Description

Technical Field

[0001] This invention mainly relates to the technical field of prefabricated buildings, specifically a slipform construction method for rectangular slender frame columns with prefabricated tie beams. Background Technology

[0002] Slip-form construction of precast tie beam rectangular slender frame columns is an advanced building construction technique mainly used in the field of prefabricated buildings. This construction method uses slipform as the main formwork system, which is hydraulically or mechanically driven to stagger the formwork from bottom to top in the vertical direction, thereby achieving continuous production.

[0003] The prior art describes a construction method for slipform and operating platform of ultra-high rectangular columns, which includes steps such as rectangular column construction, slipform installation, operating platform installation, jack installation, guide sleeve installation, anti-deviation device installation, overall slipforming, and slipform and operating platform dismantling.

[0004] The above-mentioned technology can effectively realize the slip-lift construction of rectangular columns, greatly reducing the erection of operating scaffolds and high-altitude operations. The operation is controllable, reducing construction costs and increasing construction efficiency. However, when the formwork is raised, friction will cause the formwork to lift some of the concrete in contact, causing certain damage and leaving irregular marks on the surface of the concrete block. It is necessary to use suspended scaffolds to allow workers to repair the exposed surface, thereby increasing the labor intensity of the workers. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a slipform construction method for rectangular slender frame columns with precast tie beams, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A slipform construction method for rectangular slender frame columns with precast tie beams includes the following steps: S1. Installation of slender frame columns: transport the prefabricated frame columns to the construction site and connect them with the pre-embedded steel plates and reinforcing bars. S2. Slipform assembly: Install the three-dimensional frame, lifting rod, lifting baffle, template operating platform, and through-hole jack in the slipform device around the slender frame column in sequence, and set the interval between the template and the frame column according to the construction requirements. S3. Overall slipforming: The through-type jack is opened and climbs upward along the lifting rod, driving the operating platform to rise. The operating platform drives the formwork to rise through the lifting baffle. After rising to a certain position, the formwork is used to continue the construction and pouring. S4. Repair: After the template slides up, the lifting plate in the bottom receiving groove moves along the sliding groove under the control of the spring telescopic cylinder, and drives the cover plate to move out of the template. Then the first telescopic cylinder works to push the push plate to move, and under the action of the connecting plate, it drives the cover plate to move along the square sliding groove to cover the exposed concrete outer wall. Then, the cement pump in the storage tank operates, spraying concrete from the spray pipe onto the outer wall of the concrete through the pipeline. At this time, the second telescopic cylinder of the leveling component operates, pushing the scraper downward to scrape the concrete. When encountering potholes or uneven areas, the scraped concrete is used to repair and level them. Finally, the remaining concrete falls into the receiving pipe through the opening and is then sent back into the storage tank through the pipeline by the suction pump, completing the repair work.

[0007] Specifically, the bottom of the template is provided with a storage groove, and a repair mechanism is provided in the storage groove. The repair mechanism is used to repair the exposed concrete block surface. The repair mechanism consists of a lifting plate, a cover plate, a scraping component, and a storage box. A long strip of spray pipe is horizontally installed at the top inside the cover plate, and the storage box is fixed to the top of the outer wall of the template. The cover plate is located on the lower surface of the lifting plate and is slidably connected. The scraping component is disposed in the cover plate and is located above the spray pipe.

[0008] Specifically, the storage slot has sliding grooves on both sides of its side walls. Both ends of the lifting plate are located in the sliding grooves. Ball bearings are embedded in both end walls of the lifting plate. Each ball bearing is in contact with the wall of the sliding groove and is slidably connected. The upper surface of the lifting plate is connected to the top wall of the storage slot via two spring telescopic cylinders. Both spring telescopic cylinders are fixedly connected to the top wall of the storage slot via bolts. The telescopic ends of both spring telescopic cylinders are fixed to the lifting plate with bolts.

