Technical field
The utility model relates to the verifying attachment that is used for posttension prestressed concrete member ground tackle assemblies such as bridge, is specifically related to a kind of static load anchoring test unit that the whole stressing conditions of single hole and porous ground tackle is detected.
Background technology
The key that presstressed reinforcing steel is used for concrete works is anchoring assembly (being the combination of ground tackle and anchor clamps), anchoring assembly should have reliable anchoring property, enough load-bearing capacity and favorable applicability, to guarantee to give full play to the intensity of presstressed reinforcing steel, and realizing the prestressed stretch-draw operation safely, its quality is related to the quality of whole construction quality.The today that is widely used in building at the presstressed reinforcing steel concrete technology, use for tendon ground tackle, anchor clamps and the connector of each manufacturer production can not guarantee all that product is all qualified, so all should recheck at the presstressed reinforcing steel anchoring assembly of building-site use.Along with science and technology development, more and more stricter to construction quality and technical requirement, being used for heavy construction posttension prestressed concrete member ground tackle assemblies such as bridge, highway and gymnasium is not only the single hole ground tackle, and the porous ground tackle in four holes, six holes even tens holes is also arranged.Especially in recent years the ground tackle that is used for bridge is generally porous.And in the existing test stone, have only detection method and device that regulation is arranged to the single hole ground tackle as GB/T14370-2000 " use for tendon ground tackle, anchor clamps and connector ", the detection method and the device of porous ground tackle is not provided.In work progress, the integral fastening performance of porous ground tackle how, has only by the whole stressing conditions to ground tackle and steel strand wires and could embody.Unit in charge of construction and quality supervised department can't effectively be monitored it, certainly will cause certain potential safety hazard to construction quality.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is to provide a kind of static load anchoring test unit that the whole stressing conditions of single hole and porous ground tackle is detected.
The purpose of this utility model is achieved in that static load anchoring test unit, comprises supporting base, adds the load lifting jack, load transducer, load pedestal and switch board, and switch board is made up of shell, jacking oil pump, electronic controller and display device; Adding load lifting jack, load transducer, load pedestal is arranged on the supporting base on same axial line; Add load jack oil road and connect the jacking oil pump oil circuit; The motor of jacking oil pump is by electronic controller controls; The output circuit of load transducer is connected with the display device of switch board.
Further improve and be that described load pedestal is a cirque structure.
The utility model adopts engineering stretch-draw lifting jack, difference according to tested anchoring assembly stressing conditions, finally control jack tension speed by the electronic controller of regulating the jack oil pump motor, and be connected, realize whole stressed detection porous or single hole anchoring assembly with load transducer; Not only to single, many, also can detect the static load anchoring test of 12 above presstressed reinforcing steels and used ground tackle; Used lifting jack control system realizes that stepless speed regulation, constant speed are advanced jacking and millimeter enters the top; It can not only solve the reinspection problem of presstressed reinforcing steel and ground tackle, anchor clamps and the web member of the actual use in working-yard, and can also carry out quality supervision to the producer that produces presstressed reinforcing steel and corresponding ground tackle, anchor clamps and connector.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
As shown in Figure 1, static load anchoring test unit comprises supporting base 1, adds load lifting jack 2, load transducer 3, load pedestal 4; Also be provided with switch board 5 in addition, switch board 5 is made up of shell 6, jacking oil pump 7, electronic controller 8 and display device 9.Adding load lifting jack 2, load transducer 3, load pedestal 4 is being arranged on the same axial line on the supporting base 1; Adding load lifting jack 2 oil circuits is communicated with jacking oil pump 7 oil line pipes by pipeline; The motor speed of jacking oil pump 7 is by electronic controller 8 controls; The output circuit of load transducer 3 is connected with the display device 9 of switch board 5.
Referring to Fig. 2, the utility model load pedestal 4 adopts cirque structure, is the power that a constraint circular pipe blank projection should be arranged from the stressing conditions of considering circular pipe blank.Load pedestal 4 is located on the supporting base 1, is combined by more piece (selecting 5 joints among the figure), and be to select according to the stressed difference of tested presstressed reinforcing steel 10.Adopt the mould ring of H13 casting to constitute the load pedestal, 300 tons of load pedestals of pressure testing do not have obvious distortion.
Among Fig. 2, ground tackle 12 is six holes, and the anchor clamps 11 clamping six roots of sensation respectively presstressed reinforcing steel is arranged in six holes of ground tackle.
Its principle of work: referring to Fig. 1 and Fig. 2, add load lifting jack 2, load transducer 3, load base 4 with what presstressed reinforcing steel 10 (steel strand wires) passed static load anchoring test unit, it is tight that two ends sandwich in the tested anchoring assembly clamping, and what tested anchoring assembly (being ground tackle, anchor clamps combination) was positioned static load anchoring test unit respectively adds load lifting jack 2 and load base 4 two ends.Select 7 pairs of the gear control jack oil pump motors of electronic controller 8 on the switch board 5 to add load lifting jack 2 and carry out pressure regulation, speed regulating control, so just can control the stretching force that adds load lifting jack 2 well, single or many steel strand wires are carried out drawing tension test.Can measure and observe by GB/T14370-2000 " use for tendon ground tackle, anchor clamps and connector " " 6.2 static test " predetermined items, progressively be loaded on destruction.The result that load transducer 3 will be tested shows by the display device 9 of switch board 5.
In the utility model, add load lifting jack 2, load transducer 3, jacking oil pump 7, display device 9 and select for use the homemade universal product to get final product, electronic controller 8 selects for use Japanese CAUPION series of products comparatively desirable.
