes the squeezing plate to move closer to the corresponding side wall of the hopper. The squeezing plate and the corresponding side wall of the hopper cooperate to squeeze the sponge block, causing the water in the sponge block to flow out.

[0024] Optionally, one side of the protective plate protrudes from the base frame, and the lower surface of the protective plate protrudes downward from the position of the base frame to form a drainage section, which contacts the sponge block.

[0025] By adopting the above technical solution, the water between the protective plate and the side wall can flow to the sponge block more effectively through the drainage part.

[0026] Optionally, a plurality of guide grooves are provided on the side wall of the protective plate near the mounting groove opening, and the length direction of the guide grooves is set along the height direction of the protective plate.

[0027] By adopting the above technical solution, the water between the protective plate and the side wall can flow to the sponge block better through the guide channel.

[0028] Optionally, the adjusting component includes several uprights fixedly connected to the upper surface of the base frame and lead screws corresponding to the uprights. The length direction of the lead screws is consistent with the sliding direction of the guard plate, and the lead screws pass through the uprights and are threaded to the uprights.

[0029] By adopting the above technical solution, after the protective plate is attached to the side wall of the pit, the screw is rotated so that the end of the screw contacts the protective plate, thereby limiting the position of the protective plate and enabling the protective plate to support the side wall of the pit.

[0030] Optionally, the fixing component includes a support ring sleeved on the lead screw, an upper rod fixedly connected to the support ring, a lower rod inserted into the lower end of the upper rod, the upper rod and the lower rod being threadedly connected, and the lower rod passing through the base frame.

[0031] By adopting the above technical solution, after the base frame is placed, the lower rod is rotated until it is inserted into the bottom of the pit. At the same time, the support ring supports the lead screw, reducing the possibility of the lead screw bending. When the base frame needs to be moved, the lower rod is rotated. Since the support ring is sleeved on the lead screw, the operator does not need to manually fix the upper rod. When the lower rod moves into the base frame, the base frame is released from the bottom of the pit, and the operator can move the base frame.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting up a base frame, guard plate, adjusting components, fixing components, drive rod, protrusion, limit spring, and power assembly, the support effect of the support structure on the sidewall of the foundation pit is improved;

[0034] 2. By setting up a water collection hopper, a return spring, a sponge block, and a water squeezing component, the movement of the water collection hopper drives the vertical and horizontal rods to move, thereby driving the drive rod to rotate;

[0035] 3. By setting up connecting rods, receiving buckets, support springs, squeezing plates, and push rods, the sponge blocks can be squeezed. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0042] This application discloses a building support structure. (Refer to...) Figure 1 and Figure 2 The system includes a base frame 1 placed on the bottom wall of the foundation pit. An installation groove 11 is provided on the side wall of the base frame 1 corresponding to the side wall of the foundation pit. A protective plate 2 is slidably connected to the upper surface of the base frame 1. The protective plate 2 is located on the side of the base frame 1 near the opening of the installation groove 11. The protective plate 2 is perpendicular to the base frame 1. The side of the protective plate 2 near the opening of the installation groove 11 protrudes from the base frame 1, and the lower surface of the protective plate 2 protrudes downward from the position of the base frame 1 to form a drainage part 21. The lower surface of the drainage part 21 is not higher than the upper wall of the installation groove 11.

[0043] Reference Figure 2 and Figure 3 Multiple T-shaped sliding plates 22 are fixedly connected to the lower surface of the guard plate 2. The sliding plates 22 are located on the side of the drainage section 21 away from the side wall of the pit. The multiple sliding plates 22 are distributed along the length direction of the guard plate 2. In this embodiment, there are two sliding plates 22. A sliding groove 12 corresponding to the sliding plate 22 is opened on the upper surface of the base frame 1. The length direction of the sliding groove 12 is set along the width direction of the guard plate 2. The sliding groove 12 is connected to the mounting groove 11. Each sliding plate 22 is slidably inserted into the sliding groove 12 and the sliding plate 22 extends into the mounting groove 11. The upper surface of the sliding plate 22 contacts the upper groove wall of the mounting groove 11. The sliding plate 22 and the sliding groove 12 cooperate to make the guard plate 2 and the base frame 1 slidably connected.

