Description

Technical Field

[0001] This utility model belongs to the technical field of beam-column connection structure, and particularly relates to a combined structure for fixing steel-concrete columns and steel bars at the ends of concrete beams. Background Technology

[0002] Steel-concrete composite structures are widely used in high-rise buildings due to their superior wind and earthquake resistance and overall good economic benefits. A common joint in steel-concrete composite structures is the connection between the longitudinal reinforcement of the steel-concrete composite columns and the concrete beams. Several common methods are used: 1. Pre-drilling holes in the steel column, with the reinforcing bars passing through; 2. Connecting the longitudinal reinforcement of the steel column and beam using steel brackets. The steel brackets are welded onto the steel column, and the longitudinal reinforcement of the beam is welded to the steel brackets on-site.

[0003] The above-mentioned method of pre-drilling holes in steel columns is prone to damaging the pre-drilled holes in the steel columns, affecting the structural strength of the steel columns, and is no longer used on a large scale. The welding method, which can avoid damaging the steel columns, requires on-site high-altitude operations, which is complicated and time-consuming, and the connection process involves high-altitude operations, resulting in poor construction safety. Utility Model Content

[0004] This utility model provides a combined structure for fixing steel-concrete columns and concrete beam end reinforcement, aiming to solve the problems of current construction methods that require on-site high-altitude operations, are cumbersome and time-consuming, and have poor construction safety due to high-altitude operations involved in the connection process.

[0005] This utility model is implemented as follows: a combined structure for fixing steel-concrete composite columns and concrete beam end reinforcement, comprising:

[0006] The steel columns and concrete beams are connected by several sets of longitudinal steel bars between adjacent steel columns, and the concrete beams are covered by the outer side of the several sets of longitudinal steel bars.

[0007] The steel column is provided with a bracket, which includes a first assembly plate, a connecting frame and a second assembly plate. The first assembly plate is provided with several sets of first mounting slots with openings facing the sky, and the second assembly plate is provided with several sets of first mounting slots and second mounting slots that are inclined towards the ground.

[0008] The longitudinal reinforcing bar includes a reinforcing bar sleeve and a reinforcing bar. After the reinforcing bar is pushed into the first mounting groove or the second mounting groove, the reinforcing bar sleeve is nested at the end of the reinforcing bar and engages the reinforcing bar in the first mounting groove or the second mounting groove.

[0009] Preferably, the second mounting groove includes a guide groove with its opening angled towards the ground and an assembly groove with its opening angled towards the sky. The guide groove and the assembly groove are connected to each other. When the reinforcing bar is pushed into the guide groove, it moves away from the ground. After reaching the end of the guide groove, it enters the assembly groove and moves back towards the ground.

[0010] Preferably, the second assembly plate is provided with several sets of first mounting slots and second mounting slots pointing obliquely to the ground, each corresponding to a specific position. The positions of the longitudinal steel bars in the first and second mounting slots are also corresponding to each other.

[0011] Preferably, the connecting frame is welded to the steel column, and the first assembly plate and the second assembly plate are spaced apart from the steel column through the connecting frame to form an installation gap.

[0012] Preferably, the two ends of the reinforcing bar extend beyond the first or second assembly plate into the installation gap, and the reinforcing bar sleeve is assembled on the portion of the reinforcing bar that extends into the installation gap.

[0013] Preferably, the inner wall of the rebar sleeve is threaded, and both ends of the rebar are threaded to match it. The rebar sleeve is nested inside the end of the rebar and is threadedly connected to the rebar.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a combined structure for fixing steel-concrete composite columns and concrete beam end reinforcement, such as... Figures 1-5 As shown, the combined structure of the steel-concrete composite column and the end reinforcement of the concrete beam includes:

[0026] A steel column 100 is provided, and several sets of longitudinal steel reinforcement members 400 are provided between adjacent steel columns 100. The concrete beam is covered on the outside of the several sets of longitudinal steel reinforcement members 400.

[0027] The steel column 100 is provided with a bracket 300. The bracket 300 includes a first assembly plate 310, a connecting frame 320 and a second assembly plate 330. The first assembly plate 310 is provided with a number of first mounting slots 301 with openings facing the sky. The second assembly plate 330 is provided with a number of first mounting slots 301 and second mounting slots that are inclined towards the ground.

