Description

Technical Field

[0001] The invention relates to the field of steel structure connectors, and in particular to an arc-shaped steel structure atrium connection component with unequal height and unequal span and a construction method thereof. Background Art

[0002] Sliding construction of steel structures is to move the steel structures to the assembly position by sliding. Figure 7 As shown, the atrium roof needs to be equipped with multiple steel beams of different spans. The curved trajectory of the atrium increases the difficulty of assembling the steel beams. The formed buildings around the atrium affect the assembly construction of the steel beams. In this case, it is more appropriate to use the sliding construction method for the atrium roof steel beams. The steel beams are lifted one by one from both sides and moved to the assembly position one by one with the sliding facilities.

[0003] Since the two sides of the atrium roof are not at the same height, the assembly height error of the steel beams at both ends needs to be controlled within an appropriate range. Traditionally, the assembly height of the steel beams is controlled by setting pads. However, the atrium steel beams have a large span and weight, and there is a high risk of roof slippage. The traditional method of controlling and adjusting the assembly height of the steel beams is slow and has a high construction risk. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide an unequal height and unequal span arc-shaped steel structure atrium connection component and a construction method thereof, so as to solve the problem of slow assembly efficiency and high risk of unequal height steel beams of atrium roof.

[0013] Preferably, the top surface of the support has upwardly protruding edges on both sides, and gaps for limiting the roof steel beams are formed between the edges. The top surface of the support has a V-shaped groove, which is perpendicular to the limiting direction of the edges, and the bottom of the roof steel beam has a V-shaped block that fits the V-shaped groove.

[0014] A steel structure assembly construction method based on the unequal height and unequal span arc-shaped steel structure atrium connection assembly comprises the following steps:

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The steel structure connection assembly is designed for the rapid height adjustment assembly of the atrium roof steel beams 8 with large spans and unequal heights. There is a height difference between the two sides of the atrium roof area 9, and one side of the atrium roof area 9 is an arc-shaped profile. The roof steel beams 8 to be built are adapted to the different spans of the arc-shaped profiles of the atrium roof area 9. A plurality of sets of relatively positioned L-shaped supports 5 are arranged at the edge of the atrium roof area 9 for carrying and assembling the roof steel beams 8, and a set of steel structure connection assemblies is arranged at each L-shaped support 5.

[0033] like Figure 1 , Figure 2 As shown, the steel structure connection assembly is mainly composed of an inclined pad 1, an inclined slider 2, and a support 3. The horizontal bottom surface of the L-shaped support 5 has four vertically extending embedded screws 51, the surfaces of the inclined pad 1 and the support 3 have through holes for the embedded screws 51, and the surface of the inclined slider 2 has strip holes 21 for the embedded screws 51.

[0034] Before assembling the roof steel beam 8, the inclined pad 1, the inclined slider 2, and the support platform 3 are stacked and placed on the horizontal bottom surface of the L-shaped support 5 in sequence, and the embedded screw 51 penetrates the through holes and the strip holes 21 of the inclined pad 1, the inclined slider 2, and the support platform 3 upward. The embedded screw 51 penetrates the strip holes 21 to limit the position of the inclined slider 2 relative to the inclined pad 1 and the support platform 3 on both sides, so that the inclined slider 2 can slide linearly relative to the inclined pad 1 and the support platform 3. The flat surface of the inclined pad 1 and the inclined slider 2 is an inclined surface, and the inclined slider 2 and the support platform 3 are horizontally flat. The inclined slider 2 slides along the inclined pad 1 to adjust the height of the support platform 3;

[0035] The end of the roof steel beam 8 is pressed flat on the surface of the support platform 3, and the embedded screw 51 is passed through the nail hole on the edge of the roof steel beam 8 upward, so that the horizontal position of the end of the roof steel beam 8 is positioned, and two long tie rods 52 are passed through and fixed on the vertical surface of the L-shaped support 5. The long tie rods 52 pass through the strip-shaped through holes on the end surface of the roof steel beam 8. There are clamping parts 4 on both sides of the inclined slider 2. The long tie rods 52 pass through the clamping parts 4 and are limited by nuts to the clamping parts 4;

[0036] By rotating the nut of the limit clamp 4 on the surface of the long pull rod 52, the nut pushes the clamp 4 to drive the inclined slider 2 to move relative to the inclined pad 1 and the support 3, which is used to adjust the height of the end of the roof steel beam 8 supported by the support 3. After the height of the end of the roof steel beam 8 is marked, tighten another set of nuts on the surface of the long pull rod 52 that are aligned with the end face of the roof steel beam 8 to lock the roof steel beam 8 and the long pull rod 52, and then use the nut to combine with the embedded screw 51 to tighten and fix the roof steel beam 8, the support 3, the inclined pad 1 and the bottom surface of the L-shaped support 5 in the vertical direction to complete the assembly and fixation of the roof steel beam 8.

