Description
Technical Field
[0001] This utility model belongs to the field of concrete testing technology, and in particular relates to an indoor concrete block casting mold. Background Technology
[0002] Due to construction techniques, structural design, and requirements for concrete temperature control and crack prevention, concrete structures need to be poured in layers and sections, introducing interfaces between these non-simultaneously poured concrete structures. Concrete structures are prone to damage at these interfaces. Therefore, in-depth research on the properties of these non-simultaneously poured concrete interfaces is of great significance for ensuring the long-term safe and stable operation of concrete structures.
[0003] The performance testing of concrete in hydraulic structures is based on SL / T 352-2020 "Test Procedure for Hydraulic Concrete". However, there is currently no specific procedure for the performance testing of concrete interfaces that are not poured simultaneously. The main approach is to refer to the test procedure for hydraulic concrete, in which two parts of the concrete structure are poured simultaneously in a hydraulic concrete casting mold. However, this method cannot guarantee the position of the concrete interface in the overall specimen. At the same time, the existing concrete specimen molds will face the problem of demolding difficulties after the concrete has completely solidified.
[0004] To address these issues, existing concrete block casting mold designs have undergone several improvements, but many shortcomings remain. For example, while some molds can achieve block casting, they cannot ensure that the interface between the two concrete sections is centered within the mold. Furthermore, some molds cannot adapt to interface requirements under varying roughness conditions in engineering projects, affecting the accuracy of experimental results. Simultaneously, the demolding process is complex, requiring significant manpower and time, thus reducing construction efficiency. Summary of the Invention
[0005] The purpose of this invention is to address the problems existing in the prior art by providing an indoor concrete block casting mold that ensures the interface is in the middle, supports concrete interfaces with different roughness, and also facilitates demolding.
[0006] To achieve the above objectives, the utility model adopts the following technical solution: an indoor concrete block casting mold, including a base plate, a mold frame on the base plate, a lifting component on the base plate and located inside the mold frame, a movable plate on the lifting component that contacts the inner wall of the mold frame, a bracket on the movable plate that contacts the inner wall of the mold frame on one side, a corrugated baffle on the other side of the bracket, and the corrugated baffle located in the middle of the mold frame.
[0007] The above technical solution utilizes a support and corrugated baffle to divide the space inside the mold frame into two parts from the middle during concrete block casting. Concrete is poured into the cavity on the side furthest from the support. After the concrete on that side solidifies, the support and corrugated baffle are removed, and concrete is poured again into the cavity on the other side. This allows for the simultaneous casting of two concrete structures. In particular, the corrugated baffle, located in the middle of the mold frame, effectively ensures that the interface between the two concrete parts is centered, allowing for more accurate in-depth studies of the interface properties of the simultaneously cast concrete. Moreover, the corrugated baffle can meet the interface requirements of different roughnesses. Furthermore, after both concrete parts have solidified, the movable plate is lowered by the shrinkage lifting device, and the concrete block automatically detaches from the inner wall of the mold frame under its own weight, making it convenient for operators to remove the mold frame. This effectively reduces the difficulty and steps of demolding the concrete block.
[0008] Optionally, a positioning groove is provided on the base plate, and a positioning frame that can be inserted into the positioning groove is provided at the bottom of the mold frame. This ensures the accurate positioning and stable installation of the mold frame on the base plate, and improves the reliability and durability of the mold.
[0009] Optionally, the inner wall of the mold frame is polished, which helps to reduce the friction between the concrete and the mold frame, reduce the adhesion between the concrete and the inner wall of the mold frame, and make it easier to demold the concrete. The outer wall of the mold frame is provided with a handling handle to facilitate the handling and movement of the mold and improve construction efficiency.
[0010] Optionally, the lifting component includes multiple airbags mounted on the base plate. One end of each airbag is provided with an air pipe, and the other end of all the air pipes is connected to a delivery pipe. An air valve is provided on the delivery pipe.
[0011] In the above technical solution, an airbag is used as the core of the lifting component. The lifting and lowering of the movable plate is controlled by air pipes and delivery pipes, which makes it easier for the solidified concrete to detach from the inner wall of the mold frame. In addition, the design of the airbag makes the lifting operation more stable and reliable.
[0012] Optionally, the four sides of the movable plate are provided with sealing strips at the joints with the inner wall of the mold frame, which ensures tight contact between the movable plate and the inner wall of the mold frame, prevents concrete from seeping out from the gaps during the pouring process, and improves the molding quality.
[0013] Optionally, a pre-reserved notch is provided at the bottom of one side of the mold frame, and all the air pipes extend out of the mold frame through the pre-reserved notch. The pre-reserved notch facilitates the inflation and deflation of the airbag and improves the practicality of the lifting component.
[0014] Optionally, the bracket is an inverted frame, with reinforcing rods welded crosswise on the inner side of the bracket, and mounting holes are provided on the side of the bracket that contacts the corrugated baffle. The overall structure is simple.
