Problems solved by technology
The traditional box girder internal formwork construction mainly adopts the overall assembly of wooden formwork segments and the loose assembly of combined steel formwork. These two internal formwork construction methods cannot meet the current box girder construction progress under the background of the rapid increase in the amount of box girder construction. and construction cost, it is necessary to formulate a set of internal formwork construction methods to guide the construction of box girder internal formwork and improve the efficiency of box girder construction

Embodiment Construction
[0018] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0019] A special-shaped retractable T-shaped box girder inner formwork 2 support system, the inner formwork 2 support system includes T-shaped box girder 1, inner formwork 2, horizontal support 33, vertical support 44, support adjustment screw 5, support beam 6, nodes Connecting pin 77, supporting connection node 8, the support system of the inner formwork 2 is a ring structure, and the inner formwork 2 is connected by hinges. The inner formwork 2 includes a horizontal support 3 and a vertical support 4 located in the middle of its four sides. The two ends of the horizontal support 3 are supported at the node connection pin 7 of the inner formwork 2, and the horizontal support 3 is connected by a support adjustment screw, and the length of the diagonal is adjusted through thread rotation to control the tightness of the inner formwork 2. The side inner formwork 2...

The invention provides a retractable and expandable box girder inner formwork supporting system, which is made of an aluminum alloy formwork, wherein the inner formwork is of an annular structure, thesupporting force is enhanced through the annular structure, the aluminum alloy formwork is good in stability and high in bearing capacity at the same time, and the overall rigidity can be greatly improved. The invention further provides a supporting method of the supporting system, which comprises the steps of fixing the bottom of the box girder formwork to a foundation, rotating lead screws, slowly opening the formwork, fixing the lead screws, and checking the formwork; and pouring concrete, rotating the lead screws to enable a supporting mechanism to contract, and finally removing the formwork. The annular inner formwork is arranged to be retractable, the formwork is opened and tightened to form an annular structure when being supported, the formwork is folded through the screws duringformwork removal, the annular structure is loosened, the formwork has a centripetal pull force when being loosened, the removal is facilitated, the formwork is still a whole after formwork removal, and the circulation is facilitated.
Description
technical field [0001] The invention belongs to the field of bridge construction, and relates to a special-shaped telescopic T-shaped box girder inner template support system and a support method thereof. Background technique [0002] With the rapid development of bridge construction, the construction technology of box girder is basically mature and has entered the standardized construction technology. The traditional box girder internal formwork construction mainly adopts the overall assembly of wooden formwork segments and the loose assembly of combined steel formwork. These two internal formwork construction methods cannot meet the current box girder construction progress under the background of the rapid increase in the number of box girder construction projects. In order to meet the needs of construction cost and construction cost, it is necessary to formulate a set of internal formwork construction methods to guide the construction of box girder internal formwork and i...
