Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel diagonal bracing device for large cantilever components. Background Technology

[0002] With the continuous improvement of living environment, people are not only satisfied with the safety, applicability, durability and economy of buildings, but also have higher requirements for the aesthetics of buildings. In particular, the visual impact of building facades is increasing, resulting in a large number of large-span super cantilever reinforced concrete structural slabs to achieve a visual feast. In order to ensure the safety of large cantilever slab structures, it is necessary to design corresponding auxiliary measures to ensure that the mechanical performance of large cantilever components meets the requirements of the specifications.

[0003] To meet the mechanical performance requirements of conventional large cantilever components, the following measures are often taken:

[0004] 1. Increase slab thickness: Appropriately increasing the thickness of the cantilever slab can improve its load-bearing capacity and bending resistance.

[0005] 2. Prestressing technology: By applying prestress to the cantilever slab, pre-compressive stress can be generated in the slab to offset part of the tensile stress generated by the load, thereby improving the crack resistance and load-bearing capacity of the slab.

[0006] 3. Use of ultra-high performance concrete: Utilize the excellent mechanical properties of ultra-high performance concrete to achieve increased slab span and thinner slab thickness.

[0007] 4. Add auxiliary rods: Improve the mechanical performance of the large cantilever slab by adding upper tie rods or struts.

[0008] Due to the varying floor heights, the steel braces are quite long, with the longest used in the project reaching approximately 10 meters. This results in significant weight and inconvenience in handling. Furthermore, the primary function of the steel braces is to provide an upward force to the cantilevered component, preventing it from deforming downwards due to gravity. If an upward pre-pushing force is not applied to the cantilevered component after installation, it will inevitably deform downwards because it has not yet formed reliable contact with the naturally installed steel braces. Only when the downward deformation is met by the steel braces does the steel braces truly generate an upward pushing force. In this case, the cantilevered component has already deformed downwards, causing damage to the component itself. Therefore, this solution designs a steel bracing device for large cantilevered components. Utility Model Content

[0009] The purpose of this utility model is to provide a steel diagonal bracing device for large cantilever components, which solves the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a steel diagonal bracing device for a large cantilever component, comprising a sleeve, both ends of the inner wall of the sleeve being threaded, threaded pipes being threaded to both ends of the sleeve, an A-bracing pipe being fixedly connected to one end of the threaded pipe, an A-flange being fixedly connected to one end of the A-bracing pipe, an insertion hole being provided on the surface of the A-flange, a bolt being inserted into the insertion hole, and a B-flange being fixedly connected to the A-flange by bolts.

[0011] Preferably, a B-support pipe is fixedly connected to the surface of the B flange, and a connecting block is fixedly connected to the top end of the B-support pipe.

[0012] Preferably, a rotating seat is fixedly connected to the upper surface of the connecting block, a pin is inserted into one side of the rotating seat, and the rotating block is rotatably connected to the rotating seat through the pin.

[0013] Preferably, one end of the rotating block is fixedly connected to an embedded part, the embedded part including two connecting plates, and a connecting rod is fixedly connected between the two connecting plates.

[0014] Preferably, one of the connecting plates is fixed to the rotating block, the surface of the sleeve is provided with a control groove, the inner wall of the control groove is fixedly connected with a connecting piece, and one side of the connecting piece is also fixedly connected with a sealing piece by a screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This equipment is assembled from various components during use, which greatly reduces the size of individual components. It can be transported to the construction site in sections and assembled there, making construction simpler. At the same time, during equipment installation, the threaded pipes installed at the top and bottom can be adjusted. By tightening, the diagonal brace can be extended or retracted. After installation, the sleeve can be rotated to extend or retract at both ends, achieving pre-jacking of the diagonal brace. This avoids insufficient pre-jacking force, which could cause the cantilevered component to deform downwards and become damaged. The use of this equipment improves the safety of the diagonal brace of large cantilevered components. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a steel diagonal bracing device for a large cantilever component, including a sleeve 1. Both ends of the inner wall of the sleeve 1 are threaded. Threaded pipes 2 are threaded to both ends of the sleeve 1. A support pipe 3 is fixedly connected to one end of the threaded pipe 2. A flange 4 is fixedly connected to one end of the A support pipe 3. Insertion holes are opened on the surface of the A flange 4. Bolts 5 are inserted into the insertion holes. A flange 6 is fixedly connected to the A flange 4 by bolts 5.

[0027] The upper and lower threaded pipes 2 are adjusted by screws to adapt to the support requirements, and the equipment provides sufficient pre-jacking force to ensure the stability of the diagonal brace.

[0028] The surface of flange B6 is fixedly connected to support tube B7, and the top end of support tube B7 is fixedly connected to connecting block 8.

[0029] By connecting sleeve 1 to the flanges of the two support pipe sections, the size of each component is greatly reduced, making it easier to transport in sections and simplifying construction.

[0030] A rotating seat 9 is fixedly connected to the upper surface of the connecting block 8. A pin 10 is inserted into one side of the rotating seat 9, and the rotating seat 9 is rotatably connected to the rotating block 11 through the pin 10.
