The bar 600 is maintained at the current height, and the dowel 800 is pulled out of the previous second opening 610 and inserted into the next second opening 610 to continuously raise the bar 600 for continuous fine adjustment.

The previously described means of maintaining the post 600 at the current height may be manually held or temporarily secured using other means, such as inserting a dowel 800 into a second opening 610 in the protruding section of the post 600 closest to the sleeve 500 to prevent the post 600 from slipping excessively. Or, the stop collar 700 sets up to open and shut fastener formula structure, and the dowel 800 sets up to two, rotates stop collar 700 and drives first dowel 800 and move to next second trompil 610 along first trompil 511 and appear when the scope at first trompil 511, inserts second dowel 800 into next second trompil 610, takes out first dowel 800, takes off the lock with stop collar 700 and moves on in order to drive second dowel 800 in the below of second dowel 800, so reciprocal in order to finely tune in succession.

The structure of the rib 800 is shown in fig. 11, and the rib 800 has a ring shape with an opening for allowing the sleeve 500 to pass right through, i.e., the opening is in interference fit with the sleeve 500. The dowel 800 comprises an insertion end 810 and a retaining end 820, the insertion end 810 is inserted into the first opening 511 and the second opening 610 along the radial direction of the sleeve 500 and the support rod 600, the retaining end 820 is wound on the periphery of the sleeve 500, and the opening is positioned between the insertion end 810 and the retaining end 820.

When the insertion rib 800 is inserted, the sleeve 500 interferes with the insertion end 810 and the anti-slip end 820, the sleeve 500 is clamped into the opening by using the elasticity of the insertion rib 800, the insertion end 810 is inserted from the first opening 511, and the anti-slip end 820 is wound around the outer circumference of the sleeve 500 to prevent the insertion end 810 from being accidentally pulled out.

The stop collar 700 is provided with the ear in order to conveniently twist, and the ear of stop collar 700 is equipped with the through-hole, and the stop collar 700 be equipped with the through-hole complex actuating lever 900 of ear, as fig. 12, actuating lever 900 is the L type, and the through-hole of ear is inserted to the one end of actuating lever 900, pulls the other end of actuating lever 900 so that the stop collar 700 rotates along circumference.

In the support bar provided by the embodiment of the present application, the length of the main rod 20 is adjustable, the main rod 600 is moved to approximately adjust the length, then the limit ring 700 is rotated to move up or down to finely adjust the length of the support bar 600, so that the height of the support head 10 is equal to the height of the horizontal form 30, the connecting seat 200 is approximately flush with the horizontal form 30, so that the connecting seat 200 is connected with the horizontal form 30, and then the adjusting nut 400 is rotated to drive the bearing plate 320 to ascend to abut against the keel 40 of the horizontal form 30, so that the support bar can complete one support, and the horizontal form 30 can be stably supported by arranging a plurality of support bars, as shown in fig..

The application provides a bracing piece need not to add and is used for supporting tight wedging piece, need not to add horizontal pole, the down tube that is used for the drawknot, and the bracing piece is good with horizontal template 30 wholeness, easy operation, and the installation is dismantled conveniently.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
