Description

Composite Beam-Deck Using Deck Plate and Method of Manufacturing the Same}

The present invention relates to a composite beam-deck and a method of manufacturing the same. More specifically, a plurality of deck plates of three types of standards are assembled and combined to form a deck module, and then a plurality of deck modules are placed on the pillars of a building. By installing and connecting them, it is possible to apply it to beams of various specifications and maximize production efficiency, and at the same time, it is easy to demold the beam after construction, and the demolded beam-deck can be recycled. Composite beam-deck and its manufacture It's about method.

In general, a concrete structure is a composite structure in which concrete, which is a compressive material, and rebar, which is a tensile material, are used together. A form is installed with plywood, square lumber, etc., and rebar is placed in the form, and then the concrete is poured, cured, and the form is performed. It is constructed through repetition of the dismantling process.

This formwork is a temporary structure installed temporarily to shape fluid concrete into a predetermined shape and size until the concrete is cured. Formwork is essential in a reinforced concrete structure.

In general, the form consists of a form panel to form the concrete surface and a frame bar to support the form panel. After the form is installed, temporary construction such as joists, yokes, and braces is required to support the form. do.

However, such temporary construction not only requires an excessive amount of temporary materials, but also requires a lot of time and money to assemble and dismantle the form or scaffolding, and requires a separate surface treatment process after demolding the form, making the process to be performed complex and inefficient. .

To solve this problem, in the prior art, Republic of Korea Patent No. 10-1009753, a U-shaped pre-assembled form made by bending a thin metal plate was developed.

In the prior art, the form is automatically produced by roll forming a thin steel plate with a thickness of 10 to 12 mm, so production is easy, and there is no separate support frame, so the weight is light and easy to handle and install.

In addition, since the form is brought to the site and installed as a finished product pre-assembled at the factory, field work can be minimized, reducing manpower input and shortening the construction period, and the construction period is shortened as the form demolding process is omitted as it is a non-dismantled permanent form. It is possible to prevent noise complaints and improve the on-site environment when removing formwork.

However, since the shape of the beam is different at each site and various types of beams are designed even at the same site, when applying this technology, roll forming must be manufactured separately for each beam specification, and a separate roll forming line is required according to the beam specification. ), so there is a problem that the initial cost is high.

In addition, since the required quantity for each standard must be manufactured separately, there are difficulties in material supply and inventory management.

In addition, stirrups placed inside the form are fixed by welding to support the lateral pressure when placing concrete. At this time, a simple spot weld is made to the ribs that are integrally bent in the form to protect against external force. There is a problem that the welded part falls off easily.

A deformed beam-deck each including a deck module including a side deck with stacked deck plates, a lower bar supporting the lower deck, and a support frame including side columns spaced apart in the longitudinal direction of the lower bar to support the side decks, respectively. , and a connecting structure for connecting adjacent demolded beam decks with the pillar structure in between, making it easy to demold the beam after construction, and recycle the demolded beam deck. Accordingly, a composite beam deck and a method of manufacturing the same can be provided that are easy to demold after the beam is constructed and can recycle the demolded beam deck.

In addition, the composite beam-deck according to an embodiment of the present invention includes a lower deck in which adjacent ends of a plurality of lower deck plates are joined so that they overlap horizontally, and a plurality of side parts perpendicular to each of both ends in the width direction of the lower deck. A deformed beam-deck each including a deck module including a side deck with stacked deck plates, a lower bar supporting the lower deck, and a support frame including side columns spaced apart in the longitudinal direction of the lower bar to support the side decks, respectively. By including it, it is possible to prevent the deformation of the beam form in the depth direction and the entire side plate from spreading due to the lateral pressure generated during the concrete pouring process. Accordingly, a composite beam-deck capable of performing stable beam construction and a method of manufacturing the same can be provided.

Above, embodiments of the present invention have been described with reference to the attached drawings, but those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. You will understand that it exists. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
