Description

Technical Field

[0001] This utility model relates to the field of prefabricated construction technology, specifically a reusable temporary fixing device for the top of an infill wall. Background Technology

[0002] During the construction of cast-in-place concrete structures or prefabricated concrete structures, after the main structure is completed and reaches a certain strength, it is usually necessary to build or install infill walls within the floors to separate the building space.

[0003] Existing temporary fixing devices for infill walls only have welded parts that are compatible with a single wall thickness, making it impossible to achieve stepless and continuous clamping for infill walls of different thicknesses. Furthermore, when there are construction errors in the floor height, secondary cutting or welding is required on-site, resulting in low adjustment efficiency and poor adaptability. Based on this, this utility model designs a reusable temporary fixing device for infill walls to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a reusable temporary fixing device for the top of an infill wall, which solves the problem of low adaptability in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A reusable temporary fixing device for infill wall tops, comprising: A fixed frame is provided, with a fixing screw installed on the top of the fixed frame. The outer ring of the fixing screw is threadedly connected to a lifting block, and a top plate is provided on the top of the lifting block. An adjustment mechanism is located inside a fixed frame and clamps walls of different widths. The adjustment mechanism includes a rotating component and a fixing component. The rotating component is located inside the fixed frame and drives the fixing component to move. The fixing component is located on one side of the rotating component and clamps and fixes walls of different widths. A disassembly mechanism is located at the top of the fixed frame and facilitates the disassembly and installation of the top plate.

[0006] Preferably, the rotating assembly includes a rotating screw hole formed inside the fixed frame, a rotating screw is threadedly connected to the inside of the rotating screw hole, a rotating component is installed on one side of the rotating screw, and two sets of the rotating screw and the rotating component are provided and symmetrically distributed.

[0010] Preferably, the limiting component includes a connecting plate installed on one side of the lifting block, and both the connecting plate and the fixed frame have limiting screw holes inside, with a limiting screw rod threaded into the internal of the limiting screw hole.

[0011] Preferably, the mounting screw holes are provided in multiple sets and arranged in a circumferential array, and the mounting screws are provided in multiple sets and arranged in a circumferential array.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. This utility model utilizes the synergistic effect of a bidirectional rotating screw and a rectangular array of limiting telescopic rods to allow two fixing plates to continuously move closer or further apart within a certain range, achieving rapid and stable clamping of infill walls of different thicknesses.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 A reusable temporary fixing device for infill wall tops includes: a fixing frame 1, a fixing screw 2 installed on the top of the fixing frame 1, a lifting block 3 connected to the outer ring of the fixing screw 2, and a top plate 4 provided on the top of the lifting block 3; An adjustment mechanism is located inside the fixed frame 1 and clamps walls of different widths. The adjustment mechanism includes a rotating component and a fixed component. The rotating component is located inside the fixed frame 1 and drives the fixed component to move. The fixed component is located on one side of the rotating component and clamps and fixes walls of different widths. The disassembly mechanism is located on top of the fixed frame 1 and facilitates the disassembly and installation of the top plate 4.

[0018] The rotating assembly includes a rotating screw hole 5 inside the fixed frame 1, with a rotating screw 6 threadedly connected inside the rotating screw hole 5. A rotating component 7 is mounted on one side of the rotating screw 6. Two sets of rotating screws 6 and rotating components 7 are provided and symmetrically distributed. The fixing assembly includes a fixing plate 8 mounted on the other side of the rotating screw 6. Two sets of fixing plates 8 are provided and symmetrically distributed. A telescopic assembly is installed between the fixed frame 1 and the fixing plate 8. The telescopic assembly includes limiting telescopic rods 9 installed between the fixed frame 1 and the fixing plate 8. Multiple sets of limiting telescopic rods 9 are provided and distributed in a rectangular array.

[0019] In this embodiment of the invention, by rotating two sets of symmetrically arranged rotating screws 6, axial displacement is generated within the rotating screw holes 5. The rotating screws 6 drive the fixed plates 8, which are fixed to them, to move synchronously closer to or further away from the sides of the wall. With the guiding effect of multiple limiting telescopic rods 9 in the telescopic assembly, the two fixed plates 8 can adaptively clamp walls of different thicknesses. The limiting telescopic rods 9 are distributed in a rectangular array, which can effectively suppress the deflection of the fixed plates 8 during the clamping process, ensure uniform force distribution, and avoid local pressure damage to the wall.

