The invention provides a form structure for concrete construction, comprising a plurality of mutually connected form units, connectors for connecting the adjacent form units and peripheral supports for supporting the form units; each form unit comprises a front form and a reinforcing plate component arranged at the rear of the front form, a front projection of the reinforcing plate component on the rear face of the front form is not greater than the front face of the rear form in area, and the front face of the front form is also provided with a hardened press film layer that may cover the front face of the front form. By providing the hardened press film layer on the front face of each front forms, it is possible to improve the smoothness of the faces of the front forms in contact with concrete, it is possible to effectively reduce adhesion chances of concrete with the front forms, tightness of outermost concrete is improved, and cellular pitted surface is avoided; in addition, the hardened press film layers are high in hardness, the structure is safe and reliable in use, damage rarely occurs, and the gloss of the outer layer of a concrete wall is further improved.
Description
technical field [0001] The invention belongs to the technical field of concrete construction, and more specifically relates to a formwork structure for concrete construction. Background technique [0002] The substation is an important part that directly affects the safety and economy of the entire power system. It is the intermediate link between the power plant and the user, and plays the role of transforming and distributing electric energy. The 500kV substation is the main component. The 500kV firewall in the 500kV substation generally adopts the structure filling type, and its firewall adopts the concrete structure form of reinforced concrete pouring. The existing formwork structure for concrete pouring construction of the firewall generally adopts three-ply board or ordinary box board, and the outside of the wall at the pouring place There are honeycomb pitted surfaces on the surface, and the finish is poor, which affects the quality of the wall. Contents of the inve...
