Description

Technical Field

[0001] The present invention relates to an anchor including an epoxy resin bag, and more particularly, to an anchor including a breakable epoxy resin bag. Background Art

[0002] In recent years, as concrete performance has improved, the load used has increased, and cracks have sometimes appeared in concrete structures. Cracks reduce the performance of concrete and can cause fatal defects when anchors are installed later. In particular, stress is concentrated in the part where the anchors are installed later, and when external loads act, cracks often penetrate the anchors. The anchors installed later, which are fixed in the concrete, can cause the concrete to split and break.

[0003] In order to prevent cracks caused by the anchor and improve the bonding strength during anchor construction, usually, after drilling holes in the concrete structure with a drill, adhesive is injected into the drilled bonding holes to fix the anchor with the adhesive. However, such construction requires the step of injecting adhesive, which is troublesome and takes a long time. In most cases, multiple anchors are constructed at one time, so when the adhesive is injected into the bonding holes to be inserted into the anchors in advance, the adhesive often solidifies before the anchors are inserted.

[0004] In order to prevent this, there is an attempt to place the adhesive inside the anchor. Korean Patent Publication No. 10-1999-0015339 relates to an anchor bolt, in which there is a space inside the anchor for a capsule filled with an adhesive to enter. The capsule filled with the adhesive is inserted, and other striking means are used to strike the capsule to break it. This requires inserting the adhesive capsule into the anchor and breaking it, which increases the number of working steps, and thus has the disadvantages of being troublesome and time-consuming.

[0005] In addition, Korean Registered Patent Gazette No. 10-0552101 relates to a tunnel construction method and an anchor bolt used therefor, and discloses a concept of inserting an adhesive capsule 5 into a hole 2a and punching the anchor bolt 60 before inserting the anchor bolt 60. This also includes a step of inserting the adhesive capsule 5 into the hole 2a in addition to the anchor bolt insertion step.

[0032] Hereinafter, the anchor rod according to the present invention will be described in detail with reference to the accompanying drawings.

[0033] 1. Description of anchor structure

[0034] Reference Figures 1 to 3 , the anchor rod according to the first embodiment of the present invention is described.

[0035] like Figure 1 As shown, the anchor rod 100 according to the first embodiment of the present invention comprises: a threaded portion 110 , a main body 120 , an expansion sleeve 130 , a pin 140 and a first epoxy resin bag 150 .

[0036] The threaded portion 110 is a hollow cylindrical shape and includes external threads on its outer circumference. A nut 111 and a washer 112 described later can be threadedly fastened on the outer circumference of the threaded portion 110. A pin 140 described later can be inserted into the hollow portion of the threaded portion 110.

[0037] The nut 111 can be fastened to the external thread of the threaded portion 110. The shape of the nut 111 can be selected from but not limited to a hexagon, an octagon or a quadrangle. By rotating the nut 111 toward the coupling hole 200, the nut 111 can be fixed to the structure to be fixed.

[0038] The washer 112 is annular and can be located between the nut 111 and the structure 250 to be fixed. The washer 112 is placed below the nut 111 to disperse the pressure and protect the surface of the structure 250.

[0039] The main body 120 is a hollow cylindrical shape and can be located at the lower side of the threaded portion 110. A pin 140 described later can be inserted into the hollow of the main body 120. When the pin 140 is not struck, the tip of the pin 140 can be located in the main body 120 because the hollow of the expansion sleeve 130 is narrow. When the main body 120 is inserted into the coupling hole 200, it can be located in the coupling hole 200. When the first epoxy resin bag 150 described later is broken, the main body 120 can be surrounded by the epoxy resin 150' flowing out of the first epoxy resin bag 150.

[0040] The expansion sleeve 130 is located at the lower side of the main body 120, and the diameter of the hollow part thereof gradually decreases as it approaches the end. The expansion sleeve 130 may be configured to be thicker as it approaches the end, but not exceeding the diameter of the main body. The pin 140 may be inserted into the hollow part of the expansion sleeve 130, but the hollow part into which the pin 140 is inserted becomes narrower as it approaches the end. When the pin 140 is not struck, the pin 140 may not be located in the expansion sleeve 130 due to the narrow hollow part of the expansion sleeve 130.

