Description
Technical field
The invention belongs to technical field of buildings, it is related to template system, the invention still further relates to cast-in-situ concrete floor.
Background technology
The template of cast-in-situ concrete floor typically adopts full hall scaffold to support, its technical maturity, and reliability is high, but operation is numerous
Miscellaneous, materials are many, and cost is high.
One of improved method is to use Prefabricated stacking floor, replaces template.But Prefabricated stacking floor weight is larger, cost
Height, globality is slightly worse.Meanwhile, when being bearing in prefabricated reinforced concrete shear wall, shelving length is limited by its exposed steel bar, with
Prefabricated reinforced concrete shear wall interacts.
The two of Improving ways are use level support shuttering systems, will the big joist rest of template load in precast beam
Or on wall, cancel or decrease vertical supporting.Especially apply more in steel construction, for example Authorization Notice No. CN202577955
U, the day for announcing：2012.12.5, the Chinese patent of invention entitled " in-situ reinforced concrete slab no support shuttering system ", its
Scheme is：This template system includes girder steel and the bed die template setting gradually from top to bottom, the first pressure pin and the second pressure pin, its
In, the edge of a wing that described girder steel includes web and is located at web end, described web arranges pressure pin connector, described second pressure pin
Two ends be connected with described girder steel by described pressure pin connector；Described first pressure pin is arranged on described second pressure pin；Described
Bed die template is arranged on described first pressure pin, and presses closer on the lower surface on the edge of a wing of described girder steel.And for example Chinese patent《Steel
The bar concrete floor construction hanging erecting by overhang of lower suspention》(Authorization Notice No. CN203755677 U, the day for announcing：
2014.8.6), its scheme is：The U-shaped part in steel structure girder bottom for the setting hanging, the U-shaped part bottom side of being fixed with leads to, and crossbeam installs
In side is logical, the length direction along crossbeam is evenly arranged with column, and column upper end is provided with Os Draconis, and Os Draconis upper end is provided with mould
Plate, template holds out against steel structure girder.Such scheme eliminates profiled sheet or full hall scaffold, time saving and energy saving, reduces cost, but end
Head supporting structure is complicated, and needs to install in the air one by one, and dismounting is still comparatively laborious.
In addition, when cast-in-situ concrete floor span is larger, solid floor haves such problems as many from great, concrete amount, often
Replaced with rib floor.The technical scheme such as non-dismantling formwork or filling block can be used in rib floor, common construction method,
Need the operations such as the aerial installation in scene, drawback is many.
Content of the invention
It is an object of the invention to provide template system, this template system is quick for installation, no vertical supporting or few support；
It is a further object to provide cast-in-situ concrete floor, this cast-in-situ concrete floor convenient, low cost of construction.
Template system of the present invention, be employed technical scheme comprise that, for cast in situ concrete floor, including template and a plurality of
The joist be arrangeding in parallel, at least one strip holder beam-ends head is provided with the outrigger being retained in floor, and outrigger is steel part, and outrigger stretches out
Joist termination, as setting up section, remainder is laminated on joist top surface extension, with joist carried out by securing member removable
Unload connection.So, all or part of construction loads can be transmitted by outrigger, realize horizontal support.
The feature of the present invention also resides in,
Outrigger principal section is U-shaped, L-type, c-type, Z-type or I shape, or outrigger is quarter bend or truss or lath, on outrigger
It is provided with lower logical screw d or nut, bolt passes through screw d or nut rotation on the default through hole in joist termination, with joist top surface
Tightly, joist termination is additionally provided with reinforcement or reinforcement.
Joist is scalable beam, is made up of standard knot and telescopic section, standard knot and telescopic section portions telescope, and intussusception sets up separately
There are multiple pairing pin-and-holes, interspersed bearing pin or bolt in the pin-and-hole of coincidence.
Joist is truss-like joist, and telescopic section end and standard knot lower edge end are provided with hinged detachable web member.
Exempt to seal off side at least provided with one.
The section major part of setting up of outrigger is shelved on girder steel or Prefabricated Concrete beam or prefabricated reinforced concrete shear wall；No longer set other
The vertical intermediate supports of vertical supporting or Jin She 1-2 road.
Also set up time stupefied on joist, secondary stupefied two ends ride upon on joist, secondary stupefied upper completely spread removable template.
Template system is rib floor template system, and template includes non-dismantling formwork, and non-dismantling formwork is specially light concrete hollow strips
Plate or light-duty building block or other filling block, the side wall of light concrete hollow lath or light-duty building block or other filling block and its support of rest
Top surface of the beam constitutes girt strip Cast-in-place concrete die cavity.
Joist top surface is additionally provided with keeper, and keeper is provided with reinforcing bar fixed component and limits light concrete hollow lath or light
Type building block or the limiting component of other filling block, the leg of keeper or bottom surface of support saddle are provided with and fix the lower logical screw of its own
A or screw b or hole clipping, securing member is carried out with the lower logical screw a or screw b of keeper or hole clipping by aperture default on joist
It is detachably fixed.
Template system include at least an integral hoisting modular unit, modular unit include multiple by two or more cross-arm
Or the joist that connecting rod is fixing, the edge of joist top edge rest light concrete hollow lath or light-duty building block or other filling block.
Modular unit comprises more than three joists, the two ends setting outrigger of joist only outside two.
Cast-in-situ concrete floor of the present invention, be employed technical scheme comprise that, the multiple outrigger of interval setting, outrigger at floor supporting
For steel part, parts rest on the girder steel or Prefabricated Concrete beam or prefabricated reinforced concrete shear wall of supporting floor, outside bearing near
It is provided with lower logical screw d or nut.
The feature of the present invention also resides in,
Cast-in-situ concrete floor is rib floor, and rib floor includes the dark beam of close rib and panel and light concrete hollow lath or light-duty
Building block or other filling block, the dark beam of close rib is made up of longitudinal rib beam and gate beam, or is only made up of longitudinal rib beam, and multiple light concretes are hollow
Batten or light-duty building block or other filling block are spaced, between its plate, top of the plate cast concrete form the dark beam of close rib and panel.
Also contain keeper in the dark beam of close rib, keeper be provided with reinforcing bar fixed component and limit light concrete hollow lath or
Light-duty building block or the limiting component of other filling block, on the bearing of keeper or the bottom surface of leg, are additionally provided with and fix itself
