Description

Technical Field

[0001] This utility model relates to the field of climbing formwork equipment technology, and in particular to a hydraulic climbing formwork device. Background Technology

[0002] Climbing formwork is an advanced formwork technology suitable for the construction of cast-in-place reinforced concrete vertical structures in high-rise buildings or tall structures. Climbing formwork is attached to the building structure and rises layer by layer as the structure is constructed. Once the concrete reaches its demolding strength, the formwork does not touch the ground; instead, mechanical equipment and supports propel the formwork and climbing device upwards one layer, where it is positioned and secured, and this process is repeated.

[0003] Existing climbing formwork equipment is often as shown in the "Hydraulic Climbing Formwork" disclosed in patent number CN102704675A, which includes: a formwork frame, the lower part of which is connected to the wall by bolts, the upper part of which is provided with longitudinal guide rails, an outer frame, and a crossbeam fixed to the upper end of the guide rails and the outer frame; a steel formwork, the back of which is provided with multiple transverse reinforcing wings, each reinforcing wing having a through hole that fits onto the guide rail, a through-hole jack on the top reinforcing wing of the steel formwork, and a hoist on the reinforcing wing in the middle of the steel formwork, the cable of which is connected to the lower end of the formwork frame.

[0004] In actual operation, the steel formwork in the aforementioned patent moves upward along the guide rail. Most existing patents also operate similarly, with the steel formwork moving up and down under the influence of a through-hole jack.

[0005] However, during actual demolding, demolding, and vertical movement, horizontal movement of the steel formwork is unavoidable. Existing hydraulic climbing formwork devices cannot achieve this horizontal movement.

[0006] Therefore, there is an urgent need in this field for a new type of hydraulic climbing formwork device to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a hydraulic climbing formwork device to solve the problems existing in the prior art, which can drive the formwork body to move horizontally as needed.

[0008] To achieve the above objectives, this utility model provides the following solution:

[0009] This utility model discloses a hydraulic climbing formwork device, comprising:

[0010] A climbing formwork jack, wherein the climbing formwork jack is mounted on a support rod, and the support rod passes through the center of the climbing formwork jack;

[0011] Climbing formwork frame, with the climbing formwork jacks installed on the climbing formwork frame;

[0012] A translation trolley is rotatably mounted on the climbing formwork frame. The translation trolley can move horizontally on the climbing formwork frame and is connected to the template body.

[0018] Preferably, a wheel is provided at each of the four lower corners of the translation trolley, and two parallel limiting guide rails are provided on the climbing formwork frame. The wheels on both sides of the translation trolley are located on the outside of the two limiting guide rails.

[0019] Preferably, the lower end of the climbing formwork jack is fixed to the climbing formwork frame by bolts.

[0020] Preferably, the translation trolley is connected to a pushing device, which is used to push the translation trolley to move.

[0021] Preferably, the pushing device includes a fixed base and a pushing hydraulic cylinder. The fixed base is fixed to the climbing formwork frame, one end of the pushing hydraulic cylinder is fixed to the fixed base, and the other end of the pushing hydraulic cylinder is connected to the translation trolley.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this invention is to provide a hydraulic climbing formwork device to solve the problems existing in the prior art, which can drive the formwork body to move horizontally as needed.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figures 1-2 As shown, this embodiment provides a hydraulic climbing formwork device, including:

[0033] Climbing formwork jack 3 is installed on support rod 2, and support rod 2 passes through the center of climbing formwork jack 3.

[0034] The fixed end of the climbing formwork frame 1 and the climbing formwork jack 3 are installed on the upper surface of the end of the climbing formwork frame 1. It should be noted here that... Figure 1 The climbing formwork 1 shown is only the end position. The complete climbing formwork 1 may be a grid-like structure with intersecting horizontal and vertical lines or other shapes. Depending on the construction, the specific shape of the climbing formwork 1 will also be different. Therefore, the end of the climbing formwork 1 and the number of climbing formwork jacks 3 fixed on the end will also be different. So, it is not limited here.

[0035] The translation trolley 4 is rotatably mounted at the end of the climbing formwork frame 1, and can move horizontally on the climbing formwork frame 1. Furthermore, the template body 6 is fixedly connected to the lower part of the translation trolley 4, so when the translation trolley 4 moves, it also drives the template body 6 to move synchronously.

[0036] In practical use, after the lower construction is completed, the tractor 4 is driven to move outward (towards the side away from construction) to perform demolding. Then, the climbing formwork hydraulic cylinder is activated, which drives the climbing formwork frame 1 and all its components to move upward together. Once it reaches the appropriate position, the tractor 4 is driven to move inward (towards the side closer to construction) to install the formwork body 6. The entire device has a simple structure, is easy to operate, and provides certain conveniences for construction.

