It is arranged so as to penetrate the center of gravity of the outer surface of the second long side wall 12. Further, the plurality of groove portions 21B of the first engaging portion 21 are arranged so as to line up with the second direction H2 and the third direction H3 orthogonal to the second direction H2, and the plurality of groove portions 22B of the second engaging portion 22 are the first. They are arranged so as to line up with the direction H1 and the third direction H3.

As shown in FIG. 6, the above-mentioned stacking engaged portion 30 is arranged in the recess 15 of the base portion 10B as described above. Specifically, the stacking engaged portion 30 has a cylindrical inner fitting portion 31 protruding from the outer surface of the internal reinforcing wall 14 located in the recess 15, and a second direction from the inner fitting portion 31. It has a fitting rib 32 projecting from H2 and the third direction H3, and a cylindrical outer fitting portion 33 protruding from the outer surface of the internal reinforcing wall 14 in the first direction H1 at four corners in the recess 15. Further, as shown in FIG. 9, the end faces of the inner fitting portion 31 and the fitting rib 32 are flush with the opening surface of the recess 15, and the end face of the outer fitting portion 33 is on the back side of the opening surface of the recess 15. Is located in.

The panel auxiliary legs 10 can be connected to each other by engaging the stacking engaged portion 30 with the first and second engaging portions 21 and 22. Specifically, the inner fitting portion 31 of the stacking engaged portion 30 is fitted inside the cylindrical portions 21D and 22D of the first and second engaging portions 21 and 22, and the groove portions 21B and 22B are fitted. The fitting ribs 32 may be fitted so that the tips of the cylindrical portions 21D and 22D are brought into contact with the internal reinforcing wall 14. As a result, the panel auxiliary legs 10 are positioned with each other in the direction of the central axis in a state where the panel auxiliary legs 10 are centered and are also prevented from rotating. Further, by sandwiching the vertically split projecting pieces 21A and 22A constituting the cylindrical portions 21D and 22D between the inner fitting portion 31 and the outer fitting portion 33, buckling deformation thereof is prevented. Then, the panel auxiliary legs 10 are held in a connected state by friction locking of each fitting portion.

This concludes the description of the configuration of the panel auxiliary legs 10 of the present embodiment and the floor panel 50 to be used thereof. Next, the action and effect of the panel auxiliary leg 10 will be described.

The panel auxiliary legs 10 are shown in FIG. 7, a high independent mode of the panel auxiliary legs 10 having a high posture as shown in FIG. 4, a low independent mode of the panel auxiliary legs 10 having a low posture as shown in FIG. As shown in FIG. 8, a high composite mode in which the high-profile panel auxiliary legs 10 are connected on the high-profile panel auxiliary legs 10 and a high-position panel auxiliary legs 10 on the low-profile panel auxiliary legs 10 as shown in FIG. It can be used in four modes including a low composite mode in which the above-mentioned is connected, whereby it is possible to correspond to four types of floor panels 50 having different heights.

In order to attach the panel auxiliary legs 10 to the floor panel 50, the floor panel 50 is turned upside down, and the panel auxiliary legs 10 in a mode corresponding to the height of the floor panel 50 are also turned upside down. Then, the first or second engaging portions 21 and 22 of the panel auxiliary legs 10 are engaged with the second lower surface rib 53B at the portion where the floor panel 50 needs to be reinforced. Specifically, the second lower surface rib 53B may be pushed into the grooves 21B and 22B of the first or second engaging portions 21 and 22 to bring them into contact with the base portion 10B. As a result, the panel auxiliary legs 10 are positioned in the vertical direction with respect to the floor panel 50, the lower surface of the support legs 52 of the floor panel 50 and the lower surface of the panel auxiliary legs 10 are arranged flush with each other, and the second lower surface ribs. The panel auxiliary legs 10 are held in a state of being attached to the floor panel 50 by frictional locking between the 53B and the inner surfaces of the grooves 21B and 22B. Then, the top and bottom of the floor panel 50 may be returned to their original positions and placed at an arbitrary position on the foundation surface of the building. As a result, even if the floor panel 50 is cut during the construction work of the raised floor, the floor panel 50 can be easily reinforced. Even when the floor panel 50 is not cut, the panel auxiliary legs 10 may be used to reinforce the floor panel 50 when high load bearing capacity is required.

Further, the panel auxiliary leg 10 of the present embodiment is provided with a stacking engaged portion 30 on the opposite side of the first engaging portion 21, and the stacking engaged portion 30 is connected to another panel auxiliary leg 10. By engaging the first or second engaging portions 21 and 22, the panel auxiliary legs 10 are held in a stacked state, which is a second feature. As a result, the types of floor panels 50 that the panel auxiliary legs 10 can handle are expanded to four types. As described above, the panel auxiliary legs 10 of the present embodiment do not need to have the same types according to the floor panel 50 as in the conventional case, and one can support a plurality of types of floor panel 50. Costs, manufacturing costs, etc. can be suppressed. Further, since the panel auxiliary legs 10 of the present embodiment have a housing structure, the material cost can be suppressed and the weight can be reduced as compared with the case of the solid structure. Moreover, since the first and second engaging portions 21 and 22 have a simple structure in which the cylindrical walls 21D and 22D are vertically divided, they can be easily manufactured. Further, since the stacking engaged portion 30 is received in the recess 15, the stacking engaged portion 30 can be prevented from being deformed or damaged.

The panel auxiliary leg 10 of the present embodiment may have a configuration in which a third engaging portion is provided on one of the pair of first long side walls 13. At that time, by turning the third direction H3 in the vertical direction and making the height of the posture in which the third short side wall 13 is arranged on the upper side different from the heights of the low posture and the high posture described above, the panel auxiliary leg 10 alone Aspects are widened.

Further, the panel auxiliary leg 10 of the present embodiment has a configuration in which the engaging portion 30 for stacking has the outer fitting portion 32 and the fitting rib 33, but the outer fitting portion 32 and the fitting rib 33 The configuration may be such that either one or both are excluded.
