Description

[Technical Field]

[0001] The present invention relates to a structure of a kutsuzuri and a method of constructing a kutsuzuri. [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 above-mentioned door frame structure requires a separate frame from the door frame itself, and the door frame is fixed based on the fixed state of the frame, which differs from the assembly method based on the building frame itself. Because the door frame forms the lower end of the door frame and is fixed at the same level as the floor, it is preferable to install the door frame after the floor is ground, and then fill the gap between the door frame and the groove formed by the ground. The door frame itself, which connects the lower ends of the steel door frame (three-sided jamb) with each other, has a U-shaped opening on the bottom, as mentioned above, making it difficult to fill with mortar. In other words, the U-shaped design can cause the mortar to flow around the inside of the door frame, potentially resulting in insufficient mortar filling inside the door frame. For this reason, with this type of steel door frame, the door fitting contractor must first turn the door frame upside down to allow the mortar to easily flow inside the door sill, then the plastering contractor will fill it with mortar, and once the mortar has hardened, the door fitting contractor will turn the door sill downwards again to secure the door frame, and then fill in any gaps between the door sill and the floor with mortar, which is a complicated process involving multiple trades.As a result, there was the problem of long construction times.

[0005] The present invention has been made in consideration of the above situation, and its purpose is to provide a kutsuzuri structure and construction method that can shorten the construction period by eliminating the need for the cumbersome work of filling the kutsuzuri with filler such as mortar, which is done by simply turning the kutsuzuri upside down. [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 slider according to claim 1 of the present invention comprises a slider body 17 having a long, strip-shaped upper surface 15, a groove 13 formed by cutting through a floor surface 11 with a width greater than the width of the slider body 17, and the slider body 17 is disposed inside the groove 13, and a filler 19 filled into the groove 13 with the upper surface 15 of the slider body 17 exposed, A fixing member 23 is provided upright on the bottom surface 21 of the groove 13, The threading body 17 is formed in a flat plate shape, and has an anchor frame portion 25 of a predetermined shape fixed to its underside 27, and this anchor frame portion 25 is fixed to the fixing member 23, and the upper surface 15 is positioned flush with or elevated above the floor surface 11, and at least a portion of the side surface in the plate thickness direction, excluding the upper surface 15, and the anchor frame portion 25 are embedded in the filler 19 that is flush with the floor surface 11 and filled in the groove 13.

[0007] In this structure of the slide, a slide body 17 is placed in a groove 13 formed by cutting into a floor surface 11. The groove 13 is formed with a width wider than the slide body 17, and the slide body 17 is placed inside. The slide body 17 has an elongated strip-shaped upper surface 15 that extends along the groove 13. A filler 19 is filled into the groove 13 in which the slide body 17 is placed. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the filler 19 is filled. In this structure of the shelving unit, the shelving unit body 17 is formed in the shape of a long flat plate extending in the direction along the groove 13 . The width of the sheath body 17 in the direction perpendicular to the longitudinal direction is narrower than the groove width, so that in the groove 13 in which the sheath body 17 is arranged, a filler filling opening 35 is formed between the groove opening and the sheath body 17. The filler 19 is poured from this filler filling opening 35 below the sheath body 17. The strap body 17 has an anchor frame 25 of a predetermined shape, for example, a U-shape that opens upward, fixed to the underside 27. This anchor frame 25 is fixed by welding or the like to a fixing member 23 that is erected on the bottom surface 21. Therefore, in this state, the strap body 17 is positioned relative to the groove 13 and floor surface 11. The positioned strap body 17 is placed so that the top surface 15 is flush with or higher than the floor surface 11, for example, by about 3 mm. The filler 19 that is filled into the groove 13 from the filler filling opening 35 is filled in contact with the underside 27 of the sheath body 17. In other words, no gap is created between the underside 27 of the sheath body 17 and the filler 19. The filler 19 is filled into the groove 13 flush with the floor surface 11, thereby embedding at least a portion of the side surface in the thickness direction of the sheath body 17 excluding the top surface 15, and the anchor frame portion 25. With this structure, the sheath body 17 is flat, which makes it easy to pour the filler 19 onto the underside of the sheath body 17. The filler 19 flows into the underside 27 of the sheath body 17, and the anchor frame 25 fixed to the fixing member 23 is embedded in the filler 19, so the sheath body 17 is firmly fixed to the frame with high strength. This allows the filler 19 to be filled into the underside 27 of the sheath body 17 without any gaps, and the underside 27 of the sheath body 17 and the filler 19 to be firmly fixed together. Furthermore, it eliminates the need for the cumbersome filling work of turning the kutsuzuri upside down and only filling the kutsuzuri, as was done with conventional structures. This means that plastering work and fitting work are not intertwined, making construction work smoother and shortening the construction period. Furthermore, the anchor frame portion 25 is not elongated in the same direction as the longitudinal direction of the string body 17, but is formed into a predetermined shape such as a U-shape using a narrow plate material, etc., so that the flow of the filler 19 is not easily obstructed and gaps are less likely to occur between the underside 27 of the string body 17 and the filler 19, while ensuring the fixing strength of the string body 17.

[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 threading body 17 is characterized in that it has a rounded portion 29 where the corner where the side surface in the thickness direction and the upper surface 15 intersect is chamfered.

[0009] In this structure, a flat slide body 17 is placed in a groove 13 formed by cutting into the floor surface 11. The groove 13 is filled with filler 19, flush with the floor surface 11. The filler 19 is embedded in at least a portion of the side surface of the slide body 17 in the thickness direction, excluding the top surface 15. Therefore, if the top surface 15 of the slide body 17 is not flush with the finished surface 20 of the filler 19, the corner where the side surface of the slide body 17 in the thickness direction intersects with the top surface 15 will form a step that protrudes upward from the finished surface 20 of the filler 19. This step, which is about 3 mm, will collide with heavy fixtures and other items passing through it. This may cause the slide body 17 to curl up. In the structure of the shoe slide, these corners are chamfered to form R-sections 29, which can reduce the external force acting on the shoe slide body 17 when it comes into contact with something, and can prevent the shoe slide body 17 from rolling up. It also makes it less likely for pedestrians to trip when passing through.

[0010] The structure of a string of the present invention according to claim 3 comprises a string of the main body 37 having a long strip-shaped upper surface 15, a groove 13 formed by cutting the floor surface 11 with a width wider than the width of the string of the main body 37 and in which the string of the main body 37 is placed, and a filler 19 filled in the groove 13 with the upper surface 15 of the string of the main body 37 exposed, A fixing member 23 is provided upright on the bottom surface 21 of the groove 13, The threading body 37 is characterized in that it has a pair of side plate portions 41 that hang down into the groove from each of a pair of long sides of the top surface 15, at least one of which has a filler introduction portion 39 that allows the filler 19 to pass through, an upwardly opening U-shaped anchor frame portion 25 that is fixed to the bottom surface 27 and this anchor frame portion 25 is fixed to the fixing member 23, the top surface 15 is positioned flush with the floor surface 11 or is higher than the floor surface 11, and at least a portion of the side of the side plate portions 41 excluding the top surface 15 and the anchor frame portion 25 are embedded in the filler 19 that is filled in the groove 13 flush with the floor surface 11.

