[0001]

[Industrial applications]

 This invention is a joiner for fixing joints between adjacent or multi-directional structural plates.

[0002]

[Prior art]

 Conventional joiners that are generally used for corner joints such as boards and plates often use L-shaped corners, and H-joiners are widely used as pushing members from many directions. However, most of them are bonded and fixed at a right angle, and in many cases they are used as finishing cosmetics, and their strength is questionable. Moreover, there was no joiner that could be applied not only to a simple structural plate but also to a structural plate, such as joining Maruki and joining glass, stone, brick, etc. In particular, in the case of forming a box body such as a rectangular parallelepiped or a polygonal cylinder, joint portions of each surface having an angle other than a right angle are formed at a plurality of peripheral portions. As shown in Fig. 8, a circular cover for covering the corners and each structural plate sandwiching portion are provided at the center position of the circle to enable them to be joined and fixed at an arbitrary angle. There is one that is rotatably joined at a fulcrum.

[0003]

[Problems to be solved by the device]

 However, in such a conventional corner joiner, it is not certain that the circular cover and the sandwiching parts of both structural plate bodies are joined and fixed, and since the shaft screw is used, the number of parts is large, and the structure plate is used in the sandwiching part of the joiner. When inserting a body, it was difficult to properly insert and fix it to the back of the sandwiching part, and a gap was created between the sandwiching structure plate and the sandwiching part, often resulting in lack of airtightness and waterproofness. In addition, since the corner contour line is also adhered to the sandwiched structural plate body, and the corner contour line is made of the same material, designability tends to be emphasized. For this reason, the corners are composed only of circular covers, and the problem is that strength cannot be obtained. In addition, it was impossible to bond multiple structural plates more strongly than in multiple directions.

Further, in joining the plates, since it is weak to use the wood grain in the longitudinal direction, it is often sufficient if the wood grain can be used in the cross grain. However, there was no joiner that could successfully join the side-by-side plates at an arbitrary angle. In consideration of the above problems, the present invention has been made by the inventor as a result of diligent experiments, and it is possible to join any structural plate body at any angle while maintaining strength, and to be used for both the entering corner and the entering corner. , It provides a joiner that can be used as a parallel joiner and has no problem in terms of airtightness and waterproofness.

[0005]

[Means for Solving the Problems]

 The U-shaped cross-section holding part that fits and joins the side parts of the structure plates to be joined adjacent to each other is inverted. The rear space surrounded by the back surface of the arbitrary square groove is filled and fixed with a spacer or an adhesive curable resin to form a polygonal arbitrary body, and the joiner holding portion has a fitting structure. A through hole projection is provided to fix the plate body, and in the groove back space, a dovetail groove, a through hole, and a protrusion are provided on the groove back to prevent deformation by filling spacers with arbitrary angles or adhesive curable resin. It is the joiner who made it.

Further, the multi-directional structural plate joining joiner of the present invention has a U-shaped cross section holding section for inserting and connecting the side portions of the structural boards to be joined adjacent to each other, and the back surfaces of the holding sections face each other. Then, a central space is formed by the back surface, and fixing means such as a spacer or an adhesive curable resin for filling the back space is provided, and the central space is filled and fixed with the spacer or an adhesive curable resin, and at least one The side face of the sandwiching part can be removed, and the side face of the sandwiching part can be changed so that the position of the side face of the sandwiching part can be changed. It has a sandwiching part that inserts and connects the sides of the sandwiching part, and the sandwiching part is connected with the back faces of the sandwiching part facing each other, and the insertion structure plate and the sandwiching space are filled and fixed with a spacer or adhesive curable resin. To form a multi-directional structural plate That is the summary.

[0007]

[Action]

 The U-shaped cross-section holding part that fits and joins the side parts of the structure plates to be joined adjacent to each other is inverted, and one corner of the back face of the holding part is joined while the other back face is open. With the fulcrum as a fulcrum, as shown in FIG. 3, by rotating both holding portions to the outside by a required angle, it is possible to form an arbitrary angle (0 to 180 degrees) between the back surfaces. Since the back space of an arbitrary angle groove surrounded by the back surface is filled and fixed with a spacer or an adhesive curable resin or the like to form a polygonal arbitrary body, the formed arbitrary angle can be surely fixed. In addition, since the adhesive curable resin or the like can be freely deformed, it is possible to easily fill the back space of the arbitrary groove. A through hole protrusion is provided in the joiner holding part for fixing the fitting structure plate body, and a dovetail groove and a through hole prepared in the groove back space are provided in the groove back space so that a space such as a spacer or an adhesive curable resin is It enables fixation and helps prevent disengagement. In addition, by providing the through hole, the structural plate body inserted in the sandwiching portion and the filled adhesive curable resin can be bonded to each other, so that the fixing becomes more reliable and the deformation can be prevented.

Further, by providing the groove back opening protrusion on the extension line of the open side surface, it is possible to more reliably fill the spacer and the adhesive curable resin, etc., and prevent the deformation. Further, since the side surface position of the holding portion can be changed, the thickness of the structural plate body used can be changed at any time.

【Example】

 Hereinafter, a few embodiments of the present invention will be described in detail with reference to FIGS. Embodiment 1 FIG. 1 shows a first embodiment of the present invention, and in the drawing, it is assumed that the structural plate bodies 10 are joined at right angles to each other. 1 is a polygonal structure plate joining joiner main body, 2 is a holding part, 3 is a joining part, 3a is a bending groove, 4 is a through hole provided in the groove back surface 5, 6 is a groove back opening protrusion, 7 is a hole, 8 Is a joint side surface, 9 is an open side surface, 10 is a structural plate body, and 11 is a groove back opening.

