Description

Technical Field

[0001] This invention relates to the field of climbing formwork technology for bridge pier construction, and in particular to a long-stroke climbing method for climbing formwork. Background Technology

[0002] The applicant's previous Chinese patent application, 201410774891.6, disclosed an integrated device for bridge climbing formwork and hanging basket. The device includes a climbing formwork device with a main load-bearing longitudinal beam 1 and a main load-bearing transverse beam 2 at the top. The main load-bearing longitudinal beam 1 is connected to a bottom load-bearing longitudinal beam 4 and a bottom load-bearing transverse beam 5 at the bottom of the climbing formwork device via a support beam 3. The support beam 3 is connected to a climbing formwork mechanism 6, and the bottom load-bearing longitudinal beam 4 and bottom load-bearing transverse beam 5 are connected to a load-bearing vertical beam 7. The components of the climbing formwork device can be converted into components of a hanging basket. The traveling mechanism of the climbing formwork mechanism 6 includes a climbing formwork cylinder 17, which is connected to a lower chuck 18. The lower chuck 18 is connected to a climbing formwork track 19. When the climbing formwork device travels, the climbing formwork mechanism 6 is raised by adjusting the climbing formwork cylinder 17 and the lower chuck 18 until the device reaches the required distance. Then, a load-bearing wedge is inserted to fix the formwork.

[0003] The applicant has found through long-term use that the climbing scaffold rails have the following problems and disadvantages: The structure is complex, the rails need to be attached to the piers, and the installation time is long. The hydraulic cylinders are attached to the lower chuck and the climbing scaffold rails, resulting in a short climbing stroke, requiring multiple climbs to reach the climbing height of one segment, and a long climbing time. Summary of the Invention

[0004] The purpose of this invention is to provide a long-stroke climbing method for climbing scaffolds. It features a simple structure, convenient installation, and a long climbing stroke.

[0005] The technical solution of this invention: a long-stroke climbing method for climbing scaffolds, comprising the following steps,

[0006] 1. When casting the first and second segments of the pier column on the pier cap 1 using the vertical formwork casting method, make multi-layered pre-embedded holes for load-bearing wedges on the large surface of the pier column;

[0007] 2. Insert load-bearing wedges into the pre-embedded holes in the first layer below;

[0008] 3. Suspend and install low-load-bearing wedge brackets and high-load-bearing wedge brackets on the load-bearing wedges;

[0009] 4. Install two platform crossbeams on the large surface of the pier column, respectively, and fit them into the slots of the low load-bearing wedge bracket and the high load-bearing wedge bracket and fix them in place;

[0010] 5. The platform beams below the large and small faces of the pier column are connected by beam clamps to form the lower platform;

[0011] 6. Install the hydraulic cylinder connector onto the lower platform crossbeam and secure it with bolts;

[0012] 7. Connect the cylinder barrel tailstock to the cylinder connector using bolts;

[0013] 8. Ensure the cylinder barrel and piston rod are assembled vertically upwards;

[0014] 9. Insert the load-bearing wedge into the pre-embedded hole of the third layer of load-bearing wedges above;

[0015] 10. Suspend and install the low-load-bearing wedge bracket and the high-load-bearing wedge bracket on the upper load-bearing wedge;

[0016] 11. Install two platform crossbeams on the main surface of the pier column, respectively, and fit them into the slots of the low-load-bearing wedge bracket and the high-load-bearing wedge bracket and fix them in place;

[0017] 12. The platform beams above the large and small faces of the pier are connected by beam clamps to form the upper platform;

[0018] 13. Install the hydraulic cylinder connector onto the upper platform beam and secure it with bolts;

[0019] 14. Connect the piston rod lug of the hydraulic cylinder to the hydraulic cylinder connector by bolts;

[0020] 15. Ensure the cylinder barrel and piston rod of the hydraulic cylinder are assembled vertically upwards;

[0021] 16. The upper and lower platforms are connected by hydraulic cylinders to form a mutually supportive bidirectional lifting mechanism.

[0022] The load-bearing wedge is fixed at an angle in the pre-embedded hole. The upper part of the low load-bearing wedge holder and the high load-bearing wedge holder are connected to the load-bearing wedge through a groove, and the lower part is connected to the platform beam through a slot. The groove and slot of the low load-bearing wedge holder and the high load-bearing wedge holder have a height difference, so that the groove and slot form an inclination angle. The inclination angle is consistent with the inclination angle of the load-bearing wedge in the pre-embedded hole.

[0023] When the load-bearing wedge of the lower platform is inserted into the pre-embedded hole, that is, when the lower platform is fixed as a support, the load-bearing wedge of the upper platform is removed, the hydraulic cylinder is activated, the piston rod is extended, and the hydraulic cylinder will drive the entire upper platform to move upward. When the upper platform moves to the fourth pre-embedded hole above, the load-bearing wedge of the upper platform is inserted into the fourth pre-embedded hole above.

