Description

Technical Field

[0001] This utility model relates to the technical field of steel structure connectors, and in particular to a steel structure beam end connection unit. Background Technology

[0002] The connection nodes between the ends of steel structure beams and the supporting columns are critical components of the entire steel structure system. The reliability and stability of these connections directly affect the safety performance and service life of the building structure. Currently, the common connection technologies for steel structure beam ends mainly include welding and bolting.

[0003] A search revealed a steel structure beam disclosed in patent document CN202022938377.5. Its structure shows that it mainly adds a fixed end and a locking plate to the end of the steel structure beam. When connected to the external main body or other structures, it relies solely on the mounting plate for bolted positioning.

[0004] However, this bolted connection has obvious shortcomings. In actual use, when the steel structure is subjected to dynamic loads, vibration loads or repeated loads, the bolts are prone to loosening when relying solely on the bolted connection of the mounting plate. When the bolts loosen, the stiffness and load-bearing capacity of the connection will decrease significantly, making it difficult to ensure the stable positioning of the horizontal steel beam, which in turn affects the safety and stability of the entire building structure.

[0005] In summary, existing steel structure beam end connection methods have certain limitations in terms of connection strength, stability, ease of installation, and subsequent maintenance.

[0006] Based on this, the present invention has optimized and improved the existing technology to address the problems existing in the prior art, and hereby proposes a steel structure beam end connection unit to better solve the problems existing in the prior art. Utility Model Content

[0007] To solve one of the aforementioned technical problems, the present invention provides the following technical solution: a steel structure beam end connection unit, comprising a horizontally arranged horizontal beam and a vertically arranged ground-connecting column. The end of the horizontal beam is formed with a U-shaped mounting portion. Both straight sections of the U-shaped mounting portion are installed inside a pressure-bearing connector below it. A vertical sleeve is integrally formed at the bottom center of the pressure-bearing connector. The vertical sleeve is fixedly fitted onto the upper outer wall of the ground-connecting column. The upper end of the ground-connecting column extends through the vertical sleeve and reaches the center bottom of the pressure-bearing connector. A locking lifting component is installed in the central opening of the pressure-bearing connector. Anti-detachment pressure components are installed on both sides of the locking lifting component. The two anti-detachment pressure components are used to cooperate in pressing and positioning the tops of the two straight sections of the U-shaped mounting portion.

[0008] In terms of specific connection principle, the steel structure beam end connection unit in this utility model is mainly used to achieve the support and positioning of the end of the horizontal beam of the steel structure, and to lock it in position on the upper part of the matching ground column. During connection, the horizontal beam is pressed into the corresponding side grooves on the front and rear sides of the top of the pressure-bearing connector by the integrally formed U-shaped mounting part at the end. After the U-shaped mounting part is pressed into place, the anti-detachment pressure parts on both sides are controlled to move down by adjusting the locking lifting part, and the top of the corresponding straight section of the U-shaped mounting part in the corresponding side groove is pressed and positioned, thereby ensuring the pressure and locking of the end of the entire horizontal beam.

[0009] In any of the above embodiments, it is preferred that lower anti-loosening bolts are installed at intervals from top to bottom on the vertical sleeve, and the front and rear ends of each lower anti-loosening bolt pass through the ground-connecting column and the vertical sleeve in the front-rear direction and lock the two in place.

[0010] The through-type lower anti-loosening bolt can better securely install the vertical sleeve on the ground-connecting column and prevent it from loosening.

[0011] In any of the above embodiments, preferably, the pressure-bearing connector includes a pressure-bearing seat fixedly welded to the top of the vertical sleeve, a central blind hole cavity is provided at the bottom center of the pressure-bearing seat for the top of the ground-connecting column to be inserted, the top of the ground-connecting column abuts against the top of the central blind hole cavity, a central opening is provided at the top center of the pressure-bearing seat, and side openings are symmetrically provided on the front and rear sides of the central opening, respectively. The central opening and the side openings are both provided through the pressure-bearing seat in the left and right direction, and the straight section of the U-shaped mounting part is respectively engaged and snapped into the interior of the two side openings.

