In general, the wooden floor serves as a structure for building a Korat house รับสร้างบ้านโคราช or the contractor will know that the floor is placed directly on the joists to support the load. which will spread that weight to various wooden joists where the floor rests And it also serves to do during construction as well. When the floor and joists are assembled, in addition to supporting the load It also serves to help hold on to the resistance. or transfer the lateral force to the wall or pole to be a stable structure for the building
- Wood Floors Wood floors are popularly known as planks, plywood or other similar materials such as boards. that have physical properties that are strong enough to withstand the various types of force that the ground should have
- Overseas, the distance between the joists is stamped on the back of the plywood floor. However, in Thailand also in Ratchaburi province รับสร้างบ้านราชบุรี we can still use this distance between the joists. By looking at the comparison from the size of Tong on the left. where the first number is The distance between the joists is the largest for laying the roof. The last number is Maximum joist spacing for laying floors
- For areas with less thickness. 24″ (610) span lengths may also be used if the joist is used perpendicular to the joist, with a distance of 25⁄32″(20).visit here to know more information : world247zone
- Foundation material. It serves to reduce the impact of the load. And it is another layer of smoothing foundation before installing the surface material. This underlayment may be installed on the factory floor or can be installed later.
Floor slabs and underlayment
- The span lengths of the slabs shall be continuous in at least two or more intervals perpendicular to the joist.
- The seam will overlap the adjacent seam. for good coordination
- Leave a gap of approximately 1⁄8″ (3) and approximately 1⁄32″ (1) for the underlayment. according to the instructions of the manufacturer
- Use nails every 6″ (150) along the rim and every 12″ (305) between the center edges: Use a nail every 6″ (150) along the rim edge on both sides. and between the middle edge of the finished sheet type 2-4-1
- Use 6d or 8d nails for slabs up to ¾” (19) thick and 8d nails for slabs 7⁄8″ (22) thick and above.
- Place the joists at the edge of the panel subfloor. If the slab joint and the subfloor joint (underlayment) are in the same line.click here for more : kingnewsweb
In the event that the slab has a foundation material attached to it from the factory It may not be suitable if there are nail marks on the slab. (depending on the needs and type of floor finishing material) can attach the floor slab to the joist by using a special glue. This makes the slab and joist stick together as if homogeneous like a T-shaped beam, making the floor structure stronger. It may also be supplemented by shooting 6d nails with a power driven fastener.
Tongs and prefabricated trusses
At present, there has been an increasing number of wooden trusses or wooden joists. Instead of using sawn timber to support the floor system. Because the trusses or joists are lighter have a balanced cross-sectional shape and can be modified according to the strength that supports These trusses or joists are produced and sold abroad. However, in Thailand, they are custom-built for use in specific sizes.
- I-shaped thong made of plywood for waist. and as a lumber for the upper and lower wings
- Regular sizes 10″ to 16″ (255 to 406)
- Ability to lean over a long length:
- Depth 10″ (255), can be draped over 16′ (4.875) long.
- Depth 12″ (305), can be draped 19′ (5,790) long.
- 14″ (355) depth, can be draped over 22′ (6,705) long.
- Depth 16″ (405), can be draped over 25′ (7,620) long.
- Depth 12″ to 24″ (305 to 610)
- For general use, it spans 20′ to 60′ (6 to 18 m).
- A wooden truss structure with 2″ × 4″ main top-bottom parts, fixed to the serrated parts with steel couplings.
- Depth 12″ to 24″ (305 to 610)
- Can span 40′ to 60′ (12 to 18 m) long.
- Wooden trusses with diagonal support pieces.

- Can be draped over 40′ to 80′ (12 to 24 m) long.
- Truss with 2″ × 6″ double timber upper and lower parts with 2″ diameter steel pipe (51).
- Depth up to 60″ (1,525)
- Can be draped over 60′ to 100′ (18 to 30 m) long.
- The truss depth estimation is equal to the span length of 18.
- System works, such as conduits, can walk through the gaps of the trusses.
- Always check with the manufacturer (if applicable) for the correct information.Visit here : kingnews33
