Description
Technical field
The utility model relates to building structure, specifically a kind of without inner core super-high building structure.
Background technology
In the super highrise building of China, widely apply framework-core wall structure at present, this structure is by Core Walls Structure and peripheral rare post system framework, post is apart from being generally 8m～12m, post and Zhou Bianliang formation outside framework, and outside framework forms integral body by beam and floor and intercooler core cylinder.Function in Core Walls Structure is mainly escalator, staircase, piping shaft and fire-fighting cup, also communal bathroom etc. can be placed in Core Walls Structure if desired.
Although there is plurality of advantages and be widely used in framework-core wall structure, also come with some shortcomings, for example:
(1) Design of Connecting Beam difficulty.It is little that coupling beam in framework-core wall structure generally has span, stressed special, and the cylindrical shell shear wall rigidity of connection is the feature such as very large again.When structure is subject to horizontal force action, in cylindrical shell, coupling beam is stressed larger, for ensureing that structural safety prevents shear failure, often occurs that coupling beam calculating arrangement of reinforcement value transfinites, and brings difficulty to Cross section Design.And in the more complicated framed-tube structure of plane (as Core Walls Structure eccentric setting), the cross section value size of a certain coupling beam affects greatly the dynamic characteristic of total sometimes, makes the cycle, and the multinomial earthquake index such as Displacement Ratio is difficult to meet code requirement.Therefore the Design of Connecting Beam in plane complicated framework-core wall structure is often more difficult than the Design of Connecting Beam in common shear wall structure.Meanwhile, Core Walls Structure body of wall, as most important lateral resistant member, often due to the needs of door opening, hydrant and pipeline box out, makes the torsional property of structure be subject to weakening to a certain extent.
(2) economy is poor.Core Walls Structure is the main lateral resistant member of framework-core wall structure, require Core Walls Structure in all directions, all to there is larger anti-side rigidity, bear more than 80% horizontal shear, and outside framework is mainly used in bearing vertical load, and shares the sub-fraction horizontal shear of distributing gained by rigidity.The arm of force of the overturning or slip resistance analysis moment of Core Walls Structure depth-width ratio large (comparing with outside framework) is less, can only conduct oneself with dignity by increases, reduce the overturning or slip resistance analysis moment that the mode such as punch strengthens Core Walls Structure, will certainly increase like this steel using amount, increase construction cost.
(3) utility ratio is not good, and plane function is arranged limited.In traditional framework-core wall structure; what the design preferences of Core Walls Structure was considered is the lateral resisting ability of structure; next is only vertical traffic and apparatus arrangement; so just there will be core wall structure and Functional Design to occur deviation; for example the structure design of Core Walls Structure is no problem; but the situation of space affluence or insufficient space appears in the design of plane figure in Core Walls Structure, because the structure design of Core Walls Structure involves the design of whole building structure, adjust very difficult and trouble.For avoiding occurring Core Walls Structure insufficient space and the consideration that strengthens overturning or slip resistance analysis moment, the section area of Core Walls Structure tends to design greatlyr, has reduced thus the utility ratio of building structure.
Therefore design that a kind of to have the comparatively simple super-high building structure of the member designs such as better economy and coupling beam be a technical barrier urgently to be resolved hurrily.

Three of improvement: each layer of described floor comprise some brace summers and be arranged on the floor layer on these some brace summers, described brace summer is girder steel or SRC beam, described floor layer is reinforced concrete floor layer, cassette ceiling layer or composite floor layer etc.
Four of improvement: described floor has at least part brace summer to be connected in a described SRC post of described outer framed-tube structure and the described vertical posts of described bearing wall and frame structure, and at least also have part brace summer to be connected in a described SRC post of described outer framed-tube structure and the described tie-beam of described bearing wall and frame structure.
Five of improvement: in the vertical posts of described bearing wall and frame structure, part vertical posts is common SRC post, part vertical posts is for strengthening SRC post, in the link that the described brace summer of described floor is connected with described bearing wall and frame structure, the link being wherein connected with the reinforcement SRC post of described bearing wall and frame structure is for rigidly connecting, and all the other links are for rigidly connecting or hinged.In the bearing wall and frame structure of this improvement project, common SRC post and reinforcement SRC post are relativeness, and the rigidity of expression reinforcement SRC post, sectional dimension etc. are larger, and common SRC post is less.Size, steel content, concrete thickness, sectional dimension and the shape etc. of concrete common SRC post, reinforcement SRC post need to be determined according to actual demands of engineering.
