To sum up, the present invention provides a kind of compact lateral support antidetonation connector composite structure, structure is simple, can be with
Antidetonation lateral support is provided for pipeline layout suspension and support in small space, can effectively be subway in conjunction with BIM designing technique
It stands and other pipeline arrangement amounts is larger, and build the relatively narrow building in the interior space for the arrangement of these pipeline routes and provide
Antidetonation lateral support；And institute's consumption material is few, good economy performance；It is easy for installation, it can effectively improve the installation effect of worker during installation
Rate；In addition, the antidetonation connector composite structure can provide lateral support force for entire antidetonation support hanger structure, entire group
Structure stabilized structure is closed, anti-seismic performance greatly improves, good using rear safety；It is horizontal to be laterally supported on load level seismic force
When, power level is transmitted on structural body, when avoiding inclination lateral support, because of force resolution reason, stress is expanded；Because of drop
The low stress of material, also just reduces the mechanical requirements of material, thereby reduces the cost of material.This kind of antidetonation connector group
Close the lateral seismic support that structure solves that arrangement of the existing technology is intensive, can not install inclination and be connected to structure roof
The problem of antidetonation suspension and support can not be used under environment；And it reduces the complexity of lateral support structure, reduce its cost, mention
Its high installation effectiveness enhances its anti-seismic performance.
On the other hand, the present invention provides a kind of building, including above-mentioned antidetonation suspension and support.
In building of the invention, sky is mounted laterally since the lateral support of antidetonation suspension and support is changed to adaptation 100-500mm
Between horizontal cross support, thus thoroughly solve narrow tight space arrange antidetonation suspension and support, especially its lateral support
The problem of.
In order to further increase the performance that building bears lateral antidetonation shearing force, building is arranged in the middle part of the wall of constructional column
Circle is provided in horizontal direction | binder forms the construction lacing wire net of closure；At the position for having structural column, the antidetonation suspension and support
Lateral support be fixed on the structural column；Lateral support at the position of not structural column, the antidetonation suspension and support is fixed
On the constructional column.
In the present invention, as Figure 7-8, constructional column 503 and circle | the formation such as binder 502 and beam 504 are closed netted
Structure 501 (i.e. construction lacing wire net), the level of antidetonation suspension and support is laterally supported and fixed on constructional column, when an earthquake occurs, transmitting
Horizontal seismic force to antidetonation suspension and support lateral support is delivered to constructional column, carries this part seismic force by constructional column.
From the very first in the structure base slab of this layer, top is connected in beam and/or structure roof constructional column, in the middle part of constructional column, is led to
Cross circle | and binder (it is general in civil buildings often to claim binder, collar tie beam is generally often claimed in the buildings such as subway, is unitedly called in the present invention
For circle | binder) connection reticulates, and general setting is enclosed together | binder, in the height of door, such as 2.3 meters of height.When high (or the layer of wall
It is high) more than 7 meters, twice circle should be set | binder.
In fig. 8,601 be antidetonation suspension and support vertical supporting, 602 for the present invention in lateral support above-mentioned, 603 be vertical
To support.It should be noted that be usually provided with and build a wall between constructional column 503 in Fig. 7, to form different rooms, circle |
Binder 502 is generally arranged at build a wall on, rather than it is hanging it is lofty be arranged between two constructional columns, understand circle in Fig. 7 | binder
Setting, therefore eliminate and build a wall.
In this way, earthquake sheet is passed through constructional column and circle | the construction lacing wire net that binder is formed is born, it is ensured that building is propped up with it
Hanger forms entirety, improves whole shock resistance.
In the present invention, building is preferably that subway station and other pipeline arrangement amounts are larger, and build interior for these pipes
The route building relatively narrow by the space arranged.
In the actual items of the prior art, if it is considered that the comprehensive branch of antidetonation is hung, then the independent manual labour word for selecting manufacturer to provide
Steel carrys out the modes such as bearing capacity.The characteristics of this mode, is: it is at high cost, equipment installation is influenced, while having structural integrity insufficient
Birth defect.Until now, subway station and other pipeline arrangement amounts are larger, and for the arrangement of these pipeline routes in building
The relatively narrow building in space, for antidetonation suspension and support using seldom, majority still uses common suspension and support.
In general, the synthesis suspension and support that existing anti-seismic technology is dedicated to solution pipeline not yet forms whole with building
Body, and improve its whole shock resistance:
1, pipeline layout branch, which is hung, calculates deficiency with whole shock resistance.
