Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drainage system for the lower end of a support such as a handrail support installed at the upper end of a parapet on the roof floor of a building.

[Conventional technology]

Generally, supports such as handrails that are erected at the upper end of a parapet on a roof floor of a building are erected by attaching a support member to the upper end of the parapet and welding or screwing to this support member. In addition, the lower end of the pillar is hidden by a cap attached to the upper end of the parapet to prevent it from looking unsightly.

Furthermore, rainwater that has entered the inside of the support from the connection between the support and the upper chord (handrail) at the lower end of the support corrodes and damages the parapet upper end cap wood and support members of the support, or the parapet frame is damaged. Drainage holes are provided to quickly drain out rainwater to prevent it from adversely affecting the water.
As an example of this type, the one described in Japanese Utility Model Application Publication No. Sho 59-104923 is known.

[Problem that the invention seeks to solve]

However, according to the method described in the publication, the drainage hole is located above the cap tree at the upper end of the parapet and is exposed to the outside, so rainwater that has entered inside the support pillars cannot be drained away quickly during strong winds. Not only that, but there is also the risk that dust, sand, etc. may enter the pillar through the drainage hole, leading to a decrease in drainage function and corrosion of the pillar legs due to infiltrated rainwater.

Furthermore, since the mounting portions of the support members and the like at the lower ends of the columns are exposed to the outside, they are exposed to the wind and rain, and have the disadvantage that they are not only susceptible to rust but also look unsightly.

This invention was proposed in order to solve the above-mentioned conventional problems, and is capable of quickly draining rainwater that has entered the pillar, maintaining its function semi-permanently, and improving the appearance design. It is an object of the present invention to provide a drainage device for the lower end of a support such as a handrail support that is extremely excellent in terms of performance.

[Means to resolve the problem]

In this invention, a joint fitting 5 is attached to the upper end 2 of the parapet 1, and a support 7 such as a handrail support is connected to the mounting rod 10 of the joint fitting 5 at its lower end.
The parapet 1 is installed by inserting it into the upper end 2 of the parapet 1, and the drain fitting 6 is installed directly below the pillar 7, and a predetermined gap is provided between the lower end of the pillar 7 and the drain fitting 6. The above object is achieved by attaching the cap 17 so as to cover the drainage equipment 5 and the drainage equipment 6.

The water collection part 39 is formed into a rectangular plate shape with a diameter one size larger than the outer diameter of the handrail support 38, and a rising part 39a is formed continuously in the circumferential direction of the water collection part 39 on the peripheral edge thereof. There is.

In addition, a mounting rod 32 is installed approximately in the center of the water collection portion 39.
An opening 39b having approximately the same diameter as the outer diameter of is formed,
Further, mounting portions 39c, 3 are provided at the edge of the opening 39b.
9c is formed. The drainage section 40 is the water collection section 39
It protrudes diagonally downward from the corner. Rising portions 39 of the water collection portion 39 are provided on the left and right sides of the drainage portion 40.
Rising portions 40a, 40a that are continuous with a are formed continuously.

The drainage tool 37 formed in this way is connected to the opening 3
9b into the mounting rod 32 and drain section 40.
is installed on the column positioning bracket 31 in a state where it hangs down inside the rooftop parapet 1, and the mounting part 39
c, 39c are fixed to the mounting rod 32 by screwing them with the mounting screws 16, 16.

In such a case, the distal end of the drainage section 40 is overlapped with the opening 31a of the column positioning fitting 31 so that the entire structure is not bulky.

Furthermore, the gap between the opening 39b and the mounting rod 32 is completely sealed with a sealing material. The handrail post 38 is formed into a cylindrical shape with a rectangular cross section so that it can be inserted into the mounting rod 32.

Then, the handrail post 38 is made by fitting the back metal 41 into the mounting rod 32, and after attaching the corner cap 17, inserting the lower end of the handrail post 38 into the mounting rod 32, and attaching it to the lower end of the handrail post 38. Bolt holes 35, 35 and bolt insertion hole 3 of mounting rod 32
It is installed at the upper end of the roof parapet 1 by screwing a plurality of fixing bolts 26, 26 into the screw holes 41a, 41a of the back plate 41 from 4, 34. In addition, the back metal 41 inside the mounting rod 32 is
The handrail support 38 is fixed by the inner protrusions 32a, 32a.
The bolt hole 35 of the mounting rod 32, the bolt hole 34 of the mounting rod 32, and the screw hole 41a of the back metal 41 are supported in an overlapping state, so that the fixing bolt 26 can be easily tightened.

The other configurations are almost the same as the first embodiment.

In such a configuration, rainwater that has entered the handrail support column 38 is collected on the water collection section 39 and quickly drained to the rooftop via the drainage section 40.

FIGS. 10 and 11 show modified examples of the drain tool, and the drain tool 6 shown in FIG. The drainage device 6 shown in Fig. 11 has mounting parts 6d, 6d.
is provided to protrude directly below the edge of the opening 15.

FIG. 12 shows another installation mode, in which the joint fitting 42 is installed in a recessed manner. In the figure, number 45 is a recess provided at the upper end of the rooftop parapet 1, number 46 is an anchor fitting, and reinforcing steel 4 in the concrete of the rooftop parapet 1.
Welded to 7. Number 48 is mortar. The other configurations are almost the same as the first embodiment.

〔Effect of the invention〕

Since this invention consists of the above, it has the following effects.

Since the drainage equipment is installed directly under the pillars erected at the upper end of the parapet, rainwater that has entered the inside of the pillars can be quickly drained away without accumulating directly under the pillars for a long period of time. Therefore, it is possible to prevent corrosion of the capboard at the upper end of the parapet and the column support member of the upper joint fitting due to infiltrated rainwater, and the parapet frame is not adversely affected by infiltrated rainwater.

Since the joint fittings and drainage fittings are hidden by a cap, it is possible to prevent dirt, dust, sand, etc. from blowing in, and there is also a space between the bottom end of the support and the drainage fitting to quickly drain rainwater that has entered the support to the outside. Since a certain gap is provided to allow drainage to flow out, deterioration of drainage function can be prevented.

Furthermore, the appearance is also very good.