[0044] Reference Figure 1 and Figure 2 The base frame 1 is equipped with an adjusting component 3 for adjusting the position of the guard plate 2. The adjusting component 3 includes several uprights 31 vertically fixedly connected to the upper surface of the base frame 1. In this embodiment, there are two uprights 31, which are evenly distributed along the length of the guard plate 2 on the base frame 1. In other embodiments, there may be only one upright. When there is only one upright, it is located in the middle of the base frame 1. A lead screw 32 passes through the top of the upright 31. The length direction of the lead screw 32 is consistent with the length direction of the slide groove 12, and the lead screw 32 is threadedly connected to the upright 31. A pad 34 is fixedly connected to the end of the upright 31 near the guard plate 2. The cross-sectional area of ​​the pad 34 is larger than that of the lead screw 32. A handwheel 33 is fixedly connected to the end of the lead screw 32 away from the guard plate 2.

[0045] The base frame 1 is provided with a fixing component 4 for fixing the base frame 1 to the bottom surface of the pit. The fixing component 4 includes several support rings 41 sleeved on the lead screw 32. In this embodiment, there are two support rings 41 on each lead screw 32. The two support rings 41 are located between the guard plate 2 and the upright 31. The two support rings 41 are located at both ends of the lead screw 32. An upper rod 42 is fixedly connected to the support ring 41. The outer side wall of the upper rod 42 is provided with threads.

[0046] A lower rod 43 corresponding to the upper rod 42 is slidably inserted into the base frame 1. The lower rod 43 passes through the base frame 1 and is coaxial with the corresponding upper rod 42. The lower end of the upper rod 42 is inserted into the upper end of the lower rod 43, and the lower rod 43 is threadedly connected to the upper rod 42. The lower end of the lower rod 43 is provided with a pointed tip. A ring plate 44 is fixedly connected to the side wall of the lower rod 43. The ring plate 44 is located above the base frame 1, and the outer diameter of the ring plate 44 is larger than the outer diameter of the lower rod 43.

[0047] In the initial state, the lower end of the lower rod 43 is located in the mounting groove 11, there is a gap between the ring plate 44 and the upper surface of the base frame 1, and there is also a gap between the pad plate 34 and the guard plate 2. When it is necessary to support the side wall of the foundation pit, the base frame 1 is placed in the predetermined position, and the operator adjusts the base frame 1 and the guard plate 2 so that the guard plate 2 protrudes from the side wall of the base frame 1 and contacts the corresponding side wall of the foundation pit. Then, each lower rod 43 is rotated with a tool so that the lower rod 43 is inserted into the bottom surface of the foundation pit until the ring plate 44 contacts the upper surface of the base frame 1. At this time, the base frame 1 is fixed.

[0048] After the base frame 1 is fixed, the operator turns the handwheel 33 to move the lead screw 32 and the pad 34 toward the guard plate 2 until the pad 34 contacts the guard plate 2. At this time, the pad 34, lead screw 32 and upright 31 cooperate to limit the guard plate 2, so that the guard plate 2 can support the side wall of the pit. The ring plate 44, lower rod 43, upper rod 42 and support ring 41 can also support the lead screw 32 and reduce the bending of the lead screw 32.

[0049] Reference Figure 1 and Figure 4 The base frame 1 is equipped with a drive assembly 5 that allows the protective plate 2 to further abut against the side wall of the pit. The base frame 1 is also equipped with a power assembly 6 that converts the gravity of the water into power. The power assembly 6 provides power to the drive assembly 5. The power assembly 6 includes a receiving bucket 61 set in the mounting groove 11. The top of the receiving bucket 61 and the side near the bottom wall of the mounting groove 11 are open. A sponge block 62 is placed in the receiving bucket 61. The upper surface of the sponge block 62 contacts the top wall of the mounting groove 11. The length direction of both the receiving bucket 61 and the sponge block 62 is along the length direction of the protective plate 2.

[0050] Reference Figure 2 , Figure 3 and Figure 3 The power assembly 6 also includes a water-squeezing component 63, which includes several connecting rods 631 fixedly connected to the lower surface of the slide plate 22. The connecting rods 631 penetrate the lower surface of the receiving hopper 61 and slide into the receiving hopper 61. The sponge block 62 is located between the connecting rods 631 and the side wall of the receiving hopper 61. A roller 632 is installed at the lower end of the connecting rod 631. The roller 632 rolls with the lower wall of the mounting groove 11, reducing the situation where the connecting rod 631 directly contacts the lower wall of the mounting groove 11, which would cause the connecting rod 631 to wear quickly.

[0051] Each connecting rod 631 is fitted with a support spring 633, which is located between the receiving bucket 61 and the frame of the roller 632. The support spring 633 supports the receiving bucket 61, so that there is a gap between the lower surface of the receiving bucket 61 and the lower wall of the mounting groove 11. One side of the receiving bucket 61 and the sponge block 62 protrudes from the base frame 1, and the lower surface of the drainage part 21 of the sponge block 62 contacts the upper surface of the sponge block 62. The side walls of the receiving bucket 61 and the guard plate 2 near the opening of the mounting groove 11 are flush.

