Description

Technical Field

[0001] This invention relates to a construction operation platform and construction operation method for a fully enclosed ventilation shaft structure in ultra-high-rise buildings, belonging to the field of building construction technology. Background Technology

[0002] When constructing super high-rise buildings, it is necessary to build a fully enclosed ventilation shaft structure for unified ventilation in the later stage. In order for construction workers to have a standing base to carry out decoration work in the fully enclosed ventilation shaft, a construction operation platform needs to be built in the ventilation shaft.

[0003] Existing construction operation platforms for ventilation shafts, such as the one disclosed in Chinese Patent Publication No. CN217602032U, use a longitudinal horizontal bar that is vertically and intersectingly fixed to a transverse bar at the shaft opening to limit the operation within the ventilation shaft. Although this can create a construction operation platform within the ventilation shaft, the bar body needs to be disassembled and reassembled when the floor is lifted, which reduces construction efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a construction operation platform and construction operation method for a super high-rise fully enclosed ventilation shaft structure.

[0005] The present invention is achieved through the following technical solutions.

[0006] This invention provides a construction operation method for a super high-rise fully enclosed ventilation shaft structure, comprising:

[0007] The construction operation process of lifting the construction operation platform in the ventilation shaft without disassembling it.

[0008] The construction operation process is as follows: When the floor is being lifted, the top support angle is adjusted by adjusting the nut on the screw rod so that the top support angle is close to the square steel frame and no longer presses against the inner wall of the ventilation shaft. The universal ball is rotated out on the screw rod, and the rotatable ball can roll into contact with the inner wall of the ventilation shaft. The tower crane lifts the lifting ring, and the lifting ring pulls the steel plate. The steel plate pulls the square steel frame to roll and lift it to the installation position on the next floor. After the through-wall bolts are installed, the square steel frame is installed. The universal ball is screwed into the screw rod and no longer contacts the inner wall of the ventilation shaft. The top support angle is adjusted to press against the inner wall of the ventilation shaft and limit the movement of the square steel frame.

[0009] A construction operation platform for a super high-rise fully enclosed ventilation shaft structure includes:

[0010] Two sets of parallel through-wall bolts pass through the pre-drilled holes in the ventilation shaft;

[0011] A square steel frame is installed on the through-wall bolts.

[0012] The top support components are symmetrically distributed and fixed on both sides of the square steel frame. After the square steel frame is installed on the through-wall bolts, the top support components are limited against the inner wall of the ventilation shaft. The top support components are adjusted so that when they are lifted, the contact limit with the inner wall of the ventilation shaft changes to a rolling contact.

[0013] The top support assembly includes a threaded rod that is fixedly connected to the square steel frame;

[0014] A top support angle with a through hole is provided on the screw rod, and the screw rods on both sides of the top support angle are screwed with nuts for clamping and adjustment;

[0015] The universal ball screwed into the threaded hole inside the screw can roll into contact with the inner wall of the ventilation shaft. When the universal ball is screwed into the screw, the rolling ball of the universal ball does not roll into contact with the inner wall of the ventilation shaft. The top support angle is adjusted by adjusting the position of the nut on the screw so that the top support angle surface contacts and abuts against the inner wall of the ventilation shaft and limits the steel frame.

[0016] The omnidirectional ball is fixed with a plate hexahedron on its outside.

[0017] The square steel frame has steel plates for construction workers to step on.

[0018] The steel plates consist of four pieces, with the edge of the steel plate closest to the top support assembly rotatable within the square steel frame, and the steel plates are rotatably installed relative to each other.

[0019] The square steel frame has a crossbar in the middle to support the steel plate. The crossbar has a hole inside to hold an elastic rubber column. The top edge of the hole in the crossbar has an opening so that the elastic rubber column protrudes when it is squeezed. The opening of the hole in the crossbar is connected by a threaded pair to a compression bolt for squeezing the elastic rubber column. The compression bolt is screwed into the hole in the crossbar and pushes against the elastic rubber column, causing elastic deformation and forming a protrusion.

[0020] The steel plate is fixed with lifting rings that are connected to the tower crane's lifting ropes.

[0021] The beneficial effects of this invention are: it enables the construction of a construction operation platform in the ventilation shaft that can be lifted without disassembly, solving the problem of having to disassemble and reassemble the poles when lifting floors, thus improving construction efficiency.

Detailed Implementation

[0028] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0029] like Figures 1 to 5 As shown.

