Detailed Embodiments

[0024] The following detailed embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices, and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of the present application can be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0025] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0026] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, it can be directly "on" the other element, "connected to" the other element, "bonded to" the other element, "above" the other element, or "covering" the other element, or there can be one or more other elements intervening between them. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening between them.

[0027] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0028] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, the first component, element, region, layer, or part described in the examples herein could also be termed the second component, element, region, layer, or part without departing from the teachings of the examples.

[0029] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0030] The terms used herein are for describing various examples only and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprising", "including" and "having" enumerate the stated features, quantities, operations, components, elements and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0031] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Accordingly, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0032] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. Moreover, although the examples described herein have various configurations, other configurations are possible, as will be apparent after understanding the disclosure of the present application.

[0033] The following will be combined with Figures 1 to 4 to describe the mortar-wrapped rigid joint carbon fiber grid reinforcement system of the present application. In Figures 1 to 4 the first direction L1, the second direction L2 and the third direction L3 are perpendicular to each other in pairs.

[0034] As Figure 1 shown, the mortar-wrapped rigid joint carbon fiber grid reinforcement system includes a carbon fiber grid 1 and a plurality of anchoring assemblies 3. Each anchoring assembly 3 includes a first predetermined number of anchor members 2 arranged at intervals along a predetermined direction S. The carbon fiber grid 1 includes a plurality of first ribs 11 and a plurality of second ribs 12. The plurality of first ribs 11 all extend along the first direction L1, the plurality of first ribs 11 are arranged at intervals along the second direction L2, the plurality of second ribs 12 all extend along the second direction L2, the plurality of second ribs 12 are arranged at intervals along the first direction L1, any one of the first ribs 11 intersects with the plurality of second ribs 12 respectively, and the anchor members 2 are all arranged at the intersections of the first ribs 11 and the second ribs 12. The anchor members 2 are used to connect with the member to be reinforced 6; the plurality of anchoring assemblies 3 are arranged at intervals along the predetermined direction S, and the predetermined direction S intersects with the first direction L1 and the second direction L2 respectively.

[0035] In the mortar-wrapped rigid joint carbon fiber grid reinforcement system of the present application, the anchor 2 is arranged at the intersection of the first reinforcement 11 and the second reinforcement 12, so that the anchor 2 can apply force to the intersecting first reinforcement 11 and second reinforcement 12 simultaneously, thereby ensuring the stability of the forces on the intersecting first reinforcement 11 and second reinforcement 12. At the same time, each anchoring assembly 3 includes a plurality of anchors 2 arranged at intervals along a predetermined direction S, and the predetermined direction S intersects with the first direction L1 and the second direction L2 respectively. This makes the two adjacent anchors 2 in the first anchoring assembly 3 and the two adjacent anchors 2 in the second anchoring assembly 3 in two adjacent anchoring assemblies arranged in a parallelogram, thereby ensuring the uniformity of the anchoring of the entire carbon fiber grid 1 by the plurality of anchoring assemblies 3. In this way, the carbon fiber grid 1 is uniformly stressed, reducing the risk of deformation of the carbon fiber grid 1, and thus ensuring the strengthening effect of the reinforced concrete structure.

[0036] Optionally, the number of anchors 2 in each anchoring assembly 3 can be the same or different. For example, the number of anchors 2 included in the anchoring assembly 3 can be two, three or more.

[0037] Optionally, the member to be reinforced 6 can be a concrete beam-slab or the like.

[0038] Furthermore, the plurality of anchors 2 in each anchoring assembly 3 are arranged in a straight line, and the plurality of anchoring assemblies 3 are arranged at equal intervals along the second direction L2. In this way, the uniformity of the arrangement of the anchors 2 on the carbon fiber grid 1 can be further improved, and then the uniformity of the anchoring of the entire carbon fiber grid 1 by the plurality of anchors 2 can be improved.

[0039] Preferably, the distance between two adjacent anchors 2 in each anchoring assembly 3 is equal. In this way, the two adjacent anchors 2 in the first anchoring assembly 3 and the two adjacent anchors 2 in the second anchoring assembly 3 in two adjacent anchoring assemblies are arranged in a rhombus, further improving the uniformity of the anchoring of the entire carbon fiber grid 1 by the plurality of anchors 2.

[0040] In the embodiment of the present application, as Figure 1 shown, the mortar-wrapped rigid joint carbon fiber grid reinforcement system further includes a fixing assembly 4. The fixing assembly 4 includes a second predetermined number of anchors 2. The anchors 2 included in the fixing assembly 4 are arranged at the intersections of the first reinforcement 11 and the second reinforcement 12 at the edges located in the second direction L2, and the plurality of anchors 2 included in the fixing assembly 4 are arranged at intervals along the first direction L1. In this way, the fixing assembly 4 can anchor the end of the carbon fiber grid 1 in the first direction L1, thereby ensuring the stability of the anchoring of the carbon fiber grid 1.

[0041] Optionally, the number of anchors 2 included in the fixing assembly 4 can be 5, 6 or more.

