Abstract

The present invention discloses an auxiliary construction device and a construction method for the wedge-shaped grip of a prestressed beam anchor. By using multiple extrusion rings to synchronously radially extrude the wedge-shaped grip blocks to lock multiple wedge-shaped grips of the anchor, the multiple wedge-shaped grips of the anchor are synchronously installed, which not only saves labor but also ensures the uniformity of the grip positions, improves the installation efficiency of the wedge-shaped grips of the anchor and reduces the rework rate, providing a guarantee for subsequent construction. At the same time, it is convenient to fix multiple wedge-shaped grips of the anchor and sleeve them on the prestressed cable (i.e., the steel strand). When the clamping device fixes the wedge-shaped grips of the anchor, the end face of the jacking sleeve is abutted against the end face of the wedge-shaped grip of the anchor, buffering and damping the hammering of the construction workers when the wedge-shaped grip of the anchor is tightened, and enabling each wedge-shaped grip to be evenly stressed, preventing the construction workers from hitting the wedge-shaped grip too hard and damaging it. The present invention solves the problems of low installation efficiency and unstable installation quality of the working wedge-shaped grips of the existing wedge-shaped grip type anchor for prestressed beams.

Description

[0039] The following further elaborates on the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the related invention and not for limiting the invention. Additionally, it should be noted that for ease of description, only the parts related to the invention are shown in the drawings.

[0040] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the drawings and embodiments.

[0041] Referring to Figures 1 to 11 As shown, the present invention provides an auxiliary construction device for the anchor clip of a prestressed beam, including: a locking disc 1, a pressing ring 2, a supporting disc 3, and a receiving box 4.

[0042] Among them, the locking disc and the supporting disc are coaxially arranged.

[0043] The locking disc 1 is provided with a plurality of first through holes a and a plurality of satellite holes. The first through holes a are used for the insertion or penetration of one end of the anchor clip 62. The plurality of satellite holes are arranged along the circumferential direction of the first through hole a. Referring to Figure 3 As shown, four satellite holes are arranged along the outer edge of each first through hole. The plurality of satellite holes are equidistantly arranged along the circumferential direction of the first through hole.

[0044] Combining Figure 4 and Figure 5 As shown, a plurality of wedge-shaped clamping blocks 11 are rotatably installed at one port of the first through hole a.

[0045] A pressing ring 2 is movably sleeved outside the plurality of wedge-shaped clamping blocks 11 at the port of each first through hole a.

[0046] The pressing ring 2 is connected with a push rod 21. The push rod 21 is movably inserted through the satellite hole and extends to the side of the locking disc 1 away from the wedge-shaped clamping block 11.

[0047] In this embodiment, the first perforation has a first end facing the support disc and a second end away from the support disc. The wedge-shaped clamping block is arranged at the port of the second end of the first perforation. The wedge-shaped clamping block has a first end and a second end in the length direction. The first end of the wedge-shaped clamping block is close to the locking disc, and the second end of the wedge-shaped clamping block is away from the locking disc. Initially, the extrusion ring is arranged at the first end of the wedge-shaped clamping block with a smaller thickness. After the extrusion ring slides along the axial direction of the first perforation towards the second end of the wedge-shaped clamping block with a larger thickness, the plurality of wedge-shaped clamping blocks close towards the axis direction of the extrusion ring. Correspondingly, when the extrusion ring slides towards the first end of the wedge-shaped clamping block again, the radial extrusion force of the extrusion ring on the plurality of wedge-shaped clamping blocks disappears.

[0048] In this embodiment, a limiting sleeve 12 is coaxially connected to the port of the second end of the first perforation a. A plurality of notches are formed on the side wall of the limiting sleeve 12 and arranged along the circumferential direction of the limiting sleeve 12. A fixed shaft is connected between the opposite inner walls of the notch. A shaft hole is formed in the middle of the wedge-shaped clamping block 11, and the fixed shaft is rotatably arranged in the shaft hole. The thickness of the wedge-shaped clamping block is greater than the thickness of the side wall of the limiting sleeve.

[0049] As a preferred embodiment, the wedge-shaped clamping block 11 has a first end and a second end opposite in the axial direction of the limiting sleeve 12, and the thickness of the wedge-shaped clamping block 11 gradually increases from the first end of the wedge-shaped clamping block 11 to the second end of the wedge-shaped clamping block 11.

