JP7484678B2 - Main roof panel assembly jig - Google Patents

Description

The invention disclosed in this application relates to a jig for pre-processing in a factory a purlin sheathing panel for a sloped roof, in which the purlin and sheathing boards are pre-assembled together.

In the construction of prefabricated buildings with sloping roofs, a method is often adopted in which a roof panel prefabricated in a factory is placed on top of the rafters, and then the necessary waterproofing treatment is applied before the roofing material is laid. Examples of such roof panels include "rafter roofing panels" which are made by joining a roofing board onto multiple rafters (members that are erected in the direction of the slope at appropriate intervals in the horizontal direction).
- "Main roof sheathing panel" made by joining sheathing boards onto multiple main roofs (components erected horizontally at appropriate intervals in the direction of the gradient)
etc.

When this type of roof panel is prefabricated in a factory, a worker places the rafters or purlins in the designated positions on a suitable workbench, then places the sheathing boards on top and joins them with nails or screws. However, in buildings with hipped or gambrel roof styles, or buildings with complex roof surfaces such as curved roofs, the planar shape of the roof panels that contact the corners and valleys of the roof will be a triangle, trapezoid, parallelogram, etc. The dimensions of each side and the angle of the hypotenuse of such non-rectangular roof panels are calculated for each building according to the roof slope, so an assembly jig is required to cut these components to the exact dimensions and shape and join them together in the correct positional relationship.

Patent Document 1 discloses a jig for processing roof panels (rafter sheathing panels) for wooden buildings, which includes a platform with multiple rows of insertion holes, various receivers and tip receivers that can be inserted into the insertion holes of the platform, and sheathing board restraining devices that can be fitted and removed from the receivers and tip receivers. The various receivers and tip receivers are appropriately arranged in the rows of insertion holes provided on the platform according to the arrangement of columnar members such as rafters and corner posts of the roof panel to be produced, and the columnar members such as rafters and corner posts are fitted into the receivers and tip receivers, allowing each columnar member to be correctly positioned on the platform. With each columnar member positioned on the flat plate, they are connected by nailing or the like, and a sheathing board is attached on top of them, allowing the desired roof panel to be produced.

JP 2005-001017 A

If the roof slope is different, the angle of the corner valley line relative to the eaves line (horizontal reference line) will change. Also, in the case of a purlin roof panel, in which a roof board is joined onto the purlin, the spacing of the purlins may also change depending on the roof slope.

However, the jig disclosed in Patent Document 1 can only accommodate one type of roof slope because the angle between the row of insertion holes for the corner or valley studs and the row of insertion holes parallel to the eaves line is constant, and the spacing between the rows of insertion holes for the rafters is also constant. For buildings with different roof slopes, a different jig with a different angle for the corner and valley line and spacing for the support materials (rafters or purlins) must be used, but because the planar size of the jig itself is large, preparing multiple types of jigs would require a large amount of space, which would be uneconomical.

The invention disclosed in this application was made in consideration of these circumstances, and aims to provide a jig for assembling roof rafter panels that can assemble roof rafter panels of various shapes to accommodate multiple types of roof slopes.

In order to achieve the above-mentioned object, the jig for assembling a purlin roof panel of the invention disclosed in this application comprises a base frame provided with an eaves guide for positioning the eaves line of the purlin roof panel along one edge, and a plurality of purlin support bases that are mounted on the base frame with their material length direction parallel to the eaves line and move in a direction perpendicular to the eaves line, the base frame being provided with a plurality of rails that extend in a direction perpendicular to the eaves line and movably support the purlin support base, and a plurality of purlin positioning guides that extend parallel to the rails and position the purlin support base at a predetermined position according to the roof slope, the purlin support base is supported on the rails via running wheels attached to its underside, and both side edges of the purlin support base are ... both side edges of the purlin support base are provided with a plurality of rails that extend in a direction perpendicular to the eaves line and movably support the purlin support base, and both side edges of the purlin support base are provided with a plurality of rails that extend in a direction perpendicular to the eaves line and movably support the purlin support base, and both side edges of the purlin support base are provided with a plurality of rails that extend in a direction perpendicular to the eaves line and movably support the purlin support base, and both side edges of the purlin support base are provided with a plurality of rails that extend in a direction perpendicular to the eaves line and movably support the purlin support base, and The basic configuration is as follows: multiple sets of purlin support pieces are erected at opposing intervals equivalent to the width of the purlin material, and where the purlin positioning guide and the purlin support base overlap, a purlin positioning means for arranging the multiple purlin support bases at intervals according to the roof slope is provided so as to accommodate multiple types of roof slopes, and at the middle part of the purlin support base in the material length direction, a corner valley positioning means for determining the corner valley line of the purlin sheathing panel with the purlin support base positioned at an interval according to the roof slope is provided so as to accommodate multiple types of panel shapes, and the purlin sheathing panel is formed by overlapping and joining the sheathing boards on top of the purlin positioned on the purlin support base via the purlin positioning means and the corner valley positioning means.

