Abstract
Description
Technical Field
[0001] The present invention relates to the field of bridge engineering construction; specifically, the present invention relates to a deep-buried anchor sleeve fixing device for a large cantilever inverted T-shaped cap beam. Background Art
[0002] With the continuous advancement of highway transportation network construction, the construction of large bridges is increasing. The large cantilever inverted T-shaped cap beam is a structural form commonly used in bridge engineering. The construction of prestressing is of utmost importance, and its construction quality directly affects the safety and service life of the bridge. The accurate positioning of the deep-buried anchor sleeve of the inverted T-shaped cap beam is a necessary condition to ensure the quality of prestressing construction and is an indispensable process in construction.
[0003] Under normal conditions, the deep-buried anchor sleeve of the inverted T-shaped cap beam is connected with the sleeve pad and the anchor pad and then spot-welded to the main steel bar. However, during the concrete pouring process, the impact pressure of the concrete causes the main steel bar to deform and shake, increasing the probability of the position of the deep-buried anchor sleeve to shift, resulting in a large deviation in the accuracy of the prestressed construction. The inverted T-shaped cap beam of this project adopts the post-tensioning method at both ends. The cantilever length at both ends is 7m. 16 prestressed tendons are set at each end, which are tensioned in 2 stages, with 8 tendons in each stage. Under the conventional construction method, the quality of prestressed construction is not easy to control, which is easy to increase the construction cost of rework and maintenance. When the existing anchor sleeve and template are spliced, the anchor sleeve is usually hoisted by a crane and then the direction, position and angle of the anchor sleeve are manually adjusted to match the positioning hole and bolt hole on the template. The operation process is complicated and difficult. The multiple manual adjustments have greatly affected the construction progress. Summary of the invention

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figures 1 to 7 As shown, a typical embodiment of the present invention provides a deep-buried anchor sleeve fixing device for a large cantilever inverted T-shaped cap beam, comprising a base 1, a slide 2, a support frame 3 and a template clamp 4. The base 1 is "L"-shaped, and the slide 2 is slidably installed on the base 1 in the transverse direction. A first screw-type lifting structure 5 is installed on one side of the slide 2. The support frame 3 can be slidably installed on the first screw-type lifting structure 5 forward and backward. The support frame 3 is used to place the anchor sleeve 6, and the template clamp 4 is installed on the left and right sides of the base 1.
[0027] In this embodiment, the template is clamped on the base 1 by the template clamp 4, and the slide 2 is slidably installed between the template and the base 1. The slide 2 can slide left and right on the base 1. The position of the support frame 3 can be adjusted in the height direction by rotating the first screw 4-4 support structure. After the template is fixed on the base 1 by the template clamp 4, the position of the support frame 3 can be adjusted in the height direction according to the position of the positioning hole of the anchor sleeve 6 on the template, and then the anchor sleeve 6 is placed on the support frame 3, and the slide 2 is moved left and right to adjust the support frame 3 in the lateral direction to the position of the anchor sleeve on the template. When the center of the cylinder 6 is aligned, the anchor sleeve 6 is rotated in the circumferential direction to rotate the bolts on both sides of the anchor sleeve 6 to the bolt holes on the corresponding template, and the anchor sleeve 6 can be pushed into the template and spliced with the template. After the first splicing is completed, there is no need to adjust the position of the support frame 3 in the height direction during the subsequent alignment of the anchor sleeve 6 in the same row. It is only necessary to move the slide seat 2 left and right to adjust the position of the support frame 3 so that it can be aligned with the anchor sleeve 6 positioning holes in the same row on the template. The entire construction process is stable and controllable, with high precision and convenient operation, which reduces the difficulty of construction.
[0028] The template fixture 4 includes a fixing plate 4-1, a mounting plate 4-2, a pressing plate 4-3 and a first screw 4-4. The fixing plate 4-1 is arranged on one side of the template, the mounting plate 4-2 is arranged on the other side of the template, the pressing plate 4-3 is located between the fixing plate 4-1 and the mounting plate 4-2, and one end of the first screw 4-4 is fixedly connected to the pressing plate 4-3, and the other end passes through the mounting plate 4-2.
[0029] In this embodiment, the template is located on the side of the fixed plate 4-1 facing the mounting plate 4-2, and a threaded hole is opened on the mounting plate 4-2. The first screw 4-4 is matched with the threaded hole on the mounting plate 4-2. The template is inserted into the base 1 from left to right until it is close to one side of the vertical section of the base 1. Then, the pressure plate 4-3 is pressed against the template by rotating the first screw 4-4, and the template is stably clamped between the fixed plate 4-1 and the pressure plate 4-3. By arranging a template clamp 4 on the left and right, the template can be stably clamped on the base 1.
