Description
Technical field
The invention belongs to Anti-quake Architectural Structure Design technical field, replaceable power consumption is drawn between being related to a kind of skyscraper groove
Beam.
Background technology
With the development of China's urban construction, to skyscraper especially residential housing daylighting, ventilation, the visual field and outward appearance etc.
Requirement, often open up a groove for falling in architectural plane outer end, this concave plane arrangement can weaken structure
Globality, and the rigidity of the lateral resistant member of groove both sides can be obviously reduced, so as to weaken the shock resistance of building.
Now design and some straining beams typically are set in every layer of groove outer end or interlayer, such as Cai Jun is equal to 2008 in periodical
《Shenzhen building and building》In " calculating analysis and the design recommendation of building structure straining beam are set between high residential building groove " for delivering, should
Method construct is simple, and reinforced beam is only set between groove, though the rigidity of lateral resistant member and can change on the outside of reinforcement structure
The globality of kind building.But when earthquake occurs, seismic force is only resisted by its rigidity, and straining beam is in weak part, holds
Destructible.When big shake occurs especially in, straining beam destruction causes surface concrete etc. to drop easily to trigger secondary injury.
Skyscraper especially residential housing because its functional requirement opened up on the outside of building groove have become it is a kind of general
Time way, straining beam between a kind of economically and reasonably groove is designed for improving the anti-seismic performance of building, with important society
And economic benefit.
Chinese patent " replaceable steel coupling beam double-layer plate high-strength concrete combines Coupled Shear Wall " (publication number：
CN203475642U, publication date：2014.03.12) it is related to a kind of steel coupling beam structure for Coupled Shear Wall, but, its requirement
Both sides wall is necessary for double-layer plate outsourcing, and the construction requirement to wall is higher, and general reinforced concrete structure is less fitted
With.Constructively, its energy dissipating portion uses i shaped cross section, can not realize that total cross-section is surrendered in deformation, and web portion partial volume
Easily there is out-of-plane buckling.
The content of the invention
It is an object of the invention to provide replaceable power consumption straining beam and its construction method, a side between a kind of skyscraper groove
Face meets building to globality, the requirement of anti-side rigidity, and on the other hand, straining beam surrender power consumption of being consumed energy when earthquake occurs increases
Big structure damping ratio, reduces effect of the earthquake to agent structure.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：

Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 6, the present invention provides replaceable power consumption straining beam 7 between a kind of skyscraper groove,
Every layer or an interlayer piece power consumption straining beam of setting between the both sides of groove, the every power consumption straining beam 7 are mixed by the reinforcing bar at two ends
The dissipative member at solidifying soil beam 5 and middle part is constituted, and built-in fitting 3 is provided with reinforced beam 5 and built-in fitting 3 stretches out reinforcing bar and mixes
The certain length of solidifying soil beam 5, extension is provided with bolt hole, two piece power consumption core plates 1 and centre of the dissipative member by both sides
Two pieces of floors 2 are constituted, and two pieces of power consumption core plates 1 and floor 2 form the box typed structure positioned at dissipative member center using welding,
The two ends of power consumption core plate 1 are provided with bolt hole 10 corresponding with built-in fitting 3, make dissipative member and the built-in fitting 3 can be by anchoring
Bolt 4 is connected；Wrapped up using packing material in the outside of dissipative member, packing material can be foam heat-insulating board or rock-wool heat insulation plate
Or the one kind in polypropylene extruded sheet, be made one it is hollow box-like, be then wrapped in around dissipative member.
The concrete structure of dissipative member as Figure 1 and Figure 4, including two pieces of power consumption core plates 1 being vertically arranged and two blocks of water
The flat floor 2 for setting, because straining beam two ends mainly produce vertical relative deformation to cause straining beam to destroy in earthquake, so core plate is used
It is vertically arranged, by its curved to cut out of shape dissipation energy.Weakening process is done on power consumption core plate 1, according to actual conditions, can be to power consumption
The upper and lower end edge 8,9 of core plate 1 does circular arc cutting (Fig. 4) or in middle part borehole, and left and right two ends then open up bolt hole 10.Floor 2 sets
Put in the middle of power consumption core plate 1, according to actual conditions, section weakening process can be done to floor, such as in middle part or both sides borehole.Power consumption
Core plate 1 and floor 2 are by Low Yield Point Steel LY100, Low Yield Point Steel LY160, Low Yield Point Steel LY225 or mild steel Q235
Any one is made.Power consumption core plate 1 is welded into entirety with floor 2, is connected with built-in fitting 3 by anchor bolt 4, and reinforced concrete
Native beam 5 turns into an overall cooperation, and built-in fitting 3 uses the assembling form of sandwich structure with power consumption core plate 1, and consume energy core plate
1 left and right end portions be respectively embedded into built-in fitting 3 (built-in fitting 3 includes clamping plate, and clamping plate one end is pre-fixed in the end of reinforced beam 5,
The other end stretches out reinforced beam 5, forms U-shaped clamping structure, such as Fig. 1) in, respective bolt hole position aligns, and then uses anchor
Fixing bolt 4 is connected.
Connection dissipative member determines with the quantity of the anchor bolt 4 of built-in fitting according to calculating, it is ensured that junction has enough
Bearing capacity, when dissipative member deforms, junction is not destroyed.
Referring to Fig. 5, the construction of above-mentioned straining beam is as follows with assembly method：
1) at every layer of building or it is separated by the two sides of 1 layer of groove and pours into a mould one section of reinforced beam 5 respectively,
Distinguish set aside pre-embedded part two sections of ends of the opposite side of reinforced beam in casting process；
2) above-mentioned dissipative member is processed；
3) between dissipative member to be placed in two relative section concrete beams 5 (same layer) after concrete setting, Ran Houli
The two panels power consumption two ends of core plate 1 are connected with the built-in fitting 3 on the reinforced beam 5 of corresponding end with anchor bolt 4.
4) (decoration function is played, and prevents dissipative member part from occurring using packing material parcel around dissipative member
Corrosion etc., dissipative member being capable of Free Transform during earthquake), during packing material is foam or rock-wool heat insulation plate or polypropylene extruded sheet
One kind.
In a word, because the destruction of the building straining beam in earthquake causes mainly due to the vertical relative deformation of wall both sides
, the present invention prevents it from occurring using curved to cut out of shape earthquake energy of the core plate in vertical direction that consume energy by setting floor
Out-of-plane buckling, total cross-section surrender of the section in deformation is realized by pair cross-section weakening, improves its energy consumption effect and material profit
With rate.The present invention is built by setting based on the cushioning members (dissipative member) of the core plate that consumes energy straining beam structure improvement is met
While building thing globality, the safety of straining beam can be ensured under geological process.Meanwhile, thin tail sheep is slided can surrender power consumption, be
Structure provides additional damping ratio, reduces the geological process of agent structure.In addition, simple structure of the present invention, design and construction facilitate, make
Valency is cheap, it is easy to change, and can accomplish safety and economy and deposit.
