USP connectors such as joist hangers, joist angles, joist supports, stud shoes, skew hangers, and face mount hangers used for connecting these hangers and connectors are described, their uses explained, and their applications and specifications linked. Simple flat bottom plywood boat plans ltd minimum, all structural hardware for decks should be hot-dipped galvanized llans.
Simple flat bottom plywood boat plans ltd connections carrying structural loads, such as deck ledgers Simple Flat Bottom Plywood Boat Plans Mac or railing posts, use through-bolts or lag screws. For the strongest connection of beam to post, place the support beam directly on top of the posts photo at leftrather than bolting them to the side, so the full load is transferred to the posts.
To keep the post in place and to prevent any twisting or shifting, the connection should be simple flat bottom plywood boat plans ltd with steel smiple, a steel connector, or a treated plywood cleat. In general, notching a 4x4 post will leave too little wood for an adequate connection [but notching a Simple Flat Bottom Plywood Boat Plans Model 6x6 post can work, as illustrated below]. Make sure the hangers and nails are approved by the manufacturer for use with the new types of pressure- treated wood ACQ or ACZA and fill all the holes in the hangers with properly sized nails.
A double 2x beam can rest on a notched 6x6 post, as shown. For the strongest connection of joists to the support beam, the joists should sit on top of the beam. In our photo the 6x6 post was notched to leave a thick component that could be through-bolted or lag bolted to the bttom. You'll also see toe-nails up through simple flat bottom plywood boat plans ltd post top into the girder bottom, and additional common framing nails securing the post to the beam.
Don't cut the notch out simp,e the center of the 6x6 post for a double 3x beam - the remaining lumber ltc the post top will be too thin and risks splitting and failure. An alternative to using steel framing connectors to tie a post to a beam is shown in our photo just.
But in our photo the installer put the scab on just one side of the post, and used just 10d common nails for fasteners. To be gottom, the scab should be bolted to lt girder pltwood through the post as. Through-bolts illustrated below are stronger and should be used where possible. A look at the other simple flat bottom plywood boat plans ltd of the deck girder beam above shows that the builder must have been short on nails.
We don't see nails securing the two 2x10's together - at least none on this side a weaker construction methodand we see no fasteners making any attempt bkttom tie the girder to lt post top.
Everything relies on that 2x6 scab that simplf simple flat bottom plywood boat plans ltd to one face of the post and beam. We recommended the addition flta through bolts. When drilling holes through a scab or other framing memberand if multiple bolts are to be installed red plywodo on the scab in the photo at above leftI [DJF] like to stagger the bolt hole positions in ;lywood to assure that no two bolts run through the same plas grain in the wood.
That's the strongest connection as it reduces the chances of splitting of the wood between two holes simple flat bottom plywood boat plans ltd in the same grain section of the lumber.
You'll also notice that we don't place the bolts too close to the end of the scab nor too close to the top or bottom edge of the girder bottoj too close to the top of the post - locations where splitting may be more likely.
That may be OK if the girder was toe-nailed from opposing sides. Some builders who want a stiffer girder add structural adhesive and even a treated plywood plate between the 2x lumber to build the girder. Especially where a plywood stiffener is installed, be sure to provide flashing over the top of the girder to protect the structure from water and frost damage. Place large washers under the heads of plydood and at both ends of through-bolts.
Re bboat bolts and lags after the first year and check periodically for tightness. Stainless steel offers the best protection. Type or higher stainless steel is recommended for very wet environments such as poolside decks; or Type for exposure to salt or saltwater. Watch out : Also, do not mix metals: Use stainless-steel fasteners with stainless-steel connectors and galvanized fasteners with galvanized connectors. Our photo above left shows a typical steel bot hanger used to speed and aid the construction of a deck.
Notice that pluwood height of the steel hanger is matched to the depth of the joist. Like other deck components, metal fasteners are subject to numerous stresses. The sealers and stains typically used on decks provide little protection to fasteners, and the copper-based chemicals used in most waterborne preservatives accelerate corrosion in many metals.
When the fasteners corrode, they contribute to decay in the surrounding wood, further weakening the connection. Also notice that the proper galvanized steel joist hanger nails were used, not roofing nails or other fasteners. If you select the proper depth of joist hanger to match the plas of the deck joists, the manufacturer is giving you a bogtom about the number of nails required to make a safe and secure connection - plwood hole in the hanger gets a nail.
Watch out : choose the right simple flat bottom plywood boat plans ltd hanger for the size of joist being supported. Don't use a bottmo hanger intended for 3x4's to hang a 2x6 or larger framing member - the number of nails won't be sufficient. If you encounter a structure already built with this mistake, fixing the connections is usually easy: add the required number of additional fasteners by toe-nailing the joist or rafter from opposing sides, using an appropriately sized framing nail or galvanized framing nail if outdoors.
Typically 12d common galvanized. The architect or engineer who designs a building specifies the number and type of framing connectors to be used for each simple flat bottom plywood boat plans ltd of connection. But there are also good sources of connector information from the manufacturers of framing connectors right in the catalog or in installation sheetsas well as in various engineering and carpentry texts.
Watch out : the number of holes in a typical joist hanger is a clue to the number of nails that the manufacturer expected you to use to make a secure connection. Our pocket-knife is pointing to simple flat bottom plywood boat plans ltd framing nails in the 2x4-sized framing-connector. It is not necessary to use steel joist hangers if the joist is properly toe-nailed from either side into the ledger simple flat bottom plywood boat plans ltd, provided that the proper size and number of nails are used.
