First, the curing sheet connector of this example will be described with reference to FIGS.
As shown in FIG. 1, the curing sheet connector 1 of this example (hereinafter also simply referred to as “connector”) is a curing sheet 100 (for example, foamed polyethylene or the like) that protects the wall surface W at a construction site or a moving site. It is an instrument for connecting while sandwiching a sheet-like material made of polyolefin material such as polypropylene.

  As shown in FIG. 1 to FIG. 3, the connecting tool is provided with a support plate 10 that holds a curing sheet 100 made of a long plate having a substantially E-shaped cross section with a hollow center portion, and the connecting tool 1. The support plate 10 and the support sheet 20 that hold the curing sheet 100 upright are schematically configured.

  As shown in FIG. 1 or FIG. 2, the support plate 10 has a slight flexibility that makes it easy to attach and detach the curing sheet 100, and has excellent weather resistance that enables the posture to be maintained when the sheet is erected. It is a long plate made of a resin material (for example, hard vinyl chloride), and is formed by extrusion molding in a form including a pair of attachment bases 11 that sandwich the edge 101 of the inserted curing sheet 100. The support plate 10 is formed by appropriately adjusting the length direction dimension to a predetermined length (for example, about 1 m to 1.5 m) according to the installation site and the size of the curing sheet 100 to be used. Is done.

  As shown in FIG. 2A, the attachment base 11 has an insertion recess 12 into which the curing sheet 100 is inserted. As the formation position of the insertion recess 12 in the support plate 10, the abutting portion when the opening 12 a of the insertion recess 12 opens toward the insertion direction side (outside) of the curing sheet 100 and the curing sheet 100 is inserted. 12b is symmetrically arranged in a straight line so as to be back-to-back with the abutting portion 12b of the other mounting base 11. Further, the mounting base 11 is formed such that the width of the back-side clamping piece 13 facing the wall surface W when standing is extended by a predetermined length from the width of the opposing front-side clamping piece 14. ing. Furthermore, the distance between the front-side clamping piece 14 and the back-side clamping piece 13 is set to be approximately equal to at least the thickness of the used curing sheet 100. Further, both end portions of the front-side sandwiching piece 14 are formed to be gradually curved in a direction away from the back-side sandwiching piece 13 in order to facilitate the loading of the curing sheet 100.

  Furthermore, support edge which consists of a protrusion which continues in the up-down direction for assisting the clamping of the curing sheet 100 by the mounting base 11 on the edge 13a of the contact surface with the curing sheet 100 in the back surface side clamping piece 13 of the mounting base 11 A member 15 is provided. The supporting auxiliary member 15 is formed in a protruding shape by an elastic member having an elastic member restoring force such as soft vinyl chloride or rubber material, and the sheet is generated by the restoring force generated along with the deformation by the inserted curing sheet 100. When 100 is pressed against the front side clamping piece 14 side, it plays a role of preventing the curing sheet 100 from slipping. Note that the support auxiliary member 15 may have a hollow cross section.

  Moreover, by making the shape of the support auxiliary member 15 into a long cylindrical shape, the contact with the sheet 100 becomes line contact when the curing sheet 100 is inserted and removed, and the contact with the sheet 100 becomes surface contact after the sheet is inserted. The curing sheet 100 can be easily removed, and the curing sheet 100 can be securely clamped and fixed at the time of standing.

  Further, as shown in FIG. 2A, the diameter of the support auxiliary member 15 includes the thickness of the curing sheet 100 to be held, the depth of the insertion recess 12, the distance between the holding pieces 13 and 14, and the support auxiliary member 15. In order to securely hold the cured sheet 100 to be inserted, the width A between the front side holding piece 14 and the back side holding piece 13 in the insertion recess 12 is used as a reference. It is preferable that the diameter B of the member has at least approximately the same length from approximately half of the width A. In addition, in the figure, it is an example in which a support auxiliary member 15 formed with a length approximately half the width A between the front-side sandwiching piece 14 and the back-side sandwiching piece 13 in the insertion recess 12 is provided.

  Further, as shown in FIG. 2A, the upper edge of the wall side surface of the back-side clamping piece 13 of the mounting base 11 is damaged by the contact of the support plate 10 when the connector 1 is installed. In order to prevent this, a protective member 16 made of the same material as the supporting auxiliary member 15 is provided. In the drawing, one is provided along the upper edge of the wall side surface of the back-side clamping piece 13. In addition, since the protection member 16 should just prevent the damage of the wall surface W at least when the support plate 10 is set, the installation number and installation position can be changed suitably.

  As another example of the support plate 10, as shown in FIG. 2B, the shape of the back surface side clamping piece 13 in the mounting base 11 is gradually increased from the abutting surface side of the insertion recess 12 to the opening 12 a. There is also a form in which the shape of the support auxiliary member 15 is enlarged and curved, and the diameter of the support auxiliary member 15 is approximately half or more of the distance D of the opening 12a of the insertion recess 12. In this embodiment, when the minimum distance C between the back-side clamping piece 13 and the front-side clamping piece 14 is set to be smaller than the thickness of the curing sheet 100 to be used, and the curing sheet 100 is inserted into the attachment base 11 Further, the sheet 100 is clamped by using the restoring force due to the bending of the back surface side clamping piece 13, and the sheet 100 is further moved to the surface side clamping piece 14 side by the restoring force of the support auxiliary member 15 provided on the back surface side clamping piece 13. By pressing, secure clamping of the curing sheet 100 is realized. In the drawing, the ratio between the distance D of the opening 12a of the insertion recess 12 and the diameter B of the support auxiliary member 15 is an example of a relationship of about 2: 1.

