Abstract
A stiffened ribbed pre-stressed V-shape slab comprises two upper beams, two diagonal webs and a bottom beam. The stiffened ribbed pre-stressed V-shape slab is characterized in that pre-tensioned pre-stressed strand wires are embedded longitudinally in the bottom beam and longitudinal stiffening ribs are arranged longitudinally at certain intervals on the lower sides of the inclined webs. The inclined webs of the stiffened ribbed pre-stressed V-shape slab utilize slabs which are provided with stiffening ribs. According to this arrangement, the correct thickness of the inclined webs is reduced, the self-weight of the V-shape slab is alleviated, and the large-span bending moment is reduced substantially, and accordingly, the consumption of steel materials is reduced. Longitudinal steel bars of the V-shape slab are conducted according to pre-tensioned pre-stressed, and accordingly, the V-shape slab can be easy to construct. Stirrups utilize spiral hoops so that the steel bars can be convenient to bind, and accordingly, the compressive strength of concrete in the compression zone is increased.
Description
Technical field
The utility model relates to a kind of roof panel, relates in particular to a kind of prestressed reinforced concrete roof panel of large span.
Background technology
Large-span steel-reinforced concrete roof plate adopts the lighter T plate of deadweight and goose-shaped board usually, and goose-shaped board because of its from heavy and light, stress performance is good, cost is lower than T plate, with the obvious advantage, a kind of goose-shaped board of patent No. 02285861.X publicity, the method for employing plate face ribbing or dull and stereotyped root haunch, the Rigidity of solution swash plate, but goose-shaped board is take post-stress as main at present, its rib of the goose-shaped board of plate face ribbing is made difficulty, and the post-tensioned prestressing operation is many, and construction quality is unstable, in addition because different plate sectional dimension difference is large, the template versatility is poor, and cost is higher, and the light-duty goose-shaped board of ribbing yet there are no report at the bottom of a kind of plate.
The content of utility model
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of, mould highly versatile few from heavy and light, specification, cost is low and the prestressed v shape slab with ribbing of easy construction.
According to the prestressed v shape slab a kind of with ribbing that the utility model provides, comprise beam suitable for reading, oblique web and bottom end rail, described bottom end rail longitudinally is embedded with the pretensioned prestressing steel hinge line, and tiltedly the web downside longitudinally is provided with vertical stiffening rib at a certain distance.
The prestressed v shape slab a kind of with ribbing that provides according to the utility model also has following attached technical characterictic:
Described vertical stiffening rib upper end links to each other with beam suitable for reading, and the lower end links to each other with bottom end rail.
Vertically be embedded with pretensioned prestressing steel strand or steel wire in the described beam suitable for reading.
Level is provided with some cross-ties between the described beam suitable for reading, and pull bar is the steel bar concrete rod member.
Be embedded with the two-way concrete slab welded mesh in the described oblique web, vertical stiffening rib bottom is embedded with and the equidirectional reinforcing bar of rib, and the vertical reinforcement of described reinforcing bar and net sheet muscle stretches into the bottom end rail certain-length.
Described beam suitable for reading and bottom end rail all are embedded with rectangle or round screw thread hoop.
Described oblique web middle part is provided with at least one rectangle or circular lightlng hole, is stamped glass on the lightlng hole.
Liangqi side, described lower end and bottom surface are rectangular, wide 200-300mm side, bottom surface height 100-600mm.
Described beam lateral surface suitable for reading is embedded with built-in fitting.
Provide a kind of prestressed v shape slab with ribbing compared with prior art to have following advantage according to the utility model: at first, oblique web of the present utility model adopts ribbed panel, oblique web converting thickness is reduced, make the goose-shaped board weight reduction, the moment of flexure of Span Slab just can significantly reduce, thereby reduces rolled steel dosage; Secondly, longitudinal reinforcement of the present utility model all adopts the pretensioned prestressing easy construction, and stirrup adopts spiral hoop, and reinforcing bar binding is convenient, and the compressive strength of pressure zone concrete improves; Again, angle of slope and the size of oblique web of the present utility model are fixed, and only the end opening beam section changes, and the goose-shaped board of the different spans of 15-24m can adopt same set of template construct, and the template amortization charge can greatly reduce; At last, the utility model beam suitable for reading and bottom end rail all adopt prestressing force, work with cracking not in the member, the improving from water resistance of goose-shaped board.

The specific embodiment
Referring to Fig. 1 to Fig. 4, that the utility model provides is a kind of embodiment of prestressed v shape slab with ribbing, comprise beam 1 suitable for reading, oblique web 2 and bottom end rail 3, described bottom end rail 3 longitudinally is embedded with pretensioned prestressing steel strand 4, and tiltedly web 2 downsides longitudinally are provided with vertical stiffening rib 21 at a certain distance.The pretensioned precast element that long collimation method is made, production efficiency is high, easy construction, cost reduces, and vertical stiffening rib 21 is for strengthening the strength and stiffness of oblique web 2, the converting thickness of oblique web 2 alleviated reach the purpose that alleviates deadweight.
Referring to Fig. 3, in above-described embodiment that the utility model provides, beam 1 interior pretensioned prestressing steel strand or the steel wire 5 of vertically being embedded with suitable for reading, goose-shaped board produced antiarch when these steel strand or steel wire 5 put for the prestress wire 4 on the balance bottom end rail 3, prevent beam 1 concrete cracking suitable for reading, the simultaneously reinforcing bar setting of convenient beam 1 suitable for reading.
Referring to Fig. 1, in above-described embodiment that the utility model provides, level is provided with some cross-ties 6 between the described beam 1 suitable for reading, and pull bar is the steel bar concrete rod member, oblique web 2 damaged when cross-tie 6 can prevent that goose-shaped board transportation and lifting stage from bumping, or the crack appears in root.
Referring to Fig. 3, in above-described embodiment that the utility model provides, beam 1 suitable for reading all is embedded with rectangle or round screw thread hoop 9 or 91, rectangle or not only easy construction of round screw thread hoop 9 or 91 with bottom end rail 3, and constraint concrete ability is strong, can improve the concrete compressive strength of beam 1 suitable for reading and bottom end rail 3.
