BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash upper frame structure capable of discharging water leaking from the upper surface of an upper frame of a sash to the outside of a room.

[0002]

2. Description of the Related Art At the time of window frame installation work, a sash is fitted so as to have a gap in a window frame mounting opening 31 which is somewhat large in a building frame 30 as shown in FIG. Is fixed in the gap (A or B) between the window frame 2 and the opening 31.
The window frame 2 is fixed to the frame 30 by welding a support rod 32 adjusted according to the size of the window frame 2 to the mounting plate 33a of the window frame 2 and the mounting auxiliary member 34 of the frame 30. The sash 1 prevents rainwater from penetrating into the room by the rising pieces 18A, which are provided on the upper surface of the upper frame 3 of the window frame 2 from the outdoor end, and the inclined pieces 16A, the outer wall 35 and the rising wall. primary coking S ₁ and the secondary coking S ₂ for even a single 18A and the frame 30 to prevent the infiltration of rain water is subjected,
The upper surface of the upper frame 3 during the coking is filled with mortar. In addition, the outer and inner sashes 6 and 7 are provided with a well-known drawing device, a closing member, and the like that allow the sashes to be drawn into close contact with each other and the window frame by operating the drawing handle. The inside and outside of the room are air-tightly partitioned so that there is no water leakage between the sash and between the sash and the window frame into the room.

[0003]

Generally, the dimensional accuracy of an opening hole made by concrete casting is not so high, and a gap A between the opening hole and the window frame is 30 mm to 60 mm as shown by an imaginary line. A large gap B was formed such that the secondary caulking between the skeleton and the rising piece was impossible. In the upper frame without such secondary caulking, if the adhesion of the primary caulk between the outer wall and the inclined piece is deteriorated and the seal breaks, the rainwater flowing down from the outer wall and the upper surface of the inclined piece are sprayed. The rainwater penetrates into the room from the slight gap that has been cut off by the pressure difference between the room and the outside, passes through the inclined piece, passes through the gap with the mortar, and eventually exceeds the rising piece without secondary coking. There was a problem of leaking water indoors. It is an object of the present invention to provide an upper frame structure of a sash that does not leak rainwater from a gap between an upper frame and an outer wall into a room when a secondary caulking cannot be performed due to a large opening hole for mounting a window frame.

[0004]

According to the present invention, in order to solve the above-mentioned problems, the present invention is applied to a base wall of an upper frame on which a sliding door guide piece is vertically provided so that an upward slope is formed from an outdoor end to a room side. In addition to providing the inclined piece over the entire length of the upper frame, a rising piece whose upper end is higher than the inclined piece is set up from the upper surface of the base wall above the middle part in the indoor / outdoor direction. In the upper frame of the sash that is caulked, a drainage channel is formed between the inclined piece and the front side of the rising piece without connecting them, and the base wall is placed outdoors facing the upper part of the sash. It is characterized by having a drain hole that leads to it.

[0005]

In the upper frame structure of the sash having the above structure, when rainwater penetrating from the gap of the caulk travels up the inclined piece and tries to enter the indoor side, the rainwater eventually reaches the indoor side end of the inclined piece, and the drainage channel is formed. The water is drained out of the room through a drain hole that is formed to communicate only with the outside of the room through the base wall above the outer sash by its own weight via the own weight, and is prevented from entering the room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a sliding window sash having an upper frame structure of the present invention as viewed from the outdoor side. As is well known, the window frame 2 of the sash 1 has an upper frame 3 and a rigid frame 4 and a lower frame 5 on the left and right sides thereof. As shown in FIG. 2, inside the window frame 2, an outer sash 6 on the outside and an inner sash 7 on the inside of the window are provided on the inner side of the upper frame 3. Each is fitted to open and close freely. An indoor wall 13 that covers the upper part of the indoor side surface of the inner shroud 7 extends downward from the indoor end of the base wall 10, and a guide piece bent at a right angle in the outdoor direction is provided at an upper end of the indoor wall 13 extending upward. 13a is provided. Between the guide piece 13a and the guide piece 13b on the opposite side, a sliding contact member 33 having a mounting plate 33a provided upright is provided movably along the guide pieces 13a, 13b.

At the outdoor end of the base wall 10, an outdoor wall 14 that covers the upper part of the outdoor surface of the outer sash 6 is vertically extended, and from the outdoor end 15 at the upper end, it is inclined upward toward the indoor. The inclined piece 16 is provided over the entire length of the upper frame 3. The indoor side end 16a of the inclined piece 16 is not connected to a later-described rising piece which is provided upright from the upper surface of the base wall 10, and a space drainage channel 19 is formed there. The drainage channel 19 is provided between the outer wall 14 and the outer wall 14 through a passage in a space surrounded by the base wall 10, the inclined piece 16 and the rising piece 18.
It communicates with the drainage hole 20 opened in 0. As shown in FIG. 3, three drain holes 20 are provided in the longitudinal direction in the longitudinal direction (in the case of the embodiment) so as to communicate only with the outside of the room. Water is drained outside through the upper frame.

Next, the rising piece 18 rises from an intermediate portion of the base wall 10 in the indoor and outdoor directions, and a horizontal receiving piece 21 protruding both indoors and outdoors is provided at the upper end so as to be higher than the inclined piece 16. ing. The outside projecting piece 21a of the receiving piece 21 is
To prevent mortar, dust and the like from entering the drainage channel 19 from above during construction. In addition, indoor side protruding piece 2
1b is provided with a vertical piece 21c whose tip is bent upward at a right angle. When water leaks into the upper surface of the receiving piece 21, the vertical piece 21c prevents entry into the room.

Next, as shown by the imaginary line in FIG. 2, the coking between the upper frame 3 and the frame 30 is such that the gap between the opening hole 31 and the upper frame 3 is a gap A (range of 15 mm to 20 mm) suitable for coking. applied to the case, when it becomes a secondary coking S ₂ to the primary coking S ₁ between the inclined piece 16 and outer wall 35 to be described later, the accuracy of the aperture hole 31 becomes worse gap B (or 20 mm) is Since the secondary coking S ₂ cannot be performed, the support rod 32 for mounting the window frame is welded to the mounting plate 33 a of the sliding member 33 and the mounting auxiliary member 34 of the frame 30, and the window frame is attached to the mounting plate 33 a. After fixing the mortar 2, the space between the gaps B is filled with mortar. The outer wall 35 on the outer surface of the skeleton 30 is also provided with a mortar attached to the skeleton 30, and a tile or the like is attached to the outer surface thereof to be integrated with the skeleton 30. In the gap between the outer wall 35 and the inclined piece 16, the space between the indoor side end 16 a of the inclined piece 16 and the receiving piece 21 at the back thereof is closed with a sealing member 36 such as a styrene foam. fill the gap primary coking S ₁ is applied.

Next, the operation of the above configuration will be described. When the primary coking S ₁ the outer wall 35 and the inclined piece 16 is defect rainwater reaches the interior end 16a up run down the inclined piece 16 the upper surface of the rising gradient by the pressure difference between the outdoor and indoor.
Here, the rainwater is cut off the path to the indoor side in the space of the drainage channel 19, drips down through the drainage channel 19 by its own weight at the indoor side end 16a, and directly from the drainage hole 20 of the base wall 10 or the outer shroud 6
Is drained to the outside of the room through the upper frame, preventing water leakage into the room. Thus to prevent water leakage into the opening hole 31 and the upper frame 3 and a clearance B is larger construction has been secondary coking S ₂ indoor fully rainwater even impossible for.
