Description

  The present invention relates to a base foundation spacer capable of height adjustment, which is used when a foundation is horizontally arranged on the top end face of a foundation (cloth foundation) constructed for a wooden house by taking a clearance for ventilation from the top end face. About.

In the structure of a wooden house, the foundation is installed on the top edge of the foundation. At this time, a member called a spacer may be interposed between the base and the base top end surface for underfloor ventilation.
At this time, even if the foundation work is done with great care, undulating irregularities occur on the top surface of the foundation, and simply placing a spacer and placing the foundation on it will cause a gap between the foundation and the spacer. Yes, the foundation cannot be supported evenly. For this reason, the plate-shaped spacer is divided into wedge-shaped upper and lower pieces when viewed from the thickness direction, and the upper and lower pieces are shifted in the wedge direction (left and right) to adjust the thickness (Cited document 1), or separately prepared. The overall height is adjusted by adding a thin adjustment plate.

Japanese Patent Laid-Open No. 2001-311160

As seen in the prior art, in the structure in which the plate-shaped spacer is divided into two wedge-shaped upper and lower pieces when viewed from the thickness direction, and the thickness is adjusted by shifting the upper and lower pieces in the wedge direction, the upper and lower pieces are shifted left and right. If it is attempted to achieve a predetermined adjustment height by reducing the amount, the angle of inclination of the surface where the upper and lower pieces are superposed (the mating surface and the receiving surface) becomes large, and the superposition surface becomes slippery due to pressure from above. . Conversely, when the inclination angle is reduced, the amount of shifting the upper and lower pieces to the left and right is increased to achieve the predetermined adjustment height, and the substantial overlapping portion (substantially overlapping portion where the upper and lower pieces are present in the vertical direction) with respect to the entire length. A ratio becomes small and the substantial installation area which supports the load from upper direction becomes small. For this reason, an unnecessarily long spacer is required.
In addition, as for the installation area, in the case of the second floor building specification, a width of 100 mm × the horizontal dimension of 150 mm or more is standard, and in the case of the third floor building specification, the width of 100 mm × the horizontal dimension of 180 mm is standard. A width of 100 mm is a standard width dimension as a spacer. The horizontal dimension means the length of the spacer.

  Thus, the present invention uses a wedge-shaped height adjustment structure, but halves the amount of shifting necessary to achieve a predetermined adjustment height and provides a sufficient installation area as a relatively small spacer. It is an object of the present invention to provide a foundation foundation spacer capable of height adjustment and a foundation foundation spacer capable of height adjustment that has the same technical idea, but eliminates slippage due to an inclined surface.

  The base foundation spacer is formed by superposing three wedge-shaped members, and the height is adjusted by shifting the intermediate member to the left and right with respect to the upper and lower members. The overlapping surface between the three members may be a combination of horizontal step surfaces.

Since three wedge-shaped members are used, the amount of shift in the left-right direction (corresponding to the longitudinal direction of the base or its orthogonal direction) with respect to the adjustment height is halved. Thereby, it is easy to achieve the required installation area.
By combining the overlapping surfaces between the three members with a horizontal staircase surface, there is no urging in the left-right direction due to a load from above, and the foundation is supported by a foundation foundation spacer that can be adjusted in height. Stabilize.

  Combine two wedge-shaped A members and one wedge-shaped B member. The A member is a plate-like body having a front surface as a support surface and a back surface as a mating surface, and when viewed from the thickness direction, the support surface is horizontal, and the mating surface is tilted from one to the other in the left-right direction at a certain angle Form. The B member has both a front surface and a rear surface as viewed from the thickness direction, and the receiving surface is a surface inclined at the same constant angle as the mating surface of the A member. And Two A members are arranged facing each other with their mating surfaces facing inward. The B member is disposed in the space between the A members. At this time, the mating surfaces of the A member and the receiving surface of the B member are arranged so as to be aligned, and polymerization is performed integrally.