[0024] When the load-bearing wedge of the upper platform is inserted into the pre-embedded hole, that is, when the upper platform is fixed as a support, the load-bearing wedge of the lower platform is removed, the hydraulic cylinder is activated, and the piston rod of the hydraulic cylinder is retracted. The hydraulic cylinder will then drive the entire lower platform to rise. When the lower platform moves to the second pre-embedded hole above, the load-bearing wedge of the upper platform is inserted into the second pre-embedded hole above.

[0025] When the load-bearing wedge is fixed at an angle of 8-12° with the parallel line in the pre-embedded hole.

[0026] The platform is stabilized by a tripod beneath the crossbeam, and the tripod moves along the side of the pier column using rollers.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention uses load-bearing wedges and pre-embedded holes as the load-bearing foundation for the climbing scaffold. Only pre-embedded holes need to be left on the piers; no other components need to be pre-embedded, and there is no need for welding, bolts, or other connections in the pre-embedded holes. The structure is simple and construction is quick. The load-bearing wedges are inserted obliquely into the pre-embedded holes and will not come out under gravity, ensuring a firm connection. Through the height difference between the low-load-bearing wedge holder and the high-load-bearing wedge holder, a stable connection with the platform beam can be achieved, ensuring that the hydraulic cylinders can be installed vertically on the platform beam. During climbing, all hydraulic cylinders can output power vertically without tilting, resulting in small synchronization errors and high climbing efficiency.

[0029] 2. In this invention, the hydraulic cylinder is directly connected to the upper and lower platform beams, eliminating the need for climbing frame tracks. The stroke distance is the extension and retraction distance of the piston rod of the hydraulic cylinder, no longer limited by the climbing frame tracks. Therefore, the climbing stroke is long, and a pier segment (4.5 meters) can be climbed in two steps, saving climbing time and the cost of climbing rails and other components.

Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0036] Embodiment 1 of the present invention: A long-stroke climbing method for climbing scaffolds, comprising the following steps,

[0037] 1. When casting the first segment 2 and the second segment 3 of the pier column on the pier cap 1 using the vertical formwork casting method, make multi-layered pre-embedded holes 4 for load-bearing wedges on the large surface of the pier column;

[0038] 2. Insert a load-bearing wedge 5 into the pre-embedded hole 4 in the first layer below;

[0039] 3. Suspend and install the low-load-bearing wedge bracket 6 and the high-load-bearing wedge bracket 7 on the load-bearing wedge 5;

[0040] 4. Install two platform beams 8 on the large surface of the pier column, respectively, and fit them into the slots 13 of the low load-bearing wedge bracket 6 and the high load-bearing wedge bracket 7 and fix them in place;

[0041] 5. The platform beams 8 below the large face and the small face of the pier are connected by beam clamps 14 to form a lower platform;

[0042] 6. Install the hydraulic cylinder connector 9 onto the lower platform beam 8 and secure it with bolts;

[0043] 7. The cylinder barrel 10 tailstock of the hydraulic cylinder is connected to the hydraulic cylinder connector 9 by bolts;

[0044] 8. Ensure that the cylinder barrel 10 and piston rod 11 are assembled vertically upwards in place;

[0045] 9. Insert the load-bearing wedge 5 into the pre-embedded hole 4 of the third layer of load-bearing wedges above;

[0046] 10. Suspend and install the low-load-bearing wedge bracket 6 and the high-load-bearing wedge bracket 7 on the upper load-bearing wedge 5;

[0047] 11. Install two platform beams 8 on the large surface of the pier column, respectively, and fit them into the slots 13 of the low load-bearing wedge bracket 6 and the high load-bearing wedge bracket 7 and fix them.

[0048] 12. The platform beams 8 above the large and small faces of the pier are connected by beam clamps 14 to form the upper platform;

[0049] 13. Install the hydraulic cylinder connector 9 onto the upper platform beam 8 and secure it with bolts;

[0050] 14. The piston rod 11 lug of the hydraulic cylinder is bolted to the hydraulic cylinder connector 9;

[0051] 15. Ensure that the cylinder barrel 10 and piston rod 11 are assembled vertically upwards in place;

[0052] 16. The upper and lower platforms are connected by hydraulic cylinders to form a mutually supportive bidirectional lifting mechanism.

[0053] The load-bearing wedge 5 is fixed at an angle in the pre-embedded hole 4. The upper part of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 are connected to the load-bearing wedge 5 through the inclined groove 12, and the lower part is connected to the platform beam 8 through the slot 13. The inclined groove 12 and the slot 13 of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 have a height difference, so that the inclined groove 12 and the slot 13 form an inclined angle. The inclined angle is consistent with the inclined angle of the load-bearing wedge 5 in the pre-embedded hole 4.

