Description

Technical Field

[0001] This utility model belongs to the technical field of autoclaved aerated concrete (AAC) panel installation, specifically relating to an elevation adjustment device for installing AAC panels. Background Technology

[0002] In recent years, autoclaved aerated concrete (AAC) panels have been widely used in multi-story and high-rise buildings for their superior properties, including lightweight, high strength, fire resistance, sound insulation, and thermal insulation, as well as their industrialized, standardized, and prefabricated construction characteristics. However, many technical challenges still exist in the actual installation process of AAC panels.

[0003] After installation, autoclaved aerated concrete (AAC) panels require temporary supports and alignment tools for positioning and fixation. Specifically, existing technologies typically use wooden wedges as temporary supports. Operators must repeatedly tap the wedges to adjust their insertion depth into the bottom of the AAC panel, thereby adjusting the panel's elevation. However, existing technologies have the following drawbacks: ① When using wooden wedges for elevation adjustment, to prevent excessive insertion and elevation loss, 3-4 operators are usually required to work together slowly, increasing labor costs and reducing overall construction efficiency; ② The height of the wooden wedges is limited, and when encountering uneven ground, their adjustment capacity often fails to meet actual needs, preventing the achievement of the maximum elevation adjustment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an elevation adjustment device for the installation of autoclaved lightweight aerated concrete panels, which can improve construction efficiency, reduce labor costs, and ensure installation quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An elevation adjustment device for installing autoclaved lightweight aerated concrete (AAC) panels includes:

[0007] The support assembly includes a base plate, two upright plates facing each other on the upper surface of the base plate, a crossbar connecting the two upright plates, and a vertical bar disposed on the upper surface of the base plate, wherein the vertical bar is a predetermined distance from the crossbar.

[0008] An adjusting plate assembly includes a pressure plate, a connecting plate, and a lifting plate. The pressure plate and the lifting plate are arranged parallel to each other and staggered front to back. One end of the connecting plate is connected to the end of the pressure plate near the lifting plate, and the other end of the connecting plate is connected to the end of the lifting plate near the pressure plate. The pressure plate rests on the crossbar and has a strip-shaped hole. The upper end of the vertical rod passes through the strip-shaped hole, and an adjustable limiting unit for limiting the position of the pressure plate is connected to the vertical rod.

[0009] Furthermore, the adjustable limiting unit is a nut, and the outer cylindrical surface of the vertical rod is provided with a thread that mates with the nut, and the nut is threadedly connected to the vertical rod.

[0010] Furthermore, the upper surface of the lifting plate is provided with a sloping surface.

[0011] Furthermore, the support assembly also includes a first wedge block and a second wedge block, the large ends of the first wedge block and the second wedge block being respectively connected to both sides of one end of the base plate, and a space capable of accommodating the lifting plate is formed between the first wedge block and the second wedge block.

[0012] Furthermore, the slope of the wedge surface of the first wedge block and the second wedge block is not greater than the slope of the slope surface.

[0013] Furthermore, the crossbar is a cylindrical bar.

[0014] Furthermore, the distance from the end of the pressure plate near the lifting plate to the crossbar is no greater than one-third of the length of the pressure plate.

[0015] Furthermore, the angle between the connecting plate and the horizontal plane is 45°~60°.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] This utility model provides an elevation adjustment device for installing autoclaved aerated concrete (AAC) panels. In use, elevation adjustment devices are symmetrically arranged on both sides of the AAC panel. The bottom of the AAC panel rests on the lifting plate of each elevation adjustment device, ensuring full contact. Next, downward pressure is applied to the end of the pressure plate furthest from the connecting plate. The pressure plate rotates around the crossbar, causing the other end to move upwards, which in turn lifts the lifting plate upwards via the connecting plate. Once the elevation of the AAC panel is adjusted to the set position, an adjustable limit unit limits the pressure plate, ensuring the AAC panel remains at the set elevation. Compared to traditional methods using wooden wedges for elevation adjustment, which require 3-4 operators and are slow, this utility model allows only two people to complete the elevation adjustment of the AAC panel, reducing labor costs, improving construction efficiency, and shortening the construction period. The elevation adjustment device uses an adjustable limit unit to limit the pressure plate, ensuring that the autoclaved aerated concrete (AAC) slab can be stably maintained in the set position after elevation adjustment, avoiding the elevation control problem caused by improper adjustment of wooden wedges in traditional methods. Traditional wooden wedge adjustment methods have limited adjustment capabilities when dealing with uneven ground, often failing to meet actual needs. However, the elevation adjustment device of this invention achieves flexible and variable height adjustment range through the up-and-down rotation of the pressure plate around the crossbar, enabling the device to cope with uneven ground and exhibiting strong ground adaptability.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Combination Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an elevation adjustment device for installing autoclaved aerated concrete (AAC) panels, mainly to solve the problems of high labor costs, low construction efficiency, and insufficient adjustment capacity when using wooden wedges for elevation adjustment in the prior art. The elevation adjustment device mainly includes a support assembly 1 and an adjustment plate assembly 2, as well as an adjustable limiting unit 3 for restricting the movement of the adjustment plate assembly 2. The support assembly 1 includes a base plate 11, upright plates 12 facing each other on both sides of the upper surface of the base plate 11, a horizontal bar 13 connecting the two upright plates 12, and a vertical bar 14 set on the upper surface of the base plate 11, with the vertical bar 14 at a set distance from the horizontal bar 13. The adjusting plate assembly 2 includes a pressure plate 21, a connecting plate 22, and a lifting plate 23. The pressure plate 21 and the lifting plate 23 are arranged in parallel and staggered front to back. One end of the connecting plate 22 is connected to the end of the pressure plate 21 near the lifting plate 23, and the other end of the connecting plate 22 is connected to the end of the lifting plate 23 near the pressure plate 21. The pressure plate 21 is mounted on the crossbar 13. A strip hole 24 is provided on the pressure plate 21. The upper end of the vertical rod 14 passes through the strip hole 24. An adjustable limiting unit 3 for limiting the position of the pressure plate 21 is connected to the vertical rod 14.

