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, so they are typically secured by welding. The three-sided frames that make up steel door frames, i.e., vertical frames, are secured to the building frame using a so-called fireless method, which does not require welding. However, it has been difficult to employ a fireless method equivalent to this construction method and structure for door frames. In other words, unlike the three-sided frames, door frames are secured at a level relative to the floor, and as mentioned above, the inside of the door frame is filled with mortar, making it difficult to secure with screws, and welding was therefore necessary. For this reason, if construction of the Kutsuzuri was to be made completely fireproof, it would be necessary to use a method that did not comply with the standard specifications of the Ministry of Land, Infrastructure, Transport and Tourism, namely, a method of retrofitting the Kutsuzuri. In this case, the structure would become complicated and the work would become cumbersome, making it an ineffective method.

[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 easily installed without firearms, a method of installing a shoe, and a fixing member for the shoe that can realize completely fire-free installation of the frame. [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 an upper surface 11, a chain fixing part 17 fixed to a lower surface 15 of the chain body 13, a groove 21 provided by cutting into a floor surface 19 and into which the chain body 13 is placed, and a filler 23 filled into the groove 21 with the upper surface 11 of the chain body 13 exposed, The strapping fixing part 17 includes a base 37 fixed to the lower surface 15, wings 39 extending from the base 37, fixing holes 43 drilled at the rear of the tips 41 of the wings 39, and bending guide parts 45 formed on both sides of the wings 39 across the fixing holes 43. The fastening member 51 is inserted into the fixing hole 43. the bottom The bend guide portion 45 is fixed to the bottom surface 33 at the position of the bend guide portion 45 by entering the bottom surface 33 .

[0007] In this chain structure, a chain fixing part 17 is fixed to the underside 15 of the chain body 13. The chain fixing part 17 is fixed to the underside 15 of the chain body 13, which faces the bottom surface 33 of the groove 21. The chain fixing part 17 has a base 37 that is fixed to the underside 15 of the chain body 13. The wings 39 are made of the same material as the base 37 and extend from the base 37 parallel to the underside 15. The sliding body 13 is fixed to, for example, a three-sided jamb. The three-sided jamb has a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame. The sliding body 13 is fixed by connecting the lower ends of the vertical frames 35 of the three-sided jamb. When the three-sided jamb is set in place, the sliding body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21. Once the positioning of the strap body 13 is complete, the strap fixing part 17 is bent by pressing down and deforming the tip 41 protruding from the side edge of the strap body 13 until the tip 41 of the wing part 39 abuts against the bottom surface 33. A fastening member 51 is inserted into the fixing hole 43 of the tip 41 of the downwardly bent wing 39. The fastening member 51 is inserted, for example, screwed, into the bottom surface 33. As the fastening member 51 is screwed into the bottom surface 33, the wing 39 is deformed until the fixing hole 43 contacts the bottom surface 33, and then the tip 41 is fixed approximately parallel to the bottom surface 33. At this time, the bending guide portions 45 formed on both sides of the wing 39 that sandwich the fixing hole 43 cause the inclined wing main body 57 and the tip 41 that deforms parallel to the bottom surface 33 to bend (bend) at the bending guide portions 45. In other words, the wing 39 bends along a straight line connecting the two bending guide portions 45 formed on both sides. As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 33 of the groove 21 via the strap fixing portion 17 without any fire. The groove 21 is filled with filler 23, so that at least a part 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 23 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 23, and is firmly fixed to the bottom surface 33 of the groove 21. The sheath fixing parts 17 have a simple structure consisting of a base 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 33 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, The further the fastening member 51 penetrates, the more it follows the bottom surface 33 and is fixed.

[0009] In this sheath structure, as the fastening member 51 advances further into the bottom surface 33 , the bend guide portion 45 deforms in accordance with the bottom surface 33 and is fixed to the bottom surface 33 .

[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 wing portions 39 extend at an acute angle to the longitudinal direction of the hook body 13.

[0011] In this structure of the sheath, the wings 39 are attached to the sheath body 13 at an acute angle, for example, a 45° angle in plan view, relative to the longitudinal direction of the sheath body 13. This allows the wings 39 to have a greater extension length than when they are attached perpendicular to the longitudinal direction of the sheath body 13. This allows the wings 39 to make contact with the ground in shallow grooves 21 as well as deep grooves 21, compared to when they are attached perpendicular to the sheath body 13. Furthermore, by inclining the wing portions 39, when the filler 23 is filled from the side of the shelving body 13, the flow resistance of the filler 23 is reduced compared to when the wing portions 39 are attached in a direction perpendicular to the longitudinal direction of the shelving body 13. In other words, the filler 23 can be filled more easily, and the filling operation can be carried out smoothly.

[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 base portion 37 is characterized in that a folding guide portion 49 is provided to facilitate folding of the wing portion 39 in a direction away from the lower surface 15 .

[0013] In this sheath structure, a folding guide portion 49 is provided between the wing main body 57 and the base 37. The folding guide portion 49 is a portion that facilitates folding of the base 37 and the wing main body 57, such as a single elongated hole (such as a slit), multiple holes (intermittent or continuous), grooves 21 that are narrowed in the thickness direction, or perforations. The wing 39 is easily folded with the wing main body 57 tilting downward at the folding guide portion 49 relative to the base 37 fixed to the underside 15 of the sheath body 13.

[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, The bending guide portions 45 are characterized by being formed by notches on both edges of the wing portions 39 in the width direction.

[0015] In this chain structure, bending guides 45 are formed from both widthwise edges of wing 39. The bending guides 45 are, for example, recesses 53 formed by cutting out both widthwise edges of wing 39. As described above, bending guides 45 are formed on both sides of wing 39 that sandwich fixing hole 43. Wing 39 is inclined downward relative to base 37 and is deformed until tip 41 contacts bottom surface 33 of groove 21. When tip 41 contacts bottom surface 33, tip 41 and wing main body 57 are still flat. In this state, when fastening member 51 inserted through fixing hole 43 is screwed into bottom surface 33 of groove 21, fixing hole 43 is tightened against bottom surface 33, and tip portion 41 bends at the boundary with wing main body 57. At this time, bend guide portion 45 of tip portion 41 becomes a weak portion, and tip portion 41 is bent (flexed) at the position of bend guide portion 45. This prevents tip portion 41 and wing main body 57 from deforming in unexpected positions. Wing 39 bends at recesses 53 formed by cutting out both edges in the width direction, forming corners at the ends of wing body 57. This makes it easier for inclined wing body 57 to absorb the unevenness of bottom surface 33, which is an uneven surface, compared to when the ends are linear, allowing for stable contact without slipping.

[0016] The structure of the splice according to claim 6 of the present invention is the structure of the splice according to claim 5, The bending guide portion 45 is characterized in that a notch central axis 55 is cut in such a manner that it is inclined with respect to the extending direction of the wing portion 39 .