[0009] Specifically, in this technical solution, square sliding grooves are provided at both ends of the lifting plate, and a groove is provided at the top of the cover plate. Connecting plates are welded to both sides of the top of the cover plate. Push plates are bolted to both connecting plates through the square sliding grooves.

A first telescopic cylinder is provided on the side of the upper surface of the lifting plate located on the push plate. The two first telescopic cylinders are fixedly connected to the lifting plate by bolts.

[0010] Specifically, the template is equipped with an injection pipe inside. One end of the injection pipe is connected to the storage box, and the other end of the injection pipe is located in the receiving groove and connected to a first telescopic pipe. The bottom end of the first telescopic pipe is connected to a horizontal main pipe. The lower surface of the main pipe is connected to several branch pipes, and all of the branch pipes penetrate the outer wall of the cover plate and are connected to the spray pipe.

[0011] Specifically, the leveling component includes a scraper, both ends of which are in contact with and slidably connected to the inner wall of the cover plate. A movable slide groove is provided on one side of the square slide groove on the lifting plate. An installation plate is provided above each of the two movable slide grooves. A second telescopic cylinder is bolted to the upper surface of each of the two installation plates. The telescopic ends of the two second telescopic cylinders pass through the installation plate and the movable slide groove in sequence and are fixedly connected to the scraper. The lower surfaces of the two installation plates are slidably connected to the upper surface of the lifting plate.

[0012] Specifically, the top of one side wall of the cover plate is provided with a storage groove, and a movable block is provided in the storage groove. A cleaning block is fixed to the top of one end of the movable block near the surface of the concrete block. The top wall of the storage groove is flush with the lower surface of the scraper. The scraping surface of the cleaning block is set to be arc-shaped, and the top of the cleaning block is in contact with the top wall of the storage groove. A lead screw is provided above the spray pipe, and a parallel sliding rod is provided on one side of the lead screw. The other end of the movable block is sleeved on the lead screw and the sliding rod.

[0013] Specifically, in this technical solution, a drive motor is bolted to the top of one outer wall of the cover plate. The two ends of the lead screw are rotatably connected to the inner side wall of the cover plate and the wall of the storage slot, respectively. The output end of the drive motor is fixedly connected to the lead screw. The two ends of the slide rod are fixedly connected to the inner side wall of the cover plate and the wall of the storage slot, respectively. The width of the cleaning block is the same as the width of the scraper. A through groove is opened at the bottom of one of the sliding grooves, and the through groove matches the drive motor. A matching sensor and a sensing block are embedded in one side of the top wall of the cover plate and one side of the upper surface of the scraper, respectively. The sensor is connected to the drive motor.

[0014] Specifically, in this technical solution, the inner bottom of the cover plate is set as a receiving pipe, and an opening is opened on the upper surface of the receiving pipe near the surface of the concrete block. A suction pump is installed on the side of the storage box away from the formwork. The suction end of the suction pump is connected to a suction pipe, and the bottom end of the suction pipe is connected to a second telescopic pipe. The bottom end of the second telescopic pipe is connected to a horizontal pipe, and the receiving pipe is connected to the horizontal pipe through several connecting pipes.

[0015] Specifically, in this technical solution, the bottom of the outer wall of the template away from the surface of the concrete block is provided with several U-shaped grooves, several of the U-shaped grooves are connected to the receiving groove, several of the connecting pipes are matched with the U-shaped grooves, and the openings are the same width as the scraper provided in the leveling component.

