Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an arch-shaped roof of a wooden building, and more particularly to a roof construction structure for constructing an arch-shaped roof with arch materials formed by laminating long plate materials. .

2. Description of the Related Art Conventionally, as a roof assembly structure, it is known that a plurality of single-type or double-shaped arch materials, which are formed by laminating long plate materials, are arranged in parallel, and columns are joined to both sides of each arch material to construct a roof assembly. ing. Since all of them have high proof strength against vertical load and can construct a building with large frontage, they are widely used as arch-shaped roof-structured structures such as livestock houses, warehouses, factories, and gymnasiums. .

Problems to be Solved by the Invention However, in the above roof structure, the number of laminated arched materials and the number of used arched materials are determined from the strength calculation based on the building standards. Construction is performed using a predetermined number of timbers, and all of these arch materials have the problem that the material consumption becomes unnecessarily large and the construction cost increases due to the fact that they are all supported by solid pillars.

Further, in the case of a structure in which both ends of the arch material are supported by columns, there is a problem that the joint portion between the columns and the arch material becomes a structural weak point. In order to overcome the weakness of the joint between the arch material and the pillar,
For example, when considering using a single arch material in which all parts corresponding to roofs and columns are laminated board structure, it is not possible to secure the internal space efficiently, and it also induces snow fall in heavy snow areas. It is easy, lacks safety, and has a full arch, which makes it difficult to secure a foothold during construction, when changing the roof, or when it snows.

The present invention provides a roof construction structure using a laminated arch material that effectively solves the above problems.

Means for Solving the Problems That is, according to the present invention, an arch-shaped roofing portion is formed by a central arch portion of an arch material formed by laminating a plurality of long plate materials, and is installed on a base on both sides of the central arch portion. A roof assembly in which a leg to be attached is formed, a vertical wall is constructed on the side of the leg, and a one-way roof is provided at the upper end of the vertical wall and the base end of which is connected to the end of the arch-shaped roofing part. In the structure, the chord member of the laminated plate structure is laid across the arch member,
Both ends of the chord are connected near the connecting portion of the arch-shaped roofing part and the legs, and both ends of the chord are connected to the upper end of the vertical wall to construct a second floor floor set on the chord. Is.

Operation In the present invention, the arch-shaped roofing part is formed by the central arch part of the laminated plate-shaped arch material, and the leg parts to be mounted as base are formed on both sides of the central arch part, and the lateral sides of the leg parts are formed. A vertical wall is constructed, and a one-sided roof is provided at the upper end of the vertical wall, and the base end of the vertical wall is connected to the end of the arch-shaped roofing part.
The roof structure is constructed.

This eliminates structural weaknesses at the joint between the pillar and the arch material, while effectively securing the internal space by the side wall formed on the side of the leg of the arch material and the construction space by the one-way roof, and the side structure Thus, snowfall from the arch-shaped roofing part can be received by the one-sided roof, and can be utilized as a scaffold for construction or snowfall, and the problems of safety and workability can be solved.

Further, in the above roof structure, a chord member having a laminated plate structure is laterally laid on the arch member, and both ends of the chord member are connected near the connecting portion of the arch-shaped roofing portion and the leg portion, and the chord member is connected. Since both ends of the timber are connected to the upper end of the vertical wall to construct a second floor floor set on the chord member, while strengthening the vertical load and side load of the roofing structure of the arch material By constructing a two-story structure that effectively uses the internal space of the arch material, by connecting both ends of the chord material to the area where the arch-shaped roofing part and legs are connected, and by connecting to the vertical wall of the lower house , Effectively contribute as a beam material for the purlins formed under the arch material and the shedhouse formed outside the legs of the arch material,
In addition, a second-floor set can be constructed near the one-way roof part of the lower house by this beam material, and the design of the second-floor part for the lower house corresponding to the first-floor part can be rationally formed.

In addition, since the chords that form the beams of the building and the legs that will be the pillars are made of a laminated plate structure, not only can strength be expected to be improved, but also a reduction in construction cost can be achieved compared to the case of using solid timber. .
