Description

Technical Field

[0001] This utility model relates to the field of building insulation materials technology, specifically to a composite external formwork with high flexural load resistance. Background Technology

[0002] Composite external formwork is a new type of building material with excellent thermal insulation and waterproof / moisture-proof properties, and is widely used in building exterior wall insulation projects. Composite external formwork typically consists of a vacuum insulation panel and an outer layer of insulating mortar. Because the insulating mortar needs to be made of a material with low thermal conductivity, its flexural strength is poor. Composite external formwork is often damaged by bending forces during transportation and construction, resulting in significant losses. Furthermore, after installation, when the surface of building components is subjected to significant impact, the composite external formwork is also prone to deformation and damage, leading to air leakage and failure of the internal vacuum insulation panel, thus losing its thermal insulation capacity. Therefore, a composite external formwork with high flexural load-bearing capacity is needed to solve these problems. Utility Model Content

[0005] A composite external template with high flexural load resistance includes a vacuum insulation board and a thermal insulation mortar covering the outside of the vacuum insulation board. A fiberglass mesh is provided in the thermal insulation mortar on one side of the vacuum insulation board, and a steel wire mesh is provided in the thermal insulation mortar on the other side of the vacuum insulation board. Both the fiberglass mesh and the steel wire mesh are arranged parallel to the surface of the vacuum insulation board.

[0006] Preferably, the wire mesh is a galvanized wire mesh in which longitudinal and transverse wires are arranged at certain intervals and are perpendicular to each other and welded together at their intersections.

[0007] Preferably, the thickness of the insulation slurry covering one side of the wire mesh to the surface of the vacuum insulation board is h1, which is 12-30mm, and the thickness of the insulation slurry covering one side of the fiberglass mesh to the surface of the vacuum insulation board is h2, which is 10-20mm.

[0008] Preferably, the thickness b of the outer surface of the insulating slurry to the side surface of the vacuum insulation board is 10 mm.

[0009] Preferably, the surface of the fiberglass mesh is coated with a polymer material, which gives it alkali resistance.

[0010] Preferably, the outer protective shell formed by the coating insulation slurry is made of expandable polystyrene foam particles.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention effectively improves the impact and bending resistance of the composite formwork by setting fiberglass mesh and steel wire mesh in the insulation mortar covering the front and rear sides of the vacuum insulation board, reducing the breakage rate of the composite formwork during transportation and construction, and extending the service life of the composite formwork.

[0019] A composite external formwork with high flexural load resistance includes a vacuum insulation board 1 and a thermal insulation slurry 2 covering the outside of the vacuum insulation board 1. The vacuum insulation board 1 is 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, and the inner film is made of PE. The outer protective shell formed by the thermal insulation slurry 2 is made of expandable polystyrene foam particles. Through the combination of the vacuum insulation board 1 and the thermal insulation slurry 2, a composite external formwork for thermal insulation of the building can be formed.

[0020] A fiberglass mesh 3 is provided inside the insulation grout 2 located on one side of the vacuum insulation board 1. The surface of the fiberglass mesh 3 is coated with a polymer material, which has alkali resistance and is used as a reinforcing material to improve the crack resistance and impact resistance of the composite outer template.

[0021] A steel wire mesh 4 is installed inside the insulation mortar 2 located on the other side of the vacuum insulation panel 1. Both the fiberglass mesh 3 and the steel wire mesh 4 are arranged parallel to the surface of the vacuum insulation panel 1. The steel wire mesh 4 is a galvanized mesh made of longitudinal and transverse steel wires arranged at certain intervals and perpendicular to each other, welded together at the intersections. The performance indicators of the steel wire mesh 4 are shown in the table below.
