Description

Technical Field

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

[0002] When a construction project needs to span a large distance, a single I-beam cannot meet the length requirements, and the I-beams need to be extended by splicing to form a continuous beam structure.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN213204479U discloses a steel structure connector for buildings. In use, after initially butt-joining the two ends of the I-beams or other connecting parts, the snap-fit ​​connector is fused inwards and passed through the connecting hole. A screw is then inserted into the inner surface of the snap-fit ​​connector to prop it up, ensuring that the U-shaped groove is engaged with the inner wall of the connecting hole. The flange column is rotated to screw the thread onto the inner surface of the threaded ring, thus quickly assembling and temporarily fixing the temporary fastener. The two I-beams are connected by a connecting plate. To ensure connection strength, the ends of the two I-beams abut against each other, which fixes the length of the steel beam after butt-jointing. During construction, it is impossible to make minor adjustments according to assembly requirements, and the length accuracy of the cut individual I-beams is required to be high. Furthermore, the I-beams undergo thermal expansion and contraction with temperature changes, which may cause bending or twisting of the I-beams, especially in long-span structures where this deformation is more pronounced.

[0004] Therefore, it is necessary to design a building steel structure connector that can make minor adjustments to the length after splicing, reduce the length accuracy requirements for cutting I-beams, and prevent I-beams from bending due to thermal expansion and contraction to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a building steel structure connector that allows for minute adjustments to the length of the spliced ​​structure, reducing the length accuracy requirements for cutting I-beams and preventing the I-beams from bending due to thermal expansion and contraction.

[0006] The technical solution of this utility model is as follows: a building steel structure connector, including a first profile, a second profile, and a connector. The connector has a slot that matches the first profile and the second profile through it. The web plates of the first profile and the second profile near the connector are evenly provided with waist-shaped holes. The long axis of the waist-shaped holes matches the extension direction of the slots. The connector has a round hole that matches the waist-shaped holes. The round hole and the corresponding waist-shaped hole are fitted with bolt and nut mechanisms. The web plate of the first profile near the connector has a slot. The web plate of the second profile near the connector has a sliding plate that slides inside the slot.

[0007] Furthermore, the first profile and the second profile are I-beams of the same specifications, and the connector is an H-shaped structure that matches the first profile and the second profile. Both ends of the connector are provided with side ribs that are integral with it.

[0008] Furthermore, the side ribs are flush with both sides of the connector, and the connector is detachably and fixedly fitted with partitions on both sides, with the partitions being sealed to the side ribs and the connector.

[0009] Furthermore, a transparent observation window is provided on the partition.

[0010] Furthermore, the transparent observation window is a transparent acrylic plate.

[0011] Furthermore, each end of the connector is fixedly provided with two guide blocks corresponding to the two sides of the web of the first profile and the second profile, respectively, and the end of the guide block is provided with a guide slope.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, the ends of the first profile and the second profile are respectively inserted into the interior of the connector through the two ends of the slot, and then the first profile, the second profile and the connector are assembled and fixed by the bolt and nut mechanism. The docking construction of the first profile and the second profile can be completed quickly without welding.

[0014] (2) The bolt and nut mechanism assembled inside the circular hole of the connector matches the waist-shaped hole of the first profile and the second profile. During installation, the position of the first profile and the second profile relative to the connector can be finely adjusted through the waist-shaped hole, thereby finely adjusting the length of the steel beam after docking, adapting to the length requirements of installation, and reducing the length accuracy requirements of cutting the I-beam.

[0015] (3) After installation, the first profile and the second profile will undergo thermal expansion and contraction when the temperature changes, resulting in changes in their length. The first profile and the second profile are reserved with space through the waist-shaped hole, so that the ends of the first profile and the second profile can move along the slot inside the connector, releasing the stress generated by thermal expansion and contraction of the first profile and the second profile, and preventing the first profile and the second profile from bending or twisting.

[0016] (4) The first profile and the second profile are slidably connected inside the connector by the cooperation of the sliding plate and the slot. On the one hand, this does not affect the length fine adjustment and stress release, and on the other hand, it can increase the connection area between the first profile and the second profile and improve the connection strength.

