DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a bay window bracket in which a bracket for supporting a bay window is mounted on a window stand and a stud below an opening.

[0002]

2. Description of the Related Art A bracket for supporting a bay window and transmitting the load to a window base and a stud while supporting the bay window overlaps a lower surface of a base plate of the bay window and supports the same, and a support for the window base and the stud. It consists of legs to be joined, and is generally fixed from the outdoor side to the window stand and studs as shown in Japanese Utility Model Publication No. 5-29352, but the legs are studded by the plate thickness or the expected width. Because it protrudes from the outside surface of the vehicle, it interferes with the outer wall material, causing a problem of connection.

[0003] In this case, since the bracket is positioned by abutting the leg against the stud and the window sill,
Since the level cannot be accurately adjusted with respect to the base plate in advance, it is inevitably attached to the bay window. As a result, the installation must be performed while holding the bay window, and the workability decreases. .

[0004] Interference with the outer wall material of the bracket can be avoided by making the legs absent and mounting and fixing the end on the indoor side of the support portion on the window sill. Since the resistance element of the moment due to the load on the bay window is only the screw screwed into the window sill, the resistance to the moment decreases, and the tip of the bay window is likely to hang over time.

[0005] Since the window sills are usually only nailed to the studs, the studs cannot cooperate with the window sill in the above case, and the window sill alone resists the moment. As a result, it is easy to be twisted, and the tip of the bay window is hung down.

The present invention has been made in view of the above background, and proposes a mounting structure that has good workability and has high resistance to a moment while solving the problem of connection with an outer wall material.

[0007]

According to the present invention, a part of a window sill is cut out, and a leg of a bracket is inserted into the notch and joined to a side surface of a stud and a top end of the window sill to thereby form a connection with an outer wall material. The workability and the resistance to the moment are increased while eliminating the problem of the connection between the two, and the mounting accuracy is secured.

The notch is formed at the position on the stud of the window sill, spatially continuously from either side of the stud in the finding direction, from the outdoor side or from the indoor side.

The bracket overlaps the lower surface of the base plate to support it, a mounting portion that is continuous with the mounting portion and is mounted on the top end of the window sill, and a leg that depends from the mounting portion and overlaps the side surface of the stud. At the same time as the legs are inserted into the notches of the window sill and overlap the sides of the studs, the mounting part is placed on the top end of the window sill,
It is joined to studs and windowsills by screws.

Since the legs of the bracket overlap the side surfaces of the stud and are joined to the stud and the window sill, the stud does not protrude from the outdoor surface, and interference with the outer wall material is avoided.

Since the mounting portion of the bracket rests on the window, the bracket can be attached to the bay window, and the workability is improved.

Further, the bracket is mounted on the top end of the window sill in the mounting portion with the legs overlapping the side surfaces of the studs, so that the level adjustment with respect to the ground plate can be performed reliably, and the horizontal accuracy of the support portion is improved.

[0013] With respect to the moment due to the load applied to the supporting portion, in addition to the pull-out resistance of the screw penetrating the mounting portion, the shear resistance of the screw penetrating the leg portion resists the moment.
The resistance is higher than when only the pull-out resistance of the screw at the mounting portion is used.

The problem of the bracket protruding from the outdoor surface of the stud can also be avoided by notching the stud and the window sill from the outside corresponding to the legs. However, the vertical accuracy and smoothness of the notched surface are reduced. The degree of mounting directly affects the mounting accuracy and mounting strength of the bracket, and it is not easy to form a notch, so that improvement in mounting accuracy cannot be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a pillar 4, 4 around an opening shown in FIG.
A bracket 1 for supporting a main plate 6 of a bay window 5 projecting outward from the outside is attached to a stud 2 and a window stand 3.

As shown in FIGS. 1 and 3, the bracket 1 overlaps the lower surface of the base plate 6 and supports it. The support portion 11 is continuous with the support portion 11 and rests on the top end of the window base 3 and is joined thereto. And a leg 13 which is suspended from the mounting portion 12 and overlaps and is joined to any side surface 21 of the stud 2 in the finding direction. FIG. 1 shows an example of mounting the bracket 1 having the simplest shape. FIG. 3 shows a stud 2 below the mounting portion 12 of the bracket 1.
This is an example of attachment in a case where the abutment portion 14 abutting against the outdoor surface 22 is integrated, and the abutment portion 14 is joined to the stud 2 with the screw 7 to supplement the joining of the leg portion 13 to the stud 2.

