1) elastic line punching:
The width line and center line of the partition wall will pop up on the ground and building wall where the wooden partition wall needs to be fixed. At the same time, draw the position of the fixed point. Usually at intervals of 300-400mm, drill holes on the center line with a 7.8mm or φ 10.8mm drill bit, with a depth of about 45 mm, and insert M6 or M8 expansion bolts into the holes. Pay attention to the position of the hole should be staggered with the vertical wood square of the skeleton. If it is fixed with a wooden wedge nail, it is necessary to make a hole with a diameter of about 20 and a hole depth of about 50mm, and then drive a wooden wedge into the hole.
2) Fixed wooden skeleton:
There are several ways to fix wooden skeleton, but in interior decoration engineering, the principle of not destroying the original building structure is usually followed to deal with the skeleton fixing work. Fixed wooden skeletons are usually located along the wall, along the ground and along the top surface. Before fixing the wooden skeleton, draw a line on the wooden skeleton according to the position of the fixed point on the ground corresponding to the top surface of the wall, and mark the position of the fixed point. If fixed with expansion bolts, holes should be punched at the marked fixing points. The diameter of the hole is slightly larger than that of the expansion bolt.
For the half-height partition wall, it is mainly fixed by the ground and the building wall at the end. If the end of the short partition wall cannot be fixed with the wall, the end is often reinforced with iron pieces.
For all kinds of vertical wooden squares of wooden partition walls, the method of iron reinforcement is adopted, otherwise the wooden partition wall will have a great vibration due to the opening and closing vibration of the door, which will make the door frame loose and the wooden partition wall loose.
3) Connection between partition wall and ceiling:
For example, the top of the partition wall is not a building structure, but is in contact with the ceiling, and its treatment method depends on different ceiling structures.
For partition walls without doors, when contacting with aluminum alloy keel ceiling or light steel keel ceiling, only small and straight gaps are required. When in contact with the wooden keel ceiling, the wooden keel of the ceiling should be nailed to the top keel of the partition wall. If there is a seam between the two, it should be padded before nailing.
For partition walls with doors, the top should also be fixed considering the vibration of the opening and closing doors and the collision of people coming and going. The fixing method is as follows: the vertical keel of the wooden partition should pass through the ceiling surface, at least the top of the vertical keel of the door frame should pass through the ceiling surface, and then be fixed with the top surface of the building floor above the ceiling surface. Inclined brace is a common fixing method. The diagonal brace can be wood square or angle iron, and the included angle between the diagonal brace and the top surface of the building floor is 60 degrees. The inclined support and the top surface of the building floor can be fixed with wooden wedge nails or expansion bolts.
4) Wood plywood for fixing wood partition:
There are two main ways to fix the wooden splint on the partition wall: open seam fixing and flat-fell seam fixing. Open seam fixing refers to leaving a seam with a certain width between two plates. If there is no provision in the construction drawing, the joint width should be 8-10 mm. If there is no pad at the open joint, the surface of the wooden keel should be planed, and the width of the open joint should be the same from top to bottom. When sawing wood plywood, the straightness and dimensional accuracy of the kerf should be guaranteed by the guide rule, and the edge should be trimmed with #0 wood sandpaper. When flat-fell seam is fixed, the four sides of the front of the wood plywood should be chamfered, so as to fill the gaps between the wood plywood in the future basic treatment. Its edge chamfer is 450*3. Nailing method is the same as wooden wall.
5) Finishing and convergent:
The decorative surface of wooden keel frame partition is generally wood paint, wood wallpaper, wood spraying and wall veneer. The closing position of the partition wall is mainly between the ceiling surface, the building wall and the partition wall and its own doors and windows.
