Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a level-adjustable floor support material for improving building members.

[Prior Art] Conventionally, when building a floor above the slab surface of the body,
As shown in FIG. 7, in order to adjust and support the upper surface of the floor joist 51 with the floor plates 50 arranged side by side at a predetermined horizontal height H,
Between the upper surfaces of the 51 and the slab 52, a wood material 53 made of wood ends is erected, but since the top surface of the slab 52 is not finished horizontally, a wedge 54 made of wood ends is generally used as the wood material 53.
The level adjustment is carried out by inserting it under the feet, and the adjustment work is troublesome because a large number of fillers are used, and there is a problem that a great deal of labor is required.

[Problems to be Solved by the Invention] The present invention has been made in view of the above problems, and an object thereof is to provide a bracing material that can easily adjust the level when a floor is constructed above the slab surface of a body. It is what

[Means for Solving the Problems] A level-adjustable floor-supporting padding material according to the present invention is a padding material that is erected in a gap between a joist and a slab in which floor plates are arranged in parallel according to the construction height of the floor surface. In, a bottomed cylindrical leg member having a female screw screwed on the inner diameter, and a cylindrical male screw member having a male screw screwed on the outer periphery over its entire length to be screwed with the female screw of the leg member, The male screw member and the leg member are composed of respective parts of a cylindrical female screw member in which an internal thread is provided with a female screw of the same pitch as the female screw of the leg member to be screwed with the male screw of the male screw member. Alternatively, the gist is to connect and use all of the parts by a single or plural screwed combination. Further, in the above structure, it is preferable to engrave the anti-skid knurls on the outer surface of the end plate of the leg member and at least one end of the male screw member.

[Operation] Since the three types of parts of the leg member, the male screw member, and the female screw member can be screwed and connected by screws, floors of various heights can be obtained by combining the three types of parts during the floor construction work. Can be adapted to the level.
Further, since the screwing of the screws between the combined parts can be finely adjusted, the horizontal level of the floor surface can be easily adjusted.

[Embodiment] An embodiment of a level-adjustable floor supporting material according to the present invention will be described below with reference to the drawings.

The level-adjustable floor supporting material of the present invention is basically composed of three kinds of parts of a leg member 1, a male screw member 2 and a female screw member 3, each of which is molded of hard synthetic resin or metal. It becomes.

The leg member 1 has a bottomed cylindrical shape with an outer diameter W1 of about 30 mm and a length L1 of about 40 mm. A male screw 4 is screwed on the inner diameter of the leg member 1 and an end plate.
The knurl 5 for slip prevention is engraved on the outer surface of 5a.

The male screw member 2 has a cylindrical shape with an outer diameter W2 of about 20 mm and a length L2 of about 40 mm, and a male screw 6 which is screwed to the female screw 4 of the leg member 1 is screwed on the outer circumference of the cylindrical member. In addition, an anti-slip knurl 7 is engraved at one end.

The female screw member 3 has a cylindrical shape with an outer diameter W3 of about 30 mm and a length L3 of about 40 mm, and the inner screw 6 of the male screw member 2 has an inner diameter.
A female screw 8 having the same pitch as that of the female screw 4 of the leg member 1 to be screwed with is screwed.

The level-adjustable floor-supporting wood 9 having the above structure is used in the same manner as a wood-based wood-supporting wood by connecting three types of parts to each other according to the construction height of the floor surface. That is, the level adjustment is performed instead of the wedge by adjusting the mutual screwing. That is, as shown in FIG. 5, the fillers 9 which are combined according to the gap H between the floor joists 11 and the slab 12 which are installed in parallel are set up at a predetermined interval and fixed to the surface of the slab 12 with an adhesive or the like. A crenellated joist 11 is placed on each sill material 9, and the screwing of the parts is adjusted so that the upper surface of the creped joist 11 is supported horizontally.

FIG. 6 shows the basic connection of the level-adjusting floor support members 9 to the gap H. Depending on the gap H between the slab 12 and the slab 12, the appropriate combination may be made as in the following example. It is used by changing it.

(A) One leg member 1 and one male screw member 2 are screwed and connected, and H can be used in the range of 45 to 70 mm.

(B) Leg members 1 and 1 are screwed and connected to both ends of the male screw member 2, and H can be used in a range of 80 to 100 mm.

(C) The leg member 1, the male screw member 2, the female screw member 3, and the male screw member 2 are screwed and connected in this order, and H can be used in the range of 100 to 130 mm.

(D) The leg member 1, the male screw member 2, the female screw member 3, the male screw member 2 and the leg member 1 are screwed and connected in this order, and H is 12
It can be used in the range of 0 to 160 mm.

[Effects of the Invention] As described above, the level-adjustable floor supporting material according to the present invention can be applied to floor levels of various heights by combining three types of parts during floor construction work. At the same time, the horizontal level can be easily adjusted by the screws of the combined parts, so that the workability is improved, and the practical effect after the present invention is extremely large.
