Description

Technical Field

[0001] The present invention relates to the technical field of pre-buried channel positioning, and more specifically, to a pre-buried channel positioning device and a construction method. Background Art

[0002] Embedded channel is a metal channel or trough pre-installed in concrete during the construction of building structures, used as a support structure for the subsequent installation of various facilities. It is widely used in infrastructure projects such as railways, urban rail transit, bridges, tunnels, etc., especially in the fixing and support of electrified railway contact network systems and urban rail transit power supply systems.

[0003] To ensure that the spacing between multiple channels meets the design requirements, it is usually necessary to weld connecting flat steel between the channels, and the connection between the flat steel and the channels is fully welded. In addition, the flat steel can significantly increase the overall rigidity of the structure and reduce the deformation or displacement of the channels caused by external loads; and welding flat steel helps to better disperse the stress applied to the channels and avoid damage caused by local stress concentration.

[0004] If the flat steel is welded to the channel in the factory, it is easy for the flat steel to bend and deform when the channel is transported to the construction site by truck, which may cause a deviation in the distance between the two channel. If the flat steel is welded at the construction site, the two channel are usually positioned manually before welding. The position of the two channel is difficult to control before and after welding, and the two channel are prone to offset, which in turn causes a deviation in the welding distance, greatly affecting the installation of the channel and the fixation and support of subsequent facilities.

[0005] Therefore, it is necessary to provide a positioning device and construction method for a pre-buried groove to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a positioning device and a construction method for a pre-buried channel to solve the above technical problems.

[0019] Furthermore, a vertical plate is provided on the limiting seat, and an upper pressing block with an adjustable height is provided on the vertical plate for closely contacting the upper end surface of the groove.

[0020] Furthermore, an adjustment hole is provided on the vertical plate, a stud connected to the upper pressing block is movably provided in the adjustment hole, and a fastening nut is threadedly connected to the stud.

[0021] Furthermore, rubber pads are detachably mounted on the bottom of the upper pressing block and the sides of the side pressing blocks.

[0022] Furthermore, a scale bar is provided on the side wall of the positioning seat, and a pointer corresponding to the scale bar is provided on the side wall of the positioning seat.

[0041] See also Figure 1-5 A positioning device for a pre-buried channel is used to position the channel 1 and weld the flat steel 2 to the channel 1, comprising:

[0042] A support frame 3 is provided with a plurality of positioning seats 4, and two symmetrical limiting seats 5 are provided on the positioning seats 4;

[0043] The adjusting mechanism 6 is arranged on the positioning seat 4 and is used to drive the two limiting seats 5 to move synchronously and in opposite directions;

[0044] A side pressure block 7 is slidably disposed on the limiting seat 5 and is used to be close to the side wall of the channel 1;

[0045] The clamping mechanism 8 is arranged on the limiting seat 5 and is used to drive the side pressure block 7 to move horizontally.

[0046] When in use, this positioning device is placed at the corresponding position on the construction site, and the two grooves 1 to be welded are placed on the positioning seats 4 of the support frame 3, that is, the two grooves 1 are respectively placed on the two limit seats 5 of the positioning seats 4, and the two grooves 1 are adjusted to correspond to each other front and back, and then the side pressure blocks 7 are driven by the clamping mechanism 8 to move horizontally left and right, so that the side pressure blocks 7 move toward the direction of the side walls of the grooves 1, and finally the side pressure blocks 7 are pressed against the side walls of the grooves 1, and the grooves 1 are pressed by the side pressure blocks 7, that is, the grooves 1 are positioned and fixed, so that the two grooves 1 remain stable. At this time, the distance between the two grooves 1 is constant, and then the flat steel 2 can be welded to the two grooves 1, that is, the two grooves 1 can be connected. At this time, the offset between the two grooves 1 during welding can be avoided, and the deviation of the spacing between the two grooves 1 can be prevented. The welding effect of the flat steel 2 and the groove 1 is good, which greatly improves the quality of the two grooves 1 after welding, reduces the generation of welding errors, and can effectively ensure the subsequent installation of the groove 1 and the effect of facility fixation. Moreover, the welding process can be completed by one person, which reduces manpower input and improves the stability during welding. The operation is simpler and more convenient, which significantly improves the construction efficiency. It has high practicality and can be promoted for use.

[0047] Before placing the groove 1, the two limit seats 5 can be driven to move closer to or away from each other through the adjustment mechanism 6, so the distance between the two limit seats 5 can be adjusted. The groove 1 is placed on the limit seats 5, so the spacing between the two grooves 1 can be adjusted by adjusting the distance between the two limit seats 5, and then the position of the limit seat 5 can be adjusted according to the welding requirements of the grooves 1 with different spacings, which can meet the use of various situations, has a wide range of applications and strong flexibility.

[0050] The limiting rod 62 is disposed on the positioning seat 4 , and the limiting rod 62 slidably passes through the two positioning seats 4 .

[0051] Specifically, when the rotating shaft 61 is rotated, the positioning seat 4 will not rotate due to the restriction of the limiting rod 62. At this time, the rotation of the rotating shaft 61 will drive the limiting seat 5 to move in the left and right directions, and since the threads on both sides of the rotating shaft 61 have opposite rotation directions, the movement directions of the two limiting seats 5 are opposite, that is, the distance between the two limiting seats 5 will gradually become longer or shorter, and the limiting seat 5 will move along the limiting rod 62, and the position of the limiting seat 5 can be adjusted as needed.

[0052] In this embodiment, preferably, please refer to Figure 2-5, the clamping mechanism 8 comprises:

[0053] The screw rod 81 is threadedly connected to the limiting seat 5 , one end of the screw rod 81 is rotatably connected to the side pressure block 7 , and the other end is provided with a rotating cap 82 .

[0054] Specifically, after the channel 1 is placed on the limiting seat 5, the rotating cap 82 is rotated, the rotating cap 82 will drive the screw 81 to rotate, and the screw 81 will also move left and right while rotating. Since the screw 81 and the side pressure block 7 are rotatably connected, the other end of the screw 81 will drive the side pressure block 7 to move left and right along the limiting seat 5, so that the side pressure block 7 can move closer to or away from the side wall of the channel 1, that is, the channel 1 can be tightly pressed and fixed.

[0055] In this embodiment, preferably, please refer to Figure 3-5 The limit seat 5 is provided with a slide groove 9, in which a slider 10 is slidably arranged, and the upper end of the slider 10 is connected to the side pressure block 7.

After the adjustment is completed, the fastening nut 15 is tightened, and the stud 14 and the upper pressing block 12 are fixed at the adjusted height position through cooperation with the vertical plate 11, and can be adjusted according to specific needs, with good use effect.

[0058] In this embodiment, preferably, please refer to Figure 3-5The bottom of the upper pressing block 12 and the side of the side pressing block 7 are detachably provided with rubber pads 16. With this design, when the upper pressing block 12 and the side pressing block 7 are in close contact with the channel 1, the rubber pads 16 can protect the channel 1, reduce hard contact, effectively reduce the extrusion damage to the channel 1, and have a good protective effect.

[0059] In this embodiment, preferably, please refer to Figure 1-3 , a scale bar 17 is provided on the side wall of the positioning seat 4, and a pointer 18 corresponding to the scale bar 17 is provided on the side wall of the positioning seat 4.
