In order to enhance the friction between the clamping plate 31 and the web 72 of the steel beam, referring to fig. 3, a first anti-slip pattern 311 and a second anti-slip pattern 312 are provided on one side of the clamping plate 31 near the flange 71 of the first steel beam 7 or the second steel beam 8, the first anti-slip pattern 311 is oriented parallel to the length direction of the first steel beam 7, and the second anti-slip pattern 312 is oriented parallel to the width direction of the first steel beam 7.
The first anti-slip beads 311 can increase friction of the clamping plate 31 and the flange 71 in the width direction of the steel beam, and the second anti-slip beads 312 can increase friction of the clamping plate 31 and the flange 71 in the length direction of the steel beam. After the first steel beam 7 and the second steel beam 8 are clamped, the first steel beam 7 and the second steel beam 8 are not easy to misplace, and positioning between the first steel beam 7 and the second steel beam 8 is more stable.
Further, referring to fig. 1 and 4, the synchronizing assembly 4 includes a synchronizing bar 41 and a synchronizing member 42. The synchronizing bars 41 are provided in two, one of the synchronizing bars 41 is connected to one of the sets of the pulling claws 32, and the other synchronizing bar 41 is fixed to the other set of the pulling claws 32. One end of the synchronizing member 42 is fixed to one of the synchronizing bars 41, and the other end is fixed to the other synchronizing bar 41.
Under the action of the synchronizing piece 42, the two synchronizing rods 41 move synchronously, and after the synchronizing rods 41 move, the pulling claws 32 of the same group are driven to move, so that the synchronous movement of the pulling claws 32 on the same pressing plate 1 is realized.
Further, referring to fig. 1 and 4, one end of the tightening assembly 5 is connected to the middle of the synchronizing member 42, the synchronizing member 42 includes a first rod 421 and a second rod 422 disposed at an included angle, the middle of the first rod 421 and the second rod 422 are fixed, and the first rod 421 and the second rod 422 are disposed in an "X" shape. One end of the first rod 421 is fixed to one of the synchronizing rods 41, the other end is fixed to the other synchronizing rod 41, one end of the second rod 422 is fixed to one of the synchronizing rods 41, the other end is fixed to the other synchronizing rod 41, and both the end of the first rod 421 and the end of the second rod 422 are adjacent to their corresponding pulling claws 32.
The synchronizing member 42 is composed of a first rod 421 and a second rod 422, four force transmission points are formed, and the tensioning assembly 5 forms a tensile force on the middle portion of the synchronizing member 42, so that the tensile force transmitted by the four force transmission points of the synchronizing member 42 is relatively uniform. And because the ends of the first rod 421 and the second rod 422 are adjacent to the corresponding pulling claws 32, the force transmission point of the synchronizing piece 42 is closer to the pulling claws 32, which is more beneficial to transmitting the force born by the synchronizing piece 42 to the pulling claws 32, so that the clamping force of the clamping plate 31 to the first steel beam 7 or the second steel beam 8 is more stable.
In other embodiments, the synchronizing member 42 may be a rod member, one end of which is fixed to one of the synchronizing bars 41, and the other end of which is fixed to the other synchronizing bar 41.
Further, referring to fig. 5, the tension assembly 5 includes a tension rod 51 and a hinge seat 52, one end of the tension rod 51 is hinged to the synchronizing member 42, and the hinge axis is parallel to the pressing plate 1, and the other end of the tension rod 51 is connected to the linkage assembly 6. The hinge seat 52 is fixed on the pressing plate 1 and is located between the synchronizing member 42 and the linkage assembly 6, and the tension rod 51 is rotatably connected to the hinge seat 52 and the rotation axis is parallel to the pressing plate 1.
When a constructor uses the linkage assembly 6 to press the two tension rods 51 towards the pressing plate 1, the hinge seat 52 forms a fulcrum for the tension rods 51, one hinged end of the tension rods 51 and the synchronizing piece 42 forms a pulling force for the synchronizing piece 42, the tension rods 51 form a pressing force for the hinge seat 52, one side of the pressing plate 1 far away from the tension rods 51 has a trend of being far away from the first steel beam 7 and the second steel beam 8, the pressing plate 1 still clings to the first steel beam 7 and the second steel beam 8 under the action of the connecting assembly 2, the clamping plate 31 moves close to the pressing plate 1 under the action of the pulling force of the tension rods 51, and the clamping plate 31 and the pressing plate 1 clamp the flanges 71 of the first steel beam 7 and the second steel beam 8 together.
In other embodiments, the hinge seat 52 in the present embodiment may be replaced by a support, where the tension rod 51 does not need to be hinged to the support, and the support only supports the tension rod 51, and the support may still serve as a fulcrum of the tension rod 51, so as to achieve the same effect as in the embodiment of the present application.
