[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure includes steel beams, steel columns, steel trusses, etc., and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, bridges and other fields.

[0011] The beneficial effect of the utility model is that the steel structure building connector for building realizes the positioning of the second steel beam through the cooperation between the plate body, the straight rod and the spring, avoiding the deviation of the second steel beam to produce gaps or misalignment of the bolt holes during welding or connecting bolts, and solves the problem that the existing connectors are prone to deviations during the connection process relying only on the lifting machine, thereby affecting the subsequent welding or connection work of bolts and rivets.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Existing connectors that rely solely on a lifting machine are prone to deviation during the connection process, which in turn affects subsequent welding or connection work with bolts and rivets.

[0020] In view of this, a steel structure building connector for construction is provided, which realizes the positioning of the second steel beam through the cooperation between the plate body, the straight rod and the spring, thereby avoiding the deviation of the second steel beam to produce gaps or misalignment of the bolt holes during welding or connecting bolts, and solves the problem that the existing connectors are prone to deviations when relying only on the lifting machine during the connection process, thereby affecting the subsequent welding or connection work of bolts and rivets.

[0021] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0022] Depend on Figure 1 and 4 It can be seen that a steel structure building connector for construction includes a first steel beam 1 and a second steel beam 2, one side of the first steel beam 1 and the end face of the second steel beam 2 are fitted together, one side of the first steel beam 1 is fixedly connected to two back plates 3 fitted to the left and right sides of the second steel beam 2, and the upper and lower sides of the second steel beam 2 are respectively fitted with two plate bodies 5 fixed to the back plates 3, and the upper end of the plate body 5 is provided with a positioning mechanism; the positioning mechanism includes a limit plate 17, a block 13, a straight rod 14 and an arc plate 16; the bottom of the limit plate 17 is fixedly connected to the upper end of the second steel beam 2, the side of the limit plate 17 is abutted against the side of the plate body 5, the top of the plate body 5 is fixedly connected to the block 13, the top of the block 13 is rotatably connected to the straight rod 14 through a pin shaft, and one end of the straight rod 14 is fixedly connected to the arc plate 16 movably connected to the top of the limit plate 17.

[0023] In the specific implementation process, it is worth pointing out that the arc plate 16 can be inserted into the top arc groove 171 of the limit plate 17 for positioning. Through the cooperation between the block 13, the straight rod 14 and the arc plate 16, the positioning of the second steel beam 2 is achieved, avoiding the deviation of the second steel beam 2 to produce gaps or bolt hole misalignment during welding or bolt connection, and solving the problem that the existing connecting parts are prone to deviation during the connection process by relying only on the lifting machine, thereby affecting the subsequent welding or bolt and rivet connection work;

[0024] Furthermore, a spring 15 is provided at the pin end of the straight rod 14, and both ends of the spring 15 are fixedly connected to the straight rod 14 and the block 13 respectively;

[0025] In the specific implementation process, it is worth pointing out that the device can drive the arc plate 16 to be inserted into the arc groove of the limit plate 17 for positioning by relying on the elastic deformation of the spring 15;

[0026] Furthermore, the back plate 3 is fixedly connected to the second steel beam 2 by a plurality of bolts 4;

[0027] In the specific implementation process, it is worth pointing out that the device can connect the back plate 3 with the second steel beam 2 through the bolts 4;

[0028] Specifically, when using the building steel structure connecting piece, the user lifts the second steel beam 2 and then aligns the second steel beam 2 with the plate body 5 and the back plate 3, so that the limiting plate 17 on the second steel beam is aligned with the plate body 5 and inserted, and the straight rod 14 is rotated to disengage the curved plate 16 before being fully inserted. After being fully inserted, the straight rod 14 is released. At this time, the elastic deformation of the spring 15 can drive the curved plate 16 to be inserted into the curved groove 171 of the limiting plate 17 for fixation, thereby preventing the second steel beam 2 from moving at will.

[0032] In the specific implementation process, it is worth pointing out that the support block 9 has the same “I” shape as the second steel beam 2, and can be snapped onto the second steel beam 2 to support the second steel beam 2, thereby improving the longitudinal compressive strength of the second steel beam 2;

[0033] Specifically, on the basis of the above embodiment, through the cooperation between the first steel beam 1, the second steel beam 2 and the reinforcing rib 10, the strength of the connection position between the first steel beam 1 and the second steel beam 2 is increased, and the stability of the steel structure is further improved.