[0017] In this structure of the sheath, the bending guide portion 45 is cut with the notch central axis 55 inclined relative to the extension direction of the wing portion 39. For example, if the bending guide portion 45 is a recess 53, the recess 53 is cut from the tip side. The notch central axis 55 of the recess 53 is inclined at a predetermined angle relative to the extension direction of the wing portion 39. As described above, the wing portion 39 can be configured to extend at a predetermined angle, for example, 45°, relative to the longitudinal direction of the sheath body 13 in a plan view. The recess 53 is, for example, a U-shaped notch formed by cutting an oval along its minor axis. In this case, the notch central axis 55 of the recess 53 is the direction of the major axis of the oval. When the tip 41 of this U-shaped recess 53 is bent parallel to the bottom surface 33 by screwing in the fastening member 51, the front half of the U-shaped recess 53, which is defined by the central axis 55 of the U-shaped cutout, becomes parallel to the bottom surface 33 together with the tip 41. On the other hand, the rear half of the U-shaped recess 53 remains as pointed ends 59 on both sides of the wing body 57, which slopes downward from the underside 15 of the hook body 13. When the fastening member 51 is screwed into the bottom surface 33, the tip 41 of the wing body 57 is pulled toward the bottom surface 33, and this pointed end 59 bites into the bottom surface 33. This allows the end of the wing body 57 to land firmly on the bottom surface 33 without being affected by the unevenness of the bottom surface 33, which tends to be an uneven surface.

[0018] The structure of the splice according to claim 7 of the present invention is the structure of the splice according to any one of claims 1 to 6, The strap fixing portion 65 is characterized in that it is provided with a guide 67 for positioning the wing portion 39 relative to the strap body 13 .

[0019] In this chain structure, the chain fixing part 65 has a guide 67 for positioning the wing 39 relative to the chain body 13. The chain fixing part 65 is fixed to the chain body 13, for example, by welding at a factory. The guide 67 can be, for example, a guide recess formed on both edges of the wing 39. In this guide recess, an imaginary line 73 connecting the bending guide parts 45 formed on the opposite side edges is inclined at an angle of 45° with respect to the center line 75 of the wing 39. Therefore, when fixing the wing portion 39 to the underside 15 of the sheath body 13, the wing portion 39 can be easily positioned at an angle of 45° relative to the longitudinal direction of the sheath body 13 in a plan view by aligning the bending guide portion 45 and the guide recess with the edge of the sheath body 13.

[0020] The method for constructing a floor board according to claim 8 of the present invention comprises the steps of: a step of inserting the shoe body 13 into the groove 21 and positioning it; a bending step of bending wing portions 39 extending from the base 37 of the strap fixing portion 65, the base 37 of which is fixed to the underside 15 of the strap body 13, so that the tip portions 41 of the wing portions 39 abut against the bottom surface 33 of the groove 21; a fixing process in which a fastening member 51 is inserted into a fixing hole 43 drilled at the rear of the tip portion 41 and is inserted into a bottom surface 33 of the groove 21 to deform the tip portion 41, and the further the fastening member 51 is inserted, the more it follows the bottom surface 33 and is fixed to the bottom surface 33; a filler filling step of filling the groove 21 with filler 23 with the upper surface 11 of the strap body 13 exposed, and embedding at least a portion of the side surface of the strap body 13 excluding the upper surface 11 and the strap fixing part 17; The present invention is characterized by comprising:

[0021] In this method of installing a shoe slide, a shoe slide 25 to which a shoe slide fixing part 17 is fixed is used for installation. The shoe slide fixing part 17 has a base 37 fixed to the underside 15 of the shoe slide main body 13, with wings 39 extending parallel to the underside 15. The shoe slide main body 13 is fixed to, for example, a three-sided jamb. 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. In an opening in, for example, the building frame to which the three-sided jamb 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 installation process, the three-sided jamb is installed, and 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 strap body 13 is completed, the tip 41 of the strap fixing part 17 protruding from the side edge of the strap body 13 is pressed downward in the bending process, and the wing part 39 is deformed downward. The tip 41 of the wing part 39 deformed downward is brought into contact with the bottom surface 33. In the fixing process, fastening member 51 is inserted into fixing hole 43 provided behind tip portion 41 of wing portion 39, which has been bent with tip portion 41 in contact with bottom surface 33. As fastening member 51 is screwed into bottom surface 33, tip portion 41 of wing portion 39 is bent at bend guide portions 45 formed on both sides of fixing hole 43 as the screwing progresses, and is fixed approximately parallel to bottom surface 33. In other words, tip portion 41 deforms along a straight line connecting two bend guide portions 45 formed on both sides of wing portion 39. The end of wing portion 39's wing body 57, which is rearward of tip portion 41, is drawn toward tip portion 41, which is fastened to bottom surface 33. As a result, wing body 57 bites into bottom surface 33, firmly contacts bottom surface 33, and becomes immobile. As a result, the strap body 13, which has been positioned, is completely fixed to the bottom surface 33 of the groove 21 via the strap fixing portion 17. In the filler filling process, filler 23 is filled into grooves 21 of the hook body 13, forming a filler-finished surface that is flush with the floor surface 19. The filler 23 embeds at least a portion of the side surface of the hook body 13, excluding the top surface 11, and the hook fixing part 17. At this time, the hook body 13 is prevented from lifting up from the bottom surface 33 by the hook fixing part 17, which is fixed to the bottom surface 33. In this method of installing a string, the string body 13 forms a truss structure with the string fixing parts 17 embedded in the filler 23, and is firmly fixed to the bottom surface 33 of the groove 21. The string fixing parts 17, which are fixed to the string body 13, are fixed to the bottom surface 33 with fastening members 51. Therefore, in this method of installing a string, welding is not performed, that is, the installation is performed without firearms, and welding equipment is not required, and the string body 13 can be fixed to the bottom surface 33 of the groove 21 with a simple structure and without increasing the number of parts.

[0022] The ninth aspect of the present invention provides a fastening member 47 for a string, which is fixed to the underside 15 of a string body 13 having an upper surface 11, and is fixed to the bottom surface 33 of a groove 21 formed by cutting a floor surface 19, and is embedded in a filler 23 that fills the groove 21 with the upper surface 11 of the string body 13 exposed, It is characterized by comprising a base 37 fixed to the lower surface 15, wing portions 39 inclined at an acute angle to the longitudinal direction of the sheath body 13 and extending from the base 37 parallel to the lower surface 15, a fixing hole 43 drilled behind a tip portion 41 protruding from the side edge of the sheath body 13, and bending guide portions 45 formed on both sides of the wing portions 39 sandwiching the fixing hole 43.

[0023] In this strap fixing member 47, wings 39 having a tip 41 are formed on a base 37 fixed to the underside 15 of the strap body 13. In other words, the strap fixing member 47 has a simple structure consisting of the base 37, wings 39, and tip 41, and is formed as a single component that is attached and fixed to the strap body 13. The base 37 of the strap fixing member 47 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 strap body 13 is completed, the tip 41 of the strap fixing member 47 protruding from the side edge of the strap body 13 is pressed downward, and the wing 39 is deformed downward. The tip 41 of the wing 39 deformed downward is in contact with the bottom surface 33. Wing 39 is bent with tip 41 in contact with bottom surface 33, and fastening member 51 is inserted into fixing hole 43 provided behind tip 41. When fastening member 51 is screwed into bottom surface 33, tip 41 of wing 39 is bent at bending guide portions 45 formed on both sides of fixing hole 43 and fixed approximately parallel to bottom surface 33. The end of wing main body 57 of wing 39, which is rearward of tip 41, is drawn toward tip 41 which is fastened to bottom surface 33. As a result, wing main body 57 bites into bottom surface 33, firmly contacts bottom surface 33, and becomes immobile. As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 33 of the groove 21 by the strap fixing member 47 without any fire. The fixing member 47 for the hook is embedded in the filler 23 which is flush with the floor surface 19 by filling the groove 21 with the filler 23, together with at least a portion of the side surface of the hook body 13 excluding the top surface 11. The strap fixing member 47 has a truss structure that supports the strap body 13 between itself and the bottom surface 33 of the groove 21, firmly fixing it in place. Therefore, the strap fixing member 47 does not require welding, has a simple structure, and can fix the strap body 13 to the bottom surface 33 of the groove 21 without increasing the number of parts.

