Description

Technical Field

[0001] This application belongs to the technical field of building structure repair, specifically relating to a structural crack sealing structure. Background Technology

[0002] Structural cracks in the main structure can cause water seepage and quality problems, affecting the building's functionality and lifespan, thereby reducing the building's safety and durability.

[0003] In existing technologies, structural cracks are sealed by chiseling V-grooves at the location of the cracks and filling them with waterproof sealant. However, this method is prone to causing secondary cracking of the main structure at the original crack location due to structural vibration or settlement, resulting in re-leakage. Utility Model Content

[0004] The purpose of this application is to provide a structural crack sealing structure to improve the reliability of structural crack sealing structures.

[0005] To achieve the above objectives, this application provides a structural crack sealing structure, comprising:

[0006] A fishbone-shaped component is used to embed within and traverse the structural crack to divide the structural crack into an upper filling area and a lower filling area along the depth direction of the structural crack.

[0007] A repair layer is used to fill the upper filling area;

[0008] A waterproof layer is used to fill the lower filling area.

[0009] In some embodiments, the fishbone-shaped component includes:

[0010] The main rod extends along the width direction of the crack in the structure;

[0011] There are multiple primary support rods arranged on the main rod.

[0012] In some embodiments, all the primary struts are divided into two groups, with the two groups of primary struts respectively arranged on both sides of the main strut.

[0013] In some embodiments, all the primary struts in the same group are arranged parallel to each other at intervals;

[0014] In some embodiments, the two sets of primary support rods are symmetrically arranged on both sides of the main rod.

[0015] In some embodiments, the angle between the axis of the primary support rod and the axis of the main rod is in the range of 30° to 60°.

[0016] In some embodiments, the main rod extends along the width direction of the structural crack from the edge of the structural crack and the extension length ranges from 90mm to 110mm.

[0017] In some embodiments, the number of the fishbone-shaped components is multiple, and the multiple fishbone-shaped components are arranged at intervals along the extension direction of the structural crack.

[0018] In some embodiments, the spacing between adjacent herringbone-shaped members ranges from 250 mm to 350 mm.

[0019] In some embodiments, the distance between the fishbone-shaped component and the surface of the main structure along the depth direction of the structural crack is in the range of 3cm to 5cm.

[0020] In some embodiments, the repair layer comprises epoxy repair putty;

[0021] In some embodiments, the waterproof layer comprises polyurea grout.

[0022] The structural crack sealing structure provided in this application has the following beneficial effects through the above technical solution:

[0023] A herringbone-shaped member embedded in the structural crack reinforces the main structural components on both sides of the crack laterally. A repair layer is then filled into the upper filling area of ​​the crack to bond the main structural components on both sides, further reinforcing the structure. A waterproof layer filled into the lower filling area of ​​the crack serves to prevent leakage. In this application, the herringbone-shaped member and the repair layer provide dual reinforcement to the main structural components on both sides of the crack, thereby preventing secondary cracking caused by structural vibration or settlement.

[0031] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0032] The terminology of the structural crack sealing structure according to this application is described below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, a specific embodiment of this application provides a structural crack sealing structure 100, which includes a fishbone-shaped component 2, a repair layer 1, and a waterproof layer 3. The fishbone-shaped component 2 is embedded in the structural crack 200 and arranged transversely to divide the structural crack 200 into an upper filling area and a lower filling area along the depth direction of the structural crack 200. The repair layer 1 is used to fill the upper filling area, and the waterproof layer 3 is used to fill the lower filling area.

[0034] During long-term use, structural cracks 200 may appear in the main structure 300 of a building. Water can enter the interior of the main structure 300 through these cracks, causing erosion and rusting of the reinforcing steel. This seriously affects the safety and durability of the building. In this application, the structural cracks 200 are sealed using a waterproof layer 3 and a repair layer 1. Furthermore, the main structure 300 on both sides of the crack is reinforced by a herringbone-shaped component 2 and the repair layer 1, thereby strengthening the connection between the main structure 300 and the crack and preventing secondary cracking due to structural vibration or settlement. This improves the reliability of the structural crack sealing structure 100.

[0035] After the structural crack 200 is generated, the main structural members 300 on both sides of the structural crack 200 may continue to move away from each other, causing the crack to expand and grow. The fishbone-shaped member 2 in this application is made of high-strength material, such as steel. The fishbone-shaped member 2 is arranged to cross the structural crack 200 to tie the main structural members 300 on both sides of the structural crack 200, so as to prevent the structural crack 200 from continuing to expand. The repair layer 1 and the waterproof layer 3 also have an adhesive effect to further tie the main structural members 300 on both sides of the structural crack 200. At the same time, the fishbone-shaped member 2 is connected to the main structural member 300 to strengthen the connection strength between the fishbone-shaped member 2 and the main structural member 300, thereby improving the reliability of the structural crack sealing structure 100.

[0036] like Figure 3 As shown in the specific embodiment of this application, the fishbone-shaped component 2 includes a main rod 21 and primary support rods 22. The main rod 21 extends along the width direction of the structural crack 200 and penetrates the structural crack 200, with both ends embedded in the structural body 300 on both sides of the structural crack 200, so as to play the main bridging role and improve the reliability of the structural crack sealing structure 100. There are multiple primary support rods 22 arranged on the main rod 21. The primary support rods 22 can increase the contact area between the fishbone-shaped component 2 and the structural body 300 to strengthen the connection strength between the fishbone-shaped component 2 and the structural body 300, thereby improving the reliability of the structural crack sealing structure 100.

