How to calculate the elevation of the top of the foundation beam? How to calculate the elevation of

These all depend on the drawings,1

How much can you get to the cap under the foundation beam.

Elevation, generally the foundation beam is built on the cushion cap, and the elevation of the foundation beam minus the beam height is the elevation of the cushion cap.

2. The foundation can be dug deep to the cushion.

Elevation. Underneath the foundation is the cushion, you can see how high the foundation is on the drawing.

3. If there is a pile foundation, how deep should the leveling earthwork go down to reach the cushion elevation, pile foundation.

Where does the cushion come from, the general pile foundation is the cushion cap, and then the foundation beam.

4. How to calculate the cushion elevation.

If it is the cushion of the foundation, it is the top elevation of the foundation minus the height of the foundation is the top elevation of the cushion, and the thickness of the general cushion is 100.

The function of the ground beam (not for the strip foundation under the column): 1. The column base is connected with the tie (similar to the floor beam); 2. Lift a layer of wall to prevent the wall from settling.

Therefore, the principle of determining the elevation of the ground beam: 1. Indoor plus or minus zero below 200mm (leaving the indoor floor practice); 2. Set aside space for indoor underground pipelines (water, electricity, gas, etc.).

If the height difference between indoor and outdoor is relatively small, within 300mm, you can take the position of plus or minus 0 and a brick, for example, you can.

If the height difference between indoor and outdoor is relatively large, such as 550, 600, etc., and the beam height is relatively small, such as only 400, it is recommended that the beam elevation is done, and the principle is that when the backfill is made, the peripheral beam should be able to wrap the backfill.

Beam top elevation (indicates that the top surface of the beam is lower than the floor of the structural layer in which it is located.)

1. When there are no special requirements for Qingqin's general project, the foundation beam.

The top elevation is taken as flat as the top of the foundation short column).

2. The structure of the foundation beam is noted in the drawings: the plain soil is compacted first, and then the slag is 300 thick, and the bottom of the beam is left with a high void of 100.

3. The plane positioning size of the foundation beam must be clear, and if the foundation beam support does not completely fall on the foundation short column, that is, when the end of the foundation beam is suspended or partially suspended, it should be indicated that the beam is filled with the same number and pouring plain concrete, and the foundation short column is strictly forbidden to appear convex.

4. The foundation beam is generally poured with C20 or C25 grade concrete.

5. Note that the elevation of the foundation beam is generally taken as 1 12 spans. When the span is 6m, the beam height is generally 500; When the span is last, the beam height is generally 600 or 650; The size of the beam reinforcement should be determined according to the load calculation based on the delay argument, which can generally be taken 6 16, 8@100 200.

When the foundation is calculated according to the axial force, when the superstructure comes to the bottom code and the bending distance is balanced by the foundation beam, the foundation beam should be arranged on the top surface of the foundation, and when the foundation beam only plays the role of connection or as the first layer of wall foundation, can be arranged at the elevation.

The calculation formula of the elevation at the bottom of the beam is the elevation at the bottom of the beam = the elevation at the top of the beam - the elevation at the top of the beam - the elevation at the top of the slab (the elevation at the top of the beam) indicates the height of each part of the building, which is divided into absolute elevation and relative elevation, and the elevation is the corresponding height of each part of the building.

The standard of elevation is determined according to the thickness of the surface layer in the building floor practice. The elevation is of great significance in navigation, such as the airport elevation will be directly related to the take-off and landing performance, maneuverability and flight weight calculation of the aircraft; For example, if you do not know the target marking, you will not be able to complete professional flight tasks such as surveying, airdropping, prospecting, agriculture and forestry.

The elevation of the top of the beam is generally the floor of the structure, and the elevation of the structure is the elevation of the building minus the decorative layer of the floor. Therefore, the elevation of the top of the beam is generally the elevation of the building Zheng Zhizhu floor minus.

Synthesizing the three aspects of the question you raised, I will explain the meaning of each noun as follows:

1.The elevation of the top of the beam is the relative elevation of the top of the beam of this layer, which is generally consistent with the elevation of the top of the plate and the structure of the layer!

