Abstract
Description
Technical Field
[0001] This utility model relates to the field of inclined beam connection, and in particular to an inclined beam connection structure with stable connection. Background Technology
[0002] A slanted beam connection structure refers to a mechanical system that reliably connects a slanted beam to a vertical column, horizontal beam, or other components through specific node construction. Its core function is to effectively transfer the axial force, shear force, and bending moment borne by the slanted beam to the main structure. This structure needs to adopt hinged, semi-rigid, or rigid connection forms according to the slanted beam's inclination angle and stress characteristics. Common constructions include end plate bolt connections, welded nodes, and pin hinges. During the design, geometric adaptability, load transfer path, and seismic performance must be comprehensively considered to ensure the stability and deformation coordination of the overall structure.
[0003] When double inclined beams are directly spliced together and supported by themselves, all loads are transferred through the outside of the inclined beams, which will cause the inclined beams to bear excessive axial pressure and bending moment, thus causing significant bending deformation. At the same time, stress superposition effect occurs at the connection due to concentrated force, which further aggravates the load burden in the local area. This stress state will not only reduce the overall stability of the inclined beams, but may also affect the installation accuracy and long-term reliability of the structure due to excessive stress at the connection nodes. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable inclined beam connection structure that enhances the overall resistance of the inclined beam and improves the shear resistance at the connection point.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A stable inclined beam connection structure includes a supporting inclined beam for splicing support. A reinforcing frame is nested at the bottom inner side of the supporting inclined beam. Bottom bolts are threaded to the bottom ends of the supporting inclined beams. Second nuts are fixedly connected to the front ends of the bottom bolts. Flip-connecting assemblies are installed on both sides of the reinforcing frame to achieve overall stability and installation. A connecting inclined block is fixedly connected to the top of the reinforcing frame. An interface reinforcement assembly is installed on the outside of the connecting inclined block to strengthen the connection at the splice.
[0007] Furthermore, the interface reinforcement component includes through-posts located on both sides of the connecting inclined block, with an upper bolt rotatably connected inside the through-post, a third nut fixedly connected to the front end of the upper bolt, the outer side of the connecting inclined block penetrating both sides of the supporting inclined beam, and the outer thread of the upper bolt connected to the rear side of the supporting inclined beam.
[0008] Furthermore, the flip-connecting assembly includes fixed seats located on both sides of the reinforcing frame. Each fixed seat is rotatably connected to a supporting flip-up rod. The outer sides of the supporting flip-up rods are respectively attached to the inner sides of the supporting inclined beam. The inner threads of the supporting flip-up rods are connected to a center bolt, and the outer threads of the center bolts are connected to the inside of the supporting inclined beam.
[0009] Furthermore, a first nut is fixedly connected to the front end of the center bolt.
[0010] Furthermore, a limiting slot is provided on the inner side of the supporting inclined beam, and multiple limiting plates are fixedly connected to both sides of the connecting inclined block, with the outer side of the limiting plate nested inside the limiting slot.
[0011] Furthermore, the internal thread of the connecting inclined block is connected to a main body fixing bolt, and the external thread of the main body fixing bolt is connected to the connecting protrusion of the supporting inclined beam.
[0012] Furthermore, the upper bolt is externally fixedly connected with multiple anti-detachment sleeves, and the external anti-detachment sleeves are rotatably connected to the inside of the insert post.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the reinforcing frame is nested at the bottom of the inclined beam to directly bear the main axial pressure, avoiding excessive load on the inclined beam body. Then, the fixed seat 3 and the support flipping rod 4 form a rigid triangular support system, which converts the bending moment into pressure and transmits it to the inclined beam body, significantly reducing the risk of bending deformation.
[0015] 2. In this utility model, a tenon-and-mortise interlocking structure is formed by connecting the limiting plate of the inclined block and the limiting groove of the inclined beam. The insert column is inserted into the interior of the connecting inclined block and the supporting inclined beam and is fixed by the upper bolt, which effectively resists the lateral shear force and improves the shear resistance of the node.

[0023] 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.
