Fastener type steel pipe scaffold strength is generally how much
The principle of the same host, in terms of thin words, air-source hot water machine does not do the use of refrigeration, and its own hot water function is ideal, because the design process to consider the heat exchanger size and heat pump heat exchanger how much or A little gap between the long river thanks to the degree of petals. Air can be used as hot water is certainly very good, air source as air conditioning heating and cooling is very ideal. But the system integration is more important than the device itself, because the system design is not good host performance can not start. Air to one machine is relatively simple to use, the need for strict design, and the integration of the system is very important to install, resulting in equipment performance does not come out, or always complain about the manufacturers. Summary of the difference is the same system principle, the system is not the same installation.
Yes, also known as big core board. Mainly to make the interior of the decorations, such as the interior of the door. The outside should be affixed to a layer of decorations can, so can not directly on the big core board to paint. There are differences between the different regions, but roughly between 65-100 yuan each.
5m The center of the joint to the main node of the distance should not be greater than the step 1/ pole and large crossbar must be fastened with fasteners, shall not be set or omitted The position of the joint, the adjacent rod to be staggered, and arranged in different steps, staggered distance greater than or equal to 500mm, the connector from the vertical horizontal bar distance of less than or equal to 1/3 steps, the use of docking, not lap When you start to set up the pole, you should set up a straddle every 6 span, until the wall is installed after the stability, according to the situation removed Second, the vertical horizontal bar (large cross bar) vertical horizontal bar with docking fastener connection staggered arrangement, two adjacent horizontal horizontal rod joints should not be set in the synchronous cross, the adjacent joints in the horizontal direction of the distance of not less than 500mm , The distance from the center of the joint to the nearest main node is not more than 1/3 of the longitudinal distance The horizontal deviation of the same row of large bars is no greater than 1/250 of the total length of the scaffold and is not greater than 50mm
