Description

[Technical Field]

[0001] The present invention relates to a rod-shaped positioning member for positioning an object. [Background technology]

[0002] During the manufacturing process of a structure, it is sometimes necessary to position (hold) a component (object) that constitutes part of the structure in a predetermined position. In conventional technology, a long rod-shaped bolt or the like is screwed into the object to attach it, and the object is positioned (held) while floating or separated from a reference point. However, screwing a long rod-shaped bolt or the like into the object is time-consuming and labor-intensive. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0003] In view of the above problem, the present invention provides a positioning member that can be attached more quickly than conventional positioning members. [Means for solving the problem]

[0004] The positioning member of the present invention is a rod-shaped positioning member for positioning an object, characterized in that it has an upper end provided with a thread so as to screw into a part of the object, and a lower end not provided with a thread so as not to screw into a part of the object.

[0005] According to the above feature, it is possible to attach the device to an object more quickly than before.

[0006] The positioning member of the present invention is characterized in that the length of the lower end is longer than the length of the upper end.

[0007] According to the above feature, when the overall length of the positioning member is long, the time required for attaching the positioning member can be further reduced. [Effects of the Invention]

[0008] As described above, the positioning member of the present invention can be attached to an object more quickly than conventional positioning members. [Brief explanation of the drawings]

[0010] 200 Positioning member 221 thread 210 Lower end 220 Upper end DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the shapes of the drawings referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily correspond to the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios in the drawings.

[0012] First, Fig. 1 shows a structure 900 that is the target of the repair method of the present invention. Fig. 1 is a perspective view of the installation site where the structure 900 is installed, Fig. 2(a) is a perspective view of the installation site where the structure 900 is installed, Fig. 2(b) is a side view of the installation site where the structure 900 is installed, Fig. 3(a) is a perspective view of the installation site where the structure 900 is installed, and Fig. 3(b) is a side view of the installation site where the structure 900 is installed.

[0013] As shown in FIG. 1 , structure 900 is a concrete roadside gutter buried in the shoulder of road surface R. It has a roughly rectangular parallelepiped shape with a bottom wall 910, side walls 920 on both sides, and a top wall 930, and includes a water collection space 940 inside. Water collection holes 950 are provided in the top wall 930, which run through in the vertical direction. Because water collection holes 950 communicate with water collection space 940, rainwater and the like flowing from the road surface R can be drained into water collection space 940. Furthermore, upper end portions 931 of the top wall 930, located on both sides of the water collection holes 950, gradually receive damage X (such as cracks and peeling of the concrete) due to the load exerted by people and vehicles passing through and deterioration over time. In this embodiment, a curbstone Y is placed above one of the upper end portions 931. Furthermore, although the structure 900 is a concrete gutter, it is not limited to this and may be any structure made of any material as long as it has a water collection space 940 and a water collection hole 950. For example, the structure 900 may be any structure other than a gutter, such as a water collection basin. Furthermore, although the water collection space 940 has a circular cross section, it is not limited to this and may have any shape, such as a rectangular cross section.

[0014] 2 and 3, when repairing the structure 900 in the present invention, first, only the upper end portion 931 on one side (the side where the curbstone Y is not placed) is removed to form an opening P1. Specifically, as shown in FIG. 2, a hole P2 extending vertically in the up-down direction to a position where it contacts the inner surface 941 of the water collection space 940 is made in the upper end portion 931 on one side using a drill or the like. This makes the bottom P3 of the hole P2 continuous with the inner surface 941 of the water collection space 940. Then, the upper end portion 931 is cut with a cutting tool such as an electric cutter along a cutting plane P4 that passes through the hole P2 and extends vertically in the up-down direction, and is separated from the side wall 920. This forms an opening P1 on one side of the upper wall 930 of the structure 900, as shown in FIG. In this embodiment, a curbstone Y is placed above the upper end portion 931 on one side, and therefore the upper end portion 931 on the side where the curbstone Y is not placed is removed. However, this is not limited to this, and if no curbstone Y is installed, either one of the upper end portions 931 on both sides can be removed. Furthermore, in this embodiment, a hole P2 is provided, but this is not limited to this, and the upper end portion 931 may be cut along the cutting plane P4 with a cutting tool such as an electric cutter without providing the hole P2. Furthermore, the present invention is a simple method in which a hole P2 extending toward the water collection space 940 is provided in one upper end portion 931, and the upper end portion 931 is cut along the cutting plane P4 that contacts the water collection space 940. Therefore, there is no need for a special cutting device as in the prior art, and this method can be implemented with a general electric drill, electric cutter, or the like.

