Packaged-type composite performance building dismantling-free formwork

Abstract

The invention relates to a packaged-type composite performance building dismantling-free formwork and belongs to building materials and construction materials. The particularity of the formwork is that sandwich materials are sealed and packaged in a cement formwork shell made by a special mould. In a cast-in-place construction site, the formwork is subjected to assembling operation according to the configured sequence, the formwork is fixed on a formwork bracket, and after concrete pouring and tamping is completed, the formwork does not need to be dismantled. According to the packaged-type composite performance building dismantling-free formwork, the construction efficiency of a heat insulation outer wall and a heat insulation and sound insulation floor plate is improved, the safety and reliability of a heat insulation outer wall structure are strengthened, and important practical significance is achieved to meet the requirements of building energy saving and environmental protection, improve the building construction quality, change a traditional cast-in-place building formwork process, save timber resources and reduce the building and construction cost.

Description

technical field [0001] The invention relates to building materials and construction materials, in particular to formwork panel materials used for pouring and tamping of cast-in-place reinforced concrete structural members, which can be used for vertical structural members (shear walls, columns) and also for horizontal structures Components (beams, floors). Background technique [0002] At present, the construction process of conventional cast-in-place reinforced concrete buildings is actually a process of constantly repeating a set of processes. That is: preparing formwork, making steel bars, erecting brackets, assembling formwork, laying steel bars, pouring concrete, dismantling formwork, until the main body of the building structure is capped and completed, so a large number of formwork is required in the construction process. At present, the formwork is made of wood, plywood, steel plate, aluminum plate, etc. without exception, and the most used formwork is plywood. Ply...

Problems solved by technology

The current measures for the external thermal insulation structure of the external wall of the building generally include: the method of pasting the thermal insulation integrated board, the method of fixing the thermal insulation board (insulation mortar) with steel wire mesh, the method of wrapping aerated concrete blocks, and the method of dry-hanging the external wall board and filling the thermal insulation material, etc. However, the above-mentioned various external thermal insulation construction methods are all installed after the building structure is completed, which has disadvantages such as complex structure, long construction period, high cost, and increased building area of ​​the external wall. What is more serious is that the former two still have glue Safety hazards of failure and burning of insulation boards. In some areas, there have been accidents where the wall body has slipped and extruded polystyrene boards have caught fire, which has greatly affected the lives of the people.
