Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar bending, and in particular relates to a bending angle control tool for steel bars at the head of a bridge pile foundation. Background Art

[0002] Pile head reinforcement, also known as welded reinforcement, is a type of steel bar used in pile foundation construction. Pile head reinforcement is widely used in various pile foundation construction sites, such as highways and water conservancy projects.

[0003] Bored cast-in-place piles are an important part of bridge construction. Bored cast-in-place piles are piles made by forming pile holes in the foundation soil at the construction site through mechanical drilling, steel pipe squeezing, or manual excavation, and then placing a steel cage inside and pouring concrete. During the construction of bored cast-in-place piles, bending the pile head steel bars is one of the important processes. The common bending of the pile head steel bars of bored cast-in-place piles is performed on-site using the traditional "hanging line method". After bending, it is easy for the bending angle and opening size of the pile head steel bars to not meet the design requirements. When a large number of pile head steel bars need to be bent, it is time-consuming and labor-intensive, and the bending quality of the pile head steel bars cannot be guaranteed, which seriously affects construction efficiency. Utility Model Content

[0004] In response to the above-mentioned deficiencies in the prior art, the utility model provides a bending angle control tooling for the pile head steel bars of bridge pile foundations, aiming to solve the problems of low bending efficiency and poor quality of the pile head steel bars, and the difficulty of the bending angle and opening size after bending to meet the design requirements.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] A tool for controlling the bending angle of steel bars at the pile head of a bridge pile foundation comprises a limit platform, which is arranged in a circular shape. A plurality of limit holes distributed in a ring are opened on the upper side of the limit platform. The limit holes are used to place the pile head steel bars to be bent. A positioning ring is provided above the limit platform. The median perpendicular line of the positioning ring coincides with the median perpendicular line of the limit platform. A plurality of evenly distributed support rods are fixedly connected to the lower side of the positioning ring.

[0007] Furthermore, a bottom plate is provided on the lower side of the limit platform, the bottom plate is circular, the mid-vertical line of the bottom plate coincides with the mid-vertical line of the limit platform, and a connecting rod fixedly connected to the support rod is provided on the circumferential side of the bottom plate.

[0008] With this structural design, the positions of the base plate and the limit platform are relatively fixed, and the bending of the pile head steel bars is more stable.

[0009] Furthermore, positioning grooves are provided at positions on the inner side of the positioning ring corresponding to the limiting holes, and the positioning grooves are arranged in an arc shape.

[0010] This structural design can support and position the bent pile head steel bars through the positioning groove, making it more stable.

[0011] Furthermore, the limiting platform is detachably connected to the base plate.

[0012] Furthermore, threaded holes are provided at the centers of the limiting platform and the base plate, and the limiting platform is connected to the base plate via the threaded holes and bolts.

[0013] This structural design can replace damaged base plates and can also replace base plates of other specifications and sizes as needed.

[0014] Furthermore, the limiting holes distributed in an annular shape on the limiting platform are distributed in multiple annular shapes from the edge of the limiting platform to the center of the circle.

[0015] This structural design allows for selecting different loop limit holes to limit the bent pile head reinforcement bars according to needs, making it more applicable.

[0016] Furthermore, the support rod is an adjustable telescopic rod.

[0017] This structural design can flexibly adjust the height of the support rod according to needs, diversify the bending angle and opening size of the pile head steel bars, and make it more applicable.

[0018] Furthermore, the support rod and the limit platform are both provided with scale marking lines.

[0019] For such a structural design, the bending condition of the pile head reinforcement can be checked and calculated through the scale marking lines.

[0020] Furthermore, the number of the support rods is four.

[0021] Furthermore, handles are provided on both sides of the positioning ring.

[0022] This structural design makes it easier to carry and transport.

[0026] This invention accurately detects the surface quality of ingots, effectively resolving quality issues such as ingot milling machine jamming or cutter damage caused by excessively thick ingot surfaces, or unremoved scale or casting defects caused by localized depressions on the ingot surfaces. This significantly reduces failure frequency and spare parts costs, avoids batch quality incidents, and effectively improves the production efficiency of ingot milling machines, achieving relatively ideal results.
