Preferably, the first member is a prefabricated wall body, and the second member is a prefabricated beam.

Preferably, the L-shaped connecting piece is made of angle steel.

Preferably, the first connecting sleeve and the second connecting sleeve are both M12 sleeves.

Preferably, the keyway has a length, width, and depth of 200mm, 100mm, and 120mm, and the keyway has an open opening at an end adjacent the second member.

Preferably, the thickness of the L-shaped connecting piece is 7 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses can be in the same place its very first time fixed connection after first component of hoist and mount and second component are accomplished, relative prior art, it is first to have saved pre-buried, the connecting sleeve and the a detachable word connecting piece on two component surfaces, and when realizing first with L type connecting piece, two component fixed connection, saved first, the connecting reinforcement between the two components, can directly fill up the keyway with the mortar after L type connecting piece connection is accomplished, do not need the later stage to carry out L type connecting piece and first, two connecting sleeve's dismantlement.

2. Connect with the connecting reinforcement relatively, the utility model discloses a fixed back of L type connecting piece, it is inseparabler to connect between first, the two components, and the possibility that the component removed when having reduced concreting.
