Description

Technical Field

[0001] This invention relates to the field of support column technology, and in particular to a support column for the construction of chord beams. Background Technology

[0002] Tensioned beam structures are a hybrid structural system consisting of a rigid upper chord, flexible cables, and intermediate struts. Their structural composition is a novel self-balancing system, a large-span prestressed spatial structure, and a relatively successful innovation in the development of hybrid structural systems. Tensioned beam structures are simple, have clearly defined stress distribution, offer diverse structural forms, fully utilize the advantages of both rigid and flexible materials, and are easy to manufacture, transport, and construct, thus possessing promising application prospects.

[0003] During the construction of a tensioned beam, the rigid upper chord is first hoisted, followed by the installation of the flexible cables. Before the cables are under load, the rigid upper chord needs to be supported. Generally, a support frame needs to be erected below the rigid upper chord. Considering the design of the building, where the tensioned beams serve as the roof support structure, multiple sets are installed, and each tensioned beam requires support during construction. Therefore, the support frame needs to be movable. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a support column for chord beam construction, comprising a base, on the upper end of which several support units are vertically stacked. The support units are erected on the upper end of the base, and the upper end of the support units serves a supporting function.

[0005] The base includes a support plate, with several moving rollers positioned below the support plate and a support frame positioned below the support plate. Several hydraulic cylinders are fixedly connected to the support plate, and hydraulic rods extend from the lower ends of the hydraulic cylinders, with the lower ends of the hydraulic rods fixedly connected to the support frame. When the base needs to be fixed for support, the hydraulic cylinders actuate, the hydraulic rods extend, causing the support frame to contact the support surface, and the moving rollers to disengage from the support surface. Furthermore, depending on the control scenario, all hydraulic cylinders can be connected in parallel. This control method is simple, and each hydraulic cylinder can also be controlled independently, allowing adjustment of the support column's posture before and after force application. When the support column needs to be moved, the hydraulic cylinders actuate again, causing the telescopic rods to retract. At this time, the moving rollers contact the support surface, and then the base is pushed or pulled, realizing the overall movement of the support column.

[0006] Preferably, the support unit comprises a cuboid frame composed of rods, with two diagonal braces on each of the six faces of the frame, forming an "X" shape. A specified height is achieved by stacking a corresponding number of frames.

[0007] Preferably, a plurality of fixing bolts are inserted through the lower edge of the frame, and threaded holes are provided on the upper edge of the frame. When two support units are stacked, the fixing bolts are inserted through the lower end of the upper support unit and threaded into the threaded holes of the lower support unit.

[0008] Preferably, the frame has insertion holes at its lower four corners and insertion rods fixedly connected to its upper four corners. The insertion holes and rods serve a positioning function during the stacking of support units.

[0009] Preferably, a traction hole is fixedly connected to one side of the support plate, and a rubber pad is fixedly connected to the lower end of the support frame. The rubber pad mainly serves to prevent slippage and avoid uneven deformation of the rubber pad that could cause the support column to tilt. The rubber pad is thin enough.

[0010] Preferably, a plurality of support rods are fixedly connected to the lower end of the support plate, and the end shaft of the movable roller is rotatably fitted onto the lower part of the support rods. That is, the movable roller is rotatably connected to the support rods.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. A base is provided, and a support frame and a moving roller are provided on the base. When support is needed, the hydraulic cylinder works, and the support frame contacts the support surface. When the base needs to be moved, the hydraulic cylinder works again to lift the support frame, and the moving roller contacts the support surface. At this time, pulling and pushing the base can change the position of the base to meet the construction needs.

[0013] 2. It is equipped with a support unit, which is pre-positioned through the insertion holes and rods, and then fixed and connected by fixing bolts, which has the advantage of convenient assembly. Attached Figure Description

[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1 to 4 As shown, a support column for the construction of a chord beam includes a base 1, and several support units 2 are vertically stacked on the upper end of the base 1. The multiple support units 2 are stacked on the upper end of the base 1 according to the construction requirements.

[0023] The base 1 includes a support plate 12, which is a single plate. Several movable rollers 17 are arranged below the support plate 12. The movable rollers 17 are components used to move the base 1. A support frame 13 is arranged below the support plate 12. Several hydraulic cylinders 14 are fixedly connected to the support plate 12. The lower end of the hydraulic cylinders 14 extends to provide a hydraulic rod 18. The lower end of the hydraulic rod 18 is fixedly connected to the support frame 13. The arrangement of the movable rollers 17 and the support frame 13 realizes two functions of the base 1.

[0024] When fixed support is required, hydraulic cylinder 14 is activated, hydraulic rod 18 extends, and support frame 13 contacts support surface. At this time, support frame 13 serves as support for base 1. When base 1 needs to be moved, hydraulic cylinder 14 is activated again, hydraulic rod 18 retracts, support frame 13 retracts, and moving roller 17 contacts support surface. At this time, base 1 can be moved by pushing and pulling.

[0025] The support unit 2 includes a rectangular frame 23 composed of rods. The frame 23 is composed of twelve rods. Two diagonal rods 24 are provided on each of the six faces of the frame 23. The arrangement of the two diagonal rods 24 forming an "X" shape is to improve the structural strength of the frame 23.

[0026] Several fixing bolts 21 are inserted through the lower edge of the frame 23, and threaded holes 26 are provided on the upper edge of the frame 23. When the two support units 2 are stacked, the fixing bolts 21 are inserted through the lower end of the upper frame 23, and the fixing bolts 21 are threaded into the threaded holes 26 on the upper end of the lower frame 23.

[0027] The lower four corners of the frame 23 are provided with insertion holes 22, and the upper four corners of the frame 23 are fixedly connected with insertion rods 25. When the two support units 2 are stacked, they are connected by the insertion rods 25 and the insertion holes 22, and then fixed by fixing bolts 21.

[0028] A traction hole 11 is fixedly connected to one side of the support plate 12. A traction rope is connected to the traction hole 11 for traction of the base 1. A rubber pad 15 is fixedly connected to the lower end of the support frame 13. The rubber pad 15 plays a role in anti-slip and buffering, and the rubber pad 15 is relatively thin.

[0029] Several support rods 16 are fixedly connected to the lower end of the support plate 12, and the end shaft of the movable roller 17 is rotatably fitted to the lower part of the support rods 16. That is, the movable roller 17 is rotated and set by the support rods 16.
