[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage device for a balcony that receives rainwater that has fallen on the upper surface of a balcony deck protruding from a building frame with rain gutters provided on a beam and a front girder, and drains the rainwater to the ground via a rainwater guiding member.
[0002]
[Prior art]
There are two types of balconies that protrude from the building body: a columnar type that supports the corner of the balcony by a column standing on the ground and a column type that does not have such a column. In either case, a drainage device is provided to guide and drain rainwater that has fallen on the deck from the bottom surface of the deck without being dropped.
[0003]
The drainage device on the balcony has a rain gutter (rear kite) provided with rainwater flowing out from the rear end (end of the driver side) on the top surface of the deck, or a rain gutter (rear kite) provided on the rear end portion of the top surface of the deck. ), Then let it flow down to the rain gutter (side gutter) provided on the Tsumara, receive rainwater flowing out from the side edge on the top surface of the deck (side edge of the Tsumago) with the side gutter, Rainwater flowing out from the front girder side edge) is received by a rain gutter (front gutter) provided at the front edge of the top surface of the deck, joined from the front gutter to the side gutter, One that drains to the ground via a rainwater guide member such as a vertical shaft or a water guide chain (see Patent Document 1), a collecting rod is provided at a position one level lower than the side rod of the fuselage, and further collects rainwater collected on both sides There is known one that collects in a collecting rod and drains it to the ground via a rainwater guiding member (see Patent Document 2). Also, all the rainwater that has flowed down from the deck side end to the side gutter is gathered on the front gutter provided in the front girder and drained from the front gutter to the ground via the rainwater guiding member (Patent Document 3) Is also known.

In particular, the columnar type balcony can be installed with the top of the deck, and therefore the twill beam, tilted so that the front girder side is slightly higher than the joisting side (this is hereinafter referred to as “upward”). is there. The reason is that the front spar side is somewhat lowered due to aging or deterioration, and is designed to be horizontal when it is lowered in anticipation of it. If it is installed horizontally from the beginning, the rain gutter of the girder will incline so that the front girder side is lower than the joisting side due to secular change or deterioration (this is hereinafter referred to as the first descent).
[0006]
[Problems to be solved by the invention]
However, conventionally, the girder rain gutter, the front girder gutter, and the joist hanging gutter are all integrally formed with the girder, front girder, and joist hanger. Therefore, in the balcony that is set up first, (a) most of the rain that falls on the top surface of the deck will be concentrated in the joist hanging gutter, but the joist hanging gutter is usually thin. There is a problem that rainwater overflows and drops below the deck. In addition, (b) when a standing ledge is coupled near the outdoor side end of the tsum girder, rainwater accumulates in the gutter of the tsum girder and is not completely drained early after the rain ends. Therefore, if the watertightness of the end of the rain gutter of the Tsumara is not good, water leakage is likely to occur from the end of the end of the tsum girdle. When the deck becomes horizontal due to secular change or the like, the drainage performance of the gutters on the top surface of the deck and the girder decreases.
In addition, when the deck where the vertical frame is connected to the end of the end of the Tsumago is installed horizontally, the Tsubame's gutter after the Tsubame's rain gutter has fallen down due to secular change or deterioration. There is a problem that rainwater accumulates in the front girder side of the rain gutter, the drainage performance is similarly reduced, and water leaks or drops from the front girder side end of the girder.
[0007]
The present invention has been made in view of the above circumstances, and the problem is that the deck material can be easily mounted at an accurate position, and the leakage and dripping of the girder from the rain gutter is effectively prevented. Is to provide a deck drainage device.
[0008]
[Means for Solving the Problems]
To solve the above problems, the present onset Ming, a side edge portion of the deck gutter which is provided on the deck inner surface wife beam from the side end portion of the deck upper surface to face (hereinafter, referred to. Tsumaametoi) rainwater flowing to flow into the wife gutter, the deck upper surface before gutter to the digit-side end portion is provided on the deck inner surface of the front spar to face (hereinafter, referred to as pre gutters.) to the deck The rainwater flowing out from the front end of the front rain gutter is caused to flow into the front rain gutter, and the rain water that has flowed into the front rain gutter is joined to the tsum gutter from the notch or hole formed in the longitudinal end of the front rain gutter, In a drainage device for a balcony that drains to the ground via a rainwater guiding member that is connected to the vicinity of the front girder side end of the Tsumage Gutter , one plate material is inserted into the gutter gutter in the gutter gutter. In a state of sealing at the hanging end surface and projecting upward from the upper opening surface of the groove A small Kuchifusagi and decking mounting a starter of the wife gutter by fixing the Tsumaametoi, a plate of the plate material and the same shape and dimensions, as well as sealing the front spar side end face of the wife gutter, It is characterized in that the small gutter of the wife rain gutter is closed by being fixed to the wife rain gutter without protruding upward from the opening surface of the groove of the wife rain gutter .
[0009]
With this configuration, rain water flowing out of the frontage direction end portions of the deck upper surface flows into the wife gutter, after rainwater flowing out of the front end of the deck upper surface that has flowed into the front gutter, his wife gutter through the cutout It joins and is drained to the ground via a rainwater guiding member.
