Description

Technical Field

[0001] The invention relates to the technical field of curtain wall structures, and in particular to a unitized partition wall system free of accessory assembly. Background Art

[0002] The traditional unitized partition wall unit is composed of vertical keels, horizontal keel frame structure and panel materials.

[0003] In the prior art, the horizontal and vertical purlins are often assembled by welding or by connecting them with metal accessories such as angle brackets. However, the welding method requires professional welders to operate, which has high labor costs and is extremely inconvenient to process the welds later. In addition, most frame structures are relatively high, which poses certain safety hazards and is also very unstable for working at heights. The accessory connection method requires a large amount of on-site work, and accessories such as angle brackets must be installed first, and then the angle brackets and horizontal purlins must be installed. The overall installation efficiency is not high, and once the angle brackets are loose, it is easy to damage the entire frame structure, resulting in poor stability.

[0004] Therefore, a unitized partition wall system without accessory assembly is proposed to solve the above-mentioned problems. Summary of the invention

[0005] Technical issues solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a unitized partition wall system that does not require assembly of accessories, which can effectively solve the problems of inconvenient installation and poor stability of the partition wall frame structure in the prior art.

[0010] Furthermore, the side end surface of the transverse keel is inserted into the concave portion of the first vertical keel or the concave surface of one side of the second vertical keel.

[0011] Furthermore, unit assembly grooves are provided on the concave portion of the first vertical keel and the two convex side edges of the concave surface of one side of the second vertical keel, and the upper and lower four side walls of the transverse keel are plugged into and matched with the unit assembly grooves.

[0012] Furthermore, the concave portion of the first vertical keel, the front ends of two side edges protruding from the concave surface of one side of the second vertical keel, and the front end of the transverse keel are all provided with connecting holes.

[0013] Furthermore, a concave surface on one side of the second vertical keel can be plugged into and matched with a convex portion of the first vertical keel.

[0014] Furthermore, the concave portion of the first vertical keel, the protruding side edges of the concave surfaces on both sides of the second vertical keel, and the upper and lower four side walls of the transverse keel all adopt a stacked wall design.

[0015] Furthermore, at least one side wall on the transverse keel is bent into a mounting portion, and the mounting portion adopts a stacked wall design.

[0016] The present invention also proposes a unitized partition wall system that does not require accessory assembly, including one of the above-mentioned unitized partition wall keel frames, including a wall body and a decorative panel arranged parallel to the front end of the wall body, and the rear side of the decorative panel cooperates with the mounting portion at the front end of the horizontal keel through a hook.

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] The present invention can quickly complete the installation by directly overlapping the horizontal and vertical keels, and finally only needs to be fastened with screws. It has the characteristics of simple installation and low cost. In addition, when the entire keel structure is assembled in the factory or on-site, the horizontal and vertical keels can be quickly fixed, and no additional accessories such as angle codes are required to complete the assembly.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] The present invention will be further described below in conjunction with the embodiments.

[0050] Embodiment 1:

[0051] See attached Figure 1-19 This case proposes a unitized partition wall system that can be assembled without accessories, including at least two vertical purlins 1 and a horizontal purlin 2 placed horizontally between two adjacent vertical purlins 1. In actual assembly, the number of vertical purlins 1 is set according to the length of the actual assembled wall surface. The vertical purlins 1 include a first vertical purlin 11 and a second vertical purlin 12. The two opposite end surfaces of the first vertical purlin 11 are a convex portion 111 and a concave portion 112, respectively. The cross-section of the second vertical purlin 12 is I-shaped, and the concave surfaces on both sides thereof are plugged into and matched with the concave portion 112 of the first vertical purlin 11.

[0052] In some usage scenarios, such as Fig.10 As shown in the figure, the assembly length of the transverse keel 2 is relatively short, and a first vertical keel 11 and a second vertical keel 12 are usually provided, and a plurality of transverse keels 2 are horizontally placed between the first vertical keel 11 and the second vertical keel 12, and the overall frame structure is in a well shape.

[0053] If the transverse keel 2 is assembled longer, Fig.11 as shown in .

[0054] It should be noted that the end surface of the vertical keel 1 facing the horizontal keel 2 is plugged and locked with the vertical keel 1;

[0055] And as attached Fig.13 When the transverse keel 2 shown in the figure is shorter, it can be used as the side structure of the partition wall system to distinguish it from the main body, so that the layout distribution of the entire wall is reasonable and beautiful.

[0056] And attached Fig.14 The structure shown in is the structure state in which the structures in the above are combined together.

[0057] The concave portion 112 of the first vertical keel 11 can be fixed to two side surfaces of the transverse keel 2 , and both sides of the second vertical keel 12 can be fixed to two side surfaces of the transverse keel 2 .

[0058] In this embodiment, the cross-section of the transverse keel 2 is I-shaped, including two parallel transverse sides and a vertical side perpendicular to the two transverse sides, and there is a certain distance between the two vertical sides, so that there is a cavity in the middle of the transverse keel 2, forming a rectangular and stable force-bearing structure.

[0059] The first vertical purlin 11 and the second vertical purlin 12 also have a rectangular cavity in the middle, and the edges of the vertical purlins are rounded, so the bearing capacity is better than that of ordinary steel structures.

[0060] The side end surface of the transverse keel 2 is inserted into the concave portion 112 of the first vertical keel 11 or the concave surfaces on both sides of the second vertical keel 12 .

