Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a be brace rod 1 that the V-arrangement was arranged, one of them side of brace rod 1 is connected with first horizontal muscle 2, and another side is connected with the horizontal muscle 3 of second, and the setting is stretched to the horizontal muscle 3 of second in first horizontal muscle 2 orientation, and the setting is stretched to the horizontal muscle 2 of second in the horizontal muscle 3 orientation, and first horizontal muscle 2 is connected with the horizontal muscle 3 of second, and is provided with at connecting portion between them and connects length adjustment structure. The utility model provides a brace rod 1, first horizontal muscle 2 and the horizontal muscle 3 of second all can adopt the on-the-spot reinforcing bar to make.

The connection length adjustment structure of the first transverse rib 2 and the second transverse rib 3 may have various implementation manners, for example, one has a rotary joint with a threaded sleeve, the other side adopts a threaded rod, and the adjustment of the connection length can be realized through the threaded connection structure. This approach is convenient to operate, but is correspondingly costly. For the on-the-spot preparation of being convenient for, practice thrift the cost, the utility model provides a more simple and convenient mode is with the horizontal muscle 3 looks overlap joints of first horizontal muscle 2 and second to it is fixed at overlap joint portion ligature between them.
