Description

Technical Field

[0001] The invention relates to the technical field of anchors, in particular to a prestressed porous anchor. Background Art

[0002] Prestressed concrete is to avoid the premature appearance of cracks in reinforced concrete structures, make full use of high-strength prestressed tendons and high-strength concrete, and try to reduce the tensile stress of the components by applying external force before the concrete structure or components are subjected to the use load, or even the concrete components under the compressive stress state. The production methods of prestressed concrete generally include pre-tensioning and post-tensioning. Since the post-tensioning method has lower requirements for production equipment and sites, it is widely used in general industrial and civil construction sites.

[0003] Prestressed anchor refers to the permanent anchoring device used in prestressed concrete. It is an anchoring tool used in post-tensioned structures or components to maintain the tension of prestressed tendons and transfer it to the interior of the concrete. During use, prestressed anchors generally need to be used in conjunction with corresponding anchor clips.

[0004] The post-tensioning method generally uses prestressed tendons and prestressed anchors in combination. First, a concrete component is made, and corresponding holes are reserved in the component body according to the position of the prestressed tendons. After the concrete strength of the component reaches the specified strength, the prestressed tendons are inserted into the reserved holes for tensioning, and the tensioned prestressed tendons are anchored to the ends of the component by using anchors. The prestressing force of the prestressed tendons is transmitted to the concrete by relying on the anchors at the ends of the component, causing it to produce precompressive stress. Finally, cement slurry is poured into the holes to form a whole with the prestressed tendons and the concrete component. However, in the current post-tensioning construction process, the installation of the three-hole prestressed anchor and the installation of the corresponding anchor clips need to be performed manually by operators, which is inefficient and affects the efficiency of construction.

[0033] See also Figures 1 to 4 The present invention provides a prestressed porous anchor, and the technical solution is as follows:

[0034] A prestressed porous anchor, comprising:

[0035] An anchor body 1, on which three anchor holes 4 for passing prestressed tendons are evenly opened;

[0036] Also includes:

[0037] A clip installer is provided on the anchor body 1 for installing the anchor clip.

[0038] When the prestressed tendons pass through the anchor holes 4, with the assistance of the clip installer, all the anchor clips are installed on the anchor at the same time, saving the time for installing the anchor clips and improving the construction efficiency.

[0039] As an embodiment of the present invention, refer to Figure 1 The clip installer includes a clip fixing ring arranged on the anchor body 1, a clip fixing plate is arranged inside the clip fixing ring, and the clip fixing plate and the clip fixing ring cooperate with each other.

[0040] When the prestressed tendon passes through the anchor hole 4, all the anchor clips close to the outer wall of the anchor body 1 are installed with the assistance of the clip fixing ring, and all the anchor clips close to the center side of the anchor body 1 are installed with the assistance of the clip fixing plate. Then, through the mutual cooperation relationship between the clip fixing ring and the clip fixing plate, the anchor clips close to the outer wall of the anchor body 1 and the anchor clips close to the center side of the anchor body 1 cooperate with each other and clamp the prestressed tendon together, so that all the anchor clips are installed on the anchor at the same time, saving the time of installing the anchor clips and improving the construction efficiency.

[0041] As an embodiment of the present invention, refer to Figure 1 The clip fixing plate is movably installed in the clip fixing ring, and the clip fixing plate and the clip fixing ring are connected by a buckle.

[0042] When the prestressed tendon passes through the anchor hole 4, the clip fixing plate is separated from the clip fixing ring. At this time, the anchor clip near the outer wall of the anchor body 1 is installed on the clip fixing ring, and the anchor clip near the center of the anchor body 1 is installed on the clip fixing plate. Then, by installing the clip fixing plate on the clip fixing ring, the function of installing all the anchor clips on the anchor at the same time is realized;

[0043] When the clip fixing plate is installed on the clip fixing ring, the clip fixing plate and the clip fixing ring are connected by a snap buckle, so that the clip fixing plate is now fixed on the clip fixing ring by the snap buckle, ensuring the stable fit between the clip fixing plate and the clip fixing ring, and preventing the clip fixing plate from loosening or falling due to external force, which may cause the anchor clip to loosen or fall off.