[0016] In summary, the present invention has the following advantages: when the template is raised, the exposed concrete block surface will be automatically repaired, filling most of the pits and marks, reducing the amount of manual repair work, thereby reducing labor intensity, and at the same time, the remaining concrete after repair can be recycled. First, the prefabricated slender frame columns are installed on the construction site. Then, the slipform device is installed on the frame columns. When the formwork is raised, the spring telescopic cylinder in the bottom receiving groove is activated, pushing the lifting plate to move down along the sliding groove. The moving lifting plate drives the cover plate out of the formwork and stretches the first telescopic tube. Then, the first telescopic cylinder works, pushing the push plate to move, so that the push plate drives the connecting plate to move along the square sliding groove with the cover plate. At this time, the cover plate contacts the surface of the exposed concrete block, and at the same time, the leveling component also contacts the surface of the concrete block as the cover plate moves. Next, the cement pump in the storage tank operates, spraying concrete from the injection pipe, the first telescopic pipe, the main pipe, and multiple branch pipes onto the surface of the concrete block. Then, the first telescopic cylinder of the leveling component operates, pushing the scraper downwards. The scraper pushes the sprayed concrete to move, filling the uneven surface with concrete until the scraper moves to the bottom of the cover plate, located at the opening of the receiving pipe. The remaining concrete is located inside the receiving pipe. At this time, the suction pump operates, generating suction through the suction pipe, the second telescopic pipe, the horizontal pipe, and multiple connecting pipes, sending the remaining concrete back into the storage tank. Finally, the exposed concrete block surface is cured and cleaned by the staff. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described. Example

[0021] Please see Figure 1-8 As shown, a slipform construction method for rectangular slender frame columns with precast tie beams includes the following steps: S1. Installation of slender frame columns: transport the prefabricated frame column 1 to the construction site and connect and install it with the pre-embedded steel plates and reinforcing bars. S2. Slipform assembly: Install the three-dimensional frame, lifting rod, lifting baffle, template 3 operating platform, and through-hole jack in the slipform device 2 around the slender frame column in sequence, and set the interval between the template 3 and the frame column 1 according to the construction requirements. S3. Overall sliding: The through-hole jack is opened and climbs upward along the lifting rod, driving the operating platform to rise. The operating platform drives the formwork 3 to rise through the lifting baffle. After rising to a certain position, the construction and pouring are continued through the formwork 3. S4. Repair: After the template 3 is raised, the lifting plate 5 in the bottom receiving groove 301 moves along the sliding groove 302 under the control of the spring telescopic cylinder 502, and drives the cover plate 6 to move out of the template 3. Then the first telescopic cylinder 6051 works to push the push plate 605 to move. Under the action of the connecting plate 604, the cover plate 6 moves along the square sliding groove 503 to cover the exposed concrete outer wall. Then, the cement pump in the storage tank 8 operates to spray concrete from the spray pipe 602 onto the outer wall of the concrete through the pipeline. At this time, the second telescopic cylinder 703 of the leveling component 7 operates, pushing the scraper 701 down to scrape the concrete. When encountering potholes, the scraped concrete is used to repair and level them. Finally, the remaining concrete falls into the receiving pipe 603 through the opening 6031, and is sent back into the storage tank 8 through the pipeline under the action of the suction pump 801, completing the repair work.

[0022] The template 3 of this application is also equipped with a main control board and a top power supply line. Power is supplied through the power supply line, and the main control board is wirelessly connected to an external controller to achieve remote control. This application is applicable to tall and slender rectangular columns. The sliding mold device 2 adopts existing technology, which is not described in detail in the text.

[0023] Please see Figure 2-6 As shown, the bottom of the template 3 is provided with a storage groove 301, and a repair mechanism 4 is provided in the storage groove 301. The repair mechanism 4 is used to repair the exposed concrete block surface. The repair mechanism 4 consists of a lifting plate 5, a cover plate 6, a scraping assembly 7, and a storage box 8. A long strip-shaped spray pipe 602 is horizontally installed at the top inside the cover plate 6. The storage box 8 is fixed to the top of the outer wall of the template 3. Sliding grooves 302 are provided on both sides of the receiving groove 301. Both ends of the lifting plate 5 are located in the sliding grooves 302. Ball bearings 501 are embedded in both end walls of the lifting plate 5. Each ball bearing 501 contacts and slides against the groove wall of the sliding groove 302. The upper surface of the lifting plate 5 is connected to the top wall of the receiving groove 301 via two spring telescopic cylinders 502. Both spring telescopic cylinders 502 are bolted to the receiving groove. The top wall of the trough 301 is fixedly connected. The telescopic ends of the two spring telescopic cylinders 502 are bolted to the lifting plate 5. The lifting plate 5 has square sliding grooves 503 at both ends. The top of the cover plate 6 has a groove 601. The top two sides of the cover plate 6 are welded with connecting plates 604. The two connecting plates 604 are bolted through the square sliding grooves 503 and have push plates 605 installed on them. The lower surfaces of the two push plates 605 are slidably connected to the upper surface of the lifting plate 5. The upper surface of the lifting plate 5 is provided with a first telescopic cylinder 6051 on the side of the push plate 605. The two first telescopic cylinders 6051 are fixedly connected to the lifting plate 5 by bolts. The cover plate 6 is located on the lower surface of the lifting plate 5 and is slidably connected. The leveling component 7 is disposed in the cover plate 6 and is located above the spray pipe 602. The template 3 is provided with an injection pipe 303 inside. One end of the injection pipe 303 is connected to the storage box 8, and the other end of the injection pipe 303 is located in the receiving groove 301 and connected to a first telescopic pipe 3031. The bottom end of the first telescopic pipe 3031 is connected to a horizontal main pipe 304. The lower surface of the main pipe 304 is connected to several branch pipes 3041. Several branch pipes 3041 penetrate the outer wall of the cover plate 6 and are connected to the spray pipe 602. A cement pump is installed in the storage box 8 and its output port is connected to the injection pipe 303. The inner bottom of the cover plate 6 is provided with a receiving pipe 603. An opening 6031 is opened on the upper surface of the receiving pipe 603 near the surface of the concrete block. A suction pump 801 is installed on the side of the storage box 8 away from the template 3. The suction end of the suction pump 801 is connected to a suction pipe 802. The bottom end of the suction pipe 802 is connected to a second telescopic pipe 8021. The bottom end of the second telescopic pipe 8021 is connected to a horizontal pipe 803. The receiving pipe 603 is connected to the horizontal pipe 803 through several connecting pipes 804. Several U-shaped grooves 305 are opened on the bottom of the outer wall of the template 3 away from the surface of the concrete block. Several U-shaped grooves 305 are connected to the receiving groove 301. Several connecting pipes 804 are matched with the U-shaped grooves 305. The opening 6031 has the same width as the scraper 701 provided in the leveling component 7.

[0024] During the slipform construction of the precast rectangular slender frame column 1, the workers first install the precast slender frame column 1 on the construction site, and then install the slipform device 2 on the frame column 1 for pouring. When the formwork 3 stops sliding, the workers send a signal to the main control board through the controller. After receiving the signal, the main control board starts the spring telescopic cylinder 502. The telescopic ends of the two spring telescopic cylinders 502 push the lifting plate 5 to move. Both ends of the moving lifting plate 5 move along the sliding groove 302 through the ball bearings 501. At the same time, the lifting plate 5 also drives the sliding cover plate 6 to move and move the first telescopic pipe 3. 031 is stretched, causing the cover plate 6 to move out of the receiving groove 301 and stretching the second telescopic tube 8021. At the same time, it drives several connecting tubes 804 to move out of the U-shaped groove 305. At this time, the two first telescopic cylinders 6051 work, and their telescopic ends push the push plate 605 to move. The push plate 605 moves along the square slide groove 503 through the connecting plate 604. The moving connecting plate 604 carries the cover plate 6 to move, so that the cover plate 6 contacts the exposed concrete block surface. When the cover plate 6 moves, it also drives the scraping component 7 to move. The actuator of the scraping component 7 also contacts the exposed concrete block surface. Next, the cement pump works to send the concrete in the storage tank 8 into the injection pipe 303, which then enters the main pipe 304 through the first telescopic pipe 3031 and several branch pipes 3041. The concrete is then evenly sprayed onto the exposed concrete block surface from the spray pipe 602. At this time, the leveling component 7 works to push the concrete to move. When it passes over the pits and bumps on the surface of the concrete block, it is filled until the actuator of the leveling component 7 moves to the opening 6031 of the receiving pipe 603. The remaining concrete is located in the receiving pipe 603. At this time, the suction pump 801 works, which forms a suction force in the receiving pipe 603 through the suction pipe 802, the second telescopic pipe 8021, the horizontal pipe 803, and several connecting pipes 804, sending the remaining concrete back into the storage tank 8. After the repair is completed, the telescopic ends of the two first telescopic cylinders 6051 are retracted. The cover plate 6 is reset through the push plate 605 and the connecting plate 604 until the template 3 slides up again, and the above repair work is repeated. Therefore, when the template 3 rises, this application will automatically repair the exposed concrete block surface, fill most of the pits and marks, reduce the amount of manual repair work, thereby reducing labor intensity, and at the same time, enable the recycling of the remaining concrete after repair.

