Benefits of technology

[0009]The wall blocks may be designed for a particular application, or inventories may be maintained of standard wall lengths and features such as door and window locations. In one embodiment, a tongue and groove base key detail supports the stacking of wall blocks for multi-level construction. Only the first block installed at each level in an assembly should require any temporary bracing, and each subsequent block enjoys immediate stability when the pin is installed.

Problems solved by technology

These systems have the disadvantage of shoring requirements and limited stability until the cast-in-place joints have been placed and the concrete allowed time to gain strength.
These prior art systems are inefficient in the utilization of costly crane time, and rigidly welded joints tend to perform poorly in the presence of the thermal movements that affect all structures.

example

[0108]Where the offset of an architectural facade such as between blocks 630 and 631 of FIG. 38; or an interior wall such as blocks 632 and 633 is on the order of a single wall thickness, a variation of the finger joint can offer a solution. The pair of walls in FIG. 38 that point to the left each offer a finger pattern B for the forward wall, and also offer double pins and two double-width receivers to accommodate two fingers from a center wall that is inset by one wall thickness as shown in FIG. 39.

Finger Floor Block System

[0109]The ledge examples described in FIG. 11B above showed a 30 cm (12 in.) thick wall that could offer a 10 cm wide ledge 410 either side of a 10 cm keyed continuous plinth 200. This application also envisions a 20 cm (8 in.) or thinner wall that can carry floor on one or both sides and stack to build multi-story construction. The thinner walls feature full-width bearing ledges at interior bearings and half-width ledges at perimeter bearings, and they show a p...

Abstract

Precast planar construction wall blocks are provided with various configurations of fingers. Structures are rapidly assembled by aligning the fingers and inserting a pin through vertical sleeves provided in the fingers. Finger joints are typically shimmed and grouted for additional strength. Openings for doors and windows are provided in some wall blocks. Floor blocks are supported on ledges at the top of wall blocks or by portions of the top edges of wall blocks. A concrete or other topping may be added to floor blocks, and conduit may be run in the topping.
