Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to an ALC panel assembly structure based on structural columns and a connection and installation method. Background Technology

[0002] ALC panels are lightweight precast components made of high-performance autoclaved aerated concrete. They are manufactured in a factory and then transported to the site for installation, primarily used for partitioning interior spaces. ALC panel walls offer advantages such as low weight, easy installation, high construction efficiency, smooth walls, and an aesthetically pleasing appearance, and have been widely adopted.

[0003] Since ALC panels are installed after the main structure is completed, there is a sufficiently large working surface. The typical construction method for ALC panel walls is as follows: first, the wall installation position is marked and lines are drawn; then, steel components such as clamps and steel cages for structural columns are installed on the lower and upper concrete structures; then, the ALC panels are transported to the vicinity of the installation position; and then, auxiliary turning equipment is used to turn the ALC panels 90 degrees before installing them one by one. Finally, formwork is erected and concrete structural columns and other parts are poured.

[0004] One of the major advantages of ALC panel installation is that it can be installed in the confined space of the lower and upper concrete structures. Each ALC panel is lightweight and does not require hoisting equipment.

[0005] However, existing construction and installation methods have revealed significant defects: 1. Although the interlocking of ALC panels and the connection of reinforcing bars can enhance the connection strength to a certain extent, the lack of active restraint in the horizontal direction results in a loosely bonded and poorly integrated wall structure. During use, cracks are prone to occur at the joints. 2. Although ALC panels are not vertical load-bearing structures, they will inevitably be subjected to horizontal static or dynamic forces perpendicular to the wall surface during use. Due to the small contact area between the upper and lower clamps and the ALC panels, and the fact that the autoclaved aerated concrete at the joints is prone to brittle damage, their effectiveness is very limited, and they may even fail, leading to misalignment, cracking, or even collapse of the ALC panel wall. 3. Especially at the corner joints of ALC panels, although structural columns are set according to specifications, the actual overall connection is poor. In engineering, cracking between ALC panels and concrete structural columns is very common.

[0006] To address the aforementioned issues, technicians have developed a patented technology that uses screws to connect and fix ALC panels together to form a unified structure. While this technology effectively improves the overall integrity of ALC panel walls and provides crack prevention, it still has several shortcomings: 1. The screws do not form an effective bond with the ALC panels. With prolonged use, deformation of the screws can cause misalignment, leading to cracks at the joints and insufficient durability; 2. It does not effectively address the connection methods between the ALC panel assemblies and with load-bearing walls; 3. Using screws to connect along the length of the wall consumes a large number of screws, resulting in high costs; 4. It fails to solve the problem of overall structural stability at corner joints of ALC panels, i.e., at structural column locations. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an ALC panel assembly structure and connection and installation method based on structural columns, which can effectively position the ALC panel, and the structural column operation has small disturbance and the overall structure is stable and reliable.

[0008] To solve the above-mentioned technical problems, the present invention provides an ALC panel assembly structure based on structural columns, including adjacent ALC walls set between an upper fixed platform and a lower fixed platform, a structural column set between the two ALC walls, a prefabricated frame set at the top and bottom of the structural column, a steel cage set between the two prefabricated frames, a through hole set inside the ALC wall corresponding to the horizontal direction of the prefabricated frame, the through hole penetrating both ends of the ALC wall in the length direction, and a high-strength steel wire set inside the through hole;

[0009] The prefabricated frame includes a fixed base plate, a vertical plate is provided on the surface of the fixed base plate, a fixed plate is provided on the top of the vertical plate, two steel wire anchors are provided on the fixed plate, and a hollow telescopic limiting component is provided on the surface of the vertical plate corresponding to the through hole;

[0010] The telescopic limiting component is used to press the upright plate against the adjacent ALC wall.

[0011] One end of the high-strength steel wire passes through the hollow telescopic limiting member and is connected to the steel wire anchor, while the other end is fixedly connected to the adjacent load-bearing component.

[0012] The through-hole is filled with grout, which combines the high-strength steel wire with the ALC wall into a single structure.

[0013] Furthermore, the surface of the upright plate is provided with a through hole, and one end of the strong steel wire passes through the hollow telescopic limiting member and the through hole and is connected to the steel wire anchor.

[0014] Furthermore, the fixing plate is inclined and forms a 45-degree angle with the axis of the through hole. A reinforcing plate is provided between the fixing plate and the fixing base plate, and the side of the reinforcing plate is fixedly connected to the surface of the upright plate.

