Description

Technical Field

[0001] This invention relates to the technical field of anchorages, and in particular to a detachable anchor plate and its manufacturing process and equipment. Background Technology

[0002] Anchor plates are a key component of the anchoring system in post-tensioned prestressed concrete structures. They are load-bearing steel plates located at the ends of the prestressing tendons (steel strands or reinforcing bars), between the working anchor ring and the concrete structure. Their core functions can be summarized in three points: 1. Stress transmission and dispersion (core function): Distribute the huge concentrated force (up to hundreds or even thousands of tons) transmitted by the anchor during tensioning evenly to the concrete member to prevent local crushing or cracking of the concrete.

[0003] 2. Provides anchoring position: The conical hole (anchor socket) on it provides precise positioning and support for the anchor ring (or wedge), ensuring a smooth and reliable anchoring process.

[0004] 3. Structural connection: It usually has grouting holes and venting holes to facilitate subsequent grouting operations in the ducts and ensure the bonding and corrosion protection between the prestressing tendons and the concrete.

[0005] Since grouting holes are generally located on the bearing surface of anchor plates, they can have an impact on the transmission and distribution of stress. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a detachable anchor plate and its manufacturing process and equipment, which has the advantage of high support strength.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A detachable anchor plate includes a flared body; the flared body has a wire hole, a grouting hole communicating with the wire hole, and an anchor ring mounting hole for installing an anchor ring, the anchor ring mounting hole communicating with the wire hole; it also includes a first support plate and a second support plate; the flared body is connected to the first support plate or to the second support plate; the first support plate is detachably connected to the flared body to connect a jack and block the entrance of the grouting hole; the second support plate is detachably connected to the flared body to increase the force application area on the concrete and block the entrance of the grouting hole; the area of ​​the second support plate is larger than the area of ​​the first support plate.

[0008] By adopting the above technical solution, both the first and second support plates are detachably connected to the bell-shaped body. This allows the first support plate to be removed during grouting to expose the grouting hole entrance, eliminating the need for machining grouting holes in the first support plate. This results in greater overall support strength and improves the load-bearing capacity of the jack. Furthermore, after grouting is complete, the first support plate can be removed and the second support plate installed. This allows the first support plate to be recycled, and the second support plate does not require any machining holes. Since the area of ​​the second support plate is larger than that of the first support plate, the area of ​​force application to the concrete is increased, resulting in more dispersed stress on the concrete and preventing stress concentration. Additionally, because the second support plate is detachable, a larger size can be selected as needed, further preventing stress concentration in the concrete.

[0009] Optionally, the flared mouth body has a connecting portion formed thereon; the anchor ring mounting hole is located on the connecting portion; the connecting portion has an external thread formed thereon; the first support plate and the second support plate both have threaded holes that mate with the connecting portion.

[0010] By adopting the above technical solution, compared with the method of connecting with several bolts, no positioning parts are needed during connection, and the operation is more convenient.

[0011] Optionally, each of the bell mouth bodies has several circumferentially evenly distributed support parts; the grouting hole is set on one of the support parts.

[0012] By adopting the above technical solution, in order to meet the size of the grouting hole, the size of the support part will be larger. In this way, multiple support parts with larger sizes can provide a larger support area for the first support plate when the jack applies force, thus avoiding pressure concentration and deformation of the first support plate.

[0013] Optionally, the first support plate includes a support plate body and a limiting seat; the limiting seat has a connecting stud that is threadedly connected to the support plate body and a connecting insert that mates with the inlet of the grouting hole.

[0014] By adopting the above technical solution, after the first support plate is installed in place, the front end of the connecting column is inserted into the grouting hole by rotating the limiting seat, thereby making the positions of the first support plate and the horn-shaped body more stable and avoiding accidental rotation and displacement of the jack during installation.

[0015] A manufacturing process for a detachable anchor plate includes the following steps: Step S100: Cast the bell mouth body, the first support plate, and the second support plate respectively; Step S200: Use a lathe to machine the anchor ring mounting hole of the flared mouth body and the inner cylindrical surface of the second support plate; Step S300: Use a surface machining lathe to simultaneously machine the planes that fit together when the flared mouth body and the second support plate are connected; Step S400: Use a lathe to machine the external thread of the connecting part, the internal thread of the first support plate, and the internal thread of the second support plate; Step S500: Use a tapping machine to process the connecting thread hole between the first support plate and the jack.

[0016] A production apparatus for a detachable anchor plate includes a planar machining lathe for simultaneously machining the planes that fit together when the flared body and the second support plate are connected.

