Problems solved by technology

The designed steel bar spacing is easy to satisfy in rectangular slabs, but circular (arc, ring, sector) slabs cannot meet the requirements due to the difference in circumferential spacing between the near center and far center. If the steel bars are still arranged according to the rectangular slab, although the steel bar spacing can be Satisfied, but the anchoring direction and other stress conditions of the steel bars in the slab will change, which still does not meet the design requirements

Embodiment

[0013] Such as figure 1 As shown, a method for arranging steel bars in a shaped plate, the steps are as follows:

[0014] Step 1. Steel bar classification: Divide the steel bars into radial steel bars 1 and circumferential steel bars 2. The principle is that the radial steel bars 1 are radially distributed from the center of the circle, and the circumferential steel bars 2 are arranged around the center of the circle, perpendicular to the radial steel bars.

[0015] Step 2. Determination of the shape plate: determine whether the shape plate is a one-way slab or a two-way slab. If it is a two-way slab, radial steel bars or circumferential steel bars can be placed underneath; Steel bars, hoop bars.

[0016] Step 3. Steel bar installation: Arrange radial steel bars on the farthest end plate edge from the center of the shaped plate. The steel bar spacing is the design spacing. This design spacing becomes smaller and smaller in the direction close to the center of the circle. When...

Abstract

A shaped plate steel bar arranging method is disclosed. The method is characterized by including 1) a step of steel bar sorting, 2) a step of shaped plate determining and 3) a step of steel bar installation. Steel bars are arranged according to a structure form and stress states, the using number of the steel bars is reduced on the premise of meeting stress and distance requirements on the steel bars in a design to the utmost. Steel bar blanking is simple in form and few in variety specification, and therefore workers can understand easily during construction and operation is simple.

Description

technical field [0001] The invention relates to a method for arranging steel bars for circular slabs, arc-shaped slabs, annular slabs or fan-shaped slabs. Background technique [0002] In modern engineering design, stadium buildings, other public buildings, and industrial pools and other buildings and structures, due to their own shape and use function requirements, the overall shape is often designed as a circle (arc, ring, fan) shape, and the corresponding circles often appear. (arc, ring, fan) shaped plate. In the reinforcement design of this type of slab, the general designer only puts forward design requirements for the grade, diameter, and spacing of the slab reinforcement, and does not make requirements for the distribution method of the reinforcement. The designed steel bar spacing is easy to satisfy in rectangular slabs, but circular (arc, ring, sector) slabs cannot meet the requirements due to the difference in circumferential spacing between the near center and f...
