Abstract
The utility model belongs to the field of aviation environmental control and particularly relates to a heat insulation connecting structure, which comprises a plurality of connecting elements 1, a heat insulation plate 2 and a heat insulation plug 3, wherein the connecting elements 1 are embedded into the heat insulation plate 2, then, the head parts of the connecting elements are exposed out, and the heat insulation plug 3 seals the connecting elements 1. The heat insulation connecting structure adopts fastening elements for layered staggered connection. Through adopting the connecting form, the fastening elements do not penetrate through the whole plate layer structure, a cold bridge cannot be formed, the heat insulation effect is ensured, the length of the fastening elements is short, the stress deformation is small, the rigidity is good, the service life is long, the fastening elements are embedded into the heat insulation layer in advance during the installation, then, the layer-by-layer assembly is carried out, the operation is simple, and the installation error is small.
Description
Technical field
The utility model belongs to aviation ring control field, particularly relates to a kind of heat-insulating connecting structure.
Background technique
Existing insulating sandwich structure adopts the fastening piece penetration to connect.Under this Connecting format: fastening piece penetrates whole layer structure and forms cold bridge, affects effect of heat insulation; Fastening piece length is longer, and stress and deformation is larger, affects rigidity and life-span; Punch and connect after needing during installation all flaggies are concentrated, being unfavorable for that operation and alignment error are large.
Summary of the invention
The purpose of this utility model is: a kind of heat-insulating connecting structure of lightweight is provided, and effect of heat insulation is remarkable.
The technical solution of the utility model is: a kind of heat-insulating connecting structure, comprise several links 1, and thermal baffle 2 and heat insulation plug 3, described link 1 expose head after being embedded in thermal baffle 2, and described heat insulation plug 3 is with link 1 sealing.
Described link 1 is bolt.
Described thermal baffle 2 and plug are plank.
Described several links 1 interlock and are closed in thermal baffle 2.
The utility model has the advantages that: the utility model adopts fastening piece layering alternating expression to connect.Under this Connecting format: fastening piece does not penetrate whole layer structure, can not form cold bridge, guarantees effect of heat insulation; Fastening piece length is shorter, and stress and deformation is less, and the good rigidity life-span is long; In advance fastening piece is embedded into thermal-protective coating during installation, and then layering assembles, simple to operate, alignment error is little.
Description of drawings
Fig. 1 is traditional heat-insulating connecting structure schematic diagram;
Fig. 2 is the utility model structural representation.
Wherein, 1-link, 2-thermal baffle, 3-plug, 4-sheet metal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details, sees also Fig. 1 to Fig. 2.
As shown in Figure 1, be traditional heat-insulating connecting structure, link 1 passed sheet metal 4 and thermal baffle 2, was connected on force transferring structure.There are two large drawbacks in this kind heat-insulating connecting structure, and at first link 1 is exactly cold bridge, and thermal loss is large, moreover owing to considering that effect of heat insulation generally all can make thermal baffle 2 thickening as far as possible, link 1 just must lengthen, and length lengthens, stress and deformation increases, and affects rigidity and life-span.
As shown in Figure 2, be the utility model structural representation, a kind of heat-insulating connecting structure comprises several links 1, and thermal baffle 2 and heat insulation plug 3, described link 1 expose head after being embedded in thermal baffle 2, and described heat insulation plug 3 is with link 1 sealing.The quantity of link 1 is staggered in heat insulation skeleton, between not contact, quantity can be regulated by concrete use condition, link 1 inserts in heat insulation skeleton, can shorten the length of link, stress deformation is little, strengthens link rigidity and working life.Heat insulation plug can completely cut off the generation of cold bridge.
Described link 1 is bolt.
Described thermal baffle 2 and plug are plank.
Described several links 1 interlock and are closed in thermal baffle 2.
