Abstract:
1. A method implemented using a data processing system including a processor, a main memory, and a control program residing in the main memory, for planning an arrangement of bricks for the construction of a brick wall made by a dry type of construction method, in which the brick wall is constructed from bricks, bolts, nuts and metal plates and in which the bricks are integrally assembled under pre-stress by tightening forces of the bolts and nuts, wherein the brick has a planar dimensional proportion which is 1:2 in an aspect ratio, a bolt hole with a diameter smaller than an external diameter of said nut vertically extends through a center of a first square half part of said brick, a hollow section for containing the nut vertically extends through a center of a second square half part of said brick, and said bolt has an overall length for fastening the vertically adjacent two bricks, comprising the steps of: specifying a grid pattern XY coordinate system forming a number of square grid units, each of the grid units substantially conforming to a planar size of the square half part of said brick, and setting odd number layer tightening grids (α) and even number layer tightening grids (β) alternately in each of X- and Y-directions, using the data processing system; setting an arbitrary grid unit, to which an end part of the brick wall is allotted, to be a reference grid (γ), using the data processing system; positioning the brick of the end part of the brick wall on said reference grid for allocating the bricks in the odd number layer so as to match said first square half part to said odd number layer tightening grid, and successively arraying the bricks of the odd number layer from the brick on the reference grid, as well as positioning the brick of the end part of the brick wall on said reference grid for allocating the bricks in the even number layer so as to match said first square half part to said even number layer tightening grid, and successively arraying the bricks of the even number layer from the brick on the reference grid, using the data processing system; and arraying said metal plates for allocation of the plates on the bricks of said odd number layer so that at least one bolt hole of the plate is positioned on said odd number layer tightening grid, as well as arraying the metal plates for allocation of the plates on the bricks of said even number layer so that at least one bolt hole of the plate is positioned on said even number layer tightening grid, using the data processing system.
