Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel structure beam connector. Background Technology

[0002] Steel structure beams and columns are a common building structure, possessing advantages such as high strength, lightweight, and earthquake resistance, and are widely used in industrial, civil, and bridge construction fields. The main connection methods for steel structure beams and columns include welding, bolting, and riveting. Among these, welded connections offer advantages such as high structural rigidity, strong load-bearing capacity, and aesthetically pleasing appearance, while bolted and riveted connections offer advantages such as simple construction, low cost, easy disassembly, and convenient maintenance.

[0003] Patent CN217734346U discloses a beam connector for prefabricated steel structures: It includes a main back plate, with first connecting side plates bent to one side on both the upper and lower edges of the main back plate; a second connecting side plate bent to one side on one side of the main back plate, the second connecting side plate facing the same direction as the first connecting side plate; and auxiliary connecting side plates bent to one side on both the upper and lower edges of the second connecting side plate, facing the second connecting side plate. The standardized beam-to-beam connection improves efficiency and reduces costs throughout the design, production, and installation process. The pre-production of the connectors in batches effectively reduces production costs and improves product quality, shortening the processing time of the steel structure in the factory. On-site installation is entirely bolted, facilitating installation and reducing the technical requirements for workers, effectively improving on-site installation efficiency.

[0004] In practical applications, the aforementioned existing technology requires two beam connectors to connect the I-beam main beam and the I-beam auxiliary beam. Furthermore, the two beam connectors must be connected and fixed to the I-beam main beam before the I-beam auxiliary beam can be installed. Otherwise, the two beam connectors cannot provide support and positioning for the I-beam auxiliary beam, which requires the I-beam auxiliary beam to be suspended and wait or its installation to be delayed. This is not only inconvenient for quickly connecting the I-beam main beam and the I-beam auxiliary beam, but also detrimental to construction safety. In view of this, we propose a steel structure beam connector. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure beam connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel structure beam connector includes a main connecting plate installed on the inner wall of an I-beam. The main connecting plate is detachably connected to the I-beam via four first locking bolts. Two secondary connecting plates are symmetrically arranged on the right side of the main connecting plate, positioned near the middle of the right side of the main connecting plate. These two secondary connecting plates are detachably connected to the ends of an I-beam via two second locking bolts. The opposite sides of the two secondary connecting plates are respectively abutted against the front and rear sides of the inner wall of the I-beam. The ends of the I-beam are inserted between the two secondary connecting plates. L-shaped support plates are provided at the top of the opposite sides of the two secondary connecting plates. The top of the horizontal plate of the L-shaped support plate is aligned with the top of the inner wall of the I-beam. The two L-shaped support plates, together with the two auxiliary connecting plates, can support the ends of the I-beam auxiliary beam. When using this steel structure beam connector to connect the I-beam main beam and the I-beam auxiliary beam, first, the left side of the main connecting plate is attached to the side of the inner wall of the I-beam main beam, so that part of the steel structure beam connector is stuck inside the I-beam main beam. Then, the end of the I-beam auxiliary beam is inserted between the two auxiliary connecting plates. The two L-shaped support plates can support the I-beam auxiliary beam, thereby initially positioning the relative positions of the I-beam main beam and the I-beam auxiliary beam, which makes it easy for workers to quickly complete the docking of the I-beam main beam and the I-beam auxiliary beam. After that, tightening the first locking bolt and the second locking bolt will complete the connection of the steel structure beam.

[0008] Preferably, the main connecting plate and the two auxiliary connecting plates are integrally formed structures and are made of steel to ensure the overall strength of the main connecting plate and the two auxiliary connecting plates, thereby ensuring the stability of the connection between the I-beam main beam and the I-beam auxiliary beam.

[0009] Preferably, the main connecting plate has a circular hole a on the right side and near the four corners for the first locking bolt to pass through. The threaded end of the first locking bolt passes through the circular hole a and the side of the inner wall of the I-shaped auxiliary beam in sequence and is threadedly connected to the first clamping nut. The first clamping nut cooperates with the first locking bolt to lock the main connecting plate in the I-shaped auxiliary beam.

[0010] Preferably, a hexagonal first limiting frame is provided on the right side of the main connecting plate at the position of each of the four circular holes a. The hexagonal bolt head of the first locking bolt is positioned within the hexagonal first limiting frame. When the operator tightens the first clamping nut, the position of the first locking bolt can be fixed, which is beneficial for the first clamping nut to lock the first locking bolt.

