Description

Technical Field

[0001] The utility model relates to a building technology, in particular to a combined structure. Background Art

[0002] Currently, there is a significant demand for modular structures, such as portable or mobile ones. These structures typically consist of multiple prefabricated components that fit together to form vertical wall panels and generally horizontal wall panels. On-site, these prefabricated components are assembled and fixed to create a building, house, or other structure that fits the space.

[0003] How to improve the efficiency of connection and fixation between prefabricated parts and ensure the reliability of connection and fixation between prefabricated parts is a technical problem that needs to be solved at present.

[0004] Furthermore, existing technologies already utilize hollow building panels to form buildings. These panels typically have a hollow structure, significantly reducing their weight. Hollow building panels are typically formed by connecting multiple unit components. By varying the number of unit components, the panel can be tailored to the desired area. The structural shape of the unit components not only affects the mechanical properties of the hollow building panel but also the method of connection and fixation between the unit components, which in turn affects the production efficiency of the hollow building panel.

[0005] Therefore, how to improve the production efficiency of hollow building panels while ensuring the mechanical properties of hollow building panels is another important problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] To this end, the utility model provides a modular structure, the prefabricated parts of the vertical wall panels and the flat wall panels of the structure can be more conveniently positioned and fixed, and the reliability of the connection and fixation between the prefabricated parts can be improved.

[0007] The modular structure provided by the utility model includes vertical wall panels and flat wall panels; the upper and lower ends of the vertical wall panels are respectively fixed to a flat wall panel, and further include a Z-shaped connector; the Z-shaped connector includes a flat connecting plate, a vertical connecting plate, a supporting plate, and a limiting plate connected in sequence, and a limiting groove is formed between the vertical connecting plate, the supporting plate, and the limiting plate; the flat connecting plate extends horizontally; the vertical connecting plate extends vertically downward; the supporting plate also extends horizontally, in the opposite direction of the extension direction of the flat connecting plate; and the limiting plate extends vertically upward.

[0008] The end of the vertical wall panel is inserted into the limiting groove, the vertical connecting plate is located between the side wall surface of the flat wall panel and the inner wall surface of the vertical wall panel, and the flat connecting plate is fitted and positioned with the upper surface or the lower surface of the flat wall panel, thereby keeping the end of the vertical wall panel and the flat wall panel fixed.

[0009] In this way, the positioning between the vertical wall panel and the flat wall panel can be achieved through the limiting groove of the Z-shaped connector. At the same time, the vertical wall panel and the Z-shaped connector, combined with the larger area of ​​the flat wall panel, can ensure the relative positioning of the vertical wall panel and the flat wall panel, and ensure the reliability of the relative fixation between the two.

[0010] In a further technical solution, the outer edge of the limiting plate is inclined in a direction away from the vertical connecting plate, which can facilitate the insertion of the end of the vertical wall panel into the limiting groove, achieve rapid positioning, and thus improve assembly efficiency.

[0011] In a further technical solution, the flat connecting plate is fixed to the upper surface or lower surface of the flat wall panel by fasteners; the limiting plate can also be fixed to the surface of the vertical wall panel by fasteners, thereby improving the reliability of the fixing of the vertical wall panel to the flat wall panel.

[0012] A further technical solution also includes an L-shaped connector formed by two connecting side panels; one connecting side panel of the L-shaped connector is attached to and fixed to the flat connecting panel, and the other connecting side panel is attached to and fixed to the surface of the vertical wall panel, thereby keeping the vertical wall panel and the flat wall panel fixed, thereby enhancing the reliability of the fixation of the two.

[0013] In a further technical solution, at least a portion of the vertical wall panels and the horizontal wall panels is a hollow building panel, and the hollow building panel includes a plurality of sequentially arranged unit components, edge unit components, and blocking components; the unit component is formed by bending a complete plate, and may include a first panel portion, a second panel portion, and a core panel;

[0014] The two ends of the core plate are connected to the inner ends of the first panel part and the second panel part through the first connecting folding part and the second connecting folding part respectively; the outer ends of the first panel part and the second panel part are respectively formed with a first sewing flange and a second sewing flange bent inward and inward;

[0015] The first connecting folding portion and the second connecting folding portion of the unit component can respectively include a first bending compound section and a second bending compound section inclined outward; and the first bending compound section and the second bending compound section can respectively correspond to the first sewing flange and the second sewing flange to facilitate the sewing and fixation between the unit components.