[0044] As an embodiment of the present invention, refer to Figure 1 and Figure 2 as well as Figure 5The clip fixing ring includes a clip limiting ring 2 fixedly connected to the upper surface of the anchor body 1, and a plurality of clip limiting grooves 23 are evenly opened on the inner side wall of the clip limiting ring 2. A guide groove 20 is correspondingly opened in the wall surface of each clip limiting groove 23 away from the center of the anchor body 1. A spring 5 is fixedly installed at the bottom end of the guide groove 20. A push rod 6 is movably installed in each guide groove 20, and the push rod 6 cooperates with the guide groove 20. A spring 5 is fixedly installed at the bottom end of the push rod 6, and the spring 5 is fixedly installed at the bottom end of the guide groove 20. A limiting boss 21 is fixedly installed on the wall surface of each push rod 6 near the center of the anchor body 1, and a plurality of boss holes 22 are opened on the inner wall of each clip limiting groove 23. Each boss hole 22 is connected with the guide groove 20 at the end away from the anchor body 1, and each boss hole 22 cooperates with the limiting boss 21. Each clip limiting groove 23 is symmetrically fixed with two clamping blocks 19 on the inner wall surface above the clip limiting ring 2, and the two clamping blocks 19 do not block the movement of the prestressed tendons.

[0045] When the prestressed tendon passes through the anchor hole 4, the side of the prestressed tendon close to the outer wall of the anchor body 1 falls into the clip limiting groove 1 23. At this time, the anchor clip close to the outer wall of the anchor body 1 is installed from above the clip limiting groove 1 23, so that the outer wall of the anchor clip away from the center of the anchor body 1 contacts the side wall surface of the limiting boss 21 close to the center of the anchor body 1, and the side wall surface of the anchor clip close to the center of the anchor body 1 contacts the side wall surface of the two clamping blocks 2 19 away from the center of the anchor body 1. At this time, the upper side wall of the limiting boss 21 contacts the top wall of the boss hole 22, and the anchor clip continues to be pressed downward. The limiting boss 21 moves downward, driving the push rod 6 to move downward, and the push rod 6 squeezes the spring 1 5. When the anchor clip moves downward a certain distance, the anchor clip When the height of the top wall is lower than the height of the bottom ends of the two clamping blocks 19, the two clamping blocks 19 no longer limit the horizontal movement of the anchor clip. At this time, the spring 15 rebounds, and the anchor clip is acted upon by the limiting boss 21 in the clip limiting groove 23, and moves toward the center of the anchor body 1. The inner wall surface of the anchor clip close to the center of the anchor body 1 contacts the wall surface of the prestressed tendon away from the center of the anchor body 1, and the top end of the anchor clip contacts the bottom ends of the two clamping blocks 19. At this time, under the joint action of the limiting boss 21, the two clamping blocks 19 and the prestressed tendon, the anchor clip close to the outer wall of the anchor body 1 is restricted in the clamp limiting groove 23, thereby completing the installation of the anchor clip close to the outer wall of the anchor body 1.

[0046] As an embodiment of the present invention, refer to Figure 1 and Figure 2 as well as Figure 5The clip fixing plate includes a clip limiting plate 3 arranged on the anchor body 1, and the clip limiting plate 3 cooperates with the clip limiting ring 2, and a plurality of clip limiting grooves 24 are evenly opened on the side wall of the clip limiting plate 3, and each clip limiting groove 24 cooperates with the clip limiting groove 1 23, and each clip limiting groove 24 is symmetrically fixedly installed with two clamping blocks 18 near the upper side wall of the clip limiting plate 3, and the two clamping blocks 18 do not block the movement of the prestressed tendon, a blind hole 12 is opened at the center of the top of the clip limiting plate 3, a pressing platform 15 is arranged in the blind hole 12, and the pressing platform 15 cooperates with the blind hole 12, and a limiting boss 10 is arranged on the side wall of each clip limiting groove 24 near the center of the anchor body 1.

[0047] The press platform 15 is composed of a lower extension part and an upper extension part. The lower extension part cooperates with the blind hole 12 so that the lower extension part can move in the vertical direction in the blind hole 12, thereby enabling the press platform 15 to move in the corresponding vertical direction. By manually pushing the upper extension part, the press platform 15 can rotate relative to the center of the clamping plate 3. By manually pressing the top of the press platform 15, the press platform 15 can move downward.