[0041] The expansion sleeve 130 may include at least one slit 131. The slit 131 may be an elongated groove formed in the length direction of the expansion sleeve 130. When the pin 140 is struck, the slit 131 of the expansion sleeve 130 is opened by the force of the strike, and the pin 140 may pass through the hollow of the expansion sleeve 130. The expansion sleeve 130 is pushed into the inner side of the coupling hole 200 and may be firmly fixed in the coupling hole 200 by a hook force and a friction force. The expansion sleeve 130 may include folds to increase the friction force with the coupling hole 200. The first epoxy resin bag 150 described later may be broken by the force of the expansion sleeve 130 being unfolded by the pin 140.

[0042] When the pin 140 is not struck, the pin 140 may be located in the hollow of the threaded portion 110 and the main body 120. One side of the pin 140 may include a protrusion to the outside of the threaded portion 110. When the protruding pin 140 is struck with a striking tool, it may be inserted into the hollow of the threaded portion 110, the main body 120, and the expansion sleeve 130. The diameter of the pin 140 may be less than or equal to the hollow diameter of the threaded portion 110 and the main body 120. The first epoxy resin bag 150 may be located at the lower end of the pin 140. The pin 140 may include one side that can be struck by the striking tool, and the other side that is pointed so that the first epoxy resin bag 150 can be broken. When the anchor 100 is inserted into the coupling hole 200 and the pin 140 is struck with the striking tool, the pin 140 is inserted into the hollow of the expansion sleeve 130 and the first epoxy resin bag 150 can be broken.

[0043] The first epoxy resin bag 150 contains epoxy resin 150', covers the outer peripheral surface of the expansion sleeve 130, and can be formed of a crushable material. When the pin 140 is struck by a striking tool, the pin 140 can penetrate the first epoxy resin bag 150 and be crushed. In addition, the first epoxy resin bag 150 can be crushed by the expansion sleeve 130.

[0044] The first epoxy resin bag 150 and the second epoxy resin bag 151 and the third epoxy resin bag 152 described later may be formed of a breakable plastic film or the like, and may be implemented using a 3D printer. Fragments 150 may be produced by the breakage of the first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152. The first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152 will not be broken under lighter impacts such as transfer. In order to effectively break the first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152, a cutout 155 may be included on the first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152. When the first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152 are broken, the first epoxy resin bag 150, the second epoxy resin bag 151 and the third epoxy resin bag 152 are broken. When the three epoxy resin bags 152 are broken, they can be broken along the cutouts 155. Through the cutouts 155 of the first epoxy resin bag 150, the second epoxy resin bag 151, and the third epoxy resin bag 152, the first epoxy resin bag 150, the second epoxy resin bag 151, and the third epoxy resin bag 152 are not only broken on the side that is impacted or stressed, but can also be broken evenly along the cutouts 155. Therefore, the epoxy resin 150' filled in the first epoxy resin bag 150, the second epoxy resin bag 151, and the third epoxy resin bag 152 can flow out at even positions without biasing to any one side when broken.

[0045] The epoxy resin 150' may be filled in the first epoxy resin bag 150, the second epoxy resin bag 151, and the third epoxy resin bag 152. The epoxy resin 150' flows out from the broken first epoxy resin bag 150, the second epoxy resin bag 151, and the third epoxy resin bag 152, and is buried between the anchor rod 100 and the coupling hole 200, so that they can be integrated. In particular, the epoxy resin 150' can firmly fix the main body 120, the expansion sleeve 130, and the coupling hole 200. The epoxy resin 150' can be cured after a certain period of time.

[0046] The coupling hole 200 is generated by drilling a hole at a position where the anchor rod is to be coupled. During anchor rod construction, the drilling depth is generally greater than the length of the anchor rod and the drilling width is greater than the width of the anchor rod. Therefore, the anchor rod 100 including the first epoxy resin bag 150 can be inserted.

[0047] Below, refer to Figures 4 to 7 The anchor rods according to the second to fifth embodiments of the present invention will be described in detail.

[0048] First, it should be noted that this is no longer described with Figures 1 to 3 The repeated parts of the content described.

