[0002] Steel structure buildings use steel as the main structural material, showing strength and stability. They are light and strong, can support weight and span, provide flexibility and diversity for design, have a simple appearance and smooth lines. The construction is efficient and fast, which can shorten the construction period.

[0003] In the installation of steel structure buildings, bolts are usually used to fix the steel structure joints. For example, a steel structure connection node disclosed in the utility model patent with the authorized patent announcement number CN216810310U includes a structural beam, a corbel, an upturned beam and a drop-plate cantilever beam; wherein the structural beam is an I-beam structure; the corbel is fixed to a web on one side of the structural beam, and the upturned beam is fixed to the side of the corbel away from the structural beam; a connecting plate is fixed on the side of the structural beam away from the corbel, and the drop-plate cantilever beam is fixed to the side of the connecting plate away from the structural beam. However, during the installation of the steel structure beam, a crane is required to hoist the crossbeam. During the construction process, the crossbeam and the longitudinal I-beam column need to maintain a high stability for docking and installation. The alignment of the bolt installation holes of the crossbeam and the longitudinal column affects the construction speed. Therefore, a high-strength steel structure connecting fastener that can facilitate the installation of the steel structure connection node is required. Summary of the invention

[0004] In view of the above problems, the utility model proposes a high-strength steel structure connecting fastener, which effectively solves the problem in the prior art that the bolt holes of the beam connection nodes in the steel structure construction are inconvenient for docking and installation, thereby affecting the construction progress.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a high-strength steel structure connecting fastener, including a positioning plate and two clamping plates, a longitudinal slot is opened in the middle of the positioning plate, a sliding slot is opened longitudinally on the rear side of the positioning plate, a connecting plate slot is opened longitudinally at the bottom of the sliding slot, the longitudinal slot is connected to the connecting plate slot, the two clamping plates are respectively located at the left and right ends of the rear side of the positioning plate, the two clamping plates are both slidably connected to the positioning plate, the positioning plate is symmetrically provided with positioning mounting holes on the left and right, the two clamping plates are provided with positioning screw holes corresponding to the positioning mounting holes, the inner side of the positioning mounting hole is also provided with a fastening bolt through hole, and the two clamping plates are provided with fastening screw holes corresponding to the fastening bolt through holes.

[0006] Furthermore, the positioning and mounting holes are located on both sides of the connecting plate groove.

[0007] Further, sliding shaft holes are formed on both sides of the positioning plate, and sliding shafts are arranged on the front sides of the two clamping plates. The sliding shafts are respectively inserted into the sliding shaft holes to form a sliding connection.

[0008] Further, a spring hole is formed on the front side of the positioning plate, and springs sleeved on the sliding shafts are arranged in the spring holes. An annular boss that is slidably matched with the inner wall of the spring hole is arranged on the sliding shaft. The two ends of the spring respectively abut against the bottom of the spring hole and the annular boss.

[0009] Further, two sliding shafts are connected to each of the two clamping plates. The number of the sliding shaft holes corresponds to the number of the sliding shafts. A push handle for connecting the two sliding shafts is arranged at the front end of the sliding shaft.

[0010] Further, handles are arranged on both sides of the positioning plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model pre-installs the installation node part through the arranged positioning plate and the two clamping plates, so that the clamping plates cooperate with the positioning plate to clamp on the I-shaped steel column. At this time, after the I-shaped steel column is installed in place, the cross beam is hoisted. At this time, only the two ends of the cross beam need to be clamped in the connecting plate groove, and then the screw holes formed in the connecting plates at the two ends of the cross beam can be aligned with the hole positions on the I-shaped steel column, which is convenient for bolt installation.

[0013] Meanwhile, after the connecting plates at the two ends of the cross beam are clamped in the connecting plate groove, the hoisting of the cross beam can be cancelled and bolts can be installed. At this time, the fixedly installed positioning plate supports the two ends of the cross beam, greatly improving the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A sliding slot 4 is longitudinally opened on the rear side surface of the positioning plate 1, and a connecting plate slot 5 is longitudinally opened at the bottom of the sliding slot 4. The longitudinal card slot 3 is communicated with the connecting plate slot 5. The two clamping plates 2 are respectively located at the left and right ends of the rear side surface of the positioning plate 1, and the two clamping plates 2 are both slidably connected to the positioning plate 1. Positioning installation holes 6 are symmetrically opened on the left and right of the positioning plate 1, with three positioning installation holes 6 longitudinally arranged on each side of the longitudinal card slot 3. Positioning screw holes 7 corresponding to the positioning installation holes 6 are opened on the two clamping plates 2. A fastening bolt passing hole 8 is further provided inside the positioning installation hole 6. The fastening bolt passing hole 8 is a plurality of circular holes arranged longitudinally. Fastening screw holes 9 corresponding to the fastening bolt passing holes 8 are opened on the two clamping plates 2.

[0020] In this embodiment, the positioning installation holes 6 are located on both sides of the connecting plate slot 5.

[0021] In this embodiment, sliding shaft holes are opened on both sides of the positioning plate 1, and threaded holes are opened on the front side surfaces of the two clamping plates 2. Sliding shafts 10 are respectively threadedly connected in the threaded holes, and the front ends of the sliding shafts 10 are respectively inserted into the sliding shaft holes to form a sliding connection.

[0022] In this embodiment, spring holes are opened on the front side surface of the positioning plate 1. The spring holes are coaxially opened with the sliding shaft holes. Springs 11 sleeved on the sliding shafts 10 are respectively arranged in the spring holes. An annular boss 12 that is slidably matched with the inner wall of the spring hole is integrally connected to the sliding shaft 10. The two ends of the spring 11 respectively abut against the bottom of the spring hole and the annular boss 12. The clamping plates 2 are attached to the positioning plate 1 by the elastic potential energy of the spring 11, so that the positioning plate 1 and the clamping plates 2 can clamp on the I-beam, facilitating the installation of positioning screws.

[0023] In this embodiment, two of the clamping plates 2 are each connected to two sliding shafts 10. The two sliding shafts 10 are arranged longitudinally. The number of the sliding shaft holes corresponds to the number of the sliding shafts 10. By providing the two sliding shafts 10, the deflection of the clamping plate 2 is prevented, improving stability.