[0037] like Figure 1 , Figure 2 As shown, a short tie rod 53 is provided through the side of the L-shaped support 5, and the short tie rod 53 is connected to the end surface of the roof steel beam 8 to improve the stability of the lateral pulling and fixing of the roof steel beam 8.

[0038] like Figure 3 As shown, the clamping member 4 includes a fastener 41, which is fixed to the side of the inclined slider 2 by two screws. The top of the fastener 41 has a U-shaped rod groove 42, and a long pull rod 52 passes through the rod groove 42. The surface of the long pull rod 52 has nuts that abut against both sides of the rod groove 42. By rotating the nut, the fastener 41 is pushed to drive the inclined slider 2 to move, thereby realizing the height adjustment of the end of the roof steel beam 8.

[0039] like Figure 4 As shown, guide grooves 22 parallel to the support platform 3 and the inclined pad 1 are respectively provided on the top and bottom surfaces of the inclined slider 2, and a guide block 6 is fixed on the surface of the support platform 3 and the inclined pad 1. The guide block 6 slides to fit the guide groove 22 to improve the stability of the inclined slider 2 moving relative to the inclined pad 1 and the support platform 3.

[0040] Since the inclined slider 2 is in contact with the inclined pad 1, after the height of the end of the roof steel beam 8 is adjusted, the inclined pad 1, the inclined slider 2 and the support 3 need to be locked to improve the stability of the support for the roof steel beam 8. The specific operation is as follows:

[0041] like Figure 3As shown, a rack 46 parallel to the inclined plane slider 2 is fixed on the side of the inclined plane pad 1 and the support platform 3, and the surface of the fastener 41 has an embedding groove 43, and the U-shaped card plate 44 can be inserted into the embedding groove 43. Both ends of the U-shaped card plate 44 have tooth surfaces aligned with the rack 46. A stud 45 is used to penetrate the U-shaped card plate 44, the fastener 41 and the inclined plane slider 2 to be threadedly connected, and the U-shaped card plate 44 is fixed in the embedding groove 43. At this time, the tooth surfaces at both ends of the U-shaped card plate 44 are engaged with the rack 46 to lock the position between the inclined plane pad 1, the inclined plane slider 2 and the support platform 3;

[0042] like Figure 4 , Figure 5 As shown, two tooth plates 7 are symmetrically and elastically rotatably installed inside the inclined slider 2, and the tooth plates 7 can be inserted into the guide groove 22. The surface of the guide block 6 has a toothed portion, and the close surfaces of the two tooth plates 7 have a wedge block 71. The end of the stud 45 is conical. When the stud 45 is tightened to fix the U-shaped clamping plate 44, the conical end of the stud 45 presses inward between the wedge blocks 71, so that the two tooth plates 7 expand and move to engage with the toothed portion on the surface of the guide block 6, further improving the locking strength of the inclined pad 1, the inclined slider 2, and the support 3.

[0043] like Figure 3 , Figure 6 As shown, both sides of the top surface of the support platform 3 have upwardly protruding edges 31, and a gap for limiting the roof steel beam 8 is formed between the edges 31. The roof steel beam 8 is dropped onto the top surface of the support platform 3, and the positions of both sides of the roof steel beam 8 are limited by the edges 31. In addition, the top surface of the support platform 3 has a V-shaped groove 32, and the V-shaped groove 32 is perpendicular to the limiting direction of the edges 31. The bottom of the roof steel beam 8 has a V-shaped block 81 that fits the V-shaped groove 32. The V-shaped block 81 is aligned with the V-shaped groove 32 to achieve rapid positioning of the roof steel beam 8 in the front and rear directions, so that the roof steel beam 8 can be quickly and stably placed on the surface of the support platform 3.

[0044] like Figure 7 As shown, the construction of the arc-shaped atrium steel structure with unequal heights and spans is completed by a sliding construction method. The roof steel beams 8 are hoisted to the top surface from both sides of the atrium roof area 9, and the roof steel beams 8 are transported to the assembly point one by one by pulling the sliding components by a winch. The roof steel beams 8 of the atrium roof area 9 are installed one by one from the middle to both sides.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
