Description

Fasteners for exterior wall insulation

(1) Technical field

The invention relates to a heat-insulating and sound-insulating component and a fixing piece for the outer wall of a building, more specifically a fixing piece for fixing a heat-insulating material layer in the outer wall insulation layer of a building.

(2) Background technology

According to the measured data, about one-third of the heat of heating residential buildings in northern my country is transmitted to the outside through the outer wall, another third of the heat is transmitted to the outside through the windows, and one third of the heat is transmitted through the window cracks. It can be seen that the heat transmitted from the outer wall accounts for a considerable share. In order to improve the indoor thermal environment capacity and save heating energy consumption, it is undoubtedly very important to improve the thermal insulation performance of the wall. Compared with developed countries, the thermal insulation performance of residential exterior walls in heating areas in my country is very poor, which is about 2-5 times lower. Can only meet the requirements of the lower limit thermal resistance. my country has also developed clay hollow bricks, concrete thermal insulation composite panels, lightweight thermal insulation panels and various composite thermal insulation walls to improve the thermal insulation performance of external walls.

In 1986, the competent department of my country's construction promulgated the "Energy Conservation Standard for Civil Buildings". Greatly improve the insulation performance of the wall.”

Rock wool is an excellent and efficient thermal insulation material. The rock wool board made of rock wool products has good thermal insulation, sound insulation and sound absorption properties. Compared with existing thermal insulation materials, rock wool products have light bulk density and thermal conductivity. Small, non-combustible, fireproof and non-toxic, wide range of applicable temperature, stable chemical properties, long service life and other outstanding advantages.

However, how to fix the rock wool product rock wool board on the outer wall has become a technical problem that must be solved. For this reason, someone has developed a plastic wall insulation layer fixing piece. This fixing piece is composed of a The plastic disc is composed of a plastic rod perpendicular to the disc surface and a plastic disc with a hole in the center of the plastic disc surface. The plastic disc with hole in the center is inserted into the above-mentioned plastic rod perpendicular to the disc face through its central circular hole. Sandwich the thermal insulation material rock wool board between two plastic discs, and then use the adhesive to bond the plastic discs to the outer wall. Because the insulation layer is on the outer wall, the temperature difference between day and night in the external environment is large, and it is also affected by climate factors. The plastic is easy to age and cracks; The body connection is not firm, causing the insulation material rock wool board to crack or fall off. ZL91203565.X announces a fixed connector for rock wool external thermal insulation composite walls. When this product is in use, rock wool is not easy to insert into its tie rods.
