Description

[Technical Field]

[0001] The present invention relates to a shoelace structure, a shoelace installation method, and a shoelace fixing member. [Background technology]

[0002] The Ministry of Land, Infrastructure, Transport and Tourism's Standard Specifications for Building Construction require that door frames of steel door fixtures installed on concrete substrates be filled with mortar. Furthermore, if mortar cannot be filled after the frame is fixed to the building frame, it is recommended that mortar be filled before installation, as is done at many construction sites. In particular, the door frame, which constitutes the door frame, is a component that is continuous with the floor surface, and therefore must be filled with mortar so as to eliminate voids. For example, the door frame disclosed in Patent Document 1 is constructed by directly fixing the bottom of a U-shaped base frame with an open top to the floor surface, filling the base frame with mortar, covering the top surface of the mortar from above with a U-shaped base frame with an open bottom, and fixing the sides of the base frame to the sides of the base frame. This results in a structure in which the interior of the door frame is filled with mortar. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-256934 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the construction of steel door frames requires the removal of the concrete floor where the frame will fit, and the floor and frame are then fixed at a level, typically by welding. The three-sided frames that make up steel door frames, i.e., vertical frames, are typically fixed using a fireless method that does not require welding, allowing them to be fixed to the building frame. However, it has been difficult to apply the same fireless construction method and structure to the frame frames. Unlike the frame frames, the frame frames are fixed at a level relative to the floor, and as mentioned above, the frame frames are filled with mortar, making screw fastening difficult and necessitating welding. Therefore, to completely eliminate the need for firearms in the construction of frame frames, a method that does not comply with the Ministry of Land, Infrastructure, Transport and Tourism's standard specifications, i.e., retrofitting the frame frames, is necessary, which results in a complex structure and is therefore ineffective.

[0005] The present invention has been made in consideration of the above situation, and its purpose is to provide a structure of a shoe that can be installed without firearms and that can achieve completely fireproof installation of the frame, a method of installing a shoe, and a fixing member for the shoe. [Means for solving the problem]

[0006] Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments. The structure of a chain according to claim 1 of the present invention comprises a chain body 13 having a long, strip-shaped upper surface 11, a chain fixing part 17 fixed to a lower surface 15 of the chain body 13, a groove 21 formed by cutting through a floor surface 19 with a width greater than the width of the chain body 13 and in which the chain body 13 is placed, and a filler 65 filled into the groove 21 with the upper surface 11 of the chain body 13 exposed. The hanging fixing portion 17 comprises a base portion 37 fixed to the lower surface 15, a wing portion 39 extending from the base portion 37 and gradually moving away from the lower surface 15, and a tip portion 40 formed at the extending tip of the wing portion 39 and facing toward the bottom surface 29 of the groove 21 and abutting against the bottom surface, and is characterized in that the tip portion 40 is fixed to the bottom surface 29 of the groove 21 by a fixing means 49.

[0007] In the structure of this strap 23, a strap fixing part 17 is fixed to the underside 15 of the strap body 13. The strap fixing part 17 is fixed to the underside 15 opposite the bottom surface 29 of the groove 21. The strap fixing part 17 has a base part 37 fixed to the underside 15 of the strap body 13. Wing portions 39 extend from the base portion 37. The wing portions 39 are formed from the same material as the base portion 37 and extend from the base portion 37. As the wing portions 39 extend from the base portion 37, they are bent in advance at an angle that moves them away from the lower surface 15 of the roller body 13. The slipper body 13 is fixed to a three-sided jamb 33. The three-sided jamb 33 has a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame. The slipper body 13 is fixed by connecting the lower ends of the vertical frames 35 of the three-sided jamb 33. When the three-sided jamb 33 is set in place, the slipper body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21. After the positioning of the shoelace body 13 is completed, the shank 53 of a tool 51 such as a screwdriver is inserted between the underside 15 and the wing 39. The wing 39 is deformed by being pressed downward by the shank 53, and is further bent until it abuts against the bottom surface 29. The downwardly bent wing portions 39 have tip portions 40 at the extending ends of the wing portions 39 fixed to the bottom surface 29 using fixing means 49 such as screws. As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 29 of the groove 21 via the strap fixing portion 17 without any fire. The filler 65 is filled into the groove 21 of the hook body 13, so that at least a portion of the side surface of the hook body 13 excluding the top surface 11 and the hook fixing part 17 are embedded in the filler 65 which is flush with the floor surface 19. In this sheath structure, the sheath body 13 forms a truss structure with the sheath fixing parts 17 embedded in the filler 65, and is firmly fixed to the bottom surface 29 of the groove 21. The sheath fixing parts 17 have a simple structure consisting of a base part 37 and wing parts 39, and are formed as a single part and fixed to the sheath body 13. Therefore, the sheath body 13 can be fixed to the bottom surface 29 of the groove 21 with a simple structure and without welding, and without increasing the number of parts. Because construction can be completed without welding, i.e., without firearms, there is no need for complicated work such as preparing welding equipment and carrying it in and out, making construction easier and shortening the construction time.

[0008] The structure of the sling described in claim 2 of the present invention is the structure of the sling described in claim 1, A folding guide portion 45 is provided at the boundary between the base portion 37 and the wing portion 39 to facilitate folding of the wing portion 39 in a direction away from the lower surface 15 relative to the base portion 37.

[0009] In this structure of the sheath 23, the wings 39 can be bent toward the bottom surface 29, allowing the underside 15 of the sheath body 13 to be connected to the bottom surface 29 via the wings 39. At this time, the metal wings 39 can be easily bent thanks to the bending guides 45 formed between the base plate 37 and the wings 39. The bending guides 45 can be, for example, slits, holes (intermittent holes or continuous holes), grooves, or perforated intermittent holes or intermittent recesses. Even if there is variation in the distance between the underside 15 and the bottom surface 29 of the sheath body 13, changing the bending angle of the wings 39 can absorb this variation and firmly secure the underside 15 to the bottom surface 29.

[0010] The structure of the sling described in claim 3 of the present invention is the structure of the sling described in claim 1 or 2, The tip portion 40 is characterized in that a through hole 47 is drilled therein, through which a fixing means 49 is inserted.

[0011] In the structure of this sheath 23, a through hole 47 is provided in the tip 40 at the extending tip of the wing 39. When the wing 39 is bent downward via the bending guide 45, the tip 40 comes into contact with the bottom surface 29 of the groove 21. This allows the wing 39 to be fixed to the bottom surface 29 by, for example, threading a fixing means 49, such as a screw, inserted through the through hole 47 into the bottom surface 29. This prevents the action of external forces that could cause displacement on the already positioned sheath body 13, allowing the sheath body 13 to be fixed in the accurate position, allowing for the process of filling with the filler 65.

