The invention discloses a plastered insulated compound wall body with nets on both sides, which is used for solving the problem of the influence of a thermal bridge of an energy-saving wall body opening on building energy conservation. The plastered insulated compound wall body comprises a building main body structural bearing member, a core layer, a netlike tensile material, outdoor steel bars, a support overhanging beam or plate, indoor steel bars, doors and windows, a protection layer, an outer side protection layer of the doors and windows, an inner side protection layer of the doors and windows and internal and external tension wires, wherein the indoor vertical steel bars are anchored with a building main body structure; the outdoor vertical steel bars are fixed with the support overhanging beam or plate; the indoor and outdoor horizontal steel bars are fixed with the indoor vertical steel bars and the outdoor vertical steel bars respectively; the internal and external tension wires are used for connecting the outdoor steel bars with the indoor steel bars; the netlike tensile material is fixed with the indoor and outdoor steel bars; the core layer is arranged between the outside of a framework and an inner frame; protection layers are arranged on both sides of the core layer; the doors and windows are arranged on an opening core layer; and both sides of the doors and windows are provided with the outer side protection layer of the doors and windows and the inner side protection layer of the doors and windows. In the plastered insulated compound wall body with the nets on both sides, a heat insulating and bridge breaking structure is adopted, so that the energy-saving and heat insulating effects of the wall body are greatly enhanced.

The invention relates to a preparation method of a polymer composite foam material. The method comprises the following steps: 1, banburying, namely mixing the raw materials at a certain mass ratio, then adding the mixture into an internal mixer, and performing internal mixing at a temperature of 90+ / -5 DEG C for 6-8 hours; 2, discharging the mixture to a single screw extruder and extruding; 3, feeding a panel to a high-temperature foaming furnace and performing curing foaming; 4, cutting and tailoring the panel into sheets, so as to prepare the product. The prepared material disclosed by the invention has the characteristics of being good in heat insulation and heat preservation effects, light in weight, environment-friendly and non-toxic, convenient to install, and low in price, can achieve the A grade of flame retardant requirements, and can be applied to the fields of high-rise buildings, residential houses, ship engineering, cold storage, petrochemical engineering, chemical engineering, defense-related science and technology, cold insulation engineering of military industry and the like.

The invention provides a pre-fabricated external insulation board, a thermal-insulating wall formed by assembly thereof and a construction method of the thermal-insulating wall. One pre-fabricated external insulation board comprises an insulation board, a steel wire mesh and an anti-cracking mortar board. Upper and lower edges and four opposite angles of one insulation board are provided with transversely-connected grooves for dividing the above insulation board to be an outer surface layer and a wall-leaning layer. The steel wire mesh is fixed onto the outer surface layer of the above insulation board by means of fixing steel nails. Upper, lower, left and right edges of the steel wire mesh are larger than upper, lower, left and right edges of the wall-leaning layer of one insulation board. The anti-cracking mortar board is formed in such a manner that the outer surface of one insulation board, corresponding to the steel wire mesh, is painted with ant-cracking mortar. The thermal-insulating wall comprises a concrete external wall, longitudinal connecting pieces and transverse connecting pieces. By means of the longitudinal connecting pieces and the transverse connecting pieces, pre-fabricated external insulation boards are arrayed to be fixed onto the concrete external wall such that the thermal-insulating wall is formed.

The invention relates to heat preservation doors and windows with conveniently-dismounted attached frames of the doors and windows. The heat preservation doors and windows comprise heat preservation doors and windows as well as attached frames of the doors and windows, wherein the attached frames of the doors and windows are connected with a building structure with openings to be mounted with the doors and windows through expansion bolts; the attached frames are provided with pitch-adjustable T-shaped pieces; the heat preservation doors and windows are clamped with the attached frames through processed mounting clamping grooves which are arranged outside window frames and the pitch-adjustable T-shaped pieces having adjustable screws; and sealing strips are additionally arranged on the outer edges of the attached frames and used for ensuring the sealing between the doors and windows and the attached frames after the installation. The heat preservation doors and windows provided by the invention have the advantages of simple structure, convenience for material processing, simplicity for installation and strong adjustability, besides, the attached frames of the doors and windows are mounted outside the doors and windows through elastic, weather-resistant, formed and heat-insulating sealing strips, the conventional gluing sealing technology is discarded, so that the installation is simpler and more convenient, the sealing effect and service life of the doors and windows are largely improved and prolonged respectively, meanwhile the energy saving and heat preservation effects of the doors and windows are also improved; moreover, mounting holes are unnecessary to punch on the doors and windows, therefore the air tightness and water tightness of the doors and windows are improved, and the processing steps are reduced.

The invention relates to the field of roof waterproofing, and discloses a load-bearing diversion device, which includes a diversion device, a corner post and a load-bearing main cross bar. , raised tiles, moisture barrier film, flat iron and multiple clips, the raised tiles are set on both sides of the flat tiles, forming a saddle tile surface layer with the flat tiles, and the flat irons are set on the lower surface of the flat tiles and bonded On the flat tiles, the moisture-proof membranes are installed at the cornices on both sides of the saddle-shaped tiles, and the clips are fixed on the flat iron. The saddle-shaped tiles are supported by corner columns and main load-bearing horizontal bars. The present invention directly transmits the load from the upper part to the building structure through the corner columns and the load-bearing main crossbar, and uses clips to be arranged on the flat iron to clamp the tile ridge crossbar and the tile eave crossbar to ensure that the saddle tile After installation, it will not be easily displaced. At the same time, a moisture barrier film is provided on the outside of the tile eaves cross bar, which is connected to the side of the branch channel to prevent water droplets from splashing out of the branch channel and splashing on the roof to make water vapor.