[0030] The support frame 3 includes a slide 3-1, a first U-shaped plate 3-2, a second U-shaped plate 3-3 and an openable and closable buckle 3-4. The slide 3-1 is slidably installed on the first screw-type lifting structure 5 in the transverse direction. The first U-shaped plate 3-2 is slidably installed on the slide 3-1 in the front-to-back direction and is used to place the anchor sleeve 6. The bottom end of the first U-shaped plate 3-2 is fixedly connected with a connecting plate 3-5. The second U-shaped plate 3-3 is fixedly arranged at one end of the connecting plate 3-5 away from the first U-shaped plate 3-2. The openable and closable buckle 3-4 is installed on the top of the second U-shaped plate 3-3.
[0031] In this embodiment, the outer surface of the large cylinder at the front end of the anchor sleeve 6 is supported by the first U-shaped plate 3-2, and the second U-shaped plate 3-3 is located at the bottom of the outer surface of the small cylinder at the rear end of the anchor sleeve 6 to support the anchor sleeve 6. One side surface of the first U-shaped plate 3-2 contacts the end surface of the anchor sleeve 6 and the bolt connection. Since the area of the anchor sleeve 6 outside the first U-shaped plate 3-2 and the second U-shaped plate 3-3 is larger than the area inside the first U-shaped plate 3-2 and the second U-shaped plate 3-3, an openable and closable buckle ring 3-4 is rotatably installed above the second U-shaped plate 3-3. When the anchor sleeve 6 is placed on the support frame 3, the anchor sleeve 6 can be stably clamped on the support frame 3 by closing the buckle ring. At the same time, the anchor sleeve 6 can be rotated on the support frame 3 to adjust the bolts on both sides of the anchor sleeve 6 and the bolt holes on the template. The anchor sleeve 6 and the template are spliced by sliding the first U-shaped plate 3-2 forward to insert the anchor sleeve 6 into the positioning hole of the template anchor sleeve 6.
[0032] A positioning assembly 7 is provided on the side of the slide 2 away from the support frame 3. The positioning assembly 7 includes a second screw-type lifting structure 7-1, a fixed seat 7-2, an outer sleeve 7-3, an inner sleeve 7-4 and a force storage spring 7-5. The second screw-type lifting structure 7-1 is installed on the top of the slide 2 away from the support frame 3. There are two fixed seats 7-2, which are fixedly installed on the second screw 7-11 type lifting structure in an upper and lower distribution. The outer sleeve is slidably installed on the fixed seat 7-2. A telescopic rod 7-6 is provided between the outer sleeve and the fixed seat 7-2. The inner sleeve 7-4 is slidably connected to the outer sleeve, and the force storage spring 7-5 is provided between the inner sleeve and the outer sleeve.
[0033] In this embodiment, the positioning assembly 7 is located on the opposite side of the anchor sleeve 6. In the height direction, the positioning assembly 7 and the slide 2 can be adjusted to the same height through the first bolt-type lifting structure and the second screw 7-11-type lifting structure, which is convenient for the subsequent alignment of the anchor sleeve 6. The fixed seat 7-2 is used to fix the positioning assembly 7. The positioning assembly 7 is a retractable positioning assembly 7. In the process of adjusting the anchor sleeve 6 through the bolt hole in the lateral direction of the slide 2, the inner sleeve 7-4 of the positioning assembly 7 provides an initial elastic force for the inner sleeve 7-4 in the force storage spring 7-5, so that the inner sleeve 7-4 can be inserted into the bolt hole when the positioning assembly 7 passes through the bolt hole, thereby completing the lateral positioning of the slide 2 and aligning the anchor sleeve 6 and the anchor sleeve 6 positioning holes.
[0034] A rotating assembly 8 is provided at one end of the slide 3-1 away from the first U-shaped plate 3-2. The rotating assembly 8 includes a driving rod 8-1, a swivel 8-2 and a baffle 8-3. The swivel 8-2 is installed at the end of the slide 3-1 away from the first U-shaped plate 3-2. A circle of teeth is provided on the outer surface of the swivel 8-2. The driving rod 8-1 is located below the slide 3-1. A gear 8-7 is provided at one end of the driving rod 8-1, and the other end of the driving rod 8-1 passes through the connecting plate 3-5. The gear 8-7 is adapted to the teeth on the outer surface of the swivel 8-2. There are two baffles 8-3, which are respectively provided at both ends of the swivel 8-2.
