Description

Technical Field

[0001] This invention relates to the field of connection structure technology, specifically to a fully prefabricated steel structure beam-column joint connection structure. Background Technology

[0002] The beam-column connection nodes of prefabricated steel structures are important connection parts in steel structure construction. Their connection forms are diverse and the connection types are complex, making them a difficult and important aspect of steel structure node design.

[0003] Currently, a high-strength steel structure node is disclosed in patent number "202020102446.6", belonging to the technical field of steel structure node fixing structure. By setting bevels at the upper and lower ends of the square steel tube column base, it is easier to form a molten pool when the square steel tube column base is welded to other steel structure materials. The flowing molten metal can be better concentrated during welding. The square steel tube column base and I-beam are fastened together by bolts, which can be quickly assembled during construction and is convenient and quick for subsequent maintenance. It can reduce the sand holes, internal cracks and slag inclusions generated by welding. By setting a thickened layer on the inner wall surface of the square steel tube column base, the wall thickness of the square steel tube column base can be increased. When the steel tube itself is drilled, the strength of the square steel tube column base is increased. The connection between the thickened layer and the inner surface of the square steel tube column base is all through arc transition, which can reduce the stress concentration problem at the connection between the thickened layer and the square steel tube column base.

[0004] In the prior art provided by the aforementioned patents, existing support beams and I-beams are mostly fixedly connected using multiple bolts. However, some support beams are installed laterally at a high position when installing I-beams. Based on this, after the I-beams are lifted to the corresponding height using lifting equipment, workers still need to manually push the I-beams laterally to align the bolt holes before bolting. Thus, this installation process not only carries certain risks, but also requires the crane to be constantly in operation, resulting in low work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a fully prefabricated steel structure beam-column joint connection structure to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully prefabricated steel structure beam-column joint connection structure, comprising a support beam, an I-beam, and a connector for pre-connecting the support beam and the I-beam. The connector comprises: a boss, which is fixedly connected to the support platform, and the boss has a connected guide groove and a docking groove; a docking block, which is fixedly connected to the I-beam; a pushing mechanism, which includes a slide table elastically slidably connected in the docking groove, the slide table having a vertically elastically slidably connected limit unit, the limit unit including a first limit block and a second limit block connected sequentially from top to bottom, and the length of the first limit block being less than the length of the second limit block; a guide groove is provided in the docking groove, the guide groove including a connected limit groove and a slide groove; a slot is provided on the docking block for inserting and engaging with the first limit block; and a locking mechanism, which is assembled to lock the docking block and is capable of unlocking.

[0007] Preferably, the area of ​​the outer rectangular surface of the guide groove is greater than the area of ​​the inner rectangular surface.

[0008] Preferably, a first elastic telescopic rod is provided between the slide and the docking block. One end of the first elastic telescopic rod is fixedly connected to the docking block, and the other end is fixedly connected to the slide. The process of the first elastic telescopic rod restoring its elastic deformation is used to drive the slide to move along the length direction of the docking groove.

[0009] Preferably, a second elastic telescopic rod is provided between the second limiting block and the slide table. One end of the second elastic telescopic rod is fixedly connected to the second limiting block, and the other end is fixedly connected to the slide table. The process of the second elastic telescopic rod restoring its elastic deformation is used to drive the second limiting block to slide vertically so that the second limiting block is inserted into the limiting groove.

[0010] Preferably, the limiting groove is located at one end of the sliding groove, and the limiting groove and the sliding groove are T-shaped. The sliding groove can slide with the first limiting block, and the limiting groove can engage with the second limiting block.

[0011] Preferably, during the process of the docking block sliding along the guide groove and aligning with the docking groove, the insertion section of the first limiting block is inserted into the slot, and the docking block presses the second limiting block to drive the second limiting block out of the limiting groove until the first limiting block aligns with the sliding groove. Then, the first elastic telescopic rod drives the slide table to move along the length direction of the docking groove until the locking mechanism locks the docking block.

[0012] Preferably, the locking mechanism includes multiple locking units, each locking unit including a locking rod that is elastically slidably connected in the mating groove, the locking end of the locking rod having a first wedge surface, a second wedge surface and a vertical surface, and the mating block having a vertical groove that abuts against the vertical surface.

[0013] Preferably, the locking mechanism further includes an unlocking unit, which includes a spring rod slidably connected to the docking block and an unlocking head fixedly connected to the spring rod. During the process of pulling the spring rod, the unlocking head is used to abut against the first wedge surface of each locking rod to drive the vertical surface away from the vertical groove. Then the docking block abuts against the first wedge surface until each locking rod is removed from the vertical groove.

[0014] Preferably, each locking unit further includes a receiving cavity formed on the inner wall of the docking groove and a first spring disposed in the receiving cavity. One end of the first spring is fixedly connected to the corresponding locking rod, and the other end is fixedly connected to the inner wall of the corresponding receiving cavity. During the process of the docking block being locked by each locking unit, the docking block abuts against the first wedge surface to drive each locking rod to be compressed into the receiving cavity. When each locking rod is aligned with the vertical groove, the process of the first spring restoring its elastic deformation is used to drive the locking rod to be inserted into the corresponding vertical groove.