The inclination of the mating surface and the receiving surface is such that when the total height of the substantially overlapped portions of the A member and the B member is the minimum use size or the maximum use size, the left and right dimension of the substantially overlap portion is 150 mm or more (2nd floor Building specifications) or 180 mm or more (third-floor building specifications).
Alternatively, the length of the B member in the left-right direction may be sufficiently large with respect to the A member so that the substantially overlapped portion of the A member and the B member is always the length of the A member.
Similarly, the A member and the B member may divide the mating surface and the receiving surface into a plurality of step surfaces that are equally spaced in the left-right direction. Each staircase is horizontal. Further, a straight line connecting the centers of the respective step surfaces as viewed from the thickness direction may be inclined at the predetermined angle with respect to the horizontal.
In order to prevent the A member and the B material from shifting sideways, a dowel is provided on one of the mating surface and the receiving surface, and a recess in which the dowel is fitted on the other, or a protrusion and a groove between the A member and the B member. An anti-slip may be provided by providing a fitting structure.

FIG. 1 shows a base foundation spacer 1 (hereinafter referred to as spacer 1) capable of height adjustment, in which one A member and two B members are superposed. These are molded from hard recycled rubber. The direction of arrow A is the left-right direction, and each has an opening 2 for inserting an anchor bolt at the center. The broken line is the anchor bolt 3 and shows only the upper part. Reference numeral 4 denotes a cut groove having a V-shaped cross section, which also serves as a scale by adding numerals.
As shown in FIG. 2, the spacer 1 is arranged on the top end surface of the constructed fabric base 5 at an interval of 910 mm, and a base 6 that supports the pillar 14 is installed thereon. In the arrangement of 910 mm intervals, the spacer 1 may be the position of the anchor bolt 3 for fixing the base 6 to the cloth foundation 5. In this case, the anchor bolt 3 is inserted through the opening 2 formed in the A member and the B member. Note that the spacer 1 is also used immediately below the portion where the pillar 14 of the base 6 is erected. In this case, since the hole down hardware for tightening the pillar 14 and the base 6 and the anchor bolt 3 for fixing the base 6 to the foundation are often arranged close to the pillar 14, the opening 2 is essential for the spacer 1. is there.

3 to 4 show the spacer 1 as the first embodiment more specifically. FIG. 3 is before height (thickness) adjustment, and both ends of the polymerized A and B members are aligned. At this time, the total length of the spacer 1 is 280 mm (referred to as the original length), the height is 20 mm (referred to as the original height), and the width is 100 mm.
That is, the A member is a plate-like body having the support surface 7 on the front surface and the mating surface 8 (FIG. 4), and the support surface 7 is horizontal and the mating surface 8 has a certain angle when viewed from the thickness direction. The wedge shape is slanted from one to the other in the longitudinal direction. The base end (the end where the thickness is large) of the A member is 10 mm high.
The B member is a plate-shaped body having both surfaces as receiving surfaces 9 and has a wedge shape in which the receiving surface 9 is inclined from one side to the other in the longitudinal direction at the same constant angle as the mating surface 8 of the A member when viewed from the thickness direction. . The base end of the B member has a height of 20 mm.

