Abstract
The invention provides a casing pipe. The casing pipe comprises a pipe body (1). Secondary holes are formed in one end of the pipe body (1), the hole close to the outside is the hexagonal hole (2), the hexagonal hole (2) is matched with hexagon nuts of expansion bolts of various specifications, the hole close to the inside is the circular-truncated-cone-shaped hole (3), and the circular-truncated-cone-shaped hole (3) is matched with the outer ends of threads of the expansion bolts of various specifications. A circular hole (4) is formed in the other end of the pipe body (1), two grooves are symmetrically formed in the wall of the circular hole (4), the circular hole (4) is matched with a percussion drill or a drill bit rod of an electric hammer, and the two grooves are matched with two convex edges of alloy steel of a drill bit. The casing pipe can fix the advancing direction of the expansion bolts, protect the outer ends of the threads, and guide impact force of the electric hammer, under the protection of the casing pipe and with the help of the impact force of the electric hammer and linearity and vibratility of the impact force of the electric hammer, the advancing speed of the expansion bolts after the expansion bolts are drilled into wall holes is high, working efficiency is improved, the expansion bolts are intact and free of being wasted, and labor intensity is relieved.
Description
Technical field
The present invention relates to a kind of sleeve pipe that construction engineering is used, is the assistant tool of the EXPANSION ANCHOR BOLTS of indoor and outdoor decoration and installing engineering use.
Background technique
EXPANSION ANCHOR BOLTS is widely used in construction engineering, particularly various indoor and outdoor decorations and installing engineering.But the method that existing EXPANSION ANCHOR BOLTS is thrown in wall column hole is all manually to hold iron hammer directly to impact, and the EXPANSION ANCHOR BOLTS overwhelming majority is all used in concrete structure hard wall column, powder and hole wall resistance that boring stays are very large.The process of moving in staff due to iron hammer forms certain arc dynamics direction, so bolt thread outer end is impacted the stressed direction in position and bolt is inconsistent along the direction of advancing in hole, is partial to certain on one side, can cause bolt cannot throw in hole; Thread outer end is impacted position gross distortion, and nut cannot be backed out, and all these cause EXPANSION ANCHOR BOLTS to use, and cause huge waste.Returning the wall cylindrical surface of being constructed causes severe trauma impact attractive in appearance.The hammering of workman's grip rail is beaten, and labor intensity is quite large, at the bottom of working efficiency, has serious potential safety hazard during high-lift operation.
Summary of the invention
The object of this invention is to provide a kind of sleeve pipe, by this sleeve pipe, can be better EXPANSION ANCHOR BOLTS be driven into needed position, improved the utilization ratio of EXPANSION ANCHOR BOLTS, increase work efficiency.
A kind of sleeve pipe of the present invention, it is characterized in that it comprises body, one end at body has second hole, hole is outside hexagonal hole, the hexagon nut of the EXPANSION ANCHOR BOLTS of hexagonal hole and all size matches, hole is inside frustoconic shape hole, and the thread outer end of the EXPANSION ANCHOR BOLTS of frustoconic shape hole and all size matches; The other end at body has circular hole, in the hole wall symmetry of circular hole, has two grooves, and the drill bit shaft of circular hole and percussion drill or electric hammer matches, and two grooves of circular hole hole wall and alloyed steel two chimbs of drill bit match.
The hexagonal hole that sleeve pipe of the present invention one end is offered and round platform hole are to set according to the specification of EXPANSION ANCHOR BOLTS, EXPANSION ANCHOR BOLTS specification has 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, the size of the circular hole of the sleeve pipe the other end is to set according to the drill bit shaft size of percussion drill used or electric hammer, matching with drill bit shaft.
During normal use, put EXPANSION ANCHOR BOLTS nut into second hole, hexagon nut is in the position of hexagonal hole, and thread outer end is in the position in frustoconic shape hole.The circular hole of the sleeve pipe the other end is set in the drill bit shaft of percussion drill or electric hammer and can uses.
Use sleeve pipe of the present invention, solved that in prior art, EXPANSION ANCHOR BOLTS to be squeezed into the striking speed existing in porthole slow, EXPANSION ANCHOR BOLTS is yielding, not only wasted material but also affect attractive in appearance, inefficiency, the large shortcoming of labor intensity.Sleeve pipe of the present invention plays fixed expansion bolt direction of advance; the effect of protection thread outer end and guiding electric hammer impact force; under the protection of sleeve pipe; by electric hammer impact force; with linarity and the vibratility of electric hammer impact force, it is fast that EXPANSION ANCHOR BOLTS is squeezed into the speed that porthole advances, and increases work efficiency; EXPANSION ANCHOR BOLTS is excellent does not cause waste, reduces labor intensity.
Accompanying drawing explanation
Fig. 1 is the whole generalized section of sleeve pipe of the present invention;
Fig. 2 is the sectional view that the body of sleeve pipe of the present invention is offered circular hole end;
Fig. 3 is the sectional view that the body of sleeve pipe of the present invention is offered Hexagon nose end.
In figure 1 is body, the 2nd, and hexagonal hole, the 3rd, frustoconic shape hole, the 4th, circular hole.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the mode of execution of sleeve pipe of the present invention:
A kind of sleeve pipe of the present invention, comprise body 1, one end at body 1 has second hole, hole is outside hexagonal hole 2, hexagonal hole 2 matches with the hexagon nut of the EXPANSION ANCHOR BOLTS of all size, hole is inside frustoconic shape hole 3, and frustoconic shape hole 3 matches with the thread outer end of the EXPANSION ANCHOR BOLTS of all size; The other end at body 1 has circular hole 4, in the hole wall symmetry of circular hole 4, opens two grooves, and circular hole 4 matches with the drill bit shaft of percussion drill or electric hammer, and alloyed steel two chimbs of two grooves and drill bit match.
During use, first the nut screwing clamping of EXPANSION ANCHOR BOLTS is caused to screw rod roughly suitable with nut thickness through nut and the length of passing, then it is packed in the second hole of sleeve pipe, hexagon nut and hexagonal hole 2 match, and the screw rod that passes nut is just enclosed within round platform hole 3.Then electric hammer gear is chosen in to electric hammer position, then grip has the circular hole of sleeve pipe of the present invention one end of EXPANSION ANCHOR BOLTS to pack into electric hammer drill, two grooves that two projections of drill bit alloyed steel are aimed at hole walls can pack into.Hold the sleeve pipe that is inserted in EXPANSION ANCHOR BOLTS and drill bit on the other hand, another holds electric hammer, EXPANSION ANCHOR BOLTS end is aimed to the eyelet having bored in advance, pulls electric hammer switch, and along perforate direction, by electric hammer impact force, moment is thrown wall column hole into bolt.The present invention plays fixed expansion bolt direction of advance, the effect of protection thread outer end and guiding electric hammer impact force.
