DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
This is abbreviated as FRP). In particular, a waterproof leg is attached to the bottom surface of the waterproof pan body by detachably attaching a supporting leg body made of an FRP molded product and screwing a height adjusting bolt to the supporting leg body. In addition to reducing the overall bread weight and improving the durability, the degree of freedom of the level adjustment width with respect to the installation surface is increased.

[0002]

2. Description of the Related Art Conventionally, in this type of waterproof pan, as shown in FIG. 4, for example, when level adjustment is performed on an installation surface G of a waterproof pan main body a, it is fixed to the bottom surface of the waterproof pan main body a with a screw b. A hat-shaped or square pipe-shaped steel part c is used, and a height adjusting bolt e is screwed and held on a holding nut d welded to the inner bottom of the steel part c, and FIG. As shown, at the time of forming the waterproof pan main body a by the SMC molding method, a holding nut d is directly embedded integrally with the bottom surface of the waterproof pan main body a, and a height adjusting bolt e is screwed into the holding nut d to hold the same. There is one having a configuration formed by the above.

[0003]

However, in such a conventional structure, when the height adjusting bolt e is held by the steel component c on the bottom surface of the waterproof pan body a as shown in FIG. The attachment of the component c increases the overall weight of the waterproof pan a, and the steel component c itself is easily rusted, so that a decrease in durability is inevitable.

A height adjusting bolt e is screwed and held on a holding nut d directly and integrally embedded in the bottom surface of a waterproof pan main body a as shown in FIG. Since the screwing range of e is small, there is a problem that the degree of freedom of the level adjustment width is small, and if the holding portion of the holding nut d is damaged by an external force, it cannot be reused.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a waterproof pan supporting leg structure capable of reducing the overall weight and improving the durability and increasing the degree of freedom of the level adjustment width with respect to the installation surface. Is to do.

[0006]

In order to solve the above problems SUMMARY OF THE INVENTION This invention relates to support legs attached site of the waterproof pan bottom panel consisting of FRP, an inverted conical cylinder block Ri Do from FRP moldings
A leg body having a hat-shaped shape and reinforcing ribs formed on the outer peripheral side surface is detachably mounted, and a bolt insertion hole is formed through the support leg body to be held at the open end side of the bolt insertion hole. provided with a nut, it is characterized in that the height adjustment bolt screwed was held in the nut.

[0007]

According to the present invention, a bolt insertion hole is formed through a leg body made of an FRP molded product which is detachably attached to a leg attachment portion on the bottom surface of the waterproof pan body by adopting the above-described structure. provided with a retaining nut on the opening end side of the bolt insertion hole, the height adjustment bolt is screwed and held in this holding nut, the support legs body, opposite circle
Has a frustum-shaped hat-shape and maintains strength on the outer peripheral side
Of the supporting leg itself can be made lighter, reducing the overall weight of the waterproof pan and improving the durability, and the degree of freedom of the level adjustment width with respect to the installation surface Becomes larger.

Further, since the support leg body is detachable from the waterproof pan main body, the support leg body is replaced due to breakage, or another part such as a suspension stand which replaces the support body is attached to the support leg mounting portion. Can be easily performed and has excellent compatibility with other parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings shown in FIGS. 1 to 3. As shown in FIG. It is a waterproof pan body made of.

FIG. 2 shows a bottom surface 1a of the waterproof bread main body 1.
As shown in FIG. 3, the reinforcing ribs 2 are integrally formed in a protruding manner in a lattice shape, and mounting holes 3 are formed in respective support surfaces 2 a of the reinforcing ribs 2, which serve as crossing points of the supporting legs. At the opening end 3a side of the mounting hole 3, a mounting nut 4 is integrally embedded.

In the drawing, reference numeral 10 denotes a hat-shaped main body of an inverted conical cylinder made of an FRP molded product, and a mounting flange portion 11 is integrally formed on an upper peripheral edge 10a of the main body 10; At each corner 11a of the mounting flange portion 11, a mounting hole 12 into which a mounting bolt 5 described later is inserted is drilled corresponding to the mounting nut 4 embedded in each support surface 2a of the waterproof pan main body 1. Along with
A plurality of reinforcing ribs 13 are formed on the outer peripheral side of the waterproof pan 1 along the vertical direction to maintain sufficient strength to support the load of the waterproof pan 1.

Further, a lower end face 10b of the support leg body 10 is provided.
The bolt insertion hole 14 is formed to penetrate therethrough. A holding nut 15 is integrally embedded in an opening end 14 a of the bolt insertion hole 14, and a height adjusting bolt 16 is mounted on the holding nut 15. It is screwed and held.

That is, the supporting leg body 10 abuts the mounting flange portion 11 on the supporting leg mounting portion of the bottom surface 1a of the waterproof pan main body 1, and makes the mounting holes 12 cross the reinforcing ribs 2 of the waterproof pan main body 1. The mounting holes 3 are provided in the supporting surfaces 2a of the respective parts, and the mounting bolts 5 are screwed into the mounting nuts 4 provided in the mounting holes 3 so as to be removably fastened and fixed. In adjusting the level of the installation surface G of the waterproof pan main body 1, the height adjustment bolt 16 is rotated.

In the above embodiment, it is also possible to mount another part such as a suspension base in place of the support leg body 10 on the support leg mounting portion of the waterproof pan main body 1. In this case, the suspension base or the like is used. Then, a mounting member corresponding to the supporting leg mounting portion of the waterproof pan main body 1 is fixed, and a mounting bolt 5 is screwed into a mounting nut 4 provided at the supporting leg mounting portion of the waterproof pan main body 1.

[0015]

As described above, according to the present invention, F
The FR is attached to the leg attachment site on the bottom of the waterproof pan body made of RP.
It is made of a P-shaped product and has a hat-shaped shape of an inverted conical cylinder.
Removable mounting of the leg body with reinforcing ribs on the peripheral side
In addition, a bolt insertion hole is formed through the support leg body, and a holding nut is provided on the open end side of the bolt insertion hole,
Since the height adjusting bolt is screwed and held on the nut, the supporting leg body itself can be lightened, thereby reducing the weight of the waterproof pan as a whole and improving the durability. The degree of freedom of the level adjustment width with respect to the installation surface can be increased.

Further, since the main body of the supporting leg is detachable from the main body of the waterproof pan, the main body of the supporting leg can be replaced due to breakage, or another part such as a hanging stand replacing the main body of the supporting leg can be attached to the mounting portion of the supporting leg. Can be easily performed, and the compatibility with other parts is excellent.
