Steel bar layer at external corner part

Abstract

The invention relates to the technical field of constructional engineering, and discloses a steel bar layer at an external corner part. The position of the external corner part is provided with a first wall and a second wall which are perpendicular to each other. The steel bar layer at the external corner part comprises a plurality of truss ribs, a plurality of first upper iron stress ribs, a plurality of second upper iron stress ribs, a plurality of third upper iron stress ribs, a plurality of first upper iron distribution ribs, a plurality of radiation distribution ribs and a plurality of radiation stress ribs. The multiple radiation distribution ribs are evenly arranged in a radiation arc manner from the external corner part. The middle portions of the radiation distribution ribs are inan arc shape. One ends of the radiation distribution ribs are parallel to the first wall, the other ends of the radiation distribution ribs are perpendicular to the first wall, the multiple radiationstress ribs are located above the radiation distribution ribs and connected with the radiation distribution ribs, and the multiple radiation stress ribs are evenly arranged in a radioactive ray manner from the external corner part. By adoption of the steel bar layer at the external corner part, the advantages that the arrangement manner and the structure are reasonable, the number of steel bar layers is small, the excessive laminated slab pouring thickness can be avoided, cost is saved, and the space requirement is optimized are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a reinforcement layer at an external corner. Background technique [0002] In the prior art, it is usually necessary to add radial ribs at the external corners at the external corners of the special-shaped laminated slabs. The radial ribs at the external corners and the radial distribution ribs in this position are two layers of steel bars. The iron stress ribs and distribution ribs on the top surface of the floor slab are 2 layers of steel bars, a total of 4 layers. Considering that there is a layer of steel bars on the upper chord of the truss bars, there are actually at most 5 layers of steel bars overlapping. Due to the large number of overlapping layers of steel bars, the design tends to ignore the space requirements of the steel bar layout or not to optimize the space requirements. Often, the design plate thickness is too small to meet the requirements, or...

Problems solved by technology

Due to the large number of overlapping layers of steel bars, the design tends to ignore the space requirements of the steel bar layout or not to optimize the space requirements. Often, the design plate thickness is too small to meet the requirements, or the design plate thickness meets the requirements, but the plate thickness is too large. Thick, resulting in waste, the actual situation is the vast majority of the former

The construction is often exposed according to the conventional reinforcement arrangement and design slab thickness pouring, and the reinforcement protection layer does not meet the requirements
