A gap is created between the floor panel 3 and the floor panel 3 as shown in FIG. 16 (B).
Floor ringing occurs when a load G is applied to 0. For example,
A collision sound is generated between the joists 30b and the Daihiki 31. Further, the joist 30b of the floor panel 30 is in direct contact with the Daihiki 31 and is fixed by the fastener 32. However, the joist 30b and the Daihaku 31 are dried and contracted, and are fixed by screws or the like due to repeated load. When the holding force of the tool 32 is reduced, when the load G is applied, shearing displacement occurs in the joint surface, and rubbing noise is generated.

Further, when the wooden joists 30b of the floor panel 30 dry and shrink, the screws 32 that cannot follow the movement loosen from the state of FIG. 17 (A) as shown in FIG. 17 (B), and the floor panel 30 and the large pull 31. Since there is a gap between and, floor ringing also occurs due to such a cause. Also, Daihiki 31
If the wood is made of wood, there is a problem that it is greatly deformed due to warping, twisting, etc. during drying shrinkage, lacks dimensional stability, and adversely affects workability.

An object of the present invention is to provide a floor squeal preventing floor structure using steel pulling steel which has good dimensional stability and workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. This floor squealing floor structure using a steel bar pull is a substantially square floor panel in which a plurality of steel bar pulls 1 are provided in parallel with a module width W of a building and one side has substantially the same size as the module width W. Both ends of 2 are hung and fixed between a pair of adjacent steel hauls 1, 1. The module width W is a normal standard dimension of a building, for example, 100
0 mm, 910 mm, 900 mm, 800 mm, etc.

The floor panel 2 is composed of a plurality of wooden joists 2b arranged in parallel with the floor surface material 2a attached thereto, and is fixed to the steel haul 1 by a fixing screw 3 such as a tapping screw with a drill. It As the floor panel 2 in this case, as shown in FIG. 2 (A), one end of the floor surface material 2a is placed at the middle position in the width direction on the joist 2b at the corresponding end, and the other end of the floor material 2a is placed. Is used, which is protruded from the other end of the joist 2b in the width direction by the arrangement pitch of the joist 2b. The end portion of the floor surface member 2a on the protruding side is placed on the width-direction half portion on the joist 2b of the end portion of the adjacent floor panel 2 shown by a chain line in the figure. By using such a floor panel 2, one floor joist 2b on which the floor coverings 2a, 2a of both floor panels 2 are placed is shared by two floor panels 2 and 2 adjacent to each other. Alternatively, as shown in FIG. 2B, a floor panel 2A may be used in which both ends of the floor panel 2a are placed on the corresponding joists 2b over the entire width direction.

In this example, the steel raft 1 is made of a pipe material having a substantially square cross section, and is supported on a bundle base 5 via a steel bundle 4. As shown in FIG. 3A, the steel bundle 4 is configured by connecting a large pulling tool 6 having an L-shaped cross section and a base plate 7 with a turnbuckle 8, and a nail hole 7 a of the base plate 7.
The concrete nail 9 to be inserted into the bundle base 5 is driven into the bundle base 5 so as to stand upright on the bundle base 5 as shown in FIG. 3 (B).

According to the floor structure for preventing floor squeal of this construction, the wooden joists 2b of the floor panel 2 are dried and shrunk as shown in FIG. 4 (B) to the floor panel in the construction state of FIG. 4 (A). Even if the warp 2 occurs, since each floor panel 2 is a simple beam with respect to the steel rafts 1, there is no gap between the joists 2b and the steel rafts 1 and floor squeal can be prevented. Moreover, since the steel raft 1 is used as the raft 1 on which the floor panel 2 is placed,
There is no deformation such as warping or twisting due to drying shrinkage, good dimensional stability, and improved workability. Further, even if the steel daiiki 1 is used, by using the steel bundle 4,
Construction of Daihiki 1 can be done easily. In addition, as shown in FIG. 6, the arrangement interval of the steel hauls 1 is set to an integral multiple of the module width W (twice in the illustrated example), and the floor panel 2 is made of steel hauls 1, 1 having both ends adjacent to each other. Steel draping 1 so that it can be bridged between
The width B1 may be the same as the arrangement interval. The width B2 of the other side of the floor panel 2 is an integral multiple of the submodule width w. The sub-module width w means a width that is a fraction of the module width W. Therefore, the width B2 of the other piece of the floor panel 2 becomes a width of (n / m) W, for example, 0.5W,
The width is 0.75W, 2 / 3W, 1.5W, etc. In the illustrated example, the width B2 matches the module width W. The construction of the floor panel 2 is the same as the floor panel 2 of FIG. 1 except that the width dimension is different. Even in the case of such a configuration, since each floor panel 2 is a simple beam, there is no gap between the joist 2b and the steel haul 1 and floor squeal can be prevented.