  Further, as shown in FIG. 2 (b), at the place where the wall 1 is in contact with the wall W at the upper edge on the wall W side of the back-side clamping piece 13 of the mounting base 11, In order to prevent damage or the like of the wall surface W due to contact, a protection member 16 formed of the same material as the support auxiliary member 15 is provided. In addition, in the figure, it is the example which provided the protection member 16 in the contact location (2 places) with the wall surface W. FIG.

  As shown in FIG. 1 or FIG. 3, the support base 20 is disposed at the center of gravity of the base and has a trapezoidal-shaped storage section 21 for storing a weight of a predetermined weight, and a support plate provided on the back side of the storage section 21.

An upright holding portion 23 that contacts and holds the upright of the support base 20 is integrally formed by extrusion molding.

  Further, the back surface portion 21 a of the housing portion 21 and the support plate holding portion 22 constitute an insertion recess 24 into which the support plate 10 is inserted. Since the width in the depth direction of the insertion recess 24 is formed to be substantially the same as the width of the support plate 10, the support plate 10 to be inserted can be held upright and the support plate 10 can be inserted and removed. Is possible.

  The height of the upright plate 22a in the support plate holding part 22 is formed to be higher than the height of the accommodating part 21 in order to hold the standing of the support plate 10 (about twice in the illustrated example). What is necessary is just the height which can stand upright when 10 is inserted. Further, in consideration of the upright holding of the support plate 10, the inclination angle θ from the floor surface F to the back surface of the upright plate 22a is substantially perpendicular (80 ° to 90 ° so that the upper end of the upright plate 22a is inclined toward the wall surface W. °) is formed. Furthermore, the angle of the back surface portion of the accommodating portion 21 that faces the support plate holding portion 22 is also adjusted to be the same angle as the inclination angle θ of the upright plate 22a.

  And when installing the connector 1 mentioned above in the use field, first, the curing sheet 100 is inserted in the attachment base 11 of the support plate 10 from both directions. At this time, the edge of the inserted curing sheet 100 is sandwiched between the front-side sandwiching piece 14 and the rear-side sandwiching piece 13 of the mounting base 11, and the sheet 100 is held by the restoring force accompanying the deformation of the support auxiliary member 15. It is pressed to the front side holding piece 14 side. Next, laying of the curing sheet 100 is completed by inserting the support plate 10 in a state where the curing sheet 100 is inserted into the insertion recess 24 of the support base 20 installed on the floor surface F.

  Moreover, after completion | finish of the operation | work at a use site, the removal operation | work of the curing sheet 100 is completed by pulling out the curing sheet 100 from the support plate 10, and removing the support plate 10 from the support stand 20. FIG.

  As described above, in the curing sheet connector 1 described above, the width of the back-side sandwiching piece 13 facing the wall surface W extends a predetermined length longer than the width of the opposing front-side sandwiching piece 14. A pair of insertion recesses 12 whose distance between the front-side sandwiching piece 14 and the rear-side sandwiching piece 13 is set to be at least approximately equal to the thickness of the used curing sheet 100. The portion 12a is opened toward the insertion direction side of the curing sheet 100, and the abutting portion 12b when the curing sheet 100 is inserted is aligned with the abutting portion 12b of the other mounting base 11 back to back. Symmetrical arrangement.

  Thereby, when installing the curing sheet 100, fixing members, such as an adhesive tape and a magnet, become unnecessary, and the curing sheet 100 can be erected and held stably.

  Moreover, the edge of the contact surface with the curing sheet 100 in the back surface side holding piece 13 of the mounting base 11 is based on the width A between the front surface side holding piece 14 and the back surface side holding piece 13 in the insertion recess 12. Since the support auxiliary member 15 having a diameter B of at least approximately half of the width A to the same length is provided, the curing sheet 100 can be more securely clamped and fixed.

  Furthermore, since the shape of the support auxiliary member 15 is a long cylindrical shape, the retainability of the cured sheet 100 after insertion can be enhanced while providing easy removal and insertion of the cured sheet 100.

  Moreover, the back surface side clamping piece 13 of the insertion recessed part 12 is made into the shape which was gradually expanded and curved-opened from the contact | abutting surface side of the curing sheet 100 inserted to the opening part 12a, and the diameter of the support auxiliary member 15 was made into an insertion recessed part. When the curing sheet 100 is inserted into the mounting base 11, the restoring force due to the bending of the back-side holding piece 13 and the back-side holding piece 13 are reduced. The clamping and fixing of the curing sheet 100 can be realized reliably by using the restoring force of the provided support auxiliary member 15.
