Specifically, the positioning mechanism may include a positioning table 11 and a positioning hole 12, and the positioning table 11 and the positioning hole 12 are respectively located at two ends of the supporting rod 1. Wherein, the structure shapes of the positioning table 11 and the positioning hole 12 are the same, therefore, the positioning table 11 on one strut 1 can be inserted into the positioning hole 12 on the other strut 1. The positioning table 11 and the positioning hole 12 are connected, so that the adjacent struts 1 can be connected quickly. It should be noted that, in an embodiment, the positioning table 11 and the positioning hole 12 are cylindrical structures, but are not limited thereto, and the specific structures of the positioning table 11 and the positioning hole 12 may be determined according to actual requirements, for example, the positioning table 11 and the positioning hole 12 may also be triangular prism, quadrangular prism, or polygonal prism structures. When the positioning table 11 is of a polygonal prism structure, the two support rods 1 connected with each other can be prevented from rotating through the polygonal prism structure, and therefore the actual connection effect between the two support rods 1 can be improved.
Referring to fig. 3 and 4, in one embodiment, the connecting structure 3 is located on the supporting rod 1, and includes a support 41, a fixing sleeve 42, a connecting head 32, and a plurality of connecting seats 31. The support 41 is an annular structure, so that the support 41 can be sleeved on the support rod 1, and the support 41 and the support rod 1 are fixedly connected by welding. However, the specific manner of the fixed connection between the support 41 and the strut 1 may be determined according to actual requirements. Wherein, the inner diameter of the support 41 is further provided with a limit groove 43, the limit groove 43 is of an annular structure, and the limit groove 43 can be allowed to be coaxially arranged with the support rod 1. Therefore, the connecting seat 31 may be allowed to be located in the stopper groove 43 so that the connecting seat 31 is connected with the strut 1.

Therefore, the cross bar 2 is connected with the through hole 320, so that the cross bar 2 and the rod 1 are in a relatively fixed state.
It should be noted that, threaded holes are allowed to be opened on the support rod 1 and the connector 32, and bolts are connected in the threaded holes. Specifically, on the supporting rod 1, the threaded hole is communicated with the positioning hole 12, so that the positioning table 11 positioned in the positioning hole 12 can be locked by the bolt through the threaded hole, so as to improve the connection strength between the adjacent supporting rods 1. And, on the connector 32, the threaded hole is communicated with the through hole 320 on the connector 32, so that the bolt can lock the cross rod 2 in the through hole 320 through the threaded hole, thereby improving the connection strength between the cross rod 2 and the connector 32.
Referring to fig. 1-5, in one embodiment, the fixing sheath 42 is a ring structure, and the fixing sheath 42 is disposed on the supporting rod 1. Wherein, the fixing sleeve 42 is slidably connected with the support rod 1, and the fixing sleeve 42 is located at the other side of the connecting seat 31. Specifically, the fixing sleeve 42 may be provided with a limiting groove 43 similar to that of the support 41, and the other end of the connecting seat 31 may be located in the limiting groove 43 of the fixing seat. Therefore, by connecting one end of the connecting seat 31 with the holder 41 and the other end of the connecting seat 31 with the fixing sleeve 42, relative fixation between the connecting seat 31 and the strut 1 is achieved. Meanwhile, the fixing sleeve 42 is slidably connected to the strut 1, so that the connecting seat 31 can be easily and rapidly removed from the strut 1. It should be noted that the fixing sleeve 42 may be provided with an internal thread, and the internal thread is a limiting groove 43 on the fixing sleeve 42. It is permissible to provide external threads on the connecting socket 31 and at the connecting end of the connecting socket 31 and the fixing sleeve 42. Therefore, the fixing sleeve 42 and the connecting seat 31 can be allowed to be connected to each other through the external thread and the internal thread to improve the practical strength of the connecting structure 3 and to improve the safety of the construction bracket for construction work.
Specifically, in the actual use process of the construction support for engineering construction, the corresponding connecting seats 31 can be selected according to the installation number and the orientation requirement of the cross bars 2. Secondly, one end of each of the plurality of connecting seats 31 is sequentially inserted into the limiting groove 43 of the support 41, and the adjacent connecting seats 31 are matched with each other through the groove 33 and the boss 34 until all the connecting seats 31 are installed to form a cylinder to wrap the support rod 1. Then, the fixing sleeve 42 is sleeved on the support rod 1, the fixing sleeve 42 is screwed on the connecting seats 31 through threads, and the other ends of the connecting sleeves are fixedly connected through the fixing sleeve 42. And finally, inserting one end of the cross rod 2 into the connector 32 and then locking the cross rod through a bolt to form the construction support for engineering construction.
It should be noted that, when the stand is coupled and matched with another stand, the cross bar 2 is inserted into the through hole 320 of the connector 32 of the other stand and locked by the bolt for the stand located in the front, rear, left and right directions. For the supports positioned at the upper and lower positions, the positioning platforms 11 on the adjacent supporting rods 1 are matched with the positioning holes 12 and locked through bolts.
In summary, the invention discloses a connection structure and a construction support for engineering construction, which can effectively solve the problem that the existing construction support for engineering construction is not easy to connect in the using process. Wherein, the two ends of the connecting seat 31 are respectively connected with the support 41 and the fixing sleeve 42, so that the connecting seat 31 and the supporting rod 1 are relatively fixed, and the connecting seat 31 can be quickly detached from the supporting rod 1. The fixing sleeve 42 and the connecting seat 31 are connected with each other through threads, so that the actual strength of the connecting structure 3 can be improved, and the safety of the construction support for engineering construction is improved. Therefore, the invention effectively overcomes some practical problems in the prior art, thereby having high utilization value and use significance.