[0037] At the same time, the primary support rod 22 can also increase the contact area between the fishbone-shaped component 2 and the repair layer 1 and the waterproof layer 3, so as to strengthen the connection strength between the fishbone-shaped component 2 and the main structure 300.

[0038] like Figure 3 As shown, in some embodiments, all primary support rods 22 are divided into two groups, and the two groups of primary support rods 22 are respectively arranged on both sides of the main rod 21 to further increase the contact area between the fishbone-shaped component 2 and the main body 300, so as to strengthen the connection strength between the fishbone-shaped component 2 and the main body 300, thereby improving the reliability of the structural crack sealing structure 100.

[0039] Specifically, all primary support rods 22 in the same group are arranged parallel to each other at intervals, and / or, two groups of primary support rods 22 are symmetrically arranged on both sides of the main rod 21. The primary support rods 22 and the main rod 21 are manufactured as a single piece using mold processing. The regular shape facilitates production and processing, thus enabling mass production. Furthermore, the embedding of the herringbone-shaped component 2 requires the construction of an embedding groove with the same shape as the herringbone-shaped component 2 at the structural crack 200. The regular shape facilitates the rapid excavation of the embedding groove, thus enabling rapid construction.

[0040] Furthermore, the two sets of primary support rods 22 are located in the same plane. In other words, the bottom of the groove of the fishbone-shaped component 2 only needs to be excavated to a uniform depth. Specifically, the distance between the fishbone-shaped component 2 and the surface of the main structure 300 along the depth direction of the structural crack 200 is 3cm to 5cm, that is, the groove depth of the groove is 3cm to 5cm.

[0041] like Figure 3 As shown, in some embodiments, the first included angle between the axis of the primary support rod 22 and the axis of the main rod 21 ranges from 30° to 60°. In other words, the primary support rod 22 is inclinedly arranged on the main rod 21 to increase the contact area between the fishbone-shaped member 2 and the main structure 300, thereby strengthening the connection strength between the fishbone-shaped member 2 and the main structure 300.

[0042] Furthermore, the two sets of primary support rods 22 are symmetrically arranged in the same plane. In other words, the second included angle between the axes of the two primary support rods 22 connected to the same position on both sides of the main rod 21 ranges from 60° to 120°.

[0043] like Figure 1 As shown, in some embodiments, the main rod 21 extends along the width direction of the structural crack 200 beyond the edge of the structural crack 200 and the extension length ranges from 90mm to 110mm, so as to ensure that the main rod 21 and the first-level support rod 22 can fully contact the main body 300, thereby strengthening the connection strength between the fishbone-shaped component 2 and the main body 300.

[0044] It should be noted that the fishbone-shaped component 2 in the specific embodiments of this application can also be provided with secondary support rods, tertiary support rods, etc., to further strengthen the contact area between the fishbone-shaped component 2 and the main body 300, thereby strengthening the connection strength between the fishbone-shaped component 2 and the main body 300.

[0045] like Figure 1 As shown, in some embodiments, the number of fishbone-shaped components 2 is multiple and the multiple fishbone-shaped components 2 are arranged at intervals along the extension direction of the structural crack 200, thereby achieving the reinforcement of the entire structural crack 200.

[0046] Specifically, the spacing between adjacent fishbone-shaped components 2 is 250mm to 350mm, so as to achieve a reasonable arrangement of multiple fishbone-shaped components 2, thereby making full use of each fishbone-shaped component 2 to reinforce the structural crack 200, and thus reducing the number of fishbone-shaped components 2 required.

[0047] Furthermore, the second included angles on two adjacent herringbone-shaped members 2 are oriented in opposite directions, so that the two adjacent herringbone-shaped members 2 can balance the forces applied to the main body of the structure 300 in other directions except for the force along the width direction of the structural crack 200.

[0048] In some embodiments, the repair layer 1 includes epoxy repair putty, which has good adhesion properties, so that the fishbone-shaped component 2 is integrated with the main structure 300 and seals the embedded seam and structural crack 200, thereby improving the waterproof performance and reliability of the structural crack sealing structure 100.

[0049] In some embodiments, the waterproof layer 3 includes a polyurea grout, which has good waterproofing properties, to provide double sealing with epoxy repair putty, thereby improving the waterproofing performance of the structural crack sealing structure 100.

[0050] The construction method of the structural crack sealing structure 100 provided in the specific embodiments of this application is described below:

[0051] First, embedding joints connected to the structural crack 200 are cut on the main structural body 300 on both sides of the structural crack 200. The embedding joints are about 3cm to 5cm deep and their shape is consistent with the shape of the fishbone-shaped component 2. Second, the embedding joints and the structural crack 200 are cleaned and the fishbone-shaped component 2 is installed into the embedding joints. Then, epoxy repair putty is filled into the upper filling area. Next, holes are drilled on the main structural body 300 on both sides of the structural crack 200 to connect to the lower filling area, and grouting nozzles are installed in the grouting holes. Then, polyurea grout is injected into the lower filling area through the grouting nozzles. Finally, the grouting nozzles are removed and the grouting holes are sealed with epoxy repair putty.

[0052] The structural crack sealing structure 100 provided in the specific embodiments of this application has a good bridging and reinforcement effect, and adopts double reinforcement and leakage sealing of repair layer 1 and waterproof layer 3, thereby improving the reliability of structural crack sealing structure 100 to avoid secondary cracking and leakage of structural crack 200, and thus improving the safety and durability of the building.
