Description

Technical Field

[0001] This invention relates to the field of ALC wall panel technology, and more particularly to a support component and construction method for vertically mounted ALC panels. Background Technology

[0002] Based on the current strong trend of industrialization and green development in the construction industry, the combined application of ALC panels (autoclaved aerated concrete panels) and steel structures, with its excellent "performance complementarity" (the steel structure frame provides load-bearing capacity and speed + ALC enclosure provides high-efficiency fire protection, thermal insulation, sound insulation and lightweight advantages) and its high degree of compatibility with the core requirements of "standardized design, factory production and assembly construction" of prefabricated buildings, is becoming a key solution to solve the pain points of steel structure building enclosure systems.

[0003] However, the current "Autoclaved Aerated Concrete Slab" atlas only provides selection guidelines for slabs with a thickness of 200mm, and lacks clear procedures for slabs with a thickness of more than 200mm. This results in a technical blind spot in the application of ultra-thick slabs, causing significant problems for construction and design.

[0004] Chinese patent application number CN202110558374.5 discloses a connector, an ALC installation node structure, and a construction method. This invention connects a first ALC strip via a first U-shaped groove facing a first direction and a second ALC strip via a second U-shaped groove facing a second direction. Therefore, it eliminates the need for any holes in the ALC strips to be installed, avoiding the risk of damage. Furthermore, since no holes need to be drilled on either side of the ALC strips, it effectively improves the construction efficiency of the wall.

[0005] However, when ALC plates with a thickness exceeding 200mm are subjected to large wind and vibration loads, if they are fixed solely by hook bolts or conventional connectors at the top and bottom ends, repeated wind vibration will cause stress concentration around the anchor bolt holes (local pressure peaks exceeding 6MPa), resulting in the crushing of the brittle ALC substrate. Furthermore, if there are welding defects or errors in joint treatment during construction, microcracks will develop in the welds under alternating stress in areas with frequent vibration or wind loads. In severe cases, bolt weld failure may occur. Weld failure will cause the ALC plate to lose its anchor support, and under dynamic loads, the failure of a single bolt can lead to stress redistribution at adjacent nodes, accelerating fatigue cracking of the surrounding welds.

[0006] In addition, when ALC panels are installed vertically, the lack of tongue and groove joints at the upper and lower splicing ends can induce misalignment between panels due to the high wind pressure environment of the exterior walls of high-rise buildings, making the joints a weak point. Horizontal misalignment damages the integrity of the sealing layer, and vibration loads accelerate the aging of the sealant, ultimately leading to the failure of both air tightness and water tightness.

[0007] To address these issues, this invention proposes a support component and construction method for vertically mounted ALC plates. Summary of the Invention

[0008] The purpose of this invention is to provide a support for vertically mounted ALC plates and a construction method therefor, so as to solve the technical problems mentioned in the background art.

The anti-loosening component includes a fixing plate that is fixedly connected to the angle steel. A clamping component is provided on the fixing plate. The clamping component fixes the hook bolt under the gravity of the upper ALC plate.

[0012] Preferably, the ALC plate has bolt holes extending through both sides along its length, the hook bolts are located in the bolt holes, and the mounting groove includes a horizontal groove at the top of the ALC plate and a vertical groove communicating with the bolt holes.

[0013] Preferably, the clamping component includes a fixed cylinder located in the mounting groove, the bottom of the fixed cylinder having a through hole matching the hook bolt, a movable plate slidably connected inside the fixed cylinder, a first clamping surface being provided at the bottom of the fixed cylinder, a second clamping surface being provided at one end of the movable plate cooperating with the first clamping surface, the hook bolt being located between the first clamping surface and the second clamping surface, and a connecting plate being provided at the end of the movable plate away from the second clamping surface, the connecting plate contacting the bottom of the adjacent ALC plate.

[0014] Preferably, the first clamping surface and the second clamping surface are respectively provided with arc surfaces that abut against the hook bolt, and the two arc surfaces are arranged diagonally.

[0015] Preferably, the connecting plate is slidably connected to the fixed cylinder in a sealed manner. The connecting plate has a first inclined surface, and the top of the movable plate is provided with a second inclined surface that cooperates with the first inclined surface. When the connecting plate moves downward under the pressure of the ALC plate, the movable plate can move to one side under the action of the first and second inclined surfaces.

[0016] Preferably, the anti-loosening component further includes a connecting strip disposed on the side of the movable plate near the steel structure column, and a compensation plate matching the mounting groove is disposed at one end of the connecting strip extending out of the fixing cylinder, and the connecting strip and the fixing cylinder are clearance fit.

