Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an anti-crack reinforcement installation device for ALC partition wall panel joints. Background Technology

[0002] Autoclaved aerated concrete (AAC) partition boards are porous lightweight wall panels made primarily of siliceous materials (quartz sand, fly ash, etc.) and calcareous materials (cement, lime), with aluminum powder added as a foaming agent. After batching, mixing, pouring, foaming, cutting, and molding, they are cured under high temperature and high pressure (180-200℃, 0.8-1.2MPa). When installing the partition boards, anti-crack reinforcement installation devices are required at the joints for secure installation.

[0003] Existing crack-resistant reinforcement installation devices typically involve splicing two partition boards together before installation. However, in actual use, these are usually fixed structures that cannot be flexibly adjusted according to the thickness of the ALC partition board or installation errors. This can easily lead to uneven stress on the joint due to positioning deviations, exacerbating the risk of cracking. Furthermore, the lack of adsorption and positioning on the surface of the ALC partition board during splicing makes the wall panel prone to displacement during construction, reducing the working efficiency of the crack-resistant reinforcement installation device.

[0004] Therefore, we urgently need to provide a crack-prevention and reinforcement installation device for the joints of ALC partition boards. Utility Model Content

[0005] The purpose of this utility model is to provide a crack-resistant reinforcement installation device for the joints of ALC partition boards, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-crack reinforcement installation device for ALC partition wall panel joints, comprising an installation plate and a partition wall panel. A grouting box is provided at the top of the installation plate, and the bottom of the grouting box is connected to the top of the installation plate. A flange is provided at the top of the grouting box, and the bottom of the flange is connected to the top of the grouting box. A dispersion plate is connected to the bottom of the grouting box, and the top of the dispersion plate is connected to the inner side of the installation plate. A fixing bolt is provided on the inner wall of the installation plate, and the outer wall of the fixing bolt is threadedly connected to the inner wall of the installation plate. One end of the fixing bolt is rotatably connected to one side of the reinforcement plate, and the other side of the reinforcement plate is connected to one end of a limiting rod. One side of the installation plate is connected to one end of a guide rod, and the outer wall of the guide rod is slidably connected to the inner wall of an adjusting plate. The inner wall of the adjusting plate is threadedly connected to the outer wall of the fixing bolt. One side of the adjusting plate is connected to one end of a connecting plate. The bottom of the connecting plate is connected to the top of a support plate, and the bottom of the support plate is connected to the top of an adsorption plate. The inner wall of the adsorption plate is threadedly connected to the outer wall of a threaded rod.

[0007] A further improvement is that the mounting plate is U-shaped, the dispersion plate is a steel plate with a thickness of 2-3mm, and grouting holes are opened at the bottom of the dispersion plate. The diameter of the grouting holes is 3-5mm, the spacing between the holes is 10-15mm, and the grouting holes are evenly distributed along the length of the dispersion plate.

[0008] A further improvement is that the adsorption plate is circular in shape, with a diameter of 50-80 mm. The end face of the adsorption plate facing the partition wall is provided with anti-slip texture, the depth of which is 1-2 mm. There are eight threaded rods, which are symmetrically distributed on the inner wall of the adsorption plate. The top of the partition wall is provided with an installation hole, and the bottom of the threaded rod is threaded to the inner wall of the installation hole.

[0009] A further improvement is that there are four guide rods, symmetrically distributed on both sides of the mounting plate, and an adjustment hole is opened on one side of each guide rod. One end of the fixing bolt is threaded to the inner wall of the adjustment hole.

[0010] A further improvement is that the reinforcing plate is made of galvanized steel sheet, the thickness of the reinforcing plate is 2-3mm, and it is attached to the side of the partition wall.

[0011] A further improvement is that the grouting box is made of transparent PVC material, with a wall thickness of 3-5mm and a volume of 1-2L. It has liquid level scale lines on its side with an accuracy of 50mL.

