Description

Technical Field

[0001] This utility model relates to the field of concrete formwork technology, specifically a concrete formwork reinforcement device for water conservancy projects. Background Technology

[0002] In water conservancy engineering construction, concrete pouring is a key process for forming the main structure of hydraulic structures; as the forming carrier of concrete, the reliability of the formwork and its reinforcement device is directly related to the dimensional accuracy, surface quality and construction safety of the poured body.

[0003] According to CN221073500U, a large-volume concrete reinforcement device is disclosed. This technology discloses a technical solution including "a reinforcement frame covering the concrete formwork, a first threaded hole on the reinforcement frame, a first bolt threaded into the first threaded hole, one end of the first bolt abutting against the corresponding side plate of the concrete formwork, and the reinforcement frame being assembled from several reinforcement plates by assembly components". It has the technical effect that "by setting the reinforcement plates and the first bolt, it is possible to reinforce the concrete formwork from the outside. Compared with the existing method of using tie bolts inside the concrete beam for reinforcement, this utility model will not affect the final formed concrete structure and appearance".

[0004] In existing water conservancy project formwork construction, tie rods or welding are often used to reinforce the formwork. However, during repeated use, the exposed threaded sections or connection parts are easily penetrated and encased by cement slurry during concrete pouring. Because the cement slurry has high strength and tight adhesion after hardening, the encased threads are often difficult to rotate, leading to disassembly difficulties. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete formwork reinforcement device for hydraulic engineering. By uniformly applying clamping force through the reinforcement components, it resists the lateral pressure of concrete and prevents formwork deformation and bulging. Furthermore, the reinforcement components can isolate cement, prevent thread jamming, and improve durability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete formwork reinforcement device for water conservancy projects, comprising a base, on which a mold mechanism is provided for concrete pouring and molding, the mold mechanism comprising:

[0007] The template assembly includes a base plate fixed to the top of the base, side plates on both the left and right sides of the base plate, and baffles fixed to the front and rear ends of the top of the base.

[0008] The reinforcement component includes a cylinder positioned between the left and right locking lugs. A left hook is fixed to the left end of the cylinder, and a nut is rotatably installed on the outer wall of the right end of the cylinder. A threaded rod is slidably installed through the right end of the cylinder and threadedly installed with the nut. A right hook is fixed to the right end of the threaded rod, and a folded flexible hose is rotatably installed on the right end of the nut, with the right end of the folded flexible hose fixed to the right end of the threaded rod.

[0009] Preferably, the reinforcing component further includes a concave groove formed on the outer wall of the threaded rod, and an internal hexagon bolt is threaded onto the cylinder, with the inner end of the internal hexagon bolt located inside the concave groove.

[0010] Preferably, the template assembly further includes several locking lugs fixed to the top of the side plate and arranged in a front-to-back manner, with locking holes provided inside the locking lugs.

[0011] Preferably, the template assembly further includes shaft seats fixed at the left and right ends of the base, and a shaft bracket is fixed at the bottom of the side plate and pivotally connected to the shaft seats.

[0012] Preferably, the template assembly further includes several reinforcing ribs arranged front to back inside the base, and several reinforcing ribs arranged front to back are fixed inside the side plate.

[0013] Preferably, the template assembly further includes a reinforcing frame fixed between the top of the base and the baffle.

[0014] Beneficial effects

[0015] This utility model provides a concrete formwork reinforcement device for hydraulic engineering. Compared with the prior art, it has the following advantages:

[0016] 1. By rotating the nut, the threaded rod is driven to extend and retract linearly, thereby adjusting the distance between the left and right hooks. This pulls the side plates on both sides towards the center, making the entire template assembly firmly combined into a rigid closed cavity that can withstand the huge lateral pressure of concrete, preventing bulging and deformation. Furthermore, the folded flexible hose deforms synchronously with the extension and retraction of the threaded rod, completely wrapping and protecting the exposed threaded section, preventing cement slurry intrusion and solidification, avoiding thread jamming, and improving the durability and reusability of the device.

[0017] 2. By setting several locking lugs at intervals along the front and back direction on the top edge of the side plate, and directly hooking or connecting the left and right hooks at both ends of the reinforcing component to the locking holes, the strong axial tensile force generated by the reinforcing component when tensioned is evenly transmitted to the entire stress surface of the side plate through these evenly arranged reinforcing points; avoiding stress concentration, preventing the side plate from bulging or deforming due to excessive local stress, and ensuring the accuracy of the dimensions and surface flatness of the cast body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a concrete formwork reinforcement device for water conservancy projects, including a base 1, on which a mold mechanism 2 is provided for concrete pouring and molding. The mold mechanism 2 includes:

[0026] The template assembly 21 includes a base plate 211 fixed to the top of the base 1, side plates 212 on both the left and right sides of the base plate 211, and baffles 213 fixed to the front and rear ends of the top of the base 1.

[0027] The reinforcement component 22 includes a cylinder 221 disposed between the left and right locking lugs 214. A left hook 222 is fixed to the left end of the cylinder 221. A nut 223 is rotatably installed on the outer wall of the right end of the cylinder 221. A threaded rod 224 is slidably installed through the right end of the cylinder 221 and threadedly installed with the nut 223. A right hook 225 is fixed to the right end of the threaded rod 224. A folded hose 228 is rotatably installed on the right end of the nut 223, and the right end of the folded hose 228 is fixed to the right end of the threaded rod 224.

