Description

[Technical field]

[0001] The present disclosure relates to construction turnbuckles. [Background technology]

[0002] As an example of a conventional architectural turnbuckle, as shown in Non-Patent Document 1, there is disclosed an architectural turnbuckle that includes a turnbuckle body that adjusts the longitudinal length, and turnbuckle bolts that are attached to both longitudinal sides of the turnbuckle body, with a shuttlecock-shaped plate member provided at the tip of the turnbuckle bolt. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] "JIS A 5540:2008 Turnbuckles for Construction", Japan Standards Association, October 20, 2008 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the architectural turnbuckle of Non-Patent Document 1, a shuttlecock-shaped plate member is attached to one side of the mounting part on the frame side, so the rod-shaped part of the turnbuckle bolt and the mounting part on the frame side are offset in the thickness direction of the shuttlecock-shaped plate member. Therefore, when the architectural turnbuckle is used, bending stress is applied to the rod-shaped part and the mounting part, and it may be difficult to select bolts and nuts for mounting that can withstand the load, so there is room for improvement in these respects.

[0005] An object of the present disclosure is to provide a turnbuckle for construction that is less likely to generate bending stress in the mounting portion. [Means for solving the problem]

[0007] In addition, the construction turnbuckle of the present invention is [2] In the configuration described in [1] above, it is preferable that only one hole is formed at approximately the same position in a plan view in each of the plate-like members arranged to be approximately parallel to each other.

[0008] In addition, the construction turnbuckle of the present invention is [3] In the configuration described in [1] or [2] above, it is preferable that the mounting portion of each of the turnbuckle bolts has two plate-shaped members, each of the plate-shaped members has a roughly rectangular cutout portion at its base end, the outer peripheral surface of the tip of the rod-shaped connecting portion is fixed to an edge portion extending in the longitudinal direction of the architectural turnbuckle at the cutout portion, and the two plate-shaped members are arranged in symmetrical positions in the vertical direction with respect to the central axis.

[Figure 5B] 1 is an example of a frame equipped with a construction turnbuckle according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a construction turnbuckle 100 according to an embodiment of the present disclosure will be described in detail with reference to the drawings (FIGS. 1A to 5B).

[0012] The architectural turnbuckle 100 of this embodiment is a diagonal brace that spans across a frame, which is the framework of a building, for example, consisting of column members and beam members, and is a reinforcing member in which the connection parts 2 of the turnbuckle bolts 10 are attached to both longitudinal ends of the turnbuckle body 1 in a length-adjustable state, and a flat mounting part 20, also known as a shuttlecock, is fixed to the tip of the connection part 2.

[0013] As shown in Fig. 1A etc., the architectural turnbuckle 100 comprises a turnbuckle body 1 that is operated by an operator when adjusting the length of the architectural turnbuckle 100 in the longitudinal direction (left and right direction, X direction in Fig. 1A), and turnbuckle bolts 10 that are attached to both longitudinal ends of the turnbuckle body 1. The turnbuckle bolt 10 is attached to the turnbuckle body 1 at the male thread portion 2b of the connection portion 2 provided on the turnbuckle body 1 side in the longitudinal direction, and is movable in the longitudinal direction by rotating about the central axis O of the turnbuckle body 1.

[0014] In this specification, claims, and drawings, the up-down direction of the architectural turnbuckle 100 is the direction perpendicular to the paper surface in the plan view of FIG. 1A (Z direction), and the up-down direction in the front view of FIG. 1B. The central axis O of the architectural turnbuckle 100 extending in the left-right direction (X direction) of FIG. 1A coincides with the central axis of the connecting part 2 provided in a round bar shape. The width direction of the architectural turnbuckle 100 is the up-down direction (Y direction) in FIG. 1A, and the direction perpendicular to the paper surface in FIG. 1B. The side closer to the turnbuckle body 1 in the longitudinal direction (X direction) may be called the base end, and the side farther from the turnbuckle body 1 may be called the tip.

