Big template combined by small steel templates

Abstract

The invention discloses a big template combined by small steel templates, which comprises the small steel templates, connectors and a reinforcing device, and is characterized in that: the combined bigtemplate is formed by connecting and fixing the plurality of small steel templates by the connectors according to the required size and then reinforcing the combined template by the reinforcing device. The small steel templates are combined and spliced into the big template with any size according with modulus, and the big template is taken as a concrete wall template which is reinforced throughconnecting, fixing and rigidity strengthening devices to form the big template capable of being integrally assembled and disassembled. The big template fully uses the resources of the prior small steel templates and the characteristic of flexible assembly of the small steel templates, can be repeatedly used and locally repaired and replaced, has multiple functions, and is integrally assembled andsupported, thereby having the advantages of reducing the engineering cost along with convenience and quickness.

Description

Technical field: [0001] The invention belongs to a combined large formwork used in construction engineering. Background technique: [0002] At present, during the construction of cast-in-place reinforced concrete external walls, the large formwork used mainly includes the following types. The large formwork is all wooden, and the amount of wood used is relatively large, and the cost is relatively high. The steel-wood mixed formwork has poor integrity and cannot withstand bumps and impacts with large impacts. The board surface is soft and easy to break. The all-steel large formwork has a large self-weight and steel consumption, a large initial investment, and a small number of turnovers. It cannot be used for multiple purposes, and the project cost is high. In non-standard floors, small steel forms are generally used as formwork, and the construction of small steel forms is slow. It is cumbersome. After the formwork is removed and landed, it is transported to the next constr...

The steel-wood mixed formwork has poor integrity and cannot withstand bumps and impacts with large impacts. The board surface is soft and easy to break

The all-steel large formwork has a large self-weight and steel consumption, a large initial investment, and a small number of turnovers. It cannot be used for multiple purposes, and the project cost is high. In non-standard floors, small steel forms are generally used as formwork, and the construction of small steel forms is slow. It is cumbersome, after removing the formwork to the ground, it is transported to the next construction section, and the formwork is reassembled. The labor cost is high, the time is long, and the formwork is easily damaged.
