Description

Technical Field

[0001] This utility model relates to the field of concrete formwork technology, and more specifically to a concrete formwork structure that shortens the concrete curing cycle. Background Technology

[0002] The reason why concrete can gradually solidify and harden after being poured is mainly due to the hydration of cement. Hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that concrete has suitable hardening conditions and its strength continues to increase, it must be cured. In some construction projects, concrete blocks are used for stacking and construction. When pouring concrete blocks, formwork is needed to cure them to ensure the solidity of the concrete blocks.

[0003] For example, the existing technology disclosure number CN215038538U discloses a concrete formwork for shortening the concrete curing cycle. This utility model has a reasonable structural design and is easy to use. It adopts a closed container and introduces steam, which can greatly shorten the curing cycle of concrete blocks and improve efficiency. At the same time, it can provide a good clamping and fixing effect on the formwork during curing, avoiding the impact of vibration and other factors on the quality of concrete blocks, and can meet various needs.

[0004] However, the existing technology described above still has the following problems in use: since concrete will solidify after curing, workers need to first open the box cover and then disassemble the concrete formwork to retrieve the material. This process is time-consuming and labor-intensive, seriously affecting curing efficiency. Based on this, the present invention provides a concrete formwork structure that shortens the concrete curing cycle. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a concrete formwork structure for shortening the concrete curing cycle. It consists of a base, a formwork frame, and an outer shell, and features high sealing performance, which effectively reduces steam leakage and thus significantly shortens the curing cycle. At the same time, the outer shell and the formwork frame can be separated from the base, making it easy to remove the molded concrete blocks, simplifying the demolding operation, accelerating the removal of finished products, and further improving the overall efficiency of the curing operation, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete formwork structure for shortening the concrete curing cycle, comprising a base, a frame-shaped installation groove on the top of the base, an outer shell installed inside the frame-shaped installation groove, a formwork frame inside the outer shell, the formwork frame being composed of four side formworks, a first sealing strip being provided between the bottom of the side formworks and the base, and between two adjacent side formworks, a feeding pipe penetrating through the center of the top of the outer shell, and lifting components being fixed between the two sides of the base and the outer shell for driving the outer shell to lift.

Connecting plates are fixedly attached to the top of the piston rods of the two electric push rods. The connecting plates are fixed to the top of one side of the outer casing. The lifting of the outer casing is driven by the electric push rods, making it more time-saving and labor-saving to use.

[0008] In a preferred embodiment, a protective cover is fixedly provided on the top of each of the two mounting bases. The protective cover is fitted over the outside of the electric push rod, and the top of the piston rod of the electric push rod extends through the protective cover and is provided with a sealing ring between the piston rod and the protective cover.

[0009] In a preferred embodiment, the top of the outer shell has a plurality of mounting holes arranged in a ring array, and each mounting hole is provided with a fastening bolt. The outer shell is detachably connected to a plurality of side templates by fastening bolts. The outer shell is connected to the side templates by fastening bolts, which facilitates the subsequent disassembly and replacement of the side templates.

[0010] In a preferred embodiment, a second sealing strip is provided between the outer shell and the frame mounting groove to fill the gap. The second sealing strip can effectively improve the sealing between the outer shell and the frame mounting groove, and between the cover plate and the opening, to prevent leakage.

[0011] In a preferred embodiment, the top of the feeding pipe is threaded with a threaded cap, and the top of the threaded cap has an air inlet pipe and an air outlet pipe that are connected to the inside of the template frame.

[0012] In a preferred embodiment, each side template has multiple equally spaced positioning rods fixed at its bottom. The base has positioning holes at its top, the same number of which are the positioning rods. The positioning rods are inserted into the positioning holes. By using the positioning rods in conjunction with the positioning holes, the stability of the side template can be improved to a certain extent.

[0013] The technical effects and advantages of this utility model are as follows: 1. The concrete curing template structure of this utility model consists of a base, a template frame, and an outer shell, which has high sealing performance, thereby effectively reducing steam leakage and significantly shortening the curing cycle. At the same time, the outer shell and the template frame are moved upward synchronously by an electric push rod, so that after they are separated from the base, the workers can easily take out the formed concrete blocks, simplifying the demolding operation, speeding up the removal of finished products, and further improving the overall efficiency of the curing operation.

