Examples
Referring to fig. 1 and 2, an embodiment of the present invention provides a side cross arm mounting structure 100 including an iron tower body 40, a side cross arm 30 to be mounted, and at least one side cross arm fixing structure 10.
The pylon body 40 comprises a plurality of columns 41 extending vertically and distributed in a polygonal shape. The two ends of the side cross arm 30 are correspondingly connected to two adjacent upright posts 41. At least one of the upright posts 41 is an angle steel type upright post 41, and one end of the side cross arm 30 corresponding to the angle steel type upright post 41 is connected to the angle steel type upright post 41 through the side cross arm fixing structure 10. Alternatively, the pylon body 40 includes four rectangular distributed corner steel type posts 41, and the side plates 41a of the four corner steel type posts are all facing outwards. The columns 41 are connected together transversely or obliquely by connecting strips 42 to form an integral firm iron tower body 40.
In one implementation of this embodiment, the side cross arms 30 are bar-shaped angle steel, one side plate of which is attached to the outer side surfaces of the two upright posts 41 to which it is connected, and the connecting rod 11 of the corresponding side cross arm 30 of the side plate is perforated to allow the side cross arm 30 to penetrate into the connecting rod 11 and be connected to the connecting rod 11.
In order to install the side cross arm 30 on the iron tower body 40, in the prior art, two ends of the side cross arm 30 are usually installed and fixed through simple bolts and nuts respectively. To ensure that the installed side cross arm 30 is in the horizontal direction, leveling is required. The inventor researches and discovers that the time occupied by the installation of the cross arm is the largest in the construction of the upper rack of the tower, and the time occupied by the support and the leveling of the iron tower side cross arm 30 in the installation time of the cross arm of the platform area is 80% of the total time consumed by the support and the fixing of the cross arm, so that the time for the installation of the cross arm of the upper rack of the tower is shortened, and the time for the support and the leveling of the iron tower side cross arm 30 is reduced.
In this embodiment, the side cross arms 30 are connected between a set of adjacent corner steel type posts 41. The outer side surface of one side plate of one angle steel type upright post 41 is fixedly connected with a vertical extending stud M1, one end of the side cross arm 30 is provided with a hole penetrating through the stud M1 and is tightly connected with the angle steel type upright post 41 through a nut M2 connected with the stud M1 in a threaded manner. The other end of the side cross arm 30 is connected to a corresponding angle steel type column 41 through a side cross arm fixing structure 10.

The clip 12 includes two plate portions 12a opposed to each other at a distance and a connecting portion 12b connecting the corresponding sides of the two plate portions 12a, and optionally, the inner surface of the connecting portion 12b is an arc-shaped cylindrical surface. The two plate portions 12a and the connecting portion 12b are connected to form a U-shaped structure that is open in the first direction Y1 so that the clip 12 can move in the extending direction of the angle-shaped column 41 with respect to the angle-shaped column 41 in a state in which the clip 12 is vertically clipped into one side plate body of the angle-shaped column 41 in the first direction Y1. One end of the connecting rod 11 is connected to the clamping member 12, and the other end extends out along the first direction Y1 for connecting the side cross arm 30. In one implementation of this embodiment, clip 12 is a flat iron bent into a U-shape. In one implementation of the present embodiment, the connecting rod 11 is welded to the outer side surface of one of the plate portions 12a, so that the clip 12 and the connecting rod 11 are integrally connected.
The side cross arm fixing structure 10 in this embodiment is used to fix the side cross arm 30 to the side of the pylon. Specifically, one end of the side cross arm 30 is fixed by the side cross arm fixing structure 10 and a vertical column 41 of an angle steel type on the side of the iron tower in a matched limiting manner, and the other end of the side cross arm 30 can be connected to the other vertical column 41 on the side of the iron tower in a matched limiting manner by the side cross arm fixing structure 10 or other structures such as simple bolt connection.
The cooperation connection of the side cross arm 30 through the side cross arm fixing structure 10 and the angle steel type upright 41 may be: the clamping piece 12 is clamped into one side plate body of the angle steel type upright 41 to the outer edge of the side plate body to form line fit along the inner surface of the joint contact connection part 12b, and the height of the clamping piece 12 can be adjusted by moving the clamping piece 12 relative to the extending direction of the angle steel type upright 41 so as to adjust the height of the connecting rod 11, so that the height of the end of the side cross arm 30 can be adjusted, the two ends of the side cross arm 30 can be ensured to be flush, and the side cross arm 30 can be conveniently adjusted to a required horizontal state.
Therefore, in this embodiment, the extending direction of the connecting rod 11 can be determined only by clamping the clamping piece 12 into one side plate body of the angle steel type upright post 41, and the height of the connecting rod 11 can be conveniently adjusted, so that the side cross arm 30 can be conveniently adjusted to a required horizontal state.
In one implementation of the present embodiment, the connecting rod 11 protrudes in the first direction Y1, so that the connecting rod 11 protrudes in the horizontal direction right after the clip 12 is snapped into place. Optionally, the outer end of the connecting rod 11 is provided with a screw of a threaded section, and the side cross arm fixing structure 10 further includes a nut M2 of a threaded mating screw. Thus, the side cross arm 30 is opened to pass through the screw rod, and then is locked and connected to the upright 41 by the nut M2.
In view of the above description, the side cross arm fixing structure 10 and the side cross arm mounting structure 100 in the embodiment of the present invention have the advantages of convenient and quick mounting and leveling of the side cross arm 30, and greatly reduced mounting time of the side cross arm 30.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
