Description
Technical field
The present invention relates to T-type beam, in particular to a kind of joint strengthening type T-type beam reinforcement cages and its construction technology.
Background technique
T-type beam refers to that cross-sectional form is the beam of T-type, and the part of upper horizontal is the edge of a wing, vertically arranged among it
Part is beam rib.T-type beam is the equal of that will cut out in rectangular beam to the inoperative concrete in tension zone of bending strength, and original
The bending strength of rectangular beam is identical outer, can not only save concrete, but also mitigate the self weight of component, improve span ability.
Coast Expressway runs through the coastal north and south in Taizhou plain, will be the external traffic in the coastal industrial zone in Taizhou plain, object after building up
The backbone for flowing transport integrates coastal port resource to Taizhou regional traffic condition is improved, and promotes port competitiveness, promotes platform
The coastal industrial zone exploitation in state, promotes sustainable fast development of Taizhou economic society etc. to be of great significance, and wherein, Taizhou Wan is big
Bridge and wiring engineering are the important component of Coast Expressway (Zhejiang, Taiwan and Wenzhou highway multiple line) again, it is to arise from Sanmen County
Six Ao Zhen connect with Sanmen Wan bridge and wiring engineering, and Wenling city south of a city town connects Leqing Bay bridge and wiring engineering, route finally
Overall length 102.381km mainly has three through counties and cities along the line, borders on the sea, Jiangjiang, road and bridge and Wenling.
Above-mentioned bridge is in construction, in order to during building bridge over long distances, need largely to use T-type beam, in order to
It reduces project amount and improves environment protecting, the T-type beam in the engineering is all made of prefabricated mode and is made.When prefabricated, constructor
Member binds edge of a wing framework of steel reinforcement and beam rib framework of steel reinforcement in T-type beam mould, after the completion of binding, towards in T-type beam mould
Topple over concrete, the production of T-type beam is realized with this.
But this T-type beam, using in the course of work, when edge of a wing stress, beam rib forms support, the reaction of beam rib
Power can be applied at the connecting node of the edge of a wing and beam rib, and lack support at the connecting node of the edge of a wing and beam rib, and have can for pole at this
The edge of a wing can be caused to be deformed or be broken, influence the safety in later period.
Summary of the invention
The object of the present invention is to provide a kind of joint strengthening type T-type beam reinforcement cages and its construction technologies, have the enhancing wing
The advantages of bonding strength between edge and beam rib at connecting node.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of joint strengthening type T-type beam reinforcement cages, including beam rib framework of steel reinforcement and edge of a wing framework of steel reinforcement, the edge of a wing are used
Framework of steel reinforcement horizontally connects in the top of beam rib framework of steel reinforcement, and the two is in T-shape, and the beam rib framework of steel reinforcement is opposite
Two outsides are connected separately with bottom bracket, and the bottom bracket is located at the lower section of edge of a wing framework of steel reinforcement, and the bottom bracket includes vertical
The connecting plate of setting and loading plate perpendicular to connecting plate, the loading plate are fixedly connected on the top of connecting plate, the connection
