Description

[Detailed Description of the Invention] The present invention consists of a pair of right triangular roof trusses 1a and 1b arranged in a straight line in the left-right direction, each of which has vertical pieces 2a and 2.
This is a roof made by joining the front and rear surfaces of roof trusses 1a and 1b so as to overlap and placing the horizontal pieces 3a, y3b3b of each roof truss 1a and 1b on a vertical structural member 4, and its purpose is to To provide a roof which can easily construct a large-sized roof assembly or an irregularly shaped roof assembly such as a beckoning roof, and which makes it difficult for joint parts to separate.

The present invention will be explained in detail below using examples.

The roof trusses 1a and Ib are formed by combining structural members with a cross section of 2 x 4, and are formed into a substantially right triangular shape using a connector 5 called a king nail, and in the embodiment shown in FIG.
Composite truss A combining two roof trusses 1a and -1b
An example of configuring a beckoning roof is shown, with each roof truss 1
Arrange the horizontal pieces 3a and 3b of a and 1b in a straight line in the left-right direction, overlap the front and rear surfaces of both vertical pieces 2a and 2b, and drive nails 6 into both vertical pieces 2a+2b in the front-rear direction to form both roof trusses la. , 1b, and the lower surface of the joined portion of the vertical pieces 2a, 2b, each having a substantially square cross section, and the outer tip of each horizontal piece 3a, 3b are placed on the vertical structural member 4.

In the illustrated embodiment, a load-bearing wall is used as the vertical structural member 4,
The load-bearing wall is constructed by pasting panels 9 to a framework 8 made of a structural material with a cross section of 2 x 4 similar to the above, and a plurality of load-bearing walls 4 are made of a head joint 10 made of the same structural material. and the roof truss 1a through this head joint 10.
1b is stopped, and by joining the load-bearing walls 4, the frame 8 is butted at the joint, and the frame 8 is placed on the structural member constituting the column 20, which has a square cross section, through the head joint 10. The overlapping portions of the square-shaped vertical pieces 2a and 2b increase the structural strength.

Composite truss A placed on the vertical structural member 4 in this way
are arranged in parallel, and a haze 12 connecting the diagonal pieces 7a and 7b of each roof truss 1a and 1b and the diagonal pieces 7a and 7 are arranged in parallel.
A roof board 13 is laid on the upper surface of b, and the diagonal piece 7 protrudes above the tip of each diagonal piece 7a, 7b and one roof truss 1a.
Connect the tip of a with Hanamoya 15 and connect Hanamoya 15
A nose plate 16 is attached to the outer surface of the roof to form an inviting roof.

In the embodiment described above, an example was shown in which two large and small roof trusses 1a and 1b were combined to form a composite truss A, but the present invention is not necessarily limited to this.
, b, roof trusses la and lb of the same shape are combined to form a roof with a large span, or roof trusses 1a and Ib of the same height but with different slopes are combined to form a roof with a large span. It is possible to form a roof that is large in size and has a variety of shapes.

As described above, the present invention connects the vertical pieces of a pair of right-angled triangular roof trusses, and also places both ends of the horizontal pieces of each roof truss on vertical structural members. By assembling roof trusses of various shapes at the factory stage, these roof trusses can be assembled on site to create roofs with large spans and unique roof shapes with many variations, such as a beckoning roof. It can be easily constructed.

In addition, the front and rear surfaces of each vertical piece of the roof truss, which are arranged in a straight line in the left and right direction, were joined together so that they overlapped, so the direction in which the vertical pieces were fixed with nails, etc. was in the front and back direction, and the roof truss was arranged in a straight line in the left and right direction. Even if a horizontal force acts on the roof truss in the left-right direction, the fixing devices such as nails act as resistance at the joints between the roof trusses, and the joint between both roof trusses does not come loose.

Moreover, since both ends of the horizontal side of each roof truss are placed on the vertical structural members, the joints between the roof trusses are also located on the vertical structural members, and as a result, the load from the joints between the roof trusses is directly transferred vertically. This has the advantage that it can be transmitted to the structural members, and that no excessive force is applied to the joints between the roof trusses, and the joints do not separate.
