Composite heat-preserving wallboard

Abstract

The invention discloses a composite heat-preserving wallboard which is composed of panels, rib plates, a core material and reinforcing materials. The panels comprise an upper panel and a lower panel. The rib plates comprise an outside rib plate A and an outside rib plate B. The panels and the rib plates form a cross section in a closed geometry form. The core material is placed into the cross section. The reinforcing materials are placed in the panels and the rib plates. The panels and the rib plates are made of concrete. A heat preserving core material is adopted as the core material. Meshed prestress long-fiber reinforcing grids are adopted as the reinforcing materials and compounded with the panels and the rib plates made of the concrete. According to the composite heat-preserving wallboard, as the meshed prestress long-fiber reinforcing grids are compounded, on the premise of hardly increasing the mass additionally, the panels and the rib plates are reinforced, it is ensured that the rib plates are effectively connected with the panels at the two sides, the fracture surface in the closed geometry form is formed, and crack resistance and ultimate bearing capacity of the composite heat-preserving wallboard are greatly improved.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a composite thermal insulation wallboard capable of avoiding the use of steel bars, fully reusing solid waste, effectively realizing energy saving and heat preservation, and having a higher bearing capacity. Background technique [0002] In building energy consumption, the energy consumption caused by external walls accounts for about 50% of the total energy consumption of buildings. The development of efficient new thermal insulation walls is the key to realizing building energy conservation. [0003] The emergence of various new wall materials has a history of decades, and the application scope and consumption are increasing year by year. Its development direction is no longer just to replace traditional red bricks. However, many wall materials including hollow bricks, hollow blocks, and lightweight aggregate concrete have a certain load-bearing capacity, but it is often difficu...
