Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is for fixing a composite material by stacking stones or porcelain plates on the surface of stones, tiles, gypsum boards, etc. (hereinafter collectively referred to as stones, etc.) Regarding the fastener.

[0002]

[Prior art]

 Recently, when a stone or the like is attached to a building, a dry construction method is widely used in which a mortar is not applied and a stopper is used. Most commonly used fasteners are composed of a skeleton-side metal fitting that is attached to the building skeleton side and a stone-side metal fitting that can be connected to this skeleton-side metal fitting and that is attached to the stone material side.

[0003]

[Problems to be solved by the device]

 In the above-mentioned stopper, since the work for connecting the two metal fittings is performed between the stone material and the building frame, it is necessary to secure a work space for reaching between them. Therefore, with the conventional stopper, a gap is created between the stone material and the attached object. Such a gap may be unfavorable in terms of design. For example, in a design in which a smaller porcelain plate is stacked on a porcelain plate, the stacked porcelain plates are lifted, which seriously affects the appearance. In addition, such a gap is also inconvenient when there are dimensional restrictions in the thickness direction. In addition to this, a metal fitting to be attached to a stone material, etc. must secure sufficient attachment force to the stone material.

The present invention has been made in view of the above circumstances, and eliminates a gap between a stone or the like and an object to be attached, which improves the degree of freedom in design and design, and reliably engages the stone or the like. The purpose is to provide a wearable stop.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the structure of the present invention is a stopper for fixing a stone or the like to an object to be mounted, and a pair of split metal fittings that can be engaged with the stone or the like in a state of facing each other. , Clamping means having a connecting portion for connecting both split metal fittings and a screw shaft portion protruding into a through hole penetrating the attached object, and screwing the screw shaft portion to the attached object. Each of the above-mentioned split metal fittings is composed of a fitting piece that comes into close contact with the surface facing the object to be mounted and a side edge of the fitting piece that is opposite to the dividing edge, and is parallel to the stone material. Formed of a locking leg piece engageable with a pair of fitting grooves engraved in a circular shape, and a connecting piece that is erected so as to be opposed to the division edge side of the contact piece and that projects into the through hole. The connecting portion of the clamp means has a connecting portion that penetrates the connecting portions facing each other. An inclined surface is formed that is inserted into the hole and engages with both connecting holes so as to act in a direction in which the split metal fittings are pulled toward each other as the screw shaft portion and the fixture are tightened. It is what

[0006]

[Action]

 While engaging the locking leg pieces of both split fittings with the fitting groove, these connecting pieces face each other. Then, the connecting portion of the clamp means is inserted into both connecting holes of the connecting piece, and the inclined surfaces are engaged with both connecting holes. Next, in order to attach the stone or the like to the object to be attached, the stone or the like is brought into close contact with the object to be attached, and the connecting piece and the screw shaft portion are projected into the through hole. In this state, screw the fixture into the screw shaft. With this tightening operation, the connecting portion is pulled up to the fixing tool side. By this pulling up operation, both connecting pieces are drawn while being guided by the inclined surface. As a result, the locking leg pieces of both split fittings bite into the fitting groove, and the mounting fitting is fixed to the stone material or the like.

[0007]

[Effect of device]

 The effects of the present invention are as follows. Since the object to be attached is provided with a through hole and the fixing work is performed through the hole, the stone material and the object to be attached can be in close contact with each other. Therefore, unlike the conventional case, it is not necessary to secure a working gap between the stone or the like and the object to be attached, and the degree of freedom in design can be increased. Further, since the mounting metal fitting is divided, the leg piece can be easily locked even if it is shaped like an undercut, which easily prevents the fitting groove from coming off. Moreover, since the two split metal pieces are made to bite into the stone or the like by utilizing the inclined surface, the stopper can be strongly fixed to the stone or the like.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 3 show a first embodiment of the present invention. As shown in FIG. 1, mounting portions 11 for mounting the mounting bracket 2 are arranged at four corners of the surface of the stone material 1 facing the building frame 3 (attached object). A pair of fitting grooves 12 are provided in parallel at a predetermined interval in the mounting portion 11, and a base 11a slightly recessed from the surrounding surface is formed between them (specifically, the mounting bracket 2). Of the thickness of the). Both fitting grooves 12 have an undercut shape that inclines inwardly toward the bottom of the grooves.

The mounting bracket 2 is composed of a pair of vertically divided split brackets 13, each of which has a contact piece 13a that is in close contact with the base 11a, and the fitting groove 12 of the mounting section 11 and the fitting groove 12 at the edge thereof. A locking leg piece 14 is provided which is bent inwardly with substantially the same inclination. A connecting piece 16 is erected on each of the split fittings 13 so as to face the central portion of the split edge. Further, in this embodiment, a temporary fastening ring 17 is fitted on both connecting pieces 16 to draw the split metal fittings 13 together so that the mounting metal fitting 2 cannot be easily removed. The temporary fixing ring 17 is wound by a wire material so that it can be expanded and contracted in the radial direction. In addition, locking recesses 18 are formed on both lower side surfaces of each connecting piece 16 for hooking the temporary fixing ring 17.