Six of improvement: described inner frame is rectangular, its place, four angles is provided with vertical posts; Post is not established in the horizontal section of described outer framed-tube structure roughly rectangular and four angles, the interior recess at its four angles is provided with Three S's RC post, with four nearest SRC posts of this Three S's RC post in, and be connected with respectively described brace summer between two distant SRC posts of this Three S's RC post and the vertical posts at described bearing wall and frame structure respective corners place, and this is also connected with at least one the first stiffening girder between brace summer described in two, between this Three S's RC post and nearest first stiffening girder, be also connected with the second stiffening girder; Be respectively equipped with the extended structure towards its adjacent SRC post with two SRC posts of the close together of this Three S's RC post, between each extended structure and nearest the first stiffening girder, be connected with the 3rd stiffening girder.

(2) with respect to the building structure that adopts RC member material-saving and economy more.Because SRC member is stronger than the shear resistant capacity of RC member, therefore in lateral resisting ability, require about equally with weight capacity, and in the roughly the same situation of structure, required steel using amount and concrete amount, the especially concrete amount of the utility model building structure is also less than the building structure that adopts RC member.
(3), because the outer framed-tube structure of the utility model building structure has been born most of horizontal shear, therefore can replace the core wall structure that shear wall encloses formation by frame construction.Traditional framework-core wall structure, because guaranteeing that Core Walls Structure has certain anti-side rigidity, guarantee that again Core Walls Structure has certain ductility to meet the requirement of seismic design, therefore comparatively difficult to Core Walls Structure self design and associated member designs, especially when building height surpasses specification limits requirement, when building structure is irregular, as Core Walls Structure eccentric setting, building structure center of gravity and geometric center are inconsistent, and the difficulty of structure design is large, and are difficult to meet building safety requirement.And that outer framed-tube structure of the present utility model adds the Lateral Resistant System of bearing wall and frame structure is not only reasonable more economically, can meet the requirement of Seismic Design of Building, and whole structure and member designs will be simpler, can adapt to more complicated, irregular building structure, thereby plane figure is more flexible.

The specific embodiment
In the utility model, term " on ", D score, " left side ", " right side ", 'fornt', 'back', " top ", " end ", " interior ", " outward ", " in ", orientation or the position relationship of the indication such as " vertically ", " level ", " laterally ", " longitudinally " be based on orientation shown in the drawings or position relationship.These terms are mainly in order to describe better the utility model and embodiment, are not intended to limit indicated device, element or ingredient and must have particular orientation, or construct and operate with particular orientation.
And above-mentioned part term is except can be for representing orientation or position relationship, also may be for representing other implications, for example term " on " in some cases also may be for representing certain relations of dependence or annexation.For those of ordinary skills, can understand as the case may be the concrete meaning of these terms in the utility model.
In addition, term " installation ", " setting ", " being provided with ", " connection ", " being connected " should be interpreted broadly.For example, can be to be fixedly connected with, removably connect, or monolithic construction; Can be mechanical connection, or be electrically connected to; Can be to be directly connected, or indirectly be connected by intermediary, or be connection inner between two devices, element or ingredients.For those of ordinary skills, can understand as the case may be the concrete meaning of above-mentioned term in the utility model.
In addition, term " first ", " second " etc. are mainly used for distinguishing different devices, element or ingredient (concrete kind is identical with structure possibility also may be different), not for showing or imply relative importance and the quantity of indicated device, element or ingredient.Except as otherwise noted, the implication of " a plurality of " is two or more.
The utility model comprises without inner core super-high building structure: the some SRC posts that are used to form outer framed-tube structure and the some SRC window skirt beams that are arranged on building structure periphery, be arranged on the some vertical posts that are used to form bearing wall and frame structure and some tie-beams of building structure inside, and for connecting some floor plates of outer framed-tube structure and bearing wall and frame structure.The vertical posts of this bearing wall and frame structure and tie-beam both can adopt RC member, can adopt SRC member, but considered the advantage of SRC member, preferentially adopted SRC member.The outer framed-tube structure of employing of the present utility model adds bearing wall and frame structure and has good ductility and fireproof performance.In addition, building structure of the present utility model is preferably applicable in 250 meters of following super highrise buildings, and as used in higher super highrise building, although facade can be opened large hole, other place still can affect facade daylighting.
