一、 Steel roof truss,
steel grid structure (1) Calculate based on the weight of steel according to the dimensions shown in the design drawing, without deducting the weight of holes, edges, and limbs. The weight of welding rods, rivets, bolts, etc. does not increase.
(2) Irregular or polygonal steel plates shall be calculated based on the area of their regular bounding rectangle.
(3) Steel truss should distinguish between connection forms such as spherical nodes and steel plate nodes.
(4) The unit of measurement is t.
二、 Steel bracket, steel truss
(1) Calculate based on the weight of steel according to the dimensions shown in the design drawing. The weight of holes, edges, and limbs is not deducted, and the weight of welding rods, rivets, bolts, etc. is not increased.
(2) Irregular or polygonal steel plates are calculated based on the area of their bounding rectangle.
(3) The unit of measurement is t.
三、 Steel columns and beams
(1) Calculate based on the weight of steel according to the dimensions shown in the design drawing. The weight of holes, edges, and limbs is not deducted, and the weight of welding rods, rivets, bolts, etc. is not increased.
Irregular or polygonal steel plates are calculated based on the area of their bounding rectangle.
Specifically, it includes solid web columns, hollow web columns, steel pipe columns, steel beams, and steel crane beams. The unit of measurement is t.
(2) The cow legs attached to the steel column are included in the steel column engineering quantity.
(3) The node plates, reinforcement rings, lining pipes, cow legs, etc. on the steel pipe column are incorporated into the quantity of the steel pipe column project.
(4) When designing steel brake beams, steel brake trusses, and car stops, their engineering quantities should be incorporated into the steel crane beam.
四、 Profiled steel plate floor slab, wall panel
Profiled steel plate floor slab: Calculated based on the horizontal projection area according to the dimensions shown in the design drawing, the area of columns, piers, and holes within 0.3m2 is not deducted. The unit of measurement is m2.
Pressed steel sheet wall panel: calculated based on the laying area according to the dimensions shown in the design drawing. The area of holes within 0.3m2 will not be deducted, and the areas of corner wrapping, edge wrapping, and window sill flashing will not be calculated separately. The unit of measurement is m2. Reinforced concrete is poured into the profiled steel plate floor slab, and the concrete and steel bars are calculated according to the relevant regulations for concrete and reinforced concrete.
五、 Steel components
The general calculation rules for steel components are as follows:
(1) Calculate based on the weight of steel according to the dimensions shown in the design drawing. Such as steel supports, steel purlins, steel skylight frames, steel wall frames (including columns, beams, and connecting rods), steel platforms, steel walkways, steel railings, steel funnels, steel brackets, sporadic steel components, etc. The weight of holes, edges, and limbs is not deducted, and the weight of welding rods, rivets, bolts, etc. is not increased.
(2) Irregular or polygonal steel plates are calculated based on the area of their bounding rectangle. The unit of measurement is t.
六、 Metal mesh
Calculate by area based on the dimensions shown in the design drawings, including production, transportation, installation, painting, etc.
