Description

Technical Field

[0001] The present invention relates to a combined partition light steel keel. Background Art

[0002] In the existing partition light steel keels, the vertical keels play a load-bearing role, and their widths determine the thickness of the formed wall. The only width sequences of 50, 75, 100, 150, etc. not only limit the selection of wall thickness, but for thicker walls or walls that must use intermediate sizes, multiple keels need to be stacked, otherwise only the adjustment of the surface panel can be used to achieve it. This not only increases the steel consumption unnecessarily, but also raises the overall cost. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems and provide a combined partition light steel keel with adjustable thickness.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A combined partition light steel keel includes a plurality of vertically arranged vertical keel units spaced apart from each other. Each vertical keel unit includes two vertical keels, the grooves of the two vertical keels face each other and are spaced apart. Several vertically spaced connectors are connected between the two vertical keels. By using connectors of different lengths, vertical keel units of different thicknesses can be obtained. The connector includes an upper U-shaped plate and a lower U-shaped plate. The bottom plates and the two side plates of the upper U-shaped plate and the lower U-shaped plate are all vertical. The upper bottom plate of the upper U-shaped plate and the lower bottom plate of the lower U-shaped plate are connected by a vertical plate. A support wide plate is connected to one free end of the upper bottom plate and the lower bottom plate of the connector.

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 corresponding bottom plates of 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 corresponding longitudinal connecting plates of the two vertical keels of the vertical keel unit.

[0009] When the arranged vertical keel units need to be connected by a horizontal keel, the bottom of the horizontal keel is lapped with the support wide plate of the connector.

[0010] A combined partition light steel keel includes a number of vertically arranged and spaced-apart vertical keel units. Each vertical keel unit includes two vertical keels, the slots of the two vertical keels are opposite and spaced apart, and several vertically spaced connecting pieces are connected between the two vertical keels. By using connecting pieces of different lengths, vertical keel units of different thicknesses can be obtained. A support rod is connected between two adjacent connecting pieces or between the two vertical keels between two adjacent connecting pieces. The connecting piece includes a U-shaped plate, and one of the top or bottom ends of the bottom plate of the U-shaped plate is connected to a support wide plate, and a narrow reinforcing plate is provided at the top or bottom end of the bottom plate corresponding to the support wide plate.

A transverse connecting plate opposite to the bottom plate is connected to the free end of the side plate, and the transverse connecting plate is within the bottom plate. An L-shaped opening is formed between the transverse connecting plate and the longitudinal connecting plate.

[0012] The two side plates of the U-shaped plate are connected to the two corresponding bottom plates of the two vertical keels. The support rod includes a vertically inclined long support rod and a horizontally longitudinal short support rod. The long support rod and the short support rod are in an L shape. The long support rod includes a side section A, a connecting section C, and a side section B. The short support rod includes a side section a, a connecting section c, and a side section b. The free end of the side section B is connected to the free end of the side section b through a vertical connecting section.

The side section a of the short support rod corresponds to the side section A of the long support rod and is connected to the bottom plate of the one vertical keel.

[0013] Insertion slots are respectively provided between the wide support plate, the narrow reinforcing plate and the side plates of the U-shaped plate. The two side plates of the U-shaped plate are connected to the two corresponding bottom plates of the two vertical keels. The support rod is connected to two adjacent connecting pieces. The support rod includes an upper vertical rod, an inclined connecting rod, and a lower vertical rod. The upper vertical rod and the lower vertical rod respectively pass through the connecting pieces through two insertion slots that are adjacent up and down and diagonal, and are welded to the bending part of the connecting piece where the side plate and the bottom plate of the U-shaped plate are located.

[0014] When the arranged vertical keel units need to be connected by a horizontal keel, the bottom of the horizontal keel is lapped with the support wide plate of the connecting piece.

[0015] A combined partition light steel keel includes a number of vertically arranged keel units at intervals. Each vertical keel unit includes two vertical keels. The slots of the two vertical keels face each other and are arranged at intervals. Several vertically spaced connecting pieces are connected between the two vertical keels. By using connecting pieces of different lengths, vertical keel units of different thicknesses can be obtained. The connecting piece includes a connecting body and a flat tongue plate. The connecting body includes two wide concave plates and a narrow concave plate connected between the two wide concave plates. The bottom plate of the narrow concave plate protrudes inward from the bottom plates of the upper and lower wide concave plates towards the concave opening. The flat tongue plate is connected to the top wall of the bottom plate of the upper wide concave plate. The direction of the flat tongue plate is opposite to the side plate of the connecting plate body. A reinforcing narrow plate corresponding to the flat tongue plate is connected to the bottom wall of the bottom plate of the lower wide concave plate.

