Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a novel non-disassembly membrane shell structure for concrete casting. Background Art

[0002] In the traditional formwork pouring process of structural columns and beams, wooden or metal formwork is often used for formwork, and these formworks are removed after the concrete solidifies. This method has some disadvantages:

[0003] Time-consuming and labor-intensive: Traditional formwork requires additional installation and removal steps, which increases the time and labor costs of the project. Manual formwork removal is not only time-consuming and labor-intensive, but may also damage the formwork, increasing the cost of maintenance and replacement of the formwork.

[0004] Insufficient structural connectivity: Traditional formwork may leave marks or gaps after removal, which may lead to insufficient connectivity in the concrete structure. This may lead to structural weaknesses and damage, and require additional reinforcement and repair work during use.

[0005] Material waste and increased costs: Traditional formwork may be damaged after removal and cannot be reused, resulting in material waste. In addition, the production and maintenance of these formworks themselves also require certain costs.

[0006] Therefore, this invention proposes a novel membrane shell structure for concrete casting without disassembly to solve the above problems. Utility Model Content

[0007] In order to overcome the defects of the prior art, the utility model aims to provide a novel non-disassembly membrane shell structure for concrete casting.

[0008] To achieve the above object, the technical solution of the utility model is implemented as follows: a novel non-disassembly membrane shell structure for concrete casting, comprising a non-disassembly membrane shell, wherein the non-disassembly membrane shell is composed of two U-shaped membrane shells with the same length, width and height, and a steel mesh, a galvanized flat steel mesh, an anchoring tie and a bolt sleeve are arranged inside the inner cavity of the U-shaped membrane shell, and high-strength concrete is poured in the inner cavity of the U-shaped membrane shell;

[0009] A plurality of anchoring protrusions are evenly arranged on the inner shell wall of the U-shaped membrane shell;

[0010] The steel mesh is U-shaped and integrated, and is laid in a designated U-shaped membrane shell mold, and the galvanized flat steel mesh is laid inside the steel mesh;

[0011] The galvanized flat steel mesh and the steel mesh are bound and fixed by steel wire.

[0012] Preferably, a plurality of the anchoring anchors and the bolt sleeves are equidistantly installed at designated positions of the steel mesh, and an outer end of the anchoring anchor passes through the interior of the U-shaped membrane shell.

[0013] The beneficial effects of the utility model are embodied in:

[0014] Stable and reliable structure: The structure is composed of two identical U-shaped membrane shells, with steel mesh, galvanized flat steel mesh, anchoring parts and bolt sleeves set inside, and the internal cavity is poured with high-strength concrete. This design ensures that the formed non-disassembly membrane shell has good firmness and stability after the concrete solidifies, enhances the connection stability of the structure, and reduces the displacement and looseness between components.

[0015] Easy to operate and no need to remove the formwork: There is no need to remove the formwork, it has good stability and is easy to install. It can be directly used for the casting and forming of house structural columns and structural beams, and it can be integrated with the cast-in-place concrete, saving construction time and construction costs.

[0016] Improve structural connectivity: The added anchoring protrusions and the design of the anchoring tie pieces make the non-dismantling membrane shell and the poured concrete structure form a tighter connection, ensuring that after the concrete solidifies, the non-dismantling membrane shell and the internal concrete form a whole. This structure further improves the stability and bearing capacity of the overall structure.

[0017] In general, this new type of membrane shell structure for concrete casting and molding improves structural stability and construction efficiency by optimizing the design and construction process, while optimizing material usage. The absence of mold removal can save construction time and construction costs, providing an innovative solution with broad application prospects for the construction industry.
