Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a prefabricated joint structure and construction method for inclined walls. Background Technology

[0002] With societal development, building exterior designs have become increasingly diverse. Among these, sloping walls, often complemented by linear accents and strip windows, enhance the building's dynamism and lighting, leading to their widespread use in construction. Traditionally, sloping walls are constructed by binding reinforcing steel bars to form structural reinforcement, then erecting formwork and pouring concrete. However, this method suffers from difficulties in formwork erection, high construction complexity, slow construction speed, and inconsistent quality. To address these issues, prefabricated construction has emerged. This method involves manufacturing precast concrete wall panels in a factory, pouring a frame with assembly cavities on-site, and then installing the precast concrete wall panels onto the frame. However, this method still has relatively low construction efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a prefabricated joint structure and construction method for inclined walls to solve the problem of low construction efficiency of existing prefabricated concrete inclined wall panels in buildings.

[0004] In a first aspect, the present invention provides a prefabricated joint structure for inclined walls, applied between two floor beams spaced apart along a vertical direction, the prefabricated joint structure comprising:

[0005] The steel structure includes a first structural column, a second structural column, and a first structural beam. The two ends of the first structural column are respectively connected to two floor beams. The bottom end of the second structural column is connected to the floor beam below. The second structural columns are arranged horizontally at intervals on one side of the first structural column. The first structural beam is welded and fixed between the first structural column and the second structural column. The first structural beam extends gradually closer to the first structural column in the horizontal direction and gradually tilts upward in the vertical direction. The first structural column, the second structural column, the first structural beam, and the floor beam below form a trapezoidal first mounting cavity.

[0007] According to the prefabricated joint structure of the inclined wall according to the present invention, it has at least the following beneficial effects:

[0008] By separately configuring the first structural column, second structural column, first structural beam, and first AAC wall panel, standardized prefabrication can be carried out independently in the factory.

Simultaneously, during transportation to the construction site, the first structural column, second structural column, and first structural beam can be assembled and fixed to the designated positions on the floor beams according to the design drawings, forming a first installation cavity with high dimensional accuracy. This ensures that the first AAC wall panel can be embedded within the first installation cavity. The first and second connecting components are then used to fix the first structural beam and the floor beam below, respectively, enabling precise and rapid assembly of the inclined first AAC wall panel onto two vertically spaced floor beams. The entire construction process eliminates the need for concrete pouring, significantly shortening the construction period, effectively improving construction efficiency, and reducing construction difficulty.

[0057] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0058] According to a first aspect of the present invention, a prefabricated joint structure for inclined walls is provided, which is applied between two floor beams 100 spaced apart in a vertical direction. The prefabricated joint structure includes a steel structure and a first AAC wall panel 300. The steel structure includes a first structural column 210, a second structural column 220, and a first structural beam 230. The two ends of the first structural column 210 are respectively connected to the two floor beams 100. The bottom end of the second structural column 220 is connected to the floor beam 100 located below. The second structural column 220 is spaced apart in a horizontal direction on one side of the first structural column 210. The first structural beam 230 is welded and fixed to the first structural column 210. Between the first structural column 210 and the second structural column 220, the first structural beam 230 extends gradually closer to the first structural column 210 in the horizontal direction and gradually tilts upward in the vertical direction. The first structural column 210, the second structural column 220, the first structural beam 230 and the floor beam 100 located below form a trapezoidal first mounting cavity. The first AAC wall panel 300 is embedded in the first mounting cavity. The top end of the first AAC wall panel 300 is fixed to the first structural beam 230 by a first connecting component, and the bottom end of the first AAC wall panel 300 is fixed to the floor beam 100 located below by a second connecting component.

