Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drainage device at a unit intersection of a curtain wall, which collects and drains water at the intersection of units forming a curtain wall.

(Problems to be solved by the prior art and the invention) Between the curtain wall unit and the cubic unit, which are constructed by joining the curtain wall units in a vertical direction, for example, as in the case of Japanese Utility Model Sho 58-174514 It is possible to prevent rainwater from entering by, for example, placing a sealing material in close contact with the upright and arranging a water stop plate on the outside of the vertical chamber. Only the structure is secured, and there is no consideration for means for intruding beyond the water stop plate to the outside surface of the vertical room and discharging rainwater that falls along the vertical direction, so this structure increases as going to the lower layers. There is a problem that the possibility of inundation from the vertical is increased by the water that flows.

This invention was made with a focus on the problem of water blocking between this unit and the cubic, and is intended to newly propose a device having a high water infiltration prevention effect.

(Means for Solving the Problems) According to the present invention, by collecting and draining water at the intersection of four curtain wall units that gather on one side, the increase in water that propagates on the side is suppressed, and the unit on the side Improve the waterproofness between.

The drainage device is provided on the upper frame of the two adjacent curtain wall units on the lower side of the four curtain wall units, the drainage plate that closes the gap between the upper frames, and the outdoor side that is part of the upright. A drainage block, which is housed in a recess surrounded by both side walls and a connecting wall, and which has a water collecting plate that abuts against the connecting wall, is mounted, and a water collecting block having a gutter that fits in the water collecting plate is placed on the vertical connecting wall. The water falling from the upper layer is collected by the water collecting block at each intersection of the curtain wall units, and at the same time, is drained from the drain block to the outside of the curtain wall unit.

(Embodiment) The present invention will be described below with reference to the drawings illustrating an embodiment.

The drainage device D of this invention is a curtain wall constructed by attaching a preassembled curtain wall unit U to a vertical M fixed to the frame of a structure as shown in FIG. 1 to FIG. It is installed at the intersection of the four curtain wall units U gathering in the upright M, where rainwater that falls from the upper floors along the upright M is collected and drained.

As shown in FIG. 1, the drainage device D is a drainage block A that is placed on the upper frames f ₁ and f ₁ of the lower two curtain wall units U, U of the four curtain wall units U.
And side walls m1 and m1 that are a part of the cubic M and that face outside the room.
Fits in the recess surrounded by and the connecting wall m2 connecting it,
The water collecting block B is fixed to the connecting wall m2, and the water collecting block B penetrates into the concave portion of the upright M from between the curtain wall units U, U which are laterally adjacent to each other and travels there. The falling rainwater is collected and dropped to the drainage block A, and further, the water received from the water collection block B by the drainage block A is discharged to the outside of the curtain wall unit U.

As shown in FIG. 2 showing the state before the installation of the drainage block A, the water blocking plate 5 is laid in the height direction between the vertical frames f ₂ and f ₂ of the adjacent curtain wall units U, U, and A drainage space S for draining rainwater is provided between the water stop plate 5 and both vertical frames f ₂ , f _2.
Are formed.

Further, airtight materials 6 are attached to the indoor side of the upper frames f ₁ and f _{1 which} are in close contact with each other and the outdoor side end surface of the cubic M over their entire lengths.

Drain block A is a curtain wall unit consisting of these two
U, span the upper frame f _1, f ₁ of U, separate from the drainage plate 1 rests directly on Tatewaku f _2, f _2, integrated in Kataritsu M side to the drainage plate 1, or the drainage plate 1 The drainage plate 1 is formed of a body, rises and fits in the concave portion of the upright M, and abuts against the connecting wall m2 thereof. The drainage plate 1 is arranged on the upper side as shown in FIGS. a planar shape widening in the outdoor side of the frame f _1, the upper frame f ₁ is thereto
It is graded along.

In addition, a weir 1a is formed on the drain plate 1 over the entire circumference to prevent water from flowing out of the drain plate 1.

The water collecting block B is located on the water collecting plate 2 of the drainage block A, and the gutter 3 inserted into the water collecting plate 2 is continuous on the lower side.

The water collecting block B is attached to the cubic M in advance at the factory.

In the illustrated embodiment, in order to prevent the inflow of rainwater due to wind pressure and the reverse flow of water discharged from the water collecting plate 2 on the water discharging plate 1, a stopper that closes the passage to the water collecting plate 2 at the center of the water discharging plate 1. The water wall 4 is projected. As a result, the water received by the water collecting block B goes around the water blocking wall 4 as shown in FIG. 4, is dispersed, and is discharged outdoors.

FIG. 3 shows the installation situation of the upper curtain wall unit U at the intersection, and as shown in FIG. 5 and FIG. 5, the vertical frame f ₂ is below the vertical frame f ₂ of the curtain wall unit U. A water receiver 7 having a slope for dropping water that has entered the inside ₂ onto the drain plate 1 is attached in a watertight manner by a sealing material 8.

(Effects of the Invention) The present invention is as described above, and a drainage block is installed at the intersection of the curtain wall units so as to straddle the upper frames of the lower two units and block the upper frame, and the vertical connecting wall Since the water is guided by the water collecting block fixed to the unit and is discharged to the outside in units, the waterproofness at the intersection is secured and rainwater can be prevented from entering the indoor side of the curtain wall.

In addition, this device is composed of prefabricated parts and can be placed on site only because the sealing material can be installed in the factory, that is, only the dry sealing material can be used for sealing. Good and reliable quality can be obtained.
