Г 溫度伸縮縫的布置——在厂房設計中溫度变化能引起結構变形,結構变形会导致層面和牆的瓦解或使柱弯曲,从而产生附加应力。为了避免这种現象,常在建筑物的縱向和横向上設置溫度伸縮縫。溫度伸縮縫应自簷口起直至基础面,但基础并不切开,使建筑物个別部分只有水平变位,而無垂直变位。溫度伸縮縫区段的極限長度,随溫度升降差的大小、柱子的剛度和吊車梁距地面之高度的不同而异;它与前二者成正比,与后者成反此,根据“鋼結構設計标准及技术規范”的規定,在鋼結構厂房中,当温度伸縮縫的間距不超过下列尺寸时,可不計算溫度作用: 1.采暖的厂房——150公尺; 2.不采暖的厂房及热处理車間——120公尺;
Г Arrangement of temperature expansion joints—Temperature changes in the design of the building can cause structural distortions that can cause the layers and walls to collapse or bend the columns, creating additional stresses. To avoid this phenomenon, temperature expansion joints are often installed in the vertical and horizontal directions of the building. Temperature expansion joints should be from the mouth to the base surface, but the foundation is not cut, so that individual parts of the building only have horizontal displacement, and no vertical displacement. The limit length of the temperature expansion joint section varies with the magnitude of temperature rise and fall, the stiffness of the column, and the height of the crane beam from the ground; it is proportional to the former two and is inversely related to the latter, according to “Steel structure. “Design standard and technical specification” stipulates that in the steel structure workshop, when the gap between the temperature expansion joints does not exceed the following dimensions, the temperature effect may not be calculated: 1. The heating plant - 150 meters; 2. The heating plant and Heat treatment workshop - 120 meters;
