The meaning being used together.Propose first to install in damper using H profile steel 15 and inner thread sleeve 8 for convenience of installing, changing
It is used in combination in journey, if with the connection of upper and lower concrete connection wall only with inner thread sleeve 8 and spiral shell when damper is installed
Bolt, results in damper absolute altitude and is inconvenient to adjust, but the method facilitates damper to change；If also in damper installation process
It is connected with lower concrete connection wall 5 using H profile steel 15, and upper concrete connection wall 13 is connected by the way of pre-buried dowel, is hindered
Buddhist nun's device absolute altitude is to control, but causes damper to be difficult to change.
Further, described wall sinker 16 is that soft steel shearing type or soft steel shearing type or glutinous bullet type or viscid type disappear
Can device.
Comparative example is conventional mounting method, instantly Vierendeel girder, after the completion of lower shear force wall reinforcing steel bar cage colligation, it is identical in execution conditions
In the case of（Workmen, construction machinery）Respectively with two kinds of localization methods carry out soft steel shearing pattern sinker positioning,
Installment work, is contrasted with regard to installation effectiveness and installation quality, contrasts the survey tool for adopting for stopwatch, spirit level, scale pair
It is more as shown in table 1 below than result：
Compared with conventional mounting arrangements from wall sinker method for rapidly mounting of the present invention, using wall energy dissipating after the present invention
Device is installed, positioning required time is greatly shortened, and greatly improves operating efficiency, while reducing sinker top surface absolute altitude, center
The deviation of position, the levelness control accuracy of sinker are also improved, while improve installation effectiveness and quality.
Above in conjunction with accompanying drawing to the present invention specific embodiment be explained in detail, but the present invention be not limited to it is above-mentioned
Embodiment, in the ken that those of ordinary skill in the art possess, can be with before without departing from present inventive concept
Put that various changes can be made.
