Therefore; in order to promote the application of new type formwork support system; create better economic benefit; more for its stress performance is had sufficient understanding; guarantee the security of form bracing system; protection national wealth and people's life safety are necessary it is carried out stability bearing capacity experimental study system, science.
Summary of the invention
Technical matters to be solved by this invention just provide a kind of can be very easily to the charger of the mechanical property research experiment of form bracing system.
The present invention adopts following technical scheme:
A kind of charger of form bracing system, this device comprises welding together and forms square horizontal bottom girder and vertical bottom girder, be welded with symmetrical two loading frames at horizontal bottom girder and vertical bottom girder, top at two loading frames is connected with reaction beam, be connected with loading equipemtn under the reaction beam, loading equipemtn is connected with transfer beam, and each is connected the two ends, lower flange of transfer beam with the top flange of a distribution beam.
Further, between described reaction beam and the loading frame, all be with bolts between transfer beam and the distribution beam.
Further, be welded with the steel plate that the acting surface size with loading equipemtn is complementary in the top flange of transfer beam, loading equipemtn is connected with this steel plate bolt.
Further, described loading equipemtn is actuator or lifting jack.
Further, be welded with the collar or horse-hof shape stirrup at the two ends, lower flange of distribution beam and the two ends, top flange of horizontal bottom girder.
Further, described transfer beam, distribution beam, horizontal bottom girder and vertical bottom girder are the i-shape steel beam with transverse stiffener.
The invention has the beneficial effects as follows:

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1, shown in Fig. 1-4, the present embodiment discloses a kind of charger of form bracing system, this device comprises welding together and forms square horizontal bottom girder 3 and vertical bottom girder 4, be welded with symmetrical two loading frames 7 at horizontal bottom girder and vertical bottom girder, be connected with reaction beam 6 on the top of two loading frames, be connected with loading equipemtn 9 under the reaction beam, described loading equipemtn is actuator or lifting jack.Loading equipemtn is connected with transfer beam 1, specifically, be welded with the steel plate 5 that the acting surface size with loading equipemtn is complementary in the top flange of transfer beam, loading equipemtn is connected with this steel plate bolt, and each is connected the two ends, lower flange of transfer beam with the top flange of a distribution beam 2.Between described reaction beam and the loading frame, all be with bolts between transfer beam and the distribution beam.Be welded with horse-hof shape stirrup 8 at the two ends, lower flange of distribution beam and the two ends, top flange of horizontal bottom girder.Described transfer beam, distribution beam, horizontal bottom girder and vertical bottom girder are the i-shape steel beam with transverse stiffener.
Below take door frame as example, the concrete steps of using the disclosed charger of the present embodiment that form bracing system is loaded are described:
Each vertical rod bottom of door frame is placed respectively in the horse-hof shape stirrup of horizontal bottom girder top flange, and the top places in the horse-hof shape stirrup of distribution beam lower flange, vertical rod generation slippage and damage mattess when preventing from loading.
When loading, oil pressure pump is exerted pressure and is made the lifting jack elongation, drive moves downward by the transfer beam that steel plate connects, then promoting distribution beam moves downward, because the upper end reaction beam maintains static, masterpiece is used for transfer beam and is delivered to distribution beam, and is final, the load that applies is born by door frame, makes the door frame pressurized.In the time of need to replacing door frame, the oil pressure pump oil return, lifting jack shrinks, and drives transfer beam and distribution beam return, and door frame vertical rod generation resilience removes the destroyed door frame, settles new door frame.
If the transfer beam of this charger, distribution beam and bottom girder are all chosen I32c shaped steel, its relevant parameters is h=320mm, b=134mm, d=13.5, t=15mm, Ix=12170cm
4, Wx=760cm
3, Ix/Sx=26.8cm.
(1) strength checking of charger:
The transfer beam bearing load is maximum, checks as an example of transfer beam example.
The jack pair transfer beam applies the partial face load, supposes that it is a concentrated force.Check the intensity of dangerouse cross-section place beam.Suppose that gantry unit body bearing capacity is 240KN.
The bending strength of beam
Shear strength of beam
Because of the Concentrated load place, ribbed stiffener is set, therefore do not need to carry out partial pressing's strength checking.
So this beam strength all meets the demands.
(2) rigidity checking of charger
Under the Concentrated load, amount of deflection is maximum in the girder span.
Through checking computations, this beam rigidity meets the demands.
(3) ribbed stiffener of charger is arranged
Longitudinal stiffener:
Transverse stiffener:
(4) bearing stiffener of charger
There is larger fixed set load action place the bearing place of beam and top flange, and bearing stiffener should be set.
In sum, the charger of form bracing system disclosed in this invention, cost of manufacture is low, can realize the loading to the various template support system, when loading equipemtn is actuator, make things convenient for the stress-strain curve of acquisition module support system, when loading equipemtn is lifting jack, can obtain loaded value, and can be by the fuel-displaced and oil return of oil pressure pump, realization is to installation and the dismounting of the form bracing systems such as door frame, and is simple and convenient, easy operating.
