Description

A kind of light concrete grouting method and the wall formed by it

Technical field

The present invention relates to the technical field of building walls, and specifically to a light concrete grouting method and the wall formed therefrom.

Background technique

Light concrete refers to concrete with an apparent density not greater than 1950kg/ ^m3 , including foam concrete, polystyrene particle concrete and other lightweight aggregate concrete. Light concrete is often poured into the formwork through grouting to form a wall. The main production process of light concrete walls in the existing technology is to use light steel keels as supports, and use steel mesh, wooden formwork, fiber cement boards, etc. fixed on the keels to form a formwork, and the formwork is filled with light concrete. The existing technology of light concrete walls has various forms, covering building exterior walls and interior walls, including light steel light concrete shear walls (JGJ 383-2016), foam concrete light steel keel composite walls (CECS 406: 2015), Lightweight concrete enclosure wall panels (T/CECS 1170-2022), lightweight thermal insulation structural integrated wall panels (T/CECS 1201-2022), light steel frame light concrete partition walls (CECS 452-2016), etc.

During the grouting process of light concrete, due to the weight of the concrete, the formwork will be extruded and deformed by the concrete, eventually causing expansion defects. In this regard, existing technical solutions mainly include: (1) strengthening the connection relationship between formwork or between formwork and frame; (2) strengthening the external support of formwork; (3) pouring in layers and waiting for the lower concrete to reach a certain strength The upper layer of concrete is then grouted.

In addition, since the formwork of light concrete walls in the existing technology usually uses screws (bolts) to connect to the keel, the screws (bolts) will penetrate the formwork, so the decorative surface cannot be prefabricated on the surface of the formwork, and the formwork needs to be removed after the light concrete is poured. Decorative surface construction can only be carried out after leveling. Therefore, a large number of existing exterior decorative board categories on the market cannot be directly used in the construction of light concrete walls, which greatly limits the promotion and development of light concrete walls.
