Abstract
Abstract A building construction of the type using prefabricated reinforced concrete panels for the internal and external walls and the flooring is provided with a concrete foundation having a sole-piece on which are mounted a plurality of supporting blocks having recesses in which the first level of panel walls are mounted. The panels are positioned in the supporting blocks by pins extending between aligned holes in the recesses and the panels. At their other ends the panels are provisionally connected together by connecting means of various configurations depending on what combination of panels are connected together. Spaces are maintained between adjacent panels into which concrete is poured to make the connection permanent. Additional stories may be added by pins connected between the wall panels of wall panels of adjacent levels. Various seals may be provided between the panels for weather protection and for preventing the escape of concrete during pouring.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A building construction comprising prefabricated rectangular concrete panels juxtaposed in edge to edge relationship along their vertical edges, spaced blocks, each block supporting a pair of said panels adjacent their vertical edges, each block having channels on its upper surface, each channel having a bottom and side walls and receiving a panel, vertically extending holes in the bottom of said channels, pins extending between said holes and the bottoms of said panels, vertically extending flange means on said panels forming recesses between adjacent panels to receive poured concrete, and horizontally extending flanges on the upper edges of said panels extending from one vertical edge to the other of each of said panels to form a horizontally extending recess for the reception of poured concrete, and tie members positioned in said horizontal recess to hold the upper portions of said panels in position, each tie member comprising vertically extending pins received in holes in the upper edges of said panels and a horizontal member joining said vertical pins and bridging the vertical joint between said panels.
Claim 2
Dependent Claim
175 words
A building construction comprising prefabricated rectangular concrete panels juxtaposed in edge to edge relationship along their vertical edges, spaced blocks, each block supporting a pair of said panels adjacent their vertical edges, each block having channels on its upper surface, each channel having a bottom and side walls and receiving a panel, vertically extending holes in the bottom of said channels, pins extending between said holes and the bottoms of said panels, vertically extending flange means on said panels forming recesses between adjacent panels to receive poured concrete, and horizontally extending flanges on the upper edges of said panels extending from one vertical edge to the other of each of said panels to form a horizontally extending recess for the reception of poured concrete, and tie members positioned in said horizontal recess to hold the upper portions of said panels in position, each tie member comprising vertically extending pins received in holes in the upper edges of said panels and a horizontal member joining said vertical pins and bridging the vertical joint between said panels.
Claim 3
Dependent Claim
72 words
A building construction as claimed in claim 1, wherein horizontally extending reinforcing rods in each of said panels have end portions extending into said recesses and a pair of indentations in the vertical edges of each panel is adjacent the end of each reinforcing rod, one indentation being above a rod and the other below a rod, said reinforcing rods and indentations acting to rigidly key the panels to the poured concrete.
Claim 4
Dependent Claim
33 words
A building construction as claimed in claim 2, wherein each indentation is formed as an irregular pyramid, the faces of said pyramids forming supporting surfaces for the panels relative to the poured concrete.
Claim 5
Dependent Claim
54 words
A building construction as claimed in claim 1, wherein the horizontally extending flanges are on the exterior of said panels, the body portions of said panels form a ledge receiving the edges of floor panels and vertical pins extend between the horizontally extending flanges and other prefabricated concrete panels above said first mentioned panels.
