Description
Technical field
This utility model belongs to high building project construction field, is specifically related to a kind of steel pipe column beam column bracket base structure.
Background technology
Core wall structure, belongs to high building structure.It is exactly that periphery is the frame stressing system being made up of beam column, and centre is cylinder (such as elevator), because cylinder is in centre, so referred to as Core Walls Structure, has another name called " framework core wall structure " from the point of view of simply.This kind of structure is advantageous to structure stress, and has the most excellent shock resistance.It is the main flow version that high-rise building is widely used in the world.Meanwhile, the superiority of this structure also resides in can strive for as far as possible spacious use space, makes various assistant service space in the centralized of plane, makes the daylighting position that function of tonic chord volume exclusion is optimal, and reaches that sight line is good, the convenient effect of internal transportation.In core wall structure, as the beam column construction of main load effect, typically pour with armored concrete, simultaneously need to possess higher intensity and load requirement.
Steel pipe column (i.e. steel core concrete column) refers to, fill concrete in steel pipe and formed and steel pipe and core concrete thereof can bear the architectural support structure component of external load effect jointly, different by section form, concrete filled steel tube and quadrate steel pipe column etc. can be divided into, in steel pipe column, the effect of contraction of its inner concrete is made concrete be in three dimension stress state by steel pipe, improves the comprcssive strength of concrete；The concrete of steel duct can be effectively prevented again steel pipe generation cripling.Research shows, the bearing capacity of steel pipe column is higher than corresponding steel pipe column bearing capacity and concrete column bearing capacity sum.Interaction between steel pipe and concrete makes the destruction of steel duct concrete be changed into plastic failure by brittle break, and the ductile performance of component is obviously improved, and energy dissipation capacity is greatly improved, and has superior anti-seismic performance.
Due to the above-mentioned advantage of steel pipe column, therefore the beam column construction of Core Walls Structure usually uses steel pipe column structure to obtain in skyscraper especially high-rise building.But in skyscraper especially high-rise building, the Core Walls Structure beam column construction load using steel pipe column is big, and various aspects of performance requires height, therefore yet suffers from a lot of difficult point in design and work progress.
The patent of the Application No. 201410392150.1 that applicant once applied for, discloses a kind of Large-diameter Steel tubing string suspension column construction method of installation, and it is able to ensure that steel pipe column suspension column construction quality, may be used for the suspension column construction of Core Walls Structure beam column construction steel pipe column.
When the steel pipe column subsequent construction of Core Walls Structure beam column construction, applicant considers the node structure that the bracket arranging annular on steel pipe column connects as steel pipe column and crossbeam, but how this bracket structure is arranged could preferably be improved steel pipe column and crossbeam bonding strength, becomes and has considered problem.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: provide the steel pipe column beam column bracket base structure of a kind of bonding strength that can improve Core Walls Structure beam column and crossbeam.
In order to solve above-mentioned technical problem, this utility model have employed following technical scheme:
A kind of steel pipe column beam column bracket base structure, it is characterized in that, described bracket basis, including between the upper and lower every being fixedly welded on two pieces of steel pipe column tube outer surface in horizontally disposed annular steel facing, upper annular steel facing upper surface to lower endless steel facing lower surface distance less than bracket body thickness, annular steel facing external diameter is less than this body diameter of bracket, annular steel facing peripheral direction is horizontally outward welded with the i shaped steel that one section of cross section is I-shaped, and i shaped steel thickness and width are respectively less than thickness and the width of crossbeam.
So, bracket basis uses doughnut-shaped steel plate processing shaped steel to constitute, it is possible to preferably improves the intensity of the follow-up annular bracket pouring and obtaining, and then improves the bonding strength of Core Walls Structure beam column and crossbeam；I shaped steel, as the key foundation of transverse end head section, drastically increases the bond strength of crossbeam and bracket, improves architecture storey floor entirety weight capacity.
Further, the annular steel facing upper surface level linking of i shaped steel upper surface and top, the annular steel facing lower surface level linking of i shaped steel lower surface and lower section, preferably improves the globality on bracket basis to ensure final bracket intensity.Further, i shaped steel is welded with some along the outward extending beam steel of i shaped steel length direction, so facilitates setting and the subsequent construction of beam steel.Further, beam steel is fixedly welded on the respective uper side surface in i shaped steel upper and lower with the position facilitating welding procedure and fixing point conveniently to vibrate after being positioned at follow-up pouring, and structural strength is high, is beneficial to improve final Building Structure Strength.Further, i shaped steel outer surface is arranged with some stirrups the most in the width direction, and stirrup is intervally arranged along i shaped steel length direction；So can preferably improve subsequent structural intensity, stirrup both sides can also weld the waist muscle extended along i shaped steel length direction further simultaneously, to improve structural strength further.Further, some card muscle it are also associated with on annular steel facing between i shaped steel, clamping be welded and fixed annular steel facing upper surface up after vertically arranged and card muscle upper end bends inwards in the middle part of card muscle, card muscle lower end bend inwards after clamping and be weldingly fixed on lower section annular steel facing lower surface, card muscle annularly steel facing outer surface arc uniform interval is arranged, card muscle middle part inner surface is welded with some arched ribs the most in the horizontal direction, arched ribs middle part is in the arc consistent with annular steel facing outer surface radian, arched ribs two ends are weldingly fixed on stirrup after being folded to along i shaped steel side, arched ribs is uniformly distributed along short transverse.So can preferably improve the follow-up bracket obtained structural strength of position between crossbeam, and the structure bonding strength between crossbeam and bracket.
As optimization, in described bracket basis, annular steel facing surface above and be positioned at i shaped steel uper side surface and be provided with the downward perforation for inserting for vibrating spear.As such, it is possible to be preferably beneficial to bracket pouring construction, improve bracket pouring quality.
In sum, this utility model has simple in construction, it is possible to increase bracket intensity, and then the advantage improving the bonding strength of Core Walls Structure beam column and crossbeam.
