空旷砖房的特点是有较大的空间,系砖墙(柱)承重的结构。从功能上看,主要包括影剧院、礼堂、俱乐部、大食堂等公共建筑,搞好这类建筑的抗震加固非常重要。由于使用上的要求,这类建筑一般分为前厅、中厅(观众厅)、后厅和侧厅(休息厅)四部分。前厅多为砖混或内框架结构,一般为二、三层;中厅为木、钢及少数为钢筋混凝土屋 Empty brick houses are characterized by a relatively large space, which is a load-bearing structure of brick walls (pillars). From a functional point of view, it mainly includes public buildings such as theaters, auditoriums, clubs, and large canteens. It is very important to do a good job of earthquake-resistant reinforcement of such buildings. Due to the requirements for use, such buildings are generally divided into four parts: the front hall, the middle hall (audience hall), the rear hall, and the side hall (lounge). Most of the front hall is a brick-concrete or inner frame structure, usually two or three floors; the middle hall is made of wood, steel, and a few are reinforced concrete houses.