[0017] 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.

[0018] Refer to the instruction manual appendix Figures 1-5 This utility model provides a concrete formwork structure for shortening the concrete curing cycle, including a base 1, a frame-shaped installation groove 2 on the top of the base 1, an outer shell 3 installed inside the frame-shaped installation groove 2, a template frame 4 inside the outer shell 3, the template frame 4 being composed of four side templates 41, a first sealing strip 5 being provided between the bottom of the side template 41 and the base 1, and between two adjacent side templates 41, and a feeding pipe 6 penetrating through the center of the top of the outer shell 3.

[0019] Lifting components 7 are fixedly provided between the two sides of the base 1 and the outer shell 3 for driving the outer shell 3 to lift. Specifically, the lifting components 7 include mounting seats 71 fixed on the base 1, electric push rods 72 are fixedly embedded on the top of the two mounting seats 71, and connecting plates 73 are fixedly provided on the top of the piston rods of the two electric push rods 72. The connecting plates 73 are fixed to the top of one side of the outer shell 3.

[0020] The top of the feeding pipe 6 is threadedly connected to a threaded cap 13, and the top of the threaded cap 13 is through an air inlet pipe 14 and an air outlet pipe 15. Both the air inlet pipe 14 and the air outlet pipe 15 are connected to the inside of the template frame 4.

[0021] The formwork structure for curing concrete, consisting of a base 1, a template frame 4, and an outer shell 3, features high sealing performance. In practical use, the threaded cap 13 of the feeding pipe 6 is first opened, and the concrete to be cured is injected into the cavity formed by the template frame 4, outer shell 3, and base 1. Then, the threaded cap 13 of the feeding pipe 6 is tightened, and steam is introduced into the cavity through the air inlet pipe 14 for curing. Simultaneously, an exhaust pipe 15 with a valve is provided to regulate the exhaust volume. During this process, steam curing can be completed simultaneously with the concrete during the shaping stage, significantly shortening the curing cycle. When the concrete curing is complete and needs to be removed, the outer shell 3 is driven by an electric push rod 72, which moves the template frame 4 upwards, separating them from the base 1. Workers can then easily remove the formed concrete block. This design simplifies the demolding operation, speeds up the removal of finished products, and further improves the overall efficiency of the curing operation.

[0022] In this embodiment, a second sealing strip 12 for filling gaps is provided between the outer shell 3 and the frame mounting groove 2. The second sealing strip 12 can effectively improve the sealing between the outer shell 3 and the frame mounting groove 2, and between the cover plate and the opening, to prevent leakage.

[0023] Refer to the instruction manual appendix Figures 1-5 Both mounting bases 71 are fixedly equipped with protective covers 8 on their tops. The protective covers 8 are fitted over the outside of the electric push rod 72. The top of the piston rod of the electric push rod 72 passes through the protective covers 8 and a sealing ring 9 is provided between the piston rod and the protective covers 8. The protective covers 8 provide a sealing function on the outside of the electric push rod 72, which can extend the service life of the electric push rod 72. In addition, the sealing ring 9 can block water mist adhering to the piston rod of the electric push rod 72 to a certain extent, thereby improving the sealing effect.

[0024] The top of the outer shell 3 has multiple mounting holes 10 arranged in a ring array. Each mounting hole 10 is equipped with a fastening bolt 11. The outer shell 3 is detachably connected to multiple side templates 41 by the fastening bolts 11. The outer shell 3 is connected to the side templates 41 by the fastening bolts 11, which facilitates the subsequent disassembly and replacement of the side templates 41.

[0025] Furthermore, a plurality of equally spaced positioning rods 16 are fixedly provided at the bottom of each side template 41, and the top of the base 1 is provided with the same number of positioning holes 17 as the positioning rods 16. The positioning rods 16 are inserted into the positioning holes 17. By using the positioning rods 16 and the positioning holes 17 to cooperate, the stability of the side template 41 can be improved to a certain extent.

[0026] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
