Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reinforcing piece for connecting a steel structure column corbel with a concrete beam elevation steel bar. Background Art

[0002] With the rapid development of modern construction technology, composite structures have been widely used in various high-rise and long-span buildings due to their excellent load-bearing and deformation capabilities. Since steel columns and concrete beams are inevitable in engineering, the connection between steel columns and concrete beams is extremely important and often becomes a difficult point in actual engineering.

[0003] In the existing technology, commonly used methods for connecting steel columns to concrete beams include through-rebar, connectors, ribbed plates, corbel connections, and ring beams. However, the problem with connecting concrete beam reinforcement to steel columns is that a single corbel on the steel column cannot support the connection between multiple rows of non-column-wrapped reinforcement and the steel column flange. This makes it impossible to connect multiple rows of concrete beam reinforcement to the steel column flange.

[0004] Therefore, based on the above technical problems, technical personnel in this field urgently need to develop reinforcement parts for connecting steel structure column corbels and concrete beam elevation steel bars. Utility Model Content

[0005] The purpose of the utility model is to provide a reinforcement part for connecting the steel structure column corbel with the concrete beam elevation steel bar by combining the corbel support and the sleeve support to meet the structural connection of multiple rows of steel bars in a concrete beam and larger steel columns.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The reinforcement member for connecting a steel structure column corbel with a concrete beam elevation steel bar of the utility model comprises a steel structure column body, a corbel connected to the flange plate side of the steel structure column body, and steel bars for connecting the concrete beam on the flange plate side of the steel structure column body and the corbel, wherein the steel bars of the concrete beam comprise a first row of upper bars, a second row of upper bars, a first row of lower bars, and a second row of lower bars;

[0008] The first row of upper ribs and the first row of lower ribs are welded to the corbel;

[0009] The second row of upper ribs and the second row of lower ribs are both connected to the steel structure column by arranging sleeves, and the sleeves are welded to the steel structure column.

[0010] Furthermore, the first row of upper ribs is located in the middle position and the portion above the top of the corbel is welded to the corbel, and the first row of upper ribs located on both sides of the middle position are connected to the steel structure column through the sleeve.

[0011] Furthermore, the first row of lower ribs located in the middle position and the portion located above the bottom of the corbel is welded to the corbel, and the first row of lower ribs located on both sides of the middle position are connected to the steel structure column through the sleeve.

[0012] Furthermore, it also includes an external bracket structure, which is arranged in the middle part of the corbel to support the sleeve, and the external bracket structure is arranged on both sides of the middle part of the corbel.

[0013] Furthermore, the external bracket structure includes:

[0014] A vertical plate, the vertical plate being fixedly connected to the middle portion of the corbel by bolts;

[0015] Transverse supporting plates, which are multiple groups connected to the side surfaces of the vertical plates and used to support the bottom of the sleeve; and

[0016] A reinforcing rib is connected between the side surface of the vertical plate and the bottom surface of the horizontal supporting plate to support the horizontal supporting plate.

[0017] In the above technical solution, the reinforcement piece for connecting the steel structure column corbel with the concrete beam elevation steel bar provided by the utility model has the following beneficial effects:

[0018] The corbels provided on the steel structure columns of the present invention are only connected by welding to the first row of upper reinforcement located at the upper end of the concrete beam and the first row of lower reinforcement located at the upper and lower ends of the concrete beam in the middle position. The steel bars in other positions are connected to the steel structure columns by providing sleeves. For example, the first row of upper reinforcement and the first row of lower reinforcement on both sides of the middle position, as well as the second row of upper reinforcement and the second row of lower reinforcement that cannot be supported by the corbels, are all connected to the steel structure columns by sleeves. The combination of corbel support and sleeve support satisfies the structural connection between multiple rows of steel bars in the concrete beam and larger steel columns. This method has better stress resistance than the single form of multiple layers of corbels or multiple layers of sleeves and is convenient for construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See also Figures 1 to 2 As shown;

[0026] This embodiment discloses a reinforcement member for connecting a steel structure column corbel with a concrete beam elevation reinforcement, comprising a steel structure column 1, a corbel 2 connected to the flange side of the steel structure column 1, and reinforcement bars for connecting the concrete beam on the flange side and the corbel 2. The reinforcement bars of the concrete beam include the first row of upper reinforcement bars 3, the second row of upper reinforcement bars 4, the first row of lower reinforcement bars 5, and the second row of lower reinforcement bars 6; wherein the first row of upper reinforcement bars 3 is the row of reinforcement bars located at the top of the concrete beam, the second row of upper reinforcement bars 4 is the row of reinforcement bars located below the first row of upper reinforcement bars 3, the first row of lower reinforcement bars 5 is the row of reinforcement bars located at the bottom of the concrete beam, and the second row of lower reinforcement bars 6 is the row of reinforcement bars located above the first row of lower reinforcement bars 5. In this embodiment, only the above four rows of reinforcement bars are taken as an example, and this technology is not limited to the above four rows of reinforcement bars.