[0015] In this embodiment, the names of the architectural turnbuckle 100, the turnbuckle body 1, and the turnbuckle bolt 10 are the same as those of the architectural turnbuckle, the turnbuckle body, and the turnbuckle bolt specified in JIS A 5540:2008, JIS A 5541:2008, and Annex A of JIS A 5540:2008. However, the architectural turnbuckle 100 and the turnbuckle bolt 10 differ from those of JIS A 5540:2008 and Annex A of JIS A 5540:2008 in that the mounting part 20 has at least a plurality of plate-shaped members. In addition, the configuration of the turnbuckle body 1 may be a configuration conforming to JIS A 5541:2008, or may be a configuration not conforming to JIS A 5541:2008 as long as there is no problem in mounting the turnbuckle bolt 10.

[0016] The accompanying drawings of the present disclosure are drawn to the same scale in the vertical direction (Z direction), the longitudinal direction (X direction), and the width direction (Y direction), and the aspect ratio of the architectural turnbuckle 100 in the drawings represents the aspect ratio of the architectural turnbuckle 100 of one embodiment of the present disclosure. However, the configuration, shape, dimensional ratio, etc. of the architectural turnbuckle 100 in the accompanying drawings are merely one embodiment of the present disclosure. The present invention should be interpreted based on the wording of the claims, and is not limited to the configuration, shape, dimensional ratio, etc. shown in the drawings.

[0017] The turnbuckle body 1 is also called a split frame type, and as shown in FIG. 1A, it has two gripping parts 1a extending in the longitudinal direction and spaced apart in the width direction, a threaded cylindrical part 1b connected to both longitudinal ends of the gripping part 1a, and a female threaded part 1c provided on the inner surface of the threaded cylindrical part 1b. By providing the two gripping parts 1a in the width direction spaced apart from each other by more than the outer diameter of the threaded cylindrical part 1b as shown in FIG. 1A, a larger rotational moment can be applied by an operator by gripping the gripping part 1a and rotating it around the central axis O. Therefore, the turnbuckle body 1 can be rotated with a smaller force to adjust the length in the longitudinal direction. The female threaded part 1c of the turnbuckle body 1 is configured to be screwed into the male threaded part 2b provided on the turnbuckle body 1 side of the connecting part 2 provided in a round bar shape described later.

[0018] The connection part 2 is a rod-shaped member whose base end is attached to the turnbuckle body 1 and whose tip end is fixed to the attachment part 20. The connection part 2 has a substantially circular cross section and includes a rod-shaped part 2a provided on the attachment part 20 side and extending in the longitudinal direction, and a male screw part 2b provided on the turnbuckle body 1 side. The connection part 2 may be a solid member or an annular member. In addition, the cross-sectional shape of the rod-shaped part 2a is not limited to a circular shape, and may be an elliptical shape, a rectangular shape, or the like.

[0019] The male thread portion 2b provided on the connection portion 2 of the turnbuckle bolt 10 on the right side of FIG. 1A (right-handed turnbuckle bolt 11R) is a right-handed thread, and the male thread portion 2b provided on the connection portion 2 of the turnbuckle bolt 10 on the left side of FIG. 1A (left-handed turnbuckle bolt 11L) is a left-handed thread. With this configuration, by rotating the turnbuckle body 1 so that the upper grip portion 1a of FIG. 1A moves toward the front side of the paper, both the left and right connection portions 2 can be moved in a direction approaching the turnbuckle body 1. Therefore, the length can be adjusted so that the longitudinal length from the longitudinal center position of the turnbuckle body 1 to the tip of each turnbuckle bolt 10 becomes shorter. On the other hand, by rotating the turnbuckle body 1 so that the upper grip portion 1a of FIG. 1A moves toward the back side of the paper, both the left and right connection portions 2 can be moved in a direction away from the turnbuckle body 1. Therefore, the length can be adjusted so that the longitudinal length from the longitudinal center position of the turnbuckle body 1 to the tip of each turnbuckle bolt 10 is long.

[0020] In this embodiment, the longitudinal lengths of the rod-shaped portion 2a not provided with a male thread and the male thread portion 2b in the connection portion 2 are configured to be approximately equal, but this is not limited to the embodiment. The ratio of the longitudinal lengths of the rod-shaped portion 2a and the male thread portion 2b can be appropriately determined based on the longitudinal length adjustment range required for the construction turnbuckle 100, etc.