[0015] Furthermore, a force-bearing plate is provided between the reinforcing plate and the surface of the upright plate, and the force-bearing plate forms a 90-degree angle with the axial direction of the adjacent through hole. The hollow telescopic limiting member is fixedly installed on the force-bearing plate.

[0016] Furthermore, the hollow telescopic limiting component includes an external threaded sleeve and an internal threaded sleeve, wherein the internal threaded sleeve is screwed onto the surface of the external threaded sleeve.

[0017] Furthermore, it also includes a hollow top plate, on one side surface of which a sleeve is provided, the sleeve being disposed in a through hole, and the internally threaded sleeve abutting against the hollow top plate and generating a clamping force.

[0018] Furthermore, the surface of the fixed base plate is provided with four mounting pipes, and the ends of the main reinforcing bars of the steel cage are inserted into the corresponding mounting pipes.

[0019] Furthermore, the installation tube is provided with anchoring adhesive.

[0020] Furthermore, grouting holes are provided on the ALC plates in the ALC wall, and the grouting holes are connected to the through holes.

[0021] A method for connecting and installing an ALC board, used for constructing the aforementioned assembly structure, includes the following steps:

[0022] Step 1) Insert high-strength steel wires into the load-bearing components corresponding to the two through holes of each ALC wall section, and install prefabricated frames at the corresponding positions of the structural columns at the corners. The prefabricated frames are fixed with expansion bolts.

[0023] Step 2) Install individual ALC panels in the ALC wall between the upper and lower fixed platforms in sequence, while passing high-strength steel wires through the through holes until all ALC panels on both sides of the ALC wall are installed. The high-strength steel wires are located on one side of the prefabrication frame.

[0024] Step 3) Tension the high-strength steel wire and fix it to the wire anchor on the precast frame;

[0025] Step 4) Extend the telescopic limiting piece and press it against the side of the ALC wall panel to limit the horizontal displacement of a single ALC panel.

[0026] Step 5) Grout the through hole to integrate the high-strength steel wire with the ALC wall panel.

[0027] Step 6) Place the steel reinforcement cage between the two precast frames, set up the formwork, and pour concrete to complete the construction.

[0028] The beneficial effects of this invention are:

[0029] 1. By connecting ALC panels on the same side in series with high-strength steel wires, and with the help of telescopic limiting devices on two prefabricated frames, multiple ALC panels can be effectively limited, resulting in active restraint in the horizontal direction. The resulting wall is tightly connected and has good overall integrity. Since the integral structure can be formed before the construction of the structural columns, the vibration of concrete during the construction of the structural columns will not disturb the ALC panels, and the gap between adjacent ALC panels is effectively controlled.

[0030] 2. High-strength steel wires are used to connect ALC panels on the same side in series and then fixed together with grout. While the upper and lower clamps limit the fixation of the ALC panels, the high-strength steel wires also provide a buffering effect. Even if the positioning components fail and an impact occurs, the ALC panels will not overturn or tip over, ensuring good safety and reliability. The high-strength steel wires also enhance the integrity between adjacent ALC panels in the ALC wall, effectively reducing the occurrence of misalignment and cracking.

[0031] 3. When high-strength steel wire is combined with two precast frames, a stable frame structure can be formed between the structural column and the load-bearing component, effectively reducing cracking problems caused by different materials and deformation. In addition, the ALC wall is also integrated with the load-bearing component and the platform at the frame fixing point through the high-strength steel wire, effectively solving the problem of the overall firmness of the connection between the ALC slab corner and the structural column.

[0032] 4. The setting of two precast frames allows for flexible construction timing of the structural columns, enabling unified pouring of nodes and greatly improving construction convenience.

[0033] 5. The high-strength steel wire has a bendable structure and is tensioned and fixed into a straight structure after all ALC panels are installed. Therefore, while ensuring the overall connection, only the threading spacing needs to be reserved during the installation process, which facilitates the splicing of ALC panels and the operation is not restricted.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0040] Reference Figures 1 to 5 As shown, an embodiment of the ALC panel assembly structure based on structural columns of the present invention is illustrated, wherein the assembly structure is as follows:

[0041] Specifically, an ALC wall 3 is set between and adjacent to the upper fixed platform 1 and the lower fixed platform 2, and the other two sides are load-bearing components 4. A structural column is set between the two ALC walls, i.e. at the corner. The ALC wall is assembled from multiple ALC panels 31 in sequence. The ALC wall has through holes 5 inside, and high-strength steel wires 6 are set in the through holes. The high-strength steel wires are used to tension the structural column and the load-bearing components into one, thereby improving the overall structure's coordinated deformation and load-bearing capacity.