[0059] The prefabricated node structure of this embodiment separates the first structural column 210, the second structural column 220, the first structural beam 230, and the first AAC wall panel 300, allowing for standardized prefabrication in a factory. During mass production, advanced equipment and a rigorous quality control system ensure the quality of each component, reducing errors and uncertainties during on-site construction. Simultaneously, during transport to the construction site, the first structural column 210, the second structural column 220, and the first structural beam 230 can be assembled and fixed to the designated positions on the floor beam 100 according to the design drawings, forming a first installation cavity with high dimensional accuracy. This ensures that the first AAC wall panel 300 can be embedded within the first installation cavity. The first connecting component and the second connecting component are then used to fix the first structural beam 230 and the floor beam 100 below it, respectively. This allows for precise and rapid assembly of the inclined first AAC wall panel 300 onto two vertically spaced floor beams 100. The entire construction process eliminates the need for concrete pouring, significantly shortening the construction period and effectively improving construction efficiency and reducing construction difficulty.

[0060] It should be noted that in this embodiment, the two ends of the first structural column 210 are fixed to the two floor beams 100 respectively, which makes the steel structure more stable under stress and ensures the reliability of the connection between the inclined first AAC wall panel 300 and the two spaced floor beams 100 through the steel structure assembly.

[0061] It is understandable that after the first AAC wall panel 300 is installed in the first mounting cavity, the top surface of the first AAC wall panel 300 is set parallel to the first structural beam 230.

[0062] like Figure 1 As shown, in some embodiments, the steel structure further includes a third structural column 240, which is located between the first structural column 210 and the second structural column 220. The bottom end of the third structural column 240 is connected to the floor beam 100 located below, and the top end of the third structural column 240 is welded and fixed to the first structural beam 230. The third structural column 240 is used to divide the first mounting cavity into a first cavity and a second cavity. The first AAC wall panel 300 includes a first inclined wall portion 310 and a second inclined wall portion 320 that are separately arranged. The first inclined wall portion 310 is embedded in the first cavity, and the second inclined wall portion 320 is embedded in the second cavity. By adding a third structural column 240, the first installation cavity is divided into two parts, so that the first AAC wall panel 300 is disassembled into two separate inclined wall parts 310 and 320, which further achieves lightweighting, reduces assembly difficulty, and eliminates the need for heavy-duty hoisting equipment, so that the first inclined wall parts 310 and 320 can be assembled, thus improving construction accuracy.

[0063] In the specific construction process, the two ends of the first structural beam 230 are first welded and fixed between the first structural column 210 and the second structural column 220. Then, the third structural column 240 is installed between the first structural beam 230 and the floor slab beam below to form the first cavity and the second cavity. Then, the first inclined wall 310 and the second inclined wall 320 are respectively assembled into the first cavity and the second cavity.

[0064] It should be noted that the top ends of the first inclined wall portion 310 and the second inclined wall portion 320 are both fixed to the first structural beam 230 by the first connecting component, and the bottom ends of the first inclined wall portion 310 and the second inclined wall portion 320 are both fixed to the floor beam 100 located below by the second connecting component.

[0065] Specifically, a first slanted window 400 is provided at the top of the first structural beam 230, and the steel structure also includes at least two first hanging columns 250. The projection of the multiple first hanging columns 250 in the vertical direction falls within the range of the first structural beam 230. The top of the first hanging column 250 is connected to the floor beam 100 located above. A second hanging beam 251 is welded and fixed to the bottom of the first hanging column 250, and the top of the first slanted window 400 is welded and fixed to the second hanging beam 251. With this configuration, a first hanging column 250 is fixedly connected to the upper floor beam 100 at the position corresponding to the first structural beam 230. The first hanging column 250 is spaced apart directly above the first structural beam 230, and a second hanging beam 251 is welded between the bottom ends of the first hanging column 250, so that an installation space is formed between the second hanging beam 251 and the first structural beam 230 in the vertical direction, so that the first slanted window 400 can be embedded in the installation space. The bottom end and top end of the first slanted window 400 are welded and fixed to the first structural beam 230 and the second hanging beam 251, respectively. This realizes the assembly of the first slanted window 400 between the two spaced floor beams 100 by steel structure, and ensures the reliability of the installation of the first slanted window 400.

[0066] Specifically, considering that the second hanging beam 251 is set parallel to the horizontal direction and the first structural beam 230 is set at an angle, the projection of the second hanging beam 251 along the horizontal direction falls within the range of the first structural beam 230. In order to improve the connection strength of the steel structure, the end of the second hanging beam 251 facing the first structural beam 230 along the horizontal direction is welded and fixed to the first structural beam 230.

