Description

Technical Field

[0001] This utility model relates to the technical field of lightweight partition wall connection devices, and in particular to an adjustable lightweight concrete partition wall connection device. Background Technology

[0002] In prefabricated buildings, U-shaped steel clips are commonly used as connectors between lightweight concrete partition walls and the main structure. During construction, workers drill holes in the floor, ceiling, and side walls according to the layout dimensions, then fix the steel clips with expansion bolts. The partition wall panels are then inserted into the slots of the steel clips and secured with wedging, grouting, or sealant to complete the positioning. This method is simple in construction and inexpensive, and has been included in prefabricated interior partition wall construction atlases in most regions, with an application rate exceeding 80%.

[0003] Once the steel clips are anchored, their horizontal position cannot be adjusted. However, the finished surface of the structure on site often has a construction error within ±10 mm, which often causes the partition wall panel to misalign with the groove of the steel clip after it is in place. This requires secondary chiseling, padding, or welding, which is labor-intensive and damages the finished product. This cannot meet the current green construction requirements of "reversible installation and reusability". In view of this, an adjustable concrete lightweight partition wall connection device is proposed to solve the above problems. Utility Model Content

[0004] In view of this, embodiments of the present invention provide an adjustable lightweight concrete partition wall connection device to solve the technical problem that existing lightweight concrete partition wall connectors cannot be adjusted according to actual construction errors after installation.

[0005] An embodiment of this utility model provides an adjustable lightweight concrete partition wall connection device, comprising: Two fixing brackets are provided, both of which are installed on the inner wall surface of the wall, and a gap is reserved between the two fixing brackets. A sliding mechanism is slidably connected to both of the aforementioned fixed frames. The sliding mechanism includes a sliding plate, a top plate, and multiple gears. The middle of the sliding plate extends upward in an inverted T-shape, and the extended end is connected to the top plate so that the sliding plate can pass through the gap between the two fixed frames and slide along the gap direction. Each gear is rotatably mounted on the sliding plate, and each gear meshes with the fixed frame to reduce the movement offset between the sliding plate and the two fixed frames. Two locking components are slidably disposed below the sliding mechanism. By moving the two locking components closer to each other, the lightweight partition wall can be clamped and positioned. And a locking element, which can be engaged with the fixed frame to lock the relative position of the sliding mechanism and the fixed frame. The locking element includes a mounting base, at least two snap ring blocks, an elastic element, and at least two pull ropes. The two snap ring blocks are symmetrically arranged on the mounting base. The elastic element is arranged between the two snap ring blocks to push the two snap ring blocks away in opposite directions. The two pull ropes are respectively connected to the two snap ring blocks for pulling the two snap ring blocks closer together. The two snap ring blocks are engaged with the fixed frame accordingly.

[0006] Furthermore, each of the fixing frames includes an L-shaped guide rail and a rack disposed on the guide rail close to the inner wall surface of the wall. The guide rail has a locking hole on the side away from the tooth surface of the rack. The two locking spring blocks open under the elastic force of the elastic element and can engage with the locking hole.

[0007] Furthermore, the upper part of the slide plate is provided with two guide blocks, and the distance between the two guide blocks is configured to be the same as the gap between the two fixing frames. By sliding the L-shaped part formed between the guide blocks and the slide plate with the guide rail, the sliding level of the slide plate can be improved.

[0008] Furthermore, each of the clamps includes a steel clamp and two side plates. The ends of the two side plates are perpendicularly connected to the steel clamp, and the two side plates extend upward. The two side plates are slidably connected to the slide plate, so that the steel clamp is guided relative to the sliding trajectory of the slide plate.

[0009] Furthermore, each of the aforementioned clips also includes an adjusting screw, and a connecting portion extends downward from the lower part of the slide plate. The adjusting screw is connected between the connecting portion and a steel clamp. By rotating the adjusting screw, the distance between the steel clamp and the slide plate can be adjusted.

[0010] Furthermore, four gears are rotatably mounted on the slide plate. The four gears are arranged in a rectangular shape on the slide plate, and two gears on the same side simultaneously mesh with a rack.

[0011] Furthermore, the mounting base has a through hole in the middle, and a positioning block is connected to the bottom of the mounting base by two pull ropes. The width of the positioning block is greater than the diameter of the through hole.

[0012] Furthermore, a pull ring is provided on the outside of the positioning block.

[0013] Furthermore, the elastic element is a spring rod, and its two ends are respectively hinged to the two snap ring blocks.

[0014] Furthermore, the upper end of each of the aforementioned snap ring blocks is trapezoidal.

[0015] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The adjustable lightweight concrete partition wall connection device of this utility model provides a stepless rolling reference for the sliding mechanism through the fixed frame. The inverted T-shaped neck of the sliding plate and the top plate clamping fixed frame form a fall-proof track pair. The four-point meshing of the gear and rack converts the thrust into low-damping rolling while suppressing the torsion of the sliding plate with normal limit, so that the partition wall is pushed without swaying or scraping throughout the process. The clamping part achieves self-locking clamping by a two-stage composite connection of the sliding rail fast approach and the adjusting screw micro-clamping, which not only ensures universal clamping for partition walls of different thicknesses but also prevents vibration and loosening. The locking part uses the trapezoidal guide surface and spring rod elastic snap-fit ​​to achieve one-way insertion and two-way locking. The pull rope centralized unlocking can be completed by one hand for high-altitude rapid assembly and disassembly, which significantly reduces the construction intensity and improves the assembly efficiency. At the same time, all parts can be disassembled and reused without damage, meeting the requirements of green construction. Attached Figure Description

The content protected by this utility model does not involve any improvement to the internal structure and method.

