Description

Technical Field

[0001] This invention relates to the field of curtain wall construction technology, specifically to a lightweight hoisting platform based on a tensioned structure and a construction method for roof curtain wall construction. Background Technology

[0002] Due to the complex and diverse structural requirements of aluminum panel curtain walls for roofs, suspended scaffolds are often used during construction. These scaffolds transport workers and materials to the work area. However, existing suspended scaffolds have relatively poor overturning resistance, posing certain safety hazards. Furthermore, the single lifting capacity of the scaffold is relatively small, and the work coverage area is limited, restricting the construction area at any given time and reducing construction efficiency. Summary of the Invention

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

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lightweight hoisting platform based on a tensioned structure for roof curtain wall construction includes hoisting ropes, a supporting body, auxiliary support components, platform plates, a bottom support component, and a protective fence. The top ends of multiple hoisting ropes are attached to the main body of the aluminum roof curtain wall, and the bottom ends of multiple hoisting ropes are connected to the supporting body. Multiple auxiliary support components are fixedly mounted on the supporting body. Multiple platform plates are mounted on the supporting body and auxiliary support components. The bottom support component is located at the bottom of the supporting body to improve its load-bearing capacity. The protective fence is located on the outer circumferential side of the supporting body.

[0006] Preferably, the supporting body is a frame structure spliced ​​together from multiple steel square tubes.

[0007] Preferably, the bottom support component includes support rods and cables. Multiple support rods are fixedly installed at the bottom of the auxiliary support or the support body, and the cables connect the support rods to the support body or connect two connected support rods.

[0008] Preferably, four support rods are provided at the bottom of the auxiliary support member. The four support rods are connected in sequence by four cables, and each support rod is connected to the edge of the adjacent support body by two cables.

[0009] Preferably, a support rod is provided at the bottom center of the support body, and the support rod is connected to the four sides of the support body by four cables.

[0010] Preferably, the platform board is a wooden template.

[0011] Preferably, a counterweight is provided on the support body.

[0012] A construction method for a lightweight hoisting platform based on a tensioned cable structure for roof curtain wall construction includes: Step 1, platform assembly: First, the main support body is assembled on-site according to the dimensions, and then auxiliary support components are assembled on the main support body; Next, the bottom support components are installed, and while tightening the cables, counterweights are installed on the main support body; Next, the platform panels are installed and fixed; Finally, the protective railing is installed.

[0013] Step two, platform hoisting: After the platform is assembled on the ground and passes inspection, slings are installed at the center of the four sides of the platform, and it is hoisted by a tower crane; after hoisting to the installation height, the hoisting ropes located at the four corners of the supporting body are connected to the bottom of the roof aluminum panel curtain wall body; the four slings are disassembled, and finally the remaining hoisting ropes are connected to the roof aluminum panel curtain wall body.

[0014] Step 3: Platform relocation. After hoisting, operators carry out construction work on the platform. Once the corresponding area of ​​the platform is completed, the slings are first installed at the middle of the four sides of the platform. All supporting structures are dismantled, and the platform is hoisted to the ground as a whole using a tower crane and four slings. The inspection personnel conduct an overall safety inspection of the platform. After passing the inspection, it is hoisted to the next work area until the curtain wall construction is completed.

[0015] In this invention, the device employs multiple lifting ropes for hoisting, providing multiple hoisting points and ensuring uniform hoisting force and stable operation. The included bottom support component increases the structural strength and load-bearing capacity of the support structure, allowing for a larger area and wider operational coverage. The bottom support component utilizes a tensioned cable structure combining support rods and cables, facilitating assembly and disassembly. Auxiliary support components and platform plates are assembled onto the support structure, simplifying disassembly and assembly. The overall structure is lightweight, further enhancing the hoisting load-bearing capacity. Attached Figure Description

Specific embodiments

[0023] The following further describes the present invention in conjunction with the attached drawings:

[0024] As Figures 1 to 5 shown, a lightweight hoisting platform based on a cable-strut structure for roof curtain wall construction includes a hoisting rope 1, a support main body 2, an auxiliary support member 3, a platform board 4, a bottom support member 5 and a protective fence 6. A plurality of hoisting ropes 1 are provided, and the tops of the plurality of hoisting ropes 1 are arranged on the main body 7 of the roof aluminum plate curtain wall, and the bottoms of the plurality of hoisting ropes 1 are connected to the support main body 2.

[0025] In this embodiment, the support main body 2 is a frame structure formed by splicing a plurality of steel square tubes, and the support main body 2 is in an overall shape of a "field" character. The plurality of steel square tubes are spliced into a whole by welding. Of course, the plurality of steel square tubes 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 accommodate 5 operators at the same time, and 1000 kg of aluminum plates and steel keels can be placed on the platform.

[0026] A plurality of auxiliary support members 3 are fixedly arranged on the support main body 2. The auxiliary support members 3 are steel square steels 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. A plurality of platform boards 4 are arranged on the tops of the support main body 2 and the auxiliary support members 3. The platform board 4 is a wooden template. The wooden template is laid on the tops of the support main body 2 and the auxiliary support members 3, and the wooden template is connected to the support main body 2 and the auxiliary support members 3 by steel wires for reinforcement.

[0027] 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 a plurality of support rods.

