砖混结构以其容易就地取材,造价较低,保温隔热性能好,并且施工简单等优点,在广大农村具有优于其它结构的经济效益和使用功能,因而是目前农房建设中使用最广泛的一种结构形式。 笔者在农房建设管理中发现:多层砖房混凝土构造柱的设计和施工还存在一些问题,现分析如下: 1、钢筋混凝土构造柱的设置不符合现行规范的要求,以七度设防区为例,四层外廊式砖混结构的构造柱设置通病是:(1)没有按规范要求增加一层后的层数设置。(2)较大门窗洞口两侧,大房间内外墙交接处未设置构造柱。(3)楼梯、电梯间四角未设置构造柱。(4)伸缩缝两侧未视为外墙。(5)女儿墙高度超过50厘米未设置构造柱。
The brick-concrete structure has the advantages of easy access to materials on the spot, low construction cost, good thermal insulation performance, and simple construction, etc. It has economic benefits and usage functions superior to other structures in the vast rural areas, and is therefore most used in the construction of rural houses. A wide range of structural forms. The author found in the construction management of rural housing: There are still some problems in the design and construction of the concrete structural columns of multi-storey brick houses. The analysis is as follows: 1. The setting of reinforced concrete structural columns does not meet the requirements of the current regulations. The seven-degree fortification area is For example, the common problem with the configuration of the four-story corridor-type brick-concrete structure is: (1) There is no one-layer setting after adding a layer according to the specification. (2) On both sides of the large door and window openings, there are no structural columns at the junctions of the inside and outside walls of large rooms. (3) There are no structural columns in the four corners of stairs and elevators. (4) Both sides of expansion joints are not considered as exterior walls. (5) The height of the parapet exceeds 50 cm. No structural column is provided.
