Technical Field
[0001] This utility model belongs to the field of highway engineering technology, and in particular relates to a structure for repairing cracks in highway curb stones. Background Technology
[0002] Road curbs are an important infrastructure component in highway engineering, used to separate lanes, guide drainage, and ensure safety. They are mainly divided into upright curbs (15-30cm high, for enhanced separation), flat curbs (low and practical, facilitating vehicle parking), and curved and barrier-free curbs (suitable for curves or special needs). Materials are primarily concrete and stone, balancing cost and durability.
[0003] Curbstones often develop cracks due to external impacts, affecting their overall stability. Some curbstones are large, making complete replacement impractical. To further improve the service life of curbstones, a road curbstone crack repair structure is needed. This structure involves adding symmetrical reinforcing bars to the inner wall of the curbstone cracks and connecting the reinforcing bars with connectors. Then, fiber mesh and filler are used to repair the cracks, thereby repairing the curbstone cracks and extending its service life. Utility Model Content

[0011] The beneficial effects of this utility model are:
[0012] This invention uses a rebar adhesive layer to fix the implanted screw in the inner cavity of the insertion hole. Then, a nut block is used to fix the hole plate and fiber mesh layer to the surface of the implanted screw. Subsequently, a marble adhesive layer and an epoxy resin adhesive layer are used to fill the inner cavity of the crack, thereby achieving the purpose of adding symmetrical rebar to the inner wall of the curb stone crack. The rebar is connected by a connector, and then the crack is repaired by fiber mesh and filler, thus repairing the curb stone crack and extending its service life.

[0023] In the following description, embodiments of the road curbstone crack repair structure of the present invention will be described with reference to the accompanying drawings. Example 1
[0024] Figure 1-4 This invention illustrates a road curbstone crack repair structure according to an embodiment of the present invention. It includes an insertion hole 1 and a rectangular groove 2 formed in the inner wall of the curbstone crack. An implantable screw 3 is inserted into the inner cavity of the insertion hole 1. A rebar adhesive layer 4 is filled between the implantable screw 3 and the inner wall of the insertion hole 1. A support strip 5 is integrally formed on the surface of the implantable screw 3. The support strip 5 increases the contact area between the implantable screw 3 and the rebar adhesive layer 4, improving the stability of the connection and fixation between the implantable screw 3 and the inner wall of the insertion hole 1. A fixing plate 6 is integrally formed on the surface of the implantable screw 3. A perforated plate 7 and a fiber mesh layer 8 are sleeved on the surface of the implantable screw 3. The surface of the implanted screw 3 is threaded with a nut block 9, and a pad block 10 is fitted on the surface of the implanted screw 3. The pad block 10 is in contact with the fiber mesh layer 8. The pad block 10 protects the nut block 9 and the fiber mesh layer 8 by padding them apart, avoiding the situation of squeezing damage when they are in direct contact, thus ensuring the performance of the fiber mesh layer 8. The fiber mesh layer 8 and the top of the inner cavity of the rectangular groove 2 are filled with a structural adhesive layer 11. The perforated plate 7 and the crack of the curbstone are filled with an epoxy resin adhesive layer 12. The fiber mesh layer 8 and the inner wall of the rectangular groove 2 are filled with a marble adhesive layer 16. Example 2
[0025] Figure 1-4This invention illustrates a road curbstone crack repair structure according to an embodiment of the present invention, comprising an insertion hole 1 and a rectangular groove 2 formed in the inner wall of the curbstone crack; an implantation screw 3 is inserted into the inner cavity of the insertion hole 1, and a rebar adhesive layer 4 is filled between the implantation screw 3 and the inner wall of the insertion hole 1; a fixing plate 6 is integrally formed on the surface of the implantation screw 3; a perforated plate 7 and a fiber mesh layer 8 are sleeved on the surface of the implantation screw 3; a nut block 9 is threadedly connected to the surface of the implantation screw 3; an epoxy resin adhesive layer 12 is filled between the perforated plate 7 and the curbstone crack; a rectangular opening 13 is formed in the inner wall of the rectangular groove 2; the bottom of the fiber mesh layer 8 extends into the inner cavity of the rectangular opening 13; the inner wall of the rectangular opening 13 and the fiber mesh layer 8 are connected. The two sides are filled with structural adhesive layer 14. The rectangular opening 13 and the structural adhesive layer 14 fix the connection between the fiber mesh layer 8 and the bottom of the rectangular groove 2, preventing the bottom of the fiber mesh layer 8 from curling when the marble adhesive layer 16 is filled later. A wedge block 15 is inserted between the fiber mesh layer 8 and the inner wall of the rectangular opening 13. The wedge block 15 strengthens the connection between the fiber mesh layer 8 and the inner wall of the rectangular opening 13, further improving the stability of the connection between the fiber mesh layer 8 and the inner wall of the rectangular groove 2, and preventing the curling of the connection between the two. The fiber mesh layer 8 and the inner wall of the rectangular groove 2 are filled with marble adhesive layer 16.
[0026] Working Principle: In use, the user creates insertion holes 1 and rectangular grooves 2 on the inner wall of the curbstone crack. The inner wall is then cleaned. Next, the implanted screw 3 is fixed to the inner cavity of the insertion hole 1 using the anchoring adhesive layer 4. Then, a perforated plate 7 is fitted onto the surface of the implanted screw 3. An epoxy resin adhesive layer 12 is then filled between the perforated plate 7 and the inner wall of the crack. A fiber mesh layer 8 is then fitted onto the surface of the implanted screw 3, and a structural adhesive layer 11 is used to fix the fiber mesh layer 8 to the top of the inner cavity of the rectangular groove 2. The perforated plate 7 and the fiber mesh layer 8 are then fixed to the surface of the implanted screw 3 using a nut block 9. Finally, a marble adhesive layer 16 is used to fill the inner cavity of the rectangular groove 2. This process achieves symmetrical anchoring of the curbstone crack's inner wall, and the anchoring is connected using connectors. The crack is then repaired using the fiber mesh and filler, thus repairing the curbstone crack and extending its service life.
[0027] In summary, this road curbstone crack repair structure uses a rebar adhesive layer 4 to fix the implanted screw 3 into the inner cavity of the insertion hole 1. Then, the nut block 9 fixes the hole plate 7 and the fiber mesh layer 8 to the surface of the implanted screw 3. Subsequently, the inner cavity of the crack is filled with marble adhesive layer 16 and epoxy resin adhesive layer 12. This achieves the goal of adding symmetrical rebars to the inner wall of the curbstone crack, connecting the rebars with connectors, and then repairing the crack with fiber mesh and filler. This allows the curbstone crack to be repaired, thereby extending its service life.
