Description

Technical Field

[0001] This utility model belongs to the technical field of aerated concrete panels, and in particular relates to installation connectors for autoclaved aerated concrete panels. Background Technology

[0002] Autoclaved aerated concrete (ALC) panels are lightweight, porous concrete panels made primarily from siliceous materials (such as sand and fly ash) and calcareous materials (such as cement and lime). They are produced through processes such as batching, mixing, gas expansion, cutting, and autoclaving. Due to their lightweight, heat insulation, and fire resistance properties, they are widely used in prefabricated buildings.

[0003] During construction, a construction method of block-by-block masonry and cement mortar bonding is adopted. The installation of a single panel requires the cooperation of multiple people. When using bonding, the ALC panel has poor impact resistance. And when using expansion bolts to fix it one by one, the construction cycle is long. Therefore, it is necessary to provide autoclaved aerated concrete panel installation connectors. The installation position and angle of multiple panels are determined by using rapid positioning, mechanical anchoring and precise leveling. Finally, rapid fixing is achieved by welding.

Detailed Implementation

[0022] In the following description, embodiments of the autoclaved aerated concrete (AAC) panel installation connector of this invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates an embodiment of an autoclaved aerated concrete (AAC) panel installation connector, comprising a support rail 2 located on the surface of a wall 1; two concrete panels 3 are disposed between the two support rails 2; multiple connecting components 4 are disposed on the surface of the support rails 2; each connecting component 4 includes a connecting locking plate 41 slidably connected to the surface of the support rails 2; a positioning bolt 45 is disposed through the top of the inner cavity of the connecting locking plate 41, the top of the positioning bolt 45 contacting the bottom of the support rail 2; a first circular hole 46 adapted to the positioning bolt 45 is provided at the top of the inner cavity of the connecting locking plate 41; through the cooperation of the positioning bolt 45 and the first circular hole 46, the connecting locking plate 41 is temporarily locked, thereby enabling the connecting locking plate 41 to accurately position the joint of the two concrete panels 3, thus improving the connection stability between the multiple concrete panels 3; a limiting groove 42 is provided at the top of the connecting locking plate 41, the limiting groove 42 being slidably connected to the support rail 2. Welding positions 43 are provided on the surface of the support rail 2 and on the front and rear sides of the connecting clamping plate 41. Welds 44 are provided at the contact positions between the surface of the support rail 2 and the inner wall of the welding positions 43. Multiple second circular holes 5 are provided at the bottom of the support rail 2. An expansion sleeve 7 is provided through the inner cavity of the second circular hole 5. The expansion sleeve 7 is inserted into the interior of the wall 1. An expansion bolt 6 is provided through the inner cavity of the expansion sleeve 7. A nut 8 is threaded to the bottom of the surface of the expansion bolt 6. Through the cooperation of the expansion bolt 6 and the nut 8, the inner cavity of the expansion sleeve 7 is expanded, thereby increasing the diameter of the expansion sleeve 7 and enhancing the connection stability between the expansion sleeve 7 and the wall 1. An alignment protrusion 9 is provided on the right side of the concrete slab 3. An alignment concave surface 10 that matches the alignment protrusion 9 is provided on the left side of the concrete slab 3. Multiple wedge-shaped sleepers 11 are provided at the top and bottom of the concrete slab 3. The wedge-shaped sleepers 11 are located between the concrete slab 3 and the wall 1.

[0024] Working Principle: In use, the user drills the installation holes for the expansion sleeve 7 by marking out the lines. Then, the user marks out the installation position of the support rail 2. Next, the user places the required number of connecting clamping plates 41 on the surface of the support rail 2, hammers the expansion sleeve 7 into the installation holes, and uses a wrench to rotate the nut 8. During rotation, the surface of the nut 8 contacts the inner wall of the second circular hole 5. Continuing to rotate the nut 8 stretches the expansion bolt 6. During this stretching process, the expansion bolt 6 slides within the cavity of the expansion sleeve 7, compressing the inner wall of the expansion sleeve 7, causing the end of the expansion sleeve 7 to deform and expand, thereby enhancing the connection strength between the expansion sleeve 7 and the wall 1, and simultaneously fixing the support rail 2. Then, the user lays the concrete slab 3. After the first concrete slab 3 is laid, the user slides the connecting clamping plates 41 to the right side of the concrete slab 3, covering the top and bottom of the concrete slab 3. While wrapping, rotate the positioning bolt 45 so that the end of the positioning bolt 45 is in close contact with the surface of the support rail 2, and fix the connecting clamping plate 41. Then move the second concrete plate 3 to the right side of the first concrete plate 3, and make the alignment protrusion 9 engage in the inner cavity of the alignment concave surface 10. At this time, the joint of the two concrete plates 3 is wrapped in the inner cavity of the connecting clamping plate 41. Then the user hammers the wedge-shaped sleeper 11 between the concrete plate 3 and the support rail 2, and taps the wedge-shaped sleeper 11 according to the surface flatness of the two concrete plates 3. Under the action of tapping, the wedge-shaped sleeper 11 slides between the support rail 2 and the concrete plate 3, thereby driving the concrete plate 3 at the designated position to move, so as to correct the surface flatness of the two concrete plates 3. Finally, the user uses electric welding equipment to weld the weld 44 through the inner cavity of the welding position 43, so that the support rail 2 and the connecting clamping plate 41 can be stably connected.

[0025] In summary, this autoclaved aerated concrete (AAC) slab installation connector, through the cooperation of the support rail 2 and the expansion sleeve 7, provides an installation platform for the connecting component 4. At the same time, with the cooperation of the connecting component 4, two adjacent concrete slabs 3 can be quickly connected and fixed, thus achieving the purpose of simple and fast connection and stable and reliable connection.