[0011] In this structure of the slide, a slide body 37 is placed in a groove 13 formed by cutting into the floor surface 11. The groove 13 is formed with a width wider than the slide body 37, and the slide body 37 is placed inside. The slide body 37 has an elongated, strip-shaped upper surface 15 that extends along the groove 13. A filler 19 is filled into the groove 13 in which the slide body 37 is placed. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the filler 19 is filled. In this shelving structure, shelving body 37 has a pair of side plate portions 41 that hang down into groove 13 from each of a pair of long sides of upper surface 15. At least one of the pair of side plate portions 41 has a filler introduction portion 39 that allows filler 19 to pass through. The width of the sheath body 37 in the direction perpendicular to the longitudinal direction is narrower than the groove width, so that in the groove 13 in which the sheath body 37 is disposed, a filler filling opening 35 is formed between the groove opening and the sheath body 37. The filler 19 is poured from this filler filling opening 35 downward into the sheath body 37. The chamfer body 37 has an upwardly opening U-shaped anchor frame 25 fixed to the underside 27. This anchor frame 25 is fixed by welding or the like to a fixing member 23 erected on the bottom surface 21. Therefore, in this state, the chamfer body 37 is positioned relative to the groove 13 and floor surface 11. The positioned chamfer body 37 is placed so that the top surface 15 is flush with or higher than the floor surface 11, for example, by about 3 mm. The filler 19 that is filled into the groove 13 from the filler filling opening 35 passes through the filler introduction section 39 and is filled in contact with the underside 27 of the sheath body 37. In other words, no gap is created between the underside 27 of the sheath body 37 and the filler 19. The filler 19 is filled into the groove 13 flush with the floor surface 11, thereby embedding at least a portion of the side surface in the thickness direction of the sheath body 37 excluding the top surface 15, and the anchor frame section 25. In this structure of the sheath, the sheath body 37 has a pair of side plates 41, and at least one of the side plates 41 has a filler introduction section 39, making it easy to pour the filler 19 into the underside of the sheath body 37 through the filler introduction section 39. The filler 19 flows into the underside 27 of the sheath body 37, and the anchor frame section 25 fixed to the fixing member 23 is embedded in the filler 19, so the sheath body 37 is firmly fixed to the frame with high strength. This allows the filler 19 to be filled into the underside 27 of the sheath body 37 without any gaps, firmly bonding the underside 27 of the sheath body 37 and the filler 19 together. Furthermore, it eliminates the need for the cumbersome filling work of turning the kutsuzuri upside down and only filling the kutsuzuri, as was done with conventional structures. This means that plastering work and fitting work are not intertwined, making construction work smoother and shortening the construction period. Furthermore, the anchor frame portion 25 is not elongated in the same direction as the longitudinal direction of the drag body 37, but is formed in a U-shape using a narrow plate material, etc., which makes it difficult to impede the flow of the filler 19 and makes it difficult for a gap to occur between the underside 27 of the drag body 37 and the filler 19, while ensuring the fixing strength of the drag body 37. In addition, the slider body 37 has a pair of side plates 41 that hang down into the groove from each of a pair of long sides of the top surface 15, and the side plates 41 are embedded in the filler 19, making the slider body 37 less likely to roll up compared to a flat slider body 37. The pair of side plates also increase the strength and rigidity of the slider body 37, making it less likely to dent.

[0012] The structure of the splice according to claim 4 of the present invention is the structure of the splice according to claim 3, One of the pair of side plate portions 41 hangs down shorter than the other, and a filling member 43 is provided between the pair of side plate portions 41 to fill the gap between the lower surface 27 and the filler 19.

[0013] In this sheath structure, the two long and short side plates 41 maintain the strength and rigidity of the sheath body 37. Furthermore, because the hanging length of the other side plate 41 is shortened, the gap between this side plate 41 and the bottom surface 21 of the groove 13 is increased, making it easier for the filler 19 to flow in. Furthermore, by fixing the stuffing member 43 to the underside 27 of the sheath body 37, the strength of the upper plate portion of the sheath body 37 is ensured, making the upper surface 15 less likely to be dented. Furthermore, by providing the stuffing member 43 on the underside 27, the underside 27 of the sheath body 37 is substantially lower than the finished surface 20 of the filler 19. This means that the filler 19 does not wrap around when it flows in, making it less likely for voids to form when the filler flows in.

[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 slipper body 17, 37 is characterized in that a plurality of embedding portions 45 that hang down from the lower surface 27 and are embedded in the filler 19 are provided at intervals in the longitudinal direction of the lower surface 27.

[0015] In this sheath structure, multiple embedded portions 45 hang down from the underside 27 of the sheath body 17, 37. The embedded portions 45 are spaced apart in the longitudinal direction of the underside 27 of the sheath body 17, 37. As a result, the embedded portions 45, which are integral with the underside 27, are embedded in the filler 19, improving the integration of the sheath body 17, 37 with the filler 19 and increasing the resistance (strength) of the sheath body 37 in the horizontal movement direction and the pull-out direction, making the sheath body 37 less likely to roll up.

[0016] The structure of a string of the present invention according to claim 6 comprises a string of the present invention body 55 having a long strip-shaped upper surface 15, a groove 13 formed by cutting the floor surface 11 with a width wider than the width of the string of the string body 55 and in which the string body 55 is placed, and a filler 19 filled in the groove 13 with the upper surface 15 of the string body 55 exposed, A fixing member 23 is provided upright on the bottom surface 21 of the groove 13, The slipper body 55 has a pair of side plate portions 41 hanging down from each of a pair of long sides of the top surface 15, and a fixing protrusion 59 that protrudes downward is provided between the pair of side plate portions 41 and is fixed to the fixing member 23, and a filling member 43 is provided between the pair of side plate portions 41 and the fixing protrusion 59, and the top surface 15 is positioned flush with the floor surface 11 or elevated above it, and at least a portion of the side of the side plate portion 41 excluding the top surface 15 and the fixing protrusion 59 are embedded in the filler 19 that is filled in the groove 13 flush with the floor surface 11.

[0017] In this structure of the slide, a slide body 55 is placed in a groove 13 formed by cutting into the floor surface 11. The groove 13 is formed with a width wider than the slide body 55, and the slide body 55 is placed inside. The slide body 55 has an upper surface 15 that is long and strip-shaped and runs along the groove 13. A filler 19 is filled into the groove 13 in which the slide body 55 is placed. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the filler 19 is filled. In this structure of the shelving unit, shelving unit body 55 has a pair of side plates 41 that hang down into groove 13 from each of a pair of long sides of upper surface 15. Since side plates 41 are formed with a short hanging length, the lower portions of side plates 41 become filler introduction portions 39, allowing filler 19 to pass through smoothly. The width of the sheath body 55 in the direction perpendicular to the longitudinal direction is narrower than the groove width, so that in the groove 13 in which the sheath body 55 is arranged, a filler filling opening 35 is formed between the groove opening and the sheath body 55. The filler 19 is poured from this filler filling opening 35 downward into the sheath body 55. The slider body 55 is provided with a fixing projection 59 between the pair of side plates 41, which protrudes downward and is fixed to the fixing member 23. A stuffing member 43 is provided between the pair of side plates 41 and the fixing projection 59. The slider body 55 is fixed by welding or the like to the fixing member 23 erected on the bottom surface 21 at the fixing projection 59. Therefore, in this state, the slider body 55 is positioned relative to the groove 13 and floor surface 11. The positioned slider body 55 is arranged so that the top surface 15 is flush with or higher than the floor surface 11, for example, by about 3 mm. The filler 19 filled into the groove 13 from the filler filling opening 35 passes under the side plate portion 41 and is filled in contact with the filling member 43 provided on the underside 27 of the sheath body 55. In other words, no gap is created between the underside 27 of the sheath body 55 and the filler 19. The filler 19 is filled into the groove 13 flush with the floor surface 11, thereby embedding at least a portion of the side surface in the plate thickness direction excluding the top surface 15 of the sheath body 55 and the fixing protrusions 59. In this structure of the sheath, the sheath body 55 has a pair of side plates 41 that hang down into the groove, making it easy to pour the filler 19 onto the underside of the sheath body 55. The filler 19 flows into the underside 27 of the sheath body 55, and the fixing protrusions 59 fixed to the fixing members 23 are embedded in the filler 19, so the sheath body 55 is firmly fixed to the frame with high strength. This allows the filler 19 to be filled into the underside 27 of the sheath body 55 without any gaps, and the underside 27 of the sheath body 55 and the filler 19 to be firmly fixed together. Furthermore, it eliminates the need for the cumbersome filling work of turning the kutsuzuri upside down and only filling the kutsuzuri, as was done with conventional structures. This means that plastering work and fitting work are not intertwined, making construction work smoother and shortening the construction period. Furthermore, the fixing protrusion 59 and the stuffing member 43 do not form a downward recess (dent) on the underside of the sheath body 55, so the flow of the filler 19 is less likely to be hindered, and gaps are less likely to occur between the underside 27 of the sheath body 55 and the filler 19, while ensuring the fixing strength of the sheath body 55.

