Abstract
Description
Technical Field
[0001] This utility model relates to the field of building reinforcement technology, and in particular to a hinged structure for steel beams and concrete beams. Background Technology
[0002] In modern building construction, the connection between steel beams and concrete beams is a common structural form. This connection method not only fully utilizes the mechanical properties of both steel and concrete, but also improves the overall stability and load-bearing capacity of the structure.
[0003] Traditional steel beams connected to concrete beams have limited bending resistance due to the lack of supporting structure at the bottom of the steel beam after installation. Under large loads, the steel beam is prone to bending deformation, affecting the overall stability of the structure. Since the connection points between the steel beam and the concrete beam are usually concentrated in a certain area, stress concentration is likely to occur. Stress concentration will accelerate fatigue damage at the connection points and reduce the service life of the structure. Therefore, we propose a hinged steel beam-concrete beam structure. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a hinged structure for steel beams and concrete beams.
[0005] This utility model is achieved using the following technical solution: a steel beam-concrete beam hinged structure, comprising a concrete beam, wherein high-strength bolts are installed inside the concrete beam, a fixing plate is inserted into the right end of the high-strength bolts, a first nut is threaded onto the right end of the high-strength bolts, a connecting plate is fixedly connected to the right end of the fixing plate, a steel beam is provided at the rear end of the connecting plate, fastening bolts are inserted into the inner walls of both the connecting plate and the steel beam, a second nut is threaded onto the front end of the fastening bolts, and a reinforcing component is provided at the bottom of the steel beam.
[0006] The above technical solution involves installing and fixing the fixing plate with high-strength bolts and the first nut, and then installing the steel beam on the connecting plate with fastening bolts and the second nut, which strengthens the concrete beam and facilitates installation.
[0007] As a further improvement to the above solution, the reinforcement component includes a first fixing seat, a first bolt inserted into the inner wall of the first fixing seat, a reinforcement plate inserted into the surface of the first bolt, a second bolt inserted into the end of the reinforcement plate away from the first fixing seat, a second fixing seat inserted into the surface of the second bolt, and a fastening nut threadedly connected to one end of both the first bolt and the second bolt.
[0008] The above technical solution involves inserting the first bolt into the interior of the first fixing seat and the reinforcing plate, inserting the second bolt into the interior of the reinforcing plate and the second fixing seat, and locking the first and second bolts with fastening nuts to fix the reinforcing plate, which facilitates subsequent disassembly and maintenance.
[0009] As a further improvement to the above solution, the left end of the first fixing seat is fixedly connected to the right end of the fixing plate.
[0010] With the above technical solution, the first fixing seat is welded to the fixing plate, which facilitates the subsequent installation of the reinforcing plate.
[0011] As a further improvement to the above solution, two reinforcing plates are provided, and the two reinforcing plates are symmetrically distributed with the first fixing seat as the center.
[0012] The above technical solution uses two reinforcing plates to support the bottom of the steel beam, which enables the structure to remain stable under large loads and is less prone to breakage or detachment. This effectively improves the bending resistance of the steel beam. Under load, the reinforcing plates can share part of the bending moment, reduce the burden on the steel beam, and effectively extend the service life of the structure. The number and position of the reinforcing plates can be adjusted according to the actual engineering needs.
[0013] As a further improvement to the above solution, the top of the second fixing seat is fixedly connected to the bottom of the steel beam.
[0014] With the above technical solution, the second fixing seat is welded to the bottom of the steel beam, which facilitates the subsequent installation of the reinforcing plate.
[0015] As a further improvement to the above solution, one end of the first bolt passes through the first fixing seat.
[0016] As a further improvement to the above solution, one end of the second bolt passes through the second fixing seat.
[0017] With the above technical solution, the second bolt extends outward through the second fixing seat, which facilitates the installation of the fastening bolt and makes the bolt outside, which is convenient for subsequent disassembly.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This utility model, by setting up a reinforcement component, specifically by inserting a first bolt into the interior of the first fixing seat and the reinforcement plate, and inserting a second bolt into the interior of the reinforcement plate and the second fixing seat, and locking the first and second bolts with fastening nuts, fixes the reinforcement plate.

This effectively improves the bending resistance of the steel beam. Under load, the reinforcement plates can share part of the bending moment, reducing the burden on the steel beam and effectively extending the service life of the structure.
