Description

Anchor assembly that increases the fixing force of anchor pipes using threaded threads}

The present invention relates to an anchor assembly, and when a machine or structure is fixed to concrete, an anchor in which the fixing force of the anchor pipe is increased by using a screw thread when connecting an anchor pipe located in an anchor hole and an anchor bolt inserted into the anchor pipe It's about assembly.

First, looking at the prior art,

In general, anchor bolts are a generic name for bolts that connect the base of a steel structure or wooden column, or a structure such as an iron girder of a bridge and the foundation of concrete or reinforced concrete, and are provided in various forms depending on the purpose of use, and these are simply Looking at it, it can be broadly classified into three types, which can be classified into buried type and strong and chemical anchor bolts.

In the case of the buried anchor bolt, the ground is dug to a certain depth and the one end of the bolt is inserted and then concrete is poured and installed, and is mainly used when installing a street lamp post.

The strong anchor bolt is a bolt having a wedge tapered downward and provided above the wedge, the lower end is cut by a certain length, and a male screw is formed at the upper end, which drills a hole in the concrete base to which the anchor bolt is to be installed and drills a hole to a certain depth. When a wedge is inserted into the hole and the upper end of the bolt is hit, the bolt enters the wedge and the incision in the tapered portion of the wedge is widened and fixed in the form of digging into the hole formed, which is the most commonly used.

The chemical anchor bolt is a two-component type, and after forming a hole in the concrete base surface with the adhesive and curing agent stored in the tube, inserting the chemical tube into the hole, and hitting the bolt to float the chemical tube, mixing the adhesive and the curing agent This will fix the bolts by

However, in the case of the conventional strong anchor bolt, after inserting the anchor bolt into the drilled anchor insertion hole, the taper part must be widened by the wedge by striking the bolt. There was a problem with the irregular fixing force of the anchor bolt that the uniform fixing force could not be provided as the striking strength of the bolts acted differently depending on the working time.

In addition, in order to compensate for the above problems, there is a problem in that workability is reduced due to a secondary problem that the anchor bolt may be damaged if the anchor bolt is forcibly struck.

In addition, in the case of the chemical anchor bolt, there is an advantage that a constant strength can be maintained compared to the strong anchor bolt, but there is a problem in that the working time is increased because the strength cannot be maintained while the chemical liquid is hardened.

The present invention has been devised to solve the problems of the prior art, and by using an anchor bolt inserted into the inner space of the anchor pipe by configuring one or more plurality of incisions in the lower part of the anchor pipe located in the anchor hole. When the user rotates the anchor bolt using the bolt thread formed on the outer periphery of the anchor bolt and the thread formed on the inner periphery of the anchor pipe, the bolt thread and the screw thread are engaged, so that the cutout formed on the lower part of the anchor pipe is extended outward and the expanded part This was completed as a technical task with an emphasis on providing an anchor assembly that can be fixed to the anchor hole and can increase the anchoring force of the anchor pipe by additionally using a silicone capsule depending on the use.

Therefore, the present invention is inserted and installed in the anchor hole formed in the concrete to fix the machine or structure to the concrete. A rotating member for rotating the bolt, a bolt screw thread is formed on the outer periphery of the lower part, an inner space inside the anchor pipe, a screw thread corresponding to the bolt screw thread on the lower inner side, and one or more incisions in the longitudinal direction at the lower part The technical feature of the anchor assembly is to increase the fixing force of the anchor pipe using a screw thread, characterized in that the part is formed.

According to the anchor assembly of the present invention, which increases the fixing force of the anchor pipe using the screw thread, the cutout formed at the lower part of the anchor pipe is expanded outward by the rotation of the anchor bolt, and the expanded portion is fixed to the anchor hole, and the It is an invention with a great effect, such as being able to increase the fixing force for the anchor pipe and anchor bolt by placing the silicone capsule at the bottom.