[0018] The method for constructing a floor according to claim 7 of the present invention includes a chipping step of chipping a floor surface 11 to form a groove 13, a fixing portion installation step of providing fixing members 23 on the bottom surface 21 of the groove 13 at predetermined intervals in the extending direction of the groove 13; a fitting process in which a hook body 17 formed by connecting the lower ends of a pair of parallel, spaced apart vertical frames 33 of a three-sided frame 31, which are connected by an upper frame, is placed in the groove 13; a fixing step of fixing an anchor frame portion 25 provided on a lower surface 27 of the strap body 17 to the fixing member 23; A pair of side plate portions 41 hang down from each of a pair of long sides along the longitudinal direction of the long, band-shaped upper surface 15 of the hanging body 17, one of which hangs down shorter than the other, and form a filler introduction portion 39 that becomes a space between the lower side of the other side plate portion 41 and the bottom surface 21 of the groove 13, and through the filler introduction portion 39 a filler filling step of filling the groove 13 with a filler 19 so that the filler 19 is flush with the floor surface 11, and embedding at least a portion of the side surface of the hook body 17 excluding the top surface 15 and the anchor frame portion 25 into the filler 19; The present invention is characterized by comprising:

[0019] In this construction method, the body of the kutsuzuri 37 The lower ends of a pair of vertical frames 33 of the three-sided frame 31 are connected to each other. For example, at an opening in the building frame where the three-sided frame 31 is attached, the floor surface 11 is cut off, and the sliding door body 37 Before the jamb 31 is placed, a fixing member 23 is set upright on the bottom surface 21 of the groove 13. That is, an anchor pile or the like is fixed and set up so as to stand upright from the bottom surface 21. The clockwork body attached to the three-sided frame 31 37 A plurality of anchor frame portions 25 are provided on the lower surface 27 at predetermined intervals in the longitudinal direction. The three-sided frame 31 is the main body of the kutsuzuri. 37 The hook body is fixed to the frame so that it is in a predetermined position in the groove 13. 37 is fixed to a fixing member 23 erected on the bottom surface 21 by welding or the like. Three-sided frame 31, Kutsuzuri body 37 After the groove 13 is positioned and fixed in place, the groove 13 is filled with a filler 19. The filler 19 is filled to form a 37In other words, the anchor frame portion 25 provided on the lower surface 27 is embedded. 37 At least a part of the side surface of the floor 11 is embedded, and a finished surface 20 is finished to be flush with the floor surface 11. For this reason, the construction method for the Kutsuzuri eliminates the conventional work of turning the Kutsuzuri body upside down together with the three-sided frame 31 and filling the Kutsuzuri body with filler 19. After the three-sided frame 31 is delivered to the site and installed in the groove 13 through the erection process and fixing process, construction can be completed simply by plastering work, which involves filling the filler 19 in the filler filling process.

[0020] The method for constructing a floor according to claim 8 of the present invention includes a chipping step of chipping a floor surface 11 to form a groove 13, a fixing portion installation step of providing fixing members 23 on the bottom surface 21 of the groove 13 at predetermined intervals in the extending direction of the groove 13; a fitting process in which a hook body 37 formed by connecting the lower ends of a pair of parallel, spaced apart vertical frames 33 of a three-sided frame 31, in which the upper ends of the vertical frames 33 are connected by an upper frame, is placed in the groove 13; a fixing step of fixing an anchor frame portion 25 provided on the underside 27 of the strap body 37 to the fixing member 23; A pair of side plate portions 41 hang down from each of a pair of long sides along the longitudinal direction of the long, band-shaped upper surface 15 of the hanging body 37, one of which hangs down shorter than the other, and form a filler introduction portion 39 that becomes a space between the lower side of the other side plate portion 41 and the bottom surface 21 of the groove 13, and through the filler introduction portion 39 a filler filling step of filling the groove 13 with filler 19 so that the filler 19 is flush with the floor surface 11, and embedding at least a portion of the side surface of the hook body 37 excluding the upper surface 15, the anchor frame portion 25, and an embedding portion 45 hanging down from the lower surface 27 into the filler 19; The present invention is characterized by comprising:

[0021] This method of installing a shoelace involves the same steps as the above-mentioned method of installing a shoelace. That is, it includes a chipping step, a fixing portion installation step, a building step, a fixing step, and a filler filling step. In this method of installing a shoelace, in the filler filling step, the embedding portion 45, which is fixed and hangs down from the underside 27 of the shoelace body 37, is embedded in the filler 19 at the same time as the anchor frame portion 25. With this method of installing a shoelace, the embedding portion 45 is embedded in the filler 19 in addition to the anchor frame portion 25, resulting in a shoelace structure in which the shoelace body 37 is firmly fixed to the filler 19. [Effects of the Invention]

[0022] According to the structure of the kutsuzuri described in claim 1 of the present invention, the work of filling the filler, which is performed only on the kutsuzuri, is unnecessary; in other words, the complicated work of turning the kutsuzuri upside down and filling it with filler is unnecessary, and the filler is filled firmly on the underside of the kutsuzuri without creating any gaps, so that the fitting work and plastering work are not intertwined as in the past, construction work is smoother, and the construction period can be shortened.

[0023] According to the structure of the slipper described in claim 2 of the present invention, the corners of the slipper body are rounded, so that the upper surface protruding from the filler finishing surface passes through the rounded portion, and the step caused by this rounded portion is smooth, making it less likely to cause a tripping sensation.

[0024] According to the structure of the kutsuzuri described in claim 3 of the present invention, the filler filling work performed only on the kutsuzuri is unnecessary, i.e., the cumbersome work of turning the kutsuzuri upside down to fill the filler is unnecessary, and the filler passes through the filler introduction part and is filled in contact with the underside of the kutsuzuri, and is filled firmly on the underside without creating any voids, so that the construction work is smoother and the construction period can be shortened without intertwining the fitting work and plastering work as in the past.In addition, by providing side panels on the kutsuzuri body, the body of the kutsuzuri can be made less likely to turn up.

[0025] According to the structure of the sling described in claim 4 of the present invention, the hanging length of the other side plate is shortened, which increases the gap between this side plate and the bottom surface of the groove, thereby suppressing poor filling (filling) of the filler. In addition, the filling member increases the strength of the sling body, and the filling member does not form a downward recess (dent) on the underside of the sling body, making it less likely to obstruct the flow of the filler and less likely to create a gap between the underside of the sling body and the filler, thereby suppressing the occurrence of dent deformation of the sling body and ensuring the fixing strength of the sling body.

[0026] According to the structure of the strap of the fifth aspect of the present invention, the embedded portion fixed to the strap body is embedded in the filler, thereby making it possible to prevent the strap body from curling up.

[0027] According to the structure of the sling described in claim 6 of the present invention, the side plate portions hanging down from the long sides of the sling body are formed with a short hanging length, so a large filler filling space is opened between the sling body and the bottom surface of the groove, allowing the filler to flow in smoothly. Also, the fixing protrusions and the filling member do not form a downward recess (depression) on the underside of the sling body, so the flow of the filler is not easily obstructed and gaps are less likely to occur between the underside of the sling body and the filler, while ensuring the fixing strength of the sling body.

[0028] According to the construction method for Kutsuzuri described in claim 7 of the present invention, it is not necessary to turn upside down the frame on three sides to which the Kutsuzuri body is fixed, fill the Kutsuzuri only with filler, and then turn the frame upside down again and erect it after the filler has hardened, which was a conventional procedure. This eliminates the need for intertwining plastering work and fitting work, reduces complexity, and makes construction work smoother, thereby shortening the construction period.

[0029] According to the method for applying a shoelace as set forth in claim 8 of the present invention, it is possible to obtain a shoelace structure that is resistant to rolling up, in which the embedded portion is embedded in the filler. [Brief explanation of the drawings]

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a structure of a splice according to the first embodiment, and FIG. 2 is a cross-sectional view of the structure of the splice according to the first embodiment taken in a direction perpendicular to the extension direction of the grooves 13. As shown in FIG. The structure of the slide according to the first embodiment comprises a slide body 37 having a long, strip-shaped upper surface 15, a groove 13 cut into the floor surface 11 with a width wider than the width of the slide body 37 and inside which the slide body 37 is placed, and a filler 19 filled into the groove 13 with the upper surface 15 of the slide body 37 exposed. Note that the filler 19 may be mortar, concrete, or an adhesive anchor such as Chemical Anchor (registered trademark), but in the following embodiments, the filler 19 will be described as mortar 19.

