Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below Conjunction is specifically illustrating, and the present invention is further explained.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of energy dissipation apparatus of masonry structure key position, including metope 100, the surface parallelly distribute on of metope 100 has the corresponding window opening 110 in position, and the metope between window opening 110 is set as wall between windows, The surrounding of window opening 110 is provided with the steel nesting 140 of socket masonry wall 150, and the surface of steel nesting 140 is provided with welding manner Integrally formed sleeve bearing 160, sleeve bearing 160 be in setting, each pair of sleeve bearing 160 towards identical, each pair of casing It is screwed with steel 120 inside support 160, the surface of steel 120 is cased with anti-buckling confinement sleeve, hollow between steel 120 Opposition at be provided with turnbuckle 130,130 groups of steel 120, confinement sleeve, turnbuckle inside each pair of sleeve bearing 160 At the energy dissipation reinforcing bar of wall between windows.
In addition, the material that steel nesting 140 uses is carbon steel, the shape of steel nesting 140 is in U-shape.Between adjacent window opening 110 Sleeve bearing 160 be in same level.Steel nesting 140 is provided with inside and outside window opening 110.Turnbuckle 130 is adopted With high-intensitive enclosed turnbuckle.Steel 120 be it is cylindric, steel 120 are consumed energy steel using low yield strength, and steel 120 adopt With LY100 or LY160 or LY225.160 beveled end of sleeve bearing is provided with energy dissipation reinforcing bar arranged in a crossed manner.
A kind of installation method of the energy dissipation apparatus of masonry structure key position,
1) will in the sleeve bearing of setting according to design requirement, adjust direction, it is embedding to be welded on U-shaped ordinary steel in advance It puts on;
2) U-shaped steel nesting is respectively put at the window opening of wall between windows two sides;
3) circle energy consumption steel one end is screwed into circular casing support and is connected, then circle energy consumption steel from its other end Anti-buckling confinement sleeve is put on, is then connect by high-intensitive enclosed turnbuckle with another round energy consumption steel, then Form a complete energy consumption reinforcing bar with tension and compression back and forth, hysteretic energy;
4) step 3 is repeated according to design requirement, energy consumption reinforcing bar is by horizontal direction and intersects and forms local drawing to forming Energy dissipator is pressed, that is, completes the arrangement of the energy dissipation of wall between windows at this;
5) step 2 and step 3 are repeated according to design requirement, two-sided setting inside and outside wall finally completed masonry structure Whole energy dissipation arrangement.
The present invention is arranged by the energy dissipation to many places wall between windows, both can achieve and has been cut to wall between windows progress horizontal direction Area reinforces, and wall between windows can also be formed simultaneously with local small-sized tension and compression energy dissipator, guarantee wall between windows small shake, middle shake even Big shake is lower to enter surrender energy consumption state stage by stage, thus the comprehensive overall stiffness, bearing capacity, ductility for improving masonry structure and Energy dissipation capacity.
The present invention is in Current Building ' earthquake resistant code, about tool of the building structure seismic performance target in masonry structure Body is expanded and is implemented, and especially has reality to important building (such as outstanding historical protective buildings object, small-sized museum of cities and counties) The necessity of application.
For the present invention in small earthquake situations condition, the horizontal direction that wall between windows can be improved is cut area's ability, in, when big earthquake situations condition, Local small-sized tension and compression energy dissipator can be formed at wall between windows, guarantee that wall between windows can enter surrender consumption under middle shake, big shake It can state;Wall between windows are avoided X-shaped cross fracture occur, so that causing building total Collapse, so that comprehensive improve masonry structure Whole endurance and stiffness and ductility the large and medium-sized energy dissipation brace form of building structure is shifted, and extend to miniaturization Masonry structure.Since masonry structure entirety endurance and stiffness is weaker (compared with reinforced concrete structure), thus the antidetonation minimized Energy-consuming device more meets the anti-seismic performance requirement of masonry structure, and the two more matches, and practical performance is strong.
The beneficial effects of the present invention are: production is simple, and it is easy for construction, it both can achieve and wall between windows progress horizontal direction cut Area reinforces, and wall between windows can be formed simultaneously with local small-sized tension and compression energy dissipator, and security performance is excellent, and wall between windows is avoided to occur X-shaped cross fracture, so that cause building total Collapse, thus the comprehensive whole endurance and stiffness and ductility for improving masonry structure, Practical performance is excellent, is a kind of good innovation scheme, is very promising for marketing..
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation It is merely illustrated the principles of the invention described in book, the present invention also has each without departing from the spirit and scope of the present invention Kind changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by Appended claims and its equivalent define.
