Embodiment Construction

[0018] In order to adapt to the application of hanging basket hanging construction in the main girder of wider bridge deck, the present invention provides a hanging basket hanging construction system. The invention will be described in detail below with reference to the accompanying drawings.

[0019] Such as figure 1 , figure 2 As shown, the hanging basket suspension construction system provided by the present invention includes a hanging basket device and a running device.

[0020] The hanging basket device includes four groups of main trusses 11, 12, 13, 14 arranged above the concrete main beam 100 and eight groups of bottom mold support devices 10 arranged below the concrete main beam, each group of main trusses 11, 12, 13, 14 Arranged along the direction of the transverse bridge respectively, each set of main trusses corresponds to two sets of bottom mold support devices 10, and the front and middle parts of the bottom mold support devices 10 are respectively provided w...

Abstract

The invention discloses a system and a method for cradle cantilever construction. The system comprises a cradle device and a travelling device, the cradle device comprises a plurality of primary trusses and a plurality of bottom die supporting devices, each bottom die supporting device comprises a sliding beam and a transverse beam, the travelling device comprises a primary truss travelling device and a bottom die supporting device travelling device, the primary truss travelling device comprises a plurality of sliding ways and primary truss pushing jacks in one-to-one correspondence to the primary trusses, the bottom die supporting device travelling device comprises hoists and bottom die longitudinally-moving jacks, the hoists are fixed onto the corresponding primary trusses and are connected with front hangers through steel wire ropes, an anchor beam is fixed to the front end of a concrete girder or a cross wall, a longitudinally travelling reaction seat is arranged at the top of the rear end of each sliding beam, and the bottom die longitudinally-moving jacks are fixed onto the anchor beam and connected with the longitudinally travelling reaction seats through stretch-draw traction steel strands. By the aid of the primary trusses and the corresponding bottom die supporting devices, cradle cantilever construction of a wide bridge deck and girder structure can be realized.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a construction system and method for suspension casting of hanging baskets. Background technique [0002] Hanging basket cantilever construction has become the main construction method of modern long-span bridge construction. It does not need to erect channel steel brackets, does not use large cranes, and has the advantages of light structure, simple and convenient assembly, and no pressure. [0003] The traditional hanging basket cantilevered main girder construction generally adopts two main truss structures, and the cooperative construction between the main trusses is relatively simple, but for the main beam with a large bridge deck width, the traditional hanging basket cantilevered main beam construction technology exists. Some problems make it difficult to guarantee the construction quality. Contents of the invention [0004] The technical problem to be solved by the pr...