[0012] A further improvement is that the limiting rod is a cylindrical steel rod with a diameter of 6-8mm and a length of 40-60mm. There are two rods, which are symmetrically distributed on one side of the reinforcing plate. A fixing hole is opened on one side of the partition plate, and one end of the limiting rod is inserted into the inner wall of the fixing hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This ALC partition wall panel joint crack prevention and reinforcement installation device allows for flexible adjustment of the adjustment plate position based on the ALC partition wall panel thickness or installation error. An adjustment hole on one side of the guide rod, combined with fixing bolt two, quickly locks the adjustment plate, solving the problem of traditional fixing structures being unable to adapt to different wall panel specifications. Simultaneously, the overall structure of the U-shaped installation plate covers the entire width of the joint, avoiding uneven stress on the joint due to poor installation compatibility, reducing the risk of cracking from the source. The circular adsorption plate has deep anti-slip textures on the end face facing the partition wall panel, increasing friction with the wall panel surface. Furthermore, eight symmetrically distributed threaded rods can be inserted into the top installation hole of the partition wall panel, achieving rigid fixation between the adsorption plate and the wall panel. Combined with the limiting rod on one side of the reinforcement plate inserted into the fixing hole of the partition wall panel, a dual positioning of lateral limiting and longitudinal anchoring is formed. The side of the reinforcement plate fits tightly against the partition wall panel, and with the tightening force of fixing bolt one, a uniform clamping force is formed on both sides of the joint, thus better reinforcing the ALC partition wall panel joint to prevent cracking.

The inner wall of the adsorption plate 14 is threadedly connected to the outer wall of the threaded rod 15. The mounting plate 1 is U-shaped, the dispersion plate 5 is a steel plate with a thickness of 2-3mm, and the bottom of the dispersion plate 5 is provided with grouting holes with a diameter of 3-5mm and a spacing of 10-15mm. The grouting holes are evenly distributed along the length of the dispersion plate 5. The adsorption plate 14 is circular in shape and has a diameter of 50-80mm. Its end face facing the partition plate 2 is provided with anti-slip texture, the depth of which is 1-2mm. There are eight threaded rods 15, which are symmetrically distributed on the inner wall of the adsorption plate 14. The partition plate 2 has an installation hole at the top, and the bottom of the threaded rods 15 is threaded to the inner wall of the installation hole. There are four guide rods 9, symmetrically distributed on both sides of the mounting plate 1. An adjustment hole is opened on one side of the guide rod 9, and one end of the fixing bolt 11 is threaded to the inner wall of the adjustment hole. The reinforcing plate 7 is made of galvanized steel plate, and its thickness is 2-3mm. It is attached to the side of the partition wall 2.

A fixing hole is opened on one side of the partition wall plate 2, and one end of the limiting rod 8 is inserted into the inner wall of the fixing hole.

[0018] Grassroots handling requirements Before construction, the ground or substrate below the joints of ALC partition board 2 needs to be treated: the substrate must be flat, checked with a 2m straightedge, with a flatness deviation of ≤3mm. If there are protrusions, they need to be ground flat with an angle grinder; if there are depressions with a depth >5mm, they need to be leveled with 1:3 cement mortar and cured for 24 hours before installation. At the same time, a high-pressure blower with an air pressure ≥0.5MPa is needed to remove floating dust and debris from the surface and joints of partition board 2 to avoid affecting the adsorption force of adsorption board 14 and the mortar bonding effect.

[0019] Component inspection and tool preparation Component inspection: The coating thickness of the galvanized steel plate of the reinforcing plate 7 is confirmed to be ≥85μm using a coating thickness gauge, and there is no rust or deformation; the anti-slip texture of the adsorption plate 14 should be free of wear and the depth should be maintained at 1-2mm, measured with a depth gauge; the grouting box 3 is free of cracks and the liquid level scale is clear; the straightness deviation of the cylindrical steel rod of the limit rod 8 is ≤1mm / m to avoid jamming when inserted into the fixing hole.

