Description

Technical Field

[0001] This utility model belongs to the field of concrete mold technology, specifically an air cushion type concrete molding mold. Background Technology

[0002] Concrete formwork is a crucial component of the building's main structural construction system. The formwork structure is erected on-site, and concrete is poured and vibrated inside to control the shape and dimensions of the main structure. In practice, concrete formwork construction is complex, and quality issues such as grout leakage and surface defects can easily occur during the construction phase, affecting the quality of the building's main structure.

[0003] To address the problems in concrete formwork construction, several new mold types have been proposed, including modular molds and slipform molds. Modular molds are assembled from standardized components (such as steel frames and plywood), offering advantages in flexibility and suitability for a wide range of structures. However, they suffer from poor reusability, low concrete surface quality after demolding, and difficulty in constructing complex shapes. Slipform molds, on the other hand, utilize integral, movable formwork and are commonly used for floor slab pouring. However, they require large lifting equipment; therefore, slipform molds need to be fabricated as a single layer, resulting in drawbacks such as large size, the need for heavy lifting equipment, poor mobility, and high cost.

[0019] This utility model discloses an air-cushion concrete molding mold. By setting the mold base plate and / or mold side plates as air-cushion flexible support plate components, the shape of the molding thin steel plate can be adjusted using a telescopic motor mounted on the support frame, meeting the requirements of complex shape construction. By placing an air-cushion membrane between the molding thin steel plate and the support frame, the internal pressure within the air-cushion membrane can be dynamically adjusted via a pressure control device during concrete molding. Thus, the air-cushion membrane can dynamically apply a supporting force to the molding thin steel plate. Specifically, concrete generates significant lateral pressure during pouring; increasing the gas pressure within the air-cushion membrane increases the molding thin steel plate's ability to withstand lateral pressure. Furthermore, the internal pressure of the air-cushion membrane can be adjusted in the early and late stages of concrete molding based on the concrete's hydrothermal temperature and volume, thereby eliminating internal stress and micro-cracks in the concrete. After concrete molding, the air-cushion membrane and telescopic rod also achieve rapid demolding. Specifically, the technical effects of this utility model are as follows:

[0020] (1) Multiple telescopic motors are used to provide distributed support for the forming thin steel plate, which can construct various shapes and designs. Air cushion film is used to provide support for the forming thin steel plate, so as to avoid deformation of the forming thin steel plate during the concrete forming process.

[0021] (2) According to the hydration requirements of concrete, the temperature and pressure of the medium inside the air cushion film are controlled, so as to adjust the concrete deformation and achieve the best curing state.

[0022] (3) Concrete molding and demolding are simple and easy to construct.

[0023] In summary, the air cushion concrete molding mold of this utility model uses an air cushion exoskeleton support system consisting of a support frame, a molding thin steel plate, and a telescopic motor to control the shape inside the mold, and achieves rapid demolding through air cushion contraction, which can improve the surface quality of concrete.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0033] like Figure 1 As shown, the air-cushion concrete molding mold of this embodiment includes a mold base plate 10 and mold side plates 20 mounted on the mold base plate 10. The mold base plate 10 and the mold side plates 20 form a molding box with an open top. The mold base plate 10 and / or the mold side plates 20 adopt an air-cushion flexible support plate assembly. Specifically, in this embodiment, the mold side plates 20 adopt an air-cushion flexible support plate assembly. Of course, in some other embodiments, the mold base plate 10 can also be set as an air-cushion flexible support plate assembly, such as... Figure 5 The diagram shown is a structural schematic of the mold base plate 2 as an air cushion type flexible support plate assembly.

[0034] Specifically, in this embodiment, the air-cushion flexible support plate assembly includes a support frame 31. A thin steel plate 32 for contacting concrete is provided on the inner side of the support frame 31 facing the forming box. Telescopic motors 33 are installed at intervals on the support frame 31, and the telescopic rods 34 of the telescopic motors 33 are used to adjust the shape of the thin steel plate 32. Preferably, the telescopic motors 33 are arranged in an array on the support frame 31. By controlling the length of the telescopic rods 34 of different telescopic motors 33, the position of the fulcrum of the thin steel plate 32 at the corresponding telescopic rod 33 position can be controlled, thereby allowing the thin steel plate 32 to form a specific shape structure through each fulcrum position to meet the requirements of complex construction. To provide support for the thin steel plate, this embodiment provides an air cushion film 35 for supporting the thin steel plate 32 and a pressure control device 45 for adjusting the internal pressure of the air cushion film 35 between the thin steel plate 32 and the support frame 31.

[0035] In this embodiment, a first through hole 351 is provided on the inner side of the air cushion film 35, corresponding to the telescopic rod 34. The telescopic rod 34 passes through the first through hole 351 and cooperates with the formed thin steel plate 32 to adjust the shape of the formed thin steel plate 32. Specifically, the air cushion film 35 needs to meet the sealing requirements. Therefore, in this embodiment, a first sealing component for sealing the first through hole 351 is provided between the telescopic rod 34 and the air cushion film 35.