The starter for closing and closing the deck material closes the end face on the side of the gutter gutter groove, preventing the rainwater that flows into the gutter gutter from flowing out to the side joist side. It is possible to easily and accurately determine the start position of the joist hanging side when placing the material on the joist, and therefore, it is possible to prevent rainwater flowing out from the side end portion of the deck upper surface from dripping from the position where it is removed from the wife gutter. . Further, the same plate material can be simply and accurately attached at both ends of the Tsumage Girder, so that the closing of the groove end and the positioning of the deck material on the housing side can be performed easily and accurately.

[0020]
As shown in FIGS. 10, 12, 13, and 14, the Tsumage Girder 12 includes an outer vertical wall 12 a, a bottom wall 12 b that extends horizontally inward from a lower end portion of the outer vertical wall, and a bottom wall 12 b The inner end portion has an inner vertical wall 12c extending in the vertical direction, and the outer vertical wall 12a stands up to a position higher than the inner vertical wall 12c. And the groove | channel 12d opened upward by the upper part rather than the bottom wall of the outer vertical wall 12a, the bottom wall 12b, and the inner vertical wall 12c, and opening in the longitudinal direction of the gutter is formed. Further, support edges 10e; 10f, 12g extending horizontally inward are provided at the upper end of the outer vertical wall 12a and the upper and lower ends of the inner vertical wall 12c. Screw holes 12h and 12i are provided in the outer vertical wall 12a and the inner vertical wall 12c forming the groove 12d.
[0021]
As one method for facilitating the mounting of the wife gutter 12 in a lowered state, the height from the upper surface of the auxiliary gutter 3e of the girder 3 to the upper surface of the joist support 5d of the joist 5 is 3 is designed to be larger than the height from the upper surface of the auxiliary rain gutter 3e to the upper surface of the joist support 7d of the front girder 7.
Then, a gutter gutter 12 is spanned between the joist hung 5d and the front girder 7 after being connected in a rectangular frame shape, the outer vertical wall 12a of the gutter gutter is in contact with the inner wall 3b of the girder 3, and The lower supporting edge 12g of the inner vertical wall 12c at both ends in the longitudinal direction of the wife rain gutter 12 is placed on the joist support 5d of the joist hook 5 and the joist support 7d of the front girder 7, and the joist support 5d thereof. , 7d, both ends of the wife rain gutter are fixed by screws s5 screwed into these from below. Therefore, the wife gutter 12 is attached in a downward-falling state.
[0022]
In this case, as shown in FIG. 10, at the both ends in the longitudinal direction of the twilight gutter 12, two twilight gutters 13a, 13b having the same shape and size are screwed by screws s6 screwed into the screw holes 12h, 12i. Installed. The wife rain gutter blockages 13a and 13b are formed of a rectangular plate 13, and the height thereof is slightly larger than the depth of the groove 12d, that is, the distance from the bottom wall 12b to the support edge 10f.
As shown in FIG. 10 and FIG. 12, the lower end of the wife rain gutter 13a attached to the end of the rain gutter 12 is attached with its lower side coincident with the bottom wall 12b. The end in the longitudinal direction of the groove 12d is sealed, and the upper end portion of the wife rain gutter blockade 13a projects upward from the support edge 10f. Further, as shown in FIG. 10 and FIG. 13, the top of the wife rain gutter closing block 13b attached to the front end portion of the wife rain gutter 12 is attached with its upper side coincident with the support edge 10f. The longitudinal end is sealed.
[0023]
When the twill gutter 12 abuts against the inner surface of the twill beam 3 and is spanned between the joist 5 and the front girder 7 and fixed at the supporting edge 12g by the screw s5, the supporting edge 12f is attached to the deck material. It is used to place and support the side end portions (end portions in the frontage direction) of 14 decks.
[0024]
Next, at the intermediate position in the longitudinal direction of the joist hook 5 and the front beam 7, a plurality of known joists 13 that are long in the direction perpendicular to the joist hook 5 and the front beam 7 are parallel to the beam 3 at a predetermined interval. It is stretched and fixed. The joist 13 has a height equal to the height of the inner vertical wall 12c of the wife gutter 12, and both longitudinal ends thereof are respectively mounted on the joist support 5d of the joist hook 5 and the joist support 7d of the front girder 7, and screws s5 and It is fixed with the same screw. Therefore, the upper surface of the support edge 12f of the wife rain gutter 12 and the upper surface of each joist 13 are all on one common front-facing inclined surface.
[0025]
Then, the known deck members 14 are sequentially attached on the common inclined surface in the direction from the housing side to the front beam side as follows. That is, the first deck material is placed on the joist 13 and the support edge 12f of the Tsumago 12 and slides in the direction of the frame 1. At this time, as shown in FIG. 11, the end of the end of the rain gutter 12 is provided with a wife rain gutter closing block 13a that protrudes upward from the support edge 12f. It is stopped by the rain gutter blockade 13a. In other words, the Tsumago-gama fortress 13a functions as a starter for installing the deck material, and by simply sliding the first deck material in the frame direction, the deck material is accurately positioned, and the other deck materials following the joist 13 are sequentially placed. Simply place it on the support edge 12f of the Tsumage Gutter 12 and slide it in the direction of the frame 1 to easily and quickly position all deck materials at the specified positions as designed and insert them between each deck material. The deck material 14 can be smoothly fixed by screwing the screw s6 to be screwed into a screw hole that is previously opened in the joist 13.