[0012] The structure of the splice according to claim 4 of the present invention is the structure of the splice according to any one of claims 1 to 3, The wing portions 39 are characterized by being constituted by a pair of wings extending from both sides of the base portion 37 in the longitudinal direction of the hook body 13 .

[0013] The structure of this strap 23 is made up of a pair of wings 39, which extend from both longitudinal sides of the strap body 13, sandwiching the base plate 37. The tip ends 40 of the pair of wings 39 are fixed to the bottom surface 29 with fixing means 49 such as screws, so that the strap fixing part 17 forms a triangular truss structure with the base plate 37 as the apex, and is fixed as a support structure between the bottom surface 29.

[0014] The structure of the splice according to claim 5 of the present invention is the structure of the splice according to any one of claims 1 to 4, An embedding portion 57 to be embedded in the filler 65 is fixed to the lower surface 15 of the shoe body 13.

[0015] In the structure of this hook 23, the hook body 13 has an embedded portion 57 provided on the underside 15. The embedded portion 57 is embedded together with the hook fixing portion 17 in the filler 65 filled in the groove 21. Therefore, when the filler 65 hardens, in addition to the fixing strength provided by fixing the hook fixing portion 17 to the bottom surface 29, an additional fixing force is obtained by bonding and integrating the filler with the embedded portion 57.

[0016] The method for constructing the slipcover 23 according to claim 6 of the present invention includes a chipping step of chipping the floor surface 19 to form the groove 21, a fitting process for fitting a hook body 13, which is formed by connecting the lower ends of a pair of parallel vertical frames 35 spaced apart from each other at an upper frame, into the groove 21 and positioning the hook body 13; a bending process of bending wing portions 39 extending from the base portion 37 of the strap fixing portion 17, the base portion 37 being fixed to the underside 15 of the strap body 13, so that tip portions 40 of the tips of the wing portions 39 abut against the bottom surface 29 of the groove 21; a fixing step of abutting the tip portion 40 against the bottom surface 29 and fixing it with fixing means 49; Filling the groove 21 with a filler 65 so that the filler 65 is flush with the floor surface 19 ,above a filler filling step of embedding at least a portion of the side surface of the hook body 13 excluding the surface 11 and the hook fixing part 17; The present invention is characterized by comprising:

[0017] In this construction method for a shoe slide 23, a shoe slide 23 to which a shoe slide fixing part 17 is fixed is used for construction. The shoe slide fixing part 17 has wings 39 extending from a base part 37 fixed to the underside 15. The shoe slide main body 13 is fixed to a three-sided jamb 33. That is, the shoe slide main body 13 is fixed by connecting the lower ends of the vertical frames 35 of the three-sided jamb 33. In an opening in the building frame, for example, where the three-sided jamb 33 is to be attached, a groove 21 is formed in advance by cutting the floor surface 19 so that the shoe slide main body 13 can be placed. In the erection process, the three-sided jamb 33 is erected, so that the shoe slide main body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21. After the positioning of the shoe strap body 13 is completed, the shank 53 of a tool 51 such as a screwdriver is inserted between the lower surface 15 and the wing 39 in the bending process. The shank 53 presses the wing 39 downward, deforming it and bending it further until it contacts the bottom surface 29. In the fixing step, the bent wing portions 39 are fixed, that is, fastened, at the tip ends 40 of the extended ends of the wing portions 39 to the bottom surface 29 using fixing means 49 such as screws. As a result, the strap body 13, which has been positioned, is fixed to the bottom surface 29 of the groove 21 via the strap fixing portion 17. In the filler filling process, filler 65 is filled into the grooves 21 of the hook body 13, forming a filler finish surface 67 that is flush with the floor surface 19. The filler 65 buries at least a portion of the side surface of the hook body 13, excluding the top surface 11, and the hook fixing part 17. In this method of installing the sheath 23, the sheath body 13 is firmly fixed to the bottom surface 29 of the groove 21 in a truss structure by the sheath fixing parts 17 embedded in the filler 65. The sheath fixing parts 17, which are fixed to the sheath body 13, are fixed to the bottom surface 29 by fixing means 49. Therefore, in this method of installing the sheath 23, welding is not performed, that is, the installation is performed without firearms, eliminating the need for welding equipment and allowing the sheath body 13 to be fixed to the bottom surface 29 of the groove 21 with a simple structure and without increasing the number of parts.

[0018] The seventh aspect of the present invention provides a fastening member 55 for a string, which is fixed to the underside 15 of a string body 13 having a long, strip-shaped upper surface 11, and is fixed to the bottom surface 29 of a groove 21 formed by cutting a floor surface 19 with a width wider than the width of the string body 13. The fastening member 55 is embedded in a filler 65 that fills the groove 21 with the upper surface 11 of the string body 13 exposed, a base portion 37 fixed to the lower surface 15; wing portions 39 extending from the base portion 37 and gradually moving away from the lower surface 15; and a tip portion 40 formed at the extending tip of the wing portion 39, facing toward a bottom surface 29 of the groove 21, abutting against the bottom surface 29 and fixed by a fixing means 49. The present invention is characterized by comprising:

[0019] In this strap fixing member 55, wings 39 having a tip 40 are formed on a base plate 37 fixed to the underside 15 of the strap body 13. In other words, the strap fixing member 55 has a simple structure consisting of the base plate 37, wings 39, and tip 40, and is formed as a single component that is attached and fixed to the strap body 13. The base plate portion 37 of the strap fixing member 55 is fixed to the lower surface 15 of the strap body 13 by, for example, welding, and is integrated with the strap body 13 . After the positioning of the shoelace body 13 is completed, the shank 53 of a tool 51 such as a screwdriver is inserted between the underside 15 and the wing 39. The shank 53 of the tool presses the wing 39 downward, deforming it and bending it further until it abuts against the bottom surface 29. The bent wing portions 39 have tip portions 40 that abut against the bottom surface 29 at the extending ends of the wing portions 39 and are fixed to the bottom surface 29 by fixing means 49 such as screws. As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 29 of the groove 21 via the strap fixing member 55 without any fire. The fixing member 55 for the hook is embedded in the filler 65 which is flush with the floor surface 19 by filling the groove 21 with the filler 65, together with at least a portion of the side surface of the hook body 13 excluding the top surface 11. The strap fixing member 55 has a truss structure that supports the strap body 13 between itself and the bottom surface 29 of the groove 21, firmly fixing it in place. Therefore, the strap fixing member 55 does not require welding, has a simple structure, and can fix the strap body 13 to the bottom surface 29 of the groove 21 without increasing the number of parts.

[0020] The shoe fixing member 55 according to claim 8 of the present invention is the shoe fixing member 55 according to claim 7, A folding guide portion 45 is provided at the boundary between the base portion 37 and the wing portion 39 to facilitate folding of the wing portion 39 in a direction away from the lower surface 15 relative to the base portion 37.

