A connection structure for H-shaped steel structures

Abstract

This utility model relates to the field of steel structure connection, specifically a connection structure for an H-shaped steel structure, including a main beam with reinforcing plates fixedly connected to both sides. A secondary beam is provided on one side of the main beam, and two connecting plates are provided at the connection point between the secondary beam and a reinforcing plate. Compared with the prior art, in the initial state, one side of the movable plate contacts the side of the baffle, and the force of the tension spring facilitates the clamping of the bolt column by the first and second clamping plates, thereby supporting the bolt column. This facilitates the pre-constraint of the bolt column on one side of the connecting plate, making subsequent installation easier. When one side of the first and second clamping plates contacts the side of the connecting plate, the bolt head is continuously rotated, causing the bolt head to press against the first and second clamping plates, which move outwards from the bolt head, facilitating the bolt column to pass through the mounting hole and connect with the nut, thus completing the connection between the main beam and the secondary beam.

Description

Technical Field

[0001] This utility model relates to the field of steel structure connection, specifically a connection structure for H-shaped steel structures. Background Technology

[0002] H-beams are steel with a cross-sectional shape resembling the letter H. Due to their optimized cross-sectional area distribution and reasonable strength-to-weight ratio, they are widely used in various engineering structures. The inner and outer flanges of H-beams are parallel or nearly parallel, and the flange ends are at right angles, hence the name parallel flange H-beams. They are used in metal structures with different requirements, and they demonstrate superior performance in bearing bending moments, compressive loads, and eccentric loads. They can greatly improve the load-bearing capacity compared to ordinary H-beams. Usually, when connecting adjacent H-beams, connecting plates, reinforcing plates, and reinforcing bolts are used for fixed connection.

[0003] Chinese patent CN211973858U discloses a connection node structure between an H-beam and an H-column. By setting a fixing seat and reinforcing ribs, the vertical connection between the H-beam and the H-column is made more stable. The supporting ribs on the fixing seat further reinforce the structure and resist the elastic deformation caused by the clamping plate. Since the fixing seat and reinforcing ribs are connected and fixed to the H-beam and H-column by bolts, the H-beam and H-column are detachable. The self-locking nuts on the first, second, and third bolts can prevent the connection structure from loosening and causing safety hazards.

[0004] However, the patent has the following defects in operation: In the actual construction process, it is necessary to first align the fixing seat and the reinforcing rib with the H-shaped steel beam and the H-shaped steel column respectively. Then, the workers manually match several bolts with several mounting holes one by one before installation. This process lacks a mechanism that can pre-install several bolts, which means that after installing one bolt, the workers need to pick up the next bolt and perform the step of positioning before installation. The bolt installation method is not convenient enough. Utility Model Content

[0005] This utility model aims to provide a connection structure for H-shaped steel structures, mainly to solve the technical problem that the existing technology lacks a mechanism for pre-installing several bolts, which causes workers to need to pick up the next bolt and position it before installing it after installing one bolt, making the bolt installation method inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A connection structure for an H-shaped steel structure includes a main beam with reinforcing plates fixedly connected to both sides. A secondary beam is provided on one side of the main beam, and two connecting plates are provided at the connection between the secondary beam and a reinforcing plate. The two connecting plates are connected by bolt columns, and two sets of bolt columns are provided, each set penetrating both sides of the reinforcing plate and both sides of the secondary beam. A bolt head is fixedly connected to one end of each bolt column. A movable plate is provided on one side of a connecting plate, and a support rod for sliding the movable plate is fixedly connected to one side of the connecting plate. A set of mounting grooves is provided on both sides of the movable plate. A first clamping plate is slidably mounted on the top of the mounting groove, and a second clamping plate is slidably mounted on the bottom of the mounting groove. A tension spring is provided between the first clamping plate and the second clamping plate. The outer wall of the bolt column is located between the first clamping plate and the second clamping plate. Guide grooves are provided on the inner sides of both the first clamping plate and the second clamping plate.

