Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall construction, and in particular to a lightweight hoisting platform based on a string structure for roof curtain wall construction and a construction method. Background Art

[0002] Due to the complex and diverse requirements of building structures, rooftop aluminum curtain walls are often constructed using hanging baskets, which transport workers and materials to the work area. However, existing hanging baskets have relatively poor anti-overturning capabilities, posing certain safety risks. Furthermore, the single lifting capacity of the hanging baskets is relatively small, and the operating range is small, which limits the single construction area and reduces construction efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a lightweight hoisting platform based on a string structure for roof curtain wall construction and a construction method. The platform is used to solve the problems of poor stability, small single hoisting volume, small operation coverage and low construction efficiency in the existing technology of roof curtain wall construction.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A lightweight lifting platform based on a cable-stayed structure for roof curtain wall construction includes lifting ropes, a supporting body, auxiliary supporting parts, a platform plate, a bottom supporting member and a protective fence. The top ends of multiple lifting ropes are arranged on the roof aluminum plate curtain wall body, and the bottom ends of multiple lifting ropes are connected to the supporting body; multiple auxiliary supporting parts are fixedly arranged on the supporting body; multiple platform plates are arranged on the supporting body and the auxiliary supporting parts; the bottom supporting member is arranged at the bottom of the supporting body to improve the bearing capacity of the supporting body; and the protective fence is arranged on the outer circumference of the supporting body.

[0005] Preferably, the supporting body is a frame structure formed by splicing a plurality of steel square tubes.

[0006] Preferably, the bottom support member includes support rods and cables, and a plurality of the support rods are fixedly arranged at the bottom of the auxiliary support member or the support body, and the cables connect the support rods to the support body or connect two connected support rods.

[0007] Preferably, four support rods are provided at the bottom of the auxiliary support member, and the four support rods are sequentially tied together by four cables, and each support rod is tied together with the edge of the adjacent support body by two cables.

[0008] Preferably, a support rod is provided at the middle bottom of the support body, and the support rod is connected to the four sides of the support body by four cables.

[0009] Preferably, the platform board is a wooden formwork.

[0010] Preferably, a counterweight is provided on the support body.

[0011] A construction method for a lightweight hoisting platform based on a string structure for roof curtain wall construction includes: step 1, platform assembly, firstly, assembling the support body on site according to the size, and then assembling the auxiliary support members on the support body; then installing the bottom support member, while tightening the cable, installing the counterweight block on the support body; then installing the platform board and fixing it; and finally installing the protective fence; Step 2: Platform hoisting. After the platform is assembled on the ground and passed the acceptance inspection, install slings in the middle of the four sides of the platform and lift it with a tower crane. After lifting it to the installation height, connect the hoisting ropes at the four corners of the support body to the bottom of the roof aluminum curtain wall body. Remove the four slings and finally connect the remaining hoisting ropes to the roof aluminum curtain wall body. Step three: After the platform is moved and hoisted, the operator will carry out construction work on the platform. When the construction of the corresponding area of ​​the platform is completed, first connect the four sides of the platform to the middle position to install the slings, remove all supporting bodies, and lift the entire platform to the ground through the tower crane and four slings. The inspection personnel will conduct an overall safety inspection of the platform. If it passes the inspection, it will be hoisted to the next work area until the curtain wall construction is completed.

[0012] In the present invention, the device as a whole utilizes multiple lifting ropes for lifting, with multiple lifting points, providing uniform lifting force to the support body and ensuring stable lifting. The bottom support member increases the structural strength of the support body, improving its bearing capacity, allowing the support body to be expanded and improving the scope of operation. The bottom support member utilizes a string-like structure composed of support rods and cables, facilitating assembly and disassembly. The auxiliary support members and platform plate are assembled on the support body, facilitating assembly and disassembly. The overall structure is lightweight and increases the lifting capacity.

Specific implementation manner

[0014] The following further describes the present invention in conjunction with the accompanying drawings: As Figures 1 to 5 A lightweight hoisting platform based on a cable-strut structure for roof curtain wall construction as shown, including hoisting ropes 1, support main body 2, auxiliary support members 3, platform boards 4, bottom support members 5 and protective fences 6. Multiple hoisting ropes 1 are provided, and the tops of the multiple hoisting ropes 1 are arranged on the main body 7 of the roof aluminum plate curtain wall, and the bottoms of the multiple hoisting ropes 1 are connected to the support main body 2.

[0015] In this embodiment, the support main body 2 is a frame structure formed by splicing multiple steel square pipes, and the support main body 2 is in a "field" shape as a whole. The multiple steel square pipes are spliced into a whole by welding. Of course, the multiple steel square pipes can also be assembled into a whole by right-angle connectors, T-shaped connectors and cross-shaped connectors. The overall size of the support main body 2 is 8160mm×8160mm. This platform can have 5 operators at the same time, and 1000 kg of aluminum plates and steel keels can be placed on the platform.

[0016] Multiple auxiliary support members 3 are fixedly arranged on the support main body 2. The auxiliary support members 3 are steel square steel or scaffolding steel pipes, and the auxiliary support members 3 are fixedly connected to the support main body 2 through U-shaped connectors and nuts. Multiple platform boards 4 are arranged on the tops of the support main body 2 and the auxiliary support members 3. The platform boards 4 are wooden templates. The wooden templates are laid on the tops of the support main body 2 and the auxiliary support members 3, and the wooden templates are connected to the support main body 2 and the auxiliary support members 3 by steel wires for reinforcement.