[0027] Specifically, the base plate 11, as the fundamental support component of the entire device, is made of metal plate. Vertical plates 12 are positioned opposite each other on the upper surface of the base plate 11, supporting the horizontal bar 13 and providing installation space for the adjusting plate assembly 2. The horizontal bar 13 connects the two vertical plates 12, forming the support point for the pressure plate 21. It should be noted that the horizontal bar 13 should ensure that the pressure plate 21 will not deform or be damaged due to excessive force during rotation. A vertical bar 14 is positioned on the upper surface of the base plate 11 at a predetermined distance from the horizontal bar 13, passing through the slotted hole 24 on the pressure plate 21, and serving as the mounting base for the adjustable limiting unit 3. The pressure plate 21 rests on the horizontal bar 13, with a slotted hole 24 at one end for the vertical bar 14 to pass through, allowing the pressure plate 21 to slide and rotate on the vertical bar 14. A connecting plate 22 connects the pressure plate 21 and the lifting plate 23, transmitting the rotational movement of the pressure plate 21 to the lifting plate 23. The lifting plate 23 is arranged parallel to and staggered with the pressure plate 21 to support the bottom of the autoclaved aerated concrete (AAC) slab. An adjustable limiting unit 3 is installed on the vertical rod 14 to limit the pressure plate 21, ensuring that the AAC slab remains in the set position after elevation adjustment. For example, the adjustable limiting unit 3 can be a threaded sleeve, a lock nut, or similar structure, and the limiting of the pressure plate 21 is achieved by rotating and adjusting the position of the lock nut.

[0028] like Figure 4 As shown, during the installation of the autoclaved aerated concrete (AAC) panel 4, elevation adjustment devices are symmetrically arranged on both sides of the AAC panel 4. The bottom of the AAC panel 4 is placed on the lifting plate 23 of each elevation adjustment device, ensuring full contact with the lifting plate 23. Next, downward pressure is applied to the end of the pressure plate 21 away from the connecting plate 22. The pressure plate 21 rotates around the crossbar 13, causing the other end to move upward, and driving the lifting plate 23 upward through the connecting plate 22. After the elevation of the AAC panel 4 is adjusted to the set position, the adjustable limit unit 3 is used to limit the pressure plate 21, ensuring that the AAC panel 4 is maintained at the set elevation.

[0029] When using the elevation adjustment device of this invention to adjust the elevation of autoclaved lightweight aerated concrete (AAC) slab 4, only two people are needed to complete the work, reducing labor costs and improving construction efficiency compared to traditional methods. The adjustable limiting unit 3 limits the pressure plate 21, ensuring that the AAC slab 4 remains in the set position after elevation adjustment, thus improving installation quality. Since the pressure plate 21 can rotate up and down around the crossbar 13, its height adjustment range is variable, therefore it is not affected by uneven ground and has strong adaptability.

[0030] In one possible implementation, the adjustable limiting unit 3 is a nut, and the outer cylindrical surface of the vertical rod 14 is provided with a thread that mates with the nut, and the nut is threadedly connected to the vertical rod 14.

