According to the latest regulation of JGJ/T187-2009, the installation of the standard knot at the upper part of the tower crane can be started when the strength grade of the concrete of the tower crane foundation reaches 80% of the design strength, and the tower crane can be hoisted when the strength grade of the concrete reaches 100% of the design strength. At present, a reinforced concrete foundation is adopted in a construction site, but the construction is difficult in areas where a newly-built building contains a basement garage, the excavation depth of a foundation pit is deep, the underground water level is high, and quicksand is more. Compared with a reinforced concrete foundation, the newly-appeared tower crane steel platform foundation has great advantages, including short period from construction to use; the foundation stress is clear, safe and reliable; the dismounting is convenient and the reuse can be realized; the economic effect is obvious. Along with the increase of the service time of the on-site tower crane steel platform, the daily maintenance and overhaul of the steel platform become an indispensable link. In order to strengthen the safety protection measures during daily maintenance, installation and maintenance, steel pipes are adopted to set up maintenance platforms and handrails on a plurality of construction sites, and the steel pipes are fully paved with boards. However, the protection mode has the defects of instable erection, easy falling of the springboard, serious potential safety hazard, more installation parts, large difficulty in installation and disassembly, time and labor waste in installation and construction, difficult reuse and waste of a large amount of materials.
SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model discloses a technical scheme as follows:
an assembly type tower crane maintenance platform comprises four lattice columns positioned at four corners, wherein each lattice column is fixedly connected with triangular supports on two outer side surfaces respectively, all the triangular supports fixedly connected with the four lattice columns are positioned at the same height,
two parallel channel steels are respectively fixedly connected between the two triangular supports positioned at the same side, the channel steels on all the triangular supports are mutually welded into a whole,
and the channel steel is provided with a socket type disc buckle type steel pipe scaffold and a steel stair.
Further, the triangular supports are formed by welding horizontal channel steel and oblique channel steel, horizontal connecting steel plates and oblique connecting steel plates are welded at the joints of the corresponding triangular supports of the lattice columns respectively, and the horizontal channel steel and the horizontal connecting steel plates, and the oblique channel steel and the oblique connecting steel plates are connected through high-strength bolts.
Further, the included angle between the oblique channel steel and the lattice column is 45 degrees.
Further, the channel steel adopts 8 # channel steel, and the triangular supports are made of 16# A # channel steel.
