The calculation formula of reinforcement engineering quantity: reinforcement engineering quantity = reinforcement length wheel ant (m) weight of reinforcement per meter (can check the theoretical weight table of reinforcement) (kg m).

Rebar refers to steel for reinforced concrete and prestressed reinforced concrete, which has a circular cross-section and sometimes a 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.

The light round steel bar is actually closed, and Tong Bang is a small round steel and a disc round of ordinary low carbon steel. Deformed steel bars are ribbed steel bars with a surface, usually with 2 longitudinal ribs and transverse ribs evenly spaced along the length. There are three types of transverse ribs: spiral, herringbone, and crescent.

It is expressed in millimeters of nominal diameter. The nominal diameter of the deformed steel bar is equivalent to the nominal diameter of the light round steel bar with the same cross-sectional car row surface.

Steel bars are mainly subjected to tensile stresses in concrete. Due to the action of ribs, the deformed steel bar has a greater bonding capacity with concrete, so it can better withstand the action of external force. Steel bars are widely used in various building structures. Especially large, heavy, lightweight, thin-walled and high-rise building structures.

Summary. 1. Calculating the engineering quantity of reinforcement needs to combine different steel grades and different specifications, and then multiply the weight of the unit according to the designed length, and finally you can get what the engineering quantity of reinforcement is. It is calculated in tons, and when calculating the amount of reinforcement, because the reinforcement has been lapped, the lap length will be generated, and then it will be calculated according to the specified lap length.

However, if the design does not specify the lap length, it will be included in the loss rate of the reinforcement and the lap length will not be calculated separately. 2. However, for different types of reinforcement, there is no certain difference in the calculation method. For example, there is a low-alloy steel bar, and its two ends should be screw anchors, so the calculation will be based on the reserved hole length and then subtract meters, and the screw needs to be calculated separately.

For example, there is a kind of low-alloy steel bar, and its two ends should be screw anchors, so the calculation will be based on the reserved hole length and then subtract meters, and the screw needs to be calculated separately.

3. If it is a low-alloy steel bar or steel strand, it is necessary to control the length of the anchor channel within 20 meters, and the long beam of the steel bar that corresponds to the delay needs to be increased by 1 meter. If the length of the aperture reaches more than 20 meters, the length needs to be increased by meters.

This one. Calculation formula: steel bar engineering quantity = steel bar cutting length (m) corresponding steel bar weight per meter (kg m).

Summary. Calculation formula of reinforcement: general length of straight reinforcement = length of component - thickness of protective layer at both ends + hook + other added value; The length of the bending rib = the length of the component - the thickness of the protective layer at both ends + the hook + the increase of the oblique length + the added value of other added value; Closed limb hoops = (b+h)*2-8(c-d)+2*; Stretch = b-2 * (c-d) +;

Reinforced concrete is treated with waste heat to treat steel bars: water is penetrated immediately after hot rolling, surface control cooling is carried out, and then the finished steel bar obtained by tempering treatment is completed by using the waste heat of the core.

What is the rebar takeoff formula?

The formula for the calculation of reinforcement is wide and clear: general straight bar length = component length - thickness of protective layer at both ends + hook + other added value; The length of the bending rib = the length of the component - the thickness of the protective layer at both ends + the hook + the increase of the oblique length + the added value of other added value; Closed limb hoops = (b+h)*2-8(c-d)+2*; Stretch = b-2 * (c-d) +; Reinforced concrete is treated with waste heat steel waste heat treatment steel positive bending ribs:

Immediately after hot rolling, water is penetrated, surface controlled cooling is carried out, and then the waste heat of the core is used to complete the finished steel bar obtained by careful vertical tempering treatment.

Ribbed reinforcement: The surface is usually rotten with two longitudinal ribs and evenly distributed along the length of the rib bar. Crescent rib reinforcement:

The longitudinal section of the transverse rib is crescent-shaped and does not intersect with the longitudinal rib. Longitudinal rib: A uniform continuous rib parallel to the seepage line of the rebar shaft.

Transverse ribs: Other ribs that are not parallel to the longitudinal ribs.

In the construction industry, steel bars are one of the common building materials. In the process of building design and construction, it is important to accurately calculate the amount of reinforcement used. Here are the steps on how to calculate the amount of reinforcement.

Step 1: Define the size and number of canopy components.

Before determining the amount of reinforcement, it is necessary to clarify the size and number of components. The length, width, and height of the components are best calculated by an engineer according to the design requirements. The quantities must also be accurate.

