Block for constructions, panel for construction using the block, and method of forming panel for construction

Abstract

A block ( 10 ) for construction capable of constructing a flat structure by arranging the plurality of blocks in a flat state with four outer peripheral surfaces thereof, that are, an upper surface ( 10 a ), a lower surface ( 10 b ), a left side surface ( 10 c ), and a right side surface ( 10 d ) brought into contact with each other. In the block ( 10 ) for construction, a plurality of through holes ( 11 ) for inserting bar-like stretching members therein are formed parallel with the front surface ( 10 f ) and the rear surface ( 10 e ) thereof, and recessed parts ( 12 ) are formed in the upper surface ( 10 a ) and lower surface ( 10 b ) forming outer peripheral surfaces crossing the axial direction of the through holes ( 11 ) to dispose the other stretching members in a direction three-dimensionally crossing the stretching members inserted into the through holes ( 11 ). By using the block ( 10 ) for construction, the flat structures such as the wall parts and floor parts of a building can be easily constructed in a rather short period, and the durabilities of these flat structures can also be increased.
