Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to an adjustable template inner support fixing device. Background Art

[0002] The internal support method of the formwork usually refers to a support structure method used in construction or engineering to support the formwork (i.e., a temporary support structure for pouring concrete) to ensure that the concrete can maintain the required shape and stability during construction. Common internal support methods of the formwork include: Steel pipe support: Use steel pipes as support columns, and set up a steel pipe support system inside the formwork to support the formwork during concrete pouring. Wooden support: Use wooden support components (such as wooden beams, wooden columns, etc.) to support the formwork. This method is often used in simple building structures or temporary engineering projects. Support: Set a support support at the bottom of the formwork, and support the formwork by adjusting the height of the support so that it can withstand the weight and pressure of concrete. Reinforced concrete support: When pouring concrete, use reinforced concrete components (such as beams, columns, etc.) as a supporting structure to support the formwork and at the same time serve as part of the concrete component. Scaffolding support: Build a scaffolding structure around the formwork, and use the scaffolding to support the formwork to ensure that construction workers can safely install the formwork and pour concrete. These support methods are selected and used according to specific construction needs and engineering conditions to ensure safety, stability and efficiency during the construction process.

[0003] In Chinese utility model CN218438283U, "an internal support device for concrete wall formwork for construction" is proposed.
