Description

[Detailed description of the invention] This invention relates to a device for attaching eaves to the exterior wall of a building, and is particularly suitable for attachment to exterior walls made of ALC (lightweight foamed concrete) panels and RC (reinforced concrete) panels. This invention relates to an eaves mounting device.

Traditionally, when eaves are attached externally to a building's exterior wall, watertightness between the building's exterior wall surface and the base end of the eaves is a problem, especially when it comes to exterior walls made of the ALC and RC panels mentioned above. However, it has been difficult to obtain a good watertight structure due to poor workability, which is an essential defect of RC panels. Also, something like this
Due to the poor workability of ALC and RC panel exterior walls, it is extremely difficult and costly to install eaves.
Furthermore, in the case of an ALC panel which is a fragile material, simply bolting the base end of the eaves to the outer surface of the outer wall would not be strong enough to bear the weight of the eaves.

The present invention was created in view of the above, and provides an eaves mounting device that can ensure good watertightness, is easy to install, and provides sufficient strength even in the case of external walls made of ALC or RC panels. It is intended to.

The gist of the present invention in accordance with the above-mentioned purpose is to attach a mounting plate, which has a drainer integrally connected to the upper edge in a substantially T-shaped longitudinal section and a hook portion protruding from the upper edge of the outer surface, to the outer wall of a building. It is fixed to the outer surface with a fixing tool, and the inner end of the draining plate is inserted into a groove formed in the outer surface of the outer wall body, and the hooking part of the mounting plate is attached to the base end of the eaves. The provided hook part is hooked, and the eave is fastened to the outer wall using bolts that pass through the outer wall and the mounting plate.

Next, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, 1 is an outer wall of a building made of ALC panels, and 2 is a window opening opened in this outer wall, into which a window frame 3 is fitted. Reference numeral 4 denotes a window eave, which is installed on the outer wall 1 slightly above the window opening 2. Reference numeral 5 denotes a rectangular mounting plate having a shape that almost corresponds to the shape of the base end (the end surface facing the outer wall 1) of the eaves 4, and a drainer 6 extends over the entire upper edge of the mounting plate 5. They are integrally connected to each other so as to form a substantially T-shape in longitudinal section. In this drainer 6, a portion 6a protruding from the inner surface of the mounting plate 5 (the side facing the outer wall 1) has a horizontal portion and a vertical portion forming a substantially L-shaped cross section, and a portion 6a protruding from the outer surface of the mounting plate 5. The protruding portion 6b forms a downward slope. Also, on both side edges of the mounting plate 5, as shown in FIG.
A letter-shaped protruding portion 5a is integrally provided, and a hooking portion 7 having a substantially L-shaped cross section is integrally provided at the upper end of the outer surface of the mounting plate 5. Reference numeral 8 denotes a groove recessed in the outer surface 1a of the outer wall body 1, and the groove 8 has a U-shaped cross section and is along the upper side and both sides of the mounting plate 5 when viewed from the front. It is shaped like a downward U-shape. However, the mounting plate 5
is in contact with the outer surface 1a of the outer wall body, and the drainer 6
The L-shaped inward protruding portion 6a and the L-shaped protruding portions 5a on both sides of the mounting plate 5 are fitted into the groove 8, and the mounting plate 5, the inward protruding portion 6a, and the protruding portion 5a are fitted into the groove 8.
are each fixed to the outer wall body 1 at an appropriate number of locations using hole-in anchors 9 (other bolts, screws, etc.) as fixing devices. The mounting plate 5 and the drainer 6 are integrally formed of a metal material such as aluminum, and are made of an extruded aluminum alloy material, for example.