2.The datum elevation of the top of the beam is the distinction between the relative elevation and the absolute elevation of the beam, and only when distinguishing between the two can there be this concept, such as the top of the first floor, which is the datum elevation.

3.The floor elevation is the structural elevation required by the floor to meet the requirements of the building, which is generally consistent with the elevation of the top of the beam and the elevation of the top of the slab.

Summary. Hello, the elevation of the top surface of the foundation is equal to the elevation of the top surface of the strip foundation or cushion cap, and the elevation of the ground beam or foundation beam can be flat with the top elevation of the foundation, or it can be higher than the top surface of the foundation.

Hello, the elevation of the top surface of the foundation is equal to the elevation of the top surface of the bearing platform of the base or the town reformer, and the elevation of the ground beam or the foundation beam can be flat with the elevation of the foundation top annihilation, or it can be higher than the top surface of the foundation.

Generally, the height of the ground beam is still the height of the bearing platform, and what does it mean that the ground beam is negative.

Teacher, the elevation of my building is, and then the rear view elevation is, the rear view reading is quietly rotten, the ground Qishan beams are 250 * 650, the drawings h=, how much is the excavation depth of the ground beam.

The ground beam is high. The roof of the beam is higher than the building elevation of this floor.

How to calculate the excavation elevation.

The base elevation and foundation height are marked on the drawings and do not need to be counted at all.

What should be the depth of excavation?

Is it going from plus or minus zero?

Right. Ok thanks.

Summary. Hello, the elevation of the top of the beam is generally the floor elevation of the structure, and the structural elevation is generally the elevation of the building minus the decorative layer of the floor. Therefore, the elevation of the top of the beam is generally the elevation of the building floor minus.

Hello. Hello, the elevation of the top of the beam is generally the floor elevation of the structure, and the elevation of the structure is generally the elevation of the building minus the decorative layer of the floor floor.

700 beams, beam top elevation meters How to calculate this beam.

The elevation of the foundation beam is generally taken as 1 12 spans. When the span is 6m, the height of the empty Lashen beam is generally 500; The span is time, and the beam height is generally 600 or 650; The size of the beam reinforcement should be determined according to the load calculation of the local slag, which can generally be taken 6 16, 8@100 200.

Five meters of floor height, 700 beams, you don't care about the thickness of the ash when you put the beam, first copy a one-meter level, or one meter five, two meters, set by yourself! For example, the level of one meter of Pai Peixiao, the level of 5 meters minus 1 meter, and the beam of 700 are equal to meters. Reduce the height of the bottom of the beam, and some of the bottom of the beam are equipped with flat square wood, which is five centimeters.

With vertical square wood, it is 9 centimeters of dust, and it can also be calculated according to 10 centimeters, and then reduce the steel pipe, some construction site companies are not allowed to directly put the bottom pipe of the beam, and you want to add a crossbar. If you add a crossbar, you have to subtract another 5 cm. If you don't add it, just subtract the thickness of the bottom of the beam!

The upper crossbar is equal to, 5-1=, which is the height of the steel pipe at the bottom of the beam from the level of one meter!

700 beams, beam top elevation meters How to calculate this beam, I ask you how much the height of this beam is tied.

700 beams, beam top elevation meters, beam tied height matching.

Is it the total elevation of the 1-meter line to add the beam tie?

Yes. I don't understand what it means to have a negative elevation at the top of the beam.

That is, the elevation of the top of the beam is higher than the elevation of the top of the floor.

H is the elevation of the floor of this floor, and H+ means that the elevation of the top of the beam is higher than the elevation of the floor of this floor.

Beam top elevation (indicates that the roof of the beam is lower than the floor of the structure of the god servant Hui where it is located.)

Is it the total floor height of the structural layer minus 5 cm.

It is usually considered by 5 cm, but sometimes there are waterproof requirements in the place is not, such as the bathroom, kitchen, roof, basement roof, basement floor, etc.
