Simple algorithm for steel structure sandblasting and rust removal engineering quantity in final acc

Wouldn't you know the amount if you dismantle the steel structure again?

The engineering quantity of steel structure steel columns, steel beams, and purlins brushing anti-rust paint is calculated according to the area of the component, and the rust removal is calculated by weight. Calculated according to the theoretical weight of the steel structure. The amount of anti-rust paint and rust removal of steel structure can be calculated according to the specific size of each component of the steel structure marked in the construction drawings, and then the corresponding rust removal and painting quota can be set in Liaoning area.

Note: The physical parameters can be seen on the paint bucket or with the paint manual.

The engineering quantity calculation unit of steel structure antirust paint and epoxy zinc-rich primer and general paint is 100kg, and the oil brushing sub-item in the metal structure division of the 08 building quota is implemented; Fluorocarbon paint and other high-grade decorative topcoats implement the metal surface paint sub-item under the metal structure under the paint and coating division in the 08 decoration quota, the engineering quantity calculation unit is m2, and the engineering quantity of the coating is the area.

Summary. The equipment is divided into diameter sizes, and sub-items are divided into inner and outer walls, which are calculated in units of "10". Pipes are divided into sub-items by inner and outer walls, calculated in units of "10".

Metal structures are calculated in units of "100kg" according to their mass. The gas cabinet is divided into sprayed quartz sand and river sand, which are divided into sub-items according to the sink wall plate, sink bottom plate, middle cover plate and metal structure, except for the metal structure calculated in the unit of "100kg" by mass, the rest are calculated in units of "10" according to the area.

The equipment is divided into diameter sizes, and sub-items are divided into inner and outer walls, which are calculated in units of "10". The pipeline is divided into sub-items according to the inner limb inspection and outer wall, and is calculated in units of "10". Metal structures are calculated in units of "100kg" according to their mass.

The gas cabinet is divided into sprayed quartz sand and river sand, respectively, according to the sink wall plate, the sink floor plate, the middle cover plate, and the metal structure is divided into sub-items, except for the metal structure calculated according to the mass of "100kg", the rest are calculated according to the area of "10".

If your question has been solved, please give a 5-star thumbs up. Blindly there is a risk in the Tan Hall and you still need to see more, I hope to praise my help for you, and look forward to communicating again to answer for you

Summary. The equipment is divided into diameters and sub-items according to the inner and outer walls, which are calculated in units of "10 m2". The pipeline is divided into sub-items by inner and outer walls, which are calculated in units of "10 m2".

Metal structures are calculated in units of "100kg" according to their mass. The gas cabinet is divided into sprayed quartz sand and river sand, which are divided into sub-items according to the sink wall plate, sink bottom plate, middle cover plate and metal structure, except for the metal structure calculated in units of "100kg" by mass, the rest are calculated in units of "10m2" according to the area.

Just like doing oil Zi's lacquer, it is generally calculated by the square, and the same, if the pieces are all the same specification of steel, as you said, it is also possible to calculate in tons, but it should be a ton with a fixed number of squares, and the psychological side of the processing should have a bottom.

The equipment distinguishes the size of the cherry tree in diameter, and divides the sub-items into the order Acacia spine according to the inner wall and the outer wall, which is calculated in units of "10 m2". The pipeline is divided into sub-projects according to the inner and outer walls, and is calculated in units of "10 m2". Metal structures are calculated in units of "100kg" according to their mass.

The gas cabinet is divided into sprayed quartz sand and river sand, which are divided into sub-items according to the sink wall plate, sink bottom plate, middle cover plate and metal structure, except for the metal structure calculated in units of "100kg" by mass, the rest are calculated in units of "10m2" according to the area.

Thank you. Now doesn't it mean that it is calculated by square meters.

You can ask the local area what is calculated, it is more reliable.

1) Workpiece coating and workpiece bonding pretreatment.

Sandblasting can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic schema (that is, the so-called rough surface) on the surface of the workpiece, and can achieve different degrees of roughness by changing the abrasives of different particle sizes, which greatly improves the adhesion between the workpiece and the coating and plating. Or make the adhesive bond stronger and better quality.

2) Cleaning and polishing of the rough surface of castings and forgings and workpieces after heat treatment.

Sandblasting can clean all dirt (such as oxide scale, oil and other residues) on the surface of castings and forgings and heat-treated workpieces, and polish the surface of the workpiece to improve the finish of the workpiece and play the role of beautifying the workpiece.

Sandblasting cleaning can expose the uniform metal color of the workpiece, make the appearance of the workpiece more beautiful, and achieve the effect of beautification and decoration.

3) Burr cleaning and surface beautification of machined parts.

Sandblasting can clean the tiny burrs on the surface of the workpiece, and make the surface of the workpiece more flat, eliminate the harm of burrs, and improve the grade of the workpiece. And sandblasting can make a small fillet at the junction of the surface of the workpiece, making the workpiece appear more beautiful and more precise.

4) Improve the mechanical properties of parts.

After sandblasting, mechanical parts can produce uniform and fine concave and convex surfaces (basic schema) on the surface of the parts, so that the lubricating oil can be stored, improve the lubrication conditions, reduce noise and improve the service life of the machinery.

5) Decorative effect.

Polishing the surface of various workpieces to make the surface of the workpiece more beautiful.

Make the workpiece smooth and non-reflective requirements.

Look at the amount of materials per ton of steel structure, the amount of steel rust remover, the amount of time, and the wages of workers.
