Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a concrete formwork spacing adjustment device. Background Technology

[0002] Concrete formwork gaps refer to the spaces reserved between adjacent formworks or between formworks and supporting structures during concrete pouring. Their purpose is to prevent the formwork from being damaged by the concrete when it expands under pressure due to formwork deformation, thermal expansion and contraction, or construction errors, while ensuring that the concrete is compacted and formed.

[0003] Chinese patent document CN216266666U discloses "a concrete formwork gap adjustment device with a positioning structure, including connecting uprights, two sets of connecting uprights, a connecting shaft in the middle of one side of the connecting uprights, a rotating base at the lower end of the connecting uprights, and fixed crossbars movably connected to one side of the connecting uprights, several sets of fixed crossbars, the crossbars of which are I-shaped. Through the cooperation of the fixed crossbars and connecting uprights, the fixed crossbars are connected to the slots via clips, and then nuts are used to fix the fixed crossbars and connecting uprights together, forming a unified support frame. The I-shaped crossbar design of the fixed crossbars increases the contact area between the fixed crossbars and the formwork, reduces pressure, and enhances the reinforcement effect of the formwork, providing both horizontal and vertical reinforcement and improving the overall reinforcement effect." However, this concrete formwork gap adjustment device has the following drawbacks: (1) When applying pressure to the concrete formwork, the length of the connecting pole is fixed. Different lengths of connecting poles need to be replaced when facing concrete of different heights in order to apply pressure to the formwork as a whole. The construction is complicated and has poor adaptability. Furthermore, the use of multiple sets of connecting poles and fixed crossbars in a cross-connection manner can easily lead to uneven stress. (2) The surface of concrete formwork is generally a vertical plane. Applying pressure by rotating the adjusting screw can easily cause the concrete surface to tilt, resulting in poor construction effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a concrete formwork spacing adjustment device that is simple to construct, highly adaptable, ensures uniform stress on the formwork, and achieves good construction results.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A concrete formwork spacing adjustment device includes a top frame and two movable frames. The top ends of the two movable frames are slidably mounted on the top frame and arranged opposite each other. The top frame is provided with a telescopic drive mechanism on the outside of each movable frame. The telescopic drive mechanism is connected to the corresponding movable frame and is used to drive the two movable frames to move closer and further apart. The inner side of each movable frame is provided with a pressure plate. The bottom of the pressure plate is provided with a docking part for connecting with a heightening plate.

[0006] As a further improvement to the above technical solution: The top frame is provided with transverse guide columns on both sides, and each of the movable frames is slidably sleeved on the transverse guide columns.

[0007] Both ends of the transverse guide column are provided with mounting seats, which can be detachably installed on the top frame.

[0008] The telescopic drive mechanism includes a fixed base and a telescopic drive component. The fixed base is fixed on the top frame, and the telescopic drive component is installed on the fixed base and connected to the corresponding movable frame.

[0009] The telescopic drive component is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0010] The pressure plate is connected to an extension plate via a docking part.

[0011] The docking part is a slot extending along the length of the pressure plate, and the top of the heightening plate is provided with a locking block that mates with the slot.

[0012] The inner sides of both the pressure plate and the heightening plate are provided with anti-slip protrusions.

[0013] The outer side of the heightening plate is provided with a reinforcing force, which is detachably fixed to the movable frame by a fixing block.

[0014] The top frame is square, with an observation port in the middle and a handle at the top.

[0015] Compared with the prior art, the advantages of this utility model are: This utility model discloses a concrete formwork spacing adjustment device. During use, a suitable pressure plate is selected according to the specifications of the concrete formwork. The entire device is clamped on both sides of the concrete formwork, specifically the pressure plates on the inner sides of the two moving frames. Then, the telescopic drive mechanism on the outer side of the moving frames drives the two frames closer together, causing the pressure plates on the two frames to press towards the center, thus adjusting the spacing of the concrete formwork. If the concrete formwork is too high, an extension plate can be connected through the joint to apply pressure to concrete formwork of different heights. This concrete formwork spacing adjustment device offers several advantages. First, it allows for pressure application to concrete formwork of different heights through the connection of the extension plate, simplifying construction and offering strong adaptability. Furthermore, the telescopic drive mechanism ensures even pressure distribution on the formwork, preventing uneven stress. Second, the pressure plates move horizontally with the moving frames, reducing the risk of concrete surface tilting and resulting in better construction performance. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1: Figure 1 and Figure 2 An embodiment of the concrete formwork spacing adjustment device of this utility model is shown. The concrete formwork spacing adjustment device of this embodiment includes a top frame 1 and two movable frames 2. The top ends of the two movable frames 2 are slidably mounted on the top frame 1 and arranged opposite to each other. The top frame 1 is provided with a telescopic drive mechanism 3 on the outside of each movable frame 2. The telescopic drive mechanism 3 is connected to the corresponding movable frame 2 and is used to drive the two movable frames 2 to move closer and further away. The inner side of each movable frame 2 is provided with a pressure plate 4. The bottom of the pressure plate 4 is provided with a docking part 41 for docking with the heightening plate 5.

