Composite bearing deck comprising deck panel and concrete

Abstract

Disclosed is a composite bearing deck, including a deck panel, having an upper flange, a lower flange spaced from the upper flange by a predetermined height, a plurality of side webs formed between the upper flange and the lower flange in a transverse direction of the composite bearing deck, and a plurality of hollow portions defined by the upper flange, the lower flange and the side webs and arranged continuously in a longitudinal direction of the bearing deck while being long formed in the transverse direction thereof to constitute a tubular shape; and a concrete slab, having a predetermined thickness and integrated on the deck panel. Moreover, the composite bearing deck of the current invention can be further economically manufactured, and is advantageous in terms of prevention of brittle failure, and higher resistance to automotive loads and vibration loads, compared to conventional bearing decks.

What is claimed is:  
     
         1 . A composite bearing deck, comprising: 
 a deck panel, including    an upper flange,    a lower flange spaced from the upper flange by a predetermined height, and    a plurality of side webs formed between the upper flange and the lower flange in a transverse direction of the composite bearing deck, whereby a plurality of hollow portions are formed by the upper flange, the lower flange and the side webs, and arranged continuously in a longitudinal direction of the composite bearing deck while being long formed in the transverse direction thereof to constitute a tubular shape; and    a concrete slab, having a predetermined thickness and integrated with an upper part of the deck panel.    
     
     
         2 . The composite bearing deck as defined in  claim 1 , wherein the deck panel comprises a plurality of connected panel units each including the lower flange, the upper flange, the plurality of the side webs, and the plurality of the hollow portions, 
 in which the lower flanges of neighboring panel units to be connected are overlapped and integrated to form a joint of the panel units,    I-shaped beams elongated in a transverse direction of the composite bearing deck are integrated on the joint of the panel units, and    concrete is poured onto the deck panel so that the I-shaped beams are embedded in the concrete, to obtain the concrete slab in a reinforced state.    
     
     
         3 . The composite bearing deck as defined in  claim 1 , comprising a plurality of deck units each including a deck panel having a predetermined width and a precast concrete slab, combined together, 
 in which the lower flanges of the deck panels of neighboring deck units to be connected are overlapped and integrated to form a joint of the deck units,    I-shaped beams elongated in a transverse direction of the composite bearing deck are integrated on the joint of the deck units, and    a filling member is filled between the deck panels of both the deck units provided with the I-shaped beams so that the I-shaped beams are embedded in the filling member, to obtain a joint structure of the deck units in a reinforced state.
