The simple box-type glass packing frame is suitable for packing plate glass as well as plate stone, liquid crystal glass and other plate material. The box-type glass packing frame consists of two packing stands of profiles, and each of the packing stands is one box structure with one side opening and including four uprights, cross pieces between uprights, end plates on the upper and lower ends of uprights, reinforcing plates welded outside the uprights, hanging hooks mounted to the reinforcing plates and soft buffering material inside the box. The uprights and the cross pieces are made of metal or engineering plastic profiles.

The invention discloses a high-density polyvinyl chloride drainage board and a preparation method thereof, and particularly relates to the technical field of waterproof materials. Thehigh-density polyvinyl chloride drainage board comprises a drainage board body, wherein a stud is arranged on one side of the drainage board body, an inserting groove is formed in one end of the drainage board body, and an inserting bar is arranged at the other endof the drainage board body; guiding grooves are formed in the inner walls of the two sides of the inserting groove, and guide bars are arranged onthe two sides of theinserting barcorrespondingly;an embedding groove is formed in the outer side of the top end surface of theinserting groove; and a sealing plate is arranged at the top end of the inserting groove in a matched mode. According to the high-density polyvinyl chloride drainage board andthe preparation method thereof, by using the matched type inserting groove and the inserting bar as well as the guide grooves and the guide bars, the connection convenience between the adjacent drainage board bodies can be greatly improved, the sealing plate is fixed in the inserting groove by a locking bolt, so that the connection between the two adjacent drainage board bodies is more stable, meanwhile, by adding flat glass fibers and glass flakes to a formula, the compressive strength of the drainage board can be greatly improved, and the water absorption rate can be reduced.
