Three. summary of the invention
3.1. object and technical approach:
The present invention mainly solves high-efficiency insulated performance and material fireproof performance (A grade standard) problem of heat insulating material in current external wall Surgery therapy energy conserving system, solve and improve that the support of heat insulating material for external self is stressed (can select finish material arbitrarily on the face of outer heat preservation system, the diversity of exterior wall finish material is made to select not restricted) problem, solve and guarantee that heat-insulation system is by high heat conduction member all standing (as: outdoor machine of air-conditioner shelves exposed all on skin, balcony slab and breast board, rain pipe and air conditioner condensation water pipe fixing generation cold bridge) problem, solve the safe and reliable problem that heat insulating material is installed in anchoring, and then make external wall Surgery therapy energy conserving system reach the same life-span with major structure of construction.
The present invention selects the material that existing heat-insulating property is strong, fireproof performance grade is high to become combined type thermal-insulating plate with the disconnected hot Component composition developed in the present invention.Disconnected hot component has high thermal resistance, strong supporting capacity, refractoriness is good and weatherability is strong composite material are made.Combined type thermal-insulating plate has disconnected hot component to be clipped in the middle of two-layer heat insulating material to form, and the special tectonic point on disconnected hot component can be utilized to carry out build-in live heat insulating material.Two surfaces of plate are reserved respectively can connect the support node of exterior rendering reinforcing rib and the fixed support for anchoring outer wall structure of building, after the external loads power acted on combined type thermal-insulating plate is born by the hot component that breaks, and is passed on major structure of construction.Create the art feature that heat insulating material is applied in complex with the respective functional characteristic of disconnected hot component.This technical assemblage characteristic, can guarantee high-efficiency insulated energy saving and the security reliability of External Thermal Insulation System.
3.2. the technical characteristic of the existing external wall Surgery therapy energy conserving system in application has following several:
1. exterior wall is pasted the external wall Surgery therapy energy conserving system of (local adds nylon expandable nail) organic compound class foaming thermal-insulating (as: foamed polystyrene board, polyurethane foam board or foam-in-place).To it is characterized in that first being pasted onto by heat insulating material on external wall (local adds nylon expandable nail), outer cover glass fibrous mesh cloth, execute multilayer book again and to plaster overcoat.Although the heat conduction system of organic compound class foaming thermal-insulating is very low, high insulating efficiency is high.But unfortunately material self fireproof performance is low, after adding flame-retardant materials, the grade of its fireproof performance can only reach B1 level, and material self-strength is low, rigidity is little, only relying on point type stickup or sliver shape to paste and locally add nylon expandable nail anchorage style is fixed on wall, under wind load repeated action over a long time, lasting degree of safety still difficulty is completely guaranteed, and directly cannot add facing load at its surface mount, in highrise building more difficult realize facade decoration materials variation.
2. exterior wall is pasted the external wall Surgery therapy energy conserving system of (local adds nylon expandable nail) inorganic matter foaming thermal-insulating (as: foamed glass brick, foamed concrete plate (block), alumina silicate powder mixed foaming plate).To it is characterized in that first being pasted onto by heat insulating material on external wall (local adds nylon expandable nail), outer cover glass fibrous mesh cloth, execute multilayer book again and to plaster overcoat.Although the fireproof performance grade of heat insulating material reaches A level, but the coefficient of thermal conductivity of these materials comes much higher relative to organic compound class foaming thermal-insulating, for the thickness meeting heat preservation energy-saving requirement use is thicker, and the characteristic of these heat insulating materials is more crisp, easily fragmentation, stickup and the local of bulk area add the method for nylon expandable nail anchoring, under wind load repeated action over a long time, degree of safety still difficulty is completely guaranteed.Again at its surperficial affixed finish material, insulation energy-saving system is more easily damaged, and be applied in highrise building, degree of safety is also more difficult to ensure card, is therefore used in fire barrier at present.
