Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ALC wallboard, and particularly relates to a support for vertical ALC board and a construction method. BACKGROUND

[0002] Based on the strong trend of current building industrialization and green development, the combination application of ALC board (autoclaved aerated concrete board) and steel structure is becoming a key solution to solve the pain points of steel structure building enclosure system, with its outstanding performance complementarity (steel structure skeleton provides bearing capacity and speed + ALC enclosure provides efficient fire prevention, heat preservation, sound insulation and lightweight advantages) and high compatibility with the core requirements of prefabricated building (standardized design, factory production and assembly construction).

[0003] However, the current "autoclaved aerated concrete board" atlas only provides selection basis for 200mm thick boards, and lacks clear methods for boards exceeding 200mm, resulting in a technical blind spot in the application of super-thick boards, causing significant difficulties for construction and design.

[0004] A connecting piece, ALC mounting node structure and construction method are disclosed in Chinese patent No. CN202110558374.5. The first U-shaped groove facing the first direction is nested to connect the first ALC strip board, and the second U-shaped groove facing the second direction is nested to connect the second ALC strip board, so that no hole structure needs to be opened on the ALC strip board to be installed, avoiding the risk of damage to the ALC strip board, and the construction efficiency of the wall body can be effectively improved without the need to open holes on both sides of the ALC strip board.

[0005] However, when the ALC board with a thickness exceeding 200mm bears a large wind load and vibration load, if only the hook bolts or conventional connecting pieces at the upper and lower ends are relied on for fixation, repeated wind vibration will cause stress concentration around the anchor bolt hole (local pressure peak exceeding 6MPa), causing the ALC brittle substrate to be crushed, and if there are welding defects, node processing errors and other problems during construction, in areas with frequent vibration or wind load, micro-cracks will be generated in the weld under alternating stress, and in severe cases, bolt weld failure and other problems will occur, and weld failure will cause the ALC board to lose anchoring support, and under dynamic load, the failure of a single bolt can cause stress redistribution of adjacent nodes, accelerating the fatigue cracking of the surrounding weld.

[0006] In addition, when the ALC board is installed vertically, since the upper and lower spliced boards are not provided with a rebate structure, the high wind pressure environment of the outer wall of a high-rise building can induce misalignment between the boards, making the joint a weak link - horizontal misalignment destroys the integrity of the sealing layer, vibration load accelerates the aging of the joint filling material, and ultimately leads to double failure of air tightness and water tightness.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment 1 In the actual installation process of the ALC plate, since the current "Autoclaved Aerated Concrete Plate" atlas only provides selection basis for the 200mm thick plate, and lacks explicit methods for plates exceeding 200mm, leading to a technical blind area in the application of super-thick plates; and when the ALC plate with a thickness exceeding 200mm bears a large wind load and a vibration load, if only relying on the hook bolts or conventional connecting members at the upper and lower ends for fixation, repeated wind vibration will cause stress concentration around the anchor bolt holes, and if there are welding defects, node processing errors and other problems during construction, in the area with frequent vibration or wind load, micro-cracks will be generated in the weld under alternating stress, and in severe cases, bolt weld failure and other problems will occur. To solve the above problems, the present embodiment is invented.

[0036] The bearing 4 comprises an angle steel 41 fixed with the first through angle iron 31, the middle part of the angle steel 41 is fixedly connected with a stiffened plate 42, and the bearing 4 is located at the middle part of the ALC plate 1 or the joint of two adjacent ALC plates 1.

[0037] In this embodiment, the angle steel 41 and the stiffened plate 42 are located at the middle part of the ALC plate 1, and when the ALC plate 1 is supported and fixed in this way, a notch consistent with the stiffened plate 42 needs to be previously formed at the bottom of the ALC plate 1.

[0038] As shown in the figure, Figures 4 to 8 The top of the ALC plate 1 is provided with a mounting groove 11 matched with the hook bolt 2, the mounting groove 11 is provided with a locking assembly 5, the locking assembly 5 comprises a fixed plate 51 fixedly connected with the angle steel 41, the fixed plate 51 is provided with a clamping piece 52, and the clamping piece 52 is fixed to the hook bolt 2 under the gravity of the upper ALC plate 1.

