How to make house pillars not tilt, strong and durable

The problem of tilted poles.. Often caused by many reasons such as steel that is used to tie footings, piles, piers, no standards, not consulting specialists in construction directly, saving budget, choosing poor quality construction materials And many more, so we offer 5 techniques for tying piles and feet that anyone can do.

Note : We are a house building company. We have been a well-known company in the home building business for a long time. We have more than 5000 houses built in Thailand. find more information on our website :

1. Observe the overview of existing columns, beams or new bindings.

– For existing piles, beams, feet, can be observed with the naked eye immediately whether it is distorted or not. When I tried to notice, I didn’t see any difference. Another way is to use a “Plumb level” to achieve greater measurement accuracy.

– which the standard deviation of piles should not exceed 1 centimeter per column length 3-4 meters, if more The weight of the poles may be less than the limit, guaranteeing that it will definitely help reduce the problem of tilted poles.

2. Needle drilling, pile drilling

– If the pile drilling is wrong The resulting base will distort, causing the pillars to be skewed and tilted as well. Adjusting the three-legged piling tool to be in line with the center of the pile first Then use the basket to drill a deep hole (PRE – BORE) about 1.00 – 1.50 meters.

– Recommended for horizontal and vertical deviation is horizontal deviation 5 cm for single needle, horizontal deviation 7 cm for group needle, horizontal deviation 7 cm for group needle, etc.

3. Mixing process of concrete tying steel foundations, footings, piles

– Most often overlook or neglect the process of mixing mortar, concrete may cause cracks. Column leaks if used for a long time. Therefore, good and correct mixing of concrete. The ratio of cement, sand, stone should be 1: 2.5: 4, resulting in a concrete mix that has a strong, durable, tough, and excellent adhesion.

4. Choose high quality steel for tying the beam columns.

– Steel used for tying piles and footings should choose steel that has full steel standards. Strong, durable, for example, Black Annealing Wire. Standard diameter is 1.25 mm. Material quality is SWRM6K or SWRM6R. The amount of carbon (Carbon ) In the steel binding wire, there is only 0.12% manganese (Manganese) 0.4%, phosphorus and sulfur are absent in this steel.

– Steel binding wire must be flexible, strong, easy to bend (not hard to bend and not brittle and easy to break).

– Weight per coil (coil) 2.5-2.8 kg approximately, which is the appropriate weight. easy to move Size of the steel binding wire grid

5. Buying prefabricated piles, piers and feet

– Buying prefabricated pile feet will help in saving labor or for contractors who don’t have labor in hand, don’t have a team because tying pile footings on the foundation itself will take time and labor to tie. And sometimes the binding by hand may not be standard or the spacing of the steel is not equal. Can cause the house pillars to tilt as well

– Therefore, the purchase of finished pile feet is another option that can save time and budget for labor.