[0021] In addition, the mounting portion 20 that constitutes the architectural turnbuckle 100 includes a flat base plate portion 21 (plate-shaped member), a cutout portion 23 that is approximately rectangular in plan view and is provided at the base end (the turnbuckle body portion 1 side) of the base plate portion 21, and a hole portion 22 for fixing the architectural turnbuckle 100 to the mounting portion 50 on the frame side.

[0022] As shown in Fig. 1B, the two substrate parts 21 are arranged vertically so as to be substantially parallel to each other. As shown in Fig. 1A, the cutout part 23 of the substrate part 21 extends in the longitudinal direction (the left-right direction in Fig. 1A), and the outer peripheral surface of the rod-shaped part 2a of the connection part 2 is welded and fixed to the edge part extending in the longitudinal direction of the cutout part 23 (see Fig. 1C). Note that the substrate part 21 and the rod-shaped part 2a may be configured to be fixed to each other by a method other than welding as long as the fixing strength is equal to or greater than a predetermined level.

[0023] That is, as shown in Fig. 1C, the upper (Z direction positive side) substrate portion 21 of the mounting portion 20 is welded and fixed to the notch portion 23 of the substrate portion 21 via the weld portion W at two points on the outer circumferential surface above the central axis O of the rod-shaped portion 2a of the connection portion 2. Similarly, the lower (Z direction negative side) substrate portion 21 of the mounting portion 20 is welded and fixed to the notch portion 23 of the substrate portion 21 via the weld portion W at two points on the outer circumferential surface below the central axis O of the rod-shaped portion 2a of the connection portion 2. In this embodiment, the two substrate portions 21 are arranged at symmetrical positions in the up-down direction with respect to the central axis O of the construction turnbuckle 100 and the connection portion 2, as shown in Figs. 1B and 1C.

[0024] In this embodiment, the two base plate parts 21 are arranged at symmetrical positions in the vertical direction with respect to the central axis O of the connection part 2 of the turnbuckle bolt 10. In other words, the center of gravity of the two base plate parts 21 is located on the central axis O of the connection part 2. For this reason, as shown in FIG. 1B, when a mounting part 50 called a gusset on the frame side is arranged in the space between the two base plate parts 21 and the mounting part 50 is fastened with a high-strength bolt 31 and a fastening nut 32, the height position of the mounting part 50 (the central height position of the mounting part 50) and the height position of the mounting part 20 (the height position at an equal distance from the two base plate parts 21) both coincide with the height position of the central axis O (i.e., the height position of the architectural turnbuckle 100). Therefore, even if a tensile stress or a compressive stress is applied in the longitudinal direction of the architectural turnbuckle 100, it is possible to make it difficult for bending stress to occur in the mounting part 20 and the mounting part 50 on the frame side. Therefore, since the load on the high-strength bolt 31 and the fastening nut 32 can be suppressed, the range of selection of the high-strength bolt 31 and the fastening nut 32 can be expanded. In addition, instead of the high strength bolt 31, for example, a hexagonal bolt having a strength class of 10.9 may be used.

[0025] The two base plate parts 21 may be provided at heights slightly shifted from positions symmetrical in the up-down direction with respect to the central axis O of the connection part 2 of the turnbuckle bolt 10. Also, the height position of the mounting part 50 and the height position of the attachment part 20 do not have to completely coincide with the height position of the central axis O (i.e., the height position of the construction turnbuckle 100).

[0026] In this embodiment, the nominal diameter of the male thread portion 2b and the female thread portion 1c may be selected from, for example, M24, M27, M30, and M33. Also, a nominal diameter different from the above may be adopted.

[0027] In this embodiment, the materials used are mainly JIS standard materials, but are not limited to these. For example, the materials used for the connection part 2 may be SNR400B or SNR490B, which are rolled bar steel for architectural structures, but are not limited to these.

[0028] 2 shows a construction turnbuckle 200 which is a modified example of one embodiment of the present disclosure. The construction turnbuckle 200 which is a modified example is similar to the one embodiment except that the shape of the turnbuckle body 101 is different from that of the one embodiment shown in FIG 1A. Therefore, the following description will focus on the differences from the one embodiment.

