Description

A kind of existing building structure bracing means
Technical field
This utility model relates to building structure strengthening device, a kind of existing building structure bracing means.
Background technology
Building aseismicity, refers to be 6 degree and above area must carry out Aseismic Design building at seismic fortification intensity.And some The building building the time limit more long can not reach this standard, it is therefore desirable to installs anti-seismic structure on existing building additional.Anti-seismic structure It is usually and installs reinforced section additional on the beam column of building itself, install flexing part simultaneously additional, but common flexing part is easily heated The impact of swollen shrinkage, the limitation of digestion macroseism.
Utility model content
The purpose of this utility model is to provide a kind of existing building structure bracing means, it is intended to solves existing building and adds Fixing structure flexing part is easily affected by thermal expansion and contraction, it is impossible to the problems such as anti-high wind macroseism.
In order to solve the problems referred to above, this utility model by the following technical solutions, a kind of existing building structure bracing means, Including reinforced section, it is characterised in that: described reinforced section includes transversely strengthening section bar and longitudinal reinforcement section bar, described laterally adds Curable type material is fixed with building structure beam slab, and described longitudinal reinforcement section bar and building structure post are fixed and at the bottom of described longitudinal reinforcement section bar Portion is fixed with building structure ground, is provided with buckling-restrained inclined member, institute between described transversely strengthening section bar and longitudinal reinforcement section bar State buckling-restrained inclined member one end and carry out hinged with transversely strengthening section bar;The buckling-restrained inclined member other end and longitudinal reinforcement section bar Connected by eccentric shaft assembly.
Preferably, in same plane, the diagonal between described transversely strengthening section bar, longitudinal reinforcement section bar, with flexing about Bundle inclined member is parallel.
Preferably, described eccentric shaft assembly includes eccentric shaft, excentric sleeve and eccentric shaft fixture, described excentric sleeve Axis hole is eccentric orfice;Described excentric sleeve is arranged in the axis hole of eccentric shaft fixture.
Preferably, described excentric sleeve and eccentric shaft fixture are equipped with two, are separately positioned on buckling-restrained brace The left and right sides.
Preferably, described eccentric shaft passes two excentric sleeves and buckling-restrained brace.
Preferably, described transversely strengthening section bar is cast in outside building structure beam slab.
Preferably, described longitudinal reinforcement section bar is cast in outside building structure post.
Beneficial effect: install eccentric shaft and eccentric shaft assembly additional, effectively dissolved buckling-restrained part owing to expanding with heat and contract with cold and The deformation produced, strengthens the effect of anti-high wind macroseism.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and specifically This utility model is described in further detail by embodiment.
Fig. 1-5 shows this utility model one existing building structure bracing means, including reinforced section, described reinforcement type Material includes that transversely strengthening section bar and longitudinal reinforcement section bar, described transversely strengthening section bar 1 are fixed with building structure beam slab 3, longitudinally added Curable type material 2 is fixed with building structure post 4, fixes with building structure ground 5 bottom described longitudinal reinforcement section bar 2, described laterally adds Buckling-restrained inclined member 6, described buckling-restrained inclined member 6 one end transversely strengthening it is provided with between curable type material 1 and longitudinal reinforcement section bar 2 Section bar 1 carries out hinged;Buckling-restrained inclined member 6 other end is connected by eccentric shaft assembly with longitudinal reinforcement section bar 2.
Described eccentric shaft 7, for regulating the centre distance between each junction axle and axle, is cut down owing to variations in temperature causes The deflection of buckling-restrained brace 6.
Preferably, in same plane, the diagonal between described transversely strengthening section bar, longitudinal reinforcement section bar, with flexing about Bundle inclined member is parallel.Buckling-restrained brace 6 is for providing the biggest anti-side firm for transversely strengthening section bar 1 and longitudinal reinforcement section bar 2 Degree and bearing capacity.Under earthquake or wind action, the internal force of support back and forth changes under pressurized and tension two states, lotus repeatedly Under load effect, Hysteresis Behavior is poor causes support force drastically to decline, and after installing buckling-restrained brace 6, Hysteresis Behavior improves, and makes building Structure is more firm.
Described eccentric shaft assembly includes eccentric shaft 7, excentric sleeve 701 and eccentric shaft fixture 702, described excentric sleeve Axis hole is eccentric orfice.Described excentric sleeve 701 is arranged in the axis hole of eccentric shaft fixture 702.The side of excentric sleeve 701 is solid Stator is removable, after excentric sleeve 701 passes the axis hole of eccentric mount, the stator taken apart is fixed on excentric sleeve 701 On complete install.
Described excentric sleeve 701 and eccentric shaft fixture 702 are equipped with two, are separately positioned on buckling-restrained brace 6 The left and right sides.
Described eccentric shaft 7 is through two excentric sleeves 701 and buckling-restrained brace 6.Buckling-restrained brace 6 junction is thin Tabular, can go deep in the middle of two eccentric shaft fixtures.
It is outside that described transversely strengthening section bar is cast in building structure beam slab 3.
It is outside that described longitudinal reinforcement section bar is cast in building structure post 4.
In order to avoid the reinforcing bar of original building structure is damaged, when reinforced section is installed, avoids the reinforcing bar of original building structure, plant Enter chemical bolt 8.Increasing reinforcing bar 9 and hoop plate 10 again outside the beam column of original building structure, original building is tied by last casting concrete 11 The beam column of structure and the hoop direct space of plate are filled, it is to avoid corrosion affects structural life-time.
Beneficial effect: install eccentric shaft and eccentric shaft assembly additional, effectively dissolved buckling-restrained part owing to expanding with heat and contract with cold and The deformation produced, strengthens the effect of anti-high wind macroseism.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim Within the scope of.
