Description

[Detailed description of the invention] (Field of application of the invention) This invention is used in the field of mounting devices for unit bay windows installed in general houses and high-rise buildings.

(Prior art) Bay windows, especially unit bay windows, are manufactured by assembling a roof frame for a bay window, a window frame for a bay window, and a window holder for a bay window in advance, and fitting these into a window installation opening made in a building frame.
The bases of the roof frame, window frame, and window holder are fixed to the building frame around the opening by bolts, etc., but at the time of construction, errors in the construction of the building frame or During long-term use, the bay window, which is formed by protruding from the building frame to the outside, may sag by an α degree due to distortion of the building frame or bay window, or loosening of the fastened parts between the two, as shown in Figure 2. This results in poor appearance, difficulty in opening and closing window shoji, and rainwater infiltration. Conventionally, in order to prevent this bay window from sagging, the parts that attach to the building frame were reinforced, and the bay window, especially its roof and window pedestal, were made to have a rigid structure made of cast metal as much as possible.

However, simply reinforcing the fastening parts or increasing the strength of the bay window itself cannot prevent the bay window from sagging due to distortion in the building frame.

(Problems to be solved by this invention) Therefore, this invention attempts to form a bay window in an accurate horizontal state even if distortion occurs on the building frame side.

(Means for Solving the Problems) In order to solve the above problems, in this invention, a bay window roof frame 2 is attached to the upper part of the bay window window frame 1, and a bay window window holder 3 is attached to the lower part of the bay window window frame 1. In the bay window in which the bases of the window frame 1, the roof frame 2, and the window pedestal 3 are fixed to the building frame 4, a reinforcing hardware 5 is provided inside the window pedestal 2 for the bay window. The window frame 1 is directly or indirectly supported by the reinforcing hardware 5 through the window holder 3, and the reinforcing hardware 5
is fixed to the building frame 4 directly or indirectly through the base plate 11 fixed to the upper end of the reinforcing hardware 5, and an adjustment bolt 6 is screwed into the lower end of the reinforcing hardware 5. By being supported in contact with the building frame 4, the reinforcing hardware 5 is attached to the building frame 4.
The structure is such that it can be lifted upward using the fixing point O as a fulcrum.

(Function) As shown in Fig. 3, by increasing the screwing amount of the adjustment bolt 6 screwed into the reinforcing hardware 5, the adjustment bolt 6 strongly presses against the building frame 4, and the reaction force is used to strengthen it. The hardware 5 is lifted upward using the fixing point 0 relative to the building frame 4 as a fulcrum, and as a result, the bay window frame 1, which is reinforced and supported by the reinforcing hardware 5, is moved upward and adjusted, and the bay window window frame that is almost hanging down is adjusted. 1 will be corrected to the horizontal state.

(Embodiment) In FIGS. 1 and 2, reference numeral 1 denotes a window frame for a bay window, and a lattice-patterned window sash 7 is attached within the window frame. A bay window roof frame 2 is attached to the upper part of the bay window window frame, and a bay window window holder 3 is attached to the lower part of the bay window frame, and the bases of these window frames 1, roof frames 2, and window holders 3 are attached to the building frame 4. Although not shown, it is fixed via a mounting hardware or by bolting.

In FIGS. 3 and 4, the window holder 3 for a bay window is formed into a hollow frame shape by aluminum casting or aluminum extrusion, and a steel plate is bent into the hollow part 8 and fastened with bolts 9 as appropriate. A reinforcing metal fitting 5 formed into a rigid structure is attached thereto. Specifically, the building frame side flange portion 5a of the reinforcing hardware 5 is fixed to the window holder 3 with bolts 10, and the reinforcing hardware 5 is fixed to the window holder 3 with bolts 10.
The upper flange portion 5b is fixed to the base plate 11 with bolts 12. An angle-shaped mounting bracket 13 is fixed to the base side of the base plate 11 with bolts 14, and this mounting bracket 13, an anchor bracket 15 and a bolt/nut 16 whose base end is fixed to the building frame 4 in a buried state. By being fixed to the base plate 11, the base plate 11 is fixed to the building frame 4. A decorative board 17 is appropriately layered on the base plate 11. Also, the upper flange portion 5 on the tip side of the reinforcing hardware 5
A window frame 1 for a bay window is mounted on c, and the window frame 1 is reinforced and supported. The window frame 1 has a mounting piece 1
8 is extended and fixed to the base plate 11 with bolts 19 to connect the window frame 1 and the base plate 11 to each other.

An angled reinforcing flange 5d is integrally formed at the lower part of the base end of the reinforcing hardware 5, into which an adjustment bolt 6 is screwed toward the building frame, and its tip abuts against the building frame 4. . Note that a nut-like body 6a is fixed to the tip by welding,
Care has been taken not to dig into the building frame 4, and a nut-like body 6b is also welded to the reinforcing flange portion 5d to form a female threaded portion for screwing in the adjustment bolt. 6c is a lock nut. Reference numeral 20 denotes an opening for adjustment operation provided through the window holder 3. Furthermore, 21 is a spacer for adjusting the distance between the base plate 11 and the building frame 4.

By inserting a working tool such as a wrench through the adjustment operation opening 20 and screwing the adjustment bolt 6 toward the building frame, the adjustment bolt 6 strongly presses against the building frame 4 and is reinforced by the reaction force. The metal fitting 5 slightly moves upward using its upper end, more specifically, the fixing point O near the mounting bracket 13 at the base end of the main plate as a fulcrum, and thereby the upper flange 5c of the reinforcing metal fitting 5 on the tip side. The mounted bay window window frame 1 is lifted slightly upwards, thereby correcting the entire bay window portion to accurately horizontally protrude from the building frame.

(Effects) According to this invention, distortion occurs in the building frame due to erection errors and external loads due to long-term use.
Therefore, even if the bay window part is hanging down, by operating the adjustment bolt, it can be reliably and accurately corrected so that the bay window part extends horizontally.