[0042] The aforementioned structural column is formed by casting precast frames 7 at the top and bottom and a steel cage 8 between the two precast frames. The two precast frames are fixedly installed on the upper and lower fixed platforms, respectively. The precast frame includes a fixed base plate 9, and four installation pipes 17 are provided on the surface of the fixed base plate. The ends of the main bars of the steel cage are inserted into the corresponding installation pipes. The fixed base plates on the two precast frames can effectively limit the two ends of the steel cage. The operation is simple. The installation pipes are filled with anchoring adhesive, which can make the steel cage and the precast frame form a whole with connection strength, thereby improving the strength of the structural column. A vertical plate 111 is installed on the surface of the fixed base plate, and a fixed plate 10 is installed on the top of the vertical plate. Two wire anchors 11 are installed on the fixed plate. A hollow telescopic limiting component 12 is installed on the surface of the vertical plate corresponding to the through hole. The hollow telescopic limiting component includes an external threaded sleeve and an internal threaded sleeve. The internal threaded sleeve is screwed onto the surface of the external threaded sleeve, which is convenient to operate and low in cost. Since the structural column is small in size and has two high-strength steel wires that need to be fixed on the same side, the above-mentioned wire anchors are set vertically, and the high-strength steel wires extend horizontally to ensure a large construction space. A through hole is provided on the surface of the vertical plate. One end of the high-strength steel wire passes through the hollow telescopic limiting component and the through hole and connects to the wire anchor. The above-mentioned fixed plate is set at an angle and forms a 45-degree angle with the axis of the through hole to ensure that the high-strength steel wires on both sides can be fully stressed. A reinforcing plate is installed between the fixed plate and the fixed base plate. The side of the reinforcing plate is fixedly connected to the surface of the vertical plate to improve the strength of the fixed plate.

[0043] The telescopic limiting component is used to press the vertical plate against the adjacent ALC wall. After pressing, the distance between the ALC wall and the precast frame is fixed, and the ALC wall is pushed against the load-bearing component to achieve the effect of limiting the horizontal direction. Since the direction of the force applied by the telescopic limiting component is at an angle to the vertical plate, a force-bearing plate is set between the reinforcing plate and the surface of the vertical plate. The force-bearing plate is at a 90-degree angle to the axis of the adjacent through hole. The hollow telescopic limiting component is fixedly set on the force-bearing plate for easy operation and to ensure good strength. During the process of applying pressure by the telescopic limiting component, due to the material of the ALC plate, the side of the ALC plate is easily crushed. Therefore, a hollow top plate 15 is also designed. A sleeve 16 is set on one side surface of the hollow top plate. The sleeve is set in the through hole for easy installation. The internal threaded sleeve abuts against the hollow top plate and generates a pressing force. The force is evenly released to avoid concentrated damage to the side.

[0044] One end of the high-strength steel wire passes through the hollow telescopic limiting component and is connected to the wire anchor, while the other end is fixedly connected to the adjacent load-bearing component. Before being anchored to the steel wire, the high-strength steel wire needs to be tensioned to create tension between the load-bearing component and the precast frame, and to create a good frame structure between the load-bearing component and the structural column. At this time, the stress situation is transferred from the precast frame to the upper and lower fixed platforms. The ALC wall is fixed within a stable frame structure, which can improve the overall effect and avoid the generation of cracks. Grouting material is also injected into the through hole. The grouting material combines the high-strength steel wire and the ALC wall into a whole structure, further improving the integrity. The individual ALC panels are also restricted by the high-strength steel wire, which can greatly improve the overall structural strength and quality. In order to facilitate the grouting construction, grouting holes 18 are opened on the ALC panels in the ALC wall. The grouting holes are connected to the through holes, and the grouting material is directly injected into the through holes through the grouting holes, which can also avoid the blockage of the through holes caused by long-distance grouting.

