Description

[Detailed Description of the Invention] [Industrial field of application] The present invention comprises a floor panel laid on a floor substrate with appropriate vertical gaps, supported by a plurality of joist members extending in parallel with each other. The present invention relates to improvement of a support device for this floor panel in a double floor.

[Conventional technology]

In this type of double bed, Japanese Patent Laid-Open No. 1-
In 165869, a joist member is formed in a groove shape having an upward U-shaped cross section, and an adjuster bolt is directed downward at the lower end of a panel seat body having an upward U-shaped groove for supporting each joist member. The floor panel is fixed by the left and right flange portions of the panel seat body, and the lid body (joint member) is arranged along the upper side of the joist member between the sides of the adjacent floor panel. It is disclosed.

Further, in JP-A-1-304260, the bottom piece of the joist member having an upwardly U-shaped cross section is supported on the floor surface by an adjuster bolt, and the adjuster bolt is connected to the joist member by a spacer orthogonal in a plan view. The engaging grooves that are opened downward are fitted to the upward vertical pieces of the left and right joist members and the downward vertical pieces of the downward U-shaped floor material.

Further, in Japanese Utility Model Laid-Open No. 59-106955, both members are arranged orthogonally to each other in a plan view so that a channel member having a downward U-shaped cross section is supported by a joist member having a rectangular band cross section.
While the joist member is supported by the adjuster bolts, the floor panels placed on the top surface of the channel member have no adjacent gaps, and the four corners of the four floor panels are joined together. The member is connected with a bolt and a nut.

[Problems to be solved by the device]

According to the prior art of Japanese Patent Laid-Open No. 1-165869, joint members are arranged between floor panels adjacent to each other on the left and right sides, and wiring can be inserted along the joist member. However, even if the joint member is removed, the adjuster bolt at the lower end of the panel seat body cannot be turned from above the joist member, which makes it difficult to adjust the height of the floor panel. JP 1-3042
Even with the devices disclosed in Japanese Laid-Open Patent Publication No. 60 and Japanese Utility Model Laid-Open No. 59-106955, the adjuster bolt cannot be adjusted without removing the floor panel, and the above inconvenience cannot be solved.

The present invention has been made to solve the above problems, and it is possible to easily adjust the height of a floor panel without impairing the aesthetic appearance, and to easily insert a wiring cord. An object of the present invention is to provide a support device for a floor panel in a heavy floor.

[Means for solving the problem]

In order to achieve the above-mentioned object, the floor panel supporting device in the double floor of the present invention has an outwardly facing stepped portion at the lower part of the four side edges of the floor panel which is laid on the floor substrate so that an appropriate gap is provided vertically. Between the adjacent floor panels, the floor panels are detachably mounted on the upper surface of the stepped portion of each floor panel across a joint member having a downward U-shaped cross section that is substantially level with the upper surface of the floor panel. While forming a gap to be placed, the lower surfaces on the left and right sides of the adjacent floor panels are supported by a plurality of joist members extending in parallel with each other and having an upwardly U-shaped groove below the joint member. , The lower surface of each joist member is supported by a longitudinal support plate extending in a direction intersecting with the longitudinal direction of the joist member in a plan view, and an intersection portion of each joist member and the longitudinal support plate is formed of the joint member. Set so that it is on the lower side, and at each front intersection, the root The groove member, bored a hole in which adjuster bolt penetrates vertically, the longitudinal support plates, is obtained by the configuration in which the lower end is screwed to abut adjuster bolt to the floor substrate.

[Operation / Effect of the Invention] With this configuration, the upper portion of each adjuster bolt screwed to the longitudinal support plate penetrates each joist member, so that the distance between the adjacent parallel joist members becomes long. It is regulated constantly by the support plate, in other words, the longitudinal support plate also has a function of connecting the adjacent joist members to each other, so that the parallel positioning of the adjacent joist members can be performed extremely quickly. Therefore, the efficiency of installation work of the joist member is not reduced.