[0028] The longitudinal reinforcing bar 400 includes a reinforcing bar sleeve 410 and a reinforcing bar 420. After the reinforcing bar 420 is pushed into the first mounting groove 301 or the second mounting groove, the reinforcing bar sleeve 410 is nested around the end of the reinforcing bar 420 and engages the reinforcing bar 420 in the first mounting groove 301 or the second mounting groove.

[0029] In this application, the steel column 100 and the connecting frame 320 are pre-welded together during factory processing. The connecting frame 320 adopts an I-shaped structure, and its width needs to be greater than the length of the rebar sleeve 410. The first assembly plate 310 and the second assembly plate 330 maintain a distance from the steel column 100 through the connecting frame 320 to form an installation gap. The two ends of the rebar 420 extend beyond the first assembly plate 310 or the second assembly plate 330 into the installation gap. The rebar sleeve 410 is assembled on the part of the rebar 420 that extends into the installation gap. After the longitudinal rebar 400 and the corbel 300 are connected, a formwork for the concrete beam 200 is constructed on the outside of the corbel 300 and the longitudinal rebar 400. The formwork is removed after the concrete beam 200 is poured.

[0030] It should be noted that, in order to understand the connection relationship between the corbel 300 and the longitudinal reinforcing bar 400, this application therefore... Figure 1 The concrete beam 200 provided does not enclose the corbel 300. In the actual process, the formwork of the concrete beam 200 is simultaneously wrapped around the corbel 300, the steel sleeve 410 and the outer side of the end of the steel bar 420. All of the above structures are ultimately located inside the concrete beam 200.

[0031] This application mainly simplifies the connection steps between the steel column 100 and the longitudinal steel bar 400 by using the bracket 300. Through the cooperation of the specially designed installation groove and the steel bar sleeve 410, the complex welding operation of the steel column 100 on the construction site is avoided, and the longitudinal steel bar 400 can be quickly connected to the steel column 100, thereby reducing the time and steps of high-altitude operation and improving the safety of the construction process.

[0032] As a preferred embodiment of this embodiment, the second assembly plate 330 is provided with a plurality of first mounting slots 301 and second mounting slots pointing obliquely to the ground, and the positions of the longitudinal steel bars 400 in the first mounting slots 301 and the second mounting slots are also in one-to-one correspondence.

[0033] In this embodiment, the lower end face of the concrete beam 200 is usually subjected to greater compressive strength than the upper end face. Therefore, the second assembly plate 330 is designed with a double-layer structure. The second assembly plate 330 is provided with both a first mounting groove 301 and a second mounting groove. In order to enhance the structural strength, the first assembly plate 310 can also adopt the same structural design as the second assembly plate 330.

[0034] The second mounting groove includes a guide groove 302 with its opening angled towards the ground and an assembly groove 303 with its opening angled towards the sky. The guide groove 302 and the assembly groove 303 are connected to each other. The reinforcing bar 420 moves away from the ground when it is pushed into the guide groove 302, and after reaching the end of the guide groove 302, it enters the assembly groove 303 and moves back towards the ground.

[0035] In this embodiment, the first mounting groove 301 is arranged on the first assembly plate 310 and is parallel to each other. The first mounting groove 301 is perpendicular to the setting direction of the steel column 100. Similarly, the first assembly plate 310 is also provided with the same first mounting groove 301.

[0036] The assembly groove 303 and the guide groove 302 form an inverted V-shaped structure. When the steel bar 420 reaches the highest point of the second installation groove, it falls into the assembly groove 303 and is supported by the assembly groove 303. With this structural design, the second assembly plate 330 also supports the steel bar 420. The steel bar sleeve 410 only needs to maintain the fixed engagement of the steel bar 420.

[0037] In a preferred embodiment of this invention, the inner wall of the rebar sleeve 410 is provided with threads, and both ends of the rebar 420 are provided with matching threads. The rebar sleeve 410 is nested in the end of the rebar 420 and is threadedly connected to the rebar 420.

[0038] In this embodiment, the rebar sleeve 410 is a prior art structure, and the end of the rebar 420 is pre-processed to construct a threaded structure that is compatible with the rebar sleeve 410; after the concrete is poured, the corbel 300 and the longitudinal rebar 400 will be wrapped inside the concrete beam 200. These components are placed inside the concrete beam 200 to improve the strength of the concrete beam 200 and the steel column 100.