[0029] The construction turnbuckle 200 according to the modified example includes a turnbuckle body 101, also called a pipe type, and a turnbuckle bolt 10 attached to both longitudinal ends of the turnbuckle body 101. The tip of the turnbuckle bolt 10 is provided with an attachment part 20 for fixing the construction turnbuckle 200 to the mounting part 50 on the frame side.

[0030] As shown in FIG. 2, the turnbuckle body 101 includes a cylindrical gripping portion 101a extending in the longitudinal direction, a threaded cylindrical portion 101b connected to both longitudinal ends of the gripping portion 101a, and a female threaded portion 101c provided on the inner surface of the threaded cylindrical portion 101b. By making the outer diameter of the cylindrical gripping portion 101a larger than the outer diameter of the threaded cylindrical portion 101b as shown in FIG. 2, a larger rotational moment can be applied by an operator gripping the gripping portion 101a and rotating it around the central axis O. Therefore, the turnbuckle body 101 can be rotated with a smaller force to adjust the length in the longitudinal direction. The female threaded portion 101c of the turnbuckle body 101 is configured to be threadedly engaged with the male threaded portion 2b provided on the turnbuckle body 101 side of the connecting portion 2 provided in a round bar shape.

[0031] FIG. 3A is an example of a frame 300 to which the architectural turnbuckle 100 according to this embodiment is attached. In the frame 300, a building framework formed by two pillar members 51 extending in the vertical direction in the figure when viewed from the front and a beam member 52 horizontally spanning between the upper portions of the pillar members 51 is formed on a foundation portion 54. The foundation portions 54 are connected to each other in the horizontal direction by a foundation beam 53, which suppresses the rotation and horizontal movement of the pillar members 51. In this embodiment, the foundation portion 54 and the foundation beam 53 are formed of reinforced concrete. As shown in FIG. 3A and other figures, the architectural turnbuckle 100 according to this embodiment is diagonally spanned across the pillar members 51 and the beam members 52 to form a brace, thereby increasing the resistance of the frame 300 to external forces such as earthquakes and typhoons. In the illustrated example, the architectural turnbuckle 100 is diagonally spanned between the mounting part 50a fixed by welding or the like to the lower part of the column member 51 on the left side of the figure and the mounting part 50b fixed to the right end part of the beam member 52 on the upper side of the figure. Similarly, the architectural turnbuckle 100 is diagonally spanned between the mounting part 50a fixed by welding or the like to the lower part of the column member 51 on the right side of the figure and the mounting part 50b fixed to the left end part of the beam member 52 on the upper side of the figure. The two architectural turnbuckles 100 are attached to the frame 300 with an appropriate tension by the worker adjusting the rotation of the turnbuckle body 1.

[0032] FIG. 3B is an example of a frame 400 to which the architectural turnbuckle 100 according to this embodiment is attached. The frame 400 is a building framework formed of two pillar members 51 extending vertically in the front view and two beam members 52 horizontally spanning the upper and lower parts of the pillar members 51. In this example, the foundation beam 53 as shown in FIG. 3A is not used, and the lower end of the pillar member 51 is fixed to the foundation. As shown in FIG. 3B and other figures, the architectural turnbuckle 100 according to this embodiment is diagonally spanned across the pillar member 51 and the beam member 52 to form a brace, thereby increasing the resistance of the frame 300 to external forces such as earthquakes and typhoons. In the example shown in the figure, the architectural turnbuckle 100 is spanned diagonally between the mounting part 50a fixed by welding or the like to the lower part of the pillar member 51 on the left side of the figure and the mounting part 50b fixed to the right end of the beam member 52 on the upper side of the figure. Similarly, an architectural turnbuckle 100 is diagonally spanned between mounting part 50a fixed by welding or the like to the lower part of the pillar member 51 on the right side of the figure, and mounting part 50b fixed to the left end part of the beam member 52 on the upper side of the figure.

