Description
Technical Field
The utility model relates to a shock attenuation shock insulation field, what specifically say is what relate to is an external power consumption angle steel assembled dog that can be extensive be applied to shock attenuation protection fields such as building house, lifeline engineering, medical equipment.
Background
Most regions of continents in China are located in regions above VII degrees of earthquake intensity, the safety requirement of economic high-speed development in China is in sharp contradiction with the severe earthquake disaster threat faced by vast cities in China, and particularly, the contradiction is excited by huge casualties and property loss caused by a few recent major earthquakes (Wenchuan earthquakes, Jade tree earthquakes and Ludian earthquakes) in China. In large earthquakes, facilities such as medical buildings and the like are also damaged greatly, casualties are further aggravated, and huge social influence is caused. The main tasks of shockproof and disaster reduction of life line engineering in China comprise: the earthquake disaster prevention method strengthens the construction of earthquake monitoring facilities in areas along the national major lifeline engineering, ensures the earthquake safety of the lifeline engineering, and emphatically improves the earthquake disaster prevention capability of major and medium cities and major lifeline engineering. Safety and thinking danger, earthquake damage and earthquake potential safety hazard based on the bridge dog, the utility model discloses strengthen to resist the earthquake effect to the concrete dog from new materials and structural style design emphatically.
The research of the material is not found to be applied to a bridge concrete stop block, so exploratory research is very necessary, the practical technology of the foam metal stop block of the project can generate great economic benefit, the application of foam metal in a large amount is promoted at one time, in addition, for other earthquake key monitoring and defense areas, the technology can greatly increase the safety of the bridge, the indirect economic efficiency is obvious, the scientific basis can be used for the seismic design of common medium and small bridges and even the design of other types of bridges, and the tile is added for the smooth implementation of disaster prevention and reduction tasks and the bricking and tiling of disaster prevention and reduction career.
After the severe earthquake in Wenchuan, numerous scholars at home and abroad find that the earthquake-resistant stop blocks are damaged very commonly and seriously through investigation on the earthquake damage of bridge structures. In Wen river earthquake, be located the plateau bridge in city rainbow mouth country plateau village in river weir city, because the simply supported bridge each strides and simply supports through the pier platform and links to each other, its mode of resisting horizontal seismic force only sets up horizontal dog in pier department and retrains it, and its dog has appeared seriously and has squeezed destruction, can't resist bigger horizontal seismic force effect completely. The Minjiang bridge is located at the Minjiang town 213 where Minjiang is crossed, the earthquake middle bridge rotates clockwise, the displacement directions of the upper structure at two banks are just opposite, and the concrete stop blocks are collided and damaged. The stoppers of the temple plateau bridge and the hundred-flower bridge are seriously damaged, and the like.
The domestic scholars think that the selection of parameters such as the type, the rigidity and the spacing of the stop blocks has obvious influence on the function of the stop blocks in the bridge and the dynamic response of the shock insulation bridge through the analysis of the influence of the beam falling prevention device on the dynamic characteristics of the shock insulation bridge, and verify the influence by taking a three-span continuous beam as an example. The 8 foreign PC bridge anti-falling beam structures are summarized, and the stop block is considered to have better effect on preventing the beam from falling transversely and poorer effect on preventing the beam from falling longitudinally. According to survey, statistics and analysis on the Haicheng earthquake and the Tangshan earthquake, the bridge with the longitudinal and transverse shockproof stop blocks is low in vulnerability, and the function of the stop blocks can be seen. A stopper unit for calculation is established by a method that two nodes at the beam end of the rod unit and the pier beam are respectively driven by the pier beam, and a nail type rubber stopper and a bowl type rubber stopper are designed together with Hushide. Although domestic scholars have conducted so many studies, the chinese regulations still remain an empirical blind area for the design of stops.
The early research on the stop block in foreign countries is carried out, the damage mechanism of the stop block is relatively thoroughly researched, and therefore the specification is relatively perfect. Research has focused on the connection of the stop to the abutment. It is recommended to use the connection mode of connecting the stop block and the abutment by steel bars and adding lubricant on the contact surface to form a weak surface on which the damage occurs, and the limit is mainly realized by friction and connecting the steel bars, thus achieving the purpose of limiting and protecting the abutment. The report provides a calculation formula of the restraint force of the stop block and a calculation formula of the reinforcement area of the vertical reinforcements and the transverse reinforcements in the stop block.
The simple beam bridge with the stop blocks is simplified into a spring-mass model, the self-vibration period, the stop block stiffness (the steel plate and the stop blocks with stiffening ribs behind the steel plate) and the initial clearance of the bridge are used as parameters to be analyzed, three seismic waves E1Centro, Northridge and Farlcfield are selected to be analyzed, and the clearance is suggested to be 3 mm. The effect of bridge stops across seismic zones was analyzed, and three cases were studied: there are no stops, linear elastic stops and non-linear stops. Considering that the existence of the stop blocks changes the stress, when the stop blocks exist and the stop blocks do not exist, the displacement and stress conditions of the abutment and the pier are different, the effect of neglecting the stop blocks is not necessarily safe, the analysis is proposed to be carried out on the two conditions of the linear elastic stop blocks and the non-stop blocks respectively, and the obtained result can provide an upper limit and a lower limit for the condition of the non-linear stop blocks.
Scholars at home and abroad carry out a large amount of researches to the concrete dog, but most of researches are concentrated on the anti-seismic design of the dog self, namely, the collision force of resisting the beam by utilizing the reinforcement, rigidity and the like of the concrete dog self, and the form of filling the rubber gasket is also researched partially to reduce the seismic damage of the dog, but the rubber gasket cannot consume energy, can only reduce the collision rigidity, increases the conversion efficiency of the collision kinetic energy, and the essence still needs the dog to consume energy.
Under the large environment of the development of the assembly type structure, the research and the application of the prefabricated stop block are imperative.