For forming framed-tube structure, in horizontal plane, these SRC posts along the border (as rectangle, circle etc.) of setting shape with equidistantly or equidistantly mode distribute, and the SRC window skirt beam of each layer connects an adjacent SRC post, the whole tower structure with barrel space service behaviour that forms---be framed-tube structure.The quantity of each member, as the number needs such as a SRC post, SRC window skirt beam, vertical posts, tie-beam, floor will require specifically to determine according to design of building structures.In addition, although outer framed-tube structure is similar frame construction in form, but because it has the spatial behaviour of similar real abdomen tubular construction, its weight capacity, lateral resisting rigidity, torsional rigidity, overturning or slip resistance analysis moment are completely different from the outside framework in general framework-Core Walls Structure.In addition, because the periphery of the utility model building structure has formed framed-tube structure, can more effectively share horizontal shear and overturning or slip resistance analysis moment, bearing wall and frame structure only need be born compared with the horizontal shear of small part and overturning or slip resistance analysis moment, therefore can be designed to form of structure comparatively simple, with load-bearing, act as main tower structure.
SRC(Steel Reinforced Concrete, is called for short SRC) member is also referred to as Steel Reinforced Concrete Members, is in the arranged around reinforcing bar of shaped steel the structure of concreting.Existing research shows that the inside shaped steel of SRC member and external wrapping concrete form integral body, jointly stressed, and its stress performance is better than the simple superposition of these two kinds of structures.Compare with steel work, the external wrapping concrete of SRC member can prevent the cripling of steel member, and can improve the integral rigidity of steel member, significantly improves the plane torsion flexural property of steel member, and the intensity of steel is given full play to.In addition, external wrapping concrete has increased durability and the refractoriness of structure greatly.With RC(Reinforced Concrete, abbreviation RC) structure is compared, owing to having configured shaped steel, improved the bearing capacity of member, especially adopt the SRC member of real abdomen shaped steel, its shear-carrying capacity improves a lot, and the brittleness while greatly having improved sheared destruction has improved the anti-seismic performance of structure.
On the one hand, building structure of the present utility model is with respect to traditional framework-core wall structure material-saving and economy more.The core shell structure of traditional framework-core wall structure, because the arm of force is less, in order to reach the overturning or slip resistance analysis moment of designing requirement, need to increase the deadweight of core wall structure, so this is a kind of not only uneconomical but also unsafe lateral resisting structure system.And the utility model adopts outer framed-tube structure as main lateral resisting structure, its arm of force is longer than Core Walls Structure, with relatively little deadweight, just can provide enough overturning or slip resistance analysis moment.Therefore building structural steel amount of the present utility model, concrete amount are lower, more economically.
On the other hand, building structure of the present utility model is with respect to the building structure that adopts RC member material-saving and economy more.Because SRC member is stronger than the shear resistant capacity of RC member, therefore lateral resisting ability, with weight capacity etc. about equally, and in the roughly the same situation of structure, required steel using amount and concrete amount, the especially concrete amount of the utility model building structure is fewer than adopting the building structure of RC member.
In addition,, because the outer framed-tube structure of the utility model building structure has been born most of horizontal shear, frame construction that is therefore can be with shear resistance weak and that be mainly used in load-bearing replaces the core wall structure that shear wall encloses formation.In traditional framework-core wall structure, because guaranteeing that Core Walls Structure has certain anti-side rigidity, guarantee that again Core Walls Structure has certain ductility to meet the requirement of seismic design, therefore comparatively difficult to Core Walls Structure self design and associated member designs, especially when building height surpasses specification limits requirement, when building structure is irregular, as Core Walls Structure eccentric setting, building structure center of gravity and geometric center are inconsistent, and the difficulty of structure design is large, and are difficult to meet building safety requirement.And outer framed-tube structure of the present utility model adds bearing wall and frame structure, not only can meet the requirement of Seismic Design of Building, and whole structure and member designs will be simpler, can adapt to more complicated, irregular building structure.
The lateral rigidity of the outer framed-tube structure of the utility model building structure is greater than bearing wall and frame structure lateral rigidity, in lateral rigidity ratio, bear respectively corresponding proportion (manys') horizontal shear, the horizontal shear that outer framed-tube structure is born is greater than the horizontal shear that bearing wall and frame structure is born, outer framed-tube structure need to be born the horizontal shear that surpasses 50%, in certain embodiments, outer framed-tube structure has been born and has been surpassed 60%, 70%, even 80% horizontal shear.Just contrary in traditional framework-core wall structure, its Core Walls Structure has been born most horizontal shears, and outside framework is only born very little a part of shearing, and this is a kind of uneconomic lateral resisting structure system.Building structure of the present utility model can provide with less deadweight larger overturning or slip resistance analysis moment larger, therefore material-saving, economy more.
