Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a double floor constructed by arranging a plurality of floor panels adjacent to each other on a reference floor surface, and more specifically, The present invention relates to an edge support device.

[Prior Art] When constructing a double floor constructed by laying a plurality of floor panels on a reference floor surface via support legs, the dimensions of the reference floor surface, which is the construction surface, are an integer of the dimensions of the floor panels. Since doubling is extremely rare and there are errors in construction, generally a gap with a width smaller than the panel dimension is created at the edge of the construction surface, that is, at the edge of the double floor.

In order to eliminate such voids, additional work is carried out using mortar or plywood, or floor panels are cut to fit the dimensions of the void and installed on site. When using cut floor panels, ie, cut panels, ordinary support legs cannot be used, so special support and fixing means are used.

Such a double floor edge support device supports the edge of a cut panel cut at an arbitrary position, so it is usually constructed separately from the floor panel and is height adjustable. In order to do this, a panel receiving member is screwed onto a support rod provided with a threaded portion.

[Problems to be Solved by the Invention] However, since the conventional double floor edge support device supports the panel receiving member with a single threaded rod, for example, it is difficult to butt two adjacent cut panels together. If one support leg is disposed below the cut panel to support these cut panels, the panel receiver will tend to tilt when an eccentric load is applied to the panel receiver, creating a step difference between adjacent cut panels. In addition, with conventional support devices, the cut panel is only placed on the support legs and is not fixed to the support legs, which is coupled with the fact that the width of the cut panel is smaller than that of a normal floor panel and its rigidity is lower. There also occurred a problem that the abutting portions of the cut panels tend to lift up.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to be able to support adjacent floor panels horizontally and without any difference in level, to reliably prevent the floor panels from lifting up, and to
To provide a double floor edge support device capable of supporting not only the edge of a cut panel but also the edge of a normal floor panel.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the double floor edge support device of the present invention provides a double floor edge support device that supports the lower reference floor surface of two adjacently arranged floor panels. an elongated support base fixed to and extending across two adjacent edges of the two floor panels; and the support bases are juxtaposed on the support base at intervals in the longitudinal direction, and at least two height adjustment bolts whose protrusion amount can be adjusted in the vertical direction; engaged with and supported by the heads of the height adjustment bolts;
and a panel support member extending across both bottom surfaces of the two floor panels, a panel support surface formed on the top surface of the panel support member, and the two panels placed on the panel support surface. and means for fixing the floor panel to the panel receiving member.

According to the double floor edge support device of the present invention having such a configuration, the elongated support extends across two adjacent edges of two adjacently arranged floor panels. The stand is fixed to a reference floor surface, and at least two height adjustment bolts are arranged in parallel at intervals in the longitudinal direction on this support stand, and the amount of protrusion of these bolts can be adjusted in the vertical direction. Because of this structure, even if an eccentric load is applied to the panel support member supported by these bolts, it will not tilt, and both panels can be supported horizontally without creating a step between two adjacent panels. I can do it.

In addition, the elongated support base to which the two height adjustment bolts are attached extends across the edges of the two adjacent floor panels, and has a sufficiently large contact area with the reference floor surface. Since the support base is fixed on the reference floor surface, it is possible to maintain a stable posture. In particular, even if an eccentric load is applied, this load is received by the entire support base and is distributed over a large contact area between the support base and the reference floor surface, so the support base will not tilt. . Furthermore, since this support has a considerable length in the longitudinal and width directions, even if there are small unevennesses (irregularities) on the reference floor surface, it will absorb these unevennesses and will not be affected by these unevennesses. It can be installed horizontally without any problems. Therefore, even when the height is adjusted by rotating the height adjustment bolt, the amount of adjustment can be made small.

Further, since the floor panel or cut panel placed on the panel support surface of the panel receiving member is fixed to the panel receiving member by the fixing means, it will not be lifted up even if a load is applied to the panel.

Since the panel is fixed to the panel receiving member by a fixing means, if a panel holder is used for this fixing means to prevent the panel from rising, it can be used to support the edge of a normal floor panel. can also be used.

Of course, a panel holding member 19 for supporting the cut side edge of the cut panel 2 as shown can be used.

[Effects of the Invention] As explained above, according to the double floor edge support device of the present invention, the height adjustment bolts are arranged to correspond to the corner parts of adjacent floor panels. This makes it possible to horizontally support the floor panel at a desired height.

Further, since the corner portions of adjacent floor panels are supported by the flat panel support surface, there is no difference in level between the floor panels.

Furthermore, since the floor panel supported on the panel support surface is fixed to the panel receiving member with screws, pressing members, etc., lifting of the floor panel is reliably prevented.

In addition, the elongated support base to which the two height adjustment bolts are attached extends across the edges of the two adjacent floor panels, and has a sufficiently large contact area with the reference floor surface. Since the support base is fixed on the reference floor surface, it is possible to maintain a stable posture. In particular, even if an eccentric load is applied, this load is received by the entire support base and is distributed over a large contact area between the support base and the reference floor surface, so the support base will not tilt. . Furthermore, since this support has a considerable length in the longitudinal and width directions, even if there are small unevennesses (irregularities) on the reference floor surface, it will absorb these unevennesses and will not be affected by these unevennesses. It can be installed horizontally without any problems. Therefore, even when the height is adjusted by rotating the height adjustment bolt, the amount of adjustment can be made small. In addition, compared to the case where two adjustment bolts are used to directly support the floor panel without using a support stand, the amount of adjustment of each adjustment bolt can be made smaller, which improves the workability of the floor panel. It also has the effect of improving.

Furthermore, the edge support device of the present invention can support not only the cut side edge of the cut panel but also the uncut edge of the floor panel, so it can be used as an edge support device for a double floor. Highly versatile.

Then, an opening is formed in the panel receiving member to expose the head of the height adjustment bolt, and a through hole that aligns with the opening is formed in the floor panel, and the bolt is rotated using a screwdriver inserted into the through hole. If configured to allow this, the height of the floor panel can be adjusted from above the floor after floor construction.