[0021] In this fastening member 55 for a string, the wings 39 can be bent toward the bottom surface 29, thereby connecting the underside 15 of the string body 13 to the bottom surface 29 via the wings 39. The metal wings 39 can be easily bent thanks to the bending guides 45 formed between the base plate 37 and the wings 39. The bending guides 45 can be, for example, slits, holes (intermittent holes or continuous holes), grooves, or perforated intermittent holes or intermittent recesses. Even if there is variation in the distance between the underside 15 and the bottom surface 29 of the string body 13, changing the bending angle of the wings 39 can absorb this variation and firmly fasten the underside 15 to the bottom surface 29.

[0022] The shoe fixing member 55 according to claim 9 of the present invention is the shoe fixing member 55 according to claim 8, The wing portions 39 are characterized by being constituted by a pair of wings extending from both sides of the base portion 37 in the longitudinal direction of the hook body 13 .

[0023] In this strap fixing member 55, a pair of wings 39 are provided extending from both longitudinal sides of the strap body 13, sandwiching the base plate 37. When the tip ends 40 of the pair of wings 39 are fastened to the bottom surface 29 with fixing means 49 such as screws, the strap fixing member 17 forms a triangular truss structure with the base plate 37 as the apex, which acts as a support structure between the bottom surface 29 and the truss structure, and is fixed. [Effects of the Invention]

[0024] According to the structure of the hook described in claim 1 of the present invention, the hook fixing part on the underside of the hook body is bent toward the bottom of the groove, and its tip is fixed with a fixing means, making it possible to fix the hook body. This allows the hook to be installed without fire, meaning that installation can be completed without using any welding equipment. This eliminates the need for complicated work processes such as preparing, carrying in, and carrying out the welding equipment, simplifies installation, shortens installation time, and enables completely fireless installation of three-sided frames.

[0025] According to the structure of the spiral spool described in claim 2 of the present invention, the bending guide portion provided between the base portion and the wing portion serves as the base and center of bending, making it easier to bend the wing portion, and the tip portion can be easily brought into contact with the bottom surface of the groove.

[0026] According to the structure of the hook described in claim 3 of the present invention, the wing portion can be bent toward the bottom surface of the groove, and the tip portion can be abutted against the bottom surface while the through hole can be placed against the bottom surface, making it easier to screw the fixing means into the bottom surface while making it less likely for the hook body to become misaligned.

[0027] According to the structure of the strap of the fourth aspect of the present invention, the pair of wings that sandwich the base plate are supported on the bottom surface of the groove, and the strap body can be firmly fixed to the bottom surface.

[0028] According to the structure of the hook described in claim 5 of the present invention, in addition to the hook fixing part, the embedding part provided on the underside of the hook body can also be embedded in the filler, so that the hook body can be more firmly fixed to the filler. As a result, when the filler hardens, in addition to the fixation strength due to the hook fixing part being fixed to the bottom surface, further fixation force is obtained by the filler adhering and integrating with the embedding part.

[0029] According to the method for installing a hook as set forth in claim 6 of the present invention, the hook fixing part on the underside of the hook body is bent toward the bottom of the groove and its tip is fixed with a fixing means, thereby enabling the hook body to be fixed. This allows the hook to be installed without fire, i.e., installation can be completed without using any welding equipment, eliminating the need for complicated work processes such as preparing, carrying in, and carrying out the welding equipment, simplifying installation and shortening installation time, and enabling completely fireless installation of three-sided frames.

[0030] According to the seventh aspect of the present invention, the wing fixing member for a hook is attached to the underside of the hook body, bending the wings toward the bottom of the groove and fixing the tips of the wings to the bottom with a fixing means, thereby fixing the hook body. The fixed hook fixing member forms a truss structure, providing a strong support structure between the bottom and the hook body. This allows the hook to be installed without firearms. In other words, it serves as an intermediate member for fixing the hook body to the bottom of the groove, and installation can be completed without the use of welding equipment. This eliminates the complicated work processes of preparing, transporting, and removing the welding equipment, simplifies installation, shortens installation time, and enables completely fireless installation of three-sided frames.

[0031] According to the fixing device for hanging described in claim 8 of the present invention, the folding guide portion provided between the base portion and the wing portion can be used as the base and center of folding, making it easy to bend the wing portion toward the bottom surface of the groove, thereby improving workability.

[0032] According to the fixing member for a hook described in claim 9 of the present invention, the tip ends of the pair of wings are fixed to the bottom surface by a fixing means, thereby increasing the number of fixing points to the bottom surface, forming a triangular truss structure with the base portion as the apex, which acts as a support structure between the bottom surface and the hook body, allowing the hook body to be firmly fixed to the bottom surface.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the structure of a hook according to the first embodiment. The structure of the slider according to this embodiment comprises a slider body 13 having a long, strip-shaped upper surface 11, a slider fixing part 17 fixed to the lower surface 15 of the slider body 13, a groove 21 cut into the floor surface 19 with a width wider than the width of the slider body 13 and inside which the slider body 13 is placed, and a filler 65 filled into the groove 21 with the upper surface 11 of the slider body 13 exposed. The filler 65 may be mortar, concrete, or an adhesive anchor such as Chemical Anchor (registered trademark), but in the following embodiments, the filler 65 will be described as mortar 65.

[0035] The shoe 23 is generally composed of a shoe body 13 and a shoe fixing part 17. In this embodiment, the threading body 13 is formed as a long angle bar with a U-shaped cross section perpendicular to the longitudinal direction and opening downward. The threading body 13 is preferably made of a material such as steel, stainless steel, or aluminum. The threading body 13 has a pair of side plates 27 hanging down from each of a pair of long sides along the longitudinal direction of the smooth upper surface 11, at least one of which has a filler introduction section 25 through which mortar 65 passes. In this embodiment, one of the pair of side plates 27 is shorter and hangs down than the other. This ensures the filler introduction section 25 between the other side plate 27 and the bottom surface 29 of the groove 21.

[0036] In the structure of the hook of this embodiment, a filler member 31 is provided between a pair of side plate portions 27 to fill the gap between the underside 15 of the hook body 13 and the mortar 65. The filler member 31 can be, for example, a steel plate. In the figure, two plates are stacked to obtain a predetermined thickness, but the filler member 31 can be installed with a thickness equal to or slightly longer than the length of the short side plate portion 27 to match the hanging length of the side plate portion 27.

[0037] The shoe slide 23 is fixed to a three-sided frame 33 and transported to the construction site. The three-sided frame 33 has a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame (not shown). The shoe slide 23 is installed with the shoe slide main body 13 connecting the lower ends of the vertical frames 35 of the three-sided frame 33. In other words, the installation of the shoe slide 23 makes the three-sided frame 33 a square frame (four-sided frame).

