Description

Technical Field

[0001] This invention relates to the field of bridge main tower construction technology in civil engineering. More specifically, this invention relates to an industrialized construction equipment and method for cast-in-place piers. Background Technology

[0002] Currently, cast-in-place pier construction primarily employs methods such as formwork flipping, slipforming, or climbing formwork. However, existing equipment exhibits low levels of automation and intelligence in each stage of pier construction, resulting in poor quality of the cast-in-place pier body. This is mainly reflected in the following aspects:

[0003] 1. Existing equipment construction mainly relies on the main structure (pier body) for support. It is necessary to set embedded parts or tie rod holes on the main structure. After the pier body is formed, the holes are repaired. The quality of the cast-in-place pier body is not good. Especially for piers in the sea, the embedded holes or tie rod holes in the pier body will have a very adverse effect on the durability of the main structure of the pier body.

[0004] 2. The working environment for workers is harsh, and the protective platform is rudimentary; for higher piers, workers need to climb ladders up and down repeatedly.

[0005] 3. The efficiency and quality of loosely tied reinforcing bars are low;

[0006] 4. Special hoisting equipment needs to be installed next to the pier, but the equipment utilization rate is not high. Summary of the Invention

[0007] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0008] Another objective of this invention is to provide an industrialized construction equipment and method for cast-in-place piers, in order to solve the technical problems of low efficiency and poor forming quality in existing cast-in-place pier construction techniques.

[0009] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides an industrialized construction equipment for cast-in-place piers, comprising:

[0010] The column system includes columns symmetrically arranged on the outside of the pier structure on the pier platform. All columns are connected to a frame at their bottom. The bottom of the frame is fixed to the upper surface of the pier platform. The columns are made up of multiple standard segments connected in sequence. Slide rails are provided on the columns along the vertical direction.

[0011] The lifting system, which is set at the top of the column system and extends horizontally to the outside of the column, is used by the gantry crane to lift standard segments or construction components of the column for installation.

The vibration system extends towards the inner side and upward of the formwork system to vibrate the poured pier body concrete.

[0013] The self-elevating platform is set above the column system and between the vibration system and the hoisting system, serving as a platform for rebar tying and an interconnection platform between the hoisting system and the formwork system.

[0014] The self-elevating platform is located at the bottom of the column system and below the main support platform, serving as an interconnection platform for personnel to go up and down the main support platform;

[0015] The inner sides of the lifting system, main load-bearing platform, upper self-elevating platform, and lower self-elevating platform are respectively connected to the slide rails of the corresponding height range and are equipped with climbing mechanisms, which enable the platform to move up and down along the slide rails.

[0016] Preferably, the frame is a regular hexagon in horizontal cross-section, and four columns are provided at the four vertices of the frame, and the four columns are symmetrically arranged along the center line of the width direction of the pier.

[0017] Preferably, a pier-holding device is provided on the inner side of the main bearing platform facing the pier body. The pier-holding device is symmetrically arranged around the pier body. The pier-holding device includes a lead screw, a lead screw nut, a limiting sleeve, and a connector. The lead screw is driven to rotate by a motor, which is fixed on the main bearing platform. The lead screw is mounted on the main bearing platform through bearings. The lead screw nut is connected to the lead screw through threaded transmission. The limiting sleeve is sleeved on the outer side of the lead screw and the lead screw nut in a coaxial direction to limit the radial movement of the lead screw nut. A connector is connected on the side of the lead screw nut facing the pier body, and the shape of the connector is matched to the corresponding position of the pier body.

[0018] Preferably, the lifting system includes a load-bearing truss, which is a double-frame structure symmetrically arranged on the top outer sides of opposite sides of the column system. The top of the double-frame structure is provided with parallel rails, and a gantry crane is slidably connected on the two rails. A counterweight is provided at the top of the end of the two rails away from the gantry crane.

[0019] Preferably, the template system includes two C-shaped templates arranged opposite each other, with tie rods fastening between the ends of the two C-shaped templates respectively. A three-phase adjustment cylinder is provided at the bottom of each C-shaped template. The three-phase adjustment cylinder includes a vertical leveling cylinder, a mold opening cylinder and a horizontal adjustment cylinder, which are used to adjust the position of the C-shaped template in the vertical, width and length directions respectively.