[0036] Specifically, the end of the telescopic rod 34 and the formed thin steel plate 32 can be matched in various ways. For example, the end of the telescopic rod 34 can abut against the formed thin steel plate 32, or the end of the telescopic rod 34 and the formed thin steel plate 32 can be connected by a threaded connector 46.

[0037] Specifically, such as Figure 2 As shown, when the end of the telescopic rod 34 abuts against the formed thin steel plate 32, the formed thin steel plate 32 can slide along the end of the telescopic rod 34, meaning that the formed thin steel plate 32 has more degrees of freedom to achieve shape adjustment. At this time, the first sealing assembly includes two first sealing gaskets I36 sleeved on the telescopic rod 34 and located on both sides of the air cushion film 35; the end of the telescopic rod 34 is provided with a first external thread I341, and the end of the telescopic rod 34 is equipped with first clamping nuts I37 located on both sides of the air cushion film 35 for pressing and fixing the first sealing gaskets I36 onto the air cushion film 35. The first clamping nuts I37 are threadedly engaged with the first external thread I341. Thus, the requirement that the formed thin steel plate 32 can slide along the end of the telescopic rod 34 can be satisfied, and the first through hole 351 can be sealed to meet the requirement of internal pressure adjustment of the air cushion film 35.

[0038] Specifically, such as Figure 3As shown, when the end of the telescopic rod 34 is connected to the formed thin steel plate 32 using a threaded connector 46, the first sealing assembly includes a first sealing gasket II 38 sleeved on the telescopic rod 34 and located outside the air cushion film 35; the end of the telescopic rod 34 is provided with a first external thread II 342, and the end of the telescopic rod 34 is equipped with a first clamping nut II 39 located outside the air cushion film 35 for pressing and fixing the first sealing gasket II 38 and the air cushion film 35 onto the formed thin steel plate 32. The first clamping nut II 39 is threadedly engaged with the first external thread II 342. Similarly, this satisfies both the requirement of connecting the telescopic rod 34 and the formed thin steel plate 32 using a threaded connector and the requirement of sealing the first through hole 351 to meet the requirement of adjusting the internal pressure of the air cushion film 35.

[0039] like Figure 4 As shown, in this embodiment, the outer air cushion film 35 covers the inner side of the telescopic motor 33, and the outer air cushion film 35 has a second through hole 352 corresponding to the telescopic motor 33 for the telescopic rod 34 to pass through. A second sealing assembly for sealing the second through hole 352 is provided between the telescopic rod 34 and the air cushion film 35. Specifically, the second sealing assembly includes two second sealing gaskets 40 sleeved on the telescopic rod 34 and located on both sides of the air cushion film 35; the end of the telescopic rod 34 has a second external thread 343, and the end of the telescopic rod 34 is equipped with second clamping nuts 41 located on both sides of the air cushion film 35 for pressing and fixing the second sealing gaskets 40 onto the air cushion film 35. The second clamping nuts 41 are threadedly engaged with the second external thread 343. In this way, the requirement of sealing the second through hole 352 can be met.

[0040] This embodiment of the air cushion concrete molding die also includes a control area 42 located outside the support frame 31. The control area 42 contains a controller 43 and a motor control circuit 44 corresponding to each telescopic motor 33. A pressure control device 45 is installed within the control area 42. The controller 43 is electrically connected to the motor control circuit 44 and the pressure control device 45. Thus, the controller 43 can control the extension and retraction length of the telescopic rod 34 of the corresponding telescopic motor 33 through the motor control circuit 44, thereby controlling the shape of the formed thin steel plate 32. The controller 43 can also control the pressure control device 45 to inject a medium into the air cushion membrane 35 to increase the internal pressure of the air cushion membrane 35 or to extract the medium to decrease the internal pressure of the air cushion membrane 35, thereby controlling the internal pressure of the air cushion membrane 35. Specifically, the medium can be gas or liquid, depending on the concrete material, and will not be elaborated further.

[0041] The operation procedure for concrete molding using the air cushion concrete molding mold of this embodiment is as follows:

[0042] (1) Construction preparation: According to the shape and structure of the molded concrete, select the bottom plate 10 and / or the side plate 20 of the mold as an air cushion flexible support plate assembly, and assemble the bottom plate 10 and the side plate 20 of the mold into a molded box with an open top.

[0043] (2) Concrete pouring and vibration: Concrete transportation and on-site inspection, and layered pouring and vibration;

[0044] (3) Curing: The temperature and pressure of the medium inside the air cushion film 35 can be controlled according to the needs of the concrete, thereby cooling the concrete and causing deformation and expansion.

[0045] (4) Demolding control: First, release the medium inside the air cushion film 35, then retract the telescopic rod 34, and finally remove the mold.

[0046] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
