[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-4As shown, this utility model provides a prefabricated steel structure sloping roof mechanical connection device, including a left connector 1 and a right connector 2, which are symmetrically arranged. A central connecting block 3 is provided in the middle of the left connector 1 and the right connector 2. The top of the central connecting block 3 is provided with a V-shaped guide surface 4 that matches the angle of the sloping roof. One end of the left connector 1 and the right connector 2 near the central connecting block 3 is provided with a chamfered surface 5 that cooperates with the V-shaped guide surface 4. The left connector 1, the right connector 2 and the central connecting block 3 are connected by a locking mechanism 6. By setting the left connector 1, the right connector 2, the central connecting block 3, the V-shaped guide surface 4, the chamfered surface 5 and the locking mechanism 6, the connection device can adapt to sloping roofs of different angles through the cooperation of the V-shaped guide surface 4 and the chamfered surface 5. It has strong applicability. The mechanical locking method makes construction fast and simple, reduces the difficulty of on-site welding and high-altitude operations, and improves work efficiency and construction safety.

[0017] Wear-resistant pads 7 are provided between the chamfered surfaces 5 of the left connector 1 and the right connector 2 and the V-shaped guide surface 4 of the central connector 3. By providing wear-resistant pads 7, the wear resistance of the central connector 3 and the left connector 1 and the right connector 2 can be improved, thereby reducing friction and improving the service life of the central connector 3 and the left connector 1 and the right connector 2.

[0018] The bottom of the central connecting block 3 is provided with a fixed base 8. The fixed base 8 is connected to the eaves of the house through anchor bolts 9. The fixed base 8 and anchor bolts 9 can be initially fixed to the eaves of the house, thereby ensuring the overall stability of the connecting device in subsequent assembly and preventing parts from falling off during the assembly process.

[0019] The left connector 1 and the right connector 2 are made of cast steel or high-strength steel plate, and the central connector 3 is made of forged steel or cast steel.

[0020] The locking mechanism 6 includes a locking bolt 61 that passes horizontally through the central connecting block 3, the left connecting piece 1 and the right connecting piece 2, and a nut 62 that mates with the locking bolt 61. By setting the locking mechanism 6, the left connecting piece 1 and the right connecting piece 2 can be quickly assembled and fixed, which effectively improves the assembly efficiency.

[0021] The ends of the left connector 1 and the right connector 2 are provided with mounting holes 10. The left connector 1 and the right connector 2 are connected to the steel structure 12 through the mounting holes 10 and bolts 11. By setting the mounting holes 10 and bolts 11, the steel structure 12 can be pre-assembled with the left connector 1 and the right connector 2 respectively, without the need for assembly at the top of the eaves, which simplifies the assembly process and improves the efficiency of assembly.

[0022] Working principle: During installation, first fix the central connecting block 3 to the eaves of the house with anchor bolts 9. Then connect the left connecting piece 1 and the right connecting piece 2 to the left and right steel structure components 12 respectively and put them in place. Next, align the beveled surfaces 5 of the left connecting piece 1 and the right connecting piece 2 with the V-shaped guide surface 4 of the central connecting block 3, insert the locking bolt 61 and tighten the nut 62 initially. Finally, use a torque wrench to tighten the nut 62, so that the left connecting piece 1 and the right connecting piece 2 slide and press along the V-shaped guide surface 4, thereby achieving a tight connection of the ridge node. Wear-resistant shims 7 can be added between the beveled surface 5 and the V-shaped guide surface 4 to reduce wear.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