Further, referring to fig. 5, through holes 511 are formed at positions of the two tension rods 51 corresponding to the linkage assembly 6, and the linkage assembly 6 includes a drop-preventing block 61, a linkage rod 62, a spacer block 23 and a nut 24. The anti-falling block 61 corresponds to one of the through holes 511, and one side of the anti-falling block 61 adjacent to the tension rod 51 is in a spherical surface, and the spherical surface of the anti-falling block 61 is attached to the edge of the through hole 511. One end of the link lever 62 is fixed to the escape prevention block 61, and the other end extends out of the other through hole 511. The cushion block 23 is arranged at one end of the linkage rod 62 far away from the anti-drop block 61 in a penetrating way, one side of the cushion block 23 close to the tension rod 51 is arranged in a spherical surface, and the spherical surface of the cushion block 23 is attached to the edge of the through hole 511. The nut 24 is screwed to the end of the linkage rod 62 near the spacer block 23 for abutting the spacer block 23 against the tension rod 51.
When a constructor screws the nut 24 to enable the nut 24 to be close to the cushion block 23, the anti-falling block 61 continuously extrudes one of the tension rods 51 along with continuous screwing of the nut 24, the cushion block 23 continuously extrudes the other tension rod 51, and the two tension rods 51 continuously press towards the pressing plates 1, so that synchronous movement of the two tension assemblies 5 is realized, and after the clamping pieces 3 on the two pressing plates 1 are clamped, screwing action of the nut 24 can be stopped. After the constructor finishes positioning the first steel beam 7 and the second steel beam, the nuts 24 are screwed along the opposite direction, the extrusion actions of the anti-falling blocks 61 and the cushion blocks 23 are all released, the clamping force of the clamping piece 3 is released, and the constructor can detach the positioning device for high-altitude construction. The locking of the whole positioning device can be realized by only screwing one nut 24, so that the positioning device is convenient to operate and efficient to operate.
It should be noted that, in the actual use process, in order to make the positioning of the first steel beam 7 and the second steel beam more stable, the lamination of the pressing plate 1 and the flange 71 needs to be ensured, and the stress of the four clamping pieces 3 on the same pressing plate 1 is ensured to be uniform, so that the deformation and the service life of the four clamping pieces 3 on the same pressing plate 1 are uniform. Therefore, with reference to fig. 6, assuming that the distance from the axis of the link 62 to the right edge of the flange 71 of the second steel beam (right side in fig. 6) is L 1, the distance from the axis of the link 22 to the right edge of the flange 71 of the second steel beam is L 2, the tension applied to the link 62 is F 1, and the tension applied to the link 22 is F 2, the principle of moment balance is that, in order to ensure that the platen 1 is attached to the flange 71 of the second steel beam:
F1*L1＝F2*L2 (1)
From this, it can be derived that F 1：F2＝L2：L1 (2).
Since the pulling force of the link lever 62 and the connecting rod 22 are derived from the pulling force generated when the nut 24 is screwed, the relationship between the torque used to tighten the nut 24 and the pulling force generated by the nut 24 can be expressed by the following formula:
T＝K*F (3)
where T represents the torque (in newton meters) used to tighten the nut 24, K represents the tightening factor, and F represents the pull (in newton) generated by the nut 24.
The tightening factor K is determined by the geometry and material properties of the nut 24 and depends on factors such as the size of the nut 24, the shape of the threads, and the material. In general, the tightening factor K can be determined experimentally or empirically.
From this formula, we can calculate the torque required to tighten the nut 24 based on the required pull. For example, if a 100 newton pull is desired, a tightening factor of 1.2, then the torque required to tighten is: t=k=f=1.2x100=120 newton×m.
Thus, assuming that the torque used to tighten the nut 24 on the linkage assembly 6 is T 1 and the torque used to tighten the nut 24 on the connection assembly 2 is T 2, the linkage (3) and the equation (2), T 1：T2＝L2：L1.
In the embodiment of the present application, the nuts 24 used for the linkage assembly 6 and the connection assembly 2 may be selected to be the same nuts 24, and when the constructor tightens the nuts 24 of the linkage assembly 6 and the nuts 24 of the connection assembly 2, a torque wrench may be used to enable T1: t2 is as close as possible to L2: l1. Thereby ensuring that the pressing plate 1 is tightly attached to the flange 71 of the steel beam and ensuring that the stress of the four clamping pieces 3 on the same pressing plate 1 is uniform.
Further, the dimension of the relief hole 12 in the width direction of the first steel beam 7 is larger than the dimension of the pull claw 32 in the width direction of the first steel beam 7. The position of the synchronizing lever 41 corresponding to the pulling claw 32 is provided with an adjusting hole 411 for adjusting the pulling claw 32 in the width direction of the first steel beam 7, and the pulling claw 32 is provided with a mounting hole corresponding to the adjusting hole 411. Each group of clamping pieces 3 is provided with two, and two clamping pieces 3 are located the both sides of the web 72 of first girder steel 7 respectively, and the both sides of web 72 of first girder steel 7 all are provided with connecting rod 22, and through-hole 511 and the regulation hole 411 of same side on the same side pulling claw 32 are worn to establish to connecting rod 22.
In order to stabilize the connection between the clamping member 3 and the synchronizing bar 41, in the embodiment of the application, two pulling claws 32 are provided on one clamping plate 31, the synchronizing bar 41 being located between the two pulling claws 32.
