2. Description of the Related Art In recent years, an opening at a corner of a building is often made of glass.
The glass plate is generally held on a sash such as an aluminum sash.

[0003] By the way, as for arranging a sash at an opening in a corner of a building, the operation requires skill and the like, and at present, it cannot be performed quickly.

More specifically, as shown in FIG. 5, a sash is provided at an opening in a corner of a building in such a state that an end of a frame member 1 as a sash member constituting the sash is in a so-called straight state. It will be connected after being combined.

[0005] In this case, the break line at the end of the form material 1 is set so as to be 45 degrees with respect to the axis of the form material 1. It is necessary to prevent the grooves 2 of each of the form members 1 facing each other from shifting from each other.

In particular, although not shown, when the opening is formed in the concrete frame, a wedge is interposed between the form member 1 and the concrete frame, and the wedge is appropriately advanced and retracted to form the frame. It is necessary to adjust the position of the material 1 up and down and back and forth, and thereafter perform temporary fixing by using, for example, welding, and then finally fix it to the opening of the building with mortar or the like. .

After the sash is fixed to the opening in the groove 2, a glass plate G is provided with an appropriate sealing member (not shown).
It is housed under the interposition of.

However, in consideration of the above-mentioned work,
It is not easy to keep the form materials 1 approaching from both directions in a state where the grooves 2 are aligned by the time of so-called temporary fixing by use of welding or the like. And this cannot be done quickly.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to bring an end portion of a form member, which is a sash member constituting a sash such as an aluminum sash, into close proximity from both directions. It is an object of the present invention to provide a connection fitting which is optimal for performing the connection work reliably and quickly when the connection fittings are connected in a mating state.

[0010]

In order to achieve the above-mentioned object, the structure of the present invention is applied by pressing both sides of a rod-shaped main body into a screw hole exposed at an end of a frame material as a sash member. In a connection fitting formed so as to connect form materials approaching from both directions, a main body is engaged with a projection part which fits into a split groove formed in a screw hole on the outer periphery on both sides thereof, and is engaged with an inner wall of the screw hole. And a claw portion to be formed.

More specifically, it is assumed that the claw portion is disposed on the side opposite to the projection with the main body therebetween.

If necessary, it is assumed that the main body is bent at an appropriate angle at the center thereof.

[0013]

Therefore, one side of the main body is press-fitted into a screw hole exposed at an end of a frame material as one sash member.
By press-fitting the other side of the main body into a screw hole exposed at the end of the other facing form member, the connection of the end of the form member approached from both directions is realized.

When both sides of the main body are press-fitted into the respective screw holes, the protrusions formed on the main body fit into the split grooves formed in the screw holes. When formed on the same line to be extended, the form members are connected coaxially without being rotated.

Further, when the both sides of the main body are press-fitted into the respective screw holes, the claws formed on the main body are engaged with the inner walls of the screw holes. Omission is prevented.

If the frame members are connected at an appropriate angle, the main body is bent at the center thereof so as to coincide with the intersection angle formed by the axes of the frame members on both sides. Thus, a desired connection state is realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on the illustrated embodiment. As shown in FIG. 1, a connection fitting 10 according to one embodiment of the present invention has a round bar-shaped main body. A protrusion 12 and a claw 13 are provided on both sides of the main body 11, respectively.

In the illustrated example, the connection fitting 10 cuts the end of the form material 1 approaching from both sides in the horizontal direction, that is, the upper side in the figure and the left side in the figure, at 45 degrees. It is set so as to be most suitable for use in a case where the end portions of the form materials 1 approaching from both directions are connected at a right angle.

The form member 1 is a sash member that constitutes a sash such as an aluminum sash, and is made of aluminum even in the illustrated example, and becomes a shaft core as shown in FIG. At the center, there is a groove 2 opening to the upper surface, and the glass plate G is housed in the groove 2 with the interposition of a sealing member (not shown).

Therefore, in the illustrated example, the side ends of the glass plates G housed in the grooves 2 of the respective frame members 1 are connected at right angles (see FIG. 5).

The form member 1 has a pair of left and right screw holes 3 disposed on the back side of the form member 1 so as to sandwich the groove 2. Says that a screw (not shown) is screwed into this,
In the present invention, both sides of the main body 11 are pressed into the screw holes 3.

The screw hole 3 is generally provided with a split groove 3a so that the screw can be easily screwed.

Therefore, the main body 11 is in the illustrated example, and is formed by being bent at a right angle at the center thereof so as to be suitable for use when the ends of the form material 1 are connected at a right angle. It is stated that a steel material is selected in view of forming the claw portion 13.

In addition, the main body 11 is set so that the thickness of both sides thereof is slightly smaller than the inner diameter of the screw hole 3 in the form material 1. And as long as the claw portion 13 is provided.

However, preferably, the claw portion 13 is attached to the main body 1.
The length is set to such a length as to be able to be arranged in the axial direction on both sides of the device.

The projections 12 are set so as to fit into the split grooves 3a in the screw holes 3 when both sides of the main body 11 are pressed into the screw holes 3 (see FIG. 2). It is arranged on the outer periphery of.

However, the split groove 3a formed in the screw hole 3 is open at the so-called bottom side of the formwork material 1 which is the lower side in the figure.
In the illustrated example, the main body 11 is provided on the outer periphery on the bottom side which is the lower side in the figures on both sides (see FIG. 2).

It is sufficient that the projections 12 are provided at one position on both sides of the main body 11 at so-called end portions.
It suffices that the length has sufficient dimensions to have self-supporting properties and to function as a so-called guide.