[0048] When the anchor clip is not installed in the clip limiting groove 24, the limiting boss 10 is in an ejected state, and the limiting boss 10 can shrink toward the center of the anchor body 1 when a force is applied to the wall surface of the side away from the center of the anchor body 1;

[0049] When the clip fixing plate is separated from the clip fixing ring, the protruding part of the pressure platform 15 is not located above the clip limiting groove 24, and the pressure platform 15 does not block the anchor clip from entering the clip limiting groove 24 from above. At this time, the anchor clip close to the center of the anchor body 1 is installed from above the clip limiting groove 24. At this time, the side wall of the anchor clip away from the center of the anchor body 1 contacts the side wall of the two clamping blocks 18 close to the center of the anchor body 1, and the lower wall of the anchor clip close to the center of the anchor body 1 contacts the side wall of the limiting boss 10 away from the center of the anchor body 1. The pressing platform 15 is rotated at this time so that the protruding part of the pressing platform 15 is located above the second clip limiting groove 24, and the pressing platform 15 blocks the anchor clip from escaping from the second clip limiting groove 24 from above, and the side wall surface of the anchor clip away from the center of the anchor body 1 and the side wall surface of the two clamping blocks 18 close to the center of the anchor body 1 are still in contact with each other. Through the joint action of the pressing platform 15, the two clamping blocks 18 and the limiting boss 10, the position of the anchor clip is limited in the second clip limiting groove 24, so as to prepare for the installation of multiple anchor clips at one time;

[0050] When the anchor clip on the side close to the center of the anchor body 1 is restricted in the clip limiting groove 24, the clip fixing plate is installed into the inside of the clip fixing ring, and the clip limiting groove 1 23 and the clip limiting groove 24 cooperate with each other. At this time, the top of the pressing platform 15 is pressed downward to make the pressing platform 15 move downward. The pressing platform 15 presses the anchor clip downward, and the limiting boss 10 shrinks toward the center of the anchor body 1. When the anchor clip drops to a certain height, the height of the top of the anchor clip is lower than the height of the bottom of the two clamping blocks 18, and the two clamping blocks 18 no longer restrict the anchor clip. During the horizontal movement, the limiting boss 10 is not subjected to stress and returns to the ejected state, ejecting the anchor clip toward the prestressed tendon and pressing the anchor clip onto the prestressed tendon. At this time, the wall surface of the anchor clip away from the center of the anchor body 1 contacts the wall surface of the prestressed tendon close to the center of the anchor body 1. Under the joint action of the limiting boss 10, the two clamping blocks 18 and the prestressed tendon, the position of the anchor clip close to the center of the anchor body 1 is limited in the clamp limiting groove 24, thereby completing the installation of the anchor clip close to the center of the anchor body 1.

[0051] As an embodiment of the present invention, refer to Figure 2 and Figure 3 A through hole is provided at the center of the top of the pressing platform 15, in which a pressing rod 13 is movably installed, and the pressing rod 13 cooperates with the through hole, and a limiting platform 16 is fixedly installed on the pressing rod 13, and a plurality of limiting grooves 14 are provided on the pressing platform 15, and the plurality of limiting grooves 14 cooperate with the limiting platform 16.

[0052] When the clip fixing plate is installed inside the clip fixing ring, the pressure rod 13 is pulled out. When the height of the bottom end of the limit platform 16 is higher than the height of the top end of the pressure platform 15, the pressure rod 13 is rotated to rotate the limit platform 16 to the top of the pressure platform 15. At this time, the pressure rod 13 is pressed downward to make the limit platform 16 press the top end of the pressure platform 15, so that the anchor clips in each clip limit groove 24 are installed.

[0053] When there is no need to press the top of the pressing platform 15, the multiple limit grooves 14 cooperate with the limit platform 16 to make the limit platform 16 contact with the bottom ends of the multiple limit grooves 14, and the bottom ends of the multiple limit grooves 14 are all flush with the top height of the clip limit plate 3. At this time, the pressure rod 13 is pressed downward, and the pressure on the pressure rod 13 will be directly transmitted to the clip limit plate 3, so that the pressing platform 15 is not subject to force, so that the pressing platform 15 cannot be pushed by the pressure rod 13 at this time, preventing the pressure rod 13 from being triggered by the thrust required for the installation process during the installation of the clip fixing plate into the inside of the clip fixing ring, causing the anchor clip installed on the clip fixing plate to fall out of the clip limit groove 24.

