Precast concrete sandwich cladding wall panel provided with ribs

Abstract

The invention discloses a precast concrete sandwich cladding wall panel provided with ribs. The precast concrete sandwich cladding wall panel sequentially comprises an inner vane board, a thermal insulation layer and an outer vane board from inside to outside, wherein the thermal insulation layer is arranged between the inner vane board and the outer vane board, and the inner vane board, the thermal insulation layer and the outer vane board are integrally connected through pulling parts; the inner vane board comprises a flange plate and the ribs arranged on the flange plate, and the ribs are arranged on one side, facing the outer vane board, of the inner vane board. In the embodiment, the inner vane board is designed to be in a ribbed form, by comparison with common precast concrete sandwich cladding wall panels with inner vane boards being rectangular sections, the rigidity, the strength, the thermal insulation efficiency, the durability performance and the fireproof performance of the wallboard are guaranteed, the thickness of the wall panel is reduced, the effective use space of a building is increased, the use amount of concrete is reduced, the self-weight of the wall panel is reduced, the safety and the seismic performance of connected nodes are improved, and the precast concrete sandwich cladding wall panel is applicable to thermal insulation engineering of external walls of the building.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a ribbed prefabricated concrete sandwich wallboard. Background technique [0002] my country is a big energy-consuming country, and building energy consumption accounts for about 30% of the total energy consumption. The building envelope not only accounts for a large proportion of building energy consumption, but also directly affects the thermal insulation performance of the building structure. [0003] Since 1986, the country has continuously put forward high standards and high requirements for the thermal insulation performance of building structures, and has also continued to develop and innovate in building thermal insulation walls. Among the thermal insulation walls currently used in the market, the more advanced technology is undoubtedly the sandwich wall panels. [0004] The sandwich external wall panel is a new type of sandwich thermal insulation wall, which connects the inner...

Problems solved by technology

However, in order to obtain sufficient rigidity and strength, the current general-purpose sandwich external wall panels usually design the inner leaf panels thicker, which not only reduces the effective use of space for the building, but also causes the wall panels to be too heavy due to the excessive amount of concrete.

These will pose a great challenge to the safety of the joints connecting the sandwich external wall panels, and there will be certain safety hazards. At the same time, it will also have an extremely adverse impact on the seismic resistance of the structure
