Description

[Technical field]

[0001] The present invention relates to a fastener for temporary enclosure boards used to enclose construction sites, material storage areas, etc., for fastening various panels such as soundproofing panels, privacy panels, and vibration-damping panels to the temporary enclosure boards. [Background technology]

[0002] Conventionally, in order to secure soundproofing panels to each temporary fencing board surrounding a construction site, a material storage yard, etc., for example, as shown in Figures 13 and 14, temporary fencing board fasteners in the form of horizontally elongated fastening plates 23 are pressed against the top and bottom of each of two soundproofing panels 22 placed along the top and bottom halves of the back surface of a temporary fencing board 21, and both ends of these fastening plates 23 are secured with screws 26 into screw holes (not shown) provided in the bent portions 25 of both side bodies 24 of the temporary fencing board 21 (Patent Document 1).

[0003] In this manner, the two soundproof panels 22 are attached to the top and bottom of the rear surface of the temporary enclosure 21 while being held down by the retaining plates 23, respectively.

[0004] As another example of this type of temporary fencing fixture, as shown in Fig. 15, there is one in which a suction-cup-shaped elastic pressing body 32 is fixed to the center of a pressing plate 31 made of a horizontally elongated elastic body. As shown in Figs. 16 and 17, this temporary fencing fixture presses a privacy panel 34 placed along the back surface of a temporary fencing 33 with the elastic pressing body 32, and both ends 31a of the pressing plate 31 fit inside bent portions 35 formed on both side ends of the temporary fencing 33, so that both ends 31a of the pressing plate 31 engage with the bent portions 35 while applying elastic force (Patent Document 2).

[0005] Such a temporary enclosure fastener makes it possible to easily fasten the privacy panel 34 to the temporary enclosure 33 without having to have tools ready at all times. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-108764 A [Patent Document 2] Utility Model Registration No. 3232105 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the temporary fencing fixture described in Patent Document 1, the fastener plate 23 is simply pressed against the soundproof panel 22 that is aligned with the back surface of the temporary fencing 21, so unless the soundproof panel 22 is approximately equal in thickness to the depth of the side body 24 of the temporary fencing 21 or slightly thicker, the soundproof panel 22 cannot be pressed against the temporary fencing 21 in a pressed state. If the soundproof panel 22 is thinner than the depth of the side body 24 of the temporary fencing 21, the soundproof panel 22 is not pressed down, and the soundproof panel 22 will slip off the temporary fencing 21, which is a problem.

[0008] In addition, the temporary fencing fastener described in Patent Document 2 is designed to press a privacy panel 34 aligned along the back surface of a temporary fencing 33 at a single point with an elastic pressure body 32 fixed to the center of a pressure plate 31. As a result, the pressing area of ​​the privacy panel 34 by the elastic pressure body 32 is small, making it difficult to ensure sufficient pressing force, and there is a problem that the privacy panel 34 may slip off the temporary fencing 33.

[0009] Furthermore, since it is difficult to ensure sufficient pressing force with the temporary fencing fastener described in Patent Document 2, an adhesive may be applied to the surface of the privacy panel 34 that is to be placed against the back surface of the temporary fencing 33, and the adhesive-coated surface of the privacy panel 34 may be adhered to the temporary fencing 33 before use.However, this has the problem that if the adhesive applied to the privacy panel 34 gets wet from rain or its adhesive strength is reduced or lost due to temperature differences between summer and winter, etc., there is a risk that the privacy panel 34 will slip off the temporary fencing 31.