[0067] In specific applications, if the first slanted window 400 is long in the horizontal direction and extends beyond the first structural beam 230, then supporting steel columns are provided between the bottom end of the portion of the first slanted window 400 extending beyond the first structural beam 230 and the floor beam 100 below it, and between the top end of the portion of the first slanted window 400 extending beyond the first structural beam 230 and the floor beam 100 above it.

[0068] It should be noted that both the first structural column 210 and the second structural column 220 are set parallel to the vertical direction.

[0069] In practical applications, the cross-sections of each component of the steel structure are set to rectangles. Specifically, the first structural column 210, the second structural column 220, and the first structural beam 230 are all set to steel square tubes.

[0070] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the second connecting assembly includes a first angle steel 510 and a second hook bolt 530. The first angle steel 510 is connected to the floor beam 100 located below by an expansion bolt 520. The second hook bolt 530 is connected to the opposite bottom end of the first AAC wall panel 300, and one end of the second hook bolt 530 extends outside the first AAC wall panel 300 and is welded to the first angle steel 510. With this setup, during the factory production of the first AAC wall panel 300, holes for fixing the second hook bolt 530 are reserved at the designated positions on the first AAC wall panel 300. This ensures the positional accuracy of the second hook bolt 530 connected to the first AAC wall panel 300, which helps reduce errors and uncertainties during on-site construction. During on-site construction, the first angle steel 510 is first fixed to the floor beam 100 below, corresponding to the first mounting cavity, using expansion bolts 520. The second hook bolt 530 is then welded to the designated position of the first angle steel 510. Subsequently, the first AAC wall panel 300 is embedded in the first mounting cavity, and the second hook bolt 530 is connected and fixed to the corresponding holes at the bottom of the first AAC wall panel 300. This achieves a connection method combining bolts and welding to fix the first AAC wall panel 300 to the floor beam 100 below, which is simple to operate and has strong installation reliability.

[0071] like Figure 2 and Figure 3 As shown, specifically, the first connecting assembly includes a first hook bolt 540, which is connected to the opposite top end of the first AAC wall panel 300. One end of the first hook bolt 540 extends outside the first AAC wall panel 300 and is welded to the first structural beam 230. With this setup, during the factory production of the first AAC wall panel 300, holes for fixing the first hook bolt 540 are reserved at the designated positions on the first AAC wall panel 300. This ensures the positional accuracy of the first hook bolt 540 connected to the first AAC wall panel 300, which helps reduce errors and uncertainties during on-site construction. During on-site construction, the first hook bolt 540 is first welded and fixed to the designated position on the first structural beam 230. Then, the first AAC wall panel 300 is embedded in the first installation cavity, and the first hook bolt 540 is connected and fixed to the corresponding holes at the opposite top of the first AAC wall panel 300. This achieves a connection method combining bolts and welding to fix the first AAC wall panel 300 and the first structural beam 230 together. The operation is simple and the installation is highly reliable.

[0072] In practical applications, the second hook bolt 530 and the first hook bolt 540 are set to be the same hook bolt, which reduces the types of hook bolts, facilitates procurement, avoids confusion, and facilitates on-site construction.

[0073] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the top end of the first structural column 210 is fixed to the upper floor beam 100 by a third connecting assembly. The third connecting assembly includes a first embedded steel bar 610 and a first embedded pad 620. The first embedded steel bar 610 is embedded in the upper floor beam 100. The first embedded pad 620 is embedded in the upper floor beam 100. One side of the first embedded pad 620 is welded to the first embedded steel bar 610, and the side of the first embedded pad 620 facing away from the first embedded steel bar 610 is flush with the side of the upper floor beam 100. The top sidewall of the first structural column 210 is welded and fixed to the first embedded pad 620. During the concrete pouring stage of the upper floor beam 100, the first embedded steel bar 610 is first connected to the steel mesh of the upper floor beam 100. This ensures that the first embedded plate 620 is not prone to displacement during the synchronous pouring of the first embedded pad 620 and the upper floor beam 100. This ensures that after the pouring is completed, the side of the first embedded plate 620 is flush with the side of the upper floor beam 100, effectively avoiding concave and convex phenomena. This facilitates the fixed connection of the top side wall of the first structural column 210 to the first embedded plate 620 using fillet welds. This allows the top of the first structural column 210 to be precisely fixed in the set position of the upper floor beam 100 using an assembled connection method, which helps to shorten the construction period and reduce the construction difficulty.

