楼地面变形缝有什么作用

    变形缝——指为了防止因气温变化、不均匀沉降以及地震等因素造成对建筑物的使用和安全影响,设计时预先在变形敏感部位将建筑物断开,分成若干个相对独立的单元,且预留的缝隙能保证建筑物有足够的变形空间,设置的一种构造缝。
Deformation cracks, in order to prevent because of temperature change, uneven settlement and earthquake factors such as the use of building and safety influence, when the design in advance, disconnect the sensitive parts of the deformation will be building into several relatively independent units, buildings and reserved aperture can guarantee enough deformation space, set up a kind of structural fractures.
    变形缝包括了伸缩缝 ( 温度缝〉、沉降缝和抗震缝。
Seam deformation joints including the expansion joints (temperature >, settlement joint and aseismatic joint.
    伸缩缝: 建筑构件因温度和湿度等因素的变化会产生胀缩变形。为此,通常在建筑物适当的部位设置竖缝,自基础以上将房屋的墙体、楼板层、 屋顶等构件断开,将建筑物分离成几个独立的部分。
Expansion joints, construction component due to factors such as temperature and humidity changes can produce swell-shrink deformation.To this end, usually in the area of building appropriate setting vertical seam, above since the foundation of the building wall, floor, roof and other components are disconnected, will break into several independent parts of the building.
    沉降缝:上部结构各部分之间,因层数差异较大,或使用荷重相差较大;或因地基压缩性差异较大,总之一句话,可能使地基发生不均匀沉降时,需要设缝将结构分为几部分,使其每一部分的沉降比较均匀,避免在结构中产生额外的应力,该缝即称之为“沉降缝”。
Settlement joint: between all parts of the upper structure, due to the layer number of differences, or the use of load is large;Or because of differences in foundation compressibility, in a word, may make the foundation uneven settlement occurs, need slotting structure can be divided into several parts, each part of the settlement is evener, avoid generate additional stress in the structure, the seam is called "settlement joint".
    防震缝:它的设置目的是将大型建筑物分隔为较小的部分,形成相对独立的防震单元,避免因地震造成建筑物整体震动不协调,而产生破坏。
Shockproof seam: set the purpose of it is will be large building divided into smaller parts, form the relatively independent shock unit, avoid vibration not harmonious whole building caused by the earthquake, and destructive.