[0035] In this embodiment, after the positioning assembly 7 is inserted into the bolt hole to position the anchor sleeve 6 laterally, the swivel 8-2 on the rotating assembly 8 is consistent with the center of the anchor sleeve 6 positioning hole on the template, and the swivel 8-2 can be driven to rotate by rotating the driving rod 8-1. The rotation of the swivel 8-2 causes the baffle 8-3 to contact the bolts on both sides of the anchor sleeve 6, and pushes the bolts on both sides of the anchor sleeve 6 to rotate the anchor sleeve 6 to adjust the position of the bolts on both sides of the anchor sleeve 6. Since the inner sleeve 7-4 of the positioning assembly 7 is in an extended state, the inner sleeve 7-4 extends toward one end of the template to be within the range of the baffle 8-3, and the baffle 8-3 drives the anchor sleeve 6 to rotate until it contacts the inner sleeve 7-4, so that the baffle 8-3 is limited by the inner sleeve 7-4, so that the bolts at one end of the baffle 8-3 away from the inner sleeve are located on the same horizontal plane as the inner sleeve 7-4, so that the bolts on both sides of the anchor sleeve 6 and the bolt holes on the template are aligned.
[0036] A spiral groove and a straight groove are provided on the outer surface of the driving rod 8-1, and a driving sleeve 8-8 is sleeved on the outer surface of the driving rod 8-1. The driving sleeve 8-8 is slidably sleeved in the connecting plate 3-5, and an extension rod 8-9 is provided on the inner wall surface of the driving sleeve 8-8. The extension rod 8-9 is adapted to the spiral groove and the straight groove, and a handle 8-10 is provided on the top of one end of the driving sleeve 8-8 away from the connecting plate 3-5.
[0037] In this embodiment, the driving sleeve 8-8 can slide back and forth in the connecting plate 3-5, and the spiral groove is connected to the straight groove, and the straight groove is located on the side of the spiral groove facing the template. When the driving sleeve 8-8 slides forward, since the extension rod 8-9 is located in the spiral groove on the driving rod 8-1, when the extension rod 8-9 is driven by the driving sleeve 8-8 to move forward, the driving rod 8-1 is driven to rotate to the left through the spiral groove. The driving rod 8-1 rotates to the left through the gear 8-7 to make the swivel 8-2 rotate to the right. When the swivel 8-2 rotates to the right until the baffle 8-3 contacts the inner sleeve 7-4, the extension rod 8-9 contacts the straight groove. At this time, the driving rod 8-1 no longer rotates, so that the baffle 8-3 no longer rotates, and the bolts on both sides of the anchor sleeve 6 will not rotate to the left.
[0038] One end of the two baffles 8-3 is fixedly connected to the swivel 8-2, and the other end extends to the top or bottom of the anchor sleeve 6. An extension plate 8-4 is provided at the outward end of the upper baffle 8-3, and the extension plate 8-4 is rotatably connected to a rotating rod 8-5, and a rotating plate 8-6 is provided on the top of the rotating rod 8-5.
[0039] When the swivel 8-2 is turned to the right, the baffle 8-3 on the left side rotates to the right to contact the bolt, so that the anchor sleeve 6 rotates. The rotating rod 8-5 is located within the range of the inner rotating rod, so when the rotating rod 8-5 does not contact the inner sleeve 7-4, the bottom of the rotating rod 8-5 is facing downward. When the baffle 8-3 pushes the anchor sleeve 6 to contact the inner sleeve 7-4, the rotating rod 8-5 contacts the inner sleeve 7-4 first, and the baffle 8-3 continues to turn right, so that the rotating rod 8-5 is squeezed by the inner sleeve 7-4, and the bottom of the rotating rod 8-5 flips upward, and the rotating plate 8-6 on the top of the rotating rod 8-5 flips downward, so that one side of the rotating plate 8-6 contacts the bolt on one side of the anchor sleeve 6, so that the anchor sleeve 6 will not rotate to the right, and the baffle 8-3 will cooperate to stably fix the anchor sleeve 6 in a state where the bolt holes are aligned with the holes.