Construction stage generally arranges pipeline layout suspension and support according to the actual situation.In principle, comprehensive suspension and support should be fixed on
Structural column, load bearing wall etc. are able to bear the position of lateral shearing force；Meanwhile in principle, corresponding site and building is whole should can be true
Recognize the corresponding load that can bear to meet earthquake resistant level.
In Practical Project practice, since the routing Design of pipeline is all in most cases schematically, in the construction stage
Can substantially adjust, the pipeline branch of design phase hang seismic Calculation perhaps and do not have or because pipeline construction variation greatly due to it is ineffective.
2, the structural integrity of comprehensive suspension and support and building is insufficient.
Existing building design when, can't the design phase provide pipeline synthesis suspension and support design.General pipeline
Comprehensive branch, which is hung, to be completed in the construction stage.It, can not be in other structures in the case where the design of not early period and force analysis
Position, such as beam, column position arrange antidetonation suspension and support.
Meanwhile in the actual construction process, because the perforation of pipeline wall the problems such as, can also constructional column and circle to building
| binder causes the centainly destroying infections such as cutting.To further affect the globality of pipeline layout suspension and support and structure.
3, it can not solve between pipeline and lateral wall or column that distance is limited, lateral suspension and support is difficult to the difficulty of mounting arrangements
Topic.
For this purpose, in another aspect, the present invention provides a kind of method for arranging of antidetonation suspension and support between floors, including following step
It is rapid:
S1: making full use of BIM technology means, building design stage carry out pipeline layout design, realize building structure with
The synchronous coordination that pipeline layout branch is hung；
In this step, BIM technology means are made full use of, pipeline layout design is completed in the design phase, realizes building structure
The synchronous coordination hung with pipeline layout branch.This work, which is equivalent to, just completes virtually building for electromechanical pipeline in the design phase,
Effective pipeline layout layout design can be realized in advance.This is the basis carried out the comprehensive branch of pipeline antidetonation and hang design.
S2: carrying out antidetonation suspension and support and calculate and design, the maximum arrangement spacing of confirmation antidetonation suspension and support；
In this step, carries out antidetonation suspension and support and calculate and design.It, can be according to GB after completing pipeline layout design
50981-2014 builds electromechanical engineering earthquake resistant design code etc., and according to gravity laod, the antidetonation of corresponding area and corresponding building is set
(that is: seismic fortification intensity is 6 degree and 6 degree or more and the building in the area no more than 9 degree, and is included in antidetonation and sets for anti-earthquake intensity
Anti- earthquake intensity 6 degree or less area first class building) carry out antidetonation suspension and support calculating.This will ensure that antidetonation suspension and support longitudinal direction,
It is lateral etc. each to meet antidetonation needs to deployment spacing.
Preferably, in this step, after completing pipeline layout design, Electrical Mechanician can be built according to GB 50981-2014
Journey earthquake resistant design code etc., according to gravity laod, the seismic fortification intensity of corresponding area and corresponding building (that is: is provided fortification against earthquakes strong
The building in area of the degree for 6 degree and 6 degree or more and no more than 9 degree, and include in seismic fortification intensity in 6 degree or less areas
First class building) carry out antidetonation suspension and support maximum spacing calculating.

Take 1.0.
ξ2--- position parameter；The vertex of building preferably takes 2.0, and bottom preferably takes 1.0, is distributed along highly linear；Structure is wanted
The building using time history analysis method supplement calculation is sought, calculated result should be adjusted on schedule.The hypogees such as subway station take 1.0.
αmax--- seismic influence coefficient maximum value；It specifically can be according to the corresponding table value in specification.
K --- shock-resistant slant support angle degree regulation coefficient.When diagonal brace vertical length and horizontal length ratio are 1.00, regulation coefficient
It is taken as 1.00；When diagonal brace vertical length and horizontal length ratio are between 1.00-1.50, regulation coefficient is taken as 1.67；When oblique
When supportting vertical length and horizontal length ratio between 1.50-2.00, regulation coefficient is taken as 2.33；
By calculating above, it can be deduced that the maximum spacing of antidetonation suspension and support arrangement.In the present invention, we are concerned with
The problem of lateral support, therefore, we are also based primarily upon lateral spacing to the calculating of suspension and support spacing and consider.Obtain lateral spacing
