Title: the block for a building with the binding structure
Inventor: LEE JONG HA
IPC: E04B2/02
Filed: 2018-10-04
Abstract: The present invention relates to a binding structure applied to a prefabricated wall block having an uneven portion in upper and lower portions to be constructed in a prefabrication manner and, more specifically, to a prefabricated wall block of a known structure having a binding recess portion and a protrusion portion in upper and bottom portions. In the binding structure, a pair of inwardly recessed insertion grooves are formed in each of the binding recess portion and the protrusion portion so as to face each other. When the wall blocks are constructed by using binding bars inserted into the insertion grooves, upper and lower wall blocks are integrally bound and supported through the binding bars. The wall blocks bound through the binding bars are completely prevented from moving in longitudinal and transverse directions, thereby enhancing the bonding force between the constructed blocks. Accordingly, support strength against longitudinal and transverse pressures applied to the wall can be significantly increased, thereby enhancing strength and seismic resistance of the entirety of the building. The binding bars enable precise assembly between the blocks without gaps, thereby eliminating the need for application of separate bonding mortar to improve workability.
