Description

Technical Field

[0001] The invention relates to the technical field of scaffolding, in particular to a plug-in scaffolding. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to the different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding. In order to reuse as much as possible, most of the existing scaffoldings are made of steel pipes.

[0003] The existing steel pipe scaffolding uses a clamp during construction to fix two adjacent steel pipes, and the bolts between the clamps need to be tightened with tools, which is inconvenient to operate. Therefore, a plug-in scaffolding has emerged, which connects the two by setting a connecting plate on the side wall of the steel pipe, and the preset connectors at the ends of the horizontal steel pipes cooperate with the connecting plate. However, the connecting plate is directly welded to the side wall of the steel pipe. During the transportation of the steel pipes, there are a lot of gaps between the steel pipes, and the transportation space cannot be fully utilized. The ends of the adjacent vertical steel pipes also need another connecting structure to connect. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a plug-in scaffold, including columns and crossbars, and supporting feet and / or first connecting pieces matched at the ends of the columns, and second connecting pieces for connecting the crossbars and the first connecting pieces. When in use, a specific scaffold structure is built according to needs. Furthermore, the columns are force-bearing parts in the vertical direction, and the crossbars are used to maintain the connection between the columns to improve the stability of the support. Therefore, the diameter of the crossbar is smaller than the diameter of the columns. When necessary for transportation, it is also convenient to place the crossbars inside the columns for transportation together, thereby improving transportation efficiency.

[0005] The first connector includes a third plug rod, which is plugged into the end of the column. That is, the first connector is used for plug-in connection between two columns. It needs to be ensured that the length of the third plug rod plugged into the column is long enough to maintain the stability of the connection between the two columns.

[0006] The middle of the third plug rod is fixedly connected with a connection plate, and a plurality of insertion holes are arranged at equal angles on the connection plate. The second connecting member includes a second plug rod and a threaded section that are rotatably connected to each other. The second plug rod is fitted in the insertion hole, and the threaded section is threadedly connected to the end of the cross bar. That is, the second connecting member is fixedly connected to the cross bar by threaded connection. After the second connection is removed, the cross bar and the column are a complete tubular member. After the second plug rod is inserted into the insertion hole, the connection between the first connecting member and the second connecting member is realized, and then the connection between the cross bar and the column is realized.

[0007] Preferably, the support foot comprises an O-shaped member, and the upper and lower parts of the O-shaped member are respectively vertically fixedly connected with a first screw and a second screw, the thread directions of the first screw and the second screw are opposite, the first screw is matched with a first connecting sleeve, and the second screw is matched with a second connecting sleeve. That is, by rotating the O-shaped member, the height adjustment of the support foot is achieved through the matching relationship between the first screw, the second screw, the first connecting sleeve and the second connecting sleeve, which is conducive to the stable construction of the scaffolding. At the same time, for adjustment, a rod-type workpiece can be directly inserted into the middle part of the O-shaped member and used as a handle to rotate the O-shaped member. This method is more convenient for height adjustment.

[0008] Preferably, the lower end of the first connecting sleeve is fixedly connected to a bottom plate, and the bottom plate is provided with a plurality of through holes for supporting the upper structure, and the plurality of through holes can be used to insert components such as expansion bolts to position the bottom plate.

[0009] Preferably, the upper end of the second connecting sleeve is fixedly connected with a first plug rod, and the first plug rod is plugged into the end of the column, that is, the upper end of the supporting foot is plugged into the end of the column through the first plug rod, so that the fixed connection between the two is achieved.

[0010] Preferably, one end of the second plug rod is fixedly connected to the second connecting rod, one end of the threaded section is fixedly connected to the first connecting rod, the ends of the first connecting rod and the second connecting rod overlap, and a rotating shaft is interlaced and rotatably arranged. That is, the two sides of the second connecting member are rotatably connected, and when the crossbar is built, it can be built in a horizontal or inclined manner, which increases the diversity of the crossbar arrangement.

[0011] Preferably, a pin hole is provided at the end of the second plug rod, into which a pin can be inserted to prevent the second plug rod from falling out of the plug hole, and this arrangement improves the stability of the scaffolding construction.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The columns are fixedly connected by a first connecting piece, and the connecting plate is arranged on the first connecting piece, so the column is a tubular piece with a constant cross-sectional shape. When the columns are stacked, the gap space generated is as small as possible, which is conducive to transportation.

[0014] 2. Support feet are provided to adjust the support height. Specifically, a rod-shaped tool can be inserted into the O-shaped part to serve as a handle, and the O-shaped part can be rotated to adjust the height, which has the advantage of easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

Further, in order to reduce the weight of the second connector 5 and ensure the connection strength, the third plug rod 51 can be hollowed out, and the third plug rod 51 is plugged into the end of the column 2. It should be noted that the length of the third plug rod 51 inserted into the column 2 should ensure the stability of the connection between the two.

[0026] A connecting plate 52 is fixedly connected to the middle part of the third plug rod 51, and a plurality of insertion holes 53 are arranged at equal angles on the connecting plate 52. The second connecting member 4 includes a second plug rod 42 and a threaded section 43 which are rotatably connected to each other.

The threaded section 43 is threadedly connected to the end of the cross bar 3, that is, the second connecting member 4 and the cross bar 3 are fixedly connected by a threaded connection. Therefore, the cross bar 3 and the first connecting member 5 are connected through the second connecting member 4, and the second connecting member 4 and the cross bar 3 are threadedly connected, which facilitates disassembly and assembly while also ensuring the strength of the connection between the two.

[0028] The lower end of the first connecting sleeve 12 is fixedly connected with a bottom plate 11, and a plurality of through holes are provided on the bottom plate 11. The bottom plate 11 is used to improve the stability of the support, and the through holes are provided with fixing pieces to pass through and limit and fix the bottom plate.

That is, the first plug rod 17 and the third plug rod 51 have the same structural dimensions, so as to realize the connection between the supporting foot 1 and the column 2.

[0030] like Figure 4 As shown, one end of the second plug rod 42 is fixedly connected to the second connecting rod 46, and one end of the threaded section 43 is fixedly connected to the first connecting rod 44. The ends of the first connecting rod 44 and the second connecting rod 46 overlap, and a rotating shaft 45 is interspersed and rotatably arranged. Through this arrangement, the second plug rod 42 and the threaded section 43 are rotatably connected, and the cross bar 3 connected thereto is not limited to being in a horizontal state when the scaffold is erected.
