The anti-fall 5 is for preventing the floor joist 2 from falling down, reinforcing the space between the floor joists 2 and receiving the floor base material 3, and is a flat plate having the same rectangular outer shape as the floor joist 2. Is formed. Each anti-stop 5 is fixed in a state where the space between the floor joists 2 is completely buried in a direction orthogonal to the longitudinal direction of the floor joists 2.
[0016]
The reinforcing members 30 are fixed to all the places between the floor joists 2 through which the hanging wood receiving members 4 pass, and are arranged on the same row as the anti-fall 5.
The reinforcing member 30 reinforces the space between the floor joists 2 in the same manner as the anti-fall 5 and receives the floor base material 3, and the function of allowing the floor joists 2 to pass over the hoop receiving material 4 so as to straddle it. , And is integrally formed of a floor receiving member 31 and a pair of fixed oblique members 32, 32.
[0017]
From the viewpoint of receiving the floor base material 3 in a state where the upper end portions of the inner side surfaces of the floor joists 2 are connected to each other, the floor receiving material 31 is, for example, made of wood and has a lateral length of 4 inches. It is formed in a flat plate shape having one side surface of a rectangle with a length in the vertical direction having a predetermined strength (for example, 2 inches).
[0018]
The fixed diagonal member 32 connects one half of the lower surface of the floor receiving member 31 to all the portions of the inner side surface of the floor joist 2 except the upper end portion, and raises the passing area of the suspension receiving member 4 as high as possible. From the viewpoint of arrangement on the side (floor base material 3 side), for example, using wood, a value (8 inches) obtained by subtracting the vertical length on the side surface of the floor receiving material 31 from the vertical length on the cross section of the floor joist 2 is defined as one side ( It is formed in a flat plate shape having one side surface of a right triangle in which the length (vertical side) is the length, and a half value (2 inches) of the horizontal length on the side surface of the floor receiving member 31 is the length of the other side (horizontal side).

Such a pair of fixed oblique members 32, 32 are symmetrically arranged on the lower surface of the floor receiving member 31 and are fixed to the floor receiving member 31 using nails, wooden screws, or the like.
The reinforcing member 30 is fixed between the floor base material 3 and the floor joist 2 so as to receive the floor base material 3 and reinforce the space between the floor joists 2 and, at the same time, pass the suspension tree receiving material 4. Is formed in a triangular shape.
[0020]
On the back surface of the ceiling base material 21, a plurality of ceiling edges 22 are fixed in a state of being arranged in parallel or perpendicular to each other at an interval substantially equal to the interval of the floor joist 2. Each ceiling edge 22 is arranged at a position parallel or orthogonal to the longitudinal direction of the floor joist 2 and alternately or orthogonally to the floor joist 2. Between the ceiling edges 22, a cotton block-shaped sound insulation / heat insulation material 23 having sound insulation or heat insulation, such as rock wool or glass wool, is laid, respectively.
[0021]
Hereinafter, the ceiling construction method according to the present invention will be described.
In the factory, the flooring material 3, the floor joist 2, the anti-fall 5 and the reinforcing material 30 are unitized to produce a second floor structure 10, and a ceiling base material 21, a ceiling edge 22, and sound insulation are provided. The first-floor ceiling structure 20 in which the heat insulating material 23 is unitized is manufactured.
[0022]
Then, the second floor and the first floor ceiling are finished by applying a painted wall or a finishing material with beams to the floor base material 3 and the ceiling base material 21, and thereafter, the second floor structure 10 and the first floor ceiling structure 20 To the construction site when necessary.
[0023]
On the other hand, at the construction site, after laying a foundation on a cloth foundation using concrete, the outer floor structure of the house is constructed by performing flooring on the first floor or erecting a plurality of columns.
Then, on the floor, the second-floor floor structure 10 is attached to the outer frame structure, and a predetermined number of the suspension members 4 are attached. In this case, the suspension wood receiving member 4 is passed through a place where the reinforcing material 30 is present between the floor joists 2 according to the construction plan, and is arranged so as to be parallel to the floor joists 2. In this case, the suspension wood receiving member 4 is installed as high as possible in the passage area of the reinforcing material 30.
In the downstairs, the first-floor ceiling structure 20 is hung from the hoop receiving member 4 by interposing a plurality of hangers 24 between the hoop receiving member 4 and the ceiling ridge 22.
[0024]
Hereinafter, the operation of the ceiling structure thus constructed will be described.
When a load is applied to the second floor, between the floor joists 2 without the hoop receiving members 4, the anti-fall 5 reinforces the space between the floor joists 2 while receiving the floor base material 3, while the hoop receiving members 4 Between the floor joists 4, the reinforcing material 30 reinforces the space between the floor joists 2 while receiving the floor base material 3, so that the second floor is hardly bent in the direction in which the interval between the floor joists 2 increases.
When an impact is applied to the second floor, the noise generated by the vibration of the second floor itself is absorbed by the sound insulation and heat insulating material 23, and the vibration of the second floor does not propagate to the first floor ceiling. Noise due to vibration hardly occurs.
[0025]
As described above, according to the present embodiment, in applying the structure in which the suspension lumber 4 is interposed between the floor joists 2, the floor joists 2 without the suspension lumber 4 are reinforced by the anti-fall 5. In addition to the above, since the space between the floor joists 2 where the suspended wood receiving members 4 are located is reinforced by the reinforcing material 30 and the suspended wood receiving members 4 are allowed to pass through, the space between the floor joists 2 is integrated into 2 While maintaining the strength of the floor structure 10, it is possible to sufficiently reduce the distance between the second floor and the first floor ceiling and take measures against noise on the floor.
