Concrete formwork combining and flatness adjusting structure

Abstract

The invention discloses a concrete formwork combining and flatness adjusting structure and belongs to the field of buildings. Fixing mechanisms are arranged at backs of formworks, grooves and / or bulges are arranged on end surfaces of the formworks, opposite adjusting bolts are arranged in formworks perpendicular to end surfaces of butt-jointed formworks, adjusting bolt combining parts are connected between the adjusting bolts, notches with thickness smaller than that of formworks are arranged near butt-jointed edges at backs of the formworks, a mixed formwork comprises a wooden formwork arranged between a pair of steel formworks, steps are arranged on end surfaces of opposite steel formworks, the two ends of the wooden formwork are arranged on the steps, and lower end surfaces of the stepsare in threaded connection with long adjusting bolts and adjusting bolt combining parts. The structure can guarantee smoothness and flatness of concrete surfaces, prevent loss of concrete slurry, improve formwork combination speed and combination quality, guarantee concrete casting quality and improve construction quality.

Description

technical field [0001] The invention relates to a concrete formwork structure, in particular to a concrete formwork combination and flatness adjustment structure, which belongs to the construction field. Background technique [0002] The building formwork structure used in the construction of cast-in-place concrete structures is mainly composed of three parts: panels, support structures and connectors. The panel is the load-bearing slab that directly contacts the freshly poured concrete; the support structure is a temporary structure that supports the panel, concrete and construction loads, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is the connection between the panel and the support Fittings that connect structures into a whole. [0003] Building formwork can be divided into combined steel formwork and wooden formwork according to the nature of the material. Combined steel formwork is a new type of formwor...

Problems solved by technology

[0008] In view of the phenomenon that the surface of the concrete formwork will be misaligned during the construction process, the formwork will be bent, the end face of the formwork will be too large, and the loss of slurry will cause the surface of the concrete to have poor flatness and poor quality. The construction is difficult and the flatness is difficult to control due to reasons such as unequal thickness. The invention provides a concrete formwork combination and a flatness adjustment structure. The purpose is to ensure the smoothness of the concrete surface and prevent the loss of concrete slurry. , improve the combination speed and quality of formwork, ensure the quality of concrete pouring, and improve the quality of construction