[0020] This utility model, by setting up a reinforcement component, specifically by removing the fastening nut and taking out the first and second bolts from the first fixing seat and the second bolt, can remove the reinforcement plate, which facilitates the subsequent disassembly and replacement of the reinforcement plate and improves the convenience of subsequent maintenance.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example
[0029] Please combine Figure 1-5The steel-concrete beam hinged structure of this embodiment includes a concrete beam 1. High-strength bolts 2 are installed inside the concrete beam 1. A fixing plate 3 is inserted into the right end of the high-strength bolts 2. A first nut 4 is threadedly connected to the right end of the high-strength bolts 2. A connecting plate 5 is fixedly connected to the right end of the fixing plate 3. A steel beam 7 is provided at the rear end of the connecting plate 5. Fastening bolts 6 are inserted into the inner walls of both the connecting plate 5 and the steel beam 7. A second nut 8 is threadedly connected to the front end of the fastening bolts 6. A reinforcing component 9 is provided at the bottom of the steel beam 7. The fixing plate 3 is installed and fixed by the high-strength bolts 2 and the first nut 4. Then, the steel beam 7 is installed on the connecting plate 5 by the fastening bolts 6 and the second nut 8.
[0030] The reinforcement component 9 includes a first fixing seat 901, a first bolt 902 inserted into the inner wall of the first fixing seat 901, a reinforcement plate 903 inserted into the surface of the first bolt 902, a second bolt 905 inserted into the end of the reinforcement plate 903 away from the first fixing seat 901, a second fixing seat 904 inserted into the surface of the second bolt 905, and a fastening nut 906 threadedly connected to one end of both the first bolt 902 and the second bolt 905. The steel beam 7 is installed on the connecting plate 5 by fastening the bolt 6 and the second nut 8. The first bolt 902 is inserted into the interior of the first fixing seat 901 and the reinforcement plate 903, and the second bolt 905 is inserted into the interior of the reinforcement plate 903 and the second fixing seat 904. The first bolt 902 and the second bolt 905 are locked by fastening the nut 906, thereby fixing the reinforcement plate 903 and facilitating subsequent disassembly and maintenance.
[0031] The left end of the first fixed seat 901 is fixedly connected to the right end of the fixed plate 3.
[0032] There are two reinforcing plates 903, which are symmetrically distributed around the first fixed seat 901. The bottom of the steel beam 7 is supported by the two reinforcing plates 903, so that the structure can remain stable when subjected to large loads and is not prone to breakage or fall off. This can effectively improve the bending resistance of the steel beam 7. Under load, the reinforcing plates 903 can share part of the bending moment, reduce the burden on the steel beam 7, and effectively extend the service life of the structure.
[0033] The top of the second fixing seat 904 is fixedly connected to the bottom of the steel beam 7.
[0034] One end of the first bolt 902 passes through the first fixing seat 901.
[0035] One end of the second bolt 905 passes through the second fixing seat 904.
[0036] The implementation principle of the steel-concrete beam hinged structure in this embodiment is as follows: During use, the fixing plate 3 is installed and fixed using high-strength bolts 2 and the first nut 4. Then, the steel beam 7 is installed on the connecting plate 5 using fastening bolts 6 and the second nut 8. Finally, the first bolt 902 is inserted into the first fixing seat 901 and the reinforcing plate 903, and the second bolt 905 is inserted into the reinforcing plate 903 and the second fixing seat 904. The first bolt 902 and the second bolt 905 are locked using fastening nuts 906, thus fixing the reinforcing plate 903. The bottom of the steel beam 7 is then secured by the two reinforcing plates 903. The reinforcement plate 903 provides support, enabling the structure to remain stable under heavy loads and preventing breakage or detachment. This effectively improves the bending resistance of the steel beam 7. Under load, the reinforcement plate 903 can share some of the bending moment, reducing the burden on the steel beam 7 and effectively extending the service life of the structure. When the reinforcement plate 903 needs to be replaced, it can be removed by unfastening the fastening nut 906 and taking out the first bolt 902 and the second bolt 905 from the first fixing seat 901 and the second bolt 905. This facilitates the subsequent disassembly and replacement of the reinforcement plate 903 and improves the convenience of subsequent maintenance.
