Description

Technical Field

[0001] This invention relates to the field of steel tie rod construction technology, specifically to a steel tie rod embedded part installation and positioning device. Background Technology

[0002] In the construction of concrete beams, it is often necessary to pre-embed steel tie rods. The steel tie rods need to be partially embedded in the concrete in advance so that they can serve as load-bearing components after the concrete hardens, for subsequent structural connections, tensioning, or anchoring. The installation accuracy directly affects the safety and load-bearing performance of the beam structure. The positioning and fixing of the steel tie rods are completed before the beam concrete has solidified, in order to ensure that the anchorage end position, angle, and centerline of the steel tie rods are accurate after the beam is formed.

[0003] After the beam reinforcement cage is tied and before the concrete is poured, the steel tie rod is usually fixed by tying temporary support bars or simple positioning brackets. This method has problems such as inaccurate positioning benchmark, difficulty in effectively restraining lateral and longitudinal displacement, and insufficient anti-disturbance ability of the device itself, which makes it difficult to guarantee the installation position, tilt angle and anchorage position accuracy of the steel tie rod. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up a positioning base, a main positioning component, a lateral positioning plate, an end positioning plate, and anchoring steel bars, uses the positioning base and anchoring steel bars to fix the positioning device to the construction surface, preventing the positioning device from shifting due to external disturbances during the pouring of the crossbeam.

The lateral positioning plate fits tightly against both sides of the steel tie rod, constraining the lateral displacement and rotation of the steel tie rod end.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 A steel tie rod embedded part installation and positioning device includes: steel tie rod embedded part 1, positioning base, main positioning component 4, lateral positioning plate 5, end positioning plate 6 and anchoring steel bar 7. The positioning base 2 is located at the tail end of the steel tie rod embedded part 1. An anchoring hole 3 is opened on the positioning base 2. The anchoring steel bar 7 is inserted into the anchoring hole 3. The anchoring steel bar 7 is made of L-shaped steel bar. In one specific embodiment, the positioning base 2 includes a main channel steel 21 and two short channel steels 22. The two short channel steels 22 are respectively connected to both sides of the main channel steel 21 to form a support structure. Anchor holes 3 are opened on the short channel steels 22. The short channel steels 22 are perpendicular to the main channel steel 21. The two short channel steels 22 are symmetrically arranged on both sides of the main channel steel 21, and the ends of the short channel steels 22 are welded to the surface of the main channel steel 21. The main positioning component 4 is located inside the positioning base 2, below the steel tie rod embedded part 1, and is used to support the steel tie rod embedded part 1; In one specific embodiment, the main positioning component 4 includes: a support frame 41, a fixed base 47, and a push plate 44. The support frame 41 is connected inside the positioning base 2. A limiting groove 9 is formed on the positioning base 2. Limiting blocks 10 are provided on both sides of the support frame 41. The limiting blocks 10 are slidably connected to the inner wall of the limiting groove 9. When the support frame 41 is adjusted along the length direction of the steel tie rod embedded part 1, the limiting blocks 10 slide on the inner wall of the limiting groove 9 to guide the support frame 41. A bracket 42 is connected to the inner wall of the support frame 41. The inner wall of the bracket 42 is connected to the surface of the steel tie rod embedded part 1. Supporting pivots 46 are provided on both sides of the bracket 42. Through holes are provided on both sides of the support frame 41, and the inner wall of the through holes is connected to the surface of the steel tie rod embedded part 1. The surface connection of the support shaft 46 allows the bracket 42 to rotate around the support shaft 46, thereby changing the support angle of the steel tie rod embedded part 1. The inner wall of the support frame 41 is provided with multiple first reinforcing ribs 8 to enhance the rigidity of the support frame 41. The fixed seat 47 is provided with a telescopic top rod 43. The push plate 44 is connected to the support frame 41, and a connecting seat 45 is installed on the push plate 44. The telescopic end of the telescopic top rod 43 is connected to the inner wall of the connecting seat 45. The telescopic end of the telescopic top rod 43 drives the push plate 44 to move through the connecting seat 45. The push plate 44 drives the support frame 41 to adjust the support position. The telescopic top rod 43 can be a manual screw jack, a hydraulic cylinder, or an electric push rod.

