Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses an inner ring opening string roof beam hoisting structure, including last chord 51, cable vaulting pole 53 and supplementary rigging, cable vaulting pole 53 has many, and cable vaulting pole 53 upper end is connected with last chord 51, and cable vaulting pole 53 lower extreme is used for being connected with the cable.
The number of the stay rods 53 is set as required, and the stay rods 53 serve to provide an elastic support for the upper chord 51. In general, as the number of stay stays 53 increases, the bending moment and shearing force of the upper chord 51 gradually decrease. But the improvement of the member force is not significant when the number of the stay rods 53 is increased to a certain number. In the present embodiment, the stay rods 53 are spaced apart by 6 m.
In the present embodiment, the upper boom 51 is hoisted by using an auxiliary hoist including a carrying pole 9, two wire ropes 101 connected to the carrying pole 9, and at least two slings 103. The number of slings 103 is set as required, and the number of slings 103 may be increased as appropriate as the length of the upper chord 51 increases, and it is preferable that the number of slings 103 is increased by an even number, for example, 4, 6, etc., in order to balance the center of gravity.
The lower ends of the two steel wire ropes 101 are connected with the carrying pole 9, and the upper ends of the two steel wire ropes 101 can be connected with the same hoisting ring so as to be connected with a crane conveniently. The upper ends of the slings 103 are connected with the carrying poles 9, and the lower ends of the slings 103 are connected with the upper chords.
As shown in fig. 2, two lifting eyes 10 are welded to the top surface of the carrying pole 9, at least two lifting eyes 10 are welded to the bottom surface of the carrying pole 9, and the number of lifting eyes 10 on the bottom surface of the carrying pole 9 is equal to the number of slings 103. The lifting lug 10 has a lifting hole 102. The steel wire rope 101 is connected with the lifting lug 10 on the top surface; the sling 103 is connected to the lifting eye 10 on the bottom surface.
Two reinforcing inclined struts 7 are added during hoisting. The stay 53 at the center of gravity of the beam string 5 is found. Two reinforcing diagonal braces 7 are respectively installed on both sides of the cable stay 53. Strengthen bracing 7 lower extreme and the lower extreme of that guy cable vaulting pole 53 of focus department and be connected, strengthen bracing 7 upper end and the upper end of the guy cable vaulting pole 53 of side and be connected, the node bolt anchor of connection.