[0016] The above-mentioned unit components formed by bending as a whole can be arranged sequentially in the cross-sectional direction, and the first bent composite section of the first unit component is inserted between the first stitched flange of the second unit component and the first panel portion; the second bent composite section of the first unit component is inserted between the second stitched flange of the second unit component and the second panel portion; the first bent composite section of the first unit component is kept in contact with the first stitched flange and the first panel portion of the second unit component, and the second bent composite section of the first unit component is kept in contact with the second stitched flange and the second panel portion of the second unit component, thereby enabling adjacent unit components to be stitched and kept in contact. A plurality of unit components are sequentially connected and fixed in the same manner to form a hollow building panel of appropriate size. By cooperating with the first bent composite section of the first unit component and the first stitched flange of the second unit component, a hollow building panel can be conveniently formed; at the same time, the unit components are sewn and fixed by the first bent composite section of the first unit component and the first stitched flange of the second unit component, and then the first panel portion and the second panel portion are connected by the core panel, while the mechanical properties of the hollow building panel are guaranteed, the production efficiency of the hollow building panel is improved.

[0017] In a further optional technical solution, the first and second panel portions extend in parallel. This ensures that the first and second panel portions are aligned relative to the core panel at the front and rear of the stitched hollow building panel, reducing stress and deformation in the stitched hollow building panel and improving the stability of the panel's structural performance.

[0018] In a further optional technical solution, when forming the unit component, the extension direction of the core plate is perpendicular to the extension direction of the first panel portion. This can fully utilize the supporting function of the core plate and ensure the rigidity and stability of the hollow building panel in the thickness direction.

[0019] In a further reliable technical solution, when forming the unit components, the first and second panel portions are each inclined and extended to opposite sides. This allows the tapered structure formed by the first and second panel portions to be utilized when sewing the unit components together, facilitating the joining of the unit components and further facilitating sewing and fixing. This can improve the production efficiency of hollow building panels and reduce the cost of hollow building panels.

[0020] In a further preferred technical solution, the first connecting folded edge portion and the second connecting folded edge portion further include a first folded accommodating recess and a second folded accommodating recess, respectively; the first folded accommodating recess is connected between the first bending composite section and the first panel portion, and the second folded accommodating recess is connected between the second bending composite section and the second panel portion; the first folded accommodating recess and the second folded accommodating recess respectively form a first folded accommodating groove and a second folded accommodating groove, and accommodate the stitched folded edge; further preferably, the depth of the first folded accommodating groove and the second folded accommodating groove is no less than 4 times the thickness of the sheet material forming the unit component. In this way, the stitched folded edge can be located within the side surfaces of the first and second panel portions, thereby ensuring the flatness of the surface of the hollow building panel and improving the performance of the hollow building panel.

[0021] In an optional technical solution, the first panel portion and the second panel portion are symmetrically arranged, which can ensure that the hollow building panel is flat and avoid deflection.

[0022] In an optional technical solution, the cross-sectional width of the first panel portion is 1.3 to 1.9 times the cross-sectional width of the core panel. This ensures the support provided by the panel portion of the core panel, thereby guaranteeing the strength of the hollow building panel. Furthermore, the cross-sectional widths of the first and second seamed flanges are both greater than one-tenth of the cross-sectional width of the first panel portion, ensuring appropriate connection dimensions between the unit components and, therefore, ensuring reliable connections between the unit components in the hollow building panel.

[0023] In a further preferred technical solution, the first stitched flange of the first unit component is inserted between the first bent composite section and the first folded accommodating recess of the second unit component; the second stitched flange of the first unit component is inserted between the second bent composite section and the second folded accommodating recess of the second unit component; and the first stitched flange of the first unit component is kept in close contact with the first bent composite section and the first folded accommodating recess of the second unit component; and the second stitched flange of the first unit component is kept in close contact with the second bent composite section and the second folded accommodating recess of the second unit component.

