Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a cross-frame cover, ie, a blind cover, to a cross-frame, for example, a curtain wall blind.

Traditionally, in curtain walls, watertight performance has been ensured by introducing outside air into the internal space of the groove for installing panels such as glass installed on the upper side of the horizontal frame and making the pressure equal to the outside pressure. There is.

As shown in Japanese Utility Model Application Publication No. 55-22406 and Japanese Utility Model Application No. 56-97417, outside air introducing means is provided with a protruding piece for attaching a ridge and a ridge attached to the ridge. A space with a downward opening is formed between the panels and the projecting piece is partially cut out to form a path for introducing outside air into the panel mounting groove.

However, in such outside air introduction means,
It is necessary to cut out the protruding piece for attaching the rim, which is provided in a blank section, and generally, cutting a long and heavy blank material with a large cross-sectional area is a very troublesome work, and it is difficult to perform the work at the processing site. It was a factor that inhibited sexuality.

The present invention aims to provide a horizontal frame that can improve workability at a processing site and ensure sufficient watertightness in a horizontal frame that has a structure in which panels are attached using such ribbed edges. For this purpose, the structure is uniquely designed.

That is, the present invention provides a horizontal frame in which an external push edge is attached to the horizontal frame body to form a panel mounting groove that opens on the top surface, and the internal space of the panel mounting groove is made to have the same pressure as the outside air pressure. A plurality of horizontal frame cover fixing devices are provided, each of which includes a main body that is attached to the top surface of a wall, a space holding part that protrudes toward the outdoor side of the main body, and a horizontal frame cover locking part that is provided on the outdoor side of the space holding part. , are attached at suitable intervals to the ridge locking portions provided on the upper surface of the prospective wall of the horizontal frame main body, and the outer ridge has a substantially L-shaped cross section, and its horizontal portion corresponds to the mounting position of the horizontal frame cover fixture. A cutting part for avoiding is provided, and a cutting part for introducing outside air is provided in the rising part, and the horizontal part of the outer ridge is engaged with the ridge locking part, and the space retaining part is removed from the cutting part for avoiding. The horizontal frame cover is in a state of protruding toward the outside of the room, and the horizontal frame cover locking part located above the outside air introduction cutout of the outer edge and the horizontal frame cover locking part of the horizontal frame cover mounting tool are used to attach the horizontal frame cover. The invention is characterized in that a downwardly opening space for introducing outside air is formed between the horizontal frame cover and the horizontal frame.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

First, FIG. 1 shows a curtain wall 1 constructed based on the isobaric theory. This curtain wall 1 has a plurality of mullions 2 arranged in parallel in the vertical direction, and mullions 6 serving as horizontal horizontal frames are installed between them at appropriate intervals. A window glass 4, which is a panel, is fitted between the windows 6 and a horizontal frame cover, that is, a window cover 5, is attached to the outdoor side of the window 6.

As shown in Figures 2 to 4, Mume 6 is
Panel mounting grooves 38 and 39 are provided at the top and bottom of the horizontal frame main body 3 across the projected wall 17, and the panel mounting groove 38 that opens on the upper side is located on the horizontal frame projected wall 1.
A rising wall 19 is connected to the indoor side of the wall 17, and an outer ridge 10 is locked to two ridge locking parts 7, 7 which are longitudinally protruded from the upper surface of the prospective wall 17 on the outside side.
formed by.

The outer edge 10 has a substantially L-shaped cross section, and its horizontal portion 1
Engagement pawl 1 corresponding to the ridge locking portions 7, 7 on the lower surface of 0a
2 and 12, and a holding groove 28 is integrally formed on the indoor side above the rising portion 10b, and an upward horizontal frame cover locking portion 14 is integrally formed on the outdoor side. In addition, this outer edge 10 has a cutout part 11 for avoiding attachments formed in a horizontal part 10a at a position corresponding to the attachment position of a horizontal frame cover attachment 8, which will be described later, and a rising part 10b at an appropriate interval. Cutout part 29 for introducing outside air for equal pressure
is formed as a punched hole.

In addition, the above-mentioned open space 6 forms a hollow part 18 on the lower surface of the indoor side of the prospective wall 17, and also forms a hollow part 18 on the lower surface of the indoor side wall 2 of the prospective wall 17.
0 to form a panel mounting groove 39 with an opening on the lower surface. This eyeless part 3 has a fixing screw 21 at the end on the indoor side.
It is attached to the side surface of the mullion 2 by an L-shaped mounting bracket 22 and a mounting screw 23.