[0074] In specific applications, the first hanging column 250 is also fixed to the floor beam 100 located above using the third connecting component.

[0075] like Figure 1 and Figure 7As shown, in some embodiments, the bottom end of the first structural column 210 is fixed to the floor beam 100 below by a fourth connecting component. The fourth connecting component includes a second embedded pad 710 and a second embedded steel bar 720. The second embedded pad 710 is embedded in the floor beam 100 below, and the top surface of the second embedded pad 710 is flush with the top surface of the floor beam 100 below. The second embedded steel bar 720 is embedded in the floor beam 100 below and is connected to the bottom end of the second embedded pad 710. With this setup, during the concrete pouring stage of the lower floor beam 100, the second embedded steel bar 720 is first connected to the steel mesh of the lower floor beam 100. This ensures that during the simultaneous pouring of the second embedded pad 710 and the lower floor beam 100, the second embedded pad 710 is less likely to shift. This ensures that after the pouring is completed, the top surface of the second embedded pad 710 is flush with the top surface of the lower floor beam 100, effectively preventing any concave or convex phenomena. This facilitates the fixed connection of the bottom surface of the first structural column 210 to the second embedded pad 710 using fillet welds. This allows the bottom of the first structural column 210 to be precisely fixed to the designated position of the lower floor beam 100 using an assembly connection, which helps to shorten the construction period and reduce construction difficulty.

[0076] In practical applications, both the second structural column 220 and the third structural column 240 are fixed to the floor beam 100 located below using the fourth connecting component.

[0077] like Figure 3 As shown, in some embodiments, sealant 330 is provided between the first AAC wall panel 300 and the first structural column 210, between the first AAC wall panel 300 and the second structural column 220, and between the first AAC wall panel 300 and the first structural beam 230. With this arrangement, after the first AAC wall panel 300 is embedded in the first mounting cavity and fixed to the first structural beam 230 and the floor beam 100 below by the first connecting component and the second connecting component respectively, the sealant 330 is used to fill the gaps between the first AAC wall panel 300 and the first structural column 210, the gap between the first AAC wall panel 300 and the second structural column 220, and the gap between the first AAC wall panel 300 and the first structural beam 230. This not only improves the reliability of the first AAC wall panel 300 in the first mounting cavity, but also facilitates subsequent decoration work.

[0078] like Figure 4As shown, specifically, a mortar layer 340 is provided between the first AAC wall panel 300 and the floor beam 100 below it. With this arrangement, after the first AAC wall panel 300 is embedded in the first mounting cavity and fixed to the first structural beam 230 and the floor beam 100 below it via the first connecting component and the second connecting component, mortar is poured into the gap between the first AAC wall panel 300 and the floor beam 100 below it. After the mortar solidifies, a mortar layer 340 is formed, thus fixing the first AAC wall panel 300 and the floor beam 100 below it together. This improves the reliability of the first AAC wall panel 300 assembled in the first mounting cavity and facilitates subsequent decoration work.

