Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to an underpinning wall support structure. Background Art

[0002] During building relocation, underground space expansion, or historical building renovation projects, underpinning wall structures are used to temporarily support wall loads and ensure the stability of the superstructure during construction. Existing technologies often use steel sections (such as H-beams and I-beams) running horizontally through the wall, or they are secured with a combination of vertical steel beams and tension bolts.

[0003] For example, the utility model with the publication number CN213709554U discloses an internal support steel column replacement structure including a support beam and a steel column, wherein the steel column supports the support beam, and an upper support member and a lower support member are provided on the steel column, wherein the upper support member and the lower support member are arranged in opposite directions along the radial direction of the steel column, and an overhead area that can accommodate objects of a certain volume is formed by supporting angle plates between the upper support member and the lower support member. The steel column located in the area of the overhead area serves as a replacement part, and after being cut off, a replacement area for arranging the main beam is formed. The upper support member and the lower support member are respectively composed of a vertical steel plate, a horizontal steel plate and a stiffening plate. The upper support member and the lower support member also serve as a new support and force-bearing system for the steel column, effectively solving the problem of conflict between the steel column and the main beam during foundation pit construction.

[0004] Most existing supporting components are of fixed size and difficult to adapt to structures of different thicknesses or special shapes (such as curved walls and inclined walls). When the wall span is large, multiple sections of supporting rods need to be welded or bolted on site, but the traditional connection method relies on manual positioning, the splicing efficiency is low and the accuracy is difficult to guarantee. In basements or dense buildings, large lifting equipment cannot enter, and small modular components need to be manually transported and quickly spliced. During the replacement process, support segments need to be increased or decreased in real time according to wall settlement monitoring data (such as adding intermediate support points). However, the disassembly and reassembly of the existing structure is time-consuming, and the bolt connection requires the cooperation of multiple people. The risk of high-altitude operations is high, and the welding splicing is irreversible, which can easily damage the wall during dismantling.

[0005] Therefore, a supporting structure for a wall is proposed to solve the problems raised in the background art. Summary of the Invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides a support structure for a wall support.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a supporting structure for a clamping wall, comprising a support frame, wherein the support frame is used to support the clamping wall, the top of the support frame is T-shaped and contacts the wall surface, and has strong rigidity and hardness; A splicing structure, located at the bottom of the support frame, is used to quickly assemble multiple support frames to enable use in different scenarios; Among them, the splicing structure includes an assembling block, two symmetrical fixing clamps arranged on one side of the assembling block, and a driving component located on the assembling block. The driving component is used to drive the two fixing clamps to quickly fix the assembling block to achieve a quick splicing effect.

[0008] Preferably, the assembly block is rectangular and has a mounting groove on one side, the mounting groove is a circular groove, the two fixing clamps are symmetrically distributed inside the mounting groove, and a splicing card is fixedly provided on the side of the assembly block away from the mounting groove.

[0009] Preferably, a circular groove is provided at the center of the splicing card plate, and the fixing clamp can pass through the splicing card plate and be clamped at the edge of the circular groove on the splicing card plate.

[0010] Preferably, two connecting plates are fixedly provided on both sides of the inner wall of the installation groove, and limiting columns are fixedly provided on one side of the two connecting plates close to the fixed clamping block.

[0011] Preferably, oblique grooves are formed on the surfaces of the two fixing clamping blocks, and the limiting columns are clamped inside the oblique grooves.

[0012] Preferably, the fixing clamp is L-shaped and the side away from the connecting plate is protruding and is clamped with the splicing card.

[0013] Preferably, the driving assembly includes a driving part arranged inside the assembling block, a movable column arranged for transverse sliding at the center of the assembling block, a sleeve arranged on the outside of the movable column on a side away from the driving part, and a spring fixedly arranged inside the sleeve, and protruding plates are fixedly provided on both sides of the sleeve, and the two protruding plates are respectively hinged to the side of the two fixed clamps away from the protruding ends.