[0045] The aforementioned high-strength steel wires are arranged in two layers, upper and lower, within the ALC wall. This not only improves the overall structural stability but also restricts the fixing position of the ALC wall, stabilizing it from top to bottom in a "clothes-drying" manner. Even if the fixing components at the top and bottom of the ALC wall fail or an impact occurs, the high-strength steel wires can provide protection and prevent the ALC wall from tilting. Furthermore, after grout is injected into the through holes, the high-strength steel wires can also offset the impact force, greatly improving the overall strength.

[0046] Based on the above structure, this application also provides a method for connecting and installing ALC panels. During the construction process, high-strength steel wires are first inserted into the load-bearing components corresponding to the two through holes of each ALC wall panel to form a fixed point. Then, a prefabricated frame is installed at the structural column position between the two ALC wall panels. The prefabricated frame is fixed with expansion screws. The construction is simple and the installation is convenient, without waiting.

[0047] After the preparation work is completed, the individual ALC panels in the ALC wall panel are installed between the upper fixed platform and the lower fixed platform in sequence. At the same time, the high-strength steel wire is passed through the through hole to install until all the ALC panels of the two ALC wall panels are installed. Finally, the high-strength steel wire passes through the through hole of the last ALC panel and the end is located on the side of the prefabrication frame.

[0048] The high-strength steel wire can then be tensioned and fixed. First, the high-strength steel wire is passed through the hollow telescopic limiter and the steel wire anchor. Then, the high-strength steel wire is tensioned using a hydraulic cylinder. After tensioning, the anchor fixes the high-strength steel wire, so that tension is formed between the precast frame and the load-bearing component. The precast frame will also transfer the force to the corresponding upper and lower fixed platforms, resulting in strong structural stability.

[0049] Then, the telescopic limiting component extends, the internal threaded sleeve is screwed out and pressed against the side of the ALC wall panel. A hole can be made on the surface of the internal threaded sleeve to facilitate rotation and limit the displacement of a single ALC panel in the length direction, that is, to press the ALC wall panel towards the load-bearing component.

[0050] At this point, grouting can be performed inside the through-hole to integrate the high-strength steel wire with the ALC wall panel. After the grout has initially set, the reinforcing cage can be placed between the two precast frames and cast into shape. When placing the reinforcing cage, first place the stirrups on the lower precast frame, overlapping them around the four installation pipes. Then, insert the main reinforcement bars into the lower installation pipes, bend the main reinforcement bars, and insert them into the corresponding upper installation pipes. After the four main reinforcement bars are completed, tie the stirrups in sequence at intervals. To ensure the connection strength between the reinforcing cage and the precast frame, structural adhesive can be placed inside the installation pipes to bond the two together. After the formwork is erected and the concrete is poured, the overall strength of the structural column is guaranteed, and the structural column will not crack or cause other problems.

[0051] Construction was completed after the structural columns were poured and cured.

[0052] Throughout the construction process, after the ALC panels are assembled, they are fixed by the inherent corner brackets and also limited in length by hollow telescopic limiters and restricted by two high-strength steel wires. This effectively reduces the risk of the ALC panels falling off, so the safety is not affected even without the construction of precast columns. As a result, the structural columns can be poured and the through holes can be grouted at any time, allowing for greater flexibility in timing.

[0053] Furthermore, through the combination of high-strength steel wire and precast frame, the structural column also participates in the stress model of the ALC wall on both sides. Specifically, after construction, the precast frame at both ends of the structural column forms a steel core structure at both ends. The steel core structure at both ends can provide the restraining force of the high-strength steel wire before the structural column is poured. The steel core structure can transfer the restraining force to the concrete structure of the structural column, so that the high-strength steel wire, steel core structure and concrete structure form a whole, jointly bearing the tensile, compressive and shear forces that occur during use, thereby effectively suppressing the wall cracking problem and greatly improving the overall strength of the ALC structure.

[0054] The separate design of the two steel core structures allows for independent force application to the two high-strength steel wires. During construction, this facilitates the arrangement of the reinforcing cage and effectively reduces material and construction costs. Furthermore, when subjected to external impacts or other forces, the force on the upper or lower steel core structure is transferred to the other steel core structure through the concrete of the structural column. This transferred force is significantly dissipated within the concrete, minimizing disturbance to the other steel core structure. Therefore, even without overall structural failure, the remaining steel core structure can still function independently, ensuring the stability of the entire structure and preventing complete failure. This reduces the likelihood of overall overturning and improves overall safety.

[0055] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
