Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a hydraulic climbing formwork for super high-rise buildings. Background Technology

[0002] Hydraulic climbing formwork uses hydraulic jacks or hydraulic cylinders as power devices. The lifting climbing formwork is used for pouring concrete piles. When pouring concrete piles for ultra-high-rise buildings, the height and risk factor are high. A common lifting method is to move and fix the formwork on fixed rails on the concrete pile. However, if not operated properly, the climbing formwork is prone to collapse.

[0003] Patent CN111236630B discloses an automatic hydraulic climbing formwork, including a template. The outer wall of the template has a guide rail, and fixing plates are fixedly connected to both ends of the guide rail and the outer wall of the template. A slider slides on the guide rail, and a clamping mechanism is provided between the slider and the template. A hydraulic cylinder is fixed on the slider, with its drive end vertically upward. A lifting frame also slides on the guide rail, and a vertical plate is fixed to the end of the lifting frame. A limiting mechanism is provided between the vertical plate and the template. A winding reel is fixed to the upper outer wall of the template via a connecting rod, and a bearing is fixedly embedded in the winding reel. A rotating rod is inserted into the bearing. While this patent solves the fixing problem, the ratchet and pawl method results in a small contact area, increasing the pressure on individual contact points and raising the risk of damage. Furthermore, the method of fixing via an external sliding rail on the cast-in-place structure increases the risk of insecure installation.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0006] A hydraulic climbing formwork for super high-rise buildings includes a climbing frame. From top to bottom, the bottom of the climbing frame is provided with a bottom support, a pushing block, and an extrusion plate.

A spring is provided on the outer side of each limiting post, with one side abutting against the bottom support and the other side abutting against the bottom of the climbing frame. Multiple sets of hydraulic devices are fixedly connected in the middle of the bottom support. The upper extension of each hydraulic device is fixedly connected to the rod limiters at the bottom of the climbing frame. A latch is fixedly connected to the bottom support on one side of the hydraulic device. A through hole is opened on the bottom support at the bottom of the sling on one side of the latch. A second sling is fixedly connected to the bottom support on one side of the through hole, and a pulley is rotatably connected to the middle of the second sling.

[0007] Preferably, the upper part of the push block is fixedly connected to an elastic fixing mechanism, the elastic fixing mechanism including a telescopic column fixedly connected to the bottom extension end of the hydraulic device, the telescopic column is provided with grooves on both sides, the grooves are provided with round holes, and springs are fixedly connected inside the round holes. Each groove is rotatably connected to an outer top plate, one side of the outer top plate is provided with a sliding groove, the other side of the outer top plate is provided with an inclined groove, the bottom of the groove is rotatably connected to an inner top plate, one side of the inner top plate is slidably connected to the sliding groove on one side of the outer top plate, and one side of springs abuts against the inner top plate.

[0008] Preferably, the push block has a semi-circular groove inside, a fixed column is provided in the middle of the semi-circular groove, a top plate mechanism is rotatably connected to the fixed column, an installation plate is fixedly connected to one side of the push block, and a bolt is fixedly connected to one side of the installation plate, and the bolt is fixedly connected to the push block.

[0009] Preferably, the top plate mechanism includes a support plate, one side of which has a hole for rotatable connection with a fixed column, and the other side of which has a rotating column. The rotating column has top blocks on both sides that are fixedly connected to the support plate.

