Background technology
Socket joint type disk buckle type scaffold mainly by raising, lowering, vertical rod, cross bar, the component such as brace form, socket joint type disk is buckled
Formula scaffold is mainly used in falsework, support frame, performing art frame etc., can apply built with room, the multiple fields such as tunnel, overhead, bridge
Construction, application is quite extensive.At present, the domestic detection to scaffold is mainly limited to the mechanics carrying energy of single component
Power detects, but the detection to all single components can not still illustrate the size of the real bearing capacity of integral-scaffold, because
This need to develop a kind of whole group or full wafer scaffold progress mechanics detection that can be to setting up, and the bearing capacity value that it is detected is to applying
Work, which is applied, has more reference value.
The content of the invention
The present invention is in view of the above-mentioned problems, provide a kind of whole group scaffold load carrying capacity test equipment, the experimental facilities can
Be accurately detected it is different set up spacing or it is asynchronous away from scaffold bearing capacity.
According to technical scheme：A kind of whole group scaffold load carrying capacity test equipment, it is characterised in that the bottom of including
Frame, there is the adjustable supporting plate of some spacing and the beam slab for setting up supporting plate, scaffold to be tested to be placed in supporting plate for it
On；
Hold-down devices, it is used to the scaffold in supporting plate is carried out to push experiment.
As a further improvement on the present invention, the hold-down devices have several, and each hold-down devices include peace
Hydraulic jack loaded on supporting plate bottom, the piston rod end of hydraulic jack are fixedly connected with bracket under oil cylinder, bracket two under oil cylinder
End is threadedly coupled an adjusting rod being vertically arranged respectively, and two adjusting rod upper ends are connected by distribution beam, the bottom of distribution beam
Face is pressed in the rod end of scaffold.
As a further improvement on the present invention, the supporting plate bottom surface installation oil cylinder seat, hydraulic jack are installed on the oil
In cylinder seat.
As a further improvement on the present invention, the beam slab upper surface, which corresponds at each supporting plate, is equipped with some positioning
Hole.
As a further improvement on the present invention, the chassis is supported by base.
As a further improvement on the present invention, the base includes bottom plate, the support column being fixed on bottom plate, is uniformly arranged
Stiffener plate in support column surface.
As a further improvement on the present invention, hydraulic pump and control cabinet are set beside the chassis.
As a further improvement on the present invention, the beam slab, supporting plate are strip.
The technical effects of the invention are that：Product of the present invention uses hydraulic jack, and ess-strain automated collection systems are realized
The limit of scaffold is loaded, and the automatic calculating to its displacement acquisition and ess-strain is parsed into picture；Solve at present
Cross bar in scaffold, vertical rod, brace, adjustable base or adjustable bracket can only individually be loaded, and it can not set up complete
Whole scaffold carries out the difficulty of overall loading and the ess-strain observed in its loading procedure；Advantage is that integral-scaffold loading is set
The standby test data made has more the reference significance of Practical Project, and data are relatively reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including bracket 7, liquid under scaffold 1, beam slab 2, chassis 3, supporting plate 4, distribution beam 5, adjusting rod 6, oil cylinder

Case 13 processed etc..
As shown in figure 1, the present invention is a kind of whole group scaffold load carrying capacity test equipment, including chassis 3, it has some
The adjustable supporting plate 4 of spacing and the beam slab 2 for setting up supporting plate 4, scaffold 1 to be tested are placed in supporting plate 4；Lower press fitting
Put, it is used to the scaffold 1 in supporting plate 4 is carried out pushing experiment.
Hold-down devices in product of the present invention have a variety of set-up modes, preferably as follows：
Hold-down devices have several, and each hold-down devices include the hydraulic jack 8 for being installed on the bottom of supporting plate 4, hydraulic pressure
The piston rod end of oil cylinder 8 is fixedly connected with bracket 7 under oil cylinder, and the both ends of bracket 1 are threadedly coupled one and are vertically arranged respectively under oil cylinder
Adjusting rod 6, two upper ends of adjusting rod 6 are connected by distribution beam 5, and the bottom surface of distribution beam 5 is pressed in the vertical rod top of scaffold 1
End.
The bottom surface installation oil cylinder seat 9 of supporting plate 4, hydraulic jack 8 are installed on the oil cylinder seat 9.
The upper surface of beam slab 2, which corresponds at each supporting plate 4, is equipped with some positioning holes 10.
