Description

[Detailed explanation of the idea] The present invention relates to a window holder for a terrace bay window.

In some cases, a so-called terrace is provided in a part of the garden facing the house, and is made of paving stones or a concrete floor that extends from the house to the outside, and a bay window is built on this terrace, using this terrace as a base.

When installing the bay window itself on the terrace foundation, it is necessary to install a window holder for the bay window.
Conventionally, this window holder was made by bending an aluminum or steel plate and then welding or screwing it together to form a support frame for a window frame for a bay window and a frame for indoor and outdoor drainage. However, with this conventional structure, it rusts in a short period of time, making it look unsightly, and its poor insulation properties cause room temperature heat dissipation in cold regions, and it also requires a lot of processing steps, making it expensive. There was a problem.

The present invention focuses on the above-mentioned difficulties and attempts to provide a window holder for a terrace-type bay window that has excellent heat insulation, is lightweight, and has high strength. It is a band-shaped window holder 2 that extends along the periphery so as to match the periphery, and has core materials 14a, 14b, and 14c made of plywood, square timber, or foamed synthetic resin inside, and is made of reinforced plastic. The window holder outer shell part, which is integrally covered with the stand outer shell part 15 and which covers the core material, forms an outdoor side draining wall part 2b, a horizontal wall part 2a on the indoor side from this, and an indoor side draining wall. 2d, and at least the horizontal wall portion 2a is covered with a core material 14a having high compressive strength, so that the horizontal wall portion serves as a window frame mounting wall portion.

One embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a terrace-type bay window having a trapezoidal shape in plan view. It consists of a band-shaped bay window unit window holder 2 of the present invention that is attached along the belt and a bay window window frame part 3 that is interposed between the two, and the window frame part 3
It consists of a front window frame part 3a to which a sliding window shoji 4a is attached, and a side window frame part 3b to which casement window shojis 4b are attached on both sides.

As shown in more detail in FIGS. 4 to 6, the bay window frame 3 includes a base hollow mullion 6b made of synthetic resin that stands upright along the outer surface of the building wall 5, and a base hollow mullion 6b that is suitable for the outdoor side. Front hollow mullions 6b also made of synthetic resin stand upright in the interval, and are fitted into these hollow mullions and fixed to the roof frame 1 and window pedestal 2 at their upper and lower ends with nuts 7a and 7b. through bolt 8
A window frame member is fixed to both sides of each hollow mullion 6a, 6b by screws 10 via an adhesive 9 which also serves as a sealing material, and the four circumferential corners are integrally connected in advance by heat welding. It consists of a frame member 11 made of synthetic resin and a front mullion 6.
The window sash 4a is attached to the window frame member 11 attached to the base mullion 6a, and the casement window shoji 4b is attached to the window frame member 11 attached to the base mullion 6a. Note that the window frame member 11 is formed from a hollow material,
A metal material 12 such as aluminum for reinforcement is appropriately inserted inside.

The window holder 2 for a bay window according to the present invention is shown in Fig. 5 and below.
In particular, as shown in FIG. 7, the horizontal wall is formed to extend in a band shape so as to match the peripheral edge shape of the terrace foundation 13, that is, the trapezoidal shape in this embodiment, and is an attachment part to the terrace foundation 13 in its cross-sectional shape. 2a, an outdoor drainage wall 2b extending downward in an L-shape from the outdoor end of the horizontal wall, and a mounting flange 2 hanging further downward from the drainage wall 2b.
c, and an indoor drainage wall 2d extending upward in an L shape from the indoor end of the horizontal wall, plywood is used as a core material 14a for the horizontal wall 2a,
Foamed synthetic resin (injected foamed with urethane resin) is used as the core material 14b for the outdoor drainage wall section 2b, and preservative-treated square wood is used as the core material 14c for the indoor drainage wall section 2d. Material 1
4a, 14b, and 14c are integrally covered by a window holder outer shell 15 made of reinforced plastic, and the mounting flange 2c is integrally formed by the outer shell, so that the approximate cross section is stepped. As,
It is formed into a window pedestal unit that extends in the longitudinal direction in the form of a strip. At this time, each core material 14a, 14b,
Instead of forming the core material 14c from a different material as described above, the core material 14c may be formed from a deformed pipe or shape made of aluminum or steel, or other bent products of these metal plates.
a, 14b, and 14c may be integrally formed, for example, in the substantially stepped shape shown in the figure, and these may be covered by the outer shell portion 15.

