Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction, specifically a structure for reinforcing cracks in road and bridge construction. Background Technology

[0002] With the rapid development of urban and rural areas, the construction of roads and bridges has become increasingly common. However, after a long period of use, some structures of bridges and roads will gradually age or be damaged, such as bridge cracks. In order to ensure the safety of bridges, traditional crack repair methods are usually used, such as directly pouring concrete. Although this can fill the cracks, it cannot guarantee the structural strength of the repaired cracks and there is a high risk of secondary cracks. Furthermore, the concrete after filling cannot provide tensile force to both sides, so the effect is poor. Utility Model Content

[0003] The purpose of this utility model is to provide a structure for reinforcing cracks in road and bridge construction, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes two opposing base plates. Two fixing blocks are provided on one side of the base plate, and a fixing rod is hinged to each fixing block. A tension assembly is provided on the other side of the base plate. The tension assembly includes opposing fixing columns, each fixing column containing a one-way bearing. A connecting rod is fitted inside the one-way bearing, and a gear that engages with the end of the corresponding fixing rod is fitted on the outer diameter of the connecting rod. A fastening assembly is provided outside the base plates. The fastening assembly includes a longitudinal support arm, with transverse support arms connected to both sides of the longitudinal support arm. A tension rod located between the two base plates is provided between the longitudinal support arms, and a fixing buckle is provided at the tension rod.

[0005] Preferably, the base plate has mounting holes at its four corners, bolts are fitted into the mounting holes, and expansion tubes are installed at the bottom of the bolts below the base plate.

[0006] Preferably, the tension rod includes two sets of opposing gripping rods, each gripping rod including a vertical support rod and a horizontal support rod. One end of the vertical support rod is connected to a longitudinal support arm, and the other end is connected to the horizontal support rod. The tension rods are arranged in pairs, and the horizontal support rods are staggered to form an assembly opening. The fixing buckle is installed at the assembly opening.

[0007] Preferably, the fixing buckle includes a top plate, and a protrusion matching the assembly opening is provided below the top plate. Limiting blocks installed below the top plate are provided on both sides of the protrusion. The length of the protrusion and the two limiting blocks is greater than the width of the two transverse support rods.

[0008] Preferably, the fixing block includes two support plates vertically arranged on the base plate, a cylindrical connecting column is provided between the support plates, and the fixing rod is hinged to the connecting column.

[0009] Preferably, the end of the fixing rod facing the tensioning assembly is provided with a rack that engages with the corresponding side gear.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) When using this device, it is installed at both ends of the crack. The base plate is fixed to the road surface by expansion tubes and bolts. After the fixation is completed, the two ends are fixed by the rack of the fixing rod and the tension component. After the fixation is completed, a lateral tension is generated at both ends of the crack, which effectively prevents the crack from expanding further.

[0012] (2) In order to further increase the lateral tension, the device is also equipped with a fastening assembly outside the base plate. The longitudinal tension is further consolidated by the lateral support arm and the longitudinal support arm. At the same time, in order to increase the overall support of the device, the fastening assembly is also equipped with a tension rod. The tension rod and the fixing buckle work together to form a lateral gripping force, which enhances the stability of the entire device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 6 As shown, this utility model provides the following technical solution:

[0022] It includes two base plates arranged opposite each other, which are installed at both ends of the crack. When in use, the base plates need to be cut open and installed below the ground. There are mounting holes at the four corners of the base plates, and bolts are installed at the mounting holes. The bottom of the bolts is equipped with expansion tubes installed under the base plates. The expansion tubes help to firmly fix the base plates to ensure the stability of the subsequent devices.

[0023] Two fixing blocks are provided on one side of the base plate. Each fixing block includes two support plates vertically arranged on the base plate. A cylindrical connecting column is provided between the support plates. The fixing rod is hinged to the connecting column. The fixing block is hinged to a fixing rod. The end of the fixing rod facing the tensioning assembly is provided with a rack that cooperates with the corresponding side gear.

[0024] The other side of the base plate is provided with a tensioning assembly, which includes a fixed column arranged opposite to each other. A one-way bearing is provided inside the fixed column. A connecting rod is fitted inside the one-way bearing. One end of the connecting rod is provided with a groove that matches a hexagonal wrench. A gear that mates with the end of the corresponding fixed rod is fitted on the outer diameter of the connecting rod. When in use, the connecting rod is rotated by the wrench. The connecting rod drives the gear to rotate. The gear drives the rack to tighten and generate lateral tension, which effectively relieves the stress at the crack.

[0025] The base plate is equipped with a fastening assembly, which includes a longitudinal support arm. Transverse support arms are connected to both sides of the longitudinal support arm. A tension rod is located between the two base plates between the longitudinal support arms. A fixing buckle is provided at the tension rod. The tension rod includes two sets of opposing gripping rods, each gripping rod comprising a vertical support rod and a transverse support rod. One end of the vertical support rod is connected to the longitudinal support arm, and the other end is connected to the transverse support rod. The tension rods are arranged in pairs, with the transverse support rods staggered to form an assembly opening.

[0026] The fixing buckle is installed at the assembly port. The fixing buckle includes a top plate. A protrusion matching the assembly port is provided below the top plate. Limiting blocks installed below the top plate are provided on both sides of the protrusion. The length of the protrusion and the two limiting blocks is greater than the width of the two horizontal support rods. The width of the protrusion is greater than the width of the assembly port. When in use, the fixing buckle is hammered into the assembly port, which will generate a corresponding pulling force.

[0027] When using it, first clean both ends of the road crack and throw out an appropriate depth and size. Then fix the two base plates to both sides of the crack with bolts and expansion tubes respectively. After fixing, tighten the gear by rotating the gear tensioning device. After tightening, install the fastening components and snap the transverse support arm to the outermost side of the base plate. The tension rod of the longitudinal support arm forms the installation port. Then install the fixing buckle at the installation port. After the whole installation is completed, pour concrete.
