Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to an externally intersecting network inclined column frame structure system. Background Technology

[0002] Cross grids are increasingly favored by architects and structural designers due to their high lateral stiffness and ability to create unique facade effects.

[0003] Intersecting grids are often on the same plane. When architects want to create a single-sloping facade effect, the most common approach is to use non-structural load-bearing components, such as curtain wall components, to cover it. However, a structural frame needs to be set up on the outside of the building to support this non-structural load-bearing component. This makes it difficult to achieve the integrated facade effect of the building structure that the architect wants to present, and it also reduces the usable area of ​​the building. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, such as the inability to present an integrated facade effect of building structure and the reduction of building usable area, and to provide an external cross-grid inclined column frame structure system.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The technical solution of this invention is to provide an externally intersecting grid inclined column frame structure system, including external inclined columns, internal inclined columns, floor components, and internal frame columns, wherein...

[0007] The floor assembly includes several horizontally arranged floor panels and horizontal steel beams located at the bottom of the floor panels to support them.

[0008] The inner frame column is vertically disposed inside the floor assembly and connected to the floor assembly;

[0009] The outer inclined column is inclined on the outer surface of the floor component, and the inner inclined column is inclined on the inner surface of the floor component and intersects with the outer inclined column on the same side to form a unidirectional inclined facade.

[0010] Furthermore, the inner frame column is rigidly connected to the horizontal steel beam of the floor slab at the bottom.

[0011] Furthermore, the intersection of the outer inclined column and the inner inclined column is also located on the horizontal steel beams of the floor around the bottom of the floor slab, and the space between two adjacent intersections on the same outer inclined column is provided with at least one floor slab.

[0012] Furthermore, the floor slab between the intersections has its outer side connected to the outer inclined column and its inner side connected to the inner inclined column, with the outer side of the floor horizontal steel beams around its bottom perimeter.

[0013] Furthermore, the outer inclined column and the inner inclined column are either closely fitted together or have gaps between them.

[0014] Furthermore, the gap between the outer inclined column and the inner inclined column is no greater than 150mm.

[0015] Furthermore, several of the external inclined columns on the same side of the floor assembly are parallel to each other.

[0016] Furthermore, several of the inner inclined columns on the same side of the floor assembly are parallel to each other.

[0017] Furthermore, the outer inclined column, the inner inclined column, and the inner frame column are all box-shaped or circular cross-section steel.

[0018] Furthermore, the horizontal steel beams on the floor are H-shaped steel beams.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The external intersecting grid inclined columns (external inclined columns and internal inclined columns) of the present invention are not in the same plane, that is, the external inclined columns are presented on the outside of the building and the internal inclined columns are hidden in the interior, presenting the facade effect of the single inclined member of the building, realizing the integrated design of the facade building structure.

[0021] (2) The external intersecting grid inclined column of the present invention has large lateral stiffness and large torsional stiffness, and can transmit vertical loads and horizontal loads. Under the condition that the component size is small, it can still meet the overall index requirements of the overall structural system such as lateral displacement, torsional displacement ratio, and period ratio.

[0022] (3) The components used in this invention are small in size and use less steel, which can increase the usable indoor area of ​​the building and has good economic and social benefits. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0033] Example 1

[0034] like Figure 1-6 The diagram shows an externally intersecting grid inclined column frame structure system. This system includes external inclined columns 1, internal inclined columns 2, floor slabs 3, and internal frame columns 4. The floor slabs 3 include several horizontally arranged floor panels 3-1 and horizontal steel beams 3-2 located at the bottom of the floor panels 3-1 to strengthen their rigidity. At least two parallel horizontal steel beams 3-2 are located at the bottom of the floor panels 3-1. The internal frame columns 4 are vertically arranged inside the floor slabs 3 and rigidly connected to the horizontal steel beams 3-2 at the bottom of the floor panels 3-1, used to fix the floor slabs 3. The external inclined columns 1 are inclined on the outer surface of the floor slabs 3, and the internal inclined columns 2 are inclined on the inner surface of the floor slabs 3 and intersect with the external inclined columns 1 on the same side, forming a unidirectionally inclined facade. The intersection of the outer inclined column 1 and the inner inclined column 2 is also located on the horizontal steel beams 3-2 around the bottom of the floor slab 3-1. At least one floor slab 3-1 is provided between two adjacent intersections on the same outer inclined column 1. The outer side of the horizontal steel beams 3-2 around the bottom of the floor slab 3-1 between the intersections is rigidly connected to the outer inclined column 1, and the inner side is rigidly connected to the inner inclined column 2. When the outer inclined column 1 and the inner inclined column 2 are welded to the horizontal steel beams 3-2, they are either tightly fitted together or have gaps; preferably, the gap between the outer inclined column 1 and the inner inclined column 2 is no more than 150mm. Furthermore, several outer inclined columns 1 on the same side of the floor assembly 3 are parallel to each other, and several inner inclined columns 2 on the same side of the floor assembly 3 are parallel to each other.

[0035] Preferably, the outer inclined column 1 is a box-section steel section, the inner inclined column 2 is a box-section steel section, the floor horizontal steel beams 3-2 are H-beams, and the inner frame column 4 is a box-section steel section. The specific dimensions of the above components can be determined according to the actual stress, and the inclination angles of the outer inclined column 1 and the inner inclined column 2 can also be determined according to the actual stress.

[0036] The external intersecting grid inclined columns of this invention are not in the same plane. The external inclined columns 1 are presented on the exterior of the building to achieve the effect of a unidirectional inclined facade. The internal inclined columns 2 are hidden inside the building. The external intersecting grid inclined columns formed by the external inclined columns 1 and the internal inclined columns 2 not only transmit the vertical load of the floor, but also resist the horizontal load. Furthermore, at each floor, the horizontal steel beams 3-2 of the floor are connected to the internal frame columns 4 to form an integral structure, thus realizing the integrated design of the building structure and facade.

[0037] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
