Background Technology

[0002] Generally, when joining modular structures such as pipes, one of the modules is often drilled and fastened using bolts. For example, modules may be placed at the top and bottom and secured internally with bolts. If the modular structure is large, like a container, a worker can enter the interior to fasten the bolts. However, for structures that are narrow and long, such as pipes, it is not easy for a worker to enter the interior or reach out to fasten the bolts.

[0003] In addition, while it is possible to drill the sides of the upper structure and have a worker manually fasten bolts through the drilled holes, it may be difficult to do so if the structure is not easy to drill. Furthermore, drilling the structure may present a problem where the load-bearing capacity of the drilled section is weakened.

[0004] In addition, when joining modular structures, the bolt holes on the upper and lower modules must align. If the bolt holes do not align, an error in the joining position between the upper and lower structures may occur, and a problem may arise where the magnitude of the error increases as the number of structures increases.

Specific details for implementing the invention

[0043] The advantages and features of the embodiments of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments described below but may be implemented in various different forms. These embodiments are provided merely to ensure that the invention is complete and to fully inform those skilled in the art of the scope of the invention, and the invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0044] In describing the embodiments of the present invention, specific descriptions of known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions in the embodiments of the present invention, and these definitions may vary depending on the intentions or practices of the user or operator. Therefore, such definitions should be based on the content throughout this specification.

[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0047] Referring to FIGS. 1 to 9, a non-drilling bolt fastening device (100) equipped with a displacement absorbing cone according to one embodiment of the present invention may include a bolt fastening part (110), a displacement absorbing cone (120), a nut cap (130), a connecting plate (140), etc.

[0049] FIG. 1 is a drawing illustrating a non-drilling bolt fastening device equipped with a displacement absorbing cone according to an embodiment of the present invention, FIG. 2 is a drawing illustrating an upper module, a connecting plate, and a lower module fastened by a non-drilling bolt fastening device equipped with a displacement absorbing cone according to an embodiment of the present invention, FIG. 3 is a drawing illustrating a bolt fastening of a bolt fastening part of a non-drilling bolt fastening device equipped with a displacement absorbing cone according to an embodiment of the present invention, and FIG. 4 is a drawing illustrating a bolt fastening part of a non-drilling bolt fastening device equipped with a displacement absorbing cone according to an embodiment of the present invention.

[0051] Referring to FIGS. 1 to 4, the bolt fastening part (110) can combine the upper module (10) and the lower module (20). The bolt fastening part (110) enters the inner side of the upper module (10), and the upper module (10) and the lower module (20) can be fastened by tightening a bolt (30) that penetrates the fastening hole (B) of the upper module (10) and the fastening hole (B) of the lower module (20) and a nut (40) located on the lower surface of the lower module (20).

[0052] According to one embodiment of the present invention, the bolt fastening part (110) may enter the interior of the upper module (10), and the head of the bolt (30) may be attached to the end of the bolt fastening part (110). Here, there may also be cases where the bolt fastening part (110) enters the interior of the upper module (10) by drilling the side of the upper module (10) to fasten the bolt. However, as the stress in the drilled part of the upper module (10) is weakened, the resistance to external force may also be weakened. In the present invention, when the bolt fastening part (110) enters the interior of the upper module (10) through the upper part of the upper module (10), the upper module (10) and the lower module (20) can be combined without damage to the upper module (10).

[0053] The bolt fastening part (110) may include a fastening rod (111), a fastening wrench (112), a coil (113), an outer cover (114), etc.

[0055] The fastening rod (111) is the body of the bolt fastening part (110), and a fastening wrench (112) is formed at one end, and a coil (113) is wound at the bottom, and an outer cover (114) may be provided on the outer side of the bottom of the fastening rod (111) where the coil (113) and the fastening wrench (112) are formed. In addition, a handle (111a), a battery (111b), a switch (111c), etc. may be formed on the other side of the fastening rod (111).

[0056] The fastening rod (111) may be provided with a conductive material so that magnetism can be formed. When current flows through a wire, a magnetic field can be generated around the wire. By utilizing this property, when current flows through the coil (113), the fastening rod (111) around which the coil (113) is wound develops the properties of an electromagnet, thereby allowing magnetism to be formed in the fastening rod (111). Accordingly, magnetism is also formed in the fastening wrench (112) formed at the end of the fastening rod (111), so that a bolt (30) can be attached to the fastening wrench (112).

