Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a core hole repairing device used for coring concrete components after coring and sampling. Background Art

[0002] In construction projects, in order to clarify the compressive strength of solid structural concrete, especially to provide a basis for safety assessments of existing buildings, core sampling of the solid structural concrete is required to determine the compressive strength of the core sample. As the service life of existing buildings approaches their design life, core sampling has been widely used in appraisal projects, and the repair of core holes is also very important. At present, for ordinary core holes, formwork is usually set up first, and then grouting materials and micro-expansive concrete are used for repair. However, due to the high floor height of some buildings and the fact that core samples are usually obtained by horizontal drilling equipment, pouring formwork is difficult and not easy to operate. Moreover, after the formwork is set up, it is impossible to visually detect whether the grouting materials and micro-expansive concrete are used for repair, making it difficult to achieve a good repair effect.

[0003] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0041] In the present invention, the detection tube 1.1 is used to detect whether the core hole 6 is filled with slurry.

[0044] In the present invention, before the fixed plate 1 is lifted, the lower portion of the feed pipe 2 is tied and fixed to the vertical support rod 3 through the iron wire 9 .

[0045] Preferably, a pressing groove 8 is provided on the outer side of the fixing plate 1 (ie, the back side of the adhesive layer).

[0047] Example

[0048] This embodiment is used to repair a coring hole 6 in a concrete beam member. This coring hole 6 is 5 meters high and 100 mm in diameter. The fixing plate 1 is a square foam board with a side length of 30 cm. One side of the foam board is coated with an adhesive layer, which is covered with a protective layer. The feed pipe 1.2 and the detection tube 1.1 are both transparent hard plastic tubes. The inner diameter of the feed pipe 1.2 is 3 cm; the inner diameter of the detection tube 1.1 is 0.5 cm. The feed pipe 2 is a flexible tube with an inner diameter of 2 cm and a length of 4 m.

[0049] The installation and use method of this embodiment is as follows:

[0050] Fix the horizontal end of the feed pipe 1.2 in the mounting hole of the fixed plate 1, and insert the upper end of the feed pipe 2 into the upper end of the vertical section of the feed pipe 1.2; fix the horizontal end of the detection tube 1.1 in the detection hole of the fixed plate 1; adjust the length of the vertical support rod 3 according to the position of the core hole 6, insert the upper end of the vertical support rod 3 into the groove 7 at the bottom of the fixed plate 1, and tie and fix the lower part of the feed pipe 2 to the lower part of the vertical support rod 3; remove the floating slurry on the outside of the core hole 6 of the concrete component, and use the vertical support rod 3 to lift the fixed plate 1 with the adhesive protective film torn off to the height of the core hole 6, so that it is pasted on the beam component and completely covers the core hole 6, so that the mounting hole and the detection hole of the fixed plate 1 are connected with the core hole 6, and the pressing rod is used to press the pressing groove 8 on the outside of the fixed plate 1 to make the fixed plate 1 stick and fix.