[0028] In this embodiment, rotating the nut 223 drives the threaded rod 224 to extend and retract linearly, thereby adjusting the distance between the left hook 222 and the right hook 225. This pulls the side plates 212 on both sides towards the center, making the entire template assembly 21 firmly combined into a rigid closed cavity that can withstand the huge lateral pressure of concrete, preventing bulging and deformation. Furthermore, the folded hose 228 deforms synchronously with the extension and retraction of the threaded rod 224, completely wrapping and protecting the exposed threaded section, preventing the intrusion and solidification of cement slurry, avoiding thread jamming, and improving the durability and reusability of the device.

[0029] Specifically, the reinforcing component 22 also includes a recessed groove 226 formed on the outer wall of the threaded rod 224, and an internal hexagon bolt 227 is threaded on the cylinder 221, with the inner end of the internal hexagon bolt 227 located inside the recessed groove 226.

[0030] In this embodiment, when the nut 223 is rotated, the threaded rod 224 that is threaded with it cannot rotate with the nut 223 because the concave groove 226 on its outer wall is restricted by the end of the internal hexagon bolt 227 embedded in the groove. This forces the rotational motion of the nut 223 into a pure axial linear motion of the threaded rod 224 relative to the cylinder 221.

[0031] Specifically, the template component 21 also includes several locking lugs 214 fixed to the top of the side plate 212 and arranged in front and behind, with locking holes 215 inside the locking lugs 214.

[0032] In this embodiment, by providing a number of locking lugs 214 at intervals along the front-back direction of the top edge of the side plate 212, and by directly hooking or connecting the left hook head 222 and the right hook head 225 at both ends of the reinforcing component 22 to the locking hole 215, the strong axial tensile force generated by the reinforcing component 22 when tensioned is evenly transmitted to the entire stress surface of the side plate 212 through these evenly arranged reinforcing points; thus avoiding stress concentration and preventing the side plate 212 from bulging or deforming due to excessive local stress, ensuring the accuracy of the dimensions and the flatness of the surface of the cast body.

[0033] Specifically, the template assembly 21 also includes shaft seats 216 fixed at the left and right ends of the base 1, and a shaft bracket 217 fixed at the bottom of the side plate 212 and pivotally connected to the shaft seat 216.

[0034] In this embodiment, by precisely embedding the shaft bracket 217 fixed to the bottom of the side plate 212 into the shaft seats 216 at both ends of the base 1, a stable pivot connection is formed, which allows the side plate 212 to rotate. When mold closing is required, it can be rotated inward to the vertical working position and locked by the reinforcing component 22. After the casting is completed and the reinforcing component 22 is removed, it can be easily rotated outward to open.

[0035] Specifically, the template component 21 also includes several reinforcing ribs 218 fixed inside the base 1 and arranged in a front-to-back manner, and several reinforcing ribs 219 fixed inside the side plate 212 and arranged in a front-to-back manner.

[0036] In this embodiment, the rigid skeleton of the template is formed by the reinforcing ribs 218 arranged inside the base 1 and the reinforcing ribs 219 inside the side plate 212; the structural rigidity of the base 1 and the side plate 212 is improved, effectively resisting concrete load and preventing the template from bending and deforming during the pouring process, thereby ensuring the dimensional accuracy and surface flatness of the formed component.

[0037] Specifically, the template assembly 21 also includes a reinforcing frame 2110 fixed between the top of the base 1 and the baffle 213.

[0038] In this embodiment, the reinforcing frame 2110 effectively transmits and disperses the lateral thrust acting on the baffle 213 during concrete pouring to the solid base 1, thereby enhancing the baffle 213's resistance to overturning and displacement.

[0039] The working principle and usage process of this utility model are as follows: First, the operator rotates the side plates 212 on both sides inward around the pivot formed by the shaft frame 217 at its bottom and the shaft seat 216 on the base 1, so that they stand upright and close with the base plate 211 and the baffles 213 at the front and rear ends to form a mold cavity to be reinforced; at this time, the locking lugs 214 arranged at the front and rear of the top of the side plates 212 and the locking holes 215 thereon are exposed, serving as key force anchor points; then, the reinforcement component 22 is placed between the locking lugs 214 on the left and right sides, so that the left hook head 222 and the right hook head 225 respectively hook into the corresponding locking holes 215;

[0040] Then, using a tool, rotate the nut 223 clockwise. Because the concave groove 226 on the threaded rod 224 is restricted by the end of the internal hex bolt 227, the threaded rod 224 cannot rotate and can only retract linearly into the cylinder 221 under the drive of the nut 223. This movement shortens the effective distance between the left and right hooks, thereby generating a strong force pulling towards the center on the side plates 212 on both sides, and finally locking all the template components into a rigid whole that can resist the lateral pressure of concrete.

[0041] During this process, the folded hose 228 deforms synchronously with the extension and retraction of the threaded rod 224, always tightly wrapping the threaded section to effectively prevent cement slurry from entering. After the pouring is completed and the concrete has solidified, the nut 223 is loosened counterclockwise to extend the threaded rod 224, releasing the tension on the side plate 212. The reinforcing component 22 can then be easily removed. Finally, the side plate 212 is pivoted outward to open it, allowing the molded component to be removed, thus completing the entire cycle.