[0057] The fastening rod (111) is formed long in the longitudinal direction and can be formed in the shape of a rod. The length of the fastening rod (111) can be formed in various ways depending on the length (or depth) inserted into the interior of the fastening target, but it can be formed to be about 30 cm so that the user can easily adjust the bolt fastening part (110).

[0058] The cross-section of the fastening rod (111) may be formed in a circular or polygonal shape, and the cross-section of the fastening rod (111) may be formed in a circular shape so that the coil (113) can be wound along the outer surface of the fastening rod (111) in close contact with the outer surface. Additionally, a fastening wrench (112) may be formed on one side of the fastening rod (111). As a part of the fastening rod (111), that is, one end portion, is formed as the fastening wrench (112), when current flows through the coil (113) and magnetism is generated in the fastening rod (111), magnetism can also be stably formed in the fastening wrench (112).

[0059] Additionally, a handle (111a), battery (111b), switch (111c), etc. may be formed on the other side of the connecting rod (111).

[0060] A handle (111a) is formed on the upper side of the other end of the fastening rod (111) and may be provided to allow the fastening rod (111) to rotate clockwise or counterclockwise. The handle (111a) may be formed in a bent shape or in a T-shape on the other end of the fastening rod (111). The bolt fastening part (110) may enter the inside of the upper module (10) to combine the upper module (10) and the lower module (20). Here, the upper module (10) may be formed with a long length (or a deep depth), so it may not be easy for the user to directly fasten the bolt (30). The handle (111a) may be provided to be located on the other end of the bolt fastening part (110), that is, on the user side. Accordingly, the user can easily rotate the handle (111a) by gripping it, and by rotating the handle (111a) so that the fastening rod (111) also rotates, the bolt (30) can be stably fastened or unfastened.

[0061] The battery (111b) can supply power to allow current to flow to the coil (113). Here, since one side of the fastening rod (111) enters into the upper module (10) and performs the function of fastening the bolt (30), the battery (111b) may be provided on the other side of the fastening rod (111) so that the battery (111b) does not interfere with the bolt fastening operation.

[0062] A switch (111c) is provided on the other side of the fastening rod (111) and can control the supply of current flowing to the coil (113) and the strength of the current. The switch (111c) can control the supply of current to the coil (113) so that current flows to the coil (113) and magnetism can be formed on the fastening rod (111) (especially the fastening wrench (112)). That is, when the switch (111c) is turned on, current flows to the coil (113) and magnetism can be formed on the fastening rod (111), and when the switch is turned off, the supply of current to the coil (113) is stopped and magnetism on the fastening rod (111) can be removed.

[0063] Additionally, the switch (111c) can adjust the magnitude (or amount) of the current flowing through the coil (113). The strength of the magnetic field formed by the current flowing through the coil (113) may be proportional to the strength of the current. Accordingly, by adjusting the switch (111c), if the magnitude or amount of the current flowing through the coil (113) increases, the attachment force of the fastening wrench (112) to the bolt (30) may increase. Alternatively, if the magnitude or amount of the current flowing through the coil (113) decreases, the attachment force of the fastening wrench (112) to the bolt (30) may also decrease.

[0065] A fastening wrench (112) is formed at the lower end of a fastening rod (111) and can be inserted into a bolt (30) to fasten the bolt (30). Here, the fastening wrench (112) may be formed integrally with the fastening rod (111), with the lower end of the fastening rod (111) being formed in the shape of a wrench. In particular, the fastening wrench (112) according to one embodiment of the present invention may be formed as an Allen wrench. An Allen wrench is a hexagonal wrench in which the head inserted into the bolt is formed in a hexagonal shape. By forming the fastening wrench (112) such that its outer diameter corresponds to the inner diameter of the bolt (30), the fastening wrench (112) is inserted into the bolt (30), and as the fastening wrench (112) rotates, the bolt (30) can be tightened or loosened.

