Description

Technical Field

[0001] This utility model relates to a hoisting and construction device for sandwich wall panels, belonging to the technical field of sandwich wall panels. Background Technology

[0002] Sandwich insulation wall technology is a significant innovation in building energy conservation. Its core utilizes a "sandwich" composite structure: an inner load-bearing structural layer (concrete or masonry), a middle layer filled with high-efficiency insulation materials (such as EPS, XPS, or rock wool), and an outer protective layer. This technology overcomes the technical bottlenecks of traditional external insulation, which is prone to aging and detachment, balancing structural safety and insulation performance, making it particularly suitable for high-rise buildings and cold regions. Integrated construction is achieved through layered casting or prefabrication processes, resulting in superior fire resistance, high durability, and low thermal bridging effects. Compared to single-wall structures, sandwich insulation systems can improve building energy efficiency by over 40% while reducing life-cycle maintenance costs, aligning with the sustainable development concept of green buildings, and has been widely adopted in recent years. However, during sandwich wall panel construction, the large size and weight of the panels make them susceptible to damage during transportation, especially the edges and insulation layer. Furthermore, the use of bolts for installation can damage the wall surface, affecting the insulation effect. Precise alignment of the panels during installation is also challenging, necessitating the development of construction equipment to address these issues. Utility Model Content

Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] Please see Figures 1 to 5 This embodiment provides a sandwich wall panel hoisting construction device, including a clamping unit. The clamping unit includes a U-shaped plate 1 with a clamping groove 11, an airbag 2 fixedly laid in the clamping groove 11, a pressure gauge 3 installed outside the U-shaped plate 1 and connected to the airbag 2, and a lifting lug 4 installed at the outer end of the U-shaped plate 1. The horizontal interface of the airbag 2 is U-shaped so as to clamp the sandwich wall panel. The airbag 2 has an inflation port 21.

[0021] The clamping unit, composed of U-shaped plates 1, airbags 2, pressure gauges 3, and lifting lugs 4, allows multiple U-shaped plates 1 to be placed on both sides of the sandwich wall panel during hoisting. The airbags 2 are inflated to clamp the sandwich wall panel. The pressure gauge 3 controls the clamping force within a safe range. The hoisting machinery uses the lifting lugs 4 to lift and hoist the wall panel, avoiding direct force damage to the wall panel.

[0022] To protect the corners of the sandwich wall panel, this device also includes a protection unit, which includes a protection plate 5. The protection plate 5 is formed by the perpendicular connection of a first panel 51 and a second panel 52. The protection plate 5 is fixedly installed at the two inner corners within the clamping groove 11, and the airbag 2 is fixed to the inner side of the protection plate 5. The protection plate 5 can protect the corners of the sandwich wall panel, preventing damage to the corners during hoisting and positioning. Specifically, the U-shaped plate 1 is a U-shaped steel plate, and the protection plate 5 is an L-shaped steel plate. The L-shaped steel plate is connected to the U-shaped steel plate by fasteners (such as bolts).

[0023] For ease of operation, multiple clamping units are spaced apart on the protective plate 5, and airbags 2 of the clamping units are connected by airbag connecting pipes 9. That is, the bottom of the upper airbag 2 is connected to the inflation port 21 of the lower airbag 2 through the airbag connecting pipes 9. In this way, gas can be injected through the inflation port 21 of the top airbag 2 to achieve simultaneous inflation of multiple airbags 2 on this side. At the same time, this structure also makes the clamping operation more convenient.

[0024] For ease of operation, this device also includes an adjustment unit, which comprises an upper support 6, a lower support 7, and an adjusting strut 8. The upper support 6 is installed on the outer side of the U-shaped plate 1, and the lower support 7 is located below and to the outside of the upper support 6, and can be fixed to the ground during installation. The two ends of the adjusting strut 8 are hinged to the upper support 6 and the lower support 7, respectively. The adjusting strut 8 includes two threaded rods 81 and a threaded sleeve 82 fitted between the two threaded rods 81. The ends of the two threaded rods 81 are hinged to the upper support 6 and the lower support 7, respectively. Thus, after hoisting, the length of the adjusting strut 8 can be adjusted by turning the threaded sleeve 82, thereby adjusting the position of the sandwich wall panel, achieving precise adjustment and installation of the sandwich wall panel, and controlling the verticality of the sandwich wall panel installation. In this embodiment, the adjustment unit can be installed on each clamping unit and can be arranged symmetrically on the left and right.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