[0012] The pressure-bearing connector mainly relies on the support structure of the horizontal beam of the steel pressure-bearing seat. When providing support, it relies on the central blind hole cavity at the bottom of the pressure-bearing seat to support the top of the ground column, and at the same time, it is locked and positioned.

[0013] When the straight section of the U-shaped mounting part is inserted into the corresponding side opening, the locking lifting component can drive the anti-detachment pressure components on both sides to rise and fall. At the same time, the corresponding anti-detachment pressure component can be independently controlled to continue to rise and fall. When the anti-detachment pressure component moves down into place, it can directly press the straight section of the U-shaped mounting part downward and insert it into the locking through hole on the corresponding straight section, thereby completing the pressing and anti-detachment positioning of the straight section of the U-shaped mounting part.

[0014] In any of the above embodiments, it is preferred that two upper anti-loosening bolts are installed on the bearing seats on both sides of the central blind hole cavity, and the left and right sides of the two upper anti-loosening bolts pass through the ground connecting column and the bearing seat in the left and right directions respectively, locking and positioning them.

[0015] The upper anti-loosening bolt at the top and the lower anti-loosening bolt at the bottom work together to ensure a stable connection between the pressure seat, the vertical sleeve and the ground-connecting column, while effectively preventing detachment.

[0016] In any of the above embodiments, preferably, the locking lifting component includes a welded helical tube vertically fixed to the top center of the central opening, a central threaded post threaded into the central threaded hole of the welded helical tube, the top of the central threaded post extending to the top of the pressure bearing seat, a horizontal steel plate seat installed on the outer wall of the central threaded post, and central locking nuts threaded into the outer walls of the central threaded post at the upper and lower parts of the horizontal steel plate seat, the two central locking nuts cooperating to clamp the horizontal steel plate seat, and the anti-disengagement pressure component installed in the mounting holes on both sides of the horizontal steel plate seat respectively.

[0017] When adjusting the lifting of the horizontal steel plate seat on the locking lifting component, loosen the two center locking nuts as needed, thereby driving the horizontal steel plate seat to rise and fall to the appropriate position. Then tighten the two center locking nuts. When the horizontal steel plate seat rises and falls, it can drive the anti-detachment pressure components on both sides to rise and fall accordingly.

[0018] In any of the above embodiments, preferably, the anti-detachment pressure component includes a lifting stud that passes through the mounting hole on the horizontal steel plate seat, a pressure seat that is fixedly welded to the bottom of the lifting stud, the bottom of the pressure seat pressing against the top of the straight section of the U-shaped mounting part inside the side opening, a locking column that is fixedly installed at the bottom center of the pressure seat, the bottom of the locking column being inserted into the locking through hole corresponding to the center of the straight section, and a side anti-detachment nut that is threaded onto the outer side wall of the lifting stud at the upper and lower parts of the horizontal steel plate seat, respectively, and the two side anti-detachment nuts cooperate to clamp the horizontal steel plate seat.

[0019] When adjusting the anti-detachment pressure component, the lifting stud can be adjusted in height by loosening the two side anti-detachment nuts as needed. During the adjustment process, the pressure seat can be raised and lowered. When the pressure seat is lowered to the correct position, it will press against the top of the straight section of the U-shaped mounting part. At this time, locking the corresponding side anti-detachment nuts will complete the effective locking. At the same time, since the bottom of the locking column fixedly installed at the bottom center of the pressure seat is inserted into the locking through hole of the straight section, the locking lifting component and the anti-detachment pressure component can be positioned under the positioning action of the central threaded column, thereby restricting the horizontal displacement of the straight section of the U-shaped mounting part.

[0020] In any of the above embodiments, it is preferred that an anti-detachment disc is fixedly welded to the top of both of the lifting studs.

[0021] The anti-detachment disc acts as a top limiter to prevent excessive displacement of the lifting stud.