[0066] Additionally, the fastening wrench (112) may have magnetism formed so that the bolt (30) can be attached to the fastening wrench (112). That is, when current flows through the coil (113), magnetism is formed in the fastening rod (111) around which the coil (113) is wound, and thus magnetism can also be formed in the fastening wrench (112) formed at the lower end of the fastening rod (111). By the magnetism of the fastening wrench (112), the bolt (30) can be attached to the fastening wrench (112), thereby making it easier to perform the bolt (30) fastening operation. The module, pipe, etc., to which the bolt fastening part (110) can be used may be formed with a narrow width or a deep depth, making it difficult to move the bolt (30) to the fastening position, and if the bolt (30) deviates from the fastening position, it is not easy to re-insert the bolt (30) into the fastening position. Here, when a bolt (30) is attached to the fastening wrench (112), the bolt fastening part (110) is moved to the bolt insertion position, allowing the bolt (30) to be stably inserted into the fastening hole (B). Additionally, even if the bolt (30) detaches from the fastening hole (B) during the fastening process, the bolt (30) can be reattached to the fastening wrench (112) by the magnetism of the fastening wrench (112) to move and insert the bolt (30) back into the fastening hole (B).

[0067] The fastening wrench (112) can be manufactured in the shape of an Allen wrench by cutting off the end portion of the fastening rod (111). When the fastening wrench (112) is inserted into the bolt (30), the inner surface of the bolt (30) can come into contact with the outer surface of the fastening wrench (112). Additionally, the outer surface of the bolt (30) can come into contact with the inner surface of the outer cover (114). Accordingly, when the fastening wrench (112) rotates, the bolt (30) can receive rotational force from the inner side via the fastening wrench (112) and from the outer side via the outer cover (114), so it can efficiently rotate in the fastening or unfastening direction.

[0069] The coil (113) can be wound around the connecting rod (111) along the outer surface of the connecting rod (111). When current flows through the coil (113), a magnetic field is formed around the coil (113), and the direction of the magnetic field can be determined according to Ampere's law. Additionally, the strength of the formed magnetic field may vary depending on the strength of the current, the number of times it is wound per unit length, etc.

[0070] According to one embodiment of the present invention, a coil (113) can be wound on the lower part of a fastening rod (111). When current flows through the wound coil (113), a magnetic field is formed around the coil (113), and the fastening rod (111) on which the coil (113) is wound can be magnetized. Accordingly, a fastening wrench (112) formed at one end of the fastening rod (111) can also be magnetized, and a bolt (30) can be attached to the fastening wrench (112).

[0071] Additionally, the coil (113) may be connected to a switch (111c), a battery (111b), etc. Power is supplied by the battery (111b), and current may flow through the coil (113). Additionally, the current may be controlled to flow through the coil (113) or to stop flowing by the switch (111c), and the magnitude and amount of the current flowing through the coil (113) may be controlled by the switch (111c). Additionally, the coil (113) may be inserted into the inner side of the fastening rod (111) and connected to the switch (111c), etc., or connected to the switch (111c) along the longitudinal direction on the outer side of the fastening rod (111). .

[0073] The outer cover (114) is provided on the outer side of the fastening rod (111) in the longitudinal direction of the fastening rod (111), and a coil (113) and a fastening wrench (112) may be arranged inside. The outer cover (114) may be formed on the lower outer side of the fastening rod (111) in a shape that covers the coil (113) and the fastening wrench (112) so as to protect the coil (113) and the fastening wrench (112) formed on the fastening rod (111). Here, if the coil (113) wound on the fastening rod (111) is damaged or destroyed by external stimuli, it may be difficult to stably form magnetism on the fastening rod (111). To prevent this, the outer cover (114) may be provided to cover the entire coil (113) wound on the fastening rod (111). Additionally, the outer cover (114) may be extended to a predetermined length in a portion of the fastening rod (111) where the coil (113), fastening wrench (112), etc. are not formed. One end of the outer cover (114) may be formed to be parallel in the width direction with the end of the fastening wrench (112), or the end of the fastening wrench (112) may be located inside the fastening rod (111) rather than the inner end of the outer cover (114).

[0074] Additionally, the outer cover (114) may be formed with one end open so that a bolt (30) can enter through one end. A bolt (30) can be inserted into the inner side of the outer cover (114) through the open one end of the outer cover (114), and a fastening wrench (112) can be inserted into the bolt (30) from the inner side of the outer cover (114). As the other end of the outer cover (114) is coupled to the fastening rod (111), the outer cover (114) can be positioned in a fixed state on the outer side of the fastening rod (111).

