It is resisted against the horizontal part 21a of the 1st truss support angle section 21.As a result, the 1st truss support angle section 21 and the 1st angle section supporting station 25 it
Between relative rotation limited, the 1st truss support angle section 21 can be avoided to be collided with building 2.
On the other hand, when producing the length along truss 3 between the 1st floor 4 of building 2 and the 2nd floor 5
In the case of the relative storey displacement in direction, in small-scale earthquake or middle scale earthquake, the 2nd truss branch of on-fixed portion B is constituted
Angle section 23 is held relatively to move along the length direction of truss 3 with the 2nd angle section supporting station 26.By the movement, edge can be absorbed
The relative storey displacement amount for the length direction of truss 3 can avoid acting on truss 3 excessive compressing force.
In contrast, in the extensive earthquake extremely rarely occurred, relative storey displacement amount increases to and small-scale earthquake
Or the degree that middle scale earthquake can not compare.Therefore, it is impossible to avoid the distance between semifixed portion A and on-fixed portion B substantially
Degree reduces, and only is difficult to absorb relative storey displacement amount by on-fixed portion B.
According to the present embodiment, it is significantly reduced and truss 3 at a distance from due to semifixed portion A between on-fixed portion B
The 1st truss support angle section 21 strongly pressed towards the direction close to the 1st floor 4 in the case of, the pressing force is from pivot
42 transmit via latch 43 towards parts of bearings 41.
Across the latch 43 between pivot 42 and parts of bearings 41, in the width of truss 3 in a manner of orthogonal with pivot 42
Degree horizontally extends on direction, also, reservations 53a, 53b of losing for being formed in latch 43 are located at pivot 42 and bearing portion
The boundary of part 41.
Therefore, when pivot 42 is pressed towards the direction of the 1st floor 4, to across between pivot 42 and parts of bearings 41
Latch 43 lose reservations 53a, 53b acting shear load.When shear-type load is more than to lose breaking for reservations 53a, 53b
When splitting load, latch 43 fractures at the position for losing reservations 53a, 53b.
Pivot 42 is released from relative to the fixation of parts of bearings 41 as a result, and pivot 42 is along guiding groove 45 far from blocking
It is moved on the direction of wall portion 47.As a result, the 1st truss support angle section 21 with pivot 42 together towards the direction close to the 1st floor 4
Mobile and 1 a considerable amount of the 1st gap L absorbs the relative storey displacement amount of the length direction along truss 3.
Thus, even if can avoid acting on truss 3 excessive compressing force if when extensive earthquake occurs, Neng Goufang
Only truss 3 buckle or the breakage of the 1st truss support angle section 21 and the 1st angle section supporting station 25.
Then, with further reference to Fig. 7 to Figure 10 to truss 3, the 1st angle section supporting station 25 when having occurred extensive earthquake