[0049] like Figure 4As shown, in the anchor rod of the second embodiment, the second epoxy resin bag 151 may be located at the lower side of the washer 112 and surround the outer side of the main body 120. An anti-push component 160 may also be included at the boundary between the main body 120 and the expansion sleeve 130. The anti-push component 160 is located at the lower side of the second epoxy resin bag 151, and when the nut 111 rotates, the second epoxy resin bag 151 can be prevented from being pushed toward the expansion sleeve 130. In the process of rotating the nut 111 toward the washer 112 to fix it, the pressure is transmitted to the second epoxy resin bag 151 and it can be broken.

[0050] like Figure 5 As shown, the anchor rod of the third embodiment can include the features of the anchor rod of the first embodiment and the anchor rod of the second embodiment. By including the first epoxy resin bag 150 and the second epoxy resin bag 151 at the same time, a stronger bonding force can be provided.

[0051] The first epoxy resin bag 150 may be broken by the hitting of the pin 140 or may be broken by the expansion of the expansion sleeve 130 , and the second epoxy resin bag 151 may be broken by the pressure when the nut 111 is rotated.

[0052] When the anchor rod of the third embodiment can play the role of the anti-push component 160 to prevent the second epoxy resin bag 151 from being pushed and moved by the first epoxy resin bag 150 , the anti-push component 160 can be omitted.

[0053] As described above, the first epoxy resin bag 150 and the second epoxy resin bag 151 are provided with cutouts 155 at regular intervals, so that the epoxy resin 150' can flow out evenly when broken. The epoxy resin 150' flows out at an even position without biasing to one side through the cutouts 155', so that the anchor rod and the coupling hole 200 can be integrated.

[0054] The anchor rod can be effectively utilized as the first embodiment including only the first epoxy resin bag 150 , and can also be effectively utilized as the second embodiment including only the second epoxy resin bag 151 .

[0055] In addition, the anchor rod can also be effectively used as a third embodiment that combines the first embodiment and the second embodiment.

[0056] like Figure 6 As shown, the anchor bolt of the fourth embodiment is a wedge-shaped anchor bolt, and by rotating the nut 111, as the expansion head 170 connected to the threaded portion 110 approaches the nut 111 side, the expansion sleeve 130 is expanded, thereby breaking the third epoxy resin bag 152.

[0057] In the anchor rod of the fourth embodiment, the third epoxy resin bag 152 may be arranged to partially surround the expansion head 170. As the diameter of the expansion head 170 gradually widens, the expansion sleeve 130 may be deployed along the expansion head 170. The expansion sleeve 130 deployed through the expansion head 170 may break the third epoxy resin bag 152 surrounding one side of the expansion head 170.

[0058] As described above, the third epoxy resin bag 152 is provided with cutouts 155 at regular intervals so that the epoxy resin 150' can flow out evenly when broken. The epoxy resin 150' flows out at even positions through the cutouts 155', so that the anchor rod and the coupling hole 200 can be integrated.

[0059] like Figure 7 As shown, the anchor rod of the fifth embodiment is the anchor rod of the fourth embodiment combined with the anchor rod of the second embodiment including the second epoxy resin bag 151. By including both the second epoxy resin bag 150 and the third epoxy resin bag 151, a stronger bonding force can be provided.

[0060] The anchor bolt of the fifth embodiment is a wedge-shaped anchor bolt. By rotating the nut 111 , as the expansion head 170 connected to the threaded portion 110 approaches the nut side, the expansion sleeve 130 is expanded, thereby breaking the third epoxy resin bag 152 .

[0061] In the anchor bolt of the fifth embodiment, the third epoxy resin bag 152 may be provided to partially surround the expansion head 170. As the diameter of the expansion head 170 gradually widens, the expansion sleeve 130 may be deployed along the expansion head 170. The expansion sleeve 130 deployed through the expansion head 170 may break the third epoxy resin bag 152 surrounding one side of the expansion head 170.

[0062] In addition, the second epoxy resin bag 151 may be located at the lower side of the gasket 112 and surround the outer side of the main body 120. An anti-push component 160 may also be included at the boundary between the main body 120 and the expansion sleeve 130. The anti-push component 160 is located at the lower side of the second epoxy resin bag 151, and when the nut 111 rotates, the second epoxy resin bag 151 may be prevented from being pushed toward the expansion sleeve 130. In the process of rotating the nut 111 toward the gasket 112 to fix it, the pressure is transmitted to the second epoxy resin bag 151 and it may be broken.

