Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, since a new floor is provided with a predetermined space above the floor slab, a joist holding that can adjust the height of the joist as the base is held. Regarding metal fittings.

[Prior Art] FIGS. 3 and 4 show a conventional joist holding metal fitting.

In each drawing, 1 is a joist holding metal fitting for holding a joist 2 having a square cross-section as a base material for attaching the floor board, which is a board 3 grounded to the floor slab S and a bolt planted on the board 3. 4 and a lock nut 5 screwed to the bolt 4.
And the washer 5a, the leg 6 made of a cylinder body which is caulked and fixed to the center of the joist placing board 7 and has an internal thread formed in the hole, and the joist 2 placed on the joist placing board 7 from above. It is composed of a tightening band 8 formed in an inverted U shape from a thin sheet metal or the like so as to be covered, and a cushion material 7a is adhesively fixed to the joist placing board 7 and is interposed below the joist 2, and on the upper surface of the joist 2. Next to the tightening band 8, a cushion material 8a is provided for preventing a collision noise between the joist 2 and the floor material and for correcting the thickness of the tightening band 8. In addition, a slit 9 is formed in substantially the center of both sides of the joist mounting plate 7, and the tip 8t of the tightening band 8 is inserted into the slit 9 and bent to fasten the joist 2. Reference numeral 3a is a hole for increasing the adhesive force between the floor slab S and the substrate 3.

With the above configuration, when the joist 2 is arranged, the ground ink is put out on the floor slab S, the joist holding metal fittings 1 are arranged on both ends of the joist to be arranged based on this, and After fixing the substrate 3 to the floor slab S with an adhesive and adjusting the height by rotating the joist mounting plate 7, both ends of the joist 2 are mounted on the mounting plate 7 of the joist holding metal fitting 1. Then, fix with the tightening band 8. And the middle part of joist 2 is a joist 2 at a predetermined interval.
The joist holding metal fittings 1 are arranged underneath, and the joist holding metal fittings 1 are adjusted so that the cushion material 7a on the joist placing plate 7 contacts the lower surface of the joist 2.

[Problems to be Solved by the Invention] However, according to the conventional joist holding metal fitting described above, since the leg body 6 fixed by caulking is provided below the joist placement plate 7, as shown in FIG. Even if the leg 6 which is integrated with the joist mounting plate 7 is lowered to the bottom and the height of the joist 2 is set to the lowest, the joist 2 can only be set to a position higher than the height of the bolt 4. However, it was not suitable for setting joist 2 lower. That is, the height of the floor must be adjusted within the range of the height of the leg 6, and the height of the tip of the bolt 4 must be screwed into the leg 6. In order to lower the joists 2, the legs 6 must be shortened, and in that case, the adjustment amount becomes smaller and smaller. Next, in terms of workability, the bottom lock nut 5, which cannot be seen from above, must be tightened with a spanner or the like to fix the height after determining the height, which makes the groping work difficult and the upper leg 6 Since it was rotated with a spanner, it often turned up to the joist plate 7. In addition, since the legs 6 are supported by one bolt, they are weak against shaking during an earthquake or the like and are inferior in earthquake resistance and stability. Further, there is a drawback that the tightening band 8 is loosened and the joists 2 are lifted up due to aging, and the floor surface is out of alignment.

Therefore, according to the present invention, the position of the joist can be set to a lower position and the horizontal level of the joist can be set higher than the length (height) of the bolt to be used, and the height can be adjusted. It has enough margin and is excellent in workability, earthquake resistance,
The purpose is to obtain a joist holding metal fitting that is highly stable and can prevent joist rising.

[Means for Solving the Problems] The joist holding metal fitting of the present invention comprises a board to be grounded to a floor slab, bolts planted at both ends of the board, and a long member in a substantially inverted U-shaped cross section. There is a horizontal placing portion on which a joist is formed, which is formed so as to be continuous in the longitudinal direction and has horizontal pieces that are horizontally bent at both ends on the width side, and both sides of this horizontal placing portion are placed. Penetration holes for the bolts are formed at both ends extending more horizontally, and the bolts are attached to the bolts through the penetration holes, and a part of the ends is vertically arranged so as to be close to the tip end side of the horizontal piece. A joist mounting plate having a regulation piece formed by standing up, and screwed to the bolt so as to be positioned below both ends of the joist mounting plate,
A lower nut for holding the lower surfaces of both ends of the joist mounting board to adjust the height of the joist mounting board, and screwed to the bolt so as to be positioned above both ends of the joist mounting board. An upper nut for fixing the joist placing plate to the bolt by sandwiching both ends of the joist placing plate with the lower nut, and one side edge of one of the regulating pieces of the joist placing plate to the other. And a horizontal piece of the joist on the lower end while being bent in the direction of the joist through a line formed by extending a slit extending in the direction of the side edge of the slit and a line connecting the tip side of the slit and the upper end of the restricting piece. And a pressing piece that holds the upper surface of the horizontal piece of joist by this parallel portion.

[Operation] Since the horizontal placing portion and the both ends of the joist mounting plate are formed on the same plane, for example, when the upper and lower nuts are fixed at the upper end of the bolt, the upper surface of the joist is About the thickness of the joist is higher than the upper end of. That is, in the configuration of the present application, the upper surface of the joist, that is, the horizontal level of the joist can be set higher than the length (height) of the bolt to be used. Moreover, by bending the presser piece horizontally with pliers or the like toward the joist side, it becomes a parallel portion and the upper surface of the horizontal piece of the joist can be pressed, and lifting of the joist can be completely suppressed. In addition, since the uppermost nut that can be completely fixed after height adjustment can be quickly tightened with a box wrench or the like, workability is greatly improved. Also, since the mounting plate is supported by two bolts, it has excellent stability and earthquake resistance.
