Fracturing bridge heat insulating energy-saving decorative board and frame thereof

Abstract

The invention relates to a broken bridge heat-insulated energy-saving decorated plate and a side frame used for the same. The decorated plate is provided with a panel (1), a base plate (2) and an insulated core plate (3); a section side frame (6) is in bonding connection with the section at the side part of the decorated plate; the section side frame (6) is a broken bridge heat insulated composite section side frame (6) which consists of a plastic section (61) on the lower part and a metal section (62) on the upper part; the metal section and the plastic section are in interference fit by a male and female face (62c) and embedded into a whole; an inner side wall (62a) of the metal section is in bonding connection with the panel and the section of the insulating core plate close to the upper part at one side of the panel; an inner wall surface (61a) of the plastic section is in bonding connection with the base plate (2) and the section of the insulated core plate close to the lower part at one side of the base plate; and a plastic section bottom surface (61b) which inwards turns by 90 degrees and is attached to the base plate (2) is arranged on the lower part of the section side frame (6). The invention can be produced industrially, is convenient to mount, can improve the sealing, waterproof and insulating performances of decorated curtain wall, save the energy and prolong the service life of the curtain wall.

Description

technical field [0001] The invention belongs to a building material, and in particular relates to a heat-preservation decorative board and a frame used for it to maintain, heat-preserve and decorate the exterior wall of a building. Background technique [0002] At present, one type of thermal insulation decorative board installed on the exterior wall of a building is provided with a panel and an insulating layer. The thermal insulation layer of this decorative board requires on-site foaming processing, and the work efficiency is low. In order to improve production efficiency, industrial production is usually adopted. This type of thermal insulation decorative board is equipped with a panel, an insulation layer and a bottom plate. The small plates for construction are combined and fixed on the outer wall of the building on site to form a large-area thermal insulation decorative panel curtain wall outside the wall. The thermal insulation decorative panel itself has thermal ins...

AI Technical Summary

Problems solved by technology

[0003] see figure 1 , which is a schematic structural diagram of the spliced ​​part of a single-layer aluminum plate (without a back plate). In the spliced ​​joint between the sections of adjacent plates (A1, A2), the outermost layer is a weather-resistant sealant (7), the sealant The inner part is thermal insulation material (8), and its shortcoming is: both sides of the outermost layer of sealant (7) are bonded and connected with adjacent plate sections respectively, and the section of the plate panel (1) with waterproof function on both sides is very small. Thin, only 0.6-1.5 mm thick, unable to form effective bonding, prone to degumming and water leakage, and moisture and water vapor infiltrating into the internal insulation material (8), which will greatly reduce the insulation performance and accelerate The aging of insulation materials shortens the service life

Its shortcoming is: In order to achieve the thermal insulation effect, there are two methods currently adopted: one is to paste the thermal insulation layer on the back of the aluminum plate during on-site construction or nail the thermal insulation layer plug into the cavity between the aluminum plate and the wall. The other is to press The size of the site needs to be cut into boards of different specifications in the factory. First, the edges are folded into a box shape, and then the polyurethane single-mode clip foaming process is used to inject a composite board shape. The process is complicated and cannot be flow-lined.

[0005] In order to overcome the above deficiencies, there are composite thermal insulation decorative panels produced by flowing water, but they can only be produced by one-way flowing water. During the production process, the longitudinal edges can be folded and wrapped to block the insulation layer, but the cross-section produced by transverse cutting cannot be used. Automatic edge wrapping can only be processed after cutting into plates. During processing, the insulation core board at the edge must be hollowed out, and then the panel is bent down to protect the section. The processing is troublesome and causes a waste of board resources. The frame itself is usually a metal material with a high thermal conductivity, which has no heat insulation effect on the interior, so it will still affect the thermal insulation performance of the joint parts
