[0002] Prefabricated steel structure buildings originated in the 19th century. At that time, due to the development of industrialization, people began to try to use prefabricated components for assembly and splicing in buildings to realize the industrial production of buildings. In China, with the rapid development of the construction industry and people's attention to environmental protection, prefabricated steel structure buildings have gradually been promoted and applied. In recent years, the state has introduced a series of policies to encourage and support the development of prefabricated steel structure buildings. The focus of prefabricated steel structure is the connection node. With the continuous advancement of steel structure design technology and manufacturing technology, the application scope of prefabricated steel structure nodes is becoming more and more extensive, which can meet the needs of different types of buildings. However, prefabricated steel structure nodes need to overcome difficulties and challenges in many aspects in application, including design, production, transportation, installation and other links. When promoting and applying prefabricated steel structure nodes, their economy and feasibility need to be considered.

Through the set mounting connection structure, the fixing frame is installed by fixing screws, and it can be selected whether to assemble and use the mounting connection structure according to actual conditions. At the same time, the mounting connection structure is provided with a clamping plate and a locking assembly, which can ensure the stability after connection with the second steel structure, and ensure the connection effect of the entire node component. The use of a reinforcing assembly and a support clamping block can play a clamping role on the mounting connection structure, and when used in conjunction with the buckle, the stability of the mounting connection structure and the second steel structure after installation can be further ensured.

[0004] However, this structure also has some problems.

In addition, this node structure can only be connected in one direction, making it difficult to connect in the other direction, and the feasibility is relatively low. Utility Model Content

[0040] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] The present application relates to a steel beam-column connection node structure. The steel beam-column node structure of the present application is a connection node structure between a steel beam and a steel column. The steel column of the present application is a vertical square steel tube, such as Figure 4 As shown, the steel beam is an I-shaped steel structure, such as Figure 5 As shown, the steel beams are arranged in the horizontal direction, and the ends of the steel beams are fixed to the sides of the steel columns. The four sides of the steel columns are all provided with steel beams. In actual application, it is not limited to this assembly form, and the appropriate number of steel beams can be selected for arrangement according to actual needs. This application uses standard connectors to fix the steel beams to the sides of the steel columns for installation. The connectors are prefabricated in the factory and fixed to the steel beams and steel columns through bolt connection structures. The overall assembly is simple, the installation is convenient, and the structure has good stress resistance.

[0042] Specifically, the steel beam-column connection node structure of the present application includes a steel column 1 and steel beams 2 disposed on both sides of the steel column 1 in the horizontal direction and in the vertical direction. The steel column 1 is a square steel pipe pile arranged vertically, and the steel beam 2 is an I-shaped horizontal beam with a web arranged vertically. In order to fix the steel beam 2 to the side of the steel column 1, the present application also includes flange connectors and web connectors, such as Figure 1 As shown, the flange connectors are disposed on the upper and lower sides of the steel beam 2, and are used to connect the upper flange and the lower flange of the steel beam 2 to the side of the steel column 1. The flange connectors include a first clamping structure bolted to the flange of the steel beam 2 and a first connecting portion 3 bolted to the steel column 1. The first clamping structure is clamped and fixed to the upper and lower sides of the flange by a bolt structure.

[0043] The web connector is located on one side of the web of the steel beam 2 and is used to fix the web of the steel beam 2 to the side of the steel column 1. The web connector includes a second clamping structure bolted to the web of the steel beam 2 and a second connecting portion 4 bolted to the steel column 1. The second clamping structure is clamped and fixed to the horizontal sides of the web by a bolt structure.

[0044] The first connection part 3 and the second connection part 4 of the present application are structures connected to the side of the steel column 1. Figures 1 to 3 As shown in the figure, it is a plate-like structure that fits tightly with the side of the steel column 1. In practical application, it is not limited to this structure, and can be other fixed structures as long as it can be conveniently fixed to the side of the steel column 1 through a bolt structure. A first clamping structure is provided on the first connecting part 3, and the first clamping structure and the first connecting part 3 form a T-shaped member structure. A second clamping structure is provided on the second connecting part 4, and the second clamping structure and the second connecting part 4 form a T-shaped member structure. The T-shaped member structure is well stressed and can effectively bear the shear force and bending moment at the node.

[0045] The first clamping structure and the second clamping structure clamp and fix the flange and the web respectively, that is, the contact area between the flange and the web and the flange connector and the web connector is greatly improved, the overall connection structure is more stable and firm, and the connection node structure formed by the steel beam 2 being fixed on the steel column 1 based on the flange connector and the web connector is clearly stressed. At the same time, this clamping structure also greatly facilitates the installation of the steel beam 2 and the steel column 1.