[0031] Specifically, the outer cylindrical surface of the vertical rod 14 is threaded to match the nut. This thread not only ensures the nut can move up and down along the vertical rod 14 but also provides a self-locking function between the nut and the vertical rod 14, guaranteeing the accuracy of elevation adjustment and stability after adjustment. Before installing the autoclaved aerated concrete (AAC) panel, the elevation adjustment device must first be placed in the predetermined position, and the nut tightened to the appropriate position on the vertical rod 14 to provide sufficient adjustment space during subsequent elevation adjustments. After the AAC panel is placed on the lifting plate 23, the operator can adjust its height by applying downward pressure to the pressure plate 21. During adjustment, the operator should monitor the elevation changes of the AAC panel and tighten the nut as needed to limit further movement of the pressure plate 21. Specifically, when it is necessary to adjust the pressure plate 21 downwards, the operator simply needs to tighten the nut downwards along the vertical rod 14. Because the threaded connection between the nut and the vertical rod 14 has a self-locking function, once the appropriate position is reached, the nut will automatically lock onto the vertical rod 14, thus simultaneously limiting the position of the pressure plate 21.

[0032] like Figure 2 As shown, in one possible implementation, the upper surface of the lifting plate 23 is provided with a ramp surface 231.

[0033] Specifically, the upper surface of the lifting plate 23 is designed as a slope 231, meaning the lifting plate 23 itself has a wedge-shaped structure. It should be noted that the inclination angle and length of the slope 231 can be adjusted according to actual needs to meet the elevation adjustment requirements in different scenarios. The design of the slope 231 expands the vertical adjustment range of the lifting plate 23. When the autoclaved aerated concrete (AAC) panel is placed on the lifting plate 23, its bottom will contact the slope 231. By adjusting the position and angle of the pressure plate 21, operators can achieve small or large vertical adjustments to the AAC panel, thereby meeting more precise elevation requirements. The slope 231 also enhances the adaptability of the elevation adjustment device to different ground conditions. When there are slight unevenness or inclinations on the ground, the slope 231 of the lifting plate 23 can effectively compensate for these differences, ensuring that the AAC panel can be stably installed in the predetermined position.

[0034] In one possible implementation, such as Figures 1 to 3 As shown, the support assembly 1 also includes a first wedge block 15 and a second wedge block 16. The large ends of the first wedge block 15 and the second wedge block 16 are respectively connected to the two sides of one end of the base plate 11, and a space is formed between the first wedge block 15 and the second wedge block 16 that can accommodate the lifting plate 23.

[0035] In other words, the first wedge 15 and the second wedge 16 are respectively connected to both sides of one end of the base plate 11, with their large ends close to each other, forming a space that can accommodate the lifting plate 23. The design of the first wedge 15 and the second wedge 16 allows the lifting plate 23 to be placed more stably between them. The presence of the first wedge 15 and the second wedge 16 also enhances the overall stability of the elevation adjustment device, preventing shaking or tilting during installation.

[0036] Preferably, the slope of the wedge surface of the first wedge block 15 and the second wedge block 16 is not greater than the slope of the slope surface 231, ensuring that when the lifting plate 23 is placed between the wedge blocks, its slope surface 231 can form an effective contact area with the bottom of the autoclaved lightweight aerated concrete slab, thus avoiding poor contact.

[0037] Ideally, the slope of the wedge block should be consistent with or similar to that of the lifting plate slope to minimize the lateral forces caused by slope differences, thereby enhancing the device's anti-overturning capability.

[0038] In one possible implementation, the crossbar 13 is a cylindrical bar, meaning its cross-section is circular, making its surface smooth without sharp edges or protrusions, thereby reducing friction and wear between it and the pressure plate 21. The smooth surface of the cylindrical bar allows the pressure plate 21 to rotate around it more easily, making the adjustment process smoother.

[0039] In one possible implementation, the distance from the end of the pressure plate 21 near the lifting plate 23 to the crossbar 13 is no greater than one-third of the length of the pressure plate 21. Specifically, the longer the lever arm, the smaller the force required. This design ensures that the pressure plate 21 has a sufficient lever arm when applying pressure, thereby making it easier to adjust the elevation of the autoclaved lightweight aerated concrete slab via the lifting plate 23, and allowing the operator to apply pressure more easily when adjusting the elevation.

[0040] In one possible implementation, the angle between the connecting plate 22 and the horizontal plane is 45° to 60°. When the angle of the connecting plate 22 is within this range, the load can be transferred and distributed more effectively, reducing stress concentration and deformation, which helps ensure the stability of the elevation adjustment device when bearing the load of autoclaved aerated concrete slabs. It also enhances the reliability of the connection between the pressure plate 21 and the lifting plate 23.

[0041] In one embodiment, the pressure plate 21, connecting plate 22, and lifting plate 23 are composed of 10mm thick metal sheets with a planar projection length of 195mm. The base plate 11 is a 10mm thick U-shaped base plate with a length of 195mm and a width of 80mm. Two upright plates 12 are symmetrically welded and fixed to the base plate using 10mm thick trapezoidal plates, and the crossbar 13 is fixed by welding with Ø10 steel bars. The adjustable limiting unit 3 uses an M10 nut, and the vertical rod 14 uses a screw, which is welded and fixed to the base plate 11 perpendicularly. It is used for the up-and-down movement of the nut and uses an Ø10 screw, with a maximum screw travel of approximately 90mm.
