Description

Assembly object assembly structure using multi-functional anchor for assembly object assembly }

The present invention relates to an assembly structure for an assembly object using a multifunctional anchor for assembling an assembly object, and more particularly, for assembling first and second objects to be assembled, an anchor interposed therebetween is inserted into a guide insertion hole of the second assembly object. The present invention relates to an assembly structure for an assembly object using a multifunctional anchor for assembling an assembly object, which provides a guide unit to facilitate assembly between the two.

In general, in the case of prefabricated assembly objects such as wooden furniture, anchors are mainly used to facilitate assembly and disassembly, prevent damage such as splitting of wood in the process of fastening fasteners, and maintain good bonding strength. .

As an example, schematically looking at the anchor of the prior art, a through hole is formed so that an assembly bolt is inserted into the inside and screwed, and at the tip of the through hole, a plurality of projections protrude on the outer periphery by tightening the assembly bolt. It consists of a structure in which the incision part is opened so that the clamping piece can be strongly compressed on the inner wall of the assembly hole, and such a conventional anchor has no means to penetrate the assembly object by itself, so in order to use the anchor, the anchor is first inserted into the assembly object A hole to be drilled is first drilled, an anchor is inserted into the hole, and then an assembly bolt is assembled.

However, as described above, in the case of drilling a hole in advance, the anchor can be inserted only when the hole is drilled larger than the diameter of the anchor. As a result, even if the diameter of the tip of the anchor is expanded by assembling with assembly bolts, the size of the hooking piece inserted into the object to be assembled When is small, the bonding force with the assembly object is weak, and when the coupling force is weakened in this way, when applied to an assembly object made of the assembly object or a door, a gap occurs in the coupling part, causing problems such as sagging of the door or creaking of the assembly object. It became.

In addition, when the hole is drilled smaller than the diameter of the anchor, it is impossible to insert the anchor, so a new hole must be drilled, which makes the work cumbersome.

In order to solve this problem of the prior art, in another prior art, a drill blade and a sharp screw thread are formed so that the anchor body penetrates the assembly object and is firmly fixed, so that a separate hole drilling operation is not required during assembly. An anchor that facilitates the fastening process is presented.

In the anchor assembly structure through the anchor of the prior art, a fastening groove with a threaded portion in the center is formed in the axial direction, a sharp thread is formed on the outer periphery, a drill blade is formed on the outer circumference of the tip formed in a conical shape, and the tip is tensioned A multifunctional anchor body formed with a cutout in the axial direction to have; It is composed of a coupling assembly bolt screwed into the multifunctional anchor body, so that the anchor body directly penetrates the assembly object and is tightly fixed.

However, the anchors of the related art guide the fastening hole of the subsequent assembly object to the fastening hole of the preceding assembly object during the assembly work between the assembly objects, or the guide for supporting the assembly object in a state where the fastening holes between each other are placed on the same line. And since no support means is provided at all, it is basically difficult to match the fastening holes between the assembly objects, and even when assembling each other, the assembly work must be performed while the operator holds and supports the assembly objects with his hands. There were problems such as discomfort.