[0010] Preferably, one side of the extrusion plate is fixedly connected with multiple sets of protrusions, the other side of the extrusion plate is provided with multiple sets of limiting holes that are rotatably connected to the rotating column, and the top of the extrusion plate is fixedly connected with a locking buckle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention adds a bottom support, a pushing block, and a pressing plate to the base of the original climbing frame. When the ratchet and pawl mechanisms on the original climbing frame, which are used for climbing and fixing, fail, the climbing frame moves downwards. The bottom support and the climbing frame expand to both sides under the action of spring one. The ropes connected to the bottom support and the pressing plate pull the pressing plate to tilt, and the bottom of the pressing plate presses against the poured material. The friction between the pressing plate and the poured material increases, and the climbing frame moves downwards under the action of inertia, pressing against the bottom support. The hydraulic device pushes the pressing plate, pressing the protrusion at the front end of the pressing plate against the poured material. The elastic fixing mechanism moves out of the hydraulic device, and the inner top plate pushes the outer top plate to unfold under the action of spring two. The outer top plate has a groove on its outer side to lock the bottom of the hydraulic device in place, preventing the elastic fixing mechanism from retracting when stationary. Multiple units of this invention surround the poured material and are used in combination to stably fix the climbing frame to the poured material, making it safer and more reliable.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 9As shown, a hydraulic climbing formwork for high-rise buildings can be used for concrete pouring and molding operations. It includes a climbing frame 2. From top to bottom, the bottom of the climbing frame 2 is provided with a bottom support 3, a pushing block 4, and an extrusion plate 5. Four through holes 201 are provided around one side of the bottom of the climbing frame 2. Multiple rod limiters 202 are located in the middle of the bottom of the climbing frame 2. A sling 203 is fixedly connected to one side of the rod limiter 202 and is rotatably connected to a pulley 7. Limiting posts 301 are fixedly connected around the upper part of the bottom support 3. The limiting posts 301 are slidably connected to the through holes 201 on the climbing frame 2. A spring 302 is provided on the outer side of the limiting post 301, and one side of the spring 302 abuts against the bottom support 3. The spring 302 is in a compressed state. A suitable spring 302 is selected according to the size of the climbing frame so that the spring 302 can support the weight of the climbing frame 2 and the personnel and other items on it. The other side of spring 302 abuts against the bottom of the climbing frame 2. Multiple sets of hydraulic devices 303 are fixedly connected in the middle of the bottom support 3. The number of hydraulic devices 303 depends on the size of the upper climbing frame 2. When the climbing frame 2 is too large, multiple sets of hydraulic devices 303 can be set to share the load. The upper protruding end of the hydraulic device 303 is fixedly connected to the rod limit 202 at the bottom of the climbing frame 2. A locking buckle 304 is fixedly connected to the bottom support 3 on one side of the hydraulic device 303. A through hole 305 is opened on the bottom support 3 at the bottom of the sling 203 on one side of the locking buckle 304. A sling 2 306 is fixedly connected to the bottom support 3 on one side of the bottom of the through hole 305. A pulley 7 is rotatably connected in the middle of the sling 2 306.

[0029] The upper part of the push block 4 is fixedly connected to an elastic fixing mechanism 401. The elastic fixing mechanism 401 includes a telescopic column 401A fixedly connected to the bottom protruding end of the hydraulic device 303. The telescopic column 401A has grooves on both sides, and a round hole is opened in the groove. A spring 401D is fixedly connected in the round hole. An outer top plate 401B is rotatably connected to the upper part of each groove. A sliding groove is provided on one side of the outer top plate 401B, and an inclined groove is provided on the other side of the outer top plate 401B. An inner top plate 401C is rotatably connected to the bottom of the groove. One side of the inner top plate 401C is slidably connected to the sliding groove on one side of the outer top plate 401B. One side of the spring 401D abuts against the inner top plate 401C. When the inner top plate 401C and the outer top plate 401B are folded, they can be completely inserted into the groove inside the telescopic column 401A. Of course, the elastic fixing mechanism 401 after folding can also be inserted into the hydraulic device 303.