[0032] A fixing member 23 is erected on the bottom surface 21 of the groove 13. The fixing member 23 is a member that can maintain strength and provide temporary fixation, such as a member made of steel or ceramic, and is, for example, an anchor pile or reinforcing bar, and is installed by being driven perpendicularly into the bottom surface 21 after the groove 13 is formed.

[0033] In this embodiment, the threading body 37 has a pair of side plate portions 41 hanging down from each of a pair of long sides along the longitudinal direction of the smooth top surface 15. At least one of these side plate portions 41 has a filler introduction portion 39 through which mortar 19 passes. In this embodiment, one of the pair of side plate portions 41 is shorter and hangs down than the other. This ensures the filler introduction portion 39 between the other side plate portion 41 and the bottom surface 21. The threading body 37 is preferably made of a material such as steel, stainless steel, or aluminum.

[0034] The anchor frame 25 is fixed to the underside 27 of the sheath body 37, for example, by welding. The anchor frame 25 is made of, for example, steel. Steel is a suitable steel material. In this embodiment, the anchor frame 25 is made of a narrow plate material, and is formed into a short, narrow U-shape that opens upward, with its width being sufficiently shorter than the longitudinal length of the sheath body 37. The mating upper ends of the anchor frame 25 are fixed to the underside 27 of the sheath body 37. A plurality of anchor frames 25 are fixed to the sheath body 37, spaced apart from each other in the longitudinal direction. The spacing between each anchor frame portion 25 is set according to the length of the hanging body 37. For example, if the length of the hanging body 37 is about 900 mm, they will be provided in three locations: one about 150 mm from each end of the hanging body 37, and one intermediate location, i.e., a location spaced about 300 mm apart.

[0035] This anchor frame portion 25 is fixed to the fixing member 23 erected on the bottom surface 21 of the groove 13. That is, the arrangement position of this fixing member 23 is also set to a spacing position of the above dimension. The anchor frame portion 25 and the fixing member 23 can be fixed together by, for example, welding or fastening using a threaded connection means (screws, bolts, etc.). Note that the anchor frame portion 25 and the fixing member 23 do not need to be in an exact dimensional position; by forming the anchor frame portion 25 to a predetermined width, any error can be absorbed.

[0036] As shown in Figure 2, with the anchor frame 25 fixed to the fixing member 23, the link body 37 is positioned so that its top surface 15 is flush with or elevated above the floor surface 11 and the finished mortar surface 20. In this embodiment, the top surface 15 of the link body 37 protrudes about 3 mm from the floor surface 11. In the link body structure, at least a portion of the side surface of the side panel 41, excluding the top surface 15, and the anchor frame 25 are embedded in the mortar 19 filled in the groove 13 so as to be flush with the floor surface 11. Therefore, the top surface 15 of the link body 37 protrudes about 3 mm from the finished surface 20 of the mortar 19 filled in the groove 13.

[0037] In the structure of the tsutsuri in this embodiment, one of a pair of side plate portions 41 is formed shorter than the other and hangs down, and a filler member 43 is provided between the pair of side plate portions 41 to fill the gap between the underside 27 and the mortar 19. The filler member 43 can be, for example, a steel plate. In the figure, two plates are stacked to achieve a predetermined thickness, but in reality, the filler member 43 is installed with a thickness equal to or slightly longer than the length of the short side plate portion 41 to match the hanging length of the short side plate portion 41.

[0038] Furthermore, in the structure of the slip link of this embodiment, a plurality of embedding portions 45 that hang down from the underside 27 and are embedded in the mortar 19 are provided on the slip link body 37 at intervals along the longitudinal direction of the underside 27. The embedding portions 45 can be bolts or screws that are welded or screwed to the filling member 43. By using bolts as the embedding portions 45, the threads are embedded in the mortar 19, thereby increasing the pull-out strength of the mortar 19.

[0039] The method for constructing a mortar according to the first embodiment includes a chipping step, a fixing portion installation step, a building step, a fixing step, and a mortar filling step.

[0040] In the chipping process, the floor surface 11 is chipped to form the groove 13. The groove 13 is formed with a width greater than the width of the board of the hook body 37. In this embodiment, as shown in Figure 2, the groove is formed with a width greater than the width of the vertical frame 33 of the three-sided jamb. The groove 13 accommodates the anchor frame part 25 and is formed with a depth such that the top surface 15 of the hook body 37 is flush with the floor surface 11 or protrudes by about 3 mm.

[0041] In the fixing part installation process, fixing members 23 are provided on the bottom surface 21 at predetermined intervals in the extension direction of the groove 13. The intervals between each individual member 23 are set according to the width of the jamb 31 to be incorporated into the frame, i.e., the length of the hanging body 37. For example, if the length of the hanging body 37 is about 900 mm, the fixing members 23 are provided at three locations on the bottom surface 21: one about 150 mm from each end of the hanging body 37, and another about 300 mm apart between these positions, i.e., at positions corresponding to the anchor frame parts 25. The fixing members 23 are anchor piles or the like, and are fixed by driving them into the bottom surface 21 of the groove 13 approximately perpendicularly.

[0042] The erection process is performed by erecting the jamb 31 into the groove 13. The jamb 31 is formed by connecting the upper ends of a pair of spaced-apart, parallel vertical frames 33 with an upper frame (not shown). The sliding frame body 37 is provided in a state in which the lower ends of the vertical frames 33 of the jamb 31 are connected with each other. In other words, the jamb 31 becomes a square frame (four-sided frame) with the sliding frame body 37 provided. In the erection process, the jamb 31 with the sliding frame body 37 attached is erected so that the sliding frame body 37 is positioned in a predetermined position in the groove 13. In other words, the jamb 31 and the sliding frame body 37 are fixed to the frame body at the predetermined positions.

[0043] In the fixing step, the anchor frame portion 25 provided on the lower surface 27 of the strap body 37 is fixed to the fixing member 23. The fixing means is welding. Note that a stuffing member 43 is fixed in advance to the lower surface 27 of the roller body 37. An embedding portion 45 is also fixed to the stuffing member 43. These can be fixed by welding, for example.

[0044] In the mortar filling process, mortar 19 is filled into the groove 13 in which the base 37 is placed so as to form a finished surface 20 that is flush with the floor surface 11. The mortar 19 fills at least a portion of the side of the base 37, excluding the top surface 15 of the base 37, the anchor frame portion 25, and the embedding portion 45. The mortar 19 filled into the groove 13 hardens while adhering to the filling member 43 provided on the underside 27 of the base 37. After curing for a predetermined time, the mortar 19 hardens, and the mortar 19 and base 37 become one body, completing the installation of the base.

[0045] Next, the operation of the first embodiment will be described.

[0046] In this structure, a slide body 37 is placed inside a groove 13 formed by cutting into the floor surface 11. The groove 13 is wider than the width of the slide body 37. The slide body 37 is made of steel, for example, and has a rectangular strip-shaped upper surface 15 that is narrower than the width of the groove 13 and extends along the groove 13. The groove 13 in which the slide body 37 is placed is filled with mortar 19. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the mortar 19 is filled.

[0047] In this structure of the slipper, slipper body 37 has a pair of side plates 41 that hang down into the groove from each of a pair of long sides along the longitudinal direction of top surface 15. Side plates 41 are bent at right angles from top surface 15, so the corners become rounded portions 29, making it less likely for people to trip. At least one of the pair of side plates 41 has a filler introduction portion 39 below, which allows mortar 19 to pass through.

[0048] The width of the board in the direction perpendicular to the longitudinal direction of the shim body 37 is narrower than the width of the groove, so in the groove 13 in which the shim body 37 is placed, a mortar filling opening 35 is formed between the groove opening and the shim body 37. Mortar 19 is poured from this mortar filling opening 35 below the shim body 37.

[0049] The chamfer body 37 has an upwardly opening U-shaped anchor frame 25 fixed to the underside 27. This anchor frame 25 is fixed by welding or the like to a fixing member 23 erected on the bottom surface 21. Therefore, in this state, the chamfer body 37 is positioned relative to the groove 13 and floor surface 11. The positioned chamfer body 37 is placed so that the top surface 15 is flush with or higher than the floor surface 11, for example, by about 3 mm.

