Column embedding distance

The length of the column embedding has different slopes. house building company รับสร้างบ้านราชบุรี Always study the slope distance every time with the following details:

Column embedding distance for areas with high slopes

  • 5 to 8′ (1,525 to 2,440) for poles on the ground which, although shorter than poles below the mound, But it needs a deep hole to provide high strength and help hold the entire structure.
  • 4′ to 7′ (1.220 to 1,525) for the columns below the hill.

Column embedding distance for low slope areas

  • 4′ to 7′ (1,220 to 1,525)

In the case of steep slopes, there are conditions that do not allow the pillars to be buried in the soil, such as rocky foothills. We can use diagonal steel bars with accelerator threads. or a wall that receives fuzzy forces instead in order for the building structure to be stable against lateral forces

A structural engineer should be consulted when designing and constructing this type of foundation on an area with steep slopes, wind loads, or flooding.

The split double beams or joists are threaded through knots through the posts to the other side. To assemble a frame to support the weight of the building above.

  • The beam is attached to the column by notching the column. to increase the area to support the load from the beam
  • Seal holes and cuts with wood protection material from moths or insects.
  • Spiked Grid fasteners are secured with one bolt. Will bear the weight better than the notched pole joints.
  • Wood/Steel
  • Double beams articulated together.
  • A stanchion that stops at the ground is attached to the beam. by using wooden or steel plates

The poles and bases normally transfer forces into the soil below, but pouring concrete collars will increase the distribution of the force. and most importantly, it helps to support the pillar to prevent it from tilting due to the weakening of the backfilled soil.

  • Solid wood columns
  • floor level
  • Anti-rust-plated steel anchor at the base of the column is poured into the concrete base.
  • The concrete base transfers the weight from the column to the soil. The size of the base should be designed by a structural engineer.
  • Pour the concrete backing.
  • Dowel pins anchored to concrete.
  • Fill back with coarse sand, gravel or crushed stone.
  • The groundwater level has turned to ice.
  • Filling back with pure concrete or cement-soil mixture. It will increase the strength to prevent the column from tilting. Suitable for cases where the floor has a high slope. The condition of the reclamation soil was weak. or want the pole to be buried shallower than specified

Deep foundations when building a house  รับสร้างบ้านโคราช  must study this matter carefully. The details of deep foundations are as follows:

Deep roots penetrate through soil layers that are weak or not yet strong enough to support heavy loads, such as large buildings that rely on long piles to transfer weight from the building to the deeper layers of solid soil. There are two types of deep foundations: pile foundations and caesong or chimney foundations.

Deep pile foundation It is a system of supporting the weight transferred onto the pile by back pressure at the tip of the pile located on the soil layer of the subsoil. or back pressure on the pile surface Due to the friction between the pile surface and the soil surrounding the pile, the position of the foundation determines the length of the beam.

  • load-bearing walls
  • Pin headers and foundation beams
  • Group Hammer Distance between pin centers 2′ 6″ to 4’0″ (760 to 1,220)
  • Reinforced concrete head cover. will hold the needle from moving and serves to distribute the weight from the pole to the pile at the same time
  • Size changes according to the weight of the pole at least 12″ (305).
  • Placed below the groundwater level changes to icy state.
  • Piles may be piles made of wood. But for large buildings, prestressed concrete columns are often used or with prestressed reinforcement, hollow piles or H-shaped piles.
  • The piles are hammered by a crane. which is made up of a high standing steel frame There is an engine for raising the pile into position before lifting the pendulum to drive the pile into the ground. The crane will move along the steel track.
  • Foundation piles are mainly loaded with resistance at the tip of the pile. By allowing the soil around the piles to be just a thing to support the sides to resist the buckling force in the case of the piles being very long
  • Short piles mainly use the friction between the pile and the soil around the resistance pile. There will be a friction value depending on the type of soil surrounding the pile.
  • The permissible weight for each pole is is the maximum Both axial and horizontal used in pile design are determined from static load testing or from soil exploration drilling.
  • In case of misalignment or deviation of the pile from the designed point or the pile is tilted, it will reduce the load bearing capacity of the pile, hard soil (shale) or rock.
