Description

Technical Field

[0001] This utility model relates to the field of construction technology for lifting large-span space frames or trusses, and in particular to a column-top inverted triangular double-suspension-point lifting support. Background Technology

[0002] With the vigorous development of steel structures, large-span spatial steel structures are widely used in various building structures, such as airport terminals, convention centers, and stadiums. Depending on the structural characteristics and on-site construction conditions, various typical steel structure construction methods can be adopted, such as segmented hoisting, sliding, and overall lifting. Considering various factors and existing construction experience, the overall lifting method dominates. However, the lifting support, as a crucial component of the overall lifting method, not only needs to ensure overall stability and safety during the lifting process, but also needs to be easy to manufacture, save materials, and be easily reusable.

[0003] Existing lifting supports are mostly single-point lifting supports, which have problems such as simple structure, limited function, insufficient lifting stability, and low safety factor. In addition, when there are many sections in the space frame structure, the number of single-point lifting supports will also increase, which will increase material and construction costs.

Diagonal braces are fixedly connected to the vertical column on the side of each horizontal beam that is relatively away from the vertical column. The two diagonal braces are symmetrically arranged about the vertical column, and the two diagonal braces and the two horizontal beams form an inverted triangle. Hydraulic cylinders are fixedly installed on both ends of each horizontal beam, and holes are provided at both ends of the horizontal beam for the steel strands of the corresponding hydraulic cylinders to pass through.

[0007] Preferably, multiple stiffening plates are evenly connected between the vertical column and the top of the steel-concrete composite column.

[0008] Preferably, a horizontal diaphragm is fixedly installed inside the top of the steel-concrete composite column, and the bottom of the vertical column extends into the interior of the top of the steel-concrete composite column and is fixedly connected to the horizontal diaphragm.

[0009] Preferably, a cross-shaped stiffening rib is fixedly connected between the extended end of the vertical column and the horizontal partition.

[0010] Preferably, the projected size of the hydraulic cylinder is larger than the cross-sectional size of the horizontal beam, and a hydraulic cylinder support stiffening rib is fixedly installed on the outer side of the horizontal beam at the location of the hole.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 As shown, this embodiment of the utility model provides a column-top inverted triangular double-lifting-point support, fixedly installed on the top of a steel-concrete column 1. The column-top inverted triangular double-lifting-point support includes a vertical column 2 fixedly installed at the bottom of the steel-concrete column 1. Two horizontal beams 3 are vertically fixedly installed on both sides of the top of the vertical column 2. Diagonal braces 4 are fixedly connected to the vertical column 2 on the side of each horizontal beam 3 that is relatively away from the vertical column 2. The two diagonal braces 4 are symmetrically arranged about the vertical column 2, and the two diagonal braces 4 and the two horizontal beams 3 form an inverted triangle. Hydraulic cylinders 6 are fixedly installed on both ends of the horizontal beams 3, and holes 13 are provided at both ends of the horizontal beams 3 for the steel strands 7 of the corresponding hydraulic cylinders 6 to pass through. It should be noted that in this embodiment, multiple stiffening plates 5 are evenly connected between the vertical column 2 and the top of the steel-concrete column 1. The stiffening plates 5 prevent the lifting support from overturning as a whole, enhancing the stability of the lifting support and the safety during the lifting process.

[0027] Furthermore, such as Figure 2 As shown, in this embodiment, a horizontal diaphragm 10 is fixedly installed inside the top of the steel-concrete composite column 1, and the bottom of the vertical column 2 extends into the interior of the top of the steel-concrete composite column 1 and is fixedly connected to the horizontal diaphragm 10. Figure 4 As shown, a cross stiffening rib 11 is fixedly connected between the extended end of the vertical column 2 and the horizontal diaphragm 10. When the lifting weight is large or excessive, the steel pipe concrete column 1 is equipped with a cross stiffening rib 11 and a horizontal diaphragm 10 reinforcement node during factory manufacturing, which can ensure the stability of the bottom of the lifting support and prevent the column top end plate from being deformed due to excessive tension.

[0028] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the projected size of the hydraulic cylinder 6 is larger than the cross-sectional size of the horizontal beam 3. A hydraulic cylinder support stiffening rib 12 is fixedly installed on the outer side of the horizontal beam 3 at the position of the hole 13. It should be noted that the hydraulic cylinder support stiffening rib 12 is set at the position of the hole 13, and works together with the diagonal brace 4 to ensure that the horizontal beam 3 effectively resists deformation and bending when subjected to force during the lifting process.

[0029] Please see Figure 1 As shown, in this embodiment, the steel strands 7 of the two hydraulic cylinders 6 pass through the corresponding holes 13 and are used to fix them to the structural members 8 located on the ground. After the lifting bracket is installed and welded, it is connected to the structural members 8 assembled on the ground through the steel strands 7 and lifted as a whole. After the lifting is completed, the inserting members 9 are installed. After the inserting is completed, the hydraulic cylinders 6 and the lifting bracket are disassembled and removed.

[0030] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