Furthermore, the specific configuration of the purlin positioning means includes a plurality of purlin positioning pin insertion holes formed in the purlin positioning guide, a purlin positioning pin insertion plate attached to the purlin support base, a positioning pin insertion hole formed in the purlin positioning pin insertion plate, and a positioning pin that is removably inserted into the purlin positioning pin insertion hole and the positioning pin insertion hole, and the purlin positioning pin insertion holes are formed in a row at a predetermined interval set according to the roof slope in a direction perpendicular to the eaves line, and the insertion hole rows are formed in multiple rows corresponding to multiple types of roof slopes, while the purlin positioning pin insertion plate has a plurality of positioning pin insertion holes formed in it that match the multiple rows of insertion holes.

In the above-mentioned configuration, it is more preferable that the hole diameter of the main house positioning pin insertion hole formed in the main house positioning guide, the hole diameter of the positioning pin insertion hole formed in the main house positioning pin insertion plate, and the shaft diameter of the positioning pin inserted therein match each other and are formed differently for each insertion hole row of the main house positioning pin insertion hole.

The specific configuration of the corner valley positioning means includes multiple corner valley pin insertion holes formed at the intersections with corner valley lines determined from multiple types of panel shapes when the purlin support base is positioned according to the roof slope, and corner valley pins that are removably inserted into the corner valley pin insertion holes, and the corner valley pin insertion holes are formed at the intersections with multiple types of corner valley lines that correspond to the multiple types of roof slopes.

In the above-mentioned configuration, it is more preferable that the hole diameter of the corner valley pin insertion hole and the shaft diameter of the corner valley pin match each other and are formed differently for each type of roof slope, while the head diameter of the corner valley pin is uniform regardless of the type of roof slope.

The purlin sheathing panel assembly jig configured as described above is provided with a purlin positioning means for arranging multiple purlin support bases at intervals according to the roof slope, and a corner valley positioning means for determining the corner valley line of the purlin sheathing panel with the purlin support bases in position. After positioning the purlin on the purlin support base using these two means, the sheathing boards can be layered on top of the purlin and joined together to assemble the purlin sheathing panel with high precision.

Furthermore, because these purlin positioning means and corner valley positioning means are designed to accommodate multiple types of roof slopes, it becomes possible to assemble purlin sheathing panels that correspond to multiple types of roof slopes with one set of jigs, dramatically improving workability in the assembly factory.

For multiple types of roof slopes, the row of insertion holes for the main building positioning pin insertion holes that make up the main building positioning means, the diameter of the positioning pin insertion holes formed in the main building positioning pin insertion plate, and the shaft diameter of the positioning pins inserted therein are configured to differ for each roof slope, thereby preventing errors in the main building positioning work.

In addition, by adopting a configuration in which the hole diameter of the corner valley pin insertion hole of the purlin support base that constitutes the corner valley positioning means and the shaft diameter of the corner valley pin inserted therein are different for each roof slope, errors in the positioning work of the corner valley line can be prevented.

The following describes an embodiment of the invention disclosed in this application with reference to the drawings.

Figures 1 and 2 show the overall configuration of a purlin roof panel installation jig according to one embodiment of the invention disclosed in this application. The purlin roof panel installation jig 1 is composed of a base frame 2 and a number of purlin support bases 3 mounted on it.