[0015] Next, Fig. 4 shows a water collection space forming body 100 used when repairing a structure 900 by the repair method of the present invention. Fig. 4(a) is an overall perspective view of the water collection space forming body 100, and Fig. 4(b) is a side view of the water collection space forming body 100.

[0016] As shown in Fig. 4, the water collecting space forming body 100 is a semicircular metal member, and a first forming body 110 and a second forming body 120, which are separate members, are connected by a connecting portion 130. Specifically, the arc-shaped first forming body 110 and the arc-shaped second forming body 120 are prepared separately, and with an end portion 111 of the first forming body 110 and an end portion 121 of the second forming body 120 separated from each other, plate-shaped metal connecting portions 130 are welded and fixed to the end portion 111 of the first forming body 110 and the end portion 121 of the second forming body 120, respectively, thereby connecting and fixing the first forming body 110 and the second forming body 120. In addition, because the connecting portions 130 are arranged intermittently, water collecting portions 140 in the form of holes that penetrate vertically are formed between the connecting portions 130. The connecting portion 130 is provided with an insertion hole 131 through which a positioning member 200 (described later) is inserted, and a nut portion 132 that is arranged to overlap the insertion hole 131 and screws the positioning member 200. An attachment portion 101 in the form of a nut for attaching a fixing member (described later) is fixed to the outer surface of the second forming body 120. An attachment assisting portion 102 is provided on the outer surface of the second forming body 120 to facilitate attachment of a repair material (described later).

[0017] The water collection space forming body 100 is provided with a first forming body 110 and a second forming body 120, which are separate members, on either side of the water collection section 140. Therefore, even if the shape of the inner surface 941 of the water collection space 940 of the structure 900 or the position of the water collection holes 950 is changed, by changing the shapes of the first forming body 110 and the second forming body 120 of the water collection space forming body 100, the water collection space forming body 100 can be easily brought into close contact with the shape of the inner surface 941 of the water collection space 940 of the structure 900. The water collection space forming body 100 is provided with two forming bodies, the first forming body 110 and the second forming body 120, but may be provided with three or more forming bodies. Furthermore, the water collecting space forming body 100 is composed of two forming bodies, the first forming body 110 and the second forming body 120, but is not limited to this, and the water collecting space forming body 100 may be composed of a single plate material, and a through hole may be formed in the plate material to serve as the water collecting section 140. However, if distortion or the like occurs in the plate material when forming the through hole, by configuring the water collecting section 140 between the two forming bodies, the first forming body 110 and the second forming body 120, no through hole will be formed in the plate material, and therefore distortion can be prevented.

[0018] Next, Fig. 5 shows a positioning member 200 used when repairing a structure 900 by the repair method of the present invention. Fig. 5 is an overall perspective view of the positioning member 200.

[0019] As shown in Fig. 5, the positioning member 200 is a rod-shaped member made of metal and configured to be insertable into a threaded hole of a nut or the like. The positioning member 200 has a lower end 210 that is not threaded so as not to thread into the threaded hole, and an upper end 220 that is threaded with a thread 221 so that it can thread into the threaded hole. A hexagonal head 222 is provided at the top of the upper end 220, and a fastening tool or the like can be connected to the head 222 to rotate and connect the positioning member 200 to an object such as a nut like a bolt. The length L1 of the lower end 210 is longer than the length L2 of the upper end 220 on which the thread 221 is provided. Although the length L1 of the lower end portion 210 is longer than the length L2 of the upper end portion 220, the present invention is not limited thereto. The length L1 of the lower end portion 210 and the length L2 of the upper end portion 220 may each be any length. For example, the length L1 of the lower end portion 210 may be shorter than the length L2 of the upper end portion 220, or the length L1 of the lower end portion 210 may be equal to the length L2 of the upper end portion 220. Furthermore, as will be described later, the positioning member 200 is attached to the water-collecting space-forming body 100 as an object to be positioned. However, the present invention is not limited thereto. The positioning member 200 can be attached to any object to be positioned. The object to be positioned has a screw hole into which the upper end portion 220, which has a screw thread 221, can be threaded. Furthermore, the positioning member 200 is configured so that the tip 211 of the lower end portion 210 can abut against a location that serves as a reference for positioning in order to support the object to be positioned.

[0020] Next, Fig. 6 shows a state in which a water-collecting space-forming body 100 has been attached to a structure 900 by the repair method and manufacturing method of the present invention. Fig. 6(a) is an overall perspective view of the structure 900, and Fig. 6(b) is a side view of the structure 900.

