BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled roof of a carport, an assembled roof mounted on a terrace, or an assembled roof mounted on an approach provided at the entrance of a house. The present invention relates to a method for manufacturing an arcuate purlin tray.

[0002] In this specification, the upper and lower sides when the purlin is incorporated into the assembled roof are referred to as the upper and lower sides. Also,
In this specification, the term "set screw" includes a bolt.

[0003]

2. Description of the Related Art For example, a carport has four columns (10) as shown in FIG.
And an arch-shaped prefabricated roof (11) supported by columns (10). In the following description, the depth direction of the carport is the front-back direction and the frontage direction is the left-right direction.

The assembled roof (11) has a pair of front and rear purlins (12) fixed to the upper ends of the columns (10) at both left and right ends, and the purlins
A pair of left and right eaves girders that are supported by (12) and double as eaves gutters (13)
And a plurality of purlins (14) that are arranged at a distance in the left-right direction between both eaves girders (13) and are supported by purlin receivers (12),
A plurality of slacks (15), which are arranged at intervals in the front-rear direction and supported by the purlin (14), are arranged side by side in the front-rear direction so that the side edges are located above the slacks (15). Multiple roof shingles (1
6) and a roof plate pressing member (17) fixed on each turret (15) and pressing a side edge portion of the roof plate (16).

As shown in FIG. 6, two circular upper and lower circular setscrew insertion holes (18) are formed on the same vertical line at the portion of the upper end of the column (10) intersecting the purlin support (12). There is. Each purlin support (12) is formed in the shape of an arc having the same curvature over the entire length, and two circular set screw insertion holes (at the upper and lower sides of the purlin support) are formed at the portions intersecting with the columns (10) at both ends. 19) has been formed. Again and then
The purlin support (12) has a set screw insertion hole (19) formed at both ends thereof and a set screw insertion hole (18) formed in the column (10).
It is fixed to the column (10) by a bolt (20) (set screw) that is passed through and a nut (not shown) that is screwed into the tip thereof.

The purlin receiver (12) has two circular setscrews inserted through a press using a die with a straight material having an arbitrary length positioned at both ends thereof by pressing with a die. It is manufactured by forming holes (19) and then bending the material into an arc shape by pressing using a mold.

By the way, it is sometimes required to change the frontage of the carport according to the size of the land on which the carport is to be installed, the size of the automobile accommodated in the carport, and the like. In this case, it is necessary to prepare a plurality of types of purlin receivers (12) having different lengths, which results in the following problems. That is, in order to prepare a plurality of types of arcuate purlin trays (12) having different lengths, it is conceivable to make the curvatures the same and change only the lengths. In this case, one type of bending die can be used, and the cost can be reduced. However, as shown in FIG. 7, if the length of the purlin support (12) is different, the purlin support (1)
At the intersection of the end of 2) and the column (10), the angle between the purlin support (12) and the column (10) is different, and the angle (X1) between the short purlin support (12A) and the column (10). Is a long purlin tray (12B) and stanchions
It is larger than the angle (X2) made with (10). As a result, when the length of the purlin support (12) is changed, the positions of the two setscrew insertion holes (19) of the purlin support (12) are set to the positions of the two setscrew insertion holes (18) of the column (10). In order to match the position, for example, assuming that the position of the lower set screw insertion hole (19) is always constant, the position of the upper set screw insertion hole (19) should be set to the lower set screw insertion hole (19). It must be moved on a circumference (O) centered on 19) and having a radius between the two insertion holes (19). Therefore, if the length of the purlin support (12) changes, it is necessary to change the position of the upper set screw insertion hole (19) accordingly, and also the mold for forming the set screw insertion hole (19). There is a problem that multiple types must be prepared accordingly, and the cost increases.

On the contrary, in order not to change the position of the setscrew insertion hole (19) even when the length of the purlin support (12) is changed, a plurality of types of purlin support of different lengths are required. It is necessary to change the curvature of each. Therefore, it is necessary to prepare a plurality of types of bending dies, which also raises the problem of high cost.

An object of the present invention is to provide a method for manufacturing an arcuate purlin receiving member for an assembled roof that solves the above problems.