[0063] As in the fourth embodiment, the anchor rod may be effectively utilized by including only the third epoxy resin bag 152 , and in the anchor rod of the fourth embodiment, in addition to the third epoxy resin bag 152 , only the second epoxy resin bag 151 may be effectively utilized.

[0064] In addition, the fifth embodiment including the second epoxy resin bag 151 and the third epoxy resin bag 152 may also be effectively utilized.

[0065] 2. Description of anchor construction method

[0066] Reference Figures 1 to 5 , a construction method using the anchor rod 100 of the present invention is described.

[0067] In the construction method using the anchor rod 100, the anchor rod 100 is inserted into the coupling hole 200. First, the coupling hole 200 is drilled using a drill bit or the like at the position where the anchor rod 100 is to be coupled to the structure 250. The drilling diameter is a size that can be inserted into the anchor rod 100 of the present invention, and it is preferred that the drilling is performed in a manner that is not too wide. In addition, a hole is drilled on the structure 250 to be fixed so that the threaded portion 110 of the anchor rod 100 can be inserted.

[0068] The anchor rod 100 except the nut 111 and the washer 112 is inserted into the punched coupling hole 200 and the structure 250. The washer 112 for dispersing pressure and protecting the surface of the structure 250 is inserted into the threaded portion 110, and the nut 111 is rotated toward the washer 112 to fix the structure 250.

[0069] In the second and third embodiments, when the nut 111 is rotated toward the washer 112, the pressure is transmitted to the second epoxy resin bag 151 and the bag is broken. At this time, when the nut 111 is rotated, the second epoxy resin bag 151 is prevented from being pushed toward the expansion sleeve 130 by the anti-thrust component 160. Therefore, the second epoxy resin bag 151 is broken, and the epoxy resin 150' inside the broken second epoxy resin bag 151 can flow out between the anchor rod 100 and the coupling hole 200.

[0070] The upper portion of the pin 140 protruding to the outside of the threaded portion 110 is struck with a striking tool such as a hammer. While striking, the tip of the pin 140 located in the hollow of the main body 120 can pass through the hollow of the expansion sleeve 130. The expansion sleeve 130 is expanded by the pin 140, and the expansion sleeve 130 is pushed into the inner side of the coupling hole 200, and the anchor rod 100 can be firmly fixed in the coupling hole 200 by the hook force and the friction force.

[0071] At the same time, the first epoxy resin bag 150 located at the lower part of the pin 140 can be broken. The first epoxy resin bag 150 can be broken by the impact of the pin 140 passing through the expansion sleeve 130. In addition, since the expansion sleeve 130 is expanded by the pin 140, the shape of the expansion sleeve 130 changes, thereby, the first epoxy resin bag 150 can be broken.

[0072] The epoxy resin 150' in the broken first epoxy resin bag 150 flows out and fills between the anchor rod 100 and the coupling hole 200, thereby achieving integration. In particular, the epoxy resin 150' can firmly fix the main body 120, the expansion sleeve 130 and the coupling hole 200. The epoxy resin 150' can solidify after a certain period of time.

[0073] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 , a construction method of an anchor rod using another embodiment of the present invention is described in detail.

[0074] The anchor is inserted into the coupling hole 200. First, a coupling hole 200 is drilled using a drill bit or the like at a location where the anchor is to be used to couple the structure 250. The drilling diameter is a size that allows the anchor of the present invention to be inserted, and preferably, the hole is drilled in a manner that is not too wide. In addition, a hole is drilled on the structure 250 to be fixed so that the threaded portion 110 of the anchor can be inserted.

[0075] The anchor rod excluding the nut 111 and the washer 112 is inserted into the punched coupling hole 200 and the structure 250. The washer 112 for dispersing pressure and protecting the surface of the structure 250 is inserted into the threaded portion 110, and the nut 111 is rotated toward the washer 112 to fix the structure 250.

