The invention discloses a connecting piece capable of regulating horizontal folding direction of a beret truss. The connecting piece comprises side plates, a top plate and a bottom plate; two side plates are arranged; the two side plates are arranged in parallel relative to each other in the vertical direction; the top plate and the bottom plate are arranged in parallel relative to each other in the vertical direction; the top plate and the bottom plate are arranged on the right sides of the central axes of the side plates in the vertical direction; the top plate, the bottom plate and the twoside plates are enclosed to form a cavity; a male head of a beret piece is inserted into the cavity; a vertical plug pin hole is formed in the centre of each of the top plate and the bottom plate; thevertical plug pin holes are used for rotatably connecting the male head of the beret piece; and horizontal plug pin holes are used for detachably connecting a female head of the beret piece. The included angle between adjacent two beret pieces is regulated by rotating the male head of the beret piece in the cavity in the horizontal direction, so that the beret truss can be subjected to horizontalfolding effectively. The beret piece can facilitate the detachment of the beret truss, and can also perform horizontal folding on the beret truss effectively, so that the construction speed and the construction efficiency are greatly improved.
Description
Technical field [0001] The invention relates to the technical field of cast-in-place bridge construction, in particular, to a connecting piece, a connecting structure and a connecting method that can adjust the horizontal folding direction of a Bailey frame. Background technique [0002] At present, in highway construction, more and more cast-in-place box girder curve bridges need to cross existing roads, rivers, valleys and other topography, and the supports often adopt the method of steel pipe column Bailey frame support. But generally the berets are connected by a horizontal socket, which makes it impossible to bend horizontally, or use the top-bend female to make the beret frame slightly bend horizontally. Therefore, when arranging the Bailey frame under the curved bridge, the method of widening and lengthening the support foundation and increasing the number of supports is often used to increase the erection area, thus increasing the project cost. Summary of the invention ...