As is clear from FIGS. 1 to 3, the eaves 4 includes a plurality of hollow intermediate support frames 10 made of extruded aluminum alloy material, for example, and a similar extruded material. A hollow peripheral frame body 11 that also serves as a decorative picture frame, and an upper plate 1 made of a flat plate of aluminum alloy or the like.
2, a bottom plate 13 made of synthetic resin or the like, a support plate 14 made of the same material as the top plate 12 and laid on the top surface of this bottom plate 13, and an aluminum alloy placed on the base end surface of the eaves 4. Base end plate 1 made of extruded material
As shown in FIG. 1, the peripheral frame 11 is integrally connected to the intermediate support frame 10 by screwing into the bis pockets 10a, 10a of the intermediate support frame 10 with screws 16, As shown in FIGS. 1 and 2, the proximal end plate 15 is integrally connected to the intermediate support frame 10 by screwing into the bis pockets 10a, 10a of the intermediate support frame 10 with screws 17,
Further, the top plate 12 is properly fitted to the peripheral frame 11, and the bottom plate 1
3 is appropriately fitted to the peripheral frame 11 and the base end plate 15. The base end plate 15 is provided with a hook portion 18 having a horizontally L-shaped cross section that can be hooked to the L-shaped cross-section hook portion 7 of the mounting plate 5 on the upper edge thereof, protruding in the direction facing the outer wall body 1. In addition, there are a plurality of ribs 19 below.
are protruding in the same direction. Note that a lid frame 11a is attached to the upper surface side of the peripheral frame body 11. Also eaves 4
The inside is usually filled with urethane foam or the like.

In order to attach the eaves 4 having the above structure to the outer wall 1, the mounting plate 5 and the drainer 6 are fixed to the outer surface 1a of the outer wall 1 as described above, and then the base end of the eave 4 faces the mounting plate 5. Then, the hook portion 18 at the upper end of the base end plate 15 is hooked to the hook portion 7 on the mounting plate 5 side, and the eaves 4 is left on the mounting plate 5, that is, in a temporarily placed state. From such a temporarily placed state, bolts (not shown) on the inner surface of the outer wall 1 ( Insert the through bolt 20 from the indoor side), screw the outdoor side protruding end of the bolt 20 into the bis pocket 10b of each intermediate support frame 10 of the eaves 4, and tighten the bolt 20 from the indoor side. , the intermediate support frame 10 is pulled toward the outer wall, and the entire eave 4 is moved to the outer wall 1 with the tip of each rib 19 of the base end plate 15 pressed against the outer surface of the mounting plate 5.
This means that it is integrally attached and fixed to the body.
Although not shown, the base end plate 15 is also provided with a bolt insertion hole through which the through bolt 20 can be inserted. Further, a seat plate 21 for supporting the head of the bolt 20 is provided on the inner surface 1b of the outer wall body 1.

After being attached to the outer wall body 1 of the eaves 4 in this way, the inside of the groove 8 and the inclined outward protruding portion 6b of the drainer 6 are
Sealing materials 22 and 23 are respectively loaded into the space covered by the base end plate 15, and a sealing material 24 is also installed into the gap between the lower end of the base end plate 15 and the outer surface of the outer wall body.

As explained above, the present invention is designed to attach a mounting plate to the outer surface of a building's outer wall, in which a drainer is integrally connected to the upper edge in a substantially T-shaped longitudinal section and a hook is protruded from the upper end of the outer surface. At the same time, the inner end of the draining plate is inserted into a groove provided in the outer surface of the outer wall body, and the hooking part of the mounting plate is provided with a groove provided at the base end of the eaves. Since the eaves are fastened to the outer wall with bolts that pass through the outer wall and the mounting plate, the base end of the eave and the outer surface of the building's outer wall can be connected by draining. The upper surface of the gap is covered, and the inner end of the drainer is embedded in the outer wall, making it possible to significantly improve the watertightness of the gap. By hooking the hooking portion to the hooking portion of the mounting plate, there is no need to hold the eaves at all, which saves time and effort, and allows the installation work to be carried out easily and easily. In particular, in this invention, the load of the eaves is ultimately borne by the through bolts that penetrate the outer wall, so the mounting plate does not need to be firmly fixed to the outer wall, and therefore the ALC panel The mounting plate can be relatively easily attached to an exterior wall made of a steel or RC panel, and since the eaves itself uses the above-mentioned through bolts, attachment to the exterior wall can be done reliably, firmly, and easily.
