Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a truss type hydraulic self-climbing formwork. Background Art

[0002] Hydraulic climbing formwork is an innovative construction technology that combines the efficiency of slipform construction with the quality advantages of formwork technology. It achieves self-climbing of the formwork through hydraulic drive.

[0003] This hydraulic climbing formwork is often used during bridge construction. For example, the Wanbaoshan Bridge, spanning the Shibadaogou River and the Y203, spans 1,858 meters from K107+831 to K109+689, with a maximum height of 99.3 meters. The span layout and structure are 13 sections, consisting of 2 (4×40) + 1 (3×40) meter precast prestressed concrete T-beams + 1 (65+120+65) meter prestressed concrete continuous rigid frame + 7 (3×40) + 2 (4×40) meter precast prestressed concrete T-beams, with separate left and right lines. The substructure consists of column and hollow piers, with bored cast-in-place pile foundations. The abutments are column abutments with bored cast-in-place pile foundations.

[0004] The project employed a hydraulic self-climbing formwork system for piers over 50 meters tall, while piers under 50 meters were constructed using a PJ200 cantilever frame. The PJ200 cantilever frame required a tower crane for auxiliary lifting. The hydraulic self-climbing formwork is powered by its own hydraulic jacking system, which includes a hydraulic cylinder and upper and lower reversing boxes. The reversing boxes control the lifting of guide rails or the frame. The hydraulic system allows the formwork frame and guide rails to climb against each other, allowing the hydraulic self-climbing formwork to steadily ascend. The hydraulic self-climbing formwork eliminates the need for additional lifting equipment during construction, offering easy operation, rapid climbing speed, and a high safety factor. It is the preferred formwork system for high-rise building construction.

[0005] Existing hydraulic self-climbing formwork systems typically utilize a rack-and-pinion transmission mechanism to drive the formwork away from the concrete wall during the demolding process. Specifically, a rack is installed at the bottom of the demolding frame, and a meshing gear is positioned below the rack. A hydraulic motor or electric motor drives the gear to rotate, thereby driving the rack to move horizontally, ultimately separating the formwork from the concrete wall. However, this method has the following drawbacks: First, the driving force required is excessive: Due to the large contact area between the formwork and the concrete wall, the adsorption and friction between the two are extremely strong, and the gears must output a huge torque to overcome the resistance, causing the transmission system to be highly loaded during the demolding process. Second, the integrity of the wall surface is compromised: Excessive instantaneous driving force can easily cause the formwork to pull rigidly against the wall, causing peeling or scratching of the concrete surface, affecting the wall's surface quality and structural durability. Third, the transmission mechanism has low reliability: The gears are prone to tooth fracture (chipping) or excessive wear under continuous high-load conditions. Especially when the rack is not accurately installed, meshing misalignment will further accelerate failure, increasing maintenance costs and construction risks.

[0006] In summary, the hydraulic self-climbing formwork system in the prior art has the problems of excessive driving force requirement and low reliability of the transmission mechanism. Summary of the Invention

[0007] The present invention provides a truss-type hydraulic self-climbing formwork, which can solve the problems of excessive driving force requirement and low reliability of transmission mechanism in the hydraulic self-climbing formwork system in the prior art.

[0008] A truss-type hydraulic self-climbing formwork is arranged on the outside of the wall and comprises an upper frame and a lower frame arranged below the upper frame;

[0009] The lower frame includes a guide rail, a side frame connected to the guide rail, and a climbing formwork cylinder assembly provided on the side frame. The side frame includes a lower platform frame and a load-bearing tripod provided on the top of the lower platform frame.

[0010] Two wall-mounted mounts are provided on the guide rail, and the wall-mounted mounts are fixedly arranged on the outside of the wall;

[0011] The upper frame includes a top platform and a template frame arranged below the top platform, the template frame includes a first mounting template and an upper platform frame arranged on the side of the first mounting template, the upper platform frame includes a second vertical pole, a second crossbeam rotatably arranged at the lower end of the second vertical pole, and a translation assembly arranged at the lower end of the second crossbeam, and the translation assembly is used to drive the second crossbeam to move.

[0012] Furthermore, the wall-mounted hanging seat is provided with embedded parts, and the wall-mounted hanging seat is fixed to the wall through the embedded parts.