[0046] During actual assembly, first install the flange connector below the steel beam 2, pass the bolts through the screw holes between the first connection part 3 and the side of the steel column 1, tighten and fix the first connection part 3 to the side of the steel column 1, and proceed in sequence until the flange connectors on the four sides of the steel column 1 are installed; install the web connector on the side of the steel column 1, pass the bolts through the screw holes between the second connection part 4 and the side of the steel column 1, and fix the second connection part 4 to the side of the steel column 1, and proceed in sequence until the web connectors on the four sides of the steel column 1 are fixed and connected; install the flange connector above the steel beam 2 on the side of the steel column 1 according to the above process, pass the bolts through the screw holes between the first connection part 3 and the side of the steel column 1, tighten the first connection part 3 Tightly fix it to the side of the steel column 1, and proceed in sequence until the flange connectors on the four sides of the steel column 1 are installed; install the steel beam 2, move the steel beam 2 to the top of the flange connector in the vertical arrangement of the web, insert the lower flange of the steel beam 2 into the first clamping structure below, and fix the lower flange to the first clamping structure below by the bolt structure, insert the web of the steel beam 2 into the second clamping structure, and fix the web to the second clamping structure by the bolt structure, insert the upper flange of the steel beam 2 into the first clamping structure above, and fix the upper flange to the first clamping structure above by the bolt structure, and proceed in sequence until the four steel beams 2 are fixedly connected to the steel column 1.

[0047] The present application provides multiple screw holes on the side of the steel column 1, and the installation positions of the screw holes correspond to the steel beam 2, or in other words, correspond one-to-one with the installation positions of the first connection part 3 and the second connection part 4. Therefore, it is only necessary to install the corresponding first connection part 3 or the second connection part 4 according to the positions of the screw holes. Finally, a structure for connecting the steel beam 2 can be formed on the side of the steel column 1, and the steel beam 2 can be conveniently fixed to the side of the steel column 1. The overall installation is very simple.

[0048] In some embodiments of the present application, the first clamping structure is optimized. Specifically, Figure 1 and 2 As shown, the first clamping structure includes two first clamping plates 5, which are vertically fixed on the first connecting part 3 to form a T-shaped component with the first connecting part 3, and the two first clamping plates 5 are arranged at intervals and placed on the upper and lower sides of the flange. The first clamping plate 5 is provided with through holes that pass through the plate body and correspond to the screw holes on the flange.

[0049] The first clamping structure is actually to clamp the flange by two first clamping plates 5 arranged at intervals along the vertical direction, and the upper and lower end surfaces of the flange are attached to the first clamping plates 5 on both sides, and then bolts are passed through the first clamping plates 5 and the flange, and the flange can be fixed in the two first clamping plates 5 by tightening the bolts. This connection method, on the one hand, makes it extremely convenient to fix the flange, and it only needs to extend the flange into the two first clamping plates 5. On the other hand, both sides of the flange are fixed and supported by the first clamping plates 5, and the stability of the flange is greatly guaranteed. In actual use, the force acting on the flange can be quickly transmitted to the steel column 1 through the first clamping plates 5 on both sides, and the force structure is very clear.

[0050] There are two ways to fix the flange and the flange connector in this embodiment. One is as follows: Figure 1 and 2 As shown, each steel beam 2 is fixedly connected to the steel column 1 through two sets of flange connectors. The two sets of flange connectors located on the same side of the steel column 1 are vertically spaced and correspond to the upper flange and the lower flange of the steel beam 2 respectively. A slot for the web to pass through is provided on the first clamping plate 5 close to the web in the flange connector.

[0051] That is, each steel beam 2 is fixedly connected to the side of the steel column 1 through two sets of upper and lower flange connectors, the two sets of flange connectors are respectively fixed to the upper and lower flanges of the steel beam 2, the width of the first clamping plate 5 in the flange connector is equivalent to the width of the flange, and the first clamping plate 5 fits tightly with the flange. In order to facilitate the fixation of the first clamping plate 5 to the flange, in this installation form, two sets of through holes are opened on the first clamping plate 5, the two sets of through holes are respectively placed on both sides of the web, and each set includes a plurality of through holes arranged at intervals along the length direction of the web.

[0052] In fact, the two groups of through holes are symmetrically arranged with the web as the center, and the web just coincides with the center line of the first clamping plate 5. This ensures that after the first clamping plate and the flange are tightened by bolts, the force centers of the first clamping plate 5, the flange and the web coincide, avoiding bending moment and greatly improving the stability of the entire node structure.

[0053] Another arrangement structure is that each flange is fixedly connected to the steel column 1 through two groups of flange connectors, and the two groups of flange connectors fixed to the same flange are placed on both sides of the web. That is, for the fixation of each flange, two groups of flange connectors arranged in parallel are used for assembly, the first clamping plates 5 of the two groups of flange connectors are arranged in parallel in the horizontal direction and are at the same horizontal height, the first clamping plates 5 of the two groups of flange connectors are placed on both sides of the web, and the two groups of first clamping structures form a limiting structure for limiting the web, and then the bolts pass through the first clamping plates 5 and the flanges in turn to fix the flanges on the first clamping plates 5. Such an assembly structure requires four groups of flange connectors for assembly of a steel beam 2, which consumes more prefabricated components, but at the same time, this assembly mode is less restricted, suitable for the installation of steel beams 2 of various specifications and sizes, and the installation and assembly method is very simple.

