A kind of preparation method of thermal insulation wallboard of wooden structure building

Abstract

The invention discloses a thermal insulation wallboard of wooden structure building. The thermal insulation wallboard is composed of a panel and a core board, wherein the core board is composed of a moisture-proof heat insulation board placed in a wooden frame; the moisture-proof heat insulation board is composed of mats made of rice straws or wheat straws and a waterproof roll covering the two sides of the mats; wooden bars for shaping are arranged outside the waterproof roll. The preparation method comprises the following steps: drying rice straws or wheat straws until the moisture content is less than 15%, and then preparing into mats by a bundling machine; laying a waterproof roll on the upper and lower surfaces of the mats respectively to prepare a moisture-proof heat insulation board; symmetrically placing wooden bars for shaping on the upper and lower surfaces of the moisture-proof heat insulation board; preparing a wooden frame with square timber, wherein the internal dimension of the wooden frame is the same as that of the moisture-proof heat insulation board; placing the moisture-proof heat insulation board into the wooden frame, and laying panels up and down. The thermal insulation wallboard is low in cost, good in thermal insulation and moisture-proof effects, is environment-friendly and pollution-free, and is an effective way for making full use of rice straw or wheat straw wastes and solving the environmental pollution problem caused by burning.

Description

technical field [0001] The invention relates to a building structure, in particular to a thermal insulation wallboard of a wooden structure building and a preparation method thereof. Background technique [0002] Thermal insulation wall panels are one of the main components of wooden structures. At present, most construction companies in my country use wood or foamed plastics to make thermal insulation wall panels. In some foreign countries, such as Germany, some wooden buildings currently use wool as a filler for wooden wall panels for insulation. Japan has used rigid foam boards, foam insulation boards, glass fibers and other insulation materials in wooden structures. These thermal insulation materials have disadvantages in varying degrees. For example, although the thermal insulation wallboards made of foamed plastics, rigid foams, and glass fibers have better thermal insulation effects, they will cause certain pollution to the environment. Pollution is even worse. Ger...

Problems solved by technology

These thermal insulation materials have disadvantages in varying degrees. For example, although the thermal insulation wallboards made of foamed plastics, rigid foams, and glass fibers have better thermal insulation effects, they will cause certain pollution to the environment. more serious pollution

Germany uses wool as thermal insulation material for wooden structures, and the cost is too high, so it is not suitable for our country with a large population and an underdeveloped economy.

[0003] In addition, at present, a large amount of rice straw and wheat straw left in the fields after harvesting rice and wheat in rural areas of our country cannot be effectively used, and farmers have to burn them for planting in the next year, which causes serious air pollution. One of the main factors for the increasingly frequent occurrence of smog weather, causing great harm to human health

At the same time, the smoke formed by incineration reduces the visibility of the air, directly affecting the safe operation of civil aviation, railways, and expressways.
