Abstract
The invention provides an infilled wall with build-in cross steel bars and a manufacturing method of the infilled wall, and belongs to the technical field of earthquake prevention and disaster reduction. The infilled wall is located in a frame structure and composed of energy dissipation strips, concrete blocks, a concrete frame, reserved steel tie bars and the cross steel bars. The concrete frame and the cross steel bars are manufactured according to common frames, and meanwhile the reserved steel tie bars are manufactured. The vertical energy dissipation strips are located on two sides of the frame infilled wall, and the energy dissipation strips not only prevent the frame structure from being damaged by the infilled wall and dissipate earthquake energy but also can make tight contact with frame columns and reduce the number of construction procedures. The cross steel bars enhance the shear-bearing capacity of the wall body, enhance overall performance of the wall body and improve energy-dissipating capacity. The infilled wall with the build-in cross steel bars makes full use of the energy-dissipating capacity of diagonal bracing portions and a masonry structure, light materials can be made of industrial waste, an ecological environmental protection effect is achieved, and the infilled wall is suitable for being used in the concrete frame structure and has wide application prospect.
Description
Technical field
The present invention relates to a kind of built-in cross wise reinforcement infilled wall and way, belong to a kind of novel practical, cheap and be applicable to the infilled wall preparation method with cross wise reinforcement and vertical energy dissipating band of frame construction house.
Background technology
Earthquake is one of natural calamity of the serious harm mankind, and it has the features such as sudden, regional and destructive.China is in the multiple phase of earthquake in recent years, and 17 secondary earthquake disasters have only just occurred for 2006, Wenchuan earthquake wherein, and just nearly 6,451 hundred million yuan of the economic losses causing, dead and wounded number reaches more than 10 ten thousand.Earthquake shows, through the engineering structures Overall Anti-Seismic Ability performance of providing fortification against earthquakes, significantly improve, effectively alleviated earthquake disaster, but also show that seismic design also exists many problems simultaneously, for example, for not considering in Anti-seismic Design of Frame Structure that infilled wall has considerable influence to structure in earthquake; Through the frame construction of seismic design, fail to occur ductility " strong column and weak beam " failure mode etc. preferably.
Due to for many years, researcher is mainly devoted to the research of agent structure anti-seismic performance, and it is relatively less on the impact research of structural seismic performance on non-structural elements such as infilled walls, and wall, the interactional complexity of frame and uncertainty etc., to seismic analysis of structures, brought difficulty, therefore in structural calculation and analysis, by filled frame designs simplification, be empty frame construction conventionally, and the cycle is carried out to the stiffness contribution that infilled wall is considered in reduction roughly, this processing mode can not reflect the anti-seismic performance of practical structures truly, for example: the internal force that the interaction of infilled wall and framework has changed agent structure distributes, infilled wall has increased the anti-side rigidity of frame construction, has reduced the natural vibration period of structure, has increased design earthquake effect.When infilled wall brings above-mentioned adverse effect, also can improve the anti-seismic performance of agent structure.First infilled wall, as the first line of defence of providing fortification against earthquakes, destroys by integral body or the dissipation seismic energy that collapses under violent earthquake, alleviates the geological process acting in agent structure; Secondly infilled wall can improve the anti-side rigidity of structure, reduces structure lateral deformation, has avoided agent structure to destroy too early; Last infilled wall effect is equivalent to diagonal brace, has shared a part of earthquake internal force, thereby has reduced the Earthquake Internal Force of frame construction.
From earthquake in the past and test, find two kinds of typical damage models of concrete frame: diagonal angle cracking destruction and bight crush to be destroyed.Along with the globality progress to frame wall filled with masonry, there is the computation model of different simplification infilled walls: for example equivalent single pole diagonal brace model, three-strut model and six rod models.According to the destruction of the principle of different models and actual body of wall, can by the mode of built-in diagonal brace, carry out the mode of transfer force of clear and definite wall frame structure, diagonal brace more has the two-fold advantage of shear wall and frame construction concurrently, is conducive to shockproof requirements.
Infilled wall generally includes brick wall, brick cavity wall or lightweight concrete building block wall etc., generally builds in the reinforced concrete frame of building or steel frame, reserves the space that 150-200mm is high under the structural beams at body of wall top, mends to build tamp by building block oblique top.After Wenchuan earthquake occurs, the expert of China and scholar have carried out careful investigation and research to earthquake, find that many reinforced concrete frame structures with infilled wall have suffered from destruction in various degree, wall segment total Collapse almost wherein, reinforced concrete post fracture.Some expert and scholar advise, and the infilled wall of reinforced concrete frame structure is suitable for Zhou Bianzhu to throw off or employing flexibly connects.In Practical Project, be generally between infilled wall top and Vierendeel girder, to take the modes such as vertical oblique block to avoid outside vertical co-operation at present, between the side of body of wall and structural column, leave the space of 15mm to 20mm, in inside, space, fill in flexible packing material, also do not have other more suitably way guarantee that infilled wall both sides and frame column flexibly connect.The problem that adopts this structure to process is, because body of wall side does not directly contact firmly with structure, reduced the flat lateral stability of infilled wall, even if set up, more socket reinforcing bar infilled wall is connected with agent structure, also be difficult to guarantee the stability outside wall plane, bring the problem in finishing and maintenance simultaneously, and lost the ability of the opposing geological process of body of wall itself.Therefore study in better infilled wall built-in diagonal brace power consumption and infilled wall and be connected the mode consuming energy with framework, there is important social value and economic benefit.
Summary of the invention
