Embodiment
To make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality
It is described in detail with longitudinal connecting structure between a kind of high intensity Zone beam slab of new offer.
Longitudinal connecting structure between a kind of high intensity Zone beam slab, including the end with reserved anchor hole 12 and anchor plate 11
Crossbeam 1, the movable rod 3 with piston 7 and the internal cavity 4 for being filled with fluid media (medium) 5.It is appropriate in box beam or T beam-ends crossbeam 1
Anchor hole 12, the fixing end as movable rod 3 and cavity 4 are reserved by design requirement in position；Piston 7 separates cavity 4 to be formed
Two cavitys communicated, movable rod 3 do relative motion inside cavity 4, and the inside of cavity 4 is filled with fluid media (medium) 5.This practicality
Relative motion between the new beam slab that can realize mutual displacement under speed operation, and in the case of high speed or big displacement
Spacing, antidetonation effect.12 a diameter of 20 ± 0.5mm of anchor hole, reserved when beam slab is prefabricated or cast-in-place according to design drawing；
2 a diameter of 18 ± 0.5mm of anchor bolt, anchor bolt 2 passes through anchor hole 12 after the completion of beam slab erection, passes through anchor plate
11 are fixed on movable rod 3 and cavity 4 on end floor beam 1；The movable rod 3 does reciprocal low-speed motion in cavity 4；It is described
Cavity 4 is hollow circular cylindrical cavity, and movable rod 3 passes through from the both ends of cavity 4, and inside is filled with fluid media (medium) 5；The fluid
Medium 5 has reverse thixotropic behavior, and its viscosity is the increasing function of velocity gradient.A solid is similar to when being acted on without external load,
But can slowly it be flowed under constant pressure at a slow speed；Becoming solid again at a high speed, under larger displacement impact suddenly；This practicality is new
Longitudinal connecting structure between high intensity Zone beam slab described in type, the piston 7 are fixed on movable rod 3, and diameter is slightly less than
The internal diameter of cavity 4, cavity 4 is separated to form two cavitys communicated.The tip inside of cavity 4 includes seal 6, including seal
(6) the other end is provided with end-blocking 8, and movable rod 3, which is located on the part outside the cavity 4, is additionally provided with dust cover 9.
After beam body erection installs, the utility model constructing apparatus is installed, under normal circumstances, due to shrinkage and creep and just
Normal micro-displacement (expanding with heat and contract with cold under such as ambient temperature effect, and often wind, the lower extremely slow phase of generation of small vibration effect
To sliding), the fluid media (medium) 5 in cavity 4 remains fluid properties, is flowed to by the cavity wall gap of cavity 4 from the one end of piston 7 another
One end, piston 7 can move freely in cavity 4, and fluid media (medium) 5 will not produce harmful restraining force, without limitation between beam slab
Free movement.When beam slab suddenly by exterior vibration load when, quick movement occurs for beam slab band piston 7 and cavity 4, and fluid is situated between
Matter 5 to flow in cavity wall gap at high speed very much, and viscosity increases sharply, and last fluid media (medium) 5 almost becomes solid, piston 7
It is locked, it can not move.The position limitation protection effect to beam slab is played, prevents the collision between beam slab, while external force can also be passed
It is delivered on other structures part, mitigates the load burden of certain structural member, serves distractive load defencive function.After external force disappears,
Pressure of the fluid media (medium) 5 in the both sides of cavity 4 gradually balances, and makes that internal stress accumulation will not be produced in cavity 4.
It is understood that embodiment of above is merely to illustrate that principle of the present utility model and used exemplary
Embodiment, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, and these variations and modifications are also considered as this reality
With new protection domain.
