[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] As Figure 1 、 2 、as shown in Figure 3, a fixing device for controlling the wall-out degree of a pre-embedded pipe includes a fixing unit and a tie rod 1. Two fixing units are symmetrically arranged, and the tie rod 1 is connected to the two fixing units. The fixing unit includes a mounting seat 2 and a fixing sleeve 3. The mounting seat 2 is arranged on the formwork and is located outside the formwork. The fixing sleeve 3 is fixedly connected to the mounting seat 2 and is located inside the mounting seat 2. The pre-embedded pipe is fixed between the two fixing sleeves 3.

[0025] As Figure 1 、 2 、as shown in Figure 3, the implementation principle of the present invention is to clamp and fix the wall-out part of the pre-embedded pipe through the fixing device and fix it on the formwork. Therefore, when pouring the wall, the pre-embedded pipe will be consistent with the formwork, avoiding the situation of inconsistent wall-out degrees. Specifically, the fixing unit is fixed on the formwork, the two fixing units are arranged oppositely, and then the two fixing units are tightened by the tie rod. The wall-out part of the pre-embedded pipe is clamped by the fixing sleeves 3 arranged oppositely on the two fixing units, so that the pre-embedded pipe maintains a stable state and is consistent with the formwork, and further makes the wall-out degree of the pre-embedded pipe meet the design requirements.

[0026] As Figure 2 、 4 、as shown in Figure 5, further, the mounting seat 2 is an L-shaped plate, including a mounting plate 21 and a fixing plate 22. The mounting plate 21 is vertically arranged outside the formwork and is closely attached to the outside of the formwork to prevent the pre-embedded pipe from tilting. The fixing plate 22 is vertically arranged on the mounting plate 21 and serves as the installation basis for the fixing sleeve 3. The fixing sleeve 3 is arranged inside the fixing plate 22.

[0027] As Figure 2, 4 As shown in Figure 5, further, the fixed sleeve 3 includes an arc-shaped pipe clamp 31 and a connecting rod 32. The opening of the arc-shaped pipe clamp 31 faces the inside of the fixing unit. The openings of the arc-shaped pipe clamps 31 on the two fixing units are arranged opposite to each other. The connecting rod 32 is arranged on the back of the arc-shaped pipe clamp 31 and is connected to the arc-shaped pipe clamp 31 and the fixing plate 22, thereby fixing the arc-shaped pipe clamp 31 on the fixing plate 22.

[0028] Further, mounting holes are provided on both the mounting plate 21 and the fixing plate 22. The end of the tie rod 1 is fixed in the mounting hole on the fixing plate 22 through a nut. A connecting bolt is provided in the mounting hole of the mounting plate 21. The fixing unit is fixedly connected to the formwork through the connecting bolt. Whether to fix the mounting seat 2 on the formwork is selected according to the construction requirements. When both ends of the embedded pipe protrude from the wall, the fixing is achieved by pulling against each other through the fixing devices arranged on both sides of the formwork, and there is no need to fix the mounting seat 2 on the formwork. When the embedded pipe protrudes from the wall on one side or the protruding positions do not correspond, it is necessary to fix the mounting seat 2 on the formwork to ensure the stability of the embedded pipe. When fixing the mounting seat 2 on the formwork, it can be fixed on the formwork or the backing strip through bolts.

[0029] Preferably, the length of the fixed sleeve 3 is the same as the width of the fixing plate 22.

[0030] Preferably, the central angle of the fixed sleeve 3 is less than 180°.

[0031] Preferably, the tie rod 1 is a screw rod, the mounting seat 2 is bent from a galvanized steel plate with a thickness of 10 mm, the arc-shaped pipe clamp 31 is a steel pipe clamp cut from a DN50 steel pipe, and the connecting rod 32 is a strip-shaped steel plate with a thickness of 10 mm.

[0032] Preferably, the arc-shaped pipe clamp 31 is welded to the mounting seat 2 through the connecting rod 32.

[0033] Preferably, the tie rods 1 are arranged in pairs. The two tie rods 1 tighten the two fixing units and are located on both sides of the fixed sleeve 3.

[0034] When the present utility model is in use, the fixing unit and the tie rod 1 are prefabricated according to the specification dimensions of the embedded pipe in the electrical design requirements. After prefabrication, they are transported to the construction site. During the binding process of the steel bar wall, the embedded pipe is placed in advance at the position marked on the drawing. During the formwork closing process, the fixing unit is clamped on the embedded pipe to control the wall exit degree and levelness of the embedded pipe. The mounting plate 21 of the fixing unit is closely attached to the outside of the formwork to prevent the embedded pipe from tilting. Then, the tie rod 1 is installed and tightened. After tightening, the wall is poured. When the formwork of the wall is removed, the fixing device is removed.
