一、问题的提出内浇外砌建筑体系,按内外墙施工的先后顺序不同,形成“先砌后浇”与“先浇后砌”两种施工工艺,前者可使先砌的外砖墙与后浇的混凝土内墙连接比较牢固。在外砌37厘米砖墙的地区,内外墙交接处的构造柱,可以利用砖模与内墙混凝土同时浇筑。外墙圈梁亦不必另行支模,节省了大量的模板和装拆人工,便于施工,而在外砌24厘米砖墙七度抗震设防地区,采用这种工艺施工,往往在内外墙交接处(图1)因为仅留半砖墙作为端模,由于侧压力较大,
First, the problem is put forward in the internal construction of the external masonry building system, according to the sequence of construction of the internal and external walls are different, the formation of “first laying after the pouring” and “first poured after the bricklaying” two construction techniques, the former can be the first to build the external brick wall and The post-cast concrete inner wall is more firmly connected. In the outer wall of 37 cm brick wall, the structural columns at the junction of the inner and outer walls can be cast simultaneously with the brick mold and the inner wall concrete. The outer ring beams also do not need to be supported separately, which saves a large number of formworks and assembling and disassembling labor, and facilitates construction. However, in the externally erected 24cm brick wall seven-degree seismic fortification area, the construction process is often used at the junction between the inner and outer walls (Figure 1). ) Because only half of the brick wall is left as the end model, due to the large lateral pressure,
