Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a prefabricated T-beam template with adjustable transverse slope. Background Art

[0002] In the construction of highway bridges, most bridges are erected with prefabricated beams to speed up the construction progress. Since the cross slope of the bridge deck changes in the designed flat curve section, the cross slope of the top plate of the concrete prefabricated beam also changes accordingly (the inclination angle needs to be changed). For this reason, in actual construction, the following two methods can usually be used to meet the construction requirements on the curve and different cross slopes. One is to make various prefabricated templates with different wing cross slopes and curvatures according to various bridge deck cross slopes and curve radii, but this method is difficult to implement and the cost is very high; the second is to thicken the bridge deck during the construction process, but this increases the design load of the bridge, which is not good for the quality of the bridge. Therefore, both methods not only consume a lot of manpower and material resources, but also lead to slow construction progress. Utility Model Content
