A pulling operation portion 6 is provided on the upper surface of the contact portion 4.
Is projected. The pulling operation part 6 is the bolt holding part 5.
After the bolt 3 held in the middle is driven into the roof material 2 partway, the contact portion 4 is moved in the direction G orthogonal to the direction A in which the bolt 3 is driven.
This is for pulling the bolt holder 5 away from the bolt 3 in this embodiment, and in the present embodiment, the pulling operation portion is formed in a rod shape that can be grasped by a hand, and is integrally formed on the upper surface of the contact portion 4. It is fixed. The shape of the pulling operation portion 6 is not limited to the rod shape, and the point is that the contacting portion 4 can be pulled in the direction G orthogonal to the driving direction A of the bolt 3, and its shape and its forming position. Is not particularly limited.

Next, the roof material 2 is fixed to the roof substrate 16 with the bolts 3.
An example of the case where the bolt 3 is fixed to the above will be described. First, as shown in FIG. 1, the contact portion 4 of the bolt holding jig 1 is placed on the upper surface of the mountain portion 14 into which the bolt 3 is to be inserted. At this time, since the abutting portion 4 is a cross-section U-shaped can be stably placed so as to straddle the crest 14 of the roofing material 2, easily position the abutment 4 against the roofing material 2 it can. And the shaft portion 3 of the bolt 3
When b is inserted into the bolt insertion hole 24 from above the bolt holding portion 5, the bolt 3 slides down from the bolt insertion hole 24 into the bolt insertion recess 11 of the abutting portion 4, and the tip of the bolt 3 reaches the peak portion 14.
The head 3a of the bolt 3 hits the surface of the
It stops in a state where it protrudes above the upper surface (state of FIG. 2).

By driving the bolt 3 vertically with an electric screwdriver or the like in this state, the driving angle of the bolt 3 is fixed, and while the bolt 3 is held by the bolt holding portion 5, the bolt 3 has an accurate angle. It will be driven in. At this time, since the bolt insertion hole 24 and the bolt insertion recess 11 are configured to be slightly larger than the outer diameter dimension D of the bolt 3, the bolt 3
Can be moved in the bolt insertion hole 24 and the bolt insertion recess 11 without being caught, and can be driven in smoothly. At this time, the abutting portion 4 is the mountain portion 14 of the roof material 2.
Since it is positioned by, it is not necessary to press the contact portion 4 by hand, and therefore, the work of inserting the bolt 3 can be performed easily.

Then, as shown in FIG. 3, the tip 3c of the bolt 3 is
When the bolts 3 have been driven to the extent that they are caught on the roof substrate 16, the work of inserting the bolts 3 is temporarily stopped, and the pulling operation portion 6 is grasped by hand and pulled in the direction G shown in FIGS. Is pulled rearward, and the bolt 3 pushes open the bolt pressing portion 10 by its reaction force and separates from the bolt holding portion 5 and the contact portion 4. At this time, as shown in FIG. 3, the height dimension h of the bolt holding portion 5 and the dimension H of the bolt 3 are such that, at the stage where the tip 3c of the bolt 3 is driven to the extent that the tip 3c of the bolt 3 is caught in the roof base 16, It is desirable that the dimensional relationship be set so that the portion 3a does not hit the upper surface 5a of the bolt holding portion 5. By setting in this way, even if the heat insulating layer of the roofing material 2 is a soft material such as soft urethane foam,
When the pulling operation portion 6 is pulled and the bolt holding portion 5 is removed from the bolt 3, it is possible to reliably prevent the bolt 3 from tilting. At this time, the head 3a of the bolt 3 is not in contact with the upper surface 5a of the bolt holder 5, so that the bolt holder 3 can be removed smoothly without resistance.

After removing the bolt holding portion 5 from the bolt 3 as described above, the bolt 3 is driven in the direction of the arrow in FIG. 7 until the head 3a of the bolt 3 hits the upper surface of the mountain portion 14 of the roofing material 2. . At this time, the tip 3c of the bolt 3 has already been driven into the roof substrate 16, so that the bolt 3 can be easily driven in the correct direction without tilting without the bolt holding jig 1.

