Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a floor bundle which is placed under the floor of a building and is installed on a foundation such as a pile of stones and supports Daihiki.

[0002]

[Prior art]

 Conventionally, as a floor bundle for supporting Daihiki (floor beams) installed under the floor of detached houses, condominiums, warehouses, and other buildings on foundations such as slabs, stones, and solid foundations, , A wooden bundle made of wood was used. However, when adjusting the height of the floor to be flush with the above-mentioned wooden bundle, it is necessary to cut the timber according to the dimensions and further finely adjust the height of the floor using a wedge or the like. There was a problem that workability was extremely poor.

Therefore, recently, in place of the wooden bundle, a metal floor bundle as shown in FIG. 18 has been used. This floor bundle includes a support base 42 in which a first screw rod 41 is erected on a base plate 40, and a center of the lower surface of a horizontal piece 43a of an L-shaped plate 43 formed in a substantially L shape in a front view. A support portion 45 on which a second screw rod 44, which is threaded in the opposite direction to the first screw rod 41, is vertically installed, and a first screw rod 41 and a support portion 45 of the support base 42. It has a pipe-shaped turnbuckle portion 46 which is engaged with both of the two screw rods 44 and connects the two screw rods 41, 44. The L-shaped plate 43 of the support portion 45 and the base plate 40 of the support base 42 are provided with a plurality of nail holes 47, respectively. In this floor bundle, a support base 42 is installed on a foundation 48 such as a bundle stone, and a nail (not shown) is driven into a nail hole 47 of the base plate 40 to be fixed. On the other hand, the L-shaped plate 43 of the support portion 45 is attached to the large pull 49 so as to contact the horizontal piece 43a and the vertical piece 43b, respectively, and a nail (not shown) is driven into the nail hole 47. Fixed. Then, by rotating the turnbuckle portion 46 at the center, the support portion 45 is moved up and down to adjust the height of the hauling 49 so that the height of the floor is adjusted to be flush.

[0004]

[Problems to be solved by the device]

 However, in the above floor bundle, since the timber haul 49 is directly placed on the L-shaped plate 43 and fixed by nails, a predetermined accuracy is maintained at the beginning of construction, but if the timber dries over time. The so-called “slim” is generated in the Daihiki 49, and a small gap is formed between the Daihiki 49 and the L-shaped plate 43. Such a gap causes a creaking noise when walking on the floor. Further, since the nail is driven into the nail hole 47 of the L-shaped plate 43 and fixed to the large pull 49, the metal L-shaped plate 43 and the nail are directly contacted with each other, and the above-mentioned gap is formed. When vibration or the like is applied when a person walks, there is a problem that the L-shaped plate 43 and the nail rub against each other, and a louder squeak noise is generated.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a floor bundle in which squeaking noise is unlikely to occur even when the timber is dried and largely thinned.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the floor bundle of the present invention has a support base portion in which a first screw rod is erected on a base plate and a receiving plate and is threaded in the opposite direction to the first screw rod. The two screw rods are connected to each other by engaging both the support portion on which the second screw rod is hung, and the first screw rod of the support base portion and the second screw rod of the support portion. A floor bundle including a turnbuckle portion, wherein a plurality of nail holes are formed in the receiving plate, an elastic plate is laid on a receiving surface of the receiving plate, and the nail of the elastic plate is formed on the receiving plate. A fitting protrusion that fits inside the nail hole is integrally formed at a location corresponding to the hole, and a positioning hole for positioning a nail or the like is formed in the center of the fitting protrusion. And

Thus, in the floor bundle of the present invention, the elastic plate is laid on the receiving surface of the receiving plate. For this reason, when the receiving plate is nailed in a large amount, the elastic plate is sandwiched and fixed between them. Therefore, even if time has passed since the beginning of construction and the skin becomes thin, the elastic plate serves as a cushion, and a gap is less likely to be formed between the receiving plate and the Daihiki. Moreover, even if an adult walks on the floor, the vibration is absorbed by the cushion action, and the elastic plate also acts as a sliding plate between the haul and the receiving plate. As a result, the generation of squeak noise, which has been a problem in the past, can be significantly suppressed. Also, in the floor bundle of the present invention, a plurality of nail holes are formed in the receiving plate, and a fitting projection portion that fits in the nail hole is integrally formed at a portion of the elastic plate corresponding to the nail hole of the receiving plate. Is formed in a special manner, and a positioning hole for positioning a nail or the like is formed in the center of the fitting projection. Therefore, when the backing plate is attached by rough nailing, etc., the tip of the nail or the like is positioned in the positioning hole at the center of the fitting protrusion that fits in the nail hole, and is fitted along the positioning hole. A nail or the like penetrates the center of the collision part. Therefore, the nails do not come into direct contact with the inner surface of the nail hole of the receiving plate. This prevents the squeak noise caused by the direct rubbing of the metal between the nail and the backing plate.