FIG. 7 shows a second embodiment of the present invention. The floor squeal prevention floor structure using the steel haul of this embodiment is shown in FIG.
As shown in FIG. 7 (B), (C), a floor panel 2 in which a floor covering 2a is stretched on a joist 2b as shown in FIG. As shown in a side view, a front view, and a rear view in (D), slits 10 for preventing joist warp bending are provided at locations where the joists 2b of the floor panel 2 are to be placed on the steel raft 1 at an intermediate portion in the longitudinal direction. Has been formed. The slit 10 completely divides the joist 2b in this example. The steel draft 1 is installed with the module width of the building as in the above-mentioned embodiment, and the floor panel 2 has the module width on the short side,
The long side is twice the module width.

In addition, the floor panel 2 in this case is also shown in FIG.
As shown in (B), one end of the flooring material 2a is placed at the middle position in the width direction on the joist 2b, and the other end of the flooring material 2a is arranged on the joist 2b by the pitch of the joists 2b in the width direction. However, a floor panel in which both ends of the floor panel 2a are placed over the corresponding joists 2b over the entire width direction may be used. As in the case of the previous embodiment, the floor panel 2 is fixed to the steel draft 1 by a fixing screw 3 such as a tapping screw with a drill, but the floor panel 2 is intermediate in the longitudinal direction of the joist 2b. In the portion where the slit 10 is formed, as shown in FIG. 7 (E), it is fixed to the steel haul 1 with the fixing screws 3 at two places sandwiching the slit 10. The other structure is the same as that of the previous embodiment.

In the floor noise preventing floor structure of this embodiment, the floor panel 2 is longer than the module width.
Since the joists 2b are made bendable by forming the slits 10 and are placed on the steel rafts 1 at the positions where the slits 10 are formed, the joists 2b are fixed across three or more steel rafts 1. Nevertheless, the floor panel 2 becomes a pseudo simple beam between the adjacent steel rails 1 and 1, and floor squeal is prevented. Further, since the floor panels 2 are long, the number of floor panels 2 can be reduced as compared with the example of FIG. 1, and the number of construction steps can be reduced. Other functions are similar to those of the previous embodiment.

When a strong surface material such as a thick waterproof plywood called a concrete panel is used as the floor surface material 2a of the floor panel 2, a slit for completely dividing the joist 2b as described above. 10 is used, but when a weak surface material such as particle board is used as the floor material 2a, it is configured as follows. That is, as shown in FIG. 7 (F), the slit 10 is formed from the lower end of the joist 2b toward the upper end with a predetermined thickness h ₁ left from the upper end of the joist 2b, or the joist 2b is removed as shown in FIG. 7 (G). After forming the slit 10 so as to be completely divided, a reinforcing plate 11 is attached between the side surfaces of the divided joists 2b ₁ and 2b ₁ .
The fasteners 12 such as nails are used for fixing and coupling. As a result, it is possible to freely bend the slit 10 of the floor panel 2, while avoiding bending and damage of the floor surface material 2a during transportation or construction. When forming the slit 10 that does not divide the joist 2b as shown in FIG. 7 (F), the height h ₁ of the uncut portion is set to the height h of the joist 2b according to the strength of the floor covering 2a, for example. Adjust and set to 1/3 to 1/4.

FIG. 8 shows a third embodiment of the present invention. In the floor squeal preventing floor structure using the steel haul of this embodiment, a floor panel 2 in which a floor surface material 2a is stretched over a plurality of joists 2b is shown in FIG.
(A) is a floor structure placed on a plurality of steel rafts 1 and has a thick smooth sheet 13 having a cushioning property between the joists 2b of the floor panel 2 and the steel rafts 1. Is interposed. The smooth sheet 13 is, for example, high-molecular polyethylene,
It is made of other chemical film or a laminated sheet of a metal sheet such as zinc and a resin sheet.
As shown in FIG. 8B, the surface is a smooth surface 13a having high wear resistance, the intermediate layer is a cushioning material layer 13b, and the back surface is an adhesive layer 13c. As shown in FIG. 8D, the bottom surface of the joist 2b of the floor panel 2 is It is preliminarily adhered and fixed to a portion corresponding to the steel haul 1. This sliding material 1
On the contrary, 3 may be bonded to the upper surface of the steel haul 1. The other structure is similar to that of the first embodiment.

