発明の名称 (英語) Wall construction of architectural structure
発明の概要(英語) (US7836646)
A wall structure of an architecture is provided, which comprises an outer wall having resistance against earthquakes and wind and an inner wall relatively inferior in the earthquake-resistance and so forth, so that the outer and inner walls are properly combined to share design loads.
The wall structure includes the outer wall (2) of bricklaying structure in which bricks (A˜D) and metal plates (51) are stacked.
Fasteners (60,62,63,70) extending through the bolt holes (7) of the bricks are tightened, and the vertically adjacent bricks are integrally connected with each other under prestress of the fasteners.
The inner wall (3) is constructed inside of the outer wall, and the shear reinforcement member (10,20) connects the inner and outer walls with each other.
The inner wall is constructed by a dry type of construction method, which can support a permanent vertical load such as a roof load.
A temporary horizontal load acting on the inner wall, such as a seismic force, is transmitted to the outer wall by the shear reinforcement member.
特許請求の範囲(英語) [claim1]
1. A wall construction for a building structure having a roof and a foundation for defining an internal space of the building structure, the wall construction comprising: an outer wall sharing its own dead load and built on the foundation of the structure, wherein the outer wall has a Distributed and Unbonded Prestress bricklaying construction in which bricks and metal plates are stacked, the bricks and the metal plates have bolt holes therein, fasteners extend through the bolt holes in the bricks and the bolt holes of the metal plates, and the fasteners are tightened so that vertically adjacent bricks are integrally connected with each other under prestress of the fasteners, each of the metal plates being interposed between upper and lower vertically adjacent bricks to be in contact with an upper face of the lower brick and a lower face of the upper brick under the prestress;
an inner wall sharing its own dead load and constructed to support a vertical load of the roof, wherein the inner wall defines the internal space in conjunction with the roof and the foundation; and
a shear reinforcement member made of a metal plate extending along the inner and outer walls, wherein the shear reinforcement member connects the outer wall and the inner wall with each other and transmits a shearing force of the inner wall to the outer wall, wherein the shear reinforcement member has an inner end portion fixed to the inner wall, and an outer end portion positioned on at least one brick or between vertically adjacent courses of the bricks and fixed to an upper surface of the at least one brick by a tightening force of the fastener, for transmitting a seismic force acting on the roof and the inner wall to the outer wall by means of the shear reinforcement member.
[claim2]
2. The wall construction as defined in claim 1, wherein the shear reinforcement member has an overall length such that the member extends over the bricks.
[claim3]
3. The wall construction as defined in claim 1, wherein a temporary allowable shear force of the outer wall is in proportion to the prestress applied to the fastener.
[claim4]
4. The wall construction as defined in claim 3, wherein the temporary allowable shear force QAS of the outer wall is determined by the following formula:
QAS=t.j.mu .NP/A
wherein t: effective thickness of the wall,
j: distance between centers of tension and compression in the wall,
NP: total amount of prestress (force) applied to a layer which causes slippage,
mu : the coefficient of friction between the brick and a contact surface of a horizontal reinforcement plate,
A: effective cross-sectional area of the wall.
[claim5]
5. The wall structure as defined in claim 1, wherein the shear reinforcement member comprises: a first bracket on a side of the outer wall, the first bracket being located on the brick or between the bricks and being secured to the upper face of the brick by the tightening force of the fastener, and
a second bracket on a side of the inner wall side tightly secured to a component of the inner wall, and wherein the brackets on the outer and inner wall sides are connected with each other in a stress transferable condition.
[claim6]
6. A building structure comprising a plurality of wall constructions as defined in claim 1, a roof, and a foundation, wherein the inner wall of each of the wall constructions has an upper end and the roof is supported by the upper ends of the inner walls.
[claim7]
7. A wall construction of a building structure having a roof and a foundation for defining an internal space of the building structure, the wall construction comprising: a double wall structure of an outer wall and an inner wall, wherein: the outer wall shares its own dead load and built on the foundation of the structure, the outer wall has sufficient strength for sharing its own dead load and a temporary horizontal load acting on the outer wall and the inner wall, and the outer wall has a Distributed and Unbonded Prestress bricklaying construction in which bricks and metal plates are stacked, the bricks and the metal plates have bolt holes therein, fasteners extend through the bolt holes in the bricks and the bolt holes of the metal plates, and the fasteners are tightened so that vertically adjacent bricks are integrally connected with each other under prestress of the fasteners, each of the metal plates being interposed between the vertically adjacent bricks to be in contact with an upper face of the lower brick and a lower face of the upper brick under the prestress; and
the inner wall has sufficient strength for sharing its own dead load and a permanent vertical load acting on the inner wall, wherein the inner wall defines the internal space in conjunction with the roof and the foundation; and
a shear reinforcement member connecting the outer and inner walls with each other and made of a metal plate extending along the inner and outer walls and transmitting a shearing force of the inner wall to the outer wall, wherein the shear reinforcement member has an outer end portion positioned on at least one brick or between vertically adjacent courses of the bricks and fixed to an upper surface of the at least one brick by a tightening force of the fastener, for transmitting a seismic force acting on the roof and the inner wall to the outer wall by the shear reinforcement member.
[claim8]
8. The wall construction as defined in claim 7, wherein the shear reinforcement member has an overall length such that the member extends over the bricks.
[claim9]
9. The wall construction as defined in claim 7, wherein a temporary allowable shear force of the outer wall is in proportion to the prestress applied to the fastener.
[claim10]
10. The wall construction as defined in claim 9, wherein the temporary allowable shear force QAS of the outer wall is determined by the following formula:
QAS=t.j.mu .NP/A
wherein t: effective thickness of the wall,
j: distance between centers of tension and compression in the wall,
NP: total amount of prestress (force) applied to a layer which causes slippage,
mu : the coefficient of friction between the brick and a contact surface of a horizontal reinforcement plate,
A: effective cross-sectional area of the wall.
[claim11]
11. A building structure comprising a plurality of wall constructions as defined in claim 7, a roof, and a foundation, wherein the inner wall of each of the wall constructions has an upper end and the roof is supported by the upper ends of the inner walls.
