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. It is extremely rare for the product to double, and there are construction errors, so
Generally, a gap having a width smaller than the panel size 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 support member with a single threaded rod, for example, when two adjacent cut panels If a single support leg is disposed below the abutting portion to support these cut panels, when an eccentric load is applied to the panel receiving member, the panel receiving member is likely to tilt, creating a step difference between adjacent cut panels. In addition, with conventional support devices, the cut panels are only placed on the support legs and are not fixed to the support legs, which is also compatible with the fact that the width of the cut panels is smaller than that of a normal floor panel and the rigidity is lower. As a result, a problem arose in that the abutting portions of the cut panels tended 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 support not only the edges of cut panels but also the edges of ordinary floor panels. An object of the present invention is to provide a double-bed edge support device capable of supporting even the edges.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the double floor edge support device of the present invention includes a support base fixed to a reference floor surface, and a support base fixed on the support base. , and at least one pair of height adjustment bolts that are expandable and retractable in the vertical direction, and both bottom surfaces of two adjacent floor panels that engage with and are supported by the heads of the height adjustment bolts. a panel support member extending over the panel support member, a panel support surface formed on the upper surface of the panel support member, and means for fixing the floor panel placed on the panel support surface to the panel support member; It is characterized by having the following.

According to the double floor edge support device of the present invention having such a configuration, since the panel receiving member is supported by at least a pair of height adjustment bolts, even if an eccentric load is applied to the panel receiving member, the panel receiving member does not tilt. Both panels can be supported horizontally without creating a difference in level between two adjacent panels.

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 lifting up, it can also be used to support the edge of a normal floor panel. can.