[0021] Multiple lateral positioning plates 5 are provided on the positioning base 2 and located on the side of the end of the steel tie rod; In one specific embodiment, the connecting plate 13 is provided with an internally threaded sleeve 14, and a limit rod 15 is threadedly connected to the inner wall of the internally threaded sleeve 14. One end of the limit rod 15 is inserted into the inner wall of the limit hole 12. Each lateral positioning plate 5 has a limiting hole 12. A connecting plate 13 is provided on the side of the main channel steel 21. Specifically, the connecting plate 13 is welded to the corresponding position on the side of the main channel steel 21. An internal threaded sleeve 14 is fixed on the connecting plate 13. A limiting rod 15 is threaded into the internal threaded sleeve 14. Its end can be inserted into the limiting hole 12 of the lateral positioning plate 5 to fix the position of the lateral positioning plate 5. The lateral positioning plate 5 is inserted into the gap between the steel tie rod embedded part 1 and the main channel steel 21 to clamp the position of the steel tie rod embedded part 1 and constrain the lateral displacement of the steel tie rod embedded part 1. The end positioning plate 6 is located at the tail end of the steel tie rod and is used to limit the tail end of the steel tie rod embedded part 1. The end positioning plate 6 is connected to the positioning base 2 and the inner wall of the main channel steel 21. The end positioning plate 6 is provided with multiple second reinforcing ribs 11. The second reinforcing ribs 11 are made of triangular steel plates and are welded to the connection node between the end positioning plate 6 and the main channel steel 21 to form a triangular structure for stable support of the end positioning plate 6.

[0022] In a specific construction example, the positioning device is used according to the following steps: First, the installation area of ​​the steel tie rod positioning device is leveled and compacted to ensure that the installation surface meets the design elevation requirements. Then, according to the design drawings, the center position of the positioning device and the installation axis of the steel tie rod embedded part 1 are laid out using a total station, and the installation position and direction control line of the positioning base 2 are marked on the ground.

[0023] The steel tie rod positioning device is hoisted to the layout position. The position and direction of the device are adjusted according to the ground control line. After the adjustment is in place, the anchoring steel bar 7 is passed through the reserved anchoring holes 3 on the short channel steel 22 on both sides of the positioning base 2. The anchoring steel bar 7 is driven into the ground soil by hammering or vibration to make the device reliably anchored to the ground. After the installation is completed, the elevation and center position of the positioning device are checked.

[0024] The steel tie rod embedded part 1 is lifted off the ground and kept stable using a gantry. The direction of the steel tie rod is adjusted manually, and the embedded section of the steel tie rod embedded part 1 is slowly inserted into the embedded area of ​​the crossbeam. The steel tie rod embedded part 1 is reinforced and fixed within the embedded area of ​​the crossbeam using bundled reinforcing bars 16. After the embedded section of the steel tie rod embedded part 1 is inserted into the designed position, the tail end of the steel tie rod embedded part 1 is slowly lowered, allowing it to slowly enter the main channel steel 21. Its rod body is placed on the bracket 42 of the main positioning component 4. The lowering continues until the tail end of the steel tie rod embedded part 1 contacts the end positioning plate 6. The telescopic top rod 43 is operated to extend or retract its telescopic end, and the push plate 44 drives the entire support frame 41 within the limiting groove 9. Fine-tuning, or more preferably, since the bracket 42 can rotate around the support shaft 46, the extension and retraction of the telescopic top rod 43 will directly change the point of force application of the push plate 44 on the bracket 42, thereby causing the bracket 42 to drive the steel tie rod embedded part 1 to rotate around the support shaft 46, and thus accurately support it according to the design tilt angle of the steel tie rod embedded part 1. At the same time, it can ensure that the center line of the steel tie rod embedded part 1 coincides with the design axis. The lateral positioning plate 5 is inserted into the gap between the steel tie rod embedded part 1 and the main channel steel 21, clamping the position of the steel tie rod embedded part 1 and constraining the lateral displacement of the steel tie rod embedded part 1. The limiting rod 15 is rotated so that the end of the limiting rod 15 can be inserted into the limiting hole 12 of the lateral positioning plate 5, fixing the position of the lateral positioning plate 5.

[0025] Finally, the axial position, installation elevation, tilt angle and centerline deviation of the steel tie rod embedded part 1 were checked using a total station and a level. After confirming that there were no errors, concrete was poured. During the pouring process, since the device was firmly connected to the construction site through the anchoring steel bars 7, the steel tie rod embedded part 1 was subject to multiple constraints, which could effectively resist the disturbance caused by concrete impact and vibration.
