Fishbone-shaped corner armor for building stair

Abstract

The invention discloses a fishbone-shaped corner armor for a building stair. The fishbone-shaped corner armor comprises a stair base layer, a slurry layer plastered on the stair base layer and a corner armor body buried in the slurry layer. The corner armor body comprises main rods and auxiliary rods. The main rods are arranged on the external corners of the stair base layer and comprise the first main rods and the second main rods, the first main rods and the second main rods are fixedly connected, and the auxiliary rods are fixedly connected to the first main rods and the second main rods. Each auxiliary rod comprises a first auxiliary rod body and a plurality of second auxiliary rod bodies fixedly connected to the first auxiliary rod body, and the second auxiliary rod bodies are distributed in a fishbone shape. The fishbone-shaped corner armor for the building stair is simple and firm in structure and convenient to manufacture, the external corners of the stair are effectively protected, raw materials are greatly saved, plastering is easy, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a bone-shaped corner protector for a building staircase. Background technique [0002] The stairs of a building are the only way for people to pass. If the corners of the stairs are complete, it will not only be beautiful, but also ensure the safety of pedestrians. However, in the existing stairs, some of the corners of the steps before handing over have been damaged, which affects the quality of appearance; [0003] When the reinforced concrete stair steps adopt the cement mortar surface layer, the external corners of the stair steps are easy to be damaged due to bumps during the process of carrying large and heavy objects by the user, and the damaged external corners of the stair steps are not easy to repair, which affects the normal use of the stairs . In order to solve the above-mentioned problem that the outside corner of the stair step is easily damaged a...

Problems solved by technology

However, some of the existing stairs have been damaged at the corners of the steps before they are handed over, which affects the quality of appearance;

[0003] When the reinforced concrete stair steps adopt the cement mortar surface layer, the external corners of the stair steps are easy to be damaged due to bumps during the process of carrying large and heavy objects by the user, and the damaged external corners of the stair steps are not easy to repair, which affects the normal use of the stairs

In order to solve the problem that the outside corner of the stair step is easily damaged and not easy to repair after being damaged, it is necessary to install a corner guard at the outside corner of the stair step during the actual plastering construction of the stair step

However, there is no uniform, standardized and specific construction method to follow when plastering cement mortar stairs, so there are inevitably random, irregular construction operations and positive corners of stairs in the plastering layer during actual construction. There are many problems such as unreasonable structure and layout position, poor construction quality of cement mortar stair step outside angle, etc.

Most of the male angle structures currently used usually use a single main rod, and then a secondary rod is welded on the single main rod. This kind of external angle structure is poor in stability and can be used for a long time. Not conducive to protecting the sun angle of the stairs
