Abstract
Holding members for engaging the corners of base plates of nail plates while wooden beams are force down on the upwardly projecting nails to form a truss are made of resilient plastics material of about the same thickness as the base plate and provided with a self-adhesive surface for fixing them relatively to a preparation table. Each holding member is formed at one side so as to lie against the edge of the base plate at at least two points respectively on both sides of the the associated corner. A comparatively thin supporting layer of harder material may be secured on the upper face or between or on both faces of the resilient material.
Claims13
A device for the purpose of manufacturing a truss system of wood wherein the parts of the truss are to have nails forced into them with a press, the device comprising a setting plate, a nail plate including a base plate formed with at least three corners and carrying nails projecting perpendicularly therefrom to be forced into the truss system with the press so as to secure said nail plate thereto, and at least one selfadhesive holding member adhesively fixed to said setting plate for locating said base plate on said setting plate, said holding member being formed from resilient plastic material having a planar configuration and having an adhesive substance on one planar face thereof and including means at one side thereof for lying against the edge of said base plate at at least two points respectively on both sides of at least one said corner thereof and is compressible so that when the press forces the nails into the wood, said base plate can also be forced into the wood.
A self-adhesive holding member for positioning on a preparation table a base plate which has at least three corners and has nails projecting therefrom to be forced into wooden beams of a truss system in the manufacture thereof, said holding member being formed from resilient plastics material having a planar configuration coated on one face thereof with an adhesive substance, said holding member including means for lying against the edge of said base plate at at least two points respectively on both sides of at least one said corner thereof and is compressible so that the base plate can be forced into the wooden beam.
A self-adhesive holding member for positioning on a preparation table, a base plate which has at least three corners and has nails projecting therefrom to be forced into wooden beams of a truss system in the manufacture thereof, said holding member being formed from resilient plastics material having substantially parallel faces, one of said faces being coated with an adhesive substance such that, on being adhesively secured in position with respect to said preparation table, said holding member lies against the edge of said base plate at at least two points respectively on both sides of at least one said corner thereof, and said holding member including a supporting layer substantially parallel to said faces and made from a harder material than said resilient plastics material.
