Description

Bearing platform protector is used in municipal bridge construction Technical Field The utility model relates to the technical field of municipal bridge construction, in particular to a bearing platform protection device for municipal bridge construction. Background Municipal bridge cushion cap refers to the connection part of pier and pile foundation, plays a role in bearing and distributing the load transmitted by the pier body at the upper end, after the cast-in-situ completion of reinforced concrete pile columns in the circular embedded groove, the pile column reinforcement and the exposed reinforcement part are exposed outside after the concrete is coagulated, and if the pile column reinforcement and the exposed reinforcement part are exposed in rainy days or direct sunlight, the structure is corroded by rainwater or is sunk. The utility model discloses a Chinese patent, and an authorized bulletin number CN219621617U discloses a bearing platform protection device for municipal bridge construction, which comprises a foundation pit soil body, wherein a pile body is pre-buried in the middle of the foundation pit soil body, a reinforcing steel bar is fixedly arranged in the middle of the pile body, and a first bottom shield and a second bottom shield are respectively movably arranged at the top of the foundation pit soil body corresponding to the position of the pile body. Through remove the top to foundation ditch soil body with first bottom guard shield and second bottom guard shield to with the equipment of locating strip activity grafting at the inner wall completion first bottom guard shield of constant head tank and second bottom guard shield, later with the position correspondence of grafting piece and grafting groove, accomplish the equipment between first bottom guard shield and second bottom guard shield and the top guard shield, the device has successfully accomplished the installation this moment, can play better protective effect to stake body and reinforcing bar through first bottom guard shield of top guard shield cooperation and second bottom guard shield, thereby realized the purpose that improves the protective effect. The technical problem that has put forward in its background art has been solved to above-mentioned scheme, but in practical application, above-mentioned scheme still has certain defect, for example, the cushion cap height in the bridge construction is not fixed, but carries out nimble adjustment according to specific design requirement and construction condition, and the protector height among the prior art is certain, and the protector of fixed height can't match different cushion cap heights to lead to the practicality relatively poor. Disclosure of utility model The utility model aims to provide a bearing platform protection device for municipal bridge construction, which aims to solve the problems in the background technology. The bearing platform protection device for municipal bridge construction comprises a protection device, wherein the protection device comprises a top protection plate, a middle protection plate and a bottom protection plate, the top protection plate comprises a top cover, an extension plate is arranged at the bottom of the top cover, an elastic protection piece is connected to the bottom of the extension plate, the elastic protection piece is fixed with the middle protection plate, an adjusting piece is arranged between the extension plate and the middle protection plate, and the elastic protection piece is a waveform rubber elastic plate with the stretching rate of more than 150%, so that the protection device has good impact resistance and deformation recovery capacity, and the height of the elastic protection piece is adjusted through the adjusting piece.
