A No.1 frame aluminum profile and a No.2 frame aluminum profile are fastened into an integrated profile and form a left air-conditioner box plate together with an outer panel, an inner panel, foaming polyurethane and foamed rubber; a No.3 frame aluminum profile and a No.4 frame aluminum profile are fastened into an integrated profile and form a right air-conditioner box plate together with the other outer panel, the other inner panel, the other foaming polyurethane and the other foamed rubber; and the two air-conditioner box plates are fixedly connected to form plane fit through bolts and nuts. The aluminum-plastic composite type air-conditioner box with the plane fastening structure disclosed by the invention overcomes the defects of insufficient rigidity of an air-conditioner box body, low bearing static pressure, high deformation rate, poor heat insulation and preservation effects, cold bridge and the like. According to the aluminum-plastic composite type air-conditioner box with the plane fastening structure disclosed by the invention, the air leakage rate is reduced; the cold bridge can be avoided by an aluminum-plastic composite profile; deformed steel is inserted to the profile so as to greatly enhance the rigidity of the profile and be capable of resisting positive and negative pressures; after oppositely spliced, the profiles can be inserted to an aluminum alloy cover plate without exposing screws so as to be beneficial to the application of high-end purification and enhance the strength of the air-conditioner box; and moreover, the rigidity of the air-conditioner box is further strengthened by an internal reinforced rib and an external reinforced rib.

High-performance cement mortar board built-in lightweight ecological material T-shaped thermal insulation and load-bearing blocks
ActiveCN104005511BHigh strengthReduce weightConstruction materialEcological environmentThermal insulation
Relating to the field of building construction, the invention provides a high performance cement mortar board embedded light ecological material T-shaped thermal insulation and load-bearing block. According to the invention, steel wire mesh mortar boards and a light ecological material are combined together to constitute the composite thermal insulation and load-bearing block. The steel wire mesh mortar boards have the characteristics of high strength, good durability, low cost, convenient production and use, etc. The light ecological material is mainly light ecological concrete, which has better durability than ordinary concrete, has ecological environment coordination, can alleviate the earth and ecological environment load, realizes recyclable use of non-renewable resources, and also has good use functions. In addition to the advantages of the two materials, the thermal insulation block also has the characteristics of convenient construction, non cold bridge between horizontal blocks, etc., and the steel wire mesh mortar boards on two sides of the block can play a template role during pouring of concrete.

Insulated airtight breeding room
InactiveCN105507474BImprove liquidityAvoid corrosionBuilding roofsRoof improvementPurlinInsulation layer
The invention discloses a single-cavity, double-insulation and airtight roof system and a breeding house. It mainly aims at the problems of poor airtightness and heat-insulation performance of steel structures in the prior art, and proposes a single-cavity, double-insulation, and airtight roof. The single The double-cavity thermal insulation closed roof includes an upper thermal insulation layer arranged on the upper surface of the roof beams and a lower thermal insulation layer arranged on the lower surface of the roof beams; Steel wire mesh, glass wool and profiled steel plate, the lower insulation layer includes a technical solution of waterproof layer, glass wool, roof purlins and profiled steel plate arranged in sequence from top to bottom. The single-cavity, double-insulation and airtight roof system and the breeding house of the present invention realize good sealing and heat preservation on the top of the building. The single-cavity, double-insulation and airtight roof system and the breeding house of the present invention realize the inner leveling of the roof inside the building, so that the air flow at the roof is not blocked, and the air circulation inside the building is strengthened.