In the floor bundle of the present invention, when it is formed in a plurality of divided vertical cracks with a gap of a predetermined width, or when the fitting protrusion formed on the elastic plate has a gap of a predetermined width. If there is a retaining protrusion that is formed in two parts of vertical cracks and that engages with the nail hole in a detachable manner on the outer periphery of the upper part of the fitting protrusion, the fitting formed on the elastic plate The joint projection is inserted into the nail hole while being deformed inward so as to narrow the gap of a predetermined width, and is detachably retained by the retainer projection. For this reason, the fitting protrusion is detachably fitted into the nail hole, and the elastic plate can be easily attached and detached, which improves workability. It is also possible to prepare different types of elastic plates and exchange them for different purposes. In addition, since the nail penetrates smoothly while widening the gap of the above-mentioned predetermined width during nailing, it is easy to nail and the workability is improved.

In the floor bundle of the present invention, the receiving plate is formed in an L-shape including a horizontal piece on which the second screw rod is vertically installed and a vertical piece standing from a side edge of the horizontal piece. If the vertical piece and the horizontal piece of the L-shaped receiving plate are each provided with a plurality of nail holes, the horizontal piece of the L-shaped receiving plate is nailed to the lower surface of the Daihiki. At the same time, an L-shaped vertical piece is nailed and fixed to the side surface of the Daihiki. For this reason, the fixation between the backing plate and the Daihiki becomes more complete, and even if “Rain” occurs in the Daihiki over time, the fixation between the backing plate and the Daihiki becomes less likely to loosen, and the squeak noise is further reduced. It has the effect of suppressing the occurrence.

In the floor bundle of the present invention, the nail holes formed in the horizontal piece are provided at four positions close to the square of the horizontal piece, and the nail holes formed in the vertical piece have the same height. If it is installed in two different places, the L-shaped backing plate is fastened to the four horizontal strips and two vertical strips with different heights. For this reason, the fixing of the backing plate to the Daihiki becomes more complete, and even if “Rain” occurs in the Daihiki over time, the fixing between the backing plate and the Daihiki becomes difficult to loosen, and the squeaking noise is further reduced. This has the effect of suppressing the generation.

In the floor bundle of the present invention, a trapezoidal raised portion is formed at the center of the upper surface of the base plate, and a first screw rod is erected at the center of the raised portion, and the raised portion is a flat surface. When it is formed to be horizontally long as viewed, the raised portion reinforces the mounting portion of the first screw rod of the base plate, and the floor bundle itself becomes strong. Particularly, since the raised portion is formed in a horizontally long shape in plan view, the strength of the base plate is further improved. Therefore, it is possible to prevent the accuracy from being deteriorated due to vibration or the like, and to suppress the generation of squeak noise. In addition, when an adhesive is applied to the lower surface of the base plate and adhesively fixed to the foundation, the adhesive accumulates in the space formed on the lower surface of the raised portion, which has the advantage of increasing the adhesive strength.

In the floor bundle of the present invention, a trapezoidal raised portion is formed at the center of the lower surface of the receiving plate, and a second screw rod is vertically provided at the center of the raised portion, and the raised portion has a bottom surface. When it is formed to be horizontally long in view, the raised portion reinforces the mounting portion of the second screw rod of the receiving plate, and the floor bundle itself becomes strong. Particularly, since the raised portion is formed in a horizontally long shape in bottom view, the strength of the receiving plate is further improved. Therefore, it is possible to prevent the accuracy from being deteriorated due to vibration or the like, and to suppress the generation of squeak noise.

In the floor bundle of the present invention, when the base plate is provided with a plurality of adhesive distribution holes and the anchor bolt insertion holes are provided, the adhesive is attached to the lower surface of the base plate. When the adhesive is applied and fixed on the foundation, the adhesive protrudes to the upper side through the adhesive distribution holes that have been distributed and drilled, and the protruding adhesive solidifies as it is. The bundle is firmly attached. Moreover, the anchor bolts are inserted through the anchor bolt insertion holes and mounted on the foundation, so that the fixing to the foundation is further strengthened. As a result, it is possible to prevent the accuracy from being fluctuated due to vibration or the like, and to suppress the generation of squeak noise. The adhesive flow hole and the anchor bolt insertion hole also have an air bleeding effect.

