Embodiment
The utility model relates to anti-skid test in a kind of design of coupler scaffold test unit and collapse resistance integrated device.This device mainly consists of the following components: the pressure testing machine of pressure testing machine top board 1, pressure test machine bottom board 2 composition, as shown in Figure 2; The test specimen assembly of test specimen montant 6, test specimen cross bar 7, fastener 8 composition, as shown in Figure 4; The distribution beam of distribution beam top board 3, distribution beam montant 4, distribution beam semi-circular steel plate 5 composition, as shown in Figure 6; The test bearing that support base sleeve barrel 9 and base-plate 10 form, as shown in Figure 7; The external displacement measuring device of displacement transducer 11, displacement transducer horizon bar 14, the vertical bar of displacement sensor bracket 15, displacement sensor bracket base 16 composition, as shown in Figure 8; Be welded on the rod iron 13 on fastener, steel wire 12 between connection bit displacement sensor and rod iron, as shown in Figure 3.
Test specimen montant 6 in test, test specimen cross bar 7 and be welded on the rod iron 13 of diameter 8mm on fastener can size in advance needed for factory's well cutting, after well cutting, fastener 8 is tightened to the moment of torsion needed for test in the place of distance montant bottom 100mm, again the center of test specimen cross bar 7 aligning fastener is tightened to required torque and is assembled into the piece installing of fastener test group, then at the cruciform position upper extreme point welding steel rod 13 of fastener 8.After completing the welding of rod iron 13, be placed on the base plate 2 of pressure testing machine by test bearing, then the montant 6 of test specimen is vertically inserted in support base sleeve barrel 9.Trial assignment beam can weld in factory, the montant 4 of distribution beam is welded on the place of the distance distribution beam top board 3 center each 75mm in left and right, and then two pieces of distribution beam semi-ring shape steel plates 5 is welded on the bottom center of the montant 4 of distribution beam.After installing fastener test specimen assembly and test bearing, two of distribution beam pieces of semi-ring shape steel plates are erected at the place of test specimen cross bar 7 apart from each 75mm in left and right, fastener center, ensure that distribution beam is vertically placed in the process of installing.Adjust the height of pressure testing machine top board 1 after installing distribution beam, the top board 1 of pressure testing machine is compressed distribution beam top board 3 gently.The bracket base 16 of displacement transducer can adopt concreting, the scaffolding steel pipe that displacement sensor bracket horizon bar 14 and the vertical bar of displacement sensor bracket 15 all can adopt test used, external diameter 48.3mm, wall thickness 3mm, after displacement sensor bracket horizon bar 14 is adjusted to suitable height, with fastener 81, vertical to itself and displacement sensor bracket bar 15 is connected.After assembling displacement sensor bracket, displacement transducer 11 magnetic stand or adhesive tape are fixed on displacement sensor bracket horizon bar.After fixing displacement transducer 11, be end and rod iron 13 end of the steel wire 12 connection bit displacement sensor 11 of 0.1mm with diameter, after having connected, ensure steel wire 12 straight down.Whole test unit installs later schematic three dimensional views as shown in Figure 1.After whole test unit installs, can test after opening the strain case of pressure testing machine, computer and connection bit displacement sensor.Because the bottom distance on the top and fastener 8 of testing support base sleeve barrel 9 is shorter, then, after completing anti-skid test, collapse resistance test can be carried out.
Be described in detail for an embodiment below.During use, first get out the design of coupler scaffold node needing to do anti-skid test, the desirable 250mm of length of cross bar, the desirable 215mm of length of vertical rod, the local fastening at distance vertical rod bottom 100mm of fastener, connects cross bar and montant forms a test test specimen assembly.The bearing of test adopts diameter 57mm, the weldless steel tube of wall thickness 3.5mm, is highly 70mm, weldless steel tube and a thickness are 20mm, the base plate of long 160mm, wide 160mm is welded to form test bearing.Trial assignment beam by the steel plate of a block length 230mm, wide 100mm, thick 20mm, the semicircular ring steel plate composition of the steel pipe of two long 170mm, diameter 48.3mm, wall thickness 3mm and two wide 20mm, diameter 57mm, wall thickness 3.5mm.The steel pipe of two long 170mm is welded on the place of the distance thickness 20mm steel plate center each 75mm in left and right respectively, and two lines of centres between steel pipe and steel pipe are 150mm.Weld two semicircular ring in the lower end of two steel pipes respectively and form a distribution beam.In order to the little rod iron of a diameter 8mm is welded in the displacement of Measurement accuracy fastener slippage on the top of the cross-shaped part of fastener, little rod iron length is 230mm.A support with concrete bed has been set up in the side of pressure testing machine in order to set up displacement meter, the horizon bar of support connects displacement transducer, the little steel wire that diameter is 0.1mm is drawn at the end of displacement transducer, the other end of steel wire is connected with the little rod iron on fastener, ensures steel wire straight down during connection.Then first test bearing is placed on the base plate of pressure testing machine before test, the montant of antiskid component is inserted the sleeve of test bearing, two semi-ring shape steel plates of antiskid distribution beam lower end are erected at respectively the place of test specimen cross bar distance fastener center 75mm, the top of pressure testing machine is compressed distribution beam top board gently.After installing test specimen, by the support of displacement transducer near pressure testing machine, connect displacement transducer, then be connected between displacement transducer and the rod iron of fastener by little steel wire, displacement transducer is connected with computing machine eventually through strainmeter.Can by the displacement of the displacement channel measurement on pressure testing machine apart from the local test specimen cross bar of fastener center 75mm in the process of test, by the displacement at external displacement sensor fastener center, can be read by the power passage of pressure testing machine and execute stressed data.Because the distance of distance test specimen montant bottom, fastener lower end is 100mm, test specimen montant is inserted in highly in the test support base sleeve barrel of 70mm, so when contacting the sleeve on upper test bearing after fastener lower end slippage 30mm, because the height of sleeve is little, material is good, intensity is high, then fastener finally can destroy under the restriction of sleeve.Whole test unit can complete antiskid and the collapse resistance test of fastener simply, efficiently and accurately.
Whole test unit makes simple, anti-skid test is completed on a test specimen with resisting to break to change to test, save experimentation cost and time, power in process of the test and displacement all adopt full-automatic collection, data are accurate, and personal error is little, can continuous acquisition data in test, data information enriches, and can be the data that follow-up analysis provides detailed.In a word, this experimental provision is compared with collapse resistance test unit with other design of coupler scaffold antiskid existing, has more advantage, is worthy of popularization.
