Description

Technical Field

[0001] The utility model relates to the field of building structures, in particular to an anchoring structure of a steel pipe column at a beam-column node of a cast-in-place concrete garage roof. Background Art

[0002] The base of a steel pipe column can be exposed, embedded, or externally packaged. When a basement ceiling exists, there are two common approaches. One is to use an exposed base, which does not require high aesthetics; the other is to use an embedded base, which can well meet the aesthetic requirements of architectural decoration. However, the embedded section of the steel pipe column is located at the node, where beams and columns intersect and rebar intersects. Especially when beams at different elevations intersect, multiple layers of rebar need to be anchored into the node. Currently, holes are typically drilled in the circumferential wall of the steel pipe column to allow for perforated anchoring of concrete beam rebar, or steel brackets are installed for rebar welding connections. Both of these situations require high construction requirements, requiring precise holes to be reserved and accurately positioned at the construction site. Otherwise, positional and directional deviations will occur during on-site construction, making it impossible to anchor the concrete frame beam rebar. Re-drilling and adjustment on-site are more difficult.

[0003] Therefore, how to design an anchoring structure that is convenient to construct and reliable is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] The purpose of the utility model is to address the deficiencies of the existing technology and provide an anchoring structure for steel pipe columns in the beam-column nodes of cast-in-place concrete garage roofs. The structure is suitable for anchoring beams and nodes at any angle and different elevations, and can be locally adjusted on site to facilitate construction.

[0005] The technical solution of the utility model is: an anchoring structure of a steel pipe column at the beam-column node of a cast-in-place concrete garage roof, comprising a steel pipe column, the lower end of the steel pipe column is provided with a fixing plate for bolts to pass through and temporarily fix to the concrete column, a plurality of groups of studs are arranged at intervals along the height direction on the outer peripheral wall of the pipe section of the steel pipe column corresponding to the beam height, and the studs of each group are evenly distributed along the circumference of the steel pipe column, and also include a group of inner ring reinforcement and a plurality of groups of outer ring reinforcements of different diameters, the number of the inner ring reinforcements does not exceed the number of groups of studs, a plurality of horizontal tension bars are fixedly arranged on the inner ring reinforcement, the plurality of horizontal tension bars are distributed along the circumference of the inner ring reinforcement and extend radially outward, the number of outer ring reinforcements in the same group is the same as the number of inner ring reinforcements, the inner ring reinforcements are supported on the corresponding groups of studs, the outer ring reinforcements of different diameters are respectively supported on the corresponding horizontal tension bars, and are fixed by the ring beam stirrups to form a steel cage, forming a space for the beam reinforcement to be inserted, and the anchoring structure is formed by pouring concrete.

[0006] The inner ring reinforcement is formed into a whole by welding two half ring reinforcements, and the inner ring reinforcement is concentric with the steel pipe column.

[0007] The fixing plate is provided with a plurality of holes for the bolts to pass through, and the holes are evenly distributed along the circumference of the steel pipe column.

[0008] The radial spacing between adjacent outer ring ribs is the same and ≤150mm.

[0009] Multiple groups of studs are evenly spaced along the height direction of the steel pipe column.

[0010] The multiple horizontal reinforcements are divided into multiple groups, and the multiple groups of horizontal reinforcements are evenly distributed along the circumference of the inner ring reinforcement.

[0011] The above technical solution has the following beneficial effects:

[0012] 1. The anchoring structure for a steel pipe column at the beam-column joint of a cast-in-place concrete garage roof includes a steel pipe column with a fixing plate at its lower end for bolts to be temporarily secured to the concrete column. This allows the steel pipe column to be temporarily secured to the beam via the fixing plate. Multiple groups of studs are spaced along the height of the steel pipe column's outer wall at the corresponding beam height. Each group of studs is evenly distributed along the circumference of the steel pipe column, and the stud height can be adjusted based on the position of the beam reinforcement. The structure also includes inner ring reinforcement and multiple groups of outer ring reinforcement of varying diameters. The number of inner ring reinforcements does not exceed the number of groups of studs. Multiple horizontal tie bars are fixed to the inner ring reinforcement, distributed circumferentially and extending radially outward. The number of outer ring reinforcements in a given group is the same as the number of inner ring reinforcements. The inner ring reinforcements are supported on corresponding groups of studs. In other words, the inner ring reinforcements are spaced along the height of the steel pipe column, and their height can be adjusted as needed to meet the anchoring requirements of beams of varying elevations. Outer ring bars of varying diameters are supported on corresponding horizontal reinforcement bars. Once the inner ring bars are positioned, the outer ring bars can be quickly installed and their positions determined, improving the processing efficiency of the anchoring structure and ensuring the safety of the node structure. The ring beam stirrups are fixed to form a reinforcement cage, creating space for the beam reinforcement to be inserted. This requires minimal precision in positioning the beam reinforcement, and the position of the ring beam stirrups can be adjusted locally on-site to meet the actual needs of on-site construction. The anchoring structure, formed by pouring concrete, effectively solves the anchoring problem of steel pipe columns and beam reinforcement and facilitates on-site construction.

[0013] 2. The inner ring reinforcement is formed by welding two half ring reinforcements into a whole. The inner ring reinforcement is concentric with the steel pipe column, which makes it convenient to install the inner ring reinforcement on the corresponding group of studs, ensures the stability of the inner ring reinforcement, and avoids interference.

[0014] The following is a further description with reference to the accompanying drawings and specific implementations. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figures 1 to 3 This is a specific embodiment of a steel pipe column anchoring structure at a beam-column joint in a cast-in-place concrete garage roof. The anchoring structure includes a steel pipe column 1, with a fixing plate 2 at its lower end for bolts to pass through and temporarily secure to the concrete column. Specifically, the fixing plate 2 is provided with multiple holes for bolts to pass through, evenly distributed along the circumference of the steel pipe column 1. Multiple groups of studs 3 are spaced apart along the height of the outer wall of the section of the steel pipe column 1 corresponding to the beam height, and each group of studs is evenly distributed along the circumference of the steel pipe column 1. In this embodiment, there are thirteen groups of studs 3, evenly spaced along the height of the steel pipe column 1, with each group containing twenty studs. The structure also includes a set of inner ring reinforcements 4 and multiple sets of outer ring reinforcements 5 of varying diameters. The number of inner ring reinforcements 4 does not exceed the number of groups of studs 3, i.e., the number of inner ring reinforcements does not exceed thirteen. Specifically, the number of inner ring reinforcements is ten. A plurality of horizontal reinforcement bars 6 are fixedly provided on the inner ring reinforcement 4. The plurality of horizontal reinforcement bars 6 are distributed along the circumference of the inner ring reinforcement 4 and extend radially outward. Usually, the plurality of horizontal reinforcement bars are divided into a plurality of groups. The plurality of groups of horizontal reinforcement bars are evenly distributed along the circumference of the inner ring reinforcement. In this embodiment, the horizontal reinforcement bars are divided into four groups. The number of horizontal reinforcement bars in each group is three. That is, the space between adjacent groups of horizontal reinforcement bars can be used for the insertion of beam reinforcement bars. The number of outer ring reinforcement bars 5 in the same group is the same as the number of inner ring reinforcement bars 4. Specifically, the number of groups of outer ring reinforcement bars is four groups, and the number of outer ring reinforcement bars in the same group is ten. The inner ring reinforcement 4 is supported on the corresponding group of bolts 3. In this embodiment, the inner ring reinforcement is supported on ten groups of bolts on the upper part of the steel pipe column. In order to avoid interference with the bolts during installation, the inner ring reinforcement 4 is formed as a whole by welding two half ring reinforcements. The inner ring reinforcement 4 is concentric with the steel pipe column 1. Outer ring reinforcements 5 of different diameters are supported on corresponding horizontal reinforcements 6 and fixed by ring beam stirrups 7 to form a reinforcement cage, forming a space for the insertion of beam reinforcements. In order to meet the installation standards, the radial spacing distance between adjacent outer ring reinforcements 5 is the same and ≤150mm, and the anchoring structure is formed by pouring concrete.

[0020] The present invention connects the beam reinforcement to the steel pipe column using bolts to temporarily secure the anchor structure to the pre-determined concrete column. Studs, inner and outer ring reinforcement are then installed as needed, and a reinforcement cage is formed by circumferential beam stirrups. The beam reinforcement is then inserted horizontally into the cage, secured with ties, and concrete is poured into the cage to form the anchor structure of the beam-column joint. Concrete is then poured into the steel pipe column to form the concrete column.
