Abstract

PURPOSE:To fit only a nut to a tool for fastening, by fixing a washer at a bolt and fitting the washer to a main member. CONSTITUTION:When external wall panels 12, 13 are attached for instance, the bolt hole 24 of the upper fitting metal block 22 of the lower side external wall panel 13 is positioned to correspond to the fixing slit 11 of the bracket 3. Next, in this condition, the bolt 25 is inserted into the bolt hole 24 from the back side of the fitting metal block 22 and the front end thereof is protruded out of the slit 11 and the nut 29 is screwed for fastening. In this time, the bolt 25 is fastened so that the horizontal fitting part 28 of the upper end of the washer 27 comes in contact with the upper end face of the vertical part 23. And further, the bolt hole 21 at the lower end of the upper side external wall panel 12 is forced to meet the upper part of the same slit 19 and the same bolt 25 is inserted front the back side of the plate 19 and fastened with the nut 29. In this case, the fitting part 28 of the washer 27 is fitted to the upper end of the plate 19 and it prevents the bolt from rotating.

[Prior Art] When fixing parts with bolts and nuts, usually one of the nuts or bolt heads is held with a tool such as a spanner to prevent it from turning, and the other bolt or nut is tightened with another tool. It needs to rotate. However, this method has the disadvantage that both hands must be used at all times, resulting in poor work efficiency.Especially when tightening on both sides of a large panel, the work cannot be done by one person because the hands cannot reach the back side. It's inconvenient. Therefore, in such a case, conventionally, a nut is welded to the back side of a bolt hole formed in advance.

[Problem to be Solved by the Invention] As mentioned above, by welding the back nut, it is possible to hold and tighten only the bolt with a tool, but this is difficult to do with metal materials that will be painted later. In such a case, there is an inconvenience that the paint sticks to the female threaded part of the nut, making it difficult to tighten the bolt. SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a device that can prevent bolts from rotating without welding nuts in advance.

In the above configuration, first, the bolt holes 24 of the upper mounting bracket 22 of the lower exterior wall panel 13 suspended by a crane are aligned with the fixing slits 11 of the support bracket 3, and in this state, the mounting bracket 22 is The bolt 25 is inserted into the bolt hole 24 from the back side of the bolt 25, and the tip thereof is made to protrude from the slit 11, and the nut 29 is screwed and tightened. At this time, the bolt 25 is installed so that the horizontal engaging part 28 at the upper end of the washer plate 27 comes into contact with the upper end surface of the vertical part 23, so that the bolt 25 is held without rotating. , it is sufficient to engage only the nut 29 with a tool and rotate it. At this time, the outer wall panel 13 is shifted vertically and horizontally within the range of the elongated hole 21 and the slit 11 to determine its vertical position, and is finally tightened and fixed. Furthermore, align the bolt hole 21 at the lower end of the upper side outer wall panel 12 with the upper side of the same slit 11, insert the same bolt 25 from the back side of the plate 19, and screw it in with the nut 29 in the same manner and tighten. Fix it. In this case, the engaging portion 28 of the washer plate 27 engages with the upper end of the plate 19 to prevent the joint rotation. The lower end side of the lower exterior wall panel 13 in the figure is also attached in the same manner as the upper exterior wall panel 12 in this figure. Furthermore, an outer wall panel is similarly attached to the left side of each of the outer wall panels 12 and 13 in FIG. 1, and is fixed using the slit 11 on the left side of the support fitting 3 in the figure. At this time, the central gauge slit 9 serves as a gauge for the joint width between the two, and the left and right positions of the outer wall panels 12 and 13 are adjusted to match the width of the slit 9.
