It is mainly composed of a number of vertical poles, a number of horizontal poles and a corresponding number of connectors. According to the difference in the structure of the connectors, the support frame can be classified into different types such as fastener-type support frames, bowl-type support frames and disc-type support frames.

[0032] The vertical pole assembly includes a plurality of coaxially arranged first vertical poles 1, and first connecting sleeves 2 are respectively provided at the corresponding end positions between two adjacent first vertical poles 1. The lower end of the first vertical pole 1 located above the first connecting sleeve 2 is inserted into the upper inner cavity thereof, and the upper end of the first vertical pole 1 located below the first connecting sleeve 2 is inserted into the lower inner cavity thereof.

When using it, firstly, the spacing between the two groups of vertical pole assemblies is determined according to the actual situation of the construction in accordance with the specifications for erecting the support frame, and then the length of the adjustable crossbar assembly is determined. After the length adjustment of the adjustable crossbar assembly is completed, the corresponding end of the adjustable crossbar assembly is fixedly connected with the first connecting sleeve 2 to achieve a fixed connection between the adjustable crossbar assembly and the vertical pole assembly, thereby finally connecting to form an overall structure of the support frame capable of supporting the formwork.

In this way, when the connecting block 3 is rotated, under the threaded connection relationship between the adjusting bolt 4 and the second connecting sleeve 5, the second connecting sleeve 5 can be moved along the adjusting bolt 4, thereby driving the connecting cross bar 6 and the third connecting sleeve 7 to move accordingly, thereby adjusting the length of the overall structure of the adjustable cross bar assembly. There are four connecting bolts 8, and the third connecting sleeve 7 is threadedly connected to the corresponding connecting bolts 8, so that the overall structure of the adjustable cross bar assembly is firmly fixed and connected to the first connecting sleeve 2, thereby realizing the integrated connection between each adjustable cross bar assembly and each upright assembly.

[0044] In order to ensure that the first vertical pole 1 is uniformly stressed as a whole, the utility model further uses the second reinforcing connecting rod 12 to fix the connecting cross bar 6 to the middle section of the first vertical pole 1 located therebelow, and can further strengthen the stress-bearing structure of the middle portion of the first vertical pole 1. At the same time, the two ends of the second reinforcing connecting rod 12 are connected by bolts and nuts to achieve fixed connection with the third mounting portion 13 and the fourth mounting portion 14.

[0045] In any of the above schemes, it is preferred that a first fastener connecting portion 15 is protrudingly formed on the circumferential outer wall of the upper end of the first vertical rod 1, and the annular top of the first fastener connecting portion 15 presses against the lower end of the first connecting sleeve 2 at the corresponding position, and also includes a first fastener 16, and the inner surface of the first fastener 16 presses against the first fastener connecting portion 15 and the circumferential outer wall of the lower part of the first connecting sleeve 2.

At the same time, the outer diameter of the first fastener connecting portion 15 is equal to the outer diameter of the first connecting sleeve 2, so that the circumferential outer wall of the first fastener connecting portion 15 can be kept flush with the circumferential outer wall of the first connecting sleeve 2, and then the first fastener 16 can be snapped together on the first fastener connecting portion 15 and the lower end of the first connecting sleeve 2, thereby playing a role in fixing the connection relationship between the first vertical pole 1 and the corresponding first connecting sleeve 2.

[0047] The first fastener 16 is an annular structure as a whole, which includes two semi-cylindrical snap-fitting parts, and the ends on the same side of the two are movably connected by a pin shaft, and the corresponding ends on the other side of the two are further fixedly connected by matching bolts and nuts, thereby realizing the snap-fitting effect of the first fastener 16 on the first vertical pole 1 and the first connecting sleeve 2.

[0050] Specific working principle:

[0051] The operator first connects the first vertical poles 1 coaxially through the first connecting sleeve 2, and fixes the first vertical pole 1 and the first connecting sleeve 2 through the first fastener 16 and the second fastener 18, so as to ensure the stability of the support frame vertical pole structure. Then, in accordance with the support frame erection specifications, the spacing between the vertical poles is determined according to the actual situation of the construction, and then the length of the adjustable crossbar assembly is determined. Then, the connecting block 3 and the second connecting sleeves 5 at both ends are rotated, and then the threaded connection relationship between the adjusting bolt 4 and the second connecting sleeve 5 is adjusted, so that the two second connecting sleeves 5 respectively drive the corresponding connecting crossbar 6 and the third connecting sleeve 7 to move accordingly until they are adjusted to the corresponding length.

[0052] Then, the third connecting sleeve 7 at one end is fixedly connected to the corresponding connecting bolt 8 on the first connecting sleeve 2 by threaded connection, and then the third connecting sleeve 7 at the other end is fixedly connected to the connecting bolt 8 on the other first connecting sleeve 2, so that the fixed connection of the overall structure of the adjustable cross bar assembly and the vertical bar assembly can be achieved.
