Preparation method of lightweight self-insulating composite wallboard

Abstract

The invention belongs to the technical field of architectural engineering and particularly relates to a light self-insulation composite wallboard for architectural engineering such as frames, framed bents and shear walls and a manufacturing method thereof. The light self-insulation composite wallboard comprises an insulation board, ceramsite concrete sheets are arranged on both sides of the insulation board, and the ceramsite concrete sheets on the two sides are fixedly connected with each other through a shear-resisting and compression-resisting connecting part which penetrates through the insulation board. Steel wire meshes are arranged in the ceramsite concrete sheets, the left end and the upper end of the insulation board are concave inside the ceramsite concrete sheets on the two sides so as to form a groove, and the right end and the lower end of the insulation board protrude out of the ceramsite concrete sheets on the two sides so as to form a rib. A wall body is carried to a construction site after being prefabricated in a factory, hoisting installation is adopted on the construction site, components are assembled into a whole in a reliable connection mode, and therefore housing industrialization is facilitated. Construction of an insulation layer is not needed after a building main structure is completed, so that the construction procedure is simplified, the construction progress is accelerated, and construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and specifically relates to a preparation method of a lightweight self-insulating composite wallboard used in construction projects such as frames, bent frames, and shear walls. Background technique [0002] The current thermal insulation wall panels are usually installed by pasting the thermal insulation material directly on the outside of the wall, and the thermal insulation materials of the outer wall are mostly made of EPS board, XPS board and other materials, which are all lipid materials. , low ignition point, can not play a role in fire prevention; due to the problem of weak paste, the panel is prone to fall during use. [0003] The on-site construction of the wall not only causes waste of materials and environmental pollution, but also has poor thermal insulation performance and short durability of the thermal insulation layer. In addition, with the development of social...

Problems solved by technology

However, when this kind of wallboard is used, ordinary concrete is used. Because of its heavy weight, the process of hoisting, transportation and installation of the wallboard will generate extrusion normal stress and shear stress on the organic insulation layer in the middle, resulting in extreme damage to the wall. Cracks are easy to occur, and in severe cases, the outer layer of the wall will fall off, thereby limiting the application of this composite wallboard. How to reduce the normal stress on the insulation layer and the shear stress on the contact surface with the concrete, and strengthen the gap between the insulation board and the concrete. Excellent adhesion and shear resistance will be the key to the application of composite sandwich wall panels
