Problems solved by technology

[0003] The disadvantage of this type of concrete square stiff column formwork reinforcement system is that the operation is relatively cumbersome, and the workload of assembling, strengthening and dismantling the formwork system is relatively large, requiring a lot of labor and taking a long time; The pulling screw cannot be used in turnaround, and a lot of materials are wasted; the steel keel is too heavy, and it is extremely inconvenient to carry it manually; the number of structural parts is large, and the material loss is large; the steel formwork has poor applicability and cannot adapt to the diameter reduction of the concrete square rigid column section

Embodiment Construction

[0023] like Figure 1 to Figure 3 As shown, a square rigid column assembly type adjustable section formwork system, a rectangular structure composed of four face formwork 1, each two face formwork 1 is connected by an angle steel positioning piece 2, and the vertical angle steel positioning piece 2 is connected. There are several evenly distributed rectangular grooves in the direction, and a number of limit beams 3 are arranged on the outer surface of the surface formwork 1. The limit beam 3 is connected vertically; the surface formwork 1 is composed of several standard unit formwork and a non-standard unit formwork connected to each other. The standard formwork and the non-standard formwork are composed of angle steel, corner code and formwork, and the periphery is sealed with a hole frame. It is convenient for the two unit templates to be connected to each other; the limit beam 3 is composed of the outer square steel 31 and the inner square steel 32 plugged together. The le...

Abstract

The invention relates to a fabricated section-adjustable formwork system for square stiff pillars. The fabricated section-adjustable formwork system is of a rectangular structure formed by four surface formworks. Every two surface formworks are connected with each other through angle-steel positioning members. A plurality of evenly distributed rectangular grooves are formed in each angle-steel positioning member vertically. A plurality of limiting cross beams are arranged on the outer surfaces of the surface formworks. Two ends of each limiting cross beam are located in the corresponding rectangular grooves, and are vertically connected with the corresponding limiting cross beams on the adjacent surface formwork. Each surface formwork is formed by connection of a plurality of standard unit formworks and a non-standard unit formwork. Each limiting cross beam is formed by inserted connection of outer square steel and inner square steel, and the length of each limiting cross beam is adjusted according to the width of the corresponding surface formwork. The formwork system has the advantages that during turnover, damage degree is low, construction speed is high, auxiliary measures are few, and requirements on operation levels of operators are low; the formwork system is applicable to construction requirements of section changes of the square stiff pillars, is environment friendly and has high economic and social benefits.

Description

technical field [0001] The invention relates to a square rigid column assembly type adjustable section formwork system and a construction method thereof, which belong to the field of construction. Background technique [0002] As we all know, the current formwork reinforcement system for concrete square stiffness columns mainly adopts panel (wood, plywood, plastic board, etc.) + profiled steel or secondary corrugated wood + profiled steel main corrugation + connecting pieces (tension bolts, mountain-shaped clamps, nuts, etc.) , steel formwork + section steel keel + connector, steel-wood composite formwork + section steel keel + connector and other reinforcement methods, usually such methods are manually assembled into a formwork reinforcement system for concrete square stiffness columns. [0003] The disadvantage of this kind of concrete square stiffness column formwork reinforcement system is that the operation is more complicated, the assembly, reinforcement and dismantlin...
