[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a level adjustment pedestal capable of level adjustment for attaching a floor base material at a certain height from the foundation surface of a building.
[0002]
[Prior art]
Conventionally, as shown in FIG. 5, this type of level adjusting pedestal has conventionally been provided with a base member such as a slate plate or a particle board in which a nut member 23 having a metal adjusting nut 22 secured to the center of one surface of a metal pedestal plate 21 is used. 24, and an adjustment bolt 25 whose one end is in contact with the foundation surface G is screwed to the adjustment nut 22. By rotating this adjustment bolt 25, the floor under the floor from the foundation surface G is fixed. The height of the ground material 24 was adjusted.
[0003]
A circumferential groove 27 is provided in the top portion 26 of the adjustment bolt 25 so that the adjustment bolt 25 can rotate from the surface side of the floor base material 24, and the top portion 26 of the adjustment bolt 25 is previously provided in the floor base material 24. An attachment hole 28 through which the screwdriver can be seen is provided, and a minus driver fitted into the groove 27 of the adjustment bolt 25 can be inserted from the attachment hole 28.
[0004]
However, in the level adjusting pedestal 20 using the metal nut member 23, the nut member 23 must be fixed to the back surface side of the floor base material 24 with the wood screw or the tapping screw 11 from the back surface side in advance. The field work was troublesome.
[0005]
Further, recently, as shown in FIG. 6, a nut member integrally molded with a synthetic resin has been used because of demands for cost reduction and weight reduction.
[0006]
In the level adjustment pedestal 30 employing the synthetic resin nut member 33, it is considered that the nut member 33 is attached to the floor base material 24 from the surface side of the floor base material 24. 31 is not provided with a screw hole.
[0007]
[Problems to be solved by the invention]
Therefore, in order to attach the nut member 33 made of synthetic resin to the floor base material 24, as shown in FIG. 7, first, the gap 34 provided at the joint between the floor base materials 24, 24 or the floor base material 24 in advance. Attaching the nut member 33 to the back surface side of the floor base material 24 with the aim of the adjustment mounting hole 28 of the adjustment bolt 26 opened in the section, and temporarily fixing it with an adhesive or a small screw, then protruding from the nut member 33 The floor base material 24 is laid on the foundation surface G with the adjusted bolt 25 facing downward, and then the wood screw or the tapping screw 11 is screwed in and fixed to the base plate 31 from the surface side of the floor base material 24. .
[0008]
Therefore, as shown in FIG. 8, when the wood screw or tapping screw 11 is screwed into both the floor base material 24 and the base plate 31, the wood screw or tapping screw is interposed between the floor base material 24 and the base plate 31. Thus, the shavings 15 of the floor base material 24 scraped by 11 and the shavings 16 of the base plate 31 protrude. Therefore, not only the energy required for screwing the wood screw or the tapping screw 11 is increased, but the floor base material 24 and the base plate 31 cannot be in close contact with each other, so that the living in the building after the floor material is laid on the floor base material 24. Since then, the flooring could be obscured.
[0009]
The present invention was conceived to solve the problems of the conventional level adjustment pedestal as described above. The floor base material and the level adjustment base can be easily fixed, and the floor base material can be laid. It is an object of the present invention to provide a level adjusting pedestal for a floor base material that is easy and does not cause the floor material to stagnate after the floor material is laid on the floor base material.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0015]
FIG. 1 is a perspective view of a level adjustment base according to an embodiment of the present invention. FIG. 2 is a longitudinal sectional view of a state in which the floor base material is attached to the level adjusting pedestal according to the embodiment of the present invention. FIG. 3 is a plan view of the level adjustment base according to the embodiment of the present invention. FIG. 4 is a perspective view showing a state in which a floor base material is laid on the level adjustment base according to Embodiment 1 of the present invention.
[0016]
Embodiment 1 of the present invention shown in FIG. 1 has a rubber foot 1 as a non-slip that contacts the foundation surface G of the building at the lower end, and an adjustment bolt 2 extending upward from the rubber foot 1; And a nut member 4 provided with an adjustment nut 3 screwed into the adjustment bolt 2. The rubber foot 1 and the adjustment bolt 2 may be fixed integrally. However, the rubber foot 1 and the adjustment bolt 2 may be separate members so that the adjustment bolt 2 can rotate with respect to the rubber foot 1. desirable. Thereby, only the adjustment bolt 2 can be rotated without causing relative movement between the rubber foot 1 and the foundation surface G, and smooth level adjustment can be realized.
