Description

Technical Field

[0001] This utility model relates to the field of ALC board installation technology, specifically to an L-shaped ALC board and a T-shaped ALC board installation structure. Background Technology

[0002] ALC board is short for autoclaved lightweight concrete board. In the current technology, when installing L-shaped ALC boards and T-shaped ALC boards, special adhesive is used for bonding. This process will result in large cracks at the joints within a month after construction. In addition, after delivery, due to building settlement and other reasons, cracks will gradually appear at the joints of L-shaped ALC boards and T-shaped ALC boards, and the risk of cracking is relatively high.

[0003] Traditional building partitions often use materials such as brick masonry, aerated concrete blocks, or light steel keel gypsum board. These materials have problems such as heavy weight, low construction efficiency, poor sound and heat insulation performance, and easy cracking. Brick masonry walls need to be built on-site, and the construction period is long. Light steel keel gypsum board partitions have disadvantages such as low strength, insufficient fire resistance, and easy cracking of joints. Aerated concrete blocks rely on mortar bonding and are easily affected by humid environments, which can lead to wall deformation or detachment.

[0004] Traditional ALC panel installation relies heavily on mortar bonding or spot welding, which results in slow construction speed, low connection strength, and easy loosening. The joint treatment of irregular nodes such as L-shaped and T-shaped nodes is difficult, and traditional processes require on-site cutting and patching, which leads to a decrease in waterproof and fireproof performance and poor appearance. Ordinary installation structures are prone to cracking during earthquakes or temperature changes, affecting the stability and service life of the wall. Therefore, there is an urgent need for an L-shaped ALC panel and T-shaped ALC panel installation structure. Utility Model Content

[0005] The purpose of this utility model is to provide an L-shaped ALC board and a T-shaped ALC board mounting structure to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an L-shaped ALC plate and a T-shaped ALC plate installation structure, including a T-shaped ALC plate, a drainage groove on the lower surface of the T-shaped ALC plate, a connecting block fixedly connected to the lower corner of the T-shaped ALC plate, a connecting rod engaged at the lower end of the connecting block, and an adjusting sleeve sleeved at the lower end of the connecting rod, an installation plate fixedly installed on the upper end of the T-shaped ALC plate, and an installation nail inserted into the installation plate, an L-shaped ALC plate fixedly installed on the upper end of the installation plate, and sealing strips affixed to both the left and right sides of the lower end of the L-shaped ALC plate.

[0007] Preferably, both the T-shaped ALC plate and the L-shaped ALC plate have cavities inside, and the cavities are filled with glass wool.

[0008] Preferably, the drainage groove is formed on the lower surface of the T-shaped ALC plate and the upper surface of the L-shaped ALC plate.

[0009] Preferably, the upper left and right sides of the connecting rod are fixedly connected with rubber circular blocks. The inner wall of the connecting block is provided with a groove that matches the rubber circular blocks. The upper end of the connecting rod is engaged with the connecting block, and the connecting rod can be engaged with the connecting block by the rubber circular blocks.

[0010] Preferably, the lower end of the connecting rod has uniformly threaded grooves on its outer surface, the adjusting sleeve is threaded onto the connecting rod, and a rubber anti-slip pad is fixedly connected to the lower surface of the adjusting sleeve, so that the horizontal height of the plate can be adjusted by rotating the adjusting sleeve.

[0011] Preferably, the mounting plate is L-shaped, with its lower end fixed to the T-shaped ALC plate by mounting nails. Both the mounting plate and the T-shaped ALC plate have slots that mate with the mounting nails. The other end of the mounting plate is fixed to the L-shaped ALC plate by mounting nails, and both the mounting plate and the L-shaped ALC plate have slots that mate with the mounting nails. The device can be installed or removed using the mounting plate and mounting nails.

[0012] Preferably, the sealing strip is configured in an L-shape, with the upper end of the sealing strip attached to the L-shaped ALC plate and the lower end of the sealing strip attached to the T-shaped ALC plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The drainage grooves on the underside of the T-shaped ALC board can quickly drain rainwater or condensation, preventing water from seeping into the wall and reducing the risk of board expansion, cracking, or mold growth caused by moisture erosion. The sealing strips on both sides of the bottom of the L-shaped ALC board fit tightly against the T-shaped ALC board, forming a double seal to prevent horizontal water from seeping into the joints and enhance the waterproofness of the joints.