[0023] like Figures 1 to 4 As shown, the building steel structure connector includes a first profile 2, a second profile 5, and a connector 1. The connector 1 has a through slot 11 that matches the first profile 2 and the second profile 5. The first profile 2 and the second profile 5 have evenly spaced oblong holes 21 on their webs near the connector 1. The long axis of the oblong holes 21 matches the extension direction of the slot 11. The connector 1 has a round hole 12 that matches the oblong holes 21. Bolt and nut mechanisms 4 are assembled inside the round hole 12 and the corresponding oblong hole 21. A slot 22 is provided on the web of the first profile 2 near the connector 1. A sliding plate 51 is provided on the web of the second profile 5 near the connector 1, and the sliding plate 51 is slidably disposed inside the slot 22. In this embodiment, the ends of the first profile 2 and the second profile 5 are respectively inserted into the connector 1 through the two ends of the slot 11, and then the first profile 2, the second profile 5 and the connector 1 are assembled and fixed by the bolt and nut mechanism 4. The docking construction of the first profile 2 and the second profile 5 can be quickly completed without welding. Connector 1 The bolt and nut mechanism 4, installed inside the circular hole, matches the slotted holes 21 of the first profile 2 and the second profile 5. During installation, the slotted holes 21 allow for fine-tuning of the positions of the first profile 2 and the second profile 5 relative to the connector 1, thereby fine-tuning the length of the steel beam after docking to meet installation length requirements and reduce the length accuracy requirements for cutting the I-beams. Furthermore, after installation, the first profile 2 and the second profile 5 will experience thermal expansion and contraction due to temperature changes, causing length changes. The slotted holes 21 further facilitate this adjustment. The hole 21 provides space so that the ends of the first profile 2 and the second profile 5 can move along the slot 11 inside the connector 1, releasing the stress generated by the thermal expansion and contraction of the first profile 2 and the second profile 5, and preventing the first profile 2 and the second profile 5 from bending or twisting; the first profile 2 and the second profile 5 are slidably connected inside the connector 1 by the sliding plate 51 cooperating with the slot 22, which does not affect the length fine adjustment and stress release, and can increase the connection area between the first profile 2 and the second profile 5, thereby improving the connection strength.

[0024] In some embodiments, the first profile 2 and the second profile 5 are I-beams of the same specification. The connector 1 is an H-shaped structure that matches the first profile 2 and the second profile 5. The slot 11 inside the connector 1 is an H-shaped slot that matches the first profile 2 and the second profile 5. The first profile 2 and the second profile 5 can be slidably inserted into the slot 11. Both ends of the connector 1 are provided with side ribs 13 that are integral with it. The side ribs 13 are integral with the connector 1 and can connect the strength of both sides of the connector 1 through the side ribs 13.

[0025] In some embodiments, such as Figure 4As shown, the side rib plate 13 is flush with both sides of the connector 1. The connector 1 has a partition plate 6 detachably fixedly mounted on both sides. The partition plate 6 is sealed to the side rib plate 13 and the connector 1. The partition plate 6 can reduce the amount of rainwater entering from both sides of the connector 1 and coming into contact with the bolt and nut mechanism 4, thus reducing the erosion of the bolt and nut mechanism 4 by rainwater. Specifically, the inner side of the partition plate 6 is provided with a sealing ring corresponding to the side of the side rib plate 13 and the side of the connector 1. The sealing ring further improves the sealing performance between the partition plate 6 and the side of the side rib plate 13 and the side of the connector 1, reducing the erosion of the bolt and nut mechanism 4 by rainwater.

[0026] In some embodiments, a transparent observation window 7 is provided on the partition 6. The connection status of the bolt and nut mechanism 4 inside can be inspected through the transparent observation window 7 without disassembling the partition 6, which facilitates maintenance and repair. When loosening occurs, it can be detected in time, and the partition 6 can be removed to tighten the loose bolt and nut mechanism 4. Specifically, the transparent observation window 7 is a transparent acrylic plate.

[0027] In some embodiments, two guide blocks 8 are fixedly provided at both ends of the connector 1, corresponding to the two sides of the web of the first profile 2 and the second profile 5 respectively. The end of the guide block 8 is provided with a guide slope 81. The guide slope 81 is provided on the side of the guide block 8 facing away from the connector 1 and close to the web of the I-beam. Through the guiding effect of the guide slope 81 on the web, the first profile 2 and the second profile 5 can be guided and positioned between the connector 1, so as to facilitate the insertion of the first profile 2 and the second profile 5 into the slot 11 of the connector 1.
