Abstract
The utility model discloses an expansion bolt, which structurally comprises a stud and expansion camber members disposed around the stud. The number of the expansion camber members is at least three, one ends of the expansion camber members are fixedly connected to a threadless fixing plug close to a hexagonal stud bolt and sleeved on the stud, and the other ends of the expansion camber members are fixedly connected to a nut in threaded connection with the stud. The expansion camber members are expansion camber steel sheets or expansion camber reinforcing steel bars or expansion camber steel wires. Notches easy to expand outwards are disposed in the middle position of the expansion camber members. Force and amplitude of expansion of the expansion bolt are both larger than those of the existing expansion bolt. The nut is adopted to be welded with the expansion camber steel sheets between the stud and the nut, and two-way pressure generated between the nut and the bolt under the action of external force rotation enables the expansion camber steel sheets to generate expansion force towards outside. The expansion bolt is capable of generating huge expansion force on any wall conditions so that fixing bodies cannot fall off to cause damage and the objective of being firm and durable is achieved.
Description
Technical field
The utility model relates to EXPANSION ANCHOR BOLTS, specifically a kind of EXPANSION ANCHOR BOLTS that is applicable to any body of wall.
Background technique
At present, known EXPANSION ANCHOR BOLTS is the swelling pressure that produced by double-screw bolt and expander iron plate single-point pressure.Its expansion dynamics is very little, must select the body of wall of certain robustness, otherwise does not have the fixing effect of expanding, and hollow or body of wall is aging such as body of wall inside all can cause coming off or the fixing insecure defective such as certain harm that causes of EXPANSION ANCHOR BOLTS.Therefore a kind of ability of necessary design is fit to the EXPANSION ANCHOR BOLTS of multiple body of wall.
Summary of the invention
The purpose of the utility model is the defective that exists to existing technology; A kind of EXPANSION ANCHOR BOLTS is provided; Expansion dynamics and amplitude are all bigger, can be suitable for more body of wall, solve coming off and unstable phenomenon that the existing technology EXPANSION ANCHOR BOLTS is applied to that unsubstantial body of wall causes.
The utility model solves the technological scheme that its technical problem adopted: a kind of EXPANSION ANCHOR BOLTS, its structure comprise double-screw bolt and are arranged on double-screw bolt expansion camber member on every side; Said expansion camber member is at least three, and wherein an end is fastened near double-screw bolt hexagonal double-ended bolt head and is enclosed within no silk on the double-screw bolt fixedly on the blocking piece, and the other end is fastened on rotation set on the nut on the double-screw bolt screw thread.
Said expansion camber member is arc steel disc or expand arc reinforcing bar or the expansion arch wire of expanding.
Said expansion camber member intermediate portion is offered and is easy to the outwards breach of expansion.
A kind of EXPANSION ANCHOR BOLTS of the utility model is compared with existing technology, has following beneficial effect:
The utility model EXPANSION ANCHOR BOLTS expansion dynamics and amplitude are all greater than traditional expansion bolt; Between double-screw bolt and nut, adopt the nut and the arc steel disc welding of expanding, be bolt under the external force turning effort and the bidirection press that produces between nut make arc steel disc produce expansive force laterally.Thereby the utility model can not come off fixed body to work the mischief, reach robust purpose no matter under any body of wall situation, can produce huge expansive force.
Description of drawings
Fig. 1 is the structural representation of a kind of EXPANSION ANCHOR BOLTS of the utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1.
Among the figure: 1, double-screw bolt; 2, there is not fixedly blocking piece of silk; 3, the arc steel disc that expands; 4, nut; 5, breach.
Embodiment
Next explanation at length below with reference to Figure of description a kind of EXPANSION ANCHOR BOLTS of the utility model being done.
As shown in the figure, a kind of EXPANSION ANCHOR BOLTS, its structure comprises double-screw bolt 1 and is arranged on double-screw bolt expansion camber member on every side; Said expansion camber member is at least three.Said expansion camber member is arc steel disc 3 or expand arc reinforcing bar or the expansion arch wire of expanding.According to diagram, present embodiment has adopted three arc steel discs 3 that expand, and generally speaking, adopting three or four is preferred version.A said expansion camber member wherein end is fastened near double-screw bolt hexagonal double-ended bolt head and is enclosed within no silk on the double-screw bolt fixedly on the blocking piece 2, and the other end is fastened on rotation set on the nut on the double-screw bolt screw thread 4.Said expansion camber member intermediate portion is offered and is easy to the outwards breach 5 of expansion.Between double-screw bolt and nut, adopt the nut and the arc steel disc welding of expanding, be bolt under the external force turning effort and the bidirection press that produces between nut make arc steel disc produce expansive force laterally.
The above embodiment is a kind of of the more preferably concrete mode of execution of the utility model, and common variation that those skilled in the art carries out in the utility model technological scheme scope and replacement all should be included in the protection domain of the utility model.
Claims (3)
1. EXPANSION ANCHOR BOLTS is characterized in that: its structure comprises double-screw bolt and is arranged on the expansion camber member around the double-screw bolt; Said expansion camber member is at least three, and wherein an end is fastened near double-screw bolt hexagonal double-ended bolt head and is enclosed within no silk on the double-screw bolt fixedly on the blocking piece, and the other end is fastened on rotation set on the nut on the double-screw bolt screw thread.
2. a kind of EXPANSION ANCHOR BOLTS according to claim 1 is characterized in that: said expansion camber member is arc steel disc or expand arc reinforcing bar or the expansion arch wire of expanding.