[0017]
The adjustment bolt 2 is preferably made of metal from the viewpoint of dimensions and strength, and the nut member 4 is preferably made of synthetic resin from the viewpoint of modeling.
[0018]
The adjustment nut 3 is provided at the center of the nut member 4, and a cylindrical rib 6 provided with a through-hole 5 having an axis substantially the same as the axis of the adjustment nut 3 is provided above the adjustment nut 3. Have. The cross-sectional shape of the through hole 5 is formed larger than the outer diameter of the adjustment bolt 3 and does not hinder the movement of the adjustment bolt 3. The front end portion of the cylindrical rib 6 has a shape and size that can be fitted into the mounting hole 8 opened in the floor base material 7. It has the contact surface 9 which contacts.
[0019]
Around the adjustment nut 3 of the nut member 4, there is a plate-like screw fixing portion 10 spreading in the horizontal direction. The screw fixing portion 10 is preferably a solid body having a thickness capable of being firmly fixed when a wood screw or a tapping screw 11 that does not require a pilot hole is screwed.
[0020]
Further, the screw fixing portion 10 is provided with a thin plate-like rib 12 directed upward, and a tip surface thereof constitutes a contact surface 9 that contacts the back surface of the floor base material 7. Thereby, the rib 12 serves as a spacer that separates the floor base material 7 and the screw fixing portion 10 to a predetermined size, and a gap 13 is formed between the back surface of the floor base material 7 and the screw fixing portion 10. Become.
[0021]
The thickness, number, and interval of the ribs 12 are determined in consideration of the size of the screw fixing portion 10 and the strength required for the nut member 4, and the arrangement thereof is as shown in FIGS. 1 to 3. There is no concern. That is, it is only necessary to ensure a sufficient contact surface 9 for keeping the floor base material 7 horizontal, and the rib 12 does not necessarily have to be provided around the outer periphery of the nut member 4. When the rib 12 is made into a thin plate shape as in the illustrated embodiment, even if the wood screw or tapping screw 11 is screwed into a position where it interferes with the rib 12, the rib 12 prevents the wood screw or tapping screw 11 from being screwed in. Therefore, there is an advantage that the operation can proceed without worrying about the screwing position of the wood screw or the tapping screw 11 with respect to the nut member 4.
[0022]
Next, a method for using the level adjustment base according to Embodiment 1 of the present invention will be described.
[0023]
First, the tip end portion of the cylindrical rib 6 of the nut member 4 is inserted into the mounting hole 8 opened in the floor base material 7 from the back side of the floor base material 7. At this time, if an adhesive is applied in advance to the contact surface 9 of the cylindrical rib 6 and / or the contact surface 9 of the rib 12, temporary fixing can be performed simply by placing the nut member 4 on the back side of the floor base material 7. Convenient because it can. Of course, you may temporarily fix with the wood screw or the tapping screw 11 without using an adhesive.
[0024]
On the other hand, on the foundation surface G, a level adjustment pedestal 14 is placed in advance according to the joint position of the floor base material 7, and the level adjustment pedestal 14 temporarily fixed to the mounting hole 8 on the upper surface of the nut member 4 is mounted. The floor base material 7 is laid down so that both end portions of the floor base material 7 are placed. When the laying operation is completed, the wood screws or tapping screws 11 are screwed in from the surface side of the floor base material 7 with the nut members 4 of all the level adjustment bases 14 being aimed. Then, the tip of the wood screw or the tapping screw 11 passes through the floor base material 7 and is screwed into the solid part of the screw fixing portion 10 of the nut member 4, so that the floor base material 7 and the level adjustment base 14 are firmly fixed. Is done.
[0025]
At this time, as shown in FIG. 2, the shavings 15 of the floor base material 7 scraped by the wood screw or the tapping screw 11 falls into the gap 13 between the contact surface 9 and the screw fixing portion 10, and the nut member 4 The shavings 16 of the screw fixing part 10 rises and enters the gap 13. Therefore, since the shavings 15 and 16 generated by screwing the wood screw or the tapping screw 11 do not enter the floor base material 24 and the contact surface 9 of the nut member, the floor material is laid on the floor base material 24. The flooring does not rub.
