What method can be tested for the thermal conductivity of polystyrene foam?
Zibo type construction fastener, by the two holes in the diameter of the child is significantly different, the female fastener riveting from the edge of the stump of the dwarf dwarf dog dog chuhua, two fasteners on the lower cover are steel stamping parts , The upper cover, the lower cover has a stiffener, the middle part of the lower and lower cover inward arc protrusion, the arc-shaped convex surface and the upper and lower cover on both sides of the same cylindrical surface, The nut size on the pieces is the same. The fastener is used to build construction scaffolding, building fence, planting greenhouses, etc., can be connected to different diameter pipe, can be rotated angle, wide range of applications, and the fastener weight, bending strength and good steel, , Easy to use. A angry bird
The effect is the same, but in general or paste inside the more
Columns: Outer wall scaffolding outside the main column longitudinal spacing are 1m, the vertical column spacing of the rod position should be staggered in different steps, and the distance between the large bar should not be greater than one-third of the distance, The pole and the large bar must be fastened with a right-angled fastener to be set or omitted. When the pole is placed on the ground, the foot of the pole shall be increased by more than 200 × 200. It shall be enlarged from the ground at 250mm and the outer surface shall be set at every 12m pitch. Support, angle to 45 ° -55 ° range. Working layer: width of 800mm, the bridge all set the steel pipe as a foot, the first step from the first 1.95m, steel pipe spacing of 2m, two steel pipe between a small bar. Outside the column between the steps set up a steel pipe protection bar, the first floor and the building to use dense mesh safety net, each layer of the working layer of the outer column should be set at the bottom of the 180mm high skirting board. Outside the scaffolding outside the column with a qualified dense mesh safety net.
