The invention provides a water resistance and thermal insulation outer wall building block with a water drainage structure. The water resistance and thermal insulation outer wall building block comprises a cuboid polystyrene core mold. Six thin reinforced concrete layers are poured on the six surfaces of the polystyrene core mold correspondingly to form the outer wall building block filled with thermal insulation materials; and the upper edge of the outer wall face of the outer wall building block is concaved downwards to form a notch, the lower edge of the outer wall face of the outer wall building block is provided with a lower buckle extending downwards, and the lower buckle is in overlap joint with a notch in the upper end of an adjacent outer wall building block under the outer wall building block, so that a horizontal gap between the two vertically adjacent outer wall building blocks is sealed. Vertical grooves are formed in the left side wall and the right side wall of the outer wall building block correspondingly, and the vertical grooves and vertical grooves formed in the side walls of the left and right adjacent outer wall building blocks form vertical water drainage hole passages. The outer wall building block is provided with the water drainage structure and is capable of draining water leaked from the outer wall face through the water drainage hole passages; and the outer wall building block has the advantages of being light in weight, good in water resistance and thermal insulation effect, simple in operation, low in cost, low in brickwork labor and the like.

The invention relates to a novel waterproof insulation roof building material and preparation method thereof, in particular to a natural stone PU waterproof insulation board and method for preparing natural stone PU waterproof insulation board by applying polyurethane foam spraying technique. The natural stone PU waterproof insulation board takes natural stone as a basement layer; wherein hard polyurethane foam layer is arranged on one surface of the natural stone at least, and the surface of the hard polyurethane foam layer is covered with a waterproof interface layer. The invention provides a novel building material with both waterproof function and heat insulation function, the natural stone and waterproof and heat insulation processing are integrated, waterproof insulation performance is good, construction is convenient, and safety factor after construction is high, thus eliminating the heat bridge of outer wall at a large extent, which is impossible for inner heat insulation, being widely applied to energy conservation waterproof insulation in the building field and having a wide market prospect.

A water-proof insulating decorative ceramics-like composite plate is composed of base plate and decorative layer with water-proof and insulating functions. The said base plate is made of cement, fine sand, broken sand and water through mixing. The said decorative layer is made of white jade sand, white cement, high-weight ceramics-like additive powder and polyethylene adhesive through mixing. Its advantages are beautiful and smooth appearance, high weatherability and flexible strength, and better water-proofing and insulating performance.

The invention provides a plastic foam cement composite insulation plate directly laid on a building level surface, as well as a manufacture and construction method thereof. The plastic foam cement composite insulation plate comprises a plastic foam insulation bottom die and a bearing concrete structure which is poured on the plastic foam insulation bottom die, wherein a plurality of grooves which are staggered one another are formed in the upper surface of the plastic foam insulation bottom die; vertical ducts are formed in the joints of the plurality of staggered grooves and lead to the lower surface of the plastic foam insulation bottom die; and the diameters of the lower end parts of the vertical ducts are increased; and the bearing concrete structure comprises legs which are poured in the vertical ducts, ribs poured in the grooves and a surface layer poured on the upper surface of the plastic foam insulation bottom die. The plastic foam cement composite insulation plate is a novel construction material with waterproof and heat-insulation double functions, and has the advantages of light weight, good waterproof and heat-insulation effect, simple operation, low cost, low labor consumptionand the like.

The invention provides a sealing strip for glass. The sealing strip comprises a body, the body comprises a short sealing strip, a long sealing strip, cavities, long rubber strips, clamping pieces andshort rubber strips, the long sealing strip is arranged at the upper end of one side of the body, the short sealing strip is arranged at the lower end of one side of the body, the long rubber strips,the clamping pieces and the short rubber strips are sequentially arranged on the other side of the body from the upper end to the lower end, and two closed cavities are arranged in the middle of the body. The sealing strip is simple in structure, good in water and heat insulation effect and good in sealing effect, and the matching tightness of the sealing strip and glass is high.
