Description

Technical Field

[0001] The utility model relates to a 3D printed building wall, and belongs to the technical field of building construction. Background Art

[0002] With the increasing development of 3D printing technology, 3D printing technology can now be applied to the construction of buildings. 3D printing can directly print the load-bearing walls or partition walls of buildings. Its fast and convenient advantages can improve the construction efficiency of building construction.

[0003] Most of the walls printed using 3D printing do not have any reinforcement structure added inside, so the structural strength of the wall is relatively low. If steel cages or other steel structures are added to the wall, the gaps inside the wall will need to be filled with concrete slurry later, which will increase the production efficiency and cycle of the wall, which is contrary to the manufacturing concept of 3D printed walls. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a 3D printed building wall, which solves the problem that the structural strength of the 3D printed wall in the prior art is low. If a steel cage or other steel structure is added to the wall, the gap inside the wall needs to be filled with concrete slurry at a later stage, which will increase the production efficiency and cycle of the wall.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a building 3D printed wall, including a printing layer, which is arranged in a closed loop and extends horizontally in a straight line. The printing layer is vertically stacked with several layers, and the printing layer closed loop forms a support plate space and a support column space. Several support column spaces are arranged along the extension direction of the printing layer, and the support plate space is arranged between adjacent support column spaces and connected with the support column space. A support column is arranged in the support column space, and the extension direction of the support column is the same as the stacking direction of the several printing layers. A support plate is arranged in the support plate space, and both ends of the support plate extend into the support column space and are connected with the support column.

[0006] By adopting the above technical solution, formed support columns and support plates are directly added in the support column space and the support plate space, and the support columns and support plates fill the space of the support plate space and the support column space, so that the support columns and support plates directly provide support for the printing layer, reducing the steps of concrete pouring and filling, which is beneficial to improving the production efficiency of the printed wall and conforms to the fast and convenient manufacturing concept of 3D printed walls.

[0007] The utility model is further configured as follows: an outer side surface of the support column is provided with a plug-in slot in the same extension direction as the support column, an opening is provided on one side of the plug-in slot facing the support plate space, and the end of the support plate extends into the plug-in slot and is clamped with the support column.

[0008] By adopting the above technical solution, the support columns and the support plates are connected to each other. When the support plates or support columns are subjected to force, the force can be transmitted to the surrounding support columns or support plates, so that the wall can be subjected to force as a whole, thereby greatly improving the structural strength of the printed wall.

[0009] The utility model is further configured as follows: a matching groove is opened on the end face of the support column in the extension direction, a matching rod with the same opening profile of the matching groove is fixedly arranged at one end of the support column away from the matching groove, a plurality of vertically stacked support columns are arranged in the same support column space, and the matching rods of adjacent support columns extend into the matching groove for matching connection.

[0010] By adopting the above technical solution, when the vertical height of the printed wall is high and greater than the length of a single support column, the assembly and connection of adjacent support columns is completed by inserting one end of the matching rod of the new support column into the matching groove. At this time, the two support columns can form a whole and conduct force, thereby greatly improving the size selection range of the printed wall.

[0011] The utility model is further configured as follows: reserved internally threaded tubes located on both sides of a support plate are fixedly arranged at the stacking surfaces of a plurality of printed layers, the reserved internally threaded tubes extend toward the support plate, a plurality of through holes which can be fully aligned with the openings of the plurality of reserved internally threaded tubes are provided on the support plate, a limiting space is formed after the plurality of reserved internally threaded tubes are fully aligned with the through holes, a connecting rod is provided in the limiting space, the connecting rod is threadedly connected to the inner wall of the reserved internally threaded tube, an end of the connecting rod away from the support plate extends to the outer side of the reserved internally threaded tube away from the support plate and an internally threaded hole is provided on the end face.

[0012] By adopting the above technical solution, after several printed layers are stacked, the reserved internal threaded tube between adjacent printed layers is fixedly connected to the printed layers. At this time, the reserved internal threaded tube and the support plate are passed through the connecting rod. At this time, the support plate can be fixedly connected to the reserved internal threaded tube through the connecting rod, and the connecting rod limits the movement of the support plate after installation, which can improve the stability of the support plate. Moreover, since the reserved internal threaded tube is fixed to the printed layer, even if there is a gap between the support plate and the inner wall of the printed layer, the external force exerted on the printed layer can be further stably transmitted to the support plate, which is beneficial to the force conduction effect in the stressed state and is beneficial to further improving the structural strength of the printed wall.