[0050] Furthermore, the wedge-shaped clamping block 11 has an inner side facing the anchor clip 62 and an outer side facing away from the anchor clip 62. The outer side of the wedge-shaped clamping block 11 is concave in an arc shape. The thickness of the wedge-shaped clamping block gradually increases from the top of the arc surface towards the first end and the second end of the wedge-shaped clamping block, and the thickness of the first end of the wedge-shaped clamping block is less than the thickness of the second end of the wedge-shaped clamping block.

[0051] In some embodiments, an arc-shaped abutting top surface is formed on one side of the first end of the wedge-shaped clamping block facing the axis direction of the extrusion ring, and the arc-shaped abutting top surface is coaxially arranged with the fixed shaft.

[0052] As a preferred embodiment, a plurality of anti-slip convex ribs 111 are connected to the inner side of the wedge-shaped clamping block 11 and arranged along the length direction of the wedge-shaped clamping block 11. In this embodiment, the anti-slip convex ribs are rubber convex ribs.

[0053] The support disc 3 and the locking disc 1 are arranged opposite to each other. The support disc is connected to a plurality of push rods 21 on the locking disc 1. A tie rod 31 is detachably installed between the support disc 3 and the locking disc 1. The support disc 3 is provided with a plurality of second perforations. A jacking sleeve 32 for prestress to pass through is arranged in the second perforations. The jacking sleeve 32 is movably arranged in the first perforation a.

[0054] After the wedge-shaped clamping blocks 11 at the port where the anchor jaw 62 is inserted into the first through hole a, the tie rod 31 is tied between the support plate 3 and the locking plate 1 to make the push rod 21 push against the extrusion ring 2, and the push sleeve 32 abuts against the end of the anchor jaw 62. The extrusion ring 2 closes the plurality of wedge-shaped clamping blocks 11 to make the plurality of wedge-shaped clamping blocks 11 clamp the anchor jaw 62.

[0055] In this embodiment, refer to Figures 3 to 5 , one end of the tie rod 31 is fixedly connected to the locking plate 1. The support plate 3 is provided with a through hole. The other end of the tie rod 31 is movably inserted through the through hole and extends to the outside of the support plate 3. A pressing member is installed at the other end of the tie rod 31. The pressing member presses against the side of the support plate 3 away from the locking plate 1.

[0056] After the anchor jaw 62 is inserted between the plurality of wedge-shaped clamping blocks 11 at the port of the first through hole a, push the support plate towards the locking plate to make the extrusion ring radially extrude the plurality of wedge-shaped clamping blocks. After the plurality of wedge-shaped clamping blocks clamp the anchor jaw, install a pressing member at the other end of the tie rod so that the pressing member presses against the side of the support plate away from the locking plate. At this time, the end face of the push sleeve abuts against the end face of the anchor jaw.

[0057] In this embodiment, refer to Figure 10 and Figure 11 , the push sleeve 32 is coaxially arranged with the anchor jaw 62. The outer diameter of the push sleeve 32 is adapted to the outer diameter size of the end of the anchor jaw 62.

[0058] Refer to Figure 4 , a plurality of elastic cushion blocks 33 that press against the end of the anchor jaw 62 are connected to the end face of the push sleeve 32. The plurality of elastic cushion blocks 33 are arranged at intervals along the circumferential direction of the push sleeve 32. On the one hand, the elastic cushion blocks have anti-slip properties, and on the other hand, they can play a buffering effect to prevent the end of the anchor jaw from being damaged when knocking the push sleeve.

[0059] Refer to Figure 7 As shown in , the auxiliary construction device for the anchor jaw of the prestressed beam of the present invention includes a receiving box 4. The receiving box 4 is formed with a first accommodating groove and a plurality of second accommodating grooves. The support plate 3 is detachably embedded in the first accommodating groove, and a receiving plate 41 is detachably embedded in the second accommodating groove. The receiving plate 41 is vertically provided with a plurality of limiting columns 42 for the anchor jaw 62 to be sleeved. The positions of the plurality of limiting columns 42 correspond to the positions of the plurality of first through holes a on the locking plate 1 one by one.

[0060] Before inserting the anchor clip into the space between multiple wedge-shaped clamping blocks, the support plate is placed in the first accommodation groove. And a storage plate is placed in the second accommodation groove. When it is necessary to insert the anchor clip into the limiting sleeve, the storage plate is taken out, and the whole plate of anchor clips is inserted into the limiting sleeve in multiple first through holes of the locking plate at one time, so that multiple anchor clips are loaded into multiple wedge-shaped clamping blocks at one time, improving the installation efficiency of the prestressed bridge.

