Abstract

PROBLEM TO BE SOLVED: To precisely support a diagonal member without needing working of a troublesome horizontal member, simplify adjustment of an error and secure execution quality according to a plan by attaching a laying plate provided with an inclination face mounting the diagonal member of a rafter, an angle rafter, a valley rafter and the like on the upper face of the horizontal member such as a purlin and ridge beam. SOLUTION: When a wooden roof truss is composed of square timber downward inclined toward an eaves direction on a purlin 10 composed of the square timber and a rafter 13 obliquely intersected for the purlin 10 is supported, a laying plate 11 is attached to the upper face of the purlin 10 fixed through a connection fitting such as a tenon pipe on the upper face of a strut by nail driving and the like. The laying plate 11 is formed in the form of a cross section right angled triangle provided with an inclination face 12 downward inclined toward the eaves direction, and disposed over an eaves side end which is a longitudinal end from the center of the upper face of the purlin 10. The flat lower face of the rafter 13 is mounted on the inclination face 12 of the laying plate 11, and a nail 14 is driven toward the laying plate 11 from the side of the rafter 13.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for supporting diagonal members such as rafters, summit trees, etc. on cross members such as purlins and purlins.

[0002]

2. Description of the Related Art Diagonal members such as rafters, corners and valleys in a hut are supported by cross members such as purlins, eaves and purlins. FIG. 6 shows a supporting structure of rafters in a conventional purlin, and an inclined surface (2) formed by diagonally notching from the center of the upper surface of the purlin (1) to the end on the eaves tip side.
A rafter (3) was placed on the rafter, and a nail (4) was driven into the purlin (1) from the side of the rafter (3) to support the rafter (3). Similarly, the corner trees and the valleys were also placed on an inclined surface formed in a horizontal member such as a purlin, and supported by driving nails.

[0003]

However, in the prior art, since the inclined surface is formed by processing the cross member itself such as a purlin, the processing is troublesome, and the processing accuracy tends to vary. Further, there is a problem that it is difficult to perform adjustment when an error occurs in the inclination angle of the diagonal material. Further, there is also a problem that the material is wasted by the amount of the cutout, and the height of the roof is lowered, so that the construction quality as planned cannot be ensured.

[0004] In view of the above, the present invention does not require complicated processing of cross members, can accurately support diagonal members, can easily adjust errors, and can secure the construction quality as planned. The purpose of the present invention is to provide a support structure for diagonal members in a set.

[0005]

Means for solving the above problem are as follows. A bottom plate having an inclined surface on which a diagonal member such as a rafter, a summit tree is placed is mounted on the upper surface of a cross member such as a purlin or a purlin. It was done.

[0006] The floor plate is formed in a triangular cross section and is arranged from the center of the upper surface of the cross member to one end in the longitudinal direction.

Further, when a plurality of floor boards are combined so that their inclined surfaces intersect with a mountain or a valley, a lower surface of a chevron or a valley of a valley is placed at the intersection. These can be stably supported.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, the floor plate is not limited to a right triangle in cross section, and may have a trapezoidal cross section as long as it has an inclined surface on which a horizontal member is placed. In addition to the main building and the purlin, a floor board may be attached to the eaves girder to support the rafters and the summit trees.

[0023]

As is apparent from the above description, according to the present invention, since the sloping material is supported by newly attaching a floor plate to the upper surface of the stiffening material, the stiffening material itself is troublesome and easily varies. It is possible to accurately support the diagonal material without requiring any processing.

Further, even if an error occurs in the inclination angle or the like of the diagonal material when the diagonal material is supported, only the sole plate is replaced,
It is possible to easily adjust the error, such as removing the base plate and shaving it at a place with good scaffolding.

Furthermore, since the cross members are not cut out, the waste of materials can be eliminated, and the problem that the height of the roof is reduced unlike the conventional case does not occur, and the construction quality as designed can be ensured. it can.

Further, by disposing the bottom plate having a triangular cross section from the center of the upper surface of the cross member to one end in the longitudinal direction, the diagonal member can be stably supported, and the minimum necessary material can be used. The sole plate can be configured, and material can be saved.

Further, by combining a plurality of floor boards,
If the inclined surface intersects with a chevron or a valley, even if the lower surface of a corner or a valley is formed in a chevron or a valley, by placing this lower surface on a portion where the inclined surface intersects, These corner trees and valleys can be stably supported, and a highly versatile support structure can be provided.
