[0002] Load-bearing beams are widely used in buildings to improve the local structural strength of buildings. Load-bearing beams can be made of concrete, steel or wood. The specific choice should be considered comprehensively based on factors such as the use environment, load-bearing conditions and budget.

[0003] Concrete load-bearing beams are one of the most widely used load-bearing beams at present. They have the advantages of strong bearing capacity, good durability, and fire resistance. Concrete load-bearing beams have moderate material cost and simple construction, and are suitable for various building structures, especially large-span structures.

[0004] Wood load-bearing beams have low cost, light weight, and are easy to construct. They are especially suitable for roofs and beams with special requirements for building appearance. However, their bearing capacity is relatively small, and they are not suitable for some larger load-bearing projects.

[0032] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0033] Embodiment 1:

[0034] This embodiment introduces a specific structure of a high-strength assembled steel load-bearing beam structure. Figure 1-Figure 4 As shown, it includes two steel load-bearing beam bodies 1 and two fixed joints 2 combined and connected between the two steel load-bearing beam bodies 1, the fixed joints 2 include an L-shaped plate 201, the inner wall of one side of the L-shaped plate 201 is integrally formed with a support column 202, and the inner sides of the support column 202 are both provided with a limit rod 4;

[0035] The two fixed joints 2 are respectively located at the top of one side and the bottom of the other side of the steel load-bearing beam body 1. In order to connect and fix the two fixed joints 2, as shown in FIG. Figure 1 and Figure 2 As shown, a plurality of first threaded rods 3 are processed on the top of the support column 202. By passing the plurality of first threaded rods 3 on one fixing joint 2 through the inside of another fixing joint 2, after a nut is connected at one end of the first threaded rod 3, the two fixing joints 2 can be connected and fixed, so that the two fixing joints 2 are supported between the two steel load-bearing beam bodies 1, and the lateral shear force after the two steel load-bearing beam bodies 1 are connected can be resisted;

[0036] At the same time, when the two fixing joints 2 are combined and fixed between the two steel load-bearing beam bodies 1, the inner surface of the L-shaped plate 201 is in contact with the surface of the steel load-bearing beam body 1, and the support column 202 is inserted into the side of the two steel load-bearing beam bodies 1 from one side, so that the support column 202 forms a support between the top and the bottom of one side of the steel load-bearing beam body 1, which can resist the longitudinal shear force at the connection point of the two steel load-bearing beam bodies 1;

[0037] Secondly, in order to improve the connection stability and tightness between the fixed joint 2 and the steel load-bearing beam body 1, as Figure 1 and Figure 2 As shown, a limit hook plate 203 is integrally formed on the bottom surface of one side of the L-shaped plate 201. By inserting two steel load-bearing beam bodies 1 between the two ends of the fixing joint 2 from both sides, the limit hook plate 203 is supported on one side of the steel load-bearing beam body 1, and the inner wall of the other side of the L-shaped plate 201 is supported on the other side of the steel load-bearing beam body 1, so that the fixing joint 2 can be prevented from being separated from the outside of the steel load-bearing beam body 1, and after a nut is connected to one end of the first threaded rod 3, the steel load-bearing beam body 1 and the fixing joint 2 can be connected and fixed;

[0038] Furthermore, in order to prevent the two steel load-bearing beam bodies 1 from moving between the two fixed joints 2 after the two fixed joints 2 are fixed, Figure 3 As shown, the two limit rods 4 pass through the inside of the support column 202 on a fixed joint 2, and are respectively inserted into the inside of the support column 202 on the other fixed joint 2 through one end of the two steel load-bearing beam bodies 1. By allowing the two limit rods 4 to pass through the inside of the two fixed joints 2 at the same time and pass through the inside of the two steel load-bearing beam bodies 1 respectively, the fixed joints 2 and the steel load-bearing beam bodies 1 can be used to cooperate so that one end of the two steel load-bearing beam bodies 1 can be connected.

[0039] By adopting the above technical solution:

[0040] The above design connects the two fixed joints 2 in an opposite combination up and down, and allows the first threaded rod 3 carried by the support column 202 on one fixed joint 2 to pass through the inside of the limit hook plate 203 on the other fixed joint 2, and fixes the two fixed joints 2 by connecting nuts. After the two steel load-bearing beam bodies 1 are inserted between the two ends of the fixed joints 2 from both sides, the two limit rods 4 pass through the inside of the support column 202 on one fixed joint 2, and are pinned to one end of the two steel load-bearing beam bodies 1 respectively, and then pass through the inside of the support column 202 on the other fixed joint 2 at the same time, so as to limit the two steel load-bearing beam bodies 1 from moving away from each other.

[0041] At this time, with the help of the support column 202 supporting the top and bottom of one side of the steel load-bearing beam body 1, the two fixed joints 2 are combined and sleeved on the outside of the connection point of the two steel load-bearing beam bodies 1, which is beneficial to resist the lateral and longitudinal shear forces of the two steel load-bearing beam bodies 1 during operation, and ensure the structural strength of the connection point of the two steel load-bearing beam bodies 1 and the connection stability of the two steel load-bearing beam bodies 1.

[0042] Embodiment 2:

[0043] Based on Example 1, this example introduces the specific structure of the limit rod 4. The limit rod 4 includes a round rod 401. Both ends of the round rod 401 are processed with a truncated cone 402. One end of the truncated cone 402 is processed with a second threaded rod 403.

[0044] Among them, by pinning a round rod 401 between two support columns 202 and a steel load-bearing beam body 1 on two fixed joints 2, after a nut is connected to one end of the second threaded rod 403, the round rod 401 can be restricted from withdrawing from the inside of the support column 202 by means of the nut limiter;

[0045] At the same time, in order to facilitate the pinning of the round rod 401 between the two fixed joints 2 and a steel load-bearing beam body 1, as shown in FIG. Figure 4As shown, by setting the cone 402 as a guide member with an isosceles trapezoidal cross-section, and ensuring that the diameter of the end of the cone 402 connected to the second threaded rod 403 is smaller than the diameter of the end connected to the round rod 401, when the limiting rod 4 is installed to the inside of the steel load-bearing beam body 1 and the fixed joint 2, the round rod 401 can be more easily pinned between the fixed joint 2 and the steel load-bearing beam body 1 with the help of the guidance of the cone 402.

[0046] By adopting the above technical solution:

[0047] The above-mentioned design arranges the limit rod 4 to be composed of a central round rod 401, a truncated cone 402 with an isosceles trapezoidal cross-section and two second threaded rods 403. When the limit rod 4 is installed inside the steel load-bearing beam body 1 and the fixed joint 2, the round rod 401 can be more easily pinned between the fixed joint 2 and the steel load-bearing beam body 1 with the guidance of the truncated cone 402, and will not be affected by the hole position deviation on the steel load-bearing beam body 1 and the fixed joint 2.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