[0010] Therefore, the present invention has been made to solve the conventional problems and aims to provide a fastener for temporary fencing that does not reduce the pressing force on various panels such as soundproofing panels, privacy panels, and vibration-damping panels regardless of the thickness of these panels, and that has a large pressing area for these panels to ensure sufficient pressing force, thereby preventing these panels from slipping off the temporary fencing. [Means for solving the problem]

[0011] The temporary fencing fastener of the present invention presses a pressing portion 2 provided at one end of a pressure plate 1 made of a horizontally elongated elastic body against one first side body 13a of a temporary fencing board 11 and an end of a panel 3 aligned along the back surface of the temporary fencing board 11, and presses the other end of the pressure plate 1 against a second side body 13b formed rearward of the other first side body 13a of the temporary fencing board 11, so that the pressure plate 1 is warped from a state in which it is warped away from the panel 3 to a state in which it is warped in a direction toward the panel 3.

[0012] The temporary fencing fastener of the present invention presses a pressing portion 2 provided at one end of a pressure plate 1 made of a horizontally elongated elastic body against one first side body 13a of the temporary fencing 11 and the end of a panel 3 aligned along the back surface of the temporary fencing 11, and fastens one end of a retaining plate 4 having a dogleg-shaped longitudinal section to the other end of the pressure plate 1, and presses the other end of the retaining plate 4 and the other end of the pressure plate 1 against a second side body 13b formed rearward of the other first side body 13a of the temporary fencing 11, so that the pressure plate 1 is warped from a state in which it is warped away from the panel 3 to a state in which it is warped in a direction toward the panel 3.

[0013] Furthermore, in the temporary fencing fixture of the present invention, the fastening plate 4 has a screw through hole 4a at one end, and a set screw 5 is screwed through this screw through hole 4a into a screw hole 1a provided near the other end of the pressure plate 1, so that the plate can be fastened to the pressure plate 1, and the screw end 5a of the set screw 5 is pressed against the panel 3 placed along the back surface of the temporary fencing plate 11. Effect of the Invention

[0014] When the pressure plate 1 of the temporary fencing fastener of the present invention is bent so that it is in contact with the panel 3 placed along the back surface of the temporary fencing 11, most of the surface of the pressure plate 1 presses against the panel 3 placed along the back surface of the temporary fencing 11, thereby increasing the pressing area and ensuring sufficient pressing force, preventing the panel 3 from slipping off the temporary fencing 11.

[0015] Furthermore, in the temporary fencing fastener of the present invention, when the other end of the retaining plate 4 and the other end of the pressure plate 1 are pressed against the second side body 13b of the temporary fencing 11, the temporary fencing board is even less likely to come off the temporary fencing board 11 even due to impact, vibration, etc.

[0016] Furthermore, in the temporary fencing fastener of the present invention, the threaded end 5a of the fixing screw 5 is pressed against the panel 3 placed along the back surface of the temporary fencing 11, so that the threaded end 5a of the fixing screw 5 also presses against the portions not pressed by the pressure plate 1, thereby exerting a more sufficient pressing force.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the temporary enclosure fastener of the present invention will be described in detail with reference to the drawings.

[0019] 1 to 6 show one embodiment of a temporary enclosure fastener of the present invention, and FIGS. 7 to 12 show other embodiments of a temporary enclosure fastener of the present invention.

[0020] In the embodiment shown in Figures 1 to 6, the temporary enclosure fastener of the present invention presses a pressing portion 2 provided at one end of a pressing plate 1 made of a horizontally elongated elastic body against one first side body 13a of a temporary enclosure 11 and an end of a panel 3 aligned along the back surface of the temporary enclosure 11, and presses the other end of the pressing plate 1 against a second side body 13b formed behind the other first side body 13a of the temporary enclosure 11. The pressing plate 1 is then warped from a state in which it is warped away from the panel 3 as shown by the imaginary line in Figure 5 to a state in which it is warped in a direction in contact with the panel 3 as shown by the solid line in Figure 5.