[0022] In any of the above embodiments, it is preferred that an angle steel connector is installed below the U-shaped mounting portion, the top of the horizontal section of the angle steel connector is pressed against and bolted to the bottom of the U-shaped mounting portion, and one side of the vertical section of the angle steel connector is pressed against and bolted to the corresponding side wall of the pressure bearing seat.

[0023] The angle steel connector further secures the U-shaped mounting part at the end of the horizontal beam to the bearing seat, improving the strength and reliability of the connection.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. Stable and reliable connection: The pressure-bearing connector is stably connected to the ground column through the vertical sleeve, lower anti-loosening bolt and upper anti-loosening bolt, which effectively prevents the connecting parts from loosening, ensures the stability of the overall structure and can withstand various external forces.

[0026] 2. Precise positioning: The top of the ground column is inserted into the central blind hole cavity of the bearing seat, and the U-shaped mounting part at the end of the horizontal beam is engaged with the side opening of the bearing seat to achieve initial positioning; then, with the help of the locking lifting part and the anti-detachment pressure part, the straight section of the U-shaped mounting part is precisely pressed and positioned to prevent detachment, ensuring the accurate positioning of the end of the horizontal beam.

[0027] 3. Easy adjustment: The central threaded column of the locking lifting component is threaded with the welded helical tube, which can adjust the height of the horizontal steel plate seat and the anti-detachment pressure component; the lifting column of the anti-detachment pressure component can be finely adjusted individually, which makes it convenient to flexibly adjust the position of each component according to actual needs.

[0028] 4. Enhanced connection strength: The angle steel connector further secures the U-shaped mounting part at the end of the horizontal beam to the bearing seat, sharing the load transmitted by the horizontal beam, enhancing the connection strength between the U-shaped mounting part and the bearing seat, and improving the stability of the entire connection unit.

[0029] 5. Excellent anti-detachment performance: The locking post at the bottom of the anti-detachment pressure component is inserted into the locking through hole of the straight section of the U-shaped mounting part. Combined with the tight fit of each connecting component, it effectively restricts the horizontal displacement of the U-shaped mounting part, prevents the connection from falling off, and improves connection safety.

Detailed Implementation

[0042] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-10 As shown in the image.

[0043] Example 1: A steel structure beam end connection unit includes a horizontally arranged horizontal beam 1 and a vertically arranged ground-connecting column 2. The end of the horizontal beam 1 is formed with a U-shaped mounting part 3. The two straight sections of the U-shaped mounting part 3 are installed inside the pressure-bearing connector below it. A vertical sleeve 4 is integrally formed at the bottom center of the pressure-bearing connector. The vertical sleeve 4 is fixedly sleeved on the upper outer side wall of the ground-connecting column 2. The upper end of the ground-connecting column 2 passes through the vertical sleeve 4 and extends to the center bottom of the pressure-bearing connector. A locking lifting part is installed in the center opening 8 of the pressure-bearing connector. Anti-detachment pressure parts are installed on both sides of the locking lifting part. The two anti-detachment pressure parts are used to cooperate to press and position the tops of the two straight sections of the U-shaped mounting part 3.

[0044] The steel structure beam end connection unit in this utility model is mainly used to support and position the end of the horizontal beam 1 of the steel structure, and lock it in place on the upper part of the cooperating ground column 2. During connection, the horizontal beam 1 is pressed into the corresponding side grooves on the front and rear sides of the top of the pressure-bearing connector by the integrally formed U-shaped mounting part 3 at the end. After the U-shaped mounting part 3 is pressed into place, the anti-detachment pressure members on both sides are controlled to move down by adjusting the locking lifting member, and the top of the corresponding straight section of the U-shaped mounting part 3 in the corresponding side groove is pressed and positioned, thereby ensuring the pressure and locking of the end of the entire horizontal beam 1. Specifically, the horizontal beam 1 is initially positioned above the ground column 2 by cooperating with the pressure-bearing connector through the U-shaped mounting part 3 at the end. The pressure-bearing connector plays a key role in bearing and connecting. The vertical sleeve 4 connects the pressure-bearing connector to the ground column 2, and the U-shaped mounting part 3 is finally fixed by the locking lifting member and the anti-detachment pressure member.