[0024] In a further technical solution, the hollow building panel also includes an edge unit component and a blocking structure; the edge unit component is formed by bending a complete plate, and includes a first edge panel portion, a second edge panel portion and an edge core plate; the two ends of the edge core plate are respectively connected to the inner ends of the first edge panel portion and the second edge panel portion by a first edge connecting folding portion and a second edge connecting folding portion; the first edge bending composite section in the edge unit component is inserted between the first stitched flange of the outermost unit component and the first panel portion; the second edge bending composite section in the edge unit component is inserted between the second stitched flange of the outermost unit component and the second panel portion; and the first edge bending composite section of the edge unit component is kept in contact with and fixed to the first stitched flange and the first panel portion of the outermost unit component, and the second edge bending composite section of the edge unit component is kept in contact with and fixed to the second stitched flange and the second panel portion of the outermost unit component;

[0025] The two sides of the blocking member are connected to the first edge panel portion and the second edge panel portion, respectively, to seal the outer edge opening of the edge unit member.

[0041] The following describes the specific embodiments provided by the present invention. The modular structure is first described, and then the unit components of the hollow building panel and the structure of the hollow building panel formed by the unit components are explained.

[0042] Those skilled in the art can understand that in this patent, the unit component is a long strip component, and its main improved structure is reflected in the cross-sectional structure. Therefore, for the convenience of description and for easy understanding, the directional words in this document are mainly determined based on the cross-sectional views shown in the corresponding drawings; similarly, for the convenience of description and for easy understanding, and in order to save space, this section describes the hollow building panel while describing the unit component of the hollow building panel.

[0043] Please refer to Figures 1 to 3 , Figure 1 This is a longitudinal cross-sectional structural diagram of the modular structure provided by the present invention, which shows the arrangement and connection structure of the vertical wall panel 100 and the horizontal wall panel 200; Figure 2 for Figure 1 Enlarged view of part B; Figure 3 for Figure 1 A cross-sectional structural diagram of a Z-shaped connector 400. This modular structure may include vertical wall panels 100 and flat wall panels 200. Vertical wall panels 100 are vertically arranged panels and may include multiple vertical wall panels. Multiple vertical wall panels 100 can be arranged to form a suitable space and achieve indoor-outdoor separation. Flat wall panels 200 include top flat wall panels, which serve as the structure's roof, and bottom flat wall panels, which serve as the structure's floor.

[0044] like Figure 1 As shown, the upper and lower ends of the vertical wall panel 100 are respectively fixed to a flat wall panel 200. In this embodiment, the side walls of the flat wall panel 200 are opposite to the inner wall surfaces of the vertical wall panel 100, that is, the side walls of the top flat wall panel 200 are opposite to the inner wall surface above the vertical wall panel 100, and the side walls of the bottom flat wall panel 200 are opposite to the inner wall surface below the vertical wall panel 100.

[0045] In addition, a Z-shaped connector 400 is also included; the Z-shaped connector 400 includes a flat connecting plate 410, a vertical connecting plate 420, a supporting plate 430 and a limiting plate 440 connected in sequence, and a limiting groove 401 is formed between the vertical connecting plate 420, the supporting plate 430 and the limiting plate 440.

[0046] During assembly, the end of the vertical wall panel 100 is inserted into the limiting groove 401, the vertical connecting plate 420 is located between the side wall surface of the flat wall panel 200 and the inner wall surface of the vertical wall panel 100, and the flat connecting plate 410 is fitted and positioned with the upper surface or lower surface of the flat wall panel 200, thereby keeping the end of the vertical wall panel 100 and the flat wall panel 200 fixed.

[0047] Figure 2 The diagram illustrates the connection structure between the sidewalls of the flat wall panel 200 and the lower portion of the vertical wall panel 100. As can be seen from the figure, in this case, the lower end of the vertical wall panel 100 is inserted into the retaining groove 401, and the flat connecting plate 410 of the Z-shaped connector 400 is supported on the upper surface of the bottom flat wall panel 200. This ensures accurate positioning between the flat wall panel 200 and the vertical wall panel 100, while also ensuring a reliable connection between the two.

