DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure for preventing noise from a floor in a house or other building using a steel pulley.

[0002]

2. Description of the Related Art Conventionally, the structure shown in FIG. 15 has been adopted as a floor structure in which a floor panel is mounted on a large scale. Floor panel 30
Consists of a flooring material 30a and a joist 30b, and is hung between a plurality of parallel wooden gibs 31, and is fixed to the giant 31 by fixing members 32 such as nails or screws.

[0003]

However, in the above-described floor structure, the floor panel 30 is stretched over the three large bridges 31, and the floor panel 30 is a continuous beam with respect to the large bridge 31. When the joists 30b of the floor panel 30 warp upward, FIG.
As shown in Fig. 6 (A), the joist 30b and the oiki 31 at the center of the panel
A gap is formed between the floor panel 3 and the floor panel 3 as shown in FIG.
Floor noise occurs when the load G is applied to zero. For example,
A collision sound is generated between the joist 30b and the gibbon 31. The joists 30b of the floor panel 30 are in direct contact with the large pulleys 31 and are fixed by the fasteners 32. However, the joists 30b and the large pulleys 31 are fixed by dry shrinkage, screws or the like due to repeated load. When the holding force of the tool 32 is reduced, when the load G is applied, shear displacement occurs on the joint surface, and a rubbing sound is generated.

Further, when the wooden joists 30b of the floor panel 30 dry shrink, the screws 32 which cannot follow the movement loosen from the state of FIG. 17A as shown in FIG. Therefore, a floor noise is generated due to such a cause. Also, 31
When is made of wood, there is a problem that deformation such as warping and twisting during drying shrinkage is large, dimensional stability is lacking, and workability is adversely affected.

SUMMARY OF THE INVENTION An object of the present invention is to provide a floor squeal prevention floor structure made of steel and which has good dimensional stability and workability.

[0006]

According to a first aspect of the present invention, there is provided a floor noise preventing floor structure, comprising a plurality of steel pulleys provided in parallel with a module width of a building, and a substantially square having one side of the module width. And a floor panel spanned between the steel girders whose both ends are adjacent to each other. The floor noise prevention floor structure according to the second aspect of the invention has a plurality of steel pulleys provided in parallel at intervals of an integral multiple of the module width of the building, and one side of the floor pulley has substantially the same interval as the steel pulley. A rectangular floor panel formed to have a width and the other side having a width that is an integral multiple of the width of the sub-module of the building, and having both ends bridged between the adjacent steel girders. In this specification, the sub-module width means a width that is a fraction of the module width. Therefore, the other piece of the floor panel, if the module width is W,
(N / m) W. m and n both represent natural numbers.

A floor structure for preventing floor noises according to a third aspect of the present invention is a floor structure in which a floor panel having a floor surface material stretched on a joist is placed over at least three steel girders. A slit for preventing joist warping and bending is provided at a position on the steel pulley at the middle portion in the longitudinal direction of the steel plate.

According to a fourth aspect of the present invention, there is provided a floor sound-preventing floor structure in which a floor panel having a joist is placed on a plurality of parallel steel pulleys. A smooth sheet is interposed between the puller and the puller, and the flat sheet is attached to either the joist or the steel puller.
The smooth sheet may have a buffering property or may not have a buffering property.

According to a fifth aspect of the present invention, there is provided a floor noise preventing floor structure, wherein a floor panel having a wooden joist and a floor surface material provided on the joist is placed on a plurality of parallel steel pulleys. A fixing screw which penetrates the joist and is screwed into a steel pulley is provided, and an elastic body is sandwiched between the head of the fixing screw and the upper surface of the joist or the floor material. The upper surface of the flooring material may be the bottom surface of the concave portion counterboiling on the flooring material.

[0010] In the floor structure for preventing floor noises according to the above inventions,
The steel pulley is an inverted trapezoidal cross-section steel plate bent pipe material in which the upper surface width is wider than the lower width, and the upper plate portion and both side plate portions of the steel pulley are also formed as a trapezoidal wave corrugated cross section. Good.

Further, in the floor noise preventing floor structure according to each of the inventions, the steel pulley may be installed on a steel bundle.

[0012]

In the structure of the first and second aspects of the present invention, the floor panel is a simple beam with respect to the steel pulley. There is no gap between floor panels, and floor noise is prevented. Also,
Since Daihiki is made of steel, there is no drying shrinkage, dimensional stability is improved, and workability is improved.

According to the construction of the third aspect of the present invention, the joist of the floor panel can be freely bent at the slit forming portion at the middle portion in the longitudinal direction, and is placed on the steel pulley at the bendable portion. The floor panel is simulated as a simple beam. Therefore, even if drying shrinkage occurs on the floor panel, no gap is formed between the floor panel and the floor panel, and floor noise can be prevented.