[0045] The steel structure beam end connection unit in this utility model is mainly used to achieve the support and positioning of the end of the horizontal beam 1 of the steel structure, and to lock it in position on the upper part of the matching ground column 2. During the connection, the horizontal beam 1 is pressed into the corresponding side grooves on the front and rear sides of the top of the pressure-bearing connector by the integrally formed U-shaped mounting part 3 at the end. After the U-shaped mounting part 3 is pressed into place, the anti-detachment pressure parts on both sides are controlled to move down by adjusting the locking lifting part, and the top of the corresponding straight section of the U-shaped mounting part 3 in the corresponding side groove is pressed and positioned, thereby ensuring the pressure and locking of the end of the entire horizontal beam 1.

[0046] In any of the above embodiments, it is preferred that lower anti-loosening bolts 5 are installed at intervals from top to bottom on the vertical sleeve 4, and the front and rear ends of each lower anti-loosening bolt 5 pass through the ground-connecting column 2 and the vertical sleeve 4 in the front-back direction and lock the two in place.

[0047] When installing the lower anti-loosening bolt 5, pass the bolt through the corresponding holes of the grounding post 2 and the vertical sleeve 4, and then tighten the nut. The tightening force of the bolt makes the grounding post 2 and the vertical sleeve 4 fit tightly together, and when subjected to external force, it restricts the relative displacement between the two, ensuring that the vertical sleeve 4 is securely fitted onto the grounding post 2.

[0048] The through-type lower anti-loosening bolt 5 can better securely install the vertical sleeve 4 on the ground column 2, preventing it from loosening.

[0049] In any of the above embodiments, it is preferred that the pressure-bearing connector includes a pressure-bearing seat 6 fixedly welded to the top of the vertical sleeve 4, a central blind hole cavity 7 is provided at the bottom center of the pressure-bearing seat 6 for the top of the ground connecting column 2 to be inserted, the top of the ground connecting column 2 abuts against the top of the central blind hole cavity 7, a central opening 8 is provided at the top center of the pressure-bearing seat 6, and side openings 9 are symmetrically provided on the front and rear sides of the central opening 8, the central opening 8 and the side openings 9 are both provided through the pressure-bearing seat 6 in the left and right direction, and the straight section of the U-shaped mounting part 3 is respectively engaged and snapped into the interior of the two side openings 9.

[0050] During installation, the top of the ground-connecting column 2 is inserted into the central blind hole 7 of the bearing seat 6, serving as initial positioning and support. The straight section of the U-shaped mounting part 3 at the end of the horizontal beam 1 is engaged with the side opening 9 of the bearing seat 6, providing a foundation for subsequent positioning and fixing. The structural design of the bearing seat 6 enables it to withstand the load transmitted by the horizontal beam 1 and transfer the load to the ground-connecting column 2 through the central blind hole 7.

[0051] The pressure-bearing connector mainly relies on the support structure of the horizontal beam 1 of the steel pressure-bearing seat 6. When providing support, it is supported on the top of the ground column 2 by the central blind hole cavity 7 at the bottom of the pressure-bearing seat 6, and is locked and positioned at the same time.

[0052] When the straight section of the U-shaped mounting part 3 is inserted into the corresponding side opening 9, the anti-detachment pressure members on both sides can be raised and lowered by the screw-locking lifting member. At the same time, the corresponding anti-detachment pressure member can be independently controlled to continue to rise and fall. When the anti-detachment pressure member moves down into place, it can directly press the straight section of the U-shaped mounting part 3 downward and insert it into the locking through hole 18 on the corresponding straight section, thereby completing the pressing and anti-detachment positioning of the straight section of the U-shaped mounting part 3.