As described above, the outdoor side draining wall 2b, the horizontal wall 2a, and the indoor side draining wall 2d are integrally formed by the window holder outer shell 15 that encloses the core materials 14a, 14b, and 14c. Of these, the horizontal wall portion 2a serves as a window frame mounting wall portion to which the bay window window frame portion 3 is attached as described later, so it is necessary to pay particular attention to the load strength of this wall portion. Therefore, at least in the horizontal wall portion 2a, the core material 14a enclosed in the window holder outer shell portion 15 must be made of a material with high compressive strength. In this embodiment, plywood is used as the core material 14a, but since foamed synthetic resin with a high degree of foaming, which is generally used as a heat insulating material, has a large compressive strain, it is necessary to use it as the core material of the horizontal wall portion 2a. This should be avoided as it may cause distortion of the window frame to which it is attached.
Of course, as described above, as long as a core material with high compressive strength such as plywood is used for the horizontal wall portion 2a, core materials of the same material may be used for the other wall portions 2b and 2c.

Furthermore, a decorative shaped portion 16 and a draining protrusion 17 are appropriately formed on the outer surface of the outdoor side draining wall portion of the outer shell portion 15. The outer shell part 15 of the window pedestal is formed using a well-known reinforced plastic molding method, for example, by stacking glass fiber cloth or glass fiber mat on the upper surface of the mold by adding a catalyst and accelerator to polyester resin and applying a roller to the mold. Therefore, it is possible to use a so-called hand lay-up method in which the material is molded into a desired shape, or a spray-up method in which it is formed by spraying with a spray gun.

Similarly, the roof frame 1 for a bay window has an outer shell part 1a made of reinforced plastic and a hollow part on the back surface surrounded by the outer shell part 1a, in which a urethane resin 18 is applied.
The insulation part 1b and the roof outer shell part 1 are formed by injection foaming.
A core material 19 such as plywood, glass fiber pine, metal plate, synthetic resin board, hardboard or particle board is attached to the outer shell part 1a at the base and tip of a.
It consists of mounting wall portions 1c and 1d integrally covered by.

To assemble the bay window, with the roof frame unit 1 facing backwards, one end of the through bolt 8 is fixed upright to the nut 7a in advance on the mounting wall 1d, and then the through bolt 8 is fixed as described above. Insert the mullions 6a and 6b of the window frame 3 for a bay window that has been assembled into a frame, and attach the other end of the through bolt 8 to the horizontal wall 2a, which is the window frame mounting wall of the window holder 2, with a nut 7b. At this time, as shown in FIG. 5 or 6, the generally U-shaped frame 21 having the bolt tightening space 20 is also fixed, and as shown in FIG. Window frame members 11a, 1 which are upper and lower horizontal frames of section 3
1b to each mounting wall portion 1d of the roof frame 1 and window pedestal 2,
By fixing to 2a with screws 22, a terrace-type bay window is manufactured as one unit.

When this terrace-type bay window unit is installed at the site, the base end surface of the roof frame 1 is placed against the outer surface of the building wall 5, and the mounting base 23 of the terrace foundation 13 is
and attach the mounting wall 1c of the roof frame 1 to the building wall 5.
In addition, the mounting flange portion 2c of the window holder 2 is fixed to the mounting base 23 with bolts 24 and 24, respectively, the exterior material 26 is attached, the sealing material 27 is filled, and the ceiling plate 28 and floor plate 29 are attached on the indoor side. In this case, the terrace-type bay window is completed, but at this time, in cold regions, etc., the window pedestal 2 may be installed so as to protrude 10 to 1000 cm above the floorboard 29, as shown in Fig. 5. In particular, it is possible to effectively prevent heat from radiating outside through the window glass opening, especially when the room temperature is near the floor surface.

As described above, according to the present invention, the outer shell of the window holder for terrace-type bay windows is made of reinforced plastic, so it is lightweight, has excellent heat insulation properties, and is also excellent in strength. Moreover, it is possible to maintain good appearance over a long period of time without fear of rusting.

Furthermore, a core material such as plywood, square lumber, or foamed synthetic resin is contained inside the outer shell of the window holder,
Since these are integrally encapsulated by the outer shell, it has greater durability against shock and vibration to the window holder, which is unique to terrace-type bay windows, and the window holder is made of expensive reinforced plastic. The outer shell of the table can be made thinner, which allows it to be manufactured more lightweight and at a lower cost.

Moreover, according to the present invention, the outdoor side drainage wall part, the horizontal wall part on the indoor side from this, and the indoor side drainage wall part are integrally formed by the outer shell part of the window holder that encloses the core material. There is no need to worry about water leaking into the room, and it has the effect of maintaining good rain control over a long period of time.

In particular, according to the present invention, at least the horizontal wall portion of the wall portions is covered with a core material having high compressive strength and the horizontal wall portion is used as the window frame mounting wall portion. A reinforced plastic window holder that does not cause distortion or deformation even when a large load of a roof frame is applied to a horizontal wall part can be manufactured, and can be stably used for a long period of time.
