Balloon Frame

It is a type of Light Wood Framing where it is the lightest form of framing, in which the studding and corner posts are set up in continuous lengths from first floor line or sill to roof plate.

Ribbons

These are boards that are notched and nailed into the studs and corner posts at the proper height to support the second story joists

Joist

It is brought against a stud wherever possible.

Balloon Frame

This type of frame is lacking in rigidity and is liable to sway and tremble in heavy winds.

Combination Frame

It is a type of Light Wood Framing where it is a modification of the old braced frame which was of heavy timbers with every joint mortised and tenoned.

Drop grits

The girts which support the floor joist

Flush Grits

Grits that is parallel to the joists

Combination Frame

This type of construction is more rigid than the balloon frame.

Platform Frame

It is a type of Light Wood Framing where the ground and second floor level structures are supported by their respective platforms.

Heavy Wood Framing of Beam and Girder Framing

This is the type of framing used in the Philippines in which the floor joists are carried by girders, and the roof trusses or rafters by girts which frame into the posts.

Griders

The floor joists are carried by?

Posts

The roof trusses or rafters by girts which frame into the?

Plain Joint (Lap Joint)

It is a type of Wood Joint where used in very hasty construction for temporary framing and is made by lapping one piece over the other and nailing then together.

Plain Joint (Lap Joint)

It is not a very strong joint.

Butt or Square Joint (End Joint)

It is a type of Wood Joint where it is made by made by placing full thickness of wood directly against the second piece.

Butt or Square Joint (End Joint)

A wood joint where it should be squared and the sides against which it butts smooth so that the pieces will be perpendicular to each other.

Butt or Square Joint (End Joint)

The joint is toe-nailed.

Oblique Joint

It is a type of Wood Joint where it is made when the two pieces do not meet at right angles, e.g. bracings

Oblique Joint

A joint where one piece is cut at an angle to fit the other and the two pieces nailed securely together.

Mortise and Tenon Joint

It is a type of Wood Joint where the joint is used for building wooden framework where great strength and rigidity are all important.

Mortise and Tenon Joint

A joint where it is made by cutting a hole or mortise in one piece and a tenon or tongue in the second piece to fit the hole in the other.

Halved Joint

It is a type of Wood Joint where it is made by cutting half the thickness of the wood from each piece at the ends to be joined so as to bring the sides flush

Halved Joint

The purpose of this type of joint is to maintain a level surface at the joint.

Rabbet Joint

It is a type of Wood Joint where it is made by cutting a shoulder or edge from one piece to receive the other piece.

Rabbet Joint

A joint where it is It is used in window or door frames, or in shelf and drawer construction.

Dado Joint

This joint is similar in shape and purpose to the rabbet joint.

Dado Joint

It is a type of Wood Joint where a groove is made in one piece at right angles to the grain of the other board.

Miter Joint

It is a type of Wood Joint where a joint between two pieces which come together at a corner.

Miter Joint

It is a finish joint and should not be used where strength is an important requirement.

Miter Joint

A joint that is made by cutting the two ends at angles complementary to each other,

Miter Joint

This joint is secured by clamp nails or finishing nails, corrugated fasteners or dowels, or by gluing.

Dovetail Joint

It is a type of Wood Joint where it is used for cabinet work and furniture work, is strong and durable

Dovetail Joint

A joint that is made by cutting a pin in the shape of a dovetail in one piece to fit a groove similarly shaped in the other piece.

Coped Joint

It is a type of Wood Joint where it is used when fitting one piece of moulding at right angles to the second piece.

Splice

to connect two or more pieces of timber in such a way that the joint will be as strong as a single timber of equivalent size

Scabbed of Fished Splice

It is a type of Splice for Compression where two pieces of timber are squared at their ends and fitted together.

Fishplates

Two short wood pieces called scabs / metal plates

Scabs or Metal Plates

Two short wood pieces called ______ or _______

Halves Splice

It is a type of Splice for Compression is better for direct compression, and when combined with scabs or fishplates, may be used where there is some tension.

Halved Splice

This splice is made by cutting half the thickness of each piece to the required length and putting the halved sections together.

Square Splice

It is a type of Splice for Tension where it is a is a modification of the compression halved splice

Square Splice

A splice where it has an extra notch to keep it from slipping and is usually used in combination with scabs or fishplates.

Scarfed Splice

It is a type of Splice for Bending when a piece of timber is subjected to bending as in a horizontal piece supporting a weight,

Compression

The upper part of a Scarfed Splice is subjected to?

Tension

The lower part of a Scarfed Splice is under?

Square

The upper part of a Scarfed Splice should be cut?

Beveled

The lower part of a Scarfed Splice should be ______ on the end

Timber connectors

These are are metal devices used to provide added strength at bolted joints.

Timber connectors

They eliminate complicated framing of joints, simplify the design of heavy construction, and save much time and labor. Among the various types of timber connectors are:

Split Rings

It is a type of Timber Connectors that are made in sizes of 2-1/2, 4 and 6 in. in diameter.

Split Rings

It is a type of Timber Connectors where they are used for heavy construction.

Toothed Rings

It is a type of Timber Connectors that are toothed and corrugated

Toothed Rings

It is a type of Timber Connectors where they are made in 2, 2-5/8, and 4 4 in. dia

Toothed Rings

It is a type of Timber Connectors that are used between two timber frames for comparatively light construction

Claw Plates

It is a type of Timber Connectors where one side is clawed and other smooth

Claw Plates

It is a type of Timber Connectors that are used either singly, in timber to metal connections, or in pairs in timber to timber connections

Shear Plates

It is a type of Timber Connectors when installed these lie flush with the timber surface. They are used singly or in pairs.

Shear Plates

It is a type of Timber Connectors where in timber to metal connections the plate is placed with its back towards the metal.
