Embodiment Construction

[0024] Such as Figure 1~4 As shown, the method for reducing the uneven deformation of the orthogonal steel bridge deck of the present invention comprises the following steps:

[0025] a. Install several main girder I-beams 2 along the length direction of the panel 1 under the panel 1, and fix the top flange of the main girder I-beam 2 on the bottom surface of the panel 1;

[0026] b. Install several first I-beams 3 side by side between two adjacent main girder I-beams 2, so that the web of the first I-beam 3 is perpendicular to the web of the main girder I-beam 2, And the first I-beam 3 is located in the middle of the web height direction of the main girder I-beam 2;

[0027] c. Install several groups of mutually orthogonal fourth I-beams 6 and fifth I-beams 7 between two adjacent main girder I-beams 2 on the bottom surface of the panel 1, and place the fourth I-beam 6 The top flange and the top flange of the fifth I-beam 7 are fixed on the bottom surface of the panel 1, an...

Abstract

The invention relates to a method for reducing uneven deformation of an orthogonal steel bridge deck slab and the deck slab. Girder I-shaped steel is arranged on the bottom surface of the deck slab, the length direction of the girder I-shaped steel is consistent with the length direction of the deck slab, and a top wing plate of the girder I-shaped steel is in contact with the deck slab to reduceoverall deformation of the deck slab. Fourth I-shaped steel and fifth I-shaped steel which are orthogonal are arranged on the bottom surface of the deck slab. The deformation of the deck slab betweenthe two pieces of girder I-shaped steel is borne by the fourth I-shaped steel and the fifth I-shaped steel which are orthogonal, and the force borne by the fourth I-shaped steel and the fifth I-shapedsteel is transmitted through third I-shaped steel to first I-shaped steel and second I-shaped steel which are orthogonal. Because the first I-shaped steel is fixed on a web plate of the girder I-shaped steel, the force is finally borne by the girder I-shaped steel. The girder I-shaped steel bears the pressure received by the deck slab through the girder I-shaped steel arranged side by side and the I-shaped steel orthogonally arranged between the girder I-shaped steel, uneven deformation of the deck slab is prevented, and therefore the deck slab or a truss structure is prevented from being damaged.

Description

technical field [0001] The invention relates to a steel bridge deck, in particular to a method for reducing the uneven deformation of an orthogonal steel bridge deck and the deck. Background technique [0002] With the rapid development of the bridge industry, the scope of application of steel bridges is increasing. Most of the bridge decks of steel truss bridges are steel bridge decks. The top of the deck is asphalt pavement or concrete pavement. To better bear the load, this kind of horizontal and vertical supporting steel deck structure is called "orthogonal steel deck". Uniform deformation. The current design of the steel bridge is to connect four longitudinal large I-beam girders with relatively thin small I-beam beams. The large I-beams directly contact the lower part of the bridge deck, and the small I-beams are connected to the large The middle of the steel waist does not directly touch the lower part of the bridge deck. The small I-beam plays a certain role in l...