[0042] Preferably, the number of the fixing components 4 is two, and the two fixing components 4 are respectively arranged at both ends of the carbon fiber grid 1 in the second direction L2. In this way, both ends of the carbon fiber grid 1 in the first direction L1 are respectively anchored by the anchor members 2 in the two fixing components 4, further improving the stability of the anchoring of the carbon fiber grid 1.

[0043] In the embodiment of the present application, as Figure 2 shown, the mortar-wrapped rigid joint carbon fiber grid reinforcement system may include a plurality of carbon fiber grids 1, any two adjacent carbon fiber grids 1 in the plurality of carbon fiber grids 1 are connected, and an anchoring component 3 is arranged on each carbon fiber grid 1. In this way, the number of the carbon fiber grids 1 can be selected based on the size of the member 6 to be reinforced to meet the reinforcement requirements of different members 6 to be reinforced.

[0044] Further, in the plurality of carbon fiber grids 1, two adjacent carbon fiber grids 1 overlap, and the overlapping part is tied by a tying part 5, so as to fix the two carbon fiber grids 1. Taking two carbon fiber grids 1 adjacent to each other in the first direction L1 as an example, the second ribs 12 at the edge in the first direction L1 of the first carbon fiber grid 1 overlap with the second ribs 12 at the edge in the first direction L1 of the second carbon fiber grid 1, and are tied and fixed by the tying part 5, the end of the first rib 11 in the first carbon fiber grid 1 overlaps with the end of the first rib 11 in the second carbon fiber grid 1, and is tied and fixed by the tying part 5, so as to fix the two carbon fiber grids 1.

[0045] Optionally, the tying part 5 may be a binding wire.

[0046] In the embodiment of the present application, as Figure 4 shown, the first rib 11 may include a plurality of carbon fiber plates 111, the second rib 12 includes a plurality of basalt fiber plates 121, the number of the carbon fiber plates 111 is one more than the number of the basalt fibers, and the carbon fiber plates 111 and the basalt fiber plates 121 are arranged alternately, so that a basalt fiber plate 121 is arranged between any two adjacent carbon fiber plates 111. The connection part of the first rib 11 and the second rib 12 formed in the above form is a rigid joint, which has sufficient structural strength to prevent the first rib 11 and the second rib 12 from being displaced.

[0047] Further, the carbon fiber board 111 and the basalt fiber board 121 are connected by a resin connection part. Specifically, the carbon fiber board 111 and the basalt fiber board 121 are impregnated with resin, and then the connection parts to be joined of the carbon fiber board 111 and the basalt fiber board 121 are bonded. After the resin is cured, a resin connection part is formed, realizing the connection of the carbon fiber board 111 and the basalt fiber board 121. By connecting the carbon fiber board 111 and the basalt fiber board 121 in the above manner, dislocation at the intersection can be avoided.

[0048] Optionally, the number of carbon fiber boards 111 can be 5, and the number of basalt fiber boards 121 can be 4.

[0049] In the embodiment of the present application, as Figure 3 shown, the anchor 2 includes a first fixing part 21, a second fixing part 22 and a connecting part 23. The first fixing part 21 and the second fixing part 22 are respectively connected to both sides of the connecting part 23 in the third direction L3. The ends of the first fixing part 21, the second fixing part 22 and the connecting part 23 are flush in the first direction L1. The length of the connecting part 23 in the first direction L1 is less than the length of the first fixing part 21 in the first direction L1, and the length of the connecting part 23 in the first direction L1 is less than the length of the second fixing part 22 in the first direction L1. The ends of the first fixing part 21, the second fixing part 22 and the connecting part 23 are flush in the second direction L2. The length of the connecting part 23 in the second direction L2 is less than the length of the first fixing part 21 in the second direction L2, and the length of the connecting part 23 in the second direction L2 is less than the length of the second fixing part 22 in the second direction L2. Thus, the connecting part 23 divides the space between the first fixing part 21 and the second fixing part 22 into a first limiting channel and a second limiting channel. The first limiting channel extends along the first direction L1, and the second limiting channel extends along the second direction L2. A part of the first rib 11 is located in the first limiting channel, a part of the second rib 12 is located in the second limiting channel, and the intersection of the first rib 11 and the second rib 12 is located at the intersection of the first limiting channel and the second limiting channel. Then, the fastener 8 passes through the first fixing part 21, the second fixing part 22, the connecting part 23 and the member to be strengthened 6, thereby realizing the fixation of the carbon fiber grid 1.

[0050] Optionally, the fastener 8 can be a rivet.

[0051] Further, as Figure 5 shown, the mortar - wrapped rigid - joint carbon fiber grid strengthening system further includes a mortar layer 7. The mortar layer 7 is connected to the member to be strengthened 6, and the mortar layer 7 covers the carbon fiber grid 1, the anchor 2 and the fastener 8, thereby realizing the strengthening of the member to be strengthened 6.

[0052] Preferably, the thickness of the mortar layer 7 is greater than or equal to 25 mm, so as to ensure the strengthening effect on the member to be strengthened 6.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
