Description

  The present invention relates to a wooden truss building that is effective for buildings such as livestock barns and compost fermenters where ammonia gas is frequently generated.

The livestock barn and compost fermentation house generate a lot of ammonia gas, the steel structure is very rusted, and the wood connection of the wooden barn with the conventional method is a pin connection, so the shape changes easily by tension and compression.
Conventionally, a wooden truss structure is very widely used as a wooden structure. The reason is that the wooden truss structure can be constructed very easily and can carry very large loads.

Therefore, a wooden truss structure that constitutes a framework for a triangular truss roof is known (see cited document 1).
In this known technique, each beam member is composed of at least three basic plate members that are nailed together, and the plate member located in the center is offset with respect to the plate members on both sides, whereby a panel is formed at a joint portion that forms a node. A tenon and / or mortise is formed to insert the form reinforcement, and the panel joined at the joint site (node) supplements the nail area and resists greater forces. It can be done.

Moreover, the composite structure building which does not require reinforcement of a frame structure part is known by suppressing the deformation | transformation of a frame structure part by the roof part which made the frame structure main structure (refer the cited reference 2).
This known technique is a composite structure building composed of a roof portion formed with a truss as a main structure and an RC portion formed of reinforced concrete that supports the roof portion from below. A horizontal truss structure including at least a part of the land beam is provided to reinforce at least one end surface of the upper end surface of the girder side wall and the upper end surface of the girder side wall. It is what.

  An object of this invention is to provide the wooden truss building which comprises the frame | skeleton for the roof of a triangular truss which is effective for buildings, such as a livestock barn and a compost fermentation house with much generation | occurrence | production of ammonia gas.

The wooden truss building of the present invention includes a land beam arranged along the upper end surface of the side wall of the wife, a joint placed at the end of the land beam and arranged in accordance with the slope of the roof, and between the land beam and the joint. The diagonal members arranged diagonally so as to form a triangular truss, the land beams and the joints, the land beams and the diagonal members, the joints and the diagonal members are brought into contact with each other, and each is sandwiched and bonded. -It consists of a coupling plate that is fixed by nailing.
The method for assembling a wooden truss building of the present invention includes a land plate and a joint, a land plate and an oblique member, a joint plate fixed to a joint portion of the joint and the oblique member, and the land beam and the joint, the land beam and the oblique member. The material, the palm and the diagonal material are sandwiched and fixed with adhesives, respectively, and the structural strength is calculated, and a plurality of nails x multiple rows are driven from both sides.

The wooden truss building of the present invention includes a land beam arranged along the upper end surface of the side wall of the wife, a joint placed at the end of the land beam and arranged in accordance with the slope of the roof, and between the land beam and the joint. The diagonal members arranged diagonally so as to form a triangular truss, the land beams and the joints, the land beams and the diagonal members, the joints and the diagonal members are brought into contact with each other, and each is sandwiched and bonded.・ Because it is composed of a connecting plate that is fixed by nailing, it is difficult to produce a shape change due to tension / compression of the wood joint as a truss shape by rigid joining, and the joint (node) is not a hardware structure. Corresponding to rust is taken as a plywood for use, and an adhesive can be applied to the joint (node) to ensure strength.
The method of assembling a wooden truss building of the present invention cannot be calculated with an adhesive in terms of structural calculation. Therefore, the structural strength calculation is cleared by nailing, and the joint is reinforced with an adhesive. The strength does not decrease significantly.
