Support device for early removal template

Abstract

The invention discloses a support device for an early removal template. The device comprises a supporting column, and further comprises a stable lifting mechanism, a reinforcing supporting mechanism and a top supporting mechanism; the stable lifting mechanism disposed inside the supporting column comprises oriented sliding bars and a lifting screw rod, the oriented sliding bars are located on twosides of the lifting screw rod, a lifting horizontal plate is connected between the oriented sliding rod and the lifting screw rod, the bottom of the lifting screw rod is provided with a driven gear,the bottom of one side of the supporting column is rotatably provided with an adjusted handle, and one end of the adjusting handle is provided with a driving gear which drives the driven gear to rotate; the reinforcing supporting mechanism comprises a stable supporting rod on the top of the supporting column and an early removal bracket which sleeves a stable supporting rod, one end of the stablesupporting rod is welded with the lifting horizontal plate, the stable supporting rod is lifted and lowered during the movement of the lifting horizontal plate, and the bottom of the early removal bracket is also butted with a reinforcing seat. The device has strong stability, and can adapt to floor slabs after the early removal at different heights, and the use effect of the support device is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a support device for an early demolition formwork. Background technique [0002] The early demolition formwork technology can be applied to the construction of floor slabs and beams of various types of public buildings, residential buildings, floor slabs and beams of frame structure buildings, and structural roof formwork of bridges, culverts and other municipal projects. Early demolition of the formwork is a formwork support device and method adopted for early demolition of the floor formwork. Its working principle is "remove the slab without dismantling the column". The stress state of the slab formwork is to keep the span of the slab formwork not exceeding the span requirements specified in the relevant codes. In this way, the floor slab formwork and some supports can be removed as long as the concrete strength reaches 50% of the design strength, while the inter-column, c...

Problems solved by technology

However, its adjustment method is mainly to connect multiple positioning holes arranged along the height direction through positioning pins. The arrangement of the positioning holes should not be too dense, otherwise it will affect the support strength of the adjusting column, and the sparsely distributed positioning holes will affect the adjustment column. The height adjustment accuracy is limited, the adjustment range is limited, and it cannot adapt to the height of the floor after the early demolition, and there are certain limitations in actual use.
