Description

Technical Field:

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a verticality stabilizing device for a steel column with a small cross-section. Background Art:

[0002] The steel-concrete hybrid structure system is a new type of structure system that has developed rapidly in China in recent years. After the steel column is installed in place, its planar position and verticality should be corrected in a timely manner. However, the structure of the tube-in-tube in the hybrid structure system results in a small cross-section of the steel column in the core tube, with poor anti-interference ability, and it is easily disturbed by subsequent processes such as steel bar binding and concrete pouring. If no reinforcement measures are taken, the verticality of the steel column with a small cross-section cannot be guaranteed, and the subsequent hoisting and correction of the steel beam and the installation of the outer frame steel beam will all be affected to varying degrees. The existing treatment method is to repeatedly measure and correct during subsequent processes such as steel bar binding, aluminum formwork closing, and concrete pouring, which have a large impact on the verticality of the steel column with a small cross-section, after the installation and correction of the steel column. Before concrete pouring, 8mm steel bars are welded at the bottom of the steel column to ensure that the verticality of the steel column with a small cross-section is not greatly disturbed by the concrete. However, subsequent measurement and correction are still required, and the effect is not very ideal. The consumption of steel bars is large, and the workload of repeated measurement and correction is large. Content of the Utility Model:

[0003] The purpose of the utility model is to provide a verticality stabilizing device for a steel column with a small cross-section, so that the vertical axis of the steel column with a small cross-section is not disturbed by subsequent processes, and the problems in the background art are solved.

By arranging the support rod between the two steel columns, the offset of the steel column caused by being disturbed in subsequent processes is avoided, and the workload and material consumption of verticality correction are reduced.

[0006] The width of the connecting plate is greater than the width of the wing plate; two rows of through holes are arranged on each connecting plate, and the distance between the left and right through holes is equal to the width of the wing plate; the lead screw passes through the through holes and is fixed on the connecting plate by nuts.

[0023] Embodiment 1

[0024] A verticality stabilizing device for a small-section steel skeleton column, as Figure 1 shown, it includes two columns of H-shaped steel skeleton columns 10. There is an original steel beam 40 connected between each column of steel skeleton columns 10. The positions of the two columns of steel skeleton columns 10 correspond to each other. The flanges 11 of the two columns of steel skeleton columns 10 are arranged opposite to each other, and a support rod 20 is arranged between the corresponding two steel skeleton columns 10.

[0025] As Figure 2 , Figure 3As shown in the figure, several nails 13 are vertically fixed on the wing plates 11. On the outer sides of the two wing plates 11 of the steel column 10, a connecting plate 30 is arranged respectively. The bottom of the connecting plate 30 is stuck on the nails 13, and the two connecting plates 30 are fixed together by a screw rod 31; on the connecting plate 30 on the side of the steel column 10 close to the corresponding steel column 10, a fixing plate 32 is fixed and a groove 34 is formed. As Figure 4 shown, the width of the connecting plate 30 is greater than the width of the wing plate 11; two rows of through holes are arranged on each connecting plate 30 from left to right, and the distance between the left and right through holes is equal to the width of the wing plate 11; the screw rod 31 passes through the through holes and is fixed on the connecting plate 30 by a nut 33; the groove 34 is arranged between the through holes and the fixing plate 32.

[0026] The support rod 20 includes a central rod 21. At both ends of the central rod 21, reinforcing plates 22 are arranged. On the reinforcing plates 22, a first support member 23 and two second support members 25 are vertically arranged. In this embodiment, the first support member 23 is a steel plate and the second support member 25 is a steel bar. The first support member 23 is connected to the fixing plate 32 by high-strength bolts 24. The high-strength bolts 24 can achieve the anti-loosening function in combination with existing structures such as gaskets. The end of the second support member 25 is inserted into the groove 34. The central rod 21, the reinforcing plates 22, the first support member 23 and the second support member 25 are integrally formed.

[0027] During construction, first place the connecting plate 30 on the nails 13 at the required height, so that the connecting plate 30 is closely attached to the outer surface of the wing plate 11 of the steel column 10. Then pass the screw rod 31 through the through holes of the connecting plate 30 and fix it with the nut 33 to ensure that the connecting plate 30 will not shift; then find the position, insert the second support member 25 of the support rod 20 into the groove 34, and align the bolt holes of the first support member 23 and the fixing plate 32. Use the high-strength bolts 24 to tighten and lock the first support member 23 and the fixing plate 32 to prevent loosening, so as to fix the support rod 20 between the two steel columns 10. Then carry out other processes. Under the action of this device, the verticality of the steel column 10 is not affected by the subsequent processes and can be kept stable. There is no need to repeatedly measure and correct the small-section steel column, reducing the workload. When the process that will disturb the two steel columns 10 is completed, remove the high-strength bolts 24, the support rod 20, the nuts 33, the screw rods 31 and the connecting plates 30, which can also be used for the next verticality stability work and will not consume too much material.

The diameter of the central rod 21, the diameter of the reinforcing plate 22, the position of the second support member 25 and the grooves 34 can be calculated according to the distance between the two columns of steel pipe columns 10 and the interaction of forces, etc.