[0075] An outer cover (114) according to one embodiment of the present invention may be formed in a tubular (i.e., pipe) shape such as a polygon or a circle. In particular, the inner surface of the lower part of the outer cover (114) may be formed to correspond to the head shape of the bolt (30). Here, the inner surface of the lower part of the outer cover (114) may refer to a cross-section in the width direction on the inner side of the lower part of the outer cover (114). For example, if the bolt (30) is formed as an Allen bolt (hexagonal bolt), the cross-section of the lower inner surface of the outer cover (114) in the width direction may be formed as a hexagon, and if the head of the bolt (30) is formed as a square, the inner surface of the lower part of the outer cover (114) may be formed as a square. In addition, the inner surface of the outer cover (114) formed to correspond to the head shape of the bolt (30) may be formed with a length that is longer than the thickness of the head of the bolt (30) by a predetermined length. Accordingly, when the bolt (30) is inserted into the inner side of the outer cover (114) through the lower part of the outer cover (114), the entire head of the bolt (30) can come into contact with the inner surface of the outer cover (114).

[0076] As described above, when the inner surface of the lower part of the outer cover (114) is formed to correspond to the head shape of the bolt (30), the inner surface of the outer cover (114) and the head of the bolt (30) can be in close contact. Accordingly, when the fastening rod (111) rotates, the bolt (30) can receive rotational force from the outside through the outer cover (114) that is in close contact with the outer surface of the bolt (30). In addition, as previously explained, a fastening wrench (112) is inserted into the inner side of the bolt (30), so that the rotational force of the fastening wrench (112) can act on the bolt (30) from the inner side of the bolt (30). In this way, the bolt (30) receives rotational force from the inner side through the fastening wrench (112) and from the outer side through the outer cover (114), thereby allowing the fastening operation of the bolt (30) to be performed efficiently.

[0078] FIG. 5 is a drawing illustrating the insertion of a displacement absorbing cone into a module of a non-drilling bolt fastening device equipped with a displacement absorbing cone according to one embodiment of the present invention, and FIG. 6 is a drawing illustrating a displacement absorbing cone of a non-drilling bolt fastening device equipped with a displacement absorbing cone according to one embodiment of the present invention.

[0079] Referring to FIGS. 5 and 6, the displacement absorbing cone (120) can align the upper module (10) and the lower module (20) by penetrating the center hole (C1) of the upper module (10) and the center hole (C3) of the lower module (20). When modules located at the upper and lower parts are combined, the connection position between the upper and lower modules, in particular, the fastening position of the bolt connecting the upper and lower modules, must match. This is to prevent the error in the connection position from increasing as multiple modules are stacked if an error occurs in the connection position between the upper and lower modules. That is, the displacement absorbing cone (120) can align the upper module (10) and the lower module (20) so that the connection position between the upper module (10) and the lower module (20) matches. In addition, it can absorb positional deformation between the upper module (10) and the lower module (20) that may occur when there is a mismatch in the combined position of the upper module (10) and the lower module (20) (i.e., it can absorb errors in positional displacement).

[0080] When the upper module (10) and the lower module (20) are combined, a center hole (C1, C3) may be formed at the center of the fastening position of the upper module (10) and the center of the fastening position of the lower module (20), respectively. The center hole (C) is a hole formed to penetrate the center of the combined part of the upper module (10) and the lower module (20). The diameter of the center hole (C) may be formed to correspond to the diameter of the displacement absorption cone (120). Additionally, the center hole (C1) of the upper module (10) and the center hole (C3) of the lower module (20) may have the same diameter, or the diameter of the center hole (C1) of the upper module (10) may be larger. This will be explained later.

[0081] Additionally, a fastening hole (B) may be formed at the joint location of the upper module (10) and the lower module (20) so that a bolt (30) can be joined. Multiple fastening holes (B) may be formed. By the bolt (30) passing through the fastening hole (B) of the upper module (10) and the fastening hole (B) of the lower module (20), the head of the bolt (30) may be positioned on the upper part of the upper module (10), and the penetrating part of the bolt (30) and the nut (40) may be positioned on the lower part of the lower module (20).

