(3) are formed and the joint ends of both panels (1) are abutted and the upper solid part (3) of the other panel (1) is placed on the lower solid part (2) of one panel (1). A so-called phase cut method was used in which they were piled up and fixed to the lower ground material (21) with nails (11A) or the like from above.

However, in such a phase inversion method, the nail head (11B) is exposed to the outside and the appearance is impaired, and the joint ends of both panels (1,1) are closely contacted. Therefore, if the panel (1, 1) expands or contracts due to changes in temperature, humidity, etc., the panels (1, 1) interfere with each other and rise or break, or the panel (1, 1) There is a problem that the gap at the joint end of the becomes large and the appearance is deteriorated.

A method using a metal fitting for connecting the panels to each other is also provided. In this method, for example, as shown in FIG. 8, a lower actual pressing section (14) and an upper actual receiving section (15) are provided at the upper edge of the driving section (13) having a sharpened section (12) at the lower end. Using the metal fitting (11), as shown in FIG. 9, the driving portion (13) of the metal fitting (11) is vertically driven into the base material (21), and the lower actual pressing portion (14) of the metal fitting (11) is ) And the base material (21), the lower real part (2) of one panel (1) is inserted, and the upper support part (15) of the metal fitting (11) and the base material (21) are A ridge (9) protruding from the inside of the upper solid part (3) of the other panel (1) is inserted between them, and the upper solid part (3) of the other panel (1) is inserted into one of them. Join a pair of panels (1,1) by stacking them on the lower real part (2) of the panel (1).

[0005]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-described conventional joining of panels using metal fittings, nails and the like are not driven into the panels to be fixed. However, since the driving part (13) of the metal fitting (11) is driven vertically into the base material (21), the notch (16) is formed on both edges of the driving part (13). However, the metal fittings (11) are easily separated from the base material (21), and the end face of the upper solid part (3) of the other panel (1) is below the one panel (1). Of the two steps (2A, 2B) formed on the upper surface of the real part (2), it is in close contact with the step part (2A) on the lower real part (2) root side, and the panel (1, 1) If they expand or contract, they may interfere with each other and rise up or be damaged, or the gap between the joint ends of the panel (1,1) may become large and the appearance may deteriorate. Further, since the panel (1,1) and the base material (21) are in close contact with each other, moisture cannot escape, and the panel absorbs moisture, so that the warpage is likely to occur.

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 to 6. (11A) is a metal fitting which is a horizontal base portion (12A) and is inclined from both ends of the horizontal base portion (12A) obliquely downward. Base (16A) consisting of a pair of inclined parts (13A, 14A) and a leg plate part (15A) extending substantially horizontally from one inclined part (13A), and the base (16A). ) Of the horizontal base part (12A) of the trunk plate part (17A) standing substantially vertically from the upper surface, and a pair of branch plate parts (18A, 18A, which branch diagonally upward at the tip of the trunk plate part (17A)). 19A), one inclined portion (13A) of the metal fitting (11A) is made thicker than the other portion, and a plurality of nail holes (20A) are provided, and the leg plate portion (15A) is further provided. Three vertical holes (21A) are provided, and the horizontal base (12A) of the base (16A) and the pair of branch plates (18A, 19A) are provided on both sides of the trunk plate (17A). A pair of panel fitting portions (22A, 23A) are formed between which a gap is widened next to the outside. Further, both edges (24A, 24A) of the metal fitting (11A) are bent.

A method of joining the panels (1A, 1A) using the metal fitting (11A) will be described below. First, the metal fitting (11A) is fixed to the base material, but when the base material is steel frame or wood, the metal fitting (11A) is passed through the vertical hole (21A) of the leg plate portion (15A) of the metal fitting (11A) ( 11A) is screwed, and when the base material is wood, the metal fitting (11A) is nailed through the nail hole (20A) of the inclined portion (13A). FIG. 3 shows a state in which the metal fitting (11A) is fastened to the base material (24) made of wood by screwing the screw (25) into the vertically long hole (21A) of the leg plate portion (15A). When fixing the metal fitting (11A) to the base material (24) with the screw (25), adjust the mutual position of the screw (25) and the vertical hole (21A) of the foot plate part (15A) of the metal fitting (11A). By doing so, the vertical mounting position of the metal fitting (11A) is adjusted.

