Description

Technical Field

[0001] This utility model relates to the field of rigid connection technology, specifically to a rigid connection device for H-shaped steel beams and H-shaped steel columns. Background Technology

[0002] H-beams have a wide range of applications, primarily in: various civil and industrial building structures; large-span industrial plants and modern high-rise buildings, especially in areas with frequent earthquakes and under high-temperature conditions; large bridges requiring high load-bearing capacity, good cross-sectional stability, and long spans; heavy equipment; highways; ship frames; mine support; foundation treatment and dam engineering; and various machine components. The section modulus, moment of inertia, and corresponding strength of H-beams are significantly superior to those of ordinary I-beams of the same weight. Used in metal structures with varying requirements, H-beams demonstrate superior performance in bearing bending moments, compressive loads, and eccentric loads, significantly increasing load-bearing capacity compared to ordinary I-beams.

[0003] Some connection devices require a lot of welding, bolt tightening and other operations on site, which not only requires more manpower and time, but also the on-site working environment is relatively poor, which will affect the efficiency and quality of the work.

[0004] To address this issue, we propose a rigid connection device for H-beams and H-columns. Utility Model Content

[0005] The purpose of this utility model is to provide a rigid connection device for H-shaped steel beams and H-shaped steel columns, so as to solve the problems mentioned in the background art, such as the need for more manpower and time, and the impact of on-site construction on efficiency and quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rigid connection device for H-shaped steel beams and H-shaped steel columns, comprising an H-shaped steel column, two stiffening plates welded inside the H-shaped steel column, a beam-column connecting plate fixedly connected between the stiffening plates at the middle, round holes on both sides of the beam-column connecting plate, an H-shaped steel beam connected to the round holes by bolts, an H-shaped groove on one side of the H-shaped steel beam, through connecting holes on both sides of the H-shaped groove, bolts passing through the connecting holes and round holes, and nuts threaded onto both sides of the bolts.

[0007] Preferably, the H-shaped steel beams and H-shaped steel columns are supported by support members. These support members are snap-fitted onto the H-shaped steel columns and H-shaped steel beams using fasteners. The support members form an additional support structure between the H-shaped steel beams and H-shaped steel columns, effectively enhancing the overall stiffness and stability of the beam-column connection. They can share some of the load borne by the beams and columns, reducing deformation of the joint during stress, improving the structure's resistance to lateral forces and torsion, ensuring the safety and reliability of the structure under complex stress conditions, and preventing a decline in overall structural performance or even damage due to excessive joint deformation.

[0008] Preferably, the snap-fit ​​component includes a placement groove, a locking block, a spring, and a connecting plate. The placement groove is formed on all four sides of the snap-fit ​​component. One end of the spring is fixedly connected to the inside of the placement groove, and the other end of the spring is fixedly connected to the connecting plate. The bottom of the locking block is fixedly connected to the surface of the connecting plate. Using snap-fit ​​components to connect support members to H-shaped steel columns and H-shaped steel beams offers advantages in terms of convenient and rapid installation compared to traditional welding or bolting methods. The snap-fit ​​method eliminates the need for complex welding processes or numerous bolt tightening operations, greatly improving construction efficiency and shortening the construction cycle.

[0009] Preferably, the locking block engages with a first insertion hole on the H-shaped steel column and a second insertion hole on the H-shaped steel beam. This engagement with the insertion holes achieves the locking function, tightly connecting the support member to the H-shaped steel column and beam, forming a unified load-bearing system. The insertion holes provide accurate positioning for the locking block, ensuring the support member can be accurately installed in the predetermined position.

[0010] Preferably, the locking point of the locking block is beveled. During the locking process, the beveled design makes it easier for the locking block to slide into the first insertion hole on the H-shaped steel column and the second insertion hole on the H-shaped steel beam, reducing installation resistance and improving installation efficiency.

[0011] Preferably, the support members are respectively snapped onto the upper and lower sides of the H-beam using snap-fit ​​devices, and also snapped onto the H-beam column. Snapping the support members onto the upper and lower sides of the H-beam provides more uniform and stable support. This arrangement effectively balances the bending moment and shear force generated during the loading process of the H-beam, reduces deformation and stress concentration, and improves the load-bearing capacity and service life of the H-beam.

[0012] Preferably, the stiffening plate is arranged perpendicular to the inner wall of the H-shaped steel column. This perpendicular arrangement allows the stiffening plate to fully exert its effect of enhancing the local stiffness and strength of the H-shaped steel column. When subjected to complex stresses transmitted from the beam-column connection, the vertically arranged stiffening plate can more effectively resist the bending and torsional deformation of the steel column, preventing local instability.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This rigid connection device for H-beams and H-columns significantly enhances the overall rigidity and stability of the beam-column connection node by setting a support between the H-beam and the H-column. The support shares part of the load borne by the beam and column, reduces the deformation of the node during the stress process, enables the structure to maintain better integrity when subjected to complex loads, and improves the structure's ability to resist lateral forces and torsion.

[0015] 2. This rigid connection device for H-beams and H-columns uses snap-fit ​​connectors to connect the support components to the H-beams and columns. Compared to traditional welding or bolt connections, it offers advantages such as convenient and rapid installation. The snap-fit ​​method eliminates the need for complex welding processes, avoiding welding defects and thermal deformation that may occur during welding. It also eliminates the need for extensive bolt tightening, simplifying the installation process, improving construction efficiency, shortening the construction cycle, and reducing construction costs.