[0038] FIG. 2 is an exploded perspective view of the shoelace 23. As shown in FIG. The strap fixing part 17 comprises a base part 37 fixed to the underside 15 of the strap body 13, wing parts 39 extending from the base part 37 and gradually moving away from the underside 15, and a tip part 40 formed at the extending tip of the wing part 39 facing the bottom surface 29 of the groove 21 and abutting against this bottom surface.

[0039] The strapping fixture 17 is formed separately from the strapping body 13. The strapping fixture 17 is formed in the shape of a long strip that extends along the longitudinal direction of the strapping body 13. The strapping fixture 17 is made of, for example, steel. A suitable steel material is steel. The strapping fixture 17 is formed into a roughly W-shape in side view by sheet metal processing or the like. The center of the strapping fixture 17 in the longitudinal direction forms a rectangular flat plate-shaped base plate 37. The base plate 37 is fixed to the underside 15 of the strapping body 13 by, for example, welding at a joint 43. As a result, the strapping fixture 17 can be transported to the construction site together with the strapping body 13.

[0040] The wing portions 39 are formed as a pair, each extending from both sides of the base plate portion 37 in the longitudinal direction of the sheath body 13. The wing portions 39 are formed in a rectangular shape that is longer in the longitudinal direction of the sheath body 13 than the base plate portion 37. Each of the pair of wing portions 39 extends from the base plate portion 37, and as it moves away from the base plate portion 37, its tip portion 40 is inclined downward, i.e., is bent in a mountain-like shape, so as to move away from the underside 15 of the sheath body 13.

[0041] The hanging fixture 17 is provided with a folding guide portion 45 at the boundary between the base plate 37 and the wing portions 39. The folding guide portion 45 makes it easy to fold the wing portions 39 relative to the base plate 37. The hanging fixture 17 constitutes a triangular truss, which will be described later, and is therefore formed of a steel plate or the like having a predetermined thickness. Therefore, by providing the folding guide portion 45, the hanging fixture 17 makes it easy to fold the wing portions 39 at the boundary with the base plate 37. The folding guide portion 45 can be, for example, a slit, a hole (intermittent hole, continuous hole), a recessed groove, a perforated intermittent hole, an intermittent recess, or the like.

[0042] A bent portion 41 is formed at tip portion 40. Bent portion 41 is formed by folding tip portion 40 of each wing portion 39 in a valley shape in the opposite direction to the bending direction of folding guide portion 45. That is, bent portion 41 is V-shaped in side view.

[0043] The strap fixing portion 17 has a through hole 47 formed at the bent portion 41 for inserting a fixing means 49. The through hole 47 is an elongated hole with its major axis extending along the ridge line and valley bottom of the bent portion 41. The bent portion 41 first comes into contact with the bottom surface 29 of the groove 21 when the wing portion 39 is bent away from the underside 15 of the strap body 13. In this embodiment, two through holes 47 are provided in the width direction of the wing portion 39. The number of through holes 47 is not limited to this.

[0044] FIG. 3 is a plan view of the strap fixing part 17 as seen from the strap main body 13 side. A fastening means 49, such as a concrete screw or a concrete nail, is inserted into the through-hole 47. Alternatively, the fastening means 49 may be a screw or bolt that is threaded into a threaded object that is previously inserted into a pilot hole drilled in the bottom surface 29. The fastening means 49 is formed by bending the tip 40 of each wing 39 in a direction away from the underside 15 of the threading body 13, and inserting the through-hole 47 into the through-hole 47 after the through-hole 47 is in contact with the bottom surface 29 of the groove 21. In other words, the through-hole 47 also serves as a positioning means when screwing the fastening means 49 into the bottom surface 29. In this embodiment, the two through-holes 47 spaced apart in the plate width direction along the bent portion 41 are alternately used on the left and right sides in the plate width direction in the wing 39 on one side and the wing 39 on the other side. In other words, the through-hole 47 on the right side in the plate width direction is used in the wing 39 on the upper side of FIG. 3, and the through-hole 47 on the left side in the plate width direction is used in the wing 39 on the lower side of FIG. 3. As a result, the strap fixing portion 17 can fix the strap body 13 to the bottom surface 29 of the groove 21 with an equal fixing force from both sides of the strap body 13 in the board width direction.

[0045] FIG. 4 is a vertical cross-sectional view of the sheave 23 fixed in the groove 21 in a direction perpendicular to the longitudinal direction. In the structure of the slipper, the slipper 23 is placed in the groove 21, the slipper fixing part 17 is fixed by the fixing means 49, and then mortar 65 is filled into the groove 21. The mortar 65 forms a finished surface 67 that is flush with the floor surface 19. The slipper 23 has an upper surface 11 exposed from the floor mortar finished surface 67, and the slipper fixing part 17 is embedded in at least a portion of the side surface of the slipper body 13 excluding the upper surface 11. In this embodiment, as will be described later, the fixing members 49 are each inclined to fix the slipper fixing part 17 to the bottom surface 29.

[0046] FIG. 5 is a longitudinal cross-sectional view of the slip ring 23 fixed in the groove 21 in the longitudinal direction. The slide body 13 is supported on the bottom surface 29 of the groove 21 via the slide fixing part 17 fixed to the underside 15. As a result, the slide 23 is supported on the bottom surface 29 with the slide fixing part 17 forming a V-shape. These paired wings 39 then become inclined sides, forming a triangular truss structure that is fixed to the bottom surface 29 and embedded in mortar 65. By forming a triangular truss, the slide fixing part 17 can support the load from the slide body 13 with high strength.

[0047] A plurality of the strap fixing parts 17 are fixed at intervals along the length of the strap body 13. The spacing between the strap fixing parts 17 is set according to the length of the strap body 13. For example, if the length of the strap body 13 is about 900 mm, the strap fixing parts 17 are provided in three positions: one about 150 mm from each end of the strap body 13, and another intermediate position, i.e., a position spaced about 300 mm apart. Alternatively, if the length of the strap body 13 is about 1,300 mm, the strap fixing parts 17 are provided in three positions: one about 150 mm from each end of the strap body 13, and another intermediate position, i.e., a position spaced about 500 mm apart.

[0048] Next, the construction method of the above-mentioned Kutsuri will be explained.

[0049] The method for constructing a kutsusuri according to this embodiment includes a chipping process, a setting process, a bending process, a fixing process, and a filler filling process.

