Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction tools, and in particular to a simple triangular anti-rollover steel strand support. Background Technology
[0002] Steel strands used in construction are typically high-strength steel wire ropes for reinforcing and prestressing concrete structures. By applying pretension, they enhance the load-bearing capacity and durability of concrete structures, and are widely used, particularly in the reinforcement of major structural elements such as beams, columns, and slabs. Steel strand supports are devices used to place and support steel strands (ropes). These supports help manage the placement of the steel strands, keeping them neat and preventing tangling, playing a crucial role in improving laying efficiency and ensuring construction safety.
[0003] Currently, steel strands are typically laid out within square cage supports. In the early stages of laying, the weight of the steel strand exerts pressure on the cage support, maintaining stability. However, as the weight decreases in the later stages, the stability of the square cage deteriorates, making it prone to tipping over under the tension of the laid strand. Furthermore, the current cage supports cannot be adjusted to suit the specific size of the steel strand coil, resulting in generally large cage sizes. Later, auxiliary tools such as shims or blocks are used for fixation as needed, which is cumbersome and provides poor positioning results, and therefore requires improvement. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a simple triangular anti-rollover steel strand support.
[0005] The technical solution of this utility model is: a simple triangular anti-rollover steel strand bracket, comprising two triangular frames, each a right triangle, arranged side by side with a gap between them, the gap being adjustable as needed. Each triangular frame consists of a base rod and two side rods connected to each other at both ends of the base rod. An upper pressure rod is connected between the upper parts of the corresponding side rods in the two triangular frames, the two upper pressure rods being of the same height. Two lower support rods are connected side by side between the corresponding base rods, the two lower support rods being connected to the base rod in a centrally symmetrical manner. An end-face limiting rod is connected between the middle of the base rod and the middle of the side rods in the triangular frames, and an end-face limiting rod is connected between the middle of the side rods.
[0006] Preferably, two vertical legs are symmetrically welded and fixed to the middle of the bottom rod in the triangular frame, and a base plate can be fixedly connected between the two vertical legs to increase the contact area between the vertical legs and the ground.
[0007] Preferably, the end face limiting rods are welded and fixed to the triangular frame, and the outer ends of the three end face limiting rods correspond to each other to form an equilateral triangle.
[0008] Preferably, the end face limiting rods between the bottom rod and the two side rods are connected to a line-laying support rod via a cross-shaped fastener A, and the line-laying support rod is in a horizontal state after being connected.
[0009] Preferably, the cross-shaped fastener A is a rotary cross-shaped fastener, used to adapt to the height adjustment of the line-laying support rod.
[0010] Preferably, both ends of the upper pressure rod are fixedly connected to the two side rods by cross fasteners B, and the length of the upper pressure rod is greater than the distance between the two triangular frames.
[0011] Preferably, both ends of the lower support rod are fixedly connected to the bottom rod by cross fastener C, the length of the lower support rod is greater than the distance between the two triangular frames, and the length of the lower support rod is the same as the length of the upper pressure rod.
[0012] Preferably, the ends of the side rods and the bottom rod in the triangular frame are fixedly connected by welding to ensure that the triangular frame has sufficient connection strength and stability.
[0013] Preferably, the side rod, bottom rod, upper pressure rod, and lower support rod are all steel pipes.
[0014] The beneficial technical effects of this utility model are:
[0015] (1) The steel strand bracket adjusts the distance between the upper pressure rod and the lower support rod by using cross fasteners, thereby changing the size of the space inside the bracket for clamping and fixing the steel strand, so as to match different models and sizes of steel strand rolls. The overall applicability and flexibility are relatively high, and it has the advantages of simple and efficient adjustment.