[0048] At the same time, referring to Figure 1, when the side wall surface of the flat wall panel 200 is connected to the upper portion of the vertical wall panel 100, the upper end of the vertical wall panel 100 is inserted into the limiting groove 401, and the flat connecting plate 410 of the Z-shaped connector 400 is supported on the lower surface of the top flat wall panel 200. The limiting groove 401 also covers the upper end of the vertical wall panel 100. On the one hand, it can realize the positioning of the vertical wall panel 100, and at the same time, it can realize the accurate positioning between the flat wall panel 200 and the vertical wall panel 100, ensuring the reliability of the connection between the two. In short, the limiting groove 401 of the Z-shaped connector 400 can realize the positioning between the vertical wall panel 100 and the flat wall panel 200. At the same time, by utilizing the vertical wall panel 100 and the Z-shaped connector 400, combined with the large area of ​​the flat wall panel 200, it can ensure the relative positioning of the vertical wall panel 100 and the flat wall panel 200, and ensure the reliability of the relative fixation between the two.

[0049] Refer again Figure 3 The outer edge of the limiting plate 440 is inclined in a direction away from the vertical connecting plate 420. This makes it easier for the end of the vertical wall panel 100 to be inserted into the limiting groove 401, achieving rapid positioning and thus improving assembly efficiency.

[0050] It is understood that the flat connecting plate 410 is fixed to the upper surface or lower surface of the flat wall panel 200 by fasteners; the limiting plate 440 can also be fixed to the surface of the vertical wall panel 100 by fasteners, thereby improving the reliability of the fixation between the vertical wall panel 100 and the flat wall panel 200.

[0051] like Figure 2 As shown, the modular structure further includes an L-shaped connector 500 formed by two connecting side panels; one connecting side panel of the L-shaped connector 500 is attached to and fixed to the flat connecting plate 410, and the other connecting side panel is attached to and fixed to the surface of the vertical wall panel 100, thereby keeping the vertical wall panel 100 and the flat wall panel 200 fixed, thereby enhancing the reliability of the fixation between the two.

[0052] Please refer to Figure 4 , Figure 4 Shown Figure 1 This partial cross-sectional view of the modular structure provided by the present invention illustrates the connection structure of two vertical wall panels 100. As shown, the two vertical wall panels 100 are perpendicular to each other and connected by two L-shaped connectors 500a and 500b. L-shaped connector 500a is smaller and located on the inside, with its two connecting side panels respectively attached to and fixed to the inner surfaces of the two vertical wall panels 100. L-shaped connector 500b is larger and located on the outside, with its two connecting side panels respectively attached to and fixed to the outer surfaces of the two vertical wall panels 100.

[0053] The vertical wall panels 100 and the horizontal wall panels 200 may be existing hollow building panels, or may be partially hollow building panels.

[0054] The following describes the structure of the unit components of the hollow building panel provided by the present invention. Figure 5 , Figure 5 This utility model provides a cross-sectional view of a unit component of a hollow building panel. The unit component is a long, strip-shaped object formed by bending a sheet of predetermined length and width in an appropriate manner. In this embodiment, the sheet is 2mm thick galvanized steel. The unit component is unique in its cross-sectional structure, comprising a first panel portion 10, a second panel portion 20, and a core panel 30.

[0055] The two ends of the core plate 30 are connected to the inner ends of the first panel portion 10 and the second panel portion 20 via a first connecting hem portion 40 and a second connecting hem portion 50. The connecting hem portion is formed by composite sheet materials, and the first connecting hem portion 40 and the second connecting hem portion 50 respectively include a first bent composite section 41 and a second bent composite section 51 inclined outward.

[0056] The outer ends of the first panel portion 10 and the second panel portion 20 are respectively formed with a first sewing cuff 11 and a second sewing cuff 21 bent inward and inward to form a hook shape.

[0057] The first bent composite section 41 and the second bent composite section 51 correspond to the first sewing flange 11 and the second sewing flange 21 respectively, so that the unit components overlap with each other, thereby facilitating the sewing and fixing of the unit components.

[0058] Please refer to Figure 6 and Figure 7 , Figure 6 For two adjacent Figure 5 The corresponding diagram of the unit components shown is Figure 7 The figure illustrates the interlaced state of the bent composite sections and seamed flanges of two adjacent unit components. It can be determined that the above-mentioned unit components, formed integrally by bending, can be sequentially arranged in the cross-sectional direction, with the first bent composite section 41 of the first unit component inserted between the first seamed flange 11 of the second unit component and the first panel portion 10; and the second bent composite section 51 of the first unit component inserted between the second seamed flange 21 of the second unit component and the second panel portion 20.

