Background technique

The prefabricated inner frame lightweight partition wall is a new type of partition wall that meets the requirements of building industrialization. It is made of two lightweight concrete panels connected by inserting bars to form a whole, and the sound insulation and moisture-proof lightweight materials are filled between the concrete panels, and the inner frame is set according to the requirements of force, fire prevention and embedded pipelines. The material of the inner frame can be concrete, steel or aluminum alloy. The prefabricated inner frame lightweight partition wall has light weight, good sound insulation and moisture resistance, no seams, and the wall is fully prefabricated in the factory. In addition, because the partition wall has an internal frame, the overall performance of the wall is good, and both in-plane and out-of-plane rigidity are relatively large. Therefore, when the partition wall is hoisted or subjected to accidental loads outside the plane, the wall is not easy to crack and has a good bearing capacity. Due to the above advantages, the inner frame lightweight partition wall has good application and market prospects in the field of prefabricated buildings.

The prefabricated inner frame lightweight partition wall can be used in steel frame and concrete frame. However, when this partition wall is installed at present, it is often to regroove the concrete beam or the floor slab after pouring, and then bury the partition wall connector.

In order to make the inner frame lightweight partition wall be installed accurately and quickly at the construction site, the installation nodes of the partition wall should be reasonably designed. Reasonable installation nodes can greatly improve work efficiency and save costs, and are the key technology of prefabricated partition walls.
