Key Points In The Planning And Management Of Chemical Laboratories

Aug 27, 2018

First, the form of the chemical laboratory

(1) Small space form The laboratory with standard modulus as the basic unit, suitable for research laboratories, can provide researchers with a quiet working environment. The disadvantage is that the contact and mutual understanding between the researchers in each room is not as good as the mutual understanding. Space laboratory is convenient.

(2) Medium or large space form, which is a large room composed of multiple basic units. This large space is not suitable for some research laboratories because of mutual interference.

(3) A large space with a partition, which uses a partition wall to even divide a large room into small spaces with a fume hood or other auxiliary experimental furniture, so this form is actually in between the above two forms. a compromise between forms. This form is conducive to the use of space, enhances the interrelationship among researchers, and has the advantages of convenient pipeline installation and easy management.

(4) The flexible space form can generally be considered from the following aspects: load-bearing partition walls, especially cross-walls, hope to be as small as possible, if possible, frame structure is more advantageous; floor design The load should be determined according to the specific conditions, but it should not be taken low, and the fixed test bench should be set as low as possible. Even the fixed test bench should be designed to be composed of standard-scale prefabricated components to facilitate re-assembly. Pipeline maintenance wells should be adequately configured to avoid opening holes in the floor in the future. Flexible space, in two forms. The first is a flexible space with a moving partition wall. This kind of movable partition wall has a special structure, which is convenient for assembly and disassembly, but the pipeline along the wall must be clearly applied. At the same time, the pipe network system must have great flexibility, otherwise the superiority of the movable partition wall is not prominent, because the change of the non-load-bearing partition wall is usually easier, and the pipeline change is more difficult. The second is a general flexible space. This is a large space. From the flat top, the wires and the service supply hose can be led down. The ground can be connected to the sewer pipe, so the test bench with the water basin and the fume hood are movable.

二、实验台的布置方式

  在自然采光里,不宜平行于有采光窗的外墙,因人面向窗子时有眩光,而背向时,台面产生阴影。

  (1)设置岛式中央台时应考虑管线的处理,下面列出几种情况:

  ①地板上挖地沟加盖板,存在渗漏、积液问题,但便于维修;

  ②地板直埋式,当出现问题时,需要凿开检修更换,影响周围;

  ③穿楼板存在渗漏问题,楼下不宜设置高精密仪器,太高检修不便;

  ④悬吊式,太难看,影响美观。

  (2)建议设置半岛式中央台(即边中央台),优点是易于埋藏管线。

  (3)实验台之间需有间距。

  三、实验台的尺度要求

  (1)实验台的长度分配:一般实验室1.2米/人;有机实验室1.5米/人;

  (2)台面高度:中国850mm;美国、西德900~920mm;日本800mm;

  (3)台面宽度:≥600mm,尽量不要超过750mm(板材最大利用率);

  (4)双面即中央台台面:1500mm。

  四、实验台的组合

  (1)实验台的台面尽量采用整片台面、标准柜体组合,减少台面的拼缝,保证实验台的整体美观,调试方便并可提高施工进度;

  (2)伸膝凹口宽度:600~1100mm;

  (3)试剂架:深度能并列放置两瓶中型试剂瓶(500ml)为合适。通常为200~300mm,分上下两层;

  (4)靠墙边台用试剂架取:200m;

  (5)中央台用试剂架取:300mm。

  五、实验室通风管路规划及测量要求

  绘制线条图:在同客户规划设计通风系统方案时,一定要得到工程相关现场测量数据:实验室房间的平面尺寸、所处的楼层、楼层净空高度、房间横梁与地板的高度、天花板与地板的高度、通风产品在房间的布局位置尺寸、墙体窗户的位置的尺寸、天台所处的楼层、风机在天台上安放的位置尺寸、客户要求排风管道的走向、排风井的截面尺寸等。
