The utility model discloses a push trolley device for installation and removal of a steel side template, which can move forwards, backwards, leftwards and rightwards. The two sides of the push trolleyare respectively provided with a trolley skeleton which consists of four vertical beams, the vertical beams arranged on the inner side of the skeleton are respectively connected with two cross beams,the two ends of the skeleton are connected with a transverse coupling, horizontal movement rollers and vertical movement rollers for a template are connected between the inner vertical beams and theouter vertical beams on the two sides, template lifting jacks are connected between the inner vertical beams on the two sides and are also connected with a jack lifting platform, and the two ends of the horizontal movement rollers are connected with the inner vertical beams and the outer vertical beams through support plates. The utility model has the advantages of simple structure, convenient operation, cost-saving performance and the like. In the traditional construction of the in-situ cast beam, the removal and installation of the side template requires the 50-ton crane, the 30-ton platformtruck and also six days. At present, only four people and two days are required for the removal, movement and installation of the side template of the box beam. Therefore, the utility model improvesthe efficiency by more than three times, saves the cost by about ten times, and can be widely sued in the construction of the beam prepared with the scaffold.
