Problems solved by technology

High cost: The panels and side panels bear the positive and negative wind pressure, self-weight and the weight of the airtight bag and possible collisions behind the insulation board wall. They need to have corresponding strength and rigidity. After the bag is inflated, it must maintain the set shape under the action of the falling force of its own weight. It also needs corresponding strength a

Embodiment 1

[0032] Such as figure 1 , 2 As shown, the metal gas insulation board provided by the present invention is composed of an upper metal plate 1, a lower metal plate 2, and a gas chamber 3. The sealing edge of the upper metal plate 1 and the sealing edge of the lower metal plate are sealed and connected to form the gas chamber 3. , the cavity wall of the gas chamber 3 is provided with an air filling hole 19, the inner edge of the upper metal plate 1 and the lower metal plate 2 sealing edge is provided with a welding position 6, and between the upper metal plate 1 and the lower metal plate 2 sealing edge is provided Metal or its alloy sealing strip 7 with a melting point of 90°C-385°C, such as tin and its alloys, lead and its alloys or low-temperature zinc alloys, etc., in order to increase the thickness of the sealing strip 7, a There is a concave airtight strip groove 9, so that a welding groove 12 is formed on the outer surface of the welding position, and an airtight strip 7 i...

Embodiment 2

[0034] Such as image 3 As shown, the gas cavity 3 of the metal gas insulation board provided by the present invention is provided with a partition layer 13, and a support column 15 is provided between the partition layers 13, and the support column 15 can increase the wind pressure resistance of the plate body; one side sealing edge There is a buckle groove 10-1 formed by the flanging facing outward and leaving a gap 16, and the flanging 10-2 with the sealing edge on the other side facing inward and leaving a gap 16, the buckle groove 10-1 and the turning groove formed by the flanging The buckle groove 10-2 formed by the edge is corresponding. During installation, the buckle groove 10-1 formed by the flanging is buckled into the buckle groove 10-2 formed by the flanging, and the rest of the structure is the same as that of the first embodiment.

Embodiment 3

[0036] Such as Figure 4 As shown, the outer surface of the metal gas insulation board provided by the present invention is provided with a decorative protective layer 20, and the decorative protective layer 20 is buckled on the anti-seepage convex strip 14, or fixed to the welding sealing edge 17 or In the mounting hole 18 of the buckle groove 10, all the other structures are the same as in the first embodiment.

Abstract

The invention discloses a metal-gas heat-insulation plate and a method for manufacturing the same. The metal-gas heat-insulation plate is characterized in that an upper metal plate and a lower metal plate are connected with each other in a seal fit manner to form a gas cavity, inflation holes are formed in the walls of the gas cavity, weld positions are arranged at the inner edges of seal edges of the upper metal plate and the lower metal plate, closing strips are arranged between the seal edges of the upper metal plate and the lower metal plate, are positioned on the outer sides of the weld positions and are made of metal with melting points ranging from 90 DEG C to 385 DEG C or alloy of the metal, and the closing strips and the seal edges of the upper metal plate and the lower metal plate are integrally adhered with one another and are sealed. The metal-gas heat-insulation plate and the method have the advantages that high gas tightness of the metal-gas heat-insulation plate can be kept for a long time in severe natural environments, and the metal-gas heat-insulation plate is high in sealing strength and deformation resistance; the molten closing strips with ductility have certain deformation capacity, and accordingly the closing performance still can be perfectly kept when products deform due to factors such as temperature stress, wind load and the dead weight of plate bodies in the severe natural environments.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a metal gas insulation board for external wall insulation and a manufacturing method. Background technique [0002] Existing similar insulation boards mainly include: air insulation boards and fireproof hollow insulation boards. The air insulation board is composed of a core board and a panel compounded on the surface of the core board. The core board is an inorganic viscose corrugated board. A plurality of air insulation chambers are formed between them, and sealing parts are arranged at both ends of the air insulation chambers, so that the air insulation chambers become sealed air insulation chambers. Existence: The corrugated board of the core board connects the upper and lower panels to form a plate-shaped connecting rib, which has a large cold bridge effect and seriously affects the thermal insulation performance of the product. The fireproof hollow insulation board is co...