An outward step is formed at the bottom of the four-side edge of each floor panel, and the joist member has an upward U-shaped groove at the center in the width direction. Then, between the adjacent floor panels placed on the parallel joist members adjacent to each other, on the upper surface of the stepped portion of each floor panel, a downward U-shaped cross-section having substantially the same height as the upper surface of the floor panel. Since it is removably placed across the joint member in the shape of a joint, the intersection of each joist member and the longitudinal support plate and the upper side of the joist member will be covered with the joint member, so if the joint member is removed, Since the upper end of the adjuster bolt appears in the groove portion of the joist member at the crossing portion, it is possible to adjust the height of the longitudinal support plate, and thus the height of the joist member, very easily by rotating the upper end.

Since the joint member is covered with the joint member after the adjustment, the appearance of the floor device is not impaired, and since the joint member is almost at the same height as the upper surface of the floor panel, there is an effect that unevenness does not occur in the floor device. .

Further, since the joint member is removably placed on the upper surface of the stepped portion of the adjacent floor panels, when the joint member is removed, a gap between the adjacent floor panels can be formed above the joist member. Also, there is an effect that a wiring cord can be inserted at that location.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 is a floor panel in which a large number of floor panels are arranged above the floor substrate A by vertically and horizontally aligned with a proper gap, and reference numeral 2 is a joist member made of a metal plate for supporting each floor panel 1. Each of the floor panels 1 has a step portion 3 formed on the four circumferences thereof, and the step members 3, 3 of the adjacent floor panels 1, 1 are provided with a joint member 4 having a U-shaped cross section. It is placed (see Fig. 3). Then, the upper surface of the joint member 4 is set to be substantially level with the upper surfaces of the adjacent floor panels 1, 1 (see FIG. 3).

Each joist member 2 has an upward U-shaped groove portion in the center portion in the width direction, so that the joint member 4 can be arranged above the groove portion. In addition, between the bottom surfaces of the adjacent joist members 2, a longitudinal support plate 5 extending orthogonally to both joist members 2 is provided between the adjacent floor panels 1 at an interval twice the installation interval of the floor panels 1. Are arranged so as to be located in the space of the longitudinal support plate 5, and both ends of the longitudinal support plate 5 are brought into contact with the lower surface of the floor joist member 2, respectively, and female screw holes 6 formed at both ends of the longitudinal support plate 5 are provided.
An adjuster bolt 7 having a driver engaging means such as a minus groove is screwed into the upper end of the adjuster bolt 7, while a through hole 8 through which the adjuster bolt 7 penetrates is formed in each joist member 2. Is configured to be rotatable from above.

In the above structure, the adjuster bolts 7 are screwed to the longitudinal support plate 5, and it is sufficient to form the through holes 8 in each joist member 2, and it is not necessary to attach a nut to each joist member 2. The structure of the supporting device as a whole can be simplified, and the processing cost can be reduced. Moreover, since the entire lower surface of each joist member 2 is supported by the longitudinal support plate 5, the longitudinal length of the joist member 2 can be reduced. Even when the floor panel 1 is supported at the side edge portions, no bending moment is applied to both longitudinal edges of the joist member 2 and the joist member 2 is not flexibly deformed. Can be improved without increasing the thickness of the joist member 2.

Then, the adjuster bolts 7 screwed to the longitudinal support plates 5 are passed through the through holes 8 of the joist members 2, so that the distance between the adjacent joist members 2 is uniformly regulated by the longitudinal support plates 5. Therefore, the joist members 2 can be positioned extremely quickly, and the joist members 2 can be installed efficiently.

In the above-described embodiment, the one long supporting plate 5 supports the two joist members 2, but the one-dot chain line 5a is shown in FIG.
As shown in, one long support plate 5 is formed long so as to straddle three or more joist members 2, and one long support plate 5 supports three or more joist members 2. Is also good.

If the joint member 4 above the joist member 2 is removed, a gap is created between the upper surface of the joist member 2 and the adjacent floor panels 1 and 1. Therefore, a wiring cord may be inserted along this gap. Also, if the joint member 4 along the upper part of the longitudinal support plate 5 is removed, the gap between the adjacent floor panels 1 and 1 continues to the floor substrate. Therefore, insert the wiring cord into the gap. It can also be done.
