Technical Field
[0001] The utility model relates to a corrugated pipe positioning steel bar processing tire frame, belonging to the technical field of tire frames. Background Art
[0002] Prestressing technology can reduce the tensile stress of concrete when it is loaded by applying prestressing stress in the bridge structure, thereby preventing cracks in the concrete. Prestressing technology can improve the tensile strength of the bridge structure, reduce the weight of concrete components, save the concrete materials used, and extend the service life of the bridge project. Prestressing technology can effectively improve the performance and safety of prefabricated beams during construction and use.
[0003] Among them, the prestressed steel strands used to apply and anchor prestressed force are passed through the corrugated tube. Therefore, whether the position of the corrugated tube is accurate is a key technical indicator of prestressed technology. The corrugated tube is positioned by the positioning steel bars of the prefabricated beam steel skeleton. The beam steel skeleton includes square stirrups and corrugated tube positioning bars transversely connected between the two long sides of the stirrups. The entire production process of the beam steel skeleton is on a horizontal surface. Workers need to bend over for a long time to work. The production process is inconvenient and the operation process is not user-friendly. At the same time, the positioning accuracy between the corrugated tube positioning bars and the square stirrups is difficult to guarantee. Utility Model Content

[0025] Please refer to Figure 1 to Figure 2 A corrugated tube positioning steel bar processing frame (hereinafter referred to as “processing frame”) shown in one embodiment of the present application includes a frame body 1, a fixing mechanism 2 and a positioning mechanism 3.
[0026] The frame 1 includes at least one working surface 11 which is at an acute angle to the vertical direction. The working surface 11 which is at an acute angle to the vertical direction is set on the frame 1, so that the stirrups 4 originally placed horizontally on the horizontal workbench can be placed at an angle, thereby reducing the need for operators to constantly move and bend when welding the corrugated pipe positioning ribs 5 in the length direction of the stirrups 4. The inclined working surface 11 can shorten the distance between different corrugated pipe positioning ribs 5 and the operators, avoiding unnecessary moving and bending, and making the operation process more humane.
[0027] In this embodiment, the frame 1 is an A-shaped structure, and two working surfaces 11 are formed on two symmetrical sides of the A-shaped structure. By setting the working surfaces 11 on the two symmetrical sides of the A-shaped structure, two operators can work at the same time, and because they are located on two symmetrical sides, the operators will not be affected by each other's welding work, thereby improving the utilization rate of the frame 1. Of course, in other embodiments, there can be multiple working surfaces 11, as long as the angle between the working surface 11 and the vertical direction is an acute angle, which is not specifically limited here.
[0028] Among them, the angle between the working surface 11 and the vertical direction is 10° to 30°. Within this angle range, the requirements of welding work of stirrups 4 and corrugated pipe positioning ribs 5 in the prior art are basically met. At the same time, the operators do not need to bend over to work, and the stirrups 4 and corrugated pipes are not easy to fall off when positioned and placed on the working surface 11.
[0029] The fixing mechanism 2 includes a plurality of fixing structures 21 arranged at intervals on the working surface 11 in the horizontal direction and a supporting structure 22 arranged at the bottom of the working surface 11. The supporting structure 22 supports the short side 42 of the stirrup 4, and at least one fixing structure 21 abuts against the long side 41 of the stirrup 4. When the stirrup 4 is placed on the working surface 11, the supporting structure 22 is supported on the short side 42 of the stirrup 4, so that the stirrup 4 can be inclined on the working surface. Since the fixing structure 21 is fixedly arranged, and the size of the stirrup 4 is different according to different construction requirements, when the width direction of the stirrup 4 is the same as that of the two adjacent fixing structures 21, the two adjacent fixing structures 21 respectively abut against the two long sides 41 of the stirrup 4 to fix the stirrup 4. If the width of the stirrup 4 is greater than or less than the width of the two adjacent fixing structures 21, the stirrup 4 is moved so that one long side 41 of the stirrup 4 abuts against the fixing structure 21, and the stirrup 4 is fixed in cooperation with the supporting structure 22. The number of the fixed structures 21 can be set according to the size of the working surface 11 and the size of the stirrups 4, and is not specifically limited here.
[0030] In other embodiments, at least one of the two adjacent fixing structures 21 is configured to be movable in the horizontal direction, so that the distance between the two adjacent fixing structures 21 can be changed to match different types of stirrups 4.