[0054] As an embodiment of the present invention, refer to Figure 2 and Figure 4 as well as Figure 5A limiting rod groove 11 is formed at the bottom end of the pressure rod 13, and a limiting rod 8 is fixedly connected to the bottom end of the blind hole 12, and the limiting rod 8 and the limiting rod groove 11 cooperate with each other.

[0055] By providing the limiting rod groove 11 and the limiting rod 8, the limiting rod groove 11 cannot be separated from the limiting rod 8, thereby preventing the pressure rod 13 from escaping from the blind hole 12, and assisting in limiting the movement direction of the pressure rod 13, thereby improving the reliability of the overall equipment.

[0056] As an embodiment of the present invention, refer to Figure 2 and Figure 3 A sleeve 17 is sleeved on the pressure rod 13, and the sleeve 17 is located below the pressure platform 15. The lower end of the sleeve 17 is fixedly connected to a spring 27, and the other end of the spring 27 is fixedly connected to the bottom end of the blind hole 12.

[0057] When installing the anchor clip near the center of the anchor body 1, the sleeve 17 pushes out the pressure platform 15 under the action of spring 27. At this time, the limit platform 16 cooperates with multiple limit grooves 14 under the action of gravity, and the limit platform 16 falls into each limit groove 14 to ensure the cooperation between the limit platform 16 and each limit groove 14, thereby preventing the anchor clip installed on the clip fixing plate from falling out of the clip limit groove 24 due to the accidental triggering of the pressure rod 13 during the installation of the anchor clip.

[0058] As an embodiment of the present invention, refer to Figure 2 and Figure 3 as well as Figure 5 Each limiting boss 10 is fixedly mounted on the outer wall of the sleeve 17, and a boss hole 9 is opened on the wall surface of each clip limiting groove 24 on the side close to the pressure rod 13, and each boss hole 9 cooperates with the limiting boss 10, and the clip limiting groove 1 23 cooperates with the clip limiting groove 2 24 to form a clip installation hole for installing the anchor clip.

[0059] During the process of installing the anchor clip on the side close to the center of the anchor body 1, when the anchor clip has fallen into the clip limiting groove 24, the protruding part of the pressing platform 15 is located above the clip limiting groove 24, and the pressing platform 15 prevents the anchor clip from escaping from the clip limiting groove 24 from above. The top of the limiting boss 10 contacts the top wall of the boss hole 9. At this time, the top of the pressing platform 15 is pressed, and each limiting boss 10 moves downward, realizing the function of the limiting boss 10 contracting toward the center of the anchor body 1 when subjected to force. At the same time, the sleeve 17 moves downward, and the sleeve 17 squeezes the spring 27, so that the spring 27 is compressed. When the anchor clip drops to a certain height due to the pressing, the height of the top of the anchor clip is lower than The height of the bottom ends of the two clamping blocks 18 is such that the two clamping blocks 18 no longer limit the horizontal movement of the anchor clip. At this time, the sleeve 17 drives the limiting boss 10 to be pushed upward under the action of the spring 27. The limiting boss 10 pushes the anchor clip toward the direction close to the prestressed tendon and presses the anchor clip onto the prestressed tendon. At this time, the wall surface of the anchor clip away from the center of the anchor body 1 contacts the wall surface of the prestressed tendon close to the center of the anchor body 1. Under the joint action of the limiting boss 10, the two clamping blocks 18 and the prestressed tendon, the position of the anchor clip close to the center of the anchor body 1 is limited in the clip limiting groove 24, thereby completing the installation of the anchor clip close to the center of the anchor body 1.

[0060] As an embodiment of the present invention, refer to Figure 1 The second clamping block 19 is a wedge-shaped block, and the first clamping block 18 and the second clamping block 19 cooperate with each other.

[0061] By setting the second clamping block 19 as a wedge-shaped block and making the second clamping block 19 cooperate with the first clamping block 18, the positioning of the clip fixing plate is more accurate during the installation process inside the clip fixing ring, which simplifies the installation process of the clip fixing plate and improves the construction efficiency.