When two A members are aligned at both ends and the mating surface 8 faces inward, the arrangement is symmetrical, and the B member can be superposed between the A members with the B member interposed therebetween. The state where the base end of the A member and the sharp end of the B member are aligned is the “original state” in which the height is not adjusted, and the base end of the two A members and the base end of the B member are the spacers 1. It becomes both ends.
The A member and the B member are assumed to be composed of 20 compartments 10 (round numbers 1 from the base end side) with equal intervals in the entire length, and one compartment is set to 14 mm. For this reason, both the A member and the B member have a total length of 280 mm. Further, when the central B member is inserted (shifted) in the direction of the arrow B by 14 mm (one section) with respect to the upper and lower A members, the height of the spacer 1 is increased by 1 mm, and when pulled out, it is decreased by 1 mm. In this way, the height of the spacer 1 is adjusted. The scale 4 in FIG. 1 shows this situation, and the position indicated by the base end of the B member with respect to the scale 4 of the A member is the height of the entire spacer 1 at that time. Hereinafter, the height adjustment will be described in units of 1 mm. Actually, since the inclined surfaces are continuous, adjustment can be performed in arbitrary units.
However, since the spacer 1 needs to support the base 6 stably, in the case of a two-story building specification, a substantial overlap portion of 154 mm in length on the support surface 7 (overlap of two A members and B members in the height direction) There is a part). Therefore, the maximum useable dimension that can be set in the first embodiment is 29.00 mm (adjustment amount 9 mm) as shown in FIG. The inclination of the mating surface 8 and the receiving surface 9 at this time is tan (1/14) from the front end side of the wedge. The minimum use dimension is 11 mm (adjustment amount 9 mm) as shown in FIG. In this case, since the height of the circled numbers 1-9 of the A member exceeds 5.5 mm, and the height of the B member of the circled members 1-9 exceeds 11 mm, it is not necessary. Because it cannot be used, it will be excised. The cut groove 4 is used for excision.
In the case of the 3 floor building specification, since a substantially overlapped portion having a length of 182 mm is left on the support surface 7, the maximum usable dimension that can be set is 27.00 mm (adjustment amount 7 mm), and the minimum usable dimension is 13.00 mm. (Adjustment amount 7 mm).

To summarize the dimensional relationship,
a ... original height b ... original lateral dimension c ... length of one section (amount of movement necessary to obtain an adjustment height of 1 mm)
d: Height after adjustment x: Movement amount
(However, for the 2nd floor building specification x <b-154
3rd floor building specification x <b-182)

When increasing a + x / c = d
When lowering a−x / c = d

FIG. 6 shows a second embodiment in which one section is 12 mm. Therefore, the overall length is 240 mm, which is shorter than that of the first embodiment and is formed compact. The inclination of the mating surface 8 and the receiving surface 9 is tan 1/12, and the inclination becomes large. FIG. 7 shows an example in which the height is adjusted.
In this case, in the 2nd floor building specification (installation area 100 × 156mm),
Minimum use size 13mm
Maximum use size 27mm
In the 3rd floor building specification (installation area 100 x 180mm),
Minimum use size 15mm
Maximum use size 25mm
It is.

FIG. 8 shows a third embodiment. Contrary to the first embodiment, when the length of one section is 16 mm, the total length is 320 mm, but the inclination is small. The inclination of the mating surface 8 and the receiving surface 9 is tan 1/16.
In this case, in the 2nd floor building specification (installation area 100 x 160 mm),
Minimum use size 10mm
Maximum use size 30mm
In the 3rd floor building specification (installation area 100 x 192mm),
Minimum use size 12mm
Maximum use size 28mm
It is.

  Thus, although the length in the left-right direction increases as the length of one section increases, the maximum usable dimension can be increased. Further, the inclination of the mating surface 8 and the receiving surface 9 is reduced, and the tendency that the A member and the B member are shifted in the left-right direction due to a load from above is reduced and stabilized. The original height (a), the original horizontal dimension (b), and the length of one section can be determined as appropriate. However, the degree taken as an example is appropriate.

The spacer 1 is used as follows.
The place where the spacer 1 is installed on the top end surface of the completed fabric foundation 5 is determined with a 910 mm interval as a standard. Next, the height of the top end surface of each of the portions is measured by level. The measurement is to calculate the excess or deficiency from the set standard height (bottom surface position of the base 6). The obtained excess or deficiency is written on the top end surface for the time being, and the height of the spacer 1 is sequentially increased. It adjusts according to the excess and deficiency, and it fixes so that the movement of the left-right direction may not arise between A member and B member. Next, the base 6 is placed on these spacers 1. In Examples 1-3, the excess / deficiency height of about 0-10 mm can be adjusted, ensuring a required installation area.

