Description

Technical Field

[0001] This utility model relates to the field of roof purlin tie rod technology, and in particular to a tie rod assembly for roof purlins. Background Technology

[0002] Roof purlins and tie rods are important auxiliary components in roof structures. These tie rods enhance the stability of the roof structure, enabling it to better resist external forces such as wind loads and seismic forces. To ensure the effectiveness of the tie rods, a tensioning device for roof purlins in light steel mills, disclosed in CN222796886U, is described. For horizontal connection of the tie rods, one end is inserted into the mounting housing through the mounting groove, and then a bolt is connected to the threaded hole on the surface of the mounting housing. This achieves the purpose of installing the tie rod. However, for inclined installation of the tie rods, the mounting housing is first rotated to adjust it to the same angle as the inclined tie rod. Then, the extension connecting plate is pulled to one side. This causes the connecting rod connected to one side of the extension connecting plate to slide in the slide rail of the limiting plate, allowing the extension connecting plate to be pulled out to one side, so that one end of the tie rod is inserted into the through groove of the extension connecting plate.

[0003] However, in the existing technology, when the through groove size is fixed, it is easy to have an excessive gap between the tie rod and the inner wall of the through groove when using tie rods of different sizes. Due to the excessive gap, the bolt needs to withstand more shear and tensile forces, and these forces are concentrated in the local area where the bolt contacts the tie rod. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4As shown, a tie rod assembly for roof purlins includes a tie rod 1. Both ends of the tie rod 1 are provided with traction heads 2 for connecting to purlins. The traction head 2 includes an upper clamping piece 3 for connecting to the upper surface of the purlin and a lower clamping piece 16 for conforming to the lower surface of the purlin. The purlin is clamped vertically by the relative movement of the upper clamping piece 3 and the lower clamping piece 16. Upper clamping blocks 4 are inserted into both sides of the upper clamping piece 3, clamping the upper side of the purlin using the two upper clamping blocks 4. A lower clamping block 7 is provided below each upper clamping block 4, inserting into the side of the lower clamping piece 16, clamping the bottom side of the purlin using the two lower clamping blocks 7. Different sizes of purlin ends can be clamped by the relative movement of the two upper clamping blocks 4 or the two lower clamping blocks 7. At least two screws are provided through each of the upper clamping piece 3 and the lower clamping piece 16 on opposite sides. Bolt 12; The bolt 12 in the upper clamping plate 3 passes through the two upper clamping blocks 4 and is threadedly connected to the upper surface of the purlin. The bolt 12 in the lower clamping plate 16 passes through the two lower clamping blocks 7 and is threadedly connected to the lower surface of the purlin. This allows the upper clamping plate 3 to be fixed in relative position with the two upper clamping blocks 4, or the lower clamping plate 16 to be fixed in relative position with the two lower clamping blocks 7. The upper clamping blocks 4 and lower clamping blocks 7 on the same side of the upper clamping plate 3 are used to fit against the side of the purlin. A stud 5 is provided between the upper clamping blocks 4 and lower clamping blocks 7 on the same side of the upper clamping plate 3. By connecting the upper clamping blocks 4 and lower clamping blocks 7 on the same side through the stud 5, a traction force can be applied to the upper clamping blocks 4 and lower clamping blocks 7 in the same direction on the side of the purlin, so that the upper clamping blocks 4 and lower clamping blocks 7 move relative to each other to clamp the side of the purlin.

[0023] The upper clamping plate 3 and the lower clamping plate 16 extend outwards on one side, and several long screws 13 are provided through the extension. The length of the long screws 13 is selected according to the thickness of the purlin. By using the long screws 13 to pass through the extension of the upper clamping plate 3 and the lower clamping plate 16, and by setting nuts on the long screws 13, the nuts can move on the long screws 13, pushing the upper clamping plate 3 and the lower clamping plate 16 to move relative to each other and clamp the purlin along the thickness direction. A connecting block 14 is provided between the upper clamping plate 3 and the lower clamping plate 16, which is inserted into the several long screws 13. One side of the connecting block 14 is rotatably connected to a disc 8 for fixing to the purlin surface, and the other side of the connecting block 14 is inserted into a plug 15 for clamping the several long screws 13. The plug 15 and the connecting block 14 are connected by bolts, thus facilitating the fixing of the plug 15 and the connecting block 14 to the several long screws 13, and further... By connecting the disc 8 to the purlin surface with bolts, the tilt of the traction head 2 can be adjusted by rotating the connecting block 14 and the disc 8. This is suitable for inclined pull bars 1. The edge of the disc 8 end face has several insertion holes 11 arranged in a ring array about the central axis of the disc 8. A bracket 9 is inserted into the surface of the connecting block 14. A spring rod 10 is provided between one side of the bracket 9 and the connecting block 14, and the other side of the bracket 9 extends outward to form several protrusions for passing through the insertion holes 11. By moving the bracket 9 to overcome the pushing force of the spring rod 10, it moves to the insertion hole 11 that is detached from the surface of the disc 8, so that the connecting block 14 can rotate relative to the disc 8. After the rotation is completed, the bracket 9 is released and pushed by the spring rod 10, so that the bracket 9 is re-inserted into the corresponding insertion hole 11 on the surface of the disc 8, thus fixing the relative position of the connecting block 14 and the disc 8.

[0024] The two upper locking blocks 4 and the upper clamping piece 3 are staggered vertically, and the two lower locking blocks 7 and the lower clamping piece 16 are also staggered vertically, ensuring that the two upper locking blocks 4 or the two lower locking blocks 7 can move relative to each other.

[0025] One end of the stud 5 is threaded through the surface of the lower clamping block 7, and the other end of the stud 5 is threaded through the side of the upper clamping block 4. The upper clamping block 4 and the lower clamping block 7 are parallel to the upper surface of the upper clamping plate 3 and have a hollowed-out shape, which is used to connect with the bolt 12. The surface of the upper clamping block 4 is rotatably connected to a detachable nut 6 that is threadedly connected to the stud 5. In use, first rotate the stud 5 to install the stud 5 in the lower clamping block 7, then align the nut 6 on the surface of the upper clamping block 4 with the stud 5, and rotate the nut 6 to drive the stud 5 to move the lower clamping block 7 up and down, so that the upper clamping block 4 and the lower clamping block 7 on the same side can move relative to each other.

[0026] Working principle: During use, the disc 8 is fixedly installed on the surface of the purlin, and the inclination of the connecting block 14 is adjusted according to the installation direction of the purlin. The upper clamping plate 3 and the lower clamping plate 16 are installed on both sides of the connecting block 14, and the upper clamping plate 3 and the lower clamping plate 16 are connected by a long screw 13 through the connecting block 14. The long screw 13 is used to clamp the purlin with the upper clamping plate 3 and the lower clamping plate 16. Then, two upper clamping blocks 4 are installed on the upper clamping plate 3, and two lower clamping blocks are installed on the lower clamping plate 16. 7. Use bolts 12 to fix the relative positions of the upper clamping piece 3, the two upper clamping blocks 4 and the top edge of the purlin, or use bolts 12 to fix the relative positions of the lower clamping piece 16, the two lower clamping blocks 7 and the bottom edge of the purlin. Use the two upper clamping blocks 4 to clamp the upper side of the purlin and the two lower clamping blocks 7 to clamp the bottom side of the purlin. Then install studs 5 and use studs 5 to tighten the upper clamping blocks 4 and lower clamping blocks 7 on the same side to fix the end of the tie rod 1.