[0020] Preferably, the construction climbing frame is provided with an upward vertical pole, the top of which extends above the formwork system and is rotatably connected to a horizontal frame. The outer end of the horizontal frame is connected to the vibration system, and the vibration system is rotated to the inner side above the C-shaped formwork or away from the formwork system via the horizontal frame.

[0021] On the other hand, the present invention also provides a method for using industrialized construction equipment for cast-in-place piers. The specific steps for constructing cast-in-place piers using the industrialized construction equipment are as follows:

[0022] S1. Complete the concrete pouring of the pier cap and the first section of the pier body;

[0023] S2. Install the frame at the bottom of the column system and the standard segment corresponding to the column on the outside of the first pier body, and install the lower self-elevating platform on the lower part of the column;

[0024] S3. Use the lower self-elevating platform as a steel reinforcement construction platform to install the steel reinforcement components of the second pier section;

[0025] S4. Install the main load-bearing platform in the middle of the column, and install the formwork system and the vibration system on the main load-bearing platform;

[0026] S5. After the formwork system is closed, the second section of the pier body concrete is poured. At the same time, the upper self-lifting platform is installed above the formwork system, and the lifting system is installed on the top of the column system.

[0027] S6. While the concrete of the second pier body reaches the same strength, the standard segment of the column is lifted and installed by the lifting system, and the column is continued upward. Then the lifting system climbs upward by the corresponding climbing mechanism.

[0028] S7. Use the lifting system to lift the steel reinforcement components of the third pier section, and then complete the installation of the steel reinforcement components on the upper self-elevating platform;

[0029] S8. The main load-bearing platform drives the formwork system to climb upward through the corresponding climbing mechanism. The formwork system closes the formwork corresponding to the steel reinforcement components at the third pier section. At the same time, the lower self-elevating platform cures the poured concrete.

[0030] S9. Pour the concrete for the third section of the pier body. While the concrete for the third section of the pier body is of equal strength, use the lifting system to lift and install the standard segment of the column, and then lift it upwards.

[0031] S10. Repeat steps S7-S9 until the pouring of all segments of the pier is completed.

[0032] Preferably, the vibration system is rotatably connected and installed on the top of the construction climbing frame. When installing the steel reinforcement components of a certain section of the pier, the vibration system is operated to rotate away from the formwork system to make room for the installation of the steel reinforcement components. When pouring the pier concrete, it is rotated to be directly above the pier concrete for vibration.

[0033] The present invention has at least the following beneficial effects: The industrialized construction equipment for cast-in-place piers of the present invention is set on the outside of the pier body to form an integrated pier construction factory. With the column system as support, there is no need to set embedded parts or tie rod holes in the main structure, which will not damage the structure of the pier body itself and ensure the casting quality of the pier body. The lifting system, main bearing platform, upper self-elevating platform and lower self-elevating platform are all equipped with climbing mechanisms, which can climb upward as the standard column segments in the column system are heightened, realizing continuous cast-in-place construction of the pier body. The upper self-elevating platform and the lower self-elevating platform serve as docking channels and simple construction platforms between the lifting system, the formwork system and the ground, improving construction efficiency and allowing for flexible up and down movement. Especially for taller piers, it provides workers with a construction platform with a good access environment, reduces climbing distance, and significantly improves construction safety.

Therefore, they should not be construed as limitations on this invention.

[0053] like Figure 1-5 As shown, the present invention provides an industrialized construction equipment for cast-in-place piers, comprising:

[0054] The column system includes columns 3 symmetrically arranged on the outer side of the pier body 2 structure on the pier cap 1. The bottom of all columns 3 is connected to a frame 4. The bottom of the frame 4 is fixed to the upper surface of the pier cap 1. The columns 3 are composed of multiple standard segments 5 connected in sequence. Slide rails are provided vertically on the columns 3.

[0055] The lifting system 6 is set at the top of the column system and extends horizontally to the outside of the column 3. The gantry crane 17 is used to lift the standard segment 5 or construction components of the column 3.