[0007] The working principle and beneficial effects of this utility model: 1. Working Principle: In the initial state, the tension spring facilitates the clamping of the bolt column by the first and second clamping plates, thus supporting the bolt column and pre-restricting it to one side of a connecting plate for easy subsequent installation. When the main beam and secondary beam are aligned, the bolt column is screwed into the nut, causing the bolt head to contact the guide groove on one side of the first clamping plate and the guide groove on the other side of the second clamping plate, which in turn moves the moving plate closer to the connecting plate. When one side of the first and second clamping plates contacts one side of the connecting plate, the bolt head is continuously rotated, causing it to press against the first and second clamping plates, which then move outwards from the bolt head, allowing the bolt column to pass through the mounting hole and connect with the nut, thus completing the connection between the main beam and the secondary beam.

[0008] 2. Beneficial effects: (1) In the initial state, one side of the moving plate contacts the side of the baffle, and the force of the tension spring facilitates the clamping of the bolt column by the first and second clamping plates, thereby supporting the bolt column and pre-limiting the bolt column to one side of the connecting plate for easy subsequent installation. Due to the friction between the outer wall of the rubber sleeve and the guide hole, the moving plate will not move arbitrarily. When the main beam and the secondary beam are aligned, the bolt column is screwed into the nut, so that the bolt head end contacts the guide groove on one side of the first clamping plate and the guide groove on one side of the second clamping plate, and drives the moving plate to move closer to the connecting plate. When one side of the first clamping plate and the second clamping plate contacts one side of the connecting plate, the bolt head end is continuously rotated, so that the bolt head end is squeezed against the first and second clamping plates, so that the first and second clamping plates move to the outside of the bolt head end, so that the bolt column passes through the mounting hole and connects with the nut, completing the connection between the main beam and the secondary beam.

[0009] Preferably, the two sets of bolt columns are arranged in a rectangular array, and a number of nuts are provided on the side of the connecting plate away from the bolt columns, and each set of bolt columns corresponds to a number of nuts; when the bolt column passes through the reinforcing plate and the secondary beam and is connected to the nut, one side of the bolt head is tightly fitted with one side of a connecting plate, thereby completing the connection between the main beam and the secondary beam through the reinforcing plate.

[0010] Preferably, there are two support rods, each with a rubber sleeve on its outer wall. A baffle is fixedly connected to one end of each support rod. Two guide holes are opened through both sides of the movable plate, and the movable plate is slidably connected to the outer wall of the rubber sleeve through the guide holes. Due to the friction between the outer wall of the rubber sleeve and the guide holes, the movable plate will not move arbitrarily.

[0011] Preferably, both connecting plates have several mounting holes on their outer sides, and the outer wall of each bolt column passes through several mounting holes. When the main beam and the secondary beam are aligned, the two connecting plates are placed on both sides of the reinforcing plate and the secondary beam respectively, so that the mounting holes of the two connecting plates are aligned, and the bolt columns are screwed into the nuts.

[0012] Preferably, the two sets of mounting slots are symmetrically arranged, and several mounting slots in each set are arranged in a linear array at equal intervals. A fixing rod is fixedly connected inside the mounting slot, and a first slider is slidably connected to the top of the outer wall of the fixing rod. One end of the first clamping plate is fixedly connected to one side of the first slider, and a second slider is slidably connected to the bottom of the outer wall of the fixing rod. One end of the second clamping plate is fixedly connected to one side of the second slider. When the first clamping plate and the second clamping plate move outward from the bolt head end through the two guide slots, the first clamping plate and the second clamping plate respectively drive the first slider and the second slider to slide on the fixing rod, thereby increasing the distance between the first slider and the second slider, and stretching the tension spring.

[0013] Preferably, one end of the tension spring is fixedly connected to one side of the first slider, and the other end is fixedly connected to one side of the second slider. In the initial state, due to the force of the tension spring, the first and second clamping plates can clamp the bolt column, thereby supporting the bolt column and pre-limiting the bolt column to one side of a connecting plate, which is convenient for subsequent installation.

