And a spherical end 22 is formed on the lower end side of the support 2, and a recess storage body 31 is formed on the lower surface base 3 with the spherical end 22 of the support 2. And the flange 32 is formed, and the slit 33 in which the recess is expanded when the spherical end 22 is combined is continuously formed in the recess storage body 31 and the flange 32, and the diameter of the upper end side of the recess of the recess storage body Is made smaller than the diameter of the spherical portion of the spherical end, so that the spherical end 22 can be easily combined and fixed to the recess storage body 31.

When the slope-corresponding bundle described in Patent Document 1 is constructed, if the construction site is a smooth surface having a uniform surface, the entire bottom surface side of the lower surface base 3 uniformly contacts the construction site, causing a problem. There is no.
However, in the case of non-land where a concave portion and a convex portion exist in a part of a construction site, rattling is easily generated, and stable installation could not be performed.
In addition, the floor noise and the response to the earthquake were not sufficient.
Therefore, it is an object of the present invention to prevent the generation of rattling even when the construction site is uneven, and to stably install it, to prevent floor noise, and to have a seismic isolation function. It is in providing a point support bundle.

  The means for solving the problems of the present invention are as follows.

Each side of the three-point support plate is gently curved in a convex shape from the back side to the front side to an intermediate portion near the center.
The dome-shaped convex portion is a portion that protrudes in a dome shape on the surface side of the three-point support plate.
The spherical container can be formed near the top of the dome-like convex portion by welding or bonding with an adhesive.

The spherical end may be substantially spherical as a whole, or at least the lower half of the upper and lower halves may be spherical, that is, hemispherical.
When the spherical storage body is fitted in order to combine the spherical end portions, a part thereof is opened so as to be temporarily expanded, and can be tightened so that the spherical end portion is not pulled out by closing means such as a bolt. It is.

The spherical housing conforms to the shape of the spherical end of the support, and is obtained by cutting the upper portion of the hollow sphere horizontally above the hollow sphere.
The outer diameter of the spherical housing is equal to or slightly larger than the outer diameter of the spherical portion at the spherical end, and the diameter at the upper end side is smaller than the diameter of the spherical portion at the spherical end.

The projection-like portion protrudes downward from the back surface of the three-point support plate, and is formed so as to be in contact with the installation location in a point shape instead of a surface shape.
The dot shape in this case is not limited to a diameter of about several millimeters, and may be a circle of about 30 millimeters, preferably about 20 millimeters.

As the projection-like portion, it is preferable that the whole is projected in a small dome shape, and the tip portion is formed in a circular shape having a diameter of about 20 mm.
Such a projection-like portion can be formed, for example, by pushing out a flat three-point support plate from the opposite side with a predetermined convex member.

Here, since the triangular three-point support plate is provided, by arranging the protrusion-like parts at each corner, it becomes possible to arrange the three protrusion-like parts in an equilateral triangle shape.
And, by arranging the three projecting portions in an equilateral triangle shape, it becomes possible to support three points maintaining an even balance.
It is also possible to provide a hole of about 6 mm in diameter for inserting a concrete nail in the circular portion formed at the tip of the projection.

  Although it is desirable to form all of the components that make up the three-point support plate and the post from the metal such as steel, the above-mentioned non-land compatible three-point support bundle can also be made of a resin material having sufficient strength. .

  A slit may be formed in a part of the spherical housing, and two closing pieces for closing the slit may be formed on the outer surface of the spherical housing so as to sandwich the slit formation portion.

Here, a hole may be formed in the closing piece so that a bolt or the like as a closing means can be attached.
That is, in the state where the spherical end portion is combined with the spherical storage body, the support is formed so as not to easily come off, and the support is formed so as to be fixed by closing with a bolt or the like.

  According to the present invention, the following effects can be achieved.

  In the non-land compatible three-point support bundle of the present invention, three projections are arranged in an equilateral triangle on the side of the contact surface with the construction area, and the three projections are in contact with the construction area. Since the support combined with the three-point support plate can cope with inclination, rattling does not occur even if there is non-land in a part of the construction site, and stable installation is possible.