[0020] Tools required: A torque wrench with a range of 0-50 N·m, an electric drill with φ6-φ10 drill bits, a level with an accuracy of ±0.5 mm / m, an ultrasonic tester with a frequency of 50 kHz for later grouting fullness testing, and a manual grouting device with a grouting box, 3 flanges, and 4 interfaces.

[0021] When rotating the fixing bolt -6 specification M10, a torque wrench should be used to control the tightening torque to 15-20 N·m: If the torque is too small, the reinforcing plate 7 and the partition wall plate 2 will not fit tightly with a gap >0.5mm, and an effective clamping will not be formed; if the torque is too large, the porous structure on the surface of the ALC partition wall plate will be easily damaged.

[0022] After the reinforcing plate 7 is attached to the side of the partition wall 2, the gap should be checked with a feeler gauge: a gap ≤ 0.5mm is acceptable; if the gap > 0.5mm, the fixing bolt 1 should be loosened, a 1-2mm thick barley paper pad should be pasted on the inside of the reinforcing plate, and then tightened to the specified torque.

[0023] Using the center line of the ALC partition wall panel joint as a reference, mark the center line with a laser line projector, and adjust the position of adjustment plate 10: 100mm thick wall panel: The inner edge of the adjustment plate 10 must be aligned with the center line to ensure that the adsorption plate 14 can cover the top 1 / 2 width of the wall panel (50mm). 200mm thick wall panel: The inner edge of the adjustment plate 10 should be offset from the center line by 5mm and face the outside of the wall panel to avoid interference between the adsorption plate 14 and the joint.

[0024] After adjustment, tighten the fixing bolts 11 (M8 specification) with a torque of 12-15 N·m. At the same time, use a level to check the levelness of the adjustment plate 10: the horizontal deviation should be ≤1 mm / m to prevent uneven force on the adsorption plate 14 from causing the wall panel to tilt.

[0025] After the threaded rod 15 is inserted into the top mounting hole of the partition wall 2, it needs to be tightened in two steps: First, tighten it until the bottom of the threaded rod contacts the bottom of the hole and the resistance increases. Second, tighten it for another 2 turns to ensure that the thread engagement depth is ≥5mm.

[0026] After the adsorption plate 14 is fixed, two verifications need to be performed: Adsorption force verification: Hook the side of the adsorption plate 14 with a spring scale and pull it horizontally to 100N. The adsorption plate does not move, indicating that the adsorption force is qualified. The anti-slip texture + threaded rod double fixation is effective. Verticality verification: Use a laser line projector to check the verticality of partition wall panel 2: the deviation is ≤2mm / 2m. If the deviation exceeds the standard, the threaded rod 15 needs to be loosened, the position of the adsorption plate 14 needs to be finely adjusted, and then it needs to be fixed again.

[0027] During grouting, a manual grouting device should be used to slowly inject grout from the top of flange 4. The grouting speed should be controlled at 50-100mL / min. If the speed is too fast, air bubbles will easily be generated in the joint. If the air bubble rate is >5%, cracking will be easy in the later stage. If the speed is too slow, the mortar will easily set in the grouting box.

[0028] Criteria for judging whether the joint is filled: ① If the liquid level scale of grouting tank 3 remains stable for 30 seconds without dropping, it means there are no gaps in the joint; ② If mortar overflows evenly from the top surface of the wall panel at the top of the joint, with an overflow width ≥10mm, stop grouting at this time, and use a scraper to smooth the overflowing mortar until it is flush with the top surface of the wall panel.

[0029] During the 24-hour static curing stage, the following environmental conditions must be met to ensure that the mortar strength meets the standard: compressive strength ≥ 15 MPa after 24 hours: Ambient temperature: 5-35℃; if the temperature is <5℃, an electric heating blanket with a temperature setting of 50℃ should be placed over the outside of the joint to maintain the temperature and extend the curing time to 48 hours. Ambient humidity: ≤80%; if humidity >80%, place 500g of quicklime desiccant per square meter around the installation plate 1 to prevent sand from rising from the mortar surface; Avoid vibration: During the curing period, avoid knocking, moving or other vibration operations near the partition wall to prevent the mortar in the joint from separating from the wall panel.

