Description
Technical field
The utility model is related to the technical fields of curtain wall construction, connect more particularly to a kind of portable type curtain wall cross beam and column
Binding structure.
Background technology
It looks first at curtain-wall stand-column and connect present situation with crossbeam
1. code requirement
The Ministry of Construction's on November 14th, 2003, No. 193 bulletin, was issued《Glass Curtain Wall Projects technical specification》JGJ102-
2003, implemented from 1 day January in 2004.
Existing People's Republic of China's professional standard《Glass Curtain Wall Projects technical specification》JGJ 102-2003(J 208-
2003) to curtain wall cross beam connection requirement be：Crossbeam generally segmentation is connect with column, and crossbeam both ends can be stayed with column junction
Go out gap, can also use resilient rubbber cushion, rubber pad should have 20%~35% compression deformation ability or beat note elastic sealant,
To adapt to and eliminate the influence of transverse temperature deformation.Certain stroke is stayed after being installed this requires curtain wall cross beam.
2. common crossbeam connection type
A. crossbeam fixed corner code is fixed on by curtain-wall stand-column using rubber pad+bolt.It is adopted between crossbeam fixed corner code and crossbeam
It is connected with screw, curtain wall cross beam expands with heat and contract with cold to be met by rubber pad deformation.Rubber pad is connected and fixed jointly with connecting corner yard
In on column, rubber pad is between corner brace and column, since rubber pad is connected bolt（Or attachment screw）It squeezes, causes to fix
Rubber pad flexible deformation compressed capability decline afterwards is larger, simultaneously as connecting corner yard is installed simultaneously with rubber pad, causes to install
Inconvenient and corner brace position inaccurate；Since installation gap is too small when in addition also resulting in crossbeam connection, to crossbeam installation
Also result in certain inconvenience.
B. crossbeam fixed corner code is fixed on curtain-wall stand-column by bolt.It is connected by screw bolts between crossbeam fixed corner code and crossbeam.
It is connected by screw bolts between crossbeam and column, there are stress between bolt and column, when crossbeam expands with heat and contract with cold, stress are needed to reach gram
The friction stree between bolt and column is taken, movement can be generated, in this way, when the moment for overcoming friction stree, will produce friction
Noise will produce noise in use in this way, influence the life of user.
C. crossbeam fixed corner code is fixed on curtain-wall stand-column by crossbeam fixed corner code grafting+bolt.Such method solves well
It has determined the problem of expanding with heat and contract with cold of crossbeam.This is that current curtain wall cross beam connect most common connection type with column
D. crossbeam is connect with column uses pin form.There are mainly two types of such modes：1. Elastip pin, pin passes through bullet
Spring force is inserted into curtain-wall stand-column pre-manufactured hole, and pin has part in crossbeam intracavitary；2. pin runs through curtain-wall stand-column, single pin is simultaneously
It is partially left at crossbeam intracavitary；This pin connection type common ground is that pin is contacted with the prefabricated hole wall of column 2.5 ~ 3.5mm wall thickness,
When carrying out cylinder with circular-hole internal-wall Calculation of Contact Stress, most of contact stress is both greater than aluminium alloy section surface contact and answers
Power, there are insecurity for theoretical calculation.
What tri- kinds of modes of abc were all made of is half opening crossbeam, and crossbeam fixed corner code is fixed on curtain-wall stand-column using bolt,
Under the larger situation of cladding glass plate, glass curtain wall crossbeam easy tos produce torsion, meanwhile, opening and half opening section of beam are special
Property is poor for silent crossbeam, and stock utilization is relatively low.D connection types mostly use silent cavity crossbeam, and anti-torsion performance obtains
Good improvement, but require pre- hole position requirement on machining accuracy higher, constructing operation is inconvenient.
The problem of being encountered in engineering
My company's common components formula curtain wall cross beam in Practical Project mostly uses half opening crossbeam, and crossbeam is with corner brace using slotting
Connect structural union.To reduce material cost, crossbeam torsion phenomenon is reduced, my company sets up research and development group's progress technology and attacks
It closes, to the processing of crossbeam anti-torsion to perfection, while reducing certain cost.
Utility model content

Sample, the flexible connection block are inserted into the sliding slot from cross beam sectional bar end and form sliding pair, the flexible connection block with crossbeam
The direction vertical with column side is equipped with through the pin hole for being flexibly connected block；It is fixedly connected on the side of the column section
There are two, size matched bolt corresponding with the bolt hole site, two bolts are inserted respectively into formation pair in two pin holes
Two flexible connection block supports, are fixedly connected between the flexible connection block and cross beam sectional bar by screw.
Preferably, the flexible connection block includes rectangular supporting body, the fixation edge strip positioned at supporting body edge, institute
The sliding slot for the cross beam sectional bar stated include with the matched rectangular main sliding slot of supporting body and with the matched secondary sliding slot of fixation edge strip, pair is sliding
Slot and the notch that main sliding slot connectivity part is sliding slot, secondary sliding slot clamp the edge of fixation edge strip, fixed edge strip major part position
The fixing screws are equipped at notch, at the notch to be fixedly connected block is flexibly connected with cross beam sectional bar.
Preferably, the bolt connect with column section one section is tapping screw thread section, is inserted into flexible connection block pin hole
One section be cylinder, the end face of the cylinder be equipped with interior hexagonal hole, for tapping screw thread section to be screwed on column section
In threaded hole.
Preferably, suit elastic rubber washer, the washer are located at column section side and beam type on the bolt
Between material end face.
The technique effect of the utility model
The portable type curtain wall cross beam and upright post connection structure, crossbeam use the good closing chamber proximate matter section of torsional property,
There is following advantage：
1. crossbeam uses closing chamber proximate matter section, the antitorque characteristic good of closed chamber section proximate matter.
2. crossbeam operates in the case of visual with column attended operation, constructing operation is easy to control；Construction quality energy
It is enough to ensure.
3. two flexible connection blocks are connected as separating connection with two bolts, do not restrict mutually, it is pre- can effectively to make up construction
The error of drilling can guarantee the installation accuracy of crossbeam
4. the bolt threaded hole on column section is located on the inside of column outermost profile wall, maximum reduces glass load pair
The torque of crossbeam gravity, meanwhile, so that crossbeam forward lower comer is generated torsion when receiving gravity, into column before in
Lateral extent is minimum
5. vertical pitch-row accomplishes maximum as possible, reduce contact stress between crossbeam connecting corner yard and screw.