[0025] Please see Figure 5-8 As shown, the leveling assembly 7 includes a scraper 701, both ends of which are in contact with and slidably connected to the inner wall of the cover plate 6. A movable slide groove 504 is provided on one side of the square slide groove 503 on the lifting plate 5. An mounting plate 702 is provided above each of the two movable slide grooves 504. A second telescopic cylinder 703 is bolted to the upper surface of each of the two mounting plates 702. The telescopic ends of the two second telescopic cylinders 703 pass through the mounting plate 702 and the movable slide groove 504 in sequence and are fixedly connected to the scraper 701. The lower surfaces of the two mounting plates 702 are slidably connected to the upper surface of the lifting plate 5. The sliding mechanism between the rear ends of the scraper 701 and the inner wall is a slide rail. A storage groove 606 is provided on the top of one side wall of the cover plate 6. A movable block 708 is provided in the storage groove 606. A cleaning block 7081 is fixed to the top of the movable block 708 near the surface of the concrete block. The top wall of the storage groove 606 is flush with the lower surface of the scraper 701. The scraping surface of the cleaning block 7081 is arc-shaped, and the top of the cleaning block 7081 is in contact with the top wall of the storage groove 606. A lead screw 706 is provided above the spray pipe 602. A parallel sliding rod 707 is provided on one side of the lead screw 706. The other end of the movable block 708 is sleeved on the lead screw 706 and the sliding rod 707. A drive motor 705 is bolted to the top of one side outer wall of the cover plate 6. The two ends of the lead screw 706 are respectively connected to the cover plate 6. The inner wall of plate 6 and the wall of storage slot 606 are rotatably connected. The output end of drive motor 705 is fixedly connected to lead screw 706. The two ends of slide rod 707 are fixedly connected to the inner wall of cover plate 6 and the wall of storage slot 606 respectively. The width of cleaning block 7081 is the same as the width of scraper 701. A through slot 3021 is opened at the bottom of sliding slot 302. The through slot 3021 matches drive motor 705. A sensor 704 and a sensor block 709 are embedded in one side of the top wall of cover plate 6 and one side of the upper surface of scraper 701 respectively. The sensor 704 is connected to drive motor 705. When cover plate 6 moves out of storage slot 301, drive motor 705 will also move out through through slot 3021.