[0082] In one embodiment of the present invention, the displacement absorbing cone (120) may have a head portion (121) formed at the upper end, a body portion (122) formed at the middle or lower end, etc.

[0083] Referring to FIG. 6, the head portion (121) may be positioned to protrude upward from the upper module (10) and have a tip portion formed therein. That is, the head portion (121) may be positioned above the central hole (C1) of the upper module (10). Additionally, the head portion (121) may be formed in the shape of a cone or a polygonal horn. The head portion (121) may be formed in a shape where the height decreases from the center to the edge so that a tip portion can be formed in the head portion (121). Accordingly, the head portion (121) may have a shape of an inclined plane as it goes from the center to the edge in the height direction (or length direction). As described above, by forming a tip portion in the center of the head portion (121), when checking the internal connection position of the upper module (10) from above the upper module (10), the center of the connection position can be easily identified by checking the tip portion. In this way, when the center of the connection position is confirmed, the location of the fastening hole of the bolt (30) located at a predetermined distance from the center of the connection position can also be easily confirmed. Additionally, since a tip is formed in the center of the head portion (121), when one end of the bolt fastening portion (110) enters the upper module (10) and comes into contact with the displacement absorption cone (120), it slides due to the inclined surface of the head portion (121) of the displacement absorption cone (120), so the user can confirm by touch or the like that the entry direction of the bolt fastening portion (110) is not facing the fastening hole (B).

[0084] The body portion (122) of the displacement absorbing cone (120) is formed to extend downward from the head portion (121) and may be located inside the center hole (C1) of the upper module (10) and the center hole (C3) of the lower module (20). The body portion (122) may be positioned to penetrate the upper module (10) and the lower module (20). Additionally, if a connecting plate (140) is provided between the upper module (10) and the lower module (20), the body portion (122) may be positioned to penetrate the entire upper module (10), the connecting plate (140), and the lower module (20).

[0085] A body part (122) according to one embodiment of the present invention is positioned to penetrate the upper module (10), lower module (20), etc., thereby aligning the upper module (10), lower module (20), etc., so that the upper module (10), lower module (20), etc., can be positioned at a combined position. Here, when the body part (122) is inserted into the center holes (C1, C3) of the upper module (10), lower module (20), etc., a gap may occur between the outer surface of the body part (122) and the inner surface of the center holes (C1, C3). The diameter of the body part (122) may be formed so that such a gap can be formed within a predetermined allowable range. That is, the diameter of the body part (122) may be formed to correspond to the diameter of the center holes (C1, C3).

[0086] Referring to FIG. 6(b), the body portion (122) may be formed such that the displacement absorbing cone (120) is inclined inward from the top to the bottom. That is, the diameter of the body portion (122) may be reduced from the top of the body portion (122) where the head portion (121) and the body portion (122) come into contact to the bottom (or bottom surface) of the body portion (122). As previously explained, the diameter of the body portion (122) may be formed to correspond to the diameter of the central hole (C). Accordingly, the diameter of the central hole (C1) of the upper module (10) may be formed to be larger than the diameter of the central hole (C3) of the lower module (20). Additionally, when a connecting plate (140) is provided between the upper module (10) and the lower module (20), the diameter of the central hole (C1) of the upper module (10) can be formed to be the largest, and the diameters of the central holes (C2, C3) can be formed in the order of the connecting plate (140) and the lower module (20).

[0087] In this way, when the upper module (10), connecting plate (140), and lower module (20) are formed, the displacement absorbing cone (120) can be inserted by fitting into the respective center holes (C1, C2, C3) of the upper module (10), connecting plate (140), and lower module (20). Additionally, since the diameter of the center hole (C3) of the lower module (20) is formed to be the smallest, when the displacement absorbing cone (120) is inserted into the center hole (C), the displacement absorbing cone (120) can be prevented from coming out through the lower part of the center hole (C3) of the lower module (20).

