Abstract
A flange anchor device for steel sleeve reinforced concrete circular pier, comprises the flange of band 12 anchor hole, 12 stiffeners and 12 crab-bolts; Described flange is welded in steel sleeve diapire, and described stiffener connects steel sleeve lower end outer wall and flange, and flange is anchored in pier footing through anchor hole by described crab-bolt.Steel sleeve is anchored in concrete bridge pier foundation by the utility model, improves the supporting capacity of bridge pier, and simple and reasonable, practical, cost is low, and is convenient to install.
Description
Technical field
The utility model relates to a kind of anchor device, is specifically related to a kind of flange anchor device of steel sleeve reinforced concrete circular pier.
Background technology
When utilizing steel sleeve to fill the self-compacting concrete reinforced concrete circular pier of high fluidity, if do not carry out anchoring to bottom steel sleeve, anchored force is not had between steel sleeve and concrete bridge pier foundation, this can reduce the intensity of concrete circular bridge pier, rigidity and stability that steel sleeve is reinforced, thus cause the supporting capacity of concrete pier greatly to reduce, when running into the emergency situations such as overload, shock and earthquake, concrete circular bridge pier is easily damaged.
Summary of the invention
The utility model is for the problems referred to above, and provide a kind of simple and reasonable, supporting capacity is strong, and practical, cost is low, is convenient to the flange anchor device of the steel sleeve reinforced concrete circular pier installed.
The utility model is realized by following technical measures:
A flange anchor device for steel sleeve reinforced concrete circular pier, comprises flange, stiffener and crab-bolt.
Described flange internal diameter is identical with reinforced steel sleeve external diameter, flange flange width is 1/5 ~ 1/4 of flange internal diameter, thickness is 2 ~ 2.5 times of steel sleeve wall thickness, and flange is 10 ~ 15 deciles circumferentially, to arrange the anchor hole of diameter 18mm with inside and outside edge apart from equal place.
Described stiffener adopts Q235B structural section, and thickness is identical with flange thickness.
Described crab-bolt adopts M16*190mm type chemical anchor bolts.
Flange is welded on the diapire of steel sleeve, steel sleeve lower end outer wall is connected by welding 12 stiffeners circumferentially distributed with flange, and stiffener is positioned at the centre position of adjacent two anchor hole.The steel sleeve of above-mentioned diapire welding flange is coated at concrete circular bridge pier, flange 12 chemical anchor bolts is anchored in concrete bridge pier foundation, completes the anchoring to steel sleeve.
The beneficial effects of the utility model are:
1, adopt above-mentioned anchor device, steel sleeve bottom welding flange, and be provided with anchor hole on flange, this greatly facilitates steel sleeve and is connected with concrete bridge pier foundation.
2, steel sleeve lower end is connected by welding stiffener with flange, is conducive to the intensity of raising steel sleeve, rigidity and stability, thus the consolidation effect of Concrete Structure circular pier.
3, the thickness of the utility model flange in the bottom dish is 2 ~ 2.5 times of steel sleeve wall thickness, ensure that the intensity of flange.
4, the utility model is simple and reasonable, practical, and cost is low, and is convenient to install.
Accompanying drawing explanation
Fig. 1 is for utilizing structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is the axial section of the utility model anchoring steel sleeve.
Above in each figure, 1-steel sleeve, 2-flange, 3-stiffener, 4-crab-bolt.
Detailed description of the invention
For technical characterstic of the present utility model can be clearly demonstrated, below by detailed description of the invention, and by reference to the accompanying drawings, the utility model is set forth.
Test specimen pier stud circular cross section diameter is 260mm, and post height is 2000mm, and bottom is fixed pier square-section and is of a size of 520mm × 520mm, and pier height is 500mm; Concrete adopts C30 strength grade, and vertical muscle adopts II level screw-thread steel Φ 12, and stirrup adopts I level steel Φ 6@40 spiral hoop.
As shown in Figure 2, the flange anchor device of a kind of steel sleeve reinforced concrete circular pier of the present embodiment, comprises 1-flange, 2-stiffener, 3-crab-bolt.The steel sleeve external diameter reinforcing circular concrete pier is 600mm, wall thickness 1.7mm.Flange that is 4mm is thick, flange width 130mm is welded on the diapire of steel sleeve, and steel sleeve lower end outer wall is connected by the stiffener that welding 12 4mm are thick with flange, and stiffener is positioned at the centre position of adjacent two anchor hole.The lifting of the steel sleeve of above-mentioned bottom welding flange is coated at concrete circular bridge pier, the anchor hole of 12 default diameter 18mm is each passed through with 12 M16*190mm type chemical anchor bolts, flange is anchored in concrete bridge pier foundation, completes the anchoring to steel sleeve.Fill the self-compacting concrete of high fluidity between steel sleeve and concrete circular bridge pier, complete the reinforcing to concrete circular bridge pier.
MTS experimental facilities is adopted to carry out Frequency Cyclic Static Loading to without flange anchoring with through the concrete circular bridge pier of flange anchoring respectively, test display, compared with the concrete circular bridge pier without flange anchoring, after steel sleeve cripling bottom the concrete circular bridge pier of flange anchoring, also experienced by flexing position steel sleeve and concrete is peeled off, crab-bolt tensile failure, until crab-bolt tension causes the process of seat concrete cracking destruction, the yield load of concrete circular bridge pier, maximum load and last ultimate load all increase, consolidation effect is remarkable.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, for a person skilled in the art, can according to technical scheme described above and design, the utility model is modified or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
