Problems solved by technology

Due to the need to adapt to the outer diameter of the largest roll, it is generally made larger, and the rolls below 2t are often unrolled when unfolding, which brings great difficulties to subsequent unfolding

Embodiment 1

[0032] Such as image 3 and Figure 4 The illustrated embodiment is a display stand, which includes coaxially arranged left and right restraints 1 and support rods 2. The restraint 1 includes an outer steel ring 3 and an inner steel ring 4 arranged on the same plane. The inner steel ring 4 is arranged in the outer steel ring 3, and is connected with the outer steel ring 3 by the connecting rod 5, preferably welding, the radius of the outer steel ring 3 is preferably 780mm, and the radius of the inner steel ring 4 is preferably 250mm; and the inner steel ring 4 and The outer steel ring 3 is not set with the same circle center, and the height of the center of the inner steel ring 4 to the ground is lower than that of the center of the outer steel ring 3, preferably lower than 96mm, so that the inner diameters of the various weight steel strand coils installed are equal to The inner steel rings 4 are all overlapped, so that the inner end of the steel strand coil can be spread ou...

Abstract

The invention discloses an exhibition shelf comprising a left restriction piece and a right restriction piece which are coaxial, and a support rod, wherein each restriction piece comprises an outer steel ring and an inner steel ring which are arranged in a same plane, the inner steel ring is arranged in the outer steel ring and is connected with the outer steel ring by connecting rods, spacing holes are formed in the radial direction of each connecting rod at intervals, the support rod penetrates through the spacing holes to connect the left restriction piece with the right restriction piece, and a support sleeve is sleeved outside the support rod. The exhibition shelf is simple in structure, convenient to use, low in cost and wide in application range.

Description

Technical field: [0001] The invention relates to a display frame and a method for displaying steel strands. Background technique: [0002] The prestressed steel strand is twisted by multi-strand steel wires with a wire diameter of 5-7mm. Its own rigidity and winding tension are very large. The factory state is a machine-rolled coil with an inner diameter of 80cm and a thickness of 75-76cm. The outer diameter is about 100-140cm according to the weight of each roll, the weight is 1-4.5t, the length is 900-4000m, and it is bound with 8 steel straps. Steel strands need to be removed before unwinding. Due to the rigidity of the steel strands and the tightness of the winding, once the constraint of the steel strands is lost, the diameter of the coil will expand rapidly, resulting in the phenomenon of staggered layers and disordered strands. It brings great difficulties for subsequent deployment, and even some line segments are scrapped due to bending deformation. [0003] The co...