[0016] The vertical keel includes an L-shaped keel body. The keel body includes a bottom plate and a side plate.

[0018] When the arranged vertical keel units need to be connected by a horizontal keel, the bottom of the horizontal keel is lapped with the flat tongue plate of the connecting piece.

[0019] The vertical keel can be a U-shaped light steel keel or a C-shaped light steel keel.

[0020] The gap between the two vertical keels of the vertical keel unit and the connecting piece can be used as a channel for laying pipelines. A support keel is connected between the two horizontally adjacent vertical keels at the position where a junction box needs to be installed or installed on the horizontal keel. The junction box is connected to the pipeline passing through the channel.

[0021] The combined partition light steel keel also includes a keel door and window opening. The keel door and window opening includes two groups of vertical keel units at intervals. 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 keel unit A includes two opposite vertical keels A. Connecting pieces are respectively connected to the top and bottom of the two vertical keels A. The connecting pieces of the vertical keel unit A are flush with the connecting pieces of the two side groups of vertical keel units. Several horizontal keels are installed on the flush connecting pieces.

[0022] Advantages of the present invention: The present invention aims to combine two vertical keels with connectors of different sizes, enabling the width of the vertical keel to be adjusted arbitrarily according to the required wall thickness, thereby fixing the materials used for the surface layer; at the same time, reducing the steel consumption of the wider vertical keel. That is, when the thickness of the vertical keel unit is 100 mm, the present invention saves one-fifth of the steel beam consumption compared with the 100-width light steel keel used in the prior art. When the thickness of the vertical keel unit is 200 mm, the present invention saves one-half of the steel beam consumption compared with the 200-width light steel keel used in the prior art. Further, on-site, since various processes such as multiple installations of keels, drilling wire holes, and adjusting panels are cancelled, the assembly working hours are reduced even more; at the same time, the workload of design, procurement, and on-site organization is reduced.

[0037] The following only uses embodiments to illustrate possible implementation modes of the present invention, but is not used to limit the scope to be protected by the present invention. First, it is stated.

[0038] As Figure 1 shown, the first embodiment of the present invention is a composite partition light steel keel, including a plurality of vertically arranged vertical keel units 1 arranged at intervals. The vertical keel unit includes two vertical keels 11, the slots of the two vertical keels 11 face each other and are arranged at intervals, and several vertically spaced connecting members 12 are connected between the two vertical keels 11. By using connecting members of different lengths, vertical keel units of different thicknesses can be obtained. The vertical keel can be selected as C-shaped or U-shaped or other structures. In this embodiment, the vertical keel is preferably the following structure: As Figure 6 shown, the vertical keel 11 includes an L-shaped keel body, the keel body 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. A transverse connecting plate 114 opposite to the bottom plate 111 is connected to the free end of the side plate 112. 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; As Figure 1AAs shown, the connector 12 includes an upper U-shaped plate 121 and a lower U-shaped plate 122. The bottom plates and the two side plates of the upper U-shaped plate 121 and the lower U-shaped plate 122 are all 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 of the upper U-shaped plate, and the lower bottom plate of the lower U-shaped plate form a horizontally placed H shape. At one free end of either the upper bottom plate or the lower bottom plate of the connector, a support wide plate 124 is connected, and at the other free end, a reinforcing narrow plate 125 corresponding to the support wide plate is connected. The reinforcing narrow plate 125 can improve the rigidity of the connector 12. The front and rear ends of the connector 12 are inserted into the grooves of the corresponding vertical keels through L-shaped openings. The two side plates 1212 of the upper U-shaped plate and the two side plates 1222 of the lower U-shaped plate are connected to the two bottom plates 111 corresponding to the two vertical keels of the vertical keel unit. In addition to horizontally determining the thickness of the keel wall, the connector also has an indispensable function, that is, to minimize the bending of the keel when it is subjected to lateral pressure in the wall direction. When both the upper and lower ends of the connector are fixed, it is equivalent to an X-shaped support and can play a role in resisting bending. The connector can also save at least more than half of the materials.

[0039] Further, when the arranged vertical keel units need to be connected by a horizontal keel 13, the horizontal keel is U-shaped, and the bottom plate of the horizontal keel overlaps with the support wide plate 124 of the connector 11.

