多层保温板拼缝密封技术在某冷库TPO单层屋面系统中的应用

Application of Joints Sealing Technology for Multi-layer Insulation Board in TPO Single-ply Roof System of Some Refrigeration Storage

某冷库TPO单层屋面系统采用防火墙处预留马牙槎发泡缝处理做法,解决了冷库屋面多层保温板平直缝及防火墙与发泡剂平直接缝带来的直线跑冷问题,增加了冷库防火墙处保温效果,降低了冷库内天花板跑冷严重造成垂挂式冰棱的危险。

The TPO single-ply roof system of some refrigeration storage adopted foaming treatment for the reserved toothed joints with the firewalls. It solves the problem of cold loss from the straight seams of the multi-layer insulation board and the straight seam between the firewalls and foaming agent. In this way, the insulation effect at the firewall areas of the refrigeration house is increased, and the danger of hanging icicles due to serious cold loss inside the ceiling is reduced.