[0026] When the cover plate 6 moves, the scraper 701 can be pushed to move synchronously via the slide rail. The scraper 701 drives the mounting plate 702 to move on the lifting plate 5 via the telescopic end of the second telescopic cylinder 703 along the moving slide 504. When it is necessary to scrape away the concrete, the two second telescopic cylinders 703 work, and their telescopic ends push the scraper 701 downward. The downward-moving scraper 701 pushes the concrete along the surface of the concrete block, and fills the pits and bumps on the surface of the concrete block until the scraper 701 is located at the opening 6031 of the receiving pipe 603 to collect the remaining concrete. Then the scraper 701... 1. After the upward reset, the sensing block 709 contacts the sensor 704. The sensor 704 sends an electrical signal to the main control board, which then starts the drive motor 705. The output of the drive motor 705 drives the lead screw 706 to rotate, causing the moving block 708 to move laterally under the constraint of the slide rod 707, following the rotation of the lead screw 706. The moving block 708 drives the cleaning block 7081, which cleans the lower surface of the scraper 701, removing the adhering concrete and allowing it to fall along the arc into the receiving pipe 603 below. This ensures the cleanliness of the scraper 701 and guarantees the effectiveness of subsequent scraping.

[0027] The working principle of this invention is as follows: During the slipform construction of the precast rectangular slender frame column 1, the workers first install the precast slender frame column 1 on the construction site, and then install the slipform device 2 on the frame column 1 for pouring. When the formwork 3 stops sliding, the workers send a signal to the main control board through the controller. After receiving the signal, the main control board starts the spring telescopic cylinder 502. The telescopic ends of the two spring telescopic cylinders 502 push the lifting plate 5 to move. Both ends of the moving lifting plate 5 move along the sliding groove 302 through the ball bearings 501. At the same time, the lifting plate 5 also drives the sliding cover plate 6 to move and stretch the first telescopic tube 3031, so that the cover plate 6 moves out of the receiving groove 301 and stretches the first telescopic tube 3031. The two telescopic tubes 8021 are stretched, which simultaneously drives several connecting tubes 804 to move out of the U-shaped groove 305. When the cover plate 6 moves, the scraper 701 can be pushed to move synchronously through the slide rail. The scraper 701 drives the mounting plate 702 to move on the lifting plate 5 through the telescopic end of the second telescopic cylinder 703 along the moving slide groove 504. At this time, the two first telescopic cylinders 6051 work, and their telescopic ends push the push plate 605 to move. The push plate 605 moves along the square slide groove 503 through the connecting plate 604. The moving connecting plate 604 carries the cover plate 6 to move, so that the cover plate 6 contacts the exposed concrete block surface. The scraper 701 will also contact the exposed concrete block surface. Next, the cement pump operates, delivering concrete from the storage tank 8 into the injection pipe 303. The concrete then flows along the first telescopic pipe 3031 into the main pipe 304, and into several branch pipes 3041, where it is evenly sprayed from the spray pipe 602 onto the exposed concrete block surface. At this time, the two second telescopic cylinders 703 operate, their telescopic ends pushing the scraper 701 downwards. The downward-moving scraper 701 pushes the concrete along the concrete block surface, filling in any uneven areas until the scraper 701 is positioned at the opening 6031 of the receiving pipe 603, where any remaining concrete is collected. Then, the scraper 701... After the upward reset, the sensing block 709 contacts the sensor 704, and the sensor 704 sends an electrical signal to the main control board. The main control board then starts the drive motor 705, whose output drives the lead screw 706 to rotate. This causes the moving block 708 to move laterally under the constraint of the slide rod 707, following the rotation of the lead screw 706. The moving block 708 drives the cleaning block 7081, which cleans the lower surface of the scraper 701, removing the adhering concrete. The scraper then falls along the arc surface into the receiving pipe 603 below, thus ensuring the cleanliness of the scraper 701 and guaranteeing the subsequent scraping effect. At this time, the suction pump 801 works, and through the suction pipe 802, the second telescopic pipe 8021, the horizontal pipe 803 and several connecting pipes 804, it forms a suction force in the receiving pipe 603, and sends the remaining concrete back into the storage box 8. After the repair is completed, the telescopic ends of the two first telescopic cylinders 6051 are retracted, and the cover plate 6 is reset through the push plate 605 and the connecting plate 604 until the template 3 slides up again, and the above-mentioned repair work is repeated.
