Abstract
A building has walls built from blocks with cavities. Roofs and floors are formed from joists extending between walls. Each joist has a vertical plate, an angle piece located on each side of the vertical plate and end plates. The end plates bear on the wall blocks. Pins extend from the end plates into cavities of the wall blocks. Bond beams can be positioned on walls parallel to the joist. Horizontal blocks are laid across the joists to form a roof or floor.
Claims27
A building having at least two parallel walls made of stacked blocks, the blocks having cavities therein, which cavities are aligned vertically, the building having a horizontal roof or floor, comprising:
- a) joists spanning between the two walls, with each joist made from a vertical plate with an upper portion and at least one angle piece, the angle piece having a first portion and a second portion, the first portion coupled to the upper portion of the vertical plate, the second portion extending laterally from the first portion and the vertical plate, the vertical plate having a thickness, each joist having two ends and having a longitudinal direction between the two ends, each joist having a width which comprises the thickness of the vertical plate and a lateral extension of the angle piece;
- b) each end having a horizontal end plate coupled thereto and extending longitudinally from the respective end, the end plate having a width that is wider than the width of the combined angle piece and the vertical plate;
- c) one of the joists is a first joist, another of the joists being a second joist that is adjacent to the first joist, the end plates of the first joist being separate from the end plates of the second joist;
- d) each of the end plates having at least one pin extending vertically down, the pin located in a block cavity in the wall, the end plates located on the respective walls;
- e) horizontal blocks located on top of the joists, the angle piece and the end plates forming a top surface.
A building having at least two parallel walls made of stacked blocks, the blocks having cavities therein, which cavities are aligned vertically, the building having a horizontal roof or floor, comprising:
- a) joists spanning between the two walls, with each joist made from at least one angle piece, the angle piece having a vertical portion and a horizontal portion, the horizontal portion extending laterally from the vertical portion, the vertical portion depending down from the horizontal portion, each joist having two ends and having a longitudinal direction between the two ends, each joist having a width which comprises the lateral extension of the horizontal portion;
- b) each end having a horizontal end plate coupled thereto and extending longitudinally from the respective end, the end plate having a width that is wider than the width of the joist;
- c) one of the joists is a first joist, another of the joists being a second joist that is adjacent to the first joist, the end plates of the first joist being separate from the end plates of the second joist;
- d) each of the end plates having at least one pin extending vertically down, the pin located in a block cavity in the wall, the end plates located on the respective walls;
- e) horizontal blocks located on top of the horizontal portions of the first and second joists and the end plates forming a top surface, each of the horizontal blocks having ends and sides, with the distance between the ends being a horizontal block length and the distance between the sides being a horizontal block width, the horizontal block length being greater than the horizontal block width, the horizontal blocks arranged in an end-to-end manner so that one of the ends of one of the horizontal blocks contacts an adjacent horizontal block.