The horizontal frame cover fixture 8 has a hollow main body 26 that also serves as panel support, and a horizontal space holding part on the outdoor side of the lower end of the vertical wall 8a that contacts the outdoor wall 20 of the horizontal frame main body 3. 8b is provided in a protruding manner, and has an upward horizontal frame cover locking portion 13 at its tip.
The main body portion 26 has rib locking portions 7, 7 on its lower surface.
It has locking pawls 9, 9 that lock into it, and a glass bottom plate 27 is provided on the upper surface thereof. Further, the vertical wall 8a is provided with a vertically elongated screw insertion hole 24 that opens downward, and allows an auxiliary mounting screw 25 to pass therethrough. When the screw 25 is shipped from the factory, the mounting tool 8 is attached to the lug locking portion 7,
It is temporarily fixed to prevent it from coming off.

In addition, at the time of shipment from the factory, the outer ridge 10 is also attached to the ridge locking portions 7, 7, and is prevented from being removed unnecessarily by a fixing device (not shown).

Then, at the construction site, the outer rim 10 is removed, the screws 25 are loosened, the fixture 8 is removed, and the glass 4 is assembled between the two stands 2, 2 and the upper and lower blinds 6, 6, and then the glass bottom plate 27 is installed. The installed horizontal frame cover fixture 8 is locked to the edge locking parts 7, 7 with its locking claws 9, 9, and then the glass 4 is placed on the glass bottom plate 27. Incidentally, by tightening the screws 25 into the horizontal frame main body 3, the horizontal frame cover fixture 8 can be more securely fixed.

Next, the outer ridge 10 is locked to the ridge locking parts 7, 7 by the engaging claws 12, 12. At this time, the outer edge 1
0 is provided with a cutout 11 for avoiding the attachment at a position corresponding to the horizontal frame cover attachment 8, so that the attachment can be reliably performed without interfering with the horizontal frame cover attachment 8. With this attachment of the outer rim 10, the glass 4 can be moved between the gasket 30 held in the retaining groove 28 of the outer rim 10 and the gasket 31 held in the retaining groove 33 provided at the tip of the horizontal portion 32 of the rising wall 19. held between. In addition, the upper end of the window glass 4 is connected to the hollow part 18 of the blind 3 and the hanging plate 2.
It is held within the panel mounting groove 39 by a pair of gaskets 35 and 36 held in the holding grooves 33 and 34 of 0.

The cover 5 has a lower locking claw 16 at the interior side intermediate portion of the main body portion 5a facing the horizontal frame body 3, which corresponds to the horizontal frame cover locking portion 13 of the horizontal frame cover mounting fixture 8, and an upper locking claw 15 at the upper end portion, which corresponds to the horizontal frame cover locking portion 14 of the outer shim 10. The cover 5 is attached to the exterior side of the cover 5 and the outer shim 10 by these locking claws forming a predetermined outside air introduction space 37. This space 37 opens downward and communicates with the internal space of the panel mounting groove 38 by the outside air introduction cutout portion 29, so that this space communicates with the outside air through the space 37 and is at the same pressure as the outside air. In other words, the curtain wall 1 prevents rainwater from entering the panel mounting groove 28 based on the equal air pressure theory.

In addition, since what is shown is one example, the cross-sectional shape and detailed shape of the horizontal frame main body 3, the horizontal frame cover fixture 8, the outer rib 10, and the blind cover 5 are not limited to those of the example.

According to the present invention, in order to introduce outside air into the panel mounting groove of the horizontal frame, the horizontal frame cover is provided using the outer push edge and a plurality of horizontal frame cover fixing devices provided at appropriate intervals, and the horizontal frame cover and the horizontal frame cover are installed. A space for introducing outside air is formed between the frame and the frame, and unlike the conventional method, a protruding piece for attaching a rim that protrudes directly to the outdoor side of the horizontal frame body is not used. Therefore, there is no need to cut out the protruding piece to form the outside air introduction section.
On the contrary, since the outer rim, which generally has a small cross-sectional shape, is cut out, there is no need to handle the horizontal frame, which has a large cross-section and is heavy in weight, which greatly improves work efficiency at the processing site.

In addition, since the horizontal frame cover fixtures are installed using the rib locking parts provided on the horizontal frame body in the same way as the outer ribs, their installation structure is simple, and they can be easily adjusted to the wind blowing condition. Therefore, even if negative pressure is applied to pull the horizontal frame cover toward the outdoor side, both the outer rim and the horizontal frame cover attachment are locked to the rim locking parts, so the locking is not integral with them. There is no risk that the related horizontal frame cover will come off unnecessarily.