[0021] In the embodiment shown in Fig. 7 to 12, the temporary enclosure fastener of the present invention presses a pressing portion 2 provided at one end of a pressing plate 1 made of a horizontally elongated elastic body against one first side body 13a of the temporary enclosure 11 and an end of a panel 3 aligned along the back surface of the temporary enclosure 11, and fastens one end of a retaining plate 4 having a dogleg-shaped vertical section to the other end of the pressing plate 1, and presses the other end of the retaining plate 4 and the other end of the pressing plate 1 against a second side body 13b formed behind the other first side body 13a of the temporary enclosure 11. The pressing plate 1 is then warped from a state in which it is warped away from the panel 3 as shown by the imaginary line in Fig. 11 to a state in which it is warped in a direction in contact with the panel 3 as shown by the solid line in Fig. 11.

[0022] The pressure plate 1 is made of an elastic body formed of a horizontally elongated steel plate or the like, which is slightly longer than the distance between the first side body 13a on one side and the second side body 13b on the other side of the temporary fencing board 11 described later. The distance is generally about 50 cm, so the length of the pressure plate 1 is made about 1 cm longer than this length, so that the pressing portion 2 at one end of the pressure plate 1 and the other end of the pressure plate 1 can be pressed against the first side body 13a and the second side body 13b of the temporary fencing board 11 so that the pressure plate 1 changes from the state in which it is warped in the direction away from the panel 3 placed along the back surface of the temporary fencing board 11 as described above to the state in which it is warped in the direction in contact with the panel 3 placed along the back surface of the temporary fencing board 11. In addition, when the pressing plate 1 is bent in a direction in which it contacts the panel 3 aligned along the back surface of the temporary enclosure 11, only the other end of the pressing plate 1 without the pressing portion 2 is to be in contact with the second side body 13b, but it is preferable that this other end is to be in contact with the second side body 13b and the part slightly forward of the other end is to be in contact with the back surface of the outer end 15 of the first side body 13a described later. In addition, the width of the pressing body 1 is about 3 to 5 cm in the illustrated example, but it may be appropriately set depending on the pressing condition when the pressing portion 2 at one end of the pressing body 1 and the other end of the pressing body 1 are pressed against the first side body 13a and the second side body 13b of the temporary enclosure 11 described later, the contact area with the panel 3, etc. Furthermore, the elastic force of the pressing plate 1 may be appropriately set depending on the fastening condition of the panel 3 aligned along the back surface of the temporary enclosure 11 described later, the thickness, weight, etc. of the panel 3.

[0023] The pressing portion 2 at one end of the pressing plate 1 is pressed against one of the first side bodies 13a of the temporary enclosure 11 and the end of the panel 3 aligned along the back surface of the temporary enclosure 11, and in the illustrated example, it is folded back toward the front surface 1b side of the pressing plate 1, but it may be a separate member fixed to the front surface 1b side. The folded width of the pressing portion 2 is about 5 to 14 mm, which is obtained by subtracting about 1 to 10 mm from the depth of the first side body 13a of the temporary enclosure 11 described later, which is about 15 mm, and is positioned so that it is pressed against the first side body 13a of the temporary enclosure 11 and the end of the panel 3 described later so as not to move.

[0024] The retaining plate 4 has a screw through hole 4a at one end, and a set screw 5 is screwed from this screw through hole 4a into a screw hole 1a provided near the other end of the pressure plate 1 to secure it to the pressure plate 1, and the screw end 5a of the set screw 5 is pressed against the panel 3 aligned along the back surface of the temporary fencing board 11, as shown in Figures 11 and 12. The other end of the retaining plate 4 is pressed against the second side body 13b of the temporary fencing board 11, or against the back surface of the outer end 18 of the second side body 13b described later, making it difficult for the retaining plate 4 to come off from the second side body 13b.

