BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a joist when constructing a floor.

[0002]

2. Description of the Related Art Conventionally, as a frame of a floor assembled on a building floor, there is a structure shown in FIGS.
Those shown in FIG. 3, Obiki 2 P ₁ on the subfloor 1 of the precursor
(Specifically, 909 mm), and the joists 3 are arranged on the pulley _{2 at} a pitch of P2 (specifically, 305 to 455 mm) so as to be orthogonal to the pulley 2. It has a fixed structure. At this time, in order to output the horizontal level of the joist 3, a leveled mortar 4 or the like is disposed under the pulling bar 2 using a level, and the level is adjusted with the dumpling.

FIG. 4 shows a particle board,
A plurality of floor panels 5 made of plywood or the like are arranged side by side on the floor substrate 1 of the skeleton. Then, the level is adjusted, and a discarded plywood 7 is stuck on the floor panel 5.

[0004]

However, in the former case of the prior art, the level adjustment is performed by disposing a mortar 4 or the like in a dumpling shape using a level, so that the work is troublesome. There is a problem that such techniques are required and that the technique is required (if the level is not accurately set, floor noise will occur after floor finishing material is installed). Further, there is a problem in that the above operation cannot be performed until the mortar 4 is hardened, so that the construction period is long.

[0005] In the latter conventional example, the work can be carried out by the dry method and the level can be easily adjusted. However, the structure becomes complicated and the amount of members used is large (since discarded plywood and the like are required), and the cost is low. There is a problem that the use is limited because it leads to up. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to make it possible to easily adjust the level of the joist, to easily perform the construction in a short construction period, and to reduce the cost in terms of cost. In providing structure.

[0006]

In order to achieve the above object, the joist supporting structure of the present invention comprises a pair of supporting bolts 6 on a base plate 8.
Screwed up and down at predetermined intervals so as to freely move up and down, the anti-vibration rubber 9 provided independently at the lower end of each support bolt 6 is installed on the floor base 1, and protrudes above the base plate 8 of each support bolt 6. Control to the top
The working groove 15 was provided, and the joist 3 erected horizontally was placed on the base plate 8 and supported.

[0007]

According to the above construction, the level of the joist 3 can be adjusted by operating the support bolt 6 to move the base plate 8 up and down, and the level of the joist 3 can be easily adjusted. Support bolt 6
The level can be adjusted by adjusting the floor finish material, so that the finishing work can be done immediately and the construction period can be shortened. The vibration isolating performance can be improved by the vibration isolating rubber 9 at the lower end of the support bolt 6. Since it does not require large-scale or discarded plywood, low cost and reduced construction are possible.
A rubber base 9 at the lower end of each of the pair of support bolts 6 is used as a floor base.
Stable even if there is unevenness in the ground floor 1
Can be installed well. The operation groove 15 at the upper end of the support bolt 6
To easily turn the support bolt 6 from above
Can be adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a joist supporting device A is mainly composed of a base plate 8 and a pair of supporting bolts 6. Base plate 8
Is formed in a rectangular parallelepiped shape by plywood, particle board or the like. As the size of the base plate 8, the width W is desirably about 100 to 200 mm and the thickness t is desirably 20 to 30 mm so that the general joist 3 can be received. It is desirable that an adhesive 10 is attached to the surface of the base plate 8. Support bolts 6 are arranged on both sides of the base plate 8, and the support bolts 6 are screwed into the base plate 8 so as to be vertically movable. The distance L between the pair of support bolts 6 is desirably about 60 to 100 mm. An operation groove 15 such as a minus groove for operating the support bolt 6 is provided at an upper end of the support bolt 6. This support bolt 6
Has sufficient strength to support a fixed load and a load on the floor, and is made of a resin such as nylon or a metal. An anti-vibration rubber 9 for improving the anti-vibration performance of the floor is mounted on the base 11 at the lower end of the support bolt 6.

Using the joist supporting device A, a floor is constructed as shown in FIG. First, the joist 12 is mounted around the room. At this time, 303-4 so that joist 12 does not sink
The bundle 13 is erected at a pitch of 55 mm to support the joist 12. Then subfloor of precursor to the marking at a pitch of P ₁ (specifically 909Mm) on the (concrete base and Kinoshita land), further orthogonal directions in the P ₂ pitches (specifically 3
(03 to 455 mm). Then the joists 3 cut into a length dimension necessary located along the marking lines of the pitch P ₁ joist when the ends of the joists 3 room 12
On top of. Then, the joist 3 is securely fixed from above the joist 3 to the edge joist 12 using a screw nail or a screw so as not to fall down. Next, the joist support device A is fitted under the joist 3 along the mark line of the pitch P ₁ , and the joist 3 is placed on the base plate 8. At this time, the joist 3 is temporarily fixed on the base plate 8 with the adhesive material 10. After temporarily fixing joist 3, joist 3
It is fixed to the base plate 8 at two or more places with screw nails or screws from above. After that, the length adjustment is performed by adjusting the length of the support bolt 6. At this time, the level adjustment is performed sequentially from around the room. After level adjustment, finish the floor by applying a floor finishing material such as a wooden floor material.

[0010]

Since the present invention is constructed as described above, the level of the joist can be adjusted by operating the support bolt and moving the base plate up and down, and the joist level can be easily adjusted. Since the level can be adjusted by adjusting the support bolts, it can be easily installed by the dry method, the floor finishing material can be installed immediately, the construction period can be shortened, and anti-vibration rubber is attached to the lower end of the support bolt. Since it is installed, it can improve the vibration isolation performance of the floor, and because it does not require large-scale or discarded plywood as in the past, it is possible to reduce cost and save construction work.
And a pair of support bolts on the base plate at a predetermined interval.
Anti-vibration installed independently at the lower end of each support bolt
Rubber is installed under the floor, so it is stable with a pair of support bolts
Even if it supports well, the lower end of each support bolt is prevented.
The vibration rubber can be installed on the floor base, respectively.
It can be installed stably even if there is unevenness in
Also, screw a pair of support bolts into the base plate, and
Operation groove is provided at the upper end protruding above the plate, so it is supported from above
The height can be easily adjusted by easily rotating the bolt.
