Superaltitude conversion truss lifting device
The invention belongs to the field of constructing steel structures in civil building structures, and particularly relates to a superaltitude conversion truss lifting device which comprises an upper lifting device and a lower lifting device. The upper lifting device is characterized in that two ends of an upper lifting beam and two ends of a lower lifting beam are connected with a lifting beam fixing piece respectively, and an upper reserved hole is formed in each of the two ends of the upper lifting beam; the lower lifting device is characterized in that a lower reserved hole is formed in each of the two ends of the lower lifting beam, the upper reserved holes correspond to the lower reserved holes in position, and both the upper lifting beam and the lower lifting beam are perpendicularly connected onto a truss chord member through the lifting beam fixing pieces. The superaltitude conversion truss lifting device is small in size and light in weight and has no influence on the structure of a truss; the superaltitude conversion truss lifting device can be adjusted through the fixing pieces according to the size of the truss chord member, so that the applicable range of the superaltitude conversion truss lifting device is widened; a stressed reinforcing board is added at a lifting position inside each lifting beam, so that position strength of a positioning point is guaranteed; the superaltitude conversion truss lifting device is independently separated from the truss, thereby being capable of being mounted and demounted conveniently and high in practicability.