[0015] Preferably, the support beam and the I-beam are both fixedly connected by connecting beams, and the two connecting beams have multiple corresponding bolt holes, which are then fixedly connected by bolts. In the above technical solution, the present invention provides a fully prefabricated steel structure beam-column joint connection structure. The I-beam is lifted by a crane or other lifting equipment, and aligned with a connecting groove via a guide groove. During the downward sliding alignment process, a first limiting block inserts into a slot, and the connecting block abuts against a second limiting block, causing the second limiting block to disengage from the limiting groove. This allows the first limiting block to align with the sliding groove. Then, under the elastic deformation of the first elastic telescopic rod, the sliding table moves the connecting block fixedly connected to the I-beam, and it is locked by a locking mechanism. The entire process requires no manual assistance, improving the safety of the workers' working environment. Simultaneously, the guide groove drives the I-beam to align, facilitating the subsequent installation of bolts. After locking the connecting block, the I-beam is in a pre-locked state, allowing the crane or other lifting equipment to assist in lifting another I-beam, thereby improving work efficiency.

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-11This invention provides a fully prefabricated steel structure beam-column joint connection structure, including a support beam 1, an I-beam 2, and a connector for pre-connecting the support beam 1 and the I-beam 2. The connector includes a boss 3, a mating block 6, a pushing mechanism 7, and a locking mechanism. The boss 3 is fixedly connected to the support platform, and the boss 3 has a connected guide groove 4 and a mating groove 5. The mating block 6 is fixedly connected to the I-beam 2. The pushing mechanism 7 includes a slide 71 elastically slidably connected within the mating groove 5. A vertical elastic sliding connection with a limiting unit is provided on the 71. The limiting unit includes a first limiting block 72 and a second limiting block 73 connected sequentially from top to bottom. The length of the first limiting block 72 is less than the length of the second limiting block 73. The first limiting block 72 and the second limiting block 73 are convex in shape. A guide groove is provided in the docking groove 5. The guide groove includes a limiting groove 74 and a sliding groove 75 connected together. A slot 76 is provided on the docking block 6 to engage with the first limiting block 72. A locking mechanism is assembled to lock the docking block 6 and unlock it. The limiting groove 74 is located at one end of the sliding groove 75, and the limiting groove 74 and the sliding groove 75 are T-shaped. The sliding groove 75 can slide with the first limiting block 72, and the limiting groove 74 engages with the second limiting block 73. Based on the above, when the second limiting block 73 is in the limiting groove 74, the second limiting block 73 is restricted and will not slide along the slide groove 75. Only when the second limiting block 73 is removed from the limiting groove 74 and the first limiting block 72 is aligned with the slide groove 75 will it move along the length direction of the slide groove 75.

[0021] The area of ​​the outer rectangular surface of the guide groove 4 is larger than the area of ​​the inner rectangular surface. The cross-sectional area of ​​the guide groove 4 is a trapezoid with a wider top and a narrower bottom, and the inner rectangular surface is connected to the docking groove 5. As the docking block 6 moves from the guide groove 4 to the docking groove 5, the four inclined surfaces of the guide groove 4 will straighten the tilted docking block 6 to align it with the docking groove 5.

[0022] A first elastic telescopic rod 9 is provided between the slide table 71 and the docking block 6. One end of the first elastic telescopic rod 9 is fixedly connected to the docking block 6, and the other end is fixedly connected to the slide table 71. The process of the first elastic telescopic rod 9 restoring its elastic deformation is used to drive the slide table 71 to move along the length direction of the docking groove 5. When the I-beam 2 is not installed, the first elastic telescopic rod 9 is a tension spring, but the second limiting block 73 is located in the limiting groove 74, so it will not drive the slide table 71 to slide. In the preferred embodiment, a movable straight groove 13 is provided on the boss 3. The first elastic telescopic rod 9 and the slide table 71 are located in the movable straight groove 13, and the second limiting block 73 will be completely located in the movable straight groove 13 after it is completely disengaged from the limiting groove 74, and will move along the straight direction of the movable straight groove 13 with the slide table 71.

[0023] A second elastic telescopic rod 10 is provided between the second limiting block 73 and the slide table 71. One end of the second elastic telescopic rod 10 is fixedly connected to the second limiting block 73, and the other end is fixedly connected to the slide table 71. The process of the second elastic telescopic rod 10 restoring its elastic deformation is used to drive the second limiting block 73 to slide vertically so that the second limiting block 73 is inserted into the limiting groove 74. When the I-beam 2 is not installed, the second elastic telescopic rod 10 will cause the second limiting block 73 to be located in the limiting groove 74.

[0024] During the process of the docking block 6 sliding along the guide groove 4 and aligning with the docking groove 5, the insertion section of the first limiting block 72 is inserted into the slot 76, and the docking block 6 presses the second limiting block 73 to drive the second limiting block 73 to disengage from the limiting groove 74 until the first limiting block 72 aligns with the sliding groove 75. Then, the first elastic telescopic rod 9 drives the slide table 71 to move along the length direction of the docking groove 5 until the locking mechanism locks the docking block 6.