Step 2: Calculate the number of reinforcements required for each member.

Depending on the size and number of components, the number of reinforcements required for each component can be calculated. The length of the reinforcement is equal to the perimeter of the member plus a portion of the margin. Typically, the margin is 50 100 mm.

Then, the number of bars required for each member is calculated based on the rebar diameter, rebar spacing, and number of bars set within the member.

Step 3: Calculate the total amount of reinforcement.

After calculating the number of reinforcements required for each member, they need to be added together to get the total reinforcement amount. The total weight of each type of bar can be multiplied by the number of bars and then added to get the total amount of bars. In practice, it is necessary to take into account the actual conditions of the project in the total calculation process, such as the need to retain additional backup bars and longitudinally stressed reinforcement.

Step 4: Adopt a legal calculation formula.

When calculating the amount of reinforcement, a legal calculation formula must be used, such as JGJ 08-2004 "Code for Quality Inspection of Reinforcement and Prestressed Concrete Engineering in Construction Engineering" or GB 50010-2010 "Code for Design of Concrete Structures". These specifications provide clear calculation methods and formulas, ensuring that all necessary factors are taken into account in the calculation process.

Step 5: The steel bars should be firmly dusted and carefully connected.

A strong connection of the rebar is very important to ensure the strength and stability of the member. When the construction design and construction are completed, the rebar is connected using a qualified welder or rebar connector. In this process, it is essential to keep in mind the lap length of all connections to ensure seamlessness.

Inspection and acceptance are carried out according to the requirements of the project supervision and inspectors.

Step 6: Other factors to consider.

There are other factors that need to be taken into account in the calculation of the amount of reinforcement. For example, the diameter, brand, and quality of the rebar. Measure the accuracy of the measurement and other measurement data. In addition, during the transportation and storage of steel bars, the integrity and quality of steel raw materials are ensured.

The above is how to calculate the amount of reinforcement, which needs to be accurate and cautious at all times to ensure the safety and stability of the project.

Summary. The detailed calculation process of the reinforcement calculation.

Dear, I'll take a look at the situation, so please wait a moment

Hello, there is only a cross-sectional view, which cannot be calculated. Explain what you need.

Can't solve it.

What documents do you need, I'll send it to you.

The cross-section view does not calculate the exact usage.

How can it not be counted.

A cross-sectional view that only shows the use of reinforcement, and there is no specific amount of reinforcement.

The reinforcement above the well is the reinforcement diagram, and the one below is the section drawing, and the amount of reinforcement in the well chamber and the floor is calculated, and how much reinforcement is used.

A cross-sectional view showing the specific practice and location of the beams and columns.

What needs to be understood is the number of specific beams, the specific situation of the bottom plate, and the requirements of the reinforcing ribs of each link, etc., which can not be explained in one or two pictures. Calculating the reinforcement requires a drawing of the whole unit, which is a time case that needs to be calculated a little bit.

The beam body is reinforced with 16 20 steel stirrups and there is no specific size for the size and usage.

These are all cross-sectional drawings that require each part, a plan showing length data, and a reinforcing bar of the reinforcement joints.

Reinforcement takeoff is a very important part of building design, which involves the stability and load-bearing capacity of the building structure. The reinforcement calculation is to calculate the number of reinforcement required for the building according to the design drawings, so as to formulate a reasonable procurement plan and construction plan.

First of all, the reinforcement takeoff needs to understand the relevant data in the design drawings, such as the size, shape and number of reinforcement required for components such as walls, columns, beams, etc. Depending on the specific design requirements and the load-bearing capacity of the building, the diameter and spacing of the reinforcement required for each component can be determined.

Secondly, the reinforcement takeoff needs to calculate the total length of the reinforcement for each member, which can be obtained by multiplying the length and width of each member. Based on the diameter and spacing of the rebar required by the member, the length of each bar can be calculated, and the number of bars required for each member can be derived.

Finally, the number of reinforcing bars required for each component needs to be added together to get the total amount of reinforcing bars required for the building. According to the specifications of the steel bar and the market, you can calculate the budget of the steel bar required for the construction and formulate a reasonable procurement plan.

In summary, the calculation of reinforcement has an important impact on the quality of architectural design and construction progress. Architects should carefully implement reinforcement calculations to ensure that buildings meet design requirements, while also saving costs and improving efficiency.