[0014] Preferably, the cross-section of the movable column is T-shaped and gradually shrinks on the side close to the sleeve. The spring is sleeved on the outer wall of the smaller side of the movable column. A limit box is fixedly provided on the side of the mounting groove close to the driving part. The movable column passes through the limit box, and the side of the spring away from the sleeve is fixedly connected to the limit box.

[0015] Preferably, the driving part includes a supporting block, a connecting rod fixedly arranged on the top of the supporting block, an inclined block fixedly installed on the top of the connecting rod, and a sliding frame fixedly arranged on the top of the inclined block.

[0016] Preferably, the assembly block is provided with two longitudinal through slots on a side away from the mounting slot, the through slots on both sides being slidably engaged with the connecting rod and the sliding frame respectively, the movable column is provided with a trapezoidal slot, the inclined block is engaged inside the trapezoidal slot, and the two through slots are connected to the trapezoidal slot at the center; The driving part is used to drive the movable column to slide inside the assembly block, thereby driving the angle of the fixed clamping block to change, and the support block is in contact with the ground.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the rapid assembly of multiple support frames by arranging the coordination of structures such as assembling blocks, fixing clamping blocks and driving components. After the multiple support frames are transported to the use site, rapid assembly is achieved by using the splicing structure: the assembling blocks of adjacent support frames are docked with the splicing card plate through the installation groove, and after the fixing clamping block passes through the splicing card plate, it is driven by the driving component to deflect and lock it, thereby completing the modular splicing of the support frame to meet the support requirements of different walls, and solving the problem that the existing support components are mostly fixed in size, difficult to adapt to different walls, and inconvenient to assemble and disassemble.

[0018] The present invention facilitates the adjustment of the angles of the two fixed clamps by arranging the coordination of structures such as a driving part, a movable column, a sleeve and a spring. The driving assembly pushes the movable column outward through the driving part, driving the sleeve to compress the spring, causing the hinged fixed clamp to deflect, and its protruding end clamps the splicing plate to achieve rapid fixation, thereby completing the splicing assembly of the support frame.

[0019] The present invention facilitates the rapid adjustment of the position of the movable column by arranging the coordination of structures such as the support block, the connecting rod and the oblique block. The driving part pushes the connecting rod and the oblique block under pressure through the support block, so that the sliding frame moves upward along the through slot, and the oblique block squeezes the trapezoidal slot of the movable column to move outward, driving the fixed clamp block to lock the splicing card plate; when disassembling, the support block is lifted off the ground, the spring resets to pull the sleeve back, and the fixed clamp block is separated from the card plate, thereby realizing rapid disassembly and assembly.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, the present invention provides a support structure for a supporting wall, including a support frame 1, which is used to support the supporting wall. The top of the support frame 1 is T-shaped and contacts the wall surface, and has strong rigidity and hardness. The splicing structure 2 is located at the bottom of the support frame 1 and is used to quickly assemble multiple support frames 1 to achieve use in different scenarios; The splicing structure 2 includes an assembling block 21, two symmetrical fixing clamps 22 arranged on one side of the assembling block 21, and a driving component 23 located on the assembling block 21. The driving component 23 is used to drive the two fixing clamps 22 to quickly fix the assembling block 21 to achieve a quick splicing effect. The assembling block 21 is rectangular in shape and has a mounting groove 211 on one side. The mounting groove 211 is a circular groove. The two fixing clamps 22 are symmetrically distributed inside the mounting groove 211. A splicing card plate 212 is fixedly provided on the side of the assembling block 21 away from the mounting groove 211. A circular groove is provided at the center of the splicing card plate 212. The fixing clamp 22 can pass through the splicing card plate 212 and be clamped at the edge of the circular groove on the splicing card plate 212. Two connecting plates 213 are fixedly provided on both sides of the inner wall of the mounting groove 211. Limiting columns are fixedly provided on the side of the two connecting plates 213 close to the fixing clamp 22. The surfaces of the two fixing clamps 22 are provided with oblique grooves 221, and the limiting columns are clamped inside the oblique grooves 221. The fixing clamp 22 is L-shaped and the side away from the connecting plate 213 is in a protruding state and is clamped with the splicing card plate 212.

