Abstract
The utility model discloses an expansion bolt specially used in the hollow brick wall which comprises a screw stem with a cuneiform head, a sleeve connected with the screw stem and equipped with an expansion dent, a flat pad, a spring pad and a nut, and is characterized in that the end of the screw stem has a chucking head in coordination with a spanner; the outside of the sleeve is provided with a screw thread, a flat pad and a spring pad, the nut is in succession coordinated with the sleeve. The utility model has the advantages that as the end of the screw stem is provided with a chucking head coordinating with the spanner, when the expansion bolt cuneiform head arranged on the hollow brick wall hole is suspended and the screw stem is hard to be fixed, a spanner is used to chuck the chucking head at the end of the screw stem and another spanner is used to rotate the nut on the screw stem. Thus the nut can be conveniently used to enable the sleeve to move towards the cuneiform head and the cuneiform head is used to enable the expansion dent of the sleeve to expand and fix with the installation on the wall. Then the internal nut on the sleeve is screwed down and then is fixed by the sleeve and the external nut of the sleeve. The bolt has the advantages of simple structure and convenient use.
Description
Technical field
The utility model and a kind of EXPANSION ANCHOR BOLTS more particularly relate to a kind of hollow brick wall dedicated expansion screw bolt, belong to a kind of improvement of EXPANSION ANCHOR BOLTS.
Background technique
Traditional expansion bolt is normally by the screw rod that has sphenocephaly and be enclosed within the sleeve, plain cushion, spring pad and the nut that have the expansion gap on the screw rod and constitute.This EXPANSION ANCHOR BOLTS has join strength height, characteristics easy to use.When after getting out mounting hole on the metope, place mounting hole with iron hammer EXPANSION ANCHOR BOLTS to be squeezed in the mounting hole again the sphenocephaly of EXPANSION ANCHOR BOLTS.At this moment, screw rod is fixed by sphenocephaly and mounting hole, use the spanner swivel nut again, nut is passed sleeve on the sphenocephaly of screw rod, under the effect of screw rod sphenocephaly, the expansion gap end of sleeve increases the installation hole wall swelling on thick and the body of wall, EXPANSION ANCHOR BOLTS is fixed on the body of wall firmly, thereby is used for fixing hanger.But this EXPANSION ANCHOR BOLTS can't be used on the body of wall that hollow brick is made.Because hollow brick is generally the lightweight brick of " day " font.Throw the mounting hole of body of wall into when EXPANSION ANCHOR BOLTS after, the sphenocephaly of screw rod is suspended from the inner chamber of lightweight brick of " day " font, can't be fixing by the hollow lumen chucking of sphenocephaly and body of wall.Because screw rod can't be fixed, therefore can't promote sleeve by nut shifts to sphenocephaly, and sleeve can't increase the installation hole wall swelling on thick and the body of wall, to hollow brick wall EXPANSION ANCHOR BOLTS is installed and has brought inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of hollow brick wall dedicated expansion screw bolt, and it not only can be fixed with the mounting hole on the solid wall, but also can be easily with hollow brick wall on mounting hole fix.
The purpose of this utility model is this realization, and it comprises the screw rod that has sphenocephaly, has sleeve, plain cushion, spring pad and the nut of expansion gap with the screw rod socket, it is characterized in that the end of described screw rod has the dop that cooperates with wrench; The outside of sleeve is provided with screw thread, and plain cushion, spring pad, nut cooperate with sleeve successively.
The utility model has the advantages that, because the end of screw rod has the dop that cooperates with wrench, when the EXPANSION ANCHOR BOLTS sphenocephaly that places the hollow brick porthole unsettled, screw rod is fixedly the time, block the dop of screw rod end with a spanner, use the nut on the another spanner rotary screw again, at this moment just can by nut sleeve be moved to sphenocephaly easily, make the expansion gap distending and the fixing inner nut of tightening again on the sleeve of the mounting hole on the body of wall of sleeve again by sphenocephaly, after the outer nut on sleeve and the sleeve will hang object and fix, have simple in structure, characteristics easy to use are a kind of novelty and the EXPANSION ANCHOR BOLTS product that shows unique characteristics.
Description of drawings
Below in conjunction with drawings and Examples this reality is done novel being described in further detail.
Fig. 1 is a concrete structure schematic representation of the present utility model.
Embodiment
In Fig. 1, there is the sphenocephaly of band angle screw rod 1 upper end of EXPANSION ANCHOR BOLTS, and the end of screw rod 1 is useful on the dop 8 that cooperates with spanner, and the dop 8 of screw rod 1 end is the plane or the square spigot of two symmetries.Sleeve 3 usefulness metal tubes are made, and the wall thickness of sleeve 3 is 2mm, and there are four axial equally distributed expansion gap 2 at left end 1/3 place of sleeve 3, Full Thread FT 4 is arranged on the sleeve 3, or at the right-hand member of sleeve 3 part screw thread 4 is arranged, sleeve 3 and screw rod 1 socket.On sleeve 3, also be with plain cushion 6, spring pad 7 and outer nut 11 or the inner nut 5 that has been threaded respectively.On screw rod 1, be with plain cushion 10 and nut 9 or be with spring pad equally.
During installation, boring at first on the wall has after getting into certain depth when boring saturating sensation, has promptly got on the brick cavity wall.EXPANSION ANCHOR BOLTS is squeezed in the hole with iron hammer by sphenocephaly, and screw rod 1 still is in loosening state.At this moment, screw rod 1 is fixing with spanner by the dop 8 of screw rod 1 end, turn nut 9 on the screw rod 1 with another spanner again, sleeve 3 is moved to left, the sphenocephaly of sleeve 3 by screw rod 1 termination makes the expansion gap 2 distending chaps on the sleeve 3, tightens inner nut 5 again and just EXPANSION ANCHOR BOLTS can be fixed on the body of wall firmly.At this moment, can method routinely be installed by hanging object.
Claims (3)
1, a kind of hollow brick wall dedicated expansion screw bolt, it comprises the screw rod that has sphenocephaly, has sleeve, plain cushion, spring pad and the nut of expansion gap with the screw rod socket, it is characterized in that the end of described screw rod has the dop that cooperates with wrench; The outside of sleeve is provided with screw thread, and plain cushion, spring pad, nut cooperate with sleeve successively.
2, hollow brick wall dedicated expansion screw bolt according to claim 1 is characterized in that the thick 2mm of barrel of described sleeve.
