Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] see Figure 1-Figure 5 , the present invention provides a technical scheme of a truss-type steel structure staircase: its structure includes an I-steel main beam 1, which is characterized in that: the I-steel main beams 1 are all vertically fixed on the floor in turn; and the I-steel main beam The number of beams 1 is four; and they are arranged in a square shape. The front and rear ends of the top of the I-steel main beam 1 are horizontally aligned and welded with an I-steel beam 2, and the left and right ends of the top surface of the I-steel main beam 1 are aligned horizontally. The I-steel longitudinal beam 3 is welded, and the I-steel beam 2 and the I-steel longitudinal beam 3 form a rectangular structure; and a platform 6 is installed...

Abstract

The invention relates to a truss type steel structure stair which structurally comprises I-shaped steel main beams and is characterized in that the I-shaped steel main beams are sequentially and vertically fixed on a floor; the number of the I-shaped steel main beams is four; i-shaped steel cross beams are welded to the front end and the rear end of the top face of the I-shaped steel main beam in a horizontal alignment mode, I-shaped steel longitudinal beams are welded to the left end and the right end of the top face of the I-shaped steel main beam in a horizontal alignment mode, and the I-shaped steel cross beams and the I-shaped steel longitudinal beams form a rectangular structure. A platform is installed on the rectangular top face, cross rods are welded to the I-shaped steel main beams at equal intervals of the height, inclined rods are welded to the cross rods in a diagonal mode, and first connecting plates are welded to the tail portions of the right sides of the I-shaped steel cross beams in a horizontally-aligned mode, and the truss type steel structure stair is convenient to install, high in construction efficiency and diversified in structure.

Description

technical field [0001] The invention relates to a truss type steel structure staircase, which belongs to the field of truss type steel structure stairs. Background technique [0002] Stairs are an important part of housing construction. For different buildings, there are only two types of stairs that can be selected: beam stairs and slab stairs. During the industrialization of residential steel structures, the problem of stairs has become more and more prominent. , Concrete structure stairs, complex construction process, low technical and economic benefits, but existing stairs have two types of beam stairs and slab stairs, and the form is too monotonous. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a truss-type steel structure staircase to solve the existing problems. [0004] In order to achieve the above object, the present invention is achieved through the following technical solution...
