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. 6 and 7 show a conventional joist holding metal fitting.

In each drawing, 1 is a joist holding metal fitting for holding joists 2 as a base material for attaching the floor board, which is a board 3 grounded to the floor slab S, and bolts 4 planted on the board 3.
A lock nut 5 and a washer screwed to the bolt 4.
5a, a leg 6 made of a cylindrical body in which a female screw is formed in a hole that is caulked and fixed to the center of the joist placing board 7, and a joist placing board 7
It consists of a tightening band 8 formed in an inverted U shape so as to cover the joist 2 placed on the bottom of the joist 2, and the cushion material 7a is adhered and fixed to the joist placing plate 7 below the joist 2. A cushion member 8a is provided beside the tightening band 8 on the upper surface of the joist 2 to prevent the collision noise between the joist 2 and the floor material and to correct the thickness of the tightening band 8. Also,
Slits 9 are formed substantially at 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 mounting plate 7 abuts the lower surface of the joist 2.

[Problems to be Solved by the Invention] However, according to the conventional joist holding metal fitting, since the leg body 6 fixed by caulking is provided under 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. Moreover, since the legs 6 are supported by one bolt, there are drawbacks such as weakness in shaking during earthquakes and the like, and poor seismic resistance and stability.

Therefore, according to the present invention, the height of the joists can be set to a lower position, and further, the height adjustment is sufficient, and the workability is excellent.
The purpose is to obtain a joist holding metal fitting that is also highly earthquake resistant and stable.

[Means for Solving the Problems] A joist holding metal fitting of the present invention includes a board to be grounded on a floor slab, and a joist placing board on which the joists are placed and which has a substantially rectangular shape having a width slightly wider than the joists. An adjusting portion composed of bolts and nuts planted from the base plate in order to vertically adjust two corners of the joist placing plate, which are located on a diagonal line, and both side portions of the joist placing plate. And a tightening band which is formed in an inverted U shape so as to cover the joist from above and has a tip inserted into the slit and bent.

[Operation] Since two corners located on the diagonal line of the joist mounting plate are held by the adjusting part, and the joists are placed on the joist mounting plate between the bolts of this adjusting part, the height of the bolts The joist mounting plate can be lowered to a low position, and a height adjustment margin corresponding to the height of the joist can be provided. 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.

[Embodiment of the Invention] Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

In each drawing, reference numeral 11 denotes a joist holding metal fitting of the present invention, which is a board 12 which is grounded to the floor slab S and a joist 2 on which the joist 2 is placed and which has a slightly wider width than the joist 2. Placement plate 13, two corner portions 14 and 14 located on the diagonal of the joist placement plate 13, and these corner portions 14 and 14
Are the bolts 15 planted in the substrate 12 and the bolts 15
