[0022] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0023] like Figure 1 As shown, an embodiment of the present application provides a steel support locking foot anchor pipe reinforcement device, which includes a positioning plate 1, a steel support 3 and a locking foot anchor pipe 4, the positioning plate 1 includes at least one positioning hole 2, and the positioning hole 2 penetrates the positioning plate 1 along the thickness direction of the positioning plate 1; the steel support 3 is located on one side of the positioning plate 1 along the thickness direction, and the steel support 3 is fixedly connected to the positioning plate 1; there is a connection state between the locking foot anchor pipe 4 and the positioning plate 1, and in the connection state, the locking foot anchor pipe 4 passes through the positioning hole 2, and the locking foot anchor pipe 4 is fixedly connected to the positioning plate 1 by welding.

[0024] The steel support locking foot anchor pipe reinforcement device in the embodiment of the present application firmly connects the steel support 3 and the locking foot anchor pipe 4 through the positioning plate 1, so as to give full play to the role of the locking foot anchor pipe 4 and improve the overall support effect of the initial support. Different positioning plates 1 and positioning holes 2 sizes can adapt to different types of diameters of locking foot anchor pipes 4. In addition, by presetting different positions of the positioning plate 1 on the steel support 3, it can also adapt to the design requirements of different positions of the locking foot anchor pipe 4. The steel support locking foot anchor pipe reinforcement device has strong adaptability and has the advantages of easy installation, simple operation, good reinforcement effect, and low cost.

[0025] like Figure 1As shown, in a specific embodiment, the number of the positioning plates 1 is at least two, and the at least two positioning plates 1 are arranged at intervals along the length direction of the steel support 3, and the positioning plates 1 and the steel support 3 are fixedly connected by welding. In addition, the number of the positioning holes 2 is also at least two, and the at least two positioning holes 2 are respectively arranged on the positioning plates 1 on both sides of the steel support 3 in the width direction.

[0026] Specifically, during the manufacturing and processing of the steel support 3, according to the requirements of the design blueprint, the processed positioning plate 1 is welded to the steel support 3 in advance at the position shown in the blueprint. During the on-site construction, after the steel support 3 is installed as per the design requirements, a drilling rig is used to control the angle and drill a positioning hole 2 at a preset position. After the drilling is completed, the locking foot anchor pipe 4 is installed in place, and the locking foot anchor pipe 4 is firmly welded to the positioning plate 1, and the locking foot anchor pipe 4 is grouted as required to increase the rigidity of the locking foot anchor pipe 4.

[0027] The position of the positioning hole 2 on the positioning plate 1 can be adjusted according to the diameter of the locking foot anchor pipe 4. When the diameter of the locking foot anchor pipe 4 is larger than the size of the positioning plate 1, the size of the large positioning plate 1 and the diameter of the opening can be increased. Through adjustment, the steel support locking foot anchor pipe reinforcement device can adapt to locking foot anchor pipes 4 of various diameters. In addition, during the manufacturing process of the steel support 3, the position of the positioning plate 1 on the steel support 3 can be adjusted according to the design requirements, so as to better adapt to various positions of the locking foot anchor pipe 4.

[0028] like Figure 1 As shown, in a specific embodiment, the positioning plate 1 is a steel plate with a thickness of not less than 8 mm, and the size of the positioning plate 1 is not less than 500 mm x 150 mm. Generally speaking, the positioning plate 1 with a thickness of 8 mm and a size of 500 mm x 150 mm can meet most of the current Zhihu needs. In addition, the opening size of the positioning hole 2 is determined according to the size of the locking foot anchor tube 4. Conventionally, the positioning hole 2 has a first aperture, a second aperture and a third aperture. The size of the first aperture is ф60 mm, the size of the second aperture is ф90 mm, and the size of the third aperture is ф130 mm; the first aperture is used to match the locking foot anchor tube 4 with a connection size of ф42 mm, the second aperture is used to match the locking foot anchor tube 4 with a connection size of ф76 mm, and the third aperture is used to match the locking foot anchor tube 4 with a connection size of ф108 mm.

[0029] The installation and precautions of the steel support locking foot anchor pipe reinforcement device in the embodiment of the present application are as follows:

[0030] During the on-site construction process, after the steel support 3 is installed according to the design requirements, a drilling rig is used to control the angle and drill the positioning hole 2 from the preset position. After the drilling is completed, the locking foot anchor pipe 4 is installed in place, and the locking foot anchor pipe 4 is firmly welded to the positioning plate 1, and the anchor pipe is grouted as required to improve the rigidity of the locking foot anchor pipe 4.

[0031] To ensure the effectiveness of the device, the following matters should be noted during use: 1. The welding quality between the positioning plate 1 and the steel support 3, and the welding quality between the locking foot anchor pipe 4 and the positioning plate 1 must be well controlled; 2. During the drilling process of the locking foot anchor pipe 4, care should be taken to avoid disturbing the steel support 3, and attention should be paid to controlling the drilling position and the angle of the locking foot anchor pipe 4.

[0032] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