[0056] The main load-bearing platform 7 is located in the middle of the column system. A formwork system 10 is provided on the main load-bearing platform 7 corresponding to the pier body 2. A construction climbing frame 11 is provided on the outside of the formwork system 10. A vibration system 12 is provided on the top of the construction climbing frame 11. The vibration system 12 extends towards the inner side and above the formwork system 10 and is used to vibrate the concrete of the poured pier body 2.

[0057] The self-elevating platform 8 is set on the upper part of the column system and located between the vibration system 12 and the lifting system 6, serving as a platform for rebar tying and an interconnection platform between the lifting system 6 and the formwork system 10.

[0058] The self-elevating platform 9 is located at the bottom of the column system and below the main support platform 7, serving as an interconnection platform for personnel to go up and down the main support platform 7.

[0059] The inner sides of the lifting system 6, the main bearing platform 7, the upper self-elevating platform 8, and the lower self-elevating platform 9 are respectively connected to the slide rails of the corresponding height range and are equipped with climbing mechanisms 23, which enable the lifting system 6, the main bearing platform 7, the upper self-elevating platform 8, and the lower self-elevating platform 9 to move up and down along the slide rails.

[0060] On the outer side of the pier body 2 to be poured, the foundation 1 is used as a fixed support base to install the column system. A climbing rail is installed on the column system. From top to bottom, the column system is used to install the lifting system 6, the upper self-elevating platform 8, the main load-bearing platform 7, and the lower self-elevating platform 9. The main load-bearing platform 7 serves as the installation platform for the formwork system 10. The lifting system 6 is used to lift the steel reinforcement components 13, equipment, and standard sections 5 of the columns 3. The upper and lower self-elevating platforms 8 and 9 serve as access routes for workers and operating platforms for corresponding construction stages. The upper self-elevating platform 8 serves as the access route between the lifting system 6 and the main load-bearing platform 7. It also facilitates the binding and installation of the steel reinforcement components 13 and the vibration of the concrete. The vibration system is equipped with an automatic vibration quality monitoring platform that can display the real-time performance of each part. For vibration quality, the lower self-elevating platform 9 serves as the vertical passage between the main load-bearing platform 7 and the ground. A curing system can be installed on the lower self-elevating platform 9 to coordinate concrete curing operations. The curing system generally includes a closed system, an integrated intelligent curing machine, and a corresponding control system. The closed system covers the poured concrete sections with modular curing tarpaulins and uses spray curing pipes for humidification and cooling. The integrated intelligent curing machine mainly includes a heating device, a humidification device, and a wireless receiving and control device. The control system includes temperature and humidity sensors deployed on the poured concrete, a data receiving terminal, a controller, and a remote display terminal, enabling real-time data acquisition, data analysis, storage and retrieval, and intelligent control. The control system communicates with the wireless receiving device and can control the heating and humidification functions of the integrated intelligent curing machine. All climbing mechanisms 23 can uniformly adopt a hydraulic system and reversing box similar to those used in traditional climbing formwork construction, along with slide rails. Climbing brackets are set on the columns 3, or claw holes are set on the slide rails as in patent number 202110390697.8, and upper and lower climbing box structures are set. The upper and lower climbing boxes are respectively equipped with limiting mechanisms for controlling the flipping direction of the corresponding self-balancing claws. A lifting cylinder is set vertically between the upper and lower climbing boxes to achieve the climbing of the corresponding structure.

[0061] The industrialized construction equipment for cast-in-place piers of this invention forms an integrated pier-building factory on the outside of the pier body 2. With the column system as support, it eliminates the need for embedded parts or tie rod holes in the main structure, thus preventing damage to the pier body 2 itself and ensuring the casting quality of the pier body 2. The lifting system 6, main bearing platform 7, upper self-elevating platform 8, and lower self-elevating platform 9 are all equipped with climbing mechanisms 23, which can climb upwards as the columns 3 in the column system increase in height, realizing continuous cast-in-place construction of the pier body. The upper self-elevating platform 8 and lower self-elevating platform 9 serve as connecting channels and simple construction platforms between the lifting system 6, the formwork system 10, and the ground, improving construction efficiency and allowing for flexible vertical movement. Especially for the taller pier body 2, they provide workers with a construction platform with a good access environment, reducing climbing distance and significantly improving construction safety.