[0013] The utility model is further configured as follows: a main decorative panel is arranged on the outer side surface of the printed layer, the extension direction of the main decorative panel is the same as the stacking direction of the printed layer, a plurality of mounting countersunk holes are opened on the main decorative panel, the mounting countersunk holes are aligned with the internal threaded holes on the end surface of the connecting rod, the main decorative panel is abutted against the reserved internal threaded tube and the end of the connecting rod extends into the mounting countersunk hole, a threaded rod is arranged in the mounting countersunk hole, the threaded rod extends into the internal threaded hole and is threadedly connected with the internal threaded hole.

[0014] By adopting the above technical solution, when the main decorative panel needs to be installed on the outside of the printed layer, through the connection between the threaded rod and the connecting rod, the gravity of the main decorative panel can be transmitted to the connecting rod through the threaded rod, and then transmitted to the support plate, which can avoid the printed layer from directly participating in the load-bearing. While ensuring the stability of the load-bearing, it can avoid the printed layer participating in the load-bearing and causing surface damage to affect the structural strength of the printed wall.

[0015] The utility model is further configured that: the space inside the printing layer except the space of the support plate and the space of the support column is filled with concrete slurry.

[0016] By adopting the above technical solution, according to the use scenario of the printed wall, when the printed wall requires higher structural strength, by filling the gaps with concrete slurry, the inside of the printed layer is made completely solid. Compared with the hollow printed layer, the upper limit of the load it can bear is higher, which is conducive to further improving the structural strength of the printed wall.

[0017] The beneficial effect of the utility model is that by directly adding formed support columns and support plates in the support column space and the support plate space, and the support columns and support plates fill the space of the support plate space and the support column space, the support columns and support plates directly provide support for the printing layer, reducing the steps of concrete pouring and filling, which is beneficial to improving the production efficiency of the printed wall and conforms to the concept of fast and convenient manufacturing of 3D printed walls.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the following is a brief introduction Figure 1-5 Shown, the utility model is further described.

[0025] like Figure 1-2 As shown, a 3D printed wall for building includes a printing layer 10, which is arranged in a closed loop and extends horizontally and linearly. The printing layer 10 is stacked vertically and has several layers. The printing layer 10 is closed to form a support plate space 11 and a support column space 12. Several support column spaces 12 are arranged along the extension direction of the printing layer 10. The support plate space 11 is arranged between adjacent support column spaces 12 and communicates with the support column space 12. A support column 20 is arranged in the support column space 12. The extension direction of the support column 20 is the same as the stacking direction of the several printing layers 10. A support plate 23 is arranged in the support plate space 11. Both ends of the support plate 23 extend into the support column space 12 and are connected to the support column 20. The inner support plate space 11 and the support column space 12 of the printing layer 10, as well as the space and gap outside the support plate space 11 and the support column space 12 are filled with concrete slurry.

[0026] like Figure 2-3 As shown, the outer side surface of the support column 20 is provided with a plug-in slot 25 in the same direction as the extension direction of the support column 20, and the plug-in slot 25 is provided with an opening on the side facing the support plate space 11, and the end of the support plate 23 extends into the plug-in slot 25 and is engaged with the support column 20. A matching slot 21 is provided on the end surface in the extension direction of the support column 20, and a matching rod with the same opening profile as the matching slot 21 is fixedly provided at one end of the support column 20 away from the matching slot 21. A plurality of vertically stacked support columns 20 are provided in the same support column space 12, and the matching rods of adjacent support columns 20 extend into the matching slot 21 for matching connection.

