What is the general rebar loss rate? What is the loss of general rebar?

The loss of steel bars is generally calculated according to the quota, and the domestic loss of steel bars is generally about 3%.

Calculation method of rib loss rate: rib loss rate = (total amount of raw materials and total amount of material list) total amount of material list * 100% When the total amount of raw materials is 100 tons (the remaining is 0) and the total amount of material list is 98 tons, then: the calculation method of steel bar loss rate = (100 98) 98 100% =.

The external dimensions of the steel bar skeleton are inaccurate, and the ends of multiple steel bars should be aligned when binding, so as to prevent a steel bar from deviating from the specified position and distorting the skeleton during binding.

The thickness of the protective layer mortar cushion block should be accurate, and the spacing of the cushion block should be appropriate, otherwise it will lead to cracks on the cantilever surface of the slab and exposed ribs on the side of the bottom column of the beam.

The loss rate of forming steel bar binding is 1, and the loss rate of material breaking in the production of forming steel bar has been included in the unit price of forming steel bar). The total loss rate of the steel bar in the steel concrete member should be, usually calculated as.

Cast-in-place concrete component reinforcement within 10 3%, 10 or more, grade steel 3%, pile foundation reinforcement cage.

2%, 3% reinforced in masonry, precast concrete member steel bar within 10, above 10, grade steel 3%, prestressed steel wire 9%, prestressed steel wire (steel strand.

6%, post-tensioned prestressed reinforcement.

13%, other prestressed steel bars 6%, iron parts 1%.

Calculation method of steel bar loss rate = (total amount of raw materials incoming total amount of material list) total amount of material list * 100%.

When the total amount of raw materials is 100 tons (the remaining is 0) and the total amount of material is 98 tons, then the calculation method of steel bar loss rate = (100 98) 98 100% =

Rebar refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including round steel bars, ribbed steel bars, and torsion steel bars. The steel bar for reinforced concrete refers to the straight bar or wire strip steel used for reinforced concrete reinforcement, and its shape is divided into two types: light round steel bar and deformed steel bar, and the delivery state is straight bar and disc round.

Wear rate, the probability that a child part will become a defective product in the process of manufacturing a parent part. The same child may have different loss rates when used to produce different parents, so it is defined in the BOM of the bill of materials. It refers to the production enterprise in the process of producing products, according to the normal defects and losses in the approved unit of product consumption and total consumption of the loss of a certain ratio of the spike rate.

The loss of construction engineering is generally 2-3%, beyond this is the management is not in place, the blanking circle macro elimination is not calculated, now the steel bar has electroslag pressure welding and straight thread even the return connection, the manufacturer can also provide 6 meters or 9 meters of fixed length, as long as the calculation in advance is good, the waste is very little.

The calculation method of the steel bar loss rate = (the total amount of raw materials and the total amount of material rent and loose orders) multiplies the total amount of the material list by 100%, for example, the total amount of raw materials is 100 tons (the remaining is 0), and the total amount of the material list is 98 tons, then: the calculation method of the steel bar loss rate = (100 98) 98 100% =. Among them, the subheading of steel bars and iron parts of the division has included the production and installation loss of steel bars and iron parts, and the loss shall not be calculated separately.

Are you asking about the quota, the quota is so stipulated (after 2000), the loss rate is 2%, is the comprehensive examination rate, this includes the residual value of the remaining steel bar to the top part, in fact, if you don't consider this problem, 2% is not enough, the common are about 4%.

We are in the construction of a project, we need to set a quota, according to the comprehensive unit price. All things considered, it can be between 3 and 5%.

Legal analysis: the attrition rate is 2%. The calculation method of the rebar loss rate = (the total amount of incoming raw materials, the total amount of the material list) divided by the total amount of the material list multiplied by 100%.

Legal basis: Construction Law of the People's Republic of China

Article 36 Safety production management of construction projects must adhere to safety first.

First, the principle of putting prevention first, establish and improve the responsibility system for safe production and the system of mass prevention and treatment.

Article 37 The design of construction projects shall conform to the construction safety regulations and technical specifications formulated in accordance with the provisions of the State to ensure the safety performance of the project.

Article 38 When preparing the construction organization design, the construction enterprise shall formulate corresponding safety technical measures according to the characteristics of the construction project; For highly specialized engineering projects, special safety construction organization designs shall be prepared and safety technical measures shall be taken.

Article 39 Construction enterprises shall take measures such as maintaining safety, preventing dangers, and preventing fires at the construction site; If conditions permit, the construction site shall be closed for management.

If the construction site may cause damage to adjacent buildings, structures and special working environments, the construction enterprise shall take safety protection measures.

Calculation method of steel bar loss rate = (total amount of raw materials incoming total amount of material list) total amount of material list * 100%.

When the total amount of raw materials is 100 tons (the remainder is 0) and the total amount of material list is 98 tons, then: the calculation method of steel bar loss rate = (100 98) 98 100% =

The probability that a child part will become a defective product in the process of manufacturing a certain parent part, and the same child part may have different loss rates when it is used to produce different parent parts, so it is defined in the BOM of the bill of materials.

The calculation method of the steel bar loss rate = (the total amount of raw materials and the total amount of the material list) The total amount of the material list is multiplied by 100%, and the production and installation loss of steel bars and iron parts have been included in the sub-headings of steel bars and iron parts, and the loss amount shall not be calculated separately.

We are in the construction of a project, we need to set a quota, according to the comprehensive unit price. All things considered, it can be between 3 and 5%.

3-5% with Party A

2-3% with on-site workers

It is stated in general contracts.

Check the calculation rules for the 2008 quota concrete chapter.

Calculation method of steel bar loss rate = (total amount of raw materials incoming total amount of material list) total amount of material list * 100%.For example, when the total amount of raw materials is 100 tons (the remaining is 0) and the total amount of material list is 98 tons, then: the calculation method of steel bar loss rate = (100 98) 98 100% =.

In the sub-headings of steel bars and iron parts, the production and installation losses of steel bars and iron parts have been included, and the loss shall not be calculated separately. The loss rate of various steel bars and iron parts is: 3% within 10 steel bars of cast-in-place concrete components, more than 10, and 3% of grade steel; 2% of pile foundation reinforcement cage; 3% reinforcement in masonry; Precast concrete member reinforcement within 10, 10 or more.

3% for grade steel; prestressed steel wire 9%; Prestressed steel wire bundle (steel strand) 6%; post-tensioned prestressed steel bar 13%; Other prestressed steel bars 6%; Iron parts 1%.

We are in the construction of a project, we need to set a quota, according to the comprehensive unit price. The screenshot is below.