[0059] Refer again Figure 8 and Figure 9 , Figure 8 It shows the structure of the two adjacent unit components with bent composite sections and sewn flanges. Figure 9 for Figure 8Enlarged structural diagram of section A. The first bent composite section 41 of the first unit component is secured to the first stitched flange 11 and first panel portion 10 of the second unit component. The second bent composite section 51 of the first unit component is secured to the second stitched flange 21 and second panel portion 20 of the second unit component. This allows adjacent unit components to be stitched and secured. Several unit components are sequentially connected and secured in the same manner to form a hollow building panel of appropriate size. The first bent composite section 41 of the first unit component cooperates with the first stitched flange 11 of the second unit component to conveniently form a hollow building panel. Furthermore, the unit components are secured to each other by stitching together the first bent composite section 41 of the first unit component and the first stitched flange 11 of the second unit component, and then connected to the first panel portion 10 and the second panel portion 20 in conjunction with the core panel 30. This improves the production efficiency of the hollow building panel while maintaining its mechanical properties.

[0060] In this embodiment, when bending to form unit components, the first and second panel portions 10, 20 can be extended in parallel directions. Before sewing adjacent unit components, the first and second panel portions 10, 20 can be expanded outward using a suitable device to form a tapered structure, thereby facilitating the staggering of adjacent unit components. This ensures that the first and second panel portions 10, 20 and the core plate 30 are aligned relative to each other before and after the hollow building panel is sewn together. This reduces stress and deformation in the hollow building panel after sewing, thereby improving the stability of the hollow building panel's mechanical performance. Of course, when bending to form unit components, the first and second panel portions 10, 20 can also be extended in a tilted manner. This allows the tapered structure formed by the first and second panel portions 10, 20 to facilitate the joining of the unit components during sewing, thereby facilitating sewing and securing. This can improve the production efficiency of the hollow building panel and reduce the cost of the hollow building panel.

[0061] In this embodiment, the core panel 30 extends perpendicularly to the first panel portion 10. This fully utilizes the core panel 30's supporting function, ensuring the rigidity and stability of the hollow building panel in the thickness direction. Depending on practical needs, the core panel 30 can also be arranged with its extension direction tilted relative to the extension direction of the first panel portion 10 to achieve higher strength or rigidity in specific directions.

[0062] Please refer to Figures 5 to 9In this embodiment, the first connecting hem portion 40 and the second connecting hem portion 50 further include a first fold-accommodating recessed portion 42 and a second fold-accommodating recessed portion 52, respectively. The first fold-accommodating recessed portion 42 is connected between the first bending composite section 41 and the first panel portion 10, and the second fold-accommodating recessed portion 52 is connected between the second bending composite section 51 and the second panel portion 20. The first fold-accommodating recessed portion 42 and the second fold-accommodating recessed portion 52 respectively form a first fold-accommodating groove and a second fold-accommodating groove to accommodate the stitched hem. Preferably, the depth of each of the first and second fold-accommodating grooves is no less than four times the thickness of the sheet material forming the unit component. This allows the stitched hem to be located within the side surfaces of the first and second panel portions 10, 20, thereby ensuring a smooth surface of the hollow building panel and improving the performance of the hollow building panel.

[0063] As described above, the above-mentioned unit components are arranged in sequence and sewed together to form the hollow building panel provided by the present invention. Please refer to Figure 10 and Figure 11 , Figure 10 Provide an overall screenshot of the hollow building panel for this utility model, Figure 11This is a side view of a hollow building panel provided by the present invention. In this hollow building panel, the first bent composite section 41 of the first unit component is inserted between the first stitched flange 11 of the second unit component and the first panel portion 10; the second bent composite section 51 of the first unit component is inserted between the second stitched flange 21 of the second unit component and the second panel portion 20. Furthermore, the first bent composite section 41 of the first unit component maintains affixed fit with the first stitched flange 11 and the first panel portion 10 of the second unit component, while the second bent composite section 51 of the first unit component maintains affixed fit with the second stitched flange 21 and the second panel portion 20 of the second unit component. Using these unit components to form a hollow building panel can produce corresponding technical effects. As described above, in the hollow building panel, the first connecting hem portion 40 and the second connecting hem portion 50 can further include a first fold-accommodating recessed portion 42 and a second fold-accommodating recessed portion 52, respectively. The first fold-accommodating recessed portion 42 connects the first bent composite section 41 and the first panel portion 10, and the second fold-accommodating recessed portion 52 connects the second bent composite section 51 and the second panel portion 20. The first fold-accommodating recessed portion 42 and the second fold-accommodating recessed portion 52 respectively form a first fold-accommodating groove and a second fold-accommodating groove to accommodate the stitched hem. This can also improve the surface flatness of the hollow building panel. At the same time, the first stitched flange 11 of the first unit component can be inserted between the first bent composite section 41 and the first folded accommodating recess 42 of the second unit component; the second stitched flange 21 of the first unit component can be inserted between the second bent composite section 51 and the second folded accommodating recess 52 of the second unit component; and the first stitched flange 11 of the first unit component is kept in close contact with the first bent composite section 41 and the first folded accommodating recess 42 of the second unit component; and the second stitched flange 21 of the first unit component is kept in close contact with the second bent composite section 51 and the second folded accommodating recess 52 of the second unit component. This can improve the reliability of the stitched connection between the unit components and enhance the rigidity of the hollow building panel.

