[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening member for a building plate which can easily fix a rectangular plate forming an outer wall of a building to a base material.

[0002]

2. Description of the Related Art Conventionally, a rectangular building plate (hereinafter referred to as a plate) is fixed to a base material to form an outer wall, as shown in FIG. A plate material 1 in which a nut 2 is embedded is used.

[0003] As a base material, an angle material 4 is used, in which one surface 4a is projected from the steel beam 3 and the other surface 4b is welded to the steel beam 3 so as to be vertical.

In order to fix the plate material to the angle member 4, a bolt 6 inserted through a bolt hole of a piece-shaped Z clip 5 is screwed into the long nut 2, and the angle between the Z clip 5 and the plate material 1 is adjusted. One side 4a of the material is clamped and fastened with bolts 6.

[0005] However, the above-mentioned conventional method has a drawback that not only is it troublesome to manufacture a plate material to which the long nut 2 is attached, but also a skilled person is required in on-site construction for attaching the long nut 2 with bolts.

[0006]

The problem to be solved is that the use of a plate material that requires a lot of manufacturing time and the need for skilled personnel for on-site construction.

[0007]

According to the present invention, a vertical groove is formed, and opposing long holes are formed on both side surfaces of the groove, and the opposing long holes are formed at a joint portion of a building plate to be fastened. A plurality of sets of base materials are provided at intervals in the vertical direction in accordance with the position, and an L-shaped cross section in which the tips are respectively inserted into the opposed long holes on both sides along the groove bottom surface of the base material. When the support plate portions are integrally connected and the tips of the support plate portions on both sides are inserted into the opposed slots, the flat plate portion located outside the groove of the base material and the lower end of the flat plate portion are integrated. And a fastener that includes a locking plate portion that is connected to the support plate portion and protrudes to a side opposite to the support plate portion, and a leading end portion is a locking portion that locks a joint portion of the plate material. The use of a fastening member is a means for solving the problem.

[0008]

Since the fastening member of the present invention has the above-described structure, the fastener is attached to the base material by fitting the support plate portion of the fastener into the long hole of the base material. The plate material is locked by the locking plate portion of the fitting.

[0009]

1 and 2 show an embodiment of a fastening member for a building plate according to the present invention. The following description will be made with reference to a case where a connecting portion of a plate is real.

In the figure, reference numeral 11 denotes a base material, in which a vertical groove 12 is provided. On both sides 14, 14 of the bottom surface 13 of the groove 12, opposing vertical holes 1
5 are drilled. A plurality of pairs of the opposed slots 15 are provided at intervals in the vertical direction in accordance with the position of the joint of the plate material to be attached.

Reference numeral 16 denotes a fastener. The fastener 16 includes a flat plate 17 along the groove bottom surface 13 of the base material, a support plate 18 having an L-shaped cross section integrally connected to both sides of the flat plate 17, and a lower end of the flat plate 17. The locking plate 19 is integrally formed, protrudes to the opposite side of the support plate 18, and has a locking portion 19 a whose distal end locks a joining portion of the plate material. The fastener is a flat plate portion 17.
When the front end of the support plate portion 18 is inserted into the long hole 15, the dimension is determined so as to be located outside the groove.

In order to fasten a plate material using a fastening member consisting of the base material 11 and a fastener (hereinafter referred to as a "fitting") 16, as shown in FIGS.
The tips of the support plates 18 of the metal fitting 16 are inserted into the fittings 5 and 15. Insertion is facilitated by placing the bracket 16 sideways into the groove 12 and rotating it by 90 °. The locking plate 1 of the metal fitting 16 thus attached to the base material 11
9 presses the male member 20a of the plate member 20. Next, the female member 20b of the upper plate member is fitted to the male member 20a, and the male member of the upper plate member is pressed by the locking plate of the metal fitting attached to the upper portion. By performing this operation from the bottom to the top, the plate can be easily fastened.

As shown in FIG. 5, the metal fitting 11 is formed by bending the supporting plate 18 to form a supporting plate 18 having a vertically projecting ridge 21 abutting on the groove bottom 13.
When the tip of 8 is inserted into the long hole 15, if the ridge 21 is pressed against the bottom surface 13 by the spring effect, the engagement between the base material 11 and the metal fitting 16 becomes strong.

As shown in FIG. 6, hooking claws 22 are provided at the lower ends on both sides of the locking plate 18, and when they are hooked on the lower end of the long hole 15 of the base material, the movement in the left-right direction is prevented.

Further, as shown in FIG. 6, a rib 23 having a protruding surface may be provided at the base of the flat plate portion 17 and the locking plate portion 19 to increase the bending strength. The rib 23 may have a concave shape.

Further, in the above description, the locking plate portion 19 is provided at the lower end of the flat plate portion 17, but may be provided at the upper end as shown in FIG.

Further, in the above description, the joining portion of the plate material is made into a real, and the locking plate portion 19 is made to have a shape along the real. However, the present invention is not limited to this. A locking plate having a conventionally known shape is used according to the shape of each joint. For example, in the case of a decision, the result is as shown in FIG.

[0018]

[Effect of the Invention] As described above, the fastening member of the building plate material according to the present invention is obtained by attaching the support plate portion of the metal fittings manufactured at the factory to the base material having grooves and slots at the factory. Therefore, the work at the site can be greatly reduced, the plate can be efficiently fastened without any need for manual operation, and the construction cost is advantageously reduced.
