Description

Technical Field

[0001] The present invention relates to the field of building technology, and particularly to a keel. Background Art

[0002] With the development of modern architecture and the application of new building materials, the non-load-bearing partition walls of housing buildings have gradually evolved from traditional solid clay bricks to various lightweight boards or blocks. The lightweight partition wall composed of light steel keel and gypsum board is a non-load-bearing partition wall system with a light steel keel as the framework and a paper-faced gypsum board as the surface layer, with a hollow interior (or sound insulation and thermal insulation layers arranged), and two flat sides. It has many advantages such as light self-weight, non-flammability, sound insulation, thermal insulation, good seismic performance, simple construction, and short construction period. It is suitable for industrial and civil buildings, especially for non-load-bearing partition walls during new construction, expansion, or renovation of high-rise buildings. The internal partition walls used in decoration projects are widely applied in residential buildings, hotels, airports, railway stations, shopping malls, theaters, restaurants, factories and other venues.

[0003] Currently, the framework of lightweight partition walls generally consists of ceiling and floor horizontal keels, vertical wall keels (i.e., partition wall keels), and cross braces assembled together; due to the main load-bearing role of the vertical wall keels in the partition wall, the width of the vertical wall keels determines the thickness of the lightweight partition wall.

[0004] However, for the only width sequence of 50mm, 75mm, 100mm, and 150mm for the vertical wall keels, the selection of wall thickness is restricted. For thicker walls or walls that must use intermediate sizes, multiple keels need to be stacked for construction layout, otherwise it can only be achieved by adjusting the surface panels. This not only increases the number of partition wall keels used, but also makes the construction process of the lightweight partition wall more cumbersome. Summary of the Invention

[0005] An embodiment of the present invention provides a keel that can arbitrarily adjust the width of the keel within a preset range, thereby meeting the requirements of decoration projects for arbitrarily selecting different keel widths within the preset range.

[0006] To achieve the above object, the embodiment of the present invention adopts the following technical solutions:

[0008] Optionally, the connecting strip is fixedly connected to the side plates. When the side plates are stressed, the connecting strip deforms to change the angle between the connecting strip and the two side edges.

[0009] Optionally, the connecting bar is rotatably connected to the side plate. When the side plate is stressed, the connecting bar rotates relative to the side plate to change the angle between the connecting bar and the two side edges.

[0017] For the keel provided by the embodiment of the present invention, when the side plate is stressed, the angle between the connecting bar and the two side plates will change, that is, the angle between the connecting bar and the side plate can be adjusted between 0° and 90°.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0027] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, a rotatable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Currently, the existing width sequences of the keels, namely 50mm, 75mm, 100mm, and 150mm, limit the thickness selection when using keels to make partition walls. For thicker partition walls or those that must use intermediate sizes, multiple keels need to be stacked for construction layout. Otherwise, it can only be achieved by adjusting the surface panel components. This not only increases the number of keels used but also makes the construction process of the keel framework for the partition wall more cumbersome.

[0030] Based on this, an embodiment of the present invention provides a keel. Referring to Figure 5 , it includes side plates 1 and connecting bars 2. There are two side plates 1, and the two side plates 1 are arranged opposite to and parallel to each other. The two ends of the connecting bar 2 are respectively connected to the two side plates 1 in one-to-one correspondence, and the plane where the connecting bar 2 is located is perpendicular to the side plates 1. Thus, when the side plates 1 are stressed, the angle between the connecting bar 2 and the two side plates 1 will change, that is, the angle between the connecting bar 2 and the side plate 2 can be adjusted between 0° and 90°. As shown in Figure 1 and Figure 2 , through the action of force, the distance between the two side plates 1 can vary between the width a and the length b of the connecting bar 2, so that the distance between the two side plates 1 changes, thereby realizing arbitrary adjustment of the width sequence of the keel within a preset range, and further meeting the requirements of the decoration project for arbitrarily selecting different keel widths within the preset range.

[0031] It should be noted that the direction of this acting force only needs to satisfy that the included angle with the side plate is not zero, and no specific limitation is made. However, in order to make the adjustment of the keel width more convenient and labor-saving, the direction of the acting force is usually at a maximum included angle of 90° with the side plate 1. At this time, the direction of the acting force is consistent with the length direction of the connecting bar 2. When applying an acting force from the two side plates 1 towards the space between the two side plates 1, the angle between the connecting bar 2 and the side plate 1 decreases. Correspondingly, the distance between the two side plates 1 of the keel decreases. When applying an acting force from the two side plates 1 towards the outside of the two side plates 1, the angle between the connecting bar 2 and the side plate increases. Correspondingly, the distance between the two side plates 1 of the keel increases. Thus, arbitrary adjustment of the width sequence of the keel within a preset range is realized.

[0032] Among them, there are various connection methods between the connecting bar 2 and the side plate 1. It can be a fixed connection or a rotatable connection.

