Abstract

Adhesive bonding of tubular frame members and corner castings has several advantages. The main ones are that the bonding does not cause any distortion of the alignment of the members nor does it affect any finish on the members such as results from welding.. The bonding adhesive is generally applied to the surface areas of the members to be joined. The amount is estimated. The result is that an excessive amount is usually used and requires a considerable amount of cleanup after the bonding. This arrangement provides for reservoir 10 to be located in casted joint 12 of such a dimension that tubular member 14 fits in it.

Adhesive Bonded Structural Joint

Adhesive bonding of tubular frame members and corner castings has several advantages. The main ones are that the bonding does not cause any distortion of the alignment of the members nor does it affect any finish on the members such as results from welding.. The bonding adhesive is generally applied to the surface areas of the members to be joined. The amount is estimated. The result is that an excessive amount is usually used and requires a considerable amount of cleanup after the bonding. This arrangement provides for reservoir 10 to be located in casted joint 12 of such a dimension that tubular member 14 fits in it. Member 14 carries rubber seal 16 around its periphery located at the right distance from its end so that it sits on the outer end of joint 12 when they are mated providing a seal against the loss of adhesive 18. Reservoir 10 in joint 12 is filled to the top with adhesive 18. The amount of adhesive 18 is predetermined by the height of the reservoir so that it is sufficient to wet the various surfaces to be bonded. Member 14 is placed into joint 12 until it is seated on shoulder 20. The pressure exerted upon adhesive 18 by tube 14 displaces adhesive 8 to areas 24 and 25 about member 14. This arrangement eliminates adhesive cleanup and in addition increases the bonded area to provide a stronger joint.
