Bricklaying structure, bricklaying method, and brick manufacturing method

1. A bricklaying structure comprising bricks and metal plates stacked, and fastening means extending through bolt holes of the bricks and metal plates, the fastening means securely tightened to integrally connect the vertically adjacent bricks under pre-stress,

wherein each brick is provided with a bolt hole of a small diameter vertically extending through the brick and at least two through-holes having a diameter larger than the diameter of said bolt hole, the diameter of said bolt hole allowing a bolt constituting said fastening means to extend therethrough,

said diameter of said through-holes for containing a nut constituting said fastening means, which can be engaged with said bolt,

said bolt hole and said through-holes being arranged on a longitudinal center line of said brick, and a center of said bolt hole, centers of said through-holes and respective end faces of said bricks being spaced apart an equal distance from each other in a longitudinal direction of said bricks.

2. The bricklaying structure as defined in claim 1 , wherein said end faces of the bricks are provided with a vertical groove in a form of semicircle, a center of curvature of the groove being positioned on said center line, and the vertical groove providing a vertical channel in cooperation with a vertical groove of an adjacent brick, the channel having a diameter for containing the nut.

3. The bricklaying structure as defined in claim 2 , wherein said through-holes form a vertically continuous hole through which a long bolt of a large diameter can be inserted when the bricks are laid in a condition that said bricks are alternately oriented at a right angle with each other and that said through-holes are vertically in alignment with each other.

4. The bricklaying structure as defined in claim 1 , wherein said through-holes form a vertically continuous hole through which a long bolt can be inserted, when the bricks are laid in a condition that said bricks are alternately oriented at a right angle with each other and that said through-holes are vertically in alignment with each other.

5. A bricklaying method in which bricks and metal plates with bolt holes are alternately stacked and small diameter bolts extending through said bolt holes are securely tightened to vertically and integrally connect said bricks with each other, while giving pre-stress to said bolts, comprising the steps of:

stacking corner bricks, each having a through-hole vertically extending therethrough with a diameter of said through-hole being larger than a diameter of said bolt holes, so that stacked through-holes are vertically arranged in alignment with each other; and

inserting, through said through-hole, a large diameter long bolt having a diameter larger than that of said small diameter bolts, and securely tightening said corner bricks by said long bolt.

6. The bricklaying method as defined in claim 5 , wherein a straight wall is constructed by laying regular bricks, each regular brick having a raised center part on its top face and a skirt along a side edge of its bottom face, the corner bricks are laid at a corner part of the wall, and flat-bottom-type bricks are laid at a portion of the wall at least partially overlapping the corner bricks, said flat-bottom-type bricks having a configuration of said regular bricks from which said skirt is excluded.

7. A bricklaying method in which bricks and metal plates with bolt holes are alternately stacked and bolts extending through said bolt holes are securely tightened to vertically and integrally connect said bricks with each other, while imposing pre-stress on said bolts, comprising the steps of:

stacking corner bricks, each having a through-hole vertically extending therethrough with a diameter of said through-hole being larger than a diameter of said bolt holes, so that said bolt holes and said through-holes are vertically arranged in an alternate order; and

containing in said through-holes, nuts engageable with said bolts to securely tighten said corner bricks with said bolts and said nuts.

8. The bricklaying method as defined in claim 7 , wherein a straight wall is constructed by laying regular bricks, each regular brick having a raised center part on its top face and a skirt along a side edge of its bottom face, the corner bricks are laid at a corner part of the wall, and flat-bottom-type bricks are laid at a portion of the wall at least partially overlapping the corner bricks, said flat-bottom-type bricks having a configuration of said regular bricks from which said skirt is excluded.

9. The bricklaying method as defined in claim 7 , wherein said corner bricks are arranged in parallel in each step, with corner bricks that are vertically adjacent to each other being oriented at a right angle with each other, and said nuts contained in said through-holes of the corner bricks and the bolts inserted into said bolt holes of the corner bricks are connected with each other so as to make a columnar configuration.

10. A method of manufacturing a brick used for a bricklaying structure in which a plurality of bricks and metal plates are alternately stacked and fastening means extending through bolt holes of the bricks are securely tightened so as to connect the vertically adjacent bricks integrally under pre-stress of said fastening means, comprising:

forming a bolt hole vertically extending through the brick and two through-holes with the holes being spaced from each other on a longitudinal center line of the brick, said bolt hole having a first diameter for allowing a bolt of said fastening means to extend therethrough, said first diameter of said bolt hole being uniform throughout its height, and said through-holes having a second diameter for containing a nut of said fastening means engageable with said bolt, said second diameter of each through-hole being larger than said first diameter and uniform throughout its height.

11. The method of manufacturing a brick as defined in claim 10 , wherein said end faces of the brick are each provided with a vertical semicircular groove, and the groove provides a vertical channel in cooperation with a vertical groove of an adjacent brick, the channel having a diameter for containing said nut.

12. The method of manufacturing a brick as defined in claim 10 , wherein said bolt hole and said through-holes are formed such that a center of said bolt hole and centers of said through-holes are positioned on said center line, and these three centers and end faces of the brick are spaced an equal distance from each other, so as to be applicable to different architectural details of structure.

13. A bricklaying method comprising the steps of:

stacking bricks and metal plates with bolt holes alternately, each of the bricks having a through-hole vertically extending therethrough with a diameter of said through-hole being larger than a diameter of said bolt holes, so that said bolt holes and said through-holes are vertically alternately arranged;

extending bolts through said bolt holes and containing, in said through-holes, nuts engageable with said bolts; and

securely tightening said bricks with said bolts and said nuts to vertically and integrally connect said bricks with each other, while imposing pre-stress on said bolts.

14. The bricklaying method as defined in claim 13 , wherein end faces of the bricks are provided with a vertical groove in a form of a semicircle, a center of curvature of the groove being positioned on a longitudinal center line of said bricks, said vertical groove providing a vertical channel in cooperation with a vertical groove of an adjacent brick, the channel having a diameter for containing said nuts, and wherein said bolt holes and said channels are vertically alternately arranged.