[0024] The fixing member 47 for hanging shoes according to claim 10 of the present invention is the fixing member 47 for hanging shoes according to claim 9, The base portion 37 is characterized in that a folding guide portion 49 is provided to facilitate folding of the wing portion 39 in a direction away from the lower surface 15 .

[0025] In this threading fixing member 47, the portion between the wing main body 57 and the base 37 forms the folding guide portion 49. The folding guide portion 49 is a portion that facilitates folding between the base 37 and the wing main body 57, such as a single elongated hole (such as a slit), multiple holes (intermittent or continuous), grooves 21 that are narrowed in the thickness direction, or perforations. The wing 39 is easily folded relative to the base 37 fixed to the underside 15 of the threading body 13, with the wing main body 57 tilting downward at the folding guide portion 49.

[0026] The fixing member 47 for hanging shoes according to claim 11 of the present invention is the fixing member 47 for hanging shoes according to claim 10, The bending guide portions 45 are characterized by being recesses 53 formed by cutting out both edges of the wing portions 39 in the width direction.

[0027] In this fastening member 47, bending guide portions 45 are formed from both edges of the wing portions 39 in the width direction. The bending guide portions 45 are recesses 53 formed by cutting out both edges of the wing portions 39 in the width direction. As described above, the bending guide portions 45 are formed on both sides of the wing portions 39 that sandwich the fixing hole 43. The wing portions 39 are inclined downward relative to the base portions 37 and are deformed until the tip portions 41 contact the bottom surfaces 33 of the grooves 21. When the tip portions 41 contact the bottom surfaces 33, the tip portions 41 and the wing portions main bodies 57 are still flat. In this state, when fastening member 51 inserted through fixing hole 43 is screwed into bottom surface 33 of groove 21, fixing hole 43 is tightened against bottom surface 33, and tip portion 41 bends at the boundary with wing main body 57. At this time, bend guide portion 45 of tip portion 41 becomes a weak portion, and tip portion 41 is bent (flexed) at the position of bend guide portion 45. This prevents tip portion 41 and wing main body 57 from deforming in unexpected positions. Wing 39 bends at recesses 53 formed by cutting out both edges in the width direction, forming corners at the ends of wing body 57. This makes it easier for inclined wing body 57 to absorb the unevenness of bottom surface 33, which is an uneven surface, compared to when the ends are linear, allowing for stable contact without slipping.

[0028] The fixing member 47 for hanging shoes according to claim 12 of the present invention is the fixing member 47 for hanging shoes according to claim 11, The recess 53 is characterized in that a notch central axis 55 is inclined at a predetermined angle with respect to the extending direction of the wing portion 39 and is cut from the tip end side.

[0029] In this threading fixture 47, a recess 53 is cut from the tip end side. The recess 53 has a notch central axis 55 inclined at a predetermined angle with respect to the extension direction of the wing portions 39. As described above, the wing portions 39 extend at an angle of 45° with respect to the longitudinal direction of the threading body 13 in a plan view. The recess 53 is, for example, a U-shaped notch formed by cutting an oval along its minor axis. In this case, the notch central axis 55 of the recess 53 is in the direction of the major axis of the oval. When the tip 41 of this U-shaped recess 53 is bent parallel to the bottom surface 33 by screwing in the fastening member 51, the front half of the U-shaped recess 53, which is defined by the central axis 55 of the U-shaped cutout, becomes parallel to the bottom surface 33 together with the tip 41. On the other hand, the rear half of the U-shaped recess 53 remains as pointed ends 59 on both sides of the wing body 57, which slopes downward from the underside 15 of the hook body 13. When the tip 41 of the wing body 57 is screwed into the bottom surface 33 by fastening the fastening member 51, the tip 41 is pulled toward the bottom surface 33, and the pointed end 59 bites into the bottom surface 33. This allows the end of the wing body 57 to land firmly on the bottom surface 33 without being affected by the unevenness of the bottom surface 33, which tends to be an uneven surface.

[0030] The fixing member 69 for hanging shoes according to claim 13 of the present invention is the fixing member 69 for hanging shoes according to any one of claims 9 to 12, The wing portion 39 is characterized in that a guide 67 for positioning the slipper body 13 is provided.

[0031] This strap fixing member 69 has guides 67 for positioning the wing portions 39 relative to the strap body 13. The strap fixing member 69 is fixed to the strap body 13, for example, by welding at a factory. The guides 67 can be guide recesses formed on both edges of the wing portions 39. In this guide recess, an imaginary line 73 connecting the bending guide portions 45 formed on the opposite side edges is inclined at an angle of 45° with respect to the center line 75 of the wing portions 39. Therefore, when fixing the wing portion 39 to the underside 15 of the sheath body 13, the wing portion 39 can be easily positioned at an angle of 45° relative to the longitudinal direction of the sheath body 13 in a plan view by aligning the bending guide portion 45 and the notch with the edge of the sheath body 13.

[0032] The fixing member for hanging a shoe according to claim 14 of the present invention is the fixing member for hanging a shoe according to any one of claims 9 to 13, The sheaths are configured in pairs in the width direction of the sheath body 13, with their respective bases 37 closely adjacent to each other and fixed to the underside 15, and their respective tip portions 41 protruding outward from the side edges.

[0033] These chain fixing members are arranged in pairs, one on each side of the chain body 13 in the width direction, with their respective tips 41 protruding from the side edges. The bases 37 fixed to the underside of the chain body 13 are fixed in close proximity without interfering with each other. For example, if the chain body 13 is narrow, such as when the length of the chain fixing member itself is longer than the width of the chain body 13, the bases 37 can be arranged on either side of a line perpendicular to the longitudinal direction of the chain body 13. This makes it less likely that the pair of chain fixing members will interfere with each other when fixed to the chain body 13, and they can be used with chain bodies 13 of various widths and lengths. [Effects of the Invention]

[0034] According to the structure of the lashing described in claim 1 of the present invention, the lashing can be constructed without fire by simply bending the wing portion downward and fixing the tip portion to the bottom of the groove with a fastening member. In other words, the construction can be completed without using any welding equipment. This eliminates the need for complicated work processes such as preparing, transporting, and removing the welding equipment, thereby simplifying the construction and reducing the construction time.

[0035] According to the structure of the shoe according to claim 2 of the present invention, as the fastening member advances, the bend guide portion deforms in accordance with the bottom surface, making it possible to fix the shoe to the bottom surface.

[0036] According to the structure of the shoe according to claim 3 of the present invention, the wing length can be made long, the adjustment range to the bottom surface can be increased, and the filler can be easily introduced.

[0049] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [First embodiment] FIG. 1 is a perspective view showing the structure of a hook according to the first embodiment. The structure of the hook in this embodiment comprises a hook body 13 having a long, strip-shaped upper surface 11, a hook fixing part 17 fixed to the lower surface 15 of the hook body 13, a groove 21 formed by cutting into the floor surface 19 with a width wider than the width of the hook body 13, and the hook body 13 is placed inside, and a filler 23 (see Figure 2) filled into the groove 21 with the upper surface 11 of the hook body 13 exposed.