[0028] A bottom support component 5 is installed at the bottom of the support body 2 to improve its load-bearing capacity. The bottom support component 5 includes support rods 50 and cables 51. Multiple support rods 50 are fixedly installed at the bottom of the auxiliary support component 3 or the support body 2. The cables 51 connect the support rods 50 to the support body 2 or connect two connected support rods 50. The bottom support component 5 increases the overall structural strength of the platform without adding excessive weight, enabling the platform to have a larger working surface, increasing the coverage area of ​​a single operation, and improving the convenience and efficiency of construction.

[0029] Suspended platforms can transport construction personnel and materials to the work area, but existing suspended platforms have relatively poor overturning resistance, posing certain safety hazards. Furthermore, the lifting capacity of a single suspended platform is relatively small, and the work coverage area is limited, restricting the construction area at any given time and reducing construction efficiency.

[0030] In this embodiment, four support rods 50 are installed at the bottom of the auxiliary support member 3. The four support rods 50 are connected sequentially by four cables 51, and each support rod 50 is connected to the edge of the adjacent support body 2 by two cables 51. A support rod 50 is installed at the bottom center of the support body 2, and the support rod 50 is connected to the four sides of the support body 2 by four cables 51. When the bottom support member 5 is installed, a counterweight 8 is installed on the support body 2, and the stability of the entire platform is adjusted by the weight and position of the counterweight 8.

[0031] After the platform is installed on the main body 7 of the roof aluminum panel curtain wall using hoisting rope 1, the supporting body 2 is reinforced and connected to the main body 7 of the roof aluminum panel curtain wall using reinforcing connecting rod 9, which further improves the stability of the platform during use.

[0032] Soft rubber bodies are fixed at the four corners and front of the supporting main body 2 to prevent the platform from damaging the construction surface when it swings. Safety ropes and self-locking devices are installed on the main body 7 of the roof aluminum panel curtain wall. One end of the safety rope is connected to the operator. In the event of an accidental fall of the platform, the safety rope and self-locking device provide additional safety assurance for the operator.

[0033] When the hoisting platform is located in the middle position below the main body 7 of the aluminum panel curtain wall on the roof, eight hoisting ropes 1 are installed. The eight hoisting ropes 1 are arranged around the circumference of the supporting main body 2, such as... Figure 1 As shown. This is the first state of the hoisting platform installation.

[0034] When the hoisting platform is located at the edge below the main body 7 of the roof aluminum panel curtain wall, eleven hoisting ropes 1 are installed, eight of which are vertically installed and the other three are inclined, so that one end of the supporting body 2 cantilevered on the outside of the main body 7 of the roof aluminum panel curtain wall, extending the operating space, such as... Figure 4As shown, the three inclined lifting ropes 1 share a top lifting point with the adjacent vertically arranged lifting ropes 1. This is the second state of the lifting platform installation.

[0035] When the hoisting platform is located at the corner below the main body 7 of the roof aluminum panel curtain wall, fourteen hoisting ropes 1 are installed, eight of which are vertically installed and the other six are inclined, so that one corner of the supporting body 2 cantilevered outside the corresponding corner of the main body 7 of the roof aluminum panel curtain wall, extending the operating space, such as... Figure 5 As shown, two lifting ropes 1 are inclinedly installed on both sides corresponding to the corner. The four inclined lifting ropes 1 share a top lifting point with the adjacent vertically installed lifting rope 1. At the corresponding position of the corner, two lifting ropes 1 are inclinedly installed, and these two lifting ropes 1 share a top lifting point with the vertically installed lifting rope 1 at the corresponding position of the corner. This state is the third state of the lifting platform installation.

[0036] like Figures 1 to 6 The method shown is a construction method for a lightweight hoisting platform based on a tensioned structure for roof curtain wall construction, the method comprising:

[0037] Step 1: Platform assembly. First, assemble the main support body 2 on-site according to the dimensions, and then assemble the auxiliary support components 3 onto the main support body 2. Next, install the bottom support components 5, tighten the cables 51, and install the counterweights 8 on the main support body 2. Then, install and fix the platform plate 4. Finally, install the protective fence 6.

[0038] Step 2: Platform hoisting. After the platform is assembled on the ground and passes inspection, slings are installed at the center of the four sides of the platform, and it is hoisted by a tower crane. After hoisting to the installation height, the hoisting ropes located at the four corners of the supporting body 2 are connected to the bottom of the roof aluminum panel curtain wall body 7. The four slings are disassembled, and finally the remaining hoisting ropes are connected to the roof aluminum panel curtain wall body 7.

[0039] Step 3: Platform relocation. After hoisting, operators carry out construction work on the platform. Once the corresponding area of ​​the platform is completed, the slings are first installed at the middle of the four sides of the platform, all supporting main bodies 2 are dismantled, and the platform is hoisted to the ground as a whole using a tower crane and four slings. The inspection personnel conduct an overall safety inspection of the platform. After passing the inspection, it is hoisted to the next work area until the curtain wall construction is completed.

[0040] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.

[0041] During the actual construction, the main body of the aluminum panel curtain wall on the roof was divided into 18 areas and constructed in a sequential manner, such as... Figure 6As shown. Among them, the areas corresponding to serial numbers 1, 6, 13 and 18 use the third state lifting platform, the areas corresponding to serial numbers 8, 9, 10 and 11 use the first state lifting platform, and the remaining areas use the second state lifting platform.
