2) between adding storey structure and lower building, hookup is set;
3) above adding storey structure is crossed over lower building or whenever layer by layer eminence be provided with the load-bearing crossbeam.
The shock insulation damping device that is arranged between top-out and its basis is the interlayer backing plate of superimposed bed course of elasticity slidably or composite material, and described bed course plate can be continuously or placement at interval.Described shock insulation damping device is rubber or rubber and plastic overlapping layers, or high-strength polytetrafluoroethyl-ne slip compound support plate.The shock insulation damping device that is arranged between each rigidity section horizontal direction of adding storey structure is elasticity overlapping layers slidably, or the backing plate made of composite material, and described bed course plate can be placed continuously or place at interval.The shock insulation damping device that is arranged between each rigidity section vertical direction of adding storey structure recovers mechanism for the elasticity made from elastomeric material or spring.The peripheral shock insulation damping device in basis that is arranged at adding storey structure is the earthquake isolation ditch.The peripheral shock insulation damping device in basis that is arranged at adding storey structure is to use brick, the earthquake isolation ditch that stone or concrete masonry units become, and between two furrow banks, be filled with elasticity energy dissipating material or compressible waste material.Be arranged at the linkwork of hookup between adding storey structure and the lower building for can vertically sliding.Described load-bearing crossbeam is double curvature arch formula, outstanding double curvature arch formula or the outstanding great beam of supporting that skews of drawing.
This storey-added structure for earthquake-resistant low storied building not only structurally improves the ability of building opposing earthquake disaster greatly, has prolonged building application life greatly, but also reduces the construction investment about 20%.Add high building and build again and will reduce investment outlay about 50% than removing the existing building thing.
For further specifying the concrete structure of this storey-added structure for earthquake-resistant low storied building, specifically describe with embodiment with reference to the accompanying drawings.
Its accompanying drawing is original:
Fig. 1-4 is respectively the earthquake resistant structure figure that the lower building that is provided with shock insulation damping device adds layer;
Fig. 5-7 is respectively shown in Fig. 1-4 large span load-bearing crossbeam schematic diagram in the earthquake resistant structure.
In Fig. 1-7: 1 adds a layer earthquake resistant structure; 2 earthquake isolation bed courses; 3 earthquake isolation ditches; 4 elasticity energy dissipating fillers; 5 earthquake isolation elasticity are recovered mechanism; 6 vertical slip dampings; 7 base for posts; 8 lower buildings; 9 load-bearing crossbeams; 10 earthquake resistant structure columns; 11 crossbeams; 12 double curvature arch formula load-bearing crossbeams; The 13 outstanding double curvature arch formula load-bearing crossbeams that draw; The 14 outstanding rest formula load-bearing crossbeams that skew; 15 pulling force rod members; 16 bases; A, B, C are respectively each rigidity section of adding storey structure.
This antidetonation lower building adds layer and increases based on following two aspects:
First aspect:
The earthquake isolation design that this structure proposes is meant the monolithic construction design system that the existing building thing is established by former existing design specifications, changes into the separate type system.Promptly at first come building (1) at superstructure and basis branch, also is separated into a plurality of overlapping rigidity sections in the superstructure of highrise building.Separate the place in superstructure with the basis, and separation place of highrise building superstructure, earthquake isolation material or device are installed, its material can be selected other materials such as rubber pad, rubber plastic pad or composite material for use.(2) on the basis of (1), around the building in the certain distance more than the ground, below ground basis, or the basis is provided with more than the position of shock insulation damping device (material), sets up and cuts off the earthquake isolation hole (ditch) that seismic wave impacts building fully.Earthquake isolation hole can be designed to reinforced concrete structure (member), also can be with other elastomeric material or other composite material.In the earthquake isolation hole elasticity energy dissipator is set, its elasticity energy dissipator can be sealed spring or other elastomeric material etc.In the earthquake isolation design of highrise building superstructure, design and installation elastic shock attenuation recovery device, its elastic shock attenuation recovery device can be made with spring, spring leaf or other elastomeric material.
Second aspect:
On the basis that first aspect is established, could solve and have increasing at double of new and old building thing in the use now.As existing building is 2-10 layer or 10-20 layer, need not remove at assurance existing building thing, and increase the layer to 8-40 under the situation that continues to use.If existing building is not taked the design of earthquake isolation, and blindly increase, in the time of will staying the earthquake outburst, the serious hidden danger of colliding takes place in original building with to increase new construction (member) because vibrations are different mutual, so has endless trouble, and consequence is serious.The present invention propose on the basis of having adopted the earthquake isolation Safety Design, adopt the combination special construction (member) of bridge construction and shock-damping structure that original building is increased at double.Its method is: set up the bearing column that separates with original building around original building, bearing column is design load-bearing basis down, and its basis can be base for post or stripe shape basis, establishes earthquake isolation material or device in the basis.Its shock insulation damping device can be rubber pad, rubber plastic pad or other composite material by multilayer is overlapping makes, the material that adopts French chalk or sliding agent etc. to reduce friction between with the interlayer in the shock insulation damping device of multilayer materials or the overlapping composition of steel plate its role is to better slide damping.The column of setting up around original building gets on along original building, and surpasses more than the existing building height, till the required height of increasing.The floor height place that bearing column and original building are every layer is provided with the slip hookup that can vertically slide, the slip hookup will increase bearing column and original building couples together, when its role is to the earthquake outburst, increase structure (member) and original building and strengthen stable mutually and shake synchronous effect, guarantee to increase integrally-built safety.Increasing the overhead position of bearing column above original building, by the needed floor of increasing whenever layer by layer eminence the load-bearing crossbeam is set, and couple together with increasing bearing column integral body, form as shown in Figure 4 existing building with newly add the new building that high building is an one.The load-bearing crossbeam of increasing on the bearing column gives bearing column to the basis Load Transfer that is increased, and is not pressed on the original building, guarantees the safe handling of original building.The load-bearing crossbeam of increasing on the bearing column can be the load-bearing crossbeam of linear, variable cross-section shape, existing building thing span is bigger meeting, and force the span of increasing the load-bearing crossbeam bigger, existing structure design can't solve, under the very huge again situation of steel work investment, the design that the novel special construction that adopts bridge construction to combine with shock-damping structure solves large span load-bearing crossbeam, the form of its load-bearing crossbeam can be the double curvature arch formula, outstanding draw the double curvature arch formula or outstandingly skew the rest formula, shown in Fig. 5-7.
