Abstract

PURPOSE:To remarkably increase the degree of freedom of height adjustment of a floor plate, by fixing a base having a high space on a slab and fitting with a screw a floor plate supporter having a fixed bolt for vertical adjustment through a supporting member. CONSTITUTION:A floor plate 4 is placed on a height-adjustable base in which a square cylindrical base 1 provided with an opening 10 and an insertion hole 14 and a circular support plate 3 fixed with a bolt 31 are connected with screws through a supporting member, to constitute a double floor. A washer 33 is fitted to the support bolt 31 to hold the base plate of the base 1. And this is fastened by the upper support nut 32 and the lower fixing nut 34 to form the support member. The opening 10 is provided at the lower side face of the base 1 and a space is given under the base 1. In this way, the bolt 31 is moved while the fixing nut 34 is rotated to adjust the position of the support plate 3. As a result, the height-adjustable range can be increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjusting method for a double floor.

[0002]

2. Description of the Related Art Conventionally, nuts are embedded in the four corners of a floor plate of a double floor, bolts are screwed into the nuts, and the bolts are rotated to adjust the height. In this case, the width of height adjustment was very limited unless the nut was made long or the nut was not installed at a low position.
In addition, if a slender joist is supported by a single bolt, there is a drawback that it will always roll and become unstable.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem. Therefore, in the present invention, a base having a through hole on the upper surface is installed on the floor surface, a bolt is vertically penetrated through the through hole, and the nut is screwed on both the upper and lower surfaces so as to sandwich the board. Thus, the object to be supported is fixed to a desired height and the supported body is supported on the upper end of the bolt. Further, in order to stabilize the lateral direction, in the present invention, a plurality of through holes are provided in the base to fix a plurality of bolts, or a plurality of bolts are fixed using a base connected at a predetermined interval. , The upper joist is supported by a plurality of bolts.

[0004]

Since the present invention is constructed as described above,
Since the space under the base is the height adjustment width, the adjustment width can be increased. Also, by taking a wide bottom surface of the base or by using a plurality of bolts, it is possible to prevent the lateral slings of the slender joists.

Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIG. 1, a short rectangular cylindrical base 1 is formed of a galvanized steel sheet and having an opening 10 oriented in the lateral direction. A narrow gap 12 is opened on the bottom surface 11 of the base 1. A through hole 14 having a diameter of 2 cm is opened in the center of the flat substrate 13 having an upper surface. All anchors 2 in the gap 12
The base 1 is fixed at a predetermined position of the slab 2 by driving 1. A buffer plate 22 is sandwiched on the bottom surface of the base.

A support nut 32 is screwed onto a bolt of a circular support plate 3 having a bolt 31 vertically attached to its bottom surface, and a washer 33 is fitted and inserted into the through hole 14 of the base. From the lower side of the bolt 31, the washer 33 is fitted and the fixing nut 34 is screwed. By rotating the support nut 32, the support plate 3 is moved up and down, and the fixed nut 34 is moved at a predetermined height.
The bolt 31 is fixed to the board 13 by firmly tightening and pinching the board 13 between the two nuts. Since the opening 10 is provided on the lower side surface of the base 1, the fixing nut can be turned from the opening 10. Also, since the through hole 14 is made large, the position of the support plate 3 can be adjusted by moving the bolt 31 therein. The floor board 4 is mounted on the height adjusting table thus formed to form a double floor.

When the slab 2 is not horizontal, the bolts 31 can be installed vertically by placing the tapered washer 35 on the base 1 as shown in FIG. 2 to make the base 1 horizontal. it can. A plurality of taper washers may be stacked and used. It is also possible to put a plate with a taper under the base to make it horizontal. It is also possible to insert a cushioning plate between the base and the washer on the base for vibration prevention and noise reduction.

[0008]

[Embodiment 2] As shown in FIG. 3, a wide base 1 having a U-shaped cross section made of a galvanized steel plate and having one through hole 14 on each of both sides of the upper surface is arranged at intervals of 50 cm. Glue and fix it on the slab 2 in parallel. A small hole 15 is provided on the bottom surface of the base 1 so that the glue is easily entangled. Bolts 31 are vertically joined at 50 cm intervals to the bottom surfaces of the support edges 51 on both sides of a long joist 5 made of a galvanized steel plate and having a hat-shaped cross section. A support nut 32 is screwed onto the bolt 31, a washer 33 is fitted, and then inserted into the through hole 14 on the base 1.

The support nut 32 is adjusted to bring the level of the joist 5 into horizontal alignment. The washer 33 is fitted into the bolt 31 from the lower side of the base 1, and the fixing nut 34 is securely tightened to fix the joist 5 to the base. The nuts may be applied with a loosening prevention resin or the like, or it is preferable that the nuts are fixed and then the adhesive is injected into the gap between the bolt and the nut to prevent the nut from loosening. By such a method, a plurality of joists are fixed on the slab at a predetermined interval to form a height adjusting table, and the floor board 4 is installed between the opposing supporting edges to form a double floor.

[0010]

Third Embodiment FIG. 4 shows a method of forming the wiring pit 6. The galvanized steel strip is bent to form a connecting base 18 in which two hat-shaped bases 1 are connected by a connecting plate 16. Through holes 14 are provided in the substrate 13 of each base 1, and anchor holes 17 are provided in the connecting plates 16 on both sides of the base 1. After marking out points on the slab 2 to form pits, the connecting bases 18 are fixed at predetermined intervals. Concrete nail 2 through anchor hole 17
Hit 4

A rod-shaped support frame member 60 having a rectangular tubular cross-section formed by aluminum extrusion is formed. Support frame material 6
A horizontal lid receiver 61 is attached to the lower edge of one side of 0. Bolts 31 are attached to the bottom surface of the support frame member 60 at predetermined intervals. Each bolt 31 is loaded with a support nut 32 and a washer 33, and then inserted into the through hole 14 formed in the substrate 13 of the base 1. From the bottom of the board 13, washers 3
3. Screw the fixing nut 34. By operating the support nut 32 as in the above-described embodiment, the fixing nut 34 is tightened to fix the support frame member 60 on the connection base 18 when the two support frame members 60 are parallel and level. To form a height adjustment stand.

A lid plate 62 made of a reinforced cement plate and having the same thickness as the depth of the lid receiver 61 of the support frame member is provided between the lid receivers 61 to form the wiring pit 6. The cover plate 62 is supported by the support frame members 60 on both sides, and can be easily attached and detached.
You can easily communicate with the upper space.

[0013]

Since the present invention is constructed in this way, it has the following features. (1) It is possible to increase the width of height adjustment by setting the space under the base to be high. (2) Since the bottom surface is supported by a wide base, it is stable. (3) If the base is fixed to the floor surface, the base and the supported body are connected with bolts, so the supported body can be indirectly fixed to the floor surface. It is stable even when used. (4) Since the base can be widened to receive a plurality of bolts, and the intervals and angles between the bolts can be defined by a method of connecting a plurality of bases, the dimensional stability is good. (5) A taper washer and a cushioning material can be inserted between the washer and the base, which is convenient.
