Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, in particular to a building steel structure connection structure. Background Art

[0002] Steel structure connection refers to the mutual connection between steel structure members or components. Steel structure connection is usually connected by weld connection, bolt connection or rivet connection. Weld connection and rivet connection are more suitable for some steel structure connections that do not require subsequent disassembly and assembly. For some temporary steel structure connections, bolt connection is generally used. However, in the process of using bolts to connect steel structures, one connection position often requires the operation of multiple bolts, which wastes a long time in the installation and disassembly process. Moreover, the bolts are scattered before installation and are easy to fall during high-altitude installation, which is very dangerous. Therefore, it is of great significance to study a new building steel structure connection structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0024] like Figure 1-6As shown, the utility model provides a technical solution: a building steel structure connection structure, including a connection seat 1, two I-shaped steels 2 are arranged in the connection seat 1, the two I-shaped steels 2 are butt-jointed, the shape of the connection seat 1 is adapted to the shape of the I-shaped steel 2, so that the I-shaped steel 2 can be smoothly butt-jointed in the connection seat 1, four transverse holes 4 and four longitudinal holes 3 are opened on the I-shaped steel 2, both sides of the connection seat 1 are fixedly connected with a threaded fixing structure 5, the threaded fixing structure 5 includes a screw 51, both ends of the screw 51 are rotatably connected to the connection seat 1 through bearings 54, the bearings 54 can support the screw 51, and the bearings 54 can reduce the rotation resistance of the screw 51, thereby maintaining the smooth rotation of the screw 51, the middle part of the screw 51 is fixedly connected with an operating block 53, and the operating block 53 can be used to The screw rod 51 is used as a force application point to facilitate the staff to rotate the screw rod 51. Two nuts 52 are threadedly connected to the screw rod 51. The threads on both sides of the screw rod 51 are arranged oppositely. The threads of the screw rod 51 are arranged oppositely from the middle to the two sides. The rotation of the screw rod 51 can drive the two nuts 52 to move away from or close to each other, thereby controlling the movement of the connecting plate 61, so that the connecting plate 61 drives the locking rod 62 to move, so that the locking rod 62 can be smoothly inserted into the longitudinal hole 3, thereby connecting the two I-shaped steels 2. Two clamping structures 6 are fixedly connected to the threaded fixing structure 5. The clamping structure 6 includes a connecting plate 61, which is fixedly connected to the nut 52. Four locking rods 62 are fixedly connected to the connecting plate 61. The locking rod 62 can slide in the connecting seat 1 to avoid locking. The rod 62 turns to make the connecting plate 61 and the nut 52 move smoothly, and can ensure that the locking rod 62 is smoothly inserted into the longitudinal hole 3. The locking rod 62 is inserted into the corresponding longitudinal hole 3, and the longitudinal hole 3 can provide a fixing point for the locking rod 62. The four ends of the positioning structure 6 pass through the connecting seat 1 and are inserted into the four longitudinal holes 3, and two hinge structures 8 are fixedly connected between the two positioning structures 6. The hinge structure 8 includes a connecting block 81, and the connecting block 81 is fixedly connected to the connecting strip 10.

The hinge structure 8 is fixedly connected with a connecting strip 10, one end of the connecting strip 10 is fixedly connected with the movable plate 9, and one side of the movable plate 9 is fixedly connected with four fixed rods 7. The fixed rod 7 can slide in the connecting seat 1 to keep the fixed rod 7 moving smoothly, so that the fixed rod 7 can smoothly enter the transverse hole 4, and the four fixed rods 7 pass through the connecting seat 1 and are inserted into the corresponding transverse holes 4.The transverse hole 4 can provide a fixing point for the fixing rod 7.

[0025] The working principle of the utility model is as follows: by docking two I-shaped steels 2 on the connecting seat 1, and then rotating the operating block 53, the operating block 53 drives the screw 51 to rotate, and the screw 51 drives the two nuts 52 to move away from each other, so that the two nuts 52 drive the two connecting plates 61 to move away from each other, and the connecting plate 61 drives the locking rod 62 to move, so that the locking rod 62 is inserted into the longitudinal hole 3, and when the two connecting plates 61 move away from each other, the connecting plate 61 drives the connecting rod 82 to make an angular turn through the supporting block 83, so that the connecting rod 82 drives the connecting bar 10 to move through the connecting block 81, the connecting bar 10 drives the movable plate 9 to move, and the movable plate 9 drives the fixing rod 7 to move, so that the fixing rod 7 is inserted into the transverse hole 4, thereby completing the connection of the two I-shaped steels 2.
