WHAT IS THE APPLICATION? LEARN ABOUT STRUCTURE AND HOW TO DESIGN NAIL

The house is made up of nails, so do you know what a single nail (the simplest nail type) is? Or have you ever been curious about the structure of a single nail, and how it is designed? If you have questions about these issues, please read the following article of MOIVAONHATOI to understand clearly what single nail is.

WHAT IS NAIL?

Single nails have another name, cup nails, which support one or a cluster of columns. Commonly used for buildings under 3 floors. Single foundations are located at the base of the column, which can be hard, individual or soft nails and often reinforced with cajeput.

WHAT IS THE STRUCTURE OF NAIL?

The structure of a single foundation is very simple, made up of a thick reinforced concrete and formed a single cylinder. For industrial projects, people take advantage of the foundation bottom placed on a good layer of soil with a depth of about 1m. This helps to create a level surface to avoid switching between areas bordering on good and bad soil. Avoid expansion of soils due to saturation with water.

In construction, the foundation is linked to one or more beams. Works against the wall system built above. There is also the effect of bracing the cup foundations to avoid settlement and deviation between the foundation stations.

WHAT IS SUSTAINABLE STEEL STRUCTURE?

Single-nailed steel will be of the highest quality steel. Single foundation reinforcement can be machined in the field or in factories. But to comply with technical drawings specifications. Clean all site surfaces, assemble according to the design drawings.

In welding - welding, it is necessary to ensure firm joints. Avoid the heat to burn the formwork. The rebar must be ensured free of mud, grease, and rust. If the case of iron bars are flattened or cut, the cross-section should not exceed 2%.

The welds must ensure> 10d

Forced concatenation> 30d

The solder joint needs to be cleaned

Steel ends should be protected with plastic bags.

COCONUT NAIL SALON

To construct a solid single-sheet foundation, it is necessary to treat a sturdy foundation first. Using melaleuca poles for reinforcement is a measure used a lot in construction. because of its convenience and relatively cheap price compared to other synthetic materials. Cup foundation is an intermediate load unit. Transfer weight from the building to the ground layer. And this ground layer is reinforced with melaleuca piles. There have been hundreds of projects in Ho Chi Minh City using Melaleuca foundations that are still standing and have a high safety rating.

WHAT IS THE DESIGN OF THE NAIL?

Depending on the construction works, contractors will choose to calculate and execute for each type. Same way of calculating but will divide each detail for the project. The single foundation under the column is made of gravel, this part is calculated according to the strength of the foundation building material. Cup foundations (single) under the wall are placed 3 to 6 meters apart along the wall and placed under the corner walls. At load-bearing walls and at places where loads are concentrated on the foundations.

Many designs will have different advantages and disadvantages, many plans will arise. Depending on that, engineers will design more details.

TAM TAM NAIL DESIGN

The cause of the eccentricity is that the problem posed is the balance of the foundation block. Engineers can create this balance in the following ways:

• Ground jets possess a triangular or trapezoid form. Then the center of this jet system will move compared with the center of the radio. The base station balance will be established when the center of gravity of this jet system coincides with the setpoint of the force system transmitted down from the column. This approach is often less efficient or unusable in the case of a large eccentric torque. Then the jet is usually triangular, to balance as above, the maximum mobilized foundation width is only 3/2 column width. If the longitudinal force is large, it cannot be superficial to satisfy ground pressure conditions.
• You can use a human toenail or a propeller to reduce eccentricity. In addition, there are many opinions that it is necessary to add anti-roll columns, but calculations think that the presser foot style is correct.

NAIL DESIGN STANDARDS

• The selection of construction methods, construction of coke foundations - single must consider geological survey data. Additional calculation must be carried out if the actual engineering geology of the construction site is inconsistent with the calculations in the single foundation design.
• All materials, supporting machinery and structural parts used in the construction of cup foundations (single) must satisfy the design requirements.
• When building single foundations, it is necessary to have the technical inspection of the agency.

COMPUTER NAIL DESIGN

If the ground deformation is not too large, we apply elastic theory to calculate strain properties. Take advantage of the background working ability in the stage of linear deformation. Formula for calculating single foundation in accordance with technical process:

When the load is right to center of gravity: P ≤ R

When the eccentric load: P ≤ 1.2 R (P, P: average and maximum foundation pressure; R: standard strength of the ground)

R = m (A .γ.b + B.q + Dc) (3)

Inside

b: Width of foundation base

q: Side load of foundation

c: Unit cohesion of the ground layer

A, B, D: The coefficients depend on the angle of the internal friction of the soil.

m: Coefficient of working condition of single foundation

CONSTRUCTION SINGLE DESIGN

Understand what single foundation is, as well as the structure of the foundation, so what should we pay attention to when constructing the single foundation design? MOIVAONHATOI would briefly list as follows:

• Site preparation: Before construction, site preparation, labor, machinery, raw materials, ... are required.
• Leveling: Conducting leveling for the foundation construction process
• Preparation, reinforcement work: Steel selected and correctly machined with all criteria

Above are some basic knowledge to help you understand what a single nail is, as well as its structure and design. Hope this information has helped you clear your questions, and maybe you will need to use them during construction. upgrade house.
