Fig. 1 is structure chart of the present utility model.
In figure: 1, support wall column; 2, bracket is supported; 21, groove; 3, plate-girder; 4, support baseboard; 5, rubber buffer; 51, feet; 6, roof supporting; 7, buffer board; 8, cushion block; 81, conductive tip; 9, rubber column; 10, spring; 11, steel column; 12, concrete.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the braced structures of the hydropower generator laminate beam of the present embodiment, comprise the support wall column 1 being placed in powerhouse of hydropower station, support the side of wall column 1 with support bracket 2 outwardly, the upper surface supporting bracket 2 supports one end of generator floor plate-girder 3, between plate-girder 3 and support bracket 2, device has shock-damping structure, shock-damping structure comprises being installed on and supports rubber column 9 in bracket 2 upper recess 21 and spring 10, rubber column 9 is with through through hole, steel column 11 is plugged with in through hole, the lower end of steel column 11 is stretched into and is supported in bracket 2, namely rubber column 9 is connected with support bracket 2 by steel column 11.
Two springs 10 are symmetrically arranged in the both sides of rubber column 9, the upper surface of rubber column 9 and the upper end of spring 10 are connected with support baseboard 4, support baseboard 4 is arranged in groove 21, its upper surface device has rubber buffer 5, the width of rubber buffer 5 is less than the width of groove 21, and its two feet 51 is placed in groove 21; The upper surface device of rubber buffer 5 has roof supporting 6, and the upper surface of roof supporting 6 supports plate-girder 3; Be filled with concrete 12 in groove 21 below support baseboard 4, spring 10, rubber column 9 are buried in concrete 12.
Between plate-girder 3 and support wall column 1, device has buffer board 7, and the lower end of buffer board 7 extends to rubber buffer 5 and supports in the gap of wall column 1; The lower end device of buffer board 7 has cushion block 8, cushion block 8 is with the conductive tip 81 touched with buffer board 7, the inclined-plane of conductive tip 81 and the inclined-plane of buffer board 7 lower end coincide and touch, conductive tip 81 for the oscillation crosswise on buffer board 7 is transmitted rubber buffer 5, to reduce supporting the shearing force of wall column 1.