[0014] Preferably, the first clamping plate and the second clamping plate are located on one side of the bolt head end, and the bolt head end side is in contact with the guide groove on one side of the first clamping plate and the guide groove on one side of the second clamping plate; when one side of the first clamping plate and the second clamping plate are in contact with one side of a connecting plate, the bolt head end is continuously rotated, so that the bolt head end is pressed against the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate move outward of the bolt head end through the two guide grooves respectively.

[0017] 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.

[0018] Please see Figures 1-6 As shown, a connection structure for an H-shaped steel structure includes a main beam 1, with reinforcing plates 2 fixedly connected to both sides of the main beam 1. A secondary beam 3 is provided on one side of the main beam 1. Two connecting plates 4 are provided at the connection between the secondary beam 3 and a reinforcing plate 2. The two connecting plates 4 are connected by bolt columns 18, and two sets of bolt columns 18 are provided in a rectangular array. Several mounting holes 5 are opened on the outer side of each connecting plate 4. Several mounting holes 5 pass through the outer wall of each set of bolt columns 18. Several nuts 20 are provided on the side of the connecting plate 4 away from the bolt columns 18, and each set of bolt columns 18 corresponds to several nuts 20. When the main beam 1 and the secondary beam 3 are aligned, the two connecting plates 4 are placed on both sides of the reinforcing plate 2 and the secondary beam 3 respectively, so that the mounting holes 5 of the two connecting plates 4 are aligned. Two sets of bolt columns 18 pass through both sides of the reinforcing plate 2 and both sides of the secondary beam 3 respectively. Each set of bolt columns 18 has a bolt head end 19 fixedly connected to one end. A movable plate 10 is provided on one side of a connecting plate 4, and a support rod 6 for sliding the movable plate 10 is fixedly connected to one side of the connecting plate 4. There are two support rods 6, and rubber sleeves 7 are fitted on the outer walls of both support rods 6. A baffle 8 is fixedly connected to one end of the support rod 6. Two guide holes 9 are opened through both sides of the movable plate 10. The movable plate 10 is slidably connected to the outer wall of the rubber sleeve 7 through the guide holes 9. Due to the friction between the outer wall of the rubber sleeve 7 and the guide holes 9, the movable plate 10 will not move arbitrarily. A set of mounting slots 11 is provided on both sides of the movable plate 10. A first clamping plate 14 is slidably disposed on the top of the mounting slot 11, and a second clamping plate 16 is slidably disposed on the bottom of the mounting slot 11. A tension spring 17 is provided between the first clamping plate 14 and the second clamping plate 16. The two sets of mounting slots 11 are symmetrically arranged, and several mounting slots 11 in each set are arranged in a linear array at equal intervals. A fixing rod 12 is fixedly connected inside the mounting slot 11. A first slider 13 is slidably connected to the top of the outer wall of the fixing rod 12. One end of the first clamping plate 14 is fixedly connected to one side of the first slider 13. A second slider 15 is slidably connected to the bottom of the outer wall of the fixing rod 12. One end of the second clamping plate 16 is fixedly connected to one side of the second slider 15. Next, one end of the tension spring 17 is fixedly connected to one side of the first slider 13, and the other end is fixedly connected to one side of the second slider 15. The outer wall of the bolt column 18 is located between the first clamping plate 14 and the second clamping plate 16. The inner sides of the first clamping plate 14 and the second clamping plate 16 are provided with guide grooves 21. The bolt column 18 is screwed into the nut 20, so that the bolt head end 19 drives the first clamping plate 14 and the second clamping plate 16 to move closer to the connecting plate 4. At the same time, the guide groove 21 on the first clamping plate 14 and the guide groove 21 on the second clamping plate 16 come into contact. At this time, the moving plate 10 slides on the outer wall of the rubber sleeve 7 on the outer wall of the support rod 6 through the guide hole 9, so that the moving plate 10 moves closer to the connecting plate 4. The first clamping plate 14 and the second clamping plate 16 are located on one side of the bolt head end 19, and the bolt head end 19 side is in contact with the guide groove 21 on one side of the first clamping plate 14 and the guide groove 21 on one side of the second clamping plate 16. In the initial state, one side of the moving plate 10 is in contact with one side of the baffle 8, and the outer wall of the bolt column 18 is located between the first clamping plate 14 and the second clamping plate 16, and the bolt head end 19 side is in contact with one side of the first clamping plate 14 and the second clamping plate 16. Due to the force of the tension spring 17, the first clamping plate 14 and the second clamping plate 16 can clamp the bolt column 18, thereby supporting the bolt column 18 and making it convenient to pre-limit the bolt column 18 to one side of the connecting plate 4, which is convenient for subsequent installation. When one side of the first clamping plate 14 and the second clamping plate 16 contacts one side of a connecting plate 4, the bolt head end 19 is continuously rotated, causing the bolt head end 19 to press against the first clamping plate 14 and the second clamping plate 16. This causes the first clamping plate 14 and the second clamping plate 16 to move outward through the two guide grooves 21, respectively. At this time, the first clamping plate 14 and the second clamping plate 16 respectively drive the first slider 13 and the second slider 15 to slide on the fixed rod 12, thereby increasing the distance between the first slider 13 and the second slider 15. The tension spring 17 is stretched, which facilitates the bolt column 18 to pass through the mounting hole 5 and connect with the nut 20. One side of the bolt head end 19 is tightly fitted with one side of a connecting plate 4, thus completing the connection of the main beam 1 to the secondary beam 3 through the reinforcing plate 2.

