Abstract

PURPOSE:To enhance reliability and simplicity in the setting of an anchor to a shallow space and thin setting part by connecting a receiver plate which has a longer side than the diameter of setting hole and a shorter side than that, to a pusher plate so as to maintain a preset clearance with a flexible and deformable connecting part, at respective ends. CONSTITUTION:A receiver plate 3 for setting is set on upside of an anchor and a pusher plate 4 on underside. The shorter side of the receiver plate 3 for setting and one of the longer side of the pusher plate 4 are connected with a flexible and deformable connecter 5. Besides, the receiver plate 3 has a through hole 7, for a fastening part 2, formed in a rectangle shape with one side 3a longer than the diameter of setting hole H of a part W to be set on a wall and another side 3b shorter than that. The pushing plate 4 for setting is arranged vertically with the receiver plate 3 and has a through hole 8, for the fastening part 2, formed at the center in a rectangle with the long side 4a longer than the diameter of setting hole H and the shorter side 4b almost similar to that. Thus, even if the inner space of wall W is hallow or the thickness is thin, reliable and simple setting is assured.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides an anchor for easily and reliably attaching members such as boards to walls or other structures having a hollow portion inside. Regarding improvements.

(Prior Art) As this type of anchor, a wide variety of anchors have been proposed and used in the past, and for example, the following are well known.

Specifically, one method is to directly attach a female thread to the inner peripheral surface of a tube formed at the insertion side tip of a sleeve in a plastic board anchor that is equipped with an expansion slit and a flange on the outer periphery of the base part. The other one is that instead of directly carving a female thread in the above-mentioned pipe part,
A nut-like member with a female thread carved on the inner circumferential surface of a short metal tube is sealed and internally inserted into the tube portion during molding of the board anchor.

(Problem to be Solved by the Invention) However, in any of the above cases, since the expanding member is used as a means for preventing the anchor from falling off, the expanding member has a considerable length before being expanded. I need to be there. Therefore, there is no problem if the hollow part in the facility is deep, but in recent buildings and structures, due to the following requirements, it may be impossible to use conventional anchors with long legs. are becoming more common. In other words, the recent trend is to make the interior space of buildings as wide as possible by making the depth of the hollow part of the anchor construction part as shallow as possible. This is because there is a tendency to reduce weight and save materials by reducing the thickness of the boards, etc. to be attached, and in such cases, conventional anchors cannot be used to attach the boards, etc. This poses a serious problem that makes construction difficult or impossible.

The present invention was researched and developed with the aim of solving the above problems, and even if the hollow part at the point where the anchor is used is shallow, in addition to this, the wall thickness and the board thickness To provide an anchor having an epoch-making feature such that even if it is thin, it can be reliably and easily installed with the anchor without any hindrance.

(Means for solving the problem) In the present invention, as a means for solving the above problem,
An anchor consisting of a combination of an anchor body and a fastening member such as a threaded rod has a width that is longer than the diameter of a mounting hole penetrated through a member to be attached such as a wall, and a diameter that is longer than the diameter. a mounting receiving plate having a short width and having an insertion hole for the fastening member such as the screw rod; and mounting press plates, which are connected at one side with a required spacing by a connecting material having bendable deformability, and are arranged facing each other, and the parts other than the connecting part are left open. We have developed and adopted an anchor characterized by having an anchor body formed with a section.

(Function) Since the claimed invention is configured as described above, it is possible to create a hollow part according to the steps shown in (A), (Ex), (C), (2), and (E) in Figure 6. The board B is attached to the wall surface W, but since it does not include an expansion member that causes an expansion effect like conventional ones, the length of the anchor body can be significantly shortened, and the depth of the hollow part of the wall surface etc. Even if the anchor is shallow, the board can be attached to the wall surface W without any problems.In addition, its unique structure allows for easy installation, and the mounting receiver of the anchor body The plate has a short and medium part that is shorter than the diameter of the mounting hole H provided in the wall surface W, and a long and medium part that is longer than the diameter of the mounting hole H. It has the effect of making it easy to insert the mounting receiving plate, and after installation, together with the bending deformability of the connecting material, it reliably prevents the mounting receiving plate from coming out of the mounting hole. It has an effect.

In general, the shape and size of the mounting press plate of the anchor body are not as important components in this application, and as shown in FIG. Since it is engaged with the mounting receiving plate, even if the size of this push plate is smaller than the mounting hole 1'', there will be almost no problem in mounting. Furthermore, it is preferable for the engagement state between the insertion hole provided in the mounting receiving plate and the fastening member to be in a screwing relationship as shown in FIG. , it may be in the form of press-fit engagement.

(Embodiments) Below, preferred embodiments of the present invention will be described based on the accompanying drawings. 1, 2
Accordingly, the anchor according to the present invention is constructed.

In this embodiment, the anchor body 1 is formed by integrally stamping sheet material by press working, and as is clear from each figure, there is a mounting receiving plate 3 in the upper part toward the figure. is provided, and a mounting push plate 4 is provided at the lower part, and both plates 3,
4 is the short width side of the mounting support plate 3, and one side of the long width side of the mounting push plate 4 is connected through a connecting member 5 having bendable deformability made of the same material as each plate 3, 4. They are connected and disposed opposite each other with a short distance apart, and a portion other than this connecting portion is opened to form an open portion 6.

Further, the mounting receiving plate 3 has a width 38 that is longer than the diameter of the mounting hole H formed through the mounting member W such as a wall surface, and a short width that is shorter than the diameter. 3b, and in this embodiment, an insertion hole 7 consisting of a threaded hole for screwing and tightening the fastening member 2 consisting of a threaded rod is provided approximately in the center.

The mounting press plate 4 is arranged so as to be perpendicular to the receiving plate 3, and has a width 4a longer than the diameter of the mounting hole H, and has a width 4a that is approximately the same as the diameter. Short width 4
It is formed into a rectangular shape with a diameter of 1.b, and has an insertion hole 8 approximately in the center for loosely inserting the fastening member 2. In the figure, 9 is a reinforcing rib, and 10 is a short part of the push plate Each of the bending protrusions provided at the edge on the side opposite to the connecting member 5 on the width 4b side is shown.

Next, to explain the usage condition according to the above embodiment, first, as shown in FIG. Then, as shown in (opening) of the same figure, insert it into the mounting hole H from the short width 3b side of the receiving plate 3, and operate according to the steps shown in (c) and (2) of the same figure. After aligning the bent edge 10 of the push plate 4 and the outer circumference of the connecting member 5 with the inner circumference of the mounting hole H, as shown in (E) of the same figure, attach the board B to the back of the push plate 4.
