Abstract

(57) [Summary] [Purpose] The present invention provides a building hardware which is used for building a house and which can be easily worked when fixing wood to wood with hexagon bolts and nuts. According to the construction hardware of the present invention, in a construction hardware fixed with a hexagonal bolt and a hexagonal nut, two spherical or inclined convex portions are formed with point centers of bolt holes into which hexagonal bolts are inserted. It is characterized by the following. Further, the minimum distance between the protrusions is larger than 19 mm and smaller than 20 mm.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a building hardware used for building a house, and prevents a hexagon bolt and a hexagon nut from rotating together when the building hardware is fixed using a hexagon bolt and a hexagon nut.

[0002]

[Prior art]

 In the case of conventional hardware that is fixed with hexagon bolts and hexagon nuts, only bolt holes were formed in the flat metal.

[0003]

[Problems to be solved by the invention]

 The architectural hardware of just drilled bolt holes in the planar hardware, tightening the other by suppressing a wrench or the like either to prevent co-rotation of hex bolts and hex nuts using another spanner There is a problem that it is necessary to fix the device by hand, two tools are required, and it is necessary to use both hands when tightening, which makes the operation difficult.

[0004]

[Means for Solving the Problems]

 The architectural hardware of the present invention has two spherical or sloped projections (point-symmetric with respect to the center of the bolt hole (1) into which the hexagon bolt is inserted) in the architectural hardware fixed by the hexagon bolt and the hexagon nut. 2) is formed. Also, in a building hardware fixed with a hexagon bolt and a hexagon nut, two spherical or inclined convex portions (2) are formed with the center of the bolt hole (1) for inserting the hexagon bolt being point-symmetrical, The minimum distance between the bulges of the convex portions is larger than 19 mm and smaller than 20 mm.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a washer, and FIG. 2 is a side view when bolts are tightened. The washer (5) is one of the construction hardware (1), and is widely used as a washer for fixing wood (9) with a hexagon bolt (6) and a hexagon nut (8). In the figure, a bolt hole (2) is formed in the center of the washer (5), and two spherical or inclined convex portions (3) are formed with the center of the bolt hole (2) being point-symmetrical. . Further, the minimum interval (4) between the two convex portions (3) is formed to be larger than 19 mm and smaller than 20 mm. Since the building hardware (1) of the present invention is configured as described above, when this is used, the hexagonal head (7) of the hexagonal bolt (6) passed through the bolt hole (2) becomes two convex portions (3). When the hexagonal nut (7) on the opposite side enters between the and the convex part (3) and the opposite hexagonal nut (7) is tightened, the hexagonal head (7) of the hexagonal bolt (6) hits the convex part (3) and does not rotate. By tightening only the nut (7), the wood (9) can be fixed without the hex bolt (6) rotating together. The washer (5) on the hex nut (8) can rotate freely by turning the two protrusions (3) toward the wood (9), and the two bosses on the washer (5) can be rotated. Since the part (3) cuts into the wood (9), the effect of the fastening is increased.

As for the size of the hexagonal portion (7) of the head of the hexagonal bolt (6) used for construction, one having a short length of 19 mm or 21 mm is widely used. The distance between the protrusions (3) is larger than 19 mm and smaller than 20 mm, and the protrusions (3) are formed into a spherical shape or a slope so that the 19 mm bolts are fixed to the washer, and the 21 mm bolts are fixed to the protrusions. It is fixed so as to ride on (3), and can accommodate both 19 mm and 21 mm hexagon bolts (6).

【Example】

 3 is a front view of the blade bolt, FIG. 4 is a side view of the blade bolt, and FIG. 5 is an explanatory view of using the blade bolt. In the figure, two bolt holes (2) are formed in the fixing portion (11) of the blade bolt (10), and three convex portions (3) are formed symmetrically about the center of the bolt hole (2). ing. By using such a blade bolt (10), when fixing the wood (9) to the wood (9), the size of the hexagonal part (7) of the head can be reduced to two types of hex bolts (6) of 19 mm and 21 mm. It is possible to use one of the two bolt holes (2), and it is possible to use one of the two bolt holes (2) with or without the counterbore (12) on the wood (9) to be fixed with the hexagon nut (8). The work proceeds with the use of.

[0008]

[Effect of the invention]

 By using the building hardware of the present invention, it is possible to prevent the hex bolt and hex nut from rotating together when fixing the wood with the hex bolt and hex nut. is there. Also, if the present invention is applied to a washer, the convex portion of the washer bites into the wood by directing the convex portion to the wood side, so that the effect of fastening and fixing is increased.
