Description

A composite wall thermal insulation system

technical field

The utility model relates to the technical field of building energy saving, in particular to a composite wall thermal insulation system.

Background technique

In today's increasingly tense energy environment, the development and construction of energy-saving buildings is a trend, among which energy-saving treatment of walls, especially the external wall insulation system of building walls, is a popular development direction.

Polystyrene board or extruded board is a kind of thermal insulation building material with excellent performance. It contains 3 to 6 million independent closed air cells per cubic meter, and the volume of air contained is more than 98%. Due to the small thermal conductivity of air, And it is enclosed in foam plastic and cannot convect, so EPS (XPS) board is a kind of building material with excellent thermal insulation performance.

Polystyrene boards or extruded boards are generally made in factories and assembled on site. The specifications of polystyrene boards are mostly 1200×600cm, and cracks are prone to occur at the joints, which will affect the overall performance of the insulation system.

Utility model content

The purpose of the utility model is to provide a composite wall thermal insulation system, which has better thermal insulation, waterproof, fireproof and anti-crack properties, and has a longer service life.

The technical solution adopted by the utility model to solve the technical problem is: a composite wall thermal insulation system, which is attached to the wall of a building. , the second adhesive layer, the second leveling layer, the grid layer and the outer decorative surface.

A first leveling layer is also provided between the first adhesive layer and the wall.

The first leveling layer and the second leveling layer are formed by coating with a thermal insulation and fireproof slurry.

The thermal insulation and fireproof slurry is a slurry mixture formed by mixing vitrified microbeads, rubber powder, fiber, cement and water, wherein the vitrified microbeads can be made of closed-cell perlite and expanded vermiculite with similar functions , ceramsite or pumice instead, used for wall leveling, and also plays the role of heat preservation.

Both the first bonding layer and the second bonding layer are formed by coating the interface mortar or cement with fire prevention and bonding functions.

The insulation board layers are polystyrene boards or extruded plastic boards, and the gaps between adjacent polystyrene boards are filled with thermal insulation and fireproof slurry.

The grid layer is hot-dip galvanized welded mesh or alkali-resistant glass fiber grid cloth, which is used to improve the impact resistance of the outer wall and prevent the outer wall from cracking.

The exterior decorative surface is a paint layer or a brick veneer.

An anchor bolt with barbs is installed in the grid layer and the wall.

The beneficial effect of the utility model is that the structure of the heat preservation system is more optimized, and it has the prominent feature of integration of heat preservation, waterproof and fire prevention. It solves the problem that the external wall insulation system is prone to cracks. There is no cavity inside, which reduces the damage of wind pressure to the insulation layer. The structure is firm and the service life is longer.

Detailed ways

Embodiment one

As shown in Figure 1, a wall composite thermal insulation system is attached to the wall of a building. From the wall to the outside, it is the first leveling layer 1, the first adhesive layer 2, the insulation board layer 3, and the second adhesive layer. The connecting layer 4, the second leveling layer 5, the grid layer 6 and the outer decorative surface 7, the outer decorative surface is paint.

The first leveling layer 1 and the second leveling layer 5 are coatings formed by coating a thermal insulation and fireproof slurry. Thermal insulation and fireproof slurry is a kind of slurry formed by mixing vitrified microbeads, rubber powder, fiber, cement and water. The vitrified microbeads can be made of closed-cell perlite, expanded vermiculite, ceramic stone and Instead of pumice, it is used for leveling the wall and also plays a certain role in heat preservation.

Both the first bonding layer 2 and the second bonding layer 4 are coating layers formed by coating interface mortar with fireproofing and bonding functions. The interface mortar is made by mixing the interface agent prepared by polymer emulsion and additives with cement and medium sand in a certain proportion, and is used to improve the bonding performance of the base layer or the surface of the insulation layer.

The insulation board layer 3 is a polystyrene board or an extruded board, and the specification is 1200 * 600cm, which is available in the market. Insulation and fireproof slurry is pressed into the gap between adjacent polystyrene boards.

The mesh layer 6 is an alkali-resistant glass fiber mesh cloth, which is used to improve the impact resistance of the outer wall and prevent the outer wall from cracking.

The specific construction methods are:

1) Clean and level the wall;

2) Hang the vertical line, set the square, and play the control line;

3) Bond the EPS board (or XPS board), apply 15-20mm thick vitrified microbeads to bond the leveling material and paste the EPS board (or XPS board) at the wrong seam, press the EPS board (or XPS board) evenly and lightly when bonding, Embed the EPS board (or XPS board) into the vitrified bead adhesive leveling material, and check the flatness and verticality at any time. Leave a 10mm gap between the EPS boards (or XPS boards) and fill them with vitrified microbead leveling materials;

4) leveling construction;

5) Finishing layer construction.

Embodiment two

As shown in Figure 2, the difference from Embodiment 1 is:

A plastic anchor bolt 8 is installed in the grid layer 6 and the wall body 9 to increase the tensile strength and shear strength and prevent the insulation layer from falling off.

Grid layer 6 is post-hot-dip galvanized welded wire mesh.

The exterior decoration surface 7 is facing brick.

Embodiment three

As shown in Figure 3, the difference from Example 1 is that the polystyrene board or extruded board in the insulation board layer 3 is directly bonded to the wall through an adhesive, which can also play a good role in bonding and heat preservation. Effect.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
