Description

Technical Field

[0001] The present invention belongs to the field of grouting devices for ALC (autoclaved aerated concrete) load-bearing wall panel connection nodes in ALC slab assembly structural systems, and in particular to a dynamic pressure-regulated grouting device and method based on grouting fullness feedback. Background Art

[0002] ALC wall panels are made from fly ash (or silica sand), cement, and lime, and are cured with high-pressure steam to form porous concrete panels (including treated steel reinforcement). ALC wall panels can be used as both load-bearing wall materials and roof panels, and are a new building material with superior performance.

[0003] In existing ALC slab prefabricated structures, grout is poured into the holes between two adjacent ALC load-bearing plates through manual grouting, relying on shaking the steel bars in the holes to assist in the flow of the grout. This method makes it difficult to ensure that the grout at the bottom of the hole is completely filled, and cavities are easily formed. In addition, the repeated shaking of the steel bars during the upper grouting process will seriously disturb the slurry that has initially solidified below. This operation is also not conducive to the precise positioning and fixation of the steel bars, and significantly weakens the bond between the steel bars and the hardened slurry. The cavities, positioning deviations, and insufficient bond strength caused by this operation will damage the integrity and load-bearing performance of the prefabricated structure connection nodes, posing a hidden danger to structural safety. Therefore, a dynamic pressure-regulated grouting device based on grouting fullness feedback is urgently needed to solve the above problems. Summary of the Invention

[0043] A method for using a dynamic pressure-regulated grouting device based on grouting fullness feedback, the method comprising the following steps:

[0044] S1: Pass the steel bar 5 through the two supporting half-ring units 1-1 and rotate the screw 2-1 to clamp the steel bar 5;

[0045] S2: Loosen the top screw 1-3-5 and pull the slide 1-3-3 to move so that the rotating ball 1-3-4 rests against the inner wall of the hole between the ALC load-bearing plates;

[0046] S3: Screw the connector 4-3 into the grouting pipe 1-1-2 to connect the feed pipe 4-1 with the grouting machine outlet;

[0047] S4: Turn on the grouting machine to start grouting.

[0048] The working principle of the present invention is:

[0049] This device is connected to an external power supply to power the vibrator 2-5. When using this device, the steel bar 5 is passed through the two supporting half-ring units 1-1, and then the screw 2-1 is rotated to drive the arc plate 1-2 to move and clamp the steel bar 5. The rotating ball 2-3 can reduce the friction with the steel bar 5, and then the top screw 1-3-5 is loosened and the slide 1-3-3 is pulled to move so that the rotating ball 1-3-4 is pressed against the inner wall of the hole between the ALC load-bearing plate structure 6, and then the top screw 1-3-5 is tightened to fix the slide 1-3-3, and the connector 4-3 is screwed into the grouting pipe 1- 1-2, then the feed pipe 4-1 is fixedly connected to the discharge port of the grouting machine (external technology adopts external purchase), and then a long stick or steel bar is used to push the supporting half-ring unit 1-1 downward along the steel bar 5 until the device moves to the bottom of the hole between the ALC load-bearing plate structure 6, and then the grouting machine is powered on to extract the slurry through the feed pipe 4-1, the feed pipe 4-2 and the connector 4-3 into the grouting pipe 1-1-2, and the slurry is then sprayed out into the hole between the ALC load-bearing plate structure 6 through the grouting pipe 1-1-2, and at the same time, the feed pipe 4-1 is pulled upward through the feed pipe 4-2 and the connector 4 -3 drives the supporting semi-ring unit 1-1 to move upward along the steel bar 5, thereby realizing layer-by-layer grouting in the holes between the ALC load-bearing plate structure 6, which can avoid the formation of cavities between the slurries. At the same time, the vibrator 2-5 is energized to generate vibration, and the vibration is transmitted to the steel bar 5 through the arc plate 1 2-2 and the rotating ball 2-3, so that the steel bar 5 vibrates and the slurry can be vibrated, further increasing the density between the slurries to avoid the formation of cavities. The arc plate 1 2-2 is set to clamp steel bars of different diameters. At the same time, by adjusting the moving unit 1-3, it can be suitable for different models and sizes. The ALC load-bearing plate structure 6 is clamped by two clamping devices 2 on the steel bars 5, so that the steel bars 5 can always be in the center position of the hole between the ALC load-bearing plate structures 6, which can solve the problem that the longer the steel bars are, the stronger their bending properties are, and the steel bars are easy to lean on the inner wall of the hole. After the grouting is completed, the tilted steel bars will also affect the stability and safety between the ALC load-bearing plate structures. When the supporting semi-ring unit 1-1 moves to the upper end of the ALC load-bearing plate structure hole to complete the grouting, the grouting machine is turned off, and then the above steps are reversed to remove the device for grouting of the next hole.