[0033] Specifically, as shown in Figure 1 and Figure 2As shown, the connecting bar 2 is fixedly connected to the side plate 1. This fixed connection method can be welding, or an integrally formed structure. It can also be that one end of the connecting bar 2 and the side plate 1 are fixed by more than one fixing structure to form a non-rotatable fixing structure. The fixing structure can be a screw or a rivet, etc. When the side plate 1 is stressed, the connecting bar 2 itself deforms to change the angle between the connecting bar 2 and the side plate 1, thereby changing the distance between the two side plates 1. During this process, in order to enable the connecting bar 2 to have better mechanical properties during deformation, preferably, the material for making the connecting bar 2 can be a ductile metal or non-metal material.

[0034] As Figure 3 shown, the connecting bar 2 is rotatably connected to the side plate 1. When the side plate 1 is stressed, the connecting bar 2 rotates relative to the side plate 1 to change the angle between the connecting bar 2 and the side plate 1, thereby changing the distance between the two side plates 1.

[0035] Among them, the rotatable connection method between the connecting bar 2 and the side plate is: the end of the connecting bar 2 is provided with a plug hole or a positioning post corresponding to the plug hole, and at the position on the side plate 1 corresponding to the end of the connecting bar 2, there is a corresponding positioning post or plug hole. In this way, when the connecting bar 2 and the side plate 1 are installed and connected, the positioning post is inserted into the plug hole. While forming a fixed structure, the end of the connecting bar 2 and the side plate 1 can also rotate around the positioning post, thereby realizing the rotatable connection between the end of the connecting bar 2 and the side plate 1; in addition, the end of the connecting bar 2 can also be directly movably riveted to the side plate 1 by a rivet. In this way, while simplifying the rotatable connection structure, the connection strength between the connecting bar 2 and the side plate 1 can also be increased.

[0036] As Figure 1 and Figure 3 shown, the side plate 1 includes a side plate body 11 and an extension part 12 that is perpendicular to and fixedly connected to the side plate body 11. Specifically, the side plate body 11 and the extension part 12 can be fixed by welding; in addition, the side plate body 11 and the extension part 12 can also be an integral structure, that is, the side plate 1. After a part of one side of the side plate 1 is folded by 90°, it forms the extension part 12, and the rest is the side plate body 11. Among them, the two ends of the connecting bar 2 are respectively connected to the extension parts 12 of the two side plates 1 in a one-to-one correspondence, and the two side plate bodies 11 are arranged opposite to each other and perpendicular to the connecting bar 2 and the extension part 12.

[0037] In order to increase the structural strength of the connection between the two side plates 1, as Figure 1 and Figure 3As shown, there are multiple connecting bars 2. Both ends of the multiple connecting bars 2 are respectively connected to two side plates 1, which increases the strength of the connection structure between the two side plates 1. First, when the number of connecting bars 2 is multiple, if the distance between the two side plates 1 is reduced, the angle between the connecting bar 2 and the side plate 1 decreases. At this time, adjacent connecting bars 2 will approach each other. In this way, multiple connecting bars are arranged at intervals, avoiding the extrusion force between adjacent connecting bars 2, and being able to reduce the resistance when the distance between the two side plates 1 is adjusted downward. Second, since there is an angle between the connecting bar 2 and the side plate 1, when the angle approaches 0°, the distance between the two side plates 1 is the smallest, and when the angle is equal to 90°, the distance between the two side plates 1 is the largest; in order to make the adjustment range between the two side plates 1 the largest, multiple connecting bars 2 are arranged parallel to each other, so that the angle between each connecting bar 2 and the side plate 1 remains the same. In this way, when the angles between all the connecting bars 2 and the side plate 1 vary between 0° and 90° (including 90° but not including 0°), the distance between the side plates 1 has the largest adjustment range.

[0038] When the keel is actually applied, the keel is usually fixed to the corresponding position through fixing parts. In this process, the side plates 1 of the keel will inevitably be subjected to some acting forces. In order to prevent the distance between the two side plates 1 on the keel from changing under the action of the acting forces, the keel further includes a positioning part 3. Both ends of the positioning part are respectively connected to the two side plates, so that the distance between the two side plates 1 remains unchanged, thereby ensuring the stability of the keel structure during application. As Figure 5 shown, after the width of the keel is adjusted to a suitable width sequence, the positioning parts 3 corresponding to the width sequence are respectively connected to the two side plates 1, thereby preventing the side plates 1 from changing the distance between the two side plates 1 after being stressed, causing the width of the keel to change, and ensuring the stability of the keel structure.

[0039] Among them, the positioning part 3 and the two side plates 1 can be fixedly connected or detachably connected. Usually, when fixedly connected, both ends of the positioning part 3 are respectively welded to the two side plates 1. Although the strength of the connection structure is ensured, the operation process is relatively cumbersome. Preferably, the positioning part 3 and the two side plates 1 are detachably connected. For example, through detachable connection methods such as screw fixation, snap fixation or plug-in fixation. In this way, while ensuring the stability of the keel structure, the installation process of the positioning part is simplified, and the keel can adjust the distance between the side plates 1 multiple times, realizing the reuse of the keel.

