[0002] With the rapid development of the construction industry, the uses, structural types, and functions of various types of buildings are constantly developing and changing. The construction quality of buildings is becoming more standardized and strict, and the quality of professional construction will directly affect the overall quality goals. During the construction stage of the main structure of the building project, the horizontal opening reservation and embedding of shear walls, frame beams and other components have become a major process for professional construction quality control. At present, the reservation and embedding of horizontal openings in the main construction stage adopts welding additional steel bars around the rigid sleeve, and then the additional steel bars are welded and fixed to the shear wall and frame beam steel bars according to the position of the reserved opening, and finally the shear wall and frame beam templates are supported and concrete is poured. In this construction method, the rigid sleeve is fixed to the shear wall and frame beam steel bars by welding additional steel bars, and the binding and fixing construction requirements of the shear wall and frame beam steel bars are relatively high. When pouring concrete, it is very easy to cause the rigid sleeve to move due to loose binding and fixation under the impact load of concrete dumping and vibration load of the vibrating rod, resulting in drilling holes in the wall during pipeline installation, affecting the use function and damaging the structure, leaving quality risks.

[0004] The horizontal reserved sleeve precise positioning device described in the utility model comprises a C-shaped base support at the bottom and a C-shaped clamping ring at the top. The C-shaped base support and the C-shaped clamping ring can be fixed together to form a complete circular ring, and the inner diameter of the circular ring is adapted to the outer diameter of the reserved sleeve; the C-shaped base support and the C-shaped clamping ring can be fixed on the template.

[0005] Wherein, the outer peripheral surfaces of the C-shaped base and the C-shaped clamping ring are both provided with raised fixing blocks, and nail holes are opened on the fixing blocks.

[0006] Preferably, there are multiple fixing blocks, which are evenly distributed on the outer circumference of the C-shaped base and the C-shaped clamping ring.

[0007] Both ends of the C-shaped base and the C-shaped clamping ring of the utility model are provided with butt joint plates, threaded holes are opened on the butt joint plates, and the C-shaped base and the C-shaped clamping ring can be fixed together by bolts.

[0008] In addition, a rubber ring is provided between the inner diameter of the ring and the outer diameter of the reserved casing to increase the sealing and tightness of the connection.

[0009] The utility model fixes the C-shaped base and the C-shaped clamp ring on the reserved sleeve installation position of the template on both sides of the shear wall or frame beam, places the reserved sleeve in the C-shaped base, and then uses the C-shaped clamp ring to close and fix. The C-shaped base and the C-shaped clamp ring are fixedly installed on the template, and the reserved sleeve is reliably connected to the circular shape formed by the C-shaped base and the C-shaped clamp ring, completing the entire positioning and fixing installation structure.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The horizontal reserved sleeve precise positioning device described in the utility model can accurately locate the reserved hole installation position on the template surface, and then fix the C-type base and C-type clamping ring on the template according to the positioning. The reserved sleeve and the circular shape formed by the C-type base and C-type clamping ring are reliably connected, with high stability, and can effectively prevent the displacement of the reserved sleeve, ensuring the construction quality of the horizontal reserved hole. The device has a simple structure and is easy to manufacture, with low manufacturing and use costs, and has a relatively superior performance-price ratio. It meets the requirements of green environmental protection in the current construction field and has good social and economic value. BRIEF DESCRIPTION OF THE DRAWINGS
