Super unitized post tension block system for high high strength masonry structures—with SuperStrongBloks
View Patent ↗An improved, high strength construction system that uses post tensioning. It is comprised of a series of interconnected, super heavy duty hollow core blocks 102 with minimal ducts 103 , a series of tendons 105 , and a plurality of anchors or plates 104 with additional features. The system 101 is configured with the plurality of adjacent blocks 102 contiguous and touching one another and demountably coupled to each other by means of the tendons 105 and anchors 103 . The unique features include a strong, durable full plate 104 and bolt 105 both of which may be treated for corrosion resistance. This new coupling results in a structure that is far stronger than an ordinary block structure built with mortar and standard reinforcing. The SYSTEM has more predictable and controlled strength which is stronger than most reinforced concrete systems.
1. An assembly, comprising:
first, second and third respective parallel, stacked anchor plates, each respective plate having a respective first aperture and a respective second threaded aperture;
a first concrete block disposed between the first and second anchor plates;
a second concrete block disposed between the second and third anchor plates;
a first post extending through the first concrete block and engaged to the respective first aperture in the first anchor plate and threadedly engaged with the respective second threaded aperture in the anchor second plate;
a second post extending through the second concrete block and engaged to the respective first aperture in the anchor second plate and threadedly engaged with the respective second threaded aperture in the anchor third plate;
wherein threaded engagement of the first post with the respective second threaded in the first plate aperture exerts a tensile force on the first post and a compressive force on the first concrete block;
wherein threaded engagement of the second post with the respective second threaded aperture in the second plate exerts a tensile force on the second post and a compressive force on the second concrete block;
wherein the second anchor plate is compressively connected to the first and second blocks;
wherein a line passing through a respective first and second aperture intersects a side of the anchor plate at a 45 degree angle; and
wherein each anchor plate further includes demarcations commensurate with the orientation of each respective first and second aperture.
2. A high strength masonry structure comprising:
a plurality of respective masonry units, each respective unit having parallel top and bottom planar surfaces defining a standard distance therebetween, and first and second respective cavities, each respective cavity extending from the top to the bottom surface;
a plurality of respective anchor plates, each respective anchor plate having a first and a second pair of apertures, each respective pair of apertures including a respective nonthreaded aperture and a respective threaded aperture, and each respective anchor plate positioned adjacent a respective top planar surface, wherein a respective first set of apertures is aligned with a respective first through-cavity and a respective second set of apertures is aligned with a respective second through-cavity;
a plurality of respective tensioning posts, each respective tensioning post having a respective head portion at a respective top end and a respective threaded portion at a respective bottom end and defining a post length therebetween, wherein the post length is greater than one standard distance but less than two standard distances;
wherein each respective post extends through a first respective anchor plate, a through cavity, and a second respective anchor plate, with the respective head portion engaging the first respective anchor plate at an unthreaded aperture and the respective threaded portion threadedly engaging the second respective anchor plate at a threaded aperture to define an engaged post;
wherein each respective masonry unit is operationally connected to at least one other respective masonry unit by at least one respective anchor plate;
wherein each respective threadedly engaged post applies a compressive force to a respective masonry unit to define a respective compressed masonry unit;
wherein each respective compressed masonry unit is operationally connected to at least one other compressed respective masonry unit by at least one respective anchor plate;
wherein the respective operationally connected compressed masonry units define a post tensioned structure;
wherein a first line passing through a respective pair of apertures intersects a side of the anchor plate at a 45 degree angle;
wherein the each respective first pair of apertures enjoys an orientation that is reversed relative to each respective second pair of apertures;
wherein a second line passing through the respective second pair of apertures would be orthogonal to the first line; and
wherein each anchor plate further includes demarcations commensurate with the orientation of each respective first and second pair of apertures.