[0061] The present invention provides a construction method for an auxiliary construction device for anchor clips of a prestressed beam, including the following steps:

[0062] S1: One end parts of multiple anchor clips 62 are respectively inserted between multiple wedge-shaped clamping blocks 11 at the ports of multiple first through holes a of the locking plate 1.

[0063] In this embodiment, the storage plate is connected to the wall of the second accommodation groove by threads. When inserting multiple anchor clips into multiple limiting sleeves on the locking plate, the storage plate is rotated to remove the whole plate of anchor clips and load them into multiple wedge-shaped clamping blocks at one time.

[0064] S2: The tie rod 31 is tied between the locking plate 1 and the support plate 3 to make the push rod 21 push against the extrusion ring 2. The extrusion ring 2 closes multiple wedge-shaped clamping blocks 11 to clamp the anchor clip 62, and the top push sleeve 32 abuts against the end of the anchor clip 62.

[0065] Push the support plate towards the locking plate, so that the extrusion ring radially squeezes multiple wedge-shaped clamping blocks to clamp the anchor clip

[0066] S3: The support plate 3 is hoisted to the anchor plate 6 on the bridge 5, so that the other end parts of multiple anchor clips 62 are respectively aligned with the prestressed cables 63 in multiple accommodation holes of the anchor plate 6.

[0067] S4: Push the support plate 3, so that the other end parts of multiple anchor clips 62 are inserted into multiple accommodation holes of the anchor plate 6 at one time, and the anchor clip is sleeved on the prestressed cable.

[0068] The anchor plate 6 of the bridge is installed on the anchor backing plate 61. After the anchor clip is inserted into the accommodation hole of the anchor plate, the prestressed cable in the anchor plate passes through each anchor clip. The end of the prestressed cable passes through the top push sleeve and extends to the outside of the top push sleeve.

[0069] S5: Knock the top push sleeve towards the bottom of the accommodation hole, so that the outer side wall of the anchor clip 62 closely fits the inner side wall of the accommodation hole.

[0070] Use a rubber hammer to knock the top push sleeve, so that the top push sleeve tightly presses the anchor clip, and further makes the outer side wall of the anchor clip 62 closely fit the inner side wall of the accommodation hole.

[0071] S6: Remove the tie rod 31 and pull the support plate 3 in the opposite direction along the direction of striking the push sleeve, so that the extrusion ring 2 opens the multiple wedge-shaped clamping blocks 11 to release the anchor clamping piece 62 with the multiple wedge-shaped clamping blocks 11.

[0072] After the outer wall of the anchor clamp is tightly attached to the inner wall of the receiving hole, the pressing member (i.e., nut) is removed so that the support plate can move along the tie rod back to the locking plate, thereby causing the extrusion ring to move toward the first end of the wedge-shaped clamp. After the extrusion ring moves to the top of the arc surface of the wedge-shaped clamp, it continues to be pulled to the support plate, and the extrusion ring presses against the first end of the wedge-shaped clamp, causing the wedge-shaped clamp to flip toward the outside of the limiting sleeve, thereby causing multiple wedge-shaped clamps to detach from the anchor clamp.

[0073] The anchor clip auxiliary construction device and construction method of the prestressed beam of the present invention adopts multiple extrusion rings to synchronously radially extrude wedge-shaped clamping blocks to lock multiple anchor clips, so that multiple anchor clips can be installed synchronously, which not only saves manpower but also ensures the uniformity of the clip positions, improves the installation efficiency of the anchor clips and reduces the rework rate, thus providing a guarantee for subsequent construction. At the same time, it is convenient to fix multiple anchor clips and put them on the prestressed cable (i.e., steel strand). When the clamping device fixes the clip, the end face of the push sleeve is pressed against the end face of the anchor clip, which cushions and reduces shock for the hammering of the construction personnel when the anchor clip is tightened, and makes each clip evenly stressed, thus preventing the construction personnel from using too much force and damaging the clip.

[0074] The anchor clip auxiliary construction device for prestressed beams of the present invention is easy to disassemble and can be quickly removed after use without affecting subsequent construction. It is suitable for the installation of anchor clips for construction of various types of prestressed beams, has strong practicality, is easy to operate, and is convenient to carry.

[0075] The anchor clip auxiliary construction device for the prestressed beam of the present invention is provided with a storage box, and the support plate is connected to a handle 34, which is convenient for carrying and collecting anchor clips and lifting the support plate. When in use, the whole set or the whole plate of anchor clips can be directly taken out for installation, thereby improving the preparation efficiency of the anchor clips and the protection of the anchor clips.

[0076] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
