Specifically, after the side edge of the screening plate 123 slides into the inner chute 124, the poke rod 304 rotates around one end of the cylinder 307 toward a direction close to the screening plate 123, the poke rod 304 moves in the notch 309 and abuts against the side wall of the notch 309, the inclined rod 311 rotates around the positioning shaft 302 and abuts against the matching rod 312, the pressure head 313 presses the screening plate 123, in addition, the cross rod 314 is pulled while the poke rod 304 rotates around one end of the cylinder 307 toward a direction close to the screening plate 123, the cross rod 314 rotates around the rotating shaft 305, the raised head 316 abuts against the side wall of the screening plate 123, and then the nut 308 is screwed until the nut 308 presses the matching rod 312, so that the position locking of the screening plate 123 is completed; conversely, if the screening plate 123 is to be removed, the nut 308 can be turned reversely until the nut 308 no longer presses the matching rod 312, then the poke rod 304 is turned reversely to reset, and then the pressure head 313 and the raised head 316 are not in contact with the screening plate 123, and then the side block 301 is rotated 180 ° around the movable shaft 317, at this time, the locking unit no longer blocks the removal path of the screening plate 123, so that the screening plate 123 can be replaced.
The invention also provides a production formula of the moisture-proof high-strength self-leveling mortar, which is prepared by adopting a moisture-proof high-strength self-leveling mortar production device and specifically comprises the following raw materials:
100-120 parts of gypsum powder, 600-650 parts of silica sand, 40-60 parts of high-alumina cement, 20-40 parts of silica fume, 1-3 parts of water reducing agent, 4-6 parts of water repellent, 2-4 parts of cellulose, 0.5-1.5 parts of porous modified polyester fiber, 20-40 parts of latex powder and 200-300 parts of portland cement.
The porous modified polyester fiber is added into the mortar, so that the mortar can permeate into holes when the mortar is used, the binding force between the mortar and the fiber is increased, the anti-cracking effect of the mortar is increased, the use of a water repellent is increased, the product structure is improved, and the compactness is improved, so that the moisture-proof effect is achieved. The mortar has low density, is beneficial to reducing building load of floors, has excellent compression resistance and bending resistance, low shrinkage, difficult cracking and good fluidity, is widely applied to the foundation of filling and leveling floors, develops high-strength self-leveling mortar which can resist water soaking for more than 180 days by adding waterproof media, improving system structures and other methods, can be applied to backfill leveling of underground engineering and humid places, and can also develop and adapt to various color systems by considering the surface layer decoration effect of materials.
The invention also provides a construction method of the moisture-proof high-strength self-leveling mortar, which comprises the following steps: adding water into the raw materials, and uniformly stirring to ensure that the initial fluidity of the mortar is 130mm; uniformly pouring the stirred mortar on the ground coated with the interface agent, spreading the mortar with the aid of a tooth rake, and then rolling and defoaming the mortar for a plurality of times to and fro by using a defoaming roller; covering the surface of the mortar with a plastic preservative film within 80-100min after the mortar is finally set, and sealing and maintaining for 35-45h; and after the maintenance is finished, taking down the preservative film, uniformly coating a hardening agent on the surface of the mortar, and naturally drying and forming. By the method, the mortar is applied to the ground, and the ground has the advantages of flat and smooth surface, good wear resistance, strong impact resistance and excellent waterproof performance.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