[0021] As shown in FIG. 6 , the water collection space forming body 100 is inserted into the water collection space 940 from above the water collection space 940 through the opening P1 formed in the structure 900. Then, the position of the water collection space forming body 100 is adjusted so that the outer surface 119 of the first formation body 110 of the water collection space forming body 100 abuts against the upper inner surface 941 (the side of the upper end portion 931 that is not cut off) of the water collection space 940. Specifically, the lower end portion 210 of the positioning member 200 is inserted through the nut portion 132 and the insertion hole 131 of the water collection space forming body 100. Then, the upper end portion 220 of the positioning member 200 is screwed into the nut portion 132, and the positioning member 200 is rotated until the tip 211 of the lower end portion 210 abuts against the bottom portion 949 of the water collection space 940. Then, the positioning member 200 can easily position the water collection space forming body 100 in a state where the water collection space forming body 100 is floating above the bottom 949 of the water collection space 940 so that the water collection space forming body 100 is in close contact with the inner surface 941 of the water collection space 940 .

[0022] Furthermore, when the positioning member 200 is rotated and the upper end portion 220 of the positioning member 200 is tightly fastened to the nut portion 132, the tip 211 of the lower end portion 210 of the positioning member 200 comes into stronger contact with the bottom portion 949 of the water collection space 940, pushing the entire water collection space forming body 100 upward. As a result, the outer surface 119 of the first formation body 110 of the water collection space forming body 100 comes into strong contact with the inner surface 941 of the water collection space 940, and the end 128 of the second formation body 120 of the water collection space forming body 100 comes into strong contact with the inner surface 941 of the water collection space 940. Note that adhesive or the like may be applied to the outer surface 119 of the first formation body 110 and the end 128 of the second formation body 120 to improve adhesion.

[0023] The positioning member 200 is used to position the water collection space forming body 100, but there are cases where the desired position where the water collection space forming body 100 is positioned (in FIG. 6, the water collection space forming body 100 is positioned above the water collection space 940) is far away from the position that serves as the reference for positioning (in FIG. 6, the water collection space forming body 100 is positioned at the bottom 949 below the water collection space 940). In this case, the overall length of the positioning member 200 becomes long, which may take time to attach the positioning member 200 by screwing it into the nut portion 132. However, in the positioning member 200 of the present invention, the lower end portion 210 side of the positioning member 200 does not have a thread 221, so there is no need to screw the lower end portion 210 side of the positioning member 200 into the nut portion 132, and the lower end portion 210 side of the positioning member 200 can be quickly inserted into the nut portion 132. Then, attachment of the positioning member 200 can be completed quickly by simply screwing the upper end 220 side of the positioning member 200 into the nut portion 132. In particular, since the length L1 of the lower end 210 is longer than the length L2 of the upper end 220, the attachment work time of the positioning member 200 can be further reduced when the overall length of the positioning member 200 is long. Note that the positioning member 200 of the present invention is used to position the water-collecting space-forming body 100 as an object, but is not limited to this, and can be attached to any object for the purpose of positioning (holding) the object in a state where it is floating or separated from a reference point.

[0024] Next, Fig. 7 shows a water collection hole forming body 300 used when repairing a structure 900 by the repair method of the present invention. Fig. 7(a) is an overall perspective view of the water collection hole forming body 300, and Fig. 7(b) is a plan view of the water collection hole forming body 300.

[0025] As shown in FIG. 7 , the water collection hole forming body 300 is made of metal and has a roughly rectangular parallelepiped shape, and is composed of two parallel side plates 310 and a connecting plate 320 that connects the side plates 310. A water collection hole 330 is formed between the opposing side plates 310, and as will be described later, the water collection hole 330 can be overlapped vertically and communicate with the water collection section 140 of the water collection space forming body 100. In addition, a fixing device 340 that protrudes laterally is provided on the side plate 310. This fixing device 340 is composed of a nut portion 341 fixed to the side plate 310 and a bolt portion 342 that screws into the nut portion 341. By rotating the bolt portion 342, the bolt portion 342 can move laterally relative to the nut portion 341. Although the water collection hole forming body 300 is configured in a frame shape with side plates 310 and connecting plates 320, it is not limited to this and may have any configuration as long as it is capable of collecting rainwater, etc. and is capable of communicating with the water collection section 140 of the water collection space forming body 100.

[0026] Next, Figures 8 and 9 show the state in which a water collection hole forming body 300 has been attached to a water collection space forming body 100 by the repair method and manufacturing method of the present invention. Note that Figure 8(a) is an overall perspective view of the structure 900, Figure 8(b) is a side view of the structure 900, Figure 9(a) is an overall perspective view of the structure 900, and Figure 9(b) is a side view of the structure 900.