[0054] When the load-bearing wedge 5 of the lower platform is inserted into the pre-embedded hole 4, that is, when the lower platform is fixed as a support, the load-bearing wedge 5 of the upper platform is removed, the hydraulic cylinder is activated, the piston rod 11 is extended, and the hydraulic cylinder will drive the entire upper platform to move upward. When the upper platform moves to the fourth pre-embedded hole 4 above, the load-bearing wedge 5 of the upper platform is inserted into the fourth pre-embedded hole 4 above.

[0055] When the load-bearing wedge 5 of the upper platform is inserted into the pre-embedded hole 4, that is, when the upper platform is fixed as a support, the load-bearing wedge 5 of the lower platform is removed, the hydraulic cylinder is activated, and the piston rod 11 of the hydraulic cylinder is retracted. The hydraulic cylinder will then drive the entire lower platform to rise. When the lower platform moves to the second pre-embedded hole 4 above, the load-bearing wedge 5 of the upper platform is inserted into the second pre-embedded hole 4 above.

[0056] When the load-bearing wedge 5 is fixed at an angle of 8-12° with the parallel line in the pre-embedded hole 4, it is inclined.

[0057] The platform beam 8 is supported by a tripod 15 to keep the lower platform stable. The tripod 15 moves along the side of the pier column via rollers.

[0058] The cylinder stroke is 2450mm. To allow for adjustment, a 200mm margin is provided. Each lift can be 2250mm, and two lifts can raise it to a height of 4.5m.

[0059] Repeat the above actions, and the lifting mechanism can drive the upper and lower platforms to rise alternately, completing the lifting of all platforms from the first segment of the pier to all segments above the second segment.

[0060] A long-stroke climbing method for a climbing scaffold employs the following structure: upper and lower load-bearing wedges 5, with a low-load-bearing wedge seat 6 and a high-load-bearing wedge seat 7 connected to the load-bearing wedges 5. The lower and higher load-bearing wedge seats 6 and 7 are respectively connected to the upper and lower platform beams 8. The cylinder barrel 10 and piston rod 11 of a hydraulic cylinder are connected to the upper and lower platform beams 8 via hydraulic cylinder connectors 9. The hydraulic cylinder is connected for load-bearing and lifting via the platform beams 8 of the climbing scaffold, resulting in a simpler structure.

[0061] The load-bearing wedge 5 is fixed at an angle in the pre-embedded hole 4. The upper part of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 is provided with a groove 12 that connects to the load-bearing wedge 5, and the lower part is provided with a slot 13 that connects to the platform beam 8. The groove 12 and the slot 13 of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 have a height difference. The angle of inclination formed by the groove 12 and the slot 13 is consistent with the angle of inclination of the load-bearing wedge 5. This allows the load-bearing wedge 5 to be firmly locked in the pre-embedded hole 4 when bearing weight, and to be easily removed from the pre-embedded hole 4 when not bearing weight. The low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 can make the connection between the inclined load-bearing wedge 5 and the horizontally set platform beam 8 stable.

[0062] The angle between the load-bearing wedge 5 and the parallel line is 8-12°, and more preferably 10°.

[0063] The pre-embedded holes 4 are set on the two large faces of the pier column, with 2 holes on each face and 4 holes on each layer. The climbing action is performed by 4 hydraulic cylinders, which makes it more stable.

[0064] A tripod 15 is installed below the platform beam 8. The side of the tripod 15 facing the pier is equipped with rollers, which can make the entire platform more stable.

[0065] The platform beam 8 is connected to the platform via beam clamps 14.

[0066] The hydraulic cylinder connector 9 includes a horizontal plate 91 with holes 92, with inclined extension plates 93 connected to both ends of the horizontal plate 91, and a crossbeam holder 94 connected to the other end of the extension plate 93. A limiting hole 95 is provided on the other end of the extension plate 93, and a crossbeam holder 94 is provided with a crossbeam slot 96 for connecting the platform crossbeam 8.

[0067] The installation process of the hydraulic cylinder connector 9 is as follows: Install two crossbeam brackets 94 on the two lower platform crossbeams 8. Insert the extension plate 93 of the hydraulic cylinder connector 9 into the limiting groove of the crossbeam bracket 94. Then, insert bolts into the limiting holes 95 to fix the extension plate 93 and the crossbeam bracket 94. Install two crossbeam brackets 94 on the two upper platform crossbeams 8. Insert the connector 3 of the hydraulic cylinder lug 1 into the limiting groove 41 of the crossbeam bracket 4. Insert the extension plate 93 of the hydraulic cylinder connector 9 into the limiting groove of the crossbeam bracket 94. Then, insert bolts into the limiting holes 95 to fix the extension plate 93 and the crossbeam bracket 94. The installation of the upper and lower hydraulic cylinder connectors 9 is completed. The tailstock of the hydraulic cylinder barrel 10 is installed on the lower horizontal plate 91 through the hole 92 and the connecting pin. The front end lug of the hydraulic cylinder piston rod 11 is installed on the upper horizontal plate 91 through the hole 92 and the connecting pin. The upper and lower platforms can be fixed or released from the bridge piers respectively. By extending and retracting the hydraulic cylinders, the upper and lower platforms can be raised or lowered relative to each other.