[0027] The first row of upper ribs 3 and the first row of lower ribs 5 are both welded to the corbel 2. Specifically, the first row of upper ribs 3 are welded to the top of the corbel 2, and the first row of lower ribs 5 are welded above the transverse wing plate at the bottom of the corbel 2 so that they can be supported by the corbel 2.

[0028] The second row of upper bars 4 and the second row of lower bars 6 are both connected to the steel structure column 1 by setting a sleeve 7. The sleeve 7 is welded to the steel structure column 1 so that the ends of the second row of upper bars 4 and the second row of lower bars 6 can be extended into the sleeve 7 for connection. The sleeve 7 can be installed and connected like the connector method in the connection form of steel frame column and concrete beam in the prior art.

[0029] Furthermore, the first row of upper reinforcement 3 is located in the middle position and the part above the top of the corbel 2 is welded to the corbel 2, and the first row of upper reinforcement 3 on both sides of the middle position is connected to the steel structure column 1 through the sleeve 7.

[0030] Furthermore, the first row of lower ribs 5 located in the middle position and the portion above the bottom of the corbel 2 is welded to the corbel 2 , and the first row of lower ribs 5 located on both sides of the middle position are connected to the steel structure column 1 through sleeves 7 .

[0031] Specifically, when the width of the steel column is large, and the number of upper first-row bars 3 exceeds the width of the corbel 2, a single corbel 2 cannot fully support the entire structure. In this case, the middle upper first-row bars 3 are welded to the corbel 2, while the remaining upper first-row bars 3 are connected to the steel column 1 via sleeves 7. The same principle applies to the lower first-row bars 5. This allows for the structural connection of multiple rows of steel bars in a concrete beam to a larger steel column. This approach also provides better stress resistance than a single structure with multiple layers of corbels or sleeves, and is convenient for construction. Both the upper second-row bars 4 and the lower second-row bars 6 are connected to the steel column 1 via sleeves 7.

[0032] Furthermore, for the steel bars in other positions except the first row of bars 3 of the upper bars and the first row of bars 5 of the lower bars that cannot be supported by the corbel 2, after being connected through the sleeve 7, in order to continue to improve the stability of the connection, the sleeve 7 needs to be further reinforced and supported. Therefore, the technical solution of the present application also includes an external bracket structure, which is arranged in the middle part of the corbel 2 to support the sleeve 7, and external bracket structures are arranged on both sides of the middle part of the corbel 2 to reinforce and support the sleeves 7 on both sides of the corbel 2.

[0033] Furthermore, the external bracket structure includes:

[0034] The vertical plate 8 is fixedly connected to the middle part of the corbel 2 by bolts so that the external bracket structure is integrally mounted on the corbel 2;

[0035] Horizontal support plates 9 are multiple groups connected to the sides of the vertical plates 8 to support the bottom of the sleeve 7. The number of horizontal support plates 9 depends on the specific number of rows of steel bars. While supporting the sleeve 7, the sleeve 7 can also be directly welded to the horizontal support plates 9 to achieve further fixed connection according to the situation; and

[0036] The reinforcing ribs 10 are connected between the side of the vertical plate 8 and the bottom of the horizontal support plate 9 to support the horizontal support plate 9, so as to reinforce the horizontal support plate 9 and make the horizontal support plate 9 support the sleeve 7 more stably, or support more sleeves 7 in a horizontal row.

[0037] In the above technical solution, the reinforcement piece for connecting the steel structure column corbel with the concrete beam elevation steel bar provided by the utility model has the following beneficial effects:

[0038] The corbels provided on the steel structure columns of the present invention are only connected by welding to the first row of upper reinforcement located at the upper end of the concrete beam and the first row of lower reinforcement located at the upper and lower ends of the concrete beam in the middle position. The steel bars in other positions are connected to the steel structure columns by providing sleeves. For example, the first row of upper reinforcement and the first row of lower reinforcement on both sides of the middle position, as well as the second row of upper reinforcement and the second row of lower reinforcement that cannot be supported by the corbels, are all connected to the steel structure columns by sleeves. The combination of corbel support and sleeve support satisfies the structural connection between multiple rows of steel bars in the concrete beam and larger steel columns. This method has better stress resistance than the single form of multiple layers of corbels or multiple layers of sleeves and is convenient for construction.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
