Early-dismantling levelling jacking for concrete structure formwork

Abstract

The invention provides an early-dismantling levelling jacking for a concrete structure formwork. The early-dismantling levelling jacking comprises a threaded rod, a bracket, a movable plate, a round sphere ring, two adjusting nuts and an early-dismantling support; the movable plate is arranged on the bracket; the bracket comprises a support plate and a short cylinder, the interior of the short cylinder is in the shape of a hemispherical bowl surface, one end of the short cylinder is fixedly connected with the bottom surface of the support plate, the spherical radius of the round sphere ring surface in the round sphere ring is the same as that of the hemispherical bowl surface in the short cylinder, the size of the round sphere ring is matched with that of the short cylinder, and the short cylinder and the round sphere ring are fixedly arranged up and down; the top of the threaded rod is fixedly connected with a round sphere, the sphere radius of the round sphere is matched with the spherical radius of the hemispherical bowl surface in the short cylinder, and the threaded rod is in spherical hinged connection with the bracket through the limit of the round sphere ring. According to the early-dismantling levelling jacking for the concrete structure formwork, jacking levelling of a formwork supporting system can be achieved, and the construction quality of the concrete structure surface at the jacking position can be guaranteed.

Description

technical field [0001] The invention relates to a jacking bracket for formwork engineering support in concrete structure construction, in particular to an adjustable flat jacking bracket for early demolition of a concrete structure formwork. Background technique [0002] Such as figure 1 As shown, in the construction of existing construction projects, in the support system of early demolition of concrete structure formwork, the commonly used early demolition adjustable jacking bracket is welded and fixed by the screw rod 1′ and the supporting plate 2′, and the early demolition bracket 3′ Set on the screw rod, when the formwork is supported and arranged, the installation of the supporting steel pipe vertical rod 4' is not vertical due to construction human errors, resulting in the early removal of the supporting plate 2' of the adjustable jacking bracket. 'The concrete surface is uneven, affecting the quality of concrete perception. [0003] Disclosed in the prior art is a ...
