Concrete joint inserter tool

Abstract

A concrete crack control joint insertion tool to insert joint forming materials into a concrete mixture or alternatively providing means to create a crack control joint without the use of ancillary material. Crack control joint in fresh concrete is formed beneath a rectangular structure supporting linear actuators that drive a blade alone or carrying joint forming materials into a precise location and depth. Crack control joint formation is repeatable completed in a single motion and with continued precise accuracy of placement.

1 ) A Concrete Joint Inserter Tool used to form crack control joints in concrete comprising:
 a Structural members directing the insertion action of joint forming material.   b Structural members providing mounting for mechanical means of inserting joint forming material into a concrete mixture.   c Linear actuators providing forces necessary to insert joint forming material into a concrete mixture.   d Electrical, pneumatic and/or hydraulic controls providing means to manage the process to insert joint forming material into a concrete mixture.   
     
     
         2 ) A Concrete Joint Inserter Tool of  claim 1  which provides means to install joint forming material into a concrete mixture at a selected depth. 
     
     
         3 ) A Concrete Joint Inserter Tool of  claim 1 , which provides means to install joint forming material of selected length into a concrete mixture. 
     
     
         4 ) A Concrete Joint Inserter Tool of  claim 1  which provides means to install joint forming material into a concrete mixture with a single mechanical motion, completing in one action the creation of a crack control joint. 
     
     
         5 ) A Concrete Joint Inserter Tool of  claim 1  which provides means to install precisely placed joint forming material, repeatedly such that no further action is required in completing the joint. 
     
     
         6 ) A Concrete Joint Inserter tool of  claim 1  of mechanical configuration that allows its size, dimension and format to be altered as necessary to accommodate future development of joint forming materials. 
     
     
         7 ) A Concrete Joint Inserter Tool used to form crack control joints in concrete without the use of joint forming material. Comprising:
 a Structural members directing the insertion action of a joint forming blade.   b Structural members providing mounting for mechanical means of inserting a joint forming blade into a concrete mixture.   c Linear actuators providing forces necessary to insert a joint forming blade into a concrete mixture.   
     
     
         8 ) A Joint Inserter tool of  claim 7  which provides means for inserting a joint forming blade into a concrete mixture at a selected depth. 
     
     
         9 ) A Concrete Joint Inserter tool of  claim 7  which provides means to insert a joint forming blade of selected length into a concrete mixture
 a A Concrete Joint Inserter tool of  claim 7  which provides means to insert a joint forming blade into a concrete mixture with a single mechanical motion, completing in one action the development of a crack control joint. 
 
     
     
         10 ) A Concrete Joint Inserter tool of  claim 7  which provides means to insert a joint forming blade precisely placed, repeatedly such that no further action is required in completing a crack control joint.
