Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a drainage system for a floor protruding from an external wall such as a balcony or veranda in a prefabricated house.

BACKGROUND ART Balconies and verandas of prefabricated houses are constructed by attaching a floor frame that protrudes from the outer wall, and attaching decks, handrails, etc. to the floor frame.

Problems to be Solved by the Invention The conventional structure described above has the disadvantage that rainwater, etc. that has fallen on the deck falls downward from the front and side surfaces of the balcony. This invention was made with the aim of solving the above-mentioned conventional problems.

Means for Solving the Problems In order to achieve the above object, in this invention, a floor frame is attached to protrude outward from the outer wall of the building, and on the back side of the deck installed on the floor frame, the floor A drainage pan consisting of a bottom plate and side plates surrounding the upper three sides of the bottom plate is installed on both left and right ends of the frame in the direction of the building's exterior wall, respectively, with the side plates forming the left and right ends of the deck and the front and rear sides, It is characterized in that rainwater etc. on the deck is guided to this drainage pan, and the drainage outlet of the drainage pan is connected to a drainage channel such as a water pipe or a gutter.

Embodiment In Fig. 1, 1 and 1 are floor frames made up of horizontal beam members 2 and 2, and crosspieces 3 and 3 passed between these beam members 2 and 2, respectively. In the embodiment, a pair of floor frames 1, 1 are installed so as to be continuous in the lateral direction and protrude from the outer wall 4 in FIG. 5. 5 is a decorative plate that covers the left, right, and front sides of the floor frame 1. Reference numerals 6 and 6 designate a drainage pan of the present invention, and as shown in FIG. is concave part 1
1 is formed, and a drain port 12 is formed in this recessed portion 11. In addition, the floor frame 1
A horizontal plate 13 protruding forward is formed by bending on the side plate 8 located on the front side.

As shown in FIG. 1, the drainage pan 6 formed in this way is attached to the side plates 8, 9, and 1 on the floor plates 1 at the left and right ends of the floor plates 1, 1.
10 are installed so that they are at the left and right ends of the deck 17 and on both the front and rear sides. At this time, a drain hole plate 14 is inserted into the drain port 12 of the recess 11 from above, and a drain hose 15 is connected to the tip of the drain hole plate 14 that protrudes downward from the bottom plate 7. Note that the connecting fittings between the drain hose 15 and the drain plate 14 are omitted.

Each of the drain hoses 15, 15 attached to each of the above-mentioned drain pans 6, 6 is attached to a 1
These drain hoses 15, 15 are inserted into the square gutters 16, and rainwater accumulated in these drainage pans 6, 6 is made to flow into the square gutters 16 from the respective drainage hoses 15, 15.

Reference numeral 17 shown in FIG.
At this time, both ends of the deck 17 are cut out at portions corresponding to the positions of the drainage eye plates 14, 14.

4 and 5 show how the deck 17 is installed, and 19 is a back guard attached to the rear side of the deck 17 to prevent rainwater on the deck 17 from falling below the rear of the deck 17. This back guard 19 protects the device.
On the other hand, a front guard 20 is also attached to the front side of the deck 17 to prevent rainwater on the deck 17 from falling to the front side. Therefore, the rainwater on the deck 17 flows only to the left and right ends, and flows from the drain pan 6 to the drain hose 15,
15 and into the square gutter 16. That is, all the rainwater on the deck 17 is drained from these drain hoses 15,
15, and will not fall from the left and right sides or the front of the deck 17. In addition,
Reference numeral 21 in FIG. 4 is a side panel that is attached to protrude upward from both left and right ends of the deck 17.

Effects of the Invention As described above, according to the present invention, all the rainwater on the deck is collected in the drainage pan, and is further discharged from this drainage pan through a drainage channel such as a hose or a gutter. There is no inconvenience of the product falling from the front or side. In addition, such drainage pans only need to be produced in advance at a factory and attached to the floor frame on site, which reduces the cost of on-site construction and is ideal for use as balconies or verandas in prefabricated houses. Moreover, the drain pan is supported by the deck on the back side of the deck, and the side plates of the drain pan are at the ends in the left and right direction and on both front and rear sides, so that the side plates can be held down by the deck. Since it can be supported so that it does not move at the end, it can be simply placed on the floor frame and no special installation work is required, making the work extremely easy. In addition, since they are installed on both the left and right sides of the deck, in other words, water is drained at two locations on both ends of the deck, the drainage performance is also improved.
