Abstract
The utility model relates to a prestressing waveform plate web girder structure, belonging to the technical field of girder structure, which is composed of a top flange plate 1, a bottom flange plate 2, a waveform plate web 3, a reinforced ribbed slab 4, a hole 41 on the reinforced ribbed slab, a prestressing tendon 5 and an anchoring device 6, wherein the reinforced ribbed slab 4 is connected with the top flange plate 1, the bottom flange plate 2 is connected with the waveform plate web 3; the prestressing tendon 5 penetrates through the hole 41 on the reinforced ribbed slab 4 at two sides of the waveform plate web 3, is tensioned and is fixed on the reinforced ribbed slab at two ends of the girder via the anchoring device 6. The utility model has the advantages that the prestressing waveform plate web girder structure adopts prestressing technique to improve the bearing capacity of the girder structure; the prestressing waveform plate web girder structure has low weight and can be used for large span; and the prestressing waveform plate web girder structure r is designable and practical.
Description
Technical field
The utility model belongs to the girder construction field, relates in particular to prestressing force corrugated web girder construction.
Background technology
Existing girder construction is generally i beam, and it is made of with two blocks of parallel frange plates up and down vertical web, and web commonly used is flat web, but its shearing resistance buckling strength and shear-carrying capacity all have much room for improvement.Waveform plate web girder has the high advantage of shearing resistance buckling strength, adopts the less corrugated sheet of thickness just can make beam obtain higher shear-carrying capacity, thereby can improve the deadweight of fine strain of millet structure bearing capacity and reduction equipment effectively.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Waveform plate web girder, adopts prestressing technique, has improved the supporting capacity of Waveform plate web girder.
The technical scheme of the utility model technical solution problem is as follows:
A kind of Waveform plate web girder, by top flange plate 1, bottom wing listrium 2, corrugated web 3, reinforcement floor 4, hole 41 on the reinforcement floor, presstressed reinforcing steel 5 and anchor 6 formed, and the upper and lower end of corrugated web 3 is provided with 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 4, reinforcement floor 4 and top flange plate 1, bottom wing listrium 2 and corrugated web 3 link together; Presstressed reinforcing steel 5 passes the hole 41 on the reinforcement floor 4, through being fixed on by anchor 6 on the reinforcement floor 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 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, the utility model has the advantages that:
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.
Description of drawings
The structure three-dimensional schematic diagram of Fig. 1 the utility model embodiment 1.
The structural representation of Fig. 2 the utility model embodiment 1.
The structural representation of Fig. 3 the utility model embodiment 1.
Among the figure: 1 top flange plate; 2 bottom wing listriums; 3 corrugated webs; 4 reinforcement floors; Hole on the 41 reinforcement floors; 5 presstressed reinforcing steels; 6 anchors.
The specific embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention being done one describes in detail:
Embodiment 1:
With reference to Fig. 1-3, a kind of Waveform plate web girder, by top flange plate 1, bottom wing listrium 2, corrugated web 3, reinforcement floor 4, hole 41 on the reinforcement floor, presstressed reinforcing steel 5 and anchor 6 formed, and is provided with polylith reinforcement floor 4 in the bilateral symmetry of corrugated web 3, stiffened panel 4 and top flange plate 1, bottom wing listrium 2 and corrugated web 3 link together.Presstressed reinforcing steel 5 passes the hole 41 on the stiffened panel 4 of corrugated web 3 both sides, forms the line style that recess makes progress, through being fixed on by anchor 6 on the reinforcement floor at beam two ends after the stretch-draw.Corrugated web 3 is made by metal material, and presstressed reinforcing steel 5 is made by metal material or carbon fibre material.
Embodiment 2:
Substantially the same manner as Example 1, difference is that the reinforcement floor has a plurality of holes, the presstressed reinforcing steel that the both sides of corrugated web respectively have two recesses to make progress.Corrugated web is made by the resin-based fibre reinforced plastics, and presstressed reinforcing steel is made by metal or carbon fibre material.
The utility model is not limited to these disclosed embodiments, and the present invention will cover the scope described in the patent book, and the various modification of claim scope and equivalence variation.
