Description

[Detailed description of the invention] This invention relates to a floor sanderch panel used, for example, as a floor panel for physical education laid over a swimming pool. This invention relates to an improvement of a sanderch panel for a floor, which is filled with a foam core material and has an anti-slip sheet on the upper surface plate.

As shown in FIG. 1, this type of conventional sanderch panel has a pair of upper and lower rectangular surface plates a and b.
A foam core material c, such as polyurethane, is filled in between, and the peripheral bent edges a', b' of the surface plates a, b are formed by crimp pieces e provided on a peripheral frame d arranged at the peripheral edge of the core material c. was clamped and fixed, and further held by anti-slip sheet protection protrusions g disposed on the upper surface plate a. A large number of them were laid on a support member h via spacers i, etc., and were used as floor panels for physical education and the like.

In the conventional panel configured as described above, since the peripheral frames d and d are joined at right angles to each other at the corners, as shown in FIGS. 2 and 3, both ends of each peripheral frame d are The crimp piece e is cut at an angle of 45 degrees, a notch g' is made in a part of the protrusion g for roll relief, and after joining both peripheral frames d and d, the crimp piece e is It was necessary to bend the surface plates in stages and clamp and fix the surface plates a and b (see Fig. 1). Moreover, during the rolling process, the end e' of the crimp piece e on one of the peripheral frames d is bent in advance, and finally the ends e', e' of the crimp pieces e, e on both the peripheral frames d, d are bent. Pre-cut diagonally to avoid overlapping
It required a lot of time and skill to process, such as having to do "e''. Also, since the top and bottom shapes of the peripheral frame d were different, it was necessary to pay attention to the mounting position during assembly work.

Therefore, in conventional panels of this type,
A large number of notches are required, and two-step roll processing is required for bending the crimp piece e, which requires a large number of assembly steps and processing time. Furthermore, since the crimp piece e and the protrusion g for protecting the anti-slip sheet protrude, a plywood such as a plywood board is required when filling the foam insulation material c.
Furthermore, during use, since the notch g' at the end of the protrusion g is exposed, there is a problem of lack of safety, such as the anti-slip sheet turning over and causing injury.

This idea was made in view of the above circumstances,
The purpose of this is to be able to reliably join and fix the surrounding frames to each other and the surrounding frame and the surface plate with simple processing, and to facilitate the foaming work of the core material due to the flat upper and lower surfaces. An object of the present invention is to provide a sanderch panel for a floor, which is characterized by being able to improve safety during use.

That is, the gist of this invention is to provide a sanderch panel for a floor comprising a foam core material filled between a pair of upper and lower rectangular face plates, and an anti-slip sheet provided on the upper face plate. A peripheral frame made of a substantially U-shaped cross section with both ends cut at an angle of 45 degrees is arranged around each edge of the surface plate, and in grooves symmetrically provided on the upper and lower surfaces of this peripheral frame, the This invention relates to a sanderch panel for a floor, which is formed by inserting a peripheral bent edge of a surface plate and pressing and fixing it with a pressing strip having a wedge-shaped cross section. Embodiments of this invention will be described below with reference to FIGS. 5 to 8.

5 and 6 are a sectional view and an exploded perspective view of the sanderch panel 1 in an assembled state, respectively, showing the first embodiment of the sanderch panel of this invention.The structure of the main part of the sanderch panel 1 is rectangular as in the conventional structure. A foam insulation material such as polyurethane is filled in a space surrounded by a pair of upper and lower surface plates 2 and 3 and a peripheral frame 4 arranged between and around each edge of these surface plates 2 and 3. It is composed of a core material 5 and an anti-slip sheet 6 laid on the upper surface plate 2.

Sanderch panel 1 configured as above
In this case, the peripheral frame 4 is formed of an aluminum section having a substantially U-shaped cross section cut at 45 degrees at both ends thereof, and the peripheral bent edges 2a of the surface plates 2 and 3 are formed on the upper and lower surfaces thereof. A first groove 7, 7 having an expanding taper portion into which the groove 3a is inserted, and a second groove 8, 8 having a cross-sectional shape located in parallel on the outside of the first groove 7 are provided symmetrically. There is. Then, the peripheral bent edges 2a, 3a of the surface plates 2, 3 are inserted into the first groove 7, and a pressing strip 9 having a wedge-shaped cross section is inserted.
By pushing in the pressing strip 9 at 0, the peripheral bent edges 2a, 3a are pushed in by the pressing strip 9 and fixed in the first groove 7. Further, a protective protruding strip 11 of the anti-slip sheet 6 is similarly pushed into the second groove 8 on the upper surface side by a pressure roll 10 and fixed thereto.

In this case, the pressing strip 9 and the anti-slip sheet holding protruding strip 11 are formed of, for example, aluminum or synthetic resin shapes.

7 and 8 show a second embodiment of the sandwich panel of this invention, in which only the first grooves 7, 7 are provided symmetrically on the upper and lower surfaces of the peripheral frame 4. In this case, a pressing strip 9' that pushes the peripheral bent edge 2a of the surface plate 2 inserted into the groove 7 on the upper side
has a protrusion 1 for protecting the anti-slip sheet on its outer upper part.
1' are integrally provided in a protruding manner so that the surface plate 2 can be fastened and the anti-slip sheet 6 can be held at the same time.

Note that a pressing strip 9 is pushed into the groove 7 on the lower surface side, which serves only to fix the peripheral bent edge 3a of the lower surface plate 3, as in the first embodiment.

In the second embodiment configured as described above, the other structures are the same as those in the first embodiment, so the explanation thereof will be omitted.

As explained above, according to the sandwich panel of this invention, the peripheral frame only needs to be cut at 45 degrees at both ends, and no other notching is required, so it is easy to process. , safety in use can be ensured. In addition, unlike the conventional peripheral frame of this type of panel, the protrusions for protecting the anti-stick sheet are not integrally provided, so there is no need for plywood when filling the core material with foam, and furthermore, when fixing the top plate, one step is required. Since only the roll processing is required, the number of processing steps and processing time can be significantly reduced, and productivity can be improved. Moreover, since the peripheral frame is vertically symmetrical, excellent effects such as the ability to arbitrarily select the surface on which the anti-slip sheet is provided can be obtained by selecting the pressing strips and the like. Furthermore, since there is no notch in the anti-slip sheet protection protrusion, there is no chance of the anti-slip sheet turning over during use or causing injury due to the notch, so its utility value is significant.
