Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a prefabricated steel structure for construction site use. Background Technology

[0002] With the rapid development of steel structures in recent years, prefabricated steel structures have gradually come into view. Prefabricated steel structure buildings can save construction time, reduce construction costs, and reduce construction waste. Moreover, each component can be reused, making them more environmentally friendly than traditional concrete structures. Components processed uniformly in factories have high precision and ensure reliable and effective connections between components.

[0003] In traditional I-beam column connection nodes, the steel column and the beam are assembled by bolt fixing. For building structures with high strength requirements, the connection node between the steel column and the beam is subjected to large forces, but the stress area is small and the stress application points are few, which can easily lead to deformation at the connection and affect the stress performance of the connection point.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example: This example discloses a prefabricated steel structure for construction sites, such as... Figures 1-7 As shown, the present invention includes: a steel column 1 and a first steel beam 2 and a second steel beam 3 connected to adjacent sides of the steel column 1, with two of each; wherein the steel column 1, the first steel beam 2, and the second steel beam 3 are all I-beam structures, the first steel beam 2 and the second steel beam 3 are the same size, the first steel beam 2 is connected to the web surface of the steel column 1, and the second steel beam 3 is connected to the flange surface of the steel column 1; and four connectors 4 are fixedly connected to the steel column 1, the first steel beam 2, and the second steel beam 3 by bolt assemblies, respectively installed between adjacent first steel beam 2 and second steel beam 3; compared with the prior art in which the first steel beam 2 and the second steel beam 3 are independently installed on the steel column 1, this embodiment uses connectors 4 to fix the steel column 1, the first steel beam 2, and the second steel beam 3 into a whole, and the first steel beam 2 and the second steel beam 3 are also fixedly connected to each other, making the overall structure more stable.

[0027] like Figures 2-6As shown, the connector 4 has a first connecting hole 403, and the web of the steel column 1 has a first mounting hole 102 that mates with the first connecting hole 403. The first mounting hole 102 is connected to the first connecting hole 403 by a bolt assembly. The two connectors 4 on both sides of the web of the steel column 1 are fixedly connected by the same set of bolt assemblies. The connector 4 has a first connecting block 401, which is integrally formed with the connector 4. The first connecting block 401 fits and is fixedly connected to the web of the first steel beam 2. The first connecting block 401 has a second connecting hole 404, and the first steel beam 2 has a second mounting hole 201 that mates with the second connecting hole 404. The second connecting hole 404... The bolt assembly connects to the second mounting hole 201, and the two first connecting blocks 401 on both sides of the web of the first steel beam 2 are fixedly connected by the same set of bolt assemblies; the connector 4 is provided with a second connecting block 402, which is integrally formed with the connector 4, and the second connecting block 402 fits and is fixedly connected to the web of the second steel beam 3; the second connecting block 402 is provided with a third connecting hole 405, and the second steel beam 3 is provided with a third mounting hole 302 that mates with the third connecting hole 405; the third connecting hole 405 is connected to the third mounting hole 302 by a bolt assembly, and the two second connecting blocks 402 on both sides of the web of the second steel beam 3 are fixedly connected by the same set of bolt assemblies.

[0028] Furthermore, the width of the first connecting block 401 is the same as the width of the web of the first steel beam 2, and the first connecting block 401 is in contact with the flange surface of the first steel beam 2, so that the flange of the first steel beam 2 can share the force of the web and avoid excessive stress on the web leading to deformation; the width of the second connecting block 402 is the same as the width of the web of the second steel beam 3, and the second connecting block 402 is in contact with the flange surface of the second steel beam 3.

[0029] like Figure 2 and Figure 5 As shown, the connector 4 is provided with a pair of symmetrically arranged inserts 406. The inserts 406 are located between the flange of the first steel beam 2 and the flange of the steel column 1, and the surface of the inserts 406 is in contact with the surfaces of the two flanges, increasing the compactness and stability of the structure between the connector 4, the steel column 1, and the first steel beam 2. The web of the steel column 1 is provided with insertion holes 103 that mate with the inserts 406. By inserting the inserts 406 into the insertion holes 103, the number of stress points and the stress area on the steel column 1 are increased, preventing excessive stress at any one point from causing deformation.

[0030] Furthermore, the flange of the steel column 1 is provided with a limiting groove 101, and the connector 4 is provided with a slot 407 that mates with the limiting groove 101. When the connector 4 is installed on the steel column 1, it is connected to the limiting groove 101 through the slot 407, so that the flange of the steel column 1 can share the force of the web, and the flange and web of the steel column 1 can be subjected to force simultaneously, so that the force is evenly distributed and the web is prevented from deforming.

[0031] Furthermore, a limiting block 411 is fixedly connected to the second connecting block 402, and a limiting hole 301 is provided on the second steel beam 3 to cooperate with the limiting block 411. By connecting the limiting block 411 in the limiting hole 301, the stress points and stress area of ​​the second steel beam 3 are increased, and the second steel beam 3 is further stabilized.

[0032] like Figures 5-7 As shown, a fixing block 408 is fixedly connected to the connector 4, and a pair of brackets 409 are fixedly connected to the fixing block 408, respectively for supporting the bottom of the first steel beam 2 and the second steel beam 3. Each bracket 409 includes a connecting column 4091, which is fixedly connected to the fixing block 408 by an internal hex bolt. A support plate 4093 is vertically fixedly connected to one end of the connecting column 4091. The length of the support plate 4093 is between 0.3 and 0.5 m. The surface of the support plate 4093 contacts the bottom surfaces of the first steel beam 2 and the second steel beam 3, providing auxiliary support for them. Furthermore, the connector 4 has a limiting protrusion 410 on its surface, and the connecting column 4091 has a limiting groove 4092 that engages with the limiting protrusion 410. The limiting protrusion 410 connects to the limiting groove 4092, reducing the stress on the internal hex bolt and increasing the connection stability between the bracket 409 and the fixing block 408.

[0033] In this embodiment, the steel column 1, the first steel beam 2, and the second steel beam 3 are connected together by the connector 4, which increases the stability of the overall structure and increases the stress points and stress areas at the connection points between the steel beams and the steel column 1. Compared with the prior art where only the web of the steel column 1 bears the stress, in this embodiment, the web and flanges of the steel column 1, the first steel beam 2, and the second steel beam 3 all bear the stress through the connector 4, increasing the number of stress-bearing components and avoiding deformation caused by excessive stress on the web.
