Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a floor support device used to support the floor of a building.

(Prior Art) Conventionally, various configurations have been considered as support devices for supporting the floor of a building. There are also types in which bundled pillars are installed on the foundation, and overlays and joists are spread over the bundled pillars via buffer members.

However, in conventional floor support devices,
There was still room for improvement, as the structure was required to be simple, easy to construct, and mass-producible.

(Purpose of the invention) This invention was made in view of the above-mentioned conventional demands, and provides a floor support device for buildings that has a simple structure, is easy to construct, and is also suitable for mass production. It is intended to.

(Structure of the invention) The floor support device for a building according to this invention includes a receiving plate provided at the lower end of an adjustment bolt on an elastic member disposed on a foundation, and a plate-formed bolt support fitting that is penetrated by the adjustment bolt. penetrating the receiving plate with a bent downward fitting piece provided on the receiving plate and fitting the elastic member;
A plywood is placed on the upper surface of the flat floor support fitting screwed onto the adjustment bolt, and the flat floor support fitting is connected to a presser plate fitted into a horizontal groove provided in the middle part of the side end surface of the plywood. The invention is characterized in that a portion of the plywood below the horizontal groove is clamped and fixed by tightening bolts between the plywood and the horizontal groove.

(Example) FIGS. 1 and 2 are a front view and an exploded slope view, respectively, of a floor support device according to an example of this invention.

In the figure, 1 is a foundation, 2 is an elastic member made of molded rubber, 3 is a receiving plate, 4 is a nut, 5 is an adjustment bolt, 6 is a plate molded bolt support metal fitting, 7 is a flat plate floor support metal fitting, and 8 is a presser plate. , 9 is a fixing bolt, 10 is plywood, and 11 is a finished flooring material.

Among these, the elastic member 2 is manufactured using a rubber mold, and in this embodiment has a cylindrical shape and has two parallel fitting holes 21 and 22. It is.

Further, the receiving plate 3 has approximately the same diameter as the elastic member 2, and in this case also has through holes 31, 32 at the same positions as the fitting holes 21, 22 formed in the elastic member 2. At the same time, a nut 4 is welded and fixed approximately at the center.

Further, the adjustment bolt 5 is fixed to the upper surface of the receiving plate 3, and has a groove 51 formed at its upper end, and is fixed to the receiving plate 3 by screwing the lower end into the nut 4. It has been done.

Furthermore, the plate-molded bolt support fitting 6 has a burring-molded through hole 61 formed in its center portion through which the adjustment bolt 5 can be inserted, and downward flanges 6 formed by bending at both ends.
2,63 is provided, and this downward flange 6
2 and 63 each have a downward fitting piece 6 in the extension direction.
4,65 are formed. The bent downward fitting pieces 64 and 65 are connected to the through holes 31 and 32 formed in the receiving plate 3 and the fitting holes 2 formed in the elastic member 2.
1 and 22, respectively.
A retaining claw portion 66, 67 is formed on each of them.

Furthermore, a female threaded hole 71 into which the adjustment bolt 5 can be screwed is formed at approximately the center of the flat floor support metal fitting 7 by burring molding and tapping processing, and this female threaded hole 7
Female threaded holes 72, 73 for screwing in the fixing bolts 9, 9 are formed on both sides of 1, and downward flanges 74, 75 are formed on both ends.

Further, a through hole 81 into which the adjustment bolt 5 can be fitted is formed in the holding plate 8 at a substantially central portion thereof, and the stop bolts 9 are fitted into both sides of the through hole 81. A through hole 82 that can be inserted,
83 is formed.

Furthermore, a horizontal groove 1 is provided in the middle portion of the side end surface of the plywood 10, into which the presser plate 8 is inserted.
01 is provided.

Next, when supporting the floor using each component with such a configuration, first, the elastic member 2 is attached to the base 1.
After placing the nut 4 in the specified position,
The receiving plate 3 which has been fixed by welding and fixed by screwing the adjusting bolt 5 is placed on the elastic member 2, and then the downward fitting pieces 64, 65 of the bolt support fitting 6 are attached to the receiving plate 3.
The adjustment bolt 5 and the elastic member 2 are fixed by fitting into the through holes 31, 32 provided in the elastic member 2 and the fitting holes 21, 22 provided in the elastic member 2. Furthermore, as mentioned above,
Of course, it is also possible to fix the elastic member 2 and the adjustment bolt 5 using the bolt support fitting 6 and arrange it at a predetermined position on the foundation 1.

Next, the height of the floor support fitting 7 from the foundation 1 is adjusted by screwing the adjusting bolt 5 into the female threaded hole 71 of the floor support fitting 7 and rotating the floor support fitting 7 appropriately.

Next, after placing the end of the plywood 10 on the floor support fitting 7, the presser plate 8 is inserted into the horizontal groove 101 provided in the middle part of the side end surface of the plywood 10, and the through hole formed in the presser plate 8 is inserted. Insert the fixing bolts 9, 9 through 82, 83 and screw them into the female screw holes 72, 73 of the floor support fitting 7. By screwing in the fixing bolts 9, 9, the portion of the plywood 10 below the horizontal groove 101 is sandwiched between the presser plate 8 and the floor support fitting 7, so that the plywood 10 is It is fixed on the floor support fitting 7. Thereafter, a buried timber 12 is placed between the plywood boards 10, 10, and a finished flooring material 11 is applied to complete the construction.

Therefore, the floor of the building can be constructed well, and at the same time, vibrations generated on the floor surface can be sufficiently absorbed by the elastic member 2.

(Effects of the invention) As explained above, according to the floor support device according to this invention, the elastic member disposed on the foundation
A receiving plate provided at the lower end of the adjustment bolt is installed, and a bent downward fitting piece provided on a plate-formed bolt support fitting passed through the adjusting bolt is passed through the receiving plate and fitted to the elastic member. , a plywood is placed on the upper surface of the flat floor support fitting screwed onto the adjustment bolt, and a presser plate is fitted into a horizontal groove provided in the middle part of the side end surface of the plywood, and the flat floor support fitting is Since the structure is such that the part of the plywood below the horizontal groove is clamped and fixed by tightening bolts between The component parts of the floor support device can be manufactured easily because they can be easily formed by, for example, the adjustment bolt. Since the elastic member is fitted through the plate, the elastic member, receiving plate, and adjustment bolt can be accurately positioned relative to each other, and positional deviation in the rotational direction between the elastic member and the receiving plate can be prevented. Furthermore, since the plywood is placed on the top surface of the flat plate-shaped floor support bracket, it is less likely to receive local pressure. By inserting a presser plate into the horizontal groove and tightening bolts between the presser plate and the flat floor support fitting, the portion of the plywood below the horizontal groove is clamped and fixed. Therefore, it is possible to leave the upper surface of the plywood in a flat state, and by configuring the floor support device in this way, it is possible to better absorb vibrations, noise, etc. generated on the floor surface. The practical value of being able to do this is that it brings about very good effects.