[0050] The mortar 19 filled into the groove 13 from the mortar filling opening 35 passes through the filler introduction section 39 and is filled in contact with the underside 27 of the anchor body 37. In other words, the underside of the anchor body 37 does not have a downward depression (recess) that the mortar 19 would have to flow around when it flows in, so the mortar 19 is filled without creating any gaps between the underside 27 of the anchor body 37 and the mortar 19. The mortar 19 is flush with the floor surface 11, forming the finished surface 20, and by filling the groove 13, it embeds at least a portion of the side surface in the thickness direction of the anchor body 37 excluding the top surface 15, as well as the anchor frame section 25 and the embedding section 45.

[0051] In this structure, the mortar body 37 has a pair of side plates 41, and the lower part of at least one of the side plates 41 has a filler introduction section 39 that provides a space through which the mortar 19 can easily flow, making it easy to pour the mortar 19 into the underside of the mortar body 37 through the filler introduction section 39. The mortar 19 flows into the underside 27 of the mortar body 37, and the anchor frame section 25 fixed to the fixing member 23 is embedded in the mortar 19, so the mortar body 37 is firmly fixed to the framework with high strength. This allows the mortar 19 to be filled into the underside 27 of the mortar body 37 without any gaps, and the mortar 19 can be fixed to the underside 27 of the mortar body 37 without creating any voids.

[0052] In addition, it eliminates the need for the mortar filling work that is only performed on the kutsuzuri in conventional structures, i.e., the work of turning the kutsuzuri upside down and filling the mortar inside, which means that plastering work and fitting work are not intertwined, reducing complexity and making construction work smoother, thereby shortening the construction period.

[0053] Furthermore, the anchor frame portion 25 is not a long, elongated shape that follows the longitudinal direction of the anchor body 37, but is configured to be arranged at predetermined locations spaced apart, so that it does not interfere with the flow of the mortar 19, and is embedded in the mortar 19 while making it difficult for gaps to occur between the underside 27 of the anchor body 37 and the mortar 19, thereby ensuring the fixing strength of the anchor body 37.

[0054] In addition, the threading body 37 is provided with a pair of side plates 41 that hang down into the groove 13 from each of a pair of long sides along the longitudinal direction of the top surface 15, and these side plates 41 are embedded in the mortar 19, making the threading body 37 less likely to roll up. Also, the pair of side plates can increase the strength and rigidity of the threading body 37, making it less likely to deform.

[0055] Furthermore, with this structure of the shim, the strength and rigidity of the shim body 37 can be maintained by the two long and short side plate portions 41. The hanging length of the other side plate portion 41 is shortened, which increases the gap between this side plate portion 41 and the bottom surface 21 of the groove 13, making it easier for the mortar 19 to flow in. Furthermore, by providing the packing member 43 on the underside 27 of the shim body 37, the strength of the shim body 37 is ensured, deformation such as twisting and bending of the shim body 37 is suppressed, and the upper surface 15 is less likely to be dented.

[0056] Furthermore, by providing the packing members 43 on the underside 27, the underside 27 of the mortar body 37 is substantially lower than the finished surface 20 of the mortar 19, making it less likely that voids will occur when the mortar flows in. In other words, the underside of the mortar body 37 does not have any downward depressions (recesses) that the mortar 19 would have to go around when flowing in, which prevents poor flow (filling) of the mortar 19, such as the formation of voids on the underside 27 of the mortar body 37. Furthermore, the packing members 43 increase the strength of the mortar body 37 and make it less likely that voids will occur between the mortar body 37 and the mortar 19, thereby preventing the mortar body 37 from being deformed by dents or the like.

[0057] In this structure of the link, multiple embedded portions 45 hang down from the underside 27 of the link body 37. The embedded portions 45 are spaced apart in the longitudinal direction of the underside 27 of the link body 37. As a result, the embedded portions 45, which are integral with the underside 27, are embedded in the mortar 19, increasing the resistance (strength) of the link body 37 in the horizontal movement direction and the pull-out direction, making the link body 37 even more difficult to turn over.

[0058] Furthermore, in the method for constructing a hook according to the first embodiment, the hook body 37 is installed by connecting the lower ends of a pair of vertical frames 33 of the jamb 31. At an opening in the frame, for example, where the jamb 31 is to be attached, the floor surface 11 is cut to form a groove 13 in which the hook body 37 can be placed. Before the jamb 31 is placed, a fixing member 23 is set upright on the bottom surface 21 of the groove 13. In other words, an anchor pile is fixed and installed so that it stands upright from the bottom surface 21.

[0059] A plurality of anchor frame portions 25 are provided at predetermined intervals in the longitudinal direction on the underside 27 of the sheath body 37 attached to the jamb 31. The jamb 31 is fixed to the frame so that the sheath body 37 is positioned in a predetermined position in the groove 13. At this time, the sheath body 37 is fixed to the fixing member 23 erected on the bottom surface 21 by welding or the like.

[0060] With the jamb 31 and the mounting body 37 positioned and fixed in place, the groove 13 is filled with mortar 19. As the mortar 19 is filled, it flows into the groove 13 until it comes into close contact with the underside 27 of the mounting body 37. That is, the anchor frame 25 provided on the underside 27 and the fixed, hanging embedding portion 45 are simultaneously embedded in the mortar 19. The mortar 19 also embeds at least a portion of the side surface of the mounting body 37, excluding the top surface 15, and is finished to be approximately flush with the floor surface 11. That is, because the embedding portion 45, in addition to the anchor frame 25, is embedded in the mortar 19, a mounting structure can be obtained in which the mounting body 37 is firmly fixed to the mortar 19.

[0061] Therefore, the conventional construction method for the Kutsuri can eliminate the cumbersome work of turning the three-sided frame 31 upside down and filling the Kutsuri body 37 with mortar 19. After the three-sided frame 31 is delivered to the site and installed in the groove 13 through the erection process and fixing process, the construction can be completed simply by plastering work, which involves filling the mortar 19 in the mortar filling process.

[0062] Next, a modified example of the structure of the hook according to the first embodiment will be described.

[0063] FIG. 3 is a perspective view of a main part of a hook structure according to a first modified example of the first embodiment. In the structure of the shim according to Variation 1, the filler introduction section 39 is formed by a notch 47 cut out including the lower end of the side plate 41. That is, the notch 47 is generally comb-shaped, opening downward. The notch 47 is, for example, rectangular and formed across the side plate 41 in the vertical direction. Note that the notch 47 is preferably formed slightly below the upper surface 15 of the shim body 37 so that the rounded portion 29 remains on the upper surface 15. Multiple notches 47 are formed at predetermined intervals along the longitudinal direction of the shim body 37. Furthermore, it is preferable that the notches 47 formed in one side plate 41 and the notches 47 formed in the other side plate 41 are alternately arranged, i.e., not overlapping when the shim body 37 is viewed from the side. This allows the mortar 19 to flow smoothly and without impediment when filling the mortar 19.

[0064] According to this modification 1, the provision of a pair of side plate portions 41 ensures the rigidity of the threading body 37, while the notches 47 allow the mortar 19 to flow in smoothly, eliminating the occurrence of voids when filling with mortar. Also, by alternately arranging the notches 47 formed in the pair of side plate portions 41, the filling properties of the mortar 19 are improved, and the mortar 19 can be tightly attached to the underside 27 of the threading body 37. Furthermore, the pair of side plate portions 41 are embedded in the mortar 19, and the threading body 37 is fixed on both sides, making it less likely to peel off. The anchor frame portion 25 is fixed to the lower surface 27 of the hanging body 37 between the pair of side plate portions 41.

[0065] FIG. 4 is a perspective view of the main part of a hook structure according to the second modification of the first embodiment. In the structure of the string according to the second modification, the filler introduction section 39 is formed by a through hole 49 cut out of the side plate section 41. The through hole 49 is, for example, rectangular and is formed in the vertical center of the side plate section 41. The through holes 49 are formed at predetermined intervals in the longitudinal direction of the string body 37. Furthermore, it is preferable that the through holes 49 formed in one side plate section 41 and the through holes 49 formed in the other side plate section 41 are arranged alternately.