In the floor bundle of the present invention, when the predetermined portion at the center of the turnbuckle portion is formed into a hexagonal column shape, the hexagonal columnar portion of the turnbuckle portion grips the turnbuckle portion and rotates. It has the effect of improving the workability by providing a non-slip grip when making it work.

At this time, the adhesive is a through hole 10 for allowing the adhesive to circulate and to protrude to the upper side, and to solidify the protruding adhesive as it is to ensure fixing. Further, the two large-diameter holes formed are anchor bolt insertion holes 11 through which the anchor bolts are inserted when fixing the support base 3 by the anchor bolts provided on the foundation. The adhesive flow hole 10, the anchor bolt insertion hole 11, and the nail hole 9 also function as an air vent hole when applying the adhesive.

The support portion 6 is formed on the base plate 1 at the center of the lower surface of the horizontal piece 4a of the L-shaped plate 4 formed by bending a rectangular steel plate into an L shape, as shown in FIG. A trapezoidal raised portion 8 similar to that of the one is formed, and a second threaded rod 5 threaded into a right-hand screw is vertically provided at the center of the raised portion 8. The raised portion 8 is formed in a horizontally long shape in which both sides of the truncated cone are laterally extended in a bottom view. The horizontal piece 4a of the L-shaped plate 4 is provided with nail holes 9 at four positions near the square. Further, as shown in FIG. 5, the vertical piece 4b is provided with nail holes 9 at two different heights.

An L-shaped elastic plate 12 is laid on the L-shaped receiving surface of the L-shaped plate 4 (see FIG. 1). The elastic plate 12 is made of polyethylene resin, and is formed in a substantially rectangular shape as a whole, as shown in FIG. 6, and has a horizontal piece portion 13a corresponding to the horizontal piece 4a of the L-shaped plate 4 and the L-shaped plate 4. It is composed of a vertical piece portion 13b corresponding to the vertical piece 4b and a thin wall portion 13c which is bent corresponding to the bent portion of the L-shaped plate 4. The elastic plate 12 is formed with a fitting projection 14 that fits into the nail hole 9 at a location corresponding to the nail hole 9 of the L-shaped plate 4. As shown in FIGS. 7 and 8, the fitting protrusion 14 has a substantially cylindrical shape, and a positioning hole 15 for locating the tip of the nail penetrates through the center thereof, and a gap 16 of a predetermined width is formed in the center. It is formed, and is formed in two divided shapes of vertical cracks through the gap 16. Further, the upper part of the fitting projection 14 is formed in a hemispherical shape, and the outer periphery thereof is formed as a retaining projection 24 that is detachably engaged with the nail hole 9. Then, as shown in FIG. 9, the fitting protrusion 14 is detachably fitted into the nail hole 9 of the L-shaped plate 4, whereby the elastic plate 12 is laid on the receiving surface of the L-shaped plate 4. It is like this.

Here, when the elastic plate 12 is laid on the L-shaped plate 4, as shown in FIG. 10, the fitting protrusion 14 of the elastic plate 12 is inserted into the nail hole 9 opening of the L-shaped plate 4. After positioning, the fitting protrusion 14 is inserted into the nail hole 9. At this time, as shown in FIG. 11, the fitting protrusion 14 is deformed so that the central gap 16 is narrowed, and the tip passes through the inside of the nail hole 9. When the retaining projection 24 is engaged with the nail hole 9, the fitting protrusion 14 is fitted into the nail hole 9, and as shown in FIG. 12, the elastic plate 12 is an L-shaped plate. 4 is installed, and the support part 6 is formed.

The turnbuckle portion 7 is made of steel and formed in a pipe shape. The lower inner surface of the turnbuckle portion 7 is formed with a screw portion that engages with the first screw rod 2. The matching screw part is formed. The large-diameter portion 25 is formed in a hexagonal column shape while the central portion having a predetermined length is formed in a large diameter (see FIG. 1).

The floor bundle of the present invention, as shown in FIG. 13, supports the first screw rod 2 of the support base 3 with the lower end portion of the turnbuckle portion 7 and the nut 19, and supports them. The second screw rod 5 of the receiving portion 6 is assembled by fitting the upper end portion of the turnbuckle portion 7 and the nut 19 and connecting the both screw rods 2, 5.

