Description
Technical field
The utility model belongs to building engineering field, is related to assembly concrete Building technology, more particularly to a kind of prefabricated
The upper connecting node of concrete and hung wallboard.
Background technology
Precast concrete out-hung panel, it is by precast concrete wall panel, wallboard and agent structure connector or connecting node
Deng composition, installation on the body construction, rise go along with sb. to guard him, the non-bearing precast concrete out-hung panel of decoration function.
National standard《Prefabricated concrete structure technical regulation》(JGJ1-2014) the 10.1.5 articles regulation：" out-hung panel
Flexible connection is preferably used with agent structure, connecting node there should be enough bearing capacities and adapt to the ability of agent structure deformation "；
《Assembly concrete construction technical standard》(GB/T51231-2016) the 5.9.2 articles regulation：" out-hung panel and agent structure
Connecting node should have enough bearing capacities and adapt to the ability of agent structure deformation ", the 5.9.3 articles regulation：" Aseismic Design
When, the connecting node of out-hung panel and agent structure has not less than agent structure in fortification intensity earthquake in wallboard plane planted agent
The deformability of lower 3 times of the elastic displacement angle between floors of effect." the 5.9.7 articles regulation：" out-hung panel is with agent structure using point branch
When holding connection, joint structure should be met the following requirements：1. tie point quantity and position should be true according to out-hung panel shape, size
Fixed, tie point should not be less than 4, and load-bearing tie point does not answer more than two；2. under external force, out-hung panel is with respect to body junction
Structure horizontal should be able to be slided or rotated in wallboard plane；3. the sliding eye size of connector should be according to perforated bolt diameter, deformation
The factor such as ability need and construction tolerance determines.”
National standard《Precast concrete out-hung panel engineering technology code》The 6.6.3 articles of (exposure draft in 2017)
2 sections of regulations：" connecting node of precast concrete out-hung panel, there should be the three-dimensional regulation energy for eliminating out-hung panel construction error
Power ".
The above provides, is the most base to precast concrete out-hung panel in design, production, construction and the course of receiving
This requirement, it is necessary to strict implement.
Existing technology, it is most of more or less to exist not although meeting above-mentioned defined requirement to a certain extent
The defects of with degree, one is without the three-dimensional regulation ability for eliminating out-hung panel construction error；The second is out-hung panel bottom
The connecting node on end or top does not possess the ability to work for only having flat out of plane constraint to wallboard.Such as：
Example one, in national standard《Assembly concrete construction technical standard》(GB/T51231-2016) the plug-in wall shown
Limit connector outside face mentioned in printed line support connection schematic diagram, solves the problems, such as spacing outside face, that is, solves
The problem of out of plane constraint flat to wallboard, but its plane is interior and retractable is not implemented.Prior art generally use is even
The side of fitting is provided with slotted hole, solves freely stretching for horizontal direction, but for vertically without can Free Transform energy
Power, while also just without the three-dimensional regulation ability for eliminating out-hung panel construction error.
Example two, notification number are " CN 205604464U " Chinese patent literature, to disclose and connect under a kind of exterior wall cladding antidetonation
It is connected at the top of fitting, including the first riser and the second riser being parallel to each other, the first riser and the second riser with transverse slat, transverse slat
One end opens up through hole, and screw rod is installed in through hole, and the one end of screw rod away from the first riser and the second riser is connected with built-in connection,
Transverse slat installs the first nut on the screw rod of built-in connection side, is the advantages of the utility model：
Installation site between Vierendeel girder and exterior wall can be adjusted, requirement when reducing construction to embedded part precision, together
When reduce production and assembling difficulty, be advantageous to improve production and efficiency of construction, the installation site of exterior wall cladding it is fine-tuning, it is ensured that
Seam between exterior wall cladding is neat, the smooth no projecting member of surfaces of wall, is easy to production and transportation, attractive in appearance after installation and not
The interior space is taken, when relative displacement occurring between Vierendeel girder and exterior wall cladding, connector itself can be movable within the specific limits,
Connector stress damage etc. is avoided, but under the exterior wall cladding antidetonation shown in the patent document mentioned in connecting-piece structure schematic diagram
The first nut limit the diminution of distance between undersetting, the connecting node of out-hung panel bottom does not possess and only had to wallboard
The ability to work of flat out of plane constraint.
Example three, national standard atlas《Precast concrete exterior wall cladding》(08SG333,08SJ110-2), the index A of page 33,
Sliding component perforate is vertical slotted hole, after installation is completed in positioning, only adapts to the ability of deformation up and down, is deformed without adaptation level
Ability.That is, its connecting node does not possess the ability to work for only having flat out of plane constraint to wallboard.
Therefore, it is necessary to which a kind of new technical scheme solves this problem, to meet the requirement of the regulation of current national standard,
Ensure precast concrete out-hung panel reliably working.
The content of the invention
Technical problem to be solved in the utility model：Do not possess for existing precast concrete out-hung panel connecting node
Only there is the problem of flat out of plane constraint ability to work to wallboard, there is provided a kind of upper connecting node of precast concrete out-hung panel, solution
Certainly connecting node possesses only the problem of flat out of plane constraint ability to work to wallboard, while has again and eliminate out-hung panel construction mistake
The three-dimensional regulation ability of difference.
The utility model adopts the following technical scheme that：A kind of upper connecting node of precast concrete out-hung panel, it is special
Sign is：Including active plate and upper connector, tapped through hole, active plate are offered at the center of the active plate
