在改革开放和发展市场经济的形势下,有许多临街住宅开洞设店,拆墙换梁,扩大通室。我公司为扩大培训场所曾进行了两处教室改造工程,既保证了使用又无碍建筑安全。现将具体做法介绍如下。一、拆墙位置选择拆墙换梁即将单间或双间的横隔墙拆除,横穿钢梁,由纵墙承受原有荷载。平面选择应注意以下几点:1.尽量选择在房屋中间,使墙体的抗震刚度尽量对称。必须避开抗震刚度较薄弱的部位,如楼梯间对应的横墙或端墙相邻的横墙等。
Under the situation of reform and opening up and the development of a market economy, there are many street-level houses that have opened stores, replaced walls, replaced beams, and expanded the general room. Our company has carried out two classroom renovation projects for the purpose of expanding the training site, which not only guarantees the use but also does not hinder construction safety. The specific practices are described below. First, the location of the demolition wall The demolition wall replacement beam is to be demolished in a single or double transverse partition wall, across the steel beam, the vertical wall to bear the original load. Plane selection should pay attention to the following points: 1. Try to choose the middle of the house so that the seismic stiffness of the wall is as symmetrical as possible. Must avoid areas where seismic stiffness is weak, such as the corresponding transverse wall of a stairwell or the adjacent horizontal wall of the end wall.