Also, in addition to the static load, a spherical storage body to which a dynamic load is applied is formed on the dome-like convex portion, and furthermore, since each side of the three-point support plate is curved toward the middle portion, Can be ideally transmitted as a pressing force concentrated on the protrusion.
Therefore, more stable installation becomes possible and contributes to the prevention of floor noise.
That is, in the floor material to be used, in addition to a certain static load, a dynamic load always occurs due to movement of a person, etc., which causes a ringing noise, so that stable floor installation It becomes possible to prevent a ringing effectively.

  Furthermore, when using a hole formed at the tip of the projection-like portion and fixing it to a setting surface with, for example, a concrete nail, different movements occur on the installation surface side and the floor material side in lateral shaking at the time of earthquake Even in the case of the above, the movement can be absorbed by the spherical end on the lower end side of the support and the spherical housing that is combined with the spherical end, and the seismic isolation function can be exhibited.

  Therefore, the three-point support bundle for non-landing of the present invention does not cause rattling even when the construction location is non-land, and can be stably installed, and also prevents floor noise and provides a seismic isolation function. Have.

  In addition, in the non-land compliant three-point support bundle of the present invention, the construction surface, which is a smooth surface in design, often has a partially projecting portion at the construction site, but the projecting portion is Not only can the space be provided by the protrusions, but also the clearance of the dome-like protrusions and the clearance of the curved portions toward the middle part of each side enables more stable installation.

It is explanatory drawing which decomposes | disassembles and shows the non-land corresponding three-point support bundle | flux of this invention. It is a figure which shows an example of the three-point support plate which comprises the non-land corresponding three-point support bundle of this invention, (a) is a top view, (b) is a side view, (c) is a longitudinal cross-sectional view. It is a figure which shows the use condition of the non-land corresponding three-point supporting bundle of this invention.

Hereinafter, an embodiment for carrying out the present invention will be specifically described with reference to the drawings.
Here, in the attached drawings, the same members are denoted by the same reference numerals, and redundant descriptions are omitted.
In addition, since this description is one form by which this invention is implemented, this invention is not limited to an applicable form.

  The landless three-point support bundle according to the present embodiment is used as a bundle for supporting a floor material at a construction site, and in the present embodiment, a steel plate is processed into a triangular shape, and a mold having a predetermined shape is formed. The three-point support plate 1 is manufactured by using and pressing.

  As shown in FIGS. 1 and 3, the non-land compatible three-point support bundle supports a floor material or the like by the three-point support plate 1 being engaged with a steel support 2.

The support 2 is composed of an upper support 22 on the upper end of which an upper base 21 supporting a floor material is attached, a hollow intermediate joint 23 having a screw formed inside, and a lower support 24.
Screws are formed on the upper support 22 and the lower support 24, and the overall height can be adjusted by adjusting the degree of screwing in combination with the intermediate joint 23.
On the lower end side of the lower support column 24, a spherical end 25 of a steel ball having a diameter of 20 mm is formed.

  The three-point support plate 1 to be engaged with the support 2 has a triangular shape as a whole, and a spherical storage body 11 to be engaged with the spherical end 25 of the support 2 is formed on the surface side.

The spherical storage body 11 is attached by welding to the top of the dome-shaped convex portion 12 as shown in (c) of FIG.
The spherical storage body 11 has a slit 11 a at one place in the longitudinal direction, and is formed so as to be temporarily expanded when the spherical end portions 25 are combined.
The spherical housing 11 conforms to the shape of the spherical end 25 of the column 2 and is formed so that the inside thereof cuts off the top of the hollow sphere horizontally.

The outer diameter of the spherical housing 11 is equal to or slightly larger than the outer diameter of the spherical portion of the spherical end 25, and the diameter of the upper end is smaller than the diameter of the spherical portion of the spherical end 25. .
For example, when the diameter of the spherical portion is 20.0 mm, the inner diameter of the upper end side of the spherical housing 11 is 19.3 mm.

The diameter on the upper end side of the spherical housing 11 indicates the length from one end of the inner diameter portion to the opposite end opposite to the other.
As described above, by forming the diameter of the upper end side of the spherical storage body 11 smaller than the diameter of the spherical portion of the spherical end 25, when the columns 2 are combined, the columns 2 become difficult to come off, and are held It is possible to increase the power.