[0017] Preferably, the length of the connecting plate is the same as the width of the ALC plate.

[0018] Preferably, the compensation plate has a connecting groove on the side near the connecting strip, the connecting strip is slidably connected to the connecting groove, the movable plate and the connecting strip have a first flow channel communicating with the connecting groove inside, the top of the connecting plate has a sealing groove, an elastic sealing element is fixedly connected in the sealing groove, the connecting plate has a second flow channel communicating with the sealing groove, and the first flow channel, the second flow channel, the sealing groove and the connecting groove are filled with a flowing medium.

[0019] Preferably, the second inclined surface has a groove that matches the first flow channel and the second flow channel.

[0020] A method for installing vertically mounted ALC panels includes the following steps:

[0021] S1: Weld the first and second continuous angle irons onto the steel structure column;

[0022] S2: Weld the load-bearing components to the side of the first continuous angle iron along the length of the steel structure column, and the spacing between adjacent load-bearing components matches the width of the ALC plate;

[0023] S3: Pre-drill bolt holes and mounting slots on the ALC board, and clean the bolt holes and mounting slots using cleaning equipment;

[0024] S4: Hoist the ALC plate above the load-bearing component and make the side of the plate tightly against the steel structure column, and fix the bottom of the ALC plate with hook bolts;

[0025] S5: Install the anti-loosening component into the mounting slot, and tighten the nut after passing the hook bolt through the through hole;

[0026] S6: Weld the support component again above the fixed ALC plate, and weld the anti-loosening component to the matching support component. Then, hoist the ALC plate above the support component and align it with the ALC plate below it, and then fix it to the support component.

[0027] S7: Weld and fix the hook bolts of the lower ALC plate and perform waterproof sealing treatment at the upper and lower joints;

[0028] S8: Repeat the above steps until all ALC boards are installed.

[0029] The beneficial effects of this invention are:

[0030] This invention utilizes a connecting plate, a movable plate, a connecting strip, a compensating plate, and elastic seals to provide secondary tightening and fixing of the hook bolts, preventing high-frequency vibration in areas with frequent vibration or wind loads, and improving or even preventing weld cracking under alternating stress. Furthermore, even if weld failure occurs, the movable plate and fixed cylinder's fixation of the hook bolts prevents rotation under vibration, significantly improving the stability of the connection between the ALC plate and the steel structure. Additionally, the upper ALC plate applies pressure to the connecting plate, causing the movable plate to move and change the volume of the connecting groove, thereby adjusting the compensating plate's support force on the ALC plate. When the ALC plate and steel columns experience thermal expansion and contraction, the compensating plate dynamically adjusts according to the expansion during heating or the contraction during cooling, and adjusts the deformation of the elastic seals during this dynamic adjustment. This improves the load-bearing capacity of the ALC plate while preventing airtightness and watertightness failure of the ALC exterior wall due to inter-plate misalignment.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] In the actual installation of ALC panels, the current "Autoclaved Aerated Concrete Panels" atlas only provides selection guidelines for 200mm thick panels, lacking clear procedures for panels exceeding 200mm, resulting in a technical blind spot in the application of ultra-thick panels. Furthermore, when ALC panels exceeding 200mm in thickness are subjected to significant wind and vibration loads, relying solely on hook bolts or conventional connectors for fixation at the top and bottom ends will lead to stress concentration around the anchor bolt holes due to repeated wind vibration. Moreover, if welding defects or improper joint treatment occur during construction, microcracks may develop in the welds under alternating stress in areas with frequent vibration or wind loads, potentially leading to bolt weld failure in severe cases. This embodiment is invented to address these issues.

[0052] Please see Figures 1 to 12As shown, a support for a vertically mounted ALC plate according to an embodiment of the present invention includes an ALC plate 1, hook bolts 2, and a steel structure column 3. The ALC plate 1 is disposed on the outside of the steel structure column 3, and the floor slab is above the steel structure column 3. The ALC plate 1 is vertically mounted and a bearing member 4 is provided at the splice of two adjacent ALC plates 1. A first continuous angle iron 31 and a second continuous angle iron 32 are fixedly connected to the upper and lower sides of the steel structure column 3, respectively. The bearing member 4 is fixedly connected to the first continuous angle iron 31, and cement grout or sealant is filled between the floor slab and the first continuous angle iron 31.