[0014] The connecting block and connecting rod at the lower end of the T-shaped ALC panel are fixed by a snap-fit ​​mechanism, forming a rigid node that resists horizontal displacement caused by wind loads or earthquakes, preventing the panel from loosening or falling off. The adjusting sleeve at the lower end of the connecting rod can fine-tune the connection tightness, absorbing minor deformations caused by temperature changes or construction errors, avoiding stress concentration that could lead to panel cracking, and solving installation problems caused by uneven ground or construction errors, ensuring the panel is flat. The mounting plate at the upper end of the L-shaped ALC panel is directly fixed to the wall with mounting nails, eliminating the need for mortar bonding or complex welding, shortening construction time and reducing labor intensity. The connecting block, connecting rod, adjusting sleeve, and other components are all prefabricated standardized parts, requiring only snap-fit ​​or plug-in connection on-site, reducing reliance on worker skills and improving installation accuracy.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides a technical solution: an L-shaped ALC plate and a T-shaped ALC plate installation structure, including a T-shaped ALC plate 1, a drainage groove 2 on the lower surface of the T-shaped ALC plate 1, a connecting block 3 fixedly connected to the lower corner of the T-shaped ALC plate 1, and a connecting rod 4 engaged at the lower end of the connecting block 3, and an adjusting sleeve 5 sleeved at the lower end of the connecting rod 4, an installation plate 6 fixedly installed at the upper end of the T-shaped ALC plate 1, and an installation nail 7 inserted on the installation plate 6, an L-shaped ALC plate 8 fixedly installed at the upper end of the installation plate 6, and sealing strips 9 affixed to the lower left and right sides of the L-shaped ALC plate 8.

[0019] Both the T-shaped ALC panel 1 and the L-shaped ALC panel 8 have internal cavities filled with glass wool. Drainage channels 2 are located on the lower surface of the T-shaped ALC panel 1 and the upper surface of the L-shaped ALC panel 8. The internal cavities of the ALC panels already have a certain degree of thermal insulation and sound insulation. Filling them with glass wool further enhances their performance. The porous structure of the glass wool effectively blocks heat conduction and reduces heat exchange between the inside and outside of the wall, making it suitable for energy-efficient buildings. Glass wool absorbs sound wave energy and reduces noise penetration through the wall, making it especially suitable for noise-sensitive areas (such as offices and residences). When T-shaped ALC board 1 and L-shaped ALC board 8 are combined, the internal glass wool forms a continuous sound and heat insulation layer, covering the longitudinal and transverse wall joints to avoid thermal or acoustic bridging effects. It also allows rainwater or condensate to drain quickly, preventing water from seeping into the wall and causing the ALC board to absorb moisture, deform, or become moldy. The drainage groove 2 on the upper surface of the L-shaped ALC board 8 prevents water from accumulating at the joints of the boards (such as from roof leaks) and reduces the erosion of the glass wool and ALC board by moisture. The drainage groove 2 also directs water to the outside, preventing water from seeping down the wall and protecting the thermal insulation performance of the glass wool and the durability of the ALC board.

[0020] Rubber circular locking blocks are fixedly connected to both the left and right sides of the upper end of the connecting rod 4. The inner wall of the connecting block 3 has grooves that mate with the rubber circular locking blocks. The upper end of the connecting rod 4 is engaged with the connecting block 3. Threaded grooves are evenly distributed on the outer surface of the lower end of the connecting rod 4. The adjusting sleeve 5 is threaded onto the connecting rod 4. A rubber anti-slip pad is fixedly connected to the lower surface of the adjusting sleeve 5. The rubber circular locking blocks at the upper end of the connecting rod 4 are embedded in the grooves on the inner wall of the connecting block 3, forming a flexible locking structure that restricts the lateral displacement of the connecting rod 4 and prevents loosening or detachment due to wind load or vibration. The rubber material provides elastic cushioning, absorbing minor deformations caused by installation errors or thermal expansion and contraction, and avoiding stress concentration. The threaded grooves at the lower end of the connecting rod 4 are fixed to the adjusting sleeve 5 by threaded engagement, allowing adjustment of the connection tightness. By rotating the adjusting sleeve 5, the vertical tightening of the connecting rod 4 can be precisely controlled. The adjustable sleeve 5 adapts to different wall thicknesses or construction errors. The threaded connection provides high shear strength, preventing the connecting rod 4 from sliding under gravity or lateral force. The rubber clip can undergo slight deformation under earthquake or wind load, absorbing vibration energy, reducing the impact force transmitted to the plate, reducing the stress caused by vibration at the joint, avoiding plate cracking or loosening of the connector, and enhancing the seismic performance of the overall structure. It is especially suitable for high-rise buildings or earthquake-prone areas. The rubber anti-slip pad on the lower surface of the adjusting sleeve 5 fits against the contact surface (such as the ground or foundation), increasing friction and dispersing pressure, preventing the adjusting sleeve 5 from slipping due to external forces (such as wind load), ensuring the stability of the connection joint, further absorbing vibration energy, and reducing the impact on the plate and connecting rod 4. By rotating the adjusting sleeve 5, the height and tightness of the connecting rod 4 can be finely adjusted to compensate for construction errors or differences in plate thickness.

