Truss Girder Modular Wall Deck Plate {Integrated Deck Plate with Truss Girder}

The present invention relates to a deck plate used in a construction site, and more specifically, a truss girder module that can be easily constructed by manufacturing a deck plate in which a truss girder is modularized to meet various heights required according to wall specifications. It relates to a type wall deck plate.

The wall deck plate applied to building structures is manufactured by synthesizing structural steel truss girder and plate materials (steel plate, plywood, synthetic resin plate) to match the height of the wall to be constructed in the factory, then transporting it to the construction site and installing it on site. It is a construction method that reduces construction labor and shortens the construction period by minimizing the work of

However, in the case of a wall with a large height in the wall deck plate, since it is impossible to produce dividedly, there is a disadvantage that it cannot be installed by manpower due to the weight in a site where it is difficult to use the equipment, and when dismantling the foam after pouring concrete in a narrow space, there is a disadvantage. The disadvantage is that it is quite difficult to move by

In addition, the unit plate constituting the wall deck plate consists of long and short sides, and the short side is made in the construction length direction of the deck plate, and the long side is manufactured in the height dimension of the wall. In the case of the short side, it is manufactured with a certain length and can be assembled by connecting neighboring plates with wedge pins or bolts, but the long side corresponding to the height of the wall cannot be divided. There is a problem that the installation becomes inconvenient.

In relation to the conventional construction method due to this, Korean Patent Registration No. 0770698 describes a method of fixing a truss girder by mounting a deck plate to a deck plate, and Patent Registration No. 1136582 relates to a non-welded reinforced truss integrated deck plate. Although the technology has been disclosed, this method is inconvenient for the construction work itself, and it is difficult to apply to long spans because the buckling strength against the compressive force of the upper element cannot be increased. Therefore, there is a problem that the floor height increases.

In addition, the present invention produces a modular deck plate that can be varied according to the wall height at the factory, and after releasing the pre-fabricated module deck plate, the structural steel truss girder and the plate are synthesized to match the height of the wall at the construction site. An object of the present invention is to provide a truss girder modular wall deck plate that can secure variableness.

In addition, the present invention is a truss girder modular type in which the combination of deck plate and truss girder can be easily fastened anywhere without special equipment, thus minimizing assembly time, and ensuring plate distortion and structural safety at the synthesis point of the module deck plate. It aims to provide a wall deck plate.

The present invention for achieving these objects is a GMT plate formed integrally by arranging unit deck plates adjacent to each other according to design specifications and binding them together, and a wall deck plate by a truss girder installed in multiple stages in the longitudinal direction of the GMT plate. The truss girder includes an upper chord fixedly installed on the upper horizontal portion and a pair of lower chords fixedly installed on both sides of the lower tip portion, and consists of a lattice wire for binding them, and at the same time, a wall between the upper chord and the lower chord Reinforcing means is interposed to block the lateral pressure generated in It consists of a hook for hanging and fixing.

In addition, the support block has a concave groove on both sides of the bottom surface of the body into which the lower chord is fitted and a cut-out groove in which the reinforcing plate ( ) is fitted and fastened by a bolt, respectively, to adjust the gap with the reinforcing plate in the locking ring.
