Description

Anchoring member

Technical Field

The utility model relates to an anchor connects technical field, concretely relates to anchor component.

Background

The anchoring connection is a connecting component for fixedly mounting one object on another object, and generally comprises a chemical anchor bolt and a mechanical anchor bolt, wherein the chemical anchor bolt is used for quickly and fixedly mounting a connecting piece by using a chemical agent, but the chemical anchor bolt has the phenomena of long curing time and poor curing effect at a lower temperature (for example, lower than-40 ℃) so as to cause unstable connection; the mechanical anchor bolt has good connection strength, but the connection relationship is dismantled, the built-in connecting piece is not easy to take out, and the connecting piece needs to be kept in a hole, so that the hole cannot be reused.

Disclosure of Invention

The utility model aims at providing an anchor component, this ladder anchor component simple structure is compact, connects stably, and convenient to detach takes out, and the practicality is stronger.

In order to achieve the purpose, the utility model adopts the following technical proposal:

an anchor member comprising an expansion sleeve and an anchor rod, the expansion sleeve being a hollow tubular structure made of an elastomeric material having an opening at one end; the anchor bolt rod is stepped shaft shape, and integration is equipped with first threaded connection portion and second threaded connection portion on the anchor bolt rod, is equipped with extrusion portion and Shi Ning portion respectively at anchor bolt rod both ends, and in screwing up the portion with first threaded connection portion precession inflation sleeve, make the inflation sleeve inflation realize the anchor and connect through exerting.

Preferably, the expansion sleeve is made of vinyl resin through pouring and curing.

Preferably, the inner diameter of the expansion sleeve is smaller than the outer diameter of the first threaded connection part.

Preferably, a plurality of through holes are formed in the side wall of the expansion casing.

Preferably, the Shi Ning portion is a rectangular protrusion disposed outside the end portion of the anchor rod, and the outer contour dimension of the rectangular protrusion is smaller than the inner diameter of the second threaded connection portion.

Preferably, the Shi Ning part is a hexagon socket recess disposed inside the end of the anchor rod.

The utility model discloses in, connect between the first threaded connection portion that the crab-bolt pole set up and install in the threaded hole on timber, metal material etc. under the condition that does not cooperate to use expansion sleeve, can carry out fixed connection to article alone through second threaded connection portion. When the expansion sleeve is required to be fixedly installed in a cement wall body, a brick wall or an irregular through hole, the expansion sleeve is plugged into the through hole, the anchor bolt rod is screwed into the expansion sleeve, the expansion sleeve expands to realize anchoring connection, and then the objects can be separately and fixedly connected through the second threaded connecting part. The arranged screwing part is convenient for fixing and disassembling the anchor bolt rod.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

an anchoring member as shown in fig. 1 and 2 comprises an expansion sleeve 1 and an anchor rod 2, wherein the expansion sleeve 1 is a hollow tubular structure made of an elastic material and provided with an opening at one end, and in one embodiment, the expansion sleeve 1 is made of vinyl resin through pouring and curing, and specifically can be made by mixing vinyl resin 901, quartz particles, cured particles and promoting particles.

Anchor bolt pole 2 is the step shaft form on the whole, and the integration is equipped with first threaded connection portion 3 and second threaded connection portion 4 on anchor bolt pole 2, and the integration sets up extrusion portion 5 on the tip that anchor bolt pole 2 was equipped with 3 one ends of first threaded connection portion, and this extrusion portion 5 is "one" or "ten" word form, and it can drill the material softer relatively of material, and the hole that drills is used for with 3 fixed connection of first threaded connection portion. An screwing part 6 is integrally arranged at one end part of the anchor bolt rod 2, which is provided with the second threaded connection part 4, in one embodiment, the screwing part 6 is a rectangular bulge arranged at the outer side of the end part of the anchor bolt rod 2, and the outer contour dimension of the rectangular bulge is smaller than the inner diameter of the second threaded connection part 4, so that the threaded fixing installation of the second threaded connection part 4 is not influenced. In another embodiment, the applicator 6 is an internal hexagonal recess provided inside the end of the bolt shank 2, which can be rotationally adjusted using an internal hexagonal wrench.

The internal diameter size of expansion sleeve 1 is less than the external diameter size of first threaded connection portion 3, and after filling in expansion sleeve 1 in the downthehole that has opened, rethread portion 6 of screwing in is in expansion sleeve 1 with first threaded connection portion 3, makes expansion sleeve 1 inflation realize the anchor and connects, then fixes the article on second threaded connection portion 4 through the nut. In a preferred embodiment, the expansion casing 1 is provided with a plurality of through holes 7 in its side wall, which through holes 7 increase the expansion effect.

One way of use is to use the anchor rod 2 alone, to fix the first threaded connection 3 to the existing threaded hole, and then to fix the object to the second threaded connection 4 by means of a nut. The other use mode is that the expansion sleeve 1 and the anchor bolt rod 2 are matched for use, firstly the expansion sleeve 1 is plugged into the opened hole, and then the anchor bolt rod 2 is plugged into the expansion sleeve 1 to enable the expansion sleeve 1 to expand to realize anchoring connection. In a more preferred embodiment, the vinyl 901, the quartz particles, the solidified particles and the liquid for promoting the mixing of the particles are injected into the opened hole or the hole of the expansion sleeve 1, then the expansion sleeve 1 is inserted into the hole, the anchor rod 2 is inserted into the expansion sleeve 1, and the injected liquid is used for rapidly solidifying the anchor rod 2 and the wall body through the through hole 7, so that the connection strength and the tensile strength can be further improved.

The above embodiments are only a few descriptions of the concept and implementation of the present invention, and are not intended to limit the scope of the present invention.
