Description

Technical Field

[0001] This utility model relates to a material transport platform used in the construction of high-rise buildings, and particularly to a modularly assembled high-altitude cantilever material transport platform that can be easily installed, dismantled, and reused. Background Technology

[0002] In the construction of high-rise buildings, the construction materials required for the upper floors need to be transported to the upper floors by hoisting. The existing technology is to erect a cantilevered platform extending from the floor slab outside the upper floors. The tower crane first lifts the construction materials to the cantilevered platform, and then the construction workers move the construction materials from the cantilevered platform to the upper floors. As the building rises, the cantilevered platform needs to be disassembled and transported to higher floors for repeated construction. This has the drawback of being cumbersome to disassemble and assemble. In particular, the cantilevered platform extending to the outside of the building usually requires diagonal bracing to ensure the stability of the platform portion. The inner end of the diagonal bracing needs to be fixed to the wall outside the building with expansion bolts, which is difficult and dangerous to construct on the outside of the building and can also damage the building walls. How to develop a modular high-altitude cantilevered material transport platform that is easy to assemble and disassemble and avoids damage to the building structure has become an urgent problem to be solved on site. Summary of the Invention

[0003] This invention provides a reusable, modularly assembled, high-altitude cantilevered material transport platform, solving the technical problem of how to develop a high-altitude cantilevered material transport platform that is easy to assemble and disassemble and avoids damage to the building structure.

[0004] This utility model solves the above technical problems through the following technical solution: A modularly assembled, reusable, and easily assembled high-altitude cantilevered material transport platform includes a floor slab, an exterior wall, an L-shaped steel backrest, diagonal braces, I-beam cantilever beams, channel steel cantilever beams, and triangular fasteners. The L-shaped steel backrest is movably positioned at the 90-degree connection between the floor slab and the exterior wall. Pre-embedded bolts are embedded in the floor slab, and through-holes for these bolts are provided on the horizontal plate of the L-shaped steel backrest. Two I-beam cantilever beams are positioned parallel to each other on the floor slab and cantilever beyond the floor slab. Channel steel cantilever beams are connected to the top surfaces of the I-beam cantilever beams. Diagonal braces are connected to the lower outer ends of the two I-beam cantilever beams, and the other ends of the diagonal braces are fixedly connected to the L-shaped steel backrest via bases at their lower ends. On the vertical plate: A vertical plate is fixedly connected to the vertical right-angle side of the triangular fastener, forming a 90-degree angle with the triangular main body plate of the triangular fastener. A through hole for vertical plate bolts is provided on the vertical plate. A horizontal plate is fixedly connected to the horizontal right-angle side of the triangular fastener, forming a 90-degree angle with the triangular main body plate of the triangular fastener. A through hole for horizontal plate bolts is provided on the horizontal plate. Through holes are provided at equal intervals on the web of the I-beam cantilever beam. Triangular fasteners are correspondingly provided on both sides of the through holes. The through holes for vertical plate bolts of the triangular fasteners correspond to the through holes. Connecting bolts pass between corresponding vertical plate bolt through holes and through holes. The through holes for horizontal plate bolts on the horizontal plate of the triangular fasteners are connected to pre-embedded bolts.

[0005] A cargo flatbed trolley is movably mounted on the two channel steel cantilever beams. The cargo flatbed trolley has wheels on its underside, which are movably mounted in the upward U-shaped slots of the channel steel cantilever beams. A traction rope is connected to the inner end of the cargo flatbed trolley.

[0007] This utility model allows for modular assembly of various components on-site, enabling the rapid construction of a cantilevered platform for transporting goods on the floor slab. This eliminates the need for drilling holes in the exterior wall to fix the platform's diagonal braces, thus avoiding damage to the floor slab's structure. The entire platform is assembled on-site from multiple components and can be securely fixed to the floor slab and the exterior wall of the building, facilitating the transfer of hoisted materials. Once the hoisting task on this floor is completed, the platform can be quickly disassembled and transferred to the next floor slab for reassembly. Attached Figure Description

Then, two I-beam cantilever beams 6 are installed on the horizontal plate of the L-shaped steel backing plate 3. The two I-beam cantilever beams 6 are set parallel to each other on the floor slab 1 and cantilevered outside the floor slab 1. A channel steel cantilever beam 7 is connected to the top surface of the I-beam cantilever beam 6.