[0017] By adopting the above technical solution, the planes that fit together when the flared mouth body and the second support plate are connected are simultaneously machined by a planar machining lathe, which improves the consistency of machining and thus improves the fit during operation.

[0018] Optionally, the planar machining lathe includes: A support fixture is used to simultaneously limit the flared mouth body and the second support plate, wherein the flared mouth body and the second support plate are coaxial and axially horizontally arranged. A rotation drive device is used to simultaneously drive the horn-shaped body and the second support plate to rotate; A tool drive device is used to simultaneously turn the planes that are in contact with each other when the flared mouth body and the second support plate are connected.

[0019] By adopting the above technical solution, the flared mouth body and the second support plate are installed on the support fixture. Then, the rotation drive device drives the flared mouth body and the second support plate to rotate simultaneously. Then, the tool drive device simultaneously turns the planes that fit together when the flared mouth body and the second support plate are connected. In this way, the corresponding planes of the flared mouth body and the second support plate are synchronously machined by rotating at the same speed and simultaneously feeding and retracting the tool, thereby improving the consistency of the machined planes.

[0020] Optionally, the support fixture includes: The main support shaft has a first limiting part that mates with the anchor ring mounting hole of the bell mouth body and a second limiting part that mates with the second support plate; The first limiting mechanism includes a first limiting movable seat, a first limiting rotating seat rotatably connected to the first limiting movable seat, and a first limiting drive component for driving the first limiting movable seat away from and towards the main support shaft. The second limiting mechanism is disposed on the second limiting part and includes a plurality of circumferentially evenly distributed second limiting components. The second limiting components include a radially movable pressing seat and a radial driving member for driving the pressing seat.

[0021] By adopting the above technical solution, the anchor ring mounting hole of the flared mouth body is positioned by the first limiting part, and then the first limiting mechanism causes the first limiting rotating seat, which is rotatably set, to abut against the flared mouth body to realize the installation of the flared mouth body. The second support plate is restricted by the second limiting part, and then all the pressing seats of the second limiting mechanism abut against the edge of the second support plate to realize the installation of the second support plate.

[0022] Optionally, the pressure seat includes a conical abutment surface.

[0023] By adopting the above technical solution, the pressure seat contacts the edge of the second support plate through a conical abutment surface, which can accommodate second support plates of different sizes and increase its applicability.

[0024] Optionally, the tool driving device includes: Tool support; A vertical drive mechanism for the tool is used to drive the tool support seat to move vertically up and down. The first cutting tool is horizontally slidably mounted on the cutting tool support seat and is used to turn the plane of the bell mouth body; The second cutting tool is horizontally slidably mounted on the cutting tool support seat and is used to turn the plane of the second support plate; A tool horizontal drive mechanism is mounted on the tool support seat to synchronously drive the first tool and the second tool to move horizontally.

[0025] By adopting the above technical solution, the vertical drive mechanism of the tool drives the tool support to move vertically up and down, thereby realizing radial tool advance and retraction. The horizontal drive mechanism of the tool drives the first tool and the second tool to move horizontally, thereby realizing axial tool advance and retraction. Attached Figure Description

[0037] The following is in conjunction with the appendix Figures 1-10 The present invention will be described in further detail below.

[0038] Example 1: A detachable anchor plate is disclosed, as shown in the reference. Figure 1 and Figure 3 The anchorage includes a bell-shaped body 10, a first support plate 20, and a second support plate 30. The bell-shaped body 10 is detachably connected to the first support plate 20 or the second support plate 30. The bell-shaped body 10 is embedded in concrete. When a jack is needed to apply tension to the steel strand, the first support plate 20 is connected to the bell-shaped body 10 and is used to connect the jack. After the tension setting is completed, the first support plate 20 is removed when grouting is required. After grouting is completed, the second support plate 30 is connected to the bell-shaped body 10. At this time, the second support plate 30 is used to apply force to the concrete. Finally, concrete is poured to seal the entire anchorage.

