Embodiment 1

[0032] like Figure 1 ~ Figure 3 A rice-shaped steel structure staggered truss system is shown, including steel structure frame column 1, steel structure frame beam 2, steel structure truss 3 and steel truss laminated floor 4, steel structure frame column 1 is set in the steel structure staggered truss system All around, the column distance is 1 / 2 of the span distance between the steel structure trusses 3 on each floor, the steel structure frame beams 2 are riveted and welded to the rigid structure frame columns 1, and the steel structure trusses 3 are staggered in the steel structure staggered truss system , the steel structure truss 3 is connected with the rigid structure frame column 1 by riveting and welding, the steel structure truss laminated floor 4 is fixedly connected with the steel structure frame beam 2 and the steel structure truss 3, the basic unit of the steel structure truss 3 adopts a rice-shaped node truss structure, The steel structure truss 3 includes an upp...

Embodiment 2

[0035] A construction method of the staggered truss system of a rice-shaped steel structure, comprising the following implementation steps:

[0036] Step 1, according to the building and load conditions, determine the structural axis and arrange the steel structure frame columns 1, so as to determine the building span, and obtain the combined number of steel structure trusses 3;

[0037] Step 2, making the steel structure truss 3 in the factory, and fixedly connecting the rice-shaped web 7 inside the steel structure truss 3;

[0038]Step 3, riveting the steel structure frame beam 2 on the steel structure frame column 1 through bolts, and welding with the steel structure frame column 1 after the steel structure frame beam 2 is fixed;

[0039] Step 4, hoisting the steel structure truss 3 layer by layer and riveting it on the steel structure frame column 1 through bolts, and welding with the steel structure frame column 1 after the steel structure truss 3 is fixed;

[0040] Step...

Abstract

The invention provides a meter-shaped steel structure staggered truss system and a construction method thereof. The meter-shaped steel structure staggered truss system includes steel structure frame columns, steel structure frame beams, steel structure trusses and steel bar truss composite floor slabs, the steel frame columns are arranged around the steel structure staggered truss system, and thecolumn distance of the steel frame columns is 1 / 2 of the span distance between the steel structure trusses on each floor; the steel structure frame beams are connected to the steel structure frame columns in rivet welded and mixed modes, the steel structure trusses are arranged in the steel structure staggered truss system in a staggered mode, and the steel structure trusses and the steel structure frame columns are connected in rivet welded and mixed modes; and the steel bar truss composite floor slabs are fixedly connected with the steel structure frame beams and the steel structure trusses,and foundation units of the steel structure trusses adopt the meter-shaped joint truss structure. According to the meter-shaped steel structure staggered truss system and the construction method thereof, the structure is reasonable, construction is convenient, and the problem that open web trusses and diagonal web member trusses are mostly used in the staggered truss system, and consequently anti-seismic properties of the open web trusses and the diagonal web member trusses are limited is solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a staggered truss system of a rice-shaped steel structure and a construction method. Background technique [0002] The steel structure staggered truss system is obviously superior to ordinary steel structures in structure. It is a structural system with high efficiency, economy and practicality, and flexible space layout. It is widely used in various high-rise residential buildings, office buildings, large banquet halls and other buildings. The steel structure staggered truss system consists of trusses, beams, columns and slabs. The height of the trusses is the same as the floor height, and the span is the same as the width of the building. The steel structure trusses are staggered within the unit span. Although the trusses are arranged in a staggered manner, the space provided by each floor slab can make it bear similar forces to the frame-shear structure under ...