[0033] Here, a method of fixing the mounting part 20 to the mounting parts 50 (50a, 50b) will be described. The mounting parts 50 (50a, 50b), also called gussets, are delivered to the construction site in a state in which they are fixed to the column member 51 or the beam member 52 by welding in advance. After temporarily assembling the frame 300, 400, the worker fixes the mounting parts 20 provided at both ends of the architectural turnbuckle 100 to the mounting parts 50 (50a, 50b) of the column member 51 or the beam member 52. The mounting part 20 is fixed to the mounting part 50 by disposing the mounting part 50 on the frame 300, 400 side in the space between the two base plate parts 21, as shown in FIG. 1B, and fastening the mounting part 20 and the mounting part 50 with the high-strength bolt 31 and the fastening nut 32. In this embodiment, the mounting part 22 is provided in only one place on each base plate part 21 of the mounting part 20 at approximately the same position in a plan view. Then, by fastening the high-strength bolt 31 so that it penetrates the hole portion 22 of each base portion 21 and the hole on the mounting portion 50 side, the architectural turnbuckle 100 can be attached to the mounting portion 50 at any mounting angle with the hole portion 22 as the center of rotation, as shown by the arrow in Figure 4.

[0034] With the above configuration, even if the mounting angle of the architectural turnbuckle 100 changes due to changes in the spacing between the column members 51 or the spacing between the beam members 52, the architectural turnbuckle 100 can be mounted to the mounting part 50 at any mounting angle with the hole 22 as the center of rotation. Therefore, there is no need to change the specifications of the mounting part 50 for each specification of the frame 300, 400, and a common mounting part 50 can be applied to multiple types of frame 300, 400 with different specifications.

[0035] In addition, since only one hole 22 is arranged on one base plate 21 of the mounting part 20, there is also only one hole on the side of the mounting part 50 (gusset) that is attached to the base plate 21. This makes it possible to reduce the size of the mounting part 50. This configuration makes it possible to improve the transportation efficiency of the column members 51 and beam members 52 to which the mounting parts 50 are welded, which are brought to the construction site.

[0036] FIG. 5A is another example of a frame 500 to which the architectural turnbuckle 100 according to this embodiment is attached. In the frame 500, a building framework formed by three pillar members 51, 51a extending in the vertical direction in the front view and a beam member 52 horizontally spanning between the upper portions of the pillar members 51, 51a is formed on a foundation 54. The foundation members 54 are connected to each other horizontally by a foundation beam 53, which suppresses the rotation and horizontal movement of the pillar members 51, 51a. In this embodiment, the foundation 54 and the foundation beam 53 are also formed of reinforced concrete. As shown in FIG. 5A and other figures, the architectural turnbuckle 100 according to this embodiment is diagonally spanned across the pillar members 51, 51a and the beam member 52 to form a brace, thereby increasing the resistance of the frame 500 to external forces such as earthquakes and typhoons. In the illustrated example, the architectural turnbuckle 100 is diagonally spanned between the mounting part 50a fixed by welding or the like to the lower part of the column member 51 on the left side of the figure and the mounting part 50a fixed to the upper end part of the column member 51a in the center of the figure. Similarly, the architectural turnbuckle 100 is diagonally spanned between the mounting part 50a fixed by welding or the like to the lower part of the column member 51 on the right side of the figure and the mounting part 50a fixed to the upper end part of the column member 51a in the center of the figure. The two architectural turnbuckles 100 are attached to the frame 500 with an appropriate tension by the worker rotating and adjusting the turnbuckle body 1. In the example shown in FIG. 5A, the horizontal distance between the column members 51, 51a is shortened compared to FIG. 3A, and the resistance of the frame 500 to external forces is further increased by using the same number of architectural turnbuckles 100 as in FIG. 3A.

[0037] FIG. 5B is another example of a frame 600 to which the architectural turnbuckle 100 according to this embodiment is attached. The frame 600 is a building framework formed of three pillar members 51, 51a extending in the vertical direction of the figure when viewed from the front, and two beam members 52 horizontally spanning the upper and lower parts of the pillar members 51, 51a. In this example, the foundation beam 53 as shown in FIG. 5A is not used, and the lower end of the pillar member 51 is fixed to the foundation. As shown in FIG. 5B and other figures, the architectural turnbuckle 100 according to this embodiment is diagonally spanned across the pillar members 51, 51a and the beam member 52 to serve as a diagonal brace, thereby increasing the resistance of the frame 600 to external forces such as earthquakes and typhoons. In the example shown in the figure, the architectural turnbuckle 100 is spanned diagonally between the mounting part 50a fixed by welding or the like to the lower part of the pillar member 51 on the left side of the figure and the mounting part 50a fixed to the upper end of the pillar member 51a in the center of the figure. Similarly, the architectural turnbuckle 100 is diagonally bridged between the mounting part 50a fixed by welding or the like to the lower part of the column member 51 on the right side of the figure and the mounting part 50a fixed to the upper end part of the column member 51a in the center of the figure. In the example shown in Fig. 5B, the horizontal distance between the column members 51, 51a is shortened compared to Fig. 3B, and the resistance of the frame 500 to external forces is further increased by using the same number of architectural turnbuckles 100 as in Fig. 3B.

