Description

Technical Field

[0001] The present application relates to a protective shed structure, and in particular to a liftable cantilevered protective shed structure, belonging to the technical field of construction safety devices. Background Art

[0002] Operations at the edge of high-rise buildings are very dangerous, and protective devices need to be installed at the edge for convenient construction. The prior art generally adopts a cantilevered structure, usually requiring large holes to be reserved at the shear wall or column parts for installing cantilevered I-beams. On the one hand, the reserved holes are relatively large, which is not convenient for the subsequent exterior wall decoration. On the other hand, the traditional cantilevered steel beams are very long and cannot be lifted. During layer-by-layer construction, the cantilevered steel beams and the protective shed need to be disassembled into separate components and then reassembled on the new floor. The disassembly and installation efficiency is relatively low, and the installation difficulty is relatively large, and the construction intensity of workers is high. Summary of the Invention

[0003] The purpose of the present application is to provide a liftable cantilevered protective shed structure. The cantilevered protective shed structure can be integrally lifted and installed on any floor, with high disassembly and installation efficiency and reduced labor intensity of workers.

[0004] To achieve the above purpose, the technical solution of the present application is: A liftable cantilevered protective shed structure includes multiple floors. It is characterized in that: A plurality of vertically arranged and parallel vertical support slide rails are fixed between the multiple floors. A sliding fixed seat is slidably installed on the vertical support slide rails. A horizontally arranged cantilever main beam is fixed on the sliding fixed seat. The outer end of the cantilever main beam extends outwards from the floor. The sliding fixed seat is fixed to the rear end or the middle position of the cantilever main beam. A floor fixed steel beam is fixed on the floor through floor embedded parts. The floor fixed steel beam is connected and fixed to the cantilever main beam. A plurality of mutually parallel cantilever cross beams are arranged between the multiple cantilever main beams. A steel mesh is laid on the upper surfaces of the cantilever main beam and the cantilever cross beam. An inclined pull steel wire rope is connected between the outer end of the cantilever main beam and the upper floor of the cantilever main beam.

[0005] Further, protective railings are installed between the outer ends of the multiple cantilever main beams and at the ends of the multiple cantilever cross beams, and a protective net is installed on the protective railings.

[0006] Further, a plurality of floor edge embedded parts are installed at the edge of the floor, and connection ears convenient for connecting the inclined pull steel wire rope are installed on the floor edge embedded parts.

[0007] Further, a hook convenient for connecting during hoisting and lifting is installed on the sliding fixed seat.

[0008] Further, the outer end of the floor fixed steel beam and the rear end of the cantilever main beam overlap with each other and are connected and fixed through a U-shaped fixing piece and a bolt.

[0009] Furthermore, a threaded through hole is provided on the sliding fixing seat, and a locking screw is screwed on the threaded through hole. The locking screw contacts the vertical support rail and locks the sliding fixing seat on the vertical support rail.

[0010] The beneficial effects of this application are:

[0011] 1. This application fixes the cantilevered cantilever frame main beam to the edge of the floor slab through the floor slab fixed steel beam, which greatly shortens the length and changes the traditional cantilevered steel beam structure with a long length. Under the premise of ensuring reliable fixation, it provides favorable conditions for the overall lifting.

[0012] 2. The structure of this application is reasonable. After the cantilever frame main beam and the floor fixing steel beam are loosened, the cantilever structure and the protective shed can be raised and lowered as a whole. They can be conveniently fixed on any floor according to installation needs. There is no need to repeatedly disassemble and assemble the cantilever structure and the protective shed, and the installation and use efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A threaded through hole is provided on the sliding fixed seat 3, and a locking screw 16 is screwed on the threaded through hole, and the locking screw 16 abuts against the vertical support slide rail 2 to lock the sliding fixed seat 3 on the vertical support slide rail 2.

