[0042] In order to describe the steel tie rod installation device of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1 The schematic principle of the steel tie rod installation device according to an embodiment of the present invention is shown; Figures 2 to 5 The schematic structures of the steel tie rod installation device and its components according to the embodiments of the present invention are shown from different angles.

[0044] like Figures 1 to 5 As shown together, the steel tie rod installation device of the embodiment of the present invention includes a slot bracket 3-1 and a movable adjustment bracket 3-4 arranged on the slot bracket 3-1; wherein, an adjustment hole is arranged on the slot bracket 3-1, and the movable adjustment bracket 3-4 is movable and limited to move in the adjustment hole by a limiting round steel 3-4-3 and a limiting bolt 3-3, and in addition, an arc-shaped limiting member 3-4-4 is arranged on the limiting round steel 3-4-3, and the slot bracket 3-1 is limited as a whole on the steel beam to be installed with the steel tie rod, and a steel tie rod installation device 301 is arranged on the steel beam 11 A steel tie rod installation device 302 is arranged on the steel beam 12, and one end of the steel tie rod 2 is limited in the arc-shaped limit piece 3-4-4, wherein the movable adjustment bracket 3-4 can move vertically in the adjustment hole, and is used for longitudinal adjustment of the steel tie rod 2. The limiting round steel 3-4-3 is moved laterally in the adjustment hole through the limiting bolt 3-3, and is used for transverse adjustment of the steel tie rod 2. Then, through the cooperation of the movable adjustment bracket 3-4 and the groove bracket 3-1, the positioning and adjustment of the steel tie rod 2 are realized, and the installation and disassembly are convenient, and the device is reusable.

[0045] Among them, the slot-type bracket 3-1 includes two symmetrically distributed side frames 3-1-1, two limit frames 3-1-2 arranged parallel to the two side frames 3-1-1, and a connecting frame 3-1-4 arranged between the side frames 3-1-1 and the limit frames 3-1-2 on the corresponding sides. Adjustment holes are respectively arranged on the two limit frames 3-1-2. The entire slot-type bracket 3-1 presents a symmetrical frame structure. During application, the steel beam is limited on the side frames 3-1-1 and the limit frames 3-1-2, so that the connecting frame 3-1-4 is hung on the upper surface of the steel beam, and then the entire device is locked and fixed, so as to assist the installation of the steel tie rod 2.

[0046] Specifically, the movable adjustment bracket 3-4 includes two slide rail clamps 3-4-1 arranged on the outside of the two limit frames 3-1-2, and a slot hole is arranged on the slide rail clamp 3-4-1, and the position of the slot hole corresponds to the adjustment hole. After the limiting round steel 3-4-3 passes through the slot hole and the adjustment hole, the two ends are adjusted and locked by the limiting bolts 3-3 to movably limit the slide rail clamp 3-4-1 on the slot bracket 3-1. After loosening the limiting bolts 3-3, the position of the limiting round steel 3-4-3 in the adjustment hole can be adjusted, only to realize the position adjustment of the arc-shaped limiting member 3-4-4, and then the position is locked by the limiting bolts 3-3.

[0048] Among them, in order to ensure the adjustment accuracy of the slide rail card plate 3-4-1, a through hole can be set on the connecting frame 3-1-4, and the slide rail card plate 3-4-1 passes through the through hole to limit, so as to play the role of a sliding track. It can be seen that in addition to setting the limiting method of the through hole, a slide rail or other limiting methods can also be set; in addition, an extended extension plate and a precision adjustment screw 3-5-1 passing through the two extension plates are provided on the connecting frame 3-1-4, and the precision adjustment screw 3-5-1 passes through and is limited at the two An extension plate is provided on the fine-adjusting screw 3-5-1. In addition, a fine-adjusting gear 3-5-2 is provided on the slide rail clamp 3-4-1. Teeth meshing with the fine-adjusting gear 3-5-2 are provided on the slide rail clamp 3-4-1.

The fine-adjusting screw 3-5-1 and the fine-adjusting gear 3-5-2 can constitute an adjustment component 3-5.

[0049] It can be seen that in order to facilitate the adjustment of the fine adjustment screw 3-5-1, an operating handle 3-5-3 can be set at one end or both ends of the fine adjustment screw 3-5-1. The operating handle 3-5-3 can be a spherical structure as shown in the figure, and can also be set to various structures such as an elliptical or cylindrical shape. The operating handle 3-5-3 is convenient for the installer to adjust the rotation of the fine adjustment screw 3-5-1.

[0050] In a specific embodiment of the present invention, fastening bolts are respectively provided between the two side frames 3-1-1, between the two limit frames 3-1-2, and between the side frame 3-1-1 and the limit frame 3-1-2 on the corresponding side, including fastening bolts 3-1-3 and fastening bolts 3-2. After the slot-type bracket 3-1 is hung on the steel beam, the entire device can be locked and limited on the steel beam by locking and fixing it with the locking bolts.

[0051] In addition, the arc-shaped limit member 3-4-4 can be an arc-shaped groove structure welded and fixed on the limiting round steel 3-4-3.
