Description

Technical Field

[0001] This utility model relates to the field of industrial building construction technology, specifically a connection node structure between a prestressed beam and a beam-column structure. Background Technology

[0002] Industrial upgrading is a new industrial development model that refers to shifting industrial production activities from traditional single-story factories to multi-story or high-rise buildings. This model typically appears in cities or regions with limited land resources, improving land use efficiency through the utilization of vertical space. Because industrial upgrading transforms factories from single-story to multi-story or high-rise buildings, and industrial production involves the operation of numerous large industrial equipment, which are heavy and vibrate significantly during operation, the requirements for beam-to-beam and beam-to-column connections in the factory building are higher than in ordinary buildings. Therefore, existing beam-to-column connection node structures cannot meet the needs of industrial upgrading. Utility Model Content

[0003] The purpose of this utility model is to provide a connection node structure between prestressed beams and beams and columns to solve the problems of the prior art mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A prestressed beam and beam-column connection structure includes several beams and columns and a prestressed beam. Each beam and column has a through hole through which the prestressed beam passes. An annular plate is located above the through hole, and a partition plate is provided on the annular plate. The partition plate divides the annular plate into several cavities corresponding to the beam positions. Several reinforcing bars are fixed to one end of each prestressed beam. Each reinforcing bar passes through the cavity from the top of the prestressed beam and through the beam-column before being fixed to the end of the prestressed beam on the other side. A reinforcing plate is provided inside the beam-column corresponding to the positions where the reinforcing bars pass through.

[0006] Furthermore, one end of the reinforcing plate is welded to the inner wall of the beam and column, and the reinforcing plate has a through hole in the middle with a diameter larger than that of the beam reinforcement.

[0007] Furthermore, a support plate is provided at the lower part of the through hole, the support plate abuts against the bottom of the prestressed beam, the bottom of the prestressed beam has a groove, and the support plate corresponding to the groove has a slot.

[0008] Furthermore, the groove and the slot are used to fix the support plate to the prestressed beam by welding.

[0009] Furthermore, the bottom of the support plate is provided with several reinforcing ribs, which are arranged to avoid the groove.

[0010] Furthermore, the prestressed beam includes a main beam and secondary beams. The main beam is located between the outer beams and columns, connecting several outer beams and columns to form an external frame. Several main beams are also arranged laterally within the frame, and several secondary beams are arranged longitudinally within the frame.

[0011] Furthermore, the main beam and the secondary beam are hinged. The main beam has notches on both sides corresponding to the positions of the secondary beams. Each section of the secondary beam has a corbel at one end. The corbel of each section of the secondary beam is placed on one side of the notch. The two sections of the secondary beam are placed at the notches of the main beam and have a through-beam channel. The through-beam channel is used for the beam reinforcement of the main beam to pass through.

[0012] Furthermore, anchorages are provided at both ends of the prestressed beam, and the beam reinforcement is fixed to the upper part of the prestressed beam through the anchorages. Stirrups are also provided on the upper part of the prestressed beam, and the stirrups limit the beam reinforcement to be located above the prestressed beam.

[0013] Furthermore, the beams and columns are steel-concrete composite columns or steel-box concrete columns.

[0014] Furthermore, the connection node structure between the prestressed beam and the beam-column is used for industrial upstairs installation. Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model enhances the bending, shear and crack resistance of the beam by arranging the prestressed beam and beam reinforcement, thereby improving the overall strength and stability of the structure; the reinforcement plates installed inside the beam and column enhance the local strength of the beam and column, and prevent the beam reinforcement from causing damage to the beam and column when passing through it.

[0016] 2. This utility model divides the connection node between the prestressed beam and the beam-column into several cavities through the ring plate and partition plate above the through hole, so that the beam reinforcement can pass through in an orderly manner, thereby enhancing the rigidity and load-bearing capacity of the node; the support plate below the through hole is welded to the groove at the bottom of the prestressed beam, thereby enhancing the firmness of the node connection and preventing loosening or deformation at the node.

[0017] 3. This utility model simplifies the installation and fixing of the secondary beam by using a hinged connection between the main beam and the secondary beam of the prestressed beam, while also adapting to the deformation requirements of the structure.