[0016] (2) After the triangular frame of the steel strand support is connected by the pressure rod and the support rod, it forms a rollover-resistant support structure that is wider at the bottom and narrower at the top. This helps to improve the overall stability of the support after the weight of the steel strand is reduced in the later stage of unwinding, and it is not easy for the strand to roll over or tip over. The overall stability is good. Attached Figure Description

[0022] Example 1, see appendix to the instruction manual. Figure 1-4 A simple triangular anti-rollover steel strand support includes two triangular frames 01, which are arranged side by side with a gap between them. The space formed by the gap is used to load the steel strand roll 41. Each triangular frame 01 consists of a base rod 11 and two side rods 12 connected to each other between the two ends of the base rod. An upper pressure rod 21 is connected between the upper parts of the corresponding side rods 12 in the two triangular frames. Two lower support rods 22 are connected side by side between the corresponding base rods 11. The two lower support rods are used to support the lower arc surface of the roll, and the two upper pressure rods 21 are used to press the roll onto the upper arc surface.
[0023] An end-face limiting rod 14 is connected between the middle of the bottom rod 11 and the two side rods 12 in the triangular frame. The end-face limiting rod 14 is also connected between the middle of the two side rods. The end-face limiting rod is welded and fixed to the triangular frame 01. The outer ends of the three end-face limiting rods 14 correspond to each other to form a triangle. The end-face limiting rods forming the triangular structure are used to cover and support the end face of the coil. Combined with the upper pressure rod 21 and the lower support rod 22, the steel strand coil 41 is clamped and fixed in the bracket as a whole to prevent the coil from spreading outward due to stress after the packaging is removed.
[0024] Two vertical support legs 13 are symmetrically welded and fixed in the middle of the bottom rod 11 in the triangular frame. The vertical support legs 13 are used to slightly raise the bracket to a certain height so that the two lower support rods 22 can support the steel strand coil 41 and prevent it from contacting the ground.
[0025] The ends of the side rod 12 and the bottom rod 11 in the triangular frame 01 are fixedly connected by welding to ensure the structural strength of the triangular frame 01. Furthermore, the side rod 12, bottom rod 11, upper pressure rod 21 and lower support rod 22 of the steel strand bracket are all steel pipes, and the cross fastener is also a common building component on the construction site. Therefore, the steel strand bracket can be quickly processed using common components on the construction site, which helps to save material costs.
[0026] When using this steel strand support, the two upper pressure rods 21 are removed, the steel strand roll 41 is hoisted between the two triangular frames 01 and placed on the two lower support rods 22. Then, the two upper pressure rods 21 are reinstalled, and the roll is fixed tightly between the two triangular frames 01, the two lower support rods 22 and the two upper pressure rods 21. The free end of the steel strand is pulled out from the center for unwinding. The triangularly arranged end limit rods 14 provide protective limit for the steel strand, preventing it from swinging too much due to stress. This steel strand support forms a roll-over prevention support structure that is wider at the bottom and narrower at the top. Even after the weight of the steel strand decreases in the later stages of unwinding, the support still has high stability and is not prone to rollover or tipping.
[0027] Example 2, see appendix to the instruction manual. Figure 1-4 Based on Embodiment 1, this embodiment adds a wire-laying support rod 311 connected to the end face limiting rods 14 between the bottom rod 11 and the two side rods 12 via a cross-shaped fastener A 31. The cross-shaped fastener A 31 is a rotating cross-shaped fastener. The wire-laying support rod 311 is used to support the steel strand during wire laying, preventing the steel strand from swinging significantly due to its own stress. The height of the wire-laying support rod can be adjusted between the two inclined side rods 12 via the rotating cross-shaped fastener, so that it matches the thickness of the coil after unwinding, thereby improving the support efficiency.
[0028] Furthermore, both ends of the upper pressure rod 21 are fixedly connected to the two side rods 12 via cross fastener B 32, and both ends of the lower support rod 22 are fixedly connected to the bottom rod 11 via cross fastener C 33. Therefore, the distance between the upper pressure rod 21 and the lower support rod 22 can be quickly adjusted by tightening or loosening the cross fasteners, thereby changing the size of the clamping and fixing space for the steel strand coil 41 inside the bracket. This allows the bracket to be matched with steel strand coils of different sizes and models, resulting in high overall applicability and flexibility.