[0026]
Of course, the level adjustment base according to the present invention is not limited to the illustrated one, and various modifications can be made within the range of the purpose.
[0027]
For example, the contact surface 9 provided on the outer periphery of the intermediate portion in the longitudinal direction of the cylindrical rib 6 may be omitted if the contact surface 9 sufficient to keep the floor base material 7 horizontal can be secured by the ribs 12 alone. Moreover, it is not necessary that the tip surfaces of all the ribs 12 constitute the contact surface 9, and some of the ribs 12, 12, 12,... Are within a range in which the floor base material 7 can be kept horizontal. The tip surface may be formed lower than other tip surfaces. In this case, the rib 12 having a low tip surface can serve as a reinforcing member for the nut member 4 although it does not serve as the contact surface 9.
[0028]
In the illustrated embodiment, the adjustment nut 3 is provided at the lower end portion of the nut member 4. However, the adjustment nut 3 is not limited to this and may be disposed upward (on the cylindrical rib 6 side).
[0029]
Further, in the illustrated embodiment, the cylindrical rib 6 and the thin plate-like rib 12 are proposed as members constituting the contact surface 9, but the contact surface 9 separates the back surface of the floor base material 4 from the screw fixing portion 10. For example, a solid columnar body may protrude from the screw fixing portion 10 and the tip surface of the columnar body may be used as the contact surface 9.
[0030]
Moreover, as above-mentioned, although it is good to use a synthetic resin material for the nut member 4 at the point of the modeling property, it is not necessarily restricted to this. For example, you may use what is called artificial wood which mix | blended wood powder with thermoplastic resins, such as a polypropylene or polyethylene. Specifically, injection molding is possible as long as wood powder 51% (volume ratio) is blended with 49% polypropylene or polyethylene, and the formability is also good. And since the disposal as wood is recognized by mixing 51% of wood flour, it can be incinerated when it can no longer be used due to damage, etc., and it can be reused as a new injection molding material. It is also preferable for environmental protection.
[0031]
【The invention's effect】
As explained above, according to this invention of Claim 1, the level which has the adjustment bolt which adjusts the height from the foundation surface of a building, and the nut member which provided the adjustment nut screwed together to this adjustment bolt is provided. The adjustment base, and the nut member has a contact surface that contacts the back surface of the floor base material and a plate-like screw fixing portion that spreads horizontally to attach a wood screw or a tapping screw for fixing the floor base material. However, between the contact surface and the screw fixing part, the floor base material and the shavings of the screw fixing part generated by screwing a wood screw or a tapping screw from the surface side of the floor base material toward the screw fixing part may enter. because it gap is provided, since swarf caused by screwing the wood screw to tapping screws does not enter between the contact surface of the back surface and the nut member of the underfloor member, the floor above the underfloor member There is no such thing as flooring squeaky after a bed of.
[0032]
According to the second aspect of the present invention, since the contact surface is the tip end surface of the rib that is a part of the nut member, it is sufficient when the nut member is an integrally molded product made of a synthetic resin material. Since it is possible to remove the flesh and the resistance to prevent screwing is small even if the wood screw or tapping screw interferes with the rib, the work can proceed without worrying about the screwing position of the wood screw or tapping screw. In addition to the effect of item 1, it is possible to provide a level adjustment base that is lightweight, inexpensive, and has good workability.
[0033]
According to the third aspect of the present invention, the nut member is provided with a cylindrical rib having substantially the same axis as the axis of the adjustment nut and through which the adjustment bolt can pass, and the outer shape of the cylindrical rib. Since the shape can be fitted into the mounting hole opened in the floor base material, in addition to the effect of claim 1 or 2, positioning when temporarily fixing the level adjustment pedestal to the floor base material is easy. It becomes.
[0034]
According to the invention described in claim 4, since the contact surface is provided on the outer periphery of the cylindrical rib, it is not necessary to provide a rib constituting the contact surface near the adjustment bolt. Since the structure becomes simpler, it is easy to manufacture a mold for forming the nut member, and the manufacturing cost can be further reduced.