[0027] like Figure 2-3As shown, reserved internal threaded tubes 13 located on both sides of the support plate 23 are fixedly arranged at the stacking surfaces of several printed layers 10, and the reserved internal threaded tubes 13 extend toward the support plate 23. The support plate 23 is provided with a plurality of through holes that can be completely aligned with the openings of the reserved internal threaded tubes 13. After the reserved internal threaded tubes 13 are completely aligned with the through holes, a limiting space is formed, and a connecting rod 24 is arranged in the limiting space. The connecting rod 24 is threadedly connected to the inner wall of the reserved internal threaded tube 13, and one end of the connecting rod 24 away from the support plate 23 extends to the outer side of the reserved internal threaded tube 13 away from the support plate 23 and an internal threaded hole is provided on the end face. A main decorative panel 30 is provided on the outer side surface of the printed layer 10, and the extension direction of the main decorative panel 30 is the same as the stacking direction of the printed layer 10. A plurality of mounting countersunk holes 31 are provided on the main decorative panel 30, and the mounting countersunk holes 31 are aligned with the internal threaded holes on the end surface of the connecting rod 24. The main decorative panel 30 is abutted against the reserved internal threaded tube 13, and the end of the connecting rod 24 extends into the mounting countersunk hole 31. A threaded rod is provided in the mounting countersunk hole 31, and the threaded rod extends into the internal threaded hole and is threadedly connected to the internal threaded hole.

[0028] like Figure 5 As shown, after the printed wall is installed, auxiliary decorative panels 32 can be installed on both ends of the printed wall. The auxiliary decorative panels 32 can fill the space between the printed layer 10 and the main decorative panel 30, which is beneficial to improve the overall aesthetics of the wall. The upper end height of the main decorative panel 30 after installation can be higher than the stacking height of several printed layers 10, and cooperate with the auxiliary decorative panel 32 to form an upward-opening expansion groove 33. At this time, the bracket of the ceiling or decorative light panel can be installed in the expansion groove 33, so that the ceiling or decorative light panel can be installed above the printed wall, thereby improving the expandability of the printed wall.

[0029] By directly adding formed support columns 20 and support plates 23 in the support column space 12 and the support plate space 11, and the support columns 20 and support plates 23 fill the space of the support plate space 11 and the support column space 12, so that the support columns 20 and support plates 23 directly provide support for the print layer 10, the steps of concrete pouring and filling are reduced, which is conducive to improving the production efficiency of the printed wall and conforms to the fast and convenient manufacturing concept of 3D printed walls. By making the support columns 20 and the support plates 23 mutually clamped, when the support plates 23 or the support columns 20 are subjected to force, the force can be transmitted to the surrounding support columns 20 or support plates 23, so that the wall can be subjected to force as a whole, which greatly improves the structural strength of the printed wall.

[0030] When the vertical height of the printed wall is high and greater than the length of a single support column 20, the assembly connection of the adjacent support columns 20 is completed by inserting one end of the matching rod set in the new support column 20 into the matching groove 21. At this time, the two support columns 20 can form a whole and conduct force, thereby greatly improving the size selection range of the printed wall. After several printed layers 10 are stacked, the reserved internal threaded tube 13 between the adjacent printed layers 10 is fixedly connected to the printed layer 10. At this time, the reserved internal threaded tube 13 and the support plate 23 are passed through the connecting rod 24. At this time, the support plate 23 can be fixedly connected to the reserved internal threaded tube 13 by the connecting rod 24, and the connecting rod 24 limits the movement of the support plate 23 after installation, which can improve the stability of the support plate 23. Moreover, since the reserved internal threaded tube 13 is fixed to the printed layer 10, even if there is a gap between the support plate 23 and the inner wall of the printed layer 10, the external force received by the printed layer 10 can be further stably transmitted to the support plate 23, which is beneficial to the force conduction effect of the stress state and is beneficial to further improve the structural strength of the printed wall. When the main decorative panel 30 needs to be installed on the outside of the printed layer 10, through the connection between the threaded rod and the connecting rod 24, the gravity of the main decorative panel 30 can be transmitted to the connecting rod 24 through the threaded rod, and then transmitted to the support plate 23, which can avoid the printed layer 10 from directly participating in the load-bearing, and can ensure the stability of the load-bearing while avoiding the printed layer 10 participating in the load-bearing and causing surface damage that affects the structural strength of the printed wall.

[0031] According to the usage scenario of the printed wall, when the printed wall requires higher structural strength, by filling the gaps with concrete slurry, steel bars can be inserted into the larger gaps when necessary to improve the bending resistance of the printed wall, so that the interior of the printed layer 10 is completely solid. Compared with the hollow printed layer 10, the upper limit of the load it can bear is higher, which is conducive to further improving the structural strength of the printed wall.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
