[0011] [First embodiment] Hereinafter, one embodiment of the present invention will be described. 1, the construction jig 1 of this embodiment is used to assist in construction of a long cover 90. Specifically, the construction jig 1 is used to assist in processing operations such as cutting, drilling, or marking cutting and drilling positions on the cover 90.

[0012] 3 will be described as the front-to-back direction of the construction jig 1, the left-to-right direction of the paper will be described as the left-to-right direction of the construction jig 1, and the up-to-down direction of the paper will be described as the up-to-down direction of the construction jig 1. Therefore, in drawings other than FIG. 3, the directions on the paper may not match the directions indicated in the following description. The front-to-back direction of the construction jig 1 may also be referred to as the axial direction L1 (see FIG. 1).

[0013] As shown in FIG. 1 , the cover 90 includes a half-tubular (half-cylindrical in this embodiment) cover body 91 that covers a piping member, and cover flanges 92 extending from both edges of the cover body 91. The cover 90 is formed from a weather-resistant hard resin material and can be processed using tools such as cutting tools such as saws and drills. The cover 90 is intended to cover piping members such as pipes and joints for hot and cold water supply that are fixed to a wall surface (construction surface) of a house, for example. The cover 90 is, for example, 2 m long when shipped, and is cut to the appropriate length to fit the pipe, etc., at the construction site, and is fixed to the wall surface so as to cover the pipe, etc.

[0014] Next, we will explain the construction jig 1. The construction jig 1 is formed by injection molding using a resin material such as polypropylene or ABS resin, and is used by being placed over the cover 90 in order to process the cover 90.

[0015] 1 and 2, the construction jig 1 has a half-tubular shape (half-cylindrical shape in this embodiment) and includes a jig body 10 that covers a cover body 91, and jig flanges 20 that are formed on both edges of the jig body 10 and can abut against the surface of a cover flange 92. Furthermore, the construction jig 1 includes a cutting position guide 30, a first drilling position guide 40, and a second drilling position guide 50. These guides 30, 40, and 50 assist in the processing of the cover 90.

[0016] The jig body 10 has a shape corresponding to the cover body 91. The outer peripheral surface 10a of the jig body 10 has a shape that follows the outer peripheral surface 91a of the cover body 91 as a whole. In addition, as shown in Fig. 2, the inner peripheral surface 10b of the jig body 10 has a shape that follows the outer peripheral surface 91a of the cover body 91, and is a smooth curved surface without any irregularities.

[0017] As shown in Figures 1 and 5 to 7, the upper wall 11 of the jig body 10 is provided with a ring-shaped connecting portion 12 for connecting a connecting device such as a carabiner. A recess 12a is formed in the center of the connecting portion 12. During injection molding of the construction jig 1, a gate is positioned in the recess 12a, and a gate mark is formed in the recess 12a. A thick portion 13 is provided in the upper wall 11 of the jig body 10 in the front-to-rear direction of the connecting portion 12, and a through hole 14 is formed in a position corresponding to the connecting portion 12. This through hole 14 is a hole through which a mold for forming the connecting portion 12 passes during injection molding of the construction jig 1.

[0018] The two side wall portions 15 of the jig body 10 are provided with thick portions 16. The side surface 16a of one thick portion 16 and the side surface 16a of the other thick portion 16 extend substantially parallel to each other. A rib 17 is formed at the rear end of the jig body 10, extending outward from the jig body 10 in a direction perpendicular to the axial direction L1 of the jig body 10.

[0019] Both side surfaces of the jig flange 20 have a smooth uneven shape. Furthermore, both side surfaces of the jig flange 20 (specifically, at the apexes of the convex portions of the uneven shape) are formed with a plurality of vertically extending protrusions 21 that function as anti-slip surfaces when the jig flange 20 is gripped.

[0020] 2 and 8, ribs 22 extending downward are formed on the underside of the jig flange 20 from the front edge, rear edge, and the outer edge of the left and right edges. When the construction jig 1 is placed over the cover 90, the ribs 22 of the jig flange 20 function as abutment portions that abut against the cover flange 92. The surface 23 of the underside of the jig flange 20 excluding the ribs 22 is designed not to abut against the cover flange 92.

[0021] 1 to 3 and 7, the cutting position guide 30 extends from one jig flange 20 to the other jig flange 20 at the front end of the construction jig 1, via the jig body 10. In detail, the cutting position guide 30 has a flange shape that extends from the end of the jig body 10 toward the outside of the jig body 10 in a direction perpendicular to the axial direction L1. The cutting position guide 30 can guide a cutting tool such as a saw when cutting the cover 90, and can also guide when marking the cutting position on the cover 90.

