Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for building construction, in particular to a formwork support structure and a support system. Background Art

[0002] With the continuous development of domestic formwork support construction technology, a large number of supports are used for supporting construction in logistics warehouses, production plants, high-speed rail stations, urban subway depots, bus stations, etc.

[0003] Logistics warehouses and production plants have complex structures, with many waist beams, frame beams and structural interlayers, especially in the case of multi-layer waist beams. In response to the above complex construction conditions, the traditional construction method is generally to place two joists on the connection plate of the vertical pole in the built bracket. The two joists are located on both sides of the vertical pole and are fixed and clamped with bolts. However, after the bracket is built, the connection plate of the vertical pole is fixed and the height cannot be adjusted, resulting in the height of the joists being unable to be adjusted. When the height of the joists is lower than the height of the formwork, a small bracket needs to be set up on the two joists to support the formwork. Not only is the construction complex and inefficient, but it will also increase the input of materials, resulting in increased costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a formwork support structure and a formwork support system which can simplify construction operations, improve construction efficiency, reduce material input, lower costs, be easy to implement and apply, and have simple and flexible assembly and disassembly.

[0006] A formwork support structure includes two vertical support rods and a support beam connected between the two vertical support rods, the vertical support rods include two vertical rods and an intermediate rod connected between the two vertical rods, the two ends of the intermediate rod are respectively inserted into the inner cavities of the two vertical rods in a manner that can adjust the insertion depth, a supporting mechanism and two limit members that can adjust the installation position up and down are installed on the intermediate rod, the two limit members respectively correspond to the ends of the two vertical rods, and the support beam is supported and placed on the supporting mechanism of the intermediate rod between the two vertical support rods.

[0007] As a further improvement of the above technical solution:

[0008] The supporting mechanism includes a supporting sleeve and an adjusting nut. The supporting sleeve is sleeved on the outside of the intermediate rod and can adjust its position along the intermediate rod. The adjusting nut is threadably matched with the intermediate rod and can adjust its position height along the intermediate rod by screwing. The supporting sleeve is supported at the upper end of the adjusting nut, and the supporting sleeve is provided with a supporting portion for supporting the supporting beam.

[0014] The supporting beam comprises two beam bodies supported on a supporting mechanism, the middle rod is located between the two beam bodies, and the two beam bodies are connected by a detachable fastener and clamp the middle rod.

There is no need to set up a small support on the support beam, which can not only simplify the construction operation and improve the construction efficiency, but also reduce the material input and reduce the cost. At the same time, it is only necessary to configure the intermediate rod, the supporting mechanism and the limiting member on the basis of the existing formwork support, which is easy to implement and apply, and has a low application cost. The intermediate rod is inserted into the inner cavity of the vertical rod and then cooperates with the limiting member to abut against the end of the vertical rod for installation and positioning. It can not only ensure the stability and reliability of the support of the vertical support rod, but also is easy to install and disassemble, and is convenient for flexible setting of the position of the intermediate rod.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1:

[0027] like Figures 1 to 4 As shown, the formwork support structure of this embodiment includes two vertical support rods 1 and a support beam 2 connected between the two vertical support rods 1. The vertical support rod 1 includes two vertical rods 11 and an intermediate rod 12 connected between the two vertical rods 11. The two ends of the intermediate rod 12 are respectively inserted into the inner cavities of the two vertical rods 11 in a manner that the insertion depth can be adjusted. The upper end of the intermediate rod 12 is inserted into the lower inner cavity of the upper vertical rod 11 in a manner that the insertion depth can be adjusted. The lower end of the intermediate rod 12 is inserted into the upper inner cavity of the lower vertical rod 11 in a manner that the insertion depth can be adjusted. A supporting mechanism and two limit members 3 that can adjust the installation position up and down are installed on the intermediate rod 12. The two limit members 3 respectively correspond to the ends of the two vertical rods 11, and the support beam 2 is supported and placed on the supporting mechanism of the intermediate rod 12 of the two vertical support rods 1. The formwork support structure connects the middle rod 12 between the two vertical rods 11 of the vertical support rod 1, and the middle rod 12 is equipped with a supporting mechanism that can adjust the installation position up and down. The support beam 2 is supported and placed on the supporting mechanism. The height of the supporting mechanism can be adjusted as needed, that is, the height of the support beam 2 can be adjusted to meet the needs of template support of different heights. There is no need to set up a small bracket on the support beam 2, which can not only simplify the construction operation and improve the construction efficiency, but also reduce the material input and reduce the cost. At the same time, it is only necessary to configure the middle rod 12, the supporting mechanism and the limiter 3 on the basis of the existing formwork support, which is easy to implement and apply, and has a low application cost. The middle rod 12 is inserted into the inner cavity of the vertical rod 11 and then cooperates with the limiter 3 to abut against the end of the vertical rod 11 for installation and positioning. It can not only ensure the support stability and reliability of the vertical support rod 1, but also is easy to install and disassemble, and is convenient for flexible setting of the position of the middle rod 12.

The supporting sleeve 4, the adjusting nut 5 and the supporting nut in this embodiment are precision steel castings.

[0034] In this embodiment, the vertical pole 11 is a rod with a connecting wheel used to connect the central support rod 1 of the disc-type scaffolding. The rod is a conventional component connected to form a disc-type scaffolding in the prior art. Therefore, it is only necessary to configure the middle pole 12, the supporting mechanism and the limit member 3 on the basis of the existing formwork support.

[0035] In this embodiment, the joist 2 includes two beam bodies 21 supported on a supporting mechanism, the middle rod 12 is located between the two beam bodies 21, and the two beam bodies 21 are connected by detachable fasteners and clamp the middle rod 12, and the connection is stable and reliable with high supporting capacity. The detachable fasteners are preferably bolts. In other embodiments, the joist 2 can also be a single beam or a beam of other structural forms.
