[0021] EMBODIMENT

[0022] Referring to Figs. 1-3 As shown in the figure:

[0023] The utility model provides a kind of node plate device of auxiliary steel structure tensioning, it include: tensioning node base 10, tensioning jack 31, tensioning cable 41 and traction cable 42.

[0024] When being applied specifically, tensioning node base 10 is installed on the steel truss to be rectified A, generally by bolt connection, or direct welding.Tensioning jack 31 is installed on tensioning node base 10;One end of tensioning cable 41 is connected with tensioning jack 31 after passing through tensioning node base 10, and tensioning cable 41 is mainly used to pull the horizontal direction of the steel truss to be rectified A.

[0025] When being used specifically, force transmission structure, such as vertical jacks, is arranged between the middle of tensioning cable 41 and the structure in the horizontal direction of the steel truss to be rectified A, when tensioning cable 41 is driven by tensioning jack 31, tensioning cable 41 can provide a thrust to vertical jacks in the process of tensioning, so that vertical jacks push the structure in the horizontal direction of the steel truss to be rectified A to reset in the deflection direction.

[0026] Traction cable 42 is connected with tensioning node base 10, for pulling the vertical direction of the steel truss to be rectified A. When the structure in the horizontal direction of the steel truss to be rectified A resets in the deflection direction, it will push the structure in the vertical direction of the steel truss to be rectified A to reset, and traction cable 42 pulls the structure in the vertical direction of the steel truss to be rectified A, so as to ensure the effect of the structure in the horizontal direction and the structure in the vertical direction of the steel truss to be rectified A resetting in the deflection direction.

[0027] Through the above setting, the tensioning node base 10 provides a mounting point for the tensioning jack 31, and at the same time provides a connection point for the tensioning cable 41 and the traction cable 42, which not only can adjust the direction of the traction force of the tensioning cable 41 and the traction cable 42 when the steel truss A to be corrected is corrected and pulled, but also can uniformly transmit the traction force to the structure of the steel truss A to be corrected, avoiding the direct pulling of the steel truss A to be corrected by the tensioning cable 41 and the traction cable 42, which can damage the structure of the steel truss A to be corrected, and improving the safety of the correction and pulling construction.

[0028] In specific use, the tensioning node base 10 and the tensioning jack 31 can be installed at both ends of the tensioning cable 41 according to the offset degree of the horizontal structure of the steel truss A to be corrected, forming a symmetrical structure, so that the traction force received by both ends of the tensioning cable 41 is consistent during operation, thereby improving the correction effect of the tensioning cable 41 on the horizontal structure of the steel truss A to be corrected.

[0029] The tensioning node base 10 mainly consists of a connecting back plate 11, a guide plate 12, an ear plate 13 and a mounting plate 14.

[0030] In specific application, the connecting back plate 11 is installed on the vertical column of the steel truss A to be corrected by welding by the operator. The guide plate 12 has two pieces and is connected perpendicularly to the connecting back plate 11, and the two guide plates 12 are arranged in parallel to form a guide channel on the connecting back plate 11. The mounting plate 14 is connected perpendicularly to one end of the guide channel, and the mounting plate 14 is provided with a guide through hole 141. The end of the tensioning cable 41 passes through the guide through hole 141 along the guide channel and is connected to the tensioning jack 31 mounted on the mounting plate 14. The traction cable 42 is connected to the mounting plate 14.

[0031] Through such a setting, an over-tensioning node is provided between the tensioning cable 41 and the traction cable 42 and the steel truss A to be corrected, which facilitates real-time adjustment of the traction force size and direction of the tensioning cable 41 and the traction cable 42 during traction correction operation.

[0032] In specific applications, the guide channel can be arranged obliquely along the plate surface of the connecting back plate 11, so as to adapt to the traction angle of the tensioning cable 41 and ensure that the traction force applied by the tensioning jack 31 to the tensioning cable 41 is transmitted more smoothly. The two ends of the lug plate 13 are connected with the mounting plate 14 and the traction cable 42 respectively, and the angle between the lug plate 13 and the guide channel is obtuse. This makes the traction force on the tensioning cable 41 and the traction cable 42 more uniform on the tensioning node base 10, and does not cause the to-be-corrected steel truss A to deform in a direction due to excessive traction force in the direction. At the same time, it also conforms to the actual construction, that is, the traction power source of the traction cable 42 is derived from the ground at the installation position of the to-be-corrected steel truss A, and the other end of the traction cable 42 is connected with the traction equipment, so that the traction force of the traction cable 42 is transmitted more smoothly.

[0033] The lug plate 13 is provided with a connecting hole 131 for connecting the traction cable 42, so as to facilitate the disassembly and assembly of the traction cable 42 by the operator.

[0034] The threaded sleeve 21 is sleeved on the end of the tensioning cable 41, the threaded sleeve 21 passes through the guide through hole 141 and is clamped with the limiting plate 22 after the tensioning jack 31, and the threaded sleeve 21 and the tensioning cable 41 are connected by Babbitt alloy pouring. Such a setting mode makes the connection between the tensioning cable 41 and the tensioning jack 31 more stable, and improves the safety of the traction correction construction.

[0035] The limiting plate 22 is provided with a threaded hole, and the limiting plate 22 and the threaded sleeve 21 form a threaded connection, so as to facilitate disassembly and assembly during actual operation.

[0036] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
