Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a sheet cutting jig and a sheet cutting method used for cutting a sheet attached to a panel.

[0002]

2. Description of the Related Art Panel construction methods are known in which floors, walls, roofs and the like of houses are constructed using panels. In the panel construction method, a panel is manufactured in advance at a manufacturing place such as a factory, and the panel is transported to a construction site to perform construction. The panel has, for example, a structure in which vertical and horizontal auxiliary members are arranged inside a frame constructed by assembling vertical and horizontal frame materials, and a face material is attached to at least one side surface of the frame. I have.

[0003] Of the above-mentioned panels, a panel to be an outer wall of a house is provided on at least one side surface of a panel frame as disclosed in, for example, the prior art of JP-A-7-197593. There is a case where a moisture-permeable waterproof sheet is previously arranged on an upper surface of a surface material (for example, a surface material attached to a surface serving as an outer wall) at a manufacturing place such as a factory. The moisture-permeable waterproof sheet is a well-known sheet member that can transmit moisture and water vapor but does not allow rain and wind to pass therethrough, and examples thereof include a Tyvek sheet. In this way, for what is to be arranged on the panel during construction, if it is arranged on the panel in advance at the manufacturing stage,
It is possible to save labor and shorten the construction period at the construction site. In general, as disclosed in the prior art of the above-mentioned publication, the moisture-permeable waterproof sheet is arranged, and a heat insulating material, an exterior material and the like are arranged on the panel.

As disclosed in the above publication,
Panels to be arranged adjacent to each other at the time of construction may be joined in advance at the manufacturing stage to form one connected panel. Also in this case, a moisture-permeable waterproof sheet is arranged on the upper surface of the connection panel.

[0005]

On the other hand, there are cases where a house is provided with a shed adjacent to the outer wall of the house. In this case, the shed is joined to a panel that will be the outer wall of the house. And, as described above, in the panel, in the manufacturing stage, the moisture-permeable waterproof sheet is integrally disposed on the surface of the panel. However, if the moisture-permeable waterproof sheet is arranged as described above, the underpass is joined. When doing, since the moisture-permeable waterproof sheet will be interposed between the frame of the panel and the frame of the shed, the part that joins the shed and the part that will be hidden by the shed It is necessary to cut the above-mentioned moisture-permeable waterproof sheet.

Heretofore, such a work of cutting the moisture-permeable waterproof sheet has been performed at a construction site. Therefore, the work load on the site increases, and it is difficult to shorten the construction period. Further, even if the above-mentioned cut work of the moisture-permeable waterproof sheet is performed at the panel manufacturing stage, for example, if the cut work is performed manually, not only the work becomes complicated and the work load is increased, but also the cut precision control is sufficiently performed. It will be difficult to do.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to cut a moisture-permeable waterproof sheet to be disposed on a panel in advance according to the shape of a shed, and to control the cutting accuracy easily. It is an object to provide a jig for use and a sheet cutting method.

Further, if the sheet cutting jig 10 according to the first aspect is arranged one at a time on at least two side edges of the panel, each guide means (1) is provided.
The tape member 13a of 3) can be extended to cross the panel. Therefore, it is possible to easily cut the sheet along the tape member 13a arranged in an intersecting manner while changing the cutting angle in the middle. For example, it is possible to cut the sheet into a polygonal line shape having at least one vertex. it can. Further, by combining the operation of moving the sheet cutting jig 10 in parallel along the side edge, the sheet cutting jig 10 can be cut in a polygonal line shape having at least two or more vertices. In the above case, the guide means (13) of each of the sheet cutting jigs 10 is independently provided with the tape member 13a at an arbitrary angle or a predetermined angle.
Can be extended, so that the degree of freedom of the broken line shape in which the tape member 13a can be extended can be further increased, and the sheet can be cut into a more complicated shape.

According to the above construction, for example, at the stage of manufacturing a panel to be an outer wall having a shed, a well-known moisture-permeable waterproof sheet to be provided on the panel is cut in advance according to the shape of the shed. Since there is no need to cut the moisture-permeable waterproof sheet according to the shape of the shed at the construction site, labor saving of the construction work at the site and shortening of the construction period can be achieved.