[0039] refer to Figure 1 , Figure 3 and Figure 4 The flared body 10 includes a flared tube 11, four circumferentially distributed support portions 12, and a connecting portion 13; the flared body 10 is integrally cast; the flared tube 11 has an axially penetrating wire hole 100; the connecting portion 13 is located at one axial end of the flared tube 11 and the two are coaxially arranged; one end of the wire hole 100 is open at the connecting portion 13 and is flared in shape; the connecting portion 13 has a coaxially arranged circular anchor ring mounting hole 102 for installing an anchor ring; the anchor ring mounting hole 102 communicates with the wire hole 100 and the anchor ring mounting hole 102 is connected to the wire hole 100. The diameter of 2 is greater than the maximum diameter of the wire hole 100; the end faces of all the support parts 12 near the connecting part 13 are flush with the end faces of the horn tube 11 connected to the connecting part 13; a grouting hole 101 communicating with the wire hole 100 is formed on the end face of one of the support parts 12 near the connecting part 13; the grouting hole 101 includes a horizontal part distributed parallel to the axial direction of the horn tube 11 and an inclined part from the outside to the inside away from its opening; one end of the inclined part communicates with the horizontal part and the other end communicates with the wire hole 100; in order to smoothly pour concrete, the connection between the horizontal part and the inclined part is rounded.

[0040] refer to Figure 1 , Figure 2 and Figure 5The first support plate 20 includes an annular support plate body 21. For easy assembly and disassembly, the support plate body 21 has internal threads, and the connecting portion 13 has external threads. During installation, the support plate body 21 is fitted onto and screwed onto the connecting portion 13. For connecting the jack, the support plate body 21 has four threaded connecting holes 212. After the first support plate 20 is installed, the threaded connecting holes 212 are spaced apart from the support portion 12, and the support plate body 21 blocks the entrance of the grouting hole 101, meaning the horizontal portion of the grouting hole 101 is away from the opening of the inclined portion. In other embodiments, the support plate body 21 and the flared mouth body 10 are connected by several bolts.

[0041] refer to Figure 1 , Figure 2 and Figure 5 To prevent accidental rotation of the support plate body 21 after installation, in other embodiments, the first support plate 20 further includes a limiting seat 22; the limiting seat 22 includes a connecting stud 222 and a connecting insert 221; the connecting stud 222 and the connecting insert 221 are coaxially connected; a receiving groove 211 for the connecting insert 221 to extend and retract is formed on the end face of the support plate body 21 near the support part 12; a coaxial through-hole 210 for the extension and retraction of the receiving groove 211 is formed on the side wall away from the support part 12; the connecting stud 222 is screwed into the extension and retraction hole 210; the connecting insert 221 cooperates with the inlet of the grouting hole 101. After the support plate body 21 is installed in place, the connecting insert 221 can be inserted into the inlet of the grouting hole 101 by rotating the limiting seat 22, thereby preventing accidental rotation of the support plate body 21. For ease of operation, a hexagonal drive groove 220 is formed on the end face of the connecting stud 222 away from the connecting insert 221. When it is necessary to rotate the limit seat 22, an Allen wrench can be used to rotate it from the side of the support plate body 21 away from the flared mouth body 10, making the operation more convenient.

[0042] refer to Figure 1 , Figure 3 and Figure 6The second support plate 30 is annular and has internal threads that mate with the connecting part 13. To better distribute the stress applied to the concrete, the area of ​​the second support plate 30 is larger than that of the first support plate 20. Furthermore, the second support plate 30 has no holes, making its overall strength greater than that of a plate with holes, and allowing it to withstand greater stress. Additionally, to adapt to different working environments, the second support plate 30 can be manufactured in various specifications, differing only in its outer diameter. Moreover, to reduce the gap between the second support plate 30 and the flared mouth body 10, and to prevent concrete from entering this gap during concrete pouring and sealing, the surfaces where the flared mouth body 10 and the second support plate 30 meet are machined to improve their fit. The machined surfaces of the flared mouth body 10 include the flared tube 11 and the four supporting parts 12, which are flush with each other. Considering the actual usage, the area where the second support plate 30 is in contact with the horn mouth body 10 is much smaller than the area of ​​its end face near the horn mouth body 10. Therefore, it would be wasteful to process the entire end face of the second support plate 30 near the horn mouth body 10. So, the processing of the plane of the second support plate 30 only needs to process the annular area that covers the horn mouth body 10.

[0043] Example 2: A manufacturing process for a detachable anchor plate is disclosed, comprising the following steps: Step S100: Cast the horn mouth body 10, the first support plate 20, and the second support plate 30 respectively; Step S200: Use a lathe to machine the side walls of the anchor ring mounting hole 102 and the wire threading hole 100 of the flared mouth body 10, as well as the inner cylindrical surface of the second support plate 30. Step S300: Use a surface machining lathe to simultaneously machine the planes that fit together when the flared mouth body 10 and the second support plate 30 are connected; In step S400, the external thread of the connecting part 13, the internal thread of the first support plate 20, and the internal thread of the second support plate 30 are machined using a lathe. Step S500: Use a tapping machine to process the connecting thread hole 212 between the first support plate 20 and the jack.