[0027] As shown in FIG. 8, the water collection hole forming body 300 is placed on the water collection space forming body 100 via the open portion P1. At this time, the water collection hole forming body 300 is placed on the water collection space forming body 100 from above the positioning members 200 (positioning members 200 located at both ends in FIGS. 8 and 9) already attached to the water collection space forming body 100 so that the water collection holes 330 of the water collection hole forming body 300 are inserted, so the positioning members 200 do not get in the way. In this state, as shown in FIGS. 8(a) and 9(a), another positioning member 200 (the central positioning member 200) is attached to the nut portion 132 and the insertion hole 131 of the water collection space forming body 100 via the water collection holes 330 of the water collection hole forming body 300. A fixing plate 290, through which the upper end portion 220 is inserted, and a nut 280 adjacent to the fixing plate 290 are provided on the upper end portion 220 of the positioning member 200. Therefore, when the positioning member 200 is attached to the water collection space forming body 100, if the nut 280 is tightened with the fixing plate 290 in contact with the connecting plate 320 of the water collection hole forming body 300, the fixing plate 290 will press down on the water collection hole forming body 300 from above, and the water collection hole forming body 300 will be fixed so as not to shift relative to the water collection space forming body 100. Note that the water collection holes 330 of the water collection hole forming body 300 and the water collection section 140 of the water collection space forming body 100 are stacked vertically, so rainwater etc. collected from the water collection holes 330 can be drained into the water collection space 940 via the water collection section 140.

[0028] Next, as shown in Fig. 9, the bolt portion 342 of the fixing device 340 of the water collection hole formation body 300 is rotated so that the head of the bolt portion 342 abuts against the exposed inner surface of the side wall 920. Then, the water collection hole formation body 300 is fixed by the fixing device 340 so that it does not shift sideways. Note that the fixing device 340 is composed of a nut portion 341 and a bolt portion 342, but is not limited to this and may have any configuration as long as it can fix the water collection hole formation body 300 so that it does not shift sideways.

[0029] Furthermore, a fixing member 500 is attached to an attachment portion 101 provided on the water collection space forming body 100. The fixing member 500 is in the form of a bolt and can be attached by screwing it into the attachment portion 101 which is in the form of a nut. By rotating the fixing member 500, a part of the fixing member 500 (for example, the tip 510) moves toward the side wall 920 and engages with a part of the side wall 920 (for example, the bottom P3). Then, the fixing member 500 fixes the water collection space forming body 100 so that it does not fall off downward. Note that the fixing member 500 is in the form of a bolt, but is not limited to this, and any configuration may be used as long as the fixing member 500 can be fixed to the water collection space forming body 100 and a part of the fixing member 500 can be engaged with a part of the side wall 920. Furthermore, the bottom P3 of the hole P2 in the side wall 920 is used as the location where a portion of the fixing member 500 is engaged, but this is not limited to this, and a location (hole or recess) where a portion of the fixing member 500 can be engaged may be formed at any position on the inner surface of the side wall 920.

[0030] Next, Fig. 10 shows an embodiment of repair using concrete or the like according to the repair method of the present invention. Fig. 10(a) is an overall perspective view of a structure 900, and Fig. 10(b) is a side view of the structure 900.

[0031] As shown in Figure 10, the open portion P1 is surrounded by the water collection space forming body 100, the water collection hole forming body 300, and the side wall 920. Then, a repair material Z such as concrete or mortar (a quick-drying material is preferable) is poured into this surrounded space. After the repair material Z has hardened, the positioning member 200 is removed, completing the repair of the structure 900 and completing the repaired structure 900. In this way, according to the structure repair method and structure manufacturing method of the present invention, the open portion P1 is formed by cutting out only the upper end portion 931 on one side, and the water collection space forming body 100 and the water collection hole forming body 300 are positioned using this open portion P1, and the repair material Z is poured in, which is a simple method that allows the repair and manufacturing of the structure 900 to be carried out quickly.

[0032] On the side where the opening P1 is not formed (the curb Y side), repair material Z is poured between the upper end 931 and the water collection hole forming body 300 for repair. Furthermore, if the side wall 920 is also removed along with the upper end 931 when forming the opening P1, a side plate or the like may be attached and used in place of the side wall 920, or the side surface of the road surface may be used to pour repair material Z into the space surrounded by the water collection space forming body 100, the water collection hole forming body 300, and the side plate (the side surface of the road surface). Furthermore, the structure repair method and structure manufacturing method of the present invention are not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included within the scope of their rights.
