Abstract: An extension type balcony bracket and a construction method of an extension type balcony bracket are provided to prevent the human damage caused by an accidental fall of an extension type balcony bracket, to secure safety at installation and dismantlement works of a fall prevention net by having a bracket supporting a fall prevention net integrally and installing and dismantling the bracket easily, and to perform balcony installation work effectively. An extension type balcony bracket includes an upper bracket(20) formed on internal and external walls(4,5) and a window projection(2) of a balcony at the upper floor of a building and provided with a compressor(6) formed to compress the internal wall of a balcony, a screw hole(11) formed on the lower part of a fastener(7) to move the compressor forward and backward, a through hole(9) formed on the top of the fastener to fasten a fixing bolt(8), an insertion hole(12) formed on one side of a support plate(15) to insert the fixing bolt coupled to the through hole, a support fixture(14) formed on the other side of the support plate to fix a support(13) mounted with a fall prevention net and a chain(17) welded to one side of a bracket(16) welded to the bottom of the support plate to prevent the movement of the support, and a lower bracket(30) formed on internal and external walls(4a,5a) and a window projection(2a) of a balcony at the lower floor of a building and provided with a compressor(6a) formed on the lower part of a fastener(7a) to compress the internal wall of a balcony, a screw hole(11a) formed on the lower part of the fastener to move the compressor forward and backward, a through hole(9a) formed on the top of the fastener to fasten a fixing bolt(8a), a bracket coupled with a support plate(15a) provided with an insertion hole(12a) fitted with the fixing bolt to couple with the through hole formed on the top of the fastener, a support holder(21) formed in the bracket to insert the support supporting the fall prevention net, pin holes(22,23) formed on the outer top of the bracket to prevent the support inserted to the support holder from overturning forward or backward and a hook(25) formed on the top of the bracket to fix a wire of the fall prevention net. A construction method of an extension type balcony bracket comprises the steps of: installing an upper bracket to internal and external walls and a window projection of a balcony easily by inserting a fixing bolt to a through hole formed on the upper part of a fastener formed on one side of an upper bracket and an insertion hole formed on a support plate welded to a bracket formed on the other side of the upper bracket; and installing a lower bracket to internal and external walls and a window projection of a balcony simply by inserting a fixing bolt to a through hole formed on the upper part of a fastener formed on one side of a lower bracket and an insertion hole formed on a support plate welded to a bracket formed on the other side of the lower bracket.
