[0006] Supporting part;

[0007] a lifting portion, the lifting portion being arranged on the supporting portion, the lifting portion being used to facilitate lifting the entire device, and

[0008] The clamping part is arranged on the supporting part, and the supporting part is used to effectively shield the arch foot connecting plate, and the clamping part is used to clamp with the I-beam of the tunnel support.

[0009] Preferably, the support portion comprises a steel plate, and the steel plate is arranged horizontally.

[0010] Preferably, the lifting portion includes a handle, and the handle is U-shaped, with the U-shaped opening of the handle facing downward and fixedly connected to the top of the steel plate.

[0011] Preferably, the handle is welded to the top of the steel plate, and the handle is located in the center of the steel plate.

[0012] Preferably, the engaging portion comprises a strip groove, and the strip groove is symmetrically opened at the edge of the steel plate.

[0013] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0014] The steel frame arch foot connecting plate baffle device is provided with a lifting part on the supporting part, and two clamping parts are provided on the supporting part. The lifting part is used to lift the whole device, the supporting part is used to effectively shield, and the clamping part is used to clamp with the I-beam of the tunnel support. The device is installed on the upper side of the arch foot connecting plate, which can effectively shield and prevent the invasion of external debris, and protect the connecting plate from being wrapped by shotcrete and affecting the next process. At the same time, it can also improve the overall stability of the connection area to a certain extent. The device has a simple structure, low cost, and convenient construction. At the same time, the processing flow is simple and the operation is convenient. Moreover, the baffle can be pulled out when the connecting plate is bolted during construction, so that the device can be recycled, which solves the problem that slag or other debris may accumulate in the arch foot connection area in the prior art, and these debris may cause unnecessary manpower and material resources in the next process, and threaten the stability of the connection part, thereby affecting the structural safety.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3As shown, a steel frame arch foot connecting plate baffle device comprises a supporting part 1, a lifting part 2 and a clamping part 3, wherein the lifting part 2 is arranged on the supporting part 1, and the clamping part 3 is arranged on the supporting part 1. The function of the lifting part 2 is to facilitate lifting the entire device, the function of the supporting part 1 is to effectively shield the arch foot connecting plate, and the function of the clamping part 3 is to clamp with the I-beam of the tunnel support. The device is installed on the upper side of the arch foot connecting plate, which can effectively shield and prevent the invasion of external debris, and protect the connecting plate from being wrapped by sprayed concrete to affect the next process, and can also improve the overall stability of the connecting area to a certain extent. The device has a simple structure, low cost, and convenient construction. At the same time, the processing flow is simple and the operation is convenient. Moreover, the baffle can be pulled out when the connecting plate is bolted during construction, so that the device can be recycled.

[0021] like Figure 1-Figure 3 As shown, the support portion 1 includes a steel plate 11, which is rectangular and horizontally arranged. The lifting portion 2 includes a handle 21, which is U-shaped. The U-shaped opening of the handle 21 is downward and fixedly connected to the top of the steel plate 11. The handle 21 is welded to the top of the steel plate 11. The handle 21 is convenient for workers to lift the device to the construction site. The handle 21 is located at the center of the steel plate 11. The clamping portion 3 includes a strip groove 31, which is symmetrically opened at the edge of the steel plate 11. Four strip grooves 31 are arranged on one steel plate 11.