[0040] Specifically, jacks 4 are respectively provided on the two side plates 1. Correspondingly, both ends of the positioning member 3 can be inserted and matched with the jacks 4, so as to ensure that the distance between the two side plates 1 of the keel will not change. Among them, the setting position and direction of the jacks are not limited herein. For example, the jack 4 can be provided on the side plate body 11, or on the extension part 12, can be provided on the inner side of the side plate 1, or on the outer side of the side plate 1; and the insertion direction of the jack 4 can be parallel to the plane where the position of the side plate 1 provided with the jack 4 is located, can also form an angle with this plane, or even be perpendicular to this plane.

[0041] When the insertion direction of the jack 4 is perpendicular to the side plate 1, there are two cases: the jack 4 is the corresponding opening on the two extension parts 12, and the insertion direction of the jack 4 is perpendicular to the extension part 12. At this time, the positioning member 3 is in a U-shaped structure, and both ends are respectively inserted into the corresponding jacks 4 on the two extension parts 12 to keep the distance between the two side plates unchanged; or it is the corresponding opening on the two side plate bodies 11, and the insertion direction of the jack 4 is perpendicular to the side plate body 11. At this time, the positioning member 3 is set straight and inserted into the corresponding jacks 4 on the two side plate bodies 11, and through a clamping structure, or a fixing structure such as the cooperation of a screw and a nut, the two side plates 1 are respectively fixed and positioned on the straight positioning member 3 to keep the distance between the two side plates unchanged.

[0042] When the insertion direction of the jack 4 is parallel to the side plate 1, there are two cases: such as Figure 4 and Figure 5As shown, the jack 4 is located inside the two side plate bodies 11, and the insertion direction of the jack 4 is parallel to the side plate body 11. At this time, the U-shaped positioning member 3 includes a positioning member body 31 and a plug-in end 32. Specifically, both ends of the positioning member 3 are bent to form a plug-in end 32 perpendicular to the positioning member body 31, and the plug-in end 32 is in plug-in fit with the jack 4, that is, the two plug-in ends 32 are respectively inserted into the corresponding jacks 4 on the two side plate bodies 11 to keep the distance between the two side plates unchanged. In addition, when at least one jack 4 is located outside the side plate body 11, in some cases, the above scheme can also be realized. Or, the jack 4 is located inside or outside the two extension plates 12. Taking the case where the jack 4 is arranged inside the extension part 12 as an example, when the insertion directions of the two jacks 4 arranged on the two extension parts 12 are on a straight line, at this time, the positioning member 3 is arranged straight and inserted into the corresponding two jacks 4 on the two extension parts 12, and through a clamping structure, or a fixing structure such as the cooperation of a thread and a nut, the jacks 4 are respectively fixed and positioned on the straight positioning member 3 to keep the distance between the two side plates unchanged; when the insertion directions of the two jacks 4 arranged on the two extension parts 12 are not on a straight line, at this time, the positioning member 3 is in a U-shaped structure, and both ends are respectively inserted into the corresponding jacks 4 on the two extension parts 12 to keep the distance between the two side plates unchanged. It should be noted that in this scheme, the included angle between the two plug-in ends 32 of the U-shaped positioning member 3 and the positioning member body 31 is not only 90°, but varies between 0 and 180 segments.

[0043] When the insertion direction of the jack 4 is perpendicular to the side plate body 11 or the extension part 12, a hole can be directly opened at the corresponding position; when the insertion direction of the jack 4 is parallel to the side plate body 11 or the extension part 12, the formation of the jack 4 requires fixing a concave structure member on the side plate body 11 or the extension part 12, so that a jack 4 is formed between the structure member and the side plate body 11 or the extension part 12. The concave structure member can be fixed to the side plate body 11 or the extension part 12 by welding or screws.

[0044] To further simplify the setting process of the parallel jacks 4, as Figure 5 shown, a bent part is arranged on the side plate body 11 or the extension part 12. Obviously, the bent part is a part of the side plate body 11 or the extension part 12 and is bent inward to form a jack. In this way, when making the parallel jacks 4, the corresponding position of the side plate body 11 or the extension part 12 can be directly stamped by a machine tool to directly form the structure of the parallel jacks 4. Since the bent part and the side plate 1 are an integral structure, no additional concave structure member and installation process are required, which simplifies the production process of the parallel jacks 4 while the stamping production process is conducive to the industrial production of products.

[0045] Among them, for the jack 4, two corresponding ones on the two side plates 1 are in a group and are adapted to one positioning member. In order to further increase the structural strength between the keel side plates, along the extending direction of the keel, multiple groups of jacks are distributed at intervals for increasing the overall structural strength of the keel.

[0046] In the description of this specification, the specific features, materials or characteristics may be combined in any one or more embodiments or examples in a suitable manner.

[0047] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
