Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a prefabricated steel beam hinged joint structure, which is applicable to beam-priority structural systems. Background Technology

[0002] Currently, there are basically two types of traditional prefabricated steel beam hinge joints: One method involves welding stiffening plates onto the main beam in the factory and then connecting them on-site using bolts. The drawback of this method is that the standardization of steel beam fabrication in the factory is not high, and there are many different types of steel beams on-site, which is not conducive to the standardized preparation of components and on-site installation. Another type of connection node uses a separate assembly method, where the main and secondary beams are connected together on site using bolts and separate connectors. The drawback of this type of connection node is that although the steel beams can be standardized in preparation, there are too many loose parts on site, which is not conducive to the on-site assembly of components and increases the complexity of the steel structure construction process. At the same time, in the beam-priority structure system, due to the large number of loose parts, the connection node structure increases, the number of bolts increases, and the material cost increases. In addition, because the cumulative allowable error of the node increases, it is not conducive to the precision control of the overall structure installation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model designs an assembled steel beam hinged node structure.

[0004] The present invention adopts the following technical solution: A prefabricated steel beam hinged joint structure includes a main beam and a secondary beam, both of which are H-shaped steel beams, including a web and flanges fixedly connected to the upper and lower sides of the web. The web and flanges of the main beam and secondary beam are provided with multiple sets of connection holes along the axial direction according to a standardized module setting. Connection ends are respectively provided at both ends of the secondary beam. A web connecting plate is fixedly installed at the end of the web of the connection end. Grooves are respectively provided on the upper and lower sides of the web of the connection end, and flange connecting plates are fixedly installed in the grooves. The web connecting plate and flange connecting plate are provided with mounting holes corresponding to each set of connection holes.

[0005] Preferably, the connecting hole and mounting hole are standard bolt holes, and the connection is fixed by standard bolts and standard nuts.

[0006] Preferably, the depth of the groove matches the thickness of the flange connecting plate.

[0007] Preferably, the web plate connecting plate is fixedly connected to the end of the web plate at the connecting end by welding, and the flange connecting plate is fixedly connected to the grooves on the upper and lower sides of the web plate by welding.

[0008] Preferably, the web and flanges have multiple sets of connecting holes with a standardized module of 100mm or N*100mm.

[0009] This invention, under the background of intelligent construction technology, realizes green prefabricated building components, enabling industrialized and standardized preparation and simplified on-site construction. It employs integrated steel beams with hinged joints, eliminating the need to consider the different installation positions of secondary beams on the main beams at the factory; while the welded stiffening connecting plates only require standardized modular openings on the main beams. This allows for standardized preparation of structural beams, only requiring differentiation based on steel beam length, simplifying joints, and standardizing factory production. On-site installation no longer relies on numbered steel beams; simply install according to the required length, making installation more convenient.

[0010] In beam-priority structural systems, when the main structure uses hinged connections, using integrated hinged connection nodes can effectively optimize the cumulative error of connections between steel structural components, increase the constraint between components, and help ensure the accuracy of component installation; it also optimizes and reduces the number of loose parts and node components installed on site.

[0011] The beneficial effects of this utility model are: (1) The force transmission in the structure is clear and simple; (2) The connection structure is reasonable, taking into account both the force transmission and the strengthening of the cross-sectional structure of the node area; (3) The construction is convenient, with the adoption of integrated connection consideration, and no loose parts on site except for bolts, and the fewer types of components on site facilitate node installation; (4) The standardization is high, all components are prefabricated in the factory, and there is no welding operation on site, realizing a high degree of industrialization of component manufacturing; at the same time, after adopting this node construction method, all components have high generality and are easier to process and prepare in the factory; (5) The construction accuracy is controllable, and the use of this node connection effectively optimizes the factor of large cumulative construction error in the traditional beam priority system where the full hinge connection is used. The beam-beam connection of this node has strong constraint, and the installation error is easy to control. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figures 1-5 As shown, a prefabricated steel beam hinged joint structure includes a main beam 1 and a secondary beam 2. Both the main beam and the secondary beam are H-shaped steel beams, each including a web and flanges fixedly connected to the upper and lower sides of the web. Multiple sets of connection holes 5 are axially provided on the web and flanges of both the main beam and the secondary beam, using a standardized module of 100mm or N*100mm. The secondary beam can have multiple levels, with connection ends corresponding to both ends of each secondary beam or secondary beam of level two or higher. A web connecting plate 6 is fixedly installed at the end of the web of the connection end. Grooves are provided on the upper and lower sides of the web of the connection end, and flange connecting plates 7 are fixedly installed within these grooves. Mounting holes are provided on the web connecting plates and flange connecting plates corresponding to each set of connection holes. The connection holes and mounting holes are standard bolt holes, and the connection is secured using standard bolts 3 and standard nuts 4.

[0014] The groove depth matches the thickness of the flange connecting plate. The web connecting plate is fixedly connected to the end of the web at the connecting end by welding, and the flange connecting plate is fixedly connected to the grooves on the upper and lower sides of the web by welding.

[0015] like Figures 3-5 As shown, the end connection of the secondary beam adopts an integrated standard connection structure manufactured in the factory, thus adapting to various structural spans, standardizing the connection, and realizing the standardization and industrialization of component production and installation of steel structure buildings.

[0016] The secondary beam end connection is a standard secondary beam end, and the integrated joint node is mainly composed of a web connection plate, a flange connection plate, and a modified main structural beam. Its structural design allows for a simple and clear transfer of vertical loads from the main structure to the web via the web connection plate. Simultaneously, within the joint area, the flange connection plate connects the secondary beam portion of the web structure, which not only shares the downward vertical force from the flange portion but also enhances the stability of the structural surface, improves the torsional resistance of the joint area section, and effectively increases the constraint of the main and secondary structures at the hinged joint. This optimizes the cumulative error at the installation joint during steel beam installation, greatly facilitating the installation accuracy and construction control of prefabricated steel structures.

[0017] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
