Description

Technical Field

[0001] This utility model relates to the field of high-rise cantilever curtain wall construction technology, and in particular to a high-rise cantilever curtain wall construction platform. Background Technology

[0002] For aesthetic purposes, high-rise buildings, often serving as landmarks, are typically designed with various types of cantilevered eaves, making them stand out among other buildings. The complex shapes of the eaves at the top of high-rise buildings, such as inverted staircase designs, increase with height, creating the illusion of a large hat. However, this design introduces significant challenges to construction, especially for curtain wall construction. For smaller overhangs, such as within 3 meters, a combination of traditional cantilevered I-beams and scaffolding can be used. However, as the height and span of the eaves increase, this traditional method becomes insufficient, necessitating the use of other specialized machinery. This significantly increases costs and construction difficulty, and also poses certain safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a construction platform for high-rise cantilever curtain walls. This construction platform effectively improves the efficiency and safety of curtain wall construction, reduces costs, and at the same time, combines BIM technology for accurate simulation to ensure precise control of the manufacturing and erection process, providing a relatively isolated and safe working platform for the construction of complex cantilever curtain walls in high-rise buildings.

[0004] To solve the above-mentioned technical problems, the present invention provides a high-rise cantilever curtain wall construction platform comprising vertical square steel pipes, horizontal cantilever steel beams, and telescopic adjustable steel diagonal braces. The vertical square steel pipes are vertically spaced between the top and bottom surfaces of the upper and lower structural edge beams on the outer edge of the building's top-floor structure. The horizontal cantilever steel beams are inserted into the vertical square steel pipes and are locked in place by fixing clamps on both sides of the vertical square steel pipes. The telescopic adjustable steel diagonal braces are located between the bottom end of the vertical square steel pipes and the cantilever end of the horizontal cantilever steel beams, and are supported by fastener steel pipes between the middle of the telescopic adjustable steel diagonal braces and the middle of the horizontal cantilever steel beams.

[0005] Furthermore, an upper tie rod is provided between the cantilever end of the horizontal cantilever steel beam and the upper structural side beam at the outer edge of the building's top-floor structure.

[0006] Furthermore, it also includes horizontal connecting steel beams, which are provided with intermittent insertion holes. The horizontal connecting steel beams are sequentially inserted into the insertion holes of the horizontal cantilever steel beams, and the horizontal cantilever steel beams and the horizontal connecting steel beams intersect to form a construction platform plane.

[0007] Furthermore, the connection nodes between the horizontal cantilever steel beam and the horizontal connecting steel beam are equipped with fixed clamps to lock their relative positions.

[0008] Furthermore, the surfaces of the horizontal cantilever steel beams and the horizontal connecting steel beams are fully covered with rigid cover plates.

[0009] Furthermore, the rigid cover plate is equipped with an inspection door via a hinge.

[0010] Because the construction platform for high-rise cantilever curtain walls of this utility model adopts the above-mentioned technical solution, namely, the vertical square steel pipes of this construction platform are vertically spaced between the top and bottom surfaces of the upper and lower structural edge beams on the outer edge of the top floor structure of the building, the horizontal cantilever steel beams are inserted into the vertical square steel pipes and fixed clamps are set on both sides of the vertical square steel pipes to lock the horizontal cantilever steel beams, the telescopic adjustable steel diagonal braces are set between the bottom end of the vertical square steel pipes and the cantilever end of the horizontal cantilever steel beams, and the middle part of the telescopic adjustable steel diagonal braces is set with fastener steel pipe support between the middle part of the horizontal cantilever steel beams and the middle part of the horizontal cantilever steel beams. This construction platform utilizes BIM modeling software to design and fabricate a bracket platform. Steel embedded parts, matching vertical square steel pipes, are installed at intervals on the top and bottom surfaces of the upper and lower structural beams along the outer edge of the building's top-floor structure. The bracket platform is then hoisted between the top and bottom surfaces of the upper and lower structural beams along the outer edge of the building's top-floor structure, and the vertical square steel pipes are welded to the steel embedded parts. Matching scaffolding is then erected on the bracket platform according to the curtain wall's shape. After the curtain wall installation is complete, the scaffolding is dismantled, the welds between the vertical square steel pipes and the steel embedded parts are cut, and the bracket platform is hoisted to the ground for disassembly and dismantling. This construction platform effectively improves the efficiency and safety of curtain wall construction, reduces costs, and, combined with BIM technology for precise simulation, ensures accurate control of the fabrication and erection process, providing a relatively isolated and safe working platform for the construction of complex cantilevered curtain walls in high-rise buildings.

Detailed Implementation

[0012] Implementation, for example Figure 1 and Figure 2As shown, the high-rise cantilever curtain wall construction platform of this utility model includes a vertical square steel pipe 1, a horizontal cantilever steel beam 2, and a telescopic adjustable steel diagonal brace 3. The vertical square steel pipe 1 is vertically spaced between the top and bottom surfaces of the upper and lower structural side beams 4 and 5 on the outer edge of the top floor structure of the building. The horizontal cantilever steel beam 2 is inserted into the vertical square steel pipe 1 and is locked by fixing clamps 21 on both sides of the vertical square steel pipe 1. The telescopic adjustable steel diagonal brace 3 is located between the bottom end of the vertical square steel pipe 1 and the cantilever end of the horizontal cantilever steel beam 2. A fastener steel pipe support 6 is provided between the middle of the telescopic adjustable steel diagonal brace 3 and the middle of the horizontal cantilever steel beam 2.

