Method of making a screen for anchoring a fastener to a hollow block with an adhesive

A method of making a screen assembly for anchoring a fastener within a wall structure having a bore defined therein, comprising the steps of:

• providing a strip of plastic mesh having a predetermined length, width, and mesh size;
• helically winding said strip of plastic mesh;
• securing edge seam portions of said helically wound strip of plastic mesh together so as to form said strip of plastic mesh. into a tubular screen member having an elongated tubular portion defined about a longitudinal axis, opposite first forward and second rearward open ends, as considered in a direction of insertion of said tubular screen member within said wall structure, and a substantially uniform diameter along said length, said second rearward end of said tubular screen member being open so as to permit adhesive to be deposited into said tubular screen member;
• and
• heating said first forward end of said tubular screen member and inserting said heated first forward end of said tubular screen member into a die so as to provide said first forward end of said tubular screen member with a substantially conical pointed tip portion disposed along said longitudinal axis for facilitating insertion of said screen member into said bore of said wall structure, and to close said first forward end of said tubular screen member such that when a fastener is inserted into said tubular screen member, said adhesive, disposed within said tubular screen member, will be prevented from being axially discharged from said substantially conical first forward end of said tubular screen member and will be forcedly discharged radially through mesh portions of said elongated tubular portion of said tubular screen member so as to fixedly bond said tubular screen member and said fastener within said wall structure.

A method of making a screen assembly for anchoring a fastener within a hollow block structure having first and second apertures respectively defined within first and second wall members longitudinally spaced apart as considered in a direction of insertion of said screen member within said hollow block structure, comprising the steps of:

• providing a strip of plastic mesh having a predetermined length, width, and mesh size;
• forming said strip of plastic mesh into an annulus having a longitudinal axis;
• securing edge portions of said plastic mesh strip annulus together so as to form said plastic mesh strip annulus into a tubular screen member having an elongated tubular portion defined about said longitudinal axis, opposite first forward and second rearward open ends, as considered in said direction of insertion of said screen member within said hollow block structure, and a substantially uniform diameter along said length, said second rearward end of said screen member being open so as to permit adhesive to be deposited into said screen member;
• and
• heating said first forward end of said tubular screen member and inserting said heated first forward end of said tubular screen member into a die so as to provide said first forward end of said tubular screen member with a substantially conical pointed tip portion disposed along said longitudinal axis for facilitating insertion of said screen member into and through said first aperture defined within said first wall member of said hollow block structure, for further facilitating blind insertion of said screen member into and through said second aperture defined within said second wall member of said hollow block structure, and to close said first forward end of said tubular screen member such that when a fastener is inserted into said screen member, said adhesive, disposed within said screen member, will be prevented from being axially discharged from said substantially conical first forward end of said screen member and will be forcedly discharged radially through mesh portions of said elongated tubular portion of said screen member so as to fixedly bond said screen member and said fastener within said first and second wall members of said hollow block structure.

A method of making a screen assembly for anchoring a fastener within a wall structure having a bore defined therein, comprising the steps of:

• providing a tubular screen member, comprising a plastic material for resisting corrosion, an elongated tubular portion defined about a longitudinal axis, first forward and second rearward open opposite ends, as considered in a direction of insertion of said screen member into and within said bore of said wall structure, and a substantially uniform diameter along its length, said second rearward end of said tubular screen member being open so as to permit adhesive to be deposited into said tubular screen member;
• and
• heating said first forward end of said tubular screen member and disposing said heated first forward end of said tubular screen member within a die so as to provide said first forward end of said tubular screen member with a substantially pointed, closed tip portion disposed along said longitudinal axis of said tubular screen member for facilitating insertion of said tubular screen member into and Within said bore defined within said wall structure, and for preventing axial discharge of said adhesive, disposed within said tubular screen member, from said pointed first forward end of said tubular screen member when a fastener is inserted into said second open rearward end of said tubular screen member such that said adhesive disposed within said tubular screen member will be forcedly discharged radially outwardly through mesh portions of said elongated tubular portion of said tubular screen member so as to fixedly secure said tubular screen member and said fastener within said bore defined within said wall structure.

A method of making a screen assembly for anchoring a fastener within a wall structure having a bore defined therein, comprising the steps of:

• providing a tubular screen member, comprising a plastic material for resisting corrosion, an elongated tubular portion defined about a longitudinal axis, first forward and second rearward open opposite ends, as considered in a direction of insertion of said screen member into and within said bore defined within said wall structure, and a substantially uniform diameter along its length, said second rearward end of said tubular screen member being open so as to permit adhesive to be deposited into said tubular screen member;
• and
• heating said first forward end of said tubular screen member and disposing said heated first forward end of said tubular screen member within a die so as to provide said first forward end of said tubular screen member with a substantially tapered, closed tip portion disposed along said longitudinal axis of said tubular screen member for facilitating insertion of said tubular screen member into and within said bore defined within said wall structure, and for preventing axial discharge of said adhesive, disposed within said tubular screen member, from said tapered first forward end of said tubular screen member when a fastener is inserted into said second open rearward end of said tubular screen member such that said adhesive disposed within said tubular screen member will be forcedly discharged radially outwardly through mesh portions of said elongated tubular portion of said tubular screen member so as to fixedly secure said tubular screen member and said fastener within said bore defined within said wall structure;
• and
• providing said second open rearward end of said tubular screen member with integral tab means for facilitating manipulation of said tubular screen member during insertion of said tubular screen member within said bore defined within said wall structure.
