The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a low-deformation protective railing, such as Figures 1-5 As shown, the low-deformation protective railing includes:

[0024] The main support frame 100 includes a trapezoidal outer frame 110 and a first connecting rod 120 and a second connecting rod 130 connected within the outer frame 110. The long side of the outer frame 110 is a first connecting surface 1001, and the short side of the outer frame 110 is a second connecting surface 1002.

[0025] The linkage assembly 300 comprises several sets of main support frames 100 arranged in a row. The first connecting surfaces 1001 on adjacent main support frames 100 face different directions. Specifically, the main support frames 100 with trapezoidal structures are arranged in opposite directions. Adjacent main support frames 100 are connected by the linkage assembly 300. The linkage assembly 300 includes a first diagonal tie rod 310, a second diagonal tie rod 320, a third diagonal tie rod 330, and a fourth diagonal tie rod 340. Adjacent sets of main support frames 100 are connected by the first diagonal tie rod 310, the second diagonal tie rod 320, the third diagonal tie rod 330, and the fourth diagonal tie rod 340.

[0026] In this embodiment, the adjacent main support frames 100 adopt a cross structure. The side walls of the array structure formed by the main support frames 100 are provided with side guard plates 200. The side guard plates 200 are existing technology. The trapezoidal main support frames 100 are staggered to achieve the same supporting effect on both sides. Combined with the connection effect of the connecting rod combination 300 between adjacent main support frames 100, the function of the connecting rod combination 300 is to help the adjacent main support frames 100 become a whole structure. For the low deformation protective railing with staggered arrangement, it can provide support on both sides and meet the protection requirements.

[0027] Here, there are two sets of side guard plates 200 on each side. One set of side guard plates 200 closer to the ground is connected to all the main support frames 100, while the side guard plates 200 farther from the ground are only connected to part of the main support frames 100 due to the staggered arrangement. If necessary, only one set of side guard plates 200 closer to the ground can be arranged.

[0028] In a preferred embodiment of this invention, the outer frame 110 is provided with a first connection point 101, a second connection point 102, a third connection point 103 and a fourth connection point 104 on both sides for fixing the connecting rod assembly 300.

[0029] In this embodiment, the first diagonal tie rod 310 is connected to the first connection point 101 of one set of main support frames 100 and the second connection point 102 of another set of main support frames 100; the second diagonal tie rod 320 is connected to the second connection point 102 of one set of main support frames 100 and the first connection point 101 of another set of main support frames 100; the third diagonal tie rod 330 is connected to the third connection point 103 of one set of main support frames 100 and the third connection point 103 of another set of main support frames 100; and the fourth diagonal tie rod 340 is connected to the fourth connection point 104 of one set of main support frames 100 and the fourth connection point 104 of another set of main support frames 100.

[0030] Here, the first diagonal tie rod 310 and the second diagonal tie rod 320 are designed to cross each other, which improves the connection effect of the two main load-bearing frames 100. It is necessary to pay attention to the staggered arrangement of the first connection point 101 and the second connection point 102 to avoid interference caused by the cross design.

[0031] In a preferred embodiment of this invention, the main support frame 100 is connected to the pre-set concrete base of the median strip using a bolt structure, and the connection method between the side guard plate 200 and the first connecting surface 1001 and the second connecting surface 1002 is the same as that in the prior art.

[0032] In this embodiment, the first diagonal brace 310, the second diagonal brace 320, the third diagonal brace 330, and the fourth diagonal brace 340 have the same structure and are mainly connected using existing diagonal bracing structures. Here, the first connection point 101, the second connection point 102, the third connection point 103, and the fourth connection point 104 are provided with connection structures for the first diagonal brace 310, the second diagonal brace 320, the third diagonal brace 330, and the fourth diagonal brace 340.

[0033] The first diagonal tie rod 310, the second diagonal tie rod 320, the third diagonal tie rod 330 and the fourth diagonal tie rod 340 can also be connected to the main support frame 100 by on-site welding.
