Composite partition board

Abstract

The invention discloses a composite partition wall board, which comprises a wall board body, wherein sound isolation grooves are formed in positions near two side surfaces of the wall board body; the sound isolation grooves and the wall board body are integrally connected through cement casting; a polyurethane heat insulation composite board is arranged in a position, near the upper surface and positioned between the two sound isolation grooves, of the wall board body; the polyurethane heat insulation composite board is fixedly arranged between the two sound isolation grooves; a sponge body is filled in the polyurethane heat insulation composite board; the lower surface of the polyurethane heat insulation composite board is provided with a hollow fiber concrete board; the hollow fiber concrete board and the polyurethane heat insulation composite board are connected in a sealed way; and the lower surface of the hollow fiber concrete board is provided with a concrete fiber board. The composite partition wall board has the advantages that a cold bridge phenomenon generated by a building body can be effectively prevented; good sound isolation performance is realized; board bodies are tightly connected, and the falling phenomenon cannot easily occur; a certain vibration reduction efficacy is realized; the damage to the wall board due to too great vibration amplitude is avoided; the durability is high; the fire-resistant grade is high; the environment is protected; the energy is saved; and the requirements of the modern building industrialization are met.

Description

technical field [0001] The invention relates to a partition wall board, in particular to a composite partition wall board. Background technique [0002] Since China's accession to the WTO, the economy has developed rapidly, science and technology are improving new achievements, and new products are constantly improving. Building materials are one of the remarkable signs of the country's development and progress. In some cold regions, the requirements for building insulation performance and energy saving are very high. The composite thermal insulation sandwich wallboard is developed on the basis of the board, which has the advantages of light weight, high strength, heat insulation, sound insulation, fire prevention, earthquake resistance and easy assembly, which makes this kind of wallboard highly valued. However, with the development of economy and technology, most of the existing buildings adopt frame structure, and the interior is divided into different spaces by lightweig...

Problems solved by technology

However, with the development of economy and technology, most of the existing buildings adopt frame structure, and the interior is divided into different spaces by lightweight inner partition boards. There are many types of existing inner partition boards, but they all have their own structural deficiencies. Or the problem of poor sound insulation, but also the problem of insufficient shock absorption performance, which affects its performance