[0079] like Figure 1 As shown, in some embodiments, the steel structure further includes a second hanging column 260, the top of which is connected to the upper floor beam 100. The second hanging column 260 is spaced apart from the first structural column 210 on the side facing away from the second structural column 220 in the horizontal direction. A first hanging beam 270 is welded and fixed between the second hanging column 260 and the first structural column 210. The first hanging beam 270 extends gradually closer to the first structural column 210 in the horizontal direction and gradually slopes downward in the vertical direction. The first structural column 210, the second hanging column 260, the first hanging beam 270 and the upper floor beam 100 form a trapezoidal second mounting cavity. A second AAC wall panel 800 is embedded in the second mounting cavity. The top of the second AAC wall panel 800 is fixed to the upper floor beam 100 by a fifth connecting component, and the bottom of the second AAC wall panel 800 is fixed to the first hanging beam 270 by a sixth connecting component. By using this configuration, the first structural column 210, which is fixed at both ends to the two floor beams 100 respectively, serves as the framework for assembling and fixing the first AAC wall panel 300 and the second AAC wall panel 800. This simplifies the composition of the steel structure while ensuring the reliability of the connection between the inclined first AAC wall panel 300 and the second AAC wall panel 800 and the steel structure assembly between the two spaced floor beams 100. This reduces the space occupied by the steel structure assembly and lowers the construction difficulty.

[0080] It should be noted that by separately setting up the first structural column 210, the second hanging column 260, the first hanging beam 270, and the second AAC wall panel 800, they can be prefabricated independently in a standardized manner in the factory. During the mass production process in the factory, advanced equipment and a strict quality control system are used to ensure the quality of each component, reducing errors and uncertainties in on-site construction. At the same time, during the construction process at the construction site, the first structural column 210, the second hanging column 260, and the first hanging beam 270 can be fixed to the designated positions of the floor beam 100 according to the design drawings, forming a second installation cavity with high dimensional accuracy. This ensures that the second AAC wall panel 800 can be embedded in the second installation cavity, and is fixed to the floor beam 100 and the first hanging beam 270 above by the fifth and sixth connecting components, respectively. This allows for the precise and rapid assembly of the inclined second AAC wall panel 800 between two floor beams 100 that are spaced apart in the vertical direction. The entire construction process does not require concrete pouring, which greatly shortens the construction period, effectively improves construction efficiency, and reduces construction difficulty.

[0081] It is understandable that after the second AAC wall panel 800 is installed in the second mounting cavity, the bottom surface of the second AAC wall panel 800 is set parallel to the first hanging beam 270.

[0082] It should be noted that AAC wall panels refer to autoclaved aerated concrete panels. The first AAC wall panel 300 and the second AAC wall panel 800 need to be laid out and detailed in advance and cut in the factory to ensure that the first AAC wall panel 300 matches the first installation cavity and that the second AAC wall panel 800 matches the second installation cavity. This eliminates the need to cut and remove excess material from the first AAC wall panel 300 and the second AAC wall panel 800 on the construction site, which helps to improve the construction speed.

[0083] like Figure 1As shown, specifically, the steel structure also includes a third hanging column 280, which is located between the first structural column 210 and the second hanging column 260. The top end of the third hanging column 280 is connected to the upper floor beam 100, and the bottom end of the third hanging column 280 is welded and fixed to the first hanging beam 270. The third hanging column 280 is used to divide the second mounting cavity into a third cavity and a fourth cavity. The second AAC wall panel 800 includes a third inclined wall portion 810 and a fourth inclined wall portion 820 that are separately arranged. The third inclined wall portion 810 is embedded in the third cavity, and the fourth inclined wall portion 820 is embedded in the fourth cavity. By adding a third hanging column 280, the second installation cavity is divided into two parts, so that the second AAC wall panel 800 is disassembled into two separate third inclined wall parts 810 and fourth inclined wall parts 820, which further achieves weight reduction, reduces assembly difficulty, and eliminates the need for heavy-duty hoisting equipment, so that the third inclined wall parts 810 and fourth inclined wall parts 820 can be assembled, improving construction accuracy.

[0084] During the specific construction process, the two ends of the first hanging beam 270 are first welded and fixed between the first structural column 210 and the second hanging column 260. Then, the third hanging column 280 is installed between the first hanging beam 270 and the floor beam above it to form the third cavity and the fourth cavity. Then, the third inclined wall part 810 and the fourth inclined wall part 820 are respectively assembled into the third cavity and the fourth cavity.

[0085] It should be noted that the top ends of the third inclined wall section 810 and the fourth inclined wall section 820 are both fixed to the floor beam 100 located above by the fifth connecting component, and the bottom ends of the third inclined wall section 810 and the fourth inclined wall section 820 are both fixed to the first hanging beam 270 by the sixth connecting component.