[0040] Further, the gap between the two vertical keels 11 of the vertical keel unit and the connector 12 can be used as a channel for laying pipelines. Between the two horizontally adjacent vertical keels at the position where the junction box needs to be installed, a support keel is connected or the junction box is directly installed on the horizontal keel 13. The junction box 14 is connected to the pipelines passing out of the channel.

[0041] Further, the combined partition light steel keel also includes a keel door and window opening 15. The keel door and window opening includes two groups of spaced vertical keel units. Each group of vertical keel units includes two vertical keel units. A vertical keel unit A151 is installed in the middle of the non-opening positions of the two groups of vertical keel units. Connectors 12 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 two side groups of vertical keel units. Several horizontal keels 13 are installed on the flush connectors; for a window or door opening width less than the interval between the partition vertical keel units and no openable window or door components are installed in the opening, this structure may not be adopted either.

[0042] As Figure 2 and Figure 2AAs shown, this is the second embodiment of the present invention. The difference from the first embodiment lies in the different connection parts between the connecting member and the vertical keel. 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.

[0043] As Figure 3 shown, this is the third embodiment of the present invention, a combined partition light steel keel, including a number of vertically arranged vertical keel units spaced apart. The vertical keel unit 1 includes two vertical keels 11, the slots of the two vertical keels face each other and are arranged at intervals, and several vertically spaced connecting members 12A are connected between the two vertical keels. By using connecting members 12A of different lengths, vertical keel units of different thicknesses can be obtained. In this embodiment, the vertical keel can be selected as C-shaped, U-shaped or other structures. In this embodiment, the vertical keel is the preferred vertical keel structure of the first and second embodiments: 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. A transverse connecting plate 114 opposite to the bottom plate 111 is connected to the free end of the side plate 112. 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; a support rod 12a is connected between the two vertical keels between two adjacent connecting members. As Figure 3A and Figure 3B shown, the connecting member 12A includes a U-shaped plate 12A1, and one of the top or bottom ends of the bottom plate of the U-shaped plate is connected to a support wide plate 12A2, and a narrow reinforcing plate 12A3 is provided at the top or bottom end of the bottom plate corresponding to the support wide plate 12A2; the two side plates of the U-shaped plate 12A1 are connected to the two bottom plates 111 corresponding to the two vertical keels 11. The support rod 12a includes a vertically inclined long support rod 12a1 and a horizontally longitudinal short support rod 12a2. The long support rod 12a1 and the short support rod 12a2 are in a [ shape. The long support rod includes a side section A, a connecting section C and a side section B. The short support rod includes a side section a, a connecting section c and a side section b. The free end of the side section B is connected to the free end of the side section b through a vertical connecting section 12a3. The side section A of the long support rod is welded to the bottom plate of a vertical keel of the vertical keel unit. The side section B of the long support rod, the vertical connecting section and the side section a of the short support rod are welded to the bottom plate of the other vertical keel. The side section a of the short support rod corresponds to the side section A of the long support rod and is welded to the bottom plate of a vertical keel. In this application, the support rod can have various structures and the connection with the vertical keel can have various ways. The main function is to play a bending resistance role on the vertical keel while ensuring more material saving; the support rod structure of this embodiment has better bending resistance and less material consumption. The degree of standardization of parts manufacturing is higher during the process of customizing the wall thickness.

[0044] Further, when the vertical keel units need to be connected by the horizontal keel 13, the horizontal keel is U-shaped, and the bottom plate of the horizontal keel overlaps with the supporting wide plate 12A2 of the connecting member 12A.

[0045] Further, the gap between the two vertical keels 11 of the vertical keel unit and the connecting member 12A can be used as a channel for laying pipelines. Between two horizontally adjacent vertical keels at the position where a junction box needs to be installed, a supporting keel is connected or the junction box is directly installed on the horizontal keel 13, and the junction box 14 is connected to the pipelines passing out of the channel.

[0046] Further, the combined partition light steel keel further 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. A vertical keel unit A151 is installed in the middle of the non-opening positions of the two groups of vertical keel units. The connecting member 12A is connected to the top and bottom ends of the two vertical keels A respectively. The connecting members of the vertical keel unit A are flush with the connecting members of the two side groups of vertical keel units. Several horizontal keels 15 are installed on the flush connecting members. When the width of the opening is less than the interval between the partition vertical keel units and no openable door and window components are installed in the opening, this structure may not be adopted either.

