Description
TECHNICAL FIELD
[0001] The utility model belongs to the reinforced concrete outdoor cantilever platform cold (heat) bridge prevention design technical field of new energy -saving building in severe cold area, especially relates to a kind of outdoor cantilever platform structure of broken bridge reinforced concrete. BACKGROUND
[0002] At present, the reinforced concrete outdoor cantilever platform of building is mostly formed by the structure that floor slab of building passes through outer wall. Energy -saving building outer wall insulation design is to paste insulation board on base wall. Since the common practice of reinforced concrete outdoor cantilever platform is that floor slab overhangs and passes through outer wall, the insulation layer pasted on outer wall is disconnected at this place, and the reinforced concrete cantilever platform cannot be fully covered with insulation board, which leads to the formation of cold (heat) bridge between indoor and outdoor of building, greatly weakening the overall insulation effect of building, and greatly affecting the energy -saving building energy consumption reduction index of building itself. SUMMARY
[0003] The utility model aims at solving the problem that the conventional reinforced concrete outdoor cantilever platform utilizes floor slab overhang and passes through outer wall structure, reinforced concrete cantilever platform cannot be fully covered with insulation board, leading to the formation of cold (heat) bridge between indoor and outdoor of building, to provide a kind of outdoor cantilever platform structure of broken bridge reinforced concrete, so that outer wall insulation system is continuously formed as a whole, and cold (heat) bridge is blocked.
[0004] To achieve the above-mentioned utility model purposes, the utility model provides a kind of outdoor cantilever platform structure of broken bridge reinforced concrete in severe cold area, including reinforced concrete cantilever platform plate, reinforced concrete edge beam, frame beam under building floor slab, reinforced concrete edge beam is overhanging outside on frame beam under building floor slab, and the overhanging length is the width of cantilever platform, and the top elevation is the top elevation of cantilever platform minus the thickness of cantilever platform plate, reinforced concrete cantilever platform plate is arranged on reinforced concrete edge beam, and the inner edge of reinforced concrete cantilever platform plate is spaced apart from building base wall, and the spacing is the thickness of base wall insulation board.