[0050] The filler 23 may be mortar, concrete, or an adhesive anchor such as Chemical Anchor (registered trademark), but in the following embodiments, the filler 23 will be described as mortar.

[0051] The shoe slide 25 is roughly composed of a shoe slide main body 13 and a shoe slide fixing part 17. In this embodiment, the shoe slide main body 13 has a cross section perpendicular to the longitudinal direction, which has a horizontal L-shape with an upwardly sloping step 29 bent from one widthwise side of a band plate part 27 having a lower surface 15. The step 29 is closed by an upright piece 31 that rises from the band plate part 27, forming a trapezoidal cylindrical crossbar part. The crossbar part rises in a step from the upper surface 11 of the band plate part 27.

[0052] The shape of the slider body 13 is not limited to this. The slider body 13 only needs to have a strip portion 27 with at least an upper surface 11 and a lower surface 15. Suitable materials for the slider body 13 include, for example, steel, stainless steel, and aluminum. The lower surface 15 of the strip portion 27 of the slider body 13 is a smooth rectangle. The slider body 13 has a filler 23 filled between the lower surface 15 and the bottom surface 33 of the groove 21, and the crosspiece at the bottom of the entrance protrudes slightly from the floor as a step.

[0053] The shoe slide 25 is fixed to a three-sided frame and transported to the construction site. The three-sided frame is made up of a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame (not shown). The shoe slide 25 is installed with the shoe slide body 13 connecting the lower ends of the vertical frames 35 of the three-sided frame. In other words, the installation of the shoe slide 25 turns the three-sided frame into a square frame (four-sided frame).

[0054] The hanging fixture 17 comprises a base 37 fixed to the underside 15, wings 39 extending from the base 37 parallel to the underside 15, a fixing hole 43 drilled at the rear of a tip 41 of the wing 39 protruding from the side edge of the hanging body 13, and bending guide portions 45 formed on both sides of the wing 39 that sandwich the fixing hole 43. The hanging fixture 47 shown in Figure 1 shows the shape after being bent during on-site construction.

[0055] The strap fixing portion 17 is formed separately from the strap body 13. The strap fixing portion 17 is formed in the shape of a strip. The strap fixing portion 17 is made of, for example, steel. Steel is a suitable steel material. The thickness of the strap fixing portion 17 can be, for example, 0.8 mm, 1.0 mm, 1.2 mm, 1.6 mm, or 2.3 mm. The strap fixing portion 17 is formed into a flat rectangular shape by sheet metal processing or the like. The base end of the strap fixing portion 17 in the longitudinal direction becomes a base portion 37 in the shape of a substantially square flat plate. Base fixing holes 48 through which rivets or the like can be inserted are drilled in the base portion 37. The base portion 37 may ultimately be formed into a semicircular shape by chamfering the rear end corners. The tip 41 of the lathe fixing part 17, opposite the base 37, is pointed into a triangular shape. The base 37 is fixed to the underside 15 of the lathe body 13 by, for example, screws, rivets, or welding. As a result, the lathe fixing part 17 and the lathe body 13 can be transported to the construction site together.

[0056] The hanging fixture 17 is provided with a folding guide portion 49 at the boundary between the base 37 and the wing portions 39. The folding guide portion 49 facilitates folding of the wing portions 39 in a direction away from the underside 15 with respect to the base 37. The hanging fixture 17 forms a triangular truss and is therefore formed of a steel plate or the like having a predetermined thickness. Therefore, by providing the folding guide portion 49, the hanging fixture 17 makes it easy to fold the wing portions 39 at the boundary with the base 37. The folding guide portion 49 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.

[0057] The fastening member 51 of the hanging fixture 17 is inserted into the fixing hole 43. The fastening member 51 may be, for example, a concrete screw or a concrete nail. When the fastening member 51 inserted into the fixing hole 43 is screwed into the bottom surface 33, the hanging fixture 17 has its base 37 fixed to the underside 15 of the hanging body 13. The fastening member 51 is inserted into the fixing hole 43 and screwed into the bottom surface 33, so that the tip 41 is bent at the position of the bending guide portion 45 and fixed to the bottom surface 33. The fastening member 51 may be manually screwed into the bottom surface 33 using a tool such as a screwdriver. In this case, a pilot hole may be pre-drilled in the bottom surface 33. The fastening member 51 may also be screwed into the bottom surface 33 in one go using a tool such as an impact drill.

[0058] The above-mentioned folding guide portion 49 is referred to as the "folding guide portion 49" because it directly presses down on and bends the wing portion 39. In contrast, the bending guide portion 45 is referred to as the "bending guide portion 45" because it is indirectly bent by the entry of the fastening member 51, for example, by screwing, to distinguish between the two.

[0059] FIG. 2 is a cross-sectional view of the sheave 25 fixed in the groove 21 in a direction perpendicular to the longitudinal direction. The pair of strap fixing parts 17 are fixed to the strap body 13 in pairs so that their tip ends 41 protrude from both sides of the strap body 13 in the width direction. The strap fixing parts 17 are bent at the bending guide parts 49 so that each wing 39 moves away from the underside 15 of the strap body 13. The tip ends 41 of the wing parts 39 contact the bottom surface 33 of the groove 21 before the fastening members 51 are inserted into the fixing holes 43. In other words, the fixing holes 43 also serve as positioning means when screwing the fastening members 51 into the bottom surface 33. In the strap structure, the strap fixing parts 17, with their tip ends 41 protruding from both sides of the strap body 13 in the width direction, are fixed to the bottom surface 33. As a result, the strap fixing portion 17 can fix the strap body 13 to the bottom surface 33 of the groove 21 with an equal fixing force from both sides of the strap body 13 in the board width direction.

[0060] FIG. 3 is a view taken along the line AA in FIG. The structure of the sling is such that the wing portions 39 extend at a 45° angle relative to the longitudinal direction of the sling body 13 in a plan view. The width of the sling body 13 can be narrow or wide. Considering that the sling fixture 17 is attached at a 45° angle, by dividing it into two and changing the attachment position of the base 37, it is possible to make the tip portions 41 protrude in the same manner from both edges of the sling body 13. The sling fixture 17 has a point-symmetrical shape that allows identically shaped components to be rotated (orientation changed) and attached for versatility and commonality during mass production. The pair of rotated sling fixtures 17 are offset, for example, by approximately 10 mm in the longitudinal direction of the sling body 13. The pair of sling fixtures 17 are provided at multiple locations according to the length of the sling body 13. As an example, the distance between the strap fixing parts 17 in the direction along the strap body 13 is within about 500 mm, and they are provided at positions about 150 mm from both ends of the strap body 13 in the longitudinal direction.

[0061] FIG. 4 is a plan view of the fastening member 47 for hanging. The bending guide portions 45 may be recesses 53 formed by cutting out both edges of the wing portions 39 in the width direction.

[0062] The recess 53 is cut from the tip end side with a notch central axis 55 inclined at a predetermined angle θ with respect to the extension direction a of the wing portion 39. The predetermined angle θ can be, for example, 45°. The recess 53 is, for example, a U-shaped notch formed by cutting an oval along its minor axis. In this case, the notch central axis 55 of the recess 53 is the direction of the major axis of the oval.

[0063] Next, a modified example of the structure of the hook according to the first embodiment will be described.

[0064] FIG. 5 is a plan view showing the structure of a modified version of the hook when the hook body 13 is narrow. When the width of the string body 13 is narrow, the pair of string fixing parts 17 can be arranged on both sides of a line segment perpendicular to the longitudinal direction of the string body 13. This makes it possible for the pair of string fixing parts 17 to be less likely to interfere with each other when fixed to the string body 13.