In the floor squeal preventing floor structure of this embodiment, for example, the wooden joist 2b is dried and shrunk so that the joist 2b and the steel haul 1
Even if there is a gap between the large timber 1b and the joist 2b of the floor panel 2, the cushioning action of the smooth sheet 13 interposed between the joist 2b of the floor panel 2 and the steel big haul 1 results in the large haul 1 and the joist 2b when a load is applied. The impact of is absorbed and the collision noise is reduced. In addition, the smooth sheet 13
Due to the reduction of the slip resistance due to the above, even if shear displacement occurs in the joist 2b with respect to the steel hauling 1, the generation of rubbing noise is prevented. In this way, both collision noise and slip noise are prevented from ringing on the floor. In addition, a slight dimensional change between the steel haul 1 and the joist 2b due to the contraction of the joist 2b is absorbed by the elastic deformation of the smooth sheet 13, and a gap is prevented from occurring. This also reduces floor noise. Further, when the floor panel 2 is installed, the smooth sheet 13 reduces the slip resistance, so that it can be slid on the Daihiki 1 and the workability is improved. In addition,
The smooth sheet 13 may not have a cushioning property, and in that case, as shown in FIG. 8C, for example, it is a single material sheet. When the smooth sheet 13 having no buffering property is used, for example, a metal sheet of zinc or the like, a resin sheet, or a resin-coated metal sheet can be used.
Even if it does not have a cushioning property as described above, the floor squeal preventing effect and the like due to the above-described sliding action can be obtained.

FIG. 9 shows a fourth embodiment of the present invention. The floor squeal preventing floor structure using steel haul of this embodiment is the floor structure of the first embodiment to which the smooth sheet 13 used in the third embodiment is applied. That is, as shown in FIG. 9 (A), among the plurality of steel rafts 1 provided in parallel with the module width W of the building, one side is provided between the adjacent steel rafts 1 and 1 with the module width W. In a floor structure in which both ends of a substantially square floor panel 2 having substantially the same size as the above are hung and fixed, a smooth sheet 13 having a cushioning property is interposed between the joist 2b of the floor panel 2 and the steel haul 1. It is a thing. In this case as well, the smooth sheet 13 is adhered to the portion of the bottom surface of the joist 2b of the floor panel 2 that is in contact with the steel pull 1 as shown in FIG. 9B.
On the contrary, it may be adhered to the upper surface of the steel pull 1. The other structure is the same as that of the first embodiment.

In the floor squeal preventing floor structure of this embodiment, the floor panel 2 is a simple beam with respect to the steel draft 1 and the floor sheet 2 with respect to the steel draft 1 is acted by the action of the smooth sheet 13. Since it can slide with a small frictional resistance, the floor noise prevention effect is further improved. Other functions are similar to those of the first embodiment.

FIG. 10 shows a fifth embodiment of the present invention.
The floor structure of this embodiment has a joist 2b as shown in FIG.
It is a floor structure in which a floor panel 2 having the above is placed on a plurality of steel rafts 1, and it penetrates a joist 2b of the floor panel 2 as shown in FIG. The elastic body 14 is sandwiched between the head 3a of the fixing screw 3 such as a tapping screw with a drill and the upper surface of the joist 2b. Each fixing screw 3 is provided in a counterbore hole 25 penetrating the floor surface member 2a, and the elastic body 14 is arranged on the joist 2b. The elastic body 14 is composed of a large number of disc springs stacked in this example, but other than this, hard rubber or polymer material may be used. Other configurations are similar to those of the second embodiment and the like.
It should be noted that the fixing screw 3 is used in the counterbore 2 when it is hidden by the wall.
There is also a case where it is driven from the surface of the floor surface material 2a as shown in FIG. 11 (A) without providing 5, but in that case, the elastic body 14 is provided between the head portion 3a of the fixing screw 3 and the floor surface material 2a. Intervene. When the counterbore hole 25 is a bottomed hole as shown in FIG. 11B, the bottom surface of the counterbore hole 25 and the head 3 of the fixing screw 3 are used.
An elastic body 14 is interposed between the elastic body 14 and a.

In the case of this floor structure, the wooden joist 2b may dry and shrink from the state of construction shown in FIG. 10 (C), and the head 3a of the fixing screw 3 may rise from the upper surface of the wooden joist 2b. Also, following the change, the elastic body 14 is restored as shown in FIG. Therefore, no gap is formed between the joist 2b and the steel haul 1, and floor ringing due to the generation of the gap is prevented.

FIG. 12 shows a sixth embodiment of the present invention.
The floor structure of this embodiment has a mechanism for preventing loosening of the fixing screw 3 by the elastic body 14 used in the embodiment of FIGS. 10 and 11.
It is applied to the floor structure of the embodiment.

In the construction of this embodiment, the floor panel 2 is a simple beam with respect to the steel draft 1 and the joist 2b and the steel draft 1 are provided by the loosening prevention mechanism of the fixing screw 3 by the elastic body 14.

Other configurations are the same as those in the first embodiment. The steel haul 21 may be used in the second to sixth embodiments.

In the case of this floor structure, since the steel pulling 21 has a wide upper surface, the joists 2b of the floor panel 2 can be received by a wide supporting surface, and the floor panel 2 can be stably supported. That is, at the place where the floor panels 2 are lined up, one steel large pull 21 receives two adjacent floor panels 2, but each floor panel 2 can be formed by having an inverted trapezoidal cross section in this way.
It is possible to obtain a large hanging allowance for the steel haul 21 of. The lower side of the steel haul 21 need only be capable of transmitting a load to the steel bundle 4, and therefore does not need to be as large as the upper side, and the material is saved by narrowing the width.