[0013] Furthermore, the embedded parts include an embedded plate, a high-strength screw provided on the embedded plate, a climbing cone provided on the outside of the high-strength screw, and a stress-bearing bolt, and the embedded plate, high-strength screw, and climbing cone are all provided in the wall;

[0014] A threaded mounting hole 1 is provided at one end of the climbing cone away from the high-strength screw rod and matched with the stressed bolt;

[0015] The wall-mounted mounting seat is provided with a second threaded mounting hole matched with a stress-bearing bolt. The stress-bearing bolt passes through the second threaded mounting hole and is screwed into the first threaded mounting hole.

[0016] Furthermore, the load-bearing tripod includes a first crossbeam, a first vertical pole arranged at the lower left end of the first crossbeam, and a first diagonal brace. The first crossbeam and the first vertical pole are connected in an L shape, and the two ends of the first diagonal brace are respectively connected to the first crossbeam and the first vertical pole.

[0017] Furthermore, a crossbeam hook is provided at the left end of the first vertical pole;

[0018] The crossbeam hook is cooperatively arranged on the wall hanging seat.

[0019] Furthermore, a wall support is provided on the side of the first vertical pole.

[0020] Furthermore, a second installation template is provided on the inner side of the wall;

[0021] A plurality of tension screws are provided in the wall, and screw mounting pieces are provided at both ends of each tension screw. The two screw mounting pieces are respectively provided on the first mounting template and the second mounting template.

[0022] Furthermore, a second diagonal brace is provided on one end of the second crossbeam away from the second vertical rod, and the second diagonal brace is rotatably provided on the second crossbeam;

[0023] One end of the second diagonal support away from the second crossbeam is rotatably arranged on the second vertical pole.

[0024] Furthermore, the translation assembly includes a translation guide rail, a driving mechanism and a driving gear, and the driving mechanism is used to drive the driving gear to rotate;

[0025] The second crossbeam is slidably arranged on the translation guide rail;

[0026] A toothed plate is provided at the bottom of the second crossbeam, and the driving gear cooperates with the toothed plate.

[0027] Furthermore, a plurality of connecting members are provided between the upper frame and the lower frame;

[0028] The upper frame and the lower frame are connected via a connecting piece.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. In the present invention, the upper platform frame includes a second upright, a second crossbeam rotatably mounted at the lower end of the second upright, and a translation assembly mounted at the lower end of the second crossbeam. The translation assembly drives the second crossbeam to move. By rotating the second upright, the upper end of the first mounting formwork is first separated from the wall. The translation assembly then drives the second crossbeam to move, freeing the entire first mounting formwork from the wall. This step-by-step demolding mechanism and the combined rotational and translational drive structure significantly optimize the demolding performance of the hydraulic self-climbing formwork system.

[0031] 2. In this invention, the upper end of the first mounting formwork is preferentially separated from the wall by rotating the second vertical rod, reducing the contact area between the formwork and the concrete from the entire surface to a localized area (e.g., the lower end). This directly weakens the normal adsorption force and frictional resistance between the formwork and the wall. Subsequently, the second horizontal beam is driven horizontally by a translation assembly, allowing the formwork to be completely separated in stages. This avoids the high-load conditions of traditional solutions that require overcoming resistance across the entire contact surface at once, significantly reducing the load on the drive system.

[0032] 3. In the present invention, when the upper end of the formwork rotates and detaches, the direction of the force is at an angle to the wall surface (not the traditional horizontal drag), which reduces the shear stress on the concrete surface; and the step-by-step detachment process avoids the rigid friction between the formwork and the wall surface, eliminates the risk of surface peeling or scratching, and improves the surface qualification rate of the wall.

[0033] 4. In the present invention, the translation assembly only needs to bear the residual resistance after the step-by-step disengagement, completely avoiding the high-torque engagement risk of the gear rack system, greatly reducing the equipment failure rate, and thus effectively extending the equipment maintenance cycle.