[0065] FIG. 6 is a plan view of a modified example of a fastening member 47 for hanging in which the bending induction portion 45 is rectangular. The bending guide 45 can be a rectangular recess 53. By making the recess 53 rectangular, an acute pointed end 59 can be formed at the end of the wing body 57 after the tip 41 is bent. This allows the hanging fixture 17 to bite into the bottom surface 33 well. Furthermore, although not shown, this recess 53 may be configured to be formed by a cutout having a shape such as a V-shape in addition to the U-shape or square shape described above, and is preferably formed from both edges of the width direction of the wing portion 39, and cut from the tip side with the cutout central axis 55 inclined at a predetermined angle θ with respect to the extension direction a of the wing portion 39 as described above.

[0066] FIG. 7 is a plan view of a fastening member 47 for hanging according to a modified example in which the bending induction portion 45 is a constricted portion. The bending guide portion 45 can be formed by a constricted portion 61. By using the constricted portion 61 to narrow the width, both sides of the fixing hole 43 are formed narrower than the width of the wing portion 39 and continue to the tip portion 41, and the bending guide portion 45 on both sides of the fixing hole 43 can be formed longer than the recess 53 described above, making it easy to bend when screwed in by the fastening member 51. In addition, there is no sharp pointed portion 59 that will dig into the bottom surface 33, which improves safety during transportation and operation.

[0067] FIG. 8(a) is a plan view of a modified example of a fastening member 47 for hanging in which the bending guide portion 45 is a thin portion 63, and (b) is a side view of (a). The folding guide portion 49 and the bending guide portion 45 can be formed as a thin-walled portion 63. The thin-walled portion 63 reduces the bending strength of the hanging fixing portion 17, suppressing a decrease in strength compared to a notch, and makes it easier to bend between the wing portion 39 and the tip portion 41 at this weak portion.

[0068] Next, a method for installing the kutsuzuri 25 will be described.

[0069] FIG. 9 is a diagram illustrating the procedure of the erection process in the construction method of the shoe slide 25. The construction method of the shoelace 25 according to this embodiment includes a chipping process, a setting process, a bending process, a fixing process, and a filler filling process.

[0070] In the chipping process, the floor surface 19 is chipped to form a groove 21. The groove 21 is formed with a width greater than the width of the concrete block body 13. The sides of the groove 21 are scraped with the blade of a cutter (concrete cutter), resulting in a relatively smooth, approximately vertical surface. On the other hand, the bottom surface 33 of the groove 21 is created by chipping away the surface with a chisel or other tool, a so-called chipping process. As a result, the chipped bottom surface 33 is uneven and has many projections and depressions. In other words, the bottom surface 33 is an uneven surface. The groove 21 is formed with a width greater than the width of the vertical frame 35 of the three-sided jamb. The concrete block body 13 is positioned so that the top surface 11 of the concrete block body 13 is flush with the floor surface 19 or protrudes approximately 3 mm from the floor surface 19. The groove 21 is formed with a depth sufficient to provide a space below the concrete block body 13 into which mortar 23 can flow, i.e., a filler introduction section.

[0071] In the erection process, the slide 25 is attached to the frame and erected. The frame is made up of a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame (not shown). The slide 25 is installed by connecting the lower ends of the vertical frames 35 of the frame. In other words, the frame becomes a square frame (four-sided frame) with the slide 25 attached. In the erection process, the frame with the slide 25 attached is erected so that the slide body 13 is positioned in a predetermined position in the groove 21. In other words, the frame and slide body 13 are fixed to the frame (not shown) at the predetermined, positioned positions. In this state, the tip 41 of the slide fixing part 17 of the slide body 13 protrudes from both sides in the width direction.

[0072] FIG. 10 is a view taken along the arrow BB in FIG. 9, illustrating a bending step in the method of constructing the shoelace 25. In FIG. In the bending process, the wing portions 39 extending from the base portion 37 of the strap fixing portion 17, the base portion 37 of which is fixed to the underside 15 of the strap body 13, are pressed and bent so that the tip portions 41 of the wing portions 39 abut against the bottom surface 33 of the groove 21. This pressing and bending is facilitated by the provision of the bending guide portion 49, which allows the tip portions 41 to contact the bottom surface 33.

[0073] FIG. 11 is a diagram illustrating the procedure of the fixing step in the method of installing the shoelace 25. In the fixing process, fastening member 51 is inserted into fixing hole 43 formed at the rear of tip portion 41 that is in contact with bottom surface 33 and inserted into bottom surface 33 of groove 21. For example, if fastening member 51 is a screw or the like, it is screwed into bottom surface 33 of groove 21 with tool 81 such as a screwdriver or impact drill.

[0074] FIG. 12 is a diagram illustrating the procedure after the fixing step in the construction method of the shoelace 25 is completed. The hanging fixture 17 is fixed by threading the fastening member 51 inserted into the fixing hole 43 into the bottom surface 33, and deforming the tip 41 by tightening it so that it is parallel to the bottom surface 33. The angle of the wing 39 of the hanging fixture 17 from the bottom surface 33 is about 33°, at which the tip 41 touches the ground, and then bends at an angle of about 45°, and the pointed end 59 of the wing main body 57 bites into the bottom surface 33.

[0075] Although the bottom surface 33 of the groove 21 is formed during the chipping process, it is not smooth; rather, it is excavated using an electric pick or drill, resulting in a discontinuous, uneven surface, or so-called uneven surface. This causes variations in the distance from the shelving body 13, i.e., the distance between the underside 15 of the shelving body 13 and the bottom surface 33. However, by inserting the pointed end 59 protruding from the end of the wing body 57 into the uneven surface, this variation can be absorbed, fixing the end of the wing body 57 and firmly securing the underside 15 to the bottom surface 33. In other words, during the fixing process, the more the fastening member 51 penetrates the bottom surface 33, the more it bends and fixes to the condition of the bottom surface 33, i.e., the shape of the uneven bottom surface 33. The inclination angle of the wing body 57 adjusts the distance between the underside 15 and the uneven bottom surface 33, resulting in an interposed state on both sides. This interposed state supports the height of the sheath body 13 relative to the bottom surface 33, prevents the sheath body 13 from sinking, and also prevents the sheath body 13 from floating up in the subsequent filler filling process.

[0076] In the above-described fitting process, the slider 25 may be placed in the groove 21 without being connected to the jamb. That is, only the slider 25 is placed in the groove 21, and the bending process is then performed. In this case, after the chipping process, the fitting process involves carrying the slider 25 into the groove 21, and temporarily placing a support member (not shown) of a predetermined shape, such as a block, between the bottom surface 33 and the underside 15 of the slider body 13. The slider 25 is then placed in the groove 21 in a state where it is suspended above the bottom surface 33 of the groove 21. The support members may be, for example, multiple pieces, and are arranged at a predetermined distance in the longitudinal direction of the slider 25 so that each support member does not interfere with the slider fixing portion 17. This state results in a gap below the slider 25 (see FIG. 10), and the bending process begins from this suspended state. In the bending process, the tip 41 of the wing 39 is bent and pressed against the bottom surface 33 of the groove 21 in the same manner as described above, and is then grounded. After that, the wing 39 is fixed to the bottom surface 33 with the fastening members 51, and the support members are then removed. That is, the erection process involves using the support members to temporarily levitate the sheave 25 within the groove 21. When temporarily levitating the sheave 25, it is preferable to adjust the height and horizontal level of the sheave 25.

