1. Quantity calculation standard (not listed items refer to 04 quota Liaoning Province valuation table) a) Civil engineering, steel structure part.

Principles of calculation and valuation.

1. Concrete: calculated by volume according to the size shown in the figure. The volume occupied by the reinforcement and embedded parts in the component is not deducted.

2. Template: according to the area of the contact surface between the concrete and the template, calculated in square meters.

3. Rebar:

1) Different varieties and specifications should be distinguished, and calculated according to the length of the steel bar shown in the design diagram multiplied by the theoretical mass of the unit.

2) Number of reinforcement joints: the structure and structural lap case involve the calculation of the regulations or construction specifications; Lap of steel bar specifications, according to 10 25mm within every 8m of a joint; For every 6m joint other than 26, the lap length of the joint (including the hook) is calculated according to the current construction and acceptance specifications.

3) Electroslag pressure welding of steel bars, sleeve extrusion and other joints, calculated in pieces.

4) The engineering quantity of bolts and embedded iron parts shall be calculated by quality according to the size shown in the design drawing.

5) The supporting steel bars in the fixed position of the cast-in-situ components, the "iron horse" of the double-layer steel bars, the anchor steel bars of the outstretched components, the hooks of the prefabricated components, etc., should be incorporated into the reinforcement engineering quantity.

4. Earthwork and pile foundation engineering: large-scale projects can be tendered separately according to the market price

The calculation method is based on the different quantities of each project, and its calculation method is also different, basically according to the first subtraction of the main project, and then subtract some auxiliary projects.

1. Beam (1) frame beam 1. Calculation of the first span reinforcement 1. Upper through bar Upper through bar Upper through bar (upper through long bar 1) length = through span net span length + anchorage value of the head and tail end support 2, negative reinforcement of the end support Length of the negative reinforcement of the end support: ...

In addition to the amount of reinforcement engineering in a pump room, other engineering quantity calculation methods, because the pump room reinforcement project should have the provisions of the measurement department, the engineering plan worked out, its calculation method should be known through her design, and we have to find its calculation method through the network.

We will be happy to answer your questions, this engineering calculation is the length of the water pressure pump in the pump room and the water pipe in the pump room.

You can calculate other engineering quantity calculation methods other than the steel reinforcement project of a pump room according to his formula, and there is a special formula for other engineering quantity calculations, which can allow you to calculate an accurate number, so you can take a look. His formula.

If you want to calculate a way of engineering quantity, then you can directly find his formula in the browser.

Now in a certain pump room, in addition to the amount of reinforcement, there are still many other ways to calculate his engineering quantity, and it can still bring better use and help to all of us.

Generally, we use a ruler that we measure the house to measure whether the house is positive or oblique, and we measure it in this way.

I said that the girl can't measure the amount of other functions, and the quality of other functions is more than the calculated just before the pen calculates the energy.

If you want to do this company, you need a lot of stories to calculate, and you have to learn this story.

A certain pump room is played from the inside and outside of the steel engineering quantity, and other engineering quantity calculation methods, then it is possible to calculate his area.

If a certain water pump out other engineering calculations other than the amount of reinforcement, you will follow its prompts.

In other engineering quantity calculation methods, different types of work, its calculation methods and tools used in the calculation are different.

The centering span in the bearing is L, the width of the support is HC, the diameter of the main reinforcement in the support is D, the thickness of the protective layer is BHC, the anchorage length is LAE, and D is the diameter of the reinforcement.

1, the upper through rib 2 18

Single length = L + HC-2 * BHC-2*

Total length = single branch length * 2

2, the lower stress longitudinal bar 2 16

Single length = L + HC-2 * BHC-2*

Total length = single branch length * 2

3. Anti-torsion band N2 12

Single branch length = L-HC+2*15*D+

Total length = single branch length * 2

4. The total length of the left corner bar (only 1, the remaining 2 are through bars) = (L-HC) 3+

5. The right corner rib (there is only 1 in the first row, the remaining 2 are through ribs, and there are 2 in the second row) The length of the first row = (L-HC) 3+

Second row length = (l-hc) 4+

Total length = first row length + second row length * 2

6. Stirrups 8@100 200

Single branch length = (number of branches = (L-HC-2*1).

Total stirrup length = single length * number of threads.

Reinforcement summary: the total weight of reinforcement below 10 m (in kilograms) = the total length of all reinforcements (in m) * finally convert kilograms into tons, keeping 3 decimal places.

After the precast pile is set of quotas, you can directly enter the data, don't worry about other steel bars and concrete, the quota of the ** is included in these materials, after you summarize the calculation, enter the finished pile ** in the material line. If the software does not support this function, you can modify the material ** after setting the quota, but when you take the fee again, pay attention to delete the management fee and profit of this item, because it is already included in the previous **.

If the finished prefabricated pile is purchased, there is no need to calculate, and the market price of the pile material includes the production, transportation, loading and unloading costs of the pile

Reinforcement quantity calculation rules:

1. Reinforcement engineering should be distinguished from cast-in-situ and prefabricated components, different steel grades and specifications, respectively, according to the design length multiplied by the unit weight, calculated in tons.

2. When calculating the engineering quantity of reinforcement, if the design has specified the length of the reinforcement tower, it shall be calculated according to the specified tower length; If the design does not specify the length of the tower connection, it has been included in the loss rate of the reinforcement, and the length of the tower connection is not calculated. Joints such as electroslag pressure welding and sleeve extrusion of steel bars are calculated as units.

3. The pre-tensioned prestressed steel bar is calculated according to the external dimensions of the component, and the prestressed steel bar is pre-tensioned according to the reserved channel length of the prestressed steel bar specified in the design drawing, and different anchor types are calculated according to the following provisions

1) When screw anchors are used at both ends of low-alloy steel bars, the prestressed steel bars are reduced by the length of the reserved hole, and the screws are calculated separately.

2) When one end of the low-alloy steel bar adopts the head insert, and the other end of the screw anchor, the length of the prestressed steel bar is calculated according to the length of the reserved hole, and the screw is calculated separately.

3) When one end of the low-alloy steel bar adopts the emblem insert, and the other end adopts the gang anchor, the prestressed steel bar increases by 015m, the total increase of prestressed steel bars when the two ends of the gang anchor is calculated.

4) When the low-alloy steel bar adopts post-tensioned silicon self-anchoring, the length of the prestressed steel bar increases by 035m calculation.

5) When the length of the anchor channel is less than 20m for low-alloy steel bars or steel strands, the length of the prestressed steel bars increases by lm; When the length of the channel is more than 20m, the length of the prestressed steel bar is increased.

6) The carbon steel wire adopts a tapered anchor, and when the hole length is less than 20m, the length of the prestressed steel bar increases lm; When the length of the hole is more than 20m, the length of the prestressed steel bar increases by 1 8m

7) When the two ends of the carbon steel wire are upset, the length of the prestressed steel wire is increased by 035m calculation.
