Internal thermal insulation house of integral spray finishing costalia concrete structure and construction method thereof

Abstract

The invention provides an internal insulation house having integral spray painting rib concrete structure. The house is characterized in that the internal insulation house is assembled by a prefabricated insulation interior wall, a roof slab, a floor formwork, and an internal partition wall board, the heat insulation outer layer is formed by directly spray paining the concrete structure layer, and the wall, pole, beam, flow, and roof slab before directly spray painting the concrete are all permanent walls and need not to be dismounted. A reverse construction method is formed which firstly constructs the house internal decoration layer, the heat insulation layer, and fills the walls, and then constructs the main bearing components. The invention can save great amount of formworks, greatly short the construction period, reduce the engineering cost, has excellent aseismic effect, can also effectively solve the crack problem of the slurry protection layer outside the heat insulation layer, and is especially suitable for the building construction of single floor or multiple floor house.

Description

technical field [0001] The invention relates to an inner thermal insulation house with an integral spray-coated rib plate concrete structure and a construction method, belonging to the technical field of building structures and construction methods. Background technique [0002] In the construction of houses, the traditional construction method is to construct the main structure first, and then install the insulation layer and the interior surface wall or both at the same time. When pouring the concrete load-bearing wall, a large number of formwork supports are required. In order to make the reinforced concrete wall reach To meet energy-saving requirements, people use reinforced grid sandwich panels as load-bearing walls with concrete sandwich insulation. Its method is also the same as that of ordinary concrete wall construction, supporting the formwork on both sides, relying on a large amount of wood, steel pipes on both sides and through the through bolts passing through t...

Problems solved by technology

Its method is also the same as that of ordinary concrete wall construction, supporting the formwork on both sides, relying on a large amount of wood, steel pipes on both sides and through the through bolts passing through the wall to fix the formwork, thus wasting a lot of wood, steel and labor, and some will use one side or The steel wire grid sandwich panel with steel wire mesh on both sides is placed in the outer formwork of the wall, and then the concrete for the wall is poured. After the formwork is removed, the crack-proof mortar is applied on the outer side of the outer steel wire grid sandwich panel. The construction industry is commonly known as the "large mold built-in" method. When the concrete is poured on the inner wall, the lateral stress of the concrete will squeeze the insulation board to the outer steel wire mesh, so that the steel wire mesh directly contacts the insulation layer, causing the post-plastering surface layer to be damaged. When using mortar, the surface layer mortar cannot wrap the steel mesh well, thus causing the surface layer to crack
