[0002] The inner side of the process trench is covered with stainless steel, and the outer side is L50×5 angle steel made of Q235B. Its main function is to isolate radioactive materials and prevent them from leaking, so as to block radioactive materials from entering non-radioactive areas or environments. At the same time, it is also a structural channel for the pipeline where the high-radioactive media of each sub-item main process system is located outdoors.

In addition, the method of welding internal supports on the steel covering not only destroyed the original protective film of the steel covering, but also increased the input of personnel and materials, greatly increased the construction cost, and failed to meet the precision requirements of trench installation.

[0022] <Example>

[0023] like Figure 1 As shown, in this embodiment, the steel cladding member internal support device 10 is used to internally support the steel cladding member 20; the steel cladding member 20 is a process pipe trench, having a frame 21 in a "U" shape as a whole and two steel claddings 22 respectively arranged on the inner surfaces of two side portions of the frame 21. The steel cladding member internal support device 10 includes a first horizontal support rod portion, a second horizontal support rod portion, a vertical support rod portion and a suction cup portion.

[0024] like Figure 1 As shown, the first horizontal support rod portion is used to abut the inner surfaces of the two steel claddings 22 of the steel cladding member 20 toward the outside, and includes M pairs of first horizontal support rods 11 arranged at intervals in the height direction of the steel cladding member 20. M is a positive integer not less than 2. In this embodiment, M is 4 for illustration.

[0025] Each pair of first horizontal support rods 11 extends along the length direction of the steel cladding member 20, and respectively abuts against the inner surfaces of the two steel claddings 22. The design of the first horizontal support rods 11 abutting against the inner surfaces of the steel claddings 22 can protect the original protective film on the inner surface of the steel claddings and avoid the quality risk of the steel cladding member caused by welding.

[0026] In this embodiment, a stainless steel plate (not shown in the figure) is provided between the first horizontal support rod 11 and the corresponding steel covering 22, which increases the area where the first horizontal support rod 11 and the steel covering 22 are attached and abutted, and can better meet the protection requirements of the original protective film on the inner surface of the steel covering.

[0029] The two ends of each second horizontal support rod 12 are detachably connected to a corresponding pair of first horizontal support rods 11 through a spacing adjustment mechanism, so that the distance between the pair of first horizontal support rods 11 matches the distance between the two steel claddings 22 to be supported, thereby meeting the requirements of steel cladding components 20 of different sizes.

[0030] In this embodiment, the above-mentioned spacing adjustment mechanism is a screw nut structure, including a screw 12a and two nuts (not shown in the figure). The screw 12a is arranged along the width direction of the steel cladding member 20, and the outer surfaces of its two ends are provided with external threads with opposite spiral directions. The two nuts are respectively fixedly connected to the second horizontal support rod 12 and the first horizontal support rod 11, and are respectively sleeved on the two ends of the screw 12a. When the screw 12a rotates in a certain direction, the two nuts can approach or move away from each other, thereby adjusting the distance between the corresponding pair of first horizontal support rods 11, so that the two first horizontal support rods 11 are respectively in contact with the inner surfaces of the two steel claddings 22.

[0031] like Figure 1 As shown, the vertical support rod and the second horizontal support rod together constitute a three-dimensional support structure to support and install the first horizontal support rod. The vertical support rod comprises N vertical support rod units corresponding to the N second horizontal support rod units, and each vertical support rod unit comprises L vertical support rods 13 arranged at intervals in the width direction of the steel cladding member 20; L is a positive integer not less than 2, and in this embodiment, L is 2 for illustration.

[0032] Each vertical support rod 13 is detachably connected to the corresponding M second horizontal support rods 12 , and the bottom end of the vertical support rod 13 is detachably connected to the bottom of the skeleton 21 .

[0033] In this embodiment, if Figure 2 As shown, the vertical support rod 13 is detachably connected to the corresponding second horizontal support rod 12 via a bolt member 13a; both the vertical support rod 13 and the second horizontal support rod 12 are provided with a bolt mounting hole (not shown in the figure) for the bolt member 13a to pass through.

[0034] In this embodiment, if Figure 3 As shown, the bottom of the skeleton 21 has an angle steel 21a corresponding to the vertical support rod 13, and a bolt member 13b is passed between the angle steel 21a and the corresponding vertical support rod 13; both the angle steel 21a and the vertical support rod 13 are provided with bolt mounting holes (not shown in the figure) for the bolt member 13b to pass through.

[0035] like Figure 1 As shown, the suction cup portion includes one suction cup unit, or a plurality of suction cup units spaced apart in the height direction of the steel cladding member 20; in this embodiment, the suction cup portion including one suction cup unit is taken as an example for description.

[0036] The suction cup unit is located between two adjacent pairs of first horizontal support rods 11, and contains a plurality of suction cup assemblies arranged at intervals in the length direction of the steel cladding member 20; each suction cup assembly has a pair of suction cups 14 respectively engaged with the inner surfaces of the two steel claddings 22, and a third horizontal support rod 15 whose two ends are respectively detachably connected to the pair of suction cups 14.

[0037] In this embodiment, the suction cup 14 is a strong suction cup with a relatively large suction force.

[0038] In this embodiment, the third horizontal support rod 15 and the corresponding suction cup 14 are also detachably connected through the above-mentioned spacing adjustment mechanism, wherein two nuts are respectively fixedly connected to the third horizontal support rod 15 and the suction cup 14, and are respectively sleeved on the two ends of the screw rod. When the screw rod rotates, the two nuts can move closer to or farther from each other, thereby adjusting the distance between the corresponding pair of suction cups 14, so that the two suction cups 14 are respectively attracted to the inner surfaces of the two steel coverings 22.

[0039] In this embodiment, the first horizontal support rod 11, the second horizontal support rod 12, the third horizontal support rod 15 and the vertical support rod 13 are all made of channel steel made of Q235B.
