Description

A kind of fiber rib prestressed ground tackle unit and the rib prestressed ground tackle of fiber thereof
Technical field
The present invention relates to a kind of fiber rib prestressed ground tackle unit and the rib prestressed ground tackle of fiber thereof, be applied to the concrete prefabricated element forming field.
Background technology
Existing metal ribs prestressed anchor is made of anchor slab, anchor plate etc., and the backguy of reinforcing bar anchor is fixed on the anchor slab by the anchor clamp tool of special use.This mode needs with specific purpose tool the anchor backguy to be fixed one by one with the anchor clamp tool, and site operation bothers, efficient is low.In addition, the concrete system of metal anchors exist corrosion resistance poor, not diamagnetic, from great problem.The rib prestressed ground tackle of existing a kind of fiber adopts in the hole tooth, carries out the anchoring principle of clamping carbon fibre bar, and characteristics high with carbon fiber fragility and that shear behavior is low are conflicted, and cause anchoring property to descend; The rib prestressed ground tackle of existing another kind of fiber adopts extruding anchoring principle, exist carbon fibre bar to be subjected to powerful external force extruding, and generation tissue looseness or microstructure are loose, making loosens forms the molecule that profile is irregular, have seamed edge, filament is produced the possibility of cutting, cause anchoring property to descend equally.
Summary of the invention
At above-mentioned prior art problems, task of the present invention provides a kind of fiber rib prestressed ground tackle unit and the rib prestressed ground tackle of fiber thereof, to improve the anchoring property of the rib prestressed ground tackle of fiber, makes things convenient for site operation simultaneously.
For finishing above-mentioned task, technical scheme of the present invention is: the rib prestressed ground tackle of a kind of fiber unit, this ground tackle unit is made of the gasket ring with the axial screens assembling of outer anchor ring of plug-in mounting in the endoporus with the outer anchor ring of endoporus, outer anchor ring, the gasket ring at least two ring lobes of serving as reasons fasten the branch body structures form, the endoporus of gasket ring be arranged to can with the structure of fiber muscle immovable fitting.
The endoporus of described outer anchor ring is a bellmouth, and the outer surface of gasket ring is the conical surface that cooperates with the endoporus of outer anchor ring, and the endoporus of gasket ring is and wealthy mouthful of direction of the endoporus of outer anchor ring taper hole in the same way, the dead in line of each taper hole.
The endoporus of described outer anchor ring is a straight hole, and the outer surface of gasket ring is the cylinder that cooperates with the endoporus of outer anchor ring, and an end of gasket ring is provided with and the spacing ring edge that cooperates of an end of outer anchor ring, and the endoporus of gasket ring is that wealthy mouthful of direction is at the taper hole of ring along an end.
Need to be installed with a fiber muscle in the zone of anchoring in the internal taper hole of gasket ring, around the fiber muscle bossed cone segments is set, cone segments cooperates assembling with the internal taper hole of gasket ring.
Corresponding with the rib prestressed ground tackle of above-mentioned fiber unit, the present invention has also adopted the rib prestressed ground tackle of a kind of fiber, this ground tackle comprises anchor slab, evenly be provided with anchor hole in the anchor slab, be fitted with gasket ring in the anchor hole of each anchor slab with the axial screens assembling of anchor slab, the gasket ring at least two ring lobes of serving as reasons fasten the branch body structures form, the endoporus of gasket ring be arranged to can with the structure of fiber muscle immovable fitting.
Each anchor hole of described anchor slab is a bellmouth, and the outer surface of each gasket ring is the conical surface that cooperates with the anchor hole of anchor slab, and the endoporus of gasket ring is and anchor hole wealthy mouthful of direction taper hole in the same way, the endoporus of gasket ring and the dead in line of anchor hole.
Each anchor hole of described anchor slab is a straight hole, and the outer surface of gasket ring is the cylinder that cooperates with anchor hole, and an end of gasket ring is provided with and the spacing ring edge that cooperates of an end of anchor hole, and the endoporus of gasket ring is that wealthy mouthful of direction is at the taper hole of ring along an end.
Need to be installed with a fiber muscle in the zone of anchoring in the internal taper hole of gasket ring, around the fiber muscle bossed cone segments is set, cone segments cooperates assembling with the internal taper hole of gasket ring.
Described anchor slab is a flat board, and the axis of each anchor hole is parallel to each other.
Described anchor slab is a spherical plate, and the extended line of the axis of each anchor hole intersects at the centre of sphere point of this sphere.
Because the rib prestressed ground tackle of fiber of the present invention unit, the gasket ring with the axial screens assembling of outer anchor ring by plug-in mounting in the endoporus with the outer anchor ring of endoporus, outer anchor ring constitutes, gasket ring is served as reasons two encircle the branch body structures that the lobes fastening forms at least, the endoporus of gasket ring be arranged to can with the structure of fiber muscle immovable fitting, during use, can earlier the fiber muscle be passed the endoporus of outer anchor ring, the gasket ring of the axial screens assembling of interior plug-in mounting of the endoporus of anchor ring and outer anchor ring outside promptly can pass through the fiber muscle cone-shaped inner hole of the protuberance cone immovable fitting of its termination setting at gasket ring then.This mode is constructed simply, the anchoring reliable durable.In addition, fiber ground tackle system exists anticorrosive, diamagneticization, the little advantage of deadweight.
