Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a construction formwork device for building engineering. Background Technology

[0002] The construction process of cast-in-place irrigation canals includes: excavating trenches, laying subgrade, installing formwork, pouring concrete, and finishing and curing. Among these, the formwork system is a key component in ensuring structural dimensions, surface quality, and construction efficiency.

[0003] In actual construction environments, the joints between two steel formwork panels are prone to becoming weak points due to compression, which often leads to grout leakage. This can cause honeycomb-like textures, holes, and exposed reinforcement on the concrete surface, severely affecting the appearance quality of the concrete and reducing its structural strength and durability. Therefore, a formwork device that can reinforce the joints is needed to solve the current problems. Utility Model Content

[0004] This utility model addresses the aforementioned problems by providing a construction formwork device for building engineering. It can effectively prevent concrete slurry leakage, and the reinforcing plate is embedded in the groove of the steel formwork to provide rigid support, ensuring the stability of the joint area. It has good angle adaptability and can meet the construction direction requirements of linear structures such as water channels in complex terrain, significantly improving the applicability, flexibility and engineering application scope of the formwork device.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a construction formwork device for building engineering, including steel formwork, flexible plate, reinforcing plate, hinge rod and groove. The two sides of the flexible plate are respectively attached to the panel of the steel formwork. Reinforcing plates are connected to both sides of one side of the flexible plate. The two reinforcing plates are hinged by the hinge rod. Grooves are opened on both sides of the panel of the steel formwork. The corresponding reinforcing plates are embedded in the corresponding grooves. The reinforcing plates are detachably connected to the corresponding steel formwork. The structure composed of the reinforcing plates, the hinge rods and the flexible plate fills the joint between the two steel formworks.

[0006] Furthermore, it also includes a through groove, a support shaft, a rotating block, a lock hole, and a locking element. The steel template has through grooves on both sides, and the through grooves are connected to the groove. The support shaft is fixedly connected to the reinforcing plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1-7 As shown in the figure, this embodiment provides a construction formwork device for building engineering, including a steel formwork 1, a flexible plate 2, a reinforcing plate 3, a hinge rod 4, and a groove 5. The two sides of the flexible plate 2 are respectively attached to the panel of the steel formwork 1. The two sides of one side of the flexible plate 2 are connected to the reinforcing plates 3. The two reinforcing plates 3 are hinged by the hinge rod 4. The two sides of the panel of the steel formwork 1 are provided with grooves 5, and the corresponding reinforcing plates 3 are embedded in the corresponding grooves 5. The reinforcing plates 3 are detachably connected to the corresponding steel formwork 1. The structure composed of the reinforcing plates 3, the hinge rod 4, and the flexible plate 2 fills the joint between the two steel formwork 1s.

[0022] In the above embodiments, the flexible plate 2, the reinforcing plate 3, and the hinge rod 4 work together to form a joint filling and reinforcement structure that can be dynamically adjusted with the steel formwork 1. The flexible plate 2 is elastically fitted between the two steel formworks 1 to form a deformable sealing interface, effectively preventing concrete slurry leakage. The reinforcing plate 3 is embedded in the groove 5 of the steel formwork 1 to provide rigid support and ensure the stability of the joint area. The hinge rod 4 gives the two reinforcing plates 3 relative rotational freedom, allowing the steel formwork 1 to turn horizontally or adapt to the undulations of the foundation vertically. It has good angle adaptability and can meet the construction direction requirements of linear structures such as canals in complex terrain, significantly improving the applicability, flexibility, and engineering application range of the formwork device.

[0023] Specifically, it also includes a through groove 6, a support shaft 7, a rotating block 8, a lock hole 9, and a lock 10. The steel template 1 has through grooves 6 on both sides, which are connected to the groove 5. The support shaft 7 is fixed to the reinforcing plate 3. The rotating block 8 is rotatably connected to the support shaft 7. After rotating, the rotating block 8 can pass through the through groove 6. The steel template 1 has lock holes 9 on both sides of the through groove 6. The lock 10 is slidably connected to the rotating block 8 through a spring 11. The lock 10 cooperates with the lock hole 9.

[0024] In the above embodiments, the tool-free quick assembly and disassembly of the reinforcing plate 3 and the steel template 1 is achieved through the cooperation of the support shaft 7, the rotating block 8, the locking piece 10 and the spring 11. The rotating block 8 rotates after passing through the through groove 6, and the locking piece 10 is tightly locked into the lock hole 9 under the action of the spring 11. When disassembling, it is only necessary to pull the locking piece 10 and rotate it in the opposite direction to separate it, which significantly improves the installation efficiency on the construction site, while ensuring reliable connection and preventing loosening.

[0025] Specifically, the flexible board 2 has inclined surfaces 12 on both sides, and the flexible board 2 is connected and overlapped with the panel of the steel template 1 through the inclined surfaces 12.

[0026] In the above embodiments, inclined surfaces 12 are provided on both sides of the flexible plate 2 to form a smooth transition and overlap with the steel template 1 panel, which reduces the obvious vertical marks at the joint after the concrete has cured, and effectively improves the surface flatness and appearance quality of the inner wall of the water channel.

[0027] Specifically, it also includes an installation groove 13 and an elastic strip 14. The hinge rod 4 has an installation groove 13, and the elastic strip 14 passes through the installation groove 13 and is integrally connected with the flexible plate 2. The elastic strip 14 is located between the two steel templates 1.

[0028] In the above embodiments, an installation groove 13 is provided on the hinge rod 4, through which the elastic strip 14 passes and is integrally connected with the flexible plate 2, and is located between the two steel templates 1. The elastic strip 14 plays a buffering role when the templates rotate relative to each other or are subjected to external force impact, reducing direct collisions with the edges of the steel templates 1, reducing the risk of damage, and thus extending the overall service life of the template device.

[0029] Specifically, it also includes: the thickness of the reinforcing plate 3 is the same as the diameter of the hinge rod 4, and the reinforcing plate 3 is connected to the flexible plate 2 by rivets 15.

[0030] In the above embodiments, the setting of the same thickness ensures that the surface of the flexible plate 2 is relatively flat when it is squeezed by concrete in a horizontal or bent state, thereby improving the flatness of the inner wall after the water channel is formed.

[0031] Specifically, this also includes: the width of the groove 5 is greater than the width of the reinforcing plate 3.

[0032] In the above embodiments, the width of the groove 5 is slightly larger than the width of the reinforcing plate 3, so that the steel templates 1 on both sides can rotate slightly in the vertical direction along the support axis 7 to adapt to the construction environment, such as when the road surface is uneven, the templates need to be adjusted.

[0033] Both the flexible plate 2 and the elastic strip 14 are made of rubber.

[0034] The working principle of this utility model is as follows: During installation, a reinforcing plate 3 is connected to a steel template 1. Rotate the rotating block 8 so that the rotating block 8 can pass through the through slot 6. After the rotating block 8 passes through the through slot 6, pull the locking piece 10, compress the spring 11, rotate the rotating block 8 so that the end of the locking piece 10 is aligned with the lock hole 9, and insert the locking piece 10 into the lock hole 9. To adapt to road surface undulations and the direction of canal pouring, adjust the angle of steel formwork 1 and rotate it along hinge rod 4 or along support axis 7. When dismantling the mold, first pull the locking piece 10 to separate it from the locking hole 9, then rotate the rotating block 8 and align the rotating block 8 with the through groove 6 for quick mold dismantling.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