[0039] The ALC plate 1 is provided with bolt holes penetrating through the two sides along the length direction, the hook bolt 2 is located in the bolt hole, the mounting groove 11 comprises a horizontal groove 111 located at the top of the ALC plate 1 and a vertical groove 112 communicated with the bolt hole, and the mounting groove 11 as a whole presents a "T" type structure.

[0040] As shown in the figure, Figures 9 to 12 The clamping piece 52 comprises a fixed cylinder 521 located in the mounting groove 11, the bottom of the fixed cylinder 521 is provided with a through hole 522 matched with 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 in the fixed cylinder 521, the bottom of the fixed cylinder 521 is provided with a first clamping surface 524, one end of the movable plate 523 is provided with a second clamping surface 525 matched with the first clamping surface 524, the hook bolt 2 is located between the first clamping surface 524 and the second clamping surface 525, the end of the movable plate 523 away from the second clamping surface 525 is provided with a connecting plate 53, and the connecting plate 53 is in contact with the bottom of the adjacent ALC plate 1.

[0041] In this embodiment, the first clamping surface 524 and the second clamping surface 525 are inclined surfaces matched with each other.

[0042] And it needs to be noted that when the upper ALC plate 1 does not cause extrusion to the connecting plate 53, the connecting plate 53 is slightly protruding from the bottom of the angle steel 41.

[0043] Please refer to Figure 10 As shown in the figure, the first clamping surface 524 and the second clamping surface 525 are respectively provided with a circular arc surface which is in abutment with the hook bolt 2, and the two circular arc surfaces are diagonally arranged.

[0044] In work, when the anti-loose assembly 5 is installed into the installation groove 11 and the ALC plate 1 is installed in an upper and lower overlapping manner, the connecting plate 53 inside the anti-loose assembly 5 is extruded by the upper ALC plate 1 and moves downward, and the movable plate 523 is extruded by the connecting plate 53 and has a tendency to move obliquely downward, at this time, the extrusion force of the circular arc surface on the movable plate 523 on the rod body part of the hook bolt 2 is greatly enhanced.

[0045] In summary, through the arrangement of the connecting plate 53, the movable plate 523 and the circular arc surface, etc., the hook bolt 2 is fixed twice, which prevents it from producing high-frequency vibration in the area with frequent vibration or wind load, improves or even avoids the cracks in the weld under alternating stress; and even if the weld failure problem occurs, the fixing of the hook bolt 2 by the movable plate 523 and the fixed cylinder 521 can prevent it from rotating in the vibration condition, greatly improving the stability of the connection between the ALC plate 1 and the steel structure.

[0046] Embodiment 2 When the ALC plate is installed vertically, since the upper and lower spliced plates are not provided with a tongue and groove structure, the high wind pressure environment of the high-rise building outer wall can induce the dislocation between the plates, so that the joint becomes a weak link, the horizontal dislocation destroys the integrity of the sealing layer, the vibration load accelerates the aging of the filling material, and finally leads to the double failure of air tightness and water tightness. Further improvement is made on the basis of the above embodiment.

[0047] Please refer to Figures 9 to 12 As shown in the figure, the connecting plate 53 and the fixed cylinder 521 are sealingly and slidingly connected, the connecting plate 53 has a first inclined surface, the top of the movable plate 523 is provided with a second inclined surface matched with the first inclined surface, and when the connecting plate 53 moves downward under the extrusion of the ALC plate 1, the movable plate 523 can move to one side under the drive of the first inclined surface and the second inclined surface.

[0048] The anti-loose assembly 5 further comprises a connecting strip 54 arranged on the side close to the steel structure column 3 of the movable plate 523, one end of the connecting strip 54 extending out of the fixed cylinder 521 is provided with a compensation plate 55 matched with the installation groove 11, and the connecting strip 54 and the fixed cylinder 521 are gap-fitted.

[0049] In this embodiment, in order to enable the connecting plate 53 and the like to have the effect of strengthening the sealing, the length of the connecting plate 53 is consistent with the width of the ALC plate 1.