[0066] According to this second modification, by providing a pair of side plates 41, it is possible to ensure the rigidity of the threading body 37 while allowing the mortar 19 to flow in through the through holes 49. Because the through holes 49 are formed in the vertical center of the side plates 41, a decrease in the strength of the side plates 41 can be suppressed compared to the above-mentioned notch 47 formed almost vertically. Furthermore, by alternately arranging the through holes 49 formed in the pair of side plates 41, the filling properties of the mortar 19 can be improved, and the mortar 19 can be firmly adhered to the underside 27 of the threading body 37. Furthermore, since the pair of side plates 41 are embedded in the mortar 19, the threading body 37 is fixed on both sides, making it less likely to peel off. In this modified example 2, if a step occurs between the upper edge of the through hole 49 and the underside 27 of the link body 37, a member similar to the packing member 43 of the above-described embodiment can be placed and fixed to eliminate this step, which will improve the flow of mortar 19 and prevent the occurrence of voids. Also, the anchor frame 25 is fixed to the underside 27 of the link body 37 between the pair of side plate portions 41 in the same manner as above.

[0067] FIG. 5 is a cross-sectional view of a main part of a hook structure according to a third modification of the first embodiment. In the structure of the string according to the third modification, one of a pair of side plate portions 41 hangs down shorter than the other, and this shorter side plate portion 41 is folded back 180 degrees, a so-called hemming, to form a folded portion 51 that is superimposed on the underside 27. In the string main body 37, a steel stuffing member 43 is fixed to the underside 27 between one side plate portion 41 and this folded portion 51. This stuffing member 43 is, for example, a steel plate or the like having the same thickness as the folded portion 51.

[0068] According to this modification 3, the thickness of the upper surface 15 side can be reduced while maintaining the rigidity of the sliding body 37, and the rigidity is further improved by the filling member 43, making it less likely to become dented. In addition, the side plate portion 41 serves as the folded portion 51, which makes it easier for the mortar 19 to flow onto the lower surface 27 of the sliding body 37.

[0069] FIG. 6 is a cross-sectional view of a main part of a structure of a hook according to a fourth modification of the first embodiment. In the structure of the hanger according to the fourth modification, one of a pair of side plates 41 hangs down at a shorter length than the other. A stuffing member 43 having a convex curved surface 53 on the underside is fixed to the underside 27 of the hanger body 37 between one side plate 41 and the shorter side plate 41. The stuffing member 43 is made of steel, for example, but the material is not limited thereto. Preferably, the stuffing member 43 has a smooth upper surface that is in close contact with the hanger body underside 27, a solid lower surface with the convex curved surface 53, and an end portion formed on one side of the shorter side plate 41 with a thickness equal to the hanging length.

[0070] According to this fourth modification, since the packing member 43 has a downwardly convex curved surface 53, gaps are less likely to occur between the packing member 43 and the mortar 19 when the mortar 19 is being filled. In other words, the underside of the threading body 37 does not have a downward depression (recess) that the mortar 19 must flow around when flowing, and as a result, poor flow (filling) of the mortar 19, such as the formation of gaps on the underside 27 of the threading body 37, can be suppressed. In addition, since the threading body 37 can be configured to be thick, the rigidity of the threading body 37 can be increased, making it less likely to undergo depression deformation.

[0071] FIG. 7 is a cross-sectional view of a main part of a structure of a hook according to a fifth modified example of the first embodiment. In the structure of the stringer according to Variation 5, one of a pair of side plates 41 hangs down at a shorter length than the other. A flat-shaped stuffing member 43 is fixed to the underside 27 of the stringer body 37 between one side plate 41 and the shorter side plate 41. The stuffing member 43 is made of, for example, steel and is composed of multiple plates that are stacked to a thickness corresponding to the length of the shorter side plate 41 and fixed by welding or the like. An embedded portion 45 made of an inverted L-shaped angle bar is fixed to the underside of the stuffing member 43. The upper end of the embedded portion 45, which serves as a base, is fixed to the stuffing member 43 by welding or the like. The embedded portion 45 is formed, for example, in the shape of a narrow strip, and preferably multiple embedded portions 45 are provided at predetermined intervals along the longitudinal direction of the stringer body 37.

[0072] According to this modification 5, since the packing members 43 are provided on the lower surface 27, gaps are less likely to form between the packing members 43 and the mortar 19 when the mortar 19 is filled. Also, since the thickness of the upper surface 15 of the threading body 37 is increased, the threading body 37 is less likely to be deformed by denting. In addition, since the embedding portions 45 fixed to the lower surface 27 of the packing members 43 are embedded in the mortar 19, the integration with the mortar 19 is improved, making it less likely that the threading body 37 will peel off.

[0073] FIG. 8 is a cross-sectional view of a main part of a structure of a hook according to a sixth modified example of the first embodiment. The structure of the string according to the sixth modification is similar to that of the fifth modification, in that one of the pair of side plates 41 hangs down at a shorter length than the other. Furthermore, a flat-shaped stuffing member 43 is fixed to the underside 27 of the string body 37 between one side plate 41 and the shorter side plate 41. An embedded portion 45 made of a U-shaped or C-shaped angle bar is fixed to the underside of the stuffing member 43. The upper end of the embedded portion 45, which serves as the base, is fixed to the stuffing member 43 by welding or the like. The embedded portion 45 is formed, for example, in the shape of a narrow strip, and preferably multiple embedded portions 45 are provided at predetermined intervals along the longitudinal direction of the string body 37.

[0074] According to this sixth modification, the thickness of the upper surface 15 of the threading body 37 is increased by the packing member 43, making it more difficult for the threading body 37 to bend or deform. In addition, the C-shaped embedding portion 45 fixed to the lower surface 27 of the packing member 43 is embedded in the mortar 19, and the tip 46, which is the lower end of the embedding portion 45, is bent, which increases the resistance (strength) of the threading body 37 in the pull-out direction, making it more difficult for the threading body 37 to bend or deform.

[0075] Next, a second embodiment will be described.

[0076] 9 is a cross-sectional view of the structure of the hook according to the second embodiment, taken along a direction perpendicular to the extending direction of the groove 13. In the second embodiment, the same or equivalent members and parts as those shown in FIGS. 1 to 8 are designated by the same reference numerals, and redundant explanations will be omitted. The structure of the slipcase according to the second embodiment includes a slipcase body 55 having a long, strip-shaped upper surface 15, a groove 13 formed by cutting into the floor surface 11 with a width wider than the width of the slipcase body 55, and the slipcase body 55 is placed inside the groove 13, and mortar 19 filled into the groove 13 with the upper surface 15 of the slipcase body 55 exposed.

[0077] A fixing member 23 is erected on the bottom surface 21 of the groove 13. The fixing member 23 is, for example, an anchor pile or a reinforcing bar, and is installed by being driven perpendicularly into the bottom surface 21 after the groove 13 is formed.

[0078] The hook body 55 is made of, for example, steel, and has a pair of side plate portions 41 hanging down from each of a pair of long sides of the top surface 15. Each side plate portion 41 is formed with a sufficiently short length in the hanging direction. These side plate portions 41 may be bent in the hanging direction perpendicular to the top surface 15 as shown in FIG. 9, or may be folded back, for example, by 180°, a so-called hemming bend, to form a folded portion 51 with a short folding margin as shown in FIG. 10(b). In other words, the edge of the top surface 15 becomes a reinforced edge portion with a thick structure.

[0079] A fixing protrusion 59 that protrudes downward is provided between the pair of side plate portions 41. This fixing protrusion 59 is fixed to the fixing member 23. The fixing protrusion 59 can be formed using, for example, an L-shaped or angled angle iron. Note that a flat stuffing member 43 may be sandwiched between this fixing protrusion 59 and the chain body 55.

[0080] In this embodiment, as shown in FIG. 9 , the fixing protrusion 59 is configured by fixing one vertical piece of a pair of angle bars back-to-back in a T-shape. The T-shaped fixing protrusion 59 has a pair of horizontal upper pieces 61 fixed to the stuffing member 43. Therefore, the pair of back-to-back vertical pieces form the fixing protrusion 59 and hang down from the center of the width of the hanging body 55. The width of the pair of upper pieces 61 is set to the spacing between the pair of side plate portions 41, and together with the stuffing member 43, they fill the space between the side plate portions 41. The fixing protrusion 59 is welded to the fixing member 23. In this embodiment, the pair of side plate portions 41 are formed short and hanging down. This creates large filler introduction openings 39 on both sides of the fixing protrusion 59 between the side plate portion 41 and the bottom surface 21.