[0031] Since the stirrup 4 is relatively long, in order to prevent the stirrup 4 from shaking when placed on the working surface 11, two groups of fixing mechanisms 2 are provided. The two groups of fixing mechanisms 2 are arranged at intervals on the working surface 11, and the two groups of fixing mechanisms 2 are arranged symmetrically to ensure that there are two fixing structures 21 on one long side 41 of the stirrup 4 to abut and fix it.
[0032] Since the shape of the stirrups 4 includes a parallelogram, in order to adapt to stirrups 4 of different shapes, the fixed structure 21 includes at least one fixed block extending along a first direction, and the angle between the first direction and the inclination direction of the working surface 11 is between -30° and 30°. The fixed block is in the shape of an elongated strip, and the direction of the long side 41 of the stirrup 4 in the length direction of the fixed block is consistent, so as to maximize the contact area between the fixed block and the stirrup 4, so as to increase the friction between the two, thereby preventing the stirrup 4 from shaking. In addition, the fixed structure 21 is generally a fixed block, and is fixed by two fixed blocks against the two long sides 41 of the stirrup 4. Of course, each fixed structure 21 can also be two fixed blocks arranged at intervals, and the spacing between the two fixed blocks is the same as the diameter of the steel bar used to make the stirrup 4, and the long side 41 of the stirrup 4 is clamped and fixed by two stirrups 4, thereby fixing the stirrup 4.
[0033] A plurality of positioning mechanisms 3 are distributed on the working surface 11, and the projection of the positioning mechanism 3 along the inclined direction of the working surface 11 falls between the projections of two adjacent fixed structures 21. The positioning mechanism 3 is arranged between the two fixed structures 21, and the positioning mechanism 3 supports the bellows positioning rib 5 so that the two ends of the bellows positioning rib 5 abut against the two long sides 41 of the stirrup 4, which is convenient for positioning the welding position of the bellows positioning rib 5. The welding process also avoids the shaking of the bellows positioning rib 5, which causes the welding angle to deviate.
[0034] The positioning mechanism 3 is a positioning block extending in the horizontal direction, and at least one positioning block is arranged in the inclined direction of the working surface 11. In the inclined direction of the working surface 11, multiple positioning blocks are arranged between the two fixed structures 21 to meet the welding requirements of the same stirrup 4 welding the corrugated pipe positioning rib 5 at different positions.
[0035] In other embodiments, the positioning block can be configured to be movably installed. For example, two rows of mounting holes are set between two fixed structures 21 along the inclined direction of the working surface 11, and two fixed columns cooperating with the mounting holes are set on the positioning block. Through the cooperation between the fixed columns and the mounting holes, the position of the positioning block can be adjusted at will.
[0036] The positioning block is an L-shaped block, and the upper surface of the L-shaped block and the working surface 11 are surrounded to form a receiving groove for accommodating the bellows positioning rib 5. In order to prevent the bellows positioning rib 5 from sliding off the positioning block, the positioning block is set as an L-shaped block, and a receiving groove with openings on both sides and the top is formed by the L-shaped block and the working surface 11. During the welding process, the bellows positioning rib 5 is placed in the receiving groove, and the movement of the bellows positioning rib 5 can be avoided under the restriction of the L-shaped block and the working surface 11, thereby better improving the welding accuracy of the bellows positioning rib 5.
[0037] The supporting structure 22 is a strip support plate perpendicular to the working surface 11. A strip support plate perpendicular to the working surface 11 is arranged at the bottom of the working surface 11. Since the angle between the working surface 11 and the vertical direction is an acute angle, the angle between the strip support plate and the horizontal direction is also an acute angle. This can effectively ensure that when the short side 42 of the stirrup 4 is against the strip support plate, the short side 42 of the stirrup 4 is always close to the junction of the strip support plate and the working surface 11, thereby preventing the stirrup 4 from sliding off the edge of the strip support plate, thereby affecting the welding effect.
[0038] The present application sets at least one working surface with an acute angle to the vertical direction on the frame, so that the operators do not need to bend over for a long time when welding stirrups and corrugated pipe positioning bars, and the welding operation is more convenient and more humane. At the same time, the stirrups are fixed by a fixing mechanism, and the corrugated pipe positioning bars are supported and positioned by a positioning mechanism, which makes welding convenient for the operators and improves the welding accuracy between the corrugated pipe positioning bars and the stirrups.
[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