[0024] Reference Figures 1-3 This utility model provides an embodiment of a stable inclined beam connection structure, including a supporting inclined beam 1 for splicing support. A reinforcing frame 2 is nested at the bottom inner side of the supporting inclined beam 1. Bottom bolts 14 are threaded to the bottom ends of the supporting inclined beam 1, and second nuts 6 are fixedly connected to the front ends of the bottom bolts 14. Flip-connecting assemblies are installed on both sides of the reinforcing frame 2 to achieve overall stability and installation. A connecting inclined block 8 is fixedly connected to the top of the reinforcing frame 2, and an interface reinforcement assembly is installed on the outside of the connecting inclined block 8 to strengthen the connection at the splice point. The flip-connecting assembly includes fixed seats 3 located on both sides of the reinforcing frame 2. (Refer to...) Figure 4 The fixed base 3 is rotatably connected to the support flipping rod 4. The outer side of the support flipping rod 4 is respectively attached to the inner side of the support inclined beam 1. The internal thread of the support flipping rod 4 is connected to the center bolt 15. The external thread of the center bolt 15 is connected to the inside of the support inclined beam 1. The front end of the center bolt 15 is fixedly connected to the first nut 5.
[0025] When the inclined beam 1 is spliced and installed, the reinforcing frame 2 built into its bottom serves as the main load-bearing component, directly bearing and transmitting the axial load through the nested structure. At the same time, the fixed seats 3 set on both sides of the reinforcing frame and the support flipping rod 4 are fastened together by the center bolt 15 to form a stable triangular support system. This design cleverly transforms the bending moment load into axial pressure and effectively transmits it to the main structure of the inclined beam, thereby significantly suppressing the bending deformation trend of the inclined beam and greatly improving the stiffness and stability of the overall structure.
[0026] Reference Figure 1 , Figure 3 and Figure 4 The interface reinforcement component includes through-posts 11 located on both sides of the connecting inclined block 8. An upper bolt 16 is rotatably connected inside the through-post 11, and a third nut 7 is fixedly connected to the front end of the upper bolt 16. The connecting inclined block 8 extends through both sides of the supporting inclined beam 1. The external thread of the upper bolt 16 is connected to the rear side of the supporting inclined beam 1. A limiting slot 10 is provided on the inner side of the supporting inclined beam 1. Multiple limiting plates 9 are fixedly connected to both sides of the connecting inclined block 8. The external threads of the limiting plates 9 are nested inside the limiting slots 10. A main fixing bolt 12 is threaded inside the connecting inclined block 8, and the external threads of the main fixing bolt 12 are connected to the connecting protrusion of the supporting inclined beam 1. (Refer to...) Figure 5 The upper bolt 16 is externally fixedly connected to multiple anti-detachment round sleeves 13, and the external anti-detachment round sleeves 13 are rotatably connected to the inside of the through post 11.
[0027] At the top of the structure, the connecting wedge block 8 is precisely embedded in the limiting slot 10 inside the inclined beam. The limiting plates 9 arranged symmetrically on both sides form a tenon-and-mortise anti-shear structure, which forms a tight mechanical engagement with the slot. At the same time, the main fixing bolt 12 passes through the connecting wedge block and the protrusion of the inclined beam to achieve a longitudinal rigid connection. To further enhance the strength of the node, the through-post 11 set at the interface and the upper bolt 16 are fastened to the rear end of the inclined beam by threads. Together with the anti-loosening round sleeve 13, a three-dimensional constraint system is formed, which not only effectively disperses the concentrated stress of the splicing node, but also significantly improves the ability of the connection part to resist transverse shear force, ensuring the stability and reliability of the node under complex stress conditions.
[0028] Working principle: When the inclined beam 1 is spliced, the reinforcing frame 2 at its bottom acts as the core load-bearing body nested inside the beam, directly bearing the main axial pressure. The fixed seats 3 on both sides of the reinforcing frame and the support flipping rod 4 are locked together by the center bolt 15 to form a rigid triangular support, which converts the bending moment into pressure and transmits it to the inclined beam body, suppressing bending deformation. The connecting inclined block 8 at the top is embedded in the inner limiting groove 10 of the inclined beam, and the limiting plates 9 on both sides form a tenon and mortise anti-shear mechanism. At the same time, the main fixing bolt 12 passes through the inclined block and the inclined beam protrusion to strengthen the longitudinal connection. The through column 11 at the interface and the upper bolt 16 are fastened to the rear end of the inclined beam by threads, which, together with the anti-loosening round sleeve 13, form a multi-directional constraint to disperse the stress at the splicing node. Finally, the load is transferred in layers through the reinforcing frame, flipping rod, tenon and mortise and bolt system to avoid stress concentration and ensure overall rigidity and installation accuracy.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