[0062] In another technical solution, such as Figure 3-4 As shown, the frame 4 is a regular hexagon in horizontal cross section, and four columns 3 are provided at the four vertices of the frame 4, and the four columns 3 are symmetrically arranged along the center line of the width direction of the pier body 2.

[0063] Based on the cross-sectional structural characteristics of the pier body 2, four columns 3 are set along the four vertices of the rectangle and are connected and reinforced by a regular hexagonal bottom frame 4. The two ends of the wide side of the rectangular cross-section mainly serve as the symmetrical installation sides of the climbing mechanism 23, and the two ends of the long side of the rectangular cross-section serve as the opening and closing directions of the formwork system 10, thereby improving the utilization rate of space and the stability of the structural support.

[0064] In another technical solution, such as Figure 5 As shown, a pier-holding device 14 is provided on the inner side of the main bearing platform 7 facing the pier body 2. The pier-holding device 14 is symmetrically arranged around the pier body 2. The pier-holding device 14 includes a lead screw, a lead screw nut, a limiting sleeve, and a connector 15. The lead screw is driven to rotate by a motor, which is fixed on the main bearing platform 7. The lead screw is mounted on the main bearing platform 7 through bearings. The lead screw nut is connected to the lead screw through threaded transmission. The limiting sleeve is sleeved on the outside of the lead screw and the lead screw nut in a coaxial direction to limit the radial movement of the lead screw and nut. The connector 15 is connected on the side of the lead screw and nut facing the pier body 2. The shape of the connector 15 is matched with the corresponding position of the pier body 2.

[0065] By setting up the pier-holding device 14, when the pier is in place, the motor screw nut moves outward in a straight line under the limiting action of the limiting sleeve, so that the joint 15 extends out to hold the cast-in-place pier body 2, further ensuring the stability of the entire cast-in-place pier industrial construction equipment. When climbing is required, the joint 15 is retracted by rotating the screw in the opposite direction.

[0066] In another technical solution, such as Figure 10-11As shown, the lifting system 6 includes a load-bearing truss 16, which is a double-frame structure symmetrically arranged on the top outer sides of opposite sides of the column system. Parallel tracks are arranged on the top of the double-frame structure, and a gantry crane 17 is slidably connected to both tracks. A counterweight 18 is installed at the top of the end of each track furthest from the gantry crane 17. The gantry crane 17 can lift and install standard segments 5 of the column 3, realizing the self-erecting function of the column pier factory.

[0067] In another technical solution, such as Figure 3-4 As shown, the template system 10 includes two C-shaped templates 19 arranged opposite each other. Tie rods are provided between the ends of the two C-shaped templates 19 for fastening. A three-phase adjustment cylinder 20 is provided at the bottom of each C-shaped template 19. The three-phase adjustment cylinder 20 includes a vertical leveling cylinder, a mold opening cylinder and a horizontal adjustment cylinder, which are used to adjust the position of the C-shaped template 19 in the vertical, width and length directions respectively.

[0068] Based on the cross-sectional shape of the pier body 2, the formwork system 10 is divided into two C-shaped formwork 19s along the short side. The two C-shaped formwork 19s are connected by tie rods to ensure the tightness after the formwork is closed. The three-phase adjustment cylinder 20 accurately adjusts the position of the formwork in the length, width and height directions to improve the efficiency of formwork installation and dismantling.

[0069] In another technical solution, such as Figure 1 As shown, the construction climbing frame 11 is provided with a vertical rod 21. The top of the vertical rod 21 extends above the template system 10 and is rotatably connected to a horizontal frame 22. The outer end of the horizontal frame 22 is connected to the vibration system 12. The vibration system 12 is rotated to the inner side above the C-shaped template 19 or away from the template system 10 via the horizontal frame 22.