[0030] The detachable grouting box 3, adsorption plate 14, and adjusting plate 10 must be handled promptly after removal. Grouting box 3: Rinse the inside with clean water to remove residual mortar. The rinsing pressure should be ≥0.3MPa. After drying, apply Vaseline to the flange 4 interface to prevent rust. Adsorption plate 14: Use a wire brush to clean the mortar debris in the anti-slip pattern. If the depth of the anti-slip pattern is <1mm, a new adsorption plate needs to be replaced to avoid insufficient adsorption force in the future. Threaded rod 15: Sand off any remaining mortar on the surface, apply rust-preventive oil (model 20 machine oil), and store separately.

[0031] Non-removable component mounting plate 1 and guide rod 9: If they need to be retained as base reinforcement components, they should be coated with epoxy zinc-rich primer with a thickness of 60μm to prevent rusting over long-term use; if they need to be removed, they should be slowly pried from the bottom of the mounting plate with a pry bar to avoid damaging the wall panel base.

[0032] Joint flatness: Use a 2m straightedge to press against the surface of the wall panels on both sides of the joint, and measure the flatness deviation to be ≤2mm; Grouting fullness: Use an ultrasonic tester at a frequency of 50kHz to test one point every 500mm along the joint length. Grouting fullness ≥95% with no obvious void reflection signal; Reinforcement strength: Apply a horizontal thrust of 500N to the top of the partition wall panel for 30s. If there is no displacement at the joint, the displacement measured with a dial indicator should be ≤0.1mm. Component stability: Check the torque of fixing bolts one and two: the torque of fixing bolt one should remain at 15-20 N·m, and the torque of fixing bolt two should remain at 12-15 N·m, with no looseness.

[0033] Working Principle: When two ALC partition panels need to be joined, the operator places the mounting plate 1 on the ground or base layer below the joint of the partition panel 2. Then, the fixing bolt 6 is rotated to move it along the inner wall of the mounting plate 1. This movement of the fixing bolt 6 moves the reinforcing plate 7, allowing it to fit against one side of the two partition panels 2 and clamp them in place. At this point, the limiting rod 8 can be inserted into the fixing hole on one side of the partition panel 2, thus initially positioning and fixing the two partition panels 2, ensuring that the center line of the mounting plate 1 is aligned with the joint. Next, the fixing bolt 11 is rotated to move it along the inner wall of the adjusting plate 10. This movement of the fixing bolt 11 allows it to be pulled out from one side of the guide rod 9, thus releasing the limiting fixation of the adjusting plate 10. Pulling the suction plate 14 then indirectly causes the adjusting plate 10 to slide on the guide rod 9, allowing for quick and convenient adjustment of the position of the adjusting plate 10, thereby achieving better positioning. Different sized partition wall panels 2 are fixed in place. After adjustment, the threaded rod 15 is rotated to move it on the inner wall of the adsorption plate 14. The threaded rod 15 can be inserted into the mounting hole on the top of the partition wall panel 2, thereby fixing the adsorption plate 14 and the partition wall panel 2. This forms a longitudinal pressing and lateral limiting on both sides of the joint, further tightening and aligning the two partition wall panels 2 for better use. At this time, mortar is injected into the grouting box 3. The mortar fills the joint evenly through the grouting hole of the dispersion plate 5. The liquid level scale of the grouting box 3 is observed to ensure that the mortar fills the joint. After standing for 2-3 hours (when the mortar has initially set), the fixing bolt 6 is rotated to move the reinforcing plate 7 away from the partition wall panel 2. At the same time, the grouting box 3 and the adsorption plate 14 are removed. After the mortar has completely cured (24 hours), the mounting plate 1 can be removed (for reuse) or retained as a base reinforcement component as needed.
