[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The inverted triangle truss is a truss structure with an inverted triangle cross section. It is widely used in steel structures. Due to the long length and high installation height of the inverted triangle truss, the inverted triangle truss is usually assembled on the ground frame and then hoisted to the installation location as a whole by hoisting equipment.

[0003] At present, most inverted triangle trusses are assembled on a frame. Due to different construction facilities, the sizes of the inverted triangle trusses used are also different.

[0032] Combination Figure 1 , Figure 3 and Figure 4The embodiment of the present application discloses an inverted triangular secondary truss assembly frame for a roof, including a longitudinal frame 1, the number of which is two, a row of threaded holes is provided on the top of the longitudinal frame 1, two symmetrical cross beams 2 are fixedly installed on the top of the longitudinal frame 1 by bolts, a vertical rod 3 is welded on the top of the cross beam 2, a longitudinal reinforcing plate 4 is welded on the inner cavity of the vertical rod 3, a sliding sleeve 5 is slidably connected to the surface of the vertical rod 3, two symmetrical limit strips are welded on the front and back of the sliding sleeve 5, the left side of the slide 9 is in contact with the limit strip, and the two The opposite side of the sliding sleeve 5 is welded with a supporting cross frame 6, and the left side of the supporting cross frame 6 is penetrated by a threaded rod 15, which penetrates into the inner cavity of the supporting cross frame 6 and is rotatably connected to the supporting cross frame 6. The inner cavity of the supporting cross frame 6 is slidably connected to a limited block 16, and the threaded rod 15 is threadedly connected to the limited block 16. By cooperating with the threaded rod 15 and the limited block 16, the position of the limited block 16 can be adjusted by rotating the torsion block 18, so that the limited block 16 fits on the surface of the inverted triangular secondary truss, and a certain limit is imposed on it to prevent the inverted triangular secondary truss from sliding on the top of the supporting cross frame 6, thereby increasing the stability of the inverted triangular secondary truss during assembly. Two symmetrical sliding grooves 17 are provided on the top of the supporting cross frame 6, and the limited block 16 passes through the sliding groove 17 to the outside of the supporting cross frame 6. A torsion block 18 is welded on the left side of the threaded rod 15, and two symmetrical torsion bars are welded on the surface of the torsion block 18. Two symmetrical fixed blocks 7 are welded on the surface of the sliding sleeve 5, and two symmetrical sliding rods 8 are welded on the front and back sides of the sliding sleeve 5. A slide 9 is sleeved on the surface of the slide sleeve 5, and grooves 10 are provided on the front and back of the slide 9. The fixed block 7 is in the inner cavity of the groove 10. The slide 9 is slidably connected with the slide rod 8. A spring 11 is sleeved on the surface of the slide rod 8. One end of the spring 11 is welded to the slide 9, and the other end of the spring 11 is welded to the fixed block 7. A row of limiting holes 12 are provided on the surfaces of the vertical rod 3, the reinforcing plate 4 and the slide sleeve 5. Three symmetrical limiting rods 13 are welded on the left side of the slide 9, and the limiting holes 12 are adapted to the limiting rods 13. Example

[0033] Combination Figure 2 and Figure 3 The left side of the slide 9 is rotatably connected with a pull ring 14, and a supporting diagonal rod is welded at the bottom of the supporting cross frame 6, and the supporting diagonal rod is welded to the left side of the sliding sleeve 5. Through the setting of the pull ring 14, the user pulls the pull ring 14 to make the slide 9 move, avoiding the user from directly pushing the slide 9 to slide, and facilitating the user to adjust the position of the sliding sleeve 5, thereby increasing the convenience of adjusting the position of the supporting cross frame 6.

When the supporting cross frame 6 reaches a suitable position, the pull ring 14 is released to stretch the spring 11, so that the spring 11 will push the slide 9 to the supporting cross frame 6. The support cross frame 6 slides in the direction of the frame 6, so that the limiting rod 13 enters the inner cavity of the limiting hole 12, limits the sliding sleeve 5, and fixes the supporting cross frame 6 in a suitable position, so that the supporting cross frame 6 can support the inverted triangular secondary trusses of different sizes. By using the threaded rod 15 and the limiting block 16 in coordination, the torsion block 18 can be rotated to adjust the position of the limiting block 16, so that the limiting block 16 fits on the surface of the inverted triangular secondary truss, limits it to a certain extent, and prevents the inverted triangular secondary truss from sliding on the top of the supporting cross frame 6, thereby increasing the stability of the inverted triangular secondary truss during assembly.

[0035] To sum up: the inverted triangular secondary truss of the roof is assembled by fixing the crossbeam 2 at a suitable position on the top of the longitudinal frame 1 by bolts, and pulling the pull ring 14 to slide the slide 9 in the direction away from the supporting cross frame 6, so that the limiting rod 13 is separated from the inner cavity of the limiting hole 12, and then the slide 9 squeezes the spring 11 to shrink the spring 11, and the sliding sleeve 5 can be adjusted to the position of the supporting cross frame 6 to a suitable height, and the pull ring 14 is released, the spring 11 will stretch, and the limiting rod 13 will enter the inner cavity of the limiting hole 12 to limit the sliding sleeve 5, thereby avoiding that the assembly frame cannot be applied to inverted triangular secondary trusses of different sizes, thereby increasing the applicability of the assembly frame.
