Embodiment 1

[0045] It is used for the air conditioner external unit shelf on the right side of the balcony of a residential building. It is designed as a shelf for superiors, and three air-conditioning outdoor units are placed, with a maximum load of 350KG; the elevation of the cantilevered slab is flush with the floor slab in the architectural shape design, and some sections are connected to the frame columns.

[0046] Refer to attached figure 1 : The design elements of the cantilever slab are: the length of the cantilever slab is 1800mm, the width is 600mm, and the thickness is 120mm; 3 B05 grade autoclaved aerated concrete, the high-density layer 7 of the cantilever slab is 40mm thick and the density is 700 kg / m 3 B07 grade autoclaved aerated concrete; steel mesh is distributed inside the cantilever slab, and the side of the cantilever slab connected to the building is provided with an interface end 16. The threaded steel bars 9 at the interface end 16 are T12×6 screws with a spacing...

Embodiment 2

[0059] The implementation conditions and steps are the same as in Example 1, except that the autoclaved aerated concrete composite structure has a density of 300kg / m 3 B03 grade autoclaved aerated concrete with a density of 800 kg / m 3 The two-layer structure of B08 grade autoclaved aerated concrete; the cantilevered slab is hoisted to the position required by the design, and the formwork construction of the frame column and frame beam and the positioning and fixing of the cantilevered slab are completed; the frame column is poured first, and then the Pouring the frame beam, through the frame column and frame beam concrete pouring twice, the cantilever slab and the frame structure are connected together.

Embodiment 3

[0061] Implementation conditions and steps are the same as in Example 1, except that the autoclaved aerated concrete composite structure is a density of 400kg / m 3 B04 grade autoclaved aerated concrete with a density of 600 kg / m 3 The two-layer composite structure of B06 grade autoclaved aerated concrete; the perforated plate 15 is an M10 nut, which is welded on the fixed plate 14.

Abstract

The invention discloses a multilayer load bearing heat-insulated cantilever plate butted with a frame structure and a preparation and construction method, and belongs to the technical field of wall body technology of energy-saving buildings. The cantilever plate is characterized in that the cantilever plate adopts autoclaved aerated concrete and has a multilayer structure, and the side face of the cantilever plate butted with the frame structure is an interface end (16). The method for preparing the cantilever plate comprises the following steps of: in an existing embryonic body mould of the autoclaved aerated concrete, using separators to realize partitioning; respectively pouring slurries with different densities, growing, and inserting a rebar fabric; after cutting the embryonic body, screwing or grafting rebars with a certain-length exsertion on the rebar fabric, so that the interface end (16) is formed. When the multilayer load bearing heat-insulated cantilever plate is butted with the frame structure, the rebars with the certain-length exsertion are poured in the frame structure, so that reliable connection is formed. A wall body cantilever structure formed by the method in the invention has heat-insulating property and enough bearing mechanical property which meet 65% of building energy conservation indexes, the arrangement of elevation of the cantilever plate overcomes the limitation of choice of a bonded structure elevation.

Description

technical field [0001] A multi-layer load-bearing heat-insulating cantilever slab docked with a frame structure and a preparation and construction method belong to the technical field of energy-saving building wall technology, and specifically relate to an autoclaved aerated concrete multi-layer load-bearing heat-insulation cantilever slab and a construction method thereof. Background technique [0002] In the field of energy-saving building technology, lightweight cement-based blocks are widely used for walls of enclosure structures, such as autoclaved aerated concrete blocks GB11968-2006, foam concrete blocks JG / T266-2011. Since the compressive strength, especially the tensile strength, of the lightweight cement-based block material is not high, the wall body cannot bear the load of anchoring the external unit of the air conditioner and the bay window. The current professional structural design of housing construction has to design reinforced concrete cantilevered slab str...