[0061] Therefore, during actual on-site assembly, there is no need to use angle brackets or screws to fix the horizontal and vertical keels. In addition, since the number of horizontal keels between adjacent vertical keels is not one, and the horizontal and vertical keels in the prior art are mostly fixed at the top and bottom with angle brackets, if the angle brackets are bent or damaged due to staff mistakes or long-term use, the horizontal and vertical keel structure is easily deformed or collapsed. In this embodiment, there is no need to use a large number of angle brackets, and only plug-in fixation is adopted. Not only is the structure stable, but even if the plug-in structures on both sides of one of the horizontal keels 2 fail (break or fall off), the other horizontal keels 2 can still maintain the integrity of the entire steel structure.

[0062] Specifically, unit assembly grooves 101 are provided on the concave portion 112 of the first vertical keel 11 and the two side edges 10 protruding from the concave surface on one side of the second vertical keel 12. Since the transverse keel 2 has four upper and lower side walls 20 on both sides, during assembly, the side walls 20 on both sides of the transverse keel 2 will be inserted into the corresponding unit assembly grooves 101.

[0063] In order to further improve the fixing effect, the concave portion 112 of the first vertical keel 11 and

[0064] The front ends of the two side edges 10 protruding from the concave surface of one side of the second vertical keel 12 and the front end of the transverse keel 2 are provided with connection holes. After the first vertical keel 11 or the second vertical keel 12 is connected to the transverse keel 2, the fixing effect can be further improved by screwing in screws. In the actual assembly site, the same steel structure wall structure only needs to screw in a few screws to complete the assembly of the entire steel structure, which greatly improves the on-site assembly efficiency.

[0065] In some usage scenarios where the length of the steel structure needs to be extended, the concave surface on one side of the second vertical keel 12 can be plugged into the convex portion 111 of the first vertical keel 11 to form an integral vertical keel, but both sides of the vertical keel have a concave surface, so that the transverse keel 2 can be fixed on both sides.

[0066] It is worth noting that in the present embodiment, since the concave portion 112 of the first vertical keel 11, the protruding side edges 10 on both sides of the concave surface of the second vertical keel 12, and the upper and lower four side walls 20 of the transverse keel 2 all serve as fixed points, that is, they bear the weight of the entire transverse keel 2, in order to improve the load-bearing capacity and avoid bending caused by long-term use, a stacked wall design is adopted in these parts.

[0067] Specifically, the profile material of the horizontal and vertical keels is 1.0mm thick steel profile, and the load-bearing and torsion-resistant positions are both designed with stacked walls. The actual effective thickness is at least 2.0mm. From the cross-sectional view, the horizontal and vertical keels are both formed by bending a steel profile, which not only ensures the mechanical properties, but also effectively reduces material costs.

[0068] In this embodiment, a portion of the side wall 20 at the bottom side of the front end of the transverse keel 2 extends forward and bends upward at the end to form a mounting portion 21. The mounting portion 21 is used to mount other partition wall components and thus also serves as a load-bearing point, where a stacked wall design is also adopted.

[0069] Embodiment 2:

[0070] This embodiment is based on embodiment 1, as shown in the attached Fig.17 As shown, the transverse keel 2 in this embodiment is arranged between two decorative panels 4, and what is different from the aforementioned embodiment is that the side walls 20 on both sides of the upper end of the transverse keel 2 extend outward to form a mounting portion 21, so that when the transverse keel 2 and the vertical keel are fixed by screws, the two upper mounting portions 21 can be snapped into the hooks 41 on the adjacent decorative panels 4, thereby being able to fix the two parallel decorative panels 4, and providing more abundant assembly solutions according to the actual assembly requirements.

[0071] Embodiment 3:

[0072] The present invention also proposes a unitized partition wall system that can be assembled without accessories, including one of the above-mentioned unitized partition wall keel frames, including a wall body 3 and a decorative panel 4 arranged parallel to the front end of the wall body 3, and a hook 41 is fixed to the rear side of the decorative panel 4 by screws. During actual assembly, the unitized partition wall keel frame is assembled first, and then the hook 41 is fixed to the decorative panel 4, and finally the entire decorative panel 4 is hung on the unitized partition wall keel frame, that is, the hook 41 is matched with the mounting portion 21 on the transverse keel 2.

[0073] It is worth mentioning that the bottom of the hook 41 is inclined toward one side of the decorative panel 4, and the bottom end is rounded. The hook 41 can be made of hard plastic or metal, so it has a certain toughness and can better "clamp" the mounting part 21 when assembled with the mounting part 21.

[0074] Usually, during the use of the partition wall, there will be some needs to mount other household items, and holes will usually be opened directly on the end face of the decorative panel. This not only affects the appearance, but may even cause partial tearing of the decorative panel 4. In the present embodiment, since there is a certain distance between the keel and the decorative panel, a connecting portion 13 with a concave cross-section can be fixed to the front end of the second vertical keel 12 by screws, and the connecting portion 13 has a connecting hole. There is a gap 42 between adjacent decorative panels 4 to expose the connecting hole on the connecting portion 13, so that some commonly used hanging rods and other load-bearing tools can be fixed on the exposed connecting hole, without the need to open a hole on the decorative panel 4.

[0075] It should be noted that the wall connecting member 5 is also included, and the first vertical purlin 11 and / or the second vertical purlin 12 are fixed to the wall 3 through the wall connecting member 5, and the wall connecting member 5 is fixed to the wall surface and the vertical purlins through screws.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
