Abstract
The invention relates to a prestressed V-shaped board with a heat insulation layer. The prestressed V-shaped board with the heat insulation layer comprises inclined boards and a profiled beam which form a V-shaped member, and is characterized in that heat insulation blocks are longitudinally embedded at intervals at the lower side of each inclined board, and reinforcing ribs are vertically formed between the heat insulation blocks; and pretensioned prestressed stranded steel wires are longitudinally embedded in the profiled beam. The heat insulation layer and a concrete board are integrally cast and combined firmly, and the heat insulation performance of a roof board is good; the reinforcing ribs are arranged on the inclined web boards, so that the bending resistance thickness of the inclined web board is greatly improved, the board stiffness is increased, the panel is thin, the self-weight is light, and the amount of steel of the V-shaped board can be reduced; and meanwhile, the upper end and the lower end of the V-shaped board are matched with prestressed steel wires or stranded steel wires, so that the V-shaped board does not crack, and the self-waterproof performance of the board is good.
Description
Technical field
The present invention relates to a kind of Prefabricated slab of roof, relate in particular to a kind of Prefabricated reinforced concrete roof panel of long span building.
Background technology
Large-span steel-reinforced concrete roof adopts T plate or goose-shaped board usually, the insulation layer of the goose-shaped board roofing of using at present generally be located at plate above, complicated construction technique, quality of waterproof layer is difficult to guarantee, as spray insulation layer in the plate bottom, its cost is high, and surperficial impression is poor, in addition, tiltedly web adopts flat board or haunched slab usually, and plate thickness is large, from great, goose-shaped board deadweight moment of flexure is increased, increased quantity of reinforcement.A kind of light-duty goose-shaped board that carries insulation layer yet there are no report.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, and a kind of prestressed v shape slab of, easy construction low from heavy and light, good heat insulating, cost is provided.
According to a kind of prestressed v shape slab with the temperature layer provided by the invention, comprise that swash plate and profiled beam form the V character form component, described swash plate downside longitudinally the interval be embedded with heat insulating block, vertically form ribs between warming plate, longitudinally be embedded with the pretensioned prestressing steel hinge line in the profiled beam.
Also have following attached technical characterictic according to a kind of prestressed v shape slab with the temperature layer provided by the invention:
Be embedded with pretensioned prestressing steel hinge line or steel wire in the top concrete of described swash plate.
Be provided with some cross-ties between described two swash plate tops, pull bar is the steel bar concrete rod member.
Ribs bottom between the heat insulating block of described swash plate is furnished with reinforcing bar, and certain-length in the profiled beam is all stretched in the reinforcing bar lower end.
The upper surface of described swash plate is embedded with the two-way welding steel mesh reinforcement, and vertical muscle stretches into certain-length in the profiled beam.
Vertical two ends of described heat insulating block are step, and swash plate top and swash plate root certain distance are left in two ends up and down, and the heat insulating block upper surface is provided with the duck eye of some certain depths, and the heat insulating block material is XPS or EPS or lightweight aerated concrete.
The middle part of described swash plate is provided with a lightlng hole at least, and lightlng hole is rectangle or circle, is stamped glass on the lightlng hole.
Be embedded with the rectangular coil hoop in the described profiled beam body.Described plate body upper end is embedded with the spiral hoop of circle or rectangle.
Side and the bottom surface of described profiled beam meet at right angles, the wide 200-300 in bottom surface, side height 100-600.
The side, top of described swash plate is embedded with built-in fitting.
Compared with prior art have following advantage according to a kind of prestressed v shape slab with the temperature layer provided by the invention: at first, the insulation layer among the present invention and concrete plate are whole to be watered in conjunction with firm, and the roof boarding heat insulating heat-proof quality is good; Secondly, the present invention has improved the bending resistance thickness of oblique web greatly because oblique web is provided with stiffening rib, and panel stiffness strengthens, and panel is thin, from heavy and light, can reduce the steel using amount of goose-shaped board; Again, goose-shaped board of the present invention upper end, lower end all are furnished with compressor wire or steel strand, and goose-shaped board can not produce the crack, and plate is good from water resistance.In addition, the swash plate soffit is the plane, and the template that the making goose-shaped board is used is easy to process, and processing charges reduce; At last, stirrup of the present invention adopts spiral hoop, and the pressure zone compressive property improves and swash plate adopts the welded wire fabric sheet, and colligation efficient is high, and speed of application is fast, and plate is easily manufactured, and cost is low.

The specific embodiment
Referring to Fig. 1 to Fig. 4, the present invention provides is a kind of embodiment of the prestressed v shape slab with insulation layer, comprise that swash plate 1 and profiled beam 2 form the V character form component, described swash plate 1 downside longitudinally the interval be embedded with heat insulating block 11,11 of warming plates vertically form ribs 12, longitudinally are embedded with pretensioned prestressing steel hinge line 21 in the profiled beam 2.Heat insulating block 11 and swash plate concrete be whole to water together fixation, good heat insulating, and the ribs 12 of 11 formation of heat insulating block can improve rigidity and the bending resistance of swash plate 1, though plate thickness is large, the concrete converting thickness is little, from heavy and light.The goose-shaped board of pretensioned prestressing construction is compared materials such as having saved sleeve pipe, ground tackle with post-tensioned prestressing.Operation is simplified, and cost reduces.
Referring to Fig. 2, in the embodiment that the present invention provides, be embedded with pretensioned prestressing steel hinge line or steel wire 13 in the top concrete of described swash plate 1, the recurvation square and the antiarch that produce when these steel strand or steel wire can balance profiled beam 2 interior steel strand 21 be put make goose-shaped board top can not produce the crack.
Referring to Fig. 1, in the embodiment that the present invention provides, be provided with some cross-ties 3 between described two swash plate tops, pull bar is the steel bar concrete rod member, cross-tie 3 can prevent that goose-shaped board from bumping in transportation and when lifting damages swash plate 1 or the crack appears in root.