DETAILED DESCRIPTION

[0044] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0045] like Figures 1 to 8 As shown, the present invention provides a truss type hydraulic self-climbing formwork, which is arranged outside the wall 100 and includes an upper frame 1 and a lower frame 2 arranged below the upper frame 1;

[0046] The lower frame 2 includes a guide rail 3, a side frame 4 connected to the guide rail 3, and a climbing formwork cylinder assembly 6 provided on the side frame 4. The side frame 4 includes a lower platform frame 41 and a load-bearing tripod 42 provided on the top of the lower platform frame 41.

[0047] Two wall-mounted mounts 5 are provided on the guide rail 3 and are fixed to the outside of the wall 100;

[0048] The upper frame 1 includes a top platform 11 and a template frame 12 provided below the top platform 11. The template frame 12 includes a first mounting template 13 and an upper platform frame 14 provided on the side of the first mounting template 13. The upper platform frame 14 includes a second vertical rod 15, a second crossbeam 16 rotatably provided at the lower end of the second vertical rod 15, and a translation assembly 17 provided at the lower end of the second crossbeam 16. The translation assembly 17 is used to drive the second crossbeam 16 to move.

[0049] In the present invention, the truss-type hydraulic self-climbing formwork is arranged on the outside of the wall 100, and an internal formwork (i.e., a second installation formwork 101) is also arranged on the inside of the wall 100. The internal formwork works in conjunction with the first installation formwork 13 to ensure the double-sided forming accuracy of the concrete;

[0050] The climbing formwork cylinder assembly 6 includes a hydraulic cylinder and an upper and lower reversing box. The reversing box can control the lifting of the guide rail or the lifting frame. The climbing formwork cylinder assembly 6 can form a mutual climbing between the formwork frame and the guide rail, so that the hydraulic self-climbing formwork can climb steadily upward;

[0051] In addition, the truss-type hydraulic self-climbing formwork consists of an upper frame 1 and a lower frame 2, which are connected by a connector. Specifically, the upper frame 1 and the lower frame 2 are detachably connected by the connector. With this design, the on-site assembly and subsequent overall disassembly of the upper frame 1 and the lower frame 2 are simpler and faster, significantly improving construction efficiency and shortening the preparation time for the climbing formwork system to be put into use and the project completion time.

[0052] The lower frame 2 is composed of a guide rail 3, a side frame 4 and a climbing formwork cylinder assembly 6, while the side frame 4 is composed of a lower platform frame 41 and a load-bearing tripod 42. The structural design of the lower frame 2 is provided with an independent guide rail 3, which is specifically used to guide the climbing formwork system to climb vertically along the building structure accurately and stably. The guide rail 3 can be fixed to the outside of the wall 100 by using a wall-mounted mount 5. In the lower frame 2, the load-bearing tripod 42 serves as a rigid skeleton, providing strong bending, shear and torsion resistance, and can effectively withstand the construction load (personnel, materials, equipment) from the upper frame 1 and the deadweight of the climbing formwork system. Its triangular structure has natural geometric stability, which greatly enhances the structural rigidity and overall stability of the entire lower frame 2 and resists external force disturbances (such as wind loads and concrete lateral pressure) during construction. In addition, the load is transferred to the platform frame 41 through the load-bearing tripod 42, and then efficiently transferred to the main structure of the building through the anchor points on the tripod 42. The path is clear and direct, reducing the risk of stress concentration.

[0053] In the lower frame 2, the lower platform frame 41 is designed to provide a spacious, flat, and safe working surface, facilitating workers' core processes such as formwork operation, steel bar binding, and concrete pouring. Its location close to the working surface improves work efficiency. The separation of the working platform (lower platform frame 41) from the main load-bearing structure (load-bearing tripod 42) avoids the impact of platform deformation on the load-bearing structure, makes the platform layout more flexible, and facilitates independent maintenance or replacement of the platform.

[0054] Two wall-mounted mounts 5 are provided on the guide rail 3. The wall-mounted mounts 5 are fixedly arranged on the outside of the wall 100. The wall-mounted mounts 5 are provided to fix the guide rail 3 on the outside of the wall 100, that is, the guide rail 3 is installed on the wall-mounted mounts 5;

[0055] The upper frame 1 is composed of a top platform 11 and a template frame 12. The top platform 11 is arranged above the template frame 12, and the template frame 12 is composed of a first mounting template 13 and an upper platform frame 14. The first mounting template 13 is close to the outside of the wall 100, and the upper platform frame 14 is arranged on a side of the first mounting template 13 away from the wall 100, and the upper platform frame 14 is arranged on the top of the load-bearing tripod 42.

