Description

Technical Field

[0001] The utility model relates to the technical field of steel structure platforms, in particular to a steel structure platform combined with a structural plate. Background Art

[0002] With the continuous development of cities, there are more and more super-high-rise residential and super-high-rise complex buildings in the city center. Since they are located in the bustling central area of ​​the city, the surrounding building environment is complex, the building edge is close to the land red line, and the construction site is small, which cannot meet the construction needs.

[0003] The traditional solution involves constructing a partial basement area, which, after completion, serves as a transportation corridor and material storage yard for the construction site. However, due to structural variations, the basement roofs of some structures are not at the same elevation, making vehicle access impossible. Furthermore, due to load limitations on the basement roof, large machinery such as high-tonnage truck cranes cannot be used, failing to fully meet on-site construction requirements. Another solution involves constructing a steel structure platform, but this also presents challenges such as high cost and the impact of platform construction on the construction schedule.

[0004] Therefore, a steel structure platform combined with a structural plate is in urgent need of research and development. Utility Model Content

[0005] The purpose of the utility model is to provide a steel structure platform combined with a structural plate to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a steel structure platform combined with a structural plate, comprising a foundation bottom plate, vertical supports and a steel floor system, wherein the vertical supports are arranged on the foundation bottom plate, and the steel floor system is arranged on top of the vertical supports;

[0007] The vertical support comprises a lattice column, wherein the column foot plate at the bottom of the lattice column is connected to the foundation bottom plate through an anchor fixing bracket and fixed by anchor bolts, and grouting material is provided between the column foot plate and the foundation bottom plate;

[0008] The vertical support is composed of a number of lattice columns, and the ends of two adjacent lattice columns are connected by flange nodes and fixed by high-strength bolts;

Top plate secondary beams are arranged between the top plate main beams. The steel floor is erected on the top plate secondary beams.

[0010] As a preferred solution, the vertical support uses the original structural floor as the lateral support.

[0011] As a preferred solution, the connection between the lattice columns and the top plate main beams is welding.

[0012] As a preferred solution, the top plate secondary beam and the top plate main beam are connected by high-strength bolts.

[0013] As a preferred solution, the connection between the steel plate floor and the top plate secondary beam is welding.

[0014] Compared with the prior art, the advantages of the present invention are as follows: the main structure floor is used as the lateral support of the lattice column at the bottom, which reduces the material usage of the lateral support of the steel platform and greatly reduces the production cost of the steel structure platform; the vertical steel columns of the steel structure platform are connected by flange nodes, which improves the construction efficiency compared with welding connection; the construction of the steel structure platform is interspersed with the construction of the main civil structure, does not occupy the key construction line, and ensures the construction period of the main civil structure; the steel structure platform adopts the form of lattice columns, and the bottom of the column is supported on the raft slab, which improves the bearing capacity of the steel platform, so that large-scale mechanical auxiliary structures such as automobile cranes and automobile pumps can be supported on the platform for construction; since the steel structure platform is a temporary structure, the steel structure combined installation platform adopted in this method can be quickly dismantled, and the steel components can be recycled after dismantling, which reduces the construction cost and improves the construction efficiency, and has high practical value and promotion value.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0024] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0025] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] In conjunction with the accompanying drawings, a steel structure platform combined with a structural plate includes a foundation base plate 1, vertical supports and a steel floor system, wherein the vertical supports are arranged on the foundation base plate 1, and the steel floor system is arranged on the top of the vertical supports;

[0027] The vertical support includes a lattice column 6, a column foot plate 4 at the bottom of the lattice column 6 is connected to the foundation base plate 1 through an anchor fixing bracket 2 and fixed by anchor bolts 5, and a grouting material 3 is provided between the column foot plate 4 and the foundation base plate 1;

[0028] The vertical support is composed of a number of lattice columns 6 connected together. The ends of two adjacent lattice columns 6 are connected by flange nodes and fixed by high-strength bolts 7.

[0029] The steel floor system includes a steel floor 10, a top plate main beam 8 and a top plate secondary beam 9. The top plate main beam 8 is arranged on the top of the lattice column 6. Top plate secondary beams 9 are arranged between the top plate main beams 8. The steel floor 10 is erected on the top plate secondary beams 9.

[0030] The vertical support adopts the original structural floor as the lateral support.

[0031] The connection between the lattice column 6 and the top plate main beam 8 is welding.

[0032] The top plate secondary beam 9 and the top plate main beam 8 are connected by high-strength bolts 7 .

[0033] The connection between the steel plate floor 10 and the top plate secondary beam 9 is welding.

[0034] The vertical supports adopt lattice columns instead of traditional solid steel columns. There are no connecting beams or connecting rods between the vertical supports. The original structural floor is used as the lateral support of the steel platform. High-strength bolts are used to connect the foundation floor and vertical supports, which greatly reduces the workload of steel structure welding and enables rapid assembly of components.

[0035] The present invention is implemented by taking the following steps:

[0036] 1. Installation of anchor bolts

[0037] To ensure construction accuracy and facilitate smooth connection of the reserved holes in the steel columns with the anchor bolts, a double-layer anchor bolt fixing bracket is used to temporarily fix the anchor bolts. After placement, the anchor bolt fixing bracket can be spot welded to the non-primary load-bearing steel bars in the foundation slab.

[0038] 2. Lattice column installation and correction

[0039] Accurately locate the installation direction of lattice column 1 according to the drawings, align it with the column base plate or the lower lattice column, and slowly lower it so that the four sides of the lattice column are aligned with the four sides below. After the lattice column is in place, perform verticality correction. After the correction is completed, string guy ropes around the column body to ensure stability and accuracy during construction. After the first section of the lattice column is accepted, use grouting material to perform a second grouting of the column base in the gap between the column base plate and the foundation base plate. This ensures the stability of the component while increasing the deformation stiffness of the column base and reducing the disturbance of subsequent processes on the steel column.

[0040] 3. Civil structure construction

[0041] The main concrete structure is constructed after the lattice columns are constructed.

[0042] 4. Installation and calibration of the next section of lattice columns

[0043] According to the basement structure, the installation and correction of the next section of lattice columns are carried out on a one-column-per-floor basis, and the lattice columns are connected with high-strength bolts.

[0044] 5. Construction of the next level of civil structure:

[0045] Carry out civil engineering structure construction and repeat the above process until the basement structure construction is completed.

[0046] 6. Installation of top steel beam

[0047] After the underground main structure is completed, the last section of the structural column is welded to the top plate main beam. The top plate main beam and the top plate secondary beam are connected with high-strength bolts.

[0048] 7. Steel floor installation

[0049] After the secondary roof beams are installed, the steel floor slab is constructed using steel plates and stiffeners. The steel floor slab and the secondary roof beams are welded together. Once completed and accepted, the steel structure platform is ready for use.

[0050] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