[0025] The temporary enclosure 11 is made of iron, steel, aluminum alloy, etc., and has side bodies 13 at both ends of the plate body 12. As shown in Figures 6 and 12, these side bodies 13 are formed by bending both ends 14 of the plate body 12 at a right angle to the back side to form a first side body 13a, bending the outer end 15 of one of the first side bodies 13a inwardly in a roughly L-shape, forming a second side body 13b behind the first side body 13a, forming a concave groove 16 between them, and bending the outer end 15 of the other first side body 13a outwardly in a roughly L-shape, forming a second side body 13b behind the first side body 13a, forming a convex groove 17 between them. The depth of the first side body 13a and the second side body 13b is generally about 15 mm. Here, the rear of the first side body 13a means the direction from the front surface of the temporary surrounding board 11 toward the back surface thereof, and refers to the downward direction in Figs.

[0026] When the side bodies 13 of adjacent temporary surrounding boards 11 are butted together during use, the concave grooves 16 and the convex grooves 17 fit together to facilitate positioning. Additionally, the outer ends 18 of the second side bodies 13b of the side bodies 13 are each formed with a reinforcing body 19 that is bent inwardly into a roughly L-shape. Furthermore, the upper, middle and lower parts of the side body 13 are provided with through holes (not shown) for wires that connect the side bodies 13 of adjacent temporary surrounding boards 11 when they are butted together, as necessary.

[0027] The panel 3 may be a privacy panel, a soundproof panel, a vibration-damping panel, etc., and may be a plate-like or sheet-like body made of wood, synthetic resin, light metal, concrete, etc., as long as it can be fitted along the back surface of the temporary enclosure 11. The panel 3 may have a height and width that can be fitted along the back surface of the temporary enclosure 11, since the temporary enclosure 11 generally has a height of about 300 cm and a width of about 50 cm. The thickness of the panel 3 may be thinner than the depth of the first side body 13a of the temporary enclosure 11, and is preferably about 1 / 10 to 1 / 2 of the depth. Since the general depth of the temporary enclosure 11 is about 15 mm, the thickness of the panel 3 is preferably about 1.5 to 7.5 mm, and more preferably about 2 to 5 mm.

[0028] 1 to 6, in order to fasten various panels such as soundproof panels, privacy panels, and vibration-damping panels to a temporary enclosure, the temporary enclosure 11 is first laid down with its back surface facing up, and the panel 3 is aligned along its back surface. In this case, an adhesive can be applied to the surface of the panel 3 that is aligned along the back surface of the temporary enclosure 11, if necessary.

[0029] Next, at the top, middle, and bottom of the temporary fencing board 11, the folded end of the pressing portion 2 at one end of the pressure plate 1 of the temporary fencing board fastener of the present invention is faced toward the panel 3, and this pressing portion 2 is pressed against one of the first side bodies 13a of the temporary fencing board 11 and the end of the panel 3 to position it so as not to move. Note that in this embodiment, the temporary fencing board fastener of the present invention is used in three positions at the top, middle, and bottom of the temporary fencing board 11, but it can also be used in other positions depending on how well the panel 3 is fastened and the shape, thickness, weight, etc. of the panel 3.

[0030] Then, the pressure plate 1 is bent in a direction away from the panel 3 placed along the back surface of the temporary enclosure board 11, and the other end of the pressure plate 1 is pressed against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11, resulting in the state shown by the phantom line in Figure 5.

[0031] Therefore, when the middle part of the pressure plate 1 is pressed against the panel 3 placed along the back surface of the temporary enclosure 11 and is warped in the direction of contact with the panel 3, it will be in the state shown by the solid line in FIG.

[0032] In this case, it is sufficient to simply press the other end of the pressure plate 1 against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11, but as shown in Figures 5 and 6, if the other end of the pressure plate 1 is pressed against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11 and a portion of the pressure plate 1 slightly in front of the other end is pressed against the back surface of the outer end 15 of the first side body 13a, the pressure plate 1 will come closer to the panel 3 aligned along the back surface of the temporary enclosure board 11.

