The invention relates to a high-heat-insulation sandwich construction wall cement foam and a preparation method thereof. The foam is prepared through using fast-hardening sulphoaluminate cement, ordinary Portland cement, fly ash, silicon ash, lithium carbonate, calcium stearate, methyl cellulose, dispersible latex powder, engineered fibers, a water reducer, water and hydrogen peroxide. The high-heat-insulation sandwich construction wall cement foam has the advantages of good concreting effect, no dead angle problems, stable performances, long life, ageing tolerance, flame retardation and fire prevention, good heat insulation effect, energy saving, environmental protection, non-toxicity, and no pollution; and the preparation method has the advantages of simplicity, easy operation, small influence of external factors, and wide application range.

The invention discloses a pitched roof mounting system for a solar thermal collector and a construction method of the pitched roof mounting system. The system comprises a pitched roof and the solar thermal collector arranged on the pitched roof, wherein the pitched roof consists of a structural layer, a cement mortar leveling layer, a waterproof pad layer, a heat preservation water drainage layer, transverse tile hanging wood bars and roof tiles, wherein the heat preservation water drainage layer consists of a heat preservation plate, wood carrying brackets I, longitudinal downstream wood bars and an aluminum foil coiled material; two-side concave-shaped water drainage ditches are formed between the solar thermal collector and the longitudinal downstream wood bars on the left side and the right side of the solar thermal collector; an upper-side concave-shaped water drainage ditch is formed between the solar thermal collector and transverse lap-joint wood bars; a lower-side concave-shaped water drainage ditch is formed between the solar thermal collector and the roof tiles on the lower side of the solar thermal collector. According to the system and the construction method which are disclosed by the invention, the construction technology is changed; the solar thermal collector can be firmly and stably mounted; the pitched roof has energy-saving and ventilating effects; the heat insulation and preservation efficiency of the pitched roof can be improved, and the surface of a building is attractive.

The invention discloses a charging device and a charging joint thereof. The charging joint comprises a fixing part, a conducting part, a U-shaped part, at least one shielding plate and a bearing plate, wherein the conducting part, which is extended from one end of the fixing part, is bent to form at least one arc part; the U-shaped part is extended from the other end of the fixing part in a bent manner; the U-shaped part and the conducting part are bent to two sides of the fixing part; the at least one shielding plate is arranged at the bearing part; the bearing part is extended from the U-shaped part; and when the bearing part is propped via an external force, the bearing part is shifted from a first position to a second position.