[0018] In summary, this utility model, through the hinged connection of the primary and secondary beams of the prestressed beam, adapts to the deformation requirements of the structure, improving seismic resistance and durability. The coordinated action of the ring plate and partition plate above the through-hole in the beam and column, the support plate below the through-hole, the reinforcing ribs under the support plate, the groove welded to the bottom of the prestressed beam, and the reinforcing plates inside the beam and column enhances the robustness of the joint connection, preventing loosening or deformation at the joint. This allows the joint structure to withstand larger loads, meeting the structural strength requirements for industrial multi-story buildings. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, a connection node structure between a prestressed beam and a beam-column includes several beam-columns 100 and prestressed beams 200. Each beam-column 100 has a through hole through which the prestressed beam 200 passes. An annular plate 110 is provided above the through hole, and a partition plate 120 is provided on the annular plate 110. The partition plate 120 divides the annular plate 110 into several cavities corresponding to the beam positions. Several beam reinforcements 300 are fixed to one end of each prestressed beam 200. Each beam reinforcement 300 passes through the cavity from the top of the prestressed beam 200 and is then fixed to the other end of the prestressed beam 200. A reinforcing plate 150 is provided inside the beam-column 100 corresponding to the positions where the beam reinforcement 300 passes through.

[0027] like Figure 4As shown, one end of the reinforcing plate 150 is welded to the inner wall of the beam-column 100. The reinforcing plate 150 has a through hole in the middle with a diameter larger than that of the beam reinforcement 300. The reinforcing plate 150 can increase the strength around the through hole in the inner wall of the beam-column 100, ensuring that the supporting force of the beam-column 100 remains unchanged.

[0028] like Figure 3-4 As shown, a support plate 130 is provided at the lower part of the through hole. The support plate 130 abuts against the bottom of the prestressed beam 200. A groove 210 is opened at the bottom of the prestressed beam 200, and a slot 131 is opened on the support plate 130 corresponding to the groove 210.

[0029] In actual implementation, the groove 210 and the slot 131 are used to fix the support plate 130 to the prestressed beam 200 by overlay welding.

[0030] like Figure 3 As shown, the bottom of the support plate 130 is provided with a plurality of reinforcing ribs 140, which are arranged to avoid the groove 210.

[0031] like Figure 1 As shown, the prestressed beam 200 includes a main beam 220 and a secondary beam 230. The main beam 220 is located between the outer beams and columns 100, connecting several outer beams and columns 100 to form an external frame. Several main beams 220 are also arranged laterally within the frame, and several secondary beams 230 are arranged longitudinally within the frame.

[0032] like Figure 5 As shown, the main beam 220 and the secondary beam 230 are hinged. The hinged connection only transmits shear force and allows the secondary beam 230 to rotate a certain amount on the main beam 220, but it cannot transmit bending moment, so as to reduce stress concentration at the connection node. The main beam 220 has notches 221 on both sides corresponding to the position of the secondary beam 230. Each section of the secondary beam 230 has a corbel (not shown in the figure) at one end of its bottom. The corbel of each section of the secondary beam 230 is placed on one side of the notch 221. Two sections of the secondary beam 230 are placed at the notch 221 of the main beam 220 and a through-beam channel 231 is left. The through-beam channel 231 is used for the beam reinforcement 300 of the main beam 220 to pass through.

[0033] like Figure 5As shown, the prestressed beam 200 is equipped with anchorages (not shown in the figure) at both ends. The beam reinforcement 300 is fixed to the upper part of the prestressed beam 200 through the anchorages. The beam reinforcement 300 is tensioned using hydraulic jacks and other equipment to achieve the designed tension force. The prestressed beam 200 is also equipped with stirrups 310 on the upper part. After the stirrups 310 confine the beam reinforcement 300 above the prestressed beam 200, concrete is poured. This type of prestressed beam 200 does not require support during the entire construction stage, simplifying the construction steps.

[0034] In actual implementation, the beam-column 100 is a steel-concrete composite column or a steel-box concrete column.

[0035] In actual implementation, the connection node structure between the prestressed beam 200 and the beam-column 100 is used for industrial upstairs construction.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