[0052] Reference Figure 3The dewatering component 63 also includes a dewatering plate 634 located between the connecting rod 631 and the sponge block 62. The dewatering plate 634 is perpendicular to the inner bottom wall of the receiving hopper 61, and its length direction is along the length direction of the receiving hopper 61. Multiple guide blocks are fixedly connected to the lower surface of the dewatering plate 634. A guide groove corresponding to the guide block is opened on the inner bottom wall of the receiving hopper 61. The length direction of the guide groove is along the length direction of the sliding groove 12. Each guide block is slidably inserted into the corresponding guide groove. The guide groove and the guide block cooperate to make the dewatering plate 634 slide and cooperate with the receiving hopper 61.

[0053] A push rod 635 is hinged to the connecting rod 631. The end of the push rod 635 away from the connecting rod 631 is hinged to the side wall of the squeezing plate 634 away from the sponge block 62. In the initial state, the upper surface of the sponge block 62 is in contact with the top wall of the mounting groove 11. The push rod 635 is inclined. The end of the push rod 635 near the connecting rod 631 is lower than the end of the push rod 635 near the squeezing plate 634, and there is a gap between the end of the push rod 635 near the squeezing plate 634 and the connecting rod 631.

[0054] Reference Figure 2 and Figure 4 The power assembly 6 also includes a water collection hopper 64 located below the receiving hopper 61. The length direction of the water collection hopper 64 is the same as that of the receiving hopper 61. Rectangular guide blocks 641 are fixedly connected to the two short side walls of the water collection hopper 64. Guide rails 65 corresponding to the guide blocks 641 are fixedly connected to the two opposite walls of the mounting groove 11. The length direction of the guide rails 65 is set along the depth direction of the mounting groove 11, and the guide rails 65 are inclined. The end of the guide rails 65 near the opening of the mounting groove 11 is higher than the end of the guide rails 65 near the bottom of the mounting groove 11. Each guide block 641 is slidably inserted into the corresponding guide rail 65.

[0055] A return spring 66 is fixedly connected to the inner end face of the guide rail 65 near the bottom of the mounting groove 11. The end of the return spring 66 near the guide block 641 is fixedly connected to the guide block 641. In the initial state, the return spring 66 limits the water collection hopper 64, so that part of the water collection hopper 64 is located directly below the receiving hopper 61, and the part of the water collection hopper 64 away from the receiving hopper 61 is located on the side of the receiving hopper 61 near the bottom of the mounting groove 11.

[0056] Reference Figure 1 , Figure 2 and Figure 4The drive assembly 5 includes a vertical rod 51 passing through each slide groove 12. The lower end of the vertical rod 51 is located in the mounting groove 11 and is fixedly connected to the upper surface of the water collection hopper 64. A horizontal rod 52 is provided between two vertical rods 51. The horizontal rod 52 is located above the base frame 1, and both ends of the horizontal rod 52 are fixedly connected to the corresponding vertical rod 51. A drive rod 54 is also rotatably connected to the upper surface of the base frame 1. The drive rod 54 is located between the guard plate 2 and the horizontal rod 52. The rotation axis of the drive rod 54 is located in the middle of the drive rod 54, and the rotation axis of the drive rod 54 is set along the height direction of the base frame 1.

[0057] Reference Figure 4 A strip-shaped mating ring 53 is hinged to one end of the drive rod 54 near the crossbar 52. The length direction of the mating ring 53 is set along the height direction of the base frame 1, and the mating ring 53 is sleeved on the crossbar 52. A protrusion 55 is hinged to one end of the drive rod 54 away from the mating ring 53. A limiting groove 24 corresponding to the protrusion 55 is opened on the side wall of the guard plate 2 near the crossbar 52. The length direction of the limiting groove 24 is set along the length direction of the guard plate 2, and the protrusion 55 is slidably inserted into the limiting groove 24.

[0058] A limiting spring 56 is fixedly connected to one end of the groove wall of the limiting groove 24. The end of the limiting spring 56 near the protrusion 55 is fixedly connected to the protrusion 55. In the initial state, the limiting spring 56 is in a compressed state. The limiting spring 56 causes the protrusion 55 to abut against the groove wall of the limiting groove 24 at the end away from the limiting spring 56. There is an angle between the drive rod 54 and the guard plate 2.

