Description

[Detailed Description of the Invention] The present invention relates to a reinforcing member made of cast aluminum and used as a roofing material or a supporting material for a bay window.

As is well known, bay windows are installed protruding from the exterior wall of a building, so they are generally installed at the same time as the building is constructed.However, in recent years, with the development of unit construction methods for bay windows, many renovations are now adding only bay windows. It's being done. The first invention of this kind was in the 1970s.
A bay window disclosed in Japanese Patent No.-51868 is known, and a reinforcing member made of cast aluminum is used as a component thereof.

By the way, in the above invention, in order to fix the window part to the reinforcing member, bolts are inserted into the mullions of the window part, and both ends of the bolts are made to protrude from the end faces of the mullions, and each bolt end is connected to the reinforcing member. Each bolt is screwed on using two nuts, so the bolts must be longer than the mullions, and each screw requires multiple nuts, making the work time-consuming. It was hot.

This invention was made in view of the above circumstances,
By improving the reinforcing member used in this type of bay window, the above drawbacks could be overcome. The present invention will be explained below based on the illustrated embodiments.

In FIGS. 1 to 5, the reinforcing member of the present invention is made of aluminum casting, and in this example is used as the roof material 2 and lower support material 3 of the bay window 1.

The main body 5 of the reinforcing member according to the present invention has a shape that matches the planar shape of the bay window 1, and is provided with a plurality of ribs 6, 6 at positions corresponding to the window portions 4, 4 of the bay window 1. These ribs 6, 6 have the same horizontal plane position, and a screw hole 8 is screwed in the vertical direction from the end surface 7 of the ribs 6, 6. In addition, in Fig. 3, 9,
Reference numeral 9 indicates a reinforcing rib integrally formed at the base end of the main body 5, and reference numerals 10 and 10 indicate a reinforcing rib that connects the main body 5 to the outer wall of a building (not shown).
The elongated holes 11, 11 for bolts used for fixing the device are similar mounting holes. In this example, the ribs 6, 6 are formed at the same horizontal plane position, but if necessary, for example, the ribs 6, 6 may be formed at the end surfaces 7, 7 of the portions corresponding to the central window portion and both side window portions. It may be formed so as to provide a step. This is because when the cross-sectional shapes of the upper and lower frames of each window portion are different, an auxiliary member may be interposed in each frame.

When constructing a bay window using the reinforcing member of this proposal, it is necessary to assemble the window parts 4, 4 at the same time or afterward.
Bolts 12, 12 from the upper and lower frames 41, 42 of the window part 4
It is only necessary to insert the ribs 6, 6 and screw them into the screw holes 8, 8 of the ribs 6, 6. In addition, in FIG. 4, the lower frame 42
Since an auxiliary piece 43 is separately attached to the lower part of the auxiliary piece 43, bolts 12, 12 are inserted into this piece 43 and screwed onto the reinforcing member main body 5, thereby fixing the lower frame 42 to the auxiliary piece 43. However, the same applies when an auxiliary piece is used for the upper frame 41, and in short, the upper and lower frames 41, 42 may be directly or indirectly screwed onto the reinforcing member. Bolt 12 used at that time
It goes without saying that a normal nut may be used, and a separate nut is not required for screwing.

As explained above, the aluminum casting reinforcing member of the present invention has a shape that conforms to the planar shape of the bay window, has a plurality of ribs at positions corresponding to the window portion of the bay window, and furthermore, these ribs have a horizontal position. be equal,
In addition, since a screw hole is formed in the vertical direction from the end face, the construction work of the bay window is extremely simple and easy compared to the case where conventional bay window reinforcing members are used. .