In addition, on the outer surface of the spherical housing 11, two closing pieces 13 for closing the slit 11a are integrally formed so as to sandwich the portion where the slit 11a is formed.
Here, a hole 15 is formed in the closing piece 13 so that a bolt 14 or the like as a closing means can be attached.

As shown in (b) and (c) in FIG. 2, a flat surface having a circular tip as shown in (b) and (c) in FIG. The protruding portions 16 are formed respectively.
The protruding portions 16 project downward from the back surface of the three-point support plate 11.
Therefore, the contact between the projection-like portion 16 and the construction site is not planar but contact only at three points.
Although illustration is omitted, a convex portion or a concave portion may be provided on the three-point support plate 11 from the spherical storage body 11 located at the vertex of the three-point support plate 11 toward the projecting portion 16 formed at each corner. Strength can also be increased.

  The projection-like portion 16 in which the tip end portion is a circular flat surface is provided with a fixing hole 16 a for inserting a concrete nail into and fixing to a mounting surface.

Next, an example of use of the above-described non-land compatible three-point support bundle will be described.
The non-land compatible three-point support bundle can be used for construction of a wood deck and construction of floor materials for general houses and office buildings.

At the time of construction, the upper support 22 is screwed into the upper end side of the intermediate joint 23 in advance, and the lower support 24 is screwed into the lower end side to prepare the support 2.
The non-landing-compatible three-point support bundle is disposed at a predetermined location on the installation surface which is a construction location.

Here, in the non-land compliant three-point support bundle, each projection 16 of the triangular three-point support plate 1 contacts the installation location and the three points of the triangular shape in a well-balanced manner, and the spherical end 25 and the spherical end As the storage unit 11 is combined to be freely inclined, it can be stably installed even if there is unevenness due to the concave portion or the convex portion in a part of the construction site.
That is, even if only one point is in contact with the convex portion among the three points in contact, even if the heights are different, it is possible to cope with the inclination, so that the load can be received in a balanced manner at three points. It is possible to make the columns 2 vertical while the point support plate 1 is inclined.
Moreover, not only the space by the protrusion 16 can cope with the non-land due to the protrusion, but also the clearance of the dome-like protrusion and the clearance by the curved portion to the middle part of each side can be coped with. Stable installation is possible.

After placement, the spherical end 25 of the lower column 24 of column 2 is combined with the spherical enclosure 11 of the three-point support plate 1.
At the time of combination, the space by the slits 11a temporarily expands.
Therefore, the combination of the spherical end 25 with the spherical container 1 can be easily performed.

Then, after the vertical position of the column 2 and the desired height adjustment are accurately made, the bolt 14 inserted into the hole 15 of the closing piece 13 is fixed by tightening tightly using a nut (not shown).
Here, in the combined state, the diameter of the upper end side of the spherical storage body 11 is slightly smaller than the diameter of the spherical end 25, so that it is possible to adjust the inclination angle while enhancing the retention force with the support 2 difficult to be removed.

When the installation is completed, it can be fixed by driving in an anchor bolt from the hole of the projection 16.
The spherical end portion 25 of the lower end side of the column 2 and the spherical storage body 11 which is combined with the spherical end portion 25 even when the installation surface side and the floor material side move differently due to the fixation due to the fixing. Can absorb the movement and can exhibit a seismic isolation function.

Further, in addition to the static load, the spherical storage body 11 to which the dynamic load is applied is formed on the dome-like convex portion 12, and furthermore, since each side of the three-point support plate 1 is curved toward the middle portion The load after the installation can be ideally transmitted as a force that focuses on the protruding portion 16.
Therefore, more stable installation becomes possible and contributes to the prevention of floor noise.
That is, in the floor material to be used, in addition to a certain static load, a dynamic load always occurs due to movement of a person, etc., which causes a ringing noise, so that stable floor installation It becomes possible to prevent a ringing effectively.

The non-land compatible three-point support bundle exerts the effect that the stability is excellent even when the construction site is non-land, but of course, it can be used even if the construction site is a smooth surface.
Further, as shown in FIG. 3, the non-land compatible three-point support bundle can be used also for a construction site where the whole is inclined.