[0024] The above solution is adopted: by carrying multiple support frames 1 to the place where they need to be used, at this time, according to the specific wall that needs to be supported, the splicing structure 2 is used to realize the rapid assembly and splicing of multiple support frames 1. Specifically, by first bringing the two support frames 1 close to each other so that the two assembling blocks 21 at the bottom are synchronously close to each other, so that the installation grooves 211 of the two adjacent assembling blocks 21 are close to the splicing card plate 212, and the fixed clamping block 22 inside the installation groove 211 is passed through the middle of the splicing card plate 212 on the other assembling block 21. At this time, the driving component 23 is used to drive the angles of the two fixed clamping blocks 22 inside the installation groove 211 to deflect, so that the protruding ends of the two are close to the splicing card plate 212 and abut against the splicing card plate 212, so as to achieve rapid fixation of the two assembling blocks 21, and then achieve rapid assembly of the two support frames 1, thereby arranging and assembling in sequence to adapt to different usage conditions.

[0025] like Figure 6 As shown, the driving assembly 23 includes a driving portion 231 disposed inside the assembly block 21, a movable column 232 that is laterally slidably disposed at the center of the assembly block 21, a sleeve 233 that is sleeved on the outside of the movable column 232 away from the driving portion 231, and a spring 234 that is fixedly disposed inside the sleeve 233. Both sides of the sleeve 233 are fixedly provided with protruding plates, and the two protruding plates are respectively hinged to the sides of the two fixed clamping blocks 22 away from the protruding ends. The cross-section of the movable column 232 is T-shaped and gradually shrinks on the side close to the sleeve 233. The spring 234 is mounted on the outer wall of the smaller side of the movable column 232. A limit box is fixedly provided on the side of the mounting groove 211 close to the driving part 231. The movable column 232 passes through the limit box, and the spring 234 is fixedly connected to the limit box on the side away from the sleeve 233.

[0026] Using this approach, during the splicing operation, the operator first accurately positions the splicing structure 2 through the splicing clamps 212 of the adjacent support frames. The operator then activates the drive unit 231, which serves as the power source for the entire drive system and drives the movable column 232 horizontally through a precision transmission mechanism. It is noteworthy that the movement direction of the movable column 232 has been carefully designed to smoothly move away from the fixed clamp 22. This motion trajectory creates the necessary conditions for the subsequent locking action. As the movable column 232 moves outward, the sleeve 233 at its top also moves synchronously. This movement compresses the internal spring 234, which acts as a buffer and stores the necessary elastic potential energy. A specially designed hinge mechanism plays a key role here: the fixed clamp 22, hinged to the protruding plate, begins to deflect at a precise angle, driven by the sleeve 233. This deflection is amplified by a carefully calculated leverage ratio, allowing the protruding end of the fixed clamp 22 to approach the splicing plate 212 at an optimal angle. When the protruding end of the fixed clamp 22 contacts the splicing plate 212, the system enters the final locking stage. The preload of the spring 234 ensures sufficient positive pressure on the contact surface, while the unique design of the hinge point allows the fixed clamp 22 to adaptively adjust its angle, ensuring surface contact with the splicing plate 212 rather than point contact. This significantly improves the stability and load-bearing capacity of the connection. The entire locking process is smooth and reliable, without shock or vibration, effectively protecting the connected components.

[0027] like Figure 7 As shown, the driving portion 231 includes a support block 2311, a connecting rod 2312 fixedly mounted on the top of the support block 2311, an inclined block 2313 fixedly mounted on the top of the connecting rod 2312, and a sliding frame 2314 fixedly mounted on the top of the inclined block 2313; Two longitudinal through slots are formed on one side of the assembly block 21 away from the mounting slot 211. The two through slots are slidably engaged with the connecting rod 2312 and the sliding frame 2314 respectively. A trapezoidal slot is formed on the movable column 232, and the inclined block 2313 is engaged inside the trapezoidal slot. The two through slots are connected to the trapezoidal slot at the center. The driving portion 231 is used to drive the movable column 232 to slide inside the assembly block 21, thereby driving the fixed clamping block 22 to change its angle, and the support block 2311 contacts the ground.

