Abstract
Description
[0001] This invention is a divisional application of the invention patent application with application number 202010571222.4, application date June 22, 2020, and invention name “Combined partition wall light steel keel”. Technical Field
[0002] The invention relates to a combined light steel keel for partition walls. Background Art
[0003] The vertical studs in existing light-gauge steel partition walls bear the weight, and their width determines the thickness of the wall. The limited widths of 50, 75, 100, and 150 mm not only restrict the choice of wall thickness, but also require stacking multiple studs for thicker walls or adjusting the surface panels. This unnecessarily increases steel usage and overall costs. Summary of the Invention
[0004] The purpose of the present invention is to solve the above technical problems and provide a thickness-adjustable combined partition wall light steel keel.
[0005] To achieve the above object, the present invention adopts the following technical solutions: A modular partition wall light steel keel comprises a plurality of vertical keel units arranged at intervals, wherein the vertical keel unit comprises two vertical keels, the notches of the two vertical keels being opposite and spaced apart, a plurality of vertically spaced connectors being connected between the two vertical keels, and vertical keel units of different thicknesses being obtained by using connectors of different lengths, the connectors comprising an upper U-shaped plate and a lower U-shaped plate, the bottom plates and side plates of the upper U-shaped plate and the lower U-shaped plate being vertical, the upper bottom plate of the upper U-shaped plate and the lower bottom plate of the lower U-shaped plate being connected by a vertical plate, and a supporting wide plate being connected to one of the free ends of the upper bottom plate and the lower bottom plate of the connector; The vertical keel can be a U-shaped light steel keel or a C-shaped light steel keel; The gap between the two vertical keels and the connecting piece of the vertical keel unit can be used as a channel for laying pipelines. A supporting keel is connected between two transversely adjacent vertical keels where a junction box is to be installed, or is installed on the transverse keel. The junction box is connected to the pipeline passing through the channel. The combined partition wall light steel keel also includes keel door and window openings, which include two groups of spaced vertical keel units. Each group of vertical keel units includes two vertical keel units. A vertical keel unit A is installed between the non-opening positions of the two groups of vertical keel units. The vertical keel unit A includes two opposite vertical keels A. Connectors are respectively connected to the top and bottom ends of the two vertical keels A. The connectors of the vertical keel unit A are flush with the connectors of the vertical keel units on both sides, and several horizontal keels are installed on the flush connectors.
[0006] Preferably, the vertical keel includes an L-shaped keel body, which includes a bottom plate and a side plate. The free end of the bottom plate is connected to a longitudinal connecting plate opposite to the side plate, and the longitudinal connecting plate is inside the side plate. The free end of the side plate is connected to a transverse connecting plate opposite to the bottom plate, and the transverse connecting plate is inside the bottom plate. An L-shaped opening is formed between the transverse connecting plate and the longitudinal connecting plate.
[0007] The two side plates of the upper U-shaped plate and the two side plates of the lower U-shaped plate are connected to the two bottom plates corresponding to the two vertical keels of the vertical keel unit.
[0008] The two ends of the bottom plate of the upper U-shaped plate and the two ends of the bottom plate of the lower U-shaped plate are respectively connected to the two longitudinal connecting plates corresponding to the two vertical keels of the vertical keel unit.
[0009] When the arranged vertical keel units need to be connected through a transverse keel, the bottom of the transverse keel overlaps the supporting wide plate of the connecting member; The beneficial effects of the present invention are as follows: The present invention utilizes two vertical purlins in combination with connectors of varying sizes, allowing the width of the vertical purlins to be adjusted to the required wall thickness, thereby securing the surface material. This also reduces the steel consumption of the wider vertical purlins. Specifically, when the vertical purlin unit is 100 mm thick, the present invention saves one-fifth the steel beams used compared to the 100 mm wide light steel purlins used in the prior art. When the vertical purlin unit is 200 mm thick, the present invention saves one-half the steel beams used compared to the 200 mm wide light steel purlins used in the prior art. Furthermore, by eliminating multiple on-site purlin installation processes, such as threading holes, panel adjustment, and other steps, assembly time is further reduced, while also reducing the workload associated with design, procurement, and on-site organization.

[0014] Figure 2A for Figure 2 A partial enlarged view of the . DETAILED DESCRIPTION
[0015] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of the present invention.