According to the construction of the fourth aspect of the present invention, since the smooth sheet is interposed between the joist of the floor panel and the steel pulley, even if the joist deviates from the pulley, the smooth sheet rubs. Floor noise caused by sound is prevented. In addition, when the floor panel is constructed, the large sheet can be slid up and down due to the sliding of the smooth sheet, thereby improving the workability. When the smooth sheet has a cushioning property, even if a gap occurs between the joist and the pulley and a collision occurs, floor noise due to the collision sound can be prevented by the buffer effect of the smooth sheet.

In the structure of the fifth aspect of the present invention, the elastic body is interposed between the head of the fixing screw that penetrates the wooden joist of the floor panel and is screwed into the steel pulley and the upper surface of the joist or the floor surface material. Therefore, even if the joist dries and shrinks, the elastic body is restored following the change and the loosening of the fixing screw is prevented. Therefore, there is no gap between the joist and the pulling, and floor noise is prevented.

When the steel puller is made of a bent steel plate having an inverted trapezoidal cross section, the surface for receiving the floor panel is widened and the floor panel can be supported stably. Since the lower part of the steel pulley only needs to be able to transmit a load to a steel bundle or the like, it is not necessary to be as wide as the upper part. In addition, since the steel plate has a wavy cross section of a trapezoidal wave at the upper plate portion and both side plate portions, the steel plate is prevented from slackening, and the cross-sectional strength against bending and twisting is improved.

When the steel puller is installed on a steel bundle, the steel pulley can be supported with sufficient support strength by a simple structure.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. This floor squealring floor structure using steel pulleys has a substantially square floor panel in which a plurality of steel pulleys 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. 2 are fixed by bridging both ends between a pair of adjacent steel pulleys 1,1. The module width W is a normal reference dimension of a building, for example, 100
0 mm, 910 mm, 900 mm, 800 mm, and the like.

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

The steel pulley 1 is made of a pipe material having a substantially square cross section in this example, 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 undertaking 6 having an L-shaped cross section and a base plate 7 with a turnbuckle 8, and a nail hole 7a of the base plate 7.
By driving a concrete nail 9 to be inserted into the bundle base 5, the concrete nail 9 is erected on the bundle base 5 as shown in FIG.

According to the floor noise prevention floor structure of this construction, the wooden joists 2b of the floor panel 2 dry and shrink as shown in FIG. Even if warpage occurs in each of the floors 2, since each floor panel 2 is a simple beam with respect to the steel pulley 1, no gap is formed between the joist 2b and the steel pulley 1, and floor noise can be prevented. Further, since the steel pulley 1 is used as the pulley 1 on which the floor panel 2 is placed,
There is no deformation such as warpage or twist due to drying shrinkage, dimensional stability is good, and workability is improved. In addition, even if the steel puller 1 is used, by using the steel bundle 4 described above,
The construction of Daiki 1 can be performed easily. As shown in FIG. 6, the interval between the steel pulleys 1 is set to an integral multiple of the module width W (twice in the illustrated example), and the floor panel 2 is connected to the steel pulleys 1, 1 adjacent at both ends. Steel bridge 1
May have the same width B1 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 is a width of (n / m) W, for example, 0.5W,
The width is 0.75 W, 2/3 W, 1.5 W, or the like. In the illustrated example, the width B2 matches the module width W. The configuration of the floor panel 2 is the same as the floor panel 2 of FIG. 1 except that the width dimension is different. Also in this configuration, since each floor panel 2 is a simple beam, there is no gap between the joist 2b and the steel pulley 1, and floor noise can be prevented.

FIG. 7 shows a second embodiment of the present invention. FIG. 7 shows the floor squeal prevention floor structure of this embodiment using steel pulling.
As shown in FIG. 7B, a floor panel 2 in which a floor panel 2a is stretched on a joist 2b as shown in FIG. As shown in the side view, the front view, and the back view of (D), a slit 10 for preventing joist warpage is provided at a position where the joist 2b of the floor panel 2 is placed on the steel pulley 1 in the longitudinal direction middle portion. It is formed. The slit 10 completely divides the joist 2b in this example. The steel pulley 1 is installed with the module width of the building in the same manner as in the above embodiment, and the floor panel 2 has a short side with the module width,
The long side is twice as wide as the module width.

