Description

Beads used for lamination of vacuum insulation panels for construction

technical field

The utility model relates to an accessory used for installing a building insulation layer, in particular to a bead used for pressing a building vacuum insulation board.

Background technique

Vacuum insulation is an upgraded product of traditional insulation. It is a new, energy-saving, efficient and environmentally friendly insulation material. The vacuum insulation board is composed of a high-barrier vacuum film on the surface as a vacuum chamber, an inorganic microporous core material inside, and a water vapor adsorbent. The vacuum degree of the vacuum chamber is increased by high vacuum, and the gas remaining in the microporous core material in the high-barrier vacuum chamber is removed, so that the heat transfer path through the gas is eliminated, and the heat conduction is isolated. The thermal conductivity after vacuum is higher than that before vacuum. It can be reduced by 8 times, achieving the purpose of high-efficiency thermal insulation and energy saving. In the production process of vacuum insulation boards, ODS substances are not used. The ultra-low thermal conductivity makes the thickness of the insulation boards thinner, and the unit material consumption is low. It has the dual advantages of environmental protection and energy saving. In recent years, vacuum insulation technology has entered the building insulation market and has been recognized by the market for its high efficiency and environmental protection performance. However, as a new type of insulation material, it needs more improvement in practical applications. The current vacuum insulation panel system is in The structure of the exterior wall of the building is to use polymer mortar to directly paste the insulation board on the wall. After filling the joints, apply a layer of polymer mortar, lay grid cloth, and level the surface with the second layer. The structure of this insulation system has the following limitations to varying degrees:

1. Due to the water vapor impermeability of the vacuum insulation board, a large amount of water remains when the board is pasted, and the water vapor in the joint surface of the insulation board and the wall cannot be released for a long time. The drying time is very long, so that the inside of the board is in a humid state for a long time, and the polymer mortar inside The adhesive force of the glue component decays quickly in moisture.

2. The high barrier film of the vacuum insulation panel is composed of polymer materials. In order to improve the adhesion between the insulation board and the wall, the outermost layer of the vacuum barrier film is compounded with a layer of glass fiber cloth. High-quality polymer mortar contains high alkalinity. Long-term contact of glass fiber cloth with alkali will corrode the glass fiber, making the glass fiber hard and brittle, which will affect the safety of the entire insulation system.

3. The vacuum insulation board cannot be cut or punctured, and its life is guaranteed by maintaining the vacuum inside the board. In order to improve the adhesion, anchors are needed to assist in fixing the insulation board for added security. Although a variety of methods have been proposed based on the current technology to arrange reserved anchor holes, these methods cannot fundamentally solve the anchoring problem between the vacuum insulation board and the body of wall.

Contents of the invention

In order to make up for the above deficiencies, the utility model provides a bead used for lamination of vacuum insulation panels for construction. The bead used for lamination of vacuum insulation panels for buildings can realize fast and stable anchoring and installation of vacuum insulation panels, which is conducive to improving project quality. , saving resources.

The technical scheme adopted by the utility model in order to solve the technical problem is: a layering strip used for pressing the vacuum insulation board for building, including a flat fixing plate and an L-shaped pressing plate, and the fixing plate is provided with several Anchor holes arranged in the length direction, at least one side wall in the width direction of the fixing plate is fixed with an L-shaped pressing plate, the opening direction of the pressing plate faces the side away from the fixing plate, when one side of the fixing plate is provided with When pressing the plate, the bead is a single-sided bayonet bead, which is used for single-sided connection of the inner corner. When there are pressure plates on both sides of the fixed plate, the bead is a double-sided bayonet bead, which is used for double-sided connection. The depth of the bayonet is 1-3 cm, the bead is made of engineering plastic or modified PVC, and the length is 800-3000 cm, which can be cut or docked according to the actual needs of the wall. This material has the characteristics of thermal conductivity and good durability.

As a further improvement of the utility model, the anchor holes of the bead are at least one of round holes and long holes arranged at intervals, the diameter of the round holes is 0.5-1 cm, and the width of the long holes is 0.5-1 cm , the interval of each round hole is 20-50 cm.

The beneficial technical effects of the utility model are: the utility model can be firmly fixed on the wall, and the notch of the bead is used to fix the insulation board, and multiple anchor points are simultaneously loaded by the board, which effectively solves the problem of anchoring the vacuum insulation board. The safety problem of frequent falling off; the utility model stabilizes the vacuum insulation board on the wall without waiting for the polymer mortar pasted on the insulation board to solidify, which can shorten the construction period; reduces the amount of polymer mortar used, and reduces the alkaline corrosion of the mortar on the insulation board The outer layer of glass fiber cloth and composite adhesive layer improves the service life of the insulation board; reduces the building load and also reduces the thickness of the insulation layer, so that the board has no internal expansion force, increases the strength of the board, and improves the building quality. The anti-seismic performance improves the project quality and saves resources; there is a gap between the vacuum insulation board and the wall, which improves the internal air circulation performance, reduces the generation of condensed water at the hot and cold bridges, and prevents condensation; The utility model has the advantages of simple structure, low cost and convenient use.
