Entry into the foundation The home builder company รับสร้างบ้านราชบุรี will need to study what kind of building structure is. How is the design? The wooden joists, wooden beams and trusses are important as follows:
Equipment for fixing walls and floors to the building should be provided at the top of the foundation wall.
• Steel anchors the floor and wall to the foundation wall. To prevent side pressure such as wind or vibration from earthquakes.
• Secure floors and wall bases with ∅ ½” (13) screw anchors, buried at least 7″ (180) deep in concrete, grout or brick, at a distance of not more than 6′ (1,830) or at least. Two bolts must be no more than 12″ (305) from either end of the edge. In seismic zones 3 and 4, more requirements or reinforcement are required.
• wooden frame wall
• Wooden head-tong
• Floor plank
• 2″ × 6″ or 2″ × 8″ leveling boards are placed on the sealant. to prevent air ingress
• May be wall paneled with bricks showing the style.
• Foundation walls may be entangled from the soil surface. to act as a wall on the side of the building as well
• Place the beams so that the roof level is ½” (13) lower than the back of the wall and the distance around the head of the beams is ½” (13) from the wall as well.
• The tongue is carved for the wooden beam.
• Wooden beams or joists.
• Padding material under the wood to prevent shock.
• Wedge to adjust the level of the joist.
• Shoulder width less than or equal to 3″ (75).
• Adjust the width of the shoulder.
Sheer waist trusses and home building รับสร้างบ้านโคราช work are things that need to be taken into account. The details of sheer waist trusses are as follows
• Connect the sheer waist truss to the steel plate embedded in the wall of the brick wall base.
• The foundation wall which raises and serves as the wall of the external side wall of the aboveground building.
• Sheer ribbed ribbed bottom.
• The truss receiving area is at least 4″ – 6″ (100 – 150) and at least 6″ – 9″(150-230) for long span trusses.
Typically, when a wall is built lower in the soil surface, such as a foundation, this wall also functions as a basement. which may affect the surrounding environment, therefore a rise protection system or basement wall is necessary. If the wall is deeper than the groundwater or groundwater passages, water may seep in. Regulations may also require such protection systems to be included in certain types of buildings.
• Waterproofing sheet should run continuously beyond the soil surface 6″ (150).
• Waterproofing membranes may be made of bitumen or acrylic material. Use with cement to plaster the surface.
• For masonry walls should be plastered with a thickness of not less than 3⁄8″ (10) and topcoat with 1⁄16″ bitumen waterproofing material (2).
• Waterproofing membranes may be made of polymer rubber mixed with bitumen. or other materials that have been tested
• bentonite clay May be used to spray directly on the wall. or in combination with wavy card board which bentonite will swell when exposed to water and will prevent water from flowing through
• Prevent the surface of the waterproof material from being impacted and falling off. while covering the soil by inserting a drainage plate or solid foam packing sheet or a protective sheet made of asphalt
• Gap sealant that can be stretched and contracted in expansion joints.
• waterproofing strips
• Concrete slab at least 4″ (100) thick.
• Waterproofing sheet if necessary.
• Cardboard or Protection Board or Fiber filled with bitumen or foam.
• Rough concrete layer is intended for coating cases. Surface of the floor with waterproofing sheet
Underground drainage is important. Groundwater drainage is the diversion of groundwater from a foundation into a public drainage system or a well below it.
• Drainage plate or gravel filling. to drain water into the drain pipe below.
• Approximately ¾” (19) thickness drainage plate made of synthetic material. or a sieve with a cloth face that acts as a filter that allows water to easily pass through. but will not allow soil particles to pass through
• Scrape the corners with cement-sand or non-degradable material.
• Paving with gravel or small stones at least 6″ (150) thick.
• Protect the surface behind the drain with a filter cloth.
• A ∅ 4″ (100) pipe with perforations all around.
• The bottom of the pipe should be lower than the floor level. and should have a slope to drain water to public pipes
• At least 2″ (51)
Foundation wall system made of lacquered wood Can be used to build a base and a channel under the floor of the building. or under the basement Walls can be prefabricated or assembled on site. The wood used for construction must be improved. and coated with a specific solution to prevent wood decay or decay because the wood is buried underground
• At least 5% slope
• Polyethylene waterproofing sheet 6″ (150) spacing together with waterproof material.
• Cover with gravel or rock for drainage.
• Drainage pipes around the wall.
• The foundation is made up of timber, gravel, sand or rock, at least 4″ (100) thick.
• The lower truss beam has a width of D depending on the weight applied to the wall. and the ability to withstand soil loads
• Sump with gravel, sand or rock to drain water out. and let the sedimentary soil have a width of ∅20″ (510) or 24″ (610) in a square shape and a depth of 24″ (610) from the concrete bottom.
• The trim is at least 2″ (51) off the floor and has a 5″ (125) sinking section to protect the polyethylene from ultraviolet rays and shock.
• Wood fixing the wall frame on the top piece. Used to hold sections of walls together. The joints between the pieces of the top placement should not coincide with the joints of the bottom pieces.
• The truss holder on the lower frame is hammered down roughly by nails.
• Improved waterproof plywood at least ½/” (13) thickness.
• Joints size 1/8″ (3) are sealed with waterproof material.
• 2x wooden brackets for the lower wall frame, the upper piece. 12″ or 16″ spacing (305 or 405)
• Reinforced with insulation. moisture proof sheet and decorative materials as required
• 2x brackets for the lower wall bracket bottom
• 1x Apron
• wooden wall
• Two lower trusses raised above the floor.
• Gravel or sedimentary rock is placed continuously in the area where the ground will be constructed for drainage.
