[0001]

BACKGROUND OF THE INVENTION The present invention relates to a double floor in which a large number of floor panels are arranged and laid on a floor base made of concrete or the like with a space at an appropriate height. The present invention relates to an improvement in a device for supporting a floor panel.

2. Description of the Related Art As a supporting device for a floor panel in a double floor of this kind, Japanese Utility Model Laid-Open Publication No. 3-73345 discloses a prior art in which rows of adjacent floor panels are arranged on the upper surface of a floor base. A strip-shaped base body is installed in the space between the floor panels so as to extend along the row direction of the floor panel, and one joist member formed in a rail shape is mounted on the base body via an adjuster bolt. The joist member supports one side of the floor panel at one longitudinal side edge, and the other joist member at the other longitudinal side edge supports the side edge of the other row floor panel. In addition, an adjuster bolt adapted to contact the base body is provided at an appropriate interval along the longitudinal direction also at one longitudinal side edge and the other longitudinal side edge of the joist member. Is described. Japanese Utility Model Laid-Open No. 3-15943 discloses a configuration in which each grounding body is provided with only an adjuster bolt for directly supporting a floor panel.

According to these prior arts, the height of a large number of floor panels can be simultaneously adjusted by changing the height of a joist member with an adjuster bolt. In addition, by providing adjuster bolts that contact the base body at one longitudinal edge and the other longitudinal edge of the joist members, the load on each floor panel can be adjusted with the adjuster bolts. Since it can be directly supported, there is an advantage that the stability of the floor panel can be improved. However, on the other hand, in a configuration in which two rows of floor panels are commonly supported by one joist member as in this prior art, the distance between adjacent rows of floor panels is reduced. As the width increases, the width of the joist member and the base body must be correspondingly increased.Therefore, if the distance between adjacent floor panels increases, the supporting device becomes extremely large, and handling of the joist member and the base body becomes remarkable. In addition to being bothersome, the use of more materials than necessary makes them heavier and produces multiple types of joist members and bases with different widths depending on the spacing between adjacent floor panels. Therefore, there is a problem that a great deal of labor is required for manufacturing and management. The purpose of the present invention is to solve this problem.

In order to attain this object, the present invention provides a method for laying a large number of floor panels in a line above a floor base with a space at an appropriate height. In the double floor, on the floor base, common grounding members common to rows of adjacent floor panels are installed at appropriate intervals along the row direction of floor panels, and A pair of left and right joist members that individually support two rows of floor panels are removably attached to each of the right and left joist members via adjuster bolts in a height-adjustable manner. A connecting body that overlaps the left and right joist members is inserted and disposed, and each of these connecting bodies is removably fastened to the left and right joist members with bolts and nuts. " Further, in claim 2, in claim 1, each connecting body is arranged at each location of each grounding body, an adjuster bolt is penetrated through the joist member and the grounding body, and an adjuster bolt and a nut screwed to the adjuster bolt are used. The left and right joist members and the connecting members are integrally fastened.

[Operation and effect of the invention] With this configuration, the left and right joist members and the connecting member can be separated separately, so that the members can be easily carried before construction, and the distance between the left and right joist members is defined by the connecting member. Therefore, the assembling work for connecting the left and right joist members is simple. Further, by adjusting the height of each joist member, the heights of a large number of floor panels can be made uniform at the same time. In this way, the members are easy to carry, and the assembling work is simple,
In addition, the height adjustment of a large number of floor panels can be performed at the same time, so that the floor panel laying operation can be performed efficiently. Further, since the left and right joist members are integrally connected by a connecting body screwed to the joist member, the row of floor panels is supported by separate joist members while the floor panels are kept in a stable state. Can be supported. In other words, the support strength of the floor panel does not decrease. Furthermore, the width of the joist members can be made the same regardless of the width of the interval between the adjacent floor panels. In other words, even if the size (width dimension) of the supporting device is different, the long joist members are long. Can be shared, and it is sufficient to prepare multiple types of linked bodies with a short length.As a whole, the labor required for manufacturing, storage and management can be reduced, and the distance between the left and right joist members can be increased. Even if the stability is increased, the weight can be reduced by eliminating the loss of the material. Therefore, according to the present invention, the load required for manufacturing, storing and managing the joist members can be reduced and the weight can be reduced without lowering the efficiency of the laying work and lowering the support strength of the floor panel.
Further, according to the second aspect of the present invention, since the connecting body and the joist member can be fastened using the adjuster bolt for height adjustment, the number of parts is reduced, and the burden required for manufacturing, storing, and managing the member is reduced. In addition to being able to further reduce, the joist member, the connecting body and the adjuster bolt are in a state of being reinforced with each other, so that there is an advantage that the rigidity of the supporting device can be further improved and the supporting strength of the floor panel can be further improved.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a double floor. In the figure, reference numeral 1 denotes a rectangular floor panel in plan view, which is laid vertically and horizontally above a concrete floor base A, and reference numeral 2 denotes The support device for supporting each said floor panel 1 is each shown. 2 is an exploded perspective view of the support device 2, FIG. 3 is a partially cutaway perspective view of the double floor, FIG. 4 is a plan view of the double floor, FIG. 5 is a cross-sectional view taken along line VV of FIG. 4, and FIG. 4 is a sectional view taken along line VI-VI, FIG. 7 is a sectional view taken along line VII-VII of FIG. 4, and FIG.