[0028] Using this approach, during the splicing operation, the two assembly blocks 21 of the support frame 1 to be connected are first brought close together, allowing the fixed clamping block 22 to initially engage and position itself with the splicing clamping plate 212. The assembled unit is then placed vertically on the ground. The bottom support block 2311 is then subjected to the ground's reaction force, generating an upward compressive force. This force is transmitted sequentially through a precise transmission mechanism: first, the top connecting rod 2312 is pushed upward, which in turn drives the inclined block 2313 and the sliding frame 2314 to slide upward synchronously along the pre-set through-slots within the assembly block 21. The specially designed trapezoidal groove structure plays a key role in this process. The trapezoidal groove on the moving column 232 forms a precise inclined surface with the inclined block 2313. When the inclined block 2313 moves upward, the mechanical conversion of the inclined surface converts vertical motion into horizontal displacement, forcing the moving column 232 to move smoothly away from the fixed clamping block 22. This movement simultaneously triggers a chain reaction: the outward movement of the moving column 232 causes the sleeve 233 to move, causing the internal spring 234 to enter a compressed energy-storing state. At the same time, the fixed clamp 22, guided by the coordinated action of the bevel slot 221 and the limiting post, produces a precise angular deflection, with its protruding end rotating toward the splicing plate 212 and ultimately forming a secure mechanical lock. The entire transmission process achieves a mechanical transformation from vertical pressure to horizontal displacement and then to rotational locking, ensuring a secure and reliable connection. When disassembly is necessary, the operation is even simpler: simply lift the support frame 1 off the ground to release the force on the support block 2311. At this point, the compressed spring 234 releases its stored energy, pushing the sleeve 233 back to its original position, driving the movable post 232 back to its original position. During the reset process, the bevel block 2313 slides down the trapezoidal slot, and the fixed clamp 22, guided by the bevel slot 221 and the limiting post, automatically disengages from the splicing plate 212, completing the quick unlocking process. This design not only enables intelligent operation—place to lock, lift to disassemble—but also ensures that all moving parts operate within the assembly block 21, preventing external interference and extending its service life.

[0029] The working principle and usage process of the present invention: The specific usage process of the device is as follows: First, multiple support frames 1 are transported to the construction site by means of transportation, and are quickly assembled using the splicing structure 2 according to the actual wall support requirements. During assembly, the operator brings the two adjacent assembly blocks 21 closer to each other and aligns them so that the fixed clamping block 22 accurately passes through the preset hole position of the splicing card 212. The assembly unit is then placed stably on the ground. At this time, the support block 2311 is subjected to the reaction force of the ground, pushing the connecting rod 2312 and the inclined block 2313 to slide upward along the internal groove of the assembly block 21. This movement converts vertical pressure into horizontal displacement through the cooperation of the inclined block 2313 and the trapezoidal groove on the movable column 232, driving the movable column 232 to move outward. During this process, the sleeve 233 moves downward and compresses the spring 234. At the same time, the fixed clamp 22 rotates under the guidance of the inclined groove 221 and the limit column, so that its protruding end is tightly abutted against the locking surface of the splicing card 212, completing a firm mechanical interlock. This design can not only adapt to the support angle requirements of different walls, but also when disassembling, it is only necessary to lift the support frame off the ground. After the force on the support block 2311 is released, the compressed spring 234 pushes the sleeve 233 to reset, driving the fixed clamp 22 to automatically detach from the splicing card 212, realizing rapid and lossless disassembly, greatly improving construction efficiency and reducing labor intensity. The entire system realizes the modular assembly and convenient disassembly and assembly functions of the support structure through ingenious mechanical linkage design.
