Abstract

PURPOSE:To enhance the efficiency of setting out for a floor surface by laying long bars made of flexible materials and formed at opposite edges with engaging grooves, on a slab at predetermined intervals, and by laying strut members crosswise on these long bars so as to form a base, and by laying floor members on thus formed base. CONSTITUTION:Long bars 1 for forming a double flooring are made of a flexible plastic by extrusion-molding, and are formed at their opposite edges with U-shaped engaging grooves, marking being made at intervals of about 12.5cm on the outer surface of the long bars 1. Further, the long bars 1 are laid on a slab at intervals of about 12.5cm in parallel with one another. Further, struts 3 are crosswise laid on the long bars 1, regularly at center-to-center intervals of about 12.5cm. Then, floor plates 4 are laid on the bundles so as to form a floor base, and accordingly, a double flooring in which an under-floor space 6 is defined by the slab 5, the floor plates 4 and the struts is formed. Thereby it is possible to enhance the marking of the struts 3, and to expect a floor damping effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an underfloor space of a double floor.

[0002]

2. Description of the Related Art The method of mounting the four corners of a square floorboard in a bundle to form a double floor is very well known. In the case of constructing such a double floor, it is common to draw out the black ink on the floor surface in a grid pattern, form a bundle at each intersection, and erect the floor board on it.

[0003]

However, when the construction is carried out in this manner, marking the floor surface is troublesome. In particular, when supporting only the corners of a square floorboard, marking out is relatively easy, but when supporting the floorboard at more points, or when the floorboard is triangular, marking out is extremely difficult. Was troublesome. The present invention aims to improve upon such conventional methods.

[0004]

To this end, according to the present invention, a long member provided with one or a plurality of fitting grooves is laid on a slab so that a large number of fitting grooves are parallel to each other. A bundle having fitting portions on the bottom surface is fitted into the fitting groove at predetermined intervals, and the floor board is placed on the bundle.

[0005]

[Operation] If the long materials marked in advance at the place where the bundle is to be laid are laid at predetermined intervals, the place where the bundle is to be set is shown.
It is not necessary to mark the slabs one by one, and the construction is extremely easy. It is also convenient in that respect, as long materials can be fixed to the slab in places, and the bundles need not be fixed one by one.

Embodiment 1 An embodiment of the present application will be described in detail below with reference to the drawings. As shown in FIG. 2, the long member 1 is formed by extrusion molding a flexible plastic such as soft vinyl chloride. Both edges of the long material 1 are folded back in a U-shape and the fitting groove 1
1 is formed. Marks 12 are formed on the surface of the long material 1 at intervals of 12.5 cm. It is desirable that the fitting groove 11 is formed in the horizontal direction so that the fitting groove 11 will not easily come off when fitted as described below. As shown in FIG. 3, it is a thin band-shaped member, and locking hooks 2 are provided at both ends.
Form a spacer 2 labeled 1. As shown in FIG. 4, a rectangular thin plate made of a galvanized steel plate is press-molded to form a trapezoidal bundle 3. The size of the top of the bundle is 5 x 5
cm, height 5 cm, both lower ends of the bundle are bent outward to form fitting pieces 31. The upper surface of the bundle is covered with a flexible plastic cap 32 having a rectangular shape and curved edges. As shown in FIG. 5, a square floor plate 4 made of a galvanized steel plate having a thickness of 2.3 mm and having a side of 50 cm is formed.

For construction, as shown in FIG. 1, a plurality of elongated members 1 are laid in parallel on a slab 5. The laying interval is 12.5 cm, and the engaging hooks 21 of the spacers 2 are provided between the two adjacent strips 1 of the long strip 1 in the fitting groove 1 of the strip 1 of the strip.
Lock at 1 to define the spacing and keep parallel. Long material 1 is slab 5 with concrete nails 51 in places.
Fixed to. The adhesive may be applied to the back surface of the long material 1 and fixed. The long material 1 has a bundle 3 vertically and horizontally with a core of 12.5 cm.
Install at intervals. As for the installation method, the fitting pieces 31 of the bundle are fitted into the fitting grooves 11 of the long material. Since the long member 1 is made of flexible plastic, the mouth of the fitting groove 11 is widened to push the fitting piece. When the base on which the bundle 3 is regularly installed is completed, the floor board 4 is placed on the bundle 3 to form a floor base. In the case of placing, if the floor board 4 is placed so that the corner of the floor board 4 is positioned at the center of the upper surface of the bundle 3, a floor board of 50 cm square is 5 × 5 =
It is supported by a bundle of 25 pieces. Below the floor plate 4, an underfloor space 6 surrounded by the slab 5, the floor plate 4, and the bundle 3 is formed.

A trench floor plate 41 having a plane size of 50.times.25 cm is formed by using the same material as the floor plate, and as shown in FIG.
1 is installed continuously in a linear or cross pattern. Since the trench floor plate 41 is small and lightweight, it can be easily attached and detached, and wiring grooves and trenches can be easily formed. The width of the trench floor plate 41 may be narrower within the range where it can be placed on the bundle 3 and may be 12.5 cm. When forming a trench like this,
Since the general floorboard 4 is less likely to be attached and detached, the floorboard 4 may be fixed to the bundle 3 by a method such as gluing. The material of the floor plate is not limited to a steel plate, and may be cement-based, wood-based, or the like as long as it is flat and has strength enough to be used as a floor plate.

As shown in FIG. 7, as the long member 1, a wide member having a plurality of pairs of fitting grooves 11 may be used.
If the long material 1 has a width of 50 cm and is laid on the entire surface of the slab, the construction can be further simplified, and since the entire slab 5 is covered, it is convenient for protecting the wiring. After forming the long material 1 of the same size as the floor board, as shown in FIG. 8, it is attached to the back surface of the floor board 4, and the bundle 3 is fitted into the fitting groove 11 of the long material on the back surface at the site. , Laid on the slab 5 to make a double floor,
It is also possible to form the underfloor space 6. Although the long material 1 is not limited, extrusion molding is optimal for producing a long material having a pair of fitting grooves.
Further, it is most suitable to use plastic as a material, but it does not prevent the use of an aluminum extruded product or the like. As shown in FIG. 9, the long member 1 may be used as a pair by combining two members each having one fitting groove 11.

The material and shape of the bundle 3 are not specified in the above embodiment. For example, as shown in FIG. 10, a bundle 3 formed by drawing a thin plate of iron or aluminum into a cup shape has a very high pressure resistance even for a thin plate and is suitable for weight reduction. An edge is attached to the cup to form the fitting piece 31. In addition, a plastic with high strength and rigidity is used as a material, and is extruded to obtain
It is also possible to use a trapezoidal bundle 3 as shown in FIG. It is suitable for mass production because it can be obtained by cutting an extruded product into short pieces.