Further, in order to form the tubular construction of frame cartridge form, realize the spatial behaviour of similar real abdomen cylindrical shell, outer framed-tube structure need to meet some requirements.For example post is apart from being greater than 4m, and the long limit of column section should be arranged along barrel direction, can adopt T-shaped cross section if desired; Hole area should not be greater than 60% of metope area, and the ratio of hole depth-width ratio and floor height and post distance is close etc.But owing to comparing with RC member, SRC member has stronger vertical bearing capacity and shear resistance, therefore, the in the situation that of roughly the same mechanical property requirements, the section area of SRC member will be less than the section area of RC member.Therefore the utility model adopts the outer framed-tube structure that SRC post, beam form, and more Large Column Spacing and the rate that punches more greatly can be set, and avoids original framed-tube structure because of post distance and the too small problem that affects the view visual field and daylighting of rate that punches.The post of the one SRC post of outer framed-tube structure of the present utility model is apart from being set to be greater than 4m and be less than 6m, and the deck-molding of the SRC window skirt beam of outer framed-tube structure is 0.8m to 1.3m, and preferably deck-molding is 0.9 to 1.2m.The rate of punching of outer framed-tube structure is 40% to 60%, and the rate that preferably punches scope is 55% to 60%.Because fireproof performance and the endurance quality of SRC member are better than RC member and steel member, the framed-tube structure that therefore adopts SRC member to form also has better fireproof performance simultaneously.
Below in conjunction with embodiment, building structure of the present utility model is described further.
embodiment mono-.
As shown in Figures 1 to 3, comprising without inner core super-high building structure of the present embodiment: the outer framed-tube structure being combined to form by a SRC post and SRC window skirt beam 22, the bearing wall and frame structure being combined to form by vertical posts 11 and tie-beam 12, and for connecting some floor plates of outer framed-tube structure and bearing wall and frame structure.This bearing wall and frame structure eccentric setting, its geometric center departs from the geometric center of housing cylinder, and the geometric center of bearing wall and frame structure is positioned at the region, northwest of outer framed-tube structure as shown in Figure 3.If adopt traditional framework-core wall structure, the Design of Connecting Beam between the design of inner core cylinder so, outside framework and inner core cylinder is by very complex, and design difficulty is very large.After but the housing cylinder of using the present embodiment instead adds the structure of inner frame, because inner bearing wall and frame structure is mainly used in load-bearing, only bear sub-fraction horizontal shear, so Design of Connecting Beam between outer framed-tube structure and bearing wall and frame structure, and the design of bearing wall and frame structure itself will be quite simple, make the plane figure of building structure more flexible.
As shown in Figure 3, the outer framed-tube structure cross section of the present embodiment is rectangular, the consideration in outward appearance and folding corner region view, and post is not established at its four angles.Respectively there are 12 posts in the east of outer framed-tube structure, southern side apart from being a SRC post 21 of 4.2m, and respectively there are 8 not SRC posts 21 of equidistant post west, north side.Wherein, outer framed-tube structure west side from top to bottom the post of the 1st to a 3rd SRC post 21 in (from north orientation south to) apart from being 4.2m, 3rd, the post of a 4th SRC post 21 is apart from requiring to expand as 3 across (being 12.6m) because of facade view, 4th, the post of a 5th SRC post 21 is apart from expanding as 2 across (being 8.4m), and the post of the 5th to a 8th SRC post 21 distance is normal 4.2m.The one SRC post 21 of (aspect from West to East) from left to right of outer framed-tube structure north side is arranged and is arranged similar with a SRC post 21 in west side.Be understandable that, the shape of housing cylinder, inside casing cylinder also can be arranged to circle etc.
As shown in Figure 3, the horizontal section of the bearing wall and frame structure of the present embodiment is rectangle, and the vertical posts 11 at its four angles is for strengthening SRC post, and all the other are common SRC post.The vertical posts 11 of bearing wall and frame structure is arranged symmetrically, and for its either side, centre is provided with the common SRC post of two vertical posts 11(that is spaced apart 4.2m), the vertical posts 11(in these corresponding bights of two SRC posts distance strengthens SRC post) spacing is two across, i.e. 8.4m.The SRC post at place, four angles of bearing wall and frame structure can adopt L-type post.
