Stepped closure for duct coupling

Abstract

A concrete block assembly with crenellations making space for a user to interact with a duct assembly running through the block.

What is claimed is: 
     
         1 . A reinforced concrete block assembly comprising:
 one or more concrete blocks each having a substantially rectangular body, wherein each body comprises a hollow space extending along a longitudinal axis of the body;   wherein each concrete block further comprises:   a first side with a crenellation pattern, wherein the crenellation pattern comprises a series of merlons and embrasures, wherein the merlons extend outwardly from the first side;   a second side opposite the first side, wherein the second side comprises openings aligned with the hollow space; and   at least one duct disposed within the hollow space and extending through the openings on the second side, wherein the at least one duct is configured to receive one or more tendons;
 wherein the crenellation pattern is configured to mate with a corresponding crenellation pattern of a subsequent concrete block assembly when arranged adjacent thereto, such that the merlons of a first concrete block align with the merlons of a concrete block, thereby forming an open space between the concrete blocks for facilitating installation and manipulation of the at least one duct and tendons. 
   
     
     
         2 . The assembly of  claim 1 , wherein the concrete block further comprises reinforcing materials selected from the group consisting of steel bars, mesh, and fibers embedded within the concrete body. 
     
     
         3 . The assembly of  claim 1 , wherein the merlons extend outwardly from the first side of the concrete block at a length ranging from 10% to 50% of the width of the concrete block. 
     
     
         4 . The assembly of  claim 1 , wherein the crenellation pattern further comprises decorative features selected from the group consisting of grooves, ridges, and ornamental designs. 
     
     
         5 . The assembly of  claim 1 , wherein the at least one duct further comprises a corrosion-resistant material selected from the group consisting of stainless steel, plastic, and coated materials. 
     
     
         6 . The assembly of  claim 1 , wherein the open space formed between the first and second concrete block assemblies is adaptable to accommodate additional functional elements selected from the group consisting of utility conduits, communication cables, and sensors. 
     
     
         7 . The assembly of  claim 1 , wherein the concrete block is manufactured using a precast molding process. 
     
     
         8 . The assembly of  claim 1 , wherein the concrete block further comprises additives selected from the group consisting of fly ash, slag, and silica fume, to enhance the durability and sustainability of the assembly. 
     
     
         9 . The assembly of  claim 1 , wherein the second side of the concrete block comprises reinforcing elements configured to secure the at least one duct in place. 
     
     
         10 . A reinforced concrete block assembly comprising:
 a concrete block having a body, wherein the body comprises a hollow space extending along the body;   wherein the concrete block further comprises:   a first side with a crenellation pattern, wherein the crenellation pattern comprises one or more merlons and embrasures, where the merlons extend outwardly from the first side;   a second side opposite the first side, wherein the second side comprises openings aligned with the hollow space; and   at least one duct disposed within the hollow space and extending through the openings on the second side, where the at least one duct configured to receive tendons;   wherein the crenellation pattern is configured to mate with a corresponding crenellation pattern of a second concrete block assembly when arranged adjacent thereto, such that the merlons of the first concrete block assembly align with merlons of the second concrete block assembly, thereby forming an open space between the first and second concrete block assemblies.   
     
     
         11 . The assembly of  claim 10 , wherein the open space between the first and second concrete block assemblies facilitates installation and manipulation of the at least one duct and tendons. 
     
     
         12 . The assembly of  claim 10 , wherein each concrete block further comprises reinforcing materials selected from the group consisting of steel bars, mesh, and fibers embedded within the concrete body. 
     
     
         13 . The assembly of  claim 10 , wherein the merlons of adjacent concrete structures interlock to provide enhanced stability and load distribution between the concrete structures. 
     
     
         14 . The assembly of  claim 10 , wherein each concrete block further comprises a plurality of ducts arranged in a parallel configuration within the hollow space. 
     
     
         15 . The assembly of  claim 10 , wherein the at least one duct within each concrete block further comprises a central void, facilitating the passage of additional elements therethrough. 
     
     
         16 . The assembly of  claim 10 , wherein each concrete block is manufactured using a precast molding process. 
     
     
         17 . The assembly of  claim 10 , wherein the second side comprises a second crenellation pattern configured to mate with a corresponding crenellation pattern of a subsequent concrete block assembly when arranged adjacent thereto. 
     
     
         18 . The assembly of  claim 10 , wherein the assembly forms a load-bearing wall system, capable of supporting vertical and lateral loads while accommodating services and utilities. 
     
     
         19 . The assembly of  claim 10 , wherein the concrete block has at least one selected from the group of a rectangular body and a square body. 
     
     
         20 . A concrete block assembly comprising:
 a concrete block having a rectangular body, wherein the body comprises a hollow space extending along a longitudinal axis of the body, wherein the hollow space is configured to receive at least a duct;   the concrete block further comprising:   a first side with a crenellation pattern, the crenellation pattern comprising one or more merlons and one or more embrasures, wherein the merlons extend outwardly from the first side;   a second side opposite the first side, wherein the second side comprises openings aligned with the hollow space; and   wherein the crenellation pattern is configured to mate with a corresponding crenellation pattern of a second concrete block assembly.
