The invention discloses a method for producing a cast-in-situ insulation roof, which comprises the technological process that a steel screen is welded on a purline, the purline is bound with the steel screen, then DFB lightweight aggregates are poured, blocks of polyphenyl plates are embedded in the DFB lightweight aggregates side by side, fiberglass meshes are respectively laid between the DFB lightweight aggregates on the upper and lower surfaces of the polyphenyl plates, after the DFB lightweight aggregates are completely poured, a trowel for levelling up is used for beating the DFB lightweight aggregates to solidify, and finally, mortar is used for plastering an anti-cracking layer top facing. According to the method, an outer building envelop and energy-saving insulation engineering are integrated to be completed at one step, the technology is simple, the application scope is wide, and the construction progress is accelerated. The method can be used for manufacturing an insulation roof which is light, has high-strength and good integral fire proofing, and is low in comprehensive cost.

The invention discloses a material on a tunnel drainage layer, which is characterized by comprising the raw materials with the following parts by weight: 100 parts of rubber particles, 20-50 parts of mineral wool fibres and 50-80 parts of VAE emulsion. The material adopts water conductivity of inorganic fibers, elasticity of waste vulcanized rubbers and cohesiveness of the VAE emulsion, and on the basis of better drainage property, has the leveling function to fill and level up upper concave pits and has the elastic function to be adaptive to deformation of the upper structure, changes the construction technology, can carry out direct injection, improves the construction efficiency and reduces the labor intensity of workers.

The invention discloses a backcut changeover cross beam of a unitized curtain wall. The backcut changeover cross beam of the unitized curtain wall comprises a cross beam framework. The upper surface of the cross beam framework is a channel steel junction surface; the left side of the cross beam framework is provided with an aluminum plate skeleton connecting part; the lower surface of the cross beam framework is provided with a changeover cross beam hook; the hooking part of the changeover cross beam hook forms an inclination towards the inner side and along the horizontal direction; and the right side of the cross beam framework is provided with a pressing plate assembly slot. According to the backcut changeover cross beam of the unitized curtain wall, the construction flow of a general curtain wall is changed, i.e. a decoration panel of a cornice is firstly installed, and a working face can be totally spread to engineering to realize cross operation; the cross operation is not limited by the construction sequence, and parallel construction can be performed, therefore, the construction progress is greatly increased. An interlayer backcut changeover cross beam of the unitized curtain wall and a cornice aluminum plate skeleton are combined to form an integral seal, therefore, not only can the functional requirement of the cornice aluminum plate skeleton be met but also the functional requirement that the cornice aluminum plate skeleton is combined with the interlayer backcut changeover cross beam of the unitized curtain wall can be met.
