Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal floor bundle fixed under a floor of a detached house or the like, on a slab, a solid foundation, or the like, and supporting a large scale.

[0002]

2. Description of the Related Art Heretofore, wooden bundles have been used as bundles for supporting large rooms under the floor of a building such as a detached house. Such a wooden bundle measures the height from the foundation to the skid, transports the wood to the cutting place, cuts it according to the above measurement dimensions, and installs the wood of this predetermined size on the foundation to pull the skid. The receiving is done. In many cases, the above series of operations are performed by a plurality of workers, and height measurement and cutting and mounting of wood are performed by different workers, and the mounting location is often mistaken. In such a case, in order to adjust the height of the bundle to a large height, wood cut into a wedge shape is driven into the gap.

[0003] In the above-mentioned wooden bundle, the work of cutting wood to a predetermined size and the work of adjusting the height with a wedge are extremely complicated. In addition, the wood is apt to warp due to water absorption or drying, and is likely to be deformed by a load. In addition, since the scrap material is mainly used for the bundle material, the material is also different, and there is a problem in accuracy in that the deformation and the irregularity are different depending on the material.

Therefore, recently, steel floor bundles have been used instead of wooden bundles. As shown in FIG. 9, the steel bundle includes a support plate 11 that supports the pulling pulley 10 and a base plate 13 that is fixed to a slab stone 12 or a concrete foundation. A screw rod 14 is vertically provided on the lower surface of the support plate 11, and
A screw rod 15 is erected on the upper surface of the base plate 13, and the two screw rods 14, 15 are connected by a turnbuckle 16. The height of the steel bundle is adjusted by rotating the turnbuckle 16 to raise and lower the support plate 11. According to such a steel bundle,
The work period can be shortened by shortening the work time, and "post-adjustment" for adjusting to large dimensional changes is easy, and the problem of accuracy is solved.

[0005]

In the above-mentioned floor bundle, a screw rod 14 suspended from a support plate 11 and a base plate 13 are provided.
Since the screw rods 15 erected on the floor bundle are connected by the turnbuckle part 16, the floor bundle itself needs to have a certain height or more. On the other hand, recent houses are often designed to make effective use of land with a small area as much as possible, and three-story houses and houses having rooms on a garage are increasing. In such a case, the height under the floor is 60-
It was very low, about 100 mm, and the conventional floor bundle could not be used because the height was too high.

Therefore, in the case of a low-floor building as described above, it is practiced to hand the timber horizontally and to bundle the timber as a bundle and put a floor thereon. As described above, low-floor buildings still use wooden bundles, and the problem of deterioration due to decay and mess due to warpage remains. Moreover, in the low-floor building as described above, the space under the floor is extremely narrow, so that there is a problem that once the decay or disorder occurs, the maintenance becomes extremely difficult, which is practically impossible. Therefore, plastic bundles are sometimes used.However, plastic bundles are insufficient in strength and cannot withstand heavy load. There is a problem that the floor must be peeled off and a new plastic bundle must be mounted again. In addition, in the low-floor building, since the underfloor space is narrow, abnormal sounds under the floor are likely to resonate in the room, and the floor bundle used here is required to have extremely low floor noise.

Further, in the construction of apartment buildings and the like, if a floor material is directly put on concrete, there is a problem that an old man and a child are liable to fracture, and a cold in winter is also a problem. In addition, pipes and wires are installed under the floor, and floors are spread using a bundle of square timber or a plastic bundle similar to the above-described low-floor building due to demands for soundproofing. In such a case, when a room or the like is built on a concrete slab or the like, moisture tends to be trapped particularly under the floor, and the above-mentioned decay or disorder is a serious problem. In addition, since apartments are condominiums, problems such as floor noise and soundproofing were particularly serious. Under these circumstances, there has been a strong demand for the development of a floor bundle that is easy to adjust in height and has good maintainability in low-floor buildings, etc., but to date, all such requirements have been satisfied. The fact is that floor bundles were not provided.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a metal floor bundle that is easy to adjust in height in a low-floor building, is robust, and has good maintainability.

[0009]

In order to achieve the above-mentioned object, a metal floor bundle according to the present invention has a base portion on which a screw rod is erected, and is fitted to the screw bar of the base portion. A support member attached to an upper end of the support member to support the floor member, wherein the support member is rotatably mounted on the support portion, and a screw is mounted on an upper portion of the support member. Part is formed,
A first point is that a fixing nut for fixing the support portion is fitted to the screw portion.

[0010] The metal floor bundle of the present invention comprises: a support portion on which a screw rod is vertically suspended to support a floor member; a support member fitted to the screw bar of the support portion; A base member attached to a lower end of the support member, a support member is rotatably mounted on the support portion, and a screw portion is formed on a lower side of the support member. A second point is that a fixing nut for fixing the portion is engaged.

