Home on hill with clouds -- Chicken Coop??3480 viewsUpper Left --this is a finished dome. The inner wall void was filled with about 8 yards of cellular concrete and was filled through a small hole in the top of this dome. The doors and window are an EPS sandwich over tempered glass scrap pieces and reinforced in the middle and on the surface with fiberglass mesh and a high strength acrylic modified cement mix called Dryvit Primus. The door and windows are solid, light, slightly flexible, very insulating and easy to build.

Upper Right -- This illustrates several phases. You can see the electrical conduit mounted with-in the remesh block matrix. Mounting electrical and plumbing in this skeleton armature makes life easy for the electrition and plumber.

Middle and Bottom Left -- The armatures for these nesting pods and railings were sculpted from just expanded metal plaster lath. The concave shapes were done by cutting snips out of the square lath and then closing the gap with wire. Just made a pile of these dish shaped pieces of lath and put them together. The railing is just a crumpled piece of lath with fiber glass mesh on the top side but just in the tensil weak points.

Bottom Right -- This is what the armature looks like after the lath is sewed onto the remesh block armature.

Folder Apperatus in Action2325 viewsDoug Smith is placing the holder foot onto a length of steel for folding. The holder is lock into place by sliding under the two bolts on the center stationary portion of the folder. Although this rig is set up for doing 6 inch wire blocks, repositionin the foot an extra time to do 12 inch by 5 foot blocks turned out to not cost extra time.

park glass wall.jpg
Fluid Shape2838 viewsThis wall was filled with 25 tons of glass before the surface shells were applied. The nice distortions on the surface were caused by heavy glass getting stuck on the remesh blocks that were layed in laterally instead of vertically. The lateral blocks restricted the size of the openings for the glass to fall and the armature bowed outward under the weight because their were long horizontal runs that had no cross tension supports. All good though. This wall is now the focus of a big mural project.

Hinge Pin Hardware Mounting3055 viewsThis form enabled the hinge pin for this gate to be burried in 6 inches of high-strength concrete. A tension metal wire ties the end of the pin down to provide extra reinforcing.

Nicho3209 viewsThese Nicho's Provided stability but it should not be assumed that plastering the underside of these is quick and easy for a plaster crew. The topside portion of these details should be plastered by reaching inside the wall through an opening.Jul 12, 2006