[0050] In the chipping process, the floor surface 19 is chipped to form grooves 21. The grooves 21 are formed with a width greater than the width of the boards of the wall frame 13. The width of the grooves 21 is also greater than the width of the vertical frames 35 of the jamb. The wall frame 13 is positioned so that the top surface 11 of the wall frame 13 is flush with the floor surface 19 or protrudes by about 3 mm, and the grooves 21 are formed with a depth that provides a space below the wall frame 13 into which mortar 65 can flow, i.e., a filler introduction section 25.

[0051] In the erection process, the slide 23 is attached to the frame 33 and erected. The frame 33 is formed by connecting the upper ends of a pair of parallel, spaced-apart vertical frames 35 with an upper frame (not shown). The slide 23 is installed in a state where the lower ends of the vertical frames 35 of the frame 33 are connected. In other words, the frame 33 becomes a square frame (four-sided frame) with the slide 23 installed. In the erection process, the frame 33 with the slide 23 attached is erected so that the slide main body 13 is positioned in a predetermined position in the groove 21. In other words, the frame 33 and the slide main body 13 are fixed to the main body (not shown) at the predetermined positioned positions.

[0052] FIG. 6 is a procedure explanatory diagram showing the state of the bending process. In the bending process, the wing portions 39 of the sheathing fixture 17, which is fixed to the underside 15 of the sheathing body 13, are bent downward. The bending process involves inserting the shank 53 of a tool 51, such as a screwdriver, between the sheathing body 13 and the wing portions 39, and using the shank 53 to deform the wing portions 39 by pressing them downward. Because the sheathing body 13 is positioned within the groove 21 and the sheathing fixture 17 is fixed to the underside 15 of the sheathing body 13, the shank 53 of the tool 51 is inserted obliquely, and the tip of the shank 53 is pushed downward while the grip of the tool 51 is raised to pry the tool 51. When the tool 51 pushes downward, the bending guide portion 45 becomes the center of bending, the wing portions 39 of the sheathing fixture 17 are bent, and the bending portion 41 abuts against the bottom surface 29 of the groove 21.

[0053] FIG. 7 is a procedure explanatory diagram showing the state of the fixing step. In the fixing process, with the bent portion 41 abutting against the bottom surface 29, screws 49, which are fixing members, are inserted into the through holes 47 in contact with the bottom surface 29 and screwed into the bottom surface 29 to fasten the bent portion 41 to the bottom surface 29. Note that because the sheath body 13 is positioned within the groove 21 and the sheath fixing part 17 is fixed to the underside 15 of the sheath body 13, the shank 53 of the tool 51 cannot press the bent portion 41 from directly above. However, as shown in FIG. 7, the tool 51 is used from an oblique direction, and the screws 49 are inserted into the through holes 47 at the oblique direction and fastened to the bottom surface 29 at that angle. As described above, by using the two through holes 47 alternately on the left and right sides of one wing portion 39 and the other wing portion 39, the bent portion 41 is fastened at different angles, for example, in a substantially perpendicular direction, and is arranged so as to intersect in a vertical cross-sectional view of the sheath 23 in a direction perpendicular to the longitudinal direction, as shown in FIG.

[0054] The bottom surface 29 of the groove 21 is formed in the chipping process, but is not formed as a smooth surface. Rather, it is formed by excavating it with an electric pick or drill, resulting in a discontinuous, uneven surface, which causes variations in the distance from the sheathing body 13, i.e., the distance between the bottom surface 29 and the underside 15 of the sheathing body 13. However, by changing the bending angle of the wing portion 39 and by abutting the ridge portion where the tip end 40 of the wing portion 39 is linear rather than a flat surface, this variation can be absorbed and the tip end 40 of the wing portion 39 can be fixed, making it possible to firmly fix the underside 15 to the bottom surface 29.

[0055] In the filler filling process, mortar 65 is filled into the groove 21 in which the baseplate body 13 is placed, so as to form a finished surface 67 that is flush with the floor surface 19. The mortar 65 embeds at least a portion of the side surface of the baseplate body 13, excluding the top surface 11 of the baseplate body 13. At this time, the mortar 65 flows into the filler introduction section 25, and the baseplate fixing section 17 is simultaneously embedded in the mortar 65. The mortar 65 filled into the groove 21 is allowed to harden while adhering to the bottom surface 15 of the baseplate body 13 and the baseplate fixing section 17. After curing for a predetermined time, the mortar 65 hardens, embedding at least a portion of the side surface of the baseplate body 13, excluding the top surface 11, and the baseplate fixing section 17. The mortar 65 and the baseplate body 13 become one body, completing the construction of the baseplate 23.

[0056] The above-mentioned strap fixing part 17 may be fixed to the underside 15 of the strap body 13 and used integrally with the strap body 13, or may be handled as a separate component from the strap body 13. In this case, the strap fixing part 17 separate from the strap body 13 can be referred to as a strap fixing member 55. The strap fixing member 55 can be attached to the underside 15 of various shapes of strap bodies 13 by attachment means such as welding, screwing, or fastening.

[0057] This threading fixture 55 fixes the underside 15 of a threading body 13, which has a long, strip-shaped upper surface 11, to the bottom surface 29 of a groove 21 cut into the floor surface 19 with a width wider than the width of the threading body 13. The threading fixture 55 is embedded in mortar 65 that fills the groove 21 with the upper surface 11 of the threading body 13 exposed. Similar to the threading fixture 17, the threading fixture 55 comprises a base portion 37 fixed to the underside 15, wings 39 extending from the base portion 37 and gradually moving away from the underside 15, and a bent portion 41 formed at a tip 40 at the tip of the wing 39 and folded in a valley.

[0058] Similarly to the spinning fixing part 17 , the spinning fixing member 55 is provided with a folding guide part 45 at the boundary between the base part 37 and the wing parts 39 to facilitate folding of the wing parts 39 relative to the base part 37 . Furthermore, similar to the strapping fixing part 17, the strapping fixing member 55 is configured as a pair of wing parts 39 extending from both sides of the base part 37 in the longitudinal direction of the strapping main body 13.

[0059] Next, a modification of the first embodiment will be described.

[0060] Figure 8 shows modified examples of the hook body 13, where (a) is a longitudinal cross-sectional view of a modified example in which a pair of side plate portions 27 are formed to hang down short, (b) is a longitudinal cross-sectional view of a modified example in which a pair of side plate portions 27 are formed to hang down long, and (c) is a longitudinal cross-sectional view of a modified example that has an embedded portion 57. If the above-mentioned first embodiment of the fastening portion 17 is made into a fastening member 55 as a separate, single component, the shape of the fastening body 13 can easily be adapted to a shape different from that described above. In a modified example of this slipper body 13, as shown in Figure 8(a), the pair of side plate portions 27 may each be formed to be short and hanging down. According to this modified example, the lower ends of both side plate portions 27 and the lower surface 59 of the stuffing member 31 are flush with each other, and a large filler introduction portion 25 with sufficient space can be secured between both side plate portions 27 and the bottom surface 29 of the groove 21.