As shown in Figure 1, the base frame 2 is formed by framing multiple steel sections in a roughly rectangular shape when viewed from above, and is installed horizontally on the work floor F via multiple jack bases 21. Multiple short columns 22 are erected at appropriate intervals on one edge (lower edge in Figure 1) extending in the long side direction (beam direction) of the base frame 2, and the sides of these columns 22 form eaves guides for positioning the eaves line E of the main roof sheathing panel. A sheathing support bracket 23 is also attached to the side of each column 22 to support the edge of the sheathing board 7 (see Figure 2) of the main roof sheathing panel at a specified height.

The base frame 2 is provided with multiple rails 24 (six in the illustrated embodiment) that extend in a direction perpendicular to the eaves line E (beam direction), and these rails 24 movably support the purlin support base 3. The rails 24 are formed by attaching angle irons to the beam material with the corners facing upward.

The base frame 2 is further provided with multiple purlin positioning guides 4 that extend parallel to the rails 24 and position the purlin support base 3 at a predetermined position according to the roof slope. In the illustrated embodiment, a total of four purlin positioning guides 4 are arranged at both ends and the middle part in the long side direction of the base frame 2.

Figure 2 shows a state in which multiple purlin support bases 3 are mounted on the base frame 2 shown in Figure 1. The purlin support bases 3 are mounted on rails 24 with their material length direction parallel to the eaves line E, and each purlin support base 3 moves independently in a direction perpendicular to the eaves line E via running wheels 25 attached to their undersides. In the illustrated embodiment, the purlin support bases 3 (3A, 3B, 3C) are arranged in three rows, two by two, with the length of each being approximately half the length of the long side of the base frame 2.

At the position where the purlin positioning guide 4 and the purlin support base 3 overlap, a purlin positioning means is provided for positioning multiple purlin support bases 3 at intervals according to the roof slope. Figure 3 shows the detailed configuration of the purlin positioning guide 4, and Figures 4 and 5 show the detailed configuration of the purlin support base 3.

The purlin positioning guide 4 is formed by a flat steel strip attached on a shaped steel material, and the steel plate has multiple purlin positioning pin insertion holes 41 formed in it. The purlin positioning pin insertion holes 41 are formed in a row along a direction perpendicular to the eaves line E in order to arrange multiple purlin support bases 3 at a predetermined interval set according to the roof slope. The insertion hole rows of the purlin positioning pin insertion holes 41 are formed in multiple rows corresponding to multiple types of roof slopes (three rows corresponding to roof slopes of 2.5 inches, 4 inches, and 5 inches in the illustrated embodiment), and the hole spacing of each insertion hole row is set to increase as the roof slope increases. Furthermore, the three insertion hole rows have different hole diameters for each row (for each roof slope), and positioning pins 51 with different shaft diameters according to the hole diameter of each row are inserted removably into each insertion hole row.

On the other hand, a purlin positioning pin insertion plate 31 made of a flat steel plate of approximately the same width as the purlin positioning guide 4 is attached to both ends of the purlin support base 3. In the illustrated embodiment, the purlin positioning pin insertion plate 31 has three positioning pin insertion holes 32 formed in each hole row of the purlin positioning pin insertion holes 41 formed in the purlin positioning guide 4.

The purlin support base 3 is moved along the rail 24 in a direction perpendicular to the eaves line E, the positioning pin insertion hole 32 is aligned with the purlin positioning pin insertion hole 41 in the insertion hole row corresponding to the roof slope, and the positioning pin 51 corresponding to the roof slope is inserted, so that the purlin support base 3 is positioned at a predetermined interval set according to the roof slope. By varying the shaft diameter of the positioning pin 51 used according to the roof slope, careless mistakes in the positioning work of the purlin can be prevented. Furthermore, it is also preferable to color the insertion hole row of the purlin positioning pin insertion hole 41, the periphery or inner surface of the positioning pin insertion hole 32 formed in the purlin positioning pin insertion plate 31, and the head of the positioning pin 51 in different colors for each roof slope.

The purlin 6 that constitutes the purlin roof panel is placed on the purlin support base 3 thus positioned. The purlin 6 is made of lightweight steel or wood, and its cross section is rectangular or grooved. To hold both sides of the purlin 6, multiple sets of purlin support pieces 33 that are slightly lower than the height of the purlin 6 are erected on both side edges of the purlin support base 3 so that they face each other at a distance equivalent to the width of the purlin material.

