Background
In the hydraulic tunnel construction process, different geology, hydrology condition have different tunnel section structural style, and wherein the door type is comparatively common. Because tunnel structure section size diverse, in order to guarantee tunnel lining construction quality, guarantee that the hole type after the construction is accomplished accords with the designing requirement, often need carry out jumbo size arch reinforcing bar processing, because this part reinforcing bar radian machining accuracy requires highly, can not produce with ordinary reinforcement processing machinery again, the quality of processing influences the construction quality great, consequently designs and studies simple and easy arch reinforcing bar mold processing and becomes the key for tunnel lining quality control. The utility model is specially used for processing and manufacturing arch-shaped reinforcing steel bars of the arch crown part.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides a simple processing die for large-size arched reinforcing steel bars, which is made of local materials, is convenient to manufacture, is not limited by fields and processing conditions, and can be repeatedly recycled.
The technical scheme adopted by the utility model is as follows: a large-size arch-shaped reinforcing steel bar simple processing die comprises an arch-shaped die, steel pipe frame support legs, a plurality of perforated supporting plates and positioning pins; the arch-shaped die is formed by bending I-steel through a bending machine, is of an arch structure, and can adjust the radian of the arch-shaped die according to the section sizes of the urban door openings of different hydraulic tunnels. The steel pipe frame support legs are welded on the arch-shaped die and used for supporting the arch-shaped die; the steel pipe frame support legs are formed by welding and fixed with the ground foundation. The perforated supporting plate is provided with an upper plate and a lower plate, the middle parts of the two plates are provided with holes slightly larger than the diameter of the positioning pins, a steel bar is clamped between the two plates during processing, and the perforated supporting plate is welded and fixed on the outer edge side of the arch-shaped mould; the positioning pin penetrates through the supporting plate with the holes and is used for positioning and locking the bending of the steel bars, so that the bending steel bars are prevented from rebounding.
Preferably, the distance between the positioning pin and the outer edge of the arch-shaped die is determined according to the specification and the size of the steel bar, and is generally controlled according to the diameter of the steel bar which is 1-2 mm larger.
Preferably, the positioning pin is a T-shaped flat head positioning pin.
Preferably, 16# I-steel is adopted as the I-steel.
Preferably, the steel tube frame support leg is made of DN100 steel tubes.
The working principle of the utility model is as follows:
when the on-site arched reinforcing steel bar is machined, one end of the reinforcing steel bar to be machined is manually placed on a perforated supporting plate located at the end of the arched mold, a T-shaped flat-head positioning pin is used for inserting the perforated supporting plate to fix the reinforcing steel bar, then the reinforcing steel bar is forcibly bent along the radian of the arched mold, the T-shaped flat-head positioning pin is used for fixing the reinforcing steel bar again when the reinforcing steel bar is bent for a certain distance, and then the steps are repeated to bend, fix and bend until the radian requirement of the designed arched reinforcing steel bar is met. Because the processing of the reinforcing steel bar has elastic deformation, the bending radius of the arch-shaped die needs to be adjusted through tests, and the geometric dimension of the processed reinforcing steel bar is ensured to meet the radian requirement.
The utility model has the beneficial effects that:
1. the method is simple to manufacture, is not limited by sites and processing conditions, is simple and convenient to process the arched reinforcing steel bars, is safe and reliable, does not need special technical training, can be repeatedly recycled for many times, can well solve the problems of precision and quality of on-site large-size arched reinforcing steel bar processing when being used in tunnel engineering with smaller scale, is favorable for accelerating the construction progress and reducing the engineering cost.
2. The utility model has convenient assembly and disassembly, no need of maintenance and durability.
