Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction anchoring connection tool. Background Technology

[0002] In modern construction engineering, reinforced concrete structures are widely used in high-rise buildings, bridges, tunnels, and underground engineering. Effective anchorage of the reinforcing bars is crucial to ensuring the integrity and load-bearing capacity of the structure. Traditional rebar anchorage methods mainly rely on end hooks (such as 90° or 180° hooks) or extending the anchorage length to achieve bond anchorage. However, as building structures develop towards higher strength, higher durability, and prefabrication, traditional anchorage methods have gradually revealed many problems: on the one hand, in high-strength concrete or high-stress areas, the bond performance between the reinforcing bars and concrete is difficult to meet design requirements; on the other hand, areas with densely packed reinforcing bars (such as beam-column joints and foundation caps) often lack sufficient straight anchorage length or hook operation space due to space constraints, leading to construction difficulties and challenges in quality control.

[0003] To address the aforementioned issues, rebar anchor plates (also known as mechanical anchor plates or end anchor plates) have been introduced into engineering practice as an efficient and reliable mechanical anchoring device. This technology involves welding or threading a steel plate of a specific size and strength to the end of the rebar. The tensile force of the rebar is transferred through the bearing capacity between the steel plate and the concrete, thereby significantly shortening the required anchorage length (typically by 30% to 60%) and avoiding processing errors and stress concentration caused by rebar bending.

[0004] However, in actual construction, the ends of the reinforcing bars are directly welded to the upper and lower end faces of the perforated anchor plate. This not only results in stress concentration and poor durability, but also makes the weld prone to shear failure or tearing under tensile force, rather than the reinforcing bar breaking, thus affecting the performance. Utility Model Content

[0005] This utility model provides a building construction anchoring connection fixture. By setting a bent rod or extension rod with a second fixing ring at the end of the reinforcing bar, it can increase the connection strength with the anchoring steel plate, improve the tensile strength, and reduce shear failure or tearing. It solves the problems of stress concentration, poor durability, and easy shear failure or tearing mentioned in the background art.

[0006] This utility model provides the following technical solution: An anchoring connection tool for building construction includes an anchoring steel plate with a central hole and multiple reinforcing bars. The anchoring steel plate has multiple through holes at both ends. The reinforcing bars are fixedly connected in the corresponding through holes. A connector is fixedly connected to one end of the reinforcing bar that passes through the through hole, and a hook is fixedly connected to the other end of the reinforcing bar.

[0007] As a preferred embodiment of the present invention, it further includes a first fixing ring fixedly connected to the reinforcing bars. The first fixing ring has a closed ring structure and is sleeved on the outside of multiple reinforcing bars.

[0008] As a preferred embodiment of this utility model, the connector includes a bent rod fixedly connected to one end of the reinforcing bar through the through hole, the end of the bent rod away from the reinforcing bar abutting against the bottom of the anchoring steel plate, and the bent rod extending toward the center hole of the anchoring steel plate.

[0009] As a preferred embodiment of this utility model, the angle between the axis of the bent rod and the axis of the reinforcing bar is 70°-90°.

[0010] As a preferred embodiment of this utility model, the connector includes a second fixing ring, an extension rod is fixedly connected to one end of the reinforcing bar that passes through the through hole, the second fixing ring is fixedly connected to the outside of the extension rod, and the top of the second fixing ring abuts against the bottom of the anchoring steel plate.

[0011] As a preferred embodiment of this utility model, the thickness of the anchoring steel plate ranges from 6 to 20 mm.

[0012] Compared with the prior art, this utility model provides a building construction anchoring connection fixture, which has the following beneficial effects: 1. In this construction anchoring connection fixture, by fixing a bent rod extending towards the middle of the anchoring steel plate at the bottom of the reinforcing bar, the tensile strength of the reinforcing bar can be improved, the occurrence of shear failure or tearing can be reduced, and the durability can be improved.

[0013] 2. In this construction anchoring connection fixture, by welding the second fixing ring to the bottom of multiple reinforcing bars to make them a single unit, and then abutting the bottom of the anchoring steel plate with the second fixing ring or welding the second fixing ring to the bottom plate of the anchoring steel plate, it is possible not only to significantly increase the connection strength between reinforcing bars, reduce shear failure or tearing, and improve durability, but also to avoid stress concentration.

