It is also fixed to the mounting plate 81 by means of fixing means such as screws, nuts or welding. A running wheel 85 is attached to the lower surface of the lower plate piece 84 , and the frame 8 is movable by the running wheel 85 .

As indicated by the dotted line in FIG. 1(A), the reinforced enclosure A is composed of a plurality of folded plate-type building boards 10. As shown in FIG. The building board 10 is formed with rising side portions 102, 102 on both sides in the width direction of the main plate 101, a top portion 103 is formed on the upper end of the rising side portion 102, and a bottom portion 104 is formed on the top portion 103 on one side. is formed, and an upper rise portion 105 is formed on the top portion 103 on the other side [see FIGS. 3(C) and 6(H)].

The lower portion 104 has a lower arcuate piece 104b that bulges outward (as seen from the main plate 101 side) in a substantially semicircular shape from the upper end of the vertical rising portion 104a. A lower top piece 104c is formed from the upper end of the arc-shaped piece 104b, and a folded end edge 104d having a cross section is formed on the lower surface side from the outer end of the lower top piece 104c. The folded end edge 104d is formed in a flat C shape on the back side of the lower arc-shaped piece 104b, or formed in a substantially close contact state.

The upper rib portion 105 is formed with an upper arc-shaped piece 105b that protrudes in a substantially semicircular shape toward the main plate 101 from the upper end of the vertical rising portion 105a on the other side. The upper arc-shaped piece 105b is formed in an arc-shape large enough to inscribe the lower arc-shaped piece 104b of the lower portion 104, and the upper top piece extends outward from the upper end of the upper arc-shaped piece 105b. 105c is formed.

The upper top piece 105c has a substantially flat surface like the lower arcuate piece 104b of the lower portion 104. As shown in FIG. A fastening piece 105d having a cross section is formed on the lower side of the outer end of the upper top piece 105c. The tightening piece 105d is a portion that covers the gap between the lower top piece 104c and the upper top piece 105c and blocks rainwater from the outside while being fastened and connected.

By joining the rising sides 102, 102 of the adjacent building boards 10, 10 with a lower rise portion 104 and an upper rise portion 105, it is possible to form a rough structure. A shaped tightening portion 106 is formed. That is, the lower part 104 and the upper part 105 are connected to each other. In the stiffening portion 106, the vertical rising portion 104a of the lower stretching portion 104 and the vertical rising portion 105a of the upper stretching portion 105 overlap each other in a substantially closely contact state in the vertical direction, and the lower arc-shaped piece 104b and the lower arc-shaped piece 104b overlap each other. The upper arcuate piece 105b overlaps, and the lower top piece 104c and the upper top piece 105c overlap.

At this time, each part of the lower part 104 and the upper part 105 is in close contact or substantially close contact. As described above, the fastening piece 105d of the upper rake portion 105 covers the gap between the lower top piece 104c and the upper top piece 105c to keep out the rain. The lower arc-shaped piece 104b and the lower top piece 104c are sandwiched between the clamping piece 105d, the upper arc-shaped piece 105b and the upper top piece 105c so as to be wrapped around the side arc-shaped piece 104b and the lower top piece 104c. It constitutes.

Next, a construction method for dismantling the fastening portion 106 of the fastening envelope A by using the fastening dismantling machine of the present invention will be described with reference to FIGS. 4 to 7. FIG. Before that, there is a manual setup. That is, the upper stretched portion 105 is moved from the stretched state to the open state by the tool T at the longitudinal direction end portion of the upper stretched portion 105 composed of the lower stretched portion 104 and the upper stretched portion 105 of the stretched portion 106 . While widening the ends, an upward deformed portion H is formed so as to be substantially parallel to the top portion 103 [see FIGS. 5(A) and 5(B)]. As a result, the deformed state of the stiffening portion 106 shown in FIGS.

Then, as shown in FIGS. 4(A) to 4(D) , the widening portion 41 of the quickening jig 4 of the fastening disassembling machine is set to the gap between the lower and upper raising portions 104 and 105, specifically The tightening portion 106 is installed between the folded end edge 104d and the tightening piece 105d, which is the place where the upper deformation portion H is formed by the tool T, and a (substantially truncated cone-shaped) receiving roll 1, A (substantially disc-shaped) pressing roll 3 is placed on the top of the mountain-shaped portion 106 of the tightening envelope A. As shown in FIG. At this time, the pressure roll 3 is kept in a state in which the gap between the pressure roll 3 and the receiving roll 1 is opened by the handle 7 .

As shown in FIGS. 5(C) and 5(D), the receiving roll 1 is arranged on the outer side of the stiffening portion 106 which is the upper deformed portion H, the handle 7 is tightened, and the pressure roll 3 on the side of the receiving roll 1 is placed. move in the direction. That is, the pressing roll 3 is arranged inside the deformation side 106 b so that the tightening piece 105 d of the tightening portion 106 is in contact with the upper surface of the pressing roll 3 . The positional relationship among the receiving roll 1, the pressing roll 3, and the upper deforming portion H at this time is shown in FIG. 6(E). The upper surface of the pressing roll 3 is in contact with the clamping piece 105d.

Next, the rake dismantling machine moves while the rake jig 4 bites between the folded end edge 104d of the lower rake portion 104 and the tightening piece 105d of the upper rake portion 105 [FIG. , see FIGS. 5(C) and (D)]. A gap formed between the folded end edge 104d of the lower raised portion 104 and the tightening piece 105d of the upper raised portion 105 by the raising jig 4 is inserted into the lower corner portion of the outer peripheral side surface 31a of the pressing roll 3. By approaching the folded edge 104d of the lower part 104 and starting to press it, the width of the gap is further expanded.

Specifically, as described above, the tightening piece 105d of the fast tightening portion 106 is grounded on the upper surface of the press roll 3 when the fast tightening and disassembling machine is installed, so that the entire press roll 3 is lowered. It can be made to bite between the folded edge 104d of the portion 104 and the tightening piece 105d of the upper rise portion 105, thereby pushing the tightening piece 105d upward (see FIG. 6(E)).

Further, the upper top piece 105c is curved upward by pushing up the tightening piece 105d, thereby expanding the gap between the lower top piece 104c and the upper top piece 105c. [See FIG. 6(F)]. At this time, the upper apex piece 105c is curved upward, and a deformed portion in which the gap between the lower apex piece 104c and the upper apex piece 105c is enlarged is referred to as an upward curved deformed portion J.

Through such a process, after passing the rake dismantling machine, between the folded end edge 104d of the lower rake part 104 and the tightening piece 105d of the upper rake part 105, between the lower top piece 104c and the above-mentioned A gap is formed between the top piece 105c and the tightening piece 105d, which is the end of the top portion, and the top piece 105c, which is the top portion, is deformed to continuously form the curved deformed portion J. [See FIG. 6(F)].

In the dismantling method described above, the upper stretched side portion 105 is deformed, whereas the lower stretched side portion 104 is substantially not deformed. When separating the upper and lower treatment, it is possible to easily separate the upper and lower treatment by simply lifting the upper treatment as it is or by slightly inverting the upper treatment. It is possible to dismantle more easily than the conventional dismantling method that deforms.