[0061] As another modification of the hanging body 13, as shown in FIG. 8(b), a pair of side plates 27 may be formed to hang down long. At least one frame member 61 is provided between the pair of side plates 27 at a predetermined position in the longitudinal direction of the hanging body 13, connecting the lower ends of the side plates 27. The frame member 61 serves to secure the base plate 37 of the hanging fixture 17, and is provided in accordance with the number of hanging fixtures 17. According to this modification, the pair of hanging side plates 27 can prevent deformation of the hanging body 13 and increase its rigidity and strength, and the filling member 31 can be omitted. Mortar is filled between the pair of side plates 27.

[0062] As another modification of the stringer body 13, as shown in FIG. 8(c), a pair of side plate portions 27 may be formed to hang down short, and a downwardly protruding embedded portion 57 may be provided on the underside of the stuffing member 31 provided between them. The embedded portion 57 may be, for example, a pair of L-shaped angle bars 63 welded and fixed. The pair of angle bars 63 are fixed to form a T-shape with one vertical piece back to back. The angle bars 63 fixed to the T-shape have a pair of horizontal upper pieces fixed to the stuffing member 31. Therefore, the pair of back-to-back vertical pieces hang down as the embedded portion 57. A plurality of embedded portions 57 may be provided at predetermined intervals along the length of the stringer body 13. The stringer fixing portion 17 may be fixed to the stuffing member 31 between adjacent embedded portions 57. That is, the embedding portions 57 and the fixing portions 17 for the link are alternately arranged in the longitudinal direction of the link body 13. According to this modification, the pair of side plate portions 27 are hung down short, so a large filler introduction portion 25 can be secured that provides sufficient space between the link body 13 and the bottom surface 29. Furthermore, since the embedding portions 57 fixed to the link body 13 are embedded in the mortar 65, the link body 13 can be integrated with the mortar 65 continuously in the longitudinal direction, and the link body 13 can be made less likely to roll up.

[0063] Next, a second embodiment will be described. FIG. 9 is an exploded perspective view showing a modified example of the fastener 17 of the hook structure according to the second embodiment. The hook fixing part 17 may have a tip 40, which is the extending tip of each wing 39, that protrudes outward from one of the side plates 27 of the hook body 13. In this case, a bent part 41 is formed in the tip 40, and a through hole 47 is formed in the bent part 41. In this example, the through hole 47 is located at the tip of the bent part 41 that protrudes outward.

[0064] FIG. 10 is a plan view of the modified example shown in FIG. In the second embodiment, the hook fixing part 17 has a tip 40 that protrudes outward in the width direction beyond the hook body 13. In other words, the wing portions 39 of the hook fixing part 17 do not extend from the base portion 37 along the longitudinal direction of the hook body 13, but rather the tips of the wing portions 39 deviate from the longitudinal direction. As shown in FIG. 10 , when the wing portions 39 are configured as a pair, the tip 40 of each wing portion 39 protrudes from one side of the hook body 13. Furthermore, the through-holes 47 formed in the bent portions 41 of the tip portions 40 are visible from above. In other words, the through-holes 47 are not hidden below the hook body 13. This positioning of the through-holes 47 allows the hook body 13 to be oriented or mounted in a way that suits the orientation, i.e., left-handed or right-handed, of the hook body 13.

[0065] FIG. 11 is a vertical cross-sectional view of the modified example shown in FIG. According to this modification, fixing means 49 such as a screw inserted through the through hole 47 can be fastened to the bottom surface 29 from vertically above with a tool 51 such as a screwdriver without interfering with the chain body 13 and without having to worry about the position of the edge of the groove 21. In particular, because the through hole 47 can be seen from directly above, the fixing means 49 can be inserted and attached beforehand when pressing down with the tool 51, and the downward bending of the wing portion 39 and the fixing of the fixing means 49 can be performed consecutively. This makes it easier to fasten the chain fixing portion 17.

[0066] FIG. 12 is a vertical cross-sectional view showing a modified example in which the modified example of the strap body 13 shown in FIG. 8 is combined with the modified example of the strap fixing part 17 shown in FIG. The operation of each component of this modified example of the second embodiment is the same as that described above. Specifically, according to the modified example of FIG. 12(a), a large filler introduction section 25 with sufficient space between the side plate section 27 and the bottom surface 29 of the groove 21 can be secured, facilitating the process of fastening the hook-and-loop fastener 17 to the bottom surface 29. According to the modified example of FIG. 12(b), the rigidity and strength of the hook-and-loop main body 13 can be increased, the filling member 31 can be omitted, and fastening the hook-and-loop fastener 17 to the bottom surface 29 can be facilitated. According to the modified example of FIG. 12(c), the pair of side plate sections 27 are drooped short, ensuring a large filler introduction section 25 with sufficient space. Furthermore, because the embedding section 57 fixed to the hook-and-loop main body 13 is embedded in the mortar 65, the hook-and-loop main body 13 is less likely to be turned up. Additionally, the process of fastening the hook-and-loop fastener 17 to the bottom surface 29 can be facilitated.

[0067] Next, a third embodiment will be described. FIG. 13 is an exploded perspective view showing another modified example of the strap fastener 17 of the strap structure according to the third embodiment. The hook fixing part 17 may have tip parts 40, which are the extending tips of the pair of wings 39, that protrude outward from the side plate parts 27 on both sides of the hook body 13. In this case, a bent part 41 is formed in each tip part 40, and the through hole 47 is located at the tip of the bent part 41 that protrudes outward from both sides of the hook body 13.

[0068] FIG. 14 is a plan view of the modified example shown in FIG. In the modified version of the third embodiment of the hook fastener 17, the bent portions 41 protrude outward in the width direction of the hook body 13, forming a generally Z-shape in plan view, allowing the through-holes 47 in each tip 40 to be seen. That is, the through-holes 47 are not hidden below the hook body 13. The positions of the through-holes 47 in the tip 40 deviate from the direction in which the wing portions 39 extend from the base 37, i.e., the direction along the longitudinal direction of the hook body 13, and the shape of the wing portions 39 and the tip 40 is bent in an L-shape. However, the shape of the wing portions 39 may also be formed to extend along a line connecting the base 37 and the through-holes 47. That is, the direction in which the wing portions 39 extend from the base 37 in plan view may be offset by a predetermined angle from the longitudinal direction of the hook body 13, so that they extend obliquely from the base 37. In this case, if the bending guide portion 45 is also provided at a slight incline to match this angle, it is possible to prevent twisting or the like from occurring when the wing portion 39 is deformed downward. Depending on the position of the through hole 47, if there is a direction or installation direction of the hook body 13, i.e., left or right, it can be set to match that direction or orientation.