[0026]
And the frame side edge part of the first deck material is coat | covered with the cover part 5b of the joist hook 5 (refer FIG. 11). Further, the deck side end of each deck material 14 is placed on the support edge 12f as described above, and faces the groove 12d of the tsumage rain gutter 12. The side edge of the deck material and the groove 12d are The deck cover 15 is covered with a decorative screw s7 on a support edge 12e formed on the upper end of the outer vertical wall 12a of the wife rain gutter 12 (see FIGS. 12 and 13). Further, the end of the last deck member on the outdoor side faces the front gutter 7c of the front girder 7.
[0027]
[ Configuration of drainage equipment ]
The balcony is provided with a drainage device as described below. That is, the side end of the top surface of the deck faces the groove 12d of the Tsumage Gutter 12, and the end of the frame side and the end of the outdoor side of the Tsumage Gutter groove 12d are hermetically sealed by the Tsumage Gutter fortifications 13a and 13b. Yes. In the vicinity of the outdoor side end of the gutter 12, a rain water dropping hole 12 j is provided at the bottom of the groove 12 d, and the upper end of the rain water dropping cylinder 16 is coupled to the hole. Accordingly, the rainwater flowing out from the side end portion of the deck flows in the tipping rain gutter 12 toward the outdoor end portion, and then flows down from the rainwater falling hole 12j to the rainwater dropping tube 16.
On the other hand, the outdoor side end of the top surface of the deck faces the front gutter 7c of the front girder 7 (see FIG. 11), and as shown in FIGS. 7 and 9, at least one end in the longitudinal direction of the front gutter 7c. Is cut out over a length not exceeding the width of the groove 12d of the rain gutter to form a rainwater dropping hole 7e. And since the bottom of the rain gutter 7c exists in a position slightly higher than the support edge 12f of the wife rain gutter (see FIG. 11 and FIG. 13), the rain water flowing into the rain gutter 7c from the top of the deck passes through the hole 7e. It flows down into the groove 12d of the Tsumago 12 and merges with the rainwater that flows in from the side end of the deck, and then flows down from the rainwater fall hole 12j to the rainwater fall tube 16.
[0028]
As illustrated in FIG. 11, the rainwater that has fallen on the rainwater dropping cylinder 16 flows down in the vicinity of the chassis through an elbow 17 a, a call 18, another elbow 17 b, and a vertical rod 19, and is drained to the ground. Is done.
[0029]
Since FIG. 11 illustrates the case of a columnar type balcony, in order to drain the rainwater dropping cylinder 16 provided near the front girder 7 to the ground, the rainwater falling cylinder 16 is connected to the elbow 17a, the call 18 and Although it is desirable to connect to the vertical frame 19 provided near the frame through the elbow 17b for the appearance and the prevention of the obstacle, even in the case of a columnar type balcony or a columnar type balcony In particular, the lower end portion of the rainwater dropping cylinder 16 may be coupled to a vertical pole provided vertically below or provided close to the pillar.
[0030]
Further, FIG. 11 exemplifies a case where the top surface of the deck is first lowered. However, even in the first-up deck, since the Tsumago is attached to the first descending, it goes without saying that good drainage can be obtained. Nor.
[0031]
As described above, the Tsumago 12 is formed separately from the Tsumago 3 so that the Tsumage Girder can be moved down to the Tsum Liang regardless of whether the balcony is uphill, horizontal, or downhill. Therefore, even if the installation angle of the balcony changes due to aging, etc., the rain that always falls on the top surface of the deck is allowed to flow toward the outdoor side end of the Tsumage Gutter, and the outdoor side end thereof It can be drained to the ground from the vicinity, and even when there is a lot of rainfall, it can be surely prevented from overflowing from the end of the frame side of the Tsumara.
[0032]
In the example shown in the drawing, the rainwater that has flowed into the pre-rain gutter 7c is once merged into the tsum gutter 12 and then caused to flow into the rain water drop cylinder 16. A drop cylinder may be coupled, and a common call or stand or a rain water guiding member such as a water guide chain may be coupled to the lower end of the rain water drop cylinder. In addition, when the deck material closest to the front girder 7 is provided with a gutter (front gutter) and flows in the direction of the gutter gutter instead of the front girder direction, the structure for allowing rainwater to flow into the gutter gutter from the front girder described above. Is no longer necessary.
[0033]
【The invention's effect】
According to the present invention, only attaching the members of the same shape and size at both ends of Tsumaametoi can be performed with small Kuchifusagi the ends of Tsumaametoi and a mounting deck member mounted starter. In addition, the deck material can be easily mounted at an accurate position, and water leakage and dripping from the rain gutter of the twill beam can be effectively prevented.
