Description
Technical field
The present invention relates to a kind of experimental rig, more particularly to a kind of adjustable rest experimental rig of fastener type template system.
Background technology
Adjustable rest is to insert the vertical rod upper end in template steel pipe strutting system, the structure for accepting top construction loads
Part, can be with the height of adjusting bracket.In Practical Project, in order to reduce shadow of the eccentric load to falsework resistance to overturning
Ring, it is ensured that vertical rod uniaxial force state, while ensureing that vertical rod is in close contact with template, code requirement should be set in rod end can
Adjust rest.
In building template engineering construction, due at the top of Formwork-supportof Fastener-style Steel Pipe vertical rod adjustable rest set it is improper and
Caused template cave-in accident happens occasionally.However, in current specifications, being advised in terms of the construction of the adjustable rest in vertical rod upper end
Surely there is the place of many contradictions.《Construction fastener type steel pipe scaffold technical specification of security》（JGJ130-2011）With《Building
Construction formwork technical specification of security》（JGJ162-2008）Construction on adjustable rest in Formwork-supportof Fastener-style Steel Pipe system
Two kinds of different regulations are given, the 6.1.9 articles regulation adjustable supporting support screw rod of JGJ162 stretches out steel pipe top and cannot be greater than
200mm, but the 6.9.1 articles regulation of JGJ130, the length that top layer horizon bar center line to rest point are stretched out in vertical rod are not to be exceeded
0.5m, the 6.9.6 articles regulation, adjustable rest screw rod extension elongation is no more than 300mm.Obviously,《Construction fastener type steel pipe
Scaffold technical specification of security》The increase of middle adjustable supporting degree of protracting, with《Building construction formwork technical specification of security》In regulation
Clash.It would therefore be highly desirable to carry out the support body experimental study with adjustable rest, to adapt to unlike material new material and not
The requirement that parameter is constructed in template system to adjustable rest is set up with template support body.
The content of the invention
The present invention provides a kind of by the experiment simplified model with adjustable rest regarding to the issue above, according to the broken of experiment
Bad pattern, vertical rod axle power, support body sidesway and ultimate bearing capacity situation, determine the fastener type template system of adjustable rest detailing requiments
Adjustable rest experimental rig.
The purpose of the present invention is realized by the following technical solutions：
Fastener type template system is adjustable rest experimental rig, including cross bar and vertical rod and the frame that is connected by right-angle coupler
Body, the middle part vertical rod upper end of support body is provided with the U-shaped adjustable rest being made up of U-shaped support, screw rod and locking nut, its be it is U-shaped can
Adjust and jack is provided with the reaction frame crossbeam above rest；The lower end of jack is provided with pressure sensor；U-shaped support lower end, locking
The adapting position of the upper and lower ends of nut lower end and top layer cross bar is at least respectively equipped with a foil gauge；Bottom cross bar upper end is adapted to
Position is provided with axle power meter.
The horizontal welding steel of adapting position in described U-shaped support.
The present invention has following advantageous effects compared with prior art：The present invention is by according to practice of construction operating mode and construction
Security incident occurrence cause, it is determined that the experiment simplified model with adjustable rest；Using to the middle vertical rod for carrying adjustable rest
The mode that top applies load is loaded, and jack single-point loading, Protonation constant is divided into preloading stage and hierarchical loading stage.
According to the failure mode of experiment, vertical rod axle power, support body sidesway and ultimate bearing capacity situation, adjustable rest detailing requiments are determined, and
The requirement that unlike material and new material are constructed in template system to adjustable rest is applicable, is effectively solved in building template work
In journey construction, because adjustable rest sets improper at the top of the vertical rod of fastener type steel pipe template support body, caused by template cave-in accident
The problem happened occasionally.The present invention is simple and reasonable for structure, it is easy to construct, and with low cost, with preferable economic benefit and society
Can benefit.

Embodiment
The present invention is described in further detail with reference to specific embodiment, but protection scope of the present invention not by
Specific embodiment is limited, and is defined by claims, in addition, with without prejudice on the premise of technical solution of the present invention, to this
Any modifications or changes that the done those of ordinary skill in the art of invention easily realize can fall into the claim of the present invention
Within the scope of.
Embodiment 1
The adjustable rest experimental rig of fastener type template system of the present invention as shown in Figure 1 and Figure 2, including cross bar and vertical rod are simultaneously
The support body 1 connected by right-angle coupler, the upper end of middle part vertical rod 8 of support body 1 is provided with by 9 groups of U-shaped support 11, screw rod 10 and locking nut
Into U-shaped adjustable rest 3, be provided with jack 2 at the crossbeam of reaction frame 5 of the U-shaped top of adjustable rest 3；And make jack 2 with it is U-shaped
Adjustable rest 3 is in contact, and the lower end of jack 2 is provided with pressure sensor 12；The U-shaped lower end of support 11, the lower end of locking nut 9 and top layer
The adapting position of the upper and lower ends of cross bar 4 is respectively equipped with a foil gauge 14；For testing Deformation Member, the upper end of bottom cross bar 6
Position is provided with the horizontal welding steel 13 of adapting position in axle power meter 7, U-shaped support 11 at 100mm, to prevent the U-shaped deformation failure of support 11.
When specifically used：
Preloading phase：Check whether apparatus of the present invention and measuring instrument etc. can normal works；Make jack and adjustable supporting
Support contact is closely knit hence into normal operating conditions, preloads the general 2kN of payload values.
Formal loading：Confirm after the equal normal work of all measuring instruments, just can carry out formal load phase.Every grade of jack
Load is 5kN, and every grade of load continues 3 minutes, when limiting value of the load numerical value close to test model stability bearing capacity, load
Increment is adjusted to every grade of 2kN, and extends the duration of every grade of load, until strain value does not continue to increase, is further continued for next
Level load, loaded value is gathered through the incoming computer of pressure sensor 8 and obtained.
Unloading phase：After the ultimate bearing capacity of test structure is reached, to proceed data acquisition, continue 5 minutes, treat
The deformation of apparatus of the present invention test structure fully develops, then is unloaded.
Draw conclusion (of pressure testing)：According to the failure mode of apparatus of the present invention test model, support body sidesway, vertical rod axle power and carrying
Power situation, determines that the centerline length a of top layer cross bar 4 is stretched out in rational adjustable rest extension elongation limit value, i.e. middle part vertical rod 8；U
Type is adjustable, and rest 3 stretches out middle part vertical rod length b；Sum of the two is length c of the adjustable rest to the horizontal rod axis of top layer.
Apparatus of the present invention can be tested in the case of different materials, different templates support body set up parameter, with U-shaped adjustable rest
Support body stress performance, the U-shaped adjustable rest obtained in light of the circumstances stretches out vertical rod length and the horizontal pole length of vertical rod stretching
Limitation, foundation is provided for Construction Scheme.