The left and right fitting portions 9a of the connecting body 9 are arranged so as to extend over two floor panels 1 adjacent to each other in a plan view, as shown in FIGS. 2, 5, 6, and the like. At the front and rear ends of the fitting portion 9a, positioning pieces 19 for the crossing side edges of the corners of the floor panel 1 are provided to project upward. As shown in FIGS. 1, 3, and 4, a gap between adjacent floor panels 1 is closed by a cover body 21. For example, as shown in FIG. 3, the cover body 21 has both left and right long side edges bent in a U-shaped cross section, and is placed on the flange portion 6 of the floor panel 1. As shown in FIG. 5, an elastic body 22 such as a rubber plate is interposed between the left and right side edges of the cover body 21 and the flange portion 6 of the floor panel 1 for soundproofing.
A gap is provided between the cover body 21 and the connecting body 9 so that a cord 23 for power supply or communication can be inserted. In addition,

The four cover bodies 21 are pressed and fixed by one auxiliary cover body 24 by screwing a screw 26 penetrating the auxiliary cover body 24 into the female screw hole 25 from above. .
For example, as shown in FIG. 1, on the side edge of the auxiliary cover body 21, a foot piece 24b that contacts the flange 6 of each floor panel 1 is formed by bending. As means for pressing and fixing each cover body 21 to the floor panel 1 via the auxiliary cover body 24, a screw
Instead of screwing the screw 26 into the female screw 25 of the adjuster bolt 13, the screw 26 may be screwed into the connecting member 9 or the screw 26 may be screwed into the joist member 8 as shown in FIG.
Reference sign B shown in FIGS. 5 to 7 is a rug such as a carpet.
In the above configuration, since the rows of the adjacent floor panels 1 are supported by the separate joist members 8, the long joist members 8 are of the same type even if the size (width dimension) of the support device 2 is different. Since things can be shared, the labor of manufacturing, storage and management can be reduced accordingly. Further, since the left and right joist members 8 are integrally connected by the connecting body 8, the rigidity of the supporting device 2 can be maintained in a high state while the two joist members 8 are separate bodies. The floor panel 1 can be supported in a stable state without rattling or shaking movement. Since the connecting body 9 and the left and right joist members 8 are fastened together via the adjuster bolts 13, the number of parts can be reduced, and the left and right joist members 8, the adjuster bolts 13 and the connecting body 9 are integrated. The support device 2
Can be further improved. Further, since the interval between the left and right joist members 8 can be increased, the stability of the support device 2 can be increased without increasing the weight. The room is air-conditioned using a double floor. This point will be described with reference to FIGS. 1, 4, 10, and 11 (FIG. 10 is a sectional view taken along line XX of FIG. 4).

Among them, an arbitrary cover body 21 is provided with a vent hole 27 having a circular shape in plan view. The conditioned air is filled into the space between the floor base A and the floor panel 1 and then guided to the ventilation hole 27, or is guided to the ventilation hole 27 via the duct 31. By bending the inner peripheral edge at the inner peripheral edge of the vent hole 27 to form a radially inward step 27a, a joint 29 for guiding the conditioned air to the air conditioning unit 28 also serving as a partition panel is formed in each vent hole 27. When,
A plug 30 for closing the ventilation hole 27 can be detachably mounted. The joint 29 is formed in a cylindrical shape so as to be rotatable in the vent hole 27, and has a rectangular ejection hole 29a in a plan view that fits into the space of the air conditioning unit 28 from below at the upper end thereof. I have. Reference numeral 28a indicates a baseboard of the air conditioning unit 28. When the conditioned air below the floor panel 1 is guided into the air conditioning unit 28 via the joint 29 formed in this manner, even if the width of the air conditioning unit 28 is smaller than the width of the cover body 21, The attitude of the air conditioning unit 28 can be freely changed. When the conditioned air is blown into the room from the air conditioning unit 28, it is needless to say that the blowout position can be arbitrarily set, and may be blown out from a portion of the baseboard 28a as indicated by a dotted arrow in FIG.
