Cement grooves in tapered modular augments

An orthopedic augment (100) can be used where the patient's bone at an implantation site is structurally compromised to aid in securing the orthopedic prothesis at the implantation site. The orthopedic augment has, on an internal surface (2) thereof, cement fixation features (3) that receive an orthopedic cement therein and aid in resisting separation of the orthopedic prosthesis from the orthopedic augment. In addition, the orthopedic augment may include mechanical fixation mechanisms to engage the orthopedic prosthesis. Thus arranged, the orthopedic augment provides greater flexibility, in that it can be used in the form of a cone (e.g., cemented fixation) or a sleeve (e.g., mechanical fixation).

Waterproof outer wall for construction engineering

The utility model relates to a waterproof outer wall for a construction project. The waterproof outer wall comprises an inner wall body, a thermal insulation layer and an outer wallboard, the heat preservation layer is formed by arranging a plurality of heat preservation units in a matrix mode, and 1 / 4 circular inserting grooves are formed in the four corners of each heat preservation unit. The length and the width of each external wall panel are the same as those of each thermal insulation unit, and an anchoring pipe is fixed to the center of the diagonal line of the inner surface of each external wall panel and fixed in the corresponding inserting groove; air holes are formed in the outer surface of the outer wallboard and penetrate through the outer wallboard to be communicated with the anchoring pipe. The anchoring pipes on the external wall panel penetrate through the inserting grooves and are fixed to the internal wall body through cement, the firmness degree is far larger than that of glue bonding, and therefore the accident that the anchoring pipes and the heat preservation layer are peeled off together can be reduced. The external wall panel and the thermal insulation layer are installed in a staggered mode, the external wall panel covers the joint of the thermal insulation layer, and the downward-inclined joint is formed through the inclined face of the external wall panel, so that rainwater is difficult to enter or remain in the joint, and the waterproofness of the external wall is improved.
