Description

Technical Field

[0001] The utility model relates to the technical field of formwork supports, and specifically relates to an exterior basement wall formwork. Background Technique

[0002] When constructing the exterior basement wall, it is necessary to use a support formwork to support building materials. After the building wall is shaped, the support formwork is removed.

[0003] A Chinese patent discloses an exterior basement wall formwork system with the publication number CN208907304U, which includes: an exterior wall formwork, a formwork support, a water-stop tie rod, an inner inclined strut, a wooden square, and an outer inclined strut; the exterior wall formwork includes an inner formwork and an outer formwork arranged adjacent to each other; the formwork support includes a transverse main keel and a vertical secondary keel connected perpendicular to each other; the water-stop tie rod is connected between the inner formwork and the outer formwork; one end of the inner inclined strut is connected to the formwork support corresponding to the inner formwork, and the lower end of the inner inclined strut is connected to a pre-embedded steel bar ring; the pre-embedded steel bar ring is arranged below the upper steel mesh of the concrete slab and is jointly embedded in the concrete; the wooden square is arranged on the outer foundation pit slope protection; one end of the outer inclined strut is connected to the formwork support corresponding to the outer formwork, and the lower end of the outer inclined strut is supported on the wooden square through a jack. The exterior basement wall formwork system of the utility model can achieve stable support on both the inside and outside, so the fixation of the exterior wall formwork is very firm, which is convenient for the concrete pouring construction.

[0004] However, it still has the following disadvantages: The device uses wooden squares and inclined struts to support the formwork. However, when there is an error in the installation position of the wooden squares, the length of the inclined struts cannot be adjusted, which may cause the formwork to tilt and affect the construction quality of the exterior wall. For this reason, we propose an exterior basement wall formwork to solve this problem. Content of the Utility Model
