[0030] Before using this equipment, the staff will make the cushion block bases 2 of different shapes according to the needs. When the steel column 1 is cylindrical, the staff can adhere the multiple fireproof bases 2 of curved surface structure to the outer surface of the cylindrical steel column 1 by strong glue according to the needs. When the steel column 1 is a rectangular structure, the staff will adhere the multiple cushion block bases 2 of ordinary rectangular structure to the middle of the steel column 1 by strong glue, and at the same time adhere the multiple cushion block bases 2 with right-angled structures to the corners of the steel column 1 by strong glue.

At this time, due to the action of the locking spring 601, the locking plate 6 rotates, so that the locking plate 6 presses the outer side of the wire mesh 3 tightly, thereby ensuring the stability of the wire mesh 3. Further, the staff pushes the wire mesh 3 into the interior of multiple pad bases 2 at one time, thereby completing the fixing of the wire mesh 3.

[0031] The working process of the utility model is as follows: before using the device, the staff makes the cushion block bases 2 of different shapes according to the needs. When the steel column 1 is cylindrical, the staff can adhere the cushion block bases 2 of multiple curved surface structures to the outer surface of the cylindrical steel column 1 by strong glue according to the needs. When the steel column 1 is a rectangular structure, the staff adheres the cushion block bases 2 of multiple ordinary rectangular structures to the middle of the steel column 1 by strong glue, and at the same time adheres the cushion block bases 2 of multiple right-angled structures to the steel column 1 by strong glue. The staff further pushes the wire mesh 3 into the inner side of the wire positioning rod 4 on one of the cushion block bases 2. When the wire mesh 3 is close to the wire positioning rod 4, the wire mesh 3 applies pressure to a group of the positioning blocks 5, so that the positioning blocks 5 move outward due to the structure of the positioning blocks 5, thereby pushing the positioning block moving rod 501 to move outward. When the wire mesh 3 enters the inner side of the positioning block 5, the positioning block 5 returns to the inner side due to the action of the positioning block moving spring 502. The wire mesh 3 is positioned to prevent the wire mesh 3 from falling. The staff further pushes the wire mesh 3 toward the inside of the wire positioning rod 4, so that the wire mesh 3 is pushed into the inside of the locking plate 6, so that the wire mesh 3 provides a force for the clamping main plate 7 and the clamping sub-plate 8, so that the clamping main plate 7 rotates following the clamping main plate rotation axis 701, and the clamping sub-plate 8 rotates following the locking sub-plate rotation axis 801, so that the clamping main plate 7 and the clamping sub-plate 8 clamp the wire mesh 3. Thereby ensuring the stability of the wire mesh 3, when the diameter of the wire mesh 3 is larger than the diameter of the clamping main plate 7 and the clamping sub-plate 8, the clamping main plate 7 and the clamping sub-plate 8 clamp the wire mesh 3. At this time, due to the action of the locking spring 601, the locking plate 6 is rotated, so that the locking plate 6 presses the outer side of the wire mesh 3 tightly, thereby ensuring the stability of the wire mesh 3. Further, the staff pushes the wire mesh 3 into the interior of multiple pad bases 2 at one time, thereby completing the fixing of the wire mesh 3.