At the joint end of the lower panel (1A) of the panels (1A, 1A) joined by such metal fittings (11A), the thickness gradually decreases toward the tip as shown in FIG. The lower solid part (2A) having the insertion part (2'A) is formed, and at the joining end of the upper panel (1A), the upper solid part (3A) and the upper solid part are formed as shown in FIG. An insertion part (3'A) that gradually decreases in thickness toward the tip is provided on the inside of (3A). The sealing material (26) is placed on the insertion part (2'A) of the lower real part (2A) of the lower panel (1A), and the insertion part (2'A) is shown in FIG. Insert the fitting (3'A) inside the upper real part (3A) of the upper panel (1A) into the bracket (23A) on the lower side of the fitting (11A). Insert it in the panel fitting part (22A) on the upper side of 11A). At this time, the panel fitting parts (22A, 23A) of the metal fittings (11A) have wider gaps toward the outside, and the insertion parts (2'A, 3'A) of the panels (1A, 1A) have tips. Since the thickness is reduced toward, the insertion part (2'A, 3'A) of the panel (1A, 1A) can be easily inserted into the panel fitting part (22A, 23A) of the metal fitting (11A). . Then, the upper panel (1A) moves slightly downward by its own weight, and the insertion part (3'A) inside the upper solid part (3A) comes into close contact with the upper panel fitting part (22A) of the metal fitting (11A). Also, the metal fitting (11A) is pushed by the upper panel (1A) so that the lower real part (2A) of the lower panel (1A) is inserted into the insertion portion (2'A) of the metal fitting (11A). The panel fitting part (23A) on the side is in close contact, there is no rattling, and good sealing performance is obtained.

In such a joined state, the upper solid portion (3A) of the upper panel (1A) overlaps the lower solid portion (2A) of the lower panel (1A), and the upper solid portion (3A) ) Is not in contact with the root end step portion (4A) of the lower solid portion (2A), so when both of the panels (1A, 1A) expand and contract, the upper solid portion (3A) is replaced by the lower solid portion (2A). ) There is no possibility that the upper solid portion (3A) abuts against the stepped portion (4A) of the lower solid portion (2A) and presses it by sliding on the upper side. Further, the screw (25) can be driven obliquely into the vertically long hole (21A) of the leg plate portion (15A), so that the metal fitting (11A) has a great pulling strength.

Further, the head of the screw (25) does not interfere with the panel (1A, 1A) and does not go out to the surface of the panel (1A, 1A). Even if the base material (24) is uneven, the slanted parts (13A, 14A) of the metal fitting (11A) can be elastically deformed, which, in combination with the rigidity of the panel (1A, 1A), The surface of the panel (1A, 1A) can be finished so as to be substantially on the same plane so that there is no unevenness, and the appearance can be made extremely good. Further, as described above, since the inclined portions (13A, 14A) of the metal fitting (11A) can be elastically deformed, the external force exerted on the panel (1A, 1A) can be absorbed. Since the panel (1A, 1A) has a gap between the base material (24) and the thickness (height) of the base (16A) of the metal fitting (11A), it is easy for moisture to escape, so that the panel (1A, 1A) ) Has no warpage due to moisture absorption.

Other than the present embodiment, the number of the vertical holes (21A) of the leg plate portion (15A) of the metal fitting (11A) may be one or two, and when the base material is wood, the inclination of the metal fitting (11A) The nail may be driven in and fixed through the nail hole (20A) of the portion (13A). Furthermore, both end edges (24A, 24A) of the metal fitting (11A) do not necessarily have to be cylindrical.

[0014]

[Effect of device]

 Therefore, in the present invention, since the metal fitting is fixed to the base material by screwing the screw or the like obliquely into the vertically elongated hole of the leg plate portion of the horizontal base, the pull-out resistance is large and the metal fitting is firmly fixed to the base material, and The vertical position of the metal fitting can be adjusted by adjusting the relative position between the vertically elongated hole and the screw, and the panel fitting part of the metal fitting gradually widens outward, so that Fitting of the insertion part of the panel becomes easy, and the adhesion is extremely good, and there is no rattling, and excellent sealing properties are obtained. In addition, since the heads of the screws that fix the metal fittings in the panel joint state are covered from the outside without interfering with the panel, the appearance is extremely good, and a gap is formed between the panel and the base material. Therefore, the panel does not absorb moisture and thus does not warp, and since the upper part of the upper panel is superposed on the lower part of the lower panel, the temperature and humidity When the panel is stretched due to a factor, the upper solid part of the upper panel and the lower solid part of the lower panel are relatively slid to absorb such expansion, and the panel is raised or damaged. Is certainly prevented.
