Description

Composite deck beam assembly{COMPLEX DECK-GIRDER ASSEMBLY}

The present invention relates to a deck beam assembly, and 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 in a direction perpendicular to the longitudinal direction of the beam. This relates to a composite deck beam assembly that can be easily assembled in the field as well as in factory assembly by forming a side wall unit and fastening it.

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.

Additionally, a method of forming a beam form by bending the deck plate at a right angle to the longitudinal direction of the protrusion has been proposed. The conventional deck plate beam formwork has the protrusions of the deck plate at right angles to the longitudinal direction of the beam, so it is easy to withstand the lateral pressure of the concrete when pouring the beam concrete, and only needs to be cut and bent as needed along the longitudinal direction of the deck plate, so it can be used in various ways. While there is an advantage that it is easy to adapt to the size of the beam, there is a disadvantage that a plurality of bent deck plates must be connected to the length of the beam.