[0050] When grouting the ALC load-bearing plate structure 6 set at a 90° angle, remove the fixing bolt 2 on the fixing block 1-1-7, then rotate one of the half rings 1-1-1 through the hinge 1-2, fold it over the other half ring 1-1-1, and then pass the fixing bolt 1 through the fixing hole 1-1-3 set on the two half rings 1-1-1 to fix the two folded half rings 1-1-1. At the same time, the grouting pipes 1-1-2 set on the two folded half rings 1-1-1 are pressed against each other, and two of the connecting heads 4-3 are screwed into the grouting pipe 1-1-2 at the upper end. During grouting, the slurry enters the grouting pipe 1-1-2 at the upper end through the grouting pipe 1-1-2 at the lower end and then sprays out to complete the grouting. Then, the moving unit 1-3 is pressed against the inner wall of the side hole of one of the ALC load-bearing plate structures 6. Then, the spring telescopic rod 1-1-5 is extended to drive the guide wheel 1-1-6 to press against the side wall of another ALC load-bearing plate structure 6, and the screw 2-1 set in the clamping device 2 is rotated to make the arc plate 1 2-2 press against the steel bar 5, so that the steel bar 5 is in a vertical state, and then the arc plate 2 3-1 is pressed against the other side of the steel bar, and the top screw 2-6 is unscrewed to make the long hole rod 3-3 be laid on the arc plate 1 2-2, and then the top screw 2-6 is passed through the long hole rod 3-3 and screwed into the arc plate 1 2-2 to reset it, and the long hole rod 3-3 is limited and fixed, thereby achieving support for the steel bar 5, and then the half ring 1-1-1 is pushed into the bottom of the hole of the ALC load-bearing plate structure 6, and then the above grouting steps are repeated to grout the hole. After grouting is completed, the above steps are reversed to reset the half ring 1-1-1.

[0051] At the same time, the grouting pressure and flow rate can be adjusted by adjusting the pressure of the grouting machine to ensure uniformity and stability during the grouting process.

[0052] At the same time, when grouting the ALC load-bearing plate structure 6, the fixed pulley can be fixed on the side of the ALC load-bearing plate structure 6 by gluing or bolting, so that the feed pipe 4-1 is placed on the fixed pulley, which can reduce the friction of the feed pipe 4-1 on the ALC load-bearing plate structure 6, thereby avoiding damage to the feed pipe 4-1 or the ALC load-bearing plate structure 6. Pulling the feed pipe 4-1 at a uniform speed can further increase the fullness of the grouting; further, the slide 1-3-3 and the rotating ball 1-3-4 can be replaced by a guide wheel driven by a driving motor, which is pressed against the inner wall of the hole of the ALC load-bearing plate structure 6 through the guide wheel, and is driven by the driving motor to rotate and drive the device to move upward along the hole, which can replace the method of manually pulling the feed pipe 4-1 to drive the device to move, and can further increase the stability of the device and the fullness of the grouting.
