[Technical field to which the device belongs]

 The present invention relates to a connectable sheet receiving member that can fix a vinyl sheet or a polyolefin film sheet or the like to be spread on a vinyl house or the like with a corrugated wire or a specific film stopper, and particularly, the vinyl sheet is overlapped and expanded in the vinyl house or the like. The present invention relates to a connectable sheet receiving member that can be used as a long sheet receiving member in the case of fixing a sheet with a double corrugated wire.

[0002]

[Prior art]

 Heretofore, various vinyl sheet receiving members have been proposed and used in the past. Among them, a sheet receiving member having a dovetail-shaped cross section is generally known. And, it is said that the sheet receiving member having a dovetail-shaped cross section formed by bending a metal plate is excellent as the one using this type of vinyl sheet receiving member. As shown in FIG. 2, the sheet receiving member 1 has a sloping wall that is symmetrically directed inward, and a vinyl sheet 4 is trapped in the dovetail groove 2 formed by the sloping walls. The fixing corrugated wire rods 3 which are continuous with each other are inserted, and the elastic force of the corrugated wire rods 3 fixes the vinyl sheet 4 to the left and right inclined walls in the dovetail groove 2 by pressure. Reference numeral 5 indicates both ends of the corrugated wire rod 3. However, all of these conventional sheet receiving members fix one sheet in the dovetail groove with one corrugated wire.

However, a long sheet receiving member has been required due to the widespread use of large-scale vinyl greenhouses, but there is no choice but to use a plurality of sheet receiving members connected to each other in order to achieve a certain length or more. . For this purpose, Japanese Patent Laid-Open Publication No. 5-14759 proposes a type of sheet-fixing groove member having a dovetail-shaped cross section to be connected. As shown in FIG. 3, one end of a sheet fixing channel member 1 having a dovetail-shaped cross section is cut off at least the groove bottom wall 2 and the remaining portion is cut off, and both side walls 3 of the groove bottom wall 2 are cut out. The sheet is reduced by the thickness and inserted into the end portion 4 of the sheet-fixing channel member facing the sheet.

In addition, as proposed in Japanese Utility Model Publication No. 5-18933 and Japanese Utility Model Publication No. 6-23254, as shown in FIG. 4, an end portion of a sheet fixing channel member 5 having a dovetail-shaped cross section is used. Is an outer joint portion 7 in which the inner portion of the curl portion is formed on an outer sliding surface 6 for fitting which is parallel to the longitudinal direction, or the outer sliding surface 6 for fitting is not provided. The end portion 8 of the other sheet fixing channel member connected to the sheet fixing member is reduced in thickness by about the plate thickness while keeping its cross-sectional shape similar, and the outer portion of the curl portion is fitted to the outer joint portion. The inner joint portion 10 is formed on the inner sliding surface 9 for fitting in a straight plane parallel to the longitudinal direction at a distance slightly smaller than the distance between the outer sliding surface 6 for external use, and the two groove members for fixing the sheet are external. Insert the inner joint portion 10 inside the joint portion 6, The inner sliding surface 9 for fitting is connected to the outer sliding surface 6 for fitting in parallel and in close contact with each other.

[0005]

[Problems to be solved by the device]

 However, in the channel material disclosed in Japanese Utility Model Publication No. 5-14759 shown in FIG. 3, the groove bottom wall is left and the remaining portion is cut off, and both side walls of the groove bottom wall are reduced in thickness. Since it is simply attached to the opposite ends of the sheet fixing channel, there is no strength of the connecting part, so when the vinyl sheet is fluttered by wind or the like during use of the greenhouse, the vinyl sheet is wavy. However, there is a drawback that the connecting part comes off.

Further, even in the groove members disclosed in JP-B-5-18933 and JP-B-6-23254 shown in FIG. 4, the inner joint portion is provided inside the outer joint portion of the sheet fixing groove member. When inserting, the processing accuracy is required when the cross-sectional shape of those ends is reduced to approximately the same thickness while maintaining a similar shape, which makes connection work in the field extremely difficult, which results in incomplete mounting. There was a drawback that the connection part came off. Furthermore, since the ends are pressed in this way to form the connecting parts, when the inner joint is inserted and connected to the outer joint, a gap is created between the tip of the outer joint and the base of the inner joint. Due to the gap, there was a point that the fixed sheet touched and damaged, or the pressed inner joint part was broken by the force of the wind.

The present invention has been made in view of the above circumstances, and can fix a vinyl sheet, a polyolefin film, or the like with a corrugated wire or a specific film stopper, and particularly with a plurality of corrugated wires in a vinyl house or the like. Even when fixing a sheet, a plurality of sheet receiving members can be easily and firmly connected, a long sheet receiving member can be easily obtained, and the sheet can be easily attached to the house structure material. An object is to provide a sheet receiving member.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a sheet receiving member in which both side walls of a bottom portion are respectively raised inward in a circular arc shape and an outer circular lip is formed at an upper edge portion following the side wall. An inner joint having both side walls rising inward in an arc shape is fixed to a bottom portion of one end of the sheet receiving member so as to project from one end of the sheet receiving member. It is characterized in that the bottom portion of the inner joint, in which both side walls stand inward in an arc shape, is fixed to the bottom portion at one end portion of the sheet receiving member by caulking to project from the one end portion of the sheet receiving member.

[0009] Furthermore, the bottom portion of one end of the sheet receiving member is protruded from one end of the sheet receiving member by spot welding the bottom portion of the inner joint in which both side walls stand inward in an arc shape. It is characterized in that it is fixed, and a long hole for connection is bored in the protruding part, and both side walls of the bottom part rise inward in an arc shape, and the intermediate part following it rises in the opposite direction and the upper edge. In a sheet receiving member having an outward circular lip formed on its portion, an inner joint with both side walls rising inward in an arc shape is formed at the bottom of one end of the sheet receiving member. The present invention is characterized in that it is projected and fixed from one end of the bracket member, and a connecting elongated hole is formed in the projecting portion.
