Description
Technical field
The utility model relates to a kind of crab-bolt, particularly relates to a kind of combined type expansion anchor.
Background technology
Intumescent crab-bolt utilizes expansion piece extruding anchor hole hole wall to form the crab-bolt of anchorage effect.It is to utilize centrum and expansion piece
Move towards, promote expansion piece to expand, produce swelling agent pressure with hole wall concrete, and produce anti-by shearing friction effect
Pull out force realizes a kind of assembly to connected piece anchoring.Conventional expanded crab-bolt has following deficiency, and the first, expansion piece expands after-opening
End is inside, anticreep effect difference；2nd, can only be used alone, it is impossible to be used in combination, range is little；3rd, after installing, outward
A termination can be exposed by portion, affects overall appearance.4th, each expansion anchor only one of which expansion piece, withdrawal resistance is little.
Content of the invention
The purpose of this utility model is to provide a kind of resistance to plucking great efforts, and range is wide, it is simple to the combined type of installation expands
Crab-bolt.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of combined type expansion anchor, is made up of expansion tube, connector and conical plug, expansion tube during use, connector and
Conical plug is sequentially connected with and is integrated, and wherein, described expansion tube and conical plug are provided with one, and connector is at least provided with one.
The external diameter of described expansion tube is consistent with the external diameter of connector, and the bar shaped being provided with symmetry at the rear portion of expansion tube is opened
Mouthful, make expansion tube upper flat be divided into two parts of symmetry, expansion effect is good.
Described connector is made up of termination, bullet, cylindrical body and bulge from front to back successively, and described termination is cylinder
Shape, the diameter of termination is consistent with the internal diameter of expansion tube, can increase the contact area of connector and expansion tube, have again guiding
Effect.The diameter of described bullet front end is less than the internal diameter of expansion tube, and the diameter of bullet rear end is more than the internal diameter of expansion tube.Institute
The diameter stating cylindrical body is consistent with the external diameter of expansion tube.The shape of described bulge, size are consistent with expansion tube, Ji Nengyu
Conical plug is connected, and can be connected with connector again.
The beneficial effects of the utility model are: rational in infrastructure, resistance to plucking great efforts, good anti-drop effect, can be solid by multilayer object
It is scheduled on together.Can be used alone, also can be used in combination, applied widely.Hammering is only needed to knock in, construction party
Just, fast, economical, safety.
Brief description:
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
In figure: 1 expansion tube, 2 connectors, 21 terminations, 22 bullets, 23 cylindrical body, 24 bulges, 3 conical plugs.
Detailed description of the invention:
Embodiment 1
It as it is shown in figure 1, a kind of combined type expansion anchor, is made up of expansion tube (1), connector (2) and conical plug (3), makes
Used time, expansion tube (1), connector (2) and conical plug (3) are sequentially connected with and are integrated.The external diameter of expansion tube (1) and connector (2)
External diameter consistent, be provided with at the rear portion of expansion tube (1) symmetry strip gab, make expansion tube (1) upper flat be divided into symmetry
Two parts, expansion effect is good.Connector (2) is from front to back successively by termination (21), bullet (22), cylindrical body (23) and expansion
Portion (24) forms, and termination (21) are cylinder, and the diameter of termination (21) is consistent with the internal diameter of expansion tube (1), can increase even
Junctor (2) and the contact area of expansion tube (1), have again guide effect.The diameter of bullet (22) front end is less than expansion tube (1)
Internal diameter, the diameter of bullet (22) rear end is more than the internal diameter of expansion tube (1).The diameter of cylindrical body (23) and expansion tube (1)
External diameter is consistent.The shape of bulge (24), size are consistent with expansion tube (1), are connected with conical plug (3).
Embodiment 2
It as in figure 2 it is shown, a kind of combined type expansion anchor, is made up of expansion tube (1), connector (2) and conical plug (3), makes
Used time, expansion tube (1), connector (2) and conical plug (3) be sequentially connected with and be integrated, wherein, and described expansion tube (1) and conical plug
(3) being provided with one, connector (2) is at least provided with two.The external diameter of expansion tube (1) is consistent with the external diameter of connector (2), swollen
The rear portion of tube expansion (1) is provided with the strip gab of symmetry, makes expansion tube (1) upper flat be divided into two parts of symmetry, and expansion effect is good.
Connector (2) is made up of termination (21), bullet (22), cylindrical body (23) and bulge (24) from front to back successively, described end
Head (21) is cylinder, and the diameter of termination (21) is consistent with the internal diameter of expansion tube (1), can increase connector (2) and expand
The contact area of pipe (1), has again guide effect.The diameter of described bullet (22) front end is less than the internal diameter of expansion tube (1), cone
The diameter of body (22) rear end is more than the internal diameter of expansion tube (1).The external diameter phase of the diameter of described cylindrical body (23) and expansion tube (1)
Unanimously.The shape of described bulge (24), size are consistent with expansion tube (1), after being connected with another connector (2) again with
Conical plug (3) is connected.Multilayer dose bigger for thickness can be fixed together.
Concrete operations are as follows: first select an alloy bit identical with expansion tube (1) external diameter, be arranged on electric drill
Punching, the degree of depth in hole is preferably identical with the length of combined type expansion anchor, then expansion tube (1) and connector (2)
After being intended to install, one removes in hole, pounds with a hammer, and makes connector (2) fully enter, then takes a conical plug (3), is knocked in by hammer
?.If needing to expose one section to be easy to be connected with other connector, during punching, the degree of depth in hole can according to actual needs and
Fixed, can deeply can be shallow, all can use combined type expansion anchor.