Further, a circular connecting hole 20 is provided at a corresponding position of both connecting pieces 16, and a hook member 21 forming a connecting portion of the clamp means 19 can be inserted therethrough. The hook member 21 has a substantially W-shape as a whole, and a straight portion 25 is formed in a central portion thereof so as to be loosely inserted into a hook mounting hole 23 of a screw rod 22 which will be described later, and both ends thereof are bent at substantially right angles. After being bent, the inclined surface 24 is formed by being bent obliquely upward at an approximately equal angle. This inclined surface 24 can be locked to the upper edge side of the connecting hole 20 of both connecting pieces 16, and as will be described later, when the hook member 21 is pulled up together with the screw rod 22 by tightening the nut 29, the inclined surface 24 follows the slope thereof. It plays a role of pulling both split fittings 13 by slidingly contacting the edge of the connecting hole 20 (see FIGS. 2 and 3).

Further, the threaded rod 22 is formed to have a length that allows it to project to the back side of the body 3 during construction, and a nut 29 is screwed into this projecting portion through a mounting washer 28 having a larger diameter than the through hole 27. Are combined.

Next, the operation of the first embodiment will be described. The connecting pieces 16 are opposed to each other in a state in which the contacting pieces 13a are brought into close contact with the base 11a while the locking leg pieces 14 of the two split fittings 13 are locked in the corresponding fitting grooves 12. Since the base 11a is slightly recessed from the surroundings as described above, the contact piece 13a is substantially flush with the back surface of the stone material 1 or the like. However, when the adhesion between the stone material 1 and the building frame 3 is not strictly required, the base 11a may be a flat surface flush with the surroundings.

Next, the hook member 21 is attached to the screw rod 22 to integrate the clamping means in advance, and the both inclined surfaces 24 are fitted into the connecting holes 20 to loosen the clamping means 19 and the split metal fittings 13. Engage. After that, when the temporary fixing ring 17 is attached around the both connecting pieces 16 while expanding the diameter and is locked in the locking concave portion 18, the split fitting 13 is temporarily fixed to the mounting portion 11 by the tightening force of the temporary fixing ring 17. It is kept stopped. The above-described operation is repeated for each mounting portion 11, and the mounting metal fitting 2 is preliminarily attached to each corner of the stone material 1 in the temporarily fixed state.

After that, the stone material 1 is brought into close contact with the building frame 3 while inserting both the connecting pieces 16 and the clamp means 19 into the through hole 27, and the mounting washer 28 is attached to the screw rod 22 projecting to the back side of the frame 3. Tighten the nut 29 via. Then, as shown in FIGS. 2 and 3, the screw rod 22 is fixed to the body 3 as the nut 29 is tightened, and at the same time, the clamp means 19 is pulled toward the rear surface side. By pulling up the inclined surface 24, the connecting piece 16 is pulled inward while the upper edge of the connecting hole 20 is in contact with the inclined surface 24, and the two locking leg pieces 14 bite into the fitting groove 12. As a result, the mounting member 2 is firmly fixed to the stone material 1 and the stone material 1 is fixed to the body 3.

According to the fastener of the first embodiment, it is possible to attach the stone material 1 and the building frame 3 without a gap on the facing surface. Therefore, when the stones 1 and the like 1 are attached by the fasteners, the design restrictions are relaxed, the appearance can be improved, and it is also useful for the construction site where the thickness direction is restricted. Further, since the mounting metal fitting 2 is divided, it can be easily mounted even in the undercut-shaped fitting groove 12 which is advantageous for preventing the slip-out. Since this undercut groove is relatively easy to machine, there is also an advantage that the machining of a stone material 1 is easy. Further, since the inclined surface 24 is provided and the split metal fitting 13 is fixed at the same time as tightening, the work is simple and a strong engaging force with respect to the stone material 1 can be obtained.

FIG. 4 shows a second embodiment of the present invention, and the stopper of the second embodiment shows a modified example of the clamping means. In the clamp means of the first embodiment, the hook member 21 and the screw rod 22 are formed separately, but the clamp means may be one in which the hook member and the screw rod are integrated as in the second embodiment. . The clamp means 19 of the second embodiment is provided with a hook member 33 having two inclined surfaces 32, which are inclined upward, at the lower end of a threaded rod 31 having a threaded portion so as to form an arrow shape. It is the one that was made. The clamp means 19 is attached so that each inclined surface 32 engages with the connecting hole 20 of each split fitting 13 as in the first embodiment. The other structure is the same as that of the first embodiment, and the same effects are shown. Therefore, the description thereof is omitted.

FIG. 5 shows a third embodiment of the present invention, which also shows a modification of the clamp means. The clamping means 19 of the third embodiment is also one in which a screw rod and a hook member are integrally formed, and a hook member 37 bent into a substantially hexagonal shape is formed at the lower end of the screw rod 36 provided with a screw portion. The hook member 37 is integrally provided, and the lower side of the hook member 37 is a V-shaped inclined surface 38. Also in the clamping means 19 of the third embodiment, if the inclined surface 38 is engaged with the connecting hole 20 of each connecting piece 16, the mounting member 2 is made of stone or the like by pulling up the clamping means 19 as in the above-mentioned respective embodiments. It is fixed at 1. The rest of the configuration is the same as that of each of the above-described embodiments, and will not be described because it shows the same action and effect.

The fixing means of the present invention is not limited to the fixing means of each of the above-mentioned embodiments, and any screw shaft rod having an inclined portion on the hook member may be used, and the shape, material, etc. can be changed. Is.

Further, although the stoppers of the above-mentioned respective embodiments are used as the stoppers for attaching the stone material 1 to the building frame 3, the present invention is not limited to this, and the stopper when the stone material or the like is further attached on the stone material or the like. You may use it as an ingredient.

Further, although the connecting hole 20 in each of the above-described embodiments is a round hole, the connecting hole 20 is not limited to this and may be an elliptic connecting hole that is long in the lateral direction.