The triangular fasteners 12 are fixed on the pre-embedded bolts 18. The I-beam cantilever beam 6 is fixed to the floor slab 1 by clamping and fixing the two triangular fasteners 12. At the same time, the triangular fasteners 12 also press and fix the L-shaped steel backing plate 3 below it.

[0010] A cargo flatbed trolley 9 is movably mounted on the two channel steel cantilever beams 7. A traveling wheel 10 is mounted on the underside of the cargo flatbed trolley 9. The traveling wheel 10 is movably mounted in the upward U-shaped groove of the channel steel cantilever beam 7. A traction rope 11 is connected to the inner end of the cargo flatbed trolley 9. Through the action of the traction rope 11, the cargo flatbed trolley 9 can move along the channel steel cantilever beam 7 to transport the goods on the cantilever platform into the floor slab 1.

[0011] The channel steel cantilever beam 7 is fixed to the top surface of the I-beam cantilever beam 6 by connecting screws 19; an anti-detachment baffle 8 is provided at the outer end of the channel steel cantilever beam 7 to prevent the flatbed truck 9 from falling off; the outer end of the diagonal brace 4 is connected to the lower surface of the outer end of the I-beam cantilever beam 6 by the upper base 20.

[0012] The on-site assembly process of this utility model is as follows: Step 1: Fix the channel steel cantilever beam 7 to the top surface of the I-beam cantilever beam 6 using connecting screws 19 to complete the assembly of the two parallel tracks; The second step is to place the assembled two parallel tracks on the horizontal plate of the L-shaped steel backing plate 3; then, connect the outer end of the diagonal brace 4 to the lower surface of the outer end of the I-beam cantilever beam 6 through the upper base 20, and fix the other end of the diagonal brace 4 to the vertical plate of the L-shaped steel backing plate 3 through the lower base 5 of the diagonal brace. The third step is to move the L-shaped steel backing plate 3 and the two parallel tracks, which are connected by the diagonal bracing rod 4, to the 90-degree connection between the floor slab 1 and the exterior wall 2 of the building, and to make the L-shaped steel backing plate 3 close to the 90-degree corner, so that the exterior wall 2 of the building can form support for the two parallel tracks through the diagonal bracing rod 4. The fourth step is to arrange triangular fasteners 12 at intervals on the left and right sides of each I-beam cantilever beam 6, and to arrange the two triangular fasteners 12 on the left and right sides of the through holes 21 on the web of the I-beam cantilever beam 6, and to fasten and clamp the two corresponding triangular fasteners 12 and the web of the I-beam cantilever beam 6 together by connecting bolts 17. Step 5: Drill bolt connection holes on the horizontal plate of the L-shaped steel backing plate 3 below the horizontal plate bolt through hole 16 set on the horizontal plate 15 of the triangular fastener 12, and drill these holes into the floor slab. Connect the expansion bolts to the horizontal plate bolt through hole 16 and the drilled holes to achieve the purpose of anchoring the triangular fastener 12 to the floor slab 1. Another option is to pre-embed four rows of pre-embedded bolts 18 on the floor slab 1 according to the pre-installation position of the I-beam cantilever beam 6. In this step, it is only necessary to connect the horizontal plate bolt through holes 16 on the horizontal plate of the L-shaped steel backing plate 3 and the horizontal plate of the triangular fastener 12 to the pre-embedded bolts 18, and then tighten the nuts to complete the anchoring of the triangular fastener 12 to the floor slab 1. Step 6: Place the flatbed truck 9 on the two parallel tracks, and set the wheels 10 in the upward U-shaped slots of the channel steel cantilever beam 7. The flatbed truck 9 can move on the two parallel tracks by the traction rope 11 connected to the inner end of the flatbed truck 9, and transport the goods that are suspended outside the platform to the floor slab 1. Once the cantilever platform has completed its mission, simply remove the bolts connecting the horizontal plate 15 of the triangular fixing member 12 to the floor slab. The entire cantilever platform mechanism will then detach from the floor and can be disassembled into parts according to the steps described above. These parts can then be transported to the next floor for reassembly and reuse.