When both sides of the main body 11 are press-fitted into the screw holes 3, the claw portions 13 are inserted into the inner wall 3 of the screw holes 3.
b is set so as to engage with the so-called biting state, and on both sides of the main body 11, the so-called opposite side of the protrusion 12, that is, the main body 1
Are disposed on the opposite side (upper side in FIG. 2).

The shape of the claw portion 13 can be freely set as long as the above-mentioned engagement is possible. In the illustrated example, the claw portion 13 is formed in a triangular pyramid shape. May be formed so as to partially cut and raise the outer periphery.

The greater the number of the claw portions 13, the more effective the engagement of the screw holes 3 with the inner wall 3b. However, if the number of the claw portions 13 is too large, press-fitting into the screw holes 3 on both sides of the main body 11 is performed. Is not preferred because it is not easy.

Therefore, in the illustrated example, the claw portion 13 is
1 are provided in two stages, which are front and rear along the axial direction on both sides.

The front claw 13 and the rear claw 13
Is preferably set such that the disposition directions do not match and are eccentric.

That is, suppose that the front claw portion 13 and the rear claw portion 1 are provided.
When the disposing directions of the main body 11 are the same, when the both sides of the main body 11 are pressed into the screw holes 3,
However, the rear claw portion 13 is disposed at a so-called scratched portion, which causes a problem that the engagement effect is reduced.

Therefore, when the claw portions 13 are provided in the front and rear two stages, it is important that the positions of the front claw portions 13 and the rear claw portions 13 are eccentric to each other. Although the center position can be selected, in the illustrated example, it is assumed that the rear claw portion 13 is disposed at a position deviated by about 30 degrees from the front claw portion 13.

However, even if the eccentric position can be freely selected, if the eccentric angle of the rear claw 13 with respect to the front claw 13 is too large, for example, 90 degrees, the form material made of aluminum material is used. Screw holes 3 in 1 are split grooves 3a
Is unfavorable because the screw hole 3 is easily broken or the like.

According to the connection fitting 10 according to this embodiment formed as described above, one side of the main body 11 is press-fitted into the screw hole 3 exposed at the end of the form member 1 as a sash member, and the main body 11 is pressed. Is press-fitted into a screw hole 3 exposed at an end of a neighboring formwork 1 so that the other side of the formwork 1 is opposed to the formwork 1 so as to be approached from so-called both directions, which is a perpendicular direction.
Communicate connection is realized.

At this time, since the projection 12 formed on the main body 11 is fitted into the split groove 3a formed on the screw hole 3, the projection 12 extends in the axial direction of the main body 11 on the outer periphery on both sides of the main body 11. By being formed on the same line, the form members 1 are connected coaxially without being rotated.

Accordingly, when the frame members 1 are brought close to each other and their ends are connected to each other, the grooves 2 formed in the respective frame members 1 can be easily matched.

Further, since the claw portion 13 formed on the main body 11 is engaged with the inner wall 3b of the screw hole 3, the main body 11 pressed into each screw hole 3 is prevented from being pulled out from each of the screw holes 3 on both sides. .

Accordingly, it is possible to easily maintain the matching state of the grooves 2 in the form members 1 whose ends are approached from both directions, and the form materials 1 connected in a predetermined manner before full-scale fixing are performed. This will facilitate so-called temporary fixing work.

When the frame members 1 are connected to each other at an appropriate angle, the main body 11 is adjusted so that the axes of the frame members 1 on both sides coincide with the intersection angle. By setting to be bent at the center, a desired connection state can be realized.

FIGS. 3 and 4 show a connection fitting 10 according to another embodiment of the present invention. In this embodiment, the connection fitting 10 allows the connection fitting 10 to approach from both the horizontal and vertical directions. Form materials 1 are connected at right angles,
It is set to be suitable for use when a gate or frame type sash is to be assembled.

To explain a little, the connection fitting 10 according to this embodiment also has a main body 11 bent at a right angle similarly to the above-described embodiment, and the projections are provided on both sides of the main body 11, respectively. 12 and a claw portion 13 are provided.

Then, the main body 11, the projection 12, and the claw 1
3 is the same as that of the embodiment described above. In particular, the claw portions 13
, That is, on the opposite side of the projection 12 with respect to the main body 1.

However, in the illustrated example, when the projection 11 and the claw 13 make the main body 11 so-called flat,
It is set so as to be positioned on one so-called side surface.

In the case of this embodiment, when a gate-shaped or frame-shaped sash is formed using the formwork material 1, the connection portion is conventionally connected by using a screw. There is an advantage that it is possible to easily assemble a gate type or a frame type sash by using the sash.

As described above, in any case, the main body 11 constituting the connection fitting 10 is formed so as to be suitable for use when the form material 1 approaching from both directions is connected at right angles on a plane or an elevation. It is said that it is bent at a right angle,
Instead, the intersection of the axes of the form material 1 in both directions is suitable for use when the form material 1 approaching from both directions is connected at an angle other than a right angle on a plane or an elevation. The main body may be bent at the center so as to coincide with the corner.

Further, instead of the main body 11 being bent at an appropriate angle at the center thereof, the connecting fitting 10 is formed in a straight shape by forming the main body 11 in a straight shape, and You may make it suitable for use when connecting one to another linearly.

[0050]

As described above, according to the present invention, both ends of the main body are press-fitted into the screw holes formed in the form material approaching from both directions, and the end of the form material is removed. It is easily possible to make the connection in a predetermined mating state, and is therefore necessary for the work, especially when arranging a sash for arranging a glass plate at a right angle in an opening in a corner of a building. There is an advantage that this can be performed reliably and quickly without requiring the above caution and skill.

Further, according to the present invention, since the structure of the connection fitting itself is simple, there is an advantage that adoption of the connection fitting does not cause a large burden in terms of cost.
