Assembled bidirectional composite wallboard and construction method thereof

Abstract

The invention discloses an assembled bidirectional composite wallboard. The assembled bidirectional composite wallboard comprises an inner wallboard and an outer wallboard, and is characterized in that the inner wallboard mainly consists of a concrete frame and autoclaved aerated concrete blocks filling the concrete frame; the outer wallboard mainly consists of a concrete protection layer on the outer side and an XPS insulation board on the inner side; the inner wallboard and the outer wallboard are assembled through thermomass MS / MC connecting pieces. The invention also provides a construction method of the assembled bidirectional composite wallboard. The wallboard is green, environmentally-friendly and low in resistance to shock, the component cost and construction cost can be further reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building technology, and relates to an assembled composite wall panel integrating heat preservation and load bearing, in particular to an assembled bidirectional composite wall panel and a construction method thereof. Background technique [0002] A large number of rivers, lakes and urban sewers have accumulated a lot of sludge over time. The ceramsite made by dredging, natural drying, raw material into balls, preheating, roasting and cooling of these sludges is called sludge ceramsite. Using sludge instead of clay to make sludge ceramsite concrete will not only reduce the building materials manufacturing industry and agricultural land contention, but also avoid secondary pollution of sludge, realize waste resource utilization and comprehensive utilization, and implement my country's development of circular economy and energy conservation. Emission reduction policy has good social and economic benefits and technica...

Problems solved by technology

[0004] At present, most prefabricated wall panels are made of concrete products. Not only is the structure heavy, it is not convenient for transportation and hoisting, but also a large amount of concrete is used, which requires a large amount of excavation of sand and gravel resources, pollutes the environment, and does not really achieve green environmental protection of prefabricated buildings. Require

[0005] At the same time, some existing composite walls cannot achieve the integration of heat preservation and load bearing

In addition, the concrete compactness of the post-cast connecting columns between the wall panels is not good, and the side connections of the wall panels are not tight, which affects the overall stability and earthquake resistance
