Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a lightweight plastic formwork rapid assembly and movement device for cast-in-place concrete structures in water conservancy projects. Background Technology

[0002] Traditional cast-in-place concrete construction in hydraulic engineering suffers from the following pain points:

[0003] Low assembly efficiency of formwork: wooden or steel formwork requires a large number of bolts for fixing, and the installation of a single compartment is time-consuming; Difficult to move: the formwork system is bulky and requires hoisting equipment to assist in relocation, making it impossible to quickly turn around; Poor adaptability: irregular structures (such as arc-shaped spillways and gradient channels) require customized formwork, which is costly and time-consuming; High grout leakage rate: rough joint treatment, frequent honeycomb and pitting on the concrete surface, and increased repair costs.

[0004] Therefore, a lightweight plastic formwork rapid assembly and moving device for cast-in-place concrete structures in water conservancy projects is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight plastic formwork rapid assembly and movement device for cast-in-place concrete structures in water conservancy projects. By setting up a top beam, threaded rods, formwork, and supporting steel pipes, it solves the problems of low formwork assembly efficiency: wooden or steel formwork requires a large number of bolts for fixing, resulting in high installation time per compartment; difficult movement: the formwork system is bulky and requires hoisting equipment for relocation, making rapid turnover impossible; poor adaptability: irregular structures (such as curved spillways and gradual channels) require customized formwork, resulting in high cost and long cycle; high grout leakage rate: rough joint treatment, frequent honeycomb and pitting on the concrete surface, and increased repair costs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a lightweight plastic formwork rapid assembly and moving device for cast-in-place concrete structures in water conservancy projects, including a top beam, with multiple threaded rods welded to the lower surface of the top beam, and formwork sleeves on the surface of each threaded rod. Insertion holes and slots are sequentially opened on both sides of the formwork from top to bottom, and a supporting steel pipe is inserted into the insertion hole.

[0007] Preferably, the lead screw is threaded with a nut, and the lead screw is fixed to the supporting steel pipe by the nut.

[0008] Preferably, both ends of the supporting steel pipe are threaded with positioning nuts, and the surface of the positioning nuts is fixedly connected with knobs.

[0009] Preferably, a card block is inserted into the inside of the card slot, and a handle is fixedly connected to one end of the card block.

[0010] Preferably, both the template and the upper surface of the supporting steel pipe are provided with positioning holes, and the positioning holes are adapted to the lead screw.

[0011] This utility model provides a lightweight plastic formwork rapid assembly and movement device for cast-in-place concrete structures in water conservancy projects, which has the following beneficial effects:

[0012] 1. Lightweight design: The formwork is made of lightweight engineering plastic, which greatly reduces the weight compared to steel formwork, thereby reducing labor and machinery costs during transportation and installation and improving construction efficiency.

[0013] 2. Rapid assembly: The templates are designed with slots and blocks, and together with the supporting steel pipes and threaded rods and the top beam, they are welded into T-shaped supports, which enables the templates to be assembled and supported quickly and accurately, reducing the assembly time on the construction site and shortening the construction cycle.

[0014] 3. Mobility: Multiple formwork panels are integrated by supporting steel pipes, and a mobile support system is formed by connecting the formwork panels to the top beam with screw rods and mounting nuts. This allows the formwork panels to be moved flexibly on the construction site, making it easy to adapt to the needs of different construction locations and improving the flexibility and versatility of the formwork panels.

[0015] 4. Environmentally friendly and energy-saving: Plastic formwork is reusable, reducing the consumption of wood and steel, and meeting environmental protection requirements. At the same time, its production process is relatively simple and has low energy consumption.

[0016] 5. Cost reduction: Due to the high reusability of the template, convenient installation and disassembly, and low transportation costs, the overall cost is significantly reduced compared to traditional templates.

[0017] 6. Good molding quality: low grout leakage rate, small surface flatness error of concrete, meeting the standard of fair-faced concrete. Attached Figure Description

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a lightweight plastic formwork rapid assembly and moving device for cast-in-place concrete structures in water conservancy projects. It includes a top beam 1, with multiple threaded rods 2 welded to the lower surface of the top beam 1. Each threaded rod 2 is fitted with a formwork 3. Insertion holes 4 and slots 5 are sequentially opened on both sides of the formwork 3 from top to bottom. A supporting steel pipe 6 is inserted into the insertion hole 4.

[0028] Template 3 uses lightweight plastic template (PP material, weight ≤10kg / piece), which is lightweight and easy to lift and move. Template 3 is integrated into a whole by supporting steel pipe 6. Compared with traditional templates, the snap-fit ​​connection improves the stability of the overall template 3 and makes it less prone to bending and damage. The top beam 1 and the threaded rod 2 are welded into a T-shaped support according to the side wall size. The welded steel bars are inserted into the template 3 to achieve rapid support.

[0029] The lead screw 2 is threaded with a nut 7, and the lead screw 2 is fixed to the support steel pipe 6 by the nut 7.

[0030] The nut 7 abuts against the supporting steel pipe 6, thereby fixing the position of the top beam 1. The supporting steel pipe 6 supports the overall template 3, reducing the possibility of damage when the template 3 is lifted.

[0031] The two ends of the supporting steel pipe 6 are threaded with positioning nuts 8, and the surface of the positioning nuts 8 is fixedly connected with knobs 9.

[0032] The position of the support steel pipe 6 is maintained by the positioning nut 8 to prevent displacement of the lifting or moving support steel pipe 6, which could cause the lead screw 2 to bend and become unusable.

[0033] A card block 10 is inserted into the inside of the card slot 5, and a handle 11 is fixedly connected to one end of the card block 10.

[0034] The upper surfaces of both the template 3 and the supporting steel pipe 6 are provided with positioning holes 12, which are compatible with the lead screw 2.

[0035] Specifically, the lightweight plastic formwork rapid assembly and movement device for cast-in-place concrete structures in water conservancy projects operates as follows: Based on the size requirements of the concrete structure, select an appropriate number and specifications of formwork 3. Perform initial assembly on the construction site ground, aligning the clips 10 of formwork 3 with the slots 5 of adjacent formwork 3, and sequentially fastening them to form formwork units. Use supporting steel pipes 6 to determine the accurate position between formwork units, and then tighten them with positioning nuts 8 to achieve rapid assembly. Utilize the supporting steel pipes 6 to form a grid support frame for overall lifting and movement. Weld the top beam 1 and threaded rod 2 according to the side wall dimensions to form a T-shaped support. Insert the threaded rod 2 into the formwork 3 for rapid support. After the concrete is poured and reaches a certain strength, loosen the nuts 7 and positioning nuts 8, manually remove the supporting steel pipes 6, and use a small hammer to remove the top T-shaped support, unloading the formwork 3 from the concrete surface for the next assembly and use. Since the formwork 3 is relatively lightweight, 1-2 workers can move it horizontally. If upward movement is required, a small hoist is used for lifting.

[0036] 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.