[0011] Preferably, two circular holes b are provided on the front side and near the right side of the sub-connecting plate, arranged symmetrically in an upper and lower position. The threaded end of the second locking bolt passes through the circular hole b of the front sub-connecting plate, the side of the inner wall of the I-shaped auxiliary beam, and the circular hole b of the rear sub-connecting plate in sequence, and is threadedly connected to the second clamping nut. The second clamping nut cooperates with the second locking bolt to lock the end of the I-shaped auxiliary beam between the two sub-connecting plates.

[0012] Preferably, a hexagonal second limiting frame is provided on the front side of the sub-connecting plate at the position of the two circular holes b. The hexagonal bolt head of the second locking bolt is positioned within the hexagonal second limiting frame. When the operator tightens the second clamping nut, the position of the second locking bolt can be fixed, which is beneficial for the second clamping nut to lock the second locking bolt.

[0013] Preferably, a triangular reinforcing plate is vertically provided in the middle of the opposite sides of the two auxiliary connecting plates, and the left side of the two triangular reinforcing plates is welded to the right side of the main connecting plate, thereby further improving the overall strength of the main connecting plate and the auxiliary connecting plates.

[0014] Preferably, the bottom of the opposite sides of the two auxiliary connecting plates are vertically provided with L-shaped reinforcing plates, and the left sides of the two L-shaped reinforcing plates are welded to the right side of the main connecting plate. The bottom of the L-shaped reinforcing plates is in contact with the bottom of the inner wall of the I-beam main beam and the I-beam auxiliary beam. Since the top of the I-beam main beam and the I-beam auxiliary beam will also be equipped with weights, the L-shaped reinforcing plates can strengthen the longitudinal support strength of the auxiliary connecting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When using this steel structure beam connector to connect the I-beam main beam and the I-beam auxiliary beam, first, align the left side of the main connecting plate with the side of the inner wall of the I-beam main beam, so that part of the steel structure beam connector is stuck inside the I-beam main beam. Then, insert the end of the I-beam auxiliary beam between the two auxiliary connecting plates. The two L-shaped support plates can support the I-beam auxiliary beam, thereby initially positioning the relative positions of the I-beam main beam and the I-beam auxiliary beam, which facilitates the workers to quickly complete the docking of the I-beam main beam and the I-beam auxiliary beam. After that, tighten the first locking bolt and the second locking bolt to complete the connection of the steel structure beam.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] A steel structure beam connector includes a main connecting plate 1 installed on the inner wall of an I-beam. The main connecting plate 1 is detachably connected to the I-beam via four first locking bolts 8. Two auxiliary connecting plates 2 are symmetrically arranged on the right side of the main connecting plate 1, located near the middle of the right side of the main connecting plate 1. The two auxiliary connecting plates 2 are detachably connected to the ends of an I-beam via two second locking bolts 9. The opposite sides of the two auxiliary connecting plates 2 are respectively abutted against the front and rear sides of the inner wall of the I-beam. The ends of the I-beam are inserted between the two auxiliary connecting plates 2. L-shaped support plates 3 are provided on the top of the opposite sides of the two auxiliary connecting plates 2. The top of the horizontal plate of the L-shaped support plate 3 is aligned with the top of the inner wall of the I-beam. The two L-shaped support plates 3, together with the two auxiliary connecting plates 2, can support the ends of the I-shaped auxiliary beam. When using this steel structure beam connector to connect the I-shaped main beam and the I-shaped auxiliary beam, first, the left side of the main connecting plate 1 is attached to the side of the inner wall of the I-shaped main beam, so that part of the steel structure beam connector is stuck in the I-shaped main beam. Then, the end of the I-shaped auxiliary beam is inserted between the two auxiliary connecting plates 2. The two L-shaped support plates 3 can support the I-shaped auxiliary beam, thereby initially positioning the relative position of the I-shaped main beam and the I-shaped auxiliary beam, which makes it easy for the workers to quickly complete the docking of the I-shaped main beam and the I-shaped auxiliary beam. After that, tightening the first locking bolt 8 and the second locking bolt 9 will complete the connection of the steel structure beam.

[0029] In this embodiment, the main connecting plate 1 and the two auxiliary connecting plates 2 are integrally formed structures and are made of steel to ensure the overall strength of the main connecting plate 1 and the two auxiliary connecting plates 2, thereby ensuring the stability of the connection between the I-beam main beam and the I-beam auxiliary beam.

