Description

Technical Field

[0001] The invention relates to the field of electrical installation, and in particular to a HALFEN trough support arm adjustment method. Background Art

[0002] In installation projects, especially in integrated pipe corridors and cable tunnels, in order to improve the efficiency of electrical bridge construction and reduce costs, most of them use pre-buried HALFEN Troughs, which mainly play the role of support and fixation. In electrical installation, the bracket arm can firmly fix the cable bridge on the HALFEN Trough to ensure that the bridge will not sag and deform due to its own weight or the weight of the cable, and ensure the safe and neat laying of the cable. At the same time, this bracket arm is easy to install and can effectively improve the efficiency and flexibility of electrical installation. During the adjustment process of the HALFEN Trough bracket arm, due to deviations in the pre-buried process or bending of the HALFEN Trough body (also within the allowable deviation range), these deviations cause the bracket arms between different layers to be non-vertical during the installation of the bracket arm, or the bracket arms on the same layer to be non-horizontal. In order to ensure the construction quality, most of them use inclined pads between the bracket arm and the HALFEN Trough for adjustment. This method can solve the above problems, but the adjustment process is extremely cumbersome. The addition of inclined pads causes the visual quality of the connection between the bracket arm and the HALFEN Trough to be poor, and increases the construction cost. Summary of the invention

An adjusting bolt 6 is installed in the inner thread of the thread 5, and the adjusting bolt 6 can be screwed to the side of the fixing plate 3 away from the bracket 2.

[0021] In the above steps, a thread 5 is respectively provided at the four corners of the fixing plate 3, and an adjusting bolt 6 is threadedly installed in each thread 5. The thread 5 is provided in the opening of the fixing plate 3. The axis of the thread 5 is perpendicular to the fixing plate 3. The axial length of the thread 5 is equal to the thickness of the fixing plate 3. The adjusting bolt 6 has a screw rod and a bolt head. The axial length of the screw rod is equal to the axial length of the thread 5. The radial width of the bolt head is greater than the radial width of the screw rod. There are multiple bracket arms 2, and each bracket arm 2 is provided with a thread 5 and an adjusting bolt 6.

[0022] (2) Preliminarily tighten the T-bolts 4 that fix the bracket arm 2 and the Halfen trough 1, that is, tighten them slightly to fix the bracket arm 2 on the Halfen trough 1.

[0023] In the above steps, there are multiple Halfen slots 1, and multiple bracket arms 2 are fixed on one Halfen slot 1. There are multiple T-bolts 4, and two upper and lower T-bolts 4 fix one bracket arm 2 on the Halfen slot 1.

[0024] (3) Adjust the horizontality of the supporting arms 2 which are arranged on different Halfen troughs 1 and on the same layer.

[0025] In the above steps, a laser level or a pre-set horizontal line is used to adjust the level of the supporting arm 2 arranged on the same layer.

[0026] When the support arm 2 tilts upward, the adjusting bolt on the upper side of the support arm 2 is screwed, and the adjusting bolt is pushed toward the outer wall of the Halfen trough 1 to adjust the support arm 2 to a horizontal position. When the support arm 2 falls downward, the adjusting bolt on the lower side of the support arm 2 is screwed, and the adjusting bolt is pushed toward the outer wall of the Halfen trough 1 to adjust the support arm 2 to a horizontal position.

[0027] (4) Correct the overall verticality of the supporting arms 2 arranged on the same Halfen trough 1 and arranged on different layers.

[0028] In the above steps, a plumb line is used to calibrate the overall verticality of the support arm 2 arranged on the same Halfen trough 1 .

[0029] When the support arm 2 tilts to the right, screw the adjustment bolt on the right side of the support arm 2, push the adjustment bolt toward the outer wall of the Halfen Trough 1, and adjust the support arm 2 to be vertical. When the support arm 2 tilts to the left, screw the adjustment bolt on the left side of the support arm 2, push the adjustment bolt toward the outer wall of the Halfen Trough 1, and adjust the support arm 2 to be vertical.