[0088] Additionally, referring to FIG. 6(c), the body portion (122) may have a vertical surface (122a) formed such that the diameter of the body portion (122) is constant from the top to the bottom. In this case, the diameter of the bottom of the head portion (121) may be formed larger than the diameter of the top of the body portion (122). That is, a step may be formed between the bottom of the head portion (121) and the top of the body portion (122). As previously described, the diameter of the body portion (122) is formed to correspond to the diameter of the center hole (C), so that the diameter of the center hole (C1) of the upper module (10), the diameter of the center hole (C2) of the connecting plate (140), and the diameter of the center hole (C3) of the lower module (20) may be formed to be constant (or equal). When a displacement absorbing cone (120) is inserted into such an upper module (10), the displacement absorbing cone (120) may be displaced downward from the lower module (20). However, since a step is formed between the lower end of the head part (121) and the upper end of the body part (122), the lower end of the head part (121) catches on the edge side of the center hole (C1) of the upper module (10), thereby preventing the displacement absorbing cone (120) from displaced downward through the center hole (C3) of the lower module (20).

[0089] In addition, a body part (122) according to one embodiment of the present invention may have a screw thread, that is, a male screw thread (122b), formed on its lower portion. The male screw thread (122b) of the body part (122) may be coupled to a female screw thread (20a) formed in the lower module (20) through screw coupling. That is, when the body part (122) is inserted into the lower module (20), etc., the body part (122) is fixed by screw coupling to the lower module (20), thereby allowing the displacement absorbing cone (120) to be stably positioned in the central hole (C3) of the lower module (20), etc.

[0090] As described above, the displacement absorbing cone (120) can align the upper module (10), lower module (20), etc., and combine the upper module (10), lower module (20), etc.

[0092] FIG. 7 is a drawing illustrating the alignment of displacement absorption cone modules of a non-drilling bolt fastening device equipped with a displacement absorption cone according to one embodiment of the present invention, and FIG. 8 is a drawing illustrating the alignment of displacement absorption cone modules of a non-drilling bolt fastening device equipped with a displacement absorption cone according to one embodiment of the present invention.

[0094] The method of aligning modules, etc., using a displacement absorbing cone (120) in which the body part (122) is formed at an angle and combining the upper module (10) and the lower module (20) is as follows.

[0095] Referring to FIG. 7 (a), (b1) and (c1), in a first embodiment of the present invention, an upper module (10) and a lower module (20) may be provided such that the diameter of the central hole (C1) of the upper module (10) is larger than the diameter of the central hole (C3) of the lower module (20). The upper module (10) and the lower module (20) may be arranged (or stacked) in an upper and lower position to combine them. Next, a displacement absorbing cone (120) is inserted into the central hole (C1) of the stacked upper module (10), and the displacement absorbing cone (120) is rotated so that the male screw thread (122b) of the body part (122) is coupled to the female screw thread (20a) of the lower module (20). Accordingly, the upper module (10) and the lower module (20) may be aligned. Next, the upper module (10) and the lower module (20) can be joined by inserting a bolt (30) into the fastening hole (B) of the upper module (10) and the fastening hole (B) of the lower module (20) and tightening the bolt (30) with the bolt fastening part (110). Additionally, if a connecting plate (140) is provided, the arrangement process of the modules may include a process of stacking and arranging them in the order of the lower module (20), the connecting plate (140), and the upper module (10).

[0096] Additionally, referring to FIG. 7 (a), (b1) and (d1), in a second embodiment of the present invention, first, a lower module (20) is placed and a displacement absorbing cone (120) is inserted into the center hole (C3) of the lower module (20), and the displacement absorbing cone (120) is rotated so that the body part (122) of the displacement absorbing cone (120) can be fixed to the lower module (20) by screw connection. Next, the upper module (10) is placed on the displacement absorbing cone (120) so that the displacement absorbing cone (120) penetrates the center hole (C1) of the upper module (10), thereby aligning the upper module (10) and the lower module (20). Next, as previously described, the process of connecting the bolt (30) by the bolt fastening part (110) can be performed. Additionally, when a connecting plate (140) is provided, the process of arranging the modules and inserting the displacement absorbing cone (120) may include a process in which the lower module (20) and the connecting plate (140) are stacked, the displacement absorbing cone (120) is inserted into the center hole (C2) of the lower module (20) and the connecting plate (140), and the upper module (10) is seated on the displacement absorbing cone (120).

