Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to an assembly and installation jig for the "petal" steel structure at the upper part of a tree-shaped special-shaped steel column. Background Technique

[0002] The traditional reinforced concrete frame structure can no longer meet the construction requirements of some large buildings such as railway stations and cultural centers. Therefore, a series of steel structures have been widely used in the construction of large-span space structures. In large-span space structure buildings, tall special-shaped cross-section composite steel columns are often used to combine local characteristics to create a "flowering" tree-shaped and bionic tree shape. Due to its special-shaped structure with complex nodes and high installation height, it has always been a construction difficulty for large tree-shaped special-shaped steel columns. The traditional process generally uses lattice columns + high-altitude bulk method, with a large amount of high-altitude work, low work efficiency, and it is difficult to guarantee the installation accuracy of components.

[0003] In the construction of tree-shaped steel structures, the assembly construction of the tree-shaped "petal" steel structure at the upper part is a key link. The accurate positioning and installation accuracy of steel components are crucial to ensure the structural strength and stability. The traditional high-altitude bulk assembly relies on manual operation, which is not only inefficient but also difficult to guarantee the accurate position of steel bars, thus affecting the safety and reliability of the entire structure.

[0004] Due to the complex shape, nodes and large number of components of the upper "petal" tree-shaped structure, and most of them are curved components, the construction difficulty is relatively large. To ensure the installation quality and accuracy of the steel structure, therefore, during the assembly before hoisting, it is quite dependent on a specific installation jig and requires the stable support of the jig. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an assembly and installation jig for the "petal" steel structure at the upper part of a tree-shaped special-shaped steel column, which can prevent the jig from shifting, is convenient for installation, and is conducive to providing stable support.

[0006] To solve the above problems, an assembly and installation jig for the "petal" steel structure at the upper part of a tree-shaped special-shaped steel column is adopted, which includes:

[0007] A root support, which is placed below the root of the "petal" steel structure;

[0008] A front abdominal support, which is placed at intervals behind the root support and is located below the front abdomen of the root of the "petal" steel structure;

[0009] A rear abdominal support, which is placed at intervals behind the front abdominal support and is located below the rear abdomen of the "petal" steel structure; it includes: a first node support and a second node support, the first node support is arranged at the front of the top node of the "petal" steel structure, and the second node support is arranged at the rear of the top node of the "petal" steel structure;

[0010] The distal support, which is placed at intervals behind the rear abdominal support and is located below the distal part of the "petal" steel structure;

[0011] The first arc-shaped base, which winds around the two end parts of the root support on both sides and the two end parts of the front abdominal support on both sides;

[0012] The second arc-shaped base, which winds around the two end parts of the distal support on both sides, the two end parts of the second node support on both sides and the two end parts of the first node support on both sides, and the end parts thereof are spaced and staggered with the end parts of the first arc-shaped base;

[0013] The first tension rod assembly, which includes a first screw rod passing through the first arc-shaped base and the second arc-shaped base, first gaskets arranged on both sides of the first arc-shaped base and both sides of the second arc-shaped base, and first nuts for tightening the first gaskets;

[0014] The anchor bolt, which fixes the first arc-shaped base on one side to the ground;

[0015] The second tension rod assembly, which includes a second screw rod passing through the end parts of the two first arc-shaped bases and the end parts of the two second arc-shaped bases, second gaskets arranged on both sides of the end parts of the two first arc-shaped bases, and second nuts for tightening the second gaskets.

[0016] With such a structure, the first arc-shaped base is positioned by the anchor bolt, and the two first arc-shaped bases and the two second arc-shaped bases are respectively connected by the second tension rod assembly, which is convenient for clamping the root support, the front abdominal support, the rear abdominal support and the distal support, and preventing the tire rack from shifting;

[0017] As a further improvement of the present utility model, the root support, the front abdominal support, the rear abdominal support and the distal support all include: a base, a vertical pipe fixed on the base, and a horizontal positioning template fixed on the upper end of the vertical pipe, and the positioning templates are distributed on the lower side of the tree crown trunk of the "petal" steel structure.

[0018] As a further improvement of the present utility model, the bases of the rear abdominal supports are arranged at intervals in each row, clamping plates are arranged close to the end parts of the bases, and a third tension rod assembly is arranged, which includes a third screw rod passing through the clamping plates and the second arc-shaped base, third pads arranged on the clamping plates and the second arc-shaped base, and third nuts for tightening the third pads.

[0019] With such a structure, when the middle part of the "petal" steel structure is too wide and the length of the base is insufficient, the third tension rod assembly is convenient for clamping the base with a shorter length, so as to prevent the base from shifting.

[0020] As a further improvement of the present utility model, horizontal tie rods are arranged between multiple adjacent vertical pipes.

[0021] As a further improvement of the utility model, a diagonal brace is arranged between multiple adjacent risers.

[0022] As a further improvement of the utility model, three risers are arranged on the bases of the root support, the front abdominal support and the terminal support. The two side risers are fixed on the base. The two side risers are provided with screw rods, and the screw rods are threadedly connected to the middle riser. The middle riser is slidably connected to the base, and a handle is arranged at the end of the screw rod.

[0023] With such a structure, it is convenient to adjust the middle riser to move it to a suitable position to support the tree crown trunk column in the middle of the "petal" steel structure.

[0024] As a further improvement of the utility model, the first gasket and the second gasket have arc surfaces adapted to the first arc-shaped base and the second arc-shaped base.

[0025] As a further improvement of the utility model, the third backing plate has an arc surface adapted to the second arc-shaped base.
