Further, the base comprises a first subsection and a second subsection which are fixedly connected with the first hoop and the second hoop respectively, and sawteeth which are matched with each other are arranged between the first subsection and the second subsection. The base comprises a first subsection and a second subsection, the first subsection and the second subsection are fixedly connected with the first hoop and the second hoop respectively, the other ends of the first subsection and the second subsection are free, and when the first hoop and the second hoop are locked, the first subsection and the second subsection are driven to be close to each other and combined to form the base. The sawteeth which are matched with each other are arranged between the first part and the second part, so that the friction between the first part and the second part is increased, the first part and the second part are prevented from being easily damaged after being stressed, and the stability is improved. The first hoop and the first subsection are integrally formed, the manufacturing process is convenient, and the structural stability is good.

Further, be equipped with the confession on the assembly ear one the bolt hole that fastening bolt passed, be equipped with on the assembly ear two with the outside U-shaped fluting that link up of fastening bolt complex, fastening bolt pass the bolt hole on the assembly ear one and the U-shaped fluting on the assembly ear two, adopt the nut locking, set up the outside U-shaped fluting that link up on the assembly ear two, when opening or locking connection spare, can keep clamp one motionless, after screwing the nut, rotate clamp two and just can realize convenient operation, labour saving and time saving.

To sum up, the utility model discloses a bottom at the connecting piece sets up the collet, increases the ability of weighing of scaffold frame bottom, prevents its atress lapse or displacement, improves scaffold frame connection's stability and constructor's security.

Detailed Description

An embodiment of a connecting member for a scaffold bottom according to the present invention will be further described with reference to fig. 1 to 5.

The utility model provides a connecting piece suitable for scaffold frame bottom, includes two semicircular clamps one 2 and two 9 of clamps, the one end of one 2 of clamps and two 9 of clamps is articulated, and the other end is equipped with the assembly ear one 4 and the assembly ear two 7 of mutually supporting respectively, be equipped with fastening bolt 6 between assembly ear one 4 and the assembly ear two 7, be equipped with base 3 between the bottom of one 2 of clamps and two 9 of clamps. One ends of the first hoop 2 and the second hoop 9 are hinged with each other through the rotating shaft 1, and a fastening bolt 6 is arranged between the first assembling lug 4 and the second assembling lug 7 at the other end. During the use, open clamp 2 and clamp two 9, place the montant 14 of scaffold frame in the circular through-hole that both formed, through fastening bolt 6 locking, the base 3 of bottom is tightly blocked between two clamps simultaneously, montant 14 is withheld by the base 3 of bottom, as long as receive great power when montant 14 and just can fall or remove base 3 destruction downwards, the security that can its stability of greatly increased and be under construction.
