In the technical solution of the utility model, be equipped with mild steel damper at structural beams base fabric, mild steel damper is supported by the short wall of steel concrete, thereby simple in structure, and engineering quantity is less, cost is lower.When earthquake occurs, this system provides additional damping to dissipate or to absorb the energy in earthquake input structure by local distortion, reduces agent structure earthquake response, and damping effect is reliably effective.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is that short wall supports seismic reinforcing structure schematic diagram;
Fig. 2 is mild steel damper structural representation.
Detailed description of the invention
As shown in Figure 1, short wall supports seismic reinforcing structure, comprise structural beams 3, be equipped with mild steel damper 1 at structural beams base fabric, described mild steel damper 1 is installed on the short wall 2 of steel concrete, described mild steel damper bottom is provided with base plate 11, top is provided with top board 12, described top board both sides are vertically welded with side plate 13, the described steel concrete corresponding mild steel damper of short wall 2 installation site is provided with pre-embedded bolt 20, the base plate of described mild steel damper is connected by the short wall 2 of pre-embedded bolt and steel concrete, described side plate 13 is by fixing to wearing bolt and structural beams 3, hole in position, the corresponding mild steel damper side plate bolt hole of described structural beams, adopt bar planting formula anchorage style to carry out mild steel damper side plate to fix to wearing bolt.The cross section of the short wall of described steel concrete is rectangle, long 2m, wide 0.24m.
As shown in Figure 2, be serially connected in one group of U-shaped mild steel bar unit of connecting with two U-shaped mild steel bars 101 by the first bolt 104,2～8 groups of U-shaped mild steel bar unit of connecting are at one end in a row closely connected with base plate and top board by the second bolt 102; , form and be connected in parallel between two row's series connection U-shaped mild steel bar unit in the fixing several U-shaped mild steel bar of the series connection unit on the same group mutually of base plate and the top board other end with identical connected mode; Equidistantly arrange that along base plate and the vertical axis of symmetry of top board the inner panel 103 of base plate and top board and inner side is fixed into one by the 3rd bolt 105.
The mounting structure of mild steel damper comprises the jack that promotes mild steel damper for suspending in midair, the operation platform arranging in the both sides of structural beams, and the steel bridging piece of placing between the operation platform of both sides, on the upper strata floor of structural beams top, be fixed with the otic placode for hanging jack suspension hook with expansion bolt.
The principle of short wall support energy consumption damping reinforcement system is that thinking is reinforced in the damping of a kind of " soft middle band steel ".At the bottom of structural beams, suitable position is arranged mild steel damper, damper is installed with high-strength and is carried out damper side plate and fix wearing bolt employing bar planting formula anchorage style, utilize activity gate-type scaffold building operation platform, coordinate to install after mild steel damper puts in place in conjunction with jack and weld, and be connected with the short wall of steel concrete at damper base plate pre-embedded bolt, be convenient to damper and in earthquake, damage rear Replacement and Repair.The short wall of anti-buckling steel concrete support take full advantage of pea gravel concreten mixings grouting material fast hard, early strong, without the feature of contraction, good fluidity, accelerating construction progress.When earthquake occurs, this system provides additional damping to dissipate or to absorb the energy in earthquake input structure by local distortion, reduces agent structure earthquake response.When geological process, be embodied in: in the time of little shake, mild steel damper, in elastic stage, provides rigidity to structure, structural system has enough anti-lateral rigidities; In, when action of strong earthquake, along with the increase of structure lateral displacement, first mild steel damper and short wall support system enter nonelastic deformation state, produce larger resistance, the seismic energy of the input structure that dissipates in a large number rapidly attenuating structure earthquake response; The major part of extremely strong seismic energy is dissipated by damper and short wall support system but not dissipates by the plastic strain of agent structure, thereby makes agent structure avoid entering obvious inelastic state and go to pot.
