Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] A multi-layer steel plate concrete composite beam of the present invention comprises an upper concrete layer 1 and a lower concrete layer 2, an upper steel plate 3 is arranged on the top of the upper concrete layer 1, and a middle steel plate is arranged between the upper concrete layer 1 and the lower concrete layer 2 4. The bottom of the lower concrete layer 2 is provided with a lower steel plate 5, the upper steel plate 3 and the middle steel plate 4 are fixed by the upper bolt 6, the middle steel plate 4 and the lower steel plate 5 are fixed by the lower bolt 7, the upper steel plate 3 and the middle steel plate An upper stirrup 8 is arranged between the 4, and a lower stirrup 9 is arranged between the middle steel plate 4 and the lower steel plate 5. Such a composite design of concrete and steel plates, through three-layer steel plates and upper and lower...

Abstract

The invention provides a multi-layer steel plate and concrete composite beam which comprises an upper concrete layer and a lower concrete layer. An upper steel plate is arranged on the top of the upper concrete layer. A middle steel plate is arranged between the upper concrete layer and the lower concrete layer. A lower steel plate is arranged at the bottom of the lower concrete layer. The upper steel plate and the middle steel plate are fixed through upper bolts. The middle steel plate and the lower steel plate are fixed through lower bolts. Upper stirrups are arranged between the upper steelplate and the middle steel plate. Lower stirrups are arranged between the middle steel plate and the lower steel plate. By means of the steel plate and concrete combination design, through the staggered bolts and stirrups, the multi-layer steel plate and concrete composite beam has the shear resistance, is high in shear resistance and simple in structure, and saves cost and raw materials.

Description

technical field [0001] The invention belongs to composite beams, in particular to a multilayer steel plate concrete composite beam. Background technique [0002] The beam formed by combining two different materials or different processes is called a composite beam, also known as a combined beam. Some main girders use one material, while the bridge decks connecting the main girders use another material; there are also composite girders composed of prefabricated reinforced concrete girders or prestressed concrete girders and reinforced concrete decks cast in situ. Composite beam is a transverse load-bearing member in which steel beam and concrete slab are connected as a whole through shear connectors. It can give full play to the advantages of steel tensile strength and concrete compression resistance. It has the advantages of good dynamic performance, small cross-sectional size of components, and convenient construction. Most of the current composite beams are composed of c...
