Description
Technical Field
The utility model belongs to the technical field of the shield tunnel technique and specifically relates to a shield tunnel walks guidance tape support convenient to ann tears open is related to.
Background
The tunnel inner walkway plate is a necessary temporary facility for tunnel construction, and the common installation form is that a walkway plate support is fixed on a pipe piece through a pipe piece bolt through a lifting lug on the support, so that the use requirement is met. The current guidance tape support is a whole, the welding links to each other between support and the lug, the lug angle is unanimous with the bolt hole angle, thereby guarantee that the bolt closely fixes the support to the tunnel segment, single can not accomplish the support during installation and fix, in the support transportation, save, the easy skew or deformation of taking place of lug angle in use and the installation, lead to the bolt can not closely laminate with the lug, the bolt can not be screwed up on the segment and guarantee that the segment closely laminates, thereby probably make the shaping tunnel produce the infiltration, the scene of wrong platform.
The current guidance tape support is a whole with the lug, needs two workman cooperation operations when walking guidance tape support mounting, and alone fixed bolster, alone adjusting position and bolt tightening, lug angle and bolt hole angle are unanimous to guarantee that the bolt closely fixes the support to the section of jurisdiction on, in the same way, also need two workman cooperations to demolish when walking guidance tape support demolishs. The lifting lug angle is easy to deviate or deform in the process of bracket transportation, storage, use and installation, so that the bolt cannot be tightly attached to the lifting lug, the bolt cannot be screwed on the duct piece to ensure that the duct piece is tightly attached, and the fixing reliability is poor.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a shield tunnel walks guidance tape support convenient to ann tears open to reach the installation and dismantle portably, lug non-deformable's purpose.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts does:
this shield tunnel walks guidance tape support convenient to ann tears open, including support body and lug, the support body includes continuous walking guidance tape support pole setting, walks guidance tape support arc pole and walks guidance tape support horizontal pole, walk and link to each other through bolt structure between the top outside of guidance tape support arc pole and the lug, be equipped with on the lug and be used for fixing the bolt hole on the tunnel segment of a jurisdiction.
Further:
the top outside of guidance tape support arc pole is equipped with the bolt, and one of lug is served and is used for the bolt hole with bolt complex.
The bottom of the arc-shaped rod of the walkway plate bracket is provided with a flat foot.
And the arc-shaped rod of the walkway plate bracket is attached to the inner wall of the tunnel pipe sheet.
The lug is square plate structure, and the one end of square board is equipped with the sleeve, forms the bolt hole in the sleeve.
The axis of the bolt hole is perpendicular to the axis of the bolt hole.
Compared with the prior art, the utility model, have following advantage:
the shield tunnel walkway plate support convenient to mount and dismount is reasonable in structural design, the support body and the lifting lugs are manufactured separately, the support body and the lifting lugs are connected in a matched mode through the bolt structures, and one worker can finish mounting during mounting and dismounting, so that mounting and dismounting are simple and convenient, construction efficiency is improved, and cost is reduced; and the lifting lug is not easy to deform, the defect of difficult alignment in installation is avoided, and the fixing reliability is good.
