Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor board supporting device for supporting a finished floor board stretched as a double floor on a structural floor of a concrete building or the like.

[0002]

[Prior Art]

 Conventionally, in the case of forming a double floor on a structural floor such as a concrete structure, joists or large lumbers have been laid on the structural floor, and a finishing floorboard has been placed on it. Such a double floor formation method requires complicated work and requires skilled workers because it is difficult to secure the horizontalness of the finished floor boards.

[0003] In order to eliminate such drawbacks, so that even a non-skilled worker can carry out double-floor construction, the joists and large lumbers laid on the structural floor are eliminated, and the finished floor board is directly supported by the pedestal. There is proposed a floor plate supporting device, for example, a floor plate supporting device as described in Japanese Utility Model Publication No. 60-6107. This conventional floor board supporting device will be described with reference to FIG.

FIG. 10 is a sectional view of a conventional floor board supporting device. The conventional floor board supporting device A includes an adjusting male screw cylinder 101 having upper and lower male screws opposite to each other and a female screw hole 102a screwed into an upper male screw 101a of the adjusting male screw cylinder 101. It has a floor plate receiving plate 102 to be installed, and a circular base 103 in which a female screw hole 103a to be screwed with the lower male screw 101b of the adjusting male screw cylinder 101 is provided.

A hexagonal engagement hole 101c into which a square bar wrench is inserted is formed in the upper part of the inner surface of the adjusting male screw cylinder 101, and a pin insertion hole 101d into which an L-shaped rotation stop pin 104 is inserted is formed at the upper end of the cylinder. Had been drilled. Further, the floor plate receiving plate 102 is provided with several screw holes 102 b, and the finishing floor plate 105 mounted thereon is fixed by screws 106. Further, a nail hole 103b was formed at the center of the circular base 103, and it was fixed on the structural floor 107 using concrete nails 108.

The floor board supporting device A having the above-mentioned configuration is arranged at a predetermined position on the entire floor regardless of the central portion of the floor, near the wall, or at the corner portion, and supports each finishing floor board 105.

[0007]

[Problems to be solved by the device]

 However, the load applied to the floor plate support device A is different at the center of the floor, near the walls, and at the corners, and especially at the corners, the load is 1/4 of the center part. Therefore, use the floor plate support device A of the same structure. Was not economical.

An object of the present invention is to solve the above-mentioned drawbacks of the conventional floor plate supporting device and to provide a simple floor plate supporting device having a structure suitable for a corner portion of a floor.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a floor board supporting device of the present invention comprises a bolt, a bolt end protection member that is fitted to one end of the bolt, and a cylindrical body that is internally threaded with a female screw. And a floor plate support plate protruding from the outer periphery of the side surface of the cylindrical body.

[0010]

[Action]

 In the floor board supporting apparatus of the present invention, first, the bolt end protection member is arranged at a predetermined position on the structural floor. Next, a cylindrical body for projecting the floor plate receiving plate is screwed into a bolt, and one end of this bolt is fitted into a bolt end protection member to stand the bolt on the structural floor. At this time, the support height of the floor plate support plate on the structural floor is accurately adjusted. Then, the floor board is placed on the floor board support plate.

[0011]

【Example】

 Next, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a cross-sectional view of a floorboard supporting device mounted on a finishing floorboard, Fig. 2 is a plan view of the floorboard supporting device, Fig. 3 is a plan view of a bolt, Fig. 4 is a side view of the same, and Fig. 5 is a bolt end protection member. FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. 5, FIG. 7 is a plan view of a cylindrical body provided with a floor plate support plate, and FIG. 8 is a cross-sectional view taken along the line VIII-VIII in FIG.

A floor board support device A of the present invention is a bolt end protection member 2 placed on a structural floor 1 made of reinforced concrete, a bolt 3 fitted to the bolt end protection member 2, and a floor board receiving member screwed to the bolt 3. It has the cylinder 5 which projects the board 4.

As shown in FIGS. 5 and 6, the bolt end protection member 2 has a recess 2 a that fits into one end of the bolt 3, and is loaded via this bolt end protection member 2. The load is transmitted to the structural floor 1. As shown in FIGS. 3 and 4, a male screw 3a is threaded on the bolt 3 having one end fitted into the recess 2a of the bolt end protection member 2. Further, as shown in FIGS. 7 and 8, a female screw 5a is threaded over the entire length of the inner surface of the cylindrical body 5 which is screwed into the bolt 3. A disk-shaped floor plate receiving plate 4 is provided on the outer periphery of the side surface of the cylindrical body 5.

Next, a method of using the floor board supporting device A will be described. First, the bolt end protection member 2 is arranged at a predetermined position on the structural floor 1. The arrangement position of the floor board supporting device A will be described with reference to FIG. FIG. 9 is a layout view of the finishing floor board and the floor board supporting device arranged on the floor. The plurality of finished floorboards 6 cut into regular lengths are supported by the floorboard support device B for four sheets at the intersections where the four even-angled portions are joined, and the two even-angled portions are provided at the end of a wall or the like. The intersections where the two are joined are supported by the floor plate supporting device C for two sheets, and the independent corners are supported by the floor plate supporting device A of the present invention.

The bolt end protection member 2 is fixed on the structural floor 1 with the recess 2 a facing upward and the bottom surface 2 b coated with an adhesive. Next, the cylindrical body 5 projecting the floor plate receiving plate 4 is screwed into the bolt 3, and one end of this bolt 3 is fitted into the recess 2a of the bolt end protection member 2 to place the bolt 3 on the structural floor 1. Set up. Next, the cylindrical body 5 is rotated while using the level or the like to accurately adjust the support height H of the floor plate receiving plate 4.

On the other hand, the finishing floor plate 6 placed on the floor plate receiving plate 4 is provided with a mounting hole 6a into which the cylindrical body 5 is inserted. The finished floorboard 6 is mounted on the floorboard receiving plate 4 whose height has been adjusted by utilizing the mounting holes 6a, and then the filler 7 is inserted into the upper portion of the cylinder 5 of the mounting hole 6a.

[0017]

[Effect of the device]

 As described above, the floor board support device of the present invention supports the floor board and adjusts the height by the cylinder and the bolt protruding from the floor board support plate, so that the corner portion having a simple structure and a small load can be provided. Can be reliably supported. Therefore, it is possible to reduce the production cost of the floor board supporting device, and moreover, since it is lightweight, it is easy to lay the floor board.