The polygonal structure plate joining joiner of the present invention is bent so that the joining side surfaces 8 are brought close to each other when forming an arbitrary angle, and therefore the material used must be a flexible material. , Resin, composite material, etc. are conceivable. In this embodiment, aluminum is used, and the U-shaped cross-section holding portion 2 is inverted back to back like 1 and the inner joint side surfaces 8 of the holding portion side surfaces 8 and 9 are joined at the joint portion 3 of FIG. The bending groove 3a is provided to facilitate bending. In addition, through holes 4 are formed in two rows on the back surface 5 of the groove. The open side surface 9 is provided with holes 7 such as nails and screws for fastening the inserted structural plate body. Further, a groove back opening protrusion 6 is provided on the groove back side extension of the open side surface 9.

An actual method of joining structural plate bodies using the polygonal structural plate joint joiner 1 having such a configuration is as follows. First, according to the angle of the joint corner to be formed, the sandwiching portion 2 of the polygonal structure plate joint joining joiner 1 is bent so that the joint portion 3 is located close to each other. Next, the structural plate body 10 is inserted into the holding portion 2 as far as it will go. At this time, since the retaining projection 12 is provided at the entrance of the holding portion 2, that is, the end portions of the side surfaces 8 and 9, the structural plate body once inserted does not easily come off. Finally, the groove back opening 11 formed by bending the holding portion 2 is filled with an adhesive curable epoxy resin caulk 15 or the like.

FIG. 2A shows a sectional view after the filling. As is clear from the figure, the adhesive curable resin 13 is firmly fixed and prevented from being deformed by the groove back opening projections 6, and the resin that has permeated through the through holes 4 provided on the groove back surface 5 is structural plate body. By adhering with, the structure plate can be fixed, and it is also useful for fixing the filler and preventing deformation.

Embodiment 2 In this embodiment, the filling material of the groove 11 is the spacer 14 shown in FIG. 2B, and the dovetail groove 15 is provided in the spacer. The state in which the spacer 14 is inserted is shown in FIG. Since the spacer 14 is firmly fitted to the groove back surface 5 by the dovetail groove 15, the groove back opening projection 6 ′ is formed shorter than that of the first embodiment. In addition, the groove back opening projection fitting portion is also provided with a triangular projection 14 'on the spacer side so that the spacer does not easily come off.

In the polygonal structure plate joining joiner having such a structure, after the structure plates are inserted and fixed in the same manner as in the first embodiment, the groove-back opening-shaped spacer 14 is slid to fit the shape of the dovetail groove 15. By inserting into the back opening, the shape of the groove back opening is firmly fixed, and it does not come out of the groove back opening. In this way, when the joining angle is fixed, for example, at a right angle, 45 degrees, 60 degrees, 30 degrees, etc., the shape of the groove back opening can be specified in advance, so a spacer suitable for that shape can be used. .

Embodiment 3 This embodiment is shown in FIGS. 3 and 4, and shows an example in which six plates are used to form a hexagonal column. A dovetail groove 15 is provided on the groove back surface 5. Further, in this embodiment, since the bending angle of the holding portion 2 is 60 degrees, the spacer 16 shown in FIG. 3 is inserted into the groove back opening. FIG. 4 shows the finished shape.

Embodiment 4 This embodiment is shown in FIG. 5 (a), and is an H-shaped multi-directional joining joiner used when assembling structural plates vertically and horizontally like a display shelf or a shoe box. is there. Although such an H-type joiner has been used in the past, the spacer 14 and the adhesive curable resin 13 were not used in the central portion 17. Also, there were no dovetail grooves, through holes, or slip-out preventing projections in the holding part. According to the present invention, since the central portion 17 is filled and fixed with the spacer 14 and the adhesive curable resin 13 after joining the structural plates, a shelf for joining the multi-directional structural plates that is even stronger is obtained. .

Embodiment 5 This embodiment is shown in FIG. 5 (b), and each holding portion is not formed in a U-shaped cross section, but the back surface is triangular pyramid-shaped, that is, each holding portion boundary surface 18 is cross-sectioned. In Example 4, it is formed in a cross shape, and the central space in Example 4 is eliminated. Also in this case, when a space is formed between the structural plate and the boundary surface 18 serving as the triangular back surface, it is preferable to fill the adhesive curable resin or the like.

Embodiment 6 This embodiment is shown in FIG. 6 and is a triangular joiner. The same thing as in Embodiment 4 applies to this embodiment. Further, also in the triangular joiner, the boundary surface may be formed in a cross shape as in the fifth embodiment.

Embodiment 7 This embodiment is shown in FIG. 7, which enables joining of structural plates from three directions. In this embodiment, one side of the sandwiching portion side surface 19 is replaced. The free grooves 19a19b are provided in the holding portion. With such a structure, when the plate thickness is thin as A, the sandwiching portion 2 suitable for the plate thickness A can be formed by inserting the sandwiching portion side surface 19 into the groove 19a and the plate thickness B as shown in FIG. If it is very thick, inserting the side surface 19 of the holding portion into the groove 19b makes it possible to form the holding portion 2 suitable for the plate thickness B. Moreover, since the dovetail groove and the through hole are provided in the central portion 17 and the spacers 13 and the adhesive curable resin 13 are filled and fixed, the structural plate body from three sides having different plate thicknesses which is more excellent in strength can be obtained. It enables joining.
