砖和非预应力(或预应力)钢筋混凝土梁,前者主要用于砌筑墙体,而后者则主要用于承受荷载的结构构件上。随着科学技术的不断发展和提高,这二者的用途也在不断的扩展。下面就我们在国外施工的小截面钢筋混凝土梁和空心砖结构体系的施工方法做一介绍。 一、钢筋混凝土小梁和空心砖的概况 (一)钢筋混凝土小梁的种类 从力学的角度来讲,这种小梁可分为两类:一类 Bricks and non-prestressed (or prestressed) reinforced concrete beams, the former are mainly used for masonry walls, while the latter are mainly used for structural members that bear loads. With the continuous development and improvement of science and technology, the use of the two is also expanding. The following is an introduction to the construction methods of the small-section reinforced concrete beams and hollow brick structures that we have constructed abroad. I. Overview of reinforced concrete girders and hollow bricks (I) Types of reinforced concrete girders From the mechanical point of view, such trabecules can be divided into two categories:
