Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] like figure 1 Shown, the connection method of the supporting system of the present invention and the top ring beam, its specific steps are:
[0016] 1) Treat the foundation under the top plate 1
[0017] Before the construction of the top ring beam 4 and the "corbel" 10, the line is measured and set out according to the plan layout of the support "corbel" 10, and the counter-pressure pile 8 is constructed under the top slab 1 to increase the bearing capacity of the foundation under the top slab 1 , to prevent the torsional shear failure of the top ring beam 4.
[0018] 2) The connection between the top ring beam 4 and the support "corbel" 10
[0019] According to the layout plan of the supporting "corbel" 10, find out the position where the supporting "corbel" 10 is set in the crimping ring beam 4, carry out the measurement and setting out, an...

The invention relates to a connection method for an elevated steel support system and a top ring beam. The connection method for the elevated steel support system and the top ring beam is used for solving the connection problem of the elevated steel support system and the top ring beam. The connection method for the elevated steel support system and the top ring beam comprises processing foundation under pressure top plates; arranging a supporting bracket at connecting position of the top ring beam and the steel support system; enabling main reinforcement of the supporting bracket to be anchored into the top ring beam to enable the supporting bracket and the top ring beam to be combined into a whole; then connecting the elevated steel system with the supporting bracket to enable steel support bore axial force to be transmitted onto the supporting bracket and the top ring beam. The connection method for the elevated steel support system and the top ring beam has the advantages of solving connection between the steel supporting system and the top ring beam, avoiding pier bearing platform integrity damage caused by pouring on the pier bearing platform for a plurality of times through construction units, enabling the pier bearing platform to reflect good structural behavior during later utilization, shortening construction periods and bringing certain economic benefits due to the fact that the steel supporting system and the top ring beam are connected to form into a whole.
Description
technical field [0001] The invention relates to a method for connecting the steel support system and the top ring girder in the enclosure of the main pier cap of a bridge, in particular to a raised support when the elevation of the natural floor on site is lower than the surface elevation of the pier cap. The method of connection of the system to the top ring beam. Background technique [0002] At present, in the design of the foundation pit enclosure of the pier cap, the natural floor elevation on site is lower than the surface elevation of the pier cap, and both the construction unit and the design unit of the bridge hope to pour the pier cap at one time, because many The secondary pouring will cause certain defects in the mechanical performance of the pier cap, and will also prolong the construction period. Therefore, there is a need for a method of connecting an elevated support system to a capping ring beam. Contents of the invention [0003] The present invention a...