[0053] The bearing member 4 includes an angle steel 41 fixed to the first continuous angle iron 31. A stiffening plate 42 is fixedly connected to the middle of the angle steel 41. The bearing member 4 is located in the middle of the ALC plate 1 or at the joint of two adjacent ALC plates 1.

[0054] In this embodiment, the angle steel 41 and the stiffening plate 42 are located in the middle of the ALC plate 1. When the ALC plate 1 is supported and fixed in this way, a groove consistent with the stiffening plate 42 needs to be opened in advance at the bottom of the ALC plate 1.

[0055] Please see Figures 4 to 8 As shown, the top of the ALC plate 1 is provided with an installation groove 11 that matches the hook bolt 2. An anti-loosening component 5 is provided in the installation groove 11. The anti-loosening component 5 includes a fixing plate 51 that is fixedly connected to the angle steel 41. A clamping member 52 is provided on the fixing plate 51. The clamping member 52 fixes the hook bolt 2 under the gravity of the upper ALC plate 1.

[0056] Bolt holes are provided on both sides of the ALC plate 1 along its length. Hook bolts 2 are located in the bolt holes. The mounting groove 11 includes a horizontal groove 111 located at the top of the ALC plate 1 and a vertical groove 112 communicating with the bolt holes. The mounting groove 11 is in the shape of a "T".

[0057] Please see Figures 9 to 12 As shown, the clamping member 52 includes a fixed cylinder 521 located in the mounting groove 11. The bottom of the fixed cylinder 521 is provided with a through hole 522 that matches the hook bolt 2. In this embodiment, the through hole 522 is an obliquely arranged waist-shaped hole. A movable plate 523 is slidably connected inside the fixed cylinder 521. A first clamping surface 524 is provided at the bottom of the fixed cylinder 521. A second clamping surface 525 that cooperates with the first clamping surface 524 is provided at one end of the movable plate 523. The hook bolt 2 is located between the first clamping surface 524 and the second clamping surface 525. A connecting plate 53 is provided at the end of the movable plate 523 away from the second clamping surface 525. The connecting plate 53 contacts the bottom of the adjacent ALC plate 1.

[0058] In this embodiment, the first clamping surface 524 and the second clamping surface 525 are mutually cooperating inclined surfaces.

[0059] It should also be noted that when the upper ALC plate 1 does not compress the connecting plate 53, the connecting plate 53 protrudes slightly from the bottom of the angle steel 41.

[0060] Please see Figure 10 As shown, the first clamping surface 524 and the second clamping surface 525 are respectively provided with arc surfaces that abut against the hook bolt 2, and the two arc surfaces are arranged diagonally.

[0061] During operation, when the anti-loosening component 5 is installed in the mounting slot 11 and the ALC plate 1 is installed in an overlapping manner, the connecting plate 53 inside the anti-loosening component 5 is pressed down by the upper ALC plate 1 and moves downward. The movable plate 523 is pressed down by the connecting plate 53 and tends to move diagonally downward. At this time, the pressure exerted by the arc surface on the movable plate 523 on the hook bolt 2 rod body is greatly enhanced.

[0062] In summary, by using the connecting plate 53, the movable plate 523, and the arc surface, the hook bolt 2 is tightened and fixed a second time, preventing it from generating high-frequency vibration in areas with frequent vibration or wind loads, thus improving or even avoiding cracks in the weld under alternating stress. Furthermore, even if weld failure occurs, the fixation of the hook bolt 2 by the movable plate 523 and the fixed cylinder 521 can prevent it from rotating under vibration, greatly improving the stability of the connection between the ALC plate 1 and the steel structure.

[0063] Example 2

[0064] When ALC panels are installed vertically, the lack of tongue-and-groove joints at the upper and lower splicing ends can induce misalignment between panels due to the high wind pressure environment of high-rise building exterior walls. This makes the joints a weak point—horizontal misalignment damages the integrity of the sealing layer, vibration loads accelerate the aging of the sealant, and ultimately lead to failure of both airtightness and watertightness. Further improvements are made based on the above embodiments.

[0065] Please see Figures 9 to 12 As shown, the connecting plate 53 is slidably connected to the fixed cylinder 521. The connecting plate 53 has a first inclined surface, and the top of the movable plate 523 is provided with a second inclined surface that cooperates with the first inclined surface. When the connecting plate 53 moves downward under the pressure of the ALC plate 1, the movable plate 523 can move to one side under the action of the first and second inclined surfaces.