[0014] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model fixes the reinforcing bar to the anchoring steel plate, and sets a bending rod or a second fixing ring at the bottom of the reinforcing bar, which can increase the connection strength between the reinforcing bar and the anchoring steel plate, reduce the occurrence of shear failure or tearing, and the single-sided welding can reduce stress concentration and improve durability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Reference Figures 1-3 An anchoring connection fixture for building construction includes an anchoring steel plate 1 with a central hole. The thickness of the anchoring steel plate 1 ranges from 6 to 20 mm, and the thickness should not be less than 0.3 times the diameter of the reinforcing bar 2. Of course, the minimum thickness should not be less than 6 mm, and preferably 10 mm. It also includes multiple reinforcing bars 2, with two to eight bars, preferably six. Taking a diameter of 20 mm as an example, the anchoring steel plate 1 has multiple through holes 101 at both ends, preferably six. The reinforcing bars 2 are respectively fixedly connected in the corresponding through holes 101. The upper end face of the through hole 101 is fixedly connected to the reinforcing bar 2 by welding. A connector is fixedly connected to one end of the reinforcing bar 2 that passes through the through hole 101, and a hook 201 is fixedly connected to the other end of the reinforcing bar 2 to facilitate the connection between external objects and the reinforcing bar 2. In use, by fixing the reinforcing bar 2 to the anchoring steel plate 1, and setting the connector at the bottom of the reinforcing bar 2, the connection strength between the reinforcing bar 2 and the anchoring steel plate 1 can be increased, reducing the occurrence of shear failure or tearing. Moreover, single-sided welding can reduce stress concentration and improve durability.

[0020] It also includes a first fixing ring 3 fixedly connected to the reinforcing bar 2. Here, it is preferred that the first fixing ring 3 is fixedly connected to the reinforcing bar 2 by welding. The first fixing ring 3 has a closed ring structure. The first fixing ring 3 is a rectangular closed ring formed by bending a round bar. The diameter of the first fixing ring 3 is 0.5-1mm, preferably 0.5mm. The first fixing ring 3 is sleeved on the outside of the multiple reinforcing bars 2 and in the middle of the multiple reinforcing bars 2. In use, the outer walls of the multiple reinforcing bars 2 are fixed by the first fixing ring 3, which can make the multiple reinforcing bars 2 into one, thereby increasing the overall strength and improving the performance.

[0021] Here, the connector includes a bent rod 202 fixedly connected to one end of the reinforcing bar 2 passing through the through hole 101. The end of the bent rod 202 away from the reinforcing bar 2 abuts against the bottom of the anchoring steel plate 1. That is, when the reinforcing bar 2 is fixed to the upper end face of the through hole 101 by welding, the end of the bent rod 202 is first abutted against the bottom of the anchoring steel plate 1, and then the reinforcing bar 2 is fixed to the upper end face of the through hole 101 by welding. In addition, in order to improve the torsional resistance of the reinforcing bar 2, the end face of the bent rod 202 can also be fixed to the bottom of the anchoring steel plate 1 by welding, and the bent rod 202 extends towards the center hole of the anchoring steel plate 1. The angle between the axis of the bent rod 202 and the axis of the reinforcing bar 2 is 70°-90°. Here, 75° is taken as an example. By setting the minimum angle to 70°, the bending degree of the bent rod 202 can be reduced, the phenomenon of breakage can be reduced, and the service effect can be improved.

[0022] Example 2: Reference Figure 4 Similar to Embodiment 1, but with an extension of the connector, the connector includes a second fixing ring 301. The second fixing ring 301 is also a closed ring with a rectangular structure formed by bending a round bar. The diameter of the first fixing ring 3 is 0.5-1mm, preferably 0.5mm. One end of the reinforcing bar 2 passing through the through hole 101 is fixedly connected to an extension rod. The second fixing ring 301 is fixedly connected to the outside of the extension rod, and the top of the second fixing ring 301 abuts against the bottom of the anchoring steel plate 1. In use, by welding the second fixing ring 301 to the bottom of multiple reinforcing bars 2 to form a single unit, and then abutting the second fixing ring 301 against the bottom of the anchoring steel plate 1 or welding the second fixing ring 301 to the bottom plate of the anchoring steel plate 1, the connection strength between the reinforcing bars 2 can be significantly increased, reducing shear failure or tearing and improving durability. Furthermore, stress concentration can be avoided.
