The on-site detection method of the building steel can comprise the following steps:
(1) For steel pipes with the same specification, the same batch number and the same delivery state, each batch of steel pipes adopts a witness sampling mode to sample four steel pipes:
(2) Carrying out surface knocking on the sampled four steel pipes by using a detection device on a construction site by using heavy hammers respectively, wherein each steel pipe is knocked at different positions;
(3) Observing whether the positions of the steel pipes knocked have breakage phenomena such as cracks, scales, fractures and the like;
(4) The knocking position is free from breakage phenomena such as cracks, scales, cracks and the like, and the product is qualified.
After four steel pipes are sampled in a witness sampling mode, the detection device can be used for knocking heavy hammers at different positions of each steel pipe, after knocking, whether the steel pipe is broken such as cracks, scales and breaks or not is observed at the knocking positions of the steel pipes, the quality of the batch of steel pipes can be obtained, and finally the impact resistance detection can be conveniently and rapidly carried out on the steel pipes on a construction site.
Principle of: moving the detection table 1 to a construction site, then taking out the sampled steel pipe, penetrating the steel pipe between the support roller 61 and the compression roller 63, holding one end of the steel pipe far away from the support roller 61 by an operator, then pushing the steel pipe horizontally forwards, driving the support roller 61 to rotate at the moment, enabling the support roller 61 to start to tighten the coil spring 625, enabling the support roller 61 not to rotate any more after the coil spring 625 is tightened to the limit position, and blocking the forward movement of the steel pipe, and enabling the operator to stop moving the steel pipe at the moment;
then, an operator swings the steel pipe upwards by taking the supporting table 6 as a swing center, at the moment, the magnet column 705 on the second sliding block 703 is attracted to the lower side of the steel pipe, so that the steel pipe can drive the second sliding block 703 to move upwards along the sliding groove 71 by utilizing the magnet column 705, then the connecting column 77 on the lower side of the first sliding block 74 can pass through the fixing hole 704, the second sliding block 703 pushes the first sliding block 74 to abut against the upper limit plate 75, meanwhile, the spherical surface 702 of the clamping column 701 is retracted towards the inside of the fixing groove 78 under the action of pressure, the connecting spring 79 is compressed, then the second sliding block 703 can be overlapped with the first sliding block 74 after passing through the clamping column 701, the second sliding block 703 can be positioned between the first sliding block 74 and the clamping column 701, the connecting spring 79 can push the clamping column 701 outwards after elastic recovery, the second sliding block 703 in the middle can be limited by the clamping column 701 and the first sliding block 74, and at the moment, the steel pipe swings to the upper limit position;
then an operator can swing the steel pipe downwards by taking the supporting table 6 as a swing center, and as the clamping column 701 and the first sliding block 74 finish limiting the second sliding block 703 in the middle, after the steel pipe drives the second sliding block 703 to move downwards along the sliding groove 71, the second sliding block 703 can drive the first sliding block 74 to move downwards along the sliding groove 71, and at the moment, the second sliding block 703 can drive the swing arm 3 to swing upwards through the connecting rope 73; after the limiting disc 707 on the connecting rope 73 moves to the position of the upper limit plate 75, the downward movement of the connecting rope 73 can be limited, and as the operator continues to drive the steel pipe to swing downwards, the spherical surface 702 of the clamping column 701 is retracted towards the fixing groove 78 after being subjected to pressure again, and the connecting spring 79 is compressed, so that the second sliding block 703 is separated from the clamping column 701 after passing over the clamping column 701, and meanwhile, the steel pipe pushes the magnet column 705 to abut against the lower limit plate 706, and at the moment, the steel pipe swings to the lower limit position; the connecting rope 73 and the first sliding block 74 lose downward acting force, and then the swinging arm 3 can swing downwards under the action of self gravity and then strike on the steel pipe;
when an operator begins to swing the steel pipe downwards, the steel pipe rotates by a small extent by taking the magnet column 705 as a circle center because of the existence of the compression spring 623, the downward pressure of the steel pipe acts on the magnet column 705, the upward pressure of the steel pipe acts on the compression roller 63, the compression roller 63 moves upwards for a certain distance, the compression spring 623 is compressed, a gap can be generated between the steel pipe and the support roller 61, and the support roller 61 can rotate reversely under the action of the elastic restoring force of the coil spring 625, so that the coil spring 625 is restored to a natural state, and finally the next time the steel pipe is moved forwards on the support roller 61 and then drives the coil spring 625 to tighten;
the swing of the steel pipe takes the positions of the supporting roller 61 and the pressing roller 63 as fulcrums, the distance between the position where an operator holds the steel pipe and the fulcrums is a power arm, the distance between the magnet column 705 and the fulcrums is a resistance arm, and the length of the power arm is larger than that of the resistance arm at the moment, so that the operator can drive the swing arm 3 and the heavy hammer 4 to move upwards with smaller force, and finally, the impact resistance detection of the steel pipe can be further and conveniently carried out on a construction site; meanwhile, when the steel pipe moves forward on the support roller 61 for a distance which is half of the length of the steel pipe, the steel pipe can be completely pulled out of the support roller 61 and then is threaded on the support roller 61 again after reversing, and finally, the power arm can be ensured to have a longer length;
meanwhile, when an operator moves the steel pipe forward each time, the operator can stop moving the steel pipe after encountering the blocked forward movement of the steel pipe, and finally the distance between the steel pipe and the forward movement each time is equal, so that the hammer 4 is favorably knocked at the position with equal distance on the steel pipe, the position on the steel pipe can be detected at equal distance intervals, and the accuracy of the impact resistance detection of the steel pipe can be favorably improved.