[0040] A piston 7-7 is slidably arranged on the inner wall surface of the outer sleeve 7-3 on the side away from the template, a spring seat 7-8 is arranged on the end of the piston 7-7 away from the template, a force storage spring 7-5 is arranged between the spring seat 7-8 and the piston 7-7, the inner sleeve 7-4 is arranged on the side of the piston 7-7 facing the template, an air hole 7-9 is arranged at the bottom of the end of the outer sleeve 7-3 facing the template, and an insertion rod 7-10 is slidably sleeved inside the inner sleeve 7-4, and the outer surface of the end of the insertion rod 7-10 facing the piston 7-7 is fitted with the inner wall of the inner sleeve 7-4.
[0041] In this embodiment, when the transverse sliding seat 2 adjusts the anchor sleeve 6 to align with the positioning hole of the anchor sleeve 6 laterally, the insertion rod 7-10 is located inside the inner sleeve 7-4, and the inner sleeve 7-4 is located inside the outer sleeve 7-3. One end of the insertion rod 7-10 is pressed by the template, so that the air inside the insertion rod 7-10 is compressed into the piston 7-7 cavity between the end of the inner sleeve 7-4 and the piston 7-7. The piston 7-7 is squeezed by the compressed air, so that the storage spring 7-5 is compressed. When the positioning assembly 7 remains in a compressed state and passes through the bolt hole on the template, the insertion rod 7-10 loses the extrusion of the template, so that the storage spring 7-5 is released, and the piston 7-7 is pushed by the storage spring 7-5, so that the compressed air pushes the insertion rod 7-10 to extend to the longest state and then drives the inner sleeve 7-4 to extend. When the inner sleeve 7-4 is extended to the longest state, the air hole 7-9 is opened, so that the compressed gas is released, and the inner sleeve 7-4 and the plug rod 7-10 both pass through the bolt hole and maintain the longest state. By utilizing air pressure, the component is extended longer, which is convenient for the baffle 8-3 to contact the inner sleeve 7-4; when the anchor sleeve 6 is aligned with the bolt hole, the anchor sleeve 6 is pushed to move forward, so that the bolts on both sides of the anchor sleeve 6 push the plug rod 7-10 to reset. When the plug rod 7-10 is reset, the air hole 7-9 is closed, and the plug rod 7-10 moves in the opposite direction to the inside of the inner sleeve 7-4 to drive the inner sleeve 7-4 to reset, so that the air between the inner sleeve 7-4 and the outer sleeve 7-3 is compressed, and the outer sleeve 7-3 is pressurized, so that when the slide seat 2 is moved horizontally next time, the gas inside the outer sleeve 7-3 remains compressed to squeeze the storage spring 7-5, so that it can be smoothly pushed out when the bolt hole is aligned next time.
[0042] One end of the spring seat 7-8 away from the piston 7-7 is fixedly connected to the second screw 7-11, and the other end of the second screw 7-11 extends outward and passes through the end of the outer sleeve 7-3. A nut 7-12 is provided on the side of the second screw 7-11 outside the range of the outer sleeve 7-3, and the nut 7-12 is adapted to the second screw 7-11.
[0043] In this embodiment, the pressing force of the nut 7-12 on the outer sleeve 7-3 is removed by flipping the nut 7-12, and then the second screw 7-11 is rotated to move the spring seat 7-8 outward. By removing the pressure of the storage spring 7-5, the internal air pressure of the outer sleeve 7-3 is removed, so that the inner sleeve 7-4 and the insertion rod 7-10 can be stored in the outer sleeve 7-3 when not in use.
[0044] A ball 7-13 is provided at the end of the insertion rod 7-10 facing the template, and a fixing sleeve 9 is connected to the end of the fixing seat 7-2 away from the template. The fixing sleeve 9 is sleeved on the outer surface of the outer sleeve 7-3. A sliding groove 11 is opened on the fixing seat 7-2, and a sliding plate 10 is slidably arranged in the sliding groove 11. One telescopic end is connected to the fixing sleeve 9 and the other end is connected to the sliding plate 10. The end of the sliding plate 10 away from the sliding groove 11 is fixedly connected to the outer sleeve 7-3.
[0045] In this embodiment, the ball 7-13 at the end of the rod 7-10 can make the ball 7-13 at the end of the rod 7-10 contact the template when the transverse sliding seat 2 is aligned with the anchor sleeve 6, thereby reducing the friction between the rod 7-10 and the template, making it easier to transverse the sliding seat 2 and reducing the impact of friction on the inner sleeve 7-4 and the rod 7-10 when inserting the hole.
[0046] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
