Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
As shown in Figure 1 to Figure 3, the earthquake-resistant structure of the steel frame with dissipative links of the present utility model and chiasma type central supported Structure includes rectangular steel-tube concrete column 10, girder steel(Including being hinged girder steel 121, rigid connection girder steel 122), dissipative links 14, support bar 16 grade components, constitute the dual lateral resisting structure of support and steel frame.For total, support bar 16 is the 1st road defence line, rate First surrender;Dissipative links 14 are the 2nd road defence line, are surrendered again after the surrender of support bar 16;Girder steel is the 3rd road defence line;Rectangular steel pipe is mixed Solidifying earth pillar 10 is last line of defense, i.e. the 4th road defence line.Steel-frame structure purpose of the present utility model is to lift earthquake-resistant structure Overall anti-seismic performance and Lateral resisting ability.
Further to lift economic benefit:For the girder steel inside earthquake-resistant building structure, use and rectangle are substantially What steel core concrete column 10 was hinged is hinged girder steel 121(It is a small number of it is same with support bar 16 across rigid connection girder steel except).It is hinged girder steel 121 are easy for installing using the benefit being hinged, and will not too much weaken the Lateral resisting ability of system, can be set by non-antidetonation component Meter, without interface ductility demand, width thickness ratios can be C classes section, reduce cost.In the peripheral frame of earthquake-resistant building structure, adopt With the rigid connection girder steel 122 of rigid connection between rectangular steel-tube concrete column 10, and such as Q345 higher-strengths grade steel are used, with Lift bearing capacity, rigidity and the anti-seismic performance of steel-frame structure.
Support bar 16 is spring layer chiasma type support bar 16, is designed according to only tension, more economical.
Rectangular steel-tube concrete column 10 uses rectangular steel pipe, to make full use of the compressive property of concrete, reduces cost, together When be easy to be connected with girder steel.To make full use of high strength steel, more preferable lifting steel structural social benefit, except the special component Outward, girder steel, rectangular steel-tube concrete column 10 typically use such as Q345 higher-strengths grade steel.
Dissipative links 14 are the less beams of span in steel-frame structure, and 1.5 meters of usual span is rigid connection with the post at two ends, is cut Face can be identical with general rigid connection girder steel 122, but material uses such as Q235 strength grades low-yield steel, because relatively low bend The steel for taking point can properly increase the ductility of coupling beam, and enable that dissipative links 14 take the lead in surrendering simultaneously, play energy dissipation capacity.
Support bar 16 can be needed by house type and structural system requirement is arranged, and support bar 16 is hinged and girder steel using two ends With the node of rectangular steel-tube concrete column 10.Support bar 16 is designed by pull bar, and seismic behavior on the basis of anti-seismic grade of the structures by carrying Rise one-level to determine, material uses such as Q235 strength grades low-yield steel, to lift the ductility of support bar 16.
With support bar 16 be located at it is same across the rectangular steel-tube concrete column 10 at rigid connection girder steel 122 and two ends use rigid connection, And sectional dimension is suitably increased than other rigid connection girder steels 122, while using superpower design, so that after the reinforcing of the plasticity of support bar 16 Rigid connection girder steel 122 can be surrendered, and its material uses such as Q345 higher-strengths grade steel, so that the rigid connection girder steel at support bar 16 122 have certain margin of safety.
Rectangular steel-tube concrete column 10 is rectangular steel-tube concrete column, and its filling uses normal concrete, height with concrete Reinforced concrete, lightweight aggregate concrete or self-compacting concrete, recommend using C50 or so strong concrete.
Steel frame with dissipative links of the present utility model has following excellent with the earthquake-resistant building structure of chiasma type central supported Point:
1st, without formwork, do not use reinforcing bar, no-reinforcing-bar colligation operation, concrete to be directly poured in rectangular steel pipe, construct Speed is fast;
2nd, post makes full use of the intensity of steel, and the rigidity of concrete, two kinds of material advantage complementations are collectively formed a kind of efficient Lateral resistant member;
3rd, it is easy to standardization, modularization, factorial praluction reduces site operation link, reduces on-site noise, powder Dirt, waste entrainment, standardization, modularization, the work progress of batch production are easy to ensure component quality, raising engineering quality;
4th, system is dual Lateral Resistant System, possesses multiple defence line, with good anti-seismic performance and anti-lateral displacement performance, energy Enough it is perfectly suitable in the residential architectures such as the house of basic, normal, high intensity area, apartment.
5th, system has taken into full account the difference of structure Component Importance, the difference of seismic behavior.According to the importance of component With the difference of seismic behavior etc., different strength grade materials and section are used to component, the characteristics of taken into full account component, Cost is at utmost reduced while ensureing rational in infrastructure safe and reliable.
6th, system has carried out clearly being distinguished on mechanics for beam, employs different connected modes, is ensuring structure conjunction While reason is reliable, construction is substantially facilitated, save material, reduce cost.
Above example is only a kind of the utility model implementation method therein, and its description is more specific and detailed, but simultaneously Therefore the limitation to the utility model the scope of the claims can not be interpreted as.It should be pointed out that for the ordinary skill of this area For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
