In the last issue,we talked about the three practical partition systems.In this issue,let's talk about the unified ,and sound insulation walls of the three applied partition walls.
一、The wall which can reach 37-66 decibels.
High Sound Insulation Household Partition Wall
height：3m
Sound insulation grade：60dB
Fireproof：1-2h
2、Shaft wall system，CH-type keel increase the fireproof performance of the wall.
In the steel structure buliding,the shaft wall system is composed of elevators,and other parts.It is suggested that the CH keel shaft wall system specially developed by Dachen buliding materials should be adopted.The gypsum board is installde with self-attack nail on the outside of the parallel road,and a layer of 25mm thick or double-layer 12mm thick high-grade water-resistant and refractory gypsum board is in serted directly on the inside of the parallel road,which solves the problemof in convenient installation of the inner slate of the well track.The addition of rock wool to the CH keel skeleton can increase the fire prevention performance of the well wall.
System：CH series partition keel+25MM fireproof gypsum+12MM fireproof+glassfiber
Function：high efficiency fire prevention for more than 2hours,good strength，stifffnessand anti-hit,fast industrial
Application：All kinds of elevator,elevator common,service pipe shaft
3、Veneer wall system,directly install gypsum board,effectively correct uneven wall
System advantage：adjustment distance free