FIG. 7 also shows the floor panel 2 in this case.
As shown in (B), one end of the floor panel 2a is placed at the middle position in the width direction on the joist 2b, and the other end of the floor panel 2a is shifted from the joist 2b by the pitch of the joists 2b in the width direction. Although only the protruding portion is used, a floor panel in which both ends of the floor panel 2a are placed over the entire width of the corresponding joist 2b may be used. The floor panel 2 is fixed to the steel pulley 1 by a fixing screw 3 such as a tapping screw with a drill, as in the case of the previous embodiment. In the part where the slit 10 is formed, the part is fixed to the steel pulley 1 with the fixing screw 3 at two places sandwiching the slit 10 as shown in FIG. Other configurations are the same as in the previous embodiment.

In the floor noise prevention floor structure of this embodiment, the floor panel 2 is longer than the module width.
The joist 2b is made to be flexible by forming the slit 10 and is mounted on the steel pulley 1 at the location where the slit 10 is formed, so that it is fixed across three or more steel pulleys 1. Nevertheless, the floor panel 2 is simulated as a simple beam between the adjacent steel pulleys 1 and 1 and floor noise is prevented. Further, since the floor panel 2 is 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 operations are the same as in the previous embodiment.

When a strong surface material such as a thick water-resistant plywood called a concrete panel is used as the floor surface material 2a of the floor panel 2, the slit for completely dividing the joist 2b as described above. When the floor material such as a particle board or the like is used as the floor surface material 2a, it is configured as follows. I.e., to form the slit 10 toward the upper end from the lower end of the joists 2b leaving a predetermined thickness of h ₁ than the top of the joists 2b as shown in FIG. 7 (F), or the joists 2b as shown in FIG. 7 (G) After the slit 10 is formed 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 ,
It is fixed and connected with a fixing tool 12 such as a nail. Thus, the floor panel 2a can be prevented from being bent and damaged during transportation, construction, and the like, while allowing the slit 10 of the floor panel 2 to freely bend. As shown in FIG. 7F, in the case of forming the slit 10 that does not split the joist 2b, the height h ₁ of the undivided portion is set to, for example, the height h of the joist 2b according to the strength of the floor material 2a. Adjust and set to 1/3 to 1/4.

FIG. 8 shows a third embodiment of the present invention. The floor noise prevention floor structure of this embodiment using steel pulling is shown in FIG. 8 in which a floor panel 2 in which a plurality of joists 2b and a floor surface material 2a are stretched is used.
(A) A floor structure placed on a plurality of steel pulleys 1 as shown in (A), and a thick smooth sheet 13 having a cushioning property between the joists 2b of the floor panel 2 and the steel pulleys 1 Is interposed. The smooth sheet 13 is, for example, a high-molecular polyethylene,
FIG. 8 is a diagram showing another chemical film or a laminated sheet of a metal sheet such as zinc and a resin sheet.
As shown in FIG. 8B, the surface has a smooth surface 13a having high wear resistance, the intermediate layer has a cushioning material layer 13b, and the back surface has an adhesive layer 13c. As shown in FIG. It is bonded and fixed in advance to a portion corresponding to the steel pulley 1. This sliding material 1
3 may be bonded to the upper surface of the steel pulley 1 on the contrary. Other configurations are the same as those of the first embodiment.

In the floor noise preventing floor structure of this embodiment, for example, the wooden joist 2b is dried and shrunk by the wooden joist 2b and the steel joist 1
Even when a gap is generated between the joist 2b of the floor panel 2 and the steel pulley 1, the damper of the smooth sheet 13 interposed between the joist 2b and the joist 2b when a load is applied. Is absorbed, and the collision noise is reduced. Also, the smooth sheet 13
Therefore, even if a shear shift occurs in the joist 2b with respect to the steel pulley 1, generation of rubbing noise is prevented. In this way, both the floor noises of the collision sound and the slipping sound are prevented. Further, a slight dimensional change between the steel pulley 1 and the joist 2b due to shrinkage of the joist 2b or the like is absorbed by the elastic deformation of the smooth sheet 13, and the generation of a gap is prevented. This also reduces floor noise. Further, when the floor panel 2 is constructed, the sliding sheet 13 can be slid over the pulling pulley 1 to reduce the sliding resistance, thereby improving workability. In addition,
The smooth sheet 13 may not have a cushioning property. In this case, for example, as shown in FIG. 8C, a single material sheet is used. In the case of forming the smooth sheet 13 having no cushioning property, for example, a metal sheet of zinc or the like, a resin sheet, a resin-coated metal sheet, or the like can be used.
Thus, even if it does not have a cushioning property, an effect of preventing floor noises and the like due to the above-mentioned sliding action can be obtained.