As shown in FIG. 1, the window base 3 is spatially continuous with the side surface 21 of the stud 2 at the position on the stud 2,
A notch 31 into which the leg portion 13 is inserted is formed from the outdoor side or from the indoor side. The inner peripheral surface 32 of the notch 31 near the stud 2 should be flush with the side surface 21 of the leg of the bracket 1.
Although it is desirable in terms of stability of the leg 13, since the leg 13 is positioned with respect to the stud 2 by contacting the side surface 21, the inner peripheral surface 32
There is no problem even if is located closer to the center of the stud 2 than the side surface 21, and it need not be smooth.

The leg 13 of the bracket 1 has a notch 31 in the window sill 3.
The mounting portion 12 rests on the top end of the window sill 3 and is joined to the stud 2 and the window sill 3 by screws 7 respectively.

The bracket 1 is positioned by the leg 13 overlapping the side surface 21 of the stud 2 and the mounting 12 is placed on the window base 3 to ensure horizontal accuracy.

FIG. 4 shows the use state of the bracket 1 shown in FIG. 3. In this case, since the metal bracket 1 serves as a cold bridge or a hot bridge, the heat insulating material 8 is installed under the support portion 11. This reduces the decrease in the heat insulating effect. FIG.
FIG. 6 shows the case where the leg 13 is inclined toward the indoor side with respect to the support 11 in order to reduce the heat insulation loss at the leg 13 of the bracket 1 facing the outdoor under the heat insulating material 8. This shows a case where the whole is moved to the indoor side. In the case of FIG. 6, the notch of the window sill 3
31 is formed from the indoor side.

FIG. 7 shows the mounting procedure of the heat insulating material 8 installed under the support portion 11 of the bracket 1. As shown in FIG. It is adhered from below to the heat insulating materials 82, 82 installed on the lower surface, and covers the lower part of the support portion 11. The heat insulating material 82 and the heat insulating material 8 are both provided with an air layer provided between the support 11 and the heat insulating material 8. FIG. 9 shows a production example of the heat insulating material 8 shown in FIG. 8, in which the heat insulating material 8 is divided into two parts in the width direction and adhered to the heat insulating material 82 while being adhered to each other. An adhesive 81 such as a double-sided tape with a release paper is applied to a place where the heat insulating material 8 is adhered.

The bracket 1 applies a moment to the stud 2 and the window sill 3 by receiving the vertical load of the exit window 5, and the stud 2 and the window sill 3 receive a force to go around the outside of the room. In the stand 3, since the notch 31 becomes a weak point and is easily deformed, in FIG. 5 and FIG. 6, in order to compensate for the lack of rigidity of the notch 31, the window stand 3 has a horizontal rigidity as shown in FIG. It is connected to the large base plate 6 by the connecting tool 9 on the indoor side,
The deformation of the window sill 3 is prevented.

FIG. 6 shows an embodiment in which the frame is a two-by-four structure.
Since the plywood is stretched first on the outside of the room with the vertical frame corresponding to, and the gypsum board is stretched on the inside of the room after the bay window 5 is installed, it is difficult to form the notch 31 from the outside of the room as described above. , Formed from the inside of the room, and the leg 13 is accommodated therein.

In the embodiment shown in FIG. 4, a level adjusting member 15 connected to a lower frame 10 of an opening frame installed in the bay window 5 is integrated with a front end of the support portion 11 of the bracket 1 on the outdoor side to adjust the level. The bending deformation of the support portion 11 is corrected by adjusting the distance between the member 15 and the lower frame 10.

[0025]

The present invention is as described above. A part of the window stand is cut out, the leg of the bracket is inserted into the notch, and the mounting portion is placed on the window stand, and the side of the stud is removed. Since the studs are joined to the top of the window sill, the studs do not protrude from the outdoor surface, and the bracket can be attached to the bay window so that the workability of mounting the bracket can be improved while avoiding interference with the outer wall material. Can be.

Further, since the bracket is mounted on the top end of the window sill in the mounting portion in a state where the leg portion overlaps the side surface of the stud, the level adjustment with respect to the ground plate can be performed reliably, and the horizontal accuracy of the support portion is improved.

The moment caused by the load applied to the support portion is resisted by the shear resistance of the screw penetrating the leg portion in addition to the pull-out resistance force of the screw penetrating the mounting portion. More resistant than if.