[0030] The push block 4 has a semi-circular groove inside, which limits the top plate mechanism 403 to rotate only within a range of 190° to 220°, thus transferring most of the force during the descent of the climbing frame 2 to the pressing plate 5. A fixing column 402 is located in the middle of the semi-circular groove to limit the rotation of the top plate mechanism 403. The top plate mechanism 403 is rotatably connected to the fixing column 402. A mounting plate 404 is fixedly connected to one side of the push block 4 to secure the top plate mechanism 403 inside the push block 4. Bolts 405 are fixedly connected to one side of the mounting plate 404, facilitating the disassembly, installation, and maintenance of the top plate mechanism 403. The top plate mechanism 403 includes a support plate 403B. One side of the support plate 403B is provided with a hole 403A that is rotatably connected to the fixed column 402. The other side of the support plate 403B is provided with a rotating column 403C. The rotating column 403C is rotatably connected to the extrusion plate 5. The rotating column 403C is provided with top blocks 403D on both sides that are fixedly connected to the support plate 403B. The function of the top blocks 403D is to limit the extrusion plate 5 and prevent the extrusion plate 5 from rubbing against the slab 1 when the climbing frame 2 is working normally. In case of an accident, the rope 6 can pull the extrusion plate 5 to rotate.

[0031] Multiple sets of protrusions 503 are fixedly connected to one side of the extrusion plate 5, and multiple sets of limiting holes 501 are provided on the other side of the extrusion plate 5, which are rotatably connected to the rotating column 403C. A second locking buckle 502 is fixedly connected to the top of the extrusion plate 5. A rope 6 is fixedly connected to the second locking buckle 502. The rope 6 passes through the pulley 7 on the second sling 306, through the through hole 305, through the pulley 7 on the first sling 203, and is finally fixedly connected to the first locking buckle 304. The function of the pulley 7 is to reduce friction when the rope 6 slides, so as to facilitate the sliding of the rope 6. The expansion of the climbing frame 2 and the bottom support 3 causes the rope 6 to pull the extrusion plate 5 to tilt. A casting 1 is provided on one side of the climbing frame 2. A slide rail assembly 101 is fixedly connected to the casting 1. One side of the slide rail assembly 101 is fixedly connected to the climbing frame 2, and the slide rail assembly 101 is also fixedly connected to the bottom support 3. The slide rail assembly 101 is the existing technology on the existing hydraulic climbing formwork frame, which plays the role of moving and fixing the climbing frame 2 and the bottom support 3, and will not be described in detail. The side of the extrusion plate 5 with protrusions 503 faces the casting 1, which facilitates pushing the protrusions 503 into the casting 1, thereby slowing down the climbing frame 2. The extrusion plate 5 is parallel to the casting 1. When the extrusion plate 5 is not working, it is parallel to the casting 1 and does not contact it, which allows the climbing frame 2 to move up and down normally. However, when the climbing frame 2 falls abnormally, the extrusion plate 5 is tilted to the casting 1, which facilitates the extrusion plate 5 to contact the casting 1.

[0032] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0033] Working Principle: When this utility model is used to work around the casting 1, if the ratchet and pawl responsible for movement and fixation malfunction, the climbing frame 2 will fall. At this time, the climbing frame 2 will not generate a gravitational load on the bottom support 3 or the gravitational load will be reduced. The climbing frame 2 and the bottom support 3 will begin to expand under the action of spring 302. The rope 6 fixed to the locking buckle 304 of the bottom support 3 will be stretched, causing the extrusion plate 5 to tilt. The protrusion 503 on one side of the extrusion plate 5 will extrude the casting 1. The bottom support 3 will begin to decelerate. Under the action of inertia, the climbing frame 2 will press down on the bottom support 3. The protrusion 503 on the side of the extrusion plate 5 at the bottom of the bottom support 3, which is close to the casting 1, will push the casting 1 forward. The upper extension of the hydraulic device 303 fixed to the top support 3 is fixed to the climbing frame 2. The upper extension moves downward, pushing the elastic fixing mechanism 401 out of the hydraulic device 303. The inner top plate 401C in the telescopic column 401A will push the outer top plate 401B to unfold under the action of spring 401D. When the climbing frame 2 stops falling, the hydraulic device 303 prevents the elastic fixing mechanism 401 from retracting under the action of the spring 302, and the inclined groove on the outer side of the outer top plate 401B cooperates with the bottom of the hydraulic device 303 for fixation.

[0034] Because multiple of these inventions surround the building, the climbing frame 2 can be firmly fixed to the concrete 1 and will not move, thus increasing safety.

[0035] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