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1-5 This utility model provides a technical solution: a rigid connection device for H-shaped steel beams and H-shaped steel columns, including an H-shaped steel column 1. Two stiffening plates 4 are welded inside the H-shaped steel column 1, and the stiffening plates 4 are perpendicular to the inner wall of the H-shaped steel column 1. This enhances the local stiffness and strength of the H-shaped steel column 1 at the beam-column connection. When subjected to complex stresses transmitted from the beam-column connection, it can effectively resist bending and torsional deformation of the steel column, prevent local instability of the steel column, ensure the mechanical properties of the connection and the overall steel column, and improve the safety and reliability of the structure. A beam-column connection plate 5 is fixedly connected in the middle between the stiffening plates 4, providing a direct connection interface for the connection between the H-shaped steel beam 2 and the H-shaped steel column 1. The circular holes 501 on both sides of the plate 501 cooperate with the connection holes 203 on the H-shaped steel beam, and are connected by bolts, realizing a rigid connection between the beam and the column. This allows the beam and column to work together, effectively transmitting internal forces such as bending moment, shear force, and axial force, ensuring the structural performance under various working conditions. The beam-column connecting plate 5 has round holes 501 on both sides. H-beams 2 are connected to these holes 501 via bolts 6. One side of the H-beam 2 has an H-shaped slot 202, with through-holes 203 on both sides. Bolts 6 pass through the through-holes 203 and the round holes 501, providing space for bolt positioning and installation. This ensures the bolts can accurately pass through the beam-column connecting plate and the H-beam, achieving a reliable connection and guaranteeing connection accuracy. Nuts are threaded onto both sides of the bolts 6. The H-beam 2 and H-column 1 are supported by a support member 3, which is secured to both the H-beam and H-column 2 by snap-fit ​​members 301. The support member 3 is snapped onto the upper and lower sides of the H-beam 2 and also to the H-column 1 via snap-fit ​​members 301. This forms an additional support structure between the H-beam and H-column, effectively enhancing the overall rigidity and stability of the beam-column connection node. It can share some of the load borne by the beams and columns, reduce the deformation of the joints during the stress process, improve the structure's ability to resist lateral forces and torsion, ensure the safety and reliability of the structure under complex stress conditions, and avoid the overall performance degradation or even failure of the structure due to excessive joint deformation. The support members are respectively snapped onto the upper and lower sides of the H-beam 2, providing more uniform and stable support for the H-beam 2, balancing the bending moment and shear force generated by the H-beam 2 during the stress process, and reducing the deformation and stress concentration of the H-beam 2.

[0025] The snap-fit ​​component 301 includes a placement groove 302, a snap-fit ​​block 303, a spring 304, and a connecting plate 305. The placement groove 302 is formed on all four sides of the snap-fit ​​component 301. One end of the spring 304 is fixedly connected to the inside of the placement groove 302, and the other end of the spring 304 is fixedly connected to the connecting plate 305. The bottom of the snap-fit ​​block 303 is fixedly connected to the surface of the connecting plate 305. The snap-fit ​​block 303 snaps into the insertion hole 101 on the H-shaped steel column 1 and the insertion hole 201 on the H-shaped steel beam 2. The snap-fit ​​point of the snap-fit ​​block 303 is beveled. During the snap-fit ​​process, the beveled design makes it easier for the snap-fit ​​block to slide into the insertion hole 101 on the H-shaped steel column and the insertion hole 201 on the H-shaped steel beam, reducing installation resistance and improving installation efficiency. At the same time, when the snap-fit ​​block 303 is fully snapped into the insertion hole, the beveled surface fits tightly against the insertion hole wall, increasing the friction of the snap-fit ​​and improving the firmness of the snap-fit.

[0026] Working principle: The H-beam 2 transfers the floor or roof load it bears to the H-beam column 1 through the beam-column connection plate 5 connected by bolts 6. In this process, the stiffening plate 4 is perpendicular to the inner wall of the H-beam column 1, which enhances the local stiffness and strength of the steel column at the beam-column connection, effectively resisting the complex stress generated by the load transfer, preventing the steel column from bending and torsional deformation at the connection, and ensuring the mechanical properties of the connection and the overall steel column.

[0027] Support member 3 is attached to the upper and lower sides of H-beam 2 and H-column 1 via snap-fit ​​members 301, forming an additional support structure. When the beam and column are subjected to loads, support member 3 can share part of the load borne by the beam and column, reducing the deformation of the joints during the stress process and improving the structure's resistance to lateral forces and torsion. For example, under horizontal forces such as wind loads or seismic loads, support member 3 can effectively balance the bending moment and shear force generated by H-beam 2 during the stress process, reducing the deformation and stress concentration of H-beam 2, and ensuring the safety and reliability of the structure under complex stress conditions.

[0028] One end of the spring 304 inside the snap-fit ​​component 301 is fixed inside the placement groove 302, and the other end is connected to the connecting plate 305. The snap-fit ​​block 303 is fixed to the surface of the connecting plate 305. During installation, when the snap-fit ​​block 303 contacts the edge of the insertion hole 101 on the H-shaped steel column 1 and the insertion hole 201 on the H-shaped steel beam 2, due to the inclined surface of the snap-fit ​​point, the snap-fit ​​block 303 will be subjected to an inward component force under the guidance of the inclined surface. This causes the connecting plate 305 to compress the spring 304, and the snap-fit ​​block 303 will retract into the placement groove 302, thus smoothly sliding into the insertion hole. After the snap-fit ​​block 303 is fully inserted into the insertion hole, the elastic force of the spring 304 causes the connecting plate 305 to push the snap-fit ​​block 303 outward, so that the inclined surface of the snap-fit ​​block 303 fits tightly against the wall of the insertion hole, increasing the friction of the snap-fit, thereby ensuring the firmness of the snap-fit ​​and realizing the reliable connection between the support component 3 and the H-shaped steel column 1 and the H-shaped steel beam 2.