[0077] In the filler filling process, mortar 23, which is a filler, is filled into the groove 21 in which the baseplate body 13 is placed, so as to form a finished surface that is flush with the floor surface 19. The mortar 23 is embedded in 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 baseplate fixing parts 17 are also embedded in the mortar 23 at the same time. The mortar 23 filled into the groove 21 is hardened while in close contact with the bottom surface 15 of the baseplate body 13 and the baseplate fixing parts 17. After curing for a predetermined time, the mortar 23 hardens, embedding the baseplate fixing parts 17 and at least a portion of the side surface of the baseplate body 13, excluding the top surface 11, and the mortar 23 and the baseplate body 13, thereby completing the construction of the baseplate 25.

[0078] 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 47. The strap fixing member 47 can be attached to the underside 15 of various shapes of strap bodies 13 by attachment means such as welding, screwing, or fastening.

[0079] This running fixture 47 fixes the underside 15 of a running body 13, which has a long, strip-shaped upper surface 11, to the bottom surface 33 of a groove 21 cut into the floor surface 19 with a width wider than the width of the running body 13. The running fixture 47 is embedded in mortar 23 that fills the groove 21 with the upper surface 11 of the running body 13 exposed. Similar to the running fixture 17, the running fixture 47 comprises a base 37 fixed to the underside 15, wings 39 that extend from the base 37 parallel to the underside 15 and incline at a 45° angle with respect to the longitudinal direction of the running body 13, a fixing hole 43 drilled behind a tip 41 that protrudes from the side edge of the running body 13, and bend guides 45 formed on both sides of the wings 39 that sandwich the fixing hole 43.

[0080] The strapping fixing member 47 is provided with a folding guide portion 49 that facilitates folding of the wing portion 39 in a direction away from the lower surface 15 relative to the base portion 37 .

[0081] Furthermore, the strap fixing member 47 has the bending guide portions 45 each being a recess 53 formed by cutting out both edges of the wing portion 39 in the width direction.

[0082] Furthermore, the recess 53 of the fastening member 47 for hanging may be cut from the tip end side with the notch central axis 55 inclined at a predetermined angle θ with respect to the extending direction a of the wing portion 39 .

[0083] Next, the operation of the above-described configuration will be described.

[0084] In the structure of the strap according to this embodiment, the 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 of the strap body 13, which faces the bottom surface 33 of the groove 21. The strap fixing part 17 has a base 37 that is fixed to the underside 15 of the strap body 13. The wings 39 are made of the same material as the base 37 and extend from the base 37 parallel to the underside 15.

[0085] The sliding body 13 is fixed to, for example, a three-sided jamb. The three-sided jamb has a pair of parallel, spaced-apart vertical frames 35 whose upper ends are connected by an upper frame. The sliding body 13 is fixed by connecting the lower ends of the vertical frames 35 of the three-sided jamb. When the three-sided jamb is set in place, the sliding body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21.

[0086] Once the positioning of the hook body 13 is complete, the hook fixing portion 17 is bent by pressing down the tip 41 protruding from the side edge of the hook body 13, causing the wing portion 39 to be deformed (bent) at the bending position Pb (see Figure 4) relative to the base 37 until the tip 41 of the wing portion 39 abuts against the bottom surface 33.

[0087] A fastening member 51 is inserted into the fixing hole 43 of the tip 41 of the downwardly bent wing 39. The fastening member 51 is screwed into the bottom surface 33. As the fastening member 51 is screwed into the bottom surface 33, the wing 39 deforms until the fixing hole 43 contacts the bottom surface 33, and then the tip 41 is fixed in place so that it is approximately parallel to the bottom surface 33. At this time, the wing 39 bends (flexes) at a bending position Pk (see FIG. 4 ) that connects the inclined wing main body 57 and the tip 41, which deforms parallel to the bottom surface 33, due to the bending guide portions 45 formed on both sides of the wing 39 that sandwich the fixing hole 43. In other words, the wing 39 bends along a straight line connecting the two bending guide portions 45 formed on both sides.

[0088] As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 33 of the groove 21 via the strap fixing portion 17 without any fire.

[0089] The hook body 13 is filled with a filler 23 such as mortar in the groove 21, and 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 filler 23, which is flush with the floor surface 19.

[0090] In this sheath structure, the sheath body 13 forms a truss structure with the sheath fixing parts 17 embedded in the filler 23, and is firmly fixed to the bottom surface 33 of the groove 21. The sheath fixing parts 17 have a simple structure consisting of a base 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 33 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.

[0091] Furthermore, in this structure of the sheath, the wings 39 are attached to the sheath body 13 at an angle of 45° relative to the longitudinal direction of the sheath body 13 in a plan view. This allows the wings 39 to have a greater extension length than when they are attached perpendicular to the longitudinal direction of the sheath body 13. This allows the wings 39 to make contact with the ground in shallow grooves 21 as well as deep grooves 21, compared to when they are attached perpendicular to the sheath body 13.

[0092] Furthermore, by inclining the wing portions 39, when the filler 23 is filled from the side of the shelving body 13, the flow resistance of the filler 23 is reduced compared to when the wing portions 39 are attached perpendicular to the longitudinal direction of the shelving body 13. In other words, the filler 23 is easier to fill, and the filling work can be carried out smoothly. As a result, the wing portions can be made long, allowing for a larger adjustment range to the bottom surface 33 and making it easier for the filler 23 to flow in.

[0093] Furthermore, in this sheath structure, the space between the wing main body 57 and the base 37 forms the folding guide portion 49. The folding guide portion 49 is a portion that facilitates folding between the base 37 and the wing main body 57, such as a single elongated hole (such as a slit), multiple holes (intermittent or continuous), a groove that is narrowed in the thickness direction, or perforations. The wing 39 is easily folded relative to the base 37, which is fixed to the underside 15 of the sheath body 13, with the wing main body 57 tilting downward at the folding guide portion 49. As a result, the wing 39 can be easily bent at an accurate position.

[0094] In addition, in this chain structure, bending guide portions 45 are formed from both widthwise edges of wing portion 39. Bend guide portions 45 are recesses 53 formed by cutting out both widthwise edges of wing portion 39. As described above, bending guide portions 45 are formed on both sides of wing portion 39 that sandwich fixing hole 43. Wing portion 39 is inclined downward relative to base portion 37 and is deformed until tip portion 41 contacts bottom surface 33 of groove 21. In this state in which tip portion 41 contacts bottom surface 33, tip portion 41 and wing portion main body 57 are still flat.

[0095] In this state, when fastening member 51 inserted through fixing hole 43 is screwed into bottom surface 33 of groove 21, wing 39 is clamped to bottom surface 33, and tip 41 is bent at the boundary with wing main body 57. At this time, bend guide portion 45 of tip 41 becomes a weak portion, and tip 41 is bent (flexed) at the position of bend guide portion 45. This prevents tip 41 and wing main body 57 from deforming in unexpected positions.

[0096] Wing 39 bends at recesses 53 formed by cutting out both widthwise edges, forming corners at the ends of wing body 57. This makes it easier for inclined wing body 57 to absorb the unevenness of bottom surface 33, which is an uneven surface, compared to when the ends are linear, i.e., when they simply bend to form ridges, and allows for stable contact without slipping. As a result, tip 41 of wing 39 can be easily bent, and the edges of wing 39 at this bent portion become corners due to recesses 53, making it easier for them to bite into bottom surface 33.

