Description

Self-supporting beam form support device {SUPPORTING DEVICE FOR BEAM FORM}

This design is a device that maintains the side and bottom of the beam form at a right angle and can be applied to changes in the width and height of the beam. Here, the side support directly transfers the concrete pouring load of the slab transmitted to the side form of the beam to the lower yoke. It relates to a device that can support a vertical load so that it can reach the beam through the material. More specifically, it can adjust the length and width of beam formwork with various sizes of width and height and adjust the rigidity or size of the support part. This relates to a self-supporting beam form support device that can secure sufficient support even if it is small.

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., and 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, which is a problem that increases labor on site. There is.

In particular, when using the inside of the beam as a work passage, there is a problem that it is difficult for workers to pass on site if the width of the beam with stirrups installed inside the beam form is 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 in that it is easy to adapt to the size of the beam, a process of partially cutting and then bending the formed steel plate through the deck plate production facility is added considering the height and width of the beam, and a plurality of bent deck plates are added. It has the disadvantage of having to be connected according to the length of the beam.

Meanwhile, in the conventional beam form, a support device for supporting the beam form is installed on the outside of the beam form in addition to the form bar. However, in the conventional beam form support device, the size of the form changes depending on the size of the beam, so there are various There was a problem that it took a lot of time and manpower to install a form support device corresponding to the size of the beam.
