Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a metal fitting used for attaching a frame such as an aluminum window frame to a base frame having a groove-shaped cross section.

[0001]

2. Description of the Related Art In a building such as a prefab house, when an aluminum window frame is mounted on a wall, a rectangular base frame is fixed to a window hole of the wall, and the window frame is mounted on the base frame.

A base frame is made of a frame member made of a channel having a U-shaped cross section. The upper and lower two horizontal frame members and the right and left vertical frame members are arranged such that the grooves of each frame member face inward. They are connected so that they are open. Then, the wooden block is hammered into the inside of the frame material with a hammer, or the wooden block is fastened to the inside of the frame material with a drill screw, and the window frame is fastened to this wooden block with screws.

[0003]

Incidentally, there are several types of plate thicknesses of the base frame, and therefore the groove width dimension is different depending on the type. Further, the groove width of the base frame may be different due to a processing error of the channel steel as a material.

[0004] Further, the wooden block has processing errors, shrinkage due to drying, expansion due to moisture absorption, and the like, and its dimensions are not always stable. Also, wooden blocks
Generally, the elastic deformation rate due to compression is small, and large elastic deformation cannot be expected.

[0005] As described above, the wooden block is struck into the base frame due to the difference in groove width of the base frame, the dimensional instability of the wooden block, and the low deformation rate of the wooden block. It cannot be hammered in, or the ground frame is deformed by forcibly hammering it, resulting in poor standing or poor waterproof performance.On the contrary, the width of the wooden block is too small compared to the groove width of the ground frame, making it impossible to install. Sometimes it was.

Further, when a wooden block is previously mounted on a base frame at a factory, a portion of the base frame into which the wooden block is fitted is caulked inward so that the wooden block does not come off due to vibration during transportation or the like. Inevitably, there was a problem that this took a lot of trouble.

On the other hand, the method of fastening a wooden block to a base frame with a drill screw is excellent in the stability of mounting, but has a problem that a large amount of labor is required for screwing work.

[0008] In either method, the nature of the wooden block is that it has low fire resistance, that it is easily corroded by dew condensation, or that other members such as shutters are fastened to the side plate of the base frame with screws. In doing so, there was a problem that the screws interfered with the wooden block and the fastening work became troublesome.

The object of the present invention is to solve these problems.

[0010]

The above objects can be attained by the invention of each claim.

According to the first aspect of the present invention, there is provided a metal plate fitting to be attached to the base frame for mounting a frame such as a window frame on the base frame having a groove-shaped cross section. By fitting into the groove of the base frame using the deformation, the base frame is held undetachably on the base frame.

As described in the prior art, the base frame for mounting the window frame is formed in a quadrangular shape by upper and lower horizontal frame members and left and right vertical frame members formed of a U-shaped cross-section channel. A groove of the material is opened inside the frame material.

In view of the above, the invention according to claim 2 includes, as a fitting for mounting the window frame, an insertion portion which is fitted deeply into the groove of the frame material, and a mounting portion to which the window frame is screwed. The insertion portion is provided with a contact portion that abuts against opposing inner surfaces of the frame member against elasticity.

According to a third aspect of the present invention, there is provided a metal fitting according to the second aspect of the present invention, wherein the mounting portion extends so as to cover an opening surface of the frame member. A pair of insertion portions extending so as to close the groove of the frame material are bent at end portions of the frame material located at both ends in the longitudinal direction of the frame material, and these insertion portions are elastically attached to opposing inner surfaces of the frame material. And a claw-shaped abutting portion that protrudes against the arm.

According to a fourth aspect of the present invention, in the second or third aspect, a portion of the surface of the mounting portion into which the screw is screwed is formed in a rough surface having a saw-toothed or embossed cross section.

[0016]

In each of the embodiments of the present invention, since the metal plate is attached to the base frame using the spring property of the metal plate, the metal plate can be largely elastically deformed, and as a result, the groove width dimension of the base frame. And can be mounted tightly without causing problems such as deformation of the base frame.

Further, since the metal fittings need only be pushed into the base frame by a worker or hammered with a hammer, the mounting work is simple. In addition, since the metal fittings can be firmly attached to the base frame using the spring properties of the metal plate, when the metal fittings are attached to the base frame in advance at the factory, there is no need to caulk the base frame as in the past. In this respect, the work efficiency can be improved.

Further, by using only the metal plate of the metal fitting, the fire resistance is excellent and the corrosion due to dew condensation or the like can be prevented or suppressed.

According to the present invention, when another member such as a shutter is fastened to the side plate of the frame member of the base frame with a screw, the screw is prevented from interfering with the metal fitting and the member such as the shutter is prevented. Can be easily installed.

According to the fourth aspect of the present invention, when the window frame is fastened to the bracket with the drill screw, the rough surface of the bracket prevents the tip of the drill screw from slipping. The tip can be accurately positioned and driven accurately and quickly.

Further, if the drill screw falls down at the beginning of the driving of the drill screw, the bit of the power driver may hit the window frame due to the momentum coming off the screw, and the window frame may be damaged. Since the screws can be prevented from falling, accidents that damage the window frame can be prevented.
