Description

Technical Field

[0001] The utility model belongs to the technical field of building hoisting, and in particular relates to a hoisting and positioning structure for assembled building composite panels. Background Art

[0002] Composite slabs are prefabricated, monolithic floor slabs composed of precast panels and cast-in-place reinforced concrete layers. The precast panels serve as both a structural component and a permanent formwork for the cast-in-place reinforced concrete layers. Composite slabs offer excellent integrity and high rigidity, and their smooth upper and lower surfaces facilitate finishing. Consequently, composite slabs are increasingly used in prefabricated buildings.

[0003] Currently, at construction sites, composite slabs are hoisted onto beams using tower cranes. During the hoisting process, the slabs are suspended 30-50cm above the positioning line. Construction workers control the movement of the slabs to align them with the positioning line below. This process is visually controlled, making installation errors prone to occur. Once errors occur, construction workers must perform secondary adjustments using tools such as pry bars, which is time-consuming and labor-intensive, and may also damage the slabs. Utility Model Content

[0004] The utility model is intended to provide a hoisting and positioning structure for assembled building composite panels, so as to solve the problem of installation errors caused by visual installation of composite panels by construction workers.

[0005] In order to achieve the above-mentioned purpose, the solution of the utility model is: a lifting and positioning structure for assembled building composite panels, including a U-shaped positioning cover plate inverted on a beam body, an L-shaped fixing plate is provided on the U-shaped positioning cover plate, the L-shaped fixing plate includes a longitudinal plate and a transverse plate, a threaded adjustment rod I is threadedly connected to the longitudinal plate, the end of the threaded adjustment rod I is rotatably connected to the positioning plate I, a threaded adjustment rod II is threadedly connected to the transverse plate, the end of the threaded adjustment rod II is rotatably connected to the positioning plate II, and the positioning plate I and the positioning plate II are perpendicular to each other.

[0006] The working principle and beneficial effects of this solution are as follows: In this solution, the U-shaped positioning cover plate is inverted on the beam body, and the position of positioning plate I is adjusted by threaded adjustment rod I, and the position of positioning plate II is adjusted by threaded adjustment rod II, so that the right angle formed by positioning plates I and II coincides with the right angle when the composite panel is seated in the predetermined installation position. In this way, when the composite panel falls, the construction personnel move the composite panel so that one of the right angles of the composite panel aligns with positioning plates I and positioning plates II, and the composite panel falls against positioning plates I and positioning plates II, thus ensuring that the composite panel is accurately seated in the predetermined installation position, reducing the workload of the construction personnel and improving the efficiency of the composite panel lifting.

[0007] Optionally, the side of the positioning plate I facing the longitudinal plate is fixedly connected with a telescopic support member I, and the side of the positioning plate II facing the transverse plate is fixedly connected with a telescopic support member II.

[0008] In this solution, telescopic support member I supports positioning plate I, and telescopic support member II supports positioning plate II, making positioning plates I and II more stable when subjected to force. Furthermore, the support lengths of telescopic support member I and telescopic support member II are adjustable to accommodate the different positions of positioning plates I and II.

[0009] Optionally, a blind hole I is provided on the longitudinal plate for the telescopic support member I to sink into, and a blind hole II is provided on the transverse plate for the telescopic support member II to sink into.

[0010] In this solution, blind hole I is for telescopic support member I to sink into, and blind hole II is for telescopic support member II to sink into. Firstly, the length adjustment range of telescopic support member I and telescopic support member II is increased, and secondly, the telescopic support member can be restricted from moving radially along the blind hole, thereby preventing the positioning plate I and positioning plate II from rotating.

[0011] Optionally, the telescopic support member I and the telescopic support member II both include an outer sleeve and an internal threaded rod, and the internal threaded rod is threadedly connected to the outer sleeve.

[0012] In this solution, the support length can be adjusted by relatively rotating the internal threaded rod and the outer sleeve, which is simple to operate.

[0013] Optionally, the longitudinal plate is provided with a thickened portion I, and the blind hole I extends to the thickened portion I; the transverse plate is provided with a thickened portion II, and the blind hole II extends to the thickened portion II.

[0014] In this solution, the thickened portion I deepens the blind hole I, and the thickened portion II deepens the blind hole II, while avoiding the overall thickening of the L-shaped fixing plate.

[0015] Optionally, a horizontally arranged threaded adjustment rod III is threadedly connected to the side wall of the U-shaped positioning cover, and one end of the threaded adjustment rod III located inside the U-shaped positioning cover is connected to a tightening plate.