[0037] In this embodiment, the climbing formwork jack 3 is a through-hole jack (or hollow jack), which is a common type of hydraulic jack used in climbing formwork or slipform construction. When it is in operation, high-pressure oil needs to be introduced into it to lock the upper clamping head and support rod 2, lifting the cylinder and lower clamping head (thus driving the climbing formwork frame 1 and its components upwards). Then, the lower clamping head is locked back into the support rod 2, and the oil return releases the upper clamping head. The piston and upper clamping head are then lifted and reset under the action of the spring, thus completing one lifting operation. Since the climbing formwork jack 3 is existing equipment, and its working principle is common knowledge in the field, its internal structure and connections will not be further described here.

[0038] In this embodiment, due to the limitations of the construction environment, the translation trolley 4 is not directly fixedly connected to the template body 6. Instead, the translation trolley 4 is fixedly connected to the upper end of the template body 6 through a connector 5.

[0039] In this embodiment, the connector 5 is a threaded steel bar. The upper end of the threaded steel bar is fixedly connected to the translation trolley 4, and the lower end of the threaded bar can be welded to the template body 6 or fixedly connected by a nut.

[0040] In other embodiments, those skilled in the art can also use other types of rods to achieve a fixed connection between the translation trolley 4 and the template body 6.

[0041] In this embodiment, a fixing nut is threaded onto the threaded steel bar. The translation trolley 4 has a central hole through which the threaded steel bar passes. The fixing nut is located on the upper surface of the translation trolley 4, and its diameter is larger than the diameter of the central hole, so the fixing nut will not pass through the central hole. In actual use, the threaded steel bar will move downwards due to its own weight and the weight of the template body 6. Since the size of the fixing nut is larger than the size of the central block, the translation trolley 4 can support the fixing nut and the threaded steel bar connected to it.

[0042] In this embodiment, the template body 6 can be a conventional steel template. This structure is a commonly used template for pouring construction. The specific shape and size of the steel template will vary depending on the construction method, so it is not limited here.

[0043] In this embodiment, as Figure 2 As shown, a wheel is located at each of the four corners of the lower end of the translation trolley 4. The climbing formwork frame 1 has two parallel limiting guide rails 101. The end of the climbing formwork frame 1 is composed of two parallel crossbeams, each crossbeam having a raised limiting guide rail 101. The wheels on both sides of the translation trolley 4 are located outside the two limiting guide rails 101, respectively. Figure 2 To illustrate with a directional perspective, the front and rear wheels on the left side of the translating trolley 4 are located at the left end of the left-side limiting guide rail 101, and the front and rear wheels on the right side of the translating trolley 4 are located at the right end of the right-side limiting guide rail 101. This arrangement is intended to limit the movement of the translating trolley 4, ensuring it can only move linearly along the length of the limiting guide rail 101 and preventing lateral deviation.

[0044] In this embodiment, the lower end of the climbing formwork jack 3 (i.e., the lower end of the cylinder of the climbing formwork jack 3) is fixed to the climbing formwork frame 1 by bolts, thereby fixing the climbing formwork jack 3 to the climbing formwork frame 1 and facilitating disassembly.

[0045] In this embodiment, the translation trolley 4 is connected to a pushing device 7, which is used to push the translation trolley 4 to move.

[0046] In other embodiments, the pushing device 7 may not be provided, and workers may use tools to push the translation trolley 4.

[0047] In this embodiment, the pushing device 7 includes a fixed base 701 and a pushing hydraulic cylinder 702. The fixed base 701 can be fixed to the climbing formwork frame 1 by welding or bolts. One end (cylinder body part) of the pushing hydraulic cylinder 702 is fixed to the fixed base 701 by bolts, and the other end of the pushing hydraulic cylinder 702 is connected to the translation trolley 4.

[0048] A conventional hydraulic cylinder can be used to drive the hydraulic cylinder 702. In actual use, the reciprocating movement of the translation trolley 4 is achieved by controlling the extension and retraction of the hydraulic cylinder 702.

[0049] Example 2

[0050] This embodiment provides a method for operating a hydraulic climbing formwork device, including the following steps:

[0051] Step 1: When the construction below is completed and climbing formwork is required, first control the hydraulic cylinder 702 to retract, so that it pulls the translation trolley 4 and the formwork body 6 outward to carry out the demolding work.

[0052] Step 2: Start the climbing formwork jack 3, which will drive the climbing formwork frame 1 and all the components on the climbing formwork frame 1 to move upward synchronously.

[0053] Step 3: After reaching the expected position, control the extension of the hydraulic cylinder 702, thereby driving the translation trolley 4 and the template body 6 to move inward, install the template body 6, and prepare for construction.