[0020] Please refer to Figures 1-4The disassembly mechanism includes a fixing ring 10 installed on the top of the lifting block 3. Both the fixing ring 10 and the top plate 4 have mounting screw holes 11 inside. A mounting screw 12 is threaded into the mounting screw holes 11. A limit assembly is installed between the lifting block 3 and the fixed frame 1. The limit assembly includes a connecting plate 13 installed on one side of the lifting block 3. Both the connecting plate 13 and the fixed frame 1 have limit screw holes 14 inside. A limit screw 15 is threaded into the limit screw holes 14.

[0021] The mounting screw holes 11 are provided in multiple sets and arranged in a circular array, and the mounting screws 12 are provided in multiple sets and arranged in a circular array.

[0022] In this embodiment of the utility model, once the caulking material at the top of the infill wall has cured to the design strength, the top plate 4 and the lifting block 3 can be quickly separated simply by unscrewing the mounting screw 12; then, the rotating screw 6 is rotated in the opposite direction, the fixing plate 8 loosens the wall, and the entire device can be dismantled without damage and reused on the next working surface; the multiple sets of mounting screw holes 11 and mounting screws 12 arranged in a circumferential array not only improve the connection strength of the top plate 4, but also facilitate the flexible adjustment of the orientation of the top plate 4 according to the site conditions, so as to achieve rapid assembly and disassembly.

[0023] In use, the overall frame is first placed on top of the infill wall to be fixed. By rotating the two sets of symmetrically arranged rotating screws 6, axial displacement is generated within the rotating screw holes 5. The rotating screws 6 drive the fixed plates 8, which are fixed to them, to move synchronously closer to or further away from both sides of the wall. With the guiding action of the multiple limiting telescopic rods 9 in the telescopic assembly, the two fixed plates 8 can adaptively clamp walls of different thicknesses. The limiting telescopic rods 9 are distributed in a rectangular array, which can effectively suppress the deflection of the fixed plates 8 during the clamping process, ensure uniform force distribution, and avoid local pressure damage to the wall.

[0024] Once the wall is clamped, the rotating lifting block 3 forms a threaded transmission with the fixing screw 2. Under the coordinated action of the threaded helix angle and the limiting components, the lifting block 3 drives the top plate 4 to rise and fall smoothly in the vertical direction until the upper surface of the top plate 4 is tightly fitted against the bottom of the beam, forming a reliable temporary vertical support. At this point, the reserved gap between the top of the infill wall and the bottom of the beam is temporarily sealed by the top plate 4, and the wall obtains stable out-of-plane constraints, enabling it to resist horizontal vibrations and accidental collisions during the construction phase.

[0025] The limiting assembly consists of a connecting plate 13, a limiting screw hole 14, and a limiting screw 15. When the top plate 4 reaches the required height, the limiting screw 15 is screwed into the limiting screw hole 14 corresponding to the connecting plate 13 and the fixed frame 1 to lock the vertical position of the lifting block 3, preventing the top plate 4 from sliding down due to vibration or accidental contact, and further improving the reliability of the temporary support.

[0026] The disassembly mechanism adopts a modular design. The top plate 4 is detachably connected to the fixing ring 10 through the mounting screw holes 11 and mounting screws 12. After the caulking material at the top of the infill wall has cured to the design strength, the top plate 4 and the lifting block 3 can be quickly separated simply by unscrewing the mounting screws 12. Then, the screws 6 are rotated in the opposite direction, the fixing plate 8 is loosened from the wall, and the entire device can be disassembled without damage and reused on the next working surface. The multiple sets of mounting screw holes 11 and mounting screws 12 arranged in a circumferential array not only improve the connection strength of the top plate 4, but also facilitate the flexible adjustment of the orientation of the top plate 4 according to the site conditions, so as to achieve rapid assembly and disassembly.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
