Keel connecting device of steel aluminum frame template

The utility model discloses a keel connecting device of a steel aluminum frame template. The steel aluminum frame template comprises a template body and a steel aluminum frame supported on the template body, a first keel is arranged on the outer side of the steel aluminum frame in the first direction, a second keel is supported on the outer side of the first keel in the second direction perpendicular to the first direction, and the keel connecting device comprises a support and an abutting part. A hooking part is arranged on the side portion of the support, a hooking portion is formed at the end of the hooking part, and the hooking portion is hooked on the first keel in the connection process of the second keel; the abutting part penetrates through the support and abuts against the second keel in the connection process of the second keel. According to the keel connecting device of the steel aluminum frame template, the hooking part is hooked on the first keel, pull force is exerted on the first keel in the first direction, then abutting force is exerted on the second keel in the second direction opposite to the first direction by adjusting the abutting part, and therefore the second keel and the first keel are fastened. The device has the advantages of being simple in structure, capable of being repeatedly used and the like.
