Abstract

(57) [Summary] [Purpose] We made it possible to increase the strength at a low material cost. [Structure] A mounting top portion 2, a pair of leg plate portions 3 projecting downward from both ends of the mounting top portion 2, and a pair of installation portions 4 bent outward in the horizontal direction from the lower end of each leg plate portion 3 are integrally provided. In the support leg for a floor base material including the support leg body 1, a pair of ribs 9 bent at right angles to the width direction are provided at both ends of the support leg body 1 in the width direction, and the mounting top 2 and the pair of ribs 9 are bent. It is provided continuously over the leg plate portion 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a supporting leg for a floor material used in a gymnasium and other buildings.

[0002]

[Prior art]

 As shown in FIGS. 6 to 8, the conventional support foot for flooring material has a mounting top portion 41, a pair of leg plate portions 42 projecting downward from both ends of the mounting top portion 41, and each leg plate portion 42. It is equipped with a support leg main body 44 that integrates a pair of installation parts 43 that are bent outward in the horizontal direction from the lower end of the, and mounts and fixes the pair of installation parts 43 on the foundation material of the building and There is one in which a supporting bolt is connected to the mounting top portion 41 through the mounting hole 46 so as to be vertically adjustable.

[0003]

[Problems to be solved by the device]

 However, although the conventional support leg body 44 is made of hot-rolled mild steel plate, etc., its strength is not sufficient and it is necessary to increase the thickness of the support leg body 44 to increase the strength. However, there was a problem that the material cost increased. In view of the above problems, the present consideration is aimed at improving the strength with a low material cost.

[0004]

[Means for Solving the Problems]

 The technical means of this consideration for solving this technical problem are the mounting top part 2, a pair of leg plate parts 3 projecting downward from both ends of the mounting top part 2, and the horizontal outside from the lower end of each leg plate part 3. In a support leg for an underfloor ground material including a support leg body 1 that integrally includes a pair of installation portions 4 that are bent in one direction, fold the support leg body 1 at both ends in the width direction at right angles to the width direction. A pair of curved ribs 9 are provided continuously over the mounting top 2 and the pair of leg plate portions 3.

[0005]

[Operation] When the support leg for floor material is used, the support leg body 1 bears a considerable amount of weight from the floor 13, but since the support leg body 1 has a pair of ribs 9, The strength of the support leg body 1 can be effectively increased, and even if the support leg body 1 is formed to have a thin plate thickness, the support leg body 1 can sufficiently withstand the weight from the floor 13.

[0006]

【Example】

 The present invention will now be described with reference to the illustrated embodiments. In FIGS. 1 to 4, reference numeral 1 denotes a support leg body, which is made of a galvanized hot rolled mild steel plate or a hot dip galvanized steel plate. And a pair of leg plates 3 projecting downward in a V shape from both ends of the attachment top 2, and a pair of installation parts 4 bent outward in the horizontal direction from the lower ends of the leg plates 3. A circular mounting hole 5 is provided in the center of the mounting top 2, a small-diameter mounting hole 6 is provided in the center of the pair of installation parts 4, and a rubber plate 7 for cushion is provided on the lower surface side of each installation part 4. Is installed. At the center of the pair of leg plate portions 3 in the width direction, a concave portion 8 curved outward is provided over substantially the entire length. A pair of ribs 9 are provided on both ends of the support leg body 1 in the width direction. The ribs 9 are bent outward at right angles with respect to the width direction of the support leg body 1, and the ribs 9 are continuously provided over the mounting top portion 2 and the pair of leg plate portions 3.

When using the support legs, for example, as shown in FIG. 5, a pair of installation portions 4 of the support leg main body 1 are placed on the foundation material 11 of the building, and the mounting holes 6 are used. Secure to the base material 11 with concrete nails 12. Insert the lower end of the bolt 14 that supports the floor 13 of the building into the mounting hole 5 of the mounting top 2, and clamp the mounting top 2 with a pair of nuts 15 and 16 screwed onto the bolt 14. The bolt 14 is connected to the top 2 of the mounting so that it can be adjusted vertically. The bolt 14 supports the floor 13 via the cushion 17, the bolt 18, the Daihiki steel 19 and the joist 20.

[0008]

[Effect of device]

 According to the present invention, a pair of ribs 9 bent at right angles to the width direction are provided at both ends in the width direction of the support leg body 1 continuously over the mounting top portion 2 and the pair of leg plate portions 3. Therefore, the ribs 9 can effectively increase the strength of the support leg body 1, and it is not necessary to increase the plate thickness of the support leg body 1 to increase the strength, and the material cost is accordingly increased. It can be offered at a low price because it does not happen.
