Abstract

PURPOSE:To make constructing operation of double floors easier by a method in which cross-shaped cutting lines are provided for floor panel, and the floor panel is easily divided on the construction site to form two or four square pieces and the pieces are placed on corners and wall sides in such a way as to match the corners of four floor panels. CONSTITUTION:A styrene sheet formed by vacuum moulding is divided into four square pieces each of which has a hollow projection, and a crossshaped cutting line is formed on the central part of the piece. These pieces are placed on corners 4 and wall sides 5 of the floor 3, where one section divided into four parts along two cutting lines is used for the corners 4 of room and the adjacent two sections are used for the wall sides 5, Afterwards, undivided pieces are placed at equal internals and a square floor panel 2 of galvanized steel plate is placed on them by matching the corners of the panels 2. Wiring and piping are set in the space between the floor 3 and the floor panel 2. The floor panel 2 can be easily detached and the wiring operation in the space can also be easily attained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footboard used for forming a double floor.

[0002]

[Prior Art and Problems] The inventors of the present invention filed No. 0 in 1986.
No. 76184, the title of the invention "wiring floor structure", a plurality of footboards of the same height are laid on the floor surface, and the abutting portions of the corners of the floorboards laid between the footboards are placed on the footboard. We proposed a wiring floor in which floor boards are laid in a suspended state. This method is simple and inexpensive, but the problem is construction on the wall or in the corner of the room. At the edge of the wall, a part of the footboard protrudes from the edge of the floorboard, which has the drawback that the floorboard cannot be spread all the way to the wall. For this reason, it is necessary to prepare a special member for the border, the number of members increases, the manual becomes difficult, and skill is required for construction.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem. Therefore, in the present invention, the footboard can be easily divided even at the construction site along the two orthogonal straight lines forming the sides of the four floor boards to be placed.

[0004]

Since the present invention is constructed as described above,
I cut half of the footboard near the wall, and in the corner of the room,
By cutting off the outer three-quarters, there is no part that protrudes from the floorboard, so the floorboard is spread.

[0005]

Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIG. 2, a polystyrene sheet having a thickness of 2 mm is vacuum-formed to form a footboard 1 having a side length of 20 cm, which is provided with square hollow convex portions 11 having a height of 3 cm and a total of four vertical and horizontal sides. A ten-character cutting line 12 is marked in the vertical and horizontal centers.

As shown in FIG. 3, a galvanized steel plate having a thickness of 2.3 mm is press-pressed to form a square floor plate 2 having a side of 30 cm.

As shown in FIG. 1, the floor 3 has a corner 4 of the room,
Lay out the footboard 1 from the edge 5 of the wall. Footboard 1 in corner 4 of the room
Is divided into four along two cutting lines 12, and at the wall edge 5, the footboard 1 is divided into two along one cutting line 12. After that, the standard feet 1 may be laid at equal intervals. After laying the feet 1 on the floor 3 in this way,
The footboard 1 is spread so that the corners of the floorboard 2 are placed on the footboard 1 to form a double floor. As shown in FIG.
In the meantime, a space 6 can be formed between the floor surface 3 and the floor plate 2. This space 6 is used for wiring and piping. By attaching and detaching the floor plate 2, it is convenient to work in this space.

[0008]

Example 2 As shown in FIGS. 5 and 6, a block-shaped footboard 1 having a side of 20 cm and a height of 5 cm is formed using a Styrofoam resin molded product. The upper surface of this block-shaped footboard is divided into three thin and deep grooves 13 at equal intervals vertically and horizontally.
16 small blocks 14 are provided at the top by this groove.
It is divided into The footboard is formed along the groove 13 using a simple cutter so that the footboard can be divided. A thin partition plate 15 having a cross-shaped cross section is formed by extrusion molding of plastic. The partition plate 15 is inserted into the groove 13 at the center of the block-shaped foot plate. The partition plate 15 is protruded from the upper surface of the footboard by the thickness of the floor plate, that is, 2.3 mm. A double floor is constructed in the same manner as in Example 1 by using such a block-shaped footboard 1. When the floorboards 2 are laid out and arranged so that the corners of the floorboards match the inner angles of the partition board 15, lateral movement of the floorboards can be suppressed, and the corners of the floorboards do not collide with each other, so that no sound is generated, which is convenient. Is. The footboard of the present invention may be used in combination with an auxiliary support stand for supporting the floor board. It is also possible to make the bottom sheet of the footboard larger and spread the sheets so that they are adjacent to each other.

Since the present invention is constructed as described above, it has the following features. (1) When laying the footboards 1 apart, if some footboards are divided along the cutting lines or grooves at the corners / walls of the room, it is not necessary to prepare special members for corners / walls. (2) A double floor can be formed simply by laying the floor boards on the floors laid side by side, and the wiring / piping space can be accessed by attaching and detaching the floor boards, so that it can be used later for wiring work, etc. Easy to do. (3) Since the floorboard is easy to construct, it is not troublesome to make the floorboard small. Therefore, unlike the large floorboard, the floorboard easily fits in even if there is some unevenness on the floor surface. (4) If a cross-shaped protrusion is attached to the center of the footboard, the work of installing the floorboard is easy and there is no lateral movement or collision of the floorboard, which is convenient.
