Description

Technical Field

[0001] This utility model belongs to the field of reinforced concrete structures, specifically, it relates to a steel-concrete beam-column structure. Background Technology

[0002] Steel-concrete composite beam-column structures are increasingly widely used in the construction engineering field due to their good load-bearing capacity, overall stability, and seismic performance. Among these structures, the beam-column joint is a critical and complex stress-bearing component; the rationality of the joint's structural design and the clarity of the force transmission path have a crucial impact on the stability of the beam-column structure. Increasing the density of stirrups at joints is a commonly used measure to improve joint performance. The connection between the beam reinforcement and the steel profile mainly adopts two methods: welding or rebar hole connection. Due to limitations in construction space, welding remains unchanged, while the through-hole method requires a high degree of alignment between the rebar and the rebar holes in the steel profile. However, the steel bars are relatively hard and long, making it difficult to ensure that they are horizontal or vertical during construction, thus increasing the difficulty of aligning the rebar with the rebar holes in the steel profile. Summary of the Invention

[0003] In order to overcome the problems existing in the background technology, this utility model provides a steel-concrete beam-column structure, which can reduce the difficulty of aligning the reinforcing bars and the reinforcing bar holes on the steel section, improve construction efficiency, and increase the connection between the reinforcing bars and the steel section, thereby increasing the overall stability of the structure.

[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions:

[0005] The steel-concrete composite beam-column structure includes steel-concrete composite columns and beams. The steel-concrete composite columns contain steel sections with reinforcing bar holes. A horizontally positioned support plate is welded onto the steel sections. A centering assembly is provided on the support plate. The centering assembly includes an S-shaped adjusting rod, a horizontal rod A, a horizontal rod B, a sleeve, and at least two arc rods. The lower end of the S-shaped adjusting rod has a horizontally welded rod, which is welded to the upper surface of the support plate. The horizontal rod A is connected to the upper end of the S-shaped adjusting rod and is horizontally positioned. The arc rods are welded between horizontal rod A and horizontal rod B. The sleeve is welded to horizontal rod A, horizontal rod B, and the arc rods.

[0006] Preferably, the horizontal bar B is longer than the horizontal bar A, and the right end of the horizontal bar B is flush with the horizontal bar A, while the left end is longer than the horizontal bar A.

[0007] Preferably, the steel section includes a web plate arranged in a cross shape and flange plates welded vertically to the ends of the web plate; the support plate is disposed on the flange plate.

[0008] Preferably, the support plate is disposed on the same side of the wing plate, or on both sides of the wing plate.

[0009] Preferably, the steel section includes cross-shaped webs and flanges vertically welded to the ends of the webs; the support plate is disposed on the webs.

[0010] Preferably, the support plate is disposed on the same side of the web, or disposed on both sides of the web.

[0011] Preferably, the steel section includes a web plate arranged in a cross shape and a flange plate vertically welded to the end of the web plate; the support plate is respectively disposed on the flange plate and the web plate.

[0012] Preferably, the longitudinal reinforcement of the beam passes through the steel reinforcement holes on the steel section and through the entire steel-concrete column.

[0013] The beneficial effects of this utility model are:

[0014] This invention can reduce the difficulty of aligning longitudinal bars with the reinforcing bar holes on the structural steel, improve construction efficiency, and increase the connection strength between the reinforcing bars and the structural steel, thereby increasing the overall stability of the structure.

[0015] Because this invention can reduce the difficulty of aligning longitudinal bars with rebar holes, it makes it easier to make longitudinal bars pass through the entire steel-concrete column during the construction of steel-concrete beams and columns, increasing the robustness of the connection between the steel-concrete column and the beam, and increasing the overall stability of the steel-concrete beam and column structure.

[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] like Figure 1 , 3 As shown in Figure 4, the steel-concrete composite beam-column structure includes a steel-concrete composite column 1 and a beam 2. The structure of this invention allows the longitudinal reinforcement 12 of the beam 2 to completely pass through the entire steel-concrete composite column 1, improving the robustness of the connection between the steel-concrete composite column 1 and the beam 2. Compared to existing structures, the difficulty of centering adjustment during the passing process is reduced, improving the construction efficiency of the longitudinal reinforcement 12 passing through the rebar holes in the steel section, and enhancing the connection between the steel-concrete composite column 1 and the beam 2.

[0025] The steel-concrete composite column 1 is a conventional structure containing steel sections. These sections include cross-shaped webs 4 and flanges 5 vertically welded to the ends of the webs 4. Rebar holes for longitudinal reinforcement 12 are formed on both the webs 4 and flanges 5. The most important component of this invention, which reduces the difficulty of aligning the longitudinal reinforcement 12 with the rebar holes and improves the efficiency of the longitudinal reinforcement 12 passing through, is the alignment component 20. In this embodiment, depending on the construction conditions, the longitudinal reinforcement 12 is positioned on the same side of the webs 4 and flanges 5: for example... Figure 1 As shown, during construction, the longitudinal reinforcement 12 is inserted into the steel section from the left side, and the centering assembly 20 is respectively set on the left side of the web 4 and the flange 5. The longitudinal reinforcement 12 is inserted into the steel reinforcement hole after being aligned with the steel reinforcement hole on the steel section by the centering assembly 20.