[0022] 1 and 7, the first drilling position guide 40 includes a plurality of cylindrical metal fittings 41 attached to the jig flange 20. Holes of different diameters are formed in the plurality of metal fittings 41. The metal fittings 41 penetrate the jig flange 20 from the top to the bottom, and therefore the holes formed in the metal fittings 41 also penetrate the jig flange 20 from the top to the bottom. The ridges 21 of the jig flange 20 are aligned with the centers of the holes in the metal fittings 41 in the front-to-rear direction.

[0023] 4 and 7, the first drilling position guide 40 is provided on the rear end surface of the jig flange 20 and includes a recess 42 extending in the vertical direction. The recess 42 is aligned with the left-right center of the hole in the metal fitting 41. The first drilling position guide 40 can guide a drill or other drilling tool when drilling holes in the cover flange 92 of the jig flange 20, and can also provide guidance when marking drilling positions on the cover flange 92 (guiding a marking tool such as a marker or punch).

[0024] 1 and 7, the second drilling position guide 50 is provided at the circumferential center and rear end of the jig body 10, and has a circular hole 51. The second drilling position guide 50 can guide when marking a drilling position on the cover body 91 at the circumferential center of the jig body 10.

[0025] Next, a procedure for processing the cover 90 using the installation jig 1 will be described with reference to FIGS. When cutting the cover 90 to a predetermined length, as shown in FIG. 9 , the construction jig 1 is placed over the surface of the cover 90 so that the cutting position guide 30 is at cutting position P1. While holding the construction jig 1 still, a cutting tool such as a saw can be moved along the cutting position guide 30 to perform a straight cut at a perpendicular angle to the axial direction L2 of the cover 90. Alternatively, a marking tool such as a marker can be moved along the cutting position guide 30 to perform a straight marking at a perpendicular angle to the axial direction L2 of the cover 90. The cover 90 is then cut using the cutting tool along the marking line on the cover 90. Note that when the construction jig 1 is placed over the cover 90, the axial direction L1 of the construction jig 1 coincides with the axial direction L2 of the cover 90.

[0026] When drilling pilot holes D in the cover flange 92 of the cover 90 for screws to secure the cover 90, the hole in the metal fitting 41 that corresponds to the size of a drill or other drilling tool used to drill the pilot holes D is aligned with the position where the pilot holes D will be drilled. By passing the drilling tool through the hole in the metal fitting 41 of the first drilling position guide 40 while holding the construction jig 1 still, the drilling tool can be stably drilled at a predetermined position in the cover flange 92 without misalignment. Alternatively, the recess 42 of the first drilling position guide 40 can be aligned with the position where the pilot holes D will be drilled, and a marking tool such as a marker can be placed on the cover flange 92 at the position of the recess 42 to mark the predetermined drilling position P2. Then, using the marking at the drilling position P2 as a guide, the pilot holes D are formed in the cover flange 92 with the drilling tool.

[0027] In some cases, the cover 90 covers not only the pipe but also the valve connected to the pipe. In this case, it is necessary to open a circular opening E in the center of the cover body 91 and expose a handle for opening and closing the valve from the opening E to the outside of the cover 90. To do this, a marking tool such as a marker can be inserted into the hole 51 to mark a drilling position P3, which will be the center of the opening E, at the center of the cover body 91 in the left-right direction W. Thereafter, the opening E is formed in the cover body 91 using a drilling tool, using the marking at the drilling position P3 as a guide.

[0028] 10, when the construction jig 1 is placed over the cover 90, the rib 22 abuts against the cover flange 92, while the surface 23 of the jig flange 20 does not abut against the cover flange 92, leaving a gap G1 between the cover flange 92 and the jig flange 10. Therefore, the metal fittings 41 of the first drilling position guide 40 are spaced apart from the cover flange 92 without abutting against it. Furthermore, a small gap G2 exists between the upper wall 11 of the jig body 10 and the cover body 91. In other words, the upper wall 11 and the cover body 91 are slightly spaced apart without abutting against each other.

[0029] Next, the effects of this embodiment will be described. (1) For the cover 90 having a half-split cylindrical cover body 91 and a cover flange 92, the construction jig 1 has a half-split cylindrical jig body 10 and a jig flange 20 that abuts against the cover flange 92, so the construction jig 1 can be placed stably on the cover 90. Therefore, the cutting position guide 30, the first drilling position guide 40, and the second drilling position guide 50 are stable relative to the cover 90, making it easier to process the cover 90.

[0030] (2) The side wall portion 15 of the jig body 10 is provided with a thick portion 16. This improves the strength of the jig body 10, making it less susceptible to deformation, and making the construction jig 1 more stable during processing. Furthermore, since the side surface 16a of one thick portion 16 and the side surface 16a of the other thick portion 16 extend substantially parallel to each other, the side wall portion 15 is easier to grip than when the side wall portion 15 is curved.

