Abstract
The invention provides a root division anchoring piece which is characterized in that a connection body is connected with two or more chemical anchor bolts or expansion bolts, and the connection body is provided with threaded holes or directly welded with other anchoring pieces. The root division anchoring piece is used for solving the problem that the initial punching depth can not be reached in anchoring due to blocking.
Description
Technical field
An anchoring piece, for solving the problem that anchoring by concrete screw-bolt is constructional difficulties while running into the obstructions such as reinforcing bar.
Background technique
Bolt anchoring is when reinforced concrete; often can run into bolt and run into the problem that reinforcing bar cannot insert bolt completely; traditional solution is beat inclined hole or fix in other position perforates; open the bolt strained change of inclined hole; easily come off, rupture; and in other position perforates, also cause the stressed change of bolt, produce unsafe factor.
Summary of the invention
An anchoring piece, is characterized in that: on a connecting body, be connected with two or more chemical anchor bolts or expansion anchor, connecting body itself can have tapped hole, or direct and other anchoring pieces welding; Described connecting body is Cylindrical object, can have tapped hole or directly weld external piece on it; Described two or more chemical anchor bolts or expansion anchor, its net sectional area sum equates with the anchoring piece of outer company.
In the time of can fine solution crab-bolt anchoring while using root division anchoring piece to use, run into reinforcing bar or bar and be cannot smooth construction situation.And because its sectional area increases, it is large that the stress cone in concrete becomes, and reduced the stress in unit area, therefore improved Security.
Accompanying drawing explanation
Fig. 1 is the root division anchoring piece schematic diagram that is threaded through hole.
Fig. 2 is the root division anchoring piece schematic diagram that there is no tapped through hole.
Fig. 3 is a kind of embodiment's signal of root division anchoring piece.
Shown in Fig. 1, Fig. 2, be 1. root division anchoring piece, be 2. reinforcing bar or other obstructions in concrete.When construction, when punching runs into reinforcing bar or other obstructions, cause crab-bolt to anchor into completely, now, hole is expanded, and in surrounding's punching of bar, again root division anchoring piece is inserted, utilize its a plurality of chemical anchor bolts or expansion anchor of separating to walk around bar, be fixed on original position.Because the net sectional area of a plurality of chemical anchor bolts that separate or EXPANSION ANCHOR BOLTS equates with first anchoring piece sectional area, therefore its intensity also equates, can substitute former anchoring piece completely fixes, and because its sectional area increases, it is large that stress cone in concrete becomes, reduced the stress in unit area, therefore improved Security.
Embodiment
As shown in Fig. 3 (a.), when punching, run into bar, cannot reach the former punching degree of depth.Now, with reamer, foramen primum is expanded, and in bar punching around, several expansion anchors that the diameter of punching is connected with root division anchoring piece or the required aperture of chemical anchor bolts equate, as shown in Fig. 3 (b.).Then root division anchoring piece is inserted in the hole of accomplishing fluently, as shown in Fig. 3 (c.).Finally former anchoring piece is connected with root division anchoring piece, shown in Fig. 3 (d.) is that root division anchoring piece and former anchoring piece adopt screw-thread fit.
This embodiment is a kind of typical mode of execution, does not limit its concrete form, as: the Placement between root division anchoring piece and former anchoring piece etc.
Claims (4)
1. meet a root division anchoring piece, it is characterized in that: on a connecting body, be connected with two or more chemical anchor bolts or expansion anchor, connecting body itself can have tapped hole, or direct and other anchoring pieces welding.
2. root division anchoring piece according to claim 1, is characterized in that: described connecting body is Cylindrical object, can have tapped hole or directly weld external piece on it.
3. root division anchoring piece according to claim 1, is characterized in that: described two or more chemical anchor bolts or expansion anchor, its net sectional area sum is more than or equal to the anchoring piece sectional area of outer company.
4. root division anchoring piece according to claim 1, it is characterized in that: described each chemical anchor bolts or expansion anchor, and the Connecting format between connecting body is a kind of in integral type, assembly type, during for assembly type, for screw-thread fit, through hole coordinate, a kind of in coordinating of taper hole.
