Description

Technical Field

[0001] The utility model relates to the technical field of building moulds, in particular to a reusable mould for casting. Background Art

[0002] Nowadays, concrete cover repair is a common method of reinforcing and repairing concrete structures. When concrete structures are subjected to chloride ion erosion, freeze-thaw cycles or fire, the concrete cover will be damaged, which will reduce the strength of the cover and affect the bearing capacity of the structure. The mechanical properties of the structure can be improved by repairing the cover.

[0003] The most effective way to repair a damaged concrete cover is to knock it off and recast a new one. When casting a new cover, controlling the thickness of the cover, casting quality and surface flatness are key considerations, which can be achieved by setting up formwork.

[0004] If the traditional method of forming with wooden or steel molds is adopted, it is time-consuming, labor-intensive and resource-intensive. The wooden mold is almost worn out when it is removed. Although it can be reused, the number of times is limited. Although the steel mold can be recycled, it is more troublesome to install and disassemble and is relatively expensive. In addition, the protective layer of wooden and steel molds is prone to hollowing after pouring. Utility Model Content

[0013] S5: After the poured protective layer solidifies, remove the clamp, remove the adjacent acrylic sheet from the open side, then remove the hinge and then remove the adjacent acrylic sheet, and finally remove the entire mold.

[0014] As a further improvement, four groups of hinge parts are arranged at corresponding intervals between two adjacent acrylic plates, and the hinge parts are locked to the acrylic plates by fasteners.

[0015] As a further improvement, one side of the hinge is locked to the inner side of one of the acrylic plates, and the other side is locked to the outer side of the other acrylic plate.

[0031] Example

[0032] Combination Figures 1 to 3 The present embodiment provides a reusable mold for casting, comprising a transparent acrylic plate 1, a hinge 2 and a clamp 3; the acrylic plate 1 is in the shape of a long plate, and four acrylic plates 1 are enclosed to form a rectangular column frame; two adjacent acrylic plates 1 at three corners of the column frame are connected and closed by multiple opening and closing parts, and two adjacent acrylic plates 1 at another corner are directly abutted to reserve an open edge; the middle, upper and lower parts of the column frame are respectively provided with clamps 3, and hinges 2 for connecting adjacent acrylic plates 1 are provided above and below the clamps 3.

[0033] The above-mentioned mold enables the construction workers to clearly observe the concrete repair process, including the filling of concrete, the formation of bubbles and voids, etc., through the transparent acrylic plate 1, which helps to find problems in time and make adjustments, thereby improving the reliability of the repair effect. Through the precise design of the column frame, it can be ensured that the concrete is filled to the correct position and size, thereby ensuring that the thickness and shape of the protective layer meet the design requirements. The design of the opening and closing parts and the abutting edges makes the opening and closing of the mold simple and convenient. The construction workers can easily install and disassemble the mold, which improves the construction efficiency. Since the mold is made of durable materials and has a reasonable design, it can be reused many times, saving costs and reducing the impact on the environment. It significantly improves the efficiency and quality of the repair of the protective layer of reinforced concrete columns, and can also ensure the safety and controllability during the construction process.

[0034] The steps of reusing the mold are as follows:

[0035] S1: Cut out four transparent acrylic plates 1 according to the required size of the reinforced concrete column and assemble the column frame;

[0036] S2: The hinge member 2 is locked on two adjacent acrylic plates 1, and the four corners of the column frame are connected by the hinge member 2 to form three closed edges, and one open edge is reserved;

[0037] S3: Apply a release agent on the inner side of the column frame, place the column frame support in the core area of ​​the reinforced concrete column, and after fixing the position, constrain the clamp 3 at the upper, middle and lower parts of the column frame;

[0038] S4: Pour concrete or mortar into the column frame, and observe through the acrylic plate 1 whether the poured protective layer is hollow. If hollowing occurs, directly knock on the acrylic plate 1 or further stir it evenly;

[0039] S5: After the poured protective layer solidifies, the clamp 3 is removed, the adjacent acrylic plate 1 is removed from the open side, and then the hinge 2 is removed to further remove the adjacent acrylic plate 1, and finally the entire mold is removed.

[0040] The above-mentioned reusable method implemented based on the mold provides a fixed column frame by the mold, so that concrete or mortar can be accurately cast in a predetermined position and shape, ensuring that the size and shape of the protective layer meet the design requirements and improve the construction quality. The transparent acrylic plate 1 allows real-time monitoring of the filling condition and quality of the protective layer during the construction process, timely detection of problems and measures to be taken to adjust them, ensuring the reliability and consistency of the repair effect. The design of the mold takes into account the disassembly process, making the disassembly operation relatively simple and causing no additional damage to the protective layer. At the same time, it can also protect the integrity of the mold for next use. Reusability means that it can be used multiple times, saving material and manufacturing costs, and reducing the impact on the environment. It provides an efficient and controllable workflow for the repair of reinforced concrete column protective layers, which can ensure the quality and safety of the repair work, while also saving costs and having significant effects.

