Abstract

This building comprises a foundation, a main building part that is provided to the foundation and that has a framework structure, and a roof that is provided to the main building part and that has a truss structure. Moreover, a method for constructing the building includes: a first step for forming the foundation; a second step for creating the main building part having a framework structure on the foundation; and a third step for attaching, to the main building part, a roof frame having a pre-assembled truss structure.

First claim

The invention claimed is:

1. A building, comprising:
a foundation;
a building body arranged on the foundation, the building body having a Rahmen structure;
a roof arranged on the building body, the roof having a truss structure; and
metal fittings,

wherein:
the building body includes:
vertical members;
first horizontal members extending between the vertical members; and
second horizontal members extending between the first horizontal members, the second horizontal members intersecting the first horizontal members,

the roof includes roof frames,
at least one roof frame includes:
a roof extending member spanning two of the first horizontal members or two of the second horizontal members;
rafters coupled to the roof extending member; and
a reinforcement member arranged so as to form the truss structure in an outer frame that is defined by the roof extending member and the rafters,

the at least one roof frame is fixed to at least one first horizontal member or at least one second horizontal member using at least one metal fitting,
the at least one metal fitting includes a fixed portion, two tabs and an attachment portion,
the fixed portion is configured to extend away from the at least one roof frame along an upper surface of the at least one first horizontal member or the at least one second horizontal member to which the at least one roof frame is fixed,
the fixed portion includes a first edge portion and a second edge portion, and is fixed to the at least one first horizontal member or the at least one second horizontal member to which the at least one roof frame is fixed,
the first edge portion includes an inclined portion that is inclined with respect to an extending direction of the at least one first horizontal member or the at least one second horizontal member to which the fixed portion is fixed,
the two tabs protrude from the inclined portion of the fixed portion and sandwich the roof extending member,
a distance between the inclined portion and the second edge portion narrows as a distance from the roof extending member sandwiched by the two tabs increases,
the attachment portion is configured to extend in one direction from each of the two tabs along the roof extending member sandwiched by the two tabs, and
at a portion where the roof extending member intersects the at least one first horizontal member or the at least one second horizontal member, the at least one metal fitting fixes the roof extending member to the at least one first horizontal member or the at least one second horizontal member.

2. The building according to claim 1 , wherein:
the building body further includes one or more frame members arranged between two of the vertical members, and
each of the one or more frame members with a rectangular frame shape includes a top portion, a bottom portion, and opposing side portions.

3. The building according to claim 2 , wherein each of the one or more frame members is formed using dimensional lumber that has a smaller cross-sectional area than the vertical members, the first horizontal members, and the second horizontal members.

4. The building according to claim 2 , wherein:
each of the one or more frame members has a space defined by the top portion, the bottom portion, and the opposing side portions,
each of the opposing side portions is in contact with at least one of the vertical members, and extends along the at least one of the vertical members,
the top portion is in contact with at least one of the first horizontal members and second horizontal members, and extends along the at least one of the first horizontal members and the second horizontal members, and
the bottom portion is in contact with the foundation, and extends along the foundation.

5. The building according to claim 2 , wherein:
the opposing side portions are respectively fixed to the two of the vertical members using screws or bolts, and
the top portion is fixed to one of the first horizontal members and the second horizontal members using screws or bolts.

6. The building according to claim 2 , wherein:
each of the one or more frame members further includes a coupling member,
the coupling member connects the opposing side portions together,
the coupling member is arranged between the top portion and the bottom portion, and
the coupling member extends parallel to the top portion and the bottom portion.

7. A building, comprising:
a foundation;
a building body arranged on the foundation, the building body having a Rahmen structure;
a roof arranged on the building body, the roof having a truss structure; and
metal fittings,

wherein:
the building body includes:
vertical members;
first horizontal members extending between the vertical members; and
second horizontal members extending between the first horizontal members, the second horizontal members intersecting the first horizontal members,

the roof includes roof frames and a coupling member that couples the roof frames to each other,
at least one roof frame includes:
a roof extending member;
rafters coupled to the roof extending member; and
a reinforcement member arranged so as to form the truss structure in an outer frame that is defined by the roof extending member and the rafters,

the coupling member that couples the roof frames to each other is fixed to at least one first horizontal member or at least one second horizontal member using at least one metal fitting,
the at least one metal fitting includes a fixed portion, two tabs and an attachment portion,
the fixed portion is configured to extend away from the coupling member along an upper surface of the at least one first horizontal member or the at least one second horizontal member to which the coupling member is fixed,
the fixed portion includes a first edge portion and a second edge portion, and is fixed to the at least one first horizontal member or the at least one second horizontal member to which the coupling member is fixed,
the first edge portion includes an inclined portion that is inclined with respect to an extending direction of the at least one first horizontal member or the at least one second horizontal member to which the fixed portion is fixed,
the two tabs protrude from the inclined portion of the fixed portion and sandwich the coupling member,
a distance between the inclined portion and the second edge portion narrows as a distance from the coupling member sandwiched by the two tabs increases,
the attachment portion is configured to extend in one direction from each of the two tabs along the coupling member sandwiched by the two tabs, and
at a portion where the coupling member intersects the at least one first horizontal member or the at least one second horizontal member, the at least one metal fitting fixes the coupling member to the at least one first horizontal member or the at least one second horizontal member.

8. The building according to claim 7 , wherein:
the building body further includes one or more frame members arranged between two of the vertical members, and
each of the one or more frame members with a rectangular frame shape includes a top portion, a bottom portion, and opposing side portions.

9. The building according to claim 8 , wherein each of the one or more frame members is formed using dimensional lumber that has a smaller cross-sectional area than the vertical members, the first horizontal members, and the second horizontal members.

10. The building according to claim 8 , wherein:
each of the one or more frame members has a space defined by the top portion, the bottom portion, and the opposing side portions,
each of the opposing side portions is in contact with at least one