[0056] In addition, in the upper frame 1, the upper platform frame 14 is composed of a second vertical pole 15, a second horizontal beam 16 and a translation assembly 17, and the translation assembly 17 is used to drive the second horizontal beam 16 to move. From this structure, since the second horizontal beam 16 is rotatably provided at the lower end of the second vertical pole 15, during the demolding process (that is, the process of the first installation template 13 being separated from the wall 100), the second vertical pole 15 can be rotated to make the upper end of the first installation template 13 first separate from the wall 100, and then the translation assembly 17 can be used to drive the second horizontal beam 16 to move, so that the first installation template 13 is separated from the wall 100 as a whole, and the demolding is completed; this method avoids the high-load working condition of the traditional solution that needs to overcome the resistance of the entire contact surface at one time, and the load of the drive system is greatly reduced.

[0057] like Figures 1 to 8 As shown, in some embodiments of the present invention, an embedded part 51 is provided on the wall-mounted mount 5, and the wall-mounted mount 5 is fixed to the wall 100 through the embedded part 51;

[0058] The embedded part 51 includes an embedded plate 52, a high-strength screw 53 provided on the embedded plate 52, a climbing cone 54 provided on the outside of the high-strength screw 53, and a load-bearing bolt 55. The embedded plate 52, the high-strength screw 53, and the climbing cone 54 are all provided in the wall 100.

[0059] A threaded mounting hole 1 is provided at one end of the climbing cone 54 away from the high-strength screw 53 and is matched with the stressed bolt 55;

[0060] The wall mount 5 is provided with a threaded mounting hole 2 that matches the force bolt 55. The force bolt 55 passes through the threaded mounting hole 2 and is tightened in the threaded mounting hole 1.

[0061] An embedded part 51 is provided on the wall mount 5, and the embedded part 51 is set in the wall 100, so that the wall mount 5 can be fixed to the outside of the wall 100. The wall mount 5 is used for installing the guide rail 3;

[0062] The embedded component 51 is composed of an embedded plate 52, a high-strength screw 53, a climbing cone 54, and a load-bearing bolt 55. The embedded plate 52, high-strength screw 53, and climbing cone 54 are all pre-buried within the concrete of the wall 100, forming a tight anchor with the concrete. The climbing cone 54 effectively improves the screw's pullout resistance. Combined with the high strength of the high-strength screw 53, the entire embedded component system 51 has an extremely high load-bearing capacity and stability, providing a solid support foundation for the wall mount 5 and the guide rail 3 it supports.

[0063] In addition, the embedded parts 51 are pre-buried in place when the wall 100 is poured. When the wall-mounted mount 5 is installed later, it only needs to be connected and fixed through the pre-buried high-strength screws 53. This design eliminates the complicated processes of drilling holes and planting steel bars on the hardened wall, significantly simplifies the installation process, improves construction efficiency, and helps to ensure the installation position accuracy of the wall-mounted mount 5; the core load-bearing components of the embedded system 51 are deeply buried in the concrete, and the force transmission path is clear (wall-mounted mount → load-bearing bolts → high-strength screws → climbing cones / embedded plates → concrete wall), and the overall structure is stable. The bite effect of the climbing cone 54 and the concrete can effectively resist vibration, impact or cyclic loads, has excellent fatigue resistance, and ensures the stability and safety of the long-term operation of the guide rail 3;

[0064] The wall mount 5 is connected to the pre-buried high-strength screw 53 via a load-bearing bolt 55. This connection is not only secure and reliable, but also relatively easy to disassemble and re-tighten when necessary (such as for fine-tuning the position or maintenance and replacement), increasing its flexibility. The main anchoring points (embedded plate, screw, climbing cone) are all located inside the wall, with only the nut of the load-bearing bolt 55 and the wall mount 5 itself located outside the wall 100. This design minimizes damage to the existing wall surface (such as large-scale grooving and dense drilling), maintains the integrity of the wall surface, and reduces the risk of water seepage caused by later drilling.

