Formwork supporting structure of concrete cast-in-place construction

Abstract

The invention discloses a formwork supporting structure of concrete cast-in-place construction. The formwork supporting structure of the concrete cast-in-place construction comprises a long supportingrod, a short supporting rod and a base. The base is slidably connected to at least one lower end of the long supporting rod and the short supporting rod, connecting pieces used for connecting a longitudinal beam arranged on a formwork are arranged at the upper ends of the long supporting rod and the short supporting rod, at least one connecting piece is adjustably connected with the longitudinalbeam, the long supporting rod and the short supporting rod are telescopic structures, and the base is fixedly connected with the lower end of the long supporting rod through a fine adjustment piece. The lengths of the supporting rods are adjusted by adjusting pin clamping buckles in different adjusting holes, then the lower ends of the supporting rods are adjusted inwards and outwards in a movingmode, a sliding block arranged at the lower end of supporting rods is pushed by a push rod of a jack to move inwards in a sliding groove formed in the base to a proper position and is fixed, the tensioning effect of the supporting rods is further improved by adjusting the fine adjustment piece.

Description

technical field [0001] The invention relates to a formwork support structure, in particular to a formwork support structure for concrete cast-in-place construction. Background technique [0002] The formwork support used for cast-in-place concrete walls in construction projects generally adopts the combination of steel pipes and metal fasteners to connect wooden squares. The existing problems are that the assembly and construction workload is large, time-consuming and laborious, serious wood loss, and low construction efficiency. high cost. And the poor flatness of the formed formwork support surface brings troubles to the laying of the formwork, and causes poor molding quality of the concrete wall. [0003] With various design requirements in the building construction process, the concrete formwork can be poured to meet the design requirements by increasing the height of the wall.

[0002] The formwork support used for cast-in-place concrete walls in construction projects generally adopts the combination of steel pipes and metal fasteners to connect wooden squares. The existing problems are that the assembly and construction workload is large, time-consuming and laborious, serious wood loss, and low construction efficiency. high cost

And the poor flatness of the formed formwork support surface brings troubles to the laying of the formwork, and at the same time leads to poor molding quality of the concrete wall

[0003] With various design requirements in the building construction process, the concrete formwork can be poured to meet the design requirements by increasing the height of the wall. The higher the building floor, the higher the height of the concrete pouring rise correspondingly, and the force that the formwork bears is in There are differences in the vertical direction. Therefore, the traditional method of supporting the formwork with only one support point can no longer meet the needs of high formwork. Therefore, a formwork support structure for concrete cast-in-place construction is urgently needed