[0010]

A method of manufacturing an arcuate purlin receiving member for an assembled roof having an arbitrary length according to the present invention has an arcuate shape having the same curvature over the entire length and a portion intersecting with a column at both ends. In this method, two setscrew insertion holes are formed at intervals in the upper and lower sides, respectively, and a purlin support of any length fixed to the support by the set screws passed through the setscrew insertion holes is manufactured. There is one circular set screw insertion hole at each end of a straight material of arbitrary length, and a circular set screw insertion hole on the circumference centered on the center of the set screw insertion hole. A circular arc-shaped set screw insertion hole located in one of the upper and lower sides in the circumferential direction is simultaneously formed using a mold, and then the material is bent into an arc shape using the mold.

[0011]

Operation: A circular set screw insertion hole is provided at each end of a straight material having an arbitrary length, and a circular set screw insertion hole is formed on the circumference around the center of the set screw insertion hole. A purlin support is manufactured by simultaneously forming a circular arc-shaped set screw insertion hole located in one of the upper and lower sides using a mold, and then bending the material into an arc using the mold. Therefore, no matter what length of purlin support is manufactured, the vertical line passing through the center of the circular set screw insertion hole is
It will always intersect with the circular arc shaped set screw insertion hole, and if the positions of the circular shaped set screw insertion hole and one set screw insertion hole of the support are matched, the other set screw insertion holes of the support will be circular. It will exist within the range of the arc-shaped set screw insertion hole. Therefore, even when preparing multiple types of purlin supports with different lengths, it is not necessary to make the curvature of each purlin support the same and to change the forming position of the setscrew insertion hole. One type of mold can be used for each.

Embodiments of the present invention will be described below with reference to the drawings.

In manufacturing a plurality of arcuate purlin supports having different lengths, first, a plurality of kinds of straight aluminum (including aluminum alloy) extruded shape raw materials having different lengths are prepared, and at both ends of each raw material, By a pressing process using a punching die (not shown), one circular shaped set screw insertion hole is provided, and the set screw is placed on the circumference around the center of the set screw insertion hole and above the predetermined position. An arcuate set screw insertion hole that is long in the circumferential direction is formed at the same time. The positions of both setscrew insertion holes at both ends of all materials are at the same position with respect to the corners of each end. Further, regarding the circumferential length of the arcuate set screw insertion hole, for example, when considering the width of changing the frontage of the carport, when the frontage is the narrowest, that is, the length of the purlin support to be manufactured is the shortest. , And vice versa, that is, when the length of the purlin support to be manufactured becomes the longest, the center of the circular set screw insertion hole in the manufactured purlin support The length of the vertical line passing through should intersect with the arcuate set screw insertion hole. Then, each material is bent by a press using a bending die (not shown) to form an arc shape having the same curvature over the entire length. Thus, as shown in FIGS. 1 (a) to 1 (c), one circular set screw insertion hole has different lengths and is provided at both ends.
(2) and a circular arc-shaped set screw insertion hole (3) circumferentially located around the center of the set screw insertion hole (2) and above the predetermined position. A plurality of arcuate purlin receivers (1A) (1B) (1C) are manufactured.

Purlin trays (1A) (1B) (1C) manufactured in this way
In Fig. 2 to 4, the vertical line (V) passing through the center of the circular set screw insertion hole (2) always intersects with the arc shaped set screw insertion hole (3). , Purlin ((1
At the intersection of the end of A) (1B) (1C) and the pillar (10), even if the angle between the purlin supports (1A) (1B) (1C) and the pillar (10) is different, a circular stop If the positions of the screw insertion hole (2) and the lower set screw insertion hole (18) of the column (10) are aligned, the column (10)
The set screw insertion hole (18) on the upper side of is the arc-shaped set screw insertion hole.
It exists within the range of (3). Therefore, the purlin receivers (1A) (1B) (1C) and the support columns (10) can be fixed by the bolts (20) and nuts that are passed through the insertion holes (2) (3) (18).

In the above description, the circular arc-shaped set screw insertion hole is formed above the circular shaped set screw insertion hole. On the contrary, the set screw insertion hole is formed below the circular shaped set screw insertion hole. The same applies to the case of forming an arcuate set screw insertion hole that is long in the circumferential direction, which is on the circumference centered on the center of.

[0016]

According to the method of manufacturing the arcuate purlin receiving member for an assembled roof of the present invention, both setscrew insertion holes are provided even when a plurality of types of purlin receiving members having different lengths are prepared as described above. As the mold for simultaneously forming and the bending mold, one kind can be used regardless of the length of the purlin support to be manufactured. Therefore, the cost for preparing these molds becomes low.
