Description

A kind of composite wallboard structure with inside and outside Double layer thermal insulation
Technical field
This utility model belongs to technical field of buildings and in particular to a kind of composite wallboard with inside and outside Double layer thermal insulation Structure.
Background technology
Mainly adopt at present two kinds of structures form in domestic industry assembled precast concrete composite wallboard structure, first Planting composite wallboard is that monolayer overlaps, that is, outdoor section adopts prefabrication, and indoor section adopts molded-in-place, and centre is adopted again Use concrete cast-in-site, although this make to a certain degree embodies the advantage of prefabricated xoncrete structure, It is that industrialization assembled degree is not high.
Second composite wallboard is the double-layered wallboard of no thermal insulation structure, that is, outdoor and indoor section all adopt work Factory is prefabricated, and mid portion adopts concrete cast-in-site, and this make can embody prefabricated mixed to a great extent The advantage of Xtah Crude Clay structure, but there is problems with:1. indoor and outdoors prefabrication part is main structure in design principle Stress unit, due to production technology limit and stress on requirement, pre-erection cannot consider wall thermal insulating thermal insulation layer.2. room The centre of interior and outdoor pre-erection adopts cast-in-place concrete it is ensured that the globality of double-layered wallboard, due to prefabricated portion Divide and the concrete of cast-in-site has differences, so can not be fully equivalent to all adopt using the shear wall structure of composite wallboard With the concrete shear wall structure of cast-in-site, composite wallboard is made to be very restricted when applying in multi-rise building.3. Due to composite wallboard can not be fully equivalent to cast-in-place, so in multi-rise building apply when it is desired nonetheless to according to《Building aseismicity Design specification》Requirement, the edge of composite wallboard setting all using cast-in-place concrete shear wall stiffener, this Sample edge needs for arranging a lot of templates, governs the raising of composite wallboard assembly rate.
, there is industry makeup in the deficiency existing for the existing system of industrialization prefabricated concrete folding panel structure Join that formula degree is high, pre-erection cannot consider wall thermal insulating thermal insulation layer and composite wallboard can not be fully equivalent to cast-in-place etc. lacking Point, in order to overcome disadvantage mentioned above, we have developed a kind of composite wallboard structure with inside and outside Double layer thermal insulation, and this case is thus Produce.
Utility model content
This utility model provides a kind of composite wallboard structure with inside and outside Double layer thermal insulation, and indoor and outdoors factory is pre- System part is non-stress unit as wall thermal insulating thermal insulation layer, pre-erection, simply plays template during cast on-site concrete Effect, middle cast concrete parts are main bearing member, and design calculates all fairly simple, production technology and mounting process Convenient.
For reaching above-mentioned purpose, the technical scheme that this utility model is adopted is:One kind has inside and outside Double layer thermal insulation Composite wallboard structure, mainly include from outside to inside:Outdoor prefabricated thermal insulation thermal insulation layer, outdoor prefabricated thermal insulation thermal insulation layer distribution steel Muscle, steel bar girder, outside distribution of force reinforcing bar, cast-in-place concrete layer, inner side distribution of force reinforcing bar, indoor prefabricated thermal insulation thermal insulation layer Distribution bar, indoor prefabricated thermal insulation thermal insulation layer.
Wherein steel bar girder is mainly made up of three kinds of reinforcing bars, and outermost layer and innermost layer are heat insulation layer distributing bar, only Need to meet heat-insulation layer detailing requiments, be non-stress reinforcing bar;Middle two-layer is main steel bar stress, by calculating analysis really Determine the area of reinforcement;In order to ensure the globality of steel bar girder, two-layer heat-insulation layer distributing bar and middle two-layer steel bar stress it Between by abdominal part distributing bar connect integral, the section of truss as required, can be processed into yi word pattern plane girder, three Angular space truss or coffin truss.
The material of wherein outdoor prefabricated thermal insulation thermal insulation layer and indoor prefabricated thermal insulation thermal insulation layer employing is that thermal and insulating performance is good, From heavy and light, and there is the material of excellent mechanical performances, predominantly light foaming concrete material, light foam fiber concrete Deng new material;Prefabricated thermal insulation thermal insulation layer produces in factory lines and completes, and has good concrete curing condition it is ensured that pre- The thermal property of preparative layer and mechanical property meet design requirement.The thickness of prefabricated thermal insulation thermal insulation layer is according to different latitude energy saving calculation Requirement determine.
Wherein outdoor prefabricated thermal insulation thermal insulation layer and indoor prefabricated thermal insulation thermal insulation layer setting distribution bar and distributing bar composition Reinforced mesh, be connected integral with agent structure by steel bar girder, can make heat insulation layer pour into a mould concrete when play The effect of template, can guarantee that heat insulation layer will not fall off in life-time service again.
The main steel bar stress of two-layer and inside and outside two-layer distribution bar, steel area face wherein inside and outside cast-in-place concrete layer setting Amassing to carry out calculating according to Structure Design Software and determine, being attached further through steel bar girder, so being fully equivalent to cast-in-place shearing Wall construction.
As the setting further of such scheme, it is fully equivalent to cast-in-place shear wall structure in order in stress, inside and outside double Composite wallboard structure and the floor coupling part of layer insulation, setting composite wallboard strengthens anchor bar it is ensured that floor and folded Close wallboard to be reliably connected.
As the setting further of such scheme, the present invention is overflow in prefabricated thermal insulation thermal insulation layer position setting composite wallboard and is starched Hole it is ensured that middle cast-in-place concrete layer can shock in pouring closely knit.Simultaneously in order to ensure composite wallboard in transportation Interplate sealing when safety and construction peace turn, arranges flexible rubber bar in prefabricated thermal insulation thermal insulation layer edge surrounding, both permissible Play cushioning effect, can ensure that sealing again, and heat insulation layer is not allowed when expanding with heat and contract with cold to be also easy to produce crack yet.