[0017] The protective fence 6 is arranged on the outer circumference of the support main body 2. The protective fence 6 is used to improve the safety of construction workers. The protective fence 6 includes a support rod fixedly installed on the top of the support main body 2 and a protective rope connecting several support rods.

[0018] The bottom support member 5 is arranged at the bottom of the support main body 2 to improve the bearing capacity of the support main body 2. The bottom support member 5 includes a support rod 50 and a cable 51. Multiple support rods 50 are fixedly arranged at the bottom of the auxiliary support member 3 or the support main body 2, and the cable 51拉结 the support rod 50 and the support main body 2 or拉结 two adjacent support rods 50. The bottom support member 5 increases the overall structural strength of the platform without adding too much weight, enabling the platform to have a larger working surface, improving the single-operation coverage range, and improving the construction convenience and construction efficiency.

[0019] Suspended baskets can transport construction workers and materials to the work area, but existing suspended baskets have relatively poor anti-overturning capabilities, posing certain safety risks. Furthermore, the single lifting capacity of the suspended basket is relatively small, and the working area is small, which limits the single construction area and reduces construction efficiency.

[0020] In this embodiment, four support rods 50 are installed at the bottom of the auxiliary support member 3. These four support rods 50 are sequentially connected by four cables 51. Each support rod 50 is further connected to the edge of the adjacent support body 2 by two cables 51. A support rod 50 is installed at the center bottom of the support body 2 and is connected to the four edges of the support body 2 by four cables 51. When the bottom support member 5 is installed, a counterweight 8 is placed on the support body 2. The weight and position of the counterweight 8 adjust the stability of the entire platform.

[0021] After the platform is installed on the roof aluminum plate curtain wall body 7 through the lifting rope 1, the support body 2 and the roof aluminum plate curtain wall body 7 are reinforced and connected by the strengthening connecting rod 9 to further improve the stability of the platform during use.

[0022] Soft gels are fixed to the four corners and the front of the support body 2 to prevent the platform from damaging the construction surface when it swings. A safety rope and a self-locking device are installed on the roof aluminum curtain wall body 7. One end of the safety rope is connected to the operator. When the platform accidentally falls, the safety rope and self-locking device provide additional safety guarantees for the operator.

[0023] When the hoisting platform is located in the middle position below the roof aluminum curtain wall body 7, eight hoisting ropes 1 are provided, and the eight hoisting ropes 1 are arranged along the circumference of the support body 2, such as Figure 1 This state is the first state of the hoisting platform installation.

[0024] When the hoisting platform is located at the edge below the main body 7 of the roof aluminum curtain wall, eleven hoisting ropes 1 are provided, eight of which are vertically arranged and the other three are inclined, so that one end of the supporting body 2 is cantilevered outside the main body 7 of the roof aluminum curtain wall, extending the operating space. Figure 4 As shown, three inclined hoisting ropes 1 share a top hoisting point with adjacent vertically arranged hoisting ropes 1. This state is the second state of the hoisting platform installation.

[0025] When the hoisting platform is located at the corner position below the roof aluminum curtain wall body 7, fourteen hoisting ropes 1 are set, eight of which are vertically set and the other six are inclined, so that one corner of the support body 2 cantilevers outward from the corresponding corner of the roof aluminum curtain wall body 7, extending the operating space. Figure 5As shown, two lifting ropes 1 are installed at an angle on either side of the corner. The four inclined lifting ropes 1 share a top lifting point with the adjacent vertically installed lifting ropes 1. Two lifting ropes 1 are installed at an angle at the corresponding position of the corner. The two lifting ropes 1 share a top lifting point with the one vertically installed lifting rope 1 at the corresponding position of the corner. This state is the third state of the lifting platform installation.

[0026] like Figures 1 to 6 A construction method of a lightweight hoisting platform based on a string structure for roof curtain wall construction is shown, and the construction method includes: Step 1: Assemble the platform. First, assemble the support body 2 on site according to the size, then assemble the auxiliary support 3 on the support body 2; then install the bottom support member 5, tighten the cable 51, and install the counterweight 8 on the support body 2; then install the platform board 4 and fix it; finally, install the protective fence 6; Step 2: Platform hoisting. After the platform is assembled on the ground and passed the acceptance inspection, install slings in the middle of the four sides of the platform and lift it with a tower crane. After lifting it to the installation height, connect the hoisting ropes at the four corners of the support body 2 to the bottom of the roof aluminum curtain wall body 7. Remove the four slings and finally connect the remaining hoisting ropes to the roof aluminum curtain wall body 7. Step three: The platform is moved. After the hoisting is completed, the operator performs construction work on the platform. When the construction of the corresponding area of ​​the platform is completed, first connect the four sides of the platform to the middle position to install the slings, remove all the supporting bodies 2, and lift the entire platform to the ground through the tower crane and four slings. The inspection personnel conduct an overall safety inspection of the platform, and after passing the inspection, it will be hoisted to the next work area until the curtain wall construction is completed.

[0027] The above embodiments are merely some explanations of the concept and implementation of the present invention, and are not intended to limit the same. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.

[0028] During the specific construction, the main body of the roof aluminum curtain wall is divided into 18 areas for flow construction, such as Figure 6 The areas corresponding to numbers 1, 6, 13 and 18 use the hoisting platform in the third state, the areas corresponding to numbers 8, 9, 10 and 11 use the hoisting platform in the first state, and the remaining areas use the hoisting platform in the second state.
