DETAILED DESCRIPTION
[0020] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.
[0021] The design of the utility model mainly consists of an erection system and a lower fastening system, and has two specific implementation methods of fixing I-beams 1-8 and fixing box steel beams 2-10.
[0022] <Example 1>:
[0023] See also Figure 1 、 2 The fixed erection system is fixed by welding the vertical steel pipe 1-1 to the fixed end square steel 1-2, and then slidingly connected with the horizontal movable square steel 1-3 on both sides.
[0024] The bottom of the lower fastening system is the I-beam 1-8 beam. By sliding in the fixed end square steel 1-2, the L-shaped inner groove of the movable square steel 1-3 is close to the top flange plate of the I-beam 1-8. The high-strength bolts 1-5 pass through the two sides of the transverse movable square steel 1-3, and the top of the bolts is pressed against the flange plate of the I-beam 1-8. By tightening the nuts, the movable square steel 1-3 and the flange plate of the I-beam 1-8 are fixedly connected under the pressure formed by the bolts and nuts.
[0025] The through hole 1-6 on the top of the vertical steel pipe 1-1 of the fixed frame system is crossed by the safety rope 1-7, forming a network lifeline system as a safety protection device. Workers can hang the safety rope hook on the safety rope 1-7 to prevent accidental falls during high-altitude operations.
[0026] <Example 2>:
[0027] See also Figure 3-5 .
[0028] The fixed erection system is fixed by welding the vertical steel pipe 2-1 to the fixed end square steel 2-2, and then slidingly connected with the horizontal movable square steel 2-3 on both sides.
[0029] The fixed erection system has a box steel beam 2-10 at its bottom. The transverse movable square steel 2-3 slides with the fixed end square steel 2-2, allowing the groove on the inner side of the transverse movable square steel 2-3 to abut against the side of the box steel beam 2-10. The lower end of the transverse movable square steel 2-3 is sleeved with a vertical movable square steel 2-4. The vertical movable square steel 2-4 slides with the transverse movable square steel 2-3 to abut against the lower end of the box steel beam 2-10.
[0030] The transverse movable square steel 2-3 is provided with a second bolt 2-9 and a first bolt 2-5. The second bolt 2-9 passes through the transverse movable square steel 2-3, and the top of the second bolt 2-9 abuts against the box steel beam 2-10. By tightening the second nut 2-8, the transverse movable square steel 2-3 and the box steel beam 2-10 are fixedly connected under the pressure of the bolt and nut.
[0031] The first bolt 2-5 passes through the transverse movable square steel 2-3. The top of the first bolt 2-5 presses against the vertical movable square steel 2-4 sleeved inside the transverse movable square steel 2-3. When the first nut 2-6 is tightened, the transverse movable square steel 2-3 and the vertical movable square steel 2-4 are fixed in a relatively static position under the pressure of the bolt and nut. A lower gasket 2-7 is also provided on the inner side of the bottom groove of the vertical movable square steel 2-4 to increase the friction between it and the box steel beam 2-10. The through hole 1-6 at the top of the vertical steel pipe 2-1 passes through the safety rope 1-7, forming a mesh lifeline system as a safety protection device. Workers can hang the safety rope hook on the safety rope 1-7 to prevent accidental falls during high-altitude operations.
[0032] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