[0015] Optionally, the corrugated baffle includes multiple straight plates and multiple curved plates, which are welded together in an alternating manner. The side of the straight plates and curved plates that contacts the concrete is a polished surface. The corrugated baffle has side strips on both sides, and the side strips are connected to the inner wall of the mold frame. The side of the straight plate facing the bracket has fixing bolts that pass through the mounting holes.
[0016] In the above technical solution, the corrugated baffle is formed by interlacing and welding multiple straight and curved panels. The shape and curvature of the corrugated baffle can be adjusted as needed to adapt to the molding requirements of different concrete blocks. The surfaces of the straight and curved panels that contact the concrete are polished, which helps to reduce friction and improve demolding efficiency. Edge strips are provided on both sides of the corrugated baffle to ensure tight contact between the corrugated baffle and the inner wall of the mold frame.
[0017] Optionally, the curved panel is available in various models with different curvatures, which can be used to form concrete interfaces in different states according to requirements.
[0018] Optionally, the height of the corrugated baffle is higher than the height of the mold frame.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When pouring concrete test blocks, the space inside the mold frame is divided into two parts from the middle using a support and corrugated baffle. Concrete is poured in the cavity on the side away from the support. After the concrete on that side solidifies, the support and corrugated baffle are removed, and concrete is poured again in the cavity on the other side. This achieves non-simultaneous pouring of two concrete structures. In particular, the corrugated baffle is located in the middle of the mold frame, which can effectively ensure that the interface between the two concrete parts is in the center position, so as to allow for more accurate in-depth research on the interface performance of non-simultaneously poured concrete. Moreover, the use of corrugated baffle can meet the interface requirements of different roughnesses; 2. After both concrete parts have solidified, the movable plate is lowered by the shrinkage lifting component. Under its own gravity, the concrete test block will automatically detach from the inner wall of the mold frame, thereby... 1. The mold frame is easy for operators to remove, effectively reducing the difficulty and steps of demolding concrete test blocks; 2. The inner wall of the mold frame is polished, which helps reduce the friction between the concrete and the mold frame, reduces the adhesion between the concrete and the inner wall of the mold frame, and makes it easier to demold the concrete; 3. The outer wall of the mold frame is equipped with a handling handle, which facilitates the handling and movement of the mold and improves construction efficiency; 4. An airbag is used as the core of the lifting component. The lifting and lowering of the movable plate is controlled by air pipes and delivery pipes, which makes it easier for the solidified concrete to separate from the inner wall of the mold frame. In addition, the airbag design makes the lifting operation more stable and reliable; 5. The corrugated baffle is made of multiple straight plates and curved plates welded together. The shape and curvature of the corrugated baffle can be adjusted as needed to adapt to the molding requirements of different concrete blocks. The side of the straight plates and curved plates that contact the concrete are polished, which helps reduce friction and improve demolding efficiency. There are edge strips on both sides of the corrugated baffle to ensure close contact between the corrugated baffle and the inner wall of the mold frame. Attached Figure Description

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] like Figure 1 As shown in Figure 2, this embodiment details an innovative design scheme for an indoor concrete block casting mold. The mold mainly consists of key components such as a base plate 1, a mold frame 4, lifting components 2, a movable plate 3, a support 5, and a corrugated baffle 6. The base plate 1 houses the mold frame 4, and the lifting components 2 are cleverly arranged inside the mold frame 4. Movable plates 3 are mounted on these lifting components 2, with one side of the movable plate 3 in close contact with the inner wall of the mold frame 4. A support 5 is further mounted on the movable plate 3, and a corrugated baffle 6 is mounted on the other side of the support 5. This baffle is precisely located in the center of the mold frame 4, providing a precise boundary for concrete pouring.
[0028] During the concrete block pouring process, the clever cooperation between the support 5 and the corrugated baffle 6 divides the space inside the mold frame 4 into two parts, with the corrugated baffle 6 occupying the central area. First, concrete is poured into the cavity on the side furthest from the support 5. After the concrete on that side solidifies, the support 5 and the corrugated baffle 6 are removed, and then concrete is poured into the cavity on the other side. This non-simultaneous pouring design not only achieves segmented pouring of the concrete structure, but also ensures that the interface between the two concrete sections is precisely centered, thanks to the corrugated baffle 6 being located in the center of the mold frame 4. This is of great significance for in-depth research on the interface performance of concrete poured non-simultaneously. After both concrete sections have solidified, the movable plate 3 is lowered by the retractable lifting component 2, and the concrete block automatically detaches from the inner wall of the mold frame 4 under its own gravity, greatly simplifying the demolding operation and reducing the difficulty and steps for operators.
[0029] like Figure 2-4 As shown, in this embodiment, a positioning groove 11 is provided on the base plate 1, and a positioning frame 41 that can be inserted into the positioning groove 11 is provided at the bottom of the mold frame 4. This ensures the accurate positioning and stable installation of the mold frame 4 on the base plate 1, and improves the reliability and durability of the mold.