[0097] In addition, in this splice structure, a recess 53 is cut from the tip side. The recess 53 has a notch central axis 55 inclined at a predetermined angle θ with respect to the extension direction a of the wing portions 39. As described above, the wing portions 39 extend at an angle of 45° with respect to the longitudinal direction of the splice body 13 in a plan view. The recess 53 is, for example, a U-shaped notch formed by cutting an oval along its minor axis. In this case, the notch central axis 55 of the recess 53 is the direction of the major axis of the oval.

[0098] When the tip 41 of this U-shaped recess 53 is bent parallel to the bottom surface 33 by screwing in the fastening member 51, the front half of the U-shaped recess 53, which is defined by the central axis 55 of the U-shaped cutout, becomes parallel to the bottom surface 33 together with the tip 41. On the other hand, the rear half of the U-shaped recess 53 remains as pointed ends 59 on both sides of the wing body 57, which slopes downward from the underside 15 of the hook body 13.

[0099] When the tip 41 of the wing body 57 is tightened to the bottom surface 33 by screwing in the fastening member 51, the wing body 57 is pulled toward the bottom surface 33, and this pointed end 59 bites into the bottom surface 33. This allows the end of the wing body 57 to firmly land on the bottom surface 33 without being affected by the unevenness of the bottom surface 33, which tends to be uneven. As a result, the end of the wing body 57 at this bent portion becomes the pointed end 59 due to the recess 53, so the wing body 39 can more easily follow the bottom surface 33 and bite into the bottom surface 33.

[0100] In the method for installing a slip-on 25 according to this embodiment, a slip-on fastener 17 is used for installation. The slip-on fastener 17 has a base 37 fixed to the underside 15 of the slip-on main body 13, with wings 39 extending parallel to the underside 15. The slip-on main body 13 is fixed to a frame. That is, the slip-on main body 13 is fixed by connecting the lower ends of the vertical frames 35 of the frame. In an opening in the building frame, for example, where the frame is to be installed, a groove 21 is formed in advance by cutting the floor 19 so that the slip-on main body 13 can be placed. In the installation process, the frame is installed, and the slip-on main body 13 is placed in the groove 21 and positioned at a predetermined position in the groove 21.

[0101] After the positioning of the strap body 13 is completed, the tip 41 of the strap fixing part 17 protruding from the side edge of the strap body 13 is pressed downward in the bending process, and the wing part 39 is deformed downward. The tip 41 of the wing part 39 deformed downward is brought into contact with the bottom surface 33.

[0102] In the fixing process, fastening members 51 are inserted into fixing holes 43 provided behind the tip portions 41 of the wing portions 39, which are bent with the tip portions 41 in contact with the bottom surface 33. When the fastening members 51 are screwed into the bottom surface 33, the tip portions 41 of the wing portions 39 are bent at the positions of the bend guides 45 formed on both sides of the fixing holes 43 and fixed so that they are approximately parallel to the bottom surface 33. In other words, the tip portions 41 are deformed along a straight line connecting the two bend guides 45 formed on both sides of the wing portions 39. The ends of the wing portions 39, which are rearward of the tip portions 41, are drawn toward the tip portions 41 that are fastened to the bottom surface 33. As a result, the wing portions 57 are pressed into the bottom surface 33, firmly contacting the bottom surface 33 and becoming immobile.

[0103] As a result, the strap body 13, which has been positioned, is completely fixed to the bottom surface 33 of the groove 21 via the strap fixing portion 17.

[0104] In the filler filling process, filler 23 such as mortar is filled into the grooves 21 of the hook body 13, forming a filler-finished surface that is flush with the floor surface 19. The filler 23 embeds at least a portion of the side surface of the hook body 13, excluding the top surface 11, and the hook fixing part 17. At this time, the hook body 13 is prevented from lifting up from the bottom surface 33 by the hook fixing part 17, which is fixed to the bottom surface 33.

[0105] In this method of installing the sheath 25, the sheath body 13 is firmly fixed to the bottom surface 33 of the groove 21 by forming a truss structure with the sheath fixing parts 17 embedded in the filler 23. The sheath fixing parts 17, which are fixed to the sheath body 13, are fixed to the bottom surface 33 with fastening members 51. Therefore, in the installation method of the sheath 25, 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 33 of the groove 21 with a simple structure and without increasing the number of parts.

[0106] In the fastening member 47 for a string according to this embodiment, wings 39 having a tip 41 are formed on a base 37 fixed to the underside 15 of the string body 13. In other words, the fastening member 47 for a string has a simple structure consisting of the base 37, wings 39, and tip 41, and is formed as a single component that is attached and fixed to the string body 13.

[0107] The base 37 of the strap fixing member 47 is fixed to the lower surface 15 of the strap body 13 by, for example, welding, and is integrated with the strap body 13 .

[0108] After the positioning of the strap body 13 is completed, the tip 41 of the strap fixing member 47 protruding from the side edge of the strap body 13 is pressed downward, and the wing 39 is deformed downward. The tip 41 of the wing 39 deformed downward is in contact with the bottom surface 33.

[0109] Wing 39 is bent with tip 41 in contact with bottom surface 33, and fastening member 51 is inserted into fixing hole 43 provided behind tip 41. When fastening member 51 is screwed into bottom surface 33, tip 41 of wing 39 is bent at bending guide portions 45 formed on both sides of fixing hole 43 and fixed approximately parallel to bottom surface 33. The end of wing main body 57 of wing 39, which is rearward of tip 41, is drawn toward tip 41 which is fastened to bottom surface 33. As a result, wing main body 57 bites into bottom surface 33, firmly contacts bottom surface 33, and becomes immobile.

[0110] As a result, the positioning of the strap body 13 is completed, and the strap body 13 is fixed to the bottom surface 33 of the groove 21 by the strap fixing member 47 without any fire.

[0111] The fixing member 47 for the hook is embedded in the filler 23 which is flush with the floor surface 19 by filling the groove 21 with the filler 23, together with at least a portion of the side surface of the hook body 13 excluding the top surface 11.

[0112] The strap fixing member 47 has a truss structure that supports the strap body 13 between itself and the bottom surface 33 of the groove 21, firmly fixing it in place. Therefore, the strap fixing member 47 does not require welding, has a simple structure, and can fix the strap body 13 to the bottom surface 33 of the groove 21 without increasing the number of parts.

[0113] In the string fixing member 47 according to this embodiment, the fold guide portion 49 is between the wing main body 57 and the base 37. The fold guide portion 49 is a portion that facilitates bending of the base 37 and the wing main body 57, such as a single elongated hole (such as a slit), multiple holes (intermittent or continuous), a groove that narrows in the thickness direction, or perforations. The wing 39 is easily bent with the wing main body 57 tilting downward at the fold guide portion 49 relative to the base 37 fixed to the underside 15 of the string main body 13. The string fixing member 47 having the fold guide portion 49 makes it easy to bend the wing 39 at the correct position.

[0114] In addition, in this hanging fixing member 47, bending guide portions 45 are formed from both edges of the wing portions 39 in the width direction.

[0115] The bending guide portions 45 are recesses 53 formed by cutting out both edges of the wing portions 39 in the width direction. As described above, the bending guide portions 45 are formed on both sides of the wing portions 39 that sandwich the fixing hole 43. The wing portions 39 are inclined downward relative to the base portions 37 and are deformed until the tip portions 41 contact the bottom surfaces 33 of the grooves 21. When the tip portions 41 contact the bottom surfaces 33, the tip portions 41 and the wing portions main bodies 57 are still flat.