[0030] Specifically, the main connecting plate 1 has circular holes a10 on its right side and near the four corners for the first locking bolt 8 to pass through. The threaded end of the first locking bolt 8 passes through the circular hole a10 and the side of the inner wall of the I-shaped auxiliary beam in sequence and is threadedly connected to the first clamping nut 80. The first clamping nut 80 cooperates with the first locking bolt 8 to lock the main connecting plate 1 in the I-shaped auxiliary beam.

[0031] Furthermore, a hexagonal first limiting frame 6 is provided on the right side of the main connecting plate 1 at the position of the four circular holes a10. The hexagonal bolt head of the first locking bolt 8 is positioned in the hexagonal first limiting frame 6. When the operator tightens the first clamping nut 80, the position of the first locking bolt 8 can be fixed, which is conducive to the first clamping nut 80 locking the first locking bolt 8.

[0032] Furthermore, two circular holes b20 are provided on the front side and near the right side of the sub-connecting plate 2, arranged symmetrically in an upper and lower position. The threaded end of the second locking bolt 9 passes through the circular hole b20 of the front sub-connecting plate 2, the side of the inner wall of the I-shaped auxiliary beam, and the circular hole b20 of the rear sub-connecting plate 2 in sequence, and is threadedly connected to the second clamping nut 90. The second clamping nut 90 cooperates with the second locking bolt 9 to lock the end of the I-shaped auxiliary beam between the two sub-connecting plates 2.

[0033] Furthermore, a hexagonal second limiting frame 7 is provided on the front side of the front auxiliary connecting plate 2 at the position of the two circular holes b20. The hexagonal bolt head of the second locking bolt 9 is positioned in the hexagonal second limiting frame 7. When the operator tightens the second clamping nut 90, the position of the second locking bolt 9 can be fixed, which is conducive to the second clamping nut 90 locking the second locking bolt 9.

[0034] Furthermore, triangular reinforcing plates 5 are vertically provided in the middle of the opposite sides of the two secondary connecting plates 2, and the left sides of the two triangular reinforcing plates 5 are welded to the right side of the main connecting plate 1, further improving the overall strength of the main connecting plate 1 and the secondary connecting plates 2.

[0035] Furthermore, L-shaped reinforcing plates 4 are vertically provided at the bottom of the opposite sides of the two secondary connecting plates 2. The left sides of the two L-shaped reinforcing plates 4 are welded to the right side of the main connecting plate 1. The bottom of the L-shaped reinforcing plates 4 is in contact with the bottom of the inner wall of the I-beam main beam and the I-beam auxiliary beam. Since the top of the I-beam main beam and the I-beam auxiliary beam will also be equipped with weights, the L-shaped reinforcing plates 4 can strengthen the longitudinal support strength of the secondary connecting plates 2.

[0036] In this embodiment, when using the steel structure beam connector, the operator first aligns the left side of the main connecting plate 1 with the side of the inner wall of the I-beam, so that part of the steel structure beam connector is locked inside the I-beam. Then, the end of the I-beam auxiliary beam is inserted between the two auxiliary connecting plates 2 until the end of the I-beam auxiliary beam is aligned with the side of the I-beam main beam. At this point, the two L-shaped support plates 3 support the I-beam auxiliary beam, thus initially positioning the relative positions of the I-beam main beam and the I-beam auxiliary beam, facilitating the operator to quickly connect the I-beam main beam and the I-beam auxiliary beam. Afterward, the operator sequentially inserts the threaded end of the first locking bolt 8 through the circular hole a. The mounting holes pre-drilled on the inner wall side of the I-beam auxiliary beam 10 are passed through, and the first clamping nut 80 is threadedly connected to the first locking bolt 8, so that the first clamping nut 80 locks the main connecting plate 1 inside the I-beam auxiliary beam. Then, the threaded end of the second locking bolt 9 passes through the circular hole b20 of the front auxiliary connecting plate 2, the mounting hole pre-drilled on the inner wall side of the I-beam auxiliary beam, and the circular hole b20 of the rear auxiliary connecting plate 2 in sequence, and is threadedly connected to the second locking bolt 9 with the second clamping nut 90, so that the second clamping nut 90 locks the end of the I-beam auxiliary beam between the two auxiliary connecting plates 2, thereby realizing the connection between the I-beam main beam and the I-beam auxiliary beam.
