Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of steel structure net rack deflection detector.
Background technology
Under prior art, in technical field of building construction, during Long-Span Steel Space Structures unloading, the lower deflection value that specification allows is generally L/250 (L is bond length), and lower deflection value is general larger; As adopted dial gauge to measure, the range of dial gauge generally to be exceeded.
This just needs erection total powerstation to measure, but the erection of total powerstation is subject to again the impact of working-yard environment, is easy to erection inconvenience.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of steel structure net rack deflection detector, and it can measure the larger steel structure net rack of deflection value, and is not subject to the impact of construction environment, easy for installation.
The technical scheme that the utility model adopts is as follows:
A kind of steel structure net rack deflection detector, comprise the measuring mechanism connecting steel structure net rack and the reference mechanism be arranged on steel structure net rack underlying holder, measuring mechanism comprises the connection cord connecting described steel structure net rack, the lower end of described connection cord is provided with counterweight, and described counterweight is provided with rule; Described reference mechanism comprises with reference to backing plate, described reference backing plate is provided with the vertical reference column with reference to backing plate; Described detects with the use of realizing amount of deflection with reference to column and rule.
Connection cord is iron wire, and described counterweight is that 250mm is long, and diameter is the rod iron of 50mm, and the top of described rod iron is provided with suspension ring, the iron wire lower end described in rod iron is connected by suspension ring.
Reference backing plate is 12mm steel plate, and described is the plain bar of 10mm with reference to column, and described plain bar is vertically welded in the edge of described steel plate.
During measurement, adopt steel wire by the colligation of counterweight rod iron in the position that need measure, be fixed on lower floor support with reference to backing plate, ensure that steel plate rule exceeds plain bar at least 10mm substantially drawing close with plain bar.
Before unloading, the initial reading that steel plate rule aligns with plain bar top is recorded; In uninstall process, record often walks the reading of uninstall process.
The beneficial effect that the technical scheme that the utility model provides is brought is:
Installation of the present utility model is very simple, and measuring process is directly perceived, only needs personnel to realize measuring process, and it is convenient to measure, and installation cost is low, and constructability scene makes use immediately.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of steel structure net rack deflection detector of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment one
As shown in Figure 1, a kind of steel structure net rack deflection detector, comprise the measuring mechanism connecting steel structure net rack 1 and the reference mechanism be arranged on steel structure net rack underlying holder, measuring mechanism comprises the connection cord 2 connecting described steel structure net rack 1, the lower end of described connection cord 2 is provided with counterweight 3, and described counterweight 3 is provided with rule 4; Described reference mechanism comprises with reference to backing plate 5, described reference backing plate 5 is provided with the vertical reference column 6 with reference to backing plate 5; Described detects with the use of realizing amount of deflection with reference to column 6 and rule 4.
In the present embodiment, connection cord 2 is iron wire, and described counterweight is that 250mm is long, and diameter is the rod iron of 50mm, and the top of described rod iron is provided with suspension ring 7, and rod iron connects described iron wire lower end by suspension ring 7.
Adopt iron wire, effectively can avoid measuring error.
Reference backing plate 5 is 12mm steel plate, and described is the plain bar of 10mm with reference to column 6, and described plain bar is vertically welded in the edge of described steel plate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