[0023] In the present application, the cantilevered protective shed outside the floor adopts an integral lifting and sliding structure, which can be conveniently fixed on any floor according to the installation needs, can be lifted, and does not require repeated disassembly and assembly of the cantilever structure and the protective shed, with high use efficiency. At the same time, the adopted floor-fixed steel beam can be conveniently connected and fixed to and separated from the main cantilever beam of the shed, and the length is greatly shortened, providing favorable conditions for integral lifting on the premise of ensuring reliable fixation. The specific structure of the present application is described as follows:

[0024] A plurality of vertically arranged vertical support slide rails 2 are fixed between the multi-layer floor slabs 1 of the building. The plurality of vertical support slide rails 2 are parallel to each other and arranged at equal intervals. A sliding fixing seat 3 is slidably mounted on the vertical support slide rail 2. A horizontally arranged main cantilever beam 7 of the cantilever scaffold is fixed on the sliding fixing seat 3. The main cantilever beam 7 of the cantilever scaffold is perpendicular to the edge of the floor slab 1. The outer end of the main cantilever beam 7 of the cantilever scaffold extends out of the floor slab 1. The sliding fixing seat 3 is fixed to the rear end or the middle position of the main cantilever beam 7 of the cantilever scaffold. A locking structure is provided between the sliding fixing seat 3 and the vertical support slide rail 2. A threaded through hole is provided on the sliding fixing seat 3, and a locking screw 16 is screwed on the threaded through hole. The sliding fixing seat 3 is locked on the vertical support slide rail 2 by the locking screw 16 abutting against the vertical support slide rail 2.

[0025] In order to fix the main cantilever beam 7 of the cantilever scaffold outside the floor slab 1, a floor fixing steel beam 4 is fixed on the floor slab 1 through a floor embedded part 5. The floor embedded part 5 and the floor fixing steel beam 4 can be fixed by welding or using bolts, so as to fix the floor fixing steel beam 4 on the floor slab 1. The floor fixing steel beam 4 is connected and fixed to the main cantilever beam 7 of the cantilever scaffold. The outer end of the floor fixing steel beam 4 and the rear end of the main cantilever beam 7 of the cantilever scaffold overlap each other and are connected and fixed through a U-shaped fixing part 6 and a bolt. The main cantilever beam 7 of the cantilever scaffold is cantilever-fixed through the floor fixing steel beam 4, which changes the traditional structure of directly extending a very long fixing steel beam outside the floor slab, and facilitates disassembly and assembly.

[0026] A plurality of mutually parallel cantilever scaffold cross beams 8 are arranged between the plurality of main cantilever beams 7 of the cantilever scaffold. The plurality of cantilever scaffold cross beams 8 are arranged at equal intervals and are connected and fixed to the main cantilever beams 7 of the cantilever scaffold. In order to further ensure the load-bearing capacity of the structure constructed by the plurality of main cantilever beams 7 of the cantilever scaffold and the plurality of cantilever scaffold cross beams 8 and make the structure safer and more reliable, a stay cable 13 is connected between the outer end of the main cantilever beam 7 of the cantilever scaffold and the upper floor slab of the floor where the main cantilever beam 7 of the cantilever scaffold is located. By hanging the main cantilever beam 7 of the cantilever scaffold through the stay cable 13, the load-bearing capacity of the structure is improved. In order to facilitate the installation of the stay cable 13, a floor edge embedded part 12 is installed at the edge of each floor slab 1, and a connecting ear 14 convenient for connecting the stay cable 13 is installed on the floor edge embedded part 12.

[0027] During the overall disassembly, assembly and lifting process of the structure constructed by the plurality of main cantilever beams 7 of the cantilever scaffold and the plurality of cantilever scaffold cross beams 8, only the main cantilever beam 7 of the cantilever scaffold needs to be loosened and separated from the floor fixing steel beam 4, the locking screw 16 is loosened, the sliding fixing seat 3 is loosened from the vertical support slide rail 2, and then the whole is hoisted. In order to facilitate the hanging and taking of the lifting hook when the sliding fixing seat 3 is lifted, a hook 15 convenient for connecting during hoisting and lifting is installed on the sliding fixing seat 3.

[0028] The upper surfaces of the main beams 7 of the cantilever scaffold and the cross beams 8 of the cantilever scaffold are paved with steel mesh sheets 9 for construction workers to step on. A circle of guardrails 10 is installed between the outer ends of multiple main beams 7 of the cantilever scaffold and between the ends of multiple cross beams 8 of the cantilever scaffold. A protective net 11 is installed on the guardrails 10 to prevent construction workers and objects from falling.

It cannot be considered that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, the present application will have various simple substitutions, improvements and changes. All the simple substitutions, improvements and changes made should be regarded as belonging to the protection scope of the present application.