[0081] 10(a) is a cross-sectional view of a belt body 55 to which a single fixing protrusion 59 is fixed, and FIG. 10(b) is a cross-sectional view of a belt body 55 to which two fixing protrusions 59 are fixed. 10(a), the L-shaped or angle-shaped fixing protrusion 59 may be a single angle bar. In this case, the upper piece 61 may also serve as the stuffing member 43, and the stuffing member 43 is provided on the underside 27 between the fixing protrusion 59 and the side plate 41. 10(b), the pair of side plate portions 41 of the hemming body 55 may be folded back 180 degrees, so-called hemming, and then overlapped on the lower surface 27. The hemming body 55 has a T-shaped fixing protrusion 59 of the shape shown in FIG. 9 fixed to the lower surface 27 between the pair of folded back portions 51. In this case, the hemming body 55 may omit the stuffing member 43.

[0082] In this structure of the shoe rack, at least a portion of the side of the side panel portion 41 excluding the top surface 15 of the shoe rack main body 55 and the fixing protrusion 59 are embedded in mortar 19 filled in the groove 13 so as to be flush with the floor surface 11.

[0083] Next, the operation of the second embodiment will be described.

[0084] In this structure of a slip-on, a slip-on body 55 is placed in a groove 13 formed by chipping the floor surface 11. The slip-on body 55 has a rectangular upper surface 15 that is narrower than the width of the groove 13 and long along the groove 13. The groove 13 in which the slip-on body 55 is placed is filled with mortar 19. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the mortar 19 is filled.

[0085] In this structure of the shaft, shaft body 55 has a pair of side plates 41 hanging down from each of a pair of long sides of top surface 15. The distance between side plates 41 in the hanging direction is sufficiently small, so the area below side plates 41 becomes filler introduction section 39, allowing mortar 19 to pass through smoothly.

[0086] The width of the board in the direction perpendicular to the longitudinal direction of the shim body 55 is narrower than the groove width, so in the groove 13 in which the shim body 55 is placed, a mortar filling opening 35 is formed between the groove opening and the shim body 55. Mortar 19 is poured from this mortar filling opening 35 below the shim body 55.

[0087] The slider body 55 is provided with a fixing projection 59 between the pair of side plates 41, which protrudes downward and is fixed to the fixing member 23. A stuffing member 43 is provided between the pair of side plates 41 and the fixing projection 59. The slider body 55 has the fixing projection 59 fixed to the fixing member 23 erected on the bottom surface 21 by welding or the like. Therefore, in this state, the slider body 55 is positioned relative to the groove 13 and floor surface 11. The positioned slider body 55 is arranged so that the top surface 15 is flush with or higher than the floor surface 11 and the finishing surface 20, for example, by about 3 mm.

[0088] The mortar 19 filled into the groove 13 from the mortar filling opening 35 passes under the side plate portion 41 and is filled in contact with the filling member 43 provided on the underside 27 of the sliding body 55. In other words, no gap is created between the underside 27 of the sliding body 55 and the mortar 19. By filling the groove 13 flush with the floor surface 11, the mortar 19 embeds at least a portion of the side surface of the sliding body 55 in the thickness direction, excluding the top surface 15, and the fixing protrusions 59.

[0089] In this structure of the slide, slide body 55 has a pair of side plates 41 that hang down into groove 13, and a filling member 43 and an upper piece 61 are provided between these side plates 41. Therefore, the underside of slide body 55 does not have a downward depression (recess) that mortar 19 must flow around when flowing. As a result, poor flow (filling) of mortar 19, such as the formation of voids on the underside of slide body 55, can be suppressed. In other words, mortar 19 can be easily poured onto the underside of slide body 55. As mortar 19 flows into underside 27 of slide body 55, and fixing protrusions 59 fixed to fixing members 23 are embedded in mortar 19, slide body 55 is firmly and strongly fixed to the framework. This allows the mortar 19 to flow onto the underside 27 of the mortar body 55 without leaving any gaps, thereby allowing the mortar 19 to be fixed to the underside 27 of the mortar body 55.

[0090] In addition, it eliminates the need for mortar filling, which is required only for the mortaring work in conventional structures. This means that plastering work and fitting work are not intertwined, making construction work smoother and shortening the construction period.

[0091] Furthermore, because the fixing projections 59 protrude from the underside of the sliding body 17 as a single piece, the flow of the mortar 19 is not impeded when the mortar 19 is poured in from both sides of the sliding body 55, and the fixing projections 59 can be embedded while preventing gaps from forming between the underside 27 of the sliding body 55 and the mortar 19, ensuring the fixing strength of the sliding body 55. Also, because the side plate portions 41 hanging down from the long sides of the sliding body 55 are shortened to a distance approximately equal to the plate thickness, a large mortar filling space is opened between the sliding body 55 and the bottom surface 21 of the groove 13, allowing the mortar 19 to flow in smoothly.

[0092] Next, a third embodiment will be described. Fig. 11 is a perspective view showing a splice structure according to a third embodiment, and Fig. 12 is a cross-sectional view in a direction perpendicular to the extending direction of the grooves in the splice structure shown in Fig. 11. In the third embodiment, members and parts that are the same as or equivalent to those shown in Figs. 1 to 10 are designated by the same reference numerals, and redundant explanations will be omitted.

[0093] The structure of the rung according to the third embodiment comprises a rung body 17 having a long, strip-shaped upper surface 15, a groove 13 cut into the floor surface 11 with a width wider than the width of the rung body 17 and inside which the rung body 17 is placed, and mortar 19 filled into the groove 13 with the upper surface 15 of the rung body 17 exposed. A fixing member 23 is erected on the bottom surface 21 of the groove 13.

[0094] In the structure of the helix according to the third embodiment, the helix body 17 is formed in a flat plate shape. That is, it does not have the side plate portions 41 shown in the above-described embodiments. The helix body 17 is preferably made of a material such as steel, stainless steel, or aluminum. An upwardly opening, U-shaped anchor frame 25 is fixed to the underside 27 of the sheath body 17. The anchor frame 25 is made of, for example, steel. Steel is a suitable steel material. The anchor frame 25 is attached to the sheath body 17 perpendicular to the longitudinal direction of the sheath body 17. Each anchor frame 25 is formed by bending a narrow, rectangular plate-like member. Its width is sufficiently shorter than the longitudinal length of the sheath body 17. A plurality of anchor frames 25 are attached to the sheath body 17, spaced apart from each other along the longitudinal direction. The spacing between each anchor frame 25 is determined according to the length of the sheath body 17. For example, if the sheath body 17 is approximately 900 mm long, three anchor frames 25 are provided: one approximately 150 mm from each end of the sheath body 17 and another approximately 300 mm apart from the other end. The anchor frame 25 is fixed to a fixing member 23 erected on the bottom surface 21 of the groove 13. That is, the position of the fixing member 23 is also set to the spacing position of the above-mentioned dimension. The anchor frame 25 and the fixing member 23 can be fixed together by, for example, welding or fastening using threaded means (screws, bolts, etc.).

[0095] In the structure of the third embodiment, the top surface 15 of the hook body 17 is flush with or elevated above the floor surface 11. In this hook structure, at least a portion of the side surface in the thickness direction, excluding the top surface 15, and the anchor frame portion 25 are embedded in mortar 19 filled in the groove 13 so as to be flush with the floor surface 11.

[0096] The lathe body 17 preferably has a rounded portion 29 where the corner where the side surface in the thickness direction intersects with the top surface 15 is chamfered. The lathe body 17 protrudes from the floor surface 11 by about 3 mm. Therefore, the rounded portion 29 can have a radius of about 3 mm.

[0097] The construction method for the kutsusuri in the third embodiment includes a chipping process, a fixing part installation process, a construction process, a fixing process, and a mortar filling process, and is almost the same as the construction methods for the kutsusuri in the first and second embodiments.

[0098] In the chipping process, the floor surface 11 is chipped to form the groove 13. The groove 13 has a width larger than the width of the board of the hook body 17, and preferably larger than the width of the vertical frame 33 that makes up the three-sided jamb, as shown in Figure 12. The groove 13 accommodates the anchor frame part 25 and is formed to a depth such that the top surface 15 of the hook body 17 is flush with the floor surface 11 or protrudes by about 3 mm.

