Embodiment Construction

[0033] figure 1 is a perspective view of a sprue button spacer or connecting member 20 according to the present invention. To accommodate the methods of the present invention as described herein, the gate button spacer is formed from a material that will withstand the temperatures required for the injection molding step. In a representative embodiment, the sprue button spacer is molded from a thermoplastic or thermoset resin having a higher melting point than the plastic from which the entire flange is injected. The resin used for the spacer can be any polymeric resin that can withstand the structural stress of the mold and the temperature of the injection molded plastic used for the flange. The choice is well understood by the skilled person, but thermoplastics with higher melting points may include, for example, fluoropolymers, liquid crystal polymers, polyamides, polyimides, polyarylates, polyetherketones, polyetheramides imines and polysulfones.

Abstract

The present invention provides a method of forming a floor drain attachment and the resulting structure. The method comprises the steps of: aligning two preformed fabrics superimposed on each other, positioning a connecting member between the fabrics and bonding to each of the two fabrics, positioning the connected two fabrics in a mold and using the connecting member to The joined fabrics are centered inside the mould, plastic material is injected through openings in the joining member, and the space between the two fabrics is filled with plastic material.

Description

technical field [0001] The present invention relates to the construction of waterproofing systems in mortar bonded environments. Such environments typically include tiled floors and walls and associated fittings and floor drains (eg, in a shower room). Background technique [0002] Conventional methods of installing tile shower floors typically include several steps. First, a sloped screed course is installed that slopes from the edge (eg, a wall, side rail, or some other boundary) toward the location of the floor drain in the subfloor. This screed layer is typically referred to as sloped fill or "pre-slope". A waterproof barrier, commonly referred to as a shower pan liner, is then positioned over the sloped screed layer and secured to the floor drain. Conventional shower pan liners are not designed to bond to the substrate or tile or stone tile and therefore a second non-bonding ("floating") mortar layer must be superimposed to provide a load distribution layer and bondi...