[0069] FIG. 15 is a vertical cross-sectional view of the modified example shown in FIG. According to this modification, the screws 49 inserted into the through holes 47 can be fastened to the bottom surface 29 from vertically above using a tool 51 such as a screwdriver without interfering with the sheath body 13. This facilitates the fastening of the sheath body fixing parts 17. Furthermore, since the sheath body fixing parts 17 can be fixed to the bottom surface 29 from both sides in the width direction of the sheath body 13, the sheath body 13 can be fixed more evenly than in a structure where it is fixed on one side in the width direction, and the sheath body 13 can be made stronger against external forces applied during installation in a direction perpendicular to the longitudinal direction (the left-right direction in FIG. 15). This makes it more difficult for the sheath body 13 to turn over.

[0070] FIG. 16 is a vertical cross-sectional view showing a modified example in which the modified example of the strap body 13 shown in FIG. 8 is combined with the modified example of the strap fixing part 17 shown in FIG. The operation of each component of this modified third embodiment is the same as that of the second embodiment. Specifically, according to the modified example shown in FIG. 16(a), a large filler introduction section 25 with sufficient space can be secured between the side plate 27 and the bottom surface 29 of the groove 21, facilitating the fastening of the fastening member 17 to the bottom surface 29 and preventing the fastening member 13 from rolling up. According to the modified example shown in FIG. 16(b), the rigidity and strength of the fastening member 13 can be increased, the filling member 31 can be omitted, the fastening of the fastening member 17 to the bottom surface 29 can be facilitated, and the fastening member 17 can be prevented from rolling up. According to the modified example shown in FIG. 16(c), the pair of side plate sections 27 are hung down short, ensuring a large filler introduction section 25 with sufficient space. Furthermore, the embedding portion 57 fixed to the sliding body 13 is embedded in the mortar 65, making it difficult for the sliding body 13 to roll up. In addition, the work of fixing the sliding body fixing portion 17 can be made easier, and since the sliding body fixing portion 17 can be fixed to the bottom surface 29 from both sides in the width direction that sandwich the sliding body 13, it is possible to make the sliding body 13 even more difficult to roll up.

[0071] Next, the operation of the above-described configuration will be described.

[0072] In the structure of the strap according to this embodiment, a strap fixing part 17 is fixed to the underside 15 of the strap body 13. The strap fixing part 17 is fixed to the underside 15 opposite the bottom surface 29 of the groove 21. The strap fixing part 17 has a base part 37 fixed to the underside 15 of the strap body 13.

[0073] Wing portions 39 extend from the base portion 37. The wing portions 39 are formed from the same material as the base portion 37 and extend from the base portion 37. As the wing portions 39 extend from the base portion 37, they are bent in advance at an angle that moves them away from the lower surface 15 of the roller body 13.

[0074] The slipper body 13 is fixed to a three-sided jamb 33. The three-sided jamb 33 has a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame. The slipper body 13 is fixed by connecting the lower ends of the vertical frames 35 of the three-sided jamb 33. When the three-sided jamb 33 is set in place, the slipper body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21.

[0075] After the positioning of the shoe strap body 13 is completed, the shank 53 of a tool 51 such as a screwdriver is inserted between the underside 15 and the wing 39. The shank 53 of the tool 51 presses the wing 39 downward, deforming it so that the fold guide 45 is the center of bending, and the wing 39 is bent until it contacts the bottom surface 29.

[0076] The bent wing portions 39 are fixed to the bottom surface 29 by means of fixing means 49 such as screws at bent portions 41 formed at tip portions 40 which are the extending tips of the wing portions 39 .

[0077] As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 29 of the groove 21 via the strap fixing portion 17 without using a welding device, i.e., without using a firearm.

[0078] When the mortar 65 is filled into the groove 21, the mortar 65 forms a finished surface 67 flush with the floor surface 19 of the lashing body 13, and at least a part of the side surface of the lashing body 13 excluding the top surface 11 and the lashing fixing part 17 are embedded in the mortar 656 flush with the floor surface 19.

[0079] In this structure of the shelving unit, the shelving unit body 13 forms a truss structure with the shelving unit fixing part 17 embedded in the mortar 65, which acts as a support structure between the shelving unit body 13 and the bottom surface 29 of the groove 21 and is firmly fixed to this bottom surface 29. The shelving unit fixing part 17 has a simple structure consisting of a base part 37, wings 39, and tip part 40, and is formed as a single part and fixed to the shelving unit body 13. Therefore, the shelving unit body 13 can be fixed to the bottom surface 29 of the groove 21 with a simple structure and without welding, and without increasing the number of parts. Because welding is not required, complicated work such as preparing the welding equipment 107 and carrying it in and out is completely eliminated, making construction easier and shortening the construction time.

[0080] Furthermore, in this sheath structure, by bending the wings 39 toward the bottom surface 29, the underside 15 of the sheath body 13 can be connected to the bottom surface 29 via the wings 39. At this time, the metal wings 39 can be easily bent thanks to the bending guides 45 formed between the base plate 37 and the wings 39. The bending guides 45 can be, for example, slits, holes (intermittent holes or continuous holes), grooves, or perforated intermittent holes or intermittent recesses. Even if there is variation in the distance between the underside 15 and the bottom surface 29 of the sheath body 13, changing the bending angle of the wings 39 can absorb the variation and firmly secure the underside 15 to the bottom surface 29.

[0081] Furthermore, in this chain structure, a valley fold 41 is provided at tip 40, which is the extending tip of wing 39. When wing 39 is bent downward via bend guide 45, the ridge portion of bent portion 41, which forms the lower edge of bent portion 41, comes into contact with bottom surface 29 of groove 21. Through holes 47 are drilled in bent portion 41. By fastening means 49, such as a screw, inserted through through hole 47 and screwed into bottom surface 29, the portion of wing 39 that abuts against bottom surface 29 upon bending can be fixed in a state of abutment against bottom surface 29. Therefore, external forces that could cause misalignment during construction can be prevented from acting on chain body 13, which is pre-positioned to the frame via jamb 33, and chain body 13 can be fixed in the exact position it was positioned in. As a result, the wing parts 39 can be bent toward the bottom surface 29 of the groove 21, the bent parts 41 can be brought into contact with the bottom surface 29, and at the same time the through holes 47 can be placed against the bottom surface 29, making it easier to screw the fixing means into the bottom surface 29 and less likely to cause displacement of the hook body 13.

