The present invention provides a device without blocking wireless signals based on impedance matching. The device is constructed by periodically stacking two building materials with different dielectric constants in the same direction. The device without blocking wireless signals based on impedance matching can be designed as a wall body, and can improve wave transmission of microwaves to ensure that wireless signals won't be blocked at any incident angle, thereby achieving the unblocked transmission of wireless signals. Furthermore, compared with metal hole arrays, the component materials of the devices can include polypropylene and concrete, that expands the applications from micro circuit electronic devices to macro walls, and greatly reduces the manufacturing and maintenance cost.

A construction block system including primary blocks 15, primary half blocks 115, base blocks 215, base half blocks 315 and column blocks 415 that cooperate to erect vertical structures using leveling and alignment tools at the base and between rows of blocks. Alignment and leveling tool 80 permits the leveling of the first row with respect to a supporting surface S and also immobilizes tool 80. The longitudinal outer walls 20; 40; 120; 140; 220; 240; 320; 340; 420 and 440 include outwardly extending rectangular walls 25; 45; 125; 145; 225; 245; 325; 345; 425; and 445 that coact with each other leave a space between abutting blocks for cementitious substances to further bind the structure. Tool 80 rests on surface S and includes two parallel rails receivable within cooperating and aligned channels on the base and column blocks. Tools 80 includes an elongated rigid member receivable within abutting blocks horizontal surfaces and serves to align and strengthen the structure.

A concrete wall pre fabrication for the easy assembly of walls for residential and commercial buildings. More specifically, there is an apparatus and method for enabling the outer form of a concrete wall to be more precisely assembled off site and then transported to the work site and assembled the wall in the proper place with appropriate rebar before filling the forms with cement or concrete material as disclosed in the specification and drawings of the invention and the related claims. Additionally, there is a need for a form spacer that efficiently attaches between the form walls with a more precise use of glue and stronger attachment to the form walls.
