Upright post formwork

Abstract

The invention relates to an upright post formwork. The upright post formwork comprises four steel formwork bodies and a plurality of fasteners, wherein the fasteners hoop outside the four steel formwork bodies and are arranged in the height direction of the steel formwork bodies, and the adjacent steel formwork bodies are connected by connecting columns with square cross sections; clamping tables extending vertically and outwardly are correspondingly arranged on the side walls of the two sides, correspondingly opposite to the adjacent steel formwork bodies, of the connecting columns, clamping grooves for the clamping tables to be clamped are formed in the positions, opposite to the clamping tables, of the side walls of the sides, opposite to the connecting columns, of the steel formwork bodies, and the shapes of the clamping grooves are matched with the shapes of the clamping tables; a plurality of perforations are formed in the positions, opposite to the clamping grooves, of the outer side surfaces of the steel formwork bodies in the height direction of the steel formwork bodies, and inserting holes which are formed opposite to the perforations in a one-to-one mode are formed in the clamping tables; and the steel formwork bodies are provided with plug pins with the number being matched with the number of the perforations, and the plug pins penetrate through the perforations and are inserted into the inserting holes. The upright post formwork has the advantages that the sealability of the joints of the adjacent steel formwork bodies is ensured, and thus the occurrence of the situation of mud leakage between the adjacent steel formwork bodies is avoided.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a column formwork. Background technique [0002] In construction, the existing column construction is generally to build the column formwork first, and then pour the concrete. The column formwork is generally composed of multiple steel formworks to form the shape of the required column. The formwork is fixed together, because the mass of the steel formwork is relatively large, it is more complicated to fix, especially the bolts are difficult to accurately align the bolt mounting holes on the two formwork bodies. [0003] When pouring concrete into the column formwork, the concrete at the bottom of the column flows towards the formwork due to gravity, and as the concrete is continuously poured into the column formwork, the concrete at the bottom end exerts a thrust on the column formwork due to deposition , with the continuous increase of concrete and the continu...

[0002] In construction, the existing column construction is generally to build the column formwork first, and then pour the concrete. The column formwork is generally composed of multiple steel formworks to form the shape of the required column. The formwork is fixed together, because the quality of the steel formwork is relatively large, it is more complicated to fix, especially the bolts are difficult to accurately align the bolt mounting holes on the two formwork bodies

[0003] When pouring concrete into the column formwork, the concrete at the bottom of the column flows towards the formwork due to gravity, and as the concrete is continuously poured into the column formwork, the concrete at the bottom end exerts a thrust on the column formwork due to deposition , with the continuous increase of concrete and the continuous increase of thrust, it is easy to deform and damage the adjacent bottom end, resulting in grout leakage