[0086] like Figure 1As shown, specifically, a second slanted window 900 is provided at the bottom end of the first hanging beam 270. The steel structure also includes at least one fourth structural column 290. The projection of the fourth structural column 290 in the vertical direction falls within the range of the first hanging beam 270. The bottom end of the fourth structural column 290 is connected to the floor beam 100 located below. A second structural beam 291 is welded and fixed to the top end of the fourth structural column 290. The bottom end of the second slanted window 900 is welded and fixed to the second structural beam 291. With this configuration, a fourth structural column 290 is fixedly connected to the floor beam 100 below, corresponding to the first hanging beam 270. The fourth structural column 290 is spaced apart directly below the first hanging beam 270, and a second structural beam 291 is welded to the top of the fourth structural column 290, so that an installation space is formed between the second structural beam 291 and the first hanging beam 270 in the vertical direction, so that the second slanted window 900 can be embedded in the installation space. The bottom and top of the first slanted window 400 are welded and fixed to the second structural beam 291 and the first hanging beam 270 respectively. This allows the second slanted window 900 to be assembled between the two spaced floor beams 100 through a steel structure, and ensures the reliability of the installation of the second slanted window 900.

[0087] Specifically, considering that the second structural beam 291 is set parallel to the horizontal direction, and the projection of the second structural beam 291 along the horizontal direction falls within the range of the first structural column 210, in order to improve the connection strength of the steel structure, the end of the second structural beam 291 facing the first structural beam 230 along the horizontal direction is welded and fixed to the first structural column 210.

[0088] In specific applications, if the second slanted window 900 is long in the horizontal direction and extends beyond the first hanging beam 270, then supporting steel columns are provided between the bottom end of the part of the second slanted window 900 extending beyond the first hanging beam 270 and the floor beam 100 below it, and between the top end of the part of the second slanted window 900 extending beyond the first hanging beam 270 and the floor beam 100 above it.

[0089] It should be noted that all structural columns and hanging columns are set parallel to the vertical direction.

[0090] In practical applications, the cross-sections of each structural column, each hanging column, and the first hanging beam 270 are all set to rectangular. Specifically, the cross-sections of each structural column, each hanging column, and the first hanging beam 270 are all set to steel square tubes.

[0091] Specifically, the second hanging column 260 and the third hanging column 280 are fixed to the upper floor beam 100 using a third connecting assembly.

[0092] Specifically, the fourth structural column 290 is fixed to the floor beam 100 located below it using a fourth connecting component.

[0093] In some embodiments, the fifth connecting assembly includes a second angle steel and a third hook bolt, the second angle steel being connected to the upper floor beam 100 by expansion bolts 520; the third hook bolt being connected to the opposite top end of the second AAC wall panel 800, one end of the third hook bolt extending outside the second AAC wall panel 800 and welded to the second angle steel. By setting it up in this way, during the factory production of the second AAC wall panel 800, holes for fixing the third hook bolt are reserved at the designated position of the second AAC wall panel 800. This ensures the positional accuracy of the third hook bolt connection to the second AAC wall panel 800, which helps to reduce errors and uncertainties during on-site construction. During construction on-site, the second angle steel is first fixed to the position of the upper floor beam 100 corresponding to the second mounting cavity using expansion bolts 520. The third hook bolt is then welded and fixed to the designated position of the second angle steel. Subsequently, the second AAC wall panel 800 is embedded in the second mounting cavity, and the third hook bolt is connected and fixed to the corresponding hole at the opposite top of the second AAC wall panel 800. This achieves a connection method that combines bolts and welding to fix the second AAC wall panel 800 to the upper floor beam 100. The operation is simple and the installation is highly reliable.