Near one end of the purlin support base 3 in the material length direction, a purlin end contact pin insertion hole 34 is formed, into which a purlin end contact pin 52 is removably attached. When the edge portion of the purlin sheathing panel that follows the roof slope is perpendicular to the eaves line E, the purlin 6 is positioned by abutting its end against this purlin end contact pin 52.

A corner valley positioning means is provided in the middle of the length direction of the purlin support base 3 to determine the position when the edge along the roof slope of the purlin sheathing panel is at an angle to the eaves line E, that is, the corner valley line of the purlin sheathing panel to be installed in the corner or valley of the roof. The corner valley positioning means is composed of multiple corner valley pin insertion holes 35 formed at the intersections with the corner valley lines determined from the shape of the purlin sheathing panel when the purlin support base 3 is positioned according to the roof slope, and corner valley pins 53 that are inserted removably into these holes.

The corner valley pin insertion holes 35 are formed at the intersections with multiple types of corner valley lines that correspond to multiple types of roof slopes. These corner valley pin insertion holes 35 have different hole diameters for each associated roof slope, and corner valley pins 53 with different shaft diameters for each roof slope are inserted into them. However, the head diameter of the corner valley pins 53 is standardized regardless of the type of roof slope.

As shown in Figures 4 and 5, the corner valley pin insertion holes 35 are formed in different positions on the first tier purlin support base 3A, which is located closest to the eaves, the second tier purlin support base 3B, and the purlin support base 3C, which is located closest to the ridge. The purlin is placed on the purlin support base 3 with a corner valley pin 53 inserted into one of the corner valley pin insertion holes 35 corresponding to the roof slope, and the purlin is positioned by butting its end against the corner valley pin 53.

In this way, by using different shaft diameters for the corner valley pins 53 depending on the roof slope, careless mistakes during work can be prevented when positioning the corner valley lines. Furthermore, it is also preferable to paint the area around the corner valley pin insertion hole 35 and the head of the corner valley pin 53 in different colors for each roof slope.

Figures 6 to 11 are top views that show the manner in which the purlin sheathing panel installation jig 1 configured as described above is set to different roof slopes and a triangular purlin sheathing panel is installed on top of it. In each figure, the locations indicated by black circles (●) on the purlin positioning pin insertion plate 31 and the purlin support base 3 are the insertion positions for the positioning pin 51 and the corner valley contact pin 53. Additionally, the diagonal lines shown by dashed dots indicate the positions where the edges of the sheathing board 7 should be aligned.

Figure 6 shows how the purlin roof panel installation jig 1 is set to a roof slope of 2.5 inches, and how a purlin roof panel with a height equivalent to two purlins is installed. Also, Figure 7 shows how the purlin roof panel installation jig 1 is set to a roof slope of 2.5 inches, and how a purlin roof panel with a height equivalent to three purlins is installed. When the length in the girder direction (direction along the eaves line E) is large, two purlin support bases 3A are lined up in a straight line, and the purlin 6 is positioned on top of them.

Figure 8 shows how the purlin roof panel installation jig 1 is set to a roof slope of 4 inches to assemble a purlin roof panel with a height equivalent to two purlins, and Figure 9 shows how the purlin roof panel installation jig 1 is set to a roof slope of 4 inches to assemble a purlin roof panel with a height equivalent to three purlins.

Figure 10 shows how the purlin roof panel installation jig 1 is set to a roof slope of 5 inches to assemble a purlin roof panel with a height equivalent to two purlins, and Figure 11 shows how the purlin roof panel installation jig 1 is set to a roof slope of 5 inches to assemble a purlin roof panel with a height equivalent to three purlins.

In this way, by using the jig 1 for assembling purlin roof panels according to the invention disclosed in this application, it is possible to efficiently assemble purlin roof panels of multiple patterns corresponding to multiple types of roof slopes by changing the spacing of the purlin support bases 3 along the purlin positioning guides 4 and changing the position of the corner valley contact pins 53 attached to the purlin support bases 3. This improves the work efficiency of pre-processing roof panels in factories.
