Description

[Detailed Description of the Invention] This invention relates to a connection structure for a frame used as a sash frame or a door bag frame.

The lower frame of a sash frame or door pocket frame may not have enough strength to support itself, and to compensate for this, a common reinforcement method was to support the lower frame with L-shaped metal fittings. .

However, in this type of reinforcement, the part where the L-shaped metal fitting is attached to the frame is buried in the exterior wall, which requires a lot of work and has many problems in terms of rain protection and support strength.

Therefore, the object of this invention is to provide a frame mounting structure that can firmly support and fix the lower frame regardless of the exterior part.

This invention will be explained below with reference to illustrated embodiments.

FIG. 1 is a partially enlarged perspective view showing the connection between the longitudinal end of the lower frame 1 and the lower end of the short frame 2 and the connection support fitting 3. FIG.

The lower frame 1 has a hollow portion 4 at the base end thereof, and a mounting plate 5 extending upward and downward is provided at the base end face thereof.

Note that the intermediate portion 6 of this mounting plate 5 may not necessarily be provided.
It is important that the mounting plates 5.5 are provided above and below so that the mounting base end surfaces are fixedly supported by the frame 7, such as a pillar or wall, with an interval between the top and bottom.

Further, although the illustrated lower frame has a hollow base end portion and a rail 8 divided into two parts and connected by screws 9, they may be integrally formed.

On the lower wall of the mounting base end at the longitudinal end of the lower frame 1,
A notch 10 into which the connecting support 3 can be tightly fitted is provided.

The connecting support 3 includes a proximal support part 11 that can be tightly fitted into the hollow part 4 of the lower frame 1, and a distal end support part that is connected to this and can extend to the lower surface of the distal end of the lower frame 1 via the notch 10. 12, and the proximal support part 11 has screw holes 13.13 for connection with the short frame 2 and screw holes 14.1 for connection with the lower frame 1.
4 is provided.

Although the illustrated connecting support 3 is a hollow member, it may be a solid member such as a cast member.

When assembling the above configuration, as shown in FIG.
1 is inserted into the lower frame 1 by sliding it from the longitudinal end side.

In the fitted state, the proximal support part 11 is tightly fitted into the hollow part 4, the intermediate part 15 of the support 3 is in close contact with the inner end surface in the width direction of the notch part 10, and the upper surface of the distal end support part 12 is in contact with the lower frame. It will be attached to the lower surface of the tip of 1 and support the lower frame.

The connecting support 3 is fixed to the lower frame 1 by screws 16 passing through the lower frame 1 using the screw holes 14.

Next, the mounting plate 5 of the lower frame 1 is attached to a mounting frame 7 such as a wall or a pillar, and the upper and lower mounting plates 5 are fixed with nails 17 or screws.

Next, the lower end side of the short frame 2 is butted against the longitudinal end of the lower frame 1, and the screw 18 is inserted through the short root 2 using the screw hole 13.
to be integrated.

In this way, the base end support part of the connecting support 3 is tightly fitted into the hollow part 4 of the lower frame 1, and is fixed to the short roots 2 to support the lower frame 2, so that the load on the lower frame 1 caused by fittings etc. It is possible to sufficiently resist the bending moment caused by the bending force, and the support strength is definitely improved.

In addition, since the connecting support 3 also serves as a connecting member between the lower frame 1 and the short roots 2, assembly members can be omitted and assembly work can be facilitated.

In addition, since the attachment base end support part of the connection support 3 is completely fitted into the hollow part 4 of the lower frame 1, there is no relationship with the exterior wall 19 during installation, making the installation extremely easy. Become.

Next, the embodiment shown in FIGS. 4 and 5 will be described.

In this embodiment, other aspects except for the notch 10A are substantially the same as in the previous example.

That is, the notch 10A has a step shape (nail shape) that is interposed toward the end of the bottom frame 1 in the longitudinal direction of the bottom frame 1, and the narrow part 19 is open at the bottom frame end. It is located near the edge of the bottom frame.

When attaching the connecting support 3, insert the proximal support part 11 from the wide part 20 of the notch 10A, and then
After the proximal end support part 11 is fitted into the hollow part 4 by raising it up, it is slid in the longitudinal direction of the lower frame 1, that is, towards the narrow part 19, to achieve a tight fit.

Next, after fixing the lower frame 1 to the frame 7 in the same manner as in the previous embodiment, the short frame 2 is butted against the end of the lower frame 1 and integrated with the screws 18 using the screw holes 13.

By screwing the screws 18 into the screw holes 13 of the support 3, the ends of the lower frame 1 are pulled together by the support 3 and are clamped between the support 3 and the short frame 2. Therefore, since there is no need for special screws for connecting the short frame 2 and the lower frame 2, it is possible to simplify the machining process and the assembly work accordingly.

As described above, according to this invention, the support strength of the lower frame can be improved and construction can be easily performed.
