Description

Technical Field

[0001] This utility model relates to the field of hollow wall panel technology, and in particular to an arched pull-type reinforcement for openings in autoclaved aerated concrete hollow wall panels. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a porous thermal insulation wall material made primarily from calcareous and siliceous materials, incorporating a foaming agent, and undergoing a series of processes including casting, static curing, and autoclaving. AAC hollow wall panels are widely used as interior infill walls in various types of buildings.

[0003] In the construction process, aerated concrete hollow slabs are often used to construct walls. However, in practical applications, due to the need to install electrical boxes or other equipment, it is often necessary to make openings in the walls. The making of these openings will disrupt the continuity of the slabs, weakening the overall structure of the wall. Due to the presence of openings, the wall cross-section is no longer complete, making stress concentration more likely to occur at the edges of the openings. This stress concentration may cause cracks in the wall, leading to safety risks and potential hazards in use. In addition, cracks in the wall not only affect the aesthetics of the building but also cause visual discomfort to users, further impacting their experience and overall satisfaction with the building. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of openings in autoclaved aerated concrete hollow slab walls due to the need for electrical boxes, which disrupts the continuity of the slabs, weakens the wall cross section, causes stress concentration at the edge of the opening, and leads to wall cracks and other safety and usage risks. To address this, we propose an arched pull-clip reinforcement for openings in autoclaved aerated concrete hollow wall panels.

[0005] To achieve the above objectives, this application adopts the following technical solution: an arched pull-and-clip reinforcement for openings in autoclaved aerated concrete (AAC) hollow wall panels, comprising an AAC hollow wall panel body, a square hole at one end of the AAC hollow wall panel body, two C-shaped steels installed inside the square hole, multiple cavities inside the AAC hollow wall panel body, multiple holes on one side of the C-shaped steels, a screw rod slidably connected inside the holes, a bolt fixedly connected to one side of the screw rod, a flat washer slidably connected to the surface of the screw rod, an arched toothed steel clamping plate slidably connected to the surface of the screw rod, a round hole at one end of the arched toothed steel clamping plate, and a nut fixedly connected to the other end of the arched toothed steel clamping plate for threaded connection with the screw rod.

[0006] Preferably, the overall height of the C-shaped steel is the same as the height of the square hole, and the width of the C-shaped steel is the same as the width of the square hole.

[0007] Preferably, the diameter of the hole is adapted to the screw rod, the diameter of the round hole is adapted to the screw rod, and the diameter of the nut is adapted to the screw rod.

[0008] Preferably, the length of the screw is not greater than three-quarters of the cavity diameter, the height of the arched toothed steel plate is not greater than one-half of the cavity diameter, and the width of the arched toothed steel plate is not less than one-half of the cavity diameter.

[0009] Preferably, the arched toothed steel plate has toothed toes at both ends, with a tooth height of three to five millimeters and a tooth pitch of three to five millimeters.

[0010] Preferably, the arched toothed steel plate is made of high-strength steel.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention solves the problem of reinforcing openings in autoclaved aerated concrete (AAC) hollow wall panels. The overall structural components can be installed according to the actual on-site construction conditions, resulting in fast construction speed. This reinforcement method fully utilizes the force-bearing principle of arches, saving materials. The arched toothed steel clamps and C-shaped steel can be prefabricated in factories, resulting in a high degree of industrialization, low cost, and reliable quality of each component. The unidirectional tensile force generated by the combination of the arched toothed steel clamps and C-shaped steel can give the AAC hollow wall a better overall integrity and a good reinforcement effect. The interlocking force between the teeth of the arched toothed steel clamps and the inner wall of the hollow opening can generate a greater unidirectional tensile force between the steel clamps and the C-shaped steel.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an arched pull-and-clip reinforcement for openings in autoclaved aerated concrete (AAC) hollow wall panels, comprising an AAC hollow wall panel body 1, a square hole 11 at one end of the AAC hollow wall panel body 1, two C-shaped steels 2 installed inside the square hole 11, multiple cavities 3 inside the AAC hollow wall panel body 1, multiple holes 4 on one side of the C-shaped steels 2, a screw 5 slidably connected inside the holes 4, a bolt 6 fixedly connected to one side of the screw 5, a flat washer 10 slidably connected to the surface of the screw 5, and an arched toothed steel clamp 7 slidably connected to the surface of the screw 5, a round hole 8 at one end of the arched toothed steel clamp 7, and a nut 9 fixedly connected to the other end of the arched toothed steel clamp 7 for threaded connection with the screw 5, the overall height of the C-shaped steels 2 being the same as the height of the square hole 11, and the width of the C-shaped steels 2 being the same as the width of the square hole 11. First, the screw 5 is inserted into the flat washer. Ring 10, then pass it through the hole 4 on one side of the C-shaped steel 2, with the flange of the C-shaped steel 2 facing the far end of the screw 5. Then, pass the far end of the screw 5, which has already been fitted with the flat washer 10 and the C-shaped steel 2, through the nut 9 at one end of the arched toothed steel clamp 7 from the inside out. Next, align the C-shaped steel 2 with the autoclaved aerated concrete hollow wall panel body 1, and rotate the arched toothed steel clamp 7 until its long side is parallel to the length of the cavity 3. Then, place the arched toothed steel clamp 7 into the cut cavity 3, and finally, clockwise... Bolt 6 and screw 5 drive the arched toothed steel clamp 7 to rotate. As screw 5 tightens, the arched toothed steel clamp 7 is inserted into the inner wall of cavity 3 through its teeth and is locked in place. The arched toothed steel clamp 7 provides a reaction force perpendicular to the cavity wall through deformation along the arch height direction to fix the arched toothed steel clamp 7, and provides a reaction force tangential to the cavity wall to provide tension for fastening C-shaped steel 2. In this way, bolt 6 can make C-shaped steel 2 and autoclaved aerated concrete hollow wall panel body 1 tensile and bonded together and fastened, thus completing the reinforcement.