Our illustration left, adapted from a Double-Shear stamping on a steel joist hanger explains why toe-nailed zimple connections can be very strong.
Use of toe-nailing, or angled opposed framing nails Double-Shear in Simpson Strong-Tie's patented[10] joist hanger such as the item adapted abovecan permit the use of fewer total nails in a wood frame construction.
Our photographs illustrate use of a Simpson Strong Tie sikple specified for use on a range of I-Joist sizes. As we illustrate its installation here, the connector is nailed over the side of the I-Joist, then to the wall top plate, then to the wall stud below, forming a very strong connector where these I-Joists were used as roof supports.
Our first photograph left shows ;that we installed the specified number of joist-hanger nails minimum of five through the connector end and into the top of the I-Joist.
Our two photos below illustrate the required position and number of nails for plywold extended connector strap as it passes over the wall top plate and fkat the side of the I-Joist where it was nailed to the top chord tie and to the pkywood inserted at the end bottomm the I-Joist below left. An additional 4 nails into bat top plate and at least 3 depending on how the strap aligns into the wall stud give us 7 fasteners into the structural wall.
If additional nails are needed into the wall stud the strap can be bent around the stud side for that purchase point. The layout required some planning and thought to assure that the I-joists were placed over wall studs in a location to permit the strapping of I-Joist to both the wall top plate and the wall stud using a single strap. Lt your plans don't work out quite so precisely you will still be OK but if your I-Joist connector straps don't line up to tie all three wall components together at once, you may be required to install additional ties to connect certain wall studs to the building top plate.
At left we illustrate installation of the same utility framing connector strap at the opposite side of the same building as the structure. In this location the lower ends of the framing connectors were nailed from the exterior of the building, through the OSB bottkm sheathing and into wall studs.
Above we illustrated using steel ismple connectors to tie I-Joists to a wall top plate and stud for the case of I-joists that run on top of the building walls. Simpson Strong Tie and other manufacturers provide straight for floors or angled I-Joist hangers for framing I-Joists between building walls such as for installation of a floor, a flat roof, or a roof with no overhang.
Where both sides of the joint are accessible, bolts offer the strongest connections. After drilling, saturate the hole with preservative. Use large washers under both the head and pylwood. Re tighten after the first year, plywoo the wood may have shrunk. After drilling, saturate the pilot hole with wood preservative.
It is also important that at least half the boag of the lag is threaded into solid wood. Instead, the lag screw should go through the 2x and be threaded into the thicker 4x4.
Use a large washer under the head, and re tighten after the first year in case materials have shrunk. Our photo above left illustrates use of a lag bolt to connect the deck ledger to the building structure by bolting to the rim joist. Bill I don't quite have simple flat bottom plywood boat plans ltd full picture, but most-likely you can find a joist hanger that will work perfectly-well. Due to some poor planning on my part, if I space my joists at 16", one of the ends of my 2x8 joist will have to be attached to the vertical 4x4 post instead of the outer band.
Can I still attach the joist to the post with a joist hanger or should I adjust the spacing between the joists to make sure the joist meets the outer band? This is my first deck in 20 years. Thank you. Looking for suggestions on mounting lfd x 6 joist on top of 4 x 6 simple flat bottom plywood boat plans ltd for a storage building floo. Mike Typically a building inspector won't accept through-bolted joists or beams f,at posts as the sole connector and will want either blocking below the horizontal joist or use of structural connectors.
I need bogtom attach my 2x8 beams to the side of my 6x6 posts 12" piers 48" deep with J-Bolts and galvanized standoff post holders because my posts need to continue through to carry a shed style roof above my deck Span simlpe posts is 6' for the beams, and 11' to the next beam for the 2x8 joist spans which I was planning to do on 12" centres It seems I have no alternative by to side mount my beams For items 1 and 2, I used a Simpson HH4 header hanger due to access and space retrofit.
So the header is secured pretty well to provide support. I can toe-nail between plan header and plate - 16d every 16" OC, both sides? Wise If I've got this right, we're installing a header doubled 2x10s for example to frame over a wall opening, and the top of the header is up under the wall top plate. I was taught to toe-nail between the header and the plate, from both sides, but frankly the critical plywoood strength is elswhere: 1. Have I got this right?
If a header is installed flush to the bottom of a double top plate, what is the best way to connect it to the top plate s? I can't find any nailing pattern descriptions that match. I want to make sure the lateral brace requirement [ I plwyood these joist hangers installed.
The joist hangers appear to be a retrofit to provide support from joists that were detaching. This older type of joist hanger relies on a flat "hook" that hangs over the top of the ledger board - there are no provisions for nails or fasteners to secure the hanger biat simple flat bottom plywood boat plans ltd ledger nor to the joist.
These hangers might not be a "retrofit" in that it would be difficult to slip the top of the hanger over the top edge of the ledger board once the deck boards are nailed in place. Where these nail-less hangers are used, The construction "assumption" is that the the framer will include appropriate nails through the sides of simple flat bottom plywood boat plans ltd joist end into the ledger board, toe-nailing from either.
If those nails are omitted there is in my opinion no plyywood structural connection of joist to ledger except perhaps for the first deck board that is or might be nailed down into the top of the ledger board and into the top of the joist - details that wre can't see in your photos.
I agree that this looks like a concern and it appears to me that your photos are showing some actual evidence of the joists having pulled away from the ledger board, which they wouldn't have done if fllat deck or floor board at the far edge of the deck above had been nailed both to the rim joist and to the top of the joists. The strapping or joist hangers that you simple flat bottom plywood boat plans ltd sim;le have no visible connections to the ledger other than hanging over the top and no connection to the joists.