The relationship between the height dimension h of the bolt holding portion 5 and the dimension H of the bolt 3 is not limited to the embodiment shown in FIG. 3. For example, the heat insulating layer of the roof material 2 is made of hard urethane foam. When the head 3a of the bolt 3 is not driven into the roof substrate 16, the bolt 3 may be removed when the head 3a of the bolt 3 is not driven. It can be prevented. Further, in order to smoothly remove the bolt holding portion 3 and surely drive the tip 3c of the bolt 3 into the roof substrate 16, the height dimension h of the bolt holding portion 5 is preferably about 50 to 60 cm, for example. In addition, when the tip 3c of the bolt 3 is driven to the extent that it is caught in the roof substrate 16, a gap of about several cm is created between the head 3a of the bolt 3 and the upper surface 5a of the bolt holding portion 5. Is desirable, but it is not limited to this value.

However, by holding the bolt 3 by using the bolt holding jig 1 of the present invention at the time of starting the driving as described above, it becomes unnecessary to hold the bolt 3 by hand as in the conventional case, and even an amateur can do it. Even if the surface of the roofing material 2 is composed of the metal plate 12 and the tip of the bolt 3 is slippery on the surface of the metal plate 12, it is possible to work safely and accurately without tilting the bolt 3. You will be able to enter at an angle. As a result, no skill is required to fix the roofing material 2 and the damage such as the diagonal driving is eliminated, so that the working efficiency is dramatically improved and the roofing material 2 is prevented from being scratched by re-bolting the bolt 3. As a result, the appearance can be kept good and there is no fear of rain leaks. In addition, since the contact portion 4, the bolt holding portion 5, the spring member 7, and the pulling operation portion 6 are integrated, the entire bolt holding jig 1 becomes light and the height is high such as a roof. It can be easily carried around, and the usability is improved. In particular, the abutment portion 4 can be easily moved by sliding on the mountain portion 14, so that the work of driving the bolt 3 into the mountain portion 1 of the roof material 2 can be performed.
It can be carried out smoothly at a plurality of four positions.

Further, the bolt holding portion 5 is a bolt receiving portion 9 fixed to the contact portion 4, and a rotatable bolt pressing portion elastically pressed toward the bolt receiving portion 9 by the spring member 7. Since it is composed of 10 and 10, the spring member 7 can stably hold the bolt 3 between the bolt receiving portion 9 and the bolt pressing portion 10, and the rattling of the bolt 3 does not occur when the bolt is driven. Since the opening width d of the side opening 8 between the bolt receiving portion 9 and the bolt pressing portion 10 is configured to be smaller than the outer diameter dimension D of the bolt 3 when the bolt pressing portion 10 is closed, the bolt striking Nyutoki bolt 3 is without fear exiting from the side opening 8, moreover, apertures direction E and bolt insertion of the bolt insertion recess 11 provided in the abutting portion 4 is in a state where the bolt holding portion 10 is closed Side of hole 24 Since the opening 8 is opened in a direction different from the opening direction C, the holding force of the bolt 3 is increased and the bolt 3 tilts laterally when the bolt 3 is driven in the closed state of the bolt retainer 10. Can be effectively prevented. On the other hand, when the bolt holding portion 5 is detached from the bolt 3, the side opening 8 is opened greatly at a small opening angle of the bolt pressing portion 10, so that the bolt 3 can be detached smoothly, and the bolt 3 is removed. Can be done easily.

In the above embodiment, the abutting portion 4 is composed of a single plate member having an inverted U -shaped cross section, which is placed on the mountain portion 14 of the roof material 2, but the mountain portion 14 has a width dimension of It may vary depending on the roof material 2, and it is desirable that the abutting portion 4 has a structure capable of expanding and contracting in consideration of this. For example, the contact portion 4 is composed of two divided plate materials, and by connecting the two plate materials so as to be movable in the horizontal direction, the contact portion 4 is expanded and contracted according to the width dimension of the mountain portion 14. This makes it possible to support any type of roofing material 2.

Further, as the roofing material 2, the roofing material 2 in which a plurality of peaks 14 are provided on the surface is exemplified, but the kind of the roofing material 2 is not limited to this, and the surface is flat. It is also applicable to the roof material 2. In this case, it is possible to deal with this by forming the contact portion 4 into a flat plate shape.

The jig 1 for holding bolts according to the present invention comprises a roof material 2
It is also widely applicable to other building structures such as wall panels. That is, when the contact portion 4 is arranged along the vertical wall surface,
The bolt holding portion 10 of the bolt holding portion 5 can be opened and closed in the vertical direction, and the bolt 3 can be held in the horizontal direction, so that the wall panel can be fixed. Of course, the present invention is not limited to holding the bolt 3 and can be widely applied to various fasteners such as nails and screws.
