Description

Wall body of elevator shaft

Technical Field

The utility model relates to the technical field of elevators, in particular to a wall body of an elevator shaft.

Background

The elevator shaft is an important component of multi-layer and high-rise buildings, and the elevator shaft is mostly filled with concrete in a template to ensure the strength, so the strength of the elevator shaft mainly depends on the design thickness of the concrete. When the thickness of the concrete in the elevator shaft is too high or too thick, the stress of the elevator shaft shear wall is uneven or unreasonable, so that the strength of the elevator shaft shear wall cannot be ensured, and potential safety hazards such as elevator shaft collapse and the like exist.

The Chinese patent with the publication number of CN206337673U discloses an elevator shaft shear wall, which comprises an outer shell and an inner shell inside the outer shell, wherein the cross sections of the outer shell and the inner shell are rectangular, the outer shell is formed by connecting four steel plates, the inner shell is also formed by connecting four steel plates, the connecting parts of the adjacent steel plates form corner parts, longitudinal steel bars for increasing the strength and transverse steel bars for preventing deformation are distributed between the outer shell and the inner shell, concrete is filled between the outer shell and the inner shell, and the steel plates are connected in a welded mode. The elevator shaft shear wall is more reasonable in stress, difficult to deform, convenient to construct, safe and reliable, and the concrete and steel consumption is saved compared with the conventional design, the engineering quality is more ensured, and the construction cost is obviously reduced. But the strength of the elevator shaft shear wall mainly depends on the thickness of concrete and longitudinal steel bars, but because the longitudinal steel bars are vertically arranged, the stress concentration of the elevator shaft shear wall is easy to cause the breakage of the longitudinal steel bars, the strength of the elevator shaft shear wall still cannot be ensured, so that the elevator shaft shear wall still has potential safety hazards such as elevator shaft collapse and the like, and the steel plate is easy to stagger or separate from the concrete due to different deformation coefficients of the steel plate and the concrete, thereby losing the advantage of the joint work of the steel plate and the concrete. Thus, we propose a new wall for an elevator hoistway.
