Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to the technical field of small pipe trench core molds, and specifically refers to a foldable and expandable electric core mold for a small pipe trench. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.

[0003] A pipe trench, also called a common trench for underground pipelines, is an intensive and integrated municipal utility infrastructure that can accommodate two or more municipal utility pipelines (including water supply, recycled water, heat, electricity, telecommunications, etc.). During construction, small pipe trenches are often encountered. Small pipe trenches usually use 15mm thick wooden formwork as the core formwork, and short steel pipes are used to support the wooden formwork to provide reinforcement and support.

[0004] However, the above approach has the following disadvantages:

[0005] 1. The internal space of the small pipe trench is small, and there is insufficient space for supporting wooden formwork;

[0006] 2. A large number of steel pipe supports are required;

[0007] 3. When removing the mold, the steel pipe is difficult to remove due to the small space inside the trench;

[0008] 4. When removing the formwork, the formwork cannot be removed directly by arms because the internal space of the trench is small and long. Steel bars and crowbars are used to remove the damaged formwork and the formed concrete structure;

[0009] 5. The dismantled formwork cannot be reused, resulting in a waste of resources.

[0010] Therefore, it is hoped to provide a small pipe trench core mold, which is simple and convenient to install and disassemble, reduces the construction difficulty, speeds up the construction progress, and reduces the construction cost. Utility Model Content

The rotation direction of the crank is opposite to the rotation direction during the above-mentioned unfolding. After the template is folded, it is separated from the concrete structure to achieve the form removal effect, similar to Figure 3 shown, and the present utility model can be reused subsequently.

[0062] Compared with the prior art, the utility model has the following advantages and effects:

[0063] 1. No steel pipe support is required;

[0064] 2. The curved arm folding motor is adopted, with high construction efficiency and few personnel requirements;

[0065] 3. Electric control is adopted during support, which is safe, fast and efficient;

[0066] 4. Electric control is adopted during form removal, and the formwork can be easily removed;

[0067] 5. The removed formwork can be reused multiple times, meeting the requirements of green construction and solving the difficulty of form removal in a small space.

[0068] Therefore, by adopting the utility model, the unfolding and folding of each formwork are controlled by a curved arm folding motor, solving the problems of difficult installation and removal of the internal core formwork in a small trench, reducing the input of labor and materials, and increasing the construction efficiency and mechanization.

[0069] In summary, the foldable and unfoldable electric core formwork for the small trench of the utility model is simple and convenient to install and disassemble, reduces the construction difficulty, speeds up the construction progress, reduces the construction cost, is ingeniously designed, has a simple structure, is easy to manufacture, has a low manufacturing cost, and is suitable for large-scale popularization and application.

[0070] Thus, the purpose of the utility model has been fully and effectively achieved. The function and structural principle of the utility model have been shown and described in the embodiments, and the implementation mode can be modified arbitrarily without departing from the principle. Therefore, the utility model includes all deformation implementation modes based on the spirit and scope of the claims.