[0062] Working principle: when the prestressed tendon passes through the anchor hole 4, the side of the prestressed tendon close to the outer wall of the anchor body 1 falls into the clip limiting groove 1 23. At this time, the anchor clip close to the outer wall of the anchor body 1 is installed from above the clip limiting groove 1 23, so that the side wall surface of the anchor clip away from the center of the anchor body 1 contacts the side wall surface of the limiting boss 21 close to the center of the anchor body 1, and the side wall surface of the anchor clip close to the center of the anchor body 1 contacts the side wall surfaces of the two blocks 2 19 away from the center of the anchor body 1. At this time, the upper side wall of the limiting boss 21 contacts the top wall of the boss hole 22, and the anchor clip continues to be pressed downward. The limiting boss 21 moves downward, driving the push rod 6 to move downward, and the push rod 6 squeezes the spring 1 5. When the anchor clip moves downward a certain distance, the anchor When the height of the top wall of the anchor clip is lower than the height of the bottom ends of the two clamping blocks 219, the two clamping blocks 21 no longer limit the horizontal movement of the anchor clip. At this time, the spring 15 rebounds, and the anchor clip is acted upon by the limiting boss 21 in the clip limiting groove 13, and moves toward the center of the anchor body 1. The side wall surface of the anchor clip close to the center of the anchor body 1 contacts the side wall surface of the prestressed tendon away from the center of the anchor body 1, and the top end of the anchor clip contacts the bottom ends of the two clamping blocks 219. At this time, under the joint action of the limiting boss 21, the two clamping blocks 219 and the prestressed tendon, the anchor clip close to the outer wall portion of the anchor body 1 is restricted in the clip limiting groove 123, and the installation of the anchor clip close to the outer wall portion of the anchor body 1 is completed.When the clip fixing plate is separated from the clip fixing ring, the protruding part of the pressing platform 15 is not located above the clip limiting groove 24, and the pressing platform 15 does not block the anchor clip from entering the clip limiting groove 24 from above. At this time, the anchor clip close to the center of the anchor body 1 is installed from above the clip limiting groove 24. At this time, the side wall of the anchor clip away from the center of the anchor body 1 contacts the side wall of the two clamping blocks 18 close to the center of the anchor body 1, and the lower wall of the anchor clip close to the center of the anchor body 1 contacts the side wall of the limiting boss 10 away from the center of the anchor body 1. At this time, the pressing platform 15 is rotated so that the protruding part of the pressing platform 15 is located above the clip limiting groove 24. Above the clip limiting groove 24, the pressing platform 15 prevents the anchor clip from escaping from the clip limiting groove 24 from above, and the wall surface of the anchor clip away from the center of the anchor body 1 and the wall surface of the two clamping blocks 18 close to the center of the anchor body 1 are still in contact. Through the joint action of the pressing platform 15, the two clamping blocks 18 and the limiting boss 10, the position of the anchor clip is limited in the clip limiting groove 24, so as to prepare for the installation of multiple anchor clips at one time. When the anchor clip close to the center of the anchor body 1 is limited in the clip limiting groove 24, the clip fixing plate is installed inside the clip fixing ring, and The clip limit groove 1 23 and the clip limit groove 2 24 cooperate with each other. At this time, the pressure rod 13 is pulled out. When the height of the bottom end of the limit platform 16 is higher than the height of the top end of the pressure platform 15, the pressure rod 13 is rotated to rotate the limit platform 16 to the top of the pressure platform 15. At this time, the pressure rod 13 is pressed downward to make the limit platform 16 press the top end of the pressure platform 15. Each limit boss 10 moves downward and the sleeve 17 moves downward at the same time. The sleeve 17 squeezes the spring 27 so that the spring 27 is compressed. When the anchor clip is lowered to a certain height due to the pressing, the height of the top end of the anchor clip is lower than the height of the bottom ends of the two clamping blocks 18, and the two clamping blocks 18 no longer restrict The anchor clip moves in the horizontal direction. At this time, the sleeve 17 drives the limiting boss 10 to push upward under the action of the spring 27. The limiting boss 10 pushes the anchor clip toward the direction close to the prestressed tendon and presses the anchor clip on the prestressed tendon. At this time, the wall surface of the anchor clip away from the center of the anchor body 1 contacts the wall surface of the prestressed tendon close to the center of the anchor body 1. Under the joint action of the limiting boss 10, the two clamping blocks 18 and the prestressed tendon, the position of the anchor clip close to the center of the anchor body 1 is limited in the clip limiting groove 24, completing the installation of the anchor clip close to the center of the anchor body 1.