[0065] This solution embeds key anchoring components (embedded plates, high-strength screws, and climbing cones) in the wall and uses load-bearing bolts for external connection, achieving a secure, convenient, and precise installation of the wall mount 5. This provides a high-load-bearing, highly stable, and long-life support foundation for the guide rail 3, while simplifying construction and protecting the wall structure.

[0066] In addition, an embedded part 51 is also provided at one end of the wall 100 close to the first installation template 13 for fixing the first installation template 13 .

[0067] like Figures 1 to 8 As shown, in some embodiments of the present invention, the load-bearing tripod 42 includes a first crossbeam 421, a first vertical rod 422 provided at the lower left end of the first crossbeam 421, and a first diagonal brace 423. The first crossbeam 421 and the first vertical rod 422 are connected in an L-shape, and the two ends of the first diagonal brace 423 are respectively connected to the first crossbeam 421 and the first vertical rod 422.

[0068] Specifically, the left end of the bottom of the first crossbeam 421 is connected to the top of the first vertical pole 422. In addition, the first crossbeam 421 and the first vertical pole 422 are connected in a detachable manner, which can be a bolt connection.

[0069] Both ends of the first diagonal brace 423 are connected to the first crossbeam 421 and the first vertical rod 422 respectively, so that a triangular structure is formed among the first diagonal brace 423 , the first crossbeam 421 and the first vertical rod 422 , further enhancing the stability of the load-bearing tripod 42 .

[0070] like Figures 1 to 8 As shown, in some embodiments of the present invention, a beam hook 424 is provided at the left end of the first vertical rod 422; the beam hook 424 is provided on the wall-mounted hanging seat 5;

[0071] The end of the crossbeam hook 424 away from the first vertical rod 422 is integrally formed with a hook, which can be hung on the wall hanging seat 5 and initially fixed to the wall hanging seat 5; in addition, after the side frame 4 is hung on the wall hanging seat 5 through the crossbeam hook 424, the connection can be provided with a through hole for inserting a safety pin. By inserting the safety pin, the crossbeam hook 424 and the wall hanging seat 5 are connected and fixed. During the climbing process, the connection between the crossbeam hook 424 and the wall hanging seat 5 can be released by removing the safety pin.

[0072] In addition, a wall support 425 is provided on the side of the first vertical pole 422; the wall support 425 is used to fix the first vertical pole 422 to the outside of the wall 100, and combined with the wall mount 5, complete the fixation of the load-bearing tripod 42; prevent it from shaking during the actual construction process and ensure its stability.

[0073] like Figures 1 to 8 As shown, in some embodiments of the present invention, a second installation template 101 is provided on the inner side of the wall 100;

[0074] A plurality of tension screws 102 are provided in the wall 100. Both ends of each tension screw 102 are provided with screw mounting members 103. The two screw mounting members 103 are respectively provided on the first mounting template 13 and the second mounting template 101.

[0075] The formwork on wall 100 is tensioned using D20 high-strength screws (i.e., tensioning screws 102). The tensile strength of the tensioning screws is 255 kN, and the horizontal spacing between them does not exceed 1200 mm. Four tensioning screws 102 can be arranged vertically. The tensioning screws 102 are secured using D20 butterfly nuts and washers. The tensioning screws 102 can be arranged in either solid or standard positions. Solid tension is preferred, with the solid position being permanently embedded in the concrete.

[0076] like Figures 1 to 8 As shown, in some embodiments of the present invention, a second diagonal brace 18 is provided on one end of the second crossbeam 16 away from the second vertical rod 15 , and the second diagonal brace 18 is rotatably provided on the second crossbeam 16 ;

[0077] One end of the second diagonal brace 18 away from the second crossbeam 16 is rotatably mounted on the second vertical rod 15;

[0078] Specifically, the second diagonal support 18 can be a hydraulic rod or a cylinder. In actual operation, the second vertical pole 15 is rotated by opening and closing the second diagonal support 18, and the rotation angle is adjustable.

[0079] The translation assembly 17 includes a translation guide rail 171, a drive mechanism, and a driving gear 172. The drive mechanism is used to drive the driving gear 172 to rotate. The second crossbeam 16 is slidably mounted on the translation guide rail 171. A toothed plate 161 is provided at the bottom of the second crossbeam 16, and the driving gear 172 cooperates with the toothed plate 161.

