The invention belongs to the field of building materials and construction technologies and relates to nano foamed concrete, a reinforced insulation wallboard and a preparation method of the reinforced insulation wallboard. The nano foamed concrete disclosed by the invention is prepared from the following ingredients in parts by weight: 100 parts of cement, 0.1-5 parts of desulfurized oil coke ash residue, 0.012 part of waterproofing agent, 10-30 parts of fly ash, 0.1-6 parts of superplasticizer, 50-200 parts of water, 1-20 parts of foamer and 0.01-5 parts of nano wave absorbing agent. Thus, when a wallboard product, prepared by embedding steel wire meshes in the nano foamed concrete disclosed by the invention, is applied nearby airports, docks, navigation marks, television stations and receiving stations or applied to concrete-based retaining walls of electromagnetic wave interference preventing scientific research departments, precise instrument plants and information leakage prevention high-grade buildings of national confidential units and the like, the most basic physical, mechanical, heat preservation and heat insulation properties are guaranteed on one hand, and the wallboard product has the capabilities of lowering noise and insulating sound on the other hand.

The invention discloses a heat insulation and cold insulation method of a liquefied gas low-temperature tank. Insulation plates with joggling structures are connected with each other in a joggled manner; a whole insulation structure is formed on the surfaces of tanks; all the insulation plates are fixedly connected with the tanks through fixed brackets; and the tanks are correspondingly provided with bolts in threaded connection with the fixed brackets. The joggled surfaces of the insulation plates are sealed by using hard polyurethane foam plastics in an injection foaming manner; and the outer surfaces of the joints are sealed by silica gel. The insulation plates include a first insulation layer, a second insulation layer and a third insulation layer arranged in sequence; the three insulation layers are arranged in a staggered manner; the joggling structures are formed on all four side surfaces; the adjacent insulation layers are connected in a bonding manner through low-temperature glue; and an outer protection layer is arranged on the upper surface of the first insulation layer. The method has the advantages of wide application range, safety, reliability, excellent closing performance and convenience for safety maintenance.

The invention discloses an improved anchoring part device. The improved anchoring part device comprises a fixing supporting part, a heat insulating piece is arranged on the top face of the fixing supporting part, and a lower fixing piece is fixedly connected to the fixing supporting part through bolts. The heat insulating piece is clamped between the lower fixing piece and the fixing supporting part. The fixing supporting part is fixedly connected to a wall through bolts. The front end of the lower fixing piece extends out of the fixing supporting piece and is bent downwards to form a lower inserting and connecting part, and the middle of the lower fixing piece is provided with a limiting hole and a gap controlling piece bent upwards. The middle of an upper fixing piece is provided with a fixing inserting and connecting piece bent downwards. The fixing inserting and connecting piece is inserted and clamped in a corresponding limiting hole of the lower fixing piece in a sleeving mode. The gap controlling piece is pressed on the bottom face of the upper fixing piece, and the front end of the upper fixing piece is provided with an upper inserting and connecting part bent upwards. The improved anchoring part device is simple in structure and convenient to install, the distance between an upper heat preservation plate and a lower heat preservation plate can be guaranteed, installing requirements for different gap widths are met, and the anchoring strength is guaranteed.

The invention relates to a directly-buried prefabricated independently-sealed steam tube with a tube bundle leakage warning function and a heat-insulation layer, and a method for manufacturing the directly-buried prefabricated independently-sealed steam tube. The directly-buried prefabricated independently-sealed steam tube comprises a sealed corrugated tube assembly, a steel guide tube, the heat-insulation layer, a plurality of leakage warning indicator tubes, an outer protective steel tube assembly, a corrugated tube assembly for a steel guide tube port and a working steel tube. The sealed corrugated tube assembly is hermetically welded with one end of the steel guide tube, the heat-insulation layer is arranged on the outside of the steel guide tube, the leakage warning indicator tubes transversely penetrate a space between the steel guide tube and the outer protective steel tube assembly, the corrugated tube assembly for the steel guide tube port is nested in a gap between the steel guide tube and the sealed corrugated tube assembly, and the working steel tube is nested in the steel guide tube. Compared with the prior art, the directly-buried prefabricated independently-sealed steam tube and the method have the advantages that the directly-buried prefabricated independently-sealed steam tube is provided with the permanent heat-insulation layer and is independently sealed, so that the heat-insulation performance of the heat-insulation tube can be guaranteed for a long time; overtemperature-preventive measures are adopted for the outer surface of the directly-buried prefabricated independently-sealed steam tube, and accordingly the directly-buried prefabricated independently-sealed steam tube is long in service life; the directly-buried prefabricated independently-sealed steam tube has port leakage warning and tube bundle positioning functions, so that a leakage state can be monitored in real time; the directly-buried prefabricated independently-sealed steam tube is provided with the corrugated tube assembly for the steel guide tube port and is convenient to mount.

The invention relates to a construction composite wall building block which comprises a composite layer and a core layer arranged in the composite layer, wherein a protective layer and a solar slab are orderly arranged on outer side of the composite layer, a cellular hollow cavity is arranged in the core layer, the left side end surface and the upper side end surface of the wall building block are provided with building block bulges, and the right side end surface and the lower side end surface are provided with building block grooves matched with the building block bulges; the construction composite wall building block has the advantages of being light in weight, high in utilization rate, good in sound insulation, water resistance and thermal insulation and heat preservation performances, high in construction efficiency, good in decorative finishing performance, low in cost, good in environment protection performance and energy conservation, good in fire resistance and good in bearing capacity, and capable of satisfying the demands of actual construction technology efficiency and high comprehensive performance of building.