[0025] During use, a suitable pressure plate 4 is selected according to the specifications of the concrete formwork. The entire device is clamped on both sides of the concrete formwork, i.e., the pressure plates 4 on the inner sides of the two moving frames 2 are clamped on both sides of the concrete formwork. Then, the telescopic drive mechanism 3 on the outer side of the moving frames 2 drives the two moving frames 2 to move closer together, causing the pressure plates 4 on the two moving frames 2 to press towards the middle, thereby adjusting the gap of the concrete formwork. At the same time, if the concrete formwork is too high, the extension plate 5 can be connected through the docking part 41 to apply pressure to concrete formwork of different heights. This concrete formwork spacing adjustment device has several advantages. First, it can apply pressure to concrete formwork of different heights by connecting the extension plate 5 through the docking part 41. It is simple to construct and highly adaptable. Furthermore, the telescopic drive mechanism 3 drives the two moving frames 2 to move closer together to apply pressure, ensuring that the formwork is subjected to uniform force and preventing uneven force distribution. Second, the pressure plate 4 moves horizontally with the moving frames 2, preventing the concrete surface from tilting and resulting in good construction effect.

[0026] Furthermore, in this embodiment, transverse guide posts 6 are provided on both sides of the top frame 1, and each movable frame 2 is slidably sleeved on the transverse guide posts 6. The movable frame 2 translates along the transverse guide posts 6, and the movement stability is good.

[0027] Furthermore, in this embodiment, both ends of the transverse guide post 6 are provided with mounting seats 61, which are detachably mounted on the top frame 1 for easy assembly and disassembly. Preferably, the mounting seats 61 are mounted on the top frame 1 by bolts. When adjusting the gap of the concrete formwork, selecting a suitable length of transverse guide post 6 according to the different thicknesses of the formwork can reduce the working stroke of the subsequent telescopic drive mechanism 3.

[0028] Furthermore, in this embodiment, the telescopic drive mechanism 3 includes a fixed base 31 and a telescopic drive component 32. The fixed base 31 is fixed on the top frame 1, and the telescopic drive component 32 is mounted on the fixed base 31 and connected to the corresponding movable frame 2. The telescopic drive component 32 telescopically moves the movable frame 2, enabling the two movable frames 2 to move closer and further apart. Preferably, the telescopic drive component 32 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0029] Furthermore, in this embodiment, the top frame 1 is square, with an observation port 11 in the middle and a handle 9 at the top. In practical applications, the handle 9 facilitates the operator in lifting the device.

[0030] Furthermore, in this embodiment, a T-shaped block 21 is provided on the inner side of the movable frame 2, and a T-shaped groove is provided on the pressure plate 4. The pressure plate 4 is installed on the movable frame 2 through the cooperation of the T-shaped groove and the T-shaped block 21, which facilitates disassembly and replacement. Preferably, the T-shaped block 21 is arranged horizontally.

[0031] Furthermore, in this embodiment, the movable frame 2 or the top frame 1 is equipped with a lighting lamp 12, which can be powered by its own power supply, so as to provide illumination for the adjustment of concrete formwork in dim environments.

[0032] Furthermore, in this embodiment, the inner side of the pressure plate 4 is provided with anti-slip protrusions 7. The anti-slip protrusions 7 can increase the friction between the pressure plate 4 and the concrete formwork, preventing slippage during pressure application. Preferably, the anti-slip protrusions 7 are evenly distributed on the inner surface of the pressure plate 4; the pressure plate 4 is made of stainless steel sheet.

[0033] Example 2: Figure 3 Another embodiment of the concrete formwork spacing adjustment device of this utility model is shown. The structure of the concrete formwork spacing adjustment device in this embodiment is basically the same as that in the first embodiment, except that: in this embodiment, the pressure plate 4 is connected to the heightening plate 5 through the docking part 41 to meet the pressure requirements of the higher concrete formwork.

[0034] Furthermore, in this embodiment, the connecting part 41 is a slot extending along the length of the pressure plate 4, and the top of the extension plate 5 is provided with a locking block 51 that mates with the slot. The pressure plate 4 and the extension plate 5 are connected by the slot and the locking block 51, making assembly and disassembly convenient. Preferably, the slot is a dovetail groove or a T-shaped groove. The bottom of the extension plate 5 may also be provided with a slot to facilitate further heightening to accommodate taller concrete formwork.

[0035] Furthermore, in this embodiment, anti-slip protrusions 7 are provided on the inner sides of both the pressure plate 4 and the raised plate 5. The anti-slip protrusions 7 can increase the friction between the pressure plate 4, the raised plate 5 and the concrete formwork, preventing slippage during pressure application. Preferably, the anti-slip protrusions 7 are also evenly distributed on the inner surface of the raised plate 5; the raised plate 5 is made of stainless steel sheet.

[0036] Furthermore, in this embodiment, a reinforcing member 52 is provided on the outer side of the heightening plate 5, and the reinforcing member 52 is detachably fixed to the movable frame 2 by a fixing block 8. The reinforcing member 52 is fixed to the movable frame 2 by the fixing block 8, which can improve the stability of the heightening plate 5. Preferably, both ends of the fixing block 8 are fixed to the reinforcing member 52 and the movable frame 2 by bolts, respectively, for easy assembly and disassembly.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
