What are the roof pressing steel plate structures?
The selection of the profiled steel plate should take into account the roof slope. When the slope is small, because the roof drainage is not smooth, the high corrugated roof plate should be used as far as possible. The included Angle between the web of the profiled steel plate and the horizontal plane of the flange should not be less than. ⒊ Shaped steel plate should be used long foot plate, in order to reduce the number of plate transverse lap, is conducive to roof waterproof. The transverse lap of the profilled steel plate should be reliably connected with purlin. The lap length should meet the specification requirements. The lap length should not be less than 350mm for high corrugated profilled steel plate with wave height greater than 70mm, and the lap length should not be less than 250mm for low corrugated profilled steel plate with wave height less than 70mm. 5. There are different ways of side connection of profiled steel plates, refer to Section 4 of this chapter for details. In order to prevent roof leakage, if possible, the use of hidden button connection. When the roof panel side lap, the lap width should depend on the shape and specification of the profile steel plate, generally not less than half wave, the lap direction should be consistent with the dominant wind direction. For low corrugated profile-shaped steel plates with wave height less than 70mm, no fixing bracket is required, while for high corrugated profile-shaped steel plates with wave height greater than 70mm, a fixing bracket is required. 6. When transverse and lateral connection of pressing steel plate, there must be reliable connection to prevent dislocation and sliding of roof plate. 7. Considering the poor performance of domestic sealing material and easy to aging and cracking, the connecting piece is set in the crest of the wave as far as possible in order to waterproof.
Is it possible to install water stop steel plate (soil roof) for the roof after pouring?
The roof after pouring belt, before pouring can be set water stop steel plate, in the case of construction conditions allow can also set flexible water stop belt. Because the post-pouring belt is a construction node that is used for pouring after a specified time, waterproof measures must be taken before pouring in the parts with waterproof requirements, such as the roof, so as to avoid roof leakage affecting the construction quality. The installation of water stop steel plate or water stop belt must be installed according to the specification, and both sides are fixed. Concrete can be poured after the inspection process is qualified.
Galvanized corrugated steel plate compression strength is how much?
SPHC Tempering chemical Composition (mass fraction) (%)
C: 0.12 or less
Mn: 0.50 or less
Si: 0.30 or less
S: 0.040 or less
P: 0.035 or less
Mechanical properties of SPHC steel
Tensile strength (σ B /MPa) : ≥270
Elongation (δ5/%) : ≥33 (steel thickness or diameter ≤16mm), ≥32 (steel thickness or diameter > 16-40 mm)
Main characteristics of SPHC steel
It has high plasticity, toughness and welding performance, good pressure machining performance, but low strength.
SPHC steel application examples
Used for manufacturing anchor bolt, ploughshare, chimney, roof board, rivet, low carbon steel wire, thin plate, welding pipe, pull rod, hook, bracket, welding structure, etc. Roll sheet and wire rod. Cold and hot rolled thin steel plates and galvanized, tinned and plastic composite thin steel plates made from them are widely used in roofing plates, decorative plates, general dust removal pipes, packaging containers, iron barrels, instrument cases, switch boxes, protective covers, train carriages and so on. Wire rod is more cold drawn into low carbon steel wire or galvanized into galvanized low carbon steel wire, used for binding, tension fixed or used as wire mesh, rivets and so on.