[0023] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to Figures 1 to 4 An embodiment of this utility model provides an adjustable lightweight concrete partition wall connection device, which includes: two fixing frames 2, a sliding mechanism 3, a locking component 4, and a locking component.

[0025] Two fixing brackets 2 are symmetrically fixed to the inner wall of the poured concrete wall 1 by expansion bolts. Each fixing bracket 2 includes an L-shaped guide rail 21, whose vertical wing is attached to the wall 1 by expansion bolts and whose horizontal wing extends towards the interior space; a rack 23, which is locked to the inner side of the vertical wing (i.e. the side close to the wall 1) by countersunk screws. The rack 23 has a module m=1.25 and a tooth width of 8mm, and is used to mesh with the gear 33 described later. In this embodiment, the guide rail 21 is also provided with a locking hole 22, which is a circular through hole that passes through the horizontal wing of the L-shaped guide rail 21. The hole diameter is 8mm and it is arranged at equal intervals of 100mm along the longitudinal direction of the guide rail 21. It is used to form a detachable locking connection with the locking spring block 6 of the locking member.

[0026] It is worth noting that after the two fixed frames 2 are installed, a gap D=30mm is reserved between their horizontal wings. This gap also serves as a guide channel for the sliding mechanism 3.

[0027] More specifically, the locking element is used to lock the sliding mechanism 3 to the fixed frame 2 after it reaches the designed position, so as to prevent slippage due to stress.

[0028] In this embodiment, the locking component includes: a mounting base 5 with a through hole 9 of 10mm in diameter in the middle; two snap ring blocks 6, which are symmetrically arranged in the upper part of the mounting base 5, and the upper end is machined into a trapezoidal guide surface to facilitate automatic engagement when inserted into the snap ring hole 22; It should be noted that the locking component also includes an elastic element 7. In this embodiment, a spring rod is used, with its two ends hinged to the inner sides of the two snap ring blocks 6 respectively. The free length is 40mm, and when the compression is 5mm, it can provide a tension of about 30N to ensure that the snap ring blocks 6 always have a tendency to open outward. It also includes a pull rope 10, one end of which is pressed against the inner wall of the snap ring block 6, and the other end passes downward through the through hole 9 and is connected to the positioning block 8. The positioning block 8 is 15mm wide, which is larger than the diameter of the through hole 9, so as to prevent the pull rope 10 from completely retracting. The positioning block 8 is provided with a pull ring 11 on the outside, which makes it easy for the operator to pull with one hand. Locking action: When the sliding mechanism 3 slides to the target position, it pushes the mounting base 5 to make the snap ring block 6 move upward and pass through the snap hole 22, and under the action of the spring rod, it engages with the snap hole 22; Unlocking action: Pull down the pull ring 11, the two snap ring blocks 6 overcome the tension of the spring rod and retract inward, disengaging from the locking hole 22, and the sliding mechanism 3 can continue to slide.

[0029] Please refer to Figure 3 In this embodiment, the sliding mechanism 3 is slidably connected to both fixed frames 2. It includes: a sliding plate 31, which extends upward from the middle to form an inverted T-shaped neck with a neck width of 28mm, slightly smaller than the gap D, for passing through the gap between the two fixed frames 2; a top plate 32, which is locked to the top of the inverted T-shaped neck by M6 stainless steel countersunk screws, and the lower surface of the top plate 32 is parallel to the upper surface of the horizontal wing of the fixed frame 2; and a plurality of gears 33, four of which are arranged in a rectangular four-corner configuration in this embodiment. It should be noted that the module of gear 33 is the same as that of rack 23. Gear 33 is rotatably mounted on slide plate 31 through stainless steel pin and shaft retaining ring. The four gears 33 mesh with the corresponding rack 23 at the same time to form a rolling pair, which can convert the sliding friction between slide plate 31 and fixed frame 2 into rolling friction, significantly reducing sliding resistance and suppressing lateral displacement. It is worth noting that the sliding mechanism 3 also includes two guide blocks 34, which are integrally formed on the upper surface of the slide plate 31, one on each side. The distance between the outer surfaces of the two guide blocks 34 is equal to the gap D, and they slide in cooperation with the inner side of the vertical wing of the L-shaped guide rail 21 to further improve the levelness of the sliding.

[0030] Please refer to Figure 4In this embodiment, the clamping members 4 are arranged in pairs below the sliding plate 31, and are configured to clamp light partition walls with different thicknesses ranging from 75 mm to 150 mm. Each clamping member 4 comprises a steel clip 41 and two side plates 42, the side plates 42 are bent and extended upward from both sides of the steel clip 41, and the top ends of the side plates 42 are flanged inward to form a transverse sliding pair with the sliding plate 31, so that the sliding track of the steel clip 41 is strictly guided to prevent clamping deflection; In this embodiment, the clamping member 4 is further provided with an adjusting screw 43, one end of the adjusting screw is rotatably connected to the lower part of the sliding plate 31 through a housed bearing, and the other end is threadedly connected to the steel clip 41; the distance between the two steel clips 41 can be steplessly adjusted by rotating the adjusting screw 43, so as to complete positioning for partition walls of different thicknesses.
