Description

Technical Field

[0001] The utility model relates to the technical field of road bridge crack reinforcement structures, in particular to a road bridge crack reinforcement structure. Background Art

[0002] The reinforcement structure of road and bridge cracks is an important aspect in the field of road and bridge maintenance technology. When cracks appear on roads and bridges, in order to ensure their structural safety and extend their service life, appropriate reinforcement structures need to be used for repair. Common reinforcement methods include grouting, filling, surface spraying and bonding steel plate sealing. Grouting is to inject resin or cement materials into the cracks to improve waterproofness and durability. The filling method is suitable for wider cracks, which is achieved by chiseling grooves along the cracks and embedding bonding materials. The surface spraying method is to spray a cement mortar protective layer on the crack surface to seal the cracks. The bonding steel plate sealing method is to bond steel plates at the cracks and pressurize them with expansion bolts.

[0003] The filling method requires chiseling grooves in the cracks for repair. After chiseling grooves, the cracks will become larger. Therefore, support columns need to be set inside during the repair to enhance the support. Most of the existing support methods are installed in the grooves through expansion bolts. If the grooves are large, this method can be easily implemented. If the grooves are small, it is more difficult to implement. If the support columns are not installed, the support is insufficient.

[0004] To this end, we propose a road bridge crack reinforcement structure to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a road bridge crack reinforcement structure. When using the road bridge crack reinforcement structure, the road bridge crack reinforcement structure is also operated on the filling method. After the groove is chiseled, a cross support rod slightly shorter than the crack is embedded in the groove, and the threaded tube on one side is extended in a rotational manner, so that the cross support rod is supported in the crack. At the same time, the support tubes on both sides of the cross support rod are extended in the same way to both sides of the crack for support. Finally, the support rod is installed on the support tube to contact the crack ground, so as to complete the installation of the support column. After filling each layer in turn, the crack can be repaired. When using this method, it is more convenient to install the support frame, and the support frame can support from multiple points at the same time. The crack is reinforced and repaired in conjunction with the filler, which is more convenient and quick to use, so as to solve the problems raised in the above-mentioned background technology.

[0008] In a further embodiment, one end of the transverse support rod contacts the side surface of the crack body, and the other end contacts the other side surface of the crack body through an extended threaded barrel.

[0009] In a further embodiment, the externally connected threaded columns are symmetrically arranged on both sides of the cross support rod, and a plurality of them are arranged on each side.

[0010] In a further embodiment, the vertical support rod is arranged to be attached to the support tube, and the lower end of the vertical support rod is in contact with the bottom of the crack body.

[0024] After grooving, first select a suitable transverse support rod 2 so that it can be embedded in the crack body 1 and can move. At this time, rotate the extended threaded tube 7, move on the threaded shaft 6 to support the transverse support rod 2 to the crack body 1, and rotate the support tube 9 on the external threaded columns 8 on both sides to make the support tube 9 contact the inner walls on both sides of the crack body 1 for support. At this time, the cross-sectional support has been installed, and a threaded hole 10 is provided on the support tube 9. A vertical support rod 11 is installed on the threaded hole 10. The middle end of the vertical support rod 11 is provided with a thread, and it is rotated to contact the ground of the crack body 1. Due to the different depths of the crack body 1, the height of the vertical support rod 11 is not higher than the surface of the crack body 1. After the vertical support rod 11 is installed, the overall support is installed, and then filled in sequence. First, the cushion layer 3 is filled to the bottom layer. The cushion layer 3 is the first layer of material directly filled into the crack. It should have good permeability and adhesion, be able to fill the cracks tightly, and form a good bond with the surrounding concrete or wall materials; common bottom filling materials include mortar, epoxy resin, mineral powder, etc.; the next is the middle layer 4, which is used to enhance the strength of the crack area or provide additional support. Fiber reinforcement materials can be used to increase the tensile strength of the crack area. The top layer 5 is the last part of the filling, which is used to smooth the surface of the crack and make it consistent with the surrounding wall or concrete surface. This layer can use similar materials to the bottom filling material, but should pay more attention to its smoothness and appearance. Tools such as wet-bright scrapers or sandpaper can be used to smooth the surface to ensure that there is no obvious difference between the filled crack and the surrounding surface.

[0025] The working principle of the utility model is as follows: as shown in the figure, the crack body 1 is grooved, and the hand can enter the groove after the chiseling; and after the groove is cut, first select a suitable horizontal support rod 2 so that it can be embedded in the crack body 1 and can move, then rotate the extended threaded tube 7, move on the threaded shaft 6 to support the horizontal support rod 2 to the crack body 1, and rotate the support tube 9 on the external threaded column 8 on both sides, so that the support tube 9 is in contact with the inner walls on both sides of the crack body 1 for support, at this time the cross-sectional support has been installed, and a threaded hole 10 is provided on the support tube 9, and a vertical support rod 11 is installed on the threaded hole 10, and the middle end of the vertical support rod 11 is provided with a thread, and it is rotated to contact the ground of the crack body 1, because the depth of the crack body 1 is different, for this reason the height of the vertical support rod 11 is not higher than the surface of the crack body 1, and after the vertical support rod 11 is installed, the overall support is installed, and then filled in sequence, first the cushion layer 3, fill to the bottom layer, the cushion layer 3 is the first layer of material directly filled into the crack. It should have good permeability and adhesion, be able to fill the cracks tightly, and form a good bond with the surrounding concrete or wall materials; common bottom filling materials include mortar, epoxy resin, mineral powder, etc.; the next is the middle layer 4, which is used to enhance the strength of the crack area or provide additional support.
