Description

Thermal insulation board for building structure

technical field

The invention relates to a thermal insulation and sound insulation board for building structures, which is mainly (but not exclusively) used for wall panels (including load-bearing walls and non-load-bearing partition walls) and building and roof panels in building structures.

Background technique

At present, my country vigorously advocates green buildings and energy-saving buildings. Traditional buildings use a large number of traditional building materials such as steel bars, cement, and clay bricks, which consume a lot of ore resources and fertile land. The production process also consumes a lot of energy and emits a lot. carbon dioxide, causing damage to the ecological environment.

Traditional wall insulation methods usually use materials such as hollow bricks, porous bricks, hollow blocks, and aerated blocks, and paste or hang a layer of special insulation materials on the enclosure structure. This method usually has the disadvantages of thick walls, complicated procedures, low construction efficiency, and poor comprehensive performance. However, modern buildings have higher requirements on the structure's earthquake resistance, fire prevention, sound insulation performance, comfort, and environmental protection, which requires the search for new alternative materials.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide an energy-saving, heat-preserving, environmentally friendly, non-toxic, light and high-strength, fire-proof and moisture-proof, sound-absorbing and sound-insulating, earthquake-resistant and wind-resistant, convenient construction, durable, and industrialized modular production. The building structure uses thermal insulation and sound insulation panels.

The technical solution of the present invention is: a heat insulation and sound insulation board for building structure, including a panel and a core material, a reinforcement layer is arranged between the panel and the core material, the reinforcement layer is made of high-strength plant fiber fabric material, and all relative Adjacent layers are bonded together by resin glue to form a sandwich panel structure.

In the whole panel, the panel is the main load-bearing skeleton, while the core material mainly plays the role of energy saving, heat preservation, fire prevention and supporting the panel, and the reinforcement layer has the advantages of improving sound insulation capacity and bearing capacity, and reducing product thickness. More than 80% of the heat insulation and sound insulation panels for the entire structure can be reused, 100% can be used as fuel, and it does not contain toxins, carcinogens, and toxic gases.

The thermal insulation and sound insulation panels for building structures can be used not only for load-bearing walls, but also for non-load-bearing walls, and can also be used for buildings and roof panels.

The heat insulation and sound insulation panels for building structures can bear load alone, or can be combined with beams or columns for other arbitrary structures to bear load together.

The thermal insulation and sound insulation panels for building structures can be prepared by cold pressing or hot pressing.

The core material should be expanded polystyrene board (Expanded Polystyrene, referred to as EPS), and foam materials such as extruded polystyrene board (Extruded Polystyrene, referred to as XPS).

The panel is preferably oriented strand board (Oriented Strand Board, OSB for short) or plywood (Plywood), and its raw material can be fast-growing tree species, which greatly improves the utilization rate and added value of fast-growing tree species.

The panels can be subjected to special treatments such as anti-corrosion and insect-proof as required.

The reinforcing layer is preferably a high-strength plant fiber fabric, and chopped fiber mat or fiber-reinforced composite material can also be used.

The core material can be reserved or post-processed according to needs, and the holes are mainly used for the passage of facilities such as water and electricity pipelines in the walls of building structures or buildings and roof panels.

When the thermal insulation and sound insulation board for building structure is used as a wall panel, a moisture-proof layer and a finish layer can be provided on its inner surface, and a waterproof layer and an outer finish can be provided on its outer surface as required.

When the thermal insulation board for building structure is used for building and roof panels, a moisture-proof layer and a finishing layer can be provided on its lower surface, and a waterproof layer and a finishing layer can be provided on its upper surface as required.

The size of the heat insulation and sound insulation boards for building structures can be designed modularly according to the building structure, and adjacent boards can be connected by any long strip or I-shaped rods, bolts or nails; and in all splicing The parts are applied with sealant and other materials.

The present invention meets the needs of national green building and energy saving and emission reduction, combined with materials such as oriented strand board (OSB), structural plywood (Plywood) and foamed plastics, its main application is: 1) It can be used as walls such as clay bricks, hollow bricks and blocks substitute products. Traditional walls consume a lot of natural resources and energy and cause great damage to the environment, while the materials used in thermal insulation and sound insulation panels for structures have many advantages such as renewable and reusable, and can be promoted and utilized as wall materials. 2) Used as floor and roof panels, its mechanical properties are similar to I-beams, the upper and lower panels are used as flanges, and the core material is used as webs, so it has the characteristics of heat preservation, energy saving, light weight and high strength. 3) Due to its excellent comprehensive performance, thermal insulation and sound insulation panels for structures can also be used in temporary buildings, emergency relief and post-disaster reconstruction.

The beneficial effects of the invention are: energy saving and heat preservation, environmental protection and non-toxicity, light weight and high strength, fire prevention and moisture resistance, sound absorption and sound insulation, earthquake resistance and wind resistance, convenient construction, durability, and industrialized modular production; it can be used for building structure walls, It can also be used in buildings, roof panels, etc., and can also be used in temporary construction, emergency relief and post-disaster reconstruction and other fields.
