Description

A kind of Y type pier Construction of continuous beam π type bracket
Technical field
The utility model relates to bridge construction technical fields, more particularly to a kind of Y type pier Construction of continuous beam π type branch Frame.
Background technique
Y type pier is widely used in municipal administration/bridges in highway engineering, as shown in Figure 1, Y type pier includes cushion cap y1, vertical pier stud Y2, two oblique limb y3 and continuous beam y4, the cushion cap y1 play carrying, and the vertical pier stud y2 is mounted on cushion cap y1, described The bottom of two oblique limb y3 is connect with vertical pier stud y2 respectively, and top is respectively to extending on the outside of vertical pier stud y2 two, the vertical pier The oblique limb y3 of column y2 and two constitutes y-type structure, and the continuous beam y4 often uses box beam across on two oblique limb y3.
The construction characteristic of Y type pier pier consolidation continuous beam can be summarized as " new, high, difficult " three words, newly refer to that design is new Grain husk, technical requirements are tight, and construction is also required to innovate;Height refers to construction risk height, and appearance requirement is high, with high content of technology;Difficulty is Refer to that support system design is difficult.
Currently, domestic Y type pier continuous beam 0# block construction mainly uses Support Method, by setting between the oblique limb of Y type pier two Beam bottom mould holder is set, achievees the purpose that subsequent support Y type pier continuous beam 0# block bed die system.Beam bottom mould holder is usually to utilize ten thousand Can rod piece set up assembled falsework on the cushion cap pier shaft two sides of Y type pier, then the top of falsework be laid with Bailey beam, distribution beam and take If being formed, after the completion of beam bottom mould holder, then 0# block bed die system is installed on it.But the working procedure of this method is multiple Miscellaneous, higher cost is unfavorable for saving the duration, and difficulty of construction just will increase when bridge width is larger.There are also a kind of construction methods It is, in the oblique limb upper end setting built-in fitting of Y type pier or preformed hole, then beam bottom board bracket, 0# block bed die to be installed, although this method work Phase is shorter, but the oblique limb stress of Y type pier is larger, and construction safety risk is higher.
Utility model content
Based on this, the purpose of the utility model is to provide a kind of Y type pier Construction of continuous beam π type brackets, are used to support Y Continuous beam 0# block bed die system between the oblique limb of the two of type pier, it is simple with structure, can integral hoisting, reduce difficulty of construction, mention High working security improves construction quality, saves the advantages that duration and cost.
The technical solution that the utility model is taken is as follows:
