Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a complex node structure for adding a large load-bearing frame beam in a newly added structural mezzanine. Background Technology

[0002] In traditional structural alterations, the addition of new frame beams generally does not require widening or reinforcing the columns. The new frame beams are usually reconstructed by installing rebar on the side of the column.

[0003] When encountering newly added structural mezzanine layers with large loads, requiring column widening and reinforcement, as well as large load-bearing frame beams, the traditional rebar installation method cannot be used due to the large number of main reinforcement bars in the newly added frame beams. Therefore, more complex node construction is required.

[0004] Based on this, this utility model proposes a complex node structure for adding a large load-bearing frame beam in a newly added structural mezzanine. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a complex node structure for a newly added large load-bearing frame beam in a new structural mezzanine, which solves the problem of difficult construction of beam-column nodes for large load-bearing beams in a newly added structural mezzanine, thus improving both economy and safety.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a complex node structure for adding a large load-bearing frame beam in a newly added structural mezzanine, including a concrete column and longitudinal reinforcement inside the column. The longitudinal reinforcement inside the column is set inside the concrete column. Multiple sets of vertical main reinforcement are fixedly installed at equal intervals on the outside of the concrete column. Reinforcing tie bar 1, reinforcing tie bar 2 and reinforcing tie bar 3 are fixedly installed between every three adjacent sets of vertical main reinforcement bars. A ring stirrup 1 is welded and fixed between multiple vertical main reinforcement bars. It also includes a reinforcing ring beam.

[0007] The reinforcing ring beam is installed at the end of the concrete column.

[0008] The reinforced ring beam includes multiple annular stirrups II, and multiple ring beam tie rods I, II, and III are fixedly installed among the multiple annular stirrups II.

[0009] In some embodiments, the ends of the second reinforcing bar and the second ring beam reinforcing bar are both anchored into the interior of the concrete column, the first reinforcing bar and the third ring beam reinforcing bar are welded and fixed to the longitudinal reinforcement bars in the column, and the end of each of the vertical main bars extends into the interior of the reinforcing ring beam.

[0010] In some embodiments, multiple longitudinal reinforcement bars 1 are fixedly installed on three adjacent sides of the concrete column, multiple longitudinal reinforcement bars 3 are fixedly installed on the middle of one side of the concrete column, multiple longitudinal reinforcement bars 2 and 4 are respectively provided on both sides of the longitudinal reinforcement bars 1 and 3, multiple stirrup bars 1 are fixedly installed at equal intervals between the longitudinal reinforcement bars 1 and 2, and multiple stirrup bars 2 are fixedly installed at equal intervals between the longitudinal reinforcement bars 3 and 4.

[0011] In some embodiments, the ends of the longitudinal reinforcement bars 1 and 3 located on both sides of the beam are anchored into the interior of the concrete column, while the longitudinal reinforcement bars 1 and 3 located in the middle of the beam are anchored into the interior of the reinforcing ring beam.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model strengthens the original concrete column by reinforcing it, thereby increasing the structural strength of the concrete column and providing stable support for the newly added large load-bearing frame beam. This ensures that the newly added frame beam can bear a large load. Furthermore, by adding a reinforcing ring beam at the joint, the structural strength at the joint between the concrete column and the newly added frame beam is further improved, thus further enhancing the stability of the joint.

[0014] Secondly, this utility model widens and strengthens the original concrete column and adds a reinforcing ring beam at the end node, which is not only low in cost and simple to construct, but also effectively strengthens and supports the structure, thereby improving the load-bearing capacity of the newly added frame beam.

[0015] This solves the problem that when the existing new structural mezzanine has a large load and requires column widening and reinforcement, as well as when there are large load-bearing frame beams, the traditional rebar installation method cannot be used for construction due to the large number of main reinforcement bars in the new frame beams.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved, complex node structure for adding a large load-bearing frame beam in a newly added structural mezzanine. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, a complex node structure for adding a large load-bearing frame beam in a newly added structural mezzanine includes a concrete column 1 and longitudinal reinforcement 2 inside the column. The longitudinal reinforcement 2 is located inside the concrete column 1. Multiple sets of vertical main reinforcement 3 are fixedly installed at equal intervals on the outside of the concrete column 1. Reinforcing tie bars 1-5, 2-6, and 3-7 are fixedly installed between every three adjacent sets of vertical main reinforcement 3. A ring stirrup 4 is welded and fixed between the multiple vertical main reinforcement 3. The structure also includes a reinforcing ring beam 8. The multiple sets of vertical main reinforcement 3 and multiple tie bars can effectively widen and reinforce the concrete column 1, thereby improving the stability and support effect of the concrete column 1.