[0013] Preferably, an upper tie rod 7 is provided between the cantilever end of the horizontal cantilever steel beam 2 and the upper structural side beam 4 at the outer edge of the building's top-floor structure.

[0014] Preferably, it also includes a horizontal connecting steel beam 8, wherein the horizontal cantilever steel beam 2 is provided with insertion holes at intervals, and the horizontal connecting steel beam 8 is inserted into the insertion holes of the horizontal cantilever steel beam 2 in sequence, and the horizontal cantilever steel beam 2 and the horizontal connecting steel beam 8 intersect to form a construction platform plane.

[0015] Preferably, the connection node between the horizontal cantilever steel beam 2 and the horizontal connecting steel beam 8 is equipped with a fixing clamp 81 to lock their relative positions.

[0016] Preferably, the surfaces of the horizontal cantilever steel beam 2 and the horizontal connecting steel beam 8 are fully covered with rigid cover plates 9. The rigid cover plates enclose the construction platform, ensuring the safety of personnel working above; at the same time, they can also prevent items and debris from falling and affecting personnel on the ground during the construction of the upper cantilever curtain wall.

[0017] Preferably, the rigid cover plate 9 is equipped with an inspection door 91 via a hinge. The inspection door is used for reinforcement, disassembly, and adjustment of the lower diagonal brace.

[0018] A method for erecting a construction platform for a high-rise cantilevered curtain wall includes the following steps: Step 1: Based on the high-rise cantilevered curtain wall, design and manufacture the bracket platform using BIM modeling software tools, perform stress analysis on the telescopic adjustable steel diagonal brace 3 and the upper tie rod 7, and determine the optimal support angle. Step 2: Install steel embedded parts 41 and 51, which are matched with vertical square steel pipe 1, at intervals on the top and bottom surfaces of the upper and lower structural edge beams 4 and 5 on the outer edge of the building's top-floor structure. Step 3: Install pulley hoists on the main beam structure of the system curtain wall to be constructed, and set up lifting points on the bracket platform according to the stress analysis calculation. Use pulley hoists and lifting points to lift the bracket platform, which has been assembled on the ground, to the top and bottom surfaces of the upper and lower structural edge beams 4 and 5 on the outer edge of the building's top floor structure. Step 4: Weld the vertical square steel pipe 1 of the bracket platform to the steel embedded parts 41 and 51 on the upper and lower parts of the building's top structure, so that the bracket platform is fixed to the edge of the building's top structure, forming a complete outward cantilevered bracket platform. Step 5: On the bracket platform, a construction scaffold 10 matching the complex shape of the high-rise cantilever curtain wall is erected using steel pipes. A positioning structure 102 is set at the part where the vertical steel pipe 101 of the scaffold 10 contacts the bracket platform. The top of the scaffold 10 is close to the curtain wall construction area. Step 6: After the curtain wall installation is completed, first dismantle the scaffolding 10, then cut off the weld between the vertical square steel pipe 1 and the steel embedded parts 41 and 51, then hoist the bracket platform to the ground, and finally dismantle it.

[0019] After the construction platform is installed, a matching working scaffold is erected according to the shape of the curtain wall. This method of setting up the construction platform and the working scaffold separately makes the construction platform versatile, while the working scaffold can adapt to various shapes of curtain walls. The combination of the two can better meet the construction needs of various high-rise complex cantilever curtain walls.

[0020] Preferred, such as Figure 3 As shown, the positioning structure 102 includes a clamp 103 and a short connecting pipe 104 disposed on the top surface of the clamp 103. The clamp 103 is disposed on the horizontal cantilever steel beam 2 or the horizontal connecting steel beam 8 of the support platform. The vertical steel pipe 101 of the scaffold 10 is inserted into the short connecting pipe 104. The positioning structure prevents the scaffold from slipping.

[0021] Preferably, when the span of the cantilevered curtain wall to be constructed changes, the width of the bracket platform can be changed by altering the length and angle of the telescopic adjustable steel diagonal brace 3 to meet the needs of different curtain wall construction operation widths.

[0022] Preferably, the scaffolding 10 is a disc-lock scaffolding or a coupler-type steel pipe scaffolding frame.

[0023] This method involves fabricating a support platform directly beneath the large cantilevered curtain wall. Constructed from high-strength steel, it ensures stability and reliability. Adjustable support rods are installed at the bottom of the support platform, allowing for width adjustment by changing the angle and extension length as needed. Lightweight materials are used for the cantilever section, reducing overall weight and improving the ease of curtain wall construction. The support platform is assembled and disassembled on the ground, reducing high-altitude work and improving safety. Furthermore, this construction platform primarily uses mechanical assembly with minimal welding, reducing environmental pollution compared to traditional methods and protecting the health of workers. The rigid cover plates laid must meet the load-bearing requirements of workers; the material specifications are determined by calculation. If requirements are not met, stiffening plates are installed or the walkway is replaced with metal walkway panels. This construction platform and its erection method provide a relatively isolated and safe working platform for the construction of complex high-rise cantilevered curtain walls.