[0038] As described above, this embodiment is a construction turnbuckle 100 including a turnbuckle body 1 for adjusting the length in the longitudinal direction, and a turnbuckle bolt 10 having a connection portion 2 attached to both longitudinal ends of the turnbuckle body 1 and movable in the longitudinal direction by rotating around the central axis O of the turnbuckle body 1, and each turnbuckle bolt 10 has an attachment portion 20 provided on the opposite side of the turnbuckle body 1 in the longitudinal direction, and the attachment portion 20 has a plurality of plate-like members (base plate portion 21) arranged so as to be approximately parallel to each other, and each of the plate-like members has a hole portion 22 for fixing to the mounting portion 50 on the frame side. By adopting such a configuration, it is possible to make it difficult for bending stress to occur in the attachment portion 20 and the mounting portion 50 on the frame side. Therefore, the load on the high-strength bolt 31 and the fastening nut 32 that fix the attachment portion 20 to the mounting portion 50 on the frame side can be reduced, and the range of selection of the high-strength bolt 31 and the fastening nut 32 can be expanded.

[0039] In this embodiment, the hole 22 is formed at approximately the same position in plan view in each of the plate-like members arranged to be approximately parallel. By adopting such a configuration, the architectural turnbuckle 100 can be attached to the mounting part 50 at any mounting angle with the hole 22 as the center of rotation. Therefore, it is not necessary to change the specifications of the mounting part 50 for each specification of the frame, and a common mounting part 50 can be used for multiple types of frame assemblies with different specifications. In addition, since only one hole 22 is arranged in one base plate part 21 of the mounting part 20, the mounting part 50 (gusset) side to be attached to the base plate part 21 also has only one hole, and the size of the mounting part 50 can be reduced. This configuration can improve the transportation efficiency of the column member 51 and the beam member 52 to which the mounting part 50 is welded and carried to the construction site.

[0040] In this embodiment, the mounting portion 20 of each turnbuckle bolt 10 has two plate-like members, each of which has a substantially rectangular cutout portion 23 at its base end, and the outer circumferential surface of the tip end (rod-like portion 2a) of the rod-like connecting portion 2 is fixed to the edge portion of the cutout portion 23 extending in the longitudinal direction of the architectural turnbuckle 100, and the two plate-like members are arranged at symmetrical positions in the up-down direction with respect to the central axis O. By adopting such a configuration, the round bar-like connecting portion 2 and the flat plate-like mounting portion 20, which are formed separately, can be easily fixed at symmetrical positions in the up-down direction with respect to the central axis O.

[0041] Although the present disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present invention. For example, the functions included in each component can be rearranged so as not to cause logical inconsistency, and multiple components can be combined into one or divided. It should be understood that these are also included in the scope of the present invention.

[0042] For example, in this embodiment, the base plate parts 21 of the mounting part 20 are arranged so that two pieces are approximately parallel to each other at the tip part of the turnbuckle bolt 10, but this is not limited to the embodiment. Three or more base plate parts 21 may be arranged so that they are approximately parallel to each other at the tip part of the turnbuckle bolt 10. In this case, it is preferable to configure so that the center positions of the connection part 2 and the mounting part 20 are not offset in the thickness direction (up and down direction, Z direction) of the mounting part 20. In addition, it is preferable to configure so that the mounting part 20 and the mounting part 50 are not offset in the thickness direction (up and down direction, Z direction) of the mounting part 20 by arranging the mounting part 50 in the space between the base plate parts 21.
