In the construction, the commonly used components made of reinforced concrete are beams, slabs, walls, columns, etc. Because these components play different roles in the construction, the steel bars in their internal configuration are also different.

　　（一）梁内钢筋的配置

　　(1) Allocation of reinforcing bars in beams

　　梁在钢筋混凝土构件中属于受弯构件。在其内部配置的钢筋主要有：纵向受力钢筋、弯起钢筋、箍筋和架立筋等。

　　Beams belong to flexural members in reinforced concrete members. The main reinforcement configurations are longitudinal force reinforcement, bending reinforcement, stirrups and erecting reinforcement.

　　1、纵向受力钢筋：布置在梁的受拉区，主要作用是接受由

　　1. Longitudinal stress reinforcement: arranged in the tension zone of the beam, the main function is to accept from

　　弯矩在梁内产生的拉力。

　　The tension produced by the bending moment in the beam.

　　2、弯起钢筋：弯起段用来接受弯矩和剪力产生的主拉应力，弯起后的程度段可接受支座处的负弯矩，跨中程度段用来接受弯矩产生的拉力。弯起钢筋的弯起角度有45?和60?两种。

　　2. Bending reinforcing bar: Bending section is used to accept the principal tension stress caused by bending moment and shear force, the degree section after bending can accept the negative bending moment at the support, and the mid-span section is used to accept the tension caused by bending moment. The bending angle of the steel bar is 45? And 60? Respectively.

　　3、箍筋：主要用来接受由剪力和弯矩在梁内产生的主拉应力，固定纵向受力钢筋，与其它钢筋一同构成钢筋骨架。钢箍的方式分启齿式和封锁式两种。普通常用的是封锁式。

　　3. Stirrups: They are mainly used to accept the principal tension stress produced by shear force and bending moment in the beam, fix the steel bar under longitudinal force, and form the steel bar skeleton together with other steel bars. There are two ways of steel hoop: open teeth type and blockade type. Commonly used is the blockade type.

　　4、架立筋：设置在梁的受压区外缘两侧，用来固定箍筋和

　　4. erecting reinforcement: set on both sides of the outer edge of the compression zone of the beam to fix the stirrups and stirrups

　　构成钢筋骨架。

　　The steel bar skeleton is formed.

　　（二）板内钢筋的配置

　　(2) Allocation of reinforcing bars in slabs

　　板在钢筋混凝土构件中属于受弯构件。板内配置有受力钢筋

　　The slab is a flexural member in reinforced concrete members. The plate is equipped with stressed steel bars

　　和散布钢筋两种。

　　Two kinds of steel bar are used.

　　1、受力钢筋：沿板的跨度方向在受拉区配置。单向板沿短向布置，四边支承板，沿长短边方向均应布置受力筋。

　　1. Forced reinforcement: along the span direction of the slab in the tension zone. One-way slabs are arranged along the short direction, supporting slabs on four sides, and stress bars should be arranged along the long and short sides.

　　2、散布筋：布置在受力筋的内侧，与受力筋垂直。散布筋的作用是将板面上的荷载平均地传给受力钢筋，同时在浇注混凝土时固定受力筋的位置，且能抵御温度应力和收缩应力。

　　2. Dispersing tendons: They are arranged on the inner side of the stressed tendons and are perpendicular to the stressed tendons. The function of distributed reinforcement is to transmit the load on the slab surface to the stressed reinforcement on average, and fix the position of the stressed reinforcement when pouring concrete, which can resist the temperature stress and shrinkage stress.

　　（三）柱内钢筋的配置

　　(3) Configuration of reinforcing bars in columns

　　柱在钢筋混凝土构件中起受压、受弯作用。柱依据外形不同有普通箍筋柱和螺旋箍筋柱两种。柱内配置的钢筋有纵向钢筋和箍筋。纵向钢筋主要起接受压力的作用，箍筋起限制横向变形，有助抗压强度进步，对纵向钢筋定位并与纵筋构成钢筋骨架的作用。柱内箍筋应采用封锁式。

　　Columns act as compressive and flexural members of reinforced concrete. There are two kinds of columns according to their shapes: ordinary stirrup column and spiral stirrup column. The steel bars in the column are longitudinal steel bars and stirrups. Longitudinal reinforcing bars are mainly used to accept pressure. Stirrups restrict transverse deformation, help to improve compressive strength, locate longitudinal reinforcing bars and form reinforcing bar skeleton with longitudinal reinforcing bars. The stirrups in columns should be blocked.

　　（四）墙内钢筋的配置

　　(4) Allocation of reinforcing bars in walls

　　钢筋混凝土墙内依据需求可配置单层或双层钢筋网片，墙体钢筋网片主要由竖筋和横筋组成。竖筋的作用主要是接受程度荷载对墙体产生的拉应力，横筋主要用来固定竖筋的位置并接受一定的剪力作用。在设置双层钢筋网片的墙体中，为了保证两钢筋网片的正确位置，通常应在两片钢筋网片之间设置撑铁。

　　Reinforced concrete walls can be equipped with single or double-deck steel mesh according to the demand. The steel mesh of walls is mainly composed of vertical and transverse reinforcement. The main function of the vertical reinforcement is to accept the tension stress of the wall caused by the degree of load, while the transverse reinforcement is mainly used to fix the position of the vertical reinforcement and accept a certain shear force. In order to ensure the correct position of the two reinforcing steel meshes in the wall with double-layer reinforcing steel meshes, it is usually necessary to set bracing iron between the two reinforcing steel meshes.
