Abstract
The present invention relates to a corrugated plate web girder. The structure of the corrugated plate web girder comprises an upper flange plate, a lower flange plate and a corrugated web. The corrugated plate web girder has the following characteristics: prestressed ribs, which are fixed on girder end plates by anchors, are arranged on the corrugated web; or reinforced rib plates with holes are arranged on both sides of the corrugated web; and the prestressed ribs pass through the reinforced rib plates and are fixed on the reinforced rib plates of both ends by the anchors. The corrugated plate web girder has the following advantages: the corrugated plate web girder adopts the prestressing technology, so the bearing capability of the girder structure is enhanced; the weight is light, so the corrugated plate web girder can be adapted to a large span; and the corrugated plate web girder has good designability and practicability.

Summary of the invention
Technical problem to be solved by this invention provides a kind of Waveform plate web girder, adopts prestressing technique, improves the supporting capacity of Waveform plate web girder.
One of technical scheme of technical solution problem of the present invention is: a kind of Waveform plate web girder comprises top flange plate 1, bottom wing listrium 2 and corrugated web 3, on corrugated web 3 porose 31, at the two ends of beam beam end plate 4 is arranged, beam end plate 4 and top flange plate 1, bottom wing listrium 2 and corrugated web 3 link together; Presstressed reinforcing steel 5 passes the hole 31 on the corrugated web, through being fixed on by anchor 6 on the beam end plate 4 at beam two ends after the stretch-draw.
The another technical scheme of technical solution problem of the present invention is: a kind of Waveform plate web girder, comprise top flange plate 1, bottom wing listrium 2 and corrugated web 3, reinforcement floor 7, the hole 71 on the reinforcement floor, presstressed reinforcing steel 5 and anchor 6 are formed, the upper and lower end of corrugated web 3 is provided with parallel top flange plate 1 and bottom wing listrium 2, in corrugated web 3 both sides, frange plate 1 and bottom wing listrium 2 interbody spacers are provided with reinforcement floor 7, reinforcement floor 7 and top flange plate 1, bottom wing listrium 2 and corrugated web 3 link together; Presstressed reinforcing steel 5 passes the hole 71 on the reinforcement floor 7, through being fixed on by anchor 6 on the beam end plate 4 at beam two ends after the stretch-draw.
Said presstressed reinforcing steel is that metal material is made or carbon fibre material is made.
Said corrugated web is made by metal material or the resin-based fibre reinforced plastics are made.
Every the line style of passing the presstressed reinforcing steel of corrugated web is low between the senior middle school of two, and promptly recess upwards; The presstressed reinforcing steel that passes corrugated web can be one or more.
Every the line style of passing the presstressed reinforcing steel of a side rib plate is low between the senior middle school of two, and promptly recess upwards; Presstressed reinforcing steel in corrugated web one side can be one or more, and the floor of both sides and presstressed reinforcing steel are for being symmetrical arranged.
Compared with prior art, advantage of the present invention is:
1. adopt prestressing technique, improved the supporting capacity of girder construction.
2. in light weight, can be used for the bigger footpath of striding.
3. can obtain different bending rigidities with prestressed line style by the physical dimension of regulating corrugated web, have good designability and practicality.

The specific embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention being done one describes in detail:
As Fig. 1-3, a kind of Waveform plate web girder, by top flange plate 1, bottom wing listrium 2, corrugated web 3, the hole 31 on the corrugated web, beam end plate 4, presstressed reinforcing steel 5 and anchor 6 are formed; Beam end plate 4 is positioned at the two ends of beam, with top flange plate 1, bottom wing listrium 2 and corrugated sheet 3 link together, hole 31 is positioned at the bias plate portion of corrugated web 3, with respect to the hole of a presstressed reinforcing steel 5, reduce successively from two ends to the centre, presstressed reinforcing steel 5 passes the hole 31 on the corrugated web 3, through being fixed on by anchor 6 after the stretch-draw on the end plate 4 at beam two ends, form the line style that recess makes progress.Corrugated web 3 is made by metal material, and presstressed reinforcing steel 5 is made by metal or carbon fibre material.
Embodiment 2:
Substantially the same manner as Example 1, difference is, the presstressed reinforcing steel that has two recesses to make progress on the corrugated web.Presstressed reinforcing steel is made by carbon fibre material; Corrugated web is made by the resin-based fibre reinforced plastics.
