Description

Technical Field

[0001] This utility model relates to the technical field of plastic steel formwork, and in particular to a plastic steel formwork for water conservancy projects. Background Technology

[0002] In water conservancy projects, such as the construction of concrete structures like riverbank protection, sluice gates, and spillways, formwork engineering is a crucial step. The performance of the formwork directly affects the molding quality of concrete components, construction efficiency, and project costs.

[0003] Currently, the most commonly used formwork in water conservancy projects is steel formwork and wooden formwork. Steel formwork has the advantages of high strength, high rigidity, and high reusability, but it is heavy, inconvenient to transport and install, and highly dependent on construction machinery. In addition, in humid, electrolyte-rich water conservancy environments, steel formwork is extremely prone to corrosion, which not only affects the appearance of the concrete surface but also greatly shortens the service life of the formwork. Although wooden formwork is lightweight and easy to process, it has low strength, is prone to water absorption and deformation, and is prone to warping and damage after repeated use. It has a low reusability and consumes a lot of timber resources, which does not conform to the concept of green construction.

[0004] In recent years, some plastic or composite formwork has emerged in an attempt to address the aforementioned shortcomings of steel and wood formwork. However, existing plastic formwork generally suffers from insufficient overall strength and rigidity, making it prone to deformation when subjected to the lateral pressure of concrete in large-scale hydraulic engineering projects, thus affecting the dimensional accuracy of the structure. Furthermore, the connection methods between existing formwork panels are often cumbersome, resulting in inefficient installation and dismantling, and increasing construction time and labor costs.

[0005] Furthermore, water conservancy projects face complex construction environments, especially in cold northern regions where there are large temperature differences between day and night. Existing plastic formwork becomes brittle in low-temperature environments, and internal moisture freezing can easily cause frost heave and cracking, leading to premature damage and failing to meet durability requirements. Utility Model Content

[0006] This utility model aims to address the shortcomings of existing technologies by providing a plastic steel formwork for water conservancy projects.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] A type of plastic-steel formwork for water conservancy projects includes a plastic sheet. The left and right sides of the back of the plastic sheet are symmetrically provided with L-shaped connecting seats. The two L-shaped connecting seats on the mating surfaces of the two plastic sheets are connected and fixed by bolt clamping assemblies. Several reinforcing steel plates are provided inside the plastic sheet. Anti-freezing and crack tracing heat is provided inside the plastic sheet and outside the reinforcing steel plates. The two ends of the anti-freezing and crack tracing heat are connected to connecting wires, and the connecting wires pass through the top of the plastic sheet.

[0009] The bolt clamp assembly includes two U-shaped clamping plates. One side plate of the U-shaped clamping plate passes through the space between the L-shaped connecting seat and the plastic plate. The center plates of the two U-shaped clamping plates are fixed together by bolts and nuts.

[0010] A rotating handle is provided on the side wall of the nut.

[0011] The reinforcing steel plate has a "Z" shaped structure.

[0012] The bottom of the plastic sheet has a serrated structure.

[0013] The plastic panel has a hanging ring at the top.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] like Figures 1 to 4 As shown, a plastic-steel formwork for water conservancy projects includes a plastic sheet 1, an L-shaped connecting seat 2, a bolt clamp assembly 3, a reinforcing steel plate 4, a frost-resistant heat tracing cable 5, a connecting wire 6, and a serrated structure 7.

[0027] The plastic board 1 contains several reinforcing steel plates 4. The plastic board 1 is the main body, and several reinforcing steel plates 4 are embedded inside to form a "plastic-steel" composite structure. While ensuring lightweight, the strength and rigidity of the template are greatly improved.

[0028] The reinforced steel plate 4 has a "Z" shaped structure, which enhances the bending resistance of the template.

[0029] The plastic plate 1 has symmetrical L-shaped connecting seats 2 on the left and right sides of its back. The two L-shaped connecting seats 2 on the mating surfaces of the two plastic plates 1 are connected and fixed by bolt clamping assembly 3.

[0030] The bolt holder assembly 3 includes two U-shaped clamping plates 31. One side plate of the U-shaped clamping plate 31 passes through the space between the L-shaped connecting seat 2 and the plastic plate 1. The center plates of the two U-shaped clamping plates 31 are fixed together by bolts 32 and nuts 33. The nut 33 has a rotating handle 34 on its side wall, so that the tightening and loosening of the nut 33 does not require additional tools, realizing quick assembly and disassembly.

[0031] A quick and secure connection between panels is achieved through a unique L-shaped connector 2 and bolt clamp assembly 3. This connection method is easy to operate, provides high connection strength, and ensures the overall stability of the template system.

[0032] The plastic sheet 1 is equipped with a frost-resistant heat tracing cable 5 on the outer periphery of the reinforcing steel plate 4. The two ends of the frost-resistant heat tracing cable 5 are connected to connecting wires 6, and the connecting wires 6 extend out of the top of the plastic sheet 1.

[0033] An anti-freeze-crack heating cable 5 is built into the outer perimeter of the reinforcing steel plate 4 and led out through a connecting wire 6. It can be electrically heated in low-temperature environments to prevent the plastic from cracking due to freezing expansion, greatly improving the service life and adaptability of the template in cold regions.

[0034] The bottom of the plastic plate 1 has a serrated structure 7. This facilitates better integration with the ground or other structures during installation and improves grip.

[0035] The top of the plastic panel 1 is equipped with lifting rings, which facilitates the handling and hoisting of the template.

[0036] This utility model of plastic steel formwork integrates the advantages of lightweight, high strength, easy installation, and frost resistance. It is particularly suitable for water conservancy engineering construction scenarios with complex environments and demanding requirements, and effectively solves the problems of traditional steel formwork being heavy, easily corroded, and wooden formwork being easily deformed and having a short lifespan.

[0037] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
