Description
Technical Field
[0001] The present application relates to the field of building crack treatment, and in particular to a crack treatment structure for preventing crack expansion. Background Art
[0002] There are many traditional methods for treating concrete cracks. Surface sealing method: using the capillary action of the crack to absorb low-viscosity and highly permeable repair glue; injection method: injecting low-viscosity and high-strength crack repair glue into the crack cavity at a certain pressure; pressure grouting method: pressing the grouting material into the crack cavity at a high pressure for a certain period of time; and filling and sealing method: chiseling a U-shaped or V-shaped groove on the surface of the component along the crack direction, and then filling it with modified epoxy resin or elastic caulking material.
[0003] However, the traditional crack treatment method is only to seal and fill the concrete cracks, which cannot limit the further expansion of the cracks, so the effect is poor. Utility Model Content
[0004] In order to prevent further expansion of cracks in concrete components, the present application provides a crack treatment structure for preventing crack expansion, which can generate tension between concrete components on both sides of the cracks when the cracks expand further, thereby preventing the cracks in the concrete components from becoming larger, improving the durability of the concrete components, and achieving better crack treatment effects.
[0005] The present application provides a crack treatment structure for preventing crack expansion using the following technical solution:
[0006] A crack treatment structure for preventing crack expansion includes one or more tensile members, wherein the tensile members are embedded in concrete components, the two ends of the tensile members are respectively anchored to the concrete components on both sides of the crack, and the gap between the tensile members and the concrete components and the cracks are filled with structural adhesive.
[0007] By adopting the above technical solution, when the cracks in the concrete component tend to expand further, the tensile members can form a tensile force between the concrete components on both sides of the cracks, preventing the concrete component from further expanding, avoiding the re-appearance of cracks in the concrete component and affecting the appearance, while greatly improving the durability and stability of the concrete component structure.
[0008] Optionally, the extension direction of the tensile member is perpendicular to the direction of the crack.
[0009] By adopting the above technical solution, the tension formed by the extension piece is perpendicular to the inner wall of the crack, thereby improving the force application efficiency, thereby improving the limiting effect on the crack and further improving the durability of the concrete component.
[0010] Optionally, when a plurality of tensile members are provided, the plurality of tensile members are evenly distributed along the direction of the crack.
[0011] By adopting the above technical solution, the tension applied by the tensile member to the concrete components on both sides of the crack is made more uniform.
[0012] Optionally, the tensile member includes an extension member and at least two anchor members, the extension member extends in a straight line, and both ends are located on both sides of the crack, at least two anchor members are distributed on both sides of the crack and fixed to the concrete member, and the parts of the extension member located on both sides of the crack are connected to the anchor members located on the same side of the crack.
[0013] By adopting the above technical solution, the extension piece connects the anchors anchored on both sides of the crack. When the crack has a tendency to expand further, the concrete component tends to stretch the extension piece through the anchor, so that the extension piece forms a tensile force to resist further expansion of the crack to prevent the crack from expanding.
[0014] Optionally, at least two of the anchors are evenly distributed along the extension direction of the extension member.
[0015] By adopting the above technical solution, it can be ensured that the extension piece is evenly stressed, making the structure more stable.
[0016] Optionally, the extension member includes an extension plate, and a surface of the extension plate is perpendicular to a surface of the concrete member.
[0017] By adopting the above technical solution, it is unnecessary to open a relatively wide groove in the concrete component, thereby reducing damage to the concrete component and avoiding affecting the overall stability of the concrete component.
[0018] Optionally, the extension plate body is provided with one or more through holes for the structural adhesive to flow.
[0019] By adopting the above technical solution, the structural adhesive passes through the perforations to improve the bonding effect between the extension plate and the structural adhesive, so that the extension plate and the structural adhesive are bonded as one, thereby improving the stability of the extension plate.

[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The present application embodiment discloses a crack treatment structure for preventing crack expansion, referring to Figure 1 and Figure 2 , including one or more tensile members 1, the tensile member 1 is embedded in the concrete member, and the two ends of the tensile member 1 are respectively anchored to the concrete members located on both sides of the crack, and the gap formed between the tensile member 1 and the concrete member and the crack are filled with structural adhesive.
[0033] After the structural adhesive seals the cracks on the concrete component, the surface of the concrete component can be kept intact through painting and other processes. When the cracks in the concrete component tend to expand further, the tensile member 1 can form a tensile force between the concrete components on both sides of the crack to prevent the concrete component from further expanding, avoiding the reappearance of cracks in the concrete component and affecting the appearance, while greatly improving the durability and stability of the concrete component structure.
[0034] During specific construction, the tensile members 1 can be provided in corresponding quantities according to the length of the cracks in the concrete member and the degree of cracking. Preferably, when multiple tensile members 1 are provided, the multiple tensile members 1 are evenly distributed along the crack direction, so that the tensile force applied by the tensile members 1 to the concrete members on both sides of the crack is more uniform, further improving the durability and stability of the concrete member.