[0021] Mounting plate 6 is L-shaped. The lower end of mounting plate 6 is fixed to T-shaped ALC plate 1 by mounting nails 7. Both mounting plate 6 and T-shaped ALC plate 1 have slots that mate with the mounting nails 7. The other end of mounting plate 6 is fixed to L-shaped ALC plate 8 by mounting nails 7. Both mounting plate 6 and L-shaped ALC plate 8 have slots that mate with the mounting nails 7. Sealing strip 9 is L-shaped. The upper end of sealing strip 9 is attached to L-shaped ALC plate 8, and the lower end of sealing strip 9 is attached to T-shaped ALC plate 1. One end of the L-shaped structure of mounting plate 6 is fixed to T-shaped ALC plate 1 by mounting nails 7. One end of the T-shaped ALC plate 1 is fixed to the other end of the L-shaped ALC plate 8, forming a "corner bracket" connection. This tightly integrates the T-shaped and L-shaped plates into a whole, enhancing the shear and pull-out resistance of the joint and preventing displacement of the plates due to wind load or vibration. The L-shaped plate acts as a rigid support, distributing external forces to the two plates and reducing the risk of stress concentration at the joint. Slots matching the mounting nails 7 are provided on the mounting plate 6, T-shaped ALC plate 1, and L-shaped ALC plate 8 for precise positioning. The upper end of the L-shaped structure of the sealing strip 9 is attached to the L-shaped ALC plate 8, and the lower end is attached to the T-shaped ALC plate 1, covering the horizontal and vertical directions of the joint. A continuous sealing layer is formed, preventing rainwater, condensation, or dust from seeping into the wall through the joints. Double bonding (top and bottom) avoids the risk of failure at a single sealing point, improving waterproofing reliability. The L-shaped structure of sealing strip 9 complements the L-shaped structure of mounting plate 6, covering the outer edge and inner corner of the joint, preventing moisture from seeping along the edges of the board or through the holes of mounting nails 7, protecting the internal glass wool and cavity structure. The elastic material of sealing strip 9 compensates for minor deformations of the board caused by temperature changes, preventing seal failure. Both mounting plate 6 and sealing strip 9 are prefabricated L-shaped structures; on-site installation only requires inserting and tightening the mounting nails 7, eliminating the need for on-site cutting or re-installation. For complex adjustments, the mounting nails 7 are typically made of galvanized or stainless steel. Combined with the slot design, this reduces direct contact between metal parts and the sheet metal, lowering the risk of corrosion. The sealing strip 9 is made of weather-resistant rubber or silicone, resistant to ultraviolet rays, high and low temperatures, and is not prone to aging with long-term use. This prevents joint leakage caused by corrosion or aging of the sealing strip 9, extending the service life of the wall. It adapts to harsh environments such as humidity and acid / alkali, ensuring the stability of the joint. The synergistic effect of the L-shaped mounting plate 6 and the sealing strip 9 absorbs thermal expansion and contraction or slight deformation of the sheet metal, reducing the probability of cracking at the joint and lowering the risk of moisture infiltration or decreased sound insulation performance due to cracks.

[0022] Working principle: Connecting block 3 is fixed at the lower corner of T-shaped ALC plate 1, serving as the base for the connecting node. Its inner wall has a slot that engages with the rubber circular locking block on connecting rod 4 to achieve initial locking. The upper end of connecting rod 4 is engaged in the slot of connecting block 3 via the rubber locking block, forming an elastic limit to prevent lateral displacement. The lower end of connecting rod 4 is inserted into adjusting sleeve 5 and fixed by screwing, providing vertical tightening force. Adjusting sleeve 5 is threaded onto connecting rod 4 and can be rotated to compensate for construction errors or differences in plate thickness. The rubber anti-slip pad on the lower surface of adjusting sleeve 5 increases friction to prevent slippage and absorbs vibration energy. (The last sentence appears to be incomplete and possibly refers to a different process.) Mounting plate 6 is L-shaped, with one end fixed to the T-shaped ALC plate 1 by mounting nail 7 and the other end fixed to the L-shaped ALC plate 8, forming a two-way connection. The L-shaped structure provides rigid support, dispersing external forces to the two plates and avoiding stress concentration at the joint. Mounting plate 6, T-shaped ALC plate 1 and L-shaped ALC plate 8 are all provided with slots that match the mounting nail 7 to achieve precise positioning. After the mounting nail 7 is inserted into the slot, it is tightened to fix mounting plate 6 and the two ALC plates into a whole, ensuring the stability of the joint. Sealing strip 9 is L-shaped, with the upper end attached to the lower surface of L-shaped ALC plate 8 and the lower end attached to the upper surface of T-shaped ALC plate 1, covering the horizontal and vertical directions of the joint.

[0023] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
