Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joist construction method which is particularly useful in a floor construction method for constructing an apartment or the like, and a joist bracket used therefor.

[0002]

2. Description of the Related Art Conventionally, in the dry floor construction method, FIG.
As shown in FIG. 3, a sash joist 22 (or joist unit) is provided along a predetermined height of the room wall or the partition 23,
One side of the floor panel 26 is supported on it. The other edge of the floor panel 26 that is not in contact with the joist 22 is mounted in a cantilevered state on a vertically adjustable support block 28 arranged on a concrete slab 27 at a pitch of about 450 mm. The support block 28 and the floor panel 26 are attached to each other via an adhesive sheet or the like adhered to the upper surface of the support plate of the support block. Adjacent floor panels 26 are similarly placed on the already installed support blocks 28 with a predetermined level adjustable level of the floor panels, and other support blocks are similarly arranged and attached. Repeat this work for each floor panel, and in areas such as the corners of the room where the standard floor panel does not fit,
After attaching the joint joists 22, the standard length plate is processed, the dimensions are matched, and the support blocks 28 are appropriately arranged, and the floor panel 26 is spread over the whole. After that, if necessary, a throwing plywood (not shown) is spread so as to cover all floor panels to form a floor base.

In the above floor laying method, when installing joists on the wall or partition, as shown in FIG. 12, the joist 22 is attached to the wall or partition 23 at a predetermined floor height while measuring the height. Then, as shown in FIG. 13, a bundle 24 having adhesive applied to the upper and lower end surfaces for supporting the joist 22 is inserted between the concrete slab 27 and the joist 22 at an appropriate interval. After that, as shown in FIG. 14, nails 29 are struck from the upper portion to fix the joist 22 and the bundle 24. However, in the case of this method, the work of attaching the thick joists is extremely complicated. Moreover, the height adjustment of the thick joists is performed while adjusting the height of the thick joists when they are nailed to the wall or the partition, and the height of the bundle must be cut in accordance with each case. Since the final height and strength of the joists are determined by the length of the bundle cut according to the height, it is complicated to adjust the height, and inevitably there is rattling, and the height once fixed is later fixed. It is impossible to fine-tune.

On the other hand, as another method, as shown in FIG. 15, there is a method of using a joist unit 30 in which a supporting leg 32 is attached to a joist 31 so as to be vertically adjustable. When such a joist unit 30 is used, there are advantages that the mounting work is simple and the height can be adjusted. However, in this method, the joist unit 30 is used by simply leaning against the wall or the partition 23, but since the surface of the wall or the partition is not smooth, there is a gap between the joist unit 30 and the wall or the partition 23. For this reason,
Whenever a person walks on the floor and receives a load, the joist unit 30
There is a problem that a squeaking noise is generated due to the rubbing between the wall and the partition 23.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems, to easily perform the mounting work, and to easily adjust the height of the floor level so that the joists can be used as a wall. Another object of the present invention is to provide a joist construction method capable of adjusting the height even after being fixed to the partition and a joist receiving metal fitting used for the method. Another object of the present invention is to prevent a squeaking noise when a person walks on the floor and receives a load,
It is also possible to cut off the transmission of floor impact sound through a wall, and to provide a joist construction method and a joist receiving metal fitting used for the method, which substantially eliminates the problem of sound in an apartment house or the like.

[0006]

[Means for Solving the Problems] The joist construction method of the present invention is
In order to achieve the above object, a step of arranging and fixing a joist material along a wall or a partition, an L-shaped receiving member having a screw hole on an outer side surface, and a screw portion screwed into the screw hole at least at an upper end portion. A step of arranging a joist receiving metal fitting composed of a supporting leg portion provided with the L-shaped receiving member to support the joist material, and fixing the L-shaped receiving member of the joist receiving metal fitting to the joist material; And a step of rotating the support leg to adjust the height. In this construction method, according to a preferred mode for further reducing the squeaking sound,
A cushioning material is placed between the joists and the wall or partition.
Further, according to the present invention, it is characterized by comprising an L-shaped receiving member having a screw hole on an outer side surface thereof, and a supporting leg portion having at least an upper end portion provided with a screw portion screwed into the screw hole. A joist bracket is provided. According to one preferred aspect, as the L-shaped receiving member, an L-shaped receiving member in which a screw receiving portion having a screw hole is provided on the outer surface of one side of the L-shaped metal fitting is used. As the portion, a support leg portion is used, which includes a support bolt having an outer peripheral surface threaded and an upper end surface provided with a height adjusting groove, and a pedestal fixed to the lower end portion of the support bolt.

[0007]

According to the present invention, the L-shaped receiving member having the screw hole in the outer surface portion and the supporting leg portion having the screw portion screwed into the screw hole at least at the upper end portion are provided. Since the joist material is supported using the joist receiving metal fitting, it is possible to easily perform joist construction. For example, an L-shaped receiving member of the joist receiving bracket in which the length of the supporting leg is set to a predetermined floor height is arranged along a wall or partition while supporting the joist, and in that state the joist is placed on the wall or After fixing to the partition by a suitable means such as nails or screws or an adhesive sheet, after fixing the L-shaped receiving member to the joist by suitable means such as nails or screws or an adhesive,
The floor height can be finely adjusted by rotating the support legs. In addition, after fixing the joists to the wall or partition by adjusting the height while adjusting the height, fix the L-shaped receiving member to the joists by the appropriate means, and rotate the supporting legs to contact the concrete slab. By doing so, you can easily reinforce the joists. Therefore, joist construction can be performed easily, and since the joist is fixed to the wall or the partition, the squeaking noise of the floor due to the load applied when a person walks is also reduced. Further, since the L-shaped receiving member of the joist bracket can be adjusted up and down, the height of the joist can be finely adjusted even after the joist material is fixed to the wall or partition with nails or the like. Furthermore, by interposing a cushioning material between the joists and the wall or partition, the squeaking noise of the floor can be further reduced. It is also possible to block the propagation of floor impact sound and vibration from the wall.