[0050] In the embodiment, in order to prevent the compensation plate 55 from being restricted by gravel, debris and the like during movement, tapered head plates are arranged at both ends of the compensation plate 55, and sliding grooves matching the tapered head plates are arranged at both ends of the fixed cylinder 521. When the compensation plate 55 moves along the sliding grooves, the tapered head plates can prevent gravel and the like from entering the gap between the compensation plate 55 and the fixed 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.

[0051] A connecting groove 551 is arranged at one side of the compensation plate 55 close to the connecting strip 54, the connecting strip 54 and the connecting groove 551 are sealingly and slidably connected, and an elastic member is arranged between the connecting strip 54 and the connecting groove 551. A first flow channel 56 in communication with the connecting groove 551 is arranged in the inside of the movable plate 523 and the connecting strip 54. A sealing groove 531 is arranged at the top of the connecting plate 53, and an elastic sealing member 57 is fixedly connected in the sealing groove 531. A second flow channel 532 in communication with the sealing groove 531 is arranged 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.

[0052] In the embodiment, the flowing medium is compressed gas.

[0053] In order to enable the movable plate 523 to still communicate the first flow channel 56 and the second flow channel 532 when moving, grooves 58 matching the first flow channel 56 and the second flow channel 532 are arranged on the second inclined surface.

[0054] On the basis of the above embodiment, when the connecting plate 53 is pressed to move downward during use, the movable plate 523 not only has a downward movement tendency, but also moves toward 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, so that the supporting property of the compensation plate 55 to the ALC plate 1 is improved. When the ALC plate 1 and the steel structure column 3 and the like components expand or contract due to heat or cooling, the compensation plate 55 can dynamically adjust according to the expansion amount or the contraction amount when heated.

[0055] 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 sealing member 57 tightly abuts the bottom surface of the upper ALC plate 1 under the action of the compressed gas.

[0056] In summary, by connecting the strip 54, the compensation plate 55 and the elastic seal 57, and further using the upper ALC plate 1 to press the connecting plate 53, the movable plate 523 is driven to move and change the volume of the connecting groove 551, so as to adjust the supporting force of the compensation plate 55 on the ALC plate 1. When the ALC plate 1 and the steel structure column 3 and other structures expand and contract due to heat, the compensation plate 55 can dynamically adjust according to the expansion amount when heated or the shrinkage amount when cooled, and adjust the deformation amount of the elastic seal 57 during dynamic adjustment. On the basis of improving the load-bearing capacity of the ALC plate 1, the air tightness and water tightness of the ALC outer wall surface are avoided due to the dislocation between the plates.

[0057] Embodiment 3 A construction method of a vertical ALC plate, comprising the following steps: S1: welding the first and second through-length angle irons 31 and 32 on the steel structure column 3.

[0058] S2: welding the bearing members 4 on the side of the first through-length angle iron 31 along the length direction of the steel structure column 3, and the spacing between adjacent bearing members 4 matches the width of the ALC plate 1.

[0059] S3: pre-drilling bolt holes and installation grooves 11 on the ALC plate 1, and cleaning the bolt holes and installation grooves 11 with cleaning equipment.

[0060] S4: hoisting the ALC plate 1 above the bearing members 4 and tightly attaching the plate side to the steel structure column 3, and fixing the bottom of the ALC plate 1 with the hook head bolt 2.

[0061] S5: installing the anti-loosening assembly 5 in the installation groove 11, and tightening the nut after the hook head bolt 2 passes through the through hole 522.

[0062] S6: welding the bearing members 4 above the fixed ALC plate 1, welding the anti-loosening assembly 5 and the matching bearing member 4, then hoisting the ALC plate 1 above the bearing member 4 and aligning it with the ALC plate 1 below, and fixing it with the bearing member 4.

[0063] S7: welding and fixing the hook head bolt 2 of the lower ALC plate 1 and waterproof sealing treatment at the upper and lower joints.

[0064] S8: repeating the above steps until the ALC plate 1 is completely installed.
