Description

Prefabricated steel frame assembly with permanent form panel

According to the present invention, the permanent formwork panel can be firmly supported on the steel frame assembly in a simple manner without a separate fastening member, thereby improving workability, economic efficiency, and shortening the air, and the corner beads can be easily constructed at the corner where the permanent formwork panel meets. It is about a prefabricated steel frame assembly with a permanent formwork panel that can effectively resist the concrete side pressure concentrated at the edge of the member.

The formwork is installed for a short period of time until the concrete paste is cured in order to make the concrete into a predetermined shape and dimensions. Existing formwork is supported by a support frame for preventing deformation, which is heavy in weight and supported by external construction. Material and construction amount is considerable.

The rigid cast steel is placed outside the member and the formwork is directly coupled to the lateral support member in the steel concrete composite member (PSRC) using a pre-assembled steel frame assembly having a lateral support member that connects them in the lateral direction from the outside. Technology has been developed and used (Patent No. 10-1490748, etc.).

The technology has the advantage of eliminating the temporary material for supporting the formwork to reduce the cost and shorten the air as well as to improve the safety of the operator.

In the past, such formwork was used to form the formwork of the steel sheet to be demoldable or for permanent presence.

However, on the site where the steel sheet may be corroded or need to take extra measures against fire, mortar panel or FRP panel is used as permanent formwork.

However, since these types of panels are thicker and have a larger weight than the steel sheets, it is difficult to fix them to the lateral support members of the pre-assembled steel frame assembly by a direct screw or the like. In addition, since the fastening member is exposed to the outside, there is a risk that the permanent formwork panel may fall off due to damage of the fastening member in case of fire.

On the other hand, there is a disadvantage that the side pressure is concentrated in the corner of the member when the neighboring permanent formwork panel meets during concrete pouring.

This may be considered to close the corner bead by installing the corner bead, but first, it was difficult to construct the corner bead between the two permanent formwork panel sliding sideways.