[0044] Example 3: A production equipment for a detachable anchor plate is disclosed, including a planar machining lathe for simultaneously machining the planes that fit together when the flared body 10 and the second support plate 30 are connected; the planar machining lathe is referenced.

The support fixture 50 is used to simultaneously limit the flared mouth body 10 and the second support plate 30. The flared mouth body 10 and the second support plate 30 are coaxial and axially horizontal. The rotary drive device 60 is used to simultaneously drive the flared mouth body 10 and the second support plate 30 to rotate. The tool drive device 70 is used to simultaneously turn the planes that are in contact with each other when the flared mouth body 10 and the second support plate 30 are connected.

To connect the main support shaft 52, a first vertical plate 42 is connected to the upper end surface of the lathe base 40, and the rotatable connecting main shaft 521 horizontally passes through the first vertical plate 42 and the two are rotatably connected by several bearings.

During operation, the rotation drive servo motor 61 is started, and the main support shaft 52 is driven to rotate through the meshing drive active gear 63 and drive driven gear 62, thereby providing the rotational action required for turning the bell mouth body 10 and the second support plate 30.

[0050] refer to Figure 8 A second vertical plate 41 is connected to the upper surface of the lathe base 40. The first limit drive component 514 is a first limit drive electric cylinder, which is horizontally set and fixed on the second vertical plate 41. The first limit moving seat 511 is fixed on the piston rod of the first limit drive electric cylinder. The axial direction of the first limit rotating seat 513 is collinear with the axial direction of the main support shaft 52 and is rotatably connected to the first limit moving seat 511 through a pair of bearings. To ensure the stability and accuracy of the movement of the first limit moving seat 511, a pair of parallel linear guides 512 are connected between the upper surface of the lathe base 40 and the first limit moving seat 511; the direction of the linear guides 512 is parallel to the axial direction of the main support shaft 52. During the positioning and installation of the flared mouth body 10, the anchor ring mounting hole 102 of the flared mouth body 10 is first fitted onto the end of the first insertion portion of the first limiting portion 522. Then, the first limiting drive electric cylinder is activated, and the first limiting rotating seat 513 moves closer to the flared mouth body 10 until it abuts against the flared mouth body 10. In this way, the flared mouth body 10 is clamped by the first limiting rotating seat 513 and the first limiting portion 522. In other embodiments, the first limiting drive component 514 can also be other linear drive components.

[0051] refer to Figure 8 and Figure 9 The second limiting part 523 includes a circular plate-shaped second limiting plate 5231 and a cylindrical second limiting post 5232 coaxially formed on the end face of the second limiting plate 5231 away from the rotating connecting main shaft 521; the diameter of the second limiting post 5232 matches the inner diameter of the second support plate 30.

[0052] refer to Figure 8 and Figure 9The second limiting mechanism 53 cooperates with the second limiting pin 5232 to position and install the second support plate 30. The second limiting mechanism 53 includes four circumferentially distributed second limiting components. The second limiting components include a radially movable pressing seat 532 and a radial driving member 531 for driving the pressing seat 532. The second limiting plate 5231 is formed with four circumferentially distributed radial sliding grooves 5230 for the pressing seat 532 to slide radially. A radial guide rod 5233 is formed between a pair of opposite sidewalls of the radial sliding groove 5230. The radial driving member 531 is a radial driving electric cylinder. The radial driving electric cylinder is fixed on the rotating connecting main shaft 521 and the extension and retraction direction is radially arranged. The pressing seat 532 is fixedly connected to the piston rod of the radial driving electric cylinder on the corresponding side. When the second support plate 30 is positioned and installed, it is horizontally sleeved on the second limiting post 5232. Then, all the radial drive electric cylinders drive all the pressing seats 532 to move radially inward until all the pressing seats 532 clamp the second support plate 30. In other embodiments, the radial drive member 531 can also be other linear drive members. To accommodate the clamping of second support plates 30 of different sizes, the stroke of the radial drive member 531 is adjustable.

[0053] To improve the adaptability of the second limiting mechanism 53, the part of the pressure seat 532 facing the second support plate 30 is a conical abutment surface 5321, and the diameter of the abutment surface 5321 gradually increases along the direction close to the second limiting plate 5231. Since the area of ​​the second support plate 30 being machined is in the middle rather than the edge, the pressure seat 532 will not affect the movement of the tool in subsequent turning.
