Abstract
Disclosed is a drain plate and a method of forming a drain plate that reduce production cost and productivity, as compared with the conventional drain plate. The disclosed drainage plate is composed of a flat plate which is integrally formed of a thermoplastic resin and has a flat plate and a plurality of cups spaced apart from each other on the plate and protruding downward to the same depth, (cup). A plurality of female couplers (female couplers) disposed on the outer circumferential portion of the plate and projecting downward, and a plurality of downwardly female couplers (female couplers) for fitting the male couplers. and a coupler. The male coupler and the female coupler all have an engraved upper side and an embossed lower side.
Description
BACKGROUND OF THE
The drain plate is used to form drainage passages on the floor at the construction site. 1 is a cross-sectional view schematically showing a construction of a drainage board. Referring to FIG. 1, a
A plurality of drain plates (5) are connected to cover a large floor area. However, when a plurality of
Referring to FIG. 2, the drain plates 100_1 and 100_2 are provided with
The drain plates 100_1 and 100_2 are formed by injection molding of a plastic material so as to integrally form not only the
SUMMARY OF THE INVENTION The present invention has been made to solve the problems associated with the conventional drain plate having the above-described injection molding, and it is an object of the present invention to provide a drain plate which is manufactured by a vacuum molding method, .
Another object of the present invention is to provide a drain plate and a method of forming a drain plate in which a plurality of drain plates can be firmly fastened to each other by forming a fastening and fixing structure by a vacuum forming method.
The present invention relates to a thermoplastic resin sheet which is formed integrally with a thermoplastic resin and has flatly extended plates and a plurality of protrusions formed on the plate so as to protrude downward from each other at the same depth, A drain plate having a cup, comprising: a plurality of male couplers disposed on an outer circumferential portion of the plate and projecting downward, for connecting adjacent pair of drain plates; and a male coupler And at least one of a plurality of female couplers which are downwardly fused so as to be fitted, wherein the male coupler and the female coupler both provide a drain board having an upper face formed with a recessed shape and a raised lower face.
Wherein the plate is a quadrangular shape having four straight corners, the plurality of male couplers are arranged along two adjacent straight corners of the four straight corners, and the plurality of female couplers are arranged along the remaining two straight corners .
The thermoplastic resin may be polyethylene terephthalate (PET).
Further, the present invention provides a method of molding the above-mentioned drain pan, comprising the steps of: forming a flat top surface corresponding to the plate, a plurality of cups, and a plurality of shapes corresponding to at least one of the plurality of male couplers and the plurality of female couplers A mold preparing step of preparing a molding mold having an air inlet hole on an inner circumferential surface defining an inner space of the plurality of molding grooves, a step of preparing a molding sheet having a sheet of thermoplastic resin on the upper side of the molding die A heating step of heating and softening the sheet; and a heating step of partially extending the sheet by sucking air through the air intake hole, And a shaping step of sucking the molten metal on the inner circumferential surface of the molding groove of the mold.
The method for molding a drain pan of the present invention may further comprise a curing step for curing the softened sheet after the molding step and an unloading step for separating the cured sheet from the molding die .
In the method for forming a drain pan of the present invention, the curing step and the unloading step may be performed simultaneously by blowing air of room temperature or lower temperature through the air intake holes into the plurality of molding grooves.
The drain plate of the present invention is manufactured not by injection molding but by vacuum molding of a thermoplastic resin sheet to reduce production cost and improve productivity.
Also, the drain plate of the present invention can be formed by vacuum forming the connection protrusions and the connection grooves for connecting the neighboring drain plates to each other, so that the entire drain plate can be manufactured by vacuum molding, thereby reducing the production cost and improving the productivity.
