Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a roof structure for an assembling type simple garage, which is intended to simplify the roof construction and save labor in the construction.

2. Description of the Related Art As a roof structure of this type of garage, there is known a structure in which a receiving metal fitting is fixed to a predetermined position of a rafter, and a side end of a purlin material is fitted and fixed to the receiving metal fitting. (Actual number 61-3802, 6)
No. 2-196812, No. 61-20701) Also, a structure in which a projecting piece is formed on the side of a rafter, and a notch is formed in this to fit a purlin material, is described in Japanese Utility Model Publication No. 60-179729. Has been done.

Problems to be Solved by the Invention The roof structure using the brackets for connecting the rafter and the main building material is very troublesome because it requires a large amount of work in a high place even though the connection strength is large.

Further, according to the roof structure described in Japanese Utility Model Laid-Open No. 60-179729, since the notch is formed in the rafter projecting piece and the end of the purlin is fitted into this notch, if the notch is large, there is backlash. It may occur and the main building material may easily come off. On the other hand, if the notch is small, the work of fitting the purlin material becomes troublesome and the workability deteriorates.

Furthermore, since the rafter and the main building material are simply fitted together, the vertical position of the main building material is not regulated and the main building material sometimes comes off unless the installation work of the main building material on the rafter is done carefully. There was a drawback.

Means for Solving the Problems As a result of studying in view of such circumstances, the present inventors have formed protrusions on the upper and lower side portions in the longitudinal direction of the rafter,
In the roof structure of the prefabricated garage, in which a notch is provided in the upper projection of the rafter, the side edge of the main material is inserted into the notch position of the upper projection and placed on the upper portion of the lower projection, The shape is approximately U-shaped with the width of the upper part larger than the notch of the rafter and the upper part is open, and a ridge is formed on the outside in the longitudinal direction of the main building material, and the side end of the main building material is an upper projecting piece. The initial purpose is achieved by elastically abutting the notch edge and locking the ridge of the purlin material to the upper projecting piece.

Effect According to the present invention, since the main building material is U-shaped with the upper side opened, both side parts of the main building material can be elastically deformed inward, and therefore, for rafters arranged at a predetermined interval. Then, it is possible to press-fit a purlin material having a side portion wider than the cutout of the rafter from above and fit it together.

In this plan, after fitting the lower part of the main building material to the notches of adjacent rafters and suspending it, and pressing the side edge of the main building material from above, the width at the upper part of the main building material is larger than the notch of the rafter and Since the protrusions are formed on the outside in the longitudinal direction of the purlin, the ends of the purlins elastically abut the cutout edges of the rafters, and the protrusions of the purlins on the upper protrusions of the rafters. Both can be locked and fixed integrally.

Examples The drawings show an example of the present invention, in which a lower projection (2) (2) (having an upward projecting edge (3) along the longitudinal direction is provided at the lower portions on both sides of a rafter (1) (1) made of an aluminum molded material. 2)
To form an upper projecting piece (4) in the upper part on both sides of the rafter (1) in the longitudinal direction, and a purlin (6) for the projecting piece (4).
Are provided at the positions for attaching the notches (5), (5), ... Corresponding to the width of the lower part of the purlin (6), and the purlin (6) having a U-shaped cross-section with an open upper part made of an aluminum molding material.
(6) ... has a width in the upper part larger than the notch of the rafters (1) and forms ridges (7) and (7) on the outside in the longitudinal direction of the purlin (6), thereby forming the rafters (1). The both ends of the purlin (6) are pressed into the notches (5) from above and inserted into the notches (5), the both ends of the purlin (6) are elastically brought into contact with the notch edges (41) of the rafters (1), and The ridges (7) and (7) of the main building material (6) are locked to the lower surface of the upper protrusion (4) of the rafter (1) to fix both members.

In the figure, (8) is a roof material, (9) is a draining member, (10) is a roof retainer, and (11) is a tapping screw.

Effect of the Invention According to the present invention, the labor of assembling the rafters and the purlins on the roof of the simple garage can be significantly reduced.

Further, since the side edge of the purlin material elastically abuts the notch edge of the rafter and the ridge of the purlin material is locked to the upper projection of the rafter, the position of the purlin material with respect to the rafter is restricted. Purlin materials can be attached immovably.