[0021] Reference Figure 2 , Figure 4 and Figure 5As shown in this embodiment: the diameter of hole 4 is adapted to that of screw 5, the diameter of round hole 8 is adapted to that of screw 5, and the diameter of nut 9 is adapted to that of screw 5. Through the precise matching hole diameter design, a tight connection between screw 5 and hole 4, round hole 8, and nut 9 is ensured, thereby improving the stability and load-bearing capacity of the overall structure, reducing the reliance on professional installation tools, and making construction more convenient and efficient. Due to the compatibility of screw 5 with the hole diameters of each component, loosening caused by vibration or external force during use can be effectively prevented, enhancing the durability of the structure.

[0022] Reference Figure 3 and Figure 4 As shown in this embodiment: the length of the screw 5 is no greater than three-quarters of the diameter of the cavity 3; the height of the arched toothed steel clamp 7 is no greater than half the diameter of the cavity 3; and the width of the arched toothed steel clamp 7 is no less than half the diameter of the cavity 3. The length of the screw 5 is designed to be less than three-quarters of the diameter of the cavity 3, ensuring that the screw 5 has sufficient space to rotate during tightening, while avoiding structural damage caused by excessive insertion. The height of the arched toothed steel clamp 7 does not exceed half the diameter of the cavity 3. This height design ensures that the arched toothed steel clamp 7 can be effectively embedded in the inner wall of the cavity 3, while avoiding excessive occupation of the space in the cavity 3, thus not affecting the installation of other structural components. The width of the arched toothed steel clamp 7 is no less than half the diameter of the cavity 3. This width design ensures that the arched toothed steel clamp 7 has sufficient contact area in the cavity 3, thereby providing sufficient tensile strength and stability, and ensuring a tight bond between the C-shaped steel 2 and the autoclaved aerated concrete hollow wall panel body 1.

[0023] Reference Figure 4 As shown in this embodiment, the arched toothed steel clamp 7 has toothed toes at both ends, with a tooth height of three to five millimeters and a tooth pitch of three to five millimeters. The reasonable setting of tooth height and tooth pitch ensures that the arched toothed steel clamp 7 can effectively bite the C-shaped steel 2 when tension is applied, preventing slippage.

[0024] Reference Figure 4 As shown in this embodiment, the arched toothed steel plate 7 is made of high-strength steel. High-strength steel has high tensile strength and good toughness, and can withstand large tensile forces without breaking. The use of high-strength steel ensures that the arched toothed steel plate 7 is not easily deformed during long-term use, thus maintaining the stability and reliability of the structure.

[0025] The specific steps for using the arched pull-tab reinforcement for openings in autoclaved aerated concrete hollow wall panels are as follows:

[0026] Insert the screw 5 into the flat washer 10, and then pass it through the hole 4 on one side of the C-shaped steel 2, with the flange of the C-shaped steel 2 facing the far end of the screw 5;

[0027] Pass the far end of the screw 5, which has been fitted with the flat washer 10 and the C-shaped steel 2, through the nut 9 at one end of the arched toothed steel clamp 7 from the inside out;

[0028] Next, align the C-shaped steel 2 with the autoclaved aerated concrete hollow wall panel body 1, rotate the arched toothed steel plate 7 so that its long side is parallel to the length of the cavity 3, and place the arched toothed steel plate 7 into the cut cavity 3.

[0029] Finally, the bolts 6 and 5 rotate clockwise, causing the arched toothed steel clamp 7 to rotate. As the bolts 5 tighten, the arched toothed steel clamp 7 is inserted into the inner wall of the cavity 3 through its teeth and is locked in place. The arched toothed steel clamp 7 provides a reaction force perpendicular to the cavity wall through deformation along the arch height direction to fix the arched toothed steel clamp 7, and provides a reaction force tangential to the cavity wall to provide tension for fastening the C-shaped steel 2. In turn, the bolts 6 cause the C-shaped steel 2 and the autoclaved aerated concrete hollow wall panel body 1 to be tensile and bonded together and fastened, thus completing the reinforcement.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