[0066] The anti-loosening component 5 also includes a connecting strip 54 set on the side of the movable plate 523 near the steel structure column 3. One end of the connecting strip 54 extending out of the fixed cylinder 521 is provided with a compensation plate 55 that matches the mounting groove 11. The connecting strip 54 and the fixed cylinder 521 are in clearance fit.

[0067] In this embodiment, in order for the connecting plate 53 and other structures to achieve a stronger sealing effect, the length of the connecting plate 53 is the same as the width of the ALC plate 1.

[0068] In this embodiment, in order to prevent the compensation plate 55 from being restricted by gravel, debris, etc. during the movement, the two ends of the compensation plate 55 are provided with conical plates, and the two ends of the fixing cylinder 521 are provided with sliding grooves that match the conical plates. When the compensation plate 55 moves along the sliding groove, the conical plates can prevent gravel and other debris from entering the gap between the compensation plate 55 and the fixing cylinder 521, and the length of the compensation plate 55 along the vertical groove 112 is less than the depth of the vertical groove 112.

[0069] A connecting groove 551 is provided on the side of the compensation plate 55 near the connecting strip 54. The connecting strip 54 is slidably connected to the connecting groove 551, and an elastic element is provided between the connecting strip 54 and the connecting groove 551. A first flow channel 56 communicating with the connecting groove 551 is provided inside the movable plate 523 and the connecting strip 54. A sealing groove 531 is provided on the top of the connecting plate 53. An elastic sealing element 57 is fixedly connected in the sealing groove 531. A second flow channel 532 communicating with the sealing groove 531 is provided in the connecting plate 53. The first flow channel 56, the second flow channel 532, the sealing groove 531 and the connecting groove 551 are filled with a flowing medium.

[0070] In this embodiment, the flowing medium is compressed gas.

[0071] In order to ensure that the first flow channel 56 and the second flow channel 532 can still be connected when the movable plate 523 moves, a groove 58 matching the first flow channel 56 and the second flow channel 532 is provided on the second inclined surface.

[0072] Based on the above embodiments, during use, when the connecting plate 53 is squeezed and moves downward, the movable plate 523 not only has a downward tendency, but also moves towards the steel structure column 3 under the action of the first inclined surface and the second inclined surface. At this time, the compressed gas in the connecting groove 551 is further compressed, which makes the support of the compensation plate 55 on the ALC plate 1 stronger. When the ALC plate 1 and the steel structure column 3 and other components experience thermal expansion and contraction, the compensation plate 55 can be dynamically adjusted according to the amount of expansion when heated or the amount of contraction when cooled.

[0073] In addition, when the volume of the connecting groove 551 is further reduced, the compressed gas enters the sealing groove 531 through the first flow channel 56 and the second flow channel 532. At this time, the elastic seal 57 is tightly attached to the bottom surface of the upper ALC plate 1 under the action of the compressed gas.

[0074] In summary, by using the connecting strip 54, the compensation plate 55, and the elastic seal 57, the upper ALC plate 1 is further used to apply pressure to the connecting plate 53, causing the movable plate 523 to move under the drive of the connecting plate 53 and change the volume of the connecting groove 551. This adjusts the supporting force of the compensation plate 55 on the ALC plate 1. When the ALC plate 1 and the steel structure column 3 experience thermal expansion and contraction, the compensation plate 55 can dynamically adjust according to the amount of expansion when heated or the amount of contraction when cooled. During the dynamic adjustment process, the deformation of the elastic seal 57 is also adjusted. This improves the load resistance of the ALC plate 1 and prevents the airtightness and watertightness of the ALC exterior wall from failing due to misalignment between the plates.

[0075] Example 3

[0076] A method for installing vertically mounted ALC panels includes the following steps:

[0077] S1: Weld the first through-length angle iron 31 and the second through-length angle iron 32 to the steel structure column 3.

[0078] S2: The bearing member 4 is welded to the side of the first continuous angle iron 31 along the length of the steel structure column 3, and the spacing between adjacent bearing members 4 matches the width of the ALC plate 1.

[0079] S3: Bolt holes and mounting grooves 11 are pre-drilled on ALC plate 1, and the bolt holes and mounting grooves 11 are cleaned using cleaning equipment.

[0080] S4: Hoist the ALC plate 1 above the bearing 4 and make the side of the plate tightly against the steel structure column 3, and use hook bolts 2 to fix the bottom of the ALC plate 1.

[0081] S5: Install the anti-loosening component 5 into the mounting slot 11, and tighten the nut after passing the hook bolt 2 through the through hole 522.