[0082] In addition, in this strap structure, a pair of wings 39 are provided extending from both longitudinal sides of the strap body 13, sandwiching the base plate 37. The strap fixing part 17 forms a triangular truss structure with the base plate 37 as its apex and is fixed to the bottom surface 29 by fastening the bent parts 41 of the tip ends 40 of the pair of wings 39 to the bottom surface 29 by fixing means. As a result, a support structure is formed between the pair of wings 39 and the bottom surface 29 of the groove 21, sandwiching the base plate 37, and the strap body 13 can be firmly fixed to the bottom surface 29.

[0083] Furthermore, in this structure of the hook, the hook body 13 may be configured to have an embedding portion 57 that hangs down from the underside 15. The embedding portion 57 is embedded together with the hook fixing portion 17 in the mortar 65 filled in the groove 21. Therefore, when the mortar 65 hardens, in addition to the fixation strength provided by the hook fixing portion 17 being fixed to the bottom surface 29, further fixation strength is obtained by the mortar adhering and integrating with the embedding portion 57. As a result, in addition to the hook fixing portion 17, the embedding portion 57 that hangs down from the underside 15 of the hook body 13 can also be embedded in the mortar, allowing the hook body 13 to be more firmly fixed to the bottom surface 29.

[0084] In the method for installing a shoelace according to this embodiment, a shoelace 23 having a shoelace fixing part 17 fixed to its underside 15 is used for installation. The shoelace fixing part 17 has a base part 37 fixed to the underside 15 and wings 39 extending from the base part 37. The sliding body 13 is fixed to the jamb 33. That is, the sliding body 13 is fixed by connecting the lower ends of the vertical frames 35 of the jamb 33. In the erection process, the jamb 33 is erected, so that the sliding body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21.

[0085] After the positioning of the shoelace body 13 is completed, in the bending process, the shank 53 of a tool 51 such as a screwdriver is inserted between the lower surface 15 and the wing 39. The shank 53 of the tool 51 presses the wing 39 downward, deforming it and bending it further until it contacts the bottom surface 29.

[0086] In the fixing step, the bent wing portions 39 are fixed, that is, fastened, to the bottom surface 29 by using fixing means 49 such as screws at the bent portions 41 formed at the extending tips of the wing portions 39 .

[0087] As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 29 of the groove 21 via the strap fixing portion 17 without using a welding device, that is, without using a firearm.

[0088] In the filler filling process, the mortar 65 of the hook body 13 forms a finished surface 67 flush with the floor surface 19, and as the mortar 65 is filled into the groove 21, at least a portion of the side of the hook body 13 excluding the top surface 11 and the hook fixing part 17 are embedded in the mortar 65 which is flush with the floor surface 19.

[0089] In this method of construction of the shim, the shim body 13 is firmly fixed to the bottom surface 29 of the groove 21 in a truss structure by the shim fixing parts 17 embedded in the mortar 65. The shim fixing parts 17 fixed to the shim body 13 are fixed to the bottom surface 29 by fixing means 49. Therefore, in this construction method of the shim, the shim body 13 can be fixed to the bottom surface 29 of the groove 21 with a simple structure without welding and without increasing the number of parts.

[0090] Furthermore, in the fastening member 55 for a string according to this embodiment, a wing portion 39 having a bent portion 41 is formed on the base portion 37 fixed to the underside 15 of the string body 13. In other words, the fastening member 55 for a string has a simple structure consisting of the base portion 37, the wing portion 39, and the tip portion 40, and is formed as a single component.

[0091] The base plate portion 37 of the strap fixing member 55 is fixed to the lower surface 15 of the strap body 13 by, for example, welding, and is integrated with the strap body 13 .

[0092] After the positioning of the shoelace body 13 is completed, the shank 53 of a tool 51 such as a screwdriver is inserted between the underside 15 and the wing 39. The shank 53 of the tool presses the wing 39 downward, deforming it and bending the tip 40 until it contacts the bottom surface 29.

[0093] The bent wing portions 39 are fixed to the bottom surface 29 by means of fixing means 49 such as screws at the bent portions 41 formed at the extending tips of the wing portions 39 and abutting against the bottom surface 29. As a result, the positioning of the chain body 13 is completed, and the chain body 13 is fixed to the bottom surface 29 of the groove 21 via the chain fixing members 55 without the use of a welding device, without fire.

[0094] The fixing member 55 for the lashing is embedded in the mortar 65, which is flush with the floor surface 19, along with at least a portion of the side of the lashing body 13 excluding the top surface 11, by filling the groove 21 with mortar 65, forming a finished surface 20 in which the mortar 65 is flush with the floor surface 19.

[0095] The fastening members 55 are embedded in the mortar 65, and thereby firmly fix the fastening body 13 to the bottom surface 29 of the trench 21 with a truss structure. Therefore, the fastening members 55 can fix the fastening body 13 to the bottom surface 29 of the trench 21 with a simple structure without welding and without increasing the number of parts.

[0096] Furthermore, in this fastener 55, the wings 39 can be bent toward the bottom surface 29, thereby connecting the underside 15 of the fastener body 13 to the bottom surface 29 via the wings 39. The metal wings 39 can be easily bent thanks to the bend guides 45 formed between the base plate 37 and the wings 39. The bend guides 45 can be, for example, slits, holes (intermittent or continuous), grooves, or perforated or recessed holes. Even if there is a difference between the underside 15 and the bottom surface 29 of the fastener body 13, by changing the bending angle of the wings 39, the tip 40 can abut against the bottom surface 29. Even if the bottom surface 29 is uneven, this difference can be absorbed and the underside 15 can be firmly fixed to the bottom surface 29. As a result, the wing portions 39 can be easily bent toward the bottom surface 29 of the groove 21 with the folding guide portions 45 provided between the base portion 37 and the wing portions 39 as the base and center of folding.

[0097] Furthermore, in this hanging fixture 55, a pair of wings 39 are provided extending from both longitudinal sides of the hanging body 13, sandwiching the base plate 37. When the bent portions 41 of the pair of wings 39 are fastened to the bottom surface 29 with screw fittings, the hanging fixture 17 forms a triangular truss structure with the base plate 37 as its apex, forming a support structure between the pair of wings 39 and the bottom surface 29, and is fixed in place. As a result, the pair of wings 39 can be fixed to the bottom surface 29 of the groove 21, sandwiching the base plate 37 between them, and can be firmly fixed to the bottom surface 29.

[0098] Therefore, according to the structure of the hook and the construction method of the hook of this embodiment, the hook 23 can be constructed without using a welding device, i.e., without fire, and completely fire-free construction of the three-sided frame 33 can be achieved.

[0099] Furthermore, by attaching the strap fixing member 55 according to this embodiment to the underside 15 of the strap body 13, it is possible to absorb variations in the depth of the bottom surface 29 of the groove 21 and support the strap body 13 on the bottom surface 29. After fastening, it forms a truss structure, which allows the strap body 13 to be firmly fixed to the bottom surface 29 without fire. [Explanation of symbols]
