Structure and production method of sound insulation board frame combined with floor board

Abstract

The invention discloses a structure and a production method of a sound-insulating board frame combined with a floor board. The floor panel structure includes steel frames and concrete layers filled between the steel frames. The concrete layer successively includes a decorative layer with a thickness of 5-15mm, a fine stone concrete layer with a thickness of 30-50mm, a foamed cement layer with a thickness of 100-140mm, a foamed ceramic material layer with a thickness of 5-15mm and a thickness of 6‑20mm cement mortar protective layer; among them, a sound insulation layer with a thickness of 40‑50mm is set inside the foamed cement layer. The sound insulation layer includes two building boards and a polymer damping material located between the two building boards. The sound insulation board frame combined with a floor panel structure of the present invention significantly improves the sound insulation, and at the same time, the optimized steel frame greatly improves the load-bearing capacity, so that it can be directly assembled as an assembly component of a large building without prefabricating a load-bearing frame.

Description

technical field [0001] The invention relates to a building wall board structure, in particular to a sound-insulating board frame combined with a floor board structure and a production process. Background technique [0002] With the development of modern industrial technology, housing construction technology has also been improved. Due to the fast construction speed and low production cost, prefabricated buildings have been rapidly promoted all over the world. Prefabricated buildings refer to buildings assembled from prefabricated parts on site. However, the structural strength between the existing prefabricated floor panels and wall panels is not as good as that of cast-in-place columns, beams, floors and roof layers, and cannot meet the requirements for assembling large buildings. [0003] In addition, the requirements for the sound insulation performance of prefabricated buildings are also increasing. At present, the common building sound insulation materials on the marke...

Problems solved by technology

However, the structural strength between the existing prefabricated floor panels and wall panels is not as good as that of cast-in-place columns, beams, floors and roof layers, and cannot meet the requirements of assembling large buildings

[0003] In addition, the requirements for the sound insulation performance of prefabricated buildings are also increasing. At present, the common building sound insulation materials on the market include organic materials such as phenolic resin and polyvinyl chloride resin. Although these materials have a certain sound insulation effect, due to their heat resistance Poor performance, flammable at high temperature, and easy to decompose to produce toxic gases and other defects are gradually eliminated by the market
