A flat rectangular reinforcing piece 35 attached to the lower surface of the flange portion 23.
Are lined up.

Next, a method of manufacturing (assembling) the clothes drying base constructed as described above will be described.

First, as shown in FIG. 4, green concrete 36 is poured into the empty room 1 for filling the fresh concrete of the base body 2. In this case, the injection amount is such that the ready-mixed concrete 36 fills the ready-mixed concrete filling vacant chamber 1 and does not overflow from the gap S when the cap 4 is fitted.

Then, after pouring the fresh concrete 36,
The cap 4 is fitted from above into the ready-mixed concrete filling empty chamber 1 through the fitting window portion 19.

At this time, the regulating projections 31 ... Of the cap 4 are pushed in until they come into contact with the upper wall 8 of the base body 2 (that is, the upper horizontal wall portion 16), and the upper end portions 32c of the respective tapered ribs 32 are pushed.
Is pressed against the inner peripheral edge 33 of the fitting window portion 19.

However, in the state where the cap is fitted, as shown in FIG.
As shown in FIG. 2 and the air bleeding gap S is formed, when the cap 4 is fitted, the air in the ready-mixed concrete filling chamber 1 is discharged to the outside, and the cap 4 can be fitted easily. You can

Further, after the fitting, the tapered rib 32 is in pressure contact with the inner peripheral edge 33 of the fitting window portion 19, so that the cap 4 does not float up due to the buoyancy force from the fresh concrete 36.

When the raw concrete 36 inside is solidified and becomes the concrete body 5, the clothes base is completed, but when the clothes pillar 30 is not formed of a stainless pipe, the insertion holes 3a, 3b. As shown in FIG. 1, drainage holes 37, 37 are formed at the lower ends of the first and second cylinders 21, 22 so that water will not be collected in the first and second cylinders 21, 22.

That is, after the fresh concrete 36 is solidified to form the concrete body 5, it is perforated by a perforating tool such as a drill to form the water draining holes 37, 37.

Therefore, if the clothes prop 30 is formed of a stainless pipe, the drain hole 37 is not necessary and can be omitted.

Further, in the embodiment, the first and second cylindrical bodies 21, 22 are
Since the dimension F between the lower end of the base and the bottom wall 6 of the base body 2 is set small, for example, 10 mm or less,
The water drain hole 37 can be easily drilled.

When a base is manufactured, a large number of bases are manufactured. Therefore, as shown in FIG. 1 and FIG.
Are stacked on one base, and in this state, as shown in FIG. 4, fresh concrete 36 is poured into the empty room 1 for filling fresh concrete,
By fitting the cap 4 into this, another base can be formed on one base.

When another base is stacked on the lower base, the bottom wall 6 of the upper base 2 is placed on the lower horizontal wall portion 14 of the upper wall 8 of the lower base 2. However, by setting the depth dimension D of the concave portion 9 larger than the height dimension H of the upper wall 8,
A gap G is formed between the upper surface of the cap 4 of the lower base and the bottom wall 6 of the base body 2 of the upper base.

That is, the lower base is the upper wall 8 of the base body 2.
Will support the upper base at the lower horizontal wall 14 of
It can support the upper base sufficiently and can be stacked in 5 to 7 stages.

Therefore, it is possible to manufacture the bases in a stack in order while maintaining the normal posture in the upward direction without turning the formed bases upside down. That is, the weight of one base is about 17 to 28 kg, and there is no work of lifting it upside down and forming it upside down every time it is formed, resulting in excellent workability.

The bases stacked in a plurality of stages may be arranged side by side as shown in FIG. 5, but even in such a case, the bases can be easily lifted.

That is, the left and right side walls 7c, 7d of the base body 2
Recesses 13 and 13 are formed in each of the bases, and a gap is formed between the bases adjacent to each other. A hand is inserted into the gap, and the bottom wall 6 of the base body 2 (specifically, The hand can be hooked between the front and rear legs 10 and 10 and can be easily lifted.

Therefore, the manufactured bases can be stacked in a plurality of stages, and the bases stacked in a plurality of stages can be arranged in a plurality of rows in the horizontal direction and the vertical direction, so that a product mounting space can be placed. The product can be stored compactly without the need to take large.

Therefore, the base constructed as described above is
It is used as shown in FIGS. 7 and 8.

That is, for clothes drying, as shown in FIG.
The case where the book clothes columns 30 and 30 are closely arranged, and FIG.
As shown in FIG. 2, there may be a case where the two drying columns 30, 30 are arranged at a predetermined interval via the connecting body 39.

Therefore, as shown in FIG. 7, when the two drying columns 30, 30 are closely arranged, the two insertion portions 29,
When the two clothes columns 30 are inserted into the other insertion hole 3b having 29 and the two clothes columns 30, 30 are arranged at a predetermined interval, as shown in FIG. 30 is inserted, the other clothes pole 30 is inserted into the other insertion hole 3b,
A variety of clothes can be formed on one base.

Since the insertion holes 3a and 3b are provided in the cap 4 which is a single plastic molding,
The dimensional accuracy of the space between the insertion holes 3a and 3b is high, and the support column 30 can be reliably inserted into the insertion holes 3a and 3b.

The present invention is not limited to the above-mentioned embodiment, and the design can be freely changed without departing from the gist of the present invention. For example, the insertion hole for inserting the clothes pole 30 is of course 1 The number of the tapered ribs 32 may be freely increased or decreased, and the upper end 32c of the tapered ribs 32 in the cap fitted state has an inner peripheral edge 33 of the fitting window 19 even when the cap is fitted. It can be freely changed as long as it is pressed against.

Further, the restricting protrusion 31 for forming the air bleeding gap S may be provided on the upper surface of the upper wall 8 of the base body 2 instead of being provided on the lower surface of the flange portion 23. Even if the thickness of the restriction protrusion 31 is
It can be freely changed as long as the air bleeding gap S is formed between the base body 2 and the upper wall 8 of the base body 2.

[0057]

Since the present invention is constructed as described above, it has the following effects.

In the case of manufacturing, the fresh concrete 36 is poured into the empty room 1 for filling the fresh concrete of the base body 2 through the fitting window portion 19, and then the cap 4 is moved upward through the fitting window portion 19. Since it only has to be fitted into the vacant chamber 1, the manufacturing work thereof is extremely simple.

In addition, the air in the vacant chamber 1 is evacuated from the air bleeding gap S formed between the flange portion 23 and the upper wall 8 of the base body 2 without separately providing an air bleeding hole in the base body 2. It is possible to reliably push out the fresh concrete 36 into the vacant chamber 1 and the base body 2 has a simple overall shape, the base body 2 is easy to manufacture, and the base body is excellent in design. Will be

Further, in the cap fitted state, the upper end portion 32c of the tapered rib 32 is pressed against the inner peripheral edge 33 of the fitting window portion 19 so that the cap 4 does not float up and protrude from the base body 2. The work of pressing the cap 4 in order to prevent the floating is unnecessary, and the manufacturing is easy.

Further, the air bleeding gap S acts as a drying gap when the cap is fitted, and has the advantage of accelerating the solidification of the ready-mixed concrete 36 in the ready-mixed concrete filling chamber 1.
