Problems solved by technology

At present, most of these external wall insulation technologies have problems such as uneven construction quality and difficult supervision, and even more serious accidents such as external wall insulation falling off and fires during construction
One of the important reasons for this is that the external thermal insulation technology of external walls is used for high-altitude operations, the construction conditions are poor, and the external thermal insulation layer of external walls is not firmly bonded to the main structure of the building, which leads to frequent accidents in the engineering quality of external thermal insulation of external walls , resulting in potential safety hazards in housing construction and increasing the maintenance cost of housing construction

Embodiment 1

[0037] The invention can be used as a formwork for cast-in-place floor slabs of multi-storey or high-rise buildings. The construction process is as follows: the reinforced truss gypsum board with insulation layer and the new formwork without dismantling (hereinafter referred to as: gypsum formwork) are transported to the site and stored → the formwork support frame is erected → the gypsum formwork is hoisted → the gypsum formwork is installed → the steel bar binding and Pipeline laying → side formwork installation → acceptance → concrete pouring. So far, adopt the present invention as the cast-in-place floor slab of multi-storey or high-rise building permanently without removing formwork, pour reinforced concrete on it, after cast-in-place concrete is hardened, the reinforced truss gypsum board with insulation layer does not dismantle, and it and cast-in-place The floor slabs bear the external load together, thus becoming a part of the building's floor slab and having the func...

Embodiment 2

[0039] The present invention can be used as the external wall template of the cast-in-place wall body of multi-storey or high-rise buildings. The construction process is as follows: A reinforced truss gypsum board with insulation layer and a new formwork without dismantling (hereinafter referred to as: gypsum formwork) are transported to the site and stored → hoisting of gypsum formwork → temporary support installation of gypsum formwork → wall reinforcement binding and pipelines Laying→formwork installation on the other side of the wall→acceptance→wall concrete pouring. So far, adopt the present invention as the permanent dismantling-free formwork of the cast-in-place wall of multi-storey or high-rise buildings, pour concrete in the cavity formed by two formworks, after the cast-in-place concrete is hardened, the reinforced truss gypsum board with insulation layer is combined Without demolition, it bears the external load together with the cast-in-place wall, thus becoming a ...

Embodiment 3

[0041] The invention can be used as the bottom form of the prefabricated wall panels or prefabricated floor slabs of multi-storey or high-rise buildings. The construction process is as follows: A reinforced truss gypsum board with insulation layer and a new formwork without dismantling (hereinafter referred to as: gypsum formwork) are placed horizontally on the formwork of the factory → side formwork installation → steel bar binding and pipeline laying → acceptance → concrete Pouring→maintenance→solidification and forming→remove the side formwork. So far, the present invention is used as a permanent formwork for prefabricated walls or prefabricated floors of multi-storey or high-rise buildings. Concrete is poured on the base form. , it bears the external load together with the poured concrete, thus becoming a new prefabricated wall or prefabricated floor with insulation layer.

Abstract

The invention discloses a reinforced truss gypsum plate with an insulation layer, a novel dismantling-free formwork and their construction method. The reinforced truss gypsum plate comprises a bottom plate made of a gypsum plate and the insulation layer disposed below the bottom plate, reinforced trusses in a plurality of rows are disposed above the bottom plate, and the steel trusses are parallel to or perpendicular to one another. By combining the insulation layer and the dismantling-free formwork through pasting or through ties, the insulation layer is made into a part of the dismantling-free formwork. The dismantling-free formwork is a reinforced truss gypsum formwork with the insulation layer, formed by setting the reinforced trusses composed of cross beams and supports on gypsum plate, casting feet of the supports into the gypsum plates and allowing the gypsum plates to harden. During construction, the reinforced truss gypsum formwork with the insulation layer is lifted to a specific floor to serve as a wall exterior formwork, after mounting of temporary supporting, tying of rebars and layout of pipelines, a wall interior formwork is mounted, and concrete is poured into a chamber formed by the exterior formwork and the interior formwork to form an insulation wall.

Description

technical field [0001] The invention relates to a floor slab or a wall slab for building construction, in particular to a reinforced truss gypsum board with an insulating layer, a new formwork without dismantling and a construction method. Background technique [0002] In my country's housing construction, the requirements for energy saving of houses are getting higher and higher, and the common and widely used technology is external wall thermal insulation technology, such as: polystyrene foam plastic board thin plaster external wall external thermal insulation system. At present, most of these external wall insulation technologies have problems such as uneven construction quality and difficult supervision, and even more serious accidents such as external wall insulation falling off and fires during construction. One of the important reasons for this is that the external thermal insulation technology of external walls is used for high-altitude operations, the construction c...
