Embodiment Construction
[0036] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0037] This embodiment provides an erection method of an intelligently monitored lower string reinforcement system, which is erected and installed synchronously with the bridge, such as figure 1 As shown, the bottom chord reinforcement system includes a screw-in connector, a chain rod I5, a chain rod II8, and a strut 9 connected by pin shafts in a specific order. The lower chord reinforcement system is symmetrical along the longitudinal central axis, and is illustrated by one side. The transition units 18 at both longitudinal ends of the bridge are respectively installed with screw-in connectors. The above chain rods Ⅱ8 are coaxially connected together, and two or more chain rods Ⅱ8 are parallel to the bridge after being docked; in the vertical direction, a strut 9 is set at the hinge of the chain rod Ⅰ5 and the chain rod Ⅱ8, and the two horizontal struts ...

The invention discloses an erection mechanism and method for an intelligently monitored lower chord reinforcement system. The erection mechanism comprises tensioning mechanisms, working platforms, anintelligent monitoring system and chain bar lifting rings. The chain bar lifting rings are in one-to-one correspondence with chain bars of the lower chord reinforcement system, one ends of the chain bar lifting rings are connected with a bridge, the other ends of the chain bar lifting rings are connected with the corresponding chain bars, and the chain bars are suspended at the lower end of the bridge by the chain bar lifting rings. The tensioning mechanisms are in one-to-one correspondence with struts, and the tops of the struts are connected to the lower part of the bridge through the corresponding tensioning mechanisms. The tops of the struts can be moved in the longitudinal direction of the bridge through the tensioning mechanisms, and the positions of connecting points between the tops of the struts and the bridge are adjusted to tension the lower chord reinforcement system; the working platforms are installed on the outer sides of the tensioning mechanisms, and are used for providing working space for staff to operate the tensioning mechanisms; and the intelligent monitoring system is used for monitoring pressure in a lower chord reinforcement assembly, and a warning is givenwhen the monitored pressure exceeds an internally preset pressure threshold. The erection mechanism can be assembled manually and erected and installed synchronously with the bridge, and has high efficiency.
Description
technical field [0001] The invention relates to the technical field of road transportation, in particular to an erection mechanism and an erection method of an intelligently monitored lower string reinforcement system. Background technique [0002] The existing large-span emergency bridges in my country have shortcomings such as self-heaviness and long assembly and erection time. In order to further meet the increasingly stringent requirements of emergency support tasks, a chord system is used to externally reinforce the main body of the bridge under the bridge, which can reduce the weight of the main body of the bridge. Increase the bearing capacity of the bridge. [0003] Generally, the erection and installation of the chord system requires special equipment such as trailers, cranes or trucks, which takes up a lot of space, and it is inefficient to erect the chord system independently after the bridge erection is completed. Contents of the invention [0004] In view of t...
