Description

Technical Field

[0001] The utility model belongs to the technical field of shear wall formwork, in particular to a back rib supporting structure for shear wall formwork. Background Art

[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, refers to the wall in a house or structure that mainly bears the horizontal load and vertical load gravity caused by wind load or earthquake, and is used to prevent structural shear damage.

[0003] In the field of traditional housing construction projects, shear wall formwork usually adopts traditional wooden formwork, which is easy to be affected by moisture and deformation during construction, resulting in uneven formwork and unusable formwork, thus affecting the construction quality. During use, it is often corroded by chemical substances such as cement, causing the formwork surface to age and crack, and it cannot be used again. After multiple turnovers, it has a great impact on the construction and component molding quality. In terms of environmental protection, wooden formwork has a low turnover rate and poor reuse capacity, which does not conform to the current energy-saving and environmentally friendly construction concept. In response to the above technical problems, a plastic-coated formwork with ribs is used for shear wall formwork. For example, the prior art discloses a utility model patent named Adjustable Formwork Unit for Curved Shear Wall and Adjustable Formwork for Curved Shear Wall (Authorization Announcement No.: CN216142396U).

[0004] The surface of the plastic-coated formwork is relatively smooth and is not easy to bond with concrete. Without the use of a release agent, it can still achieve the visual quality of fair-faced concrete. At the same time, the plastic-wood combination is assembled with special pins, and the formed shear wall has good flatness, which can achieve a plaster-free effect.

[0005] In order to improve the force-bearing capacity of the plastic-coated formwork, it is necessary to set a supporting structure between the back ribs in the horizontal direction. For example, the prior art discloses an invention patent named a back rib structure common to both internal and external corners and a method of using the same (application publication number: CN117759020A). When the structure is used, one connecting column is clamped by a hook head, and the other connecting column is clamped by a clamp.

[0006] When pouring concrete in the formwork, the plastic-coated formwork is subjected to a large force. How to prevent the back rib support structure from falling off the back rib is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
