Description
Technical Field
The invention belongs to the technical field of constructional engineering, and particularly relates to a spatial vertical rotation construction method for a steel structure roof of a large-scale venue.
Background
In recent years, with the gradual expansion of the functions of large-scale stadiums from the basic requirements, the steel structure roof has the characteristics of complex structure types, novel modeling, large component size, large structural span, ultrahigh installation height and the like. At present, the common construction methods for mounting the steel structure roof of the large-scale venue comprise a high-altitude bulk mounting method, a strip or block mounting method, a high-altitude sliding method, an integral hoisting method, an integral lifting method, an integral jacking method and the like.
The high-altitude bulk method is a method for directly and totally assembling small units or parts (single rod piece and single node) at a designed position, is suitable for various types of net racks with bolted joints, and is particularly suitable for the situation of difficult lifting.
The strip or block mounting method is a mounting method that the net rack is divided into strip or block units which are respectively hoisted to a high-altitude design position by hoisting equipment to be placed in place and then form a whole. The method is suitable for the net racks with small changes of rigidity and stress conditions after division, such as net racks with two-direction orthogonal square pyramid, positive evacuation square pyramid and the like. The mounting method is beneficial to improving the engineering quality and can save most of the assembly supports.
The high-altitude sliding method is an installation method for splicing the split net rack units into a whole by sliding the split net rack units to a designed position on a preset slide rail one by one. The method is suitable for the net racks such as an upright square pyramid, an upright evacuated square pyramid, a two-direction orthogonal square pyramid and the like. The sliding unit is guaranteed to be a geometric invariant system during sliding.
The integral hoisting method is a construction method that after the net racks are assembled on the ground, the net racks are hoisted in place by hoisting equipment. The welding work of the integral net rack is carried out on the ground, the construction quality is better ensured, the method is suitable for various net racks, and the net racks can be horizontally moved or rotated to be in place at high altitude during hoisting.
The integral lifting method is a construction method for mounting lifting equipment on a structural column and lifting a net rack spliced on the ground in place. The net rack integral lifting method can structurally install a lifting device to lift the net rack, and can also lift the net rack when the sliding formwork construction of the column is carried out. It is suitable for peripheral support and multi-point support net frame, and can be constructed by small machines such as plate-lifting machine and hydraulic jack.
The integral jacking method is a lifting method that the net rack is assembled into a whole on the ground at a designed position and then jacked to a designed height by a jack. It is suitable for multi-point supporting net frame with less supporting points.
In conclusion, the high-altitude bulk mounting method is to perform total assembly at a design position, the high-altitude sliding method is to perform accumulated sliding assembly at a design elevation, both the two mounting modes need to arrange a large number of supporting jig frames, the high-altitude welding amount is large, the high-altitude hoisting workload is large, the requirement on precision control is high, and a large amount of manpower, machines and tools are often invested due to the limitation of a construction period, so that the construction quality and the construction safety are difficult to guarantee. The strip or block mounting method and the integral hoisting method refer to hoisting the assembled unit to a designed position by means of hoisting equipment, the two mounting methods are often influenced by the hoisting capacity and hoisting range of the hoisting equipment, and meanwhile, the hoisting capacity of the hoisting equipment is supplemented with the self weight, so that the requirement on the bearing capacity of the walking track is high. While the integral lift method and the integral jacking method are generally applicable to regular multi-point support net frames, the integral jacking method is also affected by the stroke of the jacking equipment.
Aiming at large steel structure roofs of large size, heavy weight of rod pieces, large structural span and ultrahigh installation height of large stadiums, especially huge ribbed space folded plate-shaped grid structures, the installation requirements of the steel structure projects are difficult to meet by using the existing steel structure roof installation method.
