Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, in the present embodiment, the foundation underpinning system of old brick foundation building, including coupling beam bed course 6,
Two shoulder pole girders, 1, two coupling beam 2 and two anchor jacked piles 4.
The building of old brick foundation 5 has original basis bed course 3.The foundation underpinning system of old brick foundation building is just arranged in
On original basis bed course 3.Coupling beam bed course 6 forms for concreting, is fixed on original basis bed course 3.It is opened on old brick foundation 5
Hole 51, for placing shoulder pole girder 1.
Shoulder pole girder 1 is horizontally set on 6 top of coupling beam bed course, runs through old brick foundation 5, and old brick foundation 5 is stretched out at both ends.Such as
Shown in Fig. 3, shoulder pole girder 1 includes shoulder pole girder steel reinforcement cage 11, channel steel 12 and shoulder pole girder concrete 13.The web of channel steel 12 is vertical,
Wing plate is horizontally set in shoulder pole girder steel reinforcement cage 13, can be fixed with spreader beam steel reinforcement cage 13 by the way of steel bar welding.Shoulder pole
Beam steel cage 11 runs through old brick foundation, and old brick foundation is stretched out at both ends.Shoulder pole girder concrete 13 is poured full of shoulder pole beam steel
The aperture 51 of cage 11, channel steel 12 and old brick foundation 5, the general 250~300mm in aperture can not be too big, prevents old brick base
Plinth 5 damages.Shoulder pole girder 1 is fixed on old brick foundation 5.The circumference of opening 51 is the outer circle of shoulder pole girder concrete 13,
It is the outer circle of shoulder pole girder 1.
