Description
Technical field
The cladding heat-insulating load-bearing cantilevered plate docked with frame construction and prepare construction method, belongs to energy-conserving construction wall technology field, is specifically related to a kind of steam-pressing aero-concrete cladding heat-insulating load-bearing cantilevered plate and construction method thereof.
Background technology
In energy saving building technical field, the body of wall of space enclosing structure extensively adopts the building block of light cement base, as Autoclaved aerated concrete blocks GB11968-2006, foam concrete block JG/T266-2011.Because the compressive strength of light cement based block material, especially tensile strength are not high, body of building a wall can not bear the load of anchoring outdoor machine of air-conditioner, bay window etc.The structure discipline design of existing building construction, design steel concrete cantilevered plate class formation component (as air-conditioning shelf, bay window upper beam and leave from office, awning etc.) of having to.The steel concrete cantilevered plate of design is most cast-in-place with Vierendeel girder, frame column, floor together with, this cast-in-place, formwork complexity, construct loaded down with trivial details.Building energy conservation Specialty Design subsequently, these class armored concrete slabs of encorbelmenting must do the process cutting off heat bridge, and usually wrap up each exposed surface of these armored concrete slabs with heat barrier foam plate, set up fire resisting sand pulp layer, water barrier, very numerous and diverse, cost is very high.
With the Autoclaved aerated concrete slabs GB15762-2008 of steel mesh reinforcement, possessing load-bearing, heat insulation base attribute, is the current uniquely potential building unit serving as the partition heat bridge of cantilevered plate component.But, domestic and international steam-aerated concrete plate, lays because original Functional Design is only limited to be parallel on beam column direction, is using perpendicular on the direction of metope at present, especially, in the vertical direction on the surface of frame column, Vierendeel girder, positive connection cannot be realized.The class A of geometric unitA of encorbelmenting of region of interest can not be served as.In energy saving building field, the cantilevered plate component docked with building structure, load-bearing and heat insulation sheet material still belong to blank.
Need a kind of matrix to be the sheet material of light cement base, possess the heat-proof quality reaching energy-saving index, enough carrying mechanical properties, its structure can reliably, reasonably be docking integrally with the frame column of building, Vierendeel girder perpendicular on wall direction easily.Just can fill up this blank, solve such difficult problem that energy-saving house exists at present.For structure design and energy-saving design provide better platform, provide powerful support for and basis for energy saving building provides.
The overhanging component of building construction is the important composition element of outward appearance, and its position of laying and absolute altitude, except the consideration be effectively combined with frame construction, are subject to the restriction that appearance effect needs.That inserts frame beam column due to heat insulation cantilevered plate builds in die cavity, and the cross section material inserting the frame construction of Nodes will change, and having a strong impact on the intensity of insertion Nodes, is that building structure is definitely unallowed.Enough wide heat insulation cantilevered plate can by " overlap joint " to the upper surface of Vierendeel girder, soffit realization perpendicular to the reliable connection of building facade.But be only limitted to the corresponding absolute altitude of the end face of Vierendeel girder, bottom surface.The cantilevered plate that other absolute altitude must be laid, must not insert again in the die cavity of frame construction, can only take the method for docking.The breakthrough of docking technique, will solve the application bottleneck of the untethered of load-bearing cantilevered plate laying absolute altitude.Of great value technological progress meaning is produced to energy saving building.