[0030] It should be noted that the inner wall of the mold frame 4 in this embodiment is polished, which helps to reduce the friction between the concrete and the mold frame 4, reduce the adhesion between the concrete and the inner wall of the mold frame 4, and make it easier to demold the concrete. The outer wall of the mold frame 4 is provided with a handling handle, which facilitates the handling and movement of the mold and improves construction efficiency.
[0031] like Figure 2-3 As shown, Figure 2-3 As shown, the lifting component 2 employs multiple airbags 21 mounted on the base plate 1. One end of each airbag 21 has an air pipe 22, and the other end of all air pipes 22 is connected to a conveying pipe 23, which is equipped with an air valve. In this technical solution, the airbag 21 serves as the core of the lifting component 2, controlling the lifting and lowering of the movable plate 3 via the air pipes 22 and the conveying pipe 23, making it easier for the solidified concrete to detach from the inner wall of the mold frame 4. Furthermore, the design of the airbag 21 also makes the lifting operation smoother and more reliable.
[0032] It should be noted that a pressure gauge can also be installed between the delivery pipe 23 and the air valve. When air is pumped into the airbag 21, the pressure gauge can be used to determine whether the air pressure inside the airbag 21 has reached the predetermined pressure.
[0033] In this embodiment, the four sides of the movable plate 3 are provided with sealing strips at the joints with the inner wall of the mold frame 4, which ensures close contact between the movable plate 3 and the inner wall of the mold frame 4, prevents concrete from seeping out from the gaps during the pouring process, and improves the molding quality.
[0034] like Figure 1 As shown, a reserved notch 42 is provided at the bottom of one side of the mold frame 4. All the air pipes 22 extend out of the outside of the mold frame 4 through the reserved notch 42. The reserved notch 42 facilitates the inflation and deflation of the airbag 21 and improves the practicality of the lifting component 2.
[0035] like Figure 2 As shown, bracket 5 is an U-shaped frame, which is welded from aluminum alloy profiles. Reinforcing rods are cross-welded to the inner side of bracket 5, and mounting holes are provided on the side of bracket 5 that contacts the corrugated baffle 6. The overall structure is simple.
[0036] The corrugated baffle 6 includes multiple straight plates 61 and multiple curved plates 62. The straight plates 61 and curved plates 62 are welded together in an alternating manner. The side of the straight plates 61 and curved plates 62 that contacts the concrete is a polished surface. The corrugated baffle 6 is provided with side strips 63 on both sides. The side strips 63 are connected to the inner wall of the mold frame 4. The side of the straight plate 61 facing the bracket 5 is provided with fixing bolts 64 that pass through the mounting holes.
[0037] In the above technical solution, the corrugated baffle 6 is formed by interlacing and welding multiple straight plates 61 and curved plates 62. The shape and curvature of the corrugated baffle 6 can be adjusted as needed to adapt to the molding requirements of different concrete blocks. The surfaces of the straight plates 61 and curved plates 62 that contact the concrete are polished, which helps to reduce friction and improve demolding efficiency. Edge strips 63 are provided on both sides of the corrugated baffle 6 to ensure close contact between the corrugated baffle 6 and the inner wall of the mold frame 4.
[0038] In this embodiment, the curved panel 62 is available in various models, each with a different curvature, to form different concrete interfaces as needed. The height of the corrugated baffle 6 is higher than the height of the mold frame 4.
[0039] In this embodiment, in order to make the entire mold lighter and easier to construct, all components except the bracket 5 are made of ABS plastic.
[0040] The working principle of the above embodiment is as follows: the mold achieves segmented pouring and demolding of concrete through the coordinated work of a series of carefully designed components. First, the space inside the mold frame 4 is divided into two cavities by the support 5 and the corrugated baffle 6 located in the middle of the mold frame 4. Concrete is poured into the cavity away from the support 5 and allowed to solidify. Then, the support 5 and the corrugated baffle 6 are removed, and concrete is poured into the cavity on the other side. This segmented pouring method allows the two parts of concrete to be poured at different times, while ensuring that the interface is accurately located in the center. After the concrete solidifies, the movable plate 3 is lowered by controlling the lifting component 2 of the airbag 21 on the base plate 1. The concrete specimen is automatically detached from the inner wall of the mold frame 4 by its own weight, thus achieving demolding. Throughout the process, the positioning groove 11 and the positioning frame 41 ensure the accurate positioning and stable installation of the mold frame 4, the polished inner wall and the handling handle improve construction efficiency, the sealing strip ensures the pouring quality, and the reserved notch 42 facilitates the inflation and deflation of the airbag 21. The adjustable design of the corrugated baffle 6 allows it to adapt to the molding requirements of different concrete blocks, while the use of ABS plastic products reduces the weight of the mold and improves the convenience of construction.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