[0031] (3) A rib 17 is formed at the rear end of the jig body 10, which improves the strength of the jig body 10 and makes it less likely to deform, making the construction jig 1 more stable during processing work.

[0032] (4) The ridge 21 of the jig flange 20 is aligned with the center of the hole in the metal fitting 41 in the front-to-rear direction. Therefore, by visually checking the ridge 21, it is easy to recognize the position of the hole in the metal fitting 41, and the first drilling position guide 40 can be easily aligned to the specified position. (5) Both side surfaces of the jig flange 20 have a smooth, uneven shape, and furthermore, a plurality of ridges 21 are formed on both side surfaces of the jig flange 20 (specifically, on the apexes of the convex portions of the uneven shape). The uneven shape of the jig flange 20 and the ridges 21 function as anti-slip surfaces when the jig flange 20 is gripped, making the processing operation using the jig 1 easier.

[0033] (6) A small gap G2 exists between the upper wall portion 11 of the jig body 10 and the cover body 91. For this reason, for example, if the cutting position guide 30 is soiled with a marking tool such as a marker, even if the construction jig 1 is rubbed on the cover 90 while the construction jig 1 is still covered by the cover 90, it is possible to prevent the dirt from the marking tool from adhering to the cover body 91.

[0034] (7) When the installation jig 1 is placed over the cover 90, a gap G1 exists between the surface 23 of the jig flange 20 and the cover flange 92, preventing the metal fittings 41 from coming into contact with the cover flange 92. This prevents the metal fittings 41 from damaging the cover flange 92.

[0035] [Second embodiment] Next, a second embodiment will be described with reference to Figures 11 to 20. The construction jig 2 of the second embodiment is different from the construction jig 1 of the first embodiment in the configuration of the connecting portion 12 of the jig body 10, the configuration of the side wall portion 15 of the jig body 10, the configuration of the underside of the jig flange 20, and the configuration of the first drilling position guide 40, but is otherwise identical in configuration. The same components as those of the first embodiment are designated by the same reference numerals, and redundant explanations will be omitted.

[0036] As shown in Figures 11 and 17, the connecting portion 12 of the jig body 10 of the construction jig 2 of the second embodiment does not have the recess 12a of the first embodiment, and the upper surface of the connecting portion 12 is a smooth surface.

[0037] As shown in Figures 11, 15 and 16, the side wall portion 15 of the jig body 10 of the construction jig 2 of the second embodiment has a rib 18 extending in the axial direction L1 of the construction jig 2, rather than the thick-walled portion 16 of the first embodiment.

[0038] As shown in FIGS. 12 and 18, no ribs 22 are formed on the lower surface of the jig flange 20 of the installation jig 2, and the entire lower surface of the jig flange 20 abuts against the cover flange 92.

[0039] As shown in FIG. 14, the rear end surface of the jig flange 20 does not have the recess 42 of the first embodiment, and is a flat surface.

[0040] The construction jig 2 of this embodiment has the following advantages in addition to the advantages (1) and (3) to (6) of the first embodiment. (8) The side wall portion 15 of the jig body 10 is provided with ribs 18. This improves the strength of the jig body 10, making it less susceptible to deformation, and making the construction jig 2 more stable during processing.

[0041] [Other embodiments] The above embodiment can be modified as follows, for example: The above embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The construction jigs 1 and 2 may be modified to process a cover having a cover body with a shape different from the half-split cylindrical cover body 91. For example, to process a cover having a half-split square tubular cover body, the jig body 10 may be formed in a half-split square tubular shape corresponding to the cover body.

[0042] The cutting position guide 30 of the above embodiment may be fitted with a metal plate or a plate made of a resin (such as polyacetal (POM) resin) that is more wear-resistant than the resin that constitutes the construction jigs 1 and 2. Alternatively, the cutting position guide 30 of the above embodiment itself may be made of metal or a wear-resistant resin. The second drilling position guide 50 may be provided with a metal fitting similar to the metal fitting 41 so that the second drilling position guide 50 can guide the drilling tool when drilling the cover body 91.

[0043] The construction jigs 1 and 2 may be provided with only one or two of the cutting position guide 30, the first drilling position guide 40, and the second drilling position guide 50. For example, the construction jigs 1 and 2 may be provided with only the cutting position guide 30, and the first drilling position guide 40 and the second drilling position guide 50 may not be provided.

[0044] Each first drilling position guide 40 may have one or two metal fittings 41, or may have four or more metal fittings 41. In each first drilling position guide 40, the metal fitting 41 may be omitted. The connecting portion 12 may be omitted. [Explanation of symbols]