[0099] In the fixing portion installation process, fixing members 23 are provided on the bottom surface 21 at predetermined intervals in the extension direction of the groove 13, for example, at intervals of 300 mm, according to the length of the strap body 17 and corresponding to the position of the anchor frame portion 25.

[0100] The erection process is performed by erecting the three-sided jamb into the groove 13. The three-sided jamb has a pair of parallel, spaced-apart vertical frames 33 whose upper ends are connected by an upper frame (not shown). The sliding frame body 17 is installed with the lower ends of the vertical frames 33 of this three-sided jamb connected to each other. In other words, the installation of the sliding frame body 17 makes the three-sided jamb a square frame (four-sided frame). In the erection process, the three-sided jamb with the sliding frame body 17 attached is erected so that the sliding frame body 17 is positioned in a predetermined position in the groove 13. In other words, the three-sided jamb and sliding frame body 17 are erected in the determined predetermined positions and fixed to the frame side.

[0101] In the fixing step, the anchor frame portion 25 provided on the lower surface 27 of the strap body 17 is fixed to the fixing member 23. The fixing means is, for example, welding.

[0102] In the mortar filling process, mortar 19 is filled into the groove 13 in which the base body 17 is placed so as to form a finished surface 20 that is flush with the floor surface 11. The mortar 19 is embedded into at least a portion of the side of the base body 17, excluding the top surface 15 of the base body 17, as well as the anchor frame portion 25 and the embedding portion 45. The mortar 19 filled into the groove 13 is allowed to harden while in close contact with the underside 27 of the base body 17. After curing for a predetermined time, the mortar 19 hardens, and the mortar 19 and base body 17 become one, completing the installation of the base.

[0103] Next, the operation of the third embodiment will be described.

[0104] In the structure of the slipstop according to the third embodiment, a slipstop body 17 is placed in a groove 13 formed by chipping the floor surface 11. The groove 13 is wider than the length of the slipstop body 17. The slipstop body 17 is made of a material such as steel, stainless steel, or aluminum, and has an upper surface 15 in the shape of a rectangular strip that is narrower than the width of the groove 13 and extends along the groove 13. The groove 13 in which the slipstop body 17 is placed is filled with mortar 19. A fixing member 23 is erected on the bottom surface 21 of the groove 13 before the mortar 19 is filled.

[0105] The width of the board in the direction perpendicular to the longitudinal direction of the shim body 17 is narrower than the groove width of the groove 13, so that in the groove 13 in which the shim body 17 is placed, a mortar filling opening 35 is formed between the groove opening and the shim body 17. Mortar 19 is poured below the shim body 17 from the mortar filling openings 35 on both sides of the shim body 17.

[0106] The chamfer body 17 has an upwardly opening U-shaped anchor frame 25 fixed to the underside 27. This anchor frame 25 is fixed by welding or the like to a fixing member 23 erected on the bottom surface 21. Therefore, in this state, the chamfer body 17 is positioned relative to the groove 13 and floor surface 11. The positioned chamfer body 17 is placed so that the upper surface 15 is flush with or higher (for example, about 3 mm) than the floor surface 11.

[0107] The mortar 19 filled into the groove 13 from the mortar filling opening 35 passes through the filler introduction section 39 and is filled in contact with the underside 27 of the anchor body 17. In other words, the underside of the anchor body 17 does not have any downward depressions (concave sections) that the mortar 19 would have to flow around when it flows in, and the mortar 19 is filled without creating any gaps between the smooth underside 27 of the anchor body 17 and the mortar 19. The mortar 19 is flush with the floor surface 11, forming the finished surface 20, and by filling the groove 13, it embeds at least a portion of the side surface of the anchor body 17 in the thickness direction, excluding the top surface 15, as well as the anchor frame section 25 and the embedding section 45.

[0108] In this structure of the anchor, the anchor body 17 is flat, which makes it easy to smoothly pour the mortar 19 onto the underside of the anchor body 17. The mortar 19 flows onto the underside 27 of the anchor body 17, and the anchor frame portion 25 and embedding portion 45 fixed to the fixing member 23 are embedded in the mortar 19, so the anchor body 17 is firmly fixed to the frame with high strength. This allows the mortar 19 to be filled into the underside 27 of the anchor body 17 without any gaps, and the underside 27 of the anchor body 17 and the mortar 19 to be firmly fixed together.

[0109] In addition, it eliminates the need for mortar filling, which is required only for the mortaring work in conventional structures. This means that plastering work and fitting work are not intertwined, making construction work smoother and shortening the construction period.

[0110] Furthermore, since a plurality of anchor frame portions 25 are provided at predetermined intervals in the longitudinal direction of the threading body 17, the flow of the mortar 19 is less likely to be impeded, and gaps are less likely to occur between the underside 27 of the threading body 17 and the mortar 19, while the fixing strength of the threading body 17 can be ensured.

[0111] In this structure, a flat slide body 17 is placed in a groove 13 formed by cutting into the floor surface 11. The groove 13 is filled with mortar 19, flush with the floor surface 11. The mortar 19 is embedded in at least a portion of the side surface of the slide body 17 in the thickness direction, excluding the top surface 15. As a result, the top surface 15 of the slide body 17 is not flush with the finished surface 20 of the mortar 19, and the corner where the side surface of the slide body 17 in the thickness direction and the top surface 15 intersect forms a step that protrudes upward from the finished surface 20 of the mortar 19. This step, which is about 3 mm, for example, will collide with heavy fixtures and the like when they pass through. This may cause the slide body 17 to curl up. In the shoe structure, these corners are chamfered to form rounded sections 29, which can reduce the external force acting on the shoe body 17 when it comes into contact with something, preventing the shoe body 17 from curling up. It also makes it less likely for pedestrians to get caught when passing through. As a result, the upper surface 15 of the shoe body 17, which protrudes from the mortar finished surface 20, has rounded sections 29, and the steps created by these rounded sections 29 are smooth, making it less likely for people to trip over them.

[0112] Furthermore, in the construction method for a hook according to the third embodiment, the hook body 17 is installed by connecting the lower ends of a pair of vertical frames 33 of the three-sided jamb. At an opening in the frame, for example, where the three-sided jamb is to be attached, a groove 13 is pre-installed in advance by cutting the floor surface 11, into which the hook body 17 can be placed. Before the three-sided jamb is placed, a fixing member 23 is pre-installed on the bottom surface 21 of the groove 13. That is, an anchor pile or the like is fixed and installed so that it stands up from the bottom surface 21.

[0113] A plurality of anchor frames 25 are provided at predetermined intervals in the longitudinal direction on the underside 27 of the sheath body 17 attached to the jamb. The sheath body 17 is fixed to the frame so that it is positioned in a predetermined position in the groove 13. At this time, the sheath body 17 is fixed to a fixing member 23 erected on the bottom surface 21 by welding or the like.

[0114] With the jamb and the main frame 17 positioned and fixed in place, the groove 13 is filled with mortar 19. As the mortar 19 is filled, it flows into the groove 13 until it comes into close contact with the underside 27 of the main frame 17. In other words, it embeds the anchor frame portion 25 and the embedding portion 45 provided on the underside 27. The mortar 19 also embeds at least a portion of the side of the main frame 17, excluding the top surface 15, and is finished so that it is approximately flush with the floor surface 11.

[0115] Therefore, the conventional construction method for Kutsuzuri eliminates the cumbersome work of turning the three-sided frame upside down and filling the Kutsuzuri body with mortar 19. After the three-sided frame is delivered to the site and installed in the groove 13 through the erection process and fixing process, construction can be completed simply by filling the groove 13 with mortar 19 in the mortar filling process.

[0116] Therefore, the structure of the mortar wall according to this embodiment eliminates the need to turn the mortar wall upside down and fill it only with mortar, thereby shortening the construction period.

[0117] Furthermore, the construction method for the Kutsuzuri according to this embodiment eliminates the need for the cumbersome work of turning the frame upside down to which the Kutsuzuri body 17 (37, 55) is fixed, filling the Kutsuzuri only with mortar 19, and then turning the frame upside down again and erecting it after the mortar has hardened. This eliminates the need for intertwining plastering work and fitting work, making construction work smoother and shortening the construction period. [Explanation of symbols]
