A mortarless block system for forming walls from blocks which are stackable in sequential rows upon each other. Upper rows of blocks positioned upon lower rows are securable by positioning of support rods through aligned passages thereof. The passages extend between upper and lower notches in each respective block. The support rods are engaged to connectors which are sized to fit completely within the notches to thereby leave the upper and lower surfaces of each lower row flush to stacking overhead rows thereon.

An experimental system for out-of-plane seismic performance of a masonry block wall, comprising: a static test bed (1), a lateral limiting system disposed on one side on the static test bed (1), and a transverse load system disposed on the other side on the static test bed (1), a masonry block wall to be tested (401) being disposed between the lateral limiting system and the transverse load system. The experimental system also comprises a vertical load system disposed above a wall. Also provided is an experimental method using the experimental system for out-of-plane seismic performance of a masonry block wall, on the basis of a quasi-static test method, a horizontal reciprocating actuator is used to simulate an out-of-plane seismic load action; quarter-point loading is implemented by means of a multi-stage shear stress distribution apparatus, then a force is transmitted to a second screw rod (602), and the second screw rod (602) fits an out-of-plane uniformly distributed load into four horizontally-equidistant transversely-concentrated forces and transmits same to a test piece. The present invention has the characteristics of a clear force transmission path, uniform stress distribution, high experimental precision and an accurate result, such that the study of the out-of-plane seismic performance of a component is more accurate and reliable.

The primary objective of the present invention is to provide an interlocking, interchangeable wall system allowing for the formation of a plurality of form structures. Each parallel sidewall is embedded with stones or other materials into a composition base on one side. On the opposite side, the sidewalls are embedded with metal lathing and hardware to connect to bracing which connects to the opposing sidewall to form a plurality of structures, including an interlocking block system. Each sidewall interlocks with the panel or block next to it. When connected, the resulting interlocking composite blocks may be used in the construction of walls or other structures. The resulting sidewalls may be used in the decoration of existing construction or other structures. The present invention provides a significant improvement in labor and customization of structures.

A mortarless block system for forming walls from blocks which are stackable in sequential rows upon each other. Upper rows of blocks positioned upon lower rows are securable by positioning of support rods through aligned passages thereof. The passages extend between upper and lower notches in each respective block. The support rods are engaged to connectors which are sized to fit completely within the notches to thereby leave the upper and lower surfaces of each lower row flush to stacking overhead rows thereon.