That is, the first metal floor bundle of the present invention comprises:
A support member is rotatably attached to the support portion, a screw portion is formed on an upper portion of the support member, and a fixing nut for fixing the support portion is engaged with the screw portion. Further, in the second metal floor bundle of the present invention, the column member is rotatably attached to the support portion, a screw portion is formed on a lower portion of the column member, and the base portion is formed on the screw portion. A fixing nut for fixing the nut is engaged. Thus, like a conventional floor bundle, 2
Instead of connecting the two screw rods with the turnbuckle part,
Since the structure is such that the support member is directly attached to the support portion or the base portion, the height of the floor bundle itself can be reduced, and it can be used for low floor construction. Therefore, since problems such as deterioration due to decay and warpage due to warping as in the case of a bundle of conventional timber are almost eliminated, the present invention is extremely effective in low-floor buildings and condominiums where the space under the floor is narrow and maintenance is difficult. Furthermore, it is extremely rugged compared to plastic bundles, can withstand upward warpage such as heavy pulling, and can be easily adjusted in the event of warpage or misalignment. Absent. In addition, fine adjustment of the height is easier than the conventional product.

In the metal floor bundle according to the present invention, a plurality of nail holes are formed in the support portion, and an elastic plate is laid on a support surface of the support portion. In a case where a fitting projection for fitting into the nail hole is integrally formed at a location corresponding to the nail hole, and a positioning hole for positioning a nail or the like is formed in the center of the fitting projection. When the support portion is nailed to the floor member, the support member is fixed with the elastic plate sandwiched therebetween. Therefore, even if “fatness” occurs in the floor member after a lapse of time from the beginning of construction, the elastic plate serves as a cushion, and a gap is less likely to be formed between the support portion and the floor member. In addition, even when an adult walks on the floor, the vibration is absorbed by the cushioning effect, and the elastic plate also acts as a sliding plate between the floor member and the support portion, generating a squeaking sound. Is greatly reduced. Further, when the support portion is attached to the floor member by nailing or the like, the tip of the nail or the like is positioned in a positioning hole at the center of the fitting protrusion fitted into the nail hole, and the fitting protrusion is formed along the positioning hole. A nail or the like penetrates the center of the part. Therefore, the nail and the like do not come into direct contact with the inner surface of the nail hole of the support portion, and the squeak noise caused by the metal of the nail and the support portion directly rubbing against each other is prevented.
As described above, the underfloor noise and the floor noise are extremely small, and the present invention is extremely effective in a low-floor building, an apartment house, a condominium, and the like having a small underfloor space.

[0013]

Next, embodiments of the present invention will be described in detail.

1 to 5 show an embodiment of a metal floor bundle according to the present invention. This includes a base portion 1 on which a screw rod 2 is erected, an L-shaped plate (support portion) 4 formed in an L-shape in a front view, and a column member 7 engaging with the screw rod 2. And In the figure, reference numeral 19 denotes a nut which is fastened in a state where the support member 7 and the threaded rod 2 are engaged with each other to prevent loosening.

The raised portion 8 is formed in a horizontally long shape in which both sides of the truncated cone each extend in the horizontal direction in plan view.

The base 1 is provided with a plurality of holes having different diameters. Among these, eight small-diameter holes distributed and formed in the peripheral portion of the base 1 are nail holes 9 for fixing the base 1 to a slab or the like by nailing. In addition, six medium-diameter holes, which are distributed and drilled slightly inward from the nail holes 9, are provided by applying an adhesive to the lower surface of the base 1 and bonding the base 3 to the base. In this case, the adhesive is circulated and protrudes to the upper side, and the protruding adhesive is solidified as it is to secure the adhesive flow hole 5. Furthermore, when fixing the base part 1 with the anchor bolt provided on the base,
An anchor bolt insertion hole 6 through which the anchor bolt is inserted. The adhesive flow holes 5, anchor bolt insertion holes 6, and nail holes 9 also function as air vent holes for applying the adhesive and holes for drying the adhesive.

The L-shaped plate 4 is made of a rectangular steel plate.
At the center of the lower surface of the horizontal piece 4a of the L-shaped plate 4 bent and formed in a letter shape, a trapezoidal ridge 8 similar to that formed on the base 1 is formed. Nail holes 9 are formed in the horizontal piece 4a of the L-shaped plate 4 at four positions near the square. In the vertical piece 4b, nail holes 9 are formed at two places having different heights.

An L-shaped elastic plate 18 is also laid on the L-shaped receiving surface of the L-shaped plate 4. The elastic plate 18 is made of polyethylene resin, is formed in a substantially rectangular shape as a whole, and has a horizontal piece 18a corresponding to the horizontal piece 4a of the L-shaped plate 4 and a vertical piece corresponding to the vertical piece 4b of the L-shaped plate 4. It comprises a portion 18b and a thin portion 18c that is bent corresponding to the bent portion of the L-shaped plate 4. Then, as shown in FIG.
A fitting projection 20 that fits into the nail hole 9 is formed at a location corresponding to the nail hole 9 of the shaped plate 4.

