Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a low-energy aerogel composite external formwork. Background Technology

[0002] Building insulation materials are commonly used in building construction. They reduce heat exchange between the interior and exterior of a building, ensuring a more suitable indoor temperature environment. With the promotion of low-energy green buildings, the requirements for the thermal insulation performance of building insulation materials are becoming increasingly stringent.

[0003] With the upgrading of building insulation materials, composite external formwork has been widely used. Existing composite external formwork typically consists of multiple vacuum insulation panels and an outer protective shell. To facilitate drilling and installation, a certain gap must be left between adjacent vacuum insulation panels. Currently, this gap is filled with a coating grout. However, the coating grout has a higher thermal conductivity than the vacuum insulation panels, which creates thermal bridges between adjacent panels, reducing the insulation performance of the composite external formwork. Therefore, a low-energy aerogel composite external formwork is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-energy-consumption aerogel composite template to solve the problems existing in the prior art mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-energy aerogel composite outer template includes several vacuum insulation panels, aerogel felt, and a protective shell. The several vacuum insulation panels are laid out in the same plane at equal intervals. Aerogel felt is provided in the gap between adjacent vacuum insulation panels. The vacuum insulation panels and aerogel felt are wrapped with a protective shell formed by curing a coating slurry.

[0007] Preferably, the protective outer shell surface is provided with anchor bolt mounting holes and tie bolt mounting holes, which pass through the area where the aerogel felt is arranged.

[0008] Preferably, the aerogel felt is connected to the side of the vacuum insulation panel by means of adhesive bonding.

[0009] Preferably, the gap between adjacent vacuum insulation panels is set to 20-50 mm.

[0010] Preferably, the protective shell is made of a thermal insulation mortar with a fire rating of A.

[0011] Preferably, the vacuum insulation panel is made by vacuum sealing a core material covered with a high-barrier film.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates aerogel felt in the gap between adjacent vacuum insulation panels. The aerogel felt has a low thermal conductivity, which can effectively reduce the thermal bridging effect of the mounting holes and improve the thermal insulation effect of the composite outer template. Furthermore, the aerogel felt can be perforated, facilitating the installation and fixing of the composite outer template. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1-3 The present invention provides the following technical solution:

[0020] A low-energy aerogel composite outer template includes several vacuum insulation panels 1, aerogel felt 2, and a covering shell 3. The vacuum insulation panels 1 are made by vacuum sealing a core material covered with a high-barrier film. The core material is made of silica or glass fiber. The high-barrier film includes an outer film, a middle film, and an inner film arranged sequentially from the outside to the inside. The outer film is made of nylon or PVC. The middle film is made of at least one of VMPET film, PVDC film, PVA film, PP film, and PVC film. The inner film is made of PE material. The specific structure of the vacuum insulation panels 1 can improve the thermal insulation effect of the entire composite outer template.

[0021] Several vacuum insulation panels 1 are laid out in the same plane at equal intervals. The gap between adjacent vacuum insulation panels 1 is set to 40mm. The purpose of setting the gap between adjacent vacuum insulation panels 1 is to facilitate drilling and installation of the composite outer template. The gap can be set according to the specific building construction requirements.

[0022] An aerogel felt 2 is provided in the gap between adjacent vacuum insulation panels 1. The aerogel felt 2 is connected to the side of the vacuum insulation panel 1 by adhesive. By providing the aerogel felt 2 in the gap between adjacent vacuum insulation panels 1, the aerogel felt 2 has a low thermal conductivity, which can effectively reduce the thermal bridge effect, improve the thermal insulation effect of the composite outer template, and can be perforated to facilitate the installation and fixing of the composite outer template.

[0023] The vacuum insulation panel 1 and aerogel felt 2 are wrapped with a protective shell 3 formed by the curing of a coating slurry. The protective shell 3 is made of a thermal insulation slurry with a fire rating of A, such as a slurry made of flame-retardant expandable polystyrene foam particles, hydraulic inorganic cementitious materials, polymers, and additives. The protective shell 3 made of thermal insulation slurry with a fire rating of A can protect the vacuum insulation panel 1 and aerogel felt 2. Moreover, the protective shell 3 has excellent properties such as high compressive strength, moisture resistance, light weight, corrosion resistance, super anti-aging properties, and low thermal conductivity, and can be used as a formwork for pouring concrete for building walls.

[0024] The protective shell 3 has anchor bolt mounting holes 4 and tie bolt mounting holes 5 on its surface. The anchor bolt mounting holes 4 and tie bolt mounting holes 5 pass through the arrangement area of ​​the aerogel felt 2. Compared with the protective shell 3 formed by the curing of the coating slurry, the aerogel felt 2 has a lower thermal conductivity. When the anchor bolts are used to fix the composite outer template through the mounting holes 4, the aerogel felt 2 can also reduce the temperature transfer between the anchor bolts and the anchor bolts, further improving the thermal insulation effect of the composite outer template.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