[0030] This application discloses a construction operation platform for a fully enclosed ventilation shaft structure in ultra-high-rise buildings, comprising:

[0031] Through-wall bolts 2 are inserted through the reserved holes in the ventilation shaft 1. The through-wall bolts 2 are two sets distributed in parallel. The ventilation shaft 1 and the floor slab 21 of the super high-rise building are fixed together by being cast with reinforced concrete. The ventilation shaft 1 is connected to the upper and lower four walls to form a fully enclosed structure.

[0032] A square steel frame 3 is installed on the through-wall bolt 2, and a steel plate 4 is laid on the square steel frame 3 for construction workers to step on; there are four steel plates 4, and the side of the steel plate 4 facing the top support component 6 can be rotated on the square steel frame 3 by a hinge, and the steel plates 4 can be rotatably installed with each other by hinges (hinges not shown in the figure).

[0033] The square steel frame 3 has a crossbar 31 in the middle to support the steel plate 4. The crossbar 31 has a closed hole inside to hold an elastic rubber column 32. The top edge of the closed hole in the crossbar 31 has an opening; when the elastic rubber column 32 is compressed, a protrusion 33 protrudes. A compression bolt 34, threaded through the opening of the closed hole in the crossbar 31, is used to compress the elastic rubber column 32. The compression bolt 34 screws into the closed hole of the crossbar 31, causing the elastic rubber column 32 to deform elastically, thus creating the protrusion 33. This allows the steel plate 4 and the square steel frame 3 to make flexible contact through the elastic protrusion 33, absorbing shock. When workers or objects are placed on the steel plate 4, the contact between the steel plate 4 and the square steel frame 3 is not rigid, preventing the amplification of noise generated within the ventilation shaft 1, thus providing a better construction environment. Simultaneously, it ensures that the contact between the steel plate 4 and the square steel frame 3 is not rigid, improving service life. When the compression bolt 34 is unscrewed, the elastic rubber column 32 deforms elastically and retracts into the closed hole of the crossbar 31.

[0034] A lifting ring 5 is welded and fixed on the steel plate 4. The lifting ring 5 facilitates connection with the lifting rope of the tower crane to serve as a lifting force-bearing component.

[0035] A top support assembly 6 is installed on the outside of the square steel frame 3. After the square steel frame 3 is installed on the through-wall bolts 2, the top support assembly 6 is placed against the inner wall of the ventilation shaft 1 for limiting. The load generated by the construction workers stepping on the steel plate 4 above the square steel frame 3 is transferred to the structure of the ventilation shaft 1 through the through-wall bolts 2, and then to the floor slab 21 of the super high-rise building. There are four top support assemblies 6, which are symmetrically distributed in pairs on both sides of the square steel frame 3.

[0036] The top support assembly 6 includes a screw rod 61 welded and fixedly connected to the square steel frame 3; a top support angle 62 with a through hole fitted on the screw rod 61, and nuts 64 screwed into the screw rod 61 on both sides of the top support angle 62 for clamping and adjustment; a universal ball 63 screwed into the threaded hole inside the screw rod 61 for rolling contact with the inner wall of the ventilation shaft 1, and a plate hexahedron 65 welded and fixed to the outside of the universal ball 63 for easy wrench engagement; when the square steel frame 3 is placed on the through bolt 2, the universal ball 63 is screwed into the screw rod 61, and the rolling ball of the universal ball 63 does not roll contact with the inner wall of the ventilation shaft 1. The top support angle 62 is adjusted by adjusting the position of the nuts 64 on the screw rod 61 so that the surface of the top support angle 62 contacts and abuts against the inner wall of the ventilation shaft 1 to limit the square steel frame 3.

[0037] This application discloses a construction method for a fully enclosed ventilation shaft structure in ultra-high-rise buildings, comprising:

[0038] During floor lifting, the top support angle 62 is adjusted by the nut 64 on the screw rod 61, causing the top support angle 62 to move towards the square steel frame 3. The top support angle 62 no longer presses against the inner wall of the ventilation shaft 1. The universal ball 63 is unscrewed on the screw rod 61, and the rotatable ball of the universal ball 63 can roll and contact the inner wall of the ventilation shaft 1. The tower crane lifts the lifting ring 5, which pulls the steel plate 4. The steel plate 4 pulls the square steel frame 3 to roll and lift it to the installation position of the next floor. After the through-wall bolt 2 is installed, the square steel frame 3 is installed. The universal ball 63 is screwed into the screw rod 61 and no longer contacts the inner wall of the ventilation shaft 1. The top support angle 62 is adjusted to contact the inner wall of the ventilation shaft 1 and limit the square steel frame 3. This creates a construction operation platform in the ventilation shaft 1 that can be lifted without disassembly, solving the problem of disassembling and reassembling the pole body during floor lifting and improving construction efficiency.
