Description

Fireproof composite exterior wall insulation board

technical field

The utility model relates to a novel external wall thermal insulation device, in particular to a fireproof composite external wall thermal insulation board, which belongs to the technical field of building energy conservation.

Background technique

In recent years, building external insulation materials are generally flammable materials, which have become a new type of fire hazard, and have caused many fires, resulting in serious casualties and property losses. Therefore, in 2011, the state explicitly stipulated that civil building external insulation materials be included in the scope of fire protection design review, fire protection acceptance and filing spot checks of construction projects, requiring building external insulation materials to use insulation materials with a combustion performance of Class A. However, inorganic thermal insulation materials such as foamed ceramic boards and foamed cement boards have the disadvantages of large thermal conductivity, high brittleness, fragility, poor impact resistance, and high water absorption. There are quality risks when used as external wall insulation materials, while glass wool Although , rock wool, etc. have the advantages of small thermal conductivity and high fire resistance, their strength is low and cannot meet the requirements of building external insulation. In addition, fiber dust is highly toxic to the human body and is not convenient to use. Therefore, inorganic insulation boards are used for building external insulation. field can not be popularized and used on a large scale.

Utility model content

The purpose of this utility model is to propose a fireproof composite exterior wall insulation board with high flatness and good impact resistance in view of the problems in the above-mentioned prior art.

In order to achieve the above purpose, the improvement of the fireproof composite exterior wall insulation board of the present invention is that it includes a panel, a bottom plate and an insulation layer arranged between the panel and the bottom plate, and the panel and the bottom plate are all inorganic materials. The panel has counterbore holes for anchor bolts.

A further improvement of the utility model is that the panel is a calcium silicate board or a cement pressure board.

A further improvement of the utility model is that the bottom plate is a calcium silicate board or a cement pressure plate, and the bottom plate is a perforated plate.

A further improvement of the utility model is that the thermal insulation layer is a rock wool board or a glass wool board, and reinforcing ribs are provided in the middle of the thermal insulation layer.

The further improvement of the utility model is that the board seams between the two adjacent fireproof composite exterior wall insulation boards are filled with foamed polyurethane, and the board seams are sealed with weather-resistant silicone glue.

The utility model has the advantages that: the fireproof composite external wall insulation board of the utility model has simple structure and reasonable design, adopts a double-sided sandwich structure composed of a panel, an insulation layer and a bottom plate, and uses an inorganic plate with good physical properties to cover the insulation layer. Wrapped up to form a whole, it can effectively cover up the shortcomings of rock wool board, glass wool board and other insulation materials such as low mechanical strength and high water absorption; and fill the gap between the two insulation boards with foamed polyurethane and use The weather-resistant silicone glue seals the board seams, and there is no need to plaster the insulation board, making it easy and quick to install. In a word, the utility model has the advantages of good fire resistance, high impact resistance, good crack resistance and high flatness, and is especially suitable for coatings with high flatness requirements such as fluorocarbon paint and imitation stone paint for exterior walls.

Detailed ways

Embodiment one

The fireproof composite exterior wall insulation board of this embodiment has a structure as shown in Figure 1, including a panel 1, a bottom plate 4 and an insulation layer 3 arranged between the panel 1 and the bottom plate 4, which is a typical double-sided sandwich composite structure, The face plate 1 and the bottom plate 4 are both inorganic materials, wherein the face plate 1 and the bottom plate 4 can adopt calcium silicate board or cement pressure plate with low shrinkage, high impact resistance and small deformation. The cross-section of the hole 5 can be circular, regular hexagonal or other shapes, and the bottom plate 4 can be a perforated plate or a non-perforated plate. The insulation layer 3 is a rock wool board, glass wool board or other loose fiber inorganic insulation boards, and a reinforcement rib 2 is provided in the middle of the insulation layer 3. Insulation materials such as rock wool board or glass wool board, the reinforcing rib 2 is a material with a combustion performance such as rock wool tape or foamed ceramic board, which has a certain tensile strength. In addition, the reinforcing rib can be arranged horizontally, vertically or Cross arrangement. The gap between two adjacent fireproof composite external wall insulation boards is filled with foamed polyurethane and sealed with weather-resistant silicone glue, so there is no need to make crack-resistant mortar composite alkali-resistant glass fiber mesh cloth for plastering.

When making the insulation board, first reserve the anchor bolt sink hole 5 on the panel 1 according to the design requirements, and then place the rock wool tape (reinforcing rib) and the rock wool board (insulation layer) on the roller gluer and use fireproof polyurethane glue for double-sided Glue treatment, and finally spread it between the panel 1 and the bottom plate 4, and keep the press for 24 hours. When installing, first cut a whole piece of insulation board into a certain size according to the site requirements; then paste the cut insulation board on the surface of the outer wall through polymer bonding mortar, and use anchor bolts to further anchor and reinforce the insulation board , and the counterbore 5 reserved on the panel 1 facilitates the frontal anchoring of the anchor bolt; then fill the gap between the two insulation boards with foamed polyurethane, and use weather-resistant silicone glue to seal the gap between the boards; finally use a special flexible filling After the cement seals the counterbore of the anchor bolt and repairs it flat, the outer surface of the insulation board can be decorated, and the outer wall can be painted with fluorocarbon paint or imitation stone paint.

Except above-mentioned embodiment, the utility model also can have other embodiment. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the utility model.