[0016] In this solution, the distance between the abutting plate and the other side wall of the U-shaped positioning cover can be adjusted by rotating the threaded adjustment rod III, so that it is applicable to beams of different thicknesses and has a wide range of applications.

[0017] Optionally, a side wall of the U-shaped positioning cover is provided with a thickened portion III, and the threaded adjustment rod III is threadedly connected to the thickened portion III.

[0018] In this solution, the design of the thickened portion III makes the support of the threaded adjustment rod III to the clamping plate more stable, and avoids the overall thickening of the side wall of the U-shaped positioning cover.

[0019] Optionally, the threaded adjustment rod III is rotatably connected to the abutting plate.

[0020] In this solution, after the threaded adjustment rod III is rotated to make the clamping plate contact the beam body, the threaded adjustment rod III is continued to be rotated to make the clamping plate clamped against the beam body. No sliding friction occurs between the clamping plate and the beam body, which makes it easier to fix the U-shaped positioning cover plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is further described in detail through specific implementation methods:

[0026] The marks in the drawings of the specification include: U-shaped positioning cover plate 1, thickening part III 110, threaded adjustment rod III 2, tightening plate 3, L-shaped fixing plate 4, longitudinal plate 401, thickening part I 4011, transverse plate 402, thickening part II 4021, threaded adjustment rod I 5, positioning plate I 6, threaded adjustment rod II 7, positioning plate II 8, telescopic support member I 9, telescopic support member II 10, outer tube sleeve 11, internal threaded rod 12, beam body 13, and composite plate 14.

[0027] Example 1

[0028] This embodiment is basically as Figure 1 and Figure 2 As shown: A lifting and positioning structure for assembled building composite panels, including a U-shaped positioning cover plate 1 inverted on a beam body 13, the left side wall of the U-shaped positioning cover plate 1 is integrally formed with a thickened portion III110, the thickened portion III110 is threadedly connected to a horizontally arranged threaded adjustment rod III2, the right end of the threaded adjustment rod III2 (the end located inside the U-shaped positioning cover plate 1) is rotatably connected to a clamping plate 3 through a bearing, and the clamping plate 3 is vertically arranged.

[0029] An L-shaped fixing plate 4 is welded to the outer wall of the top side of the U-shaped positioning cover 1. The L-shaped fixing plate 4 includes a longitudinal plate 401 and a transverse plate 402. A horizontally arranged threaded adjustment rod Ⅰ5 is threadedly connected to the longitudinal plate 401. The right end of the threaded adjustment rod Ⅰ5 is rotatably connected to the positioning plate Ⅰ6 through a bearing. A horizontally arranged threaded adjustment rod Ⅱ7 is threadedly connected to the transverse plate 402. The front end of the threaded adjustment rod Ⅱ7 is rotatably connected to the positioning plate Ⅱ8 through a bearing. The positioning plate Ⅰ6 and the positioning plate Ⅱ8 are perpendicular to each other. In this way, the two sides of the right angle of the composite plate 14 can contact the positioning plate Ⅰ6 and the positioning plate Ⅱ8 respectively. Figure 3 shown.

[0030] The side of the positioning plate I6 facing the longitudinal plate 401 is fixedly connected to the telescopic support member I9, and the side of the positioning plate II8 facing the transverse plate 402 is fixedly connected to the telescopic support member II10. The telescopic support member I9 and the telescopic support member II10 both include an outer cylindrical sleeve 11 and an internally threaded rod 12. The internally threaded rod 12 is threadedly connected to the outer cylindrical sleeve 11, and the end of the internally threaded rod 12 of the telescopic support member I9 away from the outer cylindrical sleeve 11 is welded to the positioning plate I6, and the end of the internally threaded rod 12 of the telescopic support member II10 away from the outer cylindrical sleeve 11 is welded to the positioning plate II8.

[0031] During actual use, the construction workers will buckle the U-shaped positioning cover plate 1 upside down on the beam body 13. At this time, the top end of the beam body 13 is embedded between the clamping plate 3 and the right side wall of the U-shaped positioning cover plate 1. Then, the threaded adjustment rod III2 is rotated, and the threaded adjustment rod III2 drives the clamping plate 3 to move to the right until the clamping plate 3 is tightly pressed against the left side wall of the beam body 13, thereby fixing the U-shaped positioning cover plate 1 on the beam body 13. It should be noted in this process that the installation position of the U-shaped positioning cover plate 1 on the beam body 13 is not on the installation position of the composite plate 14, but next to the installation position of the composite plate 14. In this way, the composite plate 14 will not press on the U-shaped positioning cover plate 1 after being installed on the beam body 13, making it convenient for the construction workers to remove the U-shaped positioning cover plate 1 after the installation of the composite plate 14 is completed.