[0097] However, with reference to (a), (b2), (c2) and (d2) of FIG. 7, if the diameters of the center hole (C1) of the upper module (10) and the center hole (C3) of the lower module (20) are formed to be the same, it may not be easy to align the upper module (10) and the lower module (20) with the displacement absorbing cone (20) of this shape.

[0099] In addition, the method of aligning modules, etc., using a displacement absorbing cone (120) in which a step is formed between the body part (122) and the head part (121) and the diameter of the body part (122) is formed equally, and combining the upper module (10) and the lower module (20) is as follows.

[0100] Referring to FIG. 8 (a), (b1) and (c1), in a third embodiment of the present invention, an upper module (10) and a lower module (20) may be provided such that the diameter of the central hole (C1) of the upper module (10) is larger than the diameter of the central hole (C3) of the lower module (20). The upper module (10) and the lower module (20) may be arranged (or stacked) in an upper and lower position to combine them. Next, a displacement absorbing cone (120) is inserted into the central hole (C1) of the stacked upper module (10), and the displacement absorbing cone (120) is rotated so that the male screw thread (122b) of the body part (122) is coupled to the female screw thread (20a) of the lower module (20). Accordingly, the upper module (10) and the lower module (20) may be aligned. Next, the upper module (10) and the lower module (20) can be joined by inserting a bolt (30) into the fastening hole (B) of the upper module (10) and the fastening hole (B) of the lower module (20) and tightening the bolt (30) with the bolt fastening part (110). Additionally, if a connecting plate (140) is provided, the arrangement process of the modules may include a process of stacking and arranging them in the order of the lower module (20), the connecting plate (140), and the upper module (10).

[0101] Additionally, referring to FIG. 8 (a), (b2) and (c2), in a fourth embodiment of the present invention, an upper module (10) and a lower module (20) may be provided such that the diameter of the central hole (C1) of the upper module (10) is formed to be the same as the diameter of the central hole (C3) of the lower module (20). In the case of the fourth embodiment, similar to the third embodiment, the upper module (10), the lower module (20), etc., may all be stacked (or arranged), and the displacement absorbing cone (120) may be inserted to align the upper module (10) and the lower module (20).

[0102] However, referring to FIG. 8 (a), (d2) and (d2), the diameter of the center hole (C1) of the upper module (10) is formed to be smaller than the diameter of the bottom of the body part (122), so it may not be easy or impossible for the head part (121) of the displacement absorbing cone (120) to pass through the center hole (C1) of the upper module (10). Accordingly, after the displacement absorbing cone (120) is coupled to and fixed to the lower module (20), the process of the displacement absorbing cone (120) penetrating the upper module (10) while the upper module (10) is seated on the displacement absorbing cone (120) may be difficult to perform.

[0104] FIG. 9 is a drawing illustrating a nut cap of a non-drilling bolt fastening device equipped with a displacement absorbing cone according to one embodiment of the present invention.

[0105] Referring to FIG. 9, the nut cap (130) is a member coupled to the nut (40) so that the nut (40) is fixedly positioned on the lower surface of the lower module (20), and may include a cap cover (131), a nut guide (132), etc.

[0106] When bolt fastening is performed by the bolt fastening part (110), the nut (40) is positioned at the bottom of the lower module (20), and as the bolt (30) rotates while the nut (40) is fixed, the bolt (30) and the nut (40) can be joined. The nut cap (130) can support the nut (40) so that the nut (40) is fixed to the bottom of the lower module (20).

[0108] The cap cover (131) is attached to the lower surface of the lower module (20) and can accommodate and secure a nut guide into which a nut (40) is inserted. The cap cover (131) is formed in a cap shape, and a fixing surface (131b) may be formed radially outward from the upper part of the cap cover (131). Additionally, a fixing hole (131a) may be formed on the side of the cap cover (131) so that a fixing pin (132b) of the nut guide (132) can be inserted, and the central part may be formed open so that a bolt (30) can pass through.

[0109] According to one embodiment of the present invention, the upper surface of the cap cover (131) is formed as a fixed surface (131b), and the cap cover (131) can be fixed to the lower surface of the lower module (20) by attaching the fixed surface (131b) to the lower surface of the lower module (20). The fixed surface (131b) can be fixed to the surface of the lower module (20) by welding or the like, and the fixing method is not limited to welding, and bolting or rivets may be used.

