[0002] In modern buildings, in order to prevent the indoor temperature of the top floor from rising due to sun exposure, overhead insulation boards are usually laid on the roof to prevent damage to the roof due to sun exposure. In order to prevent water leakage from the roof, a waterproof layer is laid under the insulation layer. After years of wind and rain erosion, these protective layers will crack, sand and peel off, and even seepage will occur. The waterproof layer needs to be repaired (generally, the waterproof layer will be re-laid). The usual waterproof repair design is to remove the insulation layer and the protective layer, and then carry out waterproof construction. After the waterproof construction is completed, the protective layer and the insulation layer are restored.

The top of the rotating shaft 11 is in the shape of a rocker, which is convenient for operation. The first frame 1 and the second frame 2 are both slidably connected with a driving plate 5. The end of each driving plate 5 close to the rotating shaft 11 is fixedly connected to the corresponding steel wire rope 12. When in use, the rotating shaft 11 is rotated to make the steel wire rope 12 wrap around the middle of the rotating shaft 11. At this time, the steel wire rope 12 makes each driving plate 5 slide toward the end close to the rotating shaft 11, and the pulling frame 3 slides upward in the vertical direction. At least two guide grooves 21 are opened on the inside of the first frame 1 and the second frame 2, and the guide grooves 21 are arranged in the vertical direction. The first frame 1 and the second frame 2 are slidably connected with a pulling frame 3, and a plurality of positioning protrusions 22 are fixedly connected to one side of the pulling frame 3. Each positioning protrusion 22 is placed in a corresponding guide groove 21. The positioning protrusion 22 is limited by the guide groove 21, so that the pulling frame 3 can only slide in the vertical direction relative to the first frame 1 and the second frame 2. An inclined groove 4 is opened in the middle of each pulling frame 3, and one side of each driving plate 5 is placed in the inclined groove 4. The position of the driving plate 5 corresponding to the inclined groove 4 is a circular protrusion.

Filling tube 7, the top of the filling tube 7 is in a trumpet shape, which is convenient for pouring cement mortar. Among them, the height of the filling tube 7 is higher than the height of the first frame 1 and the second frame 2. When in use, a hole is opened at the top of the broken brick and the filling tube 7 is inserted into the hole.The expansion sleeve 8 is slidably sleeved on the outside of the filling tube 7. The expansion sleeve 8 has a wavy curved ring structure. The expansion sleeve 8 is made of folded paper material with toughness. When in use, the expansion sleeve 8 is folded and sleeved on the outside of the filling tube 7, and then the expansion sleeve 8 is pushed along the filling tube 7 into the lower side of the broken brick, and then cement mortar is introduced into the filling tube 7. Then the cement mortar enters the expansion sleeve 8, and the expansion sleeve 8 opens to increase its diameter. After the cement mortar in the expansion sleeve 8 is fully filled, the filling tube 7 is pulled out, and after waiting for the cement mortar to solidify, the cement mortar supports the broken brick, and Use cement mortar to fill the holes on the top of the bricks. After the insulation board is repaired, only the damaged surface of the insulation board needs to be repaired with anti-cracking mortar. In areas with severe sanding, use a sand fixer or base hardener for sand fixation. Then use road pavement repair material, add polymer waterproof coating and stir evenly, then use a scraper to scrape and spread it on the base surface, and maintain an appropriate thickness. On the roof, lay the waterproof material while brushing it, and then spray a rigid coating of appropriate thickness on the surface of the waterproof layer to keep the insulation layer in good hardness, wear resistance and anti-aging properties. It can directly replace the protective layer and meet the requirements of rooftops. At least one L-shaped hook plate 6 is provided in the first frame 1 and the second frame 2.
