Description

Technical Field

[0001] This utility model relates to the field of drainage pipe fixing technology, and in particular to a combination tool for positioning and fixing drainage pipes of simply supported railway beams. Background Technology

[0002] Railway simply supported beams are generally prefabricated using general reference drawings. Drainage is achieved through pre-embedded drainage pipes on the beam surface, located at the arc of the beam. Traditional construction methods involve first installing a "well"-shaped steel bar at the top and bottom of the drainage pipe, welding these bars to the beam reinforcement for positioning and fixation. Next, cotton cloth or geotextile is used to fill the drainage pipe, preventing concrete from entering and solidifying the internal threads, which could affect the connection to the external drainage pipe. Finally, two right-angle wires are used to tie the drainage pipe opening to the beam reinforcement to prevent it from floating during concrete pouring. However, this traditional method is difficult to use, easily resulting in skewing, uneven longitudinal alignment, and poor, uneven, and unsightly interfaces between the pipe opening and the beam concrete. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a combination tool for positioning and fixing drainage pipes of simply supported railway beams.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A combination tool for positioning and fixing drainage pipes of simply supported railway beams includes a screw rod, a circular steel cover plate, and a nut welding platform. The nut welding platform is welded to the center of the drainage pipe on the template surface. A lower nut is welded to the middle of the nut welding platform. The circular steel cover plate is pressed onto the upper clamping position of the drainage pipe. The circular steel cover plate has a central opening. The screw rod passes through the central opening of the circular steel cover plate and is threadedly connected to the lower nut. An upper nut is threaded onto the upper surface of the circular steel cover plate on the screw rod. The circular steel cover plate is fixed by tightening the upper nut.

[0006] The screw is used in conjunction with the upper nut and the lower nut, and the thread diameter of the screw, the upper nut and the lower nut is not less than 10mm.

[0007] The drain pipe is filled with cotton cloth or geotextile on a circular steel cover plate until it is flush with the top opening of the drain pipe.

[0008] The top of the screw is welded with round steel.

[0009] The circular steel cover plate and the nut welding platform are both made of steel plates with a thickness of 3mm to 5mm.

[0010] The diameter of the circular steel cover plate is larger than the diameter of the screw.

[0011] The beneficial effects of this utility model are: the drainage pipe of this utility model is accurately positioned, vertical, and not skewed, with a smooth overall longitudinal line, which solves the problems of poor quality and unevenness of the concrete around the drainage pipe and the interface of the pipe opening, effectively avoids the problem of concrete entering the drainage pipe and solidifying the threads, and eliminates the problem of the drainage pipe floating.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] A combination tool for positioning and fixing drainage pipes of simply supported railway beams includes a screw rod 4, a circular steel cover plate 2, and a nut welding platform 5. The nut welding platform 5 is welded to the center of the drainage pipe 1 on the template surface. A lower nut 7 is welded to the middle of the nut welding platform 5. The circular steel cover plate 2 is pressed onto the upper clamping platform 11 of the drainage pipe 1. The circular steel cover plate 2 has a central opening. The screw rod 4 passes through the central opening of the circular steel cover plate 2 and is threadedly connected to the lower nut 7. An upper nut 3 is threadedly connected to the upper surface of the circular steel cover plate 2 on the screw rod 4. The circular steel cover plate 2 is fixed by tightening the upper nut 3.

[0020] The screw 4 is used in conjunction with the upper nut 3 and the lower nut 7, and the thread diameter of the screw 4, the upper nut 3 and the lower nut 7 is not less than 10mm.

[0021] The drain pipe 1 is filled with cotton cloth or geotextile on the circular steel cover plate 2 until it is flush with the top opening of the drain pipe 1.

[0022] The top of the screw 4 is welded with a round steel bar 6.

[0023] The circular steel cover plate 2 and the nut welding platform 5 are both made of steel plates with a thickness of 3mm to 5mm.

[0024] The diameter of the circular steel cover plate 2 is larger than the diameter of the screw 4.

[0025] During the operation, 1) first determine the center position of the drain pipe 1, then use a steel plate to weld the nut welding platform 5 at this position, and then weld the lower nut 7 on the nut welding platform 5;

[0026] 2) A hole is made in the center of the circular steel cover plate 2. The diameter of the hole is slightly larger than the diameter of the screw 4, but smaller than the size of the upper nut 3 and the lower nut 7.

[0027] 3) Press the circular steel cover plate 2 onto the drain pipe 1 clamp 11, and thread the screw 4 through the circular steel cover plate 2 and connect it with the lower nut 7.

[0028] 4) Tighten the nut 3 to fix the round steel cover plate 2. Fill the round steel cover plate 2 with cotton cloth or geotextile, etc., until it is flush with the opening of the drain pipe 1.