[0053] The weight of the horizontal beam 1 and other loads are transferred to the bearing seat 6 through the U-shaped mounting part 3. The bearing seat 6 uses its own structural strength and rigidity to bear these loads. The central blind hole cavity 7 fits tightly with the top of the ground-connecting column 2, which not only provides support but also limits the relative displacement between the bearing seat 6 and the ground-connecting column 2 to a certain extent. Combined with other locking components, a reliable connection between the two is achieved.

[0054] In any of the above embodiments, it is preferred that two upper anti-loosening bolts 10 are installed on the pressure-bearing seats 6 on both sides of the central blind hole cavity 7, and the left and right sides of the two upper anti-loosening bolts 10 pass through the ground connecting column 2 and the pressure-bearing seat 6 respectively in the left and right direction, and lock and position them.

[0055] The upper anti-loosening bolt 10 located at the top and the lower anti-loosening bolt 5 located at the bottom can cooperate to enable the bearing seat 6 and the vertical sleeve 4 to achieve a stable connection with the ground-connecting column 2, while effectively preventing detachment.

[0056] In any of the above embodiments, preferably, the locking lifting component includes a welded threaded tube 11 vertically fixed to the top center of the central opening 8. A central threaded post 12 is threaded into the central threaded hole of the welded threaded tube 11, with the top of the central threaded post 12 extending to the top of the pressure seat 6. A horizontal steel plate seat 13 is installed on the outer wall of the central threaded post 12. Central locking nuts 14 are threaded into the outer walls of the central threaded post 12 at the upper and lower parts of the horizontal steel plate seat 13. The two central locking nuts 14 cooperate to clamp the horizontal steel plate seat 13. The anti-detachment pressure component is installed in the mounting holes on both sides of the horizontal steel plate seat 13. When it is necessary to adjust the height of the anti-detachment pressure component, the central locking nuts 14 are loosened first to release the clamping force on the horizontal steel plate seat 13. Then rotate the central threaded post 12. Since the central threaded post 12 and the welded threaded tube 11 are threadedly fitted, the rotation of the central threaded post 12 will cause it to move up and down inside the welded threaded tube 11, thereby driving the horizontal steel plate seat 13 to rise and fall. The rising and falling of the horizontal steel plate seat 13 will also drive the anti-detachment pressure components installed on both sides of it to rise and fall synchronously. After adjusting to the appropriate position, tighten the central locking nut 14 to fix the horizontal steel plate seat 13 in the current position.

[0057] When adjusting the horizontal steel plate seat 13 on the locking lifting component, the two center locking nuts 14 are loosened as needed, thereby driving the horizontal steel plate seat 13 to rise and fall to a suitable position. Then, the two center locking nuts 14 are locked, so that the anti-detachment pressure components on both sides can follow the rise and fall when the horizontal steel plate seat 13 rises and falls.

[0058] Example 2: Compared with Example 1, this example also includes the following technical features:

[0059] In any of the above embodiments, preferably, the anti-detachment pressure component includes a lifting stud 15 that passes through a mounting hole on the horizontal steel plate seat 13. A pressure seat 16 is fixedly welded to the bottom of the lifting stud 15. The bottom of the pressure seat 16 presses against the top of the straight section of the U-shaped mounting part 3 inside the side opening 9. A locking column 17 is fixedly installed at the center of the bottom of the pressure seat 16. The bottom of the locking column 17 is inserted into the locking through hole 18 corresponding to the center of the straight section. A side anti-detachment nut 19 is threaded onto the outer side wall of the lifting stud 15 at the upper and lower parts of the horizontal steel plate seat 13, respectively. The two side anti-detachment nuts 19 cooperate to clamp the horizontal steel plate seat 13. Based on embodiment 1, when it is necessary to fine-tune the position of the anti-detachment pressure component, the side anti-detachment nuts 19 are loosened and the lifting stud 15 is rotated. Since the mounting hole of the lifting stud 15 is threadedly fitted with the horizontal steel plate seat 13, rotating the lifting stud 15 can move it up and down, thereby driving the pressure seat 16 to rise and fall. When the pressure seat 16 descends to press the top of the straight section of the U-shaped mounting part 3, and the locking column 17 is inserted into the locking through hole 18 of the straight section, tighten the side anti-loosening nut 19 to fix the lifting stud 15 in the current position, achieving more precise positioning and anti-loosening.

