Description

A slope-type beam formed with a deck support that ensures safety by preventing the deck from falling off {Assembly type beam mold with a upper plate}

The present invention relates to a slope-type formwork beam comprised of a deck support that ensures safety by preventing the deck from falling off. More specifically, the cross-section is constructed using a pair of lower steel plates and a pair of unit members to determine the width of the beam. Not only can the cross-section be configured in various ways by adding unit members according to the dance, but a separate deck support for mounting a deck, etc. at the upper end of the unit member at the top of the cross-section is provided to provide a sufficient mounting surface for a steel deck, etc. This relates to a slope-type formwork beam composed of a deck support that ensures safety by preventing the deck from falling off while securing the rigidity of the mounting surface.

A formwork is a structure temporarily installed to shape fluid concrete into a predetermined shape and size in reinforced concrete structures or steel reinforced concrete structure construction. Formwork is a temporary material that is needed for a short period of time until the concrete has cured to a certain extent and is removed after the concrete has cured. The installation and dismantling of the formwork takes up a very large portion of the cost and time required for the entire concrete construction. It is a cumbersome process. In particular, since a form material with high rigidity and low price is used, the self-weight of the form is considerable, and the work of assembling and dismantling heavy materials at a high place is sometimes accompanied by risk.

Conventionally, various materials such as plywood and steel plates are used as formwork materials, and they usually consist of a block panel in contact with unhardened concrete and braces, strips, and long-term lumber that support it. In particular, the steel form was relatively heavy and had to be assembled and dismantled using mobile equipment such as a crane, the initial investment cost was high, and the use of angles, etc. as wales was a significant burden due to the size and self-weight.

In order to solve these problems of the conventional formwork, a slope-type formwork beam technology that remains without dismantling even after the concrete hardens has been proposed.

In the case of a slope-type formwork beam, a deck or PC slab, etc. is mounted on the upper part. At this time, the mounted part is mounted on the upper part of the side member that forms the cross-section, so there is a risk of the deck or PC slab, etc. falling off due to the small mounting area and lack of rigidity. There was this.

In the above background technology, 'a lower plate formed in a rectangular shape with a length corresponding to the length of the beam structure to be constructed; It has a length corresponding to the length of the lower plate, the lower end is fixed to one side of the lower plate, and one or more first beads formed along the longitudinal direction on the inside are connected to each other along the width direction. First side plates arranged to be spaced apart; It has a length corresponding to the length of the lower plate, the lower end is fixed to the other side of the lower plate, is erected on the other side of the lower plate, and is formed inward along the longitudinal direction and corresponds to the position of the first bead facing one or a second side plate on which a plurality of second beads are arranged to be spaced apart from each other along the width direction; And one or a plurality of side plate support members arranged horizontally and spaced apart from each other along the longitudinal direction of the first bead and the second bead, and both ends of which are coupled to each of the first bead and the second bead corresponding to the horizontal direction. The first bead and the second bead are extended in the inner horizontal direction and then their ends are bent upward to form a first seating groove, and the side plate support member has both ends corresponding to the first seating groove. We propose a beam structural form that is bent downward into a shape and then extended in the horizontal direction and inserted into the first seating groove.

However, in the above background technology, each member is manufactured using a roll forming method, and the cross-sectional configuration is very complicated, so not only is forming very difficult, but the manufacturing cost increases, and the type and number of constituent members required to respond to beams of various sizes increases. There is a problem with doing so.
