Description

Truss-integrated deck plate with anti-opening function {Truss-integrated deck plate with anti-opening function}

The present invention relates to a truss-integrated deck plate having an anti-expansion function, and more specifically, in the process of pouring concrete into the deck plate, it is possible to prevent the deck plate from being deformed due to the spread of the concrete pouring load, thereby preventing the deck plate from being deformed. It relates to a truss integrated deck plate having an improved anti-expansion function capable of ensuring dimensional stability.

In general, a deck plate is formed as a slab formwork in reinforced concrete construction, and a truss is placed on the downward bend of the deck plate, and the shape and dimension are maintained during concrete pouring and condensation reinforcement, thereby reducing the amount of moisture required for its hardening. As a mold for forming a concrete member that prevents leakage and is not affected by the outside air, the conventional deck plate places a truss on the downward curved part, buries it with concrete, and in the process of reinforcing condensation, the weight of the concrete and the Unable to withstand the load, impact and lateral pressure of the concrete, deformation occurs on both sides of the deck plate, causing the truss installed on the deck to be separated from the deck or the size of the deck plate to be deformed, which causes a huge obstacle to the installation of the deck plate There is a problem.

In an effort to solve the above problems, the utility model registration No. 20-0231044 (Registration date: May 8, 2001) The device for preventing sagging of deck panels of reinforced concrete slabs can sufficiently withstand the weight of concrete and the construction load. In the deck panel composed of a deck plate of a predetermined thickness and a truss girder fixedly installed on the upper surface of the deck plate in the longitudinal direction, the upper part of the truss girder is spaced apart from the truss girder at a predetermined interval. It is characterized by being connected to reinforcing bars to sufficiently support the load of the slab.

However, the deck panel with the above configuration has a structural feature of preventing the deck panel from sagging to the lower side due to the load of the concrete poured inside the deck panel, but in the case of a gold deck, a ship protruding on both sides of the corrugated part The transformation of the calling phenomenon has a constitutive limit that cannot be prevented.

As another prior art, Utility Model Registration No. 20-0242901 (registration date: August 2, 2001) reinforcing bar spacer for deck plate, in forming a reinforcing bar spacer for concrete desk plate, the connection part of the center of the steel bar and the connection part An inclined portion is formed on the outside of the inclined portion, two spacers are formed parallel to the upper end of the inclined portion, a plurality of reinforcing bar mounting portions 104 are formed on each spacer, and the ends of the spacers are bent downward to inwardly bend. By forming a portion, it is characterized in that it is formed by fitting and fastening with the elasticity of the spacer at regular intervals to the downward curved portion of the deck plate, and seating the reinforcing bar in the reinforcing bar mounting portion of the spacer.

However, the reinforcing bar spacer for deck plate having the above configuration is installed in the downward curved portion of the deck plate in a state where the reinforcing bars are bent in various directions, and then concrete is poured to prevent deformation of the deck plate according to the weight of the concrete. However, since the reinforcing bars are installed in the downward curved portion of the deck plate, it is difficult to properly respond to the load of the concrete, and there is a problem in that the dimensional deformation continues due to the continuing phenomenon of fullness of the deck plate due to the lateral pressure.