[0080] More specifically, the process of the rotation adjustment is as follows:

[0081] Step 1: A driving member is provided on the second crossbeam 16, and the driving member may be a cylinder or a hydraulic rod;

[0082] The output end of the driving member is provided with an inverted U-shaped member, and the non-toothed area of ​​the tooth plate 161 is provided in the open end of the inverted U-shaped member and can slide left and right in the open end of the inverted U-shaped member;

[0083] Step 2: Activate the driving member to extend or retract the tooth plate 161 so that the tooth plate 161 is disengaged from the driving gear 172, and activate the second diagonal brace 18, which drives the second vertical rod 15 to rotate a certain angle (the rotation angle is generally less than 15 degrees), so that the upper end of the first installation template 13 is separated from the wall 100;

[0084] Step 3: Start the driving member again to make the tooth plate 161 move in the opposite direction, so that the tooth plate 161 engages with the driving gear 172, and then start the driving mechanism to rotate the driving gear 172, driving the tooth plate 161 to move right, so that the first installation template 13 is completely separated from the wall 100.

[0085] like Figures 1 to 8 As shown, in some embodiments of the present invention, a plurality of connectors 7 are provided between the upper frame 1 and the lower frame 2; the upper frame 1 and the lower frame 2 are connected by the connectors 7;

[0086] In addition, the upper frame 1 and the lower frame 2 are both fixed to the connecting member 7 by bolt connection. Specifically, the upper frame 1 is fixed to the top of the connecting member 7 by bolt connection, and the lower frame 2 is fixed to the bottom of the connecting member 7 by bolt connection.

[0087] Specifically, during the actual construction process, the truss-type hydraulic self-climbing formwork is set outside the wall 100, and the installation process is as follows:

[0088] Step 1: Concrete pouring is completed → remove the formwork and move it back → tie the steel bars → install the wall mounting device (wall mounting bracket 5) → lift the guide rail 3 → climb the frame → clean the formwork and apply release agent → fix the embedded parts on the formwork → close the formwork → pour concrete.

[0089] Step 2: Install the embedded parts (embedded part 51). Secure the climbing cone 54 to the first mounting template 13 with load-bearing bolts 55. Grease the hole in the climbing cone 54 and tighten the high-strength screw 53 to prevent concrete from flowing into the threads of the climbing cone 54. Screw the embedded plate onto the other end of the high-strength screw. The cone faces the template, in the opposite direction from the climbing cone.

[0090] Step 3: If there is a conflict between the embedded parts and the steel bars, the steel bars should be appropriately shifted before closing the mold.

[0091] Step 4: Lift the guide rail and adjust the reversing devices in the upper and lower reversing boxes to face upward simultaneously. The upper end of the reversing devices should support the guide rail.

[0092] Step 5: When climbing the frame, adjust the upper and lower reversing boxes to the downward direction at the same time, with the lower end supporting the guide rail. (During the climbing or lifting of the guide rail, the hydraulic control console can be controlled. The hydraulic control console adopts a conventional control console. In the actual construction process, the hydraulic control console is operated by a dedicated person. Each frame is assigned a dedicated person to monitor whether it is synchronized. If it is found to be out of sync, the hydraulic valve control can be adjusted.)

[0093] Step 6: After the guide rail is lifted into place, remove the lower wall attachment device and climbing cone and use them in rotation. Note: A total of three sets of wall attachment devices and climbing cones can be installed, of which two sets are pressed under the guide rail and one set is in rotation.

[0094] The present invention provides a truss-type hydraulic self-climbing formwork. The upper platform frame 14 includes a second upright 15, a second crossbeam 16 rotatably mounted at the lower end of the second upright 15, and a translation assembly 17 mounted at the lower end of the second crossbeam 16. The translation assembly 17 is used to drive the movement of the second crossbeam 16. By rotating the second upright 15, the upper end of the first installation formwork 13 is first separated from the wall 100. The translation assembly 17 then drives the movement of the second crossbeam 16, allowing the entire first installation formwork 13 to be separated from the wall 100. The use of a step-by-step demolding mechanism and a rotatable and translational composite drive structure significantly optimizes the demolding performance of the hydraulic self-climbing formwork system.

[0095] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