[0033] Therefore, in the state shown by the solid line in Figure 5, most of the surface of the pressure plate 1, except for the area near the other end of the pressure plate 1, presses the panel 3 placed along the back surface of the temporary enclosure board 11, thereby increasing the pressing area and ensuring sufficient pressing force, preventing the panel 3 from slipping off the temporary enclosure board 11.

[0034] 7 to 12, in order to fasten various panels such as soundproof panels, privacy panels, and vibration-damping panels to a temporary enclosure, the temporary enclosure 11 is laid down with its back surface facing up, as in the above-described embodiment, and the panel 3 is aligned along its back surface. In this case as well, an adhesive can be applied to the surface of the panel 3 that is aligned along the back surface of the temporary enclosure 11, if necessary.

[0035] Next, at the top, middle and bottom of the temporary fencing board 11, the folded end of the pressing portion 2 at one end of the pressure plate 1 of the temporary fencing board fastener of the present invention is faced towards the panel 3, and this pressing portion 2 is pressed against one of the first side bodies 13a of the temporary fencing board 11 and the end of the panel 3 to position it so as not to move. Note that even in this embodiment, the temporary fencing board fastener of the present invention can also be used in other positions on the temporary fencing board 11 depending on the degree of fastening of the panel 3 and the shape, thickness, weight, etc. of the panel 3.

[0036] Then, the pressure plate 1 is bent in a direction away from the panel 3 placed along the back surface of the temporary enclosure board 11, and the other end of the pressure plate 1 is pressed against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11, resulting in the state shown by the phantom line in Figure 11.

[0037] Therefore, the middle part of the pressure plate 1 is pressed towards the panel 3 placed along the back surface of the temporary enclosure 11, and is warped in the direction of contact with the panel 3. Then, one end of a retaining plate 4 is temporarily fixed near the other end of the pressure plate 1 with a set screw 5, the other end of this retaining plate 4 is pressed against the second side body 13b, and the set screw 5 is screwed in to secure the pressure plate 1, and the screw end 5a of the set screw 5 is pressed against the panel 3 placed along the back surface of the temporary enclosure 11, resulting in the state shown by the solid line in Figure 11.

[0038] In this case, as shown in Figure 11, the other end of the retaining plate 4 is pressed against the back surface of the outer end 18 of the second side body 13b of the temporary fencing board 11, making it difficult to come off from this second side body 13b.Therefore, the pressure plate 1 is firmly fixed to the temporary fencing board 11 together with the retaining plate 4, and the threaded end 5a of the retaining screw 5 is pressed against the panel 3, so that even if the panel 3 is a vibration-damping panel, it will not come off from the temporary fencing board 11 due to strong impact or vibration.

[0039] In this case, it is also possible to simply press the other end of the pressure plate 1 against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11, but as shown in Figures 11 and 12, if the other end of the pressure plate 1 is pressed against the second side body 13b formed rearward of the other first side body 13a of the temporary enclosure board 11 and a portion of the pressure plate 1 slightly in front of the other end is pressed against the back surface of the outer end 15 of the first side body 13a, the pressure plate 1 will come closer to the panel 3 aligned along the back surface of the temporary enclosure board 11.

[0040] Therefore, in the state shown by the solid line in Figure 11, most of the surface of the pressure plate 1, except for the area near the other end of the pressure plate 1, presses the panel 3 placed along the back surface of the temporary enclosure board 11, thereby increasing the pressing area and ensuring sufficient pressing force, preventing the panel 3 from slipping off the temporary enclosure board 11.

[0041] Then, by preparing a large number of such temporary fencing boards 11 and standing each of them as shown in Figures 2 and 8, butting the side bodies 13 of adjacent temporary fencing boards 11 together, fitting the concave grooves 16 and convex grooves 17 formed in the side bodies 13 into concave and convex engagements, and passing wire through the through holes of adjacent temporary fencing boards 11 to connect adjacent temporary fencing boards 11, a construction site, material storage area, etc. can be enclosed using such temporary fencing boards 11.