[0032] After the U-shaped positioning cover plate 1 is fixed, the construction personnel rotate the threaded adjustment rod I5, causing the threaded adjustment rod I5 to drive the positioning plate I6 to move horizontally, and the horizontal distance between the right side wall of the positioning plate I6 and the right side wall of the beam body 13 is 10 mm (when the composite board 14 is hoisted on the beam body 13, the distance between the composite board 14 and the beam body 13 is generally 10 mm). The threaded adjustment rod II7 is then rotated, causing the threaded adjustment rod II7 to drive the positioning plate II8 to move horizontally and longitudinally, and the front side wall of the positioning plate II8 coincides with the long side of the predetermined installation position of the composite board 14. In this way, the right angle formed between the positioning plates I6 and II8 is the right angle of the predetermined installation position of the composite board 14. During this process, the construction workers rotate the outer cylinder sleeve 11 of the telescopic support member I9 according to the position of the positioning plate I6, so that the left end of the outer cylinder sleeve 11 is against the right side wall of the longitudinal plate 401, thereby supporting the positioning plate I6; and rotate the outer cylinder sleeve 11 of the telescopic support member II10 according to the position of the positioning plate II8, so that the rear end of the outer cylinder sleeve 11 is against the front side wall of the transverse plate 402, thereby supporting the positioning plate II8.

[0033] When the composite plate 14 is hoisted to the top of the predetermined installation position, the construction personnel push the composite plate 14 to move so that the right angle side of the composite plate 14 close to the positioning plate I6 is in contact with the right side wall of the positioning plate I6, and the right angle side of the composite plate 14 close to the positioning plate II8 is in contact with the front side wall of the positioning plate II8 (such as Figure 3 As shown), the composite plate 14 then falls along the positioning plate I6 and the positioning plate II8 until the composite plate 14 falls on the beam body 13, thereby achieving accurate installation of the composite plate 14 and avoiding the construction workers from adjusting the position of the composite plate 14 a second time after the composite plate 14 is seated, thereby avoiding damage to the composite plate 14 due to the secondary adjustment, reducing the workload of the construction workers, and improving the efficiency of hoisting the composite plate 14.

[0034] After the installation of the composite plate 14 is completed, the construction workers rotate the threaded adjustment rod III2 in the opposite direction, the pressing plate 3 is separated from the beam body 13, and the U-shaped positioning cover plate 1 is removed from the beam body 13. Then, according to the predetermined installation position of the next composite plate 14, the U-shaped positioning cover plate 1 is fixed to the appropriate position on the beam body 13 so as to carry out the hoisting work of the next composite plate 14.

[0035] In addition, in this embodiment, the threaded adjustment rod I5 and the threaded adjustment rod II7 can be detached from the L-shaped fixed plate 4. In this way, when the U-shaped positioning cover plate 1 is affected by the embedded steel bars on the beam body 13 and its installation position on the beam body 13 is far away from the predetermined installation position of the composite plate 14, a longer positioning plate I6 and a longer threaded adjustment rod II7 can be replaced.

[0036] Example 2

[0037] The difference between this embodiment and the first embodiment is that: Figure 4As shown, in this embodiment, the longitudinal plate 401 is provided with a blind hole I into which the telescopic support member I9 is ​​inserted, and the transverse plate 402 is provided with a blind hole II into which the telescopic support member II10 is inserted. A thickened portion I 4011 is integrally formed on the longitudinal plate 401, and the blind hole I extends to the thickened portion I 4011. The transverse plate 402 is integrally formed with a thickened portion II 4021, and the blind hole II extends to the thickened portion II 4021. Furthermore, the bottom end of the thickened portion I 4011 extends to the top surface of the U-shaped positioning cover plate 1, thereby enhancing the stability of the L-shaped fixing plate 4.

[0038] In this embodiment, the left end of the outer sleeve 11 of telescopic support member I9 is ​​sunk into blind hole I, effectively preventing telescopic support member I9 from moving radially along blind hole I, thereby restraining positioning plate I6 and preventing it from rotating. Similarly, the rear end of telescopic support member II10 is sunk into blind hole II, effectively preventing telescopic support member II10 from moving radially along blind hole II, thereby restraining positioning plate II8 and preventing it from rotating. This allows telescopic support member I9 to more stably support positioning plate I6, and telescopic support member II10 to more stably support positioning plate II8.
