Truss reinforcement stair

Abstract

The invention relates to a truss reinforcement stair, comprising a low-end cross beam, a high-end cross beam and a stair plate which extends from the low-end cross beam to the high-end cross beam, wherein the extension direction of the stair plate is longitudinal; the stair plate comprises a plurality of steps which are arrayed along the longitudinal direction; the length direction, vertical to the longitudinal direction, of the steps is horizontal. The truss reinforcement stair is characterized in that the stair plate comprises a longitudinal truss which is arranged longitudinally and a horizontal truss which is arranged horizontally. The truss reinforcement stair is capable of forming a bidirectional space stressed structure, and the stressed structure is more stable and reasonable; on one hand, the structure does not rely on concrete and has excellent rigidity and strength; one the other hand, the structure and the concrete can form an even elastomer which is different from the traditional reinforced concrete; therefore the stair has excellent rigidity and mechanical properties which are proved by tests, and becomes firmer; the thickness and the dead weight of the stair plate are greatly reduced by the structure, and the space and concrete materials are saved; the effects that the design and construction of the supporting structure of a stair support are easier and more convenient are achieved.

Description

Technical field [0001] The invention relates to a building decoration engineering structure, in particular to a staircase. Background technique [0002] Stairs are components used for vertical traffic between floors in buildings. It is usually composed of continuous steps of risers, platforms, and enclosure components. The current staircase usually adopts the conventional reinforcement method of arranging longitudinal steel bars and stirrups along the cross section of the stairs of the stairs. This method is widely used in engineering, the force is reasonable, and the construction is convenient. However, the risers are often thicker and increase the structural weight. , Making the design of the support structure of the stairs more difficult. And this shortcoming is particularly obvious in the spiral staircase. [0003] The truss is a plane or space structure with triangular elements composed of straight rods. Summary of the invention [0004] The invention overcomes the shortcom...

The current staircase usually adopts the conventional reinforcement method of arranging longitudinal steel bars and stirrups along the cross-section of the staircase. This method is widely used in engineering, with reasonable force and convenient construction. However, the staircase is often thicker, which increases the weight of the structure. , making it more difficult to design the support structure of the stairs

And this shortcoming is especially obvious in the spiral staircase
