Nowadays, steel mesh is more and more widely used. Here is a brief introduction to the difference between steel mesh and steel bone:
1. Steel mesh refers to the prefabricated or welded steel mesh (mainly used for slab or wall) directly lifted during construction.
2. Steel bone is also pre-stressed. It is usually pre-stressed in brick and concrete structures (structural columns, beams, etc.). Is the whole hoisting directly belong to steel bone?
3. It is emphasized that the reinforcement refers to the distance between the steel mesh or steel framework and the site: the distance between them refers to the same line of reinforcement, and the row spacing refers to the distance between different lines of reinforcement, such as: a. The row spacing of plate bearing steel bars refers to the distance between the lower row and the bar first row (if any) or negative moment steel bars. b. The distance between the bars on the column refers to the distance between the bars on the same side, while the distance between the bars on the column refers to the distance between the bars on different sides. (the determination of column spacing and row spacing shall be set as reference for either side, and the spacing and row spacing can be exchanged for different references) C. the distance between the beam reinforcement spacing and the horizontal plane parallel to a row is mainly the difference between the reinforced steel rows and the row reinforcement, d. The reinforcement spacing of the wall stress and the row spacing determine the equivalent double-layer slab reinforcement erection. The same vertical or horizontal reinforcement is helpful for the reinforcement in the mesh. Is the distance between different mesh spacing helpful for the reinforcement? Row spacing?
One word: the inspection lot inspection should be distinguished from the overall lifting prior help (filling steel mesh, steel frame), or the website help Mr. (force enhancing filling). In addition to filling in the inspection record truthfully, it should also check whether the spacing and row spacing meet the requirements. The specific inspection items are not limited to the inspection items of the steel bar installation inspection lot (but must be checked), forming some specification related items, It shall also be checked (including inspection batch checklist of steel raw materials, inspection batch checklist of steel mesh reinforcement processing, inspection batch checklist of reinforcement connection test and inspection checklist of formwork installation for axis position, perpendicularity, thickness of protective layer, etc.).
