Description

Technical Field

[0001] This invention relates to the field of elevator shaft protection technology, and in particular to a protective structure for elevator shafts in building construction and its construction method. Background Technology

[0002] With the rapid urbanization in my country and the accelerated construction of high-rise buildings, elevator shaft protection is of paramount importance for construction safety. The typical protective measure in elevator shafts is a horizontal netting system with large mesh. In the past, elevator shaft protection often involved using steel bars to press the netting against the wall or simply pulling it with wire. This method required workers to remain inside the elevator shaft for extended periods until the netting was fully installed, posing significant safety risks. Furthermore, the installation process was time-consuming, and dismantling required workers to enter the shaft to cut the steel bars and wires, wasting materials. Additionally, the horizontal netting was prone to instability due to the high-risk conditions, rendering this type of protection ineffective.

[0003] In view of the current problems of complex installation, troublesome disassembly, and the fact that most elevator shaft protection is for single use and wastes materials, we propose a building construction elevator shaft protection structure and its construction method. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a building construction elevator shaft protection structure and its construction method that are easy to recycle, thereby improving turnover efficiency and structural safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention includes: a protective door for engaging with the elevator shaft entrance, a support base connected to the protective door and for engaging with the elevator shaft, the support base including a fixed frame connected to the protective door, a rotating frame rotatably connected to the fixed frame on the side away from the protective door, and a locking component for locking the rotating frame in a state where it is rotated to be flush with the fixed frame, the outer periphery of the rotating frame being provided with a snap-fit ​​member for engaging with the inner wall of the elevator shaft, and the top of both the fixed frame and the rotating frame having a lifting lug for hoisting with a hoisting rope.

[0006] A further improvement of the protective structure for elevator shafts in building construction of the present invention is that the protective door is provided with a connecting chamber, the fixed frame is provided with a sliding chamber communicating with the connecting chamber, and the locking assembly includes a first rotating rod vertically disposed in the connecting chamber, a second rotating rod disposed perpendicular to the protective door, a third rotating rod disposed horizontally in the connecting chamber, a fourth rotating rod disposed perpendicular to the protective door in the sliding chamber, and a sliding plate slidably disposed in the sliding chamber. The first end of the second rotating rod extends out of the protective door and forms a rotating handle, the second end of the second rotating rod is rotatably connected to the first rotating rod through a first meshing gear set, the top end of the first rotating rod is rotatably connected to the third rotating rod through a second meshing gear set, the third rotating rod is rotatably connected to the fourth rotating rod through a third meshing gear set, the fourth rotating rod has a threaded section formed on it, the bottom of the sliding plate is fixed with a threaded sleeve for screwing into the threaded section, an insertion rod is fixed on the sliding plate along the direction of the fourth rotating rod, and the rotating frame is provided with an insertion hole for inserting the insertion rod.

[0007] A further improvement of the protective structure for elevator shafts in building construction of the present invention is that a baffle for preventing the sliding plate from sliding out of the threaded section is connected to the fourth rotating rod.

[0008] A further improvement of the protective structure for elevator shafts in building construction of the present invention is that a reinforcing diagonal brace is also connected between the protective door and the fixed frame.

[0009] A further improvement of the protective structure for elevator shafts in building construction of the present invention is that a limiting block for engaging with the elevator opening is formed at the bottom of the protective door, and a locking block for engaging with the upper floor of the elevator shaft opening is formed at the top of the protective door.

[0010] A further improvement of the protective structure for elevator shafts in building construction of the present invention is that the second meshing gear set includes a driving bevel gear and a driven bevel gear meshing together, the driving bevel gear being coaxially connected to the end of the first rotating rod, and the driven bevel gear being coaxially connected to the third rotating rod.

[0011] This invention also provides a construction method for a protective structure for an elevator shaft in building construction, comprising the following steps:

[0012] Provide the above-mentioned protective structure for building construction elevator shafts;

[0013] Lifting ropes are attached to the lifting lugs of the fixed frame and the rotating frame respectively, and the protective structure is hoisted to the height of the floor to be constructed using the lifting ropes on the fixed frame.

[0014] Connect the protective door clip to the elevator shaft entrance, pull the suspension rope on the rotating frame to rotate the rotating frame clockwise until the rotating frame is flush with the fixed frame, stop pulling, use the clip to clip the rotating frame to the inner wall of the elevator shaft, and use the locking component to lock the rotating frame.

[0015] A further improvement to the construction method of the elevator shaft protective structure of the present invention is that, when constructing the next floor to be constructed, the snap-fit ​​parts are loosened and the locking components are used to release the constraint on the rotating frame. At the same time, the suspension rope on the rotating frame is released, and the rotating frame rotates counterclockwise due to its own gravity, pushing the protective door out of the elevator shaft doorway, so that the entire protective structure is suspended in the elevator shaft. The suspension rope on the fixed frame is then pulled to hoist the protective structure to the height of the next floor to be constructed.

[0016] A further improvement of the construction method of the protective structure for building construction elevator shaft of the present invention is that a limiting block for engaging with the elevator entrance is formed at the bottom of the protective door, and a locking block for engaging with the upper floor of the elevator entrance is formed at the top of the protective door.

[0017] When attaching the protective door to the elevator shaft entrance, attach the bottom limiting block of the protective door to the elevator shaft entrance, and attach the top locking block of the protective door to the upper floor inside the elevator shaft.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] 1. By dividing the support base into a fixed frame and a rotating frame rotatably connected thereto, the overall support and turnover of the device are facilitated.

[0020] 2. By setting the locking component, construction personnel can more easily restrain the rotating frame at the protective door, which is more efficient. Attached Figure Description
