The measuring appliance amount of deflection table of comparisons
| Survey scale | Corresponding amount of deflection | Design amount of deflection | Transfinite critical value | Remarks |
| 0 | 0 | 86.7 | 124.4 | White area |
| 6.8 | 34.1 | 86.7 | 124.4 | White area |
| 10.6 | 52.6 | 86.7 | 124.4 | White area |
| 17.4 | 86.7 | 86.7 | 124.4 | Yellow region |
| 25.1 | 124.4 | 86.7 | 124.4 | Red color area |
Remarks: being yellow region between some value before desirable design amount of deflection to the critical value that transfinites, certain before the critical value that transfinites
It is red color area after a value.The range of yellow region red color area considers certain degree of safety on the basis of calculating data.
Deflection metrology device design principle: the mid-span deflection and Leading Edge Deformation of simple truss are at approximate proportional relation, Ke Yitong
The variation of measurement end displacement is crossed to speculate mid-span deflection.It can be calculated and not had to by way of changing load in structure design
Data statistics is aggregated to form the amount of deflection table of comparisons, is designed on mandril by the amount of deflection table of comparisons by the corresponding end displacement of amount of deflection
Scale and scheme of tinting.
A kind of application method of above-mentioned truss deflection metrology device, includes the following steps:
1) support rod of first base and truss end is welded, pre-buried slugging in second base and column, such as
Shown in Fig. 5；
2) sleeve is inserted into the mounting hole of second base, as shown in Figure 6；
3) unscrewing end cap, by the pilot hole of mandril insertion second base, sleeve second end is corresponded to quarter by turnbarrel
At " 0 " position of degree, the fixed screw on mounting hole is tightened, fixes sleeve, as shown in Figure 7；
4) when normal use situation, sleeve second end corresponds to the white area of scale；Dust stratification is excessive, close to design load
When, sleeve second end corresponds to the yellow area of scale, should carry out truss deashing immediately at this time；When load transfinites, sleeve
Two port should arrive the red area of scale, and truss forbids upper people at this time, and takes reinforcement measure, as shown in Figure 8.
Advantage: 1. simple structures, it is easy for installation, it is easy to use, it is difficult to solve truss deformation condition in previous use process
The problem of to measure, reminds owner's timely deashing in process of production, guarantees structure safety.2. using being installed after first truss hoisting
The design scheme of measuring appliance, can eliminate construction error, accurately measure the amount of deflection as caused by actual loading.3. by left and right
The amount of deflection difference measurements of two truss structures, it can be determined that whether truss is in spatial warping state, and (the transfiniting of large-span truss is destroyed logical
Normally due to caused by Spatial Instability).
The applicable elements of device: 1. be only applicable to the end of simple truss or continuous trusse across.2. be only applicable to span compared with
Big truss (generally higher than 30m), the small truss end deformation of span is small, and measurement accuracy is low.
Remarks: since the lime stone stockyard charging truss structure form of disparity items is similar, load is similar, and span is similar
(50-58m), can be using unified scale and the deflection metrology device for scheme of tinting, and calculates difference according to each project difference
The amount of deflection table of comparisons.If other large-span trusses use, scale and scheme of tinting should be modified according to calculated result.
Lime stone charging truss span is big, and easy dust stratification, the actual deformed state of truss is difficult to observe.It is scratched by installing truss
Degree measurement precaution device, can intuitively observe whether truss amount of deflection is in the range that design and specification allow, and make structure more
Safety, use are more convenient.
After above-mentioned scheme, the actural deflection of truss approximate can be measured using relatively simple method, and with not
User is reminded to carry out deashing unloading or review reinforcing with color.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