The fitting projection 20 has a substantially cylindrical shape, and a positioning hole 21 for positioning the tip of the nail penetrates the center, and a gap having a predetermined width is formed in the center. It is formed in two parts. The upper part of the fitting projection 20 is formed in a hemispherical shape, and its outer periphery is formed as a retaining projection which engages with the nail hole 9 in a detachable manner. The fitting projection 20 is detachably fitted in the nail hole 9 of the L-shaped plate 4, whereby the elastic plate 8 is laid on the receiving surface of the L-shaped plate 4.

The column member 7 is made of steel and formed in a hexagonal pipe shape, and has an inner threaded portion 26 engaging with the threaded rod 2 on its inner surface.
Are formed. A circumferential groove 22 is formed on the outer periphery of the upper end, and a fitting hole 23 formed in the raised portion 8 of the L-shaped plate 4 is rotatably fitted in the circumferential groove 22. And the screw part 24 is formed in the outer peripheral surface of the upper part,
A fixing nut 25 for fixing the L-shaped plate 4 is engaged with the screw portion 24.

In the above configuration, the metal floor bundle can be used, for example, as follows. That is, as shown in FIG. 7, the base 1 is fixed on a concrete foundation or a slab, and the L-shaped plate 4 is fixed on a large or joist (floor member) 10. In this state, by rotating the support member 7, the support member 7 is rotatably attached to the L-shaped plate 4, and the L-shaped plate 4 moves up and down by the screw action of the support member 7 engaged with the screw rod 2. The floor height is adjusted. The L-shaped plate 4 is fixed by tightening the fixing nut 25 to the L-shaped plate 4 with the L-shaped plate 4 set at a predetermined height. Further, by tightening the nut 19 to the support member 7, the rotation of the support member 7 is prevented.

Here, the L-shaped plate 4 is fixed to the pulley 10 in the following manner. First, the metal floor bundle is turned upside down, and the L-shaped plate 4 is positioned so that the large pull 10 comes into contact with both the vertical piece 18 b and the horizontal piece 18 a of the elastic plate 18. Next, the tip of the nail is positioned in the positioning hole 21 of the fitting projection 20 that is fitted to the nail hole 9 and exposed to the outside, and from that state, the nail is hit so as to penetrate along the positioning hole 21. . And
While deforming and crushing the fitting projection 20,
The nail penetrates and is driven into pulling 10. This allows
When the L-shaped plate 4 is nailed to the pulling bar 10, the elastic plate 18 is fixed while being sandwiched (see FIG. 1). Further, the fitting projection 20 crushed between the nail and the L-shaped plate 4 is sandwiched between the nail and the L-shaped plate 4.
Can be fixed without directly contacting with.

The fixing of the base 1 to the slab 12 is performed, for example, as follows. First, an adhesive is applied to the lower surface of the base unit 1 and the base unit 1 is bonded to the upper surface of the bracelet 12. At this time, the adhesive protrudes upward through the adhesive flow holes 5 distributed and formed in the base portion 1, and the protruding adhesive is solidified as it is, and is firmly fixed by the anchor effect. At this time, the adhesive flow hole 5, the anchor bolt insertion hole 6, and the nail hole 9 also have an air releasing effect. After that, nails are beaten using the nail holes 9 formed in the base 1 to fix the base 1 to the slab 12.

As described above, according to the metal floor bundle, since the strut member 7 is directly attached to the L-shaped plate 4, the height of the floor bundle itself can be reduced, and a low-floor building is constructed. Can be used for Therefore, the problem of deterioration due to decay and warping due to warping such as conventional bundles of square timber or plastic bundles is almost eliminated, and this is effective in low-floor buildings and condominiums where the space under the floor is small and maintenance is difficult.

Further, when the L-shaped plate 4 is nailed to the pulley 10, the elastic plate 18 is fixed with the elastic plate 18 sandwiched therebetween. Therefore, even if "slender" occurs in the pulling pulley 10, the elastic plate 18 serves as a cushion, making it difficult for a gap to be formed between the L-shaped plate 4 and the pulling pulley 10, and absorbing vibration and generating squeak noise. Is suppressed. In addition, when the L-shaped plate 4 is attached to the pulley 10 by nailing, the positioning hole 21 at the center of the fitting projection 20 fitted in the nail hole 9 is provided.
The tip of the nail is positioned, and the nail penetrates the center of the fitting projection 20 along the positioning hole 21. Therefore,
The nail and the L-shaped plate 4 do not come into contact with each other, and squeak noise caused by direct rubbing between metals is prevented.

FIG. 8 shows a second embodiment of the metal floor bundle of the present invention. This consists of an L-shaped plate 4 and a base 1