FIG. 9 shows a fourth embodiment of the present invention. The floor squealring floor structure of this embodiment using a steel pulling is obtained by applying the smooth sheet 13 used in the third embodiment to the floor structure of the first embodiment. That is, as shown in FIG. 9 (A), one side of the plurality of steel pulleys 1 provided in parallel with the module width W of the building has a module width W between adjacent steel pulleys 1 and 1. In a floor structure in which both ends of a substantially square floor panel 2 having substantially the same dimensions as above are stretched and fixed, a smooth sheet 13 having a buffer property is interposed between the joist 2b of the floor panel 2 and the steel pulley 1. It is a thing. Also in this case, the smooth sheet 13 is adhered to a portion of the lower surface of the joist 2b of the floor panel 2 corresponding to the steel pulley 1 as shown in FIG.
Conversely, it may be adhered to the upper surface of the steel pulley 1. Other configurations are the same as those of the first embodiment.

In the floor sound-preventing floor structure of this embodiment, the floor panel 2 is a simple beam with respect to the steel pulley 1, and the floor panel 2 is moved with respect to the steel pulley 1 by the action of the smooth sheet 13. Since the sliding can be performed with a small frictional resistance, the floor noise preventing effect is further improved. Other operations are the same as 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.
Is a floor structure in which a floor panel 2 having a floor is placed on a plurality of steel pulleys 1 and is screwed into the steel pulley 1 through a joist 2b of the floor panel 2 as shown in FIG. The elastic body 14 is interposed 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 25 penetrated through the floor material 2a, and the elastic body 14 is disposed on the joist 2b. In this example, the elastic body 14 is composed of a multiplicity of disc springs. Alternatively, a hard rubber or a polymer material may be used. Other configurations are the same as those of the second embodiment.
In addition, the fixing screw 3 is provided at the place hidden behind the wall or the like.
As shown in FIG. 11 (A), there is a case where the elastic body 14 is inserted between the head 3a of the fixing screw 3 and the floor surface material 2a without providing the base member 5 as shown in FIG. Intervene. When the counterbore 25 is a hole with a bottom as shown in FIG. 11 (B), the bottom of the counterbore 25 and the head 3 of the fixing screw 3 are formed.
and an elastic body 14 is interposed between the elastic body 14 and a.

In the case of this floor structure, the wooden joist 2b dries and shrinks from the state at the time 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 pulley 1, and floor noise caused by the gap is prevented.

FIG. 12 shows a sixth embodiment of the present invention.
The floor structure of this embodiment has a first mechanism for preventing the fixing screw 3 from being loosened by the elastic body 14 used in the embodiment of FIGS.
This is applied to the floor structure of the embodiment of the present invention.

In the configuration of this embodiment, the floor panel 2 is a simple beam with respect to the steel pulley 1 and the joist 2b and the steel pulley 1 are provided by a mechanism for preventing the fixing screw 3 from being loosened by the elastic body 14.
Can be prevented from occurring, and the effect of preventing floor noise caused by the gap can be further enhanced.

FIG. 13 shows a seventh embodiment of the present invention.

The steel pulley 21 has an inverted trapezoidal cross section in which the upper surface width is wider than the lower surface width, and the upper surface plate portion and both side surface plate portions have a corrugated cross section in which each crest portion has a trapezoidal waveform rib 21a. It is manufactured by bending work such as roll forming of steel sheets.
Both ends in the width direction of the steel plate constituting the steel pulley 21 are joined by a swaged portion 21b in the center of the lower side. Other configurations are the same as those of the first embodiment. The steel pulley 21 may be used in the second to sixth embodiments.

In the case of this floor structure, since the upper surface width of the steel pulley 21 is wide, the joist 2b of the floor panel 2 can be received by the wide support surface, and the floor panel 2 can be stably supported. That is, in the place where the floor panels 2 are arranged, two steel floor panels 2 receive the adjacent two floor panels 2. By adopting such an inverted trapezoidal cross section, each floor panel 2 is formed.
Of the steel pulley 21 can be greatly increased. Since the lower side of the steel pulley 21 only needs to be able to transmit the load to the steel bundle 4, it is not necessary to make the upper side larger, but by reducing the width, the material can be saved. In addition, steel puller 21
Since the upper surface plate portion and both side surface plate portions have a corrugated cross section in which the ribs 21a are formed, looseness is prevented, and the strength of the cross section is improved, and the cross section is more resistant to bending and twisting. In addition, the steel pulley 21 is not welded at both ends in the width direction of the steel plate but is connected by a swaged portion 21b. Therefore, when a zinc-coated steel plate or the like is used, the zinc layer does not melt, and thus the steel plate is prevented from melting. It is not necessary to perform rust treatment or the like.
