避免冷库吊装发生变型的加固措施
2018-5-23 15:28:22

吊装时根据排管长度重量确定吊点数量和位置,起吊前应预先将楼板上预埋螺栓校正好。排管的吊装应由一人智慧,动作一致,以保证整体排管水平上升。当排管上升到预定位置时,上好预埋螺母.

The number and location of the lifting points should be determined according to the weight of the row length before lifting. The pre embedded bolts should be corrected in advance before lifting. Hoisting should be done by one person with wisdom and action so as to ensure the overall level of platoon management rises. When the row pipe rises to a predetermined position, a good embedded nut is placed.

排管吊装的螺栓,在拧紧螺母后应伸出螺母四个螺距,在拧紧螺栓时校正排管的水平及坡度。排管的水平和坡度可在吊装螺栓处加垫圈来调整。

Bolts for hoisting pipes should be extended after tightening the nut. The four pitch of the nut should be extended, and the level and slope of the pipe should be corrected when the bolt is tightened. The level and slope of the pipe can be adjusted with the washer at the lifting bolt.

蒸发排管通常采取整体吊装。当蒸发面积较大时,其本身的刚性较差,为避免吊装时发生的变型,必须采取加固措施。加固的方法除按样图规定安装好各排管的角钢支教和吊装支架外,在排管底部还要利用槽钢或工字钢再做一吊装托架。

The evaporating tube is usually hoisted as a whole. When the evaporation area is large, its rigidity is poor. In order to avoid the deformation during lifting, it is necessary to take reinforcement measures. In addition to the installation of corner steel support and hoisting support of each row of pipes according to the sample drawing, it is also necessary to make use of channel steel or I-steel at the bottom of the pipe to do a hoisting bracket.

排管的安装有一定的基本技术要求,墙排管中心与墙壁内表面间距离不小于150mm,顶排管中心(多层排管为上层管子中心)与库顶距离不小于300mm.

There are some basic technical requirements for the installation of the pipe row. The distance between the wall row center and the inner surface of the wall is not less than 150mm, and the center of the top row tube (the multilayer pipe is the upper pipe center) and the distance from the top of the library is not less than 300mm.

(1)步骤:连接水管→铺设加热丝→检查水泄漏→绝热

(1) steps: connect the water pipe, lay the heating wire, check the water leakage, adiabatic.

(2)管道安装前必须将管内的污物及锈蚀清除干净,安装停顿期间对管道开口应采取封闭保护措施。

(2) the contaminants and rust must be removed before installation of pipelines. Closed protection measures should be adopted for pipeline openings during installation.

(3)排水管在库内有效距离越短越好,水平管应坡向排水口坡度为1/100至1/50.

(3) the shorter the effective distance of the drainage pipe in the reservoir is, the better the slope of the horizontal pipe should be from 1/100 to 1/50..