[0116] In this state, when fastening member 51 inserted through fixing hole 43 is screwed into bottom surface 33 of groove 21, fixing hole 43 is tightened against bottom surface 33, and tip portion 41 bends at the boundary with wing main body 57. At this time, bend guide portion 45 of tip portion 41 becomes a weak portion, and tip portion 41 is bent (flexed) at the position of bend guide portion 45. This prevents tip portion 41 and wing main body 57 from deforming in unexpected positions.

[0117] Wing 39 bends at recesses 53 formed by cutting out both widthwise edges, forming corners at the ends of wing body 57. This makes it easier for inclined wing body 57 to absorb the unevenness of bottom surface 33, which is an uneven surface, compared to when the ends are linear, allowing for stable contact without slipping. As a result, tip 41 of wing 39 can be easily bent, and the edges of wing 39 at this bent portion become corners due to recesses 53, making it easier for them to bite into bottom surface 33.

[0118] Furthermore, in this threading fixture 47, a recess 53 is cut from the tip side. The recess 53 has a notch central axis 55 inclined at a predetermined angle θ with respect to the extension direction a of the wing portions 39. As described above, the wing portions 39 extend at an angle of 45° with respect to the longitudinal direction of the threading body 13 in a plan view. The recess 53 is, for example, a U-shaped notch formed by cutting an oval along its minor axis. In this case, the notch central axis 55 of the recess 53 is the direction of the major axis of the oval.

[0119] When the tip 41 of this U-shaped recess 53 is bent parallel to the bottom surface 33 by screwing in the fastening member 51, the front half of the U-shaped recess 53, which is defined by the central axis 55 of the U-shaped cutout, becomes parallel to the bottom surface 33 together with the tip 41. On the other hand, the rear half of the U-shaped recess 53 remains as pointed ends 59 on both sides of the wing body 57, which slopes downward from the underside 15 of the hook body 13.

[0120] When the fastening member 51 is screwed into the bottom surface 33, the tip 41 of the wing body 57 is pulled toward the bottom surface 33, and this pointed end 59 bites into the bottom surface 33. This allows the end of the wing body 57 to land firmly on the bottom surface 33 without being affected by the unevenness of the bottom surface 33, which tends to be uneven. As a result, the end of the wing 39 at this bent portion becomes the pointed end 59 due to the recess 53, so the wing 39 can more easily follow the bottom surface 33 and bite into the bottom surface 33.

[0121] [Second embodiment] Next, a second embodiment will be described.

[0122] 13 is a plan view of a strap fixing part 65 used in a strap structure according to the second embodiment. In this second embodiment, the same members and parts as those shown in the first embodiment are designated by the same reference numerals, and redundant explanations will be omitted. In the structure of the strap according to the second embodiment, a guide 67 for positioning the wing portion 39 relative to the strap body 13 is provided on the strap fixing portion 65 .

[0123] The guides 67 may be, for example, guide recesses formed by cutting out both edges of the strap fixing part 65. The guide recesses are located on an extension of the notch central axis 55 in the bending guide part 45 formed in the strap fixing part 65. As in the first embodiment, the strap fixing part 65 is fixed to the underside 15 of the strap main body 13 at an angle of 45° with respect to the longitudinal direction of the strap main body 13.

[0124] The rear end of the base 37 of the hanging fixture 65 is pointed, forming the apex of a triangle. The angle between the two sides of this triangle that sandwich the apex is 90°.

[0125] The second embodiment of the fasteners 65 may be fixed in pairs to the underside 15 of the fastener body 13 and used integrally with the fastener body 13, or may be handled as a separate component from the fastener body 13. In this case, the fasteners 65 separate from the fastener body 13 can be referred to as a fastener member 69. The fastener member 69 can be attached to the underside 15 of various shapes of fastener bodies 13 by attachment means such as welding, screwing, or fastening.

[0126] FIG. 14 is a bottom view of the chain body 13 to which the chain fixing member 69 shown in FIG. 13 is attached. In this chain structure, the chain fixing portion 65 has a guide 67 for positioning the wing portion 39 relative to the chain body 13. The chain fixing portion 65 is fixed to the chain body 13 by welding, for example, at a welded portion 71 in a factory before delivery to the construction site, rather than at the construction site. The guide 67 can be a guide recess formed on both edges of the wing portion 39. This notch is inclined at an angle of 45° with respect to the center line 75 (see FIG. 13) of the wing portion 39, where the imaginary line 73 (see FIG. 13) connecting the bend guide portion 45 formed on the opposite side edge of the chain fixing portion 65 is welded.

[0127] Therefore, when fixing the wing 39 to the underside 15 of the slider body 13, the wing 39 can be easily positioned at a 45° angle relative to the longitudinal direction of the slider body 13 in a plan view by aligning the bending guide 45 and the guide 67 with the edge of the slider body 13. As a result, the orientation and angle of the slider fixing part 65 relative to the slider body 13 can be easily determined, facilitating the installation work on the slider body 13.

[0128] Furthermore, similar to the structure of the strap, when the strap fixing member 69 as a single component is fixed to the underside 15 of the strap body 13, it can be easily positioned at a 45° angle relative to the longitudinal direction of the strap body 13 in a plan view by aligning the bending guide portion 45 and the guide 67 with the edge of the strap body 13. As a result, the direction and angle of the strap fixing member 65 relative to the strap body 13 can be easily determined, facilitating the installation work on the strap body 13.

[0129] Next, a modified example of the structure of the hook according to the second embodiment will be described.

[0130] FIG. 15 is a plan view of a modified example of a fastening member 69 for hanging in which the guide 67 is printed or the like. The guide 67 may be a printed or engraved marking such as a line or marking on the plate surface of the hanging fixture 65. The printed or engraved guide 67 can prevent the strength of the hanging fixture 65 from decreasing.

[0131] FIG. 16(a) is a plan view of a modified fastening member 69 for hanging shoes in which the guide 67 is an embossed portion, and (b) is a side view of (a). The guide 67 may also be a bulge 77 formed by embossing or sheet metal processing. The sheet metal processing may be, for example, molding using a turret punch press or processing that simultaneously performs die-cutting and embossing. Guide 67 with a bulge 77 can prevent a decrease in strength of the hanging fixing part 65 compared to a notch. Furthermore, positioning can be performed without slippage during alignment.

[0132] FIG. 17 is a plan view of a modified example of a fastening member 69 for hanging in which the guide 67 has a step portion 79. In FIG. The guide 67 may also be a step 79 provided on the outer shape of the hanging fixing part 65. The guide 67 with the step 79 can prevent a decrease in strength of the hanging fixing part 65 compared to a notch. Also, the shape can be made simple by die-cutting.

[0133] Therefore, according to the structure of the slip-on according to this embodiment, the slip-on 25 can be easily installed in the trench 21 without firearms.

[0134] According to the construction method of the knot 25 of this embodiment, fireless construction can be achieved without using any welding equipment, and complicated work processes such as preparing, transporting, and removing the welding equipment are not required, which simplifies construction and reduces construction time.

[0135] According to the threading fixing members 47 and 69 of this embodiment, the threading body 13 can be fixed to the bottom surface 33 of the groove 21 by fireless construction without using any welding equipment, eliminating the need for complicated work processes such as preparing, transporting, and removing the welding equipment, simplifying construction and reducing construction time.
