Q:Air conditioning machine work when the sound is too much reason
Many of the good quality of the model, of course, bear some of the larger. Common scaffolding brackets are U-type care, "construction fastener steel scaffold safety technical regulations" (JGJ130-2011) provides "adjustable support bearing capacity design value should not be less than 40kN, support plate thickness should not be less than 5mm ", the general calculation using 30kN. Not to say how fast buckle steel scaffold can bear the load, but according to how much load to calculate how scaffolding erection. Need to be calculated. In the "construction of fasteners steel scaffold safety technical specifications" provides instructions. Double fastener (anti - skid) bearing capacity design value 3.2KN. Right angle fastener, rotary fastener (anti-skid) bearing capacity design value 8KN.
Q:What is the whole heat exchange fresh air ventilator?
(GJG130 - Fan Jutang Duanjie Daojie Juejiao 2001) will be replaced by (GJG130-2011) is expected to begin the implementation of the construction of this year, the construction of fastener steel scaffolding safety technical specifications (GJG130), the construction of fastening steel pipe scaffolding safety technical specifications (GJG130- -2011)
Q:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
Polystyrene should not be polycyclic aromatic. Polycyclic aromatic groups generally refer to aromatic groups when multiple benzene rings are used. Not all of the hydrocarbon chemical products are carcinogenic, and our bodies are producing hydrocarbon compounds all the time. Polystyrene carcinogenicity is small. General benzene ring on the more substituents, the toxicity is relatively small, such as toluene is less than the toxicity of benzene. Of course, there are many compounds with benzene ring, so there are a lot of scholars to study with our body creatures do not meet the quality of raw materials to do the polymer, such as lactic acid production of polylactic acid, but the current Can be put into use much.
Q:Space blowing wind is not cold how is it?
The general level of more than 12 layers when you need to use.
Q:Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
You are talking about the construction measures it is not the house measures it, because the house has a construction of Huohuohuohuo number of leather and bronze sculpture drawings and specifications, high-rise building scaffolding should be lightning protection measures, that is, under the scaffolding around Reliable grounding (not less than four times, not less than 16 square copper core BV line), if it is pick plus, and the house can be connected to the pressure ring. Tower crane I will not say, upstairs has been said.
Q:Air to water heater host and air conditioning host is not the same
You can try asphalt! Is the kind of paving the way! Very useful!
Q:Ventilation is very good, why still have to install fresh air system
You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%
Q:Home 2 air conditioning is the cooling of electricity or heating electricity? How much power is spent in hours
No, polycyclic aromatic should be anthraquinone This is certainly not all of the hydrocarbons are carcinogenic
Q:External wall insulation method of operation There are several combinations of materials
Seeking the existing building construction specifications Daquan! The The @ .com
Q:Single cold air conditioning function can not change the cold and warm?
So good, then you recommend more. Give an address. You are not layman, too modest.