[0026]
In addition, according to the present embodiment, the outer shape of the reinforcing member 30 is set to a size that fits exactly between the floor joists 2 as in the case of the anti-fall 5, so that the mounting position and mounting of the suspension lumber receiving member 4 are performed. Even if the number is changed, it is sufficient to replace the reinforcing member 30 and the anti-skid 5, so that it is possible to flexibly cope with a change in the construction plan.
[0027]
Furthermore, according to the present embodiment, since the second floor structure 10 and the first floor ceiling structure 20 are each made into a unit and can be manufactured at a factory, the number of operations to be performed at the construction site is reduced. Can be shortened.
[0028]
Another preferred embodiment (second embodiment) of the ceiling structure according to the present invention will be described.
As shown in FIG. 3, in the case of the second embodiment, only the configuration of the reinforcing member 35 is different from that of the first embodiment.
That is, the reinforcing member 35 of the present embodiment forms a pair with the left reinforcing member 35A and the right reinforcing member 35B. The left reinforcing member 35A has a fixing portion 36 for fixing the floor joist 2 on one side and a floor receiving portion 37 for receiving the floor base material 3 on the other side in a shape obtained by bending a rectangular metal plate at a right angle. Are formed, and a connecting portion 38 for connecting the fixing portion 36 and the floor receiving portion 37 are integrally formed by, for example, welding.
[0029]
The length of the fixing portion 36 is set to be substantially the same as the vertical length in the cross section of the floor joist 2. The fixing portion 36 has a plurality of nail holes 36 a for nailing the floor joist 2.
The length of the floor receiving portion 37 is set to be slightly longer than half the interval between the floor joists 2. A plurality of elongated adjustment holes 37 a are formed at the tip of the floor receiving portion 37. The connecting portion 38 has two sides sufficient to connect both the fixing portion 36 and the floor receiving portion 37 to each other, and has a right-angled triangular plate having a hypotenuse inclined at an angle necessary for passing the suspension member 4. It is formed in a shape.
[0030]
The right reinforcing member 35B has a substantially left-right symmetrical shape with the left reinforcing member 35A. Corresponding portions have the same names and symbols, but the length of the floor receiving portion 37 is set to about half the interval between the floor joists 2. The left reinforcing member 35A differs from the left reinforcing member 35A in that a plurality of screws 37b are fixed to the lower surface of the distal end portion of the floor receiving portion 37.
[0031]
As shown in FIG. 4, when such a reinforcing material 35 is fixed between the floor joists 2, first, the right reinforcing member 35B is fixed to one floor joist 2 by nailing, and then the left reinforcing member 35B is fixed. 35A is fixed to the other floor joist 2 by nailing while the screw 37b of the right reinforcing member 35B is fitted in the adjustment hole 37a. Thereafter, the nut 39 is tightened to the screw 37b of the right reinforcing member 35B, thereby integrally fixing the left reinforcing member 35A and the right reinforcing member 35B.
[0032]
As described above, according to the present embodiment, since the reinforcing member 35 can be adjusted with respect to the left reinforcing member 35A and the right reinforcing member 35B while approaching or separating from each other, the spacing between the floor joists 2 can be adjusted. Can be constructed using the same reinforcing material 35, thereby shortening the construction period, flexibly responding to a change in the construction plan, and the like.
[0033]
Further, in the case of the present embodiment, since the floor receiving portion 37 to be joined to the floor base material 3 is thinner than the floor receiving member 31 of the first embodiment, it is possible to make the suspended tree receiving material 4 closer to the floor base material 3. As a result, it is advantageous in reducing the distance between the second floor and the first floor ceiling. The other configuration and operation and effect are the same as those of the first embodiment, and thus the description thereof is omitted.
[0034]
The present invention is not limited to the first and second embodiments, and various changes can be made.
For example, as shown in FIG. 5, when a steel material 51 having an H-shaped cross section is used in place of the floor joist in the ceiling structure, the fixing portion 36 of the reinforcing material 35 shown in the second embodiment is replaced with the steel material 51. What is necessary is just to make it the structure which can be screwed.
[0035]
Further, the reinforcing members 30 and 35 may be shaped so as to reinforce the space between the floor joists 2 and straddle the suspension receiving member 4. For example, the lower edges of the reinforcing members 30 and 35 are formed in an arch shape. You can also.
[0036]
Furthermore, in the case of using the reinforcing member 35 of the second embodiment, if a member capable of holding the fixing portion 36 is attached to the floor joist 2 in advance, the left reinforcing member 35A and the right reinforcing member 35B are temporarily screwed. Since it can be mounted between the floor joists 2, such work can be performed efficiently.
[0037]
Furthermore, as for the mechanism for adjusting the interval between the left reinforcing body 35A and the right reinforcing body 35B, for example, a screw mechanism that moves in the width direction is applied, or the mechanism between the left reinforcing body 35A and the right reinforcing body 35B is used. These can be integrally movable in the width direction by using a link mechanism.
[0038]
In addition, the ceiling structure of the present invention can be applied not only to the second floor and the first floor ceiling, but also to the third floor and the second floor ceiling.