[0047] As Figure 4 and Figure 4A shown, this is the fourth embodiment of the present invention. The difference from the third embodiment lies in the structure of the support rod. Insertion slots are respectively provided between the wide support plate, the narrow reinforcement plate and the side plates of the U-shaped plate. The two side plates of the U-shaped plate are connected to the corresponding two bottom plates of the two vertical keels. The support rod 12b is connected to two adjacent connecting members 12A. The support rod 12b includes an upper vertical rod, an inclined connecting rod and a lower vertical rod. The upper vertical rod and the lower vertical rod pass through the connecting member 12A through two insertion slots that are vertically adjacent and diagonal respectively and are welded to the bending positions of the side plates and the bottom plates of the U-shaped plate.

[0048] As Figure 5 、 Figure 5A and Figure 5BAs shown in the figure, this is the fifth embodiment of the present invention, a combined partition light steel keel, which includes several vertically arranged keel units arranged at intervals. The vertical keel unit 1 includes two vertical keels 11, the notches of the two vertical keels 11 face each other and are arranged at intervals, and several vertically spaced connectors 12B are connected between the two vertical keels. By using connectors of different lengths, vertical keel units of different thicknesses can be obtained. The vertical keel is the preferred structure of the above embodiment. The connector 12B includes a connection body 12B1 and a flat tongue plate 12B2. The connection body 12B1 includes two wide concave plates and a narrow concave plate connected between the two wide concave plates. The bottom plates of the upper and lower wide concave plates and the bottom plate of the narrow concave plate are connected. The bottom plate of the narrow concave plate protrudes inward from the bottom plates of the upper and lower wide concave plates toward the concave opening. The flat tongue plate 12B2 is connected to the top wall of the bottom plate of the upper wide concave plate. The direction of the flat tongue plate is opposite to the side of the connecting plate body. A reinforcing narrow plate corresponding to the flat tongue plate is connected to the bottom wall of the bottom plate of the lower wide concave plate. The two side plates of the wide concave plate are attached to the opposite walls of the two transverse connecting plates 114 of the vertical keel unit, and the two side plates of the narrow concave plate are clamped between the opposite walls of the two transverse connecting plates 114.

[0049] Further, when the arranged vertical keel units need to be connected by a horizontal keel 13, the horizontal keel is U-shaped, and the bottom plate of the horizontal keel is lapped with the flat tongue plate 12B2 of the connector 12B.

[0050] Further, the gap between the two vertical keels 11 of the vertical keel unit and the connector 12 can be used as a channel for laying pipelines. A support keel 15 is connected between two horizontally adjacent vertical keels at the position where a junction box (not shown in the figure) needs to be installed, or the junction box is directly installed on the horizontal keel 13. The junction box is connected to the pipelines passing through the channel.

[0051] Further, the combined partition light steel keel of the present invention further includes a keel door and window opening (not shown in the figure). The keel door and window opening includes 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 in the middle of the non-opening positions of the two groups of vertical keel units. Connectors are respectively connected to the top and bottom of the two vertical keels A. The connectors of the vertical keel unit A are flush with the connectors of the two side groups of vertical keel units. Several horizontal keels are installed on the flush connectors. When the width of the opening is less than the interval between the vertical keel units of the partition wall and no openable door and window components are installed in the opening, this structure may not be adopted either.

[0052] Advantages of the present invention:

[0053] 1. Conventional light steel keels have specifications, so the corresponding wall thickness is also limited. However, the width of the combined keel can be customized arbitrarily, which means that with a set of processes and molds, walls of any thickness can be obtained;

[0054] 2. The material between the flanges on both sides of the conventional keel is redundant, and a thicker wall results in material waste. However, for the keel composed of connectors, the void part represents material savings, which also means a reduction in overall cost;

[0055] 3. Although the number of parts and the assembly process are increased, the standardization degree of these parts is very high. Therefore, the combined keel can achieve large-scale and efficient production. Even for the connectors whose lengths need to be changed according to the wall thickness, they can be processed by combining molds. Accordingly, the proportion of the increased processing cost in the total cost is almost negligible;

[0056] 4. The combined keel forms pores that can pass through the keel itself during manufacturing, thus eliminating the need for processes such as drilling during wiring.

[0057] From an engineering perspective, only by adjusting the processing technology parameters can we replace the method of increasing the number of gypsum board layers on the surface of the keel in traditional construction to adjust the wall thickness. The cost reduction is not only the saved steel, but also the gypsum board outside the single layer and the labor cost of laying more gypsum boards on site. Moreover, due to the sufficient void in the middle of the combined keel, the laying of pipelines does not require drilling holes in the keel. Therefore, taking a wall with a thickness exceeding 150mm that cannot be completed by directly pasting a single layer of board on the surface of the standard keel as an example, the engineering cost can be saved by half or more.