[0019] As can be seen from the above, the specific implementation of this utility model is as follows: In the initial state, one side of the moving plate 10 is in contact with one side of the baffle 8, and the outer wall of the bolt column 18 is located between the first clamping plate 14 and the second clamping plate 16, and one side of the bolt head end 19 is in contact with one side of the first clamping plate 14 and the second clamping plate 16. Due to the force of the tension spring 17, the first clamping plate 14 and the second clamping plate 16 can clamp the bolt column 18, thereby supporting the bolt column 18 and pre-limiting the bolt column 18 to one side of the connecting plate 4, which is convenient for subsequent installation. Due to the friction between the outer wall of the rubber sleeve 7 and the guide hole 9, the moving plate 10 will not move arbitrarily. When the main beam 1 and the secondary beam 3 are aligned, the two connecting plates 4 are placed on both sides of the reinforcing plate 2 and the secondary beam 3 respectively, so that the mounting holes 5 of the two connecting plates 4 are aligned. The bolt column 18 is screwed into the nut 20, so that the bolt head end 19 drives the first clamping plate 14 and the second clamping plate 16 to move closer to the connecting plate 4. At the same time, the first The guide groove 21 on one side of clamping plate 14 and the guide groove 21 on one side of second clamping plate 16 come into contact. At this time, the moving plate 10 slides on the outer wall of the rubber sleeve 7 on the outer wall of the support rod 6 through the guide hole 9, so that the moving plate 10 moves closer to the connecting plate 4. When one side of the first clamping plate 14 and the second clamping plate 16 comes into contact with one side of a connecting plate 4, the bolt head end 19 is continuously rotated, so that the bolt head end 19 presses against the first clamping plate 14 and the second clamping plate 16, so that the first clamping plate 14 and the second clamping plate 16 move outward of the bolt head end 19 through the two guide grooves 21 respectively. At this time, the first clamping plate 14 and the second clamping plate 16 respectively drive the first slider 13 and the second slider 15 to slide on the fixed rod 12, so that the distance between the first slider 13 and the second slider 15 is expanded, and the tension spring 17 is stretched, so that the bolt column 18 can pass through the mounting hole 5 and connect with the nut 20. The bolt head end 19 is tightly attached to one side of a connecting plate 4, thus completing the connection of the main beam 1 to the secondary beam 3 through the reinforcing plate 2.