[0026] A support plate 3 is welded onto the structural steel. After welding, the support plate 3 is horizontal, and the centering assembly 20 is fixed to the support plate 3. The centering assembly includes a horizontal welding rod 11, an S-shaped adjusting rod 6, a horizontal rod A7, a horizontal rod B8, a sleeve 9, and two arc rods 10. The horizontal welding rod 11 and the horizontal rod A7 are welded to the upper and lower ends of the S-shaped adjusting rod 6, respectively. The horizontal welding rod 11 is welded to the support plate 3, fixing and supporting the centering assembly 20 on the support plate 3. The sleeve 9 is welded to the horizontal rod A7, the horizontal rod B8, and the arc rods 10. The welding of the sleeve 9 can be done by spot welding. After centering, concrete needs to be poured. Therefore, the centering assembly mainly plays a role when inserting the longitudinal reinforcement 12, so the welding strength requirement for the sleeve 9 is not high. After the horizontal welding rod 11 is welded to the support plate 3, the horizontal rod A7 needs to be kept as horizontal as possible. Two arc rods 10 are provided, and both arc rods 10 are welded between the horizontal rod A7 and the horizontal rod B8. After welding, the horizontal rods A7 and B8 need to be as horizontal as possible to ensure that the welded sleeve 9 is in a horizontal state. This makes it easier for the longitudinal reinforcement 12 to be inserted into the sleeve 9, and also facilitates the alignment of the sleeve 9 and the longitudinal reinforcement 12 with the rebar hole. This utility model provides support for the centering component 20 by setting the support plate 3. The S-shaped adjustment rod 6 in the centering component 20 has an S-shaped structure that makes it easier to adjust the left, right, up, and down positions during centering, reducing the difficulty of centering operations and improving centering efficiency. Except for the sleeve 9, the centering component 20 of this utility model adopts a rod-shaped structure. There are two main reasons for this: First, the centering component 20 can be discarded after the centering construction (unless otherwise specified in this utility model, centering refers to the centering of the longitudinal reinforcement 12 with the reinforcement hole on the steel section), so the requirements for its strength and connection firmness are low; second, the rod-shaped structure requires less force to adjust left, right, up and down during centering, reducing the difficulty of centering operation; and third, it can reduce processing costs.

[0027] The alignment operation demonstration of this utility model is as follows: When alignment is required, first insert the end of the longitudinal reinforcement 12 into the sleeve 9. During alignment, hold the sleeve 9 to align it with the longitudinal reinforcement 12, and insert the tail end of the longitudinal reinforcement 12 into the sleeve 9. Under the constraint of the sleeve 9, the longitudinal reinforcement 12 is basically horizontal. Then, make minor adjustments to the sleeve 9 and the longitudinal reinforcement 12 to align the longitudinal reinforcement 12 with the rebar hole and smoothly insert the longitudinal reinforcement 12 into the rebar hole. In the initial design of this utility model, the S-shaped adjusting rod 6 was designed as a plate structure, which only allowed for vertical adjustment of the sleeve 9, while the horizontal adjustment range was very limited. After changing it to a rod shape, the horizontal adjustment range was significantly increased, enabling rapid alignment.

[0028] As a preferred embodiment, horizontal bar B8 is longer than horizontal bar A7, with its right end flush with and its left end longer than horizontal bar A7. This structure increases the support length of sleeve 9, making it easier to maintain the level of sleeve 9. Furthermore, during adjustment, the force point is closer to the middle of sleeve 9, further improving its levelness and alignment efficiency. The inventors previously attempted to design horizontal bar B8 to be the same length as horizontal bar A7, with the left end of horizontal bar A7 welded to S-shaped adjusting rod 6. However, this design caused sleeve 9 to easily tilt during adjustment due to the opposing force of S-shaped adjusting rod 6 on horizontal bar A7, making alignment difficult. Welding the middle of horizontal bar A7 to S-shaped adjusting rod 6 not only increases the processing steps of the alignment assembly 20 but also results in weak welds between horizontal bar A7 and S-shaped adjusting rod 6, occasionally leading to breakage of both during alignment work. By increasing the length of the horizontal bar B8, not only can the processing difficulty of the centering component 20 be reduced, but it is also more conducive to maintaining the parallel state of the sleeve 9.

[0029] As attached Figure 2 As shown, as an optional solution, the support plate 3 can be set on both sides of the web plate 4 and the flange plate 5 respectively. In this way, no matter which direction the longitudinal reinforcement 12 is constructed from, it can be quickly aligned, increasing the flexibility of construction.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