[0025] Reinforcing ring beam 8 is installed at the end of concrete column 1.

[0026] The reinforced ring beam 8 includes multiple annular stirrups 2 9, and multiple ring beam tie bars 1 10, ring beam tie bars 2 11 and ring beam tie bars 3 12 are fixedly installed together among the multiple annular stirrups 2 9. The overall structural strength of the reinforced ring beam 8 is achieved by the multiple annular stirrups 2 9 working together with the ring beam tie bars.

[0027] Furthermore, the ends of the reinforcing tie 6 and the ring beam tie 11 are anchored into the interior of the concrete column 1. The reinforcing tie 5 and the ring beam tie 12 are welded and fixed to the longitudinal reinforcement 2 inside the column. The end of each vertical main reinforcement 3 extends into the interior of the reinforcing ring beam 8. By connecting the reinforcing tie 6 and the ring beam tie 11 to the interior of the concrete column 1, the stability of the reinforced steel cage is improved. Welding the reinforcing tie 5 and the ring beam tie 12 to the longitudinal reinforcement 2 inside the column further improves the stability of the overall structure, thereby improving the structural stability of the widened and reinforced concrete column 1.

[0028] Furthermore, multiple longitudinal reinforcement bars 13 are fixedly installed on three adjacent sides of the concrete column 1, and multiple longitudinal reinforcement bars 36 are fixedly installed in the middle of one side of the concrete column 1. Multiple longitudinal reinforcement bars 24 and 47 are respectively set on both sides of the longitudinal reinforcement bars 13 and 36. Multiple stirrup bars 15 are fixedly installed at equal intervals between longitudinal reinforcement bars 13 and 24, and multiple stirrup bars 28 are fixedly installed at equal intervals between longitudinal reinforcement bars 36 and 47. The longitudinal reinforcement bars 13 and 36 can provide a stable foundation for the later pouring of the frame beam. The longitudinal reinforcement bars 214 have a slope of 1:6 to avoid the original frame column, and together with the longitudinal reinforcement bars 13, they can ensure the stable load-bearing capacity of the frame beam in the later stage.

[0029] Furthermore, the ends of the longitudinal reinforcement bars 13 and 36 located on both sides of the beam are anchored into the interior of the concrete column 1, and the longitudinal reinforcement bars 13 and 36 located in the middle of the beam are anchored into the interior of the reinforcing ring beam 8. By anchoring the longitudinal reinforcement bars 13 and 36 located on both sides of the beam into the interior of the concrete column 1, the stability of the middle part of the frame beam reinforcement cage is improved.

[0030] The specific working method is as follows: First, the original concrete column 1 is widened and reinforced, and the beam-column joint is roughened and cleaned, and an interface agent is applied. Two rows of vertical main reinforcement bars 3 are installed on the concrete column 1, both anchored into the reinforced ring beam 8 at the beam-column joint. Reinforcing ties 1-5, 2-6, and 3-7 with a diameter of 16mm are installed. When encountering longitudinal reinforcement bars 2 within the column, they are welded for fixation; if there are no longitudinal reinforcement bars 2, they are anchored. 20mm diameter ring stirrups 4 are installed and welded together. When constructing the reinforced ring beam 8 for the newly added large load-bearing beam-column joint, two rows of four 25mm ring stirrups 9 are used as the main reinforcement bars and connecting rods of the reinforced ring beam 8. Interlocking welding is used; the ring beam tie bars 10, 11, and 12 are equidistant with a diameter of 16mm and a spacing of 200mm; finally, the reinforcement binding of the large load-bearing beam is carried out, and the outermost two longitudinal bars of the beam 13 are anchored into the concrete column 1; the remaining intermediate longitudinal bars 13 are anchored into the beam-column joint reinforcement ring beam 8; the four longitudinal bars 214 on both sides of the beam avoid the original frame column through-column reinforcement and reinforcement ring beam 8, forming a haunch; then the beam stirrups 15 are used for binding; after all the reinforcement binding is completed, after the formwork is reinforced, a higher grade micro-expansion concrete is poured. Through the above complex node construction, the problem of difficult construction of beam-column joints of large load-bearing beams in newly added structural mezzanines can be solved, and both economy and safety are improved.

Matters not covered in this utility model are common knowledge to those skilled in the art.
