Special-shaped beam formwork quick mounting and dismounting structure using electromagnetic force and mounting and dismounting method thereof

Abstract

The invention relates to the field of building construction, in particular to a special-shaped beam formwork quick mounting and dismounting structure utilizing electromagnetic force and a mounting and dismounting method thereof. The special-shaped beam formwork quick mounting and dismounting structure comprises a pair of fixing plates 1, a shaping block 2, an angle-variable fixing block 4 and a formwork 3, wherein the shaping block 2 and the angle-variable fixing block 4 are magnetically attracted between the pair of fixing plates 1 along the cross section shape of a special-shaped beam, and the formwork 3 is clamped between the shaping block 2 and the angle-variable fixing block 4. The fixing plates 1 comprise flat rectangular shells 1.1, horseshoe-shaped iron cores 1.2 arranged in the shells 1.1, coils 1.3 wound on the horseshoe-shaped iron cores 1.2, controllers 1.4 connected with the coils 1.3 and current stepless regulating switches 1.5 arranged on the controllers 1.4. After the shells 1.1 are electrified, a magnetizer plate 1.6 is formed, and rectangular grids are drawn on the magnetizer plate 1.6. The shaping block 2 comprises an internal shaping block 2.1, an external end part shaping block 2.2 and an external standard shaping block 2.3; and a magnetizer block is formed after the shaping block 2 passes through. The problem that material waste is caused due to the fact that when the special-shaped beam formwork is fixed, a large number of turnover materials need to be cut to erect a fixed scaffold is solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a fast installation and disassembly structure of a special-shaped beam template using electromagnetic force and an installation and removal method thereof. Background technique [0002] The special-shaped beam structure means that the shape of the cross-section of the beam is special-shaped, not the rectangle of the ordinary frame structure, such as rainbow beams, arc (curved) beams, etc. The on-site pouring process of the special-shaped beam structure is complicated, and the prefabrication cost is high, especially when the special-shaped beam structure inside the building is variable, the construction cost rises sharply. [0003] A magnet is a permanent magnet with a magnetic field around it, and the form of existence in its magnetic field space is a magnetic medium, and air, vacuum, or other substances are all magnetic media. In cement concrete, the hydrated tetracalcium a...