[0076] While the nut 111 is rotated and fixed, the pressure is transmitted to the second epoxy resin bag 151 and it is broken. At this time, when the nut 111 is rotated, the anti-push component 160 can prevent the second epoxy resin bag 151 from being pushed toward the expansion sleeve 130. The second epoxy resin bag 151 is broken, and the epoxy resin 150' inside the broken second epoxy resin bag 151 can flow out between the anchor rod 100 and the coupling hole 200.

[0077] When the nut 111 is rotated, the expansion head 170 integrally connected to the threaded portion 110 rises in the opposite direction of the coupling hole 200. As the expansion head 170 approaches the nut 111 side, the expansion sleeve 130 can be expanded through the slit 131. The expanded expansion sleeve 130 is firmly fixed to the wall surface of the coupling hole 200 by the hook force and friction force.

[0078] At this time, the third epoxy resin bag 152 located on one side of the expansion head 170 is subjected to the pressure of the unfolded expansion sleeve 130 and can be broken.

[0079] The epoxy resin 150' in the broken third epoxy resin bag 152 flows out and fills between the anchor rod and the coupling hole 200, thereby achieving integration. In particular, the epoxy resin 150' can firmly fix the main body 120, the expansion sleeve 130 and the coupling hole 200. The epoxy resin 150' can solidify after a certain period of time.

[0080] In the above, in this specification, the embodiments shown in the accompanying drawings are described so that those skilled in the art can easily understand and reproduce the present invention, but this is only exemplary, and those skilled in the art should understand that various modifications can be made to the embodiments of the present invention and other equivalent embodiments can be realized. Therefore, the protection scope of the present invention should be determined by the claims.

An anchor rod (100) inserted into a coupling hole (200), comprising: A hollow threaded portion (110), wherein the outer peripheral surface of the threaded portion comprises an external thread; A nut (111) threadably coupled to the threaded portion (110); A hollow main body (120) located below the threaded portion (110); An expansion sleeve (130) is located at the lower side of the main body (120), the hollow diameter of the expansion sleeve gradually decreases as it approaches the end, and the expansion sleeve also includes at least one slit (131) so that it can be expanded; A pin (140) is inserted into the hollow of the threaded portion (110), the main body (120) and the expansion sleeve (130); A first breakable epoxy resin bag (150) containing epoxy resin (150') and wrapping the outer circumference of the expansion sleeve (130); a second breakable epoxy resin bag (151) containing epoxy resin (150') and surrounding the outside of the main body (120); and The anti-push component (160) is located at the lower side of the second epoxy resin bag (151) to prevent the second epoxy resin bag (151) from being pushed toward the expansion sleeve (130). The first epoxy resin bag (150) and the second epoxy resin bag (151) are provided with cutouts (155) at regular intervals. When the expansion sleeve (130) is expanded by the pin (140), the first epoxy resin bag (150) is broken by the expanded expansion sleeve (130), and the epoxy resin (150') can flow out evenly when broken. The epoxy resin (150') flows out at an even position through the cutout (155') without being biased to one side, so that the anchor rod and the combination hole (200) can be integrated. When the nut (111) rotates, the anti-thrust component (160) prevents the second epoxy resin bag (151) from being pushed toward the expansion sleeve (130). In the coupling hole (200), the second epoxy resin bag (151) is crushed between the upper part of the anti-thrust component (160) and the lower part of the nut (111). The epoxy resin (150') flows out at an equal position through the incision (155') without being biased to one side, so that the anchor rod can be integrated with the coupling hole (200).

2. A construction method using the anchor rod (100) according to claim 1, wherein: The anchor rod (100) is inserted into the coupling hole (200) and comprises: Step (a), punching the combining hole (200); Step (b), inserting the anchor rod (100) into the coupling hole (200); Step (c), rotating the nut (111) toward the coupling hole (200); Step (d), simultaneously with step (c), breaking the second epoxy resin bag (151) by rotating the nut (111); Step (e), the epoxy resin (150') inside the broken second epoxy resin bag (151) flows out; Step (f), striking the pin (140); Step (g), unfolding the expansion sleeve (130) and fixing it in the coupling hole (200) by means of the pin (140); Step (h), simultaneously with step (g), breaking the first epoxy resin bag (150) by expanding the expansion sleeve (130); and Step (i), the epoxy resin (150') inside the broken first epoxy resin bag (150) flows out, so that the anchor rod (100) and the coupling hole (200) are integrated.
