Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete columns, in particular to a reinforced steel tube concrete column for heavy-duty factory buildings. Background Art

[0002] Reinforced concrete column is a column made of reinforced concrete. It is the most basic load-bearing component in various engineering structures such as houses, bridges, and hydraulic structures. It is often used as a support for floor slabs, bridge piers, foundation columns, towers, and compression rods for trusses.

[0003] In order to improve the compression and anti-destruction capabilities of concrete columns, steel structures are generally set on the surface of concrete columns, and wire mesh structures are added inside the concrete columns to improve the fracture resistance of slow-setting soil. When the reinforced concrete column is pouring concrete into the steel pipe, the downward gravity and weight of the concrete will cause the wire mesh to deform, affecting the fracture resistance of the concrete column where there is no wire mesh, making that part more fragile. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a reinforced steel tube concrete column for heavy-duty factory buildings, which has the effect of improving the deformation resistance of the steel wire mesh, thereby improving the overall quality of the concrete column.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A reinforced steel tube concrete column for heavy-duty factory buildings comprises a steel tube main body, a first connecting steel ring and a second connecting steel ring are arranged in the steel tube main body, a plurality of mounting rods are fixedly connected to the upper end of the second connecting steel ring, a wire braided mesh is arranged on the circumferential side of the plurality of mounting rods, a first connecting steel ring is arranged above the wire braided mesh, a plurality of groups of supporting mechanisms are arranged between the second connecting steel ring and the first connecting steel ring, a plurality of supporting seats are fixedly connected to the circumferential inner wall of the second connecting steel ring, each group of the supporting mechanisms comprises a reinforcing tube, two braided supporting layers and two arc-shaped supporting plates, the reinforcing tube is arranged at the upper end of the plurality of supporting seats, the two braided supporting layers are fixedly connected to the circumferential side of the reinforcing tube, and the two arc-shaped supporting plates are respectively fixedly connected to the other side of the two braided supporting layers; the plurality of reinforcing tubes are fixed by four connecting rods.

[0007] By adopting the above technical solution, the steel pipe body, the second connecting steel ring, the first connecting steel ring, the installation rod, the wire mesh and the supporting mechanism cooperate to support the wire mesh and the installation rod to prevent the steel pipe from being poured into the concrete.

[0009] By adopting the above technical solution, the slide rail and the T-shaped limit rod can limit the support mechanism to prevent the support mechanism from deviating during movement and preventing the movement from being not smooth enough.

[0010] In a preferred example, the utility model can be further configured as follows: a plurality of clamping nails are fixedly connected to the circumferential sides of the plurality of mounting rods, and the steel wire braided mesh is arranged between the plurality of clamping nails.

[0011] By adopting the above technical solution, the two clamping nails can clamp the steel wire mesh.

[0012] In a preferred example, the utility model can be further configured as follows: the upper and lower parts of the circumferential inner wall of the steel pipe body are both provided with first thread grooves, and the second connecting steel ring and the first connecting steel ring are respectively threadedly connected in the two first thread grooves.

[0013] By adopting the above technical solution, the first threaded groove can facilitate the connection between the second connecting steel ring and the first connecting steel ring and the steel pipe body, and can better prevent the bottom or top from being offset during casting.

[0014] In a preferred example, the utility model can be further configured as follows: a plurality of the support seats are each provided with a connecting groove at their upper ends, a plurality of the connecting grooves are each slidably connected with a connecting plate, and a connecting seat is fixedly connected between the plurality of connecting plates.

[0015] By adopting the above technical solution, the connecting groove and the connecting plate can facilitate the support of the support seat and the reinforcement pipe.

[0016] In a preferred example, the utility model can be further configured as follows: a second thread groove is opened on the upper part of the circumferential side of each of the plurality of mounting rods, a circular limit block is fixedly connected to the circumferential side of each of the plurality of mounting rods, and the plurality of circular limit blocks are fitted with the lower end of the first connecting steel ring, and a nut is threadedly connected in each of the plurality of second thread grooves.

[0017] By adopting the above technical solution, the mounting rod, the circular limiting block, the second threaded groove and the nut can facilitate the connection between the first connecting steel ring and the mounting rod.

The braided wire mesh 12 is fixed on the second connecting steel ring 18, and the braided wire mesh 12 is woven on the circumferential side of the mounting rod 13 along the mounting rod 13.
