Abstract
The invention discloses a special shearing-resistance anchor bolt pair for an anchor group, comprising a basic part, an anchored part overlapped on the basic part and an anchor part for fixing the anchored part on the basic part, wherein the anchor part comprises an anchor bolt and an anchor nut; the anchor bolt successively passes through the anchored part and the basic part, and is fastened by the anchor nut; and the anchor bolt and the anchored part are closely matched through a cone pair. The shearing-resistance anchor bolt pair ensures that the anchor bolt and the anchored part are closely matched through the cone pair, avoids adverse impact on the anchor structure due to the thickness of the basic part, and can be applied to an outward overhung additional structure of a lamina basic part, and the matching structure of the cone can eliminate the radial clearance between the anchor bolt and the anchored part to increase the stress effect of the anchor bolt; and the anchor bolt pair has stronger adaptability to shearing force, so after the anchor bolt pair is anchored, the anchor part in the shearing-resistance anchor group can be synergically stressed to improve the anchor capability, reinforce the stability of the structure, and eliminate potential safety hazard.
Description
Technical field
The present invention relates to a kind of shearing resistance anchor structure, relate in particular to a kind of special shearing-resistance anchor bolt pair for anchor group.
Background technology
Adopt two members of the relative slippage of group's anchor anchored, be to use more a kind of structure at building engineering field, typical example is a newly-increased cantilevered structure flooring on original floor, and original floor is as basic part, newly-increased encorbelmenting as by anchoring piece generally adopted group's anchor anchor structure.Anchoring piece bears cross shear in this anchor structure, needs the anchoring piece cooperative bearing and has enough shear strengths.In the prior art, when reinforced concrete structure need outwards be encorbelmented newly-increased steel work flooring on floor structure, being connected between cantilever steel girder and the agent structure adopted the common anchor fixing structure to carry out group anchor anchoring usually; Common group's anchor structure is used for concrete thin plates and has following problem: basic part thickness can not satisfy the requirement of anchor structure to anchorage depth, and the structure after the anchoring is difficult to the anchoring strength requirement that reaches desirable; Owing to adopt the anchorage style of group's anchor, bear the dynamics inequality of shearing force and tensile stress between every group of anchoring piece and other anchoring piece, cause group anchor effect not obvious, the difference in application life of anchoring piece influences the stability of anchor structure, has tangible potential safety hazard.
Therefore, need improve existing special shearing-resistance anchor bolt pair for anchor group, use in the time of can being applicable to the relative slippage between restriction two members and bearing bigger shearing force, after the anchoring, can make the anchoring piece cooperative bearing in the shearing resistance group anchor, improve anchoring ability, strengthen stability of structure, eliminate because the potential safety hazard that the anchoring piece unbalance stress produces is specially adapted to reinforced by the hypodynamic plate-shaped basic part of curved carrying to bearing.
Summary of the invention
In view of this, the invention provides a kind of special shearing-resistance anchor bolt pair for anchor group, use in the time of can being applicable to the relative slippage between restriction two members and bearing bigger shearing force, after the anchoring, can make the anchoring piece cooperative bearing in the shearing resistance group anchor, improve anchoring ability, strengthen stability of structure, eliminate because the potential safety hazard that the anchoring piece unbalance stress produces is specially adapted to reinforced by the hypodynamic plate-shaped basic part of curved carrying to bearing.
A kind of special shearing-resistance anchor bolt pair for anchor group of the present invention, comprise basic part, be overlapped in basic part by anchoring piece and be used for and will be anchored in the anchoring assembly of basic part by anchoring piece, described anchoring assembly comprises anchor bolt and anchoring nut, described anchor bolt passes by anchoring piece and basic part fastening by the anchoring nut successively, described anchor bolt and by between the anchoring piece by the secondary snug fit of the conical surface.
Further, the described anchor bolt and the conical surface that cooperatively interacted between the anchoring piece are secondary is outer imperial palace minor structure;
Further, the radial clearance between described anchor bolt outer round surface and the basic part is cast with the anchoring sizing material;
Further, the thread segment external surface that described anchor bolt is corresponding with basic part is provided with dredging flow groove vertically;
Further, described anchor bolt is 1: 7.5 with the conical surface tapering that is matched by anchoring piece;
Further, described anchor bolt and the conical surface pair that is matched by anchoring piece comprise with anchor bolt is coaxial to be made the frustum of one and is arranged on by the bellmouth on the anchoring piece, is placed in bellmouth and its snug fit in the described frustum;
Further, described anchor bolt is the double end anchor bolt, and described anchoring nut comprises and be positioned at by the anchoring nut I of anchoring piece external surface and be positioned at the anchoring nut II of basic part external surface that described anchoring nut I and anchoring nut II all are provided with and axially put forth effort the hole.
Beneficial effect of the present invention is: the special shearing-resistance anchor bolt pair for anchor group of structure of the present invention, adopt anchor bolt to pass by anchoring piece and basic part fastening successively by the anchoring nut, and by conical surface pair make anchor bolt with by the anchoring piece snug fit, avoid owing to the adverse effect of basic part thickness problem anchor structure, can be applicable to the plate-shaped basic part newly-increased structure of outwards encorbelmenting, outwards increase the cantilevered structure floor such as concrete floor; The fit structure of the conical surface can be eliminated anchor bolt and by the radial clearance between the anchoring piece, increase the stressed effect of anchor bolt, has stronger adaptive capacity for shearing force, thereby after the anchoring, make the anchoring piece in the shearing resistance group anchor can cooperative bearing, improve anchoring ability, strengthen stability of structure, eliminate safe hidden trouble, be specially adapted to and avoid because plate-shaped basic part bearing capacity deficiency causes unstable phenomenon because of caused bearing reinforced by the hypodynamic plate-shaped basic part of curved carrying by anchoring piece.