[0059] When it rains or groundwater rises, water seeps from the sidewall of the foundation pit into the space between the protective plate 2 and the sidewall of the foundation pit. The water falls along the protective plate 2 onto the sponge block 62, which stores the falling water. (Refer to...) Figure 3 In order to allow water to flow better onto the sponge block 62, multiple guide grooves 23 are provided on the side wall of the guard plate 2 away from the drive block. The multiple guide grooves 23 are arranged along the length direction of the guard plate 2, and the length direction of the guide grooves 23 is set along the height direction of the guard plate 2. Both the upper and lower ends of the guide grooves 23 penetrate the guard plate 2.

[0060] As the water in the sponge block 62 gradually increases, the sponge block 62 moves downward by pressing the receiving hopper 61 and the squeezing plate 634. The receiving hopper 61 moves and compresses the support spring 633. As the squeezing plate 634 moves downward, it drives the corresponding end of the push rod 635 to rotate downward. The push rod 635 rotates and pushes the squeezing plate 634 to move closer to the corresponding side wall of the receiving hopper 61. The squeezing plate 634 cooperates with the corresponding side wall of the receiving hopper 61, thereby squeezing the sponge block 62, causing the water in the sponge block 62 to flow into the receiving hopper 61. Then, the water in the receiving hopper 61 flows downward to the water collection hopper 64 for collection.

[0061] As the water in the sponge block 62 gradually decreases, the support spring 633 returns to its original shape and pushes the receiving hopper 61 and the squeezing plate 634 upward. At the same time, the push rod 635 rotates and pulls the squeezing plate 634 towards the connecting rod 631. When the receiving hopper 61 stops moving upward, the push rod 635 stops rotating, the squeezing plate 634 stops moving, the sponge block 62 returns to its original shape, and continues to collect the falling water.

[0062] As the water in the water collection hopper 64 gradually increases, the water collection hopper 64 drives the guide block 641 to slide towards the lower end of the guide rail 65. While the guide block 641 slides, it compresses the reset spring 66. The movement of the water collection hopper 64 drives the vertical rod 51, the horizontal rod 52, and the mating ring 53 to move away from the protective plate 2. The mating ring 53 drives the drive rod 54 to rotate, causing the drive rod 54 to push the protrusion 55 to move. While the protrusion 55 moves, it further compresses the limiting spring 56. At the same time, the drive rod 54 pushes the protective plate 2 to move closer to the side wall of the pit, so that the protective plate 2 further abuts against the corresponding side wall of the pit, enabling the support structure to better support the pit and improving the support effect of the support structure on the side wall of the pit.

[0063] When the support structure needs to be removed, rotate the lower rod 43 to move it upward. When the lower end of the lower rod 43 moves into the mounting groove 11, rotate the handwheel 33 to create a gap between the pad 34 and the guard plate 2, allowing the support structure to be moved. Then tilt the base frame 1 to allow the water in the water collection hopper 64 to flow out. As the water in the water collection hopper 64 gradually decreases, the return spring 66 returns to its original shape and pushes the water collection hopper 64 to its initial position. As the water collection hopper 64 moves, it drives the vertical rod 51, the horizontal rod 52, and the mating ring 53 to move. As the mating ring 53 moves, it drives the drive rod 54 to rotate. The limit spring 56 returns to its original shape and pushes the protrusion 55 to move. When the water collection hopper 64 returns to its initial position, the drive rod 54 and the protrusion 55 also return to their initial positions.

[0064] The implementation principle of a building support structure according to an embodiment of this application is as follows: When it is necessary to support the foundation pit, the base frame 1 is placed in a suitable position, the protective plate 2 is moved to contact the side wall of the foundation pit, and then the lower rod 43 is rotated to insert the lower rod 43 into the ground. The handwheel 33 is rotated to make the pad 34 contact the protective plate 2. When water seeps out of the side wall, the water flows into the sponge block 62 along the guide channel 23. The sponge block 62 drives the receiving bucket 61 to move downward. At the same time, the push rod 635 drives the water squeezing plate 634 to move to squeeze out the water in the sponge block 62. The squeezed water flows into the water collection bucket 64. The support spring 633 restores its deformation and pushes the receiving bucket 61 and the sponge block 62 to move upward.

[0065] As the water in the collection hopper 64 gradually increases, the collection hopper 64 moves and compresses the return spring 66. The collection hopper 64 also drives the drive rod 54 to rotate, and the drive rod 54 rotates and pushes the guard plate 2 to abut against the corresponding side wall of the pit. When it is necessary to remove the support structure, the lower rod 43 and the handwheel 33 are rotated respectively, so that the lower rod 43 is located in the mounting groove 11, the pad 34 is disengaged from the guard plate 2, and finally the base frame 1 is rotated, the water in the collection hopper 64 flows out, the return spring 66 and the limit spring 56 return to their original deformation, so that the water tank and the drive rod 54 are reset.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
