Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and relates to the construction of culverts for roadbed drainage, specifically to a culvert steel cage processing device. Background Technology

[0002] During road construction, to prevent water erosion of the roadbed, culverts are often installed beneath the roadbed to drain surface runoff. These culverts are precast reinforced concrete; the reinforcing cage is fabricated first, and then concrete is poured. Because culvert segments are relatively short, and the number of culverts designed for a project is generally small, using automatic welding machines to fabricate the reinforcing cages is costly. Therefore, manual fabrication is often used during construction. First, 2-3 hoops are bent, then the main reinforcing bars are assembled with the hoops using spot welding or binding to form the reinforcing cage frame, and finally, the hoops are wrapped around it. Manual fabrication is not only inefficient, but the reinforcing cage is also prone to deformation during the hoop wrapping process. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a simple culvert reinforcement cage processing device to improve construction efficiency, save costs, and reduce the labor intensity of construction workers.

[0004] The technical solution of this utility model is as follows:

[0005] A culvert reinforcement cage processing device is characterized in that it includes a base, a turntable, and a reinforcement cage. The base has a vertical rotating shaft at its center, the turntable is supported on the top surface of the base, and the turntable has a shaft hole at its center. The turntable is fitted onto the rotating shaft through the shaft hole and can rotate around the rotating shaft. The reinforcement cage includes multiple vertically spaced circumferentially arranged steel bars. At least two annular hoops are welded to the vertical steel bars, and the lower end of each vertical steel bar is welded to the top surface of the turntable.

[0006] This utility model has a simple structure and can be welded using steel bars and steel plate bars available on the construction site. The material cost is low, and it is cheaper and more economical than automatic rolling welding machines. The steel cage is wound with hoops by manually pushing the turntable, which can greatly reduce the labor intensity of workers and improve construction efficiency. One set of equipment can be equipped with 3-4 workers to achieve the efficiency of producing one set of steel cages per hour, while ensuring the quality of the steel cages. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0008] Figure 2 This is a structural diagram of the base. Detailed Implementation

[0009] like Figure 1 , Figure 2As shown, this utility model includes a base 1, a turntable 2, and a steel reinforcement frame 3. The base 1 has a vertical rotating shaft 11 at its center. The turntable is supported on the top surface of the base. The turntable 2 has a shaft hole at its center. It is fitted onto the rotating shaft through the shaft hole and can rotate around the rotating shaft. The steel reinforcement frame 3 includes multiple vertical steel bars 31 arranged circumferentially at equal intervals. At least two annular hoops 32 are welded to the vertical steel bars. The lower end of each vertical steel bar 31 is welded to the top surface of the turntable.

[0010] like Figure 2 As shown in the figure, in a specific embodiment of the present invention, the base 1 includes four lower horizontal ribs 12 and four upper horizontal ribs 13. The four lower horizontal ribs 12 are welded in a cross shape to the lower end of the rotating shaft 11. Connecting ribs 14 are welded between adjacent ends of the four lower horizontal ribs. The four upper horizontal ribs 13 are welded in a cross shape to a certain height on the rotating shaft 11. A pulley 15 is fitted on each of the four upper horizontal ribs 13 near its end. A vertical supporting rib 16 is welded between the upper and lower horizontal ribs at a certain distance on both sides of each pulley 15. The turntable 2 is supported on the four pulleys 15 of the base.

[0011] The vertical support rib 16 provides support to the upper horizontal rib 13 on the one hand, and limits the pulley 15 on the other hand; when the turntable 2 rotates on the base, the pulley 15 rolls at the bottom of the turntable, making it easier for the turntable to rotate on the base.

[0012] In a specific implementation of this utility model, in order to increase the strength of the steel reinforcement cage 3, a triangular reinforcing rib 33 is welded inside each annular hoop of the steel reinforcement cage.

[0013] In a specific implementation of this utility model, a sleeve 4 can be fitted onto the top of the turntable on the rotating shaft. The function of the sleeve 4 is to facilitate the measurement of the radius of the reinforcing steel cage during construction and to monitor the deformation of the reinforcing steel cage, so as to ensure that the dimensions of the culvert reinforcing steel cage meet the design specifications.

[0014] The method of using this utility model is as follows:

[0015] First, the vertical main bars of the culvert reinforcement cage are temporarily tied to the reinforcement skeleton at predetermined intervals using tie wire. Then, by manually rotating a turntable, the stirrups of the reinforcement cage are spirally wound from the bottom up, while the vertical main bars and circumferential stirrups are tied simultaneously to form the reinforcement cage. After the reinforcement cage is formed, the temporary ties between the main bars and the reinforcement skeleton are released, and the reinforcement cage is removed from the reinforcement skeleton and transferred to the storage area, where subsequent reinforcement cage fabrication is carried out.
