[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] According to Figure 1 —4 shows: The present utility model provides an installation structure of a PCF board for an assembled steel structure residence: including a PCF board body 1; on both sides of the rear of the PCF board body 1, there are symmetrically arranged connecting platforms 2 with a guiding function. The PCF board body 1 is positioned by a telescopic rod 3 whose end extends into the lower part of the connecting platform 2. On the connecting platform 2, there is an adjusting bolt 4 that can adjust the gap between the connecting platform 2 and the end of the telescopic rod 3. The telescopic rods 3 on the same side are arranged on a steel column 5 of the steel structure residence. The PCF board body 1 and the telescopic rod 3 are fixed by angle steels 7 inserted into connecting plates 6 arranged on both sides of the lower part of the two sides of the connecting platform 2 and on both sides of the telescopic rod 3; by arranging the connecting platform 2 with a guiding function and cooperating with the telescopic rod 3 whose end extends into the lower part of the connecting platform 2 to position the PCF board body 1, the PCF board body 1 can be quickly positioned during hoisting, and after positioning, the crane can hoist the next PCF board body 1. The design of the telescopic rod 3 and the adjusting bolt 4 makes it convenient to adjust the PCF board body 1;

[0021] According to Figure 1 , 4 As shown: Above and on one side of the PCF board body 1, there are bosses 101, and below and on the other side, there are grooves 102. On both sides of the bosses 101 above the PCF board body 1, there are symmetrically arranged lifting holes 103 convenient for the crane to hoist. There is no groove 102 below the PCF board body 1 installed at the bottom; the bosses 101 and grooves 102 enable any two PCF board bodies 1 to be connected together, so the integrity is better;

[0022] According to Figure 1 , 2As shown in the figure: The lower part of the connecting platform 2 is provided with a guiding groove 201 that gradually narrows upward. From the guiding groove 201 to the upper end face of the connecting platform 2, there are threaded holes 202 that cooperate with the adjusting bolts 4; the telescopic rod 3 includes an outer rod 301 fixedly arranged at one end on the steel column 5, and an inner rod 302 slidably arranged inside the outer rod 301. At one end of the outer rod 301 close to the inner rod 302, there is a second threaded hole 303, and a fastening bolt 304 is threadedly connected inside the second threaded hole 303. One end of the inner rod 302 protrudes, and above the protruding end, there is a guiding block 305 corresponding to the guiding groove 201; the length of the threaded part of the adjusting bolt 4 is greater than the depth of the threaded hole 202; in this way, by changing the length of the inner rod 302 extending out of the outer rod 301 and then fixing it with the fastening bolt 303, the distance between the PCF board body 1 and the steel column 5 of the steel structure residence can be determined. Then, by screwing the adjusting bolt 4 into the first threaded hole 202, the lower end of the adjusting bolt 4 is made to abut against the lower end of the guiding block 305, and then by continuing to rotate, the connecting platform 2 can be lifted, thereby lifting the height of the PCF board body 1;

[0023] According to Figure 1 、 3 、As shown in Figure 4: The connecting plate 6 is provided with fixing grooves 601.

The angle steel 7 is inserted and connected with two adjacent fixing grooves 601. In this way, under the action of its own gravity, the guiding groove 201 will be stuck outside the guiding block 305, and then the PCF board body 1 and the telescopic rod 3 can be fixed through the angle steel 7, thereby preventing the PCF board body 1 from tipping over.

[0024] The principle of the present utility model: When in use, first weld one end of the outer rod 301 of the telescopic rod 3 to the same steel column 5 of the steel structure residence according to the installation height of the PCF board body 1 and the distance between two connecting platforms 2 on the same side. Then, adjust the length of the inner rod 302 extending out of the outer rod 301 according to the distance between the PCF board body 1 and the steel column 5. Then, after fixing it with the fastening bolt 303, hook the hook of the crane to the lifting hole 103 and connect the guy ropes. During the lifting operation, when it is necessary to lower the PCF board body 1, use the guy ropes to determine the angle of the PCF board body 1, so that the guiding block 305 is inserted into the guiding groove 201. The guiding groove 201 that gradually narrows upward cooperates with the guiding block 305 that gradually narrows upward, so that the guiding block 305 can be quickly inserted into the guiding groove 201. Then, insert the angle steel 7 into any two adjacent fixing grooves 601, and in this way, the position of the PCF board body 1 is fixed. If there is a deviation in the height during the welding of the telescopic rod 3, the PCF board body 1 can be slightly lifted by screwing the adjusting bolt 4 into the first threaded hole 202.