[0068] The extension plate 93 forms an angle of 30-60° with the parallel line, and the extension plate 93 extends upward or downward simultaneously. By extending the extension plate 93 upward or downward, the stroke of the hydraulic cylinder can be increased or decreased, allowing different specifications of hydraulic cylinders to match the stroke of the climbing frame. Furthermore, when the two ends of the hydraulic cylinder are connected to the horizontal plate 91 with holes 92, the ends and the platform crossbeam 8 are not on the same plane, forming a staggered installation, which facilitates construction. Figure 3 As shown, the extension plates 93 on both sides of the lower cylinder connector 9 extend upwards simultaneously, while the extension plates 93 on both sides of the upper cylinder connector 9 extend downwards simultaneously, which can shorten the stroke of the cylinder 6. Conversely, the extension plates 93 on both sides of the lower cylinder connector 9 extend downwards simultaneously, while the extension plates 93 on both sides of the upper cylinder connector 9 extend upwards simultaneously, which can increase the stroke of the cylinder.

[0069] Embodiment 2 of the present invention: A long-stroke climbing method for a climbing scaffold includes upper and lower load-bearing wedges 5, with a low-load-bearing wedge seat 6 and a high-load-bearing wedge seat 7 connected to the load-bearing wedges 5. The lower and higher load-bearing wedge seats 6 and 7 are respectively connected to upper and lower platform beams 8. The cylinder barrel 10 and piston rod 11 of a hydraulic cylinder are respectively connected to the upper and lower platform beams 8 via hydraulic cylinder connectors 9. The hydraulic cylinder is connected for load-bearing and lifting via the platform beams 8 of the climbing scaffold, resulting in a simpler structure.

[0070] The load-bearing wedge 5 is fixed at an angle in the pre-embedded hole 4. The upper part of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 is provided with a groove 12 that connects to the load-bearing wedge 5, and the lower part is provided with a slot 13 that connects to the platform beam 8. The groove 12 and the slot 13 of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 have a height difference. The angle of inclination formed by the groove 12 and the slot 13 is consistent with the angle of inclination of the load-bearing wedge 5. This allows the load-bearing wedge 5 to be firmly locked in the pre-embedded hole 4 when bearing weight, and to be easily removed from the pre-embedded hole 4 when not bearing weight. The low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 can make the connection between the inclined load-bearing wedge 5 and the horizontally set platform beam 8 stable.

[0071] The angle between the load-bearing wedge 5 and the parallel line is 9-11°.

[0072] Each side of the pier can be equipped with two or more pre-embedded holes, and corresponding hydraulic cylinders can be installed to perform climbing actions, which can be applied to large-volume piers.

[0073] The platform beam 8 is connected to the platform through existing connecting parts.

[0074] A long-stroke climbing method for climbing scaffolds includes the following steps:

[0075] 1. When casting the first segment 2 and the second segment 3 of the pier column on the pier cap 1 using the vertical formwork casting method, make multi-layered pre-embedded holes 4 for load-bearing wedges on the large surface of the pier column;

[0082] 8. Ensure that the cylinder barrel 10 and piston rod 11 are assembled vertically upwards in place;

[0083] 9. Insert the load-bearing wedge 5 into the pre-embedded hole 4 of the third layer of load-bearing wedges above;

[0089] 15. Ensure that the cylinder barrel 10 and piston rod 11 are assembled vertically upwards in place;

[0090] 16. The upper and lower platforms are connected by hydraulic cylinders to form a mutually supportive bidirectional lifting mechanism.

[0091] The load-bearing wedge 5 is fixed at an angle in the pre-embedded hole 4. The upper part of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 are connected to the load-bearing wedge 5 through the inclined groove 12, and the lower part is connected to the platform beam 8 through the slot 13. The inclined groove 12 and the slot 13 of the low load-bearing wedge holder 6 and the high load-bearing wedge holder 7 have a height difference, so that the inclined groove 12 and the slot 13 form an inclined angle. The inclined angle is consistent with the inclined angle of the load-bearing wedge 5 in the pre-embedded hole 4.

[0092] When the load-bearing wedge 5 of the lower platform is inserted into the pre-embedded hole 4, that is, when the lower platform is fixed as a support, the load-bearing wedge 5 of the upper platform is removed, the hydraulic cylinder is activated, the piston rod 11 is extended, and the hydraulic cylinder will drive the entire upper platform to move upward.
