Abstract
The utility model belongs to the technical field of building temporary support fixing, and particularly relates to a building temporary support adjustable fixing device which comprises two cross-shaped fasteners, each cross-shaped fastener comprises an upper half portion and a lower half portion, and the other end of each upper half portion and the other end of each lower half portion are connected with a first connecting piece and a second connecting piece respectively. Fasteners are arranged in the first connecting piece and the second connecting piece; the fastener comprises a threaded column, four movable arms are hinged to the lower end of the threaded column, barbs are arranged at the lower ends of the four movable arms, first threads are arranged on the outer wall of the threaded column, a circular through hole is formed in the middle of the threaded column, second threads are arranged in the circular through hole, the outer wall of the threaded column is in threaded connection with a first nut, and a bolt is in threaded connection with the interior of the threaded column. A pushing block is movably arranged at the lower end of the bolt and provided with a second nut. According to the cross fastener, the locking piece can be directly inserted into the round holes in the upper half part and the lower half part, and then the cross fastener can be fastened by directly using an electric wrench.