[0094] Specifically, the sixth connecting component includes a fourth hook bolt, which is connected to the opposite bottom end of the second AAC wall panel 800. One end of the fourth hook bolt extends outside the second AAC wall panel 800 and is welded to the first lifting beam 270. This arrangement ensures that during the factory production of the second AAC wall panel 800, holes for fixing the fourth hook bolt are pre-drilled at designated positions on the second AAC wall panel 800, guaranteeing the positional accuracy of the fourth hook bolt connection to the second AAC wall panel 800 and reducing errors and uncertainties during on-site construction. During on-site construction, the fourth hook bolt is first welded and fixed to the designated position on the first lifting beam 270. Then, the second AAC wall panel 800 is embedded in the second mounting cavity, and the fourth hook bolt is connected and fixed to the corresponding holes at the opposite bottom end of the second AAC wall panel 800. This achieves a connection method combining bolts and welding to fix the second AAC wall panel 800 and the first lifting beam 270 together, simplifying the operation and ensuring reliable installation.

[0095] In practical applications, the second hook bolt 530, the third hook bolt, and the fourth hook bolt are set to be the same hook bolt, which reduces the types of hook bolts, facilitates procurement, avoids confusion, and facilitates on-site construction.

[0096] like Figure 2As shown, in some embodiments, the thickness of the first AAC wall panel 300 is the same as the thickness of the first mounting cavity. This arrangement ensures that the sidewalls of the first AAC wall panel 300 are flush with the sidewalls of the first structural column 210, the second structural column 220, and the first structural beam 230, guaranteeing high surface flatness at each connection node and improving the subsequent decorative finishing effect.

[0097] Specifically, the thickness of the second AAC wall panel 800 is the same as the thickness of the second mounting cavity. This arrangement ensures that the sidewalls of the first AAC wall panel 300 are flush with the sidewalls of the first structural column 210, the second hanging column 260, and the first hanging beam 270, guaranteeing high surface flatness at each connection node and improving the subsequent decorative finishing effect.

[0098] like Figures 1 to 7 As shown, according to a second aspect of the present invention, a construction method is also provided, applied to constructing the inclined wall prefabricated node structure provided in the first aspect of the present invention between two vertically spaced floor beams 100. The construction method includes the following steps:

[0099] The first structural column 210, the second structural column 220, the first structural beam 230 and the first AAC wall panel 300 are prefabricated in the factory and transported to the construction site.

[0100] According to the design drawings, determine the installation position of the first structural column 210 on the two floor beams 100, fix the bottom end of the first structural column 210 to the floor beam 100 below, and fix the top end of the first structural column 210 to the floor beam 100 above.

[0101] According to the design drawings, determine the installation position of the second structural column 220 on the floor beam 100 below, and fix the bottom end of the second structural column 220 to the floor beam 100 below.

[0102] According to the design drawings, the installation position of the first structural beam 230 is determined on the first structural column 210 and the second structural column 220. The two ends of the first structural beam 230 are welded and fixed to the first structural column 210 and the second structural column 220 respectively, forming the first installation cavity.

[0103] The first AAC wall panel 300 is embedded in the first mounting cavity, and the top end of the first AAC wall panel 300 is fixedly connected to the first structural beam 230 by the first connecting component, and the bottom end of the first AAC wall panel 300 is fixedly connected to the floor beam 100 located below by the second connecting component.

[0104] The construction method of this embodiment separates the first structural column 210, the second structural column 220, the first structural beam 230, and the first AAC wall panel 300, allowing for standardized prefabrication in a factory. During mass production in the factory, advanced equipment and a strict quality control system ensure the quality of each component, reducing errors and uncertainties during on-site construction. Simultaneously, during transportation to the construction site, the first structural column 210, the second structural column 220, and the first structural beam 230 can be assembled and fixed to the designated positions on the floor beam 100 according to the design drawings, forming a first installation cavity with high dimensional accuracy. This ensures that the first AAC wall panel 300 can be embedded within the first installation cavity. The first connecting component and the second connecting component are then used to fix the first structural beam 230 and the floor beam 100 below it, respectively. This allows for precise and rapid assembly of the inclined first AAC wall panel 300 onto two vertically spaced floor beams 100. The entire construction process eliminates the need for concrete pouring, significantly shortening the construction period, effectively improving construction efficiency, and reducing construction difficulty.

[0105] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
