Construction BlogRepairing Drywall, Fixing of DrywallRepairing a hole in drywall is simple. The first thing that you need to do is cut the hole bigger. Cut the hole like 8x8 or 10x10 inches. The next step is to back the hole. Use 2x4's and screw them into the existing hole all the way around half on. Cut a new piece of drywall either 8x8 or 10x10 and screw it into the backing. The next step from here is to install the joint compound. Spread a 6 inch wide strip of mud around the perimeter of the joint. Lightly press the tape into the mud around the perimeter. Let this dry and then sand it down. Apply the second coat and work it out each way by feathering it so that each side is flush with the existing wall. Sand it down after it dries. Since this is a small hole I would recommend buying a texture can and spray on the texture to match as small as possible. You can buy these repair cans at most hardware stores. Oriented Strand Board (OSB)Osb is short for oriented strand board. Osb has become extremely popular over the last decade. Osb comes in sizes of 3/8, 1/2, 5/8, and 3/4. The standard size sheet of osb is 4x8 foot. Other sizes can be special ordered for special applications such as 9's and 10's. Osb also comes in tongue and groove for floors. Sizes for this range from 5/8, 3/4, and 1 1/8. Osb has a rough surface on it so the installation of this on roof is made it the most popular choice of sheeting. Platform FramingPlatform is a western style of framing. This framing style replaces balloon framing and ribbons. Platform framing in a nutshell is framing that is interrupted between floors and is not continuous. balloon framing is continuous studs and the floor hangs off of them supported by ribbons which are usually 1x6 stock. Dormer FramingFraming a dormer is like framing a little house on top of a roof. Here is how you frame a dormer. 1. Make sure that where the side walls of the dormer are going to sit that the trusses or rafters are doubled to take the load and space them the out out dimension of the dormer. 2. Install the head outs for the ridge and bottom wall. Use a doubler. 3. Frame the side walls first on top of the doubled rafters after sheeting it of course. Then frame the front walls. 4. Sheer the walls and flash the side walls with 6 inch l metal. Make sure that the the side flashing laps over the bottom flashing. This is the proper roofing procedure. 5. Run the trusses like regular until you get to the last truss. Run a dummy ridge into the doubler and nail the other end into the end truss. 6. Run the valleys and cut the valley jacks into them. 7. Bird block it as standard. 8. Run the fascia 9. Sheet the roof 10. Install the front window 11. These are the major steps involved in framing a typical doghouse dormer. Framing doorsFraming doors is a simple task. The only difficult part is making sure that the rough opening is right. Follow these steps to frame a door. 1. For most doors (almost all exterior and interior doors this will work). 2. Install the the header. If this is and exterior wall then use either a 4x8 or a 6x8 cut inches over call out. Put the header at 82 1/2 inches above the sub floor. 3. Install the trimmer studs. Nail them every 16 inches into the king studs with 16d nails. 4. Thats all there is to it. This will work for most prehung doors. The key is to get the rough opening dimensions or measure the door prior to framing the opening to eliminate mistakes. Either way most doors will fit in the opening that I described above. Shed roof framingFraming a shed roof is the simplest type of roof to frame. Anyone can frame a simple shed roof by following these steps: 1. Frame the exterior walls. If this is a shed that the roof is going to sit on then build the rear wall what ever height is needed above the front wall to get the pitch that you want. For example if the roof is a 3 and 12 and the depth is 10 feet then the height of the back wall will be 30 inches higher than the front wall. 2. With the wall built and the side walls being rake wall then the rafters can now be cut. Cut the rafters out of 2x6. This is plenty strong for a shed roof with a span of ten or so feet. Use a speed square and put the ridge cut and bottom seat cut on the rafter. Make the seat cuts full. 3. Roll the rafters at 24 inches on center and toenail them down into the top plates. 4. Hang the fascia and nail it into the rafters. 5. Sheet the roof out of 3/8 plywood. This is plenty strong for a shed roof. Since there is no overhang on a shed roof no bird blocks are needed. 6. Install the shingle mold flush to the sheeting. 7. Use roll roofing and lap a minimum of 4 inches between rolls. 8. Thats all that there is to framing a shed roof. Custom FramingCustom Framing is a way over used term. A custom house means that there has never been a house built with that floor plan before. Custom framing could include rake walls, circular walls or any kind of framing that is sub-standard. Custom framed homes are still built the same way as tract homes. Just because the name custom has been given to it does not mean anything. I built many custom homes and the only thing different was the roof. The roofs on custom homes tend to have more lines on them. Besides the roof there is no difference Between conventional framing and custom framing. Timber framingTimber framing is a style of framing that uses post and beam construction. This kind of framing is usually done so that the finished woodwork can be seen through the house. Everything is exposed and no dry wall is installed. In Most cases nowadays except for log cabins obviously the walls are framed regularly except that the bearing points for the ridge and valley or hip consist of posts. The ridge is set on two posts and if the span is really long then the ridge will usually have a few midspan posts. The rafters are then cut traditionally out of rough sawn lumber usually 4x8 or 4x10 stock. They are usually spaced 32 or 48 inches on center. The rafters are then sheeted with t&g all the way up the rake. The t&g is usually framed on top of conventionally so that the roof can then be insulated with R-38 or Celotex. This kind of framing elegantly expressed the beautiful woodwork. The ceiling are usually stained and clear finished. Timber framing is one of the most beautiful kind of construction that there is. Roof FramingRoof Framing describes the construction of build a roof (cutting) or rolling trusses on top of exterior walls. To frame a roof one must make sure that the walls are perfectly plumbed and lined. After this is done the roof can then be framed. If the roof is a truss roof mark the top plates of the exterior walls every two foot and go. Raise the first truss into position with a helper holding the ridge. Make sure that the truss positioned on the wall right. The tit should be flush to the framing. Brace the truss plumb at the ridge. If this is a gable truss then the outriggers should be cut into the truss 48 inches on center. If this is a hip roof set the girders first and lay everything out of of the girders. Roll one truss at a time and run a sticker out and nail the truss to the wall and then tack it to the sticker. The closer the sticker is to the ridge the more effective that it will be. Continue rolling the trusses until the entire roof has be installed. Next nail the bird blocks in square to the wall line. Put a vent block every two solid blocks. This provides adequate ventilation for most roofs. After the bird blocks have been installed snap a line on the tails where the fascia will be installed. 16 inches is a good size over hang for a tract house. Next nail the fascia to the tails and hang the rakes last. Planching the rakes first makes it easier as one does not have to do it later off a latter. After the fascia has been installed snap a line a 48 inches off the center of the fascia. This is the line for your first row of sheets. Stagger the sheeting so that the breaks do not line up with the row below it. Continue sheeting until you reach the ridge and rip the last sheet to fit. Thats roof framing. Framing HammersThe basic hammer used for framing is often called a claw hammer or a ripping hammer. I like to use a decent weight of 19 to 23 oz. Vaughn makes a good framing hammer for the price. If you have carpenters elbow and don't mind spending the money try a titanium hammer. I like the stiletto 16 oz hammers. These things will drive nails all day long with no impact on your elbow or arm. These things have very low vibration. I like axe handles on my hammers because I seem to get a better grip with them. It is all personal preference though as many carpenters like strait handles. Recently I have been Framing with a rigging axe. These things are heavy at 32 oz. but for remodeling they sure do get the job done. Framing hammers have waffled heads to catch the waffle on the nail, this is how you can spot if it is a framing hammer. The claws also go almost strait back at 180 degrees. The claws can be sharpened and used as a chisel. |
