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 an entire-underground cable tunnel safety manhole being used also as a ventilation shaft, which pertains to the technical field of power supply and distribution circuits and comprises an underground firewall with a door, an aboveground firewall, a fire door, a propeller fan, a fire damper, a safety manhole, a vertical ladder, a stair hall, a sump pit and a dredge pump; wherein the safety manhole is also used as a ventilation shaft and adopts an entire-underground type. The entire-underground cable tunnel safety manhole has the advantages that: as the internal structure of the ventilation shaft is optimized, the requirements of ventilation, drainage, fire prevention and routing inspection of the cable tunnel are satisfied, and the entire structure of the ventilation shaft is arranged underground, thus solving the problem of the overall beautiful appearance of a factory and effectively reducing the construction cost. The channel and the ventilation opening of the ventilation shaft are integrated into one, thus being capable of being flexibly arranged without affecting the arrangement of other facilities on the ground in the factory district.

Disclosed is a temporary protective peelable waterborne screen printing ink which contains the following ingredients(based on weight percentage):40-80 waterborne polyurethane resin, 0.1-2 waterborne foam killer, 0.1-2 waterborne dispersant, 0.1-2 waterborne wetting agent, 4-20 humectant, 5-40 filler and 0.1-5 thickening agent. All the ingredients of the waterborne screen printing ink are waterborne materials and are of excellent elasticity and intensity, so the waterborne screen printing ink can be easily peeled from a panel after being sprayed and painted and is of good solvent resistance after being filmed, thus ensuring that dope can not permeate the screen printing ink layer to erode the plastic panel.

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.
