Description

Assembled deck plate beam form {ASSEMBLED GIRDER FORM USING DECKPLATE}

The present invention relates to a prefabricated deck plate beam form. More specifically, in manufacturing a beam form using a deck plate, the fastening protrusions of the deck plate are formed along the longitudinal direction of the beam to form a floor unit, and the fastening protrusions of the deck plate are formed along the longitudinal direction of the beam. It relates to a prefabricated deck plate beam form that forms side wall units along the height direction of the beam in a perpendicular direction and prevents the floor unit from opening when concrete is poured.

Generally, in ramen structures such as reinforced concrete structures or steel reinforced concrete structures, the load applied to the slab is transmitted to support members such as beams or girders. To construct such a reinforced concrete structure, pillars are installed, each pillar is connected with a beam, and then a slab is installed between the beams.

The form of a conventional beam or girder forms a support panel and a side panel made of plywood or Euroform, and reinforcing bars and stirrups are installed on the inside to be spaced apart.

This type of beam formwork had the problem of being uneconomical because it required a lot of manpower to install the form, and it also took a lot of manpower and cost to install a support structure to support the form.

In order to solve these problems of the conventional beam formwork, a method of using a deck plate as a beam formwork has been proposed.

As a beam form using a deck plate, a method has been proposed in the past to form a deck plate with T-shaped protrusions or L-shaped protrusions with the longitudinal direction of the protrusions in the longitudinal direction of the beam form. However, in the conventional deck plate beam form, since the longitudinal direction of the protrusion coincides with the longitudinal direction of the beam, there is a high risk that the protrusion and deck plate will be deformed or damaged by the lateral pressure of the concrete when pouring concrete into the beam form. U-shaped stirrups must be fixed by welding, etc., or separate reinforcing temporary members must be installed on the outside of the beam form. However, these temporary materials are difficult to install in advance at the factory and must be installed on site, so the problem is that labor on site increases. there is.

In particular, when using the inside of the beam as a work passage, there was a problem that it was difficult for workers to pass on site if the width of the beam with stirrups installed inside the beam form was narrow.

In addition, the conventional deck plate beam formwork inevitably changes the size of the beam depending on the structure, and there is a problem in that it is difficult to install stirrups and external reinforcing temporary members to match the sizes of various beams.

In addition, when loading deck beams manufactured in a U-shape by connecting the side plates and bottom plates at the factory, a large loading space is inevitable, and there was a problem in that construction of deck beams was difficult if sufficient loading space was not secured.
