Embodiment Construction
[0033] The content of the present invention will be further described below in conjunction with the accompanying drawings.
[0034] Such as figure 1 As shown, the self-climbing construction device of the present invention is used to lift radial cables in the construction of large-scale flexible cable-net structures. In the construction of large-scale flexible cable-net structures, steel structure lugs 5 are provided, which include Rotatable fork ears 1, steel strands 2, load-bearing frames 3 and at least two self-climbing jacks 4, the rotatable fork ears 1 are U-shaped structures, and the rotatable fork ears 1 are hinged on the steel structure ear plates 5, the self-climbing jack 4 is fixedly connected to the load-bearing frame 3, and the steel strand 2 passes through the self-climbing jack 4 and the load-bearing frame 5 and is fixed at the lower end of the rotatable fork ear 1. exist figure 1 Among them, the cable 6 is installed in the middle part of the bearing frame 3, an...

The invention relates to the constructional engineering field and in particular relates to a self-climbing jack and a self-climbing construction device comprising the self-climbing jack, and also provides a self-climbing construction method by using the self-climbing construction device. The self-climbing jack is composed of a straight-through jack, an after propeller, a front locker and a front anchor hauling-off device, wherein the front anchor hauling-off device comprises a front anchor hauling-off device cover plate and a front anchor hauling-off device adjusting core. The self-climbing jack, the self-climbing construction device and the self-climbing construction method have the advantages that the self-climbing jack is improved to be adaptive to clamping steel strands of various specifications, the operation is simpler and each steel strand is evener in stress during working, and simultaneously, the cost can be greatly reduced, and the advantages of low weight, simple structure, convenient construction operation, convenience for mounting and demounting and the like are achieved, and moreover, stress on the straight-through jack and the steel strands can be automatically unloaded and the safety of construction is greatly improved.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a self-climbing construction method using the self-climbing construction device. Background technique [0002] In the construction of large-scale flexible cable net structures, the method of lifting radial cables is usually used. There are generally two methods of lifting: one is to place the lifting jack on the surrounding ring beam for lifting; the other is to place the lifting jack at the head of the hoisted cable to climb. In actual construction, the latter lifting method is widely used. However, when the latter lifting method climbs, the force direction of the cable is not vertical but inclined. For an ordinary 100T lifting roof, the height is about 1.2m and the weight is about 800kg. Due to its large weight and volume, it is easy to As a result, the force direction of the jack and the axial direction of the hoisted cable are not in a straight line. The ordinary lif...