In the above structure, the floor bundle can be used as follows. That is, as shown in FIG. 14, the support base portion 3 is fixed on the slab 17 and the support portion 6 is fixed on the pulling table 18. In this state, by rotating the turnbuckle portion 7, the support portion 6 is moved up and down by the screw action of the turnbuckle portion 7 engaged with the first and second screw rods 2 and 5. Has become.

The support 6 is fixed to the haul 18 as follows. First, as shown in FIG. 15, the floor bundle is turned upside down, and the large plate 18 is applied to both the vertical piece portion 13b and the horizontal piece portion 13a of the elastic plate 12 (not visible in the figure) of the L-shaped plate 4. Position them so that they touch. Then, as shown in FIG. 16, the tip of the nail 23 is positioned in the positioning hole 15 of the fitting projection 14 which is fitted into the nail hole 9 and exposed to the outside, and from this state, the above-mentioned nail 23 is removed. It is struck so that it penetrates along the inside of the positioning hole 15. At this time, the fitting protrusion 14 is deformed so that the gap 16 widens. Then, as shown in FIG. 17, the nail 23 penetrates and is driven into the haul 18 while deforming and crushing the fitting protrusion 14. As a result, when the L-shaped plate 4 is nailed to the haul 18 the elastic plate 12 is fixed in a sandwiched state (see FIG. 1). Further, the crushed fitting protrusion 14 is sandwiched between the nail 23 and the L-shaped plate 4, so that the nail 23 and the L-shaped plate 4 do not come into direct contact with each other and the support portion 6 is pulled up. It can be fixed to 18.

Further, the support base 3 is fixed to the pile 17 in the following manner. First, an adhesive is applied to the lower surface of the base plate 1. At this time, the adhesive accumulates in the space formed on the lower surface of the raised portion 8 formed on the base plate 1. Then, while the anchor bolts 21 erected on the stones 17 are inserted into the anchor bolt insertion holes 11 of the base plate 1, the support base 3 is positioned and placed on the stones 17. Next, a nut is attached to the anchor bolt 21. At this time, the adhesive 22 sticks out to the upper side through the adhesive flow holes 10 formed in the base plate 1 in a distributed manner, and the sticking adhesive 22 solidifies as it is (see FIG. 14). At this time, the adhesive flow hole 10, the anchor bolt insertion hole 11 and the nail hole 9 also have an air bleeding effect. After that, the nail 23 is struck by utilizing the nail hole 9 formed in the base plate 1 to fix the support base portion 3 to the bundle stone 17.

As described above, according to the floor bundle, when the L-shaped plate 4 is nailed to the large pull 18, the elastic plate 12 is fixed in a sandwiched state. Therefore, even if the pullout 18 becomes thin, the elastic plate 12 serves as a cushion, a gap is less likely to be formed between the L-shaped plate 4 and the pullout 18, vibration is absorbed, and squeak noise is generated. Is suppressed. Further, when the L-shaped plate 4 is attached to the large pull 18 by nailing, the tip of the nail 23 is positioned in the positioning hole 15 in the center of the fitting projection 14 fitted in the nail hole 9, and the positioning hole is formed. A nail 23 penetrates through the center of the fitting protrusion 14 along the line 15. Therefore, the nail 23 and the L-shaped plate 4 do not come into contact with each other, and the squeak noise caused by the direct rubbing of the metals is prevented.

In the above floor bundle, the elastic plate 12 is formed of polyethylene resin, but the invention is not limited to this, and various rubber materials such as natural rubber and synthetic rubber, urethane-based resin, and silicone-based resin can be used. Various materials such as various resin materials such as resin can be used.

Further, in the above-mentioned floor bundle, the fitting projection 14 formed on the elastic plate 12 is formed in a vertically split two-divided shape, but the present invention is not limited to this, and it is a three-divided or four-divided shape. It may be formed in any shape as long as it is in the form of a plurality of vertical cracks. Even in this case, the same operation and effect as described above can be obtained.

Further, in the above floor bundle, the nail 23 is used for fixing the L-shaped plate 4 and the haul 18 and the base plate 1 and the bundle 17, but the present invention is not limited to this. There is no problem even if a screw or the like is inserted through the plate 4 or the nail hole 9 of the base plate 1 and fixed by a screw or the like.
