Description

A kind of steel concrete crossbeam antidetonation increases anchor ruggedized construction
Technical field
The utility model relates to a kind of ruggedized construction of concrete beam, and particularly a kind of steel concrete crossbeam antidetonation increases anchor ruggedized construction.
Background technology
Along with earth earthquake zone since getting into the new century gets into new cycle of activity, the global earthquakes disaster takes place frequently.Especially the Wenchuan violent earthquake that took place on May 12nd, 2008 has caused tremendous loss, causes the unprecedented vibrations of the whole society, how to guarantee that the structural seismic safety of building is extremely urgent.
In a large amount of masonry structure buildings, adopt cassette ceiling to be shelved on the building cover structure mode on the building roof beam more.Cassette ceiling is delivered to floor load on its building roof of shelving, has concentrated bigger quality on the building roof beam.Therefore, the building roof beam very easily produces relatively large earthquake inertia force under geological process.According to seimic disaster census and routine inspection, find most existing masonry structures buildings, floor beam the body of wall lay-down location not with the reliable drawknot of masonry structure main body.According to analysis, this can cause in seismic process, and the building roof beam produces inertia displacement, finally causes floor beam to be extracted and the slippage whole slump of getting off from the body of wall of shelving.Cause being shelved on the whole slump of precast floor slab on the beam, cause chain reaction, cause serious disaster to take place.The investigation of all previous earthquake is also verified, and the building roof beam is the weak spot the most of Hollow Block Masonry Structure Anti-seismic.
For this reason, we have worked out steel concrete crossbeam antidetonation and have increased anchor ruggedized construction.Through newly adding the seismic bearing capacity that anchor structure strengthens the building roof beam, finally avoid it under seismic load, to be pulled out destruction, and other destruction is taken place.
The action principle that it is basic; Be direct drawknot effect on the one hand, the building roof beam is become integral body with the body of wall drawknot of masonry structure, the withdrawal force of beam is converted into the pressure to body of wall through anchor structure; Improve withdrawal force and made the stress of time spent body of wall, strengthened anchoring property.On the one hand, steel plate is set in addition through being arranged on the body of wall back side.Its area can cover collar tie beam, constructional column and the building cover structure of masonry structure building.Make the building roof beam receive seismic forces that effect of inertia produces and can be delivered to superstructure through steel plate and get on that the wall in length and breadth that is delivered to vertical member through superstructure again is until being delivered to the basis.Make that the Path of Force Transfer of structural entity opposing geological process is more reasonable, the whole anti-seismic performance of masonry structure building is improved.
