The invention discloses an escalator floor board supporting structure which comprises a supporting frame, a locking support, supporting bolts and displacement bolts. The supporting frame comprises a vertical face and a transverse face. The transverse face comprises a supporting face and a water collecting groove. A water drainage hole is formed in the bottom of the water collecting groove. A T-shaped groove is formed in the back of the supporting face. The locking support is provided with a supporting hole and a displacement hole. Heads of the displacement bolts are arranged in the transverseportion of the T-shaped groove, and screws of the displacement bolts penetrate through the T-shaped groove and the displacement hole to fix the locking support and the supporting frame to the displacement bolts. Heads of the supporting bolts are used for being supported on the bottom face of the T-shaped groove, and screws of the supporting bolts are used for penetrating through the supporting hole of the locking support to fix the locking support into a bolt hole of an escalator truss in a bolt manner. The invention further discloses a supporting frame. The structure can have functions of supporting a floor board and collecting and draining water, the structure is concise and high in waterproof function, adjustment of the supporting frame in the height direction and rotation in the planeof the floor board are facilitated, the error can be made up, the assembling clearance is ensured, the assembling efficiency is high, and the error-tolerant rate is high.

The invention provides ceramic tile glue and a preparation method and application thereof. The ceramic tile glue is prepared from the following raw materials in parts by weight: 500 to 700 parts of cement, 25 to 50 parts of re-dispersible latex powder, 5.5 to 6.5 parts of water-retaining agent, 250 to 300 parts of quartz sand and 150 to 200 parts of gypsum powder. The ceramic tile glue has super strong bonding force and wide applicability, and can be used directly on smooth base planes such as old ceramic tiles and glass; by adopting the tile glue, the old ceramic tiles do not need to be shoveled, the ceramic tiles do not need to be wetted with water, operation is simplified, construction cost is lowered, the working efficiency is increased, and pollution and damage to the environment are avoided.

The invention relates to a high-polymer modified asphalt waterproof roll for roads and bridges. The high-polymer modified asphalt waterproof roll is manufactured in the way that a bank base layer (1) is used; modified asphalt coating and covering layers (2) and (3) are respectively bonded on the upper and lower surfaces of the bank base layer (1); an isolation layer (4) covers the upper surface of the modified asphalt coating and covering layer (2); an isolation layer (5) covers the lower surface of the modified asphalt coating and covering layer (3); each modified asphalt coating and covering layer is prepared from the following raw materials in percentage by mass: 38 to 44 percent of 90# asphalt, 11 to 17 percent of 200# asphalt, 5 to 8 percent of polypropylene, 1 to 3 percent of SBS, 4 to 6 percent of APAO, 2 to 3 percent of high-temperature modifiers, 15 to 17 percent of modification powder and 10 to 15 percent of filling materials.