[0110] The fixing holes (131a) can be formed to correspond to the number of fixing pins (132b), and one fixing hole (131a) can be formed in the shape of an "L", while the other fixing hole (131a) can be formed in the shape of an "I". Through this structure, the nut guide (132) can be easily mounted on the cap cover (131) and can be prevented from coming off.

[0112] The nut guide (132) is formed in a ring shape, and a fixing part (132a) is formed on the hollow inner side, and a plurality of fixing pins (132b) may be provided on the outer side. The fixing part (132a) may be formed to correspond to the shape of the nut (40) so that the nut (40) is fixed. Since the outer side of the nut (40) according to one embodiment of the present invention is formed in a hexagonal shape, the fixing part (132a) may also be formed in a hexagonal shape. As the nut (40) is inserted into the fixing part (132a) and the lower part of the inserted nut (40) rests on the bottom surface of the cap cover (131), the inserted nut (40) may be prevented from falling out through the lower part of the fixing part (132a). When the bolt (30) rotates by the bolt fastening part (110), the nut (40) into which the bolt (30) is inserted may rotate together with the rotational force of the bolt (30). However, if the bolt (30) and the nut (40) rotate together in this manner, the bolt (30) may not be fastened to the nut (40) and may spin freely. When the bolt (30) rotates while the nut (40) is inserted into the fixing part (132a), the bolt (30) rotates, but the rotation of the nut (40) is prevented by the fixing part (132a). Therefore, the nut (40) can be tightened upward by the rotation of the bolt (30), so the bolt (30) and the nut (40) can be stably fastened.

[0113] The nut guide (132) is provided with a plurality of fixing pins (132b) that protrude outward from the outer surface, and the fixing pins (132b) are inserted into fixing holes (131b) formed in the cap cover (131), thereby allowing the nut guide (132) to be fixed to the cap cover (131). That is, when the fixing pins (132b) are inserted into the fixing holes (131a), movement can be prevented against horizontal forces (e.g., rotational force) acting on the nut guide (132). Accordingly, even if the bolt fastening part (110) rotates the bolt (30) and rotational force is transmitted to the nut guide (132) through the nut (40), the nut guide (132) can remain fixed in position without rotating.

[0115] A connecting plate (140) can be placed between the upper module (10) and the lower module (20) to adjust the length between the upper module (10) and the lower module (20) according to the length of the displacement absorption cone (120).

[0116] As previously exemplified, the displacement absorbing cone (120) can be formed in various shapes depending on the shape of the body part (122), and the upper module (10) and lower module (20) can be formed with various thicknesses, diameters of the central hole (C), etc. Here, if the length of the displacement absorbing cone (120) is longer than the allowable range than the thickness of the stacked upper module (10) and lower module (20), it is difficult for the upper module (10) and lower module (20) to be stably aligned even if the displacement absorbing cone (120) is inserted into the upper module (10) and lower module (20). In addition, if the diameter of the upper module (10) is formed to be larger than the diameter of the lower module (20) within the allowable range, the displacement absorbing cone (120) inserted inside the central hole (C1) of the upper module (10) may be positioned randomly, making it difficult for the upper module (10) and lower module (20) to be stably aligned.

[0117] A connecting plate (140) according to one embodiment of the present invention is disposed between an upper module (10) and a lower module (20), and can be formed such that the sum of the thicknesses of the upper module (10), the lower module (20), and the connecting plate (140) corresponds to the length of the displacement absorbing cone (120). Additionally, the diameter of the central hole (C2) of the connecting plate (140) can be formed to be smaller than the diameter of the central hole (C1) of the upper module (10) and larger than the diameter of the central hole (C3) of the lower module (20). As such, the connecting plate (140) is positioned between the upper module (10) and the lower module (20), the displacement absorbing cone (120) penetrates the center hole (C1) of the upper module (10), the center hole (C2) of the connecting plate (140), and the center hole (C3) of the lower module (20), thereby allowing the upper module (10) and the lower module (20) to be stably aligned.

[0119] Although various embodiments of the present invention have been presented and described in the above description, the present invention is not necessarily limited thereto, and those skilled in the art will readily understand that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