[0070] By setting a horizontal frame 22 on the top of the construction climbing frame 11 outside the formwork system 10 and then connecting it to the vibration system 12, the position of the vibration system 12 can be adjusted according to construction needs, making room for the hoisting, binding and installation of the steel reinforcement components 13.

[0071] This invention also provides an industrialized construction method for cast-in-place piers, combined with... Figure 6-14 As shown, the specific steps for constructing cast-in-place piers using industrialized cast-in-place pier construction equipment are as follows:

[0072] S1, such as Figure 6 As shown, the concrete pouring of the pier cap 1 and the first section of the pier body 2 has been completed.

[0073] S2, such as Figure 7As shown, the frame 4 at the bottom of the column system and the standard segment 5 corresponding to the column 3 are installed on the outside of the first pier section 2, and the lower self-lifting platform 9 is installed on the lower part of the column 3. At this time, the height of the column 3 ensures that it covers the construction range of the two pier sections 2.

[0074] S3, such as Figure 8 As shown, the lower self-elevating platform 9 is used as a steel reinforcement construction platform to install the steel reinforcement components 13 of the second pier body 2.

[0075] S4, such as Figure 9 As shown, the main load-bearing platform 7 is installed in the middle of the column 3, and the formwork system 10 and the vibration system 12 are installed on the main load-bearing platform 7. The lower self-lifting platform 9 is used as the upper and lower passage. The main load-bearing platform 7 is installed upward within the height range of the first pier section 2. The main load-bearing platform 7 is lifted to the height of the steel reinforcement components 13 of the second pier section 2, and the vibration system 12 is installed.

[0076] S5, such as Figure 10 As shown, after the formwork system 10 is closed, the second section of the pier body 2 is poured with concrete. At the same time, the upper self-lifting platform 8 is installed above the formwork system 10, and the lifting system 6 is installed on the top of the column system. At this time, the installation of all functional systems of the cast-in-place pier industrialized construction equipment is completed.

[0077] S6, such as Figure 11 As shown, while the concrete of the second pier section 2 is of equal strength, the standard segment 5 of the column 3 is lifted and installed by the lifting system 6, and the column 3 is continued upward, so that the entire cast-in-place pier industrialized construction equipment can cover the construction needs of the height range of the next pier section 2. Then the lifting system 6 climbs upward through the corresponding climbing mechanism 23.

[0078] S7, such as Figure 12 As shown, the lifting system 6 is used to lift the steel reinforcement component 13 of the third pier body 2, and then the installation of the steel reinforcement component 13 is completed on the upper self-elevating platform 8.

[0079] S8, such as Figure 13 As shown, the main bearing platform 7 drives the formwork system 10 to climb upward through the corresponding climbing mechanism 23. The formwork system 10 is closed at the third section of the pier body 2, corresponding to the steel reinforcement component 13. At the same time, the lower self-elevating platform 9 serves as the installation docking platform for the curing system on the main bearing platform 7. After the curing system is installed, the poured concrete is cured.

[0080] S9, such as Figure 14As shown, the concrete of the third section of the pier body 2 is poured. While the concrete of the third section of the pier body 2 is of equal strength, the standard segment 5 of the column 3 is lifted and installed upward by the lifting system 6 and then climbs upward.

[0081] S10. Repeat steps S7-S9 until the pouring of all segments of pier 2 is completed.

[0082] By utilizing industrialized construction equipment for cast-in-place piers, the entire pier body 2 can be cast in place simultaneously. This allows for the simultaneous lifting, binding, molding, concrete pouring, and curing of different sections of the pier body 2's reinforcing steel components 13. Furthermore, the different structures of the industrialized construction equipment for cast-in-place piers can be installed synchronously as the pier body 2 sections are constructed upwards, significantly improving construction efficiency.

[0083] In another technical solution, the vibration system 12 is rotatably connected to the top of the construction climbing frame 11. When installing the steel reinforcement component 13 of a certain section of the pier body 2, the vibration system 12 is operated to rotate away from the formwork system 10 to make room for the installation of the steel reinforcement component 13. When pouring the concrete of the pier body 2, it is rotated to be directly above the concrete of the pier body 2 for vibration.

[0084] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
