Description

Technical Field

[0001] The utility model relates to a corrugated pipe positioning steel bar frame. Background Art

[0002] The corrugated pipe in precast beam and slab is mainly used for post-tensioning construction. Its main function is to protect the steel strands from being contaminated during concrete pouring and to ensure the quality of tensioning. After tensioning, grouting is carried out in the corrugated pipe according to the specified requirements to consolidate the steel strands in the pipe with the bridge to form an integral force to achieve the tensioning effect.

[0003] There are two ways to position traditional prestressed corrugated pipe steel bars: use a steel tape measure to confirm the corrugated pipe positioning points on the steel bar web skeleton according to the drawing, and after confirming the positioning points, use steel bars to weld into a # shape to fix the corrugated pipe; Method 2: Traditional corrugated pipe positioning steel bar cradles use welding to fix the positioning points. For example, in the beam and slab production process, the beam types produced are more and more complex. When the corrugated pipe positioning changes, the required corrugated pipe positioning cradles must also be equipped accordingly. Under normal circumstances, a pair of traditional corrugated pipe steel bar positioning cradles can only meet 1-2 two different beam types and corrugated pipe positioning. Therefore, the traditional structure is prone to cause too many cradles, the production process is complicated, and it is difficult for construction workers to distinguish. Utility Model Content

[0019] The present invention will be described in further detail below through specific embodiments with reference to the accompanying drawings.

[0020] like Figure 1-2 As shown, a corrugated pipe positioning steel bar tire frame includes an upper base 1, a lower base 2, and steel pipes 3 fixed side by side between the upper base 1 and the lower base 2. A positioning tire frame 4 is provided between every two adjacent steel pipes 3. The positioning tire frame 4 includes a front bracket 41 and a rear bracket 42. The centers of the front bracket 41 and the rear bracket 42 are both provided with a through hole 43. The through hole 43 is matched with a bolt 44 and a nut 45. The top of the front bracket 41 is fixed with a front positioning platform 46 that protrudes vertically forward. The left and right sides of the front positioning platform 46 are provided with a through hole 43. Corrugated pipe grooves 47 are left at the corresponding positions of the steel pipe 3 on both sides, and a rear positioning platform 48 that protrudes vertically backward is fixed on the top of the rear bracket 42. Corrugated pipe grooves 47 are left at the corresponding positions of the steel pipe 3 on the left and right sides of the rear positioning platform 48. The arrangement of the corrugated pipe grooves 47 creates a certain gap between the welding part between the corrugated pipe and the positioning steel bar and the front bracket 41, so that during welding, welding slag is not easy to fall onto the front bracket 41, avoiding the accumulation of welding slag on the front bracket 41 after repeated use, resulting in position deviation of the positioning steel bars thereon, thereby ensuring the accurate positioning of the positioning steel bars.

[0021] An arcuate groove 49 matching the steel pipe 3 is provided at the position where the rear side of the front bracket 41 meets the steel pipe 3 , and an arcuate groove 49 matching the steel pipe 3 is provided at the position where the front side of the rear bracket 42 meets the steel pipe 3 .

[0022] The arcuate groove 49 positions the tire frame 4 in the transverse direction. When the front bracket 41 and the rear bracket 42 are fastened by the bolts 44 and the nuts 45 , the front bracket 41 and the rear bracket 42 are located in the middle of two adjacent steel pipes 3 in the transverse direction.

[0023] The front bracket 41 and the front positioning platform 46, the rear bracket 42 and the rear positioning platform 48 are all made of angle iron. The angle iron processing allows the front bracket 41 and the front positioning platform 46, the rear bracket 42 and the rear positioning platform 48 to be integrally formed, thereby improving the strength of the positioning tire frame 4 and making it more convenient to process.

[0024] like Figure 3 As shown, the method of using the utility model is as follows:

[0025] 1. According to the needs of the precast beam slab, all the positioning brackets 4 are fixed to the target positions. The positioning brackets 4 are fixed as follows: first, the rear bracket 42 is placed on the rear side of the steel pipe 3, and the front bracket 41 is placed on the front side of the steel pipe 3. Then, the front bracket 41 and the rear bracket 42 are connected together with the bolts 44 and nuts 45. Then, the front bracket 41 and the rear bracket 42 are adjusted to the target position. Finally, the bolts 44 and nuts 45 are tightened to fix the positioning bracket 4 in the target position.

[0026] 2. Place the bent corrugated tube 5 in front of the steel tube 3 so that all longitudinal tubes of the corrugated tube 5 correspond to all steel tubes 3 one by one;

[0027] 3. Place the positioning steel bars 6 of the required length one by one on the top of the front positioning platform 46, and then weld the two ends of the positioning steel bars 6 to the steel pipes 3 on both sides respectively;

[0028] 4. Once all the positioning steel bars 6 are welded, the production of the corrugated pipe is completed.

[0029] Traditional corrugated pipe positioning cradles are welded with angle irons. There are 2-3 types of beam-type corrugated pipe positioning points on a corrugated pipe positioning steel cradle, resulting in many corrugated pipe positioning points on the cradle, which need to be colored to distinguish them, which can easily cause the corrugated pipe positioning to be inaccurate.

[0030] The positioning frame adopted by the utility model no longer fixes the positioning points of the frame by welding, but is fixed by bolts. The upper and lower positions of the positioning points of the corrugated pipe can be adjusted by adjusting the bolts, and the deviation of the corrugated pipe positioning can be corrected at any time. Corresponding adjustments can also be made for different beam types and different corrugated pipe positioning, which greatly reduces the investment in the number of corrugated pipe positioning frames, extends the service life of the positioning frames, saves project cost investment, improves the production efficiency of corrugated pipe positioning, and reduces the error rate of construction workers.

[0031] At present, the tire frame body is usually made of an angle iron structure, so its surface area is large. During welding, welding slag easily falls on the surface and accumulates, which can easily burn the tire frame and affect the service life of the tire frame. The tire frame body of the utility model is made of a steel pipe, which reduces the surface area, makes it difficult for welding slag to accumulate, and extends the service life.

[0032] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and is subject to numerous variations. All variations that can be directly derived or conceived by a person of ordinary skill in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