[0016] like Figure 1 and Figure 1A As shown, the first embodiment of the present invention is a combined partition wall light steel keel, including a plurality of vertical keel units 1 arranged at intervals, the vertical keel unit including two vertical keels 11, the notches of the two vertical keels 11 are opposite and arranged at intervals, and a plurality of vertically spaced connecting pieces 12 are connected between the two vertical keels 11, and vertical keel units of different thicknesses are obtained by connecting pieces of different lengths. The vertical keel may be C-shaped, U-shaped or other structures. In this embodiment, the vertical keel is preferably structured as follows: the vertical keel 11 includes an L-shaped keel body, which includes a bottom plate 111 and a side plate 112. A longitudinal connecting plate 113 opposite to the side plate 112 is connected to the free end of the bottom plate 111. The longitudinal connecting plate 113 is within the width of the side plate 112. The free end of the side plate 112 is connected to a transverse connecting plate 114 opposite to the bottom plate 111. The transverse connecting plate 114 is within the width of the bottom plate. An L-shaped opening is formed between the transverse connecting plate 114 and the longitudinal connecting plate 113. Figure 1A As shown, the connecting member 12 includes an upper U-shaped plate 121 and a lower U-shaped plate 122, the bottom plates and two side plates of the upper U-shaped plate 121 and the lower U-shaped plate 122 are both vertical, the upper bottom plate 1211 of the upper U-shaped plate 121 and the lower bottom plate 1221 of the lower U-shaped plate 122 are connected by a vertical plate 123, the upper bottom plate 1211 of the upper U-shaped plate, the lower bottom plate 1221 of the lower U-shaped plate and the vertical plate 123 are vertically aligned, the upper bottom plate, the vertical plate and the lower bottom plate of the upper U-shaped plate form a horizontal H-shape, a supporting wide plate 124 is connected to the free end of one of the upper bottom plate and the lower bottom plate of the connecting member, and a reinforcing narrow plate 125 corresponding to the supporting wide plate is connected to the other free end, and the reinforcing narrow plate 125 can improve the rigidity of the connecting member 12. The front and rear ends of the connector 12 are inserted into the corresponding slots of the vertical purlins through the L-shaped opening. The side panels 1212 of the upper U-shaped plate and the side panels 1222 of the lower U-shaped plate are connected to the two base panels 111 corresponding to the two vertical purlins of the vertical purlin unit. In addition to determining the thickness of the purlin wall laterally, this connector also serves an essential function: minimizing bending of the purlin when subjected to lateral pressure in the direction of the wall. When both ends of the connector are fixed, it acts as an X-shaped support, providing bending resistance. This connector can also save at least half of the material.
[0017] Furthermore, when the arranged vertical keel units need to be connected via a transverse keel 13 , the transverse keel is U-shaped, and the transverse keel bottom plate overlaps the supporting wide plate 124 of the connecting member 11 .
[0018] Furthermore, the gap between the two vertical purlins 11 and the connecting piece 12 of the vertical purlin unit can be used as a channel for laying pipelines. A supporting purlin is connected between two adjacent vertical purlins in the transverse direction where a junction box is to be installed, or the junction box is directly installed on the transverse purlin 13. The junction box 14 is connected to a pipeline passing through the channel.
[0019] Furthermore, the combined partition wall light steel keel also includes a keel door and window opening 15, which includes two groups of spaced vertical keel units, each group of vertical keel units includes two vertical keel units, and a vertical keel unit A151 is installed in the middle of the non-opening position of the two groups of vertical keel units, and the top and bottom ends of the two vertical keels A are respectively connected with the connecting parts 12. The connecting parts of the vertical keel unit A are flush with the connecting parts of the vertical keel units on both sides, and several horizontal keels 13 are installed on the flush connecting parts; when the opening width is smaller than the spacing between the vertical keel units of the partition wall, and when no openable door and window components are installed in the hole, this structure may not be adopted.
[0020] like Figure 2 and Figure 2A The second embodiment of the present invention is shown in FIG. 1 , which differs from the first embodiment in that the connection portion between the connector and the vertical keel is different. In this embodiment, the two ends of the bottom plate of the upper U-shaped plate and the two ends of the bottom plate of the lower U-shaped plate are respectively connected to the two longitudinal connecting plates corresponding to the two vertical keels of the vertical keel unit. Advantages of the present invention: 1. Conventional light steel keels have specifications, so the corresponding wall thickness is also limited by them. However, the width of the modular keel can be customized, which means that with a set of processes and molds, walls of any thickness can be obtained; 2. Conventional keels have redundant material between the two sides of the fold, resulting in material waste for thicker walls. However, keels made of connectors save material in the gaps between the two sides, which also means lower overall costs. 3. Although the number of parts and assembly processes increases, these parts are highly standardized, allowing modular keels to be produced efficiently on a large scale. Even connectors that need to change length according to wall thickness can be processed using modular molds. Accordingly, the increased processing costs account for a negligible proportion of the total cost. 4. The composite keel forms a hole that can pass through the keel itself during manufacturing, thus eliminating the need for drilling and other processes required for wiring.
[0021] From an engineering perspective, simply adjusting processing parameters can replace the traditional method of adding layers of gypsum board to the stud surface to adjust wall thickness. This reduces costs not only by saving a small amount of steel, but also by saving on additional layers of gypsum board and the labor costs of laying additional gypsum boards on site. Furthermore, the ample gap in the center of the composite stud eliminates the need for drilling holes in the stud for plumbing. Therefore, for walls over 150mm thick, where a single layer of board cannot be directly applied to the standard stud surface, project costs can be reduced by half or even more.
