Description

Technical Field

[0001] The present invention relates to the technical field of brackets, and in particular to a multi-directionally expandable movable bracket structure and an assembly method thereof. Background Art

[0002] With the rapid development of my country's steel industry and the demand for large-span spaces for public activities, large-span steel structure buildings are widely used in venues. In order to speed up the progress of on-site construction, the installation of large-span steel structure roofs mostly adopts the construction method of assembling the entire ground and then hoisting or sliding. Therefore, the erection of assembly cradles and brackets becomes a necessary measure. The assembly cradles and brackets provide a stable support platform for ground assembly.

[0003] Due to the lack of standard drawings, current construction mostly uses on-site welding of temporary lattice supports or single-tube supports. Although these two methods can be quickly built according to on-site needs, they are not expandable and adjustable, and their flexibility is limited. Once the lattice support is welded, the size and shape of the support are difficult to adjust, and it cannot adapt to the changing needs in subsequent construction. The bearing capacity of the single-tube support is weak and it is difficult to meet the load requirements under complex working conditions. Restricted by the aspect ratio and stability clauses of the scaffolding support platform in the specification, the lattice support columns and single-tube supports are mostly required to be welded with embedded parts, and their mobility is greatly restricted.

The cross section of the slotted bottom beam 3 is II-shaped. The two perforated end plates 24 are respectively connected to the two ends of the slotted bottom plate 21, the slotted top plate 22 and the web plate 23.

[0073] In this embodiment, the slotted bottom plate 21, the slotted top plate 22, the web plate 23 and the perforated end plate 24 are all made of steel plates, and the slotted bottom beam 3 is welded by multiple steel plates. Since the slotted bottom plate 21 and the slotted top plate 22 are both provided with strip grooves 29, and the slotted top plate 22 is also provided with multiple bolt holes, the cross section of the slotted bottom beam 3 is II-shaped. Through this structure, it is convenient to connect the slotted bottom beam 3 with the connecting plate, and the positions of the bracket basic body 1 and the bracket extension body 2 relative to the slotted bottom beam 3 can be adjusted at will.

[0075] The bracket basic body 1 and the bracket extension body 2 can be used separately, and the bracket basic body 1 and the bracket extension body 2 can also be used in combination. The bracket basic body 1 and the bracket extension body 2 can also be used in combination with the slotted bottom beam 3. The bracket basic body 1 and the bracket extension body 2 can also be used in combination with the slotted bottom beam 3 and the connecting beam 4.

[0076] like Figure 8 As shown, the bracket basic body 1 and the bracket extension body 2 are arranged side by side and at intervals, the first longitudinal beam 25 is parallel to the second longitudinal beam 27, and the first cross beam 26 is arranged opposite to the second cross beam 28, and the second longitudinal beam 27 is arranged farther away from the bracket basic body 1 than the second cross beam 28. At this time, the two first longitudinal beams 25 are respectively on the same straight line with the corresponding second longitudinal beams 27, the first connecting plate 13 and the second connecting plate 18 are connected by the slotted bottom beam 3, and the first column 6 and the second column 10 are connected by the connecting beam 4;

[0077] Or, if Fig. 9 As shown, the bracket basic body 1 and the bracket extension body 2 are arranged side by side and adjacent to each other, the first longitudinal beam 25 is parallel to the second longitudinal beam 27, and the first cross beam 26 is arranged opposite to the second cross beam 28. At this time, the two first longitudinal beams 25 are respectively on the same straight line with the corresponding second longitudinal beams 27, and the ends of the two first longitudinal beams 25 are in contact with the second cross beam 28;

[0078] Or, if Fig.10 As shown, the bracket basic body 1 and the bracket extension body 2 are arranged side by side and adjacent to each other, the first longitudinal beam 25 is parallel to the second longitudinal beam 27, and the first cross beam 26 is on the same straight line as the second cross beam 28. At this time, the outer side of one of the first longitudinal beams 25 abuts against the outer side of one of the second longitudinal beams 27, and one side of the first connecting plate 13 is connected to the slotted bottom beam 3;

[0081] Five combination forms are given above, but are not limited to these five combination forms. Through different combinations, the structure can exhibit different combination forms and thus adapt to different use conditions.

[0082] The components of the multi-directionally expandable movable bracket structure of the present invention can be combined in multiple directions, can be adjusted in installation, and can be expanded into groups. The present invention can realize bracket structures of different combinations by changing the placement and orientation of the bracket basic body 1 and the bracket extension body 2 in the plane, and selectively installing the slotted bottom beam 3 and / or the connecting beam 4.

Therefore, according to the requirements of the support structure bearing capacity in the use scenario, Figure 8 and Fig.12 The displayed support structures are divided into heavy support structures, Fig. 9 , Fig.10 and Fig.11 The displayed support structure is divided into a medium-sized support structure, a support basic body 1 and a support extension body 2 used alone, that is, a light-weight support structure.

[0084] In the laboratory, by inserting the laboratory's own movable anchor bolts into the strip grooves 29 of the slotted bottom beam 3, the support structure can be quickly fixed and the slotting direction can be arbitrarily adjusted. In addition, by manufacturing columns with different height modules, a single support basic body can serve as a support for the specimen and achieve height matching.

[0085] At the construction site, through different combinations of the bracket basic body 1 and the bracket extension body 2 in the plane and the expansion connection of the bracket extension body 2 in the horizontal and vertical directions, and the optional combination connection method of the slotted bottom beam 3 and the connecting beam 4, the stability of the bracket structure itself can be achieved without fixing the base of the bracket structure, and different load-bearing requirements can be adapted at the same time.
