[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. 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, stadiums, super high-rise buildings and other fields. Steel structure will degenerate at 450-650 degrees Celsius and lose its bearing capacity, resulting in the steel cannot continue to be used.

[0026] Further Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the positioning assembly 6 includes two mounting seats a61, and the two mounting seats a61 are symmetrically distributed and fixed on the top side wall of the horizontal plate 2. A transmission rod 62 slides through the side wall of one side of the mounting seat a61, and a connecting ring 63 is tightly sleeved on the outer surface of the transmission rod 62. A spring 64 is sleeved on the outer surface of the transmission rod 62, one end of the spring 64 is fixed to the side wall of one side of the connecting ring 63, and the other end of the spring 64 is fixed to the side wall of one side of the mounting seat a61; multiple mounting seats b65, multiple mounting seats b65 are symmetrically distributed and fixed to the top side wall of the horizontal plate 2, one side wall of the mounting seat b65 slides through a limiting rod 66, and the side wall of one side of the I-shaped steel 1 A plurality of equally spaced limiting holes 67 are provided, and the limiting rods 66 are matched with the limiting holes 67. A hinge seat a68 is fixed to the side walls adjacent to the two limiting rods 66. A hinge seat b69 is fixed to one end of the transmission rod 62. A connecting rod 610 is hinged between the hinge seat b69 and the hinge seat a68. Through the setting of the positioning component 6, the cross plate 2 can be effectively positioned and installed, so that the positioning of the cross plate 2 can be completed quickly and smoothly, and the situation that the cross plate 2 needs auxiliary support due to lack of support points when being fixed is effectively solved, and the installation efficiency of the cross plate 2 is greatly improved, so that it is suitable for fire-fighting work needs under different application requirements.

One end of the limiting rod 66 is set with a chamfered slope. Through the setting of the pull ring 8, it is convenient for the staff to pull the pull ring 8 for operation. The chamfered slope at one end of the limiting rod 66 makes it more stable when it is engaged with the limiting hole 67.

[0028] This solution has the following working process: when the spliced ​​cross plate 2 needs to be installed for use, first connect the cross plate 2 between the two I-shaped steels 1, and pull the pull ring 8 to ensure that the position of the limiting rod 66 coincides with the position of the limiting hole 67. Through the elastic action of the spring 64, the transmission rod 62 rebounds and resets after being stressed. The transmission action of the connecting rod 610 is used to drive the limiting rod 66 to move synchronously until the limiting rod 66 is engaged with the limiting hole 67, thereby completing the preliminary positioning of the cross plate 2.

[0029] According to the above working process, it can be known that: through the setting of the positioning component 6, the cross plate 2 can be effectively positioned and installed, so that the positioning of the cross plate 2 can be completed quickly and smoothly, and the situation that the cross plate 2 needs auxiliary support due to the lack of support points when it is fixed can be effectively solved, and the installation efficiency of the cross plate 2 can be greatly improved, so that it is suitable for fire extinguishing work needs under different application requirements, and through the setting of the fire retardant coating 7, the fire retardant coating 7 can effectively provide a fireproof effect for the I-shaped steel 1 and the cross plate 2, and can improve the fire resistance of the I-shaped steel 1 and the cross plate 2, so as to slow down the speed of flame spread or prevent the burning of the flame within a certain period of time, and cooperate with the I-shaped steel 1 to connect through the cross plate 2, so as to further improve the overall structural strength and reliability.

[0030] Further as Figure 3 and Figure 5 As shown, it is worth explaining in detail that the number of the limit holes 67 is consistent with the number of the hole slots 4, and the angle between the cross plate 2 and the I-shaped steel 1 is set at a right angle. The number of the limit holes 67 and the hole slots 4 is consistent, which makes it convenient for the staff to adjust the position of the cross plate 2.

[0031] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that a plurality of symmetrically distributed positioning plates 9 are fixed to the side wall of one side of the I-shaped steel 1, and a plurality of symmetrically distributed positioning grooves 10 are opened on the side wall of one side of the cross plate 2. The positioning plates 9 are slidably connected to the inside of the positioning grooves 10. By setting the positioning plates 9 and the positioning grooves 10, the stable and smooth sliding between the cross plate 2 and the I-shaped steel 1 is ensured, thereby avoiding the situation where the cross plate 2 moves and causes jamming.

[0032] Further as Figure 2 and Figure 4As shown, it is worth explaining in detail that two symmetrically distributed mounting plates 11 are fixed to the top side wall of the transverse plate 2, and a connecting pipe 12 is commonly fixed to the side wall adjacent to the two mounting plates 11, and a connected water pipe 13 is fixed to the outer surface of the connecting pipe 12, and a plurality of equidistantly distributed water pipes 14 are fixed to the outer surface of the connecting pipe 12. Through the coordinated arrangement of the water pipe 14, the connecting pipe 12 and the water pipe 13, it can be suitable for waterproofing work around the building, thereby improving the fire resistance of the building, effectively reducing the temperature around the I-shaped steel 1 and the transverse plate 2, thereby further increasing the fire resistance time of the I-shaped steel 1 and the transverse plate 2.

[0033] In summary: through the setting of the pull ring 8, it is convenient for the staff to pull the pull ring 8 for operation, and the chamfered inclined surface of one end of the limiting rod 66 makes it more stable when it is engaged with the limiting hole 67, and the number of limiting holes 67 and the hole grooves 4 are consistent, so that it is convenient for the staff to adjust the position of the cross plate 2, and through the setting of the positioning plate 9 and the positioning groove 10, the stable and smooth sliding between the cross plate 2 and the I-shaped steel 1 is ensured, and the situation where the cross plate 2 moves and causes jamming is avoided. Through the coordinated setting of the water spray pipe 14, the connecting pipe 12 and the water supply pipe 13, it can be suitable for waterproofing work around the building, thereby improving the fire resistance of the building, effectively reducing the temperature around the I-shaped steel 1 and the cross plate 2, thereby further increasing the fire resistance time of the I-shaped steel 1 and the cross plate 2.
