DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a crack reinforcement and repair device for construction management of civil engineering includes a beam body 1 and a floor slab 2. The beam body 1 is integrally connected to the floor slab 2. A crack 11 is opened on the beam body 1. A bottom support 3 is provided at the bottom of the beam body 1. A supporting mechanism 4 is provided at the bottom of the bottom support 3. A clamping mechanism 5 is provided on the top of the bottom support 3. The clamping mechanism 5 clamps both sides of the beam body 1. A pressing mechanism 6 is also passed through the bottom support 3. A positioning frame 7 is detachably connected to the side of the crack 11. A grouting mechanism 8 is provided on the positioning frame 7. A sealing mechanism 9 is provided on the outside of the grouting mechanism 8.

[0025] The support mechanism 4 is used for temporary support before reinforcement and repair. When the crack 11 problem is found, the support mechanism 4 is used for temporary reinforcement first to prevent the crack 11 from further developing. The support mechanism 4 includes a support rod 41 and a positioning groove 42. The positioning groove 42 is provided in the middle of the bottom of the base 3. The top of the support rod 41 supports the positioning groove 42. The bottom of the support rod 41 contacts the ground. After the crack 11 is found, the base 3 is supported on the bottom of the beam body 1, and the top of the support rod 41 is pushed into the positioning groove 42. The support rod 41 adopts a buckle frame rod, and the support rod 41 can be retracted, so that the support rod 41 can hold the bottom of the beam body 1 tightly to prevent the crack 11 from continuing to develop.

[0026] Before repairing the crack 11 , the clamping mechanism 5 and the pressing mechanism 6 are installed in place so that the clamping mechanism 5 and the pressing mechanism 6 replace the supporting mechanism 4 to prevent the supporting rod 41 from hindering the movement of personnel and equipment.

[0027] like Figure 2 As shown, there are two groups of clamping mechanisms 5, and the clamping mechanisms 5 are arranged on both sides of the beam body 1. The clamping mechanisms 5 include positioning plates 51, sliding plates 52 and pushing rods 53. The positioning plates 51 are fixed to the top of the base 3. The distance between the two positioning plates 51 is greater than the width of the beam body 1. The sliding plates 52 are slidably connected to the top of the base 3. The top of the base 3 is provided with a slide groove 31, and the bottom of the sliding plate 52 is provided with a slider 521. The slider 521 is slidably connected to the slide groove 31. The middle part of the pushing rod 53 is screwed to the positioning plate 51, and the top of the pushing rod 53 is rotatably connected to the side wall of the sliding plate 52. By rotating the pushing rod 53, the pushing rod 53 is moved back and forth relative to the positioning plate 51, and the front end of the pushing rod 53 drives the sliding plate 52 to move back and forth, so that the two sliding plates 52 can clamp the two sides of the beam body 1 to position the side walls of the beam body 1 and the base 3.

[0028] The clamping mechanism 6 includes a screw 61 and a fastening button 62. The screw 61 passes through the base support 3. The top of the screw 61 is fixedly connected to the floor slab 2 by means of embedded reinforcement. After the crack 11 is repaired, the screw 61 can be cut. The fastening button 62 is screwed to the screw 61. The fastening button 62 fits with the bottom of the base support 3 and pushes the base support 3 to reinforce the bottom of the beam 1. When the fastening button 62 lifts the base, the support rod 41 can be withdrawn. At this time, the base support 3 can also press the beam 1 to reduce the development of the crack 11.

[0029] The positioning frame 7 is made of a flexible material, which can be optionally made of rubber. The positioning frame 7 is bonded to the periphery of the crack 11, and the positioning frame 7 is attached along the development direction of the crack 11. A through hole 71 is provided in the middle of the positioning frame 7, and the crack 11 is provided in the through hole 71. Two raised strips 72 are provided on the side wall of the positioning frame 7. The positioning frame 7 is used to remind the repair personnel of the position of the crack 11 and speed up the repair. If the trend of the crack 11 is too complicated and pasting the positioning frame 7 is too time-consuming, the step of pasting the positioning frame 7 can be cancelled.

[0030] like Figure 3 、Figure 4 As shown, the grouting mechanism 8 is used to repair the crack 11. The grouting mechanism 8 includes a moving block 81, an air blowing pipe 82 and a grouting pipe 83. The repairer holds the moving block 81 and moves it. The moving block 81 slides along the raised strip 72. The raised strip 72 shows the trajectory of the crack 11. The air blowing pipe 82 and the grouting pipe 83 are detachably connected to the moving block 81. The front ends of the air blowing pipe 82 and the grouting pipe 83 face the crack 11. The air blowing pipe 82 blows out high-pressure gas to blow out impurities in the crack 11. The grouting pipe 83 injects the repair liquid into the crack 11 through the grouting pipe 83 at high pressure, so that the upper and lower concrete sides are connected as one.

[0031] The side wall of the grouting pipe 83 is provided with a thread, and the grouting pipe 83 is screwed to the moving block 81. The grouting pipe 83 can move forward and backward relative to the moving block 81. Moving the grouting pipe 83 forward and backward can make the head of the grouting pipe 83 close to the crack 11, so that the repair liquid can be injected into the crack 11, reducing waste.

[0032] The sealing mechanism 9 includes a sealing strip 91, a winding roll 92, a roller 93 and a connecting rod 94. The winding roll 92 is arranged on the side wall of the moving block 81. One end of the sealing strip 91 is wound around the winding roll 92, and the other end of the sealing strip 91 is attached to the crack 11. When the moving block 81 moves, the sealing strip 91 is rotated out from the winding roll 92. One end of the connecting rod 94 is connected to the roller 93, and the other end of the connecting rod 94 is rotated to connect to the moving block 81. The roller 93 presses the sealing strip 91 so that the sealing strip 91 is attached to the crack 11, thereby preventing the repair liquid injected into the crack 11 from flowing out and affecting the repair effect.

[0033] A reaction plate 811 is provided on the moving block 81, and a spring 812 is fixed to the reaction plate 811. The other end of the spring 812 is connected to the connecting rod 94. The spring 812 is in a contracted state. The spring 812 always exerts pressure on the connecting rod 94 in the direction of the crack 11. The spring 812 pushes the connecting rod 94 and the roller 93 to apply pressure in the direction of the crack 11, so that the sealing strip 91 can be firmly attached to the crack 11.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
