Description

Technical Field

[0001] The utility model belongs to the field of construction of villas with special roofs, and in particular relates to a special hanging device for arc-shaped templates used for arc-shaped roof construction. Background Art

[0002] The curved roof is a special building structure with unique aesthetics and design effects. At present, in order to improve construction efficiency during the construction process, we use 3D printing technology to manufacture curved templates that adapt to complex curved surface changes according to the design requirements of the curved roof. The curved template is used for one-time concrete pouring. This method reduces the time and process complexity of traditional wooden template assembly and improves construction efficiency.

[0003] Traditional slings are often designed to lift goods of regular shapes. For arc-shaped templates with irregular shapes and complex curves, during the lifting process, since the arc-shaped template has no obvious fulcrum, the contact area between the sling and the arc-shaped template may be small, the pressure is concentrated, and the arc-shaped template may be easily damaged.

[0004] Therefore, we propose a special hanging device for curved formwork used in curved roof construction to solve the above problems. Utility Model Content

[0005] In view of the problem that during the lifting process of traditional hoists, since the arc formwork has no obvious fulcrum, the contact area between the hoist and the arc formwork is small, the pressure is concentrated, and the arc formwork is easily damaged, the utility model provides a special hoist for the arc formwork for arc roof construction.

[0006] The utility model solves the technical problem by adopting the following scheme: a special hanging device for arc formwork used for arc roof construction, comprising a crossbeam and two sets of hanging units, wherein the hanging units comprise a frame and N sets of adjusting parts, a sliding sleeve is welded on the top of the frame, and the sliding sleeve can slide laterally along the crossbeam;

[0007] N groups of adjusting parts are installed at the bottom of the frame in sequence from front to back, and a supporting rod for supporting the arc template is installed at the bottom end of the adjusting part.

[0008] Preferably, a lifting lug is installed on the top of the crossbeam.

[0009] Preferably, a plurality of positioning holes are respectively provided at both ends of the crossbeam, a threaded hole is provided at the top of the sliding sleeve, and the same positioning screw is provided in the threaded hole and the corresponding positioning hole.

[0010] Preferably, the adjusting member is an adjusting screw, which is threadedly connected to a nut installed at the bottom of the frame.

[0011] Preferably, a positioning piece for pressing down the arc-shaped template is threadedly connected to the adjusting screw rod, and the positioning piece is located above the supporting rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By rotating the adjusting screw rod one by one, the heights of multiple supporting rods are adjusted one by one, so that multiple supporting rods are all attached to the curved surface of the arc-shaped template, providing multi-point support for the arc-shaped template and providing uniform supporting force, avoiding the problem of damage to the arc-shaped template during the hoisting process, and the height of each supporting rod can be freely adjusted to adapt to arc-shaped templates with different radian, improving the practicability and applicability of the device.

[0014] 2. By rotating the positioning piece, the positioning piece is brought into contact with the upper arc surface of the arc-shaped template to press down and fix the arc-shaped template, ensuring the stability and safety of the arc-shaped template during the hoisting process.

[0018] The present utility model will be further described below with reference to the drawings and embodiments.

[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution for a special lifting device for an arc-shaped template in the construction of an arc-shaped roof:

[0020] Embodiment 1:

[0021] According to Figure 1 and Figure 2 shown, it includes a cross beam 3 and two groups of hoisting units. A lifting lug 5 is installed on the top of the cross beam 3, and the lifting lug 5 is connected to the hook of the lifting equipment.

[0022] The hoisting unit includes a frame 1 and N groups of adjusting members. A sliding sleeve 41 is welded on the top of the frame 1. The sliding sleeve 41 can slide horizontally along the cross beam 3. A plurality of positioning holes 31 are respectively opened at both ends of the cross beam 3. A threaded hole is opened at the top of the sliding sleeve 41. The same positioning screw rod 42 is arranged in the threaded hole and the corresponding positioning hole 31 to fix the position of the sliding sleeve 41 and make the sliding sleeve 41 stop sliding.

[0023] In this embodiment, the number of a set of adjusting members is six. The adjusting members are adjusting screws 21. The six adjusting screws 21 are arranged in sequence from front to back. The adjusting screws 21 are threadedly connected to nuts 22 installed at the bottom of the frame 1. A support rod 24 for supporting the arc-shaped template 6 is installed at the bottom end of the adjusting screw 21. By rotating the adjusting screws 21 one by one, the heights of the multiple support rods 24 are adjusted one by one, so that the multiple support rods 24 are all in contact with the curved surface of the arc-shaped template 6, providing multi-point support for the arc-shaped template 6 and providing uniform supporting force to avoid the problem of damage to the arc-shaped template 6 during the hoisting process. Moreover, the height of each support rod 24 can be freely adjusted to adapt to arc-shaped templates 6 with different radian, improving the practicability and applicability of the device.

[0024] A positioning piece 23 for pressing down the arc-shaped template 6 is threadedly connected to the adjusting screw 21. The positioning piece 23 is located above the support rod 24. By rotating the positioning piece 23, the positioning piece 23 is brought into contact with the upper arc surface of the arc-shaped template 6 to press and fix the arc-shaped template 6, ensuring the stability and safety of the arc-shaped template 6 during the hoisting process.

[0025] During specific use, for a special lifting tool for an arc-shaped template for arc-shaped roof construction of the present utility model, first connect the lifting lugs 5 to the hooks of the lifting equipment, then place the arc-shaped template 6 between the two sets of hoisting units, and then rotate the adjusting screws 21 one by one to adjust the heights of the multiple support rods 24 one by one, so that the multiple support rods 24 are all in contact with the curved surface of the arc-shaped template 6 to provide multi-point support for the arc-shaped template 6. Finally, rotate the positioning pieces 23 one by one to make the positioning pieces 23 contact the upper arc surface of the arc-shaped template 6 to press and fix the arc-shaped template 6, ensuring the stability of the arc-shaped template 6 during the hoisting process.
