[0031] The following is combined with Figure 1-5 The utility model is described in further detail.

[0032] The utility model embodiment discloses a prefabricated concrete component maintenance device.

[0033] Reference Figure 1 , 3 , including a grouting component 1, a scraper 2 and a chiseling component 3. Some precast concrete components have broken corners, honeycombs, holes, exposed stones and shallow concrete defects, which need to be repaired with fine stone concrete (known technology). Before using fine stone concrete to repair, the construction personnel must chisel away the loose concrete on the surface of the holes and honeycombs through the chiseling component 3 until the dense concrete is exposed, and then carry out fine stone concrete repair. The scraper 2 is a common cement mortar scraper tool. The grouting component 1 and the chiseling component 3 are respectively located on both sides of the scraper 2 and are symmetrically distributed. One side of the grouting component 1 is fixedly connected to one side of the scraper 2, and the chiseling component 3 is fixedly connected to one side of the scraper 2. If the surface of the precast concrete component is uneven and the lines are not straight and need to be repaired, after cutting with a cutting machine, the chiseling component 3 is used to chisel away the excess precast concrete, and after repairing with fine stone concrete, the surface of the precast concrete component is repaired with slurry through the grouting component 1.

[0034] Reference Figure 1 , 2The grouting component 1 includes a sleeve 11 and a connecting pipe 12. One end of the sleeve 11 is fixedly connected to a nozzle 13. The connecting pipe 12 is sleeved inside the sleeve 11. The connecting pipe 12 can be connected to professional pressure equipment (known technology). The professional pressure equipment can be an extrusion bag. The extrusion bag can be filled with cement mortar, epoxy resin, methacrylate and other bonding materials according to needs. The construction worker can hold the handle 4 with one hand and hold the extrusion bag with the other hand to squeeze the corresponding material according to the appearance repair requirements to repair the precast concrete component.

[0035] Reference Figure 1 , 2 4. One end of the connecting pipe 12 is fixedly connected to one end of the nozzle 13. The interior of the nozzle 13 is communicated with the interior of the connecting pipe 12. Cement mortar, epoxy resin, methacrylate and other bonding materials in the professional pressure equipment can be directed into the interior of the rough surface and cracks through the nozzle 13 to repair the appearance defects of the precast concrete components.

[0036] Reference Figure 1 , 4 5. The excavating member 3 includes a flat plate 31, and metal springs 32 are fixedly connected to both sides of the flat plate 31. If a groove is chiseled at the concrete crack, the two metal springs 32 are opened and closed according to the size of the groove until the two metal springs 32 are opened and closed at a suitable angle. The direction of the excavating member 3 is controlled by the operating handle 4 to excavate the cracks on the surface of the precast concrete component. The metal springs 32 are symmetrically distributed on both sides of the flat plate 31.

[0037] Reference Figure 2 , 3 , 4, 5, the lowest end of the flat plate 31 and the lowest end of the sleeve 11 are at the same height as the lowest end of the scraper 2. By operating the handle 4 to change the directions of the scraper 2 and the flat plate 31, both the scraper 2 and the flat plate 31 can apply pressure to press the cement mortar into the appearance defects of the precast concrete components. The lowest ends of the flat plate 31 and the lowest ends of the sleeve 11 can move together with the scraper 2 to flatten the cement mortar or other bonding materials on the surface of the precast concrete components.

[0038] Reference Figure 1 , 2 , 3, 4, 5. A handle 4 is fixedly connected to the top of the scraper 2. The rough surface refers to the fact that after the component is prefabricated and poured in the factory, the local outer surface of the component is damaged by the formwork, resulting in the appearance of partially uneven surfaces or irregular dents the size of beans. The diameter of the dents is generally less than 5mm. It is repaired with cement mortar. The scraper 2 presses the extruded cement mortar into the rough surface and scrapes it flat.

[0039] The implementation principle of the concrete prefabricated component maintenance device of the utility model embodiment is:

[0040] 1. To repair the pitting and fine cracks, the construction worker operates the pressure equipment with one hand to squeeze the corresponding cement mortar to the pitting and fine cracks of the precast concrete component. After squeezing a certain amount, the worker releases the pressure equipment and controls the scraper 2 to move to the pitting and fine cracks with the other hand. After the squeezing is completed, the pressure equipment is removed and the directions of the scraper 2 and the flat plate 31 are changed by operating the handle 4. Both the scraper 2 and the flat plate 31 can apply pressure to press the cement mortar into the appearance defects of the precast concrete component, thereby repairing the precast concrete component;

[0041] 2. Repair the cracks caused by cracks on the outer surface of the precast concrete component. The construction worker changes the direction of the nozzle 13 with one hand and uses the other hand to operate the professional pressure equipment to press the bonding material into the cracks of the concrete. After the bonding material hardens, it forms a whole with the concrete. When the concrete crack needs to be chiseled into a groove, the metal spring 32 is first bent to a suitable angle to avoid the chiseled crack being too large, and then the crack is reinforced and repaired with the bonding material;

[0042] 3. Save time for replacing scrapers, chiseling knives and other tools. The flat plate 31 and the sleeve 11 are extended parts of the scraper 2. After the cementing material is squeezed into the pits and cracks, the scraping area of ​​the scraper 2 can be increased, which is conducive to reducing the time spent on repair.

[0043] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