[0035] Specifically, refer to Figure 1 and Figure 2 The tensile member 1 includes an extension member 11 and at least two anchor members 12. The extension member 11 is embedded in the concrete member and extends in a straight line. The two ends of the extension member 11 are located on both sides of the crack. The anchor members 12 fix the concrete members embedded on both sides of the crack. At the same time, the parts of the extension member 11 located on both sides of the crack are respectively connected to the anchor members 12 located on the same side of the crack. The extension member 11 connects the anchor members 12 anchored on both sides of the crack. When the crack has a tendency to further expand, the concrete member generates a tendency to stretch the extension member 11 through the anchor members 12, so that the extension member 11 forms a tensile force to resist further expansion of the crack to prevent the crack from expanding.
[0036] Preferably, the extension direction of the extension member 11 is perpendicular to the direction of the crack, so that the tension formed by the extension member 11 is perpendicular to the inner wall of the crack, thereby improving the force application efficiency and further improving the limiting effect on the crack.
[0037] Preferably, the anchors 12 are arranged in plurality and evenly distributed along the extension direction of the extension 11. Adding the anchors 12 can improve the force effect of the extension 11 on the concrete member, and the evenly distributed arrangement can ensure that the extension 11 is evenly stressed, making the structure more stable.
[0038] In addition, refer to Figure 3 The anchor 12 can be set in various shapes such as a cylinder, a square body, a triangular prism, etc., as long as it can form an anchoring effect in the concrete component and allow the extension piece 11 to form a pulling force between the concrete components on both sides of the crack.
[0039] Further, refer to Figure 1 The extension member 11 includes an extension plate 111, which is a strip plate structure, and the plate surface of the extension plate 111 is perpendicular to the surface of the concrete member, and the anchor 12 is fixed to the extension plate 111 to resist crack expansion. In this embodiment, the extension plate 111 is made of a carbon fiber plate.
[0040] It should be noted that in other embodiments, the extension member 11 can also be set as a rope body, a rod body, etc., as long as it can connect the two anchors 12 to form a tensile force to resist the expansion of the crack. In this embodiment, the extension plate 111 is preferably a plate structure. The plate structure has a certain rigidity compared to the rope body, and is more convenient to be embedded in the concrete member. It is also easier to control the direction, so that the extension member 11 is set perpendicular to the crack direction. The rod body needs to have a certain thickness to meet the tensile requirements. When a thicker rod body is embedded in a concrete member, a relatively wide groove needs to be opened accordingly, which is more destructive to the concrete member and may affect the overall structural strength and stability of the concrete member. By setting the plate body perpendicular to the concrete member, it can not only withstand a certain tensile load, but also does not need to open a relatively wide notch, which is convenient and stable to implement.
[0041] During the specific construction, first select the corresponding length and number of tensile members 1 according to the specific situation of the cracks, and then open a groove for accommodating the extension plate 111 and the anchor 12 on the concrete component according to the preset position, and at the same time ensure that the depth of the groove is greater than the length of the extension plate 111 perpendicular to the surface of the concrete component; then clean the floating dust in the cracks and the grooves, and then press the structural glue into the cracks and the grooves, and ensure that the cracks and the grooves are filled to exhaust the air; then insert the extension plate 111 and the anchor 12 into the grooves accordingly, and wipe off the excess structural glue; finally, it can be sealed as needed.
[0042] Further, refer to Figure 1 The extension plate 111 is provided with one or more through holes 2 through which the structural adhesive flows. By providing the through holes 2, when the extension plate 111 is inserted into the slot filled with the structural adhesive, the structural adhesive will gradually flow into the through holes 2, which facilitates the structural adhesive to flow in the slot, and at the same time makes the extension plate 111 and the structural adhesive bonded together, thereby improving the stability of the extension plate 111. The through holes 2 can be provided in various shapes as required, and can also be set to different numbers, such as Figure 4 As shown, various ways of opening the through hole 2 are shown. The through hole 2 can be opened into a long strip, or into a plurality of square holes, round holes, etc.
[0043] Further, refer to Figure 1 When there are multiple through holes 2, the multiple through holes 2 are evenly distributed on the surface of the extension plate 111. The evenly distributed through holes 2 make the bonding force between the structural adhesive and the extension plate 111 evenly distributed on the extension plate 111, further improving the stability of the connection of the extension plate 111.
[0044] The implementation principle of a crack treatment structure for preventing crack expansion disclosed in an embodiment of the present application is as follows:
[0045] By fixing the anchors 12 at both ends of the extension piece 11 to the concrete components on both sides of the crack, the extension piece 11 can form a tensile force when the crack expands to resist further expansion of the crack, thereby improving the durability of the concrete component structure. The extension piece 11 and the anchor 12 are both embedded in the concrete component and do not affect the integrity of the concrete component's appearance.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