[0054] In addition, when assembling the steel beam 2 to the flange connector, the end of the flange abuts against the first connection part 3. That is, there is a direct connection relationship between the flange and the first connection part 3, and the force on the flange can be directly transmitted to the steel column 1 through the first connection part 3, which greatly improves the force transmission efficiency. At the same time, the direct contact method improves the stability of the installation of the steel beam 2, and the first connection part 3 and the steel column 1 provide a supporting force for the steel beam 2.

[0055] In some other embodiments of the present application, the second clamping structure is optimized. Figure 1 and 3 As shown, the second clamping structure of this embodiment includes two second clamping plates 6, which are vertically fixed on the second connecting part 4 to form a T-shaped component with the second connecting part 4, and the two second clamping plates 6 are arranged at intervals and placed on both sides of the web. The second clamping plates 6 are provided with through holes that pass through the plate body and correspond to the screw holes on the web.

[0056] The second clamping structure is the same as the first clamping structure, and includes two second clamping plates 6, which are vertically fixed on the second connecting portion 4 to form a T-shaped member. The web connector of this embodiment is also a standard component prefabricated in the factory. The two second clamping plates 6 form a clamping structure for clamping the web. The two sides of the web are tightly fitted to the two second clamping plates 6 and are fixedly connected by bolts. This assembly method improves the firmness of the web installation, making the installation of the web and the web connector more firm and stable, and the force bearing performance is also greatly improved.

[0057] During assembly, the web connector prefabricated in the factory is first installed on the side of the steel column 1. Specifically, the second connecting part 4 is first fitted to the side of the steel column 1, and then bolts are driven into the screw holes on the second connecting part 4 and the side of the steel column 1 to fix the second connecting part 4 to the side of the steel column 1; then the web of the steel beam 2 is inserted between the two second clamping plates 6, the screw holes on the web are aligned with the through holes on the second clamping plates 6, bolts are driven into the through holes of the second clamping plates 6 and the web, and the web is fixed to the second clamping plates 6, completing the installation and assembly of the web and the web connector.

[0058] At the same time, in order to improve the stability of the web installation, when the web of this embodiment is installed, the end of the web abuts against the second connection part 4. Such an assembly structure makes the connection between the steel beam 2 and the steel column 1 more secure. The web is directly in contact with the second connection part 4, and the force of the web can be directly transmitted to the steel column 1 through the second connection part 4. At the same time, the steel column 1 and the second connection part 4 can effectively support the web, so that the stability of the entire node structure is greatly improved.

[0059] In a further embodiment of the present application, the positional relationship between the flange connector and the web connector is optimized. Specifically, there is a gap between the upper and lower ends of the second connector 4 and the upper and lower first connectors 3. That is, the flange connector and the web connector on the same side of the steel column 1 are independent of each other, and there is no direct connection between the second connector 4 and the upper and lower first connectors 3, so there is no interference between them.

[0060] During actual assembly, flange connectors and web connectors are prefabricated in the factory. The flange connector includes a first connection part 3 and two first clamping plates 5. The two first clamping plates 5 are vertically fixed at the middle position of the first connection part 3 to form a T-shaped member with the first connection part 3. The web connector includes a second connection part 4 and two second clamping plates 6. The two second clamping plates 6 are vertically fixed at the middle position of the second connection part 4 to form a T-shaped member with the second connection part 4. The flange connector and web connector are installed on the side of the steel column 1. The flange connector is divided into two groups, corresponding to the upper flange and the lower flange of the steel beam 2 respectively. The first connection part 3 of the flange connector is fitted with the side of the steel column 1 so that the through hole on the first connection part 3 is aligned with the screw hole on the steel column 1. Bolts are inserted into the first connection part 3 and the steel column 1 and tightened to fix the first connection part 3 to the side of the steel column 1. The flange connectors are installed in sequence in this way until the first connection parts 3 of all flange connectors are fixed. Fix it to the set position on the steel column 1; fit the second connection part 4 of the web connector to the side of the steel column 1, align the through holes on the second connection part 4 with the corresponding screw holes on the side of the steel column 1 one by one, penetrate the bolts 4 and the side of the steel column 1 and tighten them, fix the second connection part 4 to the side of the steel column 1, and proceed in sequence until the web connector on the side of the steel column 1 is installed; install the steel beam 2, insert the flange of the steel beam 2 between the first clamping plates 5 of the flange connector, insert the upper and lower flanges between the corresponding two first clamping plates 5, and insert the web between the corresponding two second clamping plates 6, drive bolts into the through holes aligned with the first clamping plate 5 and the flanges, and drive bolts into the through holes aligned with the second clamping plate 6 and the web, fix the flange and the web on the first clamping plate 5 and the second clamping plate 6 respectively, and complete the installation of the steel beam 2, and proceed in sequence until all the steel beams 2 are assembled and the assembly process of the steel beam-column connection node is completed.
