Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting fitting adjusting jig used for fitting fittings such as window sashes to a building frame at a construction site.

[0002]

2. Description of the Related Art For example, when a window sash is attached to an opening frame of a building frame at a construction site, conventionally, a wooden wedge member 34 is used to adjust the position of the window sash 30 as shown in FIG. That is, the sash side receiving plate 32, the opening frame side receiving plate 33, and the wedge member 34 are interposed between the window sash 30 and the opening frame 31a of the building frame 31, and the wedge member 34 is hammered in to open the sash side receiving plate 32. The height position of the window sash 30 with respect to the frame 31a is adjusted.

[0003]

However, the attachment adjustment of fittings using the wooden wedge member 34 as described above has the following problems. A large amount of wooden wedges 34 and receivers 32 and 33 are required,
A great deal of effort is required for transportation to the construction site. Since the wedge material 34 and the like lack durability and are consumed, a large amount is consumed and disposed of, resulting in an increase in cost. It takes a considerable amount of time to set the thickness of the wedge material 34 and the like. It is also troublesome to remove and collect the wedges 34 and the like used as described above after the fittings have been attached. In the mounting work as described above, the range of the adjustment width or the adjustment height by the wedge member 34 or the like is narrow, and therefore it is often necessary to adjust to a position outside the range, and each time, the corresponding wedge member 34 is replaced. It has to be done, and the adjustment work becomes more and more complicated.

An object of the present invention is to provide an adjusting jig for attaching fittings which enables easy and accurate attachment and adjustment of fittings to a building frame.

[0005]

The fittings adjusting jig according to claim 1 of the present invention is one in which a bottom base and a support are connected by a pantograph type screw jack mechanism. The screw jack mechanism includes a pantograph mechanism, a main shaft vertical adjustment bolt, and a sub shaft fine adjustment bolt. In the pantograph mechanism, a total of eight rotatable pivoting arms are provided in pairs on both sides of the bottom board stand and the support stand, spaced apart from each other in the longitudinal direction, and four panning arms are provided at one end side in the longitudinal direction. One in which the tips of the rotating arms are rotatably connected by a first link pin, and the tips of four rotating arms located on the other end side are rotatably connected by a second link pin. Is. The main shaft vertical adjustment bolt is inserted into a member with a hole provided in the first link pin, the tip of which is engaged by a stopper, and is screwed into a female screw member provided in the second link pin. is there. The counter shaft fine adjustment bolt is rotatably connected to one of the bottom board base and the support base, penetrates the other base, and has a nut screwed on the outside of the other base.

The bottom base and the support base are groove-shaped bases whose opening sides are opposed to each other, and a plurality of notches for allowing the first and second link pins to escape are provided on both flanges of the base base and the support base. May be.

[0007]

According to the adjusting jig having this structure, when the nut of the auxiliary shaft fine adjustment bolt is not in contact with the bottom base or the support base, the main shaft vertical adjustment bolt is turned to rotate the first and second links of the pantograph mechanism. The distance between the pins is changed, and the distance is changed in a state where the bottom board and the support are parallel to each other. At this time, the stopper of the spindle vertical adjustment bolt is the first
It is in a state of being engaged with the member with the hole of the link pin. When the nut of the counter shaft fine adjustment bolt is in contact with the base plate or support base, rotate the main shaft vertical adjustment bolt in the direction to expand both bases, and the gap between the base plate and support base at the nut contact part Being restrained, the bottom base and the support base gradually widen the opening angle so that the end opposite to the nut is opened. At this time, since the stopper is separated from the member having the hole of the first link pin, the angle change as described above becomes possible. You can also change the opening angle of both stands by turning the nut. When adjusting by turning the nut, it is better than when adjusting by turning the spindle vertical adjustment bolt.
The amount of change in the distance between the two units is small in terms of the turning angle ratio, making fine adjustment easy.

When this adjusting jig is used for attaching fittings, it is operated in the following procedure. First, the gap between the bottom base and the support is roughly adjusted according to the gap between the building frame to which the fitting is to be attached and the fitting, and this jig is inserted in the gap. Then, the nut of the main shaft vertical adjustment bolt or the sub shaft fine adjustment bolt of the screw jack mechanism is rotated to expand / contract the pantograph mechanism to adjust the distance between the bottom plate and the support. This makes it possible to easily adjust the position of the fitting with respect to the building frame. Further, by adjusting the opening angle between the bottom base and the support base, it is possible to stably install even if the fitting arrangement surface of the building frame is inclined.

When the bottom board and the support are grooved and the notches are provided on both flanges of the two boards as described above, the notches allow the first and second link pins to respectively escape. Therefore, at the time of narrowing, the minimum distance between the bottom base and the support base can be sufficiently narrowed, and it can be used even when the gap between the building frame and the fitting is small.