[0041] like Figure 1 As shown, in this embodiment, two adjacent acrylic plates 1 are spaced apart and provided with four sets of hinge members 2, and the hinge members 2 are locked on the acrylic plates 1 by fasteners 4. Preferably, the fasteners 4 are screws adapted to the hinge members 2.

[0042] Furthermore, one side of the hinge member 2 is locked to the inner side of one of the acrylic plates 1, and the other side is locked to the outer side of the other acrylic plate 1. Thus, the hinge member 2 firmly connects the acrylic plates 1 together, ensuring the stability and reliability of the mold during use, and its tight connection helps prevent the concrete or mortar from overflowing or deforming, thereby ensuring the accuracy and consistency of the repair layer.

[0043] In addition, the hinge 2 makes the disassembly of the mold simple and convenient. The acrylic plate 1 can be easily separated by removing the hinge 2, thereby quickly completing the disassembly process of the mold, saving time and labor costs. The design of the hinge 2 simplifies the installation and disassembly process of the mold, making the operation more convenient and quick. And the different connection methods of the inner side and the outer side make it possible to complete the assembly or disassembly of the mold by simply locking or unlocking the hinge 2 on the outer side, without the need for additional professional tools or complicated operation steps.

[0044] It should be mentioned that the area enclosed by the column frame is comparable to the size of the reinforced concrete column, and the protective layer of the reinforced concrete column is formed on the inner side of the column frame.

[0045] In this embodiment, one of the clamps 3 is bound at the center of the column frame, and two of the clamps 3 are symmetrically bound above and below the column frame, and an acrylic plate 1 extending upward or downward is reserved. The clamps 3 are bound at the center of the column frame and symmetrically above and below, which ensures the stability and reliability of the mold during use. The stable constraint can effectively prevent the mold from moving or tilting when pouring concrete or mortar, ensuring the accuracy and uniformity of the protective layer. And the acrylic plate 1 extending upward or downward is reserved so that the height of the mold can be flexibly adjusted, and the height of the mold can be adjusted according to the specific repair requirements to ensure that the protective layer after repair is covered in place and achieve the desired effect. Therefore, the arrangement of the clamps 3 simplifies the installation and use process of the mold, and the mold can be easily positioned at the desired position, and the mold can be fixed by the constraints of the clamps 3, saving time and labor costs and improving construction efficiency.

[0046] Specifically, the clamp 3 includes a clamp body sleeved outside the column frame, and a clamp head for adjusting the tightness of the clamp body. Obviously, the clamp head and the clamp body cooperate to constrain the column frame, which greatly improves stability and easy disassembly.

[0047] Preferably, each hinge member 2 is centrally arranged in the frame space defined by the clamp member 3. In this way, the hinge member 2 and the clamp member 3 cooperate with each other to more stably bind the acrylic plate 1 to the frame.

[0048] In this embodiment, a plurality of connected acrylic panels 1 are assembled into a column frame during pouring, and after pouring, the open side is switched to a plurality of panels arranged in a row. After a plurality of connected acrylic panels 1 are assembled into a column frame, they are poured, so that the protective layer is formed at one time, avoiding the joint problem caused by multiple splicing, and improving the consistency and quality of the protective layer. In addition, the time for disassembly and reassembly of the mold is reduced, while also saving human resources and improving construction efficiency. The operation mode of switching from the open side to a plurality of panels arranged in a row can make it easier to disassemble the mold, reduce damage and wear to the mold, and extend the service life of the mold. The plurality of panels arranged in a row allow the protective layer to flow more evenly during the pouring process, reduce the generation of gaps and bubbles, and improve the compactness and quality of the protective layer. In addition, the amount of concrete or mortar used can be better controlled, reducing material waste and saving costs.

[0049] The head and tail of the column frame are hollowed out, and the whole is transparent to facilitate observation of the internal pouring conditions. The transparent design allows the constructor to observe the pouring conditions of concrete or mortar in real time, including fluidity, filling conditions, and whether there are gaps, etc., which helps to find problems and make adjustments in time, improving the accuracy and quality of the repair work. The hollow design of the head and tail facilitates pouring construction on the one hand, and on the other hand, it is convenient to clean and maintain the inside of the mold, keep the mold clean and tidy, and extend the service life of the mold.

[0050] The specifications and sizes of the four acrylic plates 1 are consistent.

[0051] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
