Description
Technical field
The present invention relates to a kind of building construction formwork support system, particularly to a kind of casting concrete floor and
The support system of beam bottom mother plate.
Background technology
Building or the concrete floor of structures, especially when basement is with nonstandard layer, floor height is higher, its
Beam generally also has bigger physical dimension and heavier weight, therefore, its die cavity base plate needs when pouring
Bigger support force, to prevent floor and beam deformed, to guarantee service life of building or structures.
The support of existing beam bottom mother plate is typically by the mode of erecting scaffold, and under beam, side arranges multilayer in length and breadth
Staggered steel pipe for scaffold, is fixed on support column steel pipe by scaffold articulated elements with at the bottom of gripper shoe and beam
End template.So, not only set up workload big, and Height Adjustment is the most inconvenient, has a strong impact on template frame
If operating efficiency.To this end, those skilled in the art are made that corresponding improvement.Chinese patent notification number
CN202672722U, date of declaration on January 16th, 2013, innovation and creation well-known city is " at the bottom of casting beams beam
The supporting construction of template ".The technical scheme of this patent includes lifting support, girder and secondary beam, girder and lifting
All dismountable fixing connected mode is formed by bolt between pillar and between secondary beam and girder.But this
Support structure can not realize early tearing open, to this end, need to improve further.
Summary of the invention
The purpose of the present invention is aiming at deficiency of the prior art, it is provided that a kind of casting concrete floor and beam
End template support system, this support system can realize early tearing open, and after early tearing open, it is torn open late and partly still has casting beams
Good support effect, pours plate little with the risk of distortion of beam, and it is lightweight, convenient in carrying, take and tear effect open
Rate is high.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of casting concrete floor and beam bottom mother plate support system, including at least four even number support column,
At least two girders be arrangeding in parallel and the many piece secondary beams vertical with girder, support column is provided with threaded adjustment
Liftable pillar, liftable pillar top is formed with rectangle cap；Described girder and secondary beam are mainly by aluminium alloy
Or steel section makes；The middle part of described liftable pillar is provided with early dismantling head, and two liftable pillars are by one
Supporting press strip link formation one and tear support group late open, this support press strip is overlapped on two described rectangles respectively by two ends
On the end face of cap；Described girder is overlapped on two adjacent two the described early dismantling heads tearing support group late open；Described
Secondary beam is overlapped on girder described in two parallel two by two ends, the end face of many secondary beams and corresponding two girders
End face be located in the same horizontal plane, and jointly support to have and early tear panel open, early tear end face and the bulging of panel open
In the end face of bar is generally aligned in the same plane.
Using the present invention of preceding solution, during enforcement, multiple support groups of tearing open late are longitudinally disposed along casting beams,
Tear panel multiple morning open and casting beams is formed the supporting section of multiple interruption, early tear panel open and pass through early with girder and secondary beam
Tearing head open to realize early tearing open, after early tearing open, multiple support groups of tearing open late still provide excellent support to casting beams, can effectively drop
The lower bending deformation risk of low casting beams.Simultaneously as girder is overlapped on early dismantling head, secondary beam is overlapped on girder,
All it is formed without fixing connected mode at two, and girder and secondary beam is mainly by aluminium alloy or steel section manufacture,
Early tearing panel open to be also made up of plank or plastic plate, therefore, it is lightweight, convenient in carrying, take that to tear efficiency open high.
Preferably technical scheme, described support press strip is provided with alignment pin；Described rectangle cap is provided with and institute
State the hole, location of alignment pin matched in clearance.Support press strip and rectangle cap to be cooperatively formed by pin and hole and to determine