[0060] When adjusting the anti-detachment pressure component, the two side anti-detachment nuts 19 can be loosened to adjust the height of the lifting stud 15 as needed. During the adjustment process, the pressure seat 16 can be raised and lowered. When the pressure seat 16 is lowered to the correct position, it will press against the top of the straight section of the U-shaped mounting part 3. At this time, locking the corresponding side anti-detachment nuts 19 can effectively lock the part. At the same time, since the bottom of the locking column 17 fixedly installed at the bottom center of the pressure seat 16 is inserted into the locking through hole 18 of the straight section, the locking lifting component and the anti-detachment pressure component can be positioned under the positioning action of the central threaded column 12, thereby restricting the horizontal displacement of the straight section of the U-shaped mounting part 3.

[0061] In any of the above embodiments, it is preferred that an anti-detachment disc 20 is fixedly welded to the top of both of the lifting studs 15.

[0062] The anti-detachment disc 20 acts as a top limit to prevent the lifting stud 15 from shifting excessively.

[0063] In any of the above embodiments, it is preferred that an angle steel connecting seat 21 is installed below the U-shaped mounting part 3, the top of the horizontal section of the angle steel connecting seat 21 is pressed against and bolted to the bottom of the U-shaped mounting part 3, and one side of the vertical section of the angle steel connecting seat 21 is pressed against and bolted to the corresponding side wall of the pressure bearing seat 6.

[0064] The angle steel connector 21 further secures the U-shaped mounting portion 3 at the end of the horizontal beam 1 to the bearing seat 6, improving the strength and reliability of the connection. When installing the angle steel connector 21, its horizontal section is fixed to the bottom of the U-shaped mounting portion 3, and its vertical section is fixed to the side wall of the bearing seat 6, respectively, using bolts. When the connection unit bears a load, the angle steel connector 21 can share a portion of the load transmitted by the horizontal beam 1, enhancing the connection strength between the U-shaped mounting portion 3 and the bearing seat 6, improving the stability of the entire connection unit, and making the connection more robust and reliable.

[0065] Specific working principle: First, align the U-shaped mounting part 3 at the end of the horizontal beam 1 with the side opening 9 on the pressure-bearing connector, insert and press it into place. At this time, the top of the ground-connecting column 2 is inserted into the central blind hole cavity 7 at the bottom of the pressure seat 6, initially achieving the positioning of the horizontal beam 1, the pressure-bearing connector, and the ground-connecting column 2. Next, according to actual needs, loosen the central locking nut 14 on the locking lifting component, rotate the central threaded column 12, and drive the horizontal steel plate seat 13 and the anti-detachment pressure components installed on both sides to descend. The lifting stud 15 of the anti-detachment pressure component will descend with the horizontal steel plate seat 13, and the bottom of the pressure seat 16 will gradually approach the top of the straight section of the U-shaped mounting part 3. When the pressure seat 16 descends into place, it presses the top of the straight section of the U-shaped mounting part 3 tightly, and at the same time, the locking column 17 at the bottom center of the pressure seat 16 is inserted into the corresponding locking through hole 18 at the center of the straight section. Then, tighten the center locking nut 14 and the side anti-loosening nut 19 respectively to fix the horizontal steel plate seat 13 and the lifting stud 15, completing the pressure positioning and anti-loosening positioning of the U-shaped mounting part 3. During the entire connection process, the lower anti-loosening bolt 5 and the upper anti-loosening bolt 10 firmly connect the vertical sleeve 4, the pressure seat 6 and the ground column 2 from the upper and lower positions respectively, preventing them from loosening. The angle steel connecting seat 21 further strengthens the connection between the U-shaped mounting part 3 and the pressure seat 6, ensuring that the entire connection unit remains stable when subjected to various external forces.