  As a means for preventing movement in the left-right direction between the A member and the B member, as shown in FIG. 9, the A member mating surface 8 is finely divided into the A member mating surface 8 and the B member receiving surface 9. It is good also as a structure which provides the parallel ridge 11 and meshes this. Further, in order to prevent the displacement in the width direction, in this example, a protrusion 15 parallel to the mating surface 8 of the A member is formed in the left-right direction, while a concave groove 16 for receiving this is formed on the receiving surface 9 of the B member. It is formed and has a fitting structure that fits when the A member and the B member are superposed.

  FIGS. 10 to 13 show the fourth embodiment, and the A member and the B member similarly define the mating surface 8 and the receiving surface 9 by a plurality of step surfaces equally spaced in the longitudinal direction. Each staircase surface is horizontal, and a straight line connecting the centers of the staircase surfaces when viewed from the thickness direction is inclined at a certain angle with respect to the horizontal. In this embodiment, the base end of the A member is 8 mm in height and the tip is 2 mm in height. If one step surface is defined as one section 10, the total length is 252 mm in seven sections by one section 36 mm. The B member has a base end height of 16 mm and a tip end height of 2 mm, and has eight sections and a total length of 288 mm. The slope is tan 1/36.

Therefore, when the B member is disposed between the two A members and the tip of the A member is aligned with the base end of the B member as shown in FIG. 10, the spacer 1 has a total height of 20 mm and a total length of 288 mm. (FIG. 11a).
Reference numeral 12 is a dowel and reference numeral 13 is a dowel hole. In a front view such as FIG. 11, these are schematically illustrated for easy understanding. In the A member, as shown in FIG. 12, one member is arranged on each side of each section 10 on the mating surface 8 and is alternately arranged between adjacent sections. In the B member, as shown in FIG. 13, only two dowel holes 13 are formed in the receiving surfaces 9 on both sides corresponding to the dowels 12 and the dowel holes 13 of the A member.

As shown in FIG. 11B, the spacer 1 is adjusted in such a way that the B member is inserted between the A members so as to increase the overall height, and the B member is pulled out as shown in FIG. There are cases where it is used with a smaller size. In any case, the adjustment is a unit of the section 10 (height adjustment amount 1 mm / movement amount 36 mm).
As shown in FIG. 11A, when the spacer 1 is used without height adjustment, the eighth section 10 from the base end of the B member is unnecessary and may be removed by cutting it off. As shown in FIG. 11B, when the spacer 1 is used with a high adjustment, as shown by the broken lines b and c, the tip side of the A member and the B member should be cut out and used compactly as a substantial overlapping portion. You can also. Further, when drawing out, as shown by a broken line d in FIG. 11C, it is necessary to excise the base end side section of the A member or to cut out the base end side section of the B member together with the base end side section of the A member. . For this reason, the cut groove | channel 4 parallel to the width direction is given so that excision may be easy.

Thus, when adjusting in the high direction, if the portion that protrudes to the left and right from the substantially overlapped portion is cut off, the intermediate B member is formed to be sufficiently large in the left and right direction, Until the total height of the substantially overlapped portion of the B member reaches the set maximum use size, the left and right dimension of the substantially overlapped portion is always set to the left and right dimension of the A member. The area (installation area) substantially in contact with the end face or the base 6 can be maintained constant.
In the fifth embodiment, five or more sections are required as the substantial polymerization portion, and the maximum use height is 24 mm.
In the fifth embodiment, the mating surface 8 and the receiving surface 9 overlap with each other between the horizontal step surfaces, and no component force in the left-right direction is generated between the A member and the B member due to the load from above. For this reason, the spacer 1 is not easily displaced, and the support state of the base is more stable.

  As mentioned above, although the Example was described, the material of A member and B member is not restricted to a rubber type | system | group, The material which has a weather resistance and has elasticity like a timber can be employ | adopted.