[0025] Specifically, the I-beam 2 is first lifted using a crane or other lifting equipment. The guide groove 4 guides the I-beam 2 to align with the docking groove 5. During the downward sliding alignment process, the first limiting block 72 inserts into the slot 76, and the docking block 6 abuts against the second limiting block 73, causing the second limiting block 73 to disengage from the limiting groove 74. This allows the first limiting block 72 to align with the sliding groove 75. Then, under the elastic deformation of the first elastic telescopic rod 9, the slide table 71 moves the docking block 6 fixedly connected to the I-beam 2, and the locking mechanism locks it in place. The entire process requires no manual assistance, improving the safety of the workers' working environment. Simultaneously, the guide groove 4 drives the I-beam 2 to align, facilitating the subsequent installation of bolts. After locking the docking block 6, the I-beam 2 is in a pre-locked state, allowing the crane or other lifting equipment to assist in lifting another I-beam 2, further improving work efficiency.

[0026] The locking mechanism includes multiple locking units 8, each including a locking rod 81 that is elastically slidably connected within the mating groove 5. The locking end of the locking rod 81 has a first wedge surface 82, a second wedge surface 83, and a vertical surface 84. The mating block 6 has a vertical groove 85 that abuts against the vertical surface 84. Preferably, the upper inclined end of the first wedge surface 82 is lower than the upper inclined end of the second wedge surface 83, so that the mating block 6 abuts against the second wedge surface 83 during installation to completely disengage the locking rod 81 from the mating groove 5. This facilitates the mating installation of the mating block 6 and subsequent locking by inserting the locking rod 81 into the vertical groove 85.

[0027] The locking mechanism also includes an unlocking unit 11, which comprises a spring rod 111 slidably connected to the docking block 6 and an unlocking head 112 fixedly connected to the spring rod 111. During the pulling of the spring rod 111, the unlocking head 112 abuts against the first wedge surface 82 of each locking rod 81, driving the vertical surface 84 to retract from the vertical groove 85. Then, the docking block 6 abuts against the first wedge surface 82 until each locking rod 81 retracts from the vertical groove 85. It should be noted that the length of the vertical groove 85 is less than the length of the first inclined surface. After the unlocking head 112 abuts against the first wedge surface 82 to disengage the unlocking rod 81 from the movable cavity 14, the upper inclined end of the first wedge surface 82 will simultaneously disengage from the vertical groove 85. Then, the I-beam 2 can be pulled, at which point the vertical surface 84 of the vertical groove 85 abuts against the first wedge surface 82, causing the locking rod 81 to completely disengage from the vertical groove 85. As a preferred embodiment, the spring pull rod 111 is also equipped with a manual pull rod, which is threadedly connected to the I-beam 2. The manual pull rod and the spring pull rod 111 are rotatably connected, while the unlocking head 112 and the docking block 6 are only slidably connected. Thus, when the operator screws on the manual pull rod, the unlocking head 112 slides elastically in a straight line. Based on this, the threaded connection limits the movement of the I-beam 2, ensuring that when the spring pull rod 111 rebounds and passes the locking rod 81, the locking rod 81 resets and locks the docking block 6. In this preferred embodiment, the side of the docking block 6 with the slot 76 does not have a vertical slot 85 for the locking rod 81 to insert into, to avoid interference with the first limiting block 72 during movement.

[0028] Each locking unit 8 includes a receiving cavity 86 formed on the inner wall of the docking groove 5 and a first spring 87 disposed in the receiving cavity 86. One end of the first spring 87 is fixedly connected to the corresponding locking rod 81, and the other end is fixedly connected to the inner wall of the corresponding receiving cavity 86. During the process of the docking block 6 being locked by each locking unit 8, the docking block 6 abuts against the first wedge surface 82 to drive each locking rod 81 to be compressed into the receiving cavity 86. When each locking rod 81 is aligned with the vertical groove 85, the process of the first spring 87 restoring its elastic deformation is used to drive the locking rod 81 to be inserted into the corresponding vertical groove 85.

[0029] Specifically, the docking block 6 has a movable cavity 14, within which the unlocking head 112 moves. Each vertical slot 85 communicates with the movable cavity 14. In the locked state, the first wedge surface 82 is located within the movable cavity 14. Therefore, when the operator manually pulls the spring lever 111, the unlocking head 112 engages with the first wedge surface 82, causing the locking lever 81 to move along the length of the receiving cavity 86 and disengage from the movable cavity 14. Afterward, the I-beam 2 can be directly pulled to disengage from the docking slot 5. Based on the above, the entire unlocking process is simple and convenient.

[0030] Among them, the support beam 1 and the I-beam 2 are both fixedly connected to the connecting beam. Multiple bolt holes are opened on the two connecting beams, and the corresponding bolt holes on the two connecting beams are fixedly connected by bolts.

[0031] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
