Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a steel tube column and a steel bar beam-slab node connection structure. Background Art

[0002] It is technically difficult to achieve integral connection between traditional circular steel pipe columns and beams and slabs in a structural system, which results in damage to the overall performance of the structure and significantly reduces its seismic resistance.

[0003] The existing connection methods between circular steel pipe columns and steel bars mostly adopt steel column perforation connection and longitudinal reinforcement welding. Both steel column perforation and longitudinal reinforcement welding have a problem of inaccurate positioning, and the steel bars are prone to skew, resulting in structural instability.

[0004] To this end, we propose a node connection structure of steel tube column and reinforced beam-slab. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a steel tube column and steel bar beam-slab node connection structure.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is:

[0007] A steel pipe column and steel bar beam-slab node connection structure comprises: a steel pipe column, which is cylindrical; a plurality of connecting sleeves, which are parallel to each other and fixedly connected to the circumference of the steel pipe column, the tail of the connecting sleeve is fitted and fixed to the circular arc circumference of the steel pipe column, and steel bars are passed through the connecting sleeve; a positioning component, which is sleeved on the steel pipe column, the connecting sleeve is arranged in the positioning component, and the positioning component is used to position the connecting sleeve so that the plurality of connecting sleeves are arranged in parallel.

[0008] By setting a positioning component and passing the connecting sleeve through the positioning component and connecting it to the wall of the steel pipe column, the positioning of the connecting sleeve can be made more accurate without causing deviation. By fitting the tail of the connecting sleeve with the circumference of the steel pipe column, the fixing accuracy of the connecting sleeve can be improved, thereby improving the installation accuracy of the steel bars and ensuring the reliability of the project quality.

[0009] It is further defined that the positioning assembly includes an upper ring, a lower ring, an annular surface and a positioning cylinder, the upper ring and the lower ring are arranged in parallel, the inner diameters of the upper ring and the lower ring match the outer diameter of the steel pipe column, the annular surface is arranged on the outer circumference of the upper ring and the lower ring to connect the upper ring and the lower ring, the number of the positioning cylinder matches the number of the connecting sleeve, and the outer diameter of the connecting sleeve matches the inner diameter of the positioning cylinder, a number of positioning cylinders are arranged in parallel on the inner side of the annular surface, a positioning hole matching the position and inner diameter of the positioning cylinder is opened on the annular surface, and an operating through hole for tools to be inserted is opened on the upper ring or the lower ring; by arranging the upper ring, the lower ring and the annular surface, the positioning cylinder is arranged on the inner side of the annular surface, the connecting sleeve is extended from the positioning cylinder into the positioning assembly and fits with the circumferential surface of the steel pipe column, the cylinder wall of the positioning cylinder can limit the connecting sleeve to prevent it from shifting, at this time, fixing the connecting sleeve to the circumferential surface of the steel pipe column is very accurate, and an operating through hole for tools to be inserted is opened on the upper ring or the lower ring to facilitate personnel to insert into the positioning assembly to complete the fixation between the connecting sleeve and the steel pipe column.

[0010] It is further defined that the upper ring includes an upper inner ring and an upper outer ring, and the lower ring includes a lower inner ring and a lower outer ring, the upper inner ring and the upper outer ring, as well as the lower inner ring and the lower outer ring are fixed by connecting ribs, the annular surface is arranged between the upper outer ring and the upper inner ring, and the gap between the connecting ribs is an operating through hole; by configuring the upper ring to be an upper inner ring and an upper outer ring, and configuring the lower ring to be a lower inner ring and a lower outer ring, and configuring connecting ribs to connect the upper inner ring and the upper outer ring, and the lower inner ring and the lower outer ring, the gap between the connecting ribs as an operating through hole has a larger space, which is more convenient for personnel to operate.

[0011] It is further defined that the tail end face of the connecting sleeve matches the circumferential surface of the steel pipe column at the location and is fixed to the steel pipe column by welding; the connecting sleeve is more firmly fixed to the steel pipe column by welding, and setting the tail end face of the connecting sleeve to an arc surface that matches the circumferential surface of the steel pipe column can further ensure the stability of the welding.

[0012] Further definition, it also includes a fixed sleeve, which is arranged opposite to the connecting sleeve, and the fixed sleeve is arranged on the steel beam. One end of the steel bar is threadedly connected in the connecting sleeve, and the other end is threadedly connected in the fixed sleeve, and the thread rotation direction of the fixed sleeve and the connecting sleeve is the same; in this way, during installation, the connecting sleeve side can be tightened first so that the other end of the steel bar does not intersect with the fixed sleeve, and then the steel bar can be loosened so that the other end of the steel bar is screwed into the fixed sleeve, thereby realizing the connection between the steel pipe column and the steel beam plate.

[0013] It is further defined that the distance between the tail of the positioning tube and the circumference of the steel pipe column is less than the length of the connecting sleeve; setting the length of the connecting sleeve in this way can ensure that the connecting sleeve will not fall out of the positioning tube when in contact with the circumference of the steel pipe column, thereby ensuring the positioning effect of the positioning tube.

[0014] The beneficial effect of the utility model is that by setting a positioning component to position the connecting sleeves, it can be ensured that several connecting sleeves are parallel, which reduces the difficulty of installing the connecting sleeves and the steel pipe column and improves the construction efficiency.