[0064] Please refer to Figure 12 , Figure 12The utility model provides a cross-sectional structural diagram of a hollow building panel, illustrating the edge blocking structure of the hollow building panel; the figure uses dotted lines to illustrate unit components, and solid lines to illustrate edge unit components and blocking components. The hollow building panel also includes an edge unit component and a blocking component 60; the edge unit component is formed by bending a complete plate material, and includes a first edge panel portion 1a, a second edge panel portion 2a, and an edge core plate 3a; the two ends of the edge core plate 3a are connected to the inner ends of the first edge panel portion 1a and the second edge panel portion 2a via a first edge connecting folding portion 40a and a second edge connecting folding portion 50a, respectively; the first edge bending compound section 41a of the edge unit component is inserted between the first stitched flange 11 of the outermost unit component and the first panel portion 10; the second edge bending compound section 51a of the edge unit component is inserted between the second stitched flange 21 of the outermost unit component and the second panel portion 20; and the first edge bending compound section 41a of the edge unit component is kept in contact with the first stitched flange 11 and the first panel portion 10 of the outermost unit component, and the second edge bending compound section 51a of the edge unit component is kept in contact with the second stitched flange 21 and the second panel portion 20 of the outermost unit component;

[0065] The two sides of the sealing member 60 are connected to the first edge panel portion 1a and the second edge panel portion 2a, respectively, to seal the outer edge opening of the edge unit member. The edge unit member and the sealing member 60 can seal the opening of the hollow building panel, not only ensuring the strength and rigidity of the hollow building panel, but also improving the safety of the hollow building panel.

[0066] In this embodiment, except for the lack of first and second seamed flanges 11 and 21, the edge unit components can have the same structure and shape as other unit components to facilitate sealing the edges of the hollow building panel openings. Alternatively, a folded, recessed portion can be formed, which will not be described in detail here.

[0067] In this embodiment, the first edge panel portion 1a and the second edge panel portion 2a can extend parallel to each other, and their outer ends can be flush with the outer surface of the blocking member 60 to ensure the smoothness of the overall profile of the hollow building panel. The blocking member 60 can have right-angled flanges 61 formed on either side, which adhere to and secure the inner surfaces of the first edge panel portion 1a and the second edge panel portion 2a, respectively. This improves the strength and rigidity of the hollow building panel.

[0068] Refer again Figure 5In one embodiment of the present invention, the first panel portion 10 and the second panel portion 20 are symmetrically arranged. This ensures the flatness of the hollow building panel and prevents deflection. Furthermore, the cross-sectional width W1 of the first panel portion 10 is 1.3 to 1.9 times the cross-sectional width W2 of the core panel 30. This ensures the support provided by the panel portion of the core panel 30, thereby ensuring the strength of the hollow building panel. Furthermore, the cross-sectional width W3 of the first and second seamed flanges 11 and 21 is greater than one-tenth of the cross-sectional width W1 of the first panel portion 10, ensuring appropriate connection dimensions between the unit components and, therefore, ensuring reliable connections between the unit components in the hollow building panel.

[0069] Although preferred embodiments of the present invention have been described above, those skilled in the art will appreciate that many changes or modifications may be made to the details of design, construction or operation without departing from the scope of the present invention.
