[0007] Preferably, the storage rack has a plurality of uniformly distributed limiting grooves, the plurality of limiting grooves are in one-to-one sliding contact with the plurality of tightening ropes, and the plurality of limiting rings are in abutment with the storage rack.

[0008] Preferably, the top end of the storage rack has an arc-shaped groove in communication with the limiting groove.

[0009] Preferably, the prefabricated block has a plurality of heat insulation grooves, a support frame is arranged at each of the plurality of heat insulation grooves, and a plurality of heat insulation plates are arranged between the support frame and the prefabricated block.

[0010] Preferably, the support frame is made of concrete.

[0011] Preferably, the limiting ring and the tightening rope each have a limiting tooth, and the limiting ring and the tightening rope are in one-way clamping.

[0012] Compared with the prior art, the utility model has the beneficial technical effects that:

[0013] When the utility model is used, the user lays the reinforcing bars staggered on the fixing assembly of the prefabricated block, then pulls the tightening rope to move the tightening rope from the top end of the reinforcing bar to the storage rack, moves the limiting ring on the tightening rope, reduces the distance between the limiting ring and the limiting rod, so as to fix the reinforcing bar by cooperation of the tightening rope and the storage rack, and when the reinforcing bars in different planes are fixed on the storage rack, the user can pull out the storage rack by the tightening rope, so as to abut and fix the storage rack with the reinforcing bar, thereby improving the stability of the reinforcing bar binding.
