Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to a steel support structure system. Background Art

[0002] Currently, for industrial multi-storey buildings, cast-in-place concrete structures, prefabricated concrete structures or steel structures are mostly used. These structural systems are difficult to connect on site and have high structural costs.

[0003] For rigid structure systems, steel frame systems or supported steel frame systems are generally used, beam-column joints are connected by bolt welding, and main beams are made of H-shaped steel. The ends of the main beams are negative bending moments, and since the floor slabs are under tension, the combined effect of the steel beams and the floor slabs is generally not considered.

[0004] With the increasing number of multi-story industrial buildings in the country, a new structural system is urgently needed to save construction costs and speed up construction period. Utility Model Content

[0005] The utility model aims to provide a support system that saves engineering costs and speeds up construction period. To this end, the utility model proposes a support structure system, characterized in that it includes multiple unidirectional planar structure systems that surround each other, at least one of the unidirectional structure systems includes:

[0006] A lateral force resistant frame, the lateral force resistant frame at least comprises two first columns, a plurality of first inter-layer beams and a plurality of lateral force resistant supports, the first inter-layer beams are connected between the two first columns, and the lateral force resistant supports are formed between the two first columns;

[0007] A non-lateral force resisting frame, the non-lateral force resisting frame includes a second column and a plurality of second inter-layer cross beam groups, the second inter-layer cross beam group is connected between the second column and the first column close to the second column, the second inter-layer cross beam group includes two second short beams and a second cross beam, the two second short beams are rigidly connected to the first column and the second column respectively, the second cross beam is connected between the two second short beams, and the connection node between the second cross beam and the second short beam is hinged.

[0008] Preferably, the lateral force resisting support is an inter-column diagonal brace; the inter-column diagonal braces are cross-arranged, and the inter-column supports between the first inter-layer cross beams of each layer are in a cross structure.

[0009] Preferably, the lateral force resisting support is a supporting shear wall, and the supporting shear wall is formed between the first interlayer beams of each floor.

[0010] Preferably, the number of the non-lateral force resisting frames is at least one; when the number of the non-lateral force resisting frames is plural, a plurality of the non-lateral force resisting frames are arranged side by side and continuously, and at least one of the non-lateral force resisting frames is close to the lateral force resisting frames.

[0011] Preferably, the first interlayer cross beam is hinged to the first column.

[0012] Preferably, the first interlayer cross beam and the second cross beam are H-shaped steel beams.

[0013] Preferably, the second short beam is a rectangular beam or an H-shaped beam filled with concrete.

[0014] Preferably, the length of the second short beam does not exceed 1 / 4 of the distance between columns.

[0015] Preferably, it further comprises a floor slab, wherein the floor slab is laid on at least the second interlayer beam group, and at least the second beam is connected to the floor slab to form a composite beam structure.

[0016] Preferably, a supporting portion is formed at the bottom of the second short beam facing one end of the second cross beam, and the end of the second cross beam is placed on the supporting portion and is hinged to the second short beam.

[0017] By adopting the above technical solution, the beneficial effects achieved are:

[0018] The connection between the traditional frame beam and the column is rigid, and there are positive and negative bending moments in the cross section, which is not conducive to forming a composite beam with the floor slab. However, the second crossbeam of the utility model is a beam hinged at both ends, which can form a composite beam with the floor slab, greatly saving the amount of steel used in the beam.

[0019] The maximum bending moment in the beam of this system is smaller than that of the beam hinged at both ends to the column because:

[0020] The beam span is smaller than the span of the frame structure beam, the beam bending moment is reduced, and the beam cross-section is reduced.

[0021] The cantilever length of the second short beam is not large, and its maximum bending moment is also smaller than that of the beam of the frame structure.

[0022] The connection node between the second cross beam and the second short beam is hinged, which is convenient for designing into a full bolt connection and simple connection.

[0023] The supporting portion provides a pre-installation position definition for the second cross beam, facilitating the positioning and installation of the second cross beam.

[0024] Non-lateral force resisting frames only bear vertical loads, that is, load-bearing functions, while lateral force resisting frames bear lateral loads, which separates load-bearing and lateral resistance, and helps reduce the amount of steel used in non-lateral force resisting frames.

[0045] Furthermore, the "hinge" in this embodiment is a connection that does not transmit a bend in the steel structure field, which is different from a "rigid connection".

[0046] See also Figure 1 to Figure 6 This embodiment provides a support structure system, including a plurality of mutually enclosed unidirectional planar structure systems, at least one of which includes a lateral force resisting frame 1 and a non-lateral force resisting frame 2; the other unidirectional structure system can adopt a traditional steel support frame system, which will not be described in detail here, and those skilled in the art should be able to know. As a preferred implementation of this embodiment, at least each building corner in the overall support structure system has a lateral force resisting frame 1, but this is not a limitation.

[0047] This embodiment at least includes Figure 2 There are four mutually enclosed single-direction plane structural systems; when the design requirements of the supporting structure system are large, multiple single-direction plane structural systems are enclosed with each other in a criss-cross manner to form the structural system of the building.

[0048] For further information, see Figure 2 and Figure 3 The lateral force resisting frame 1 includes at least two first columns 11, multiple first interlayer beams 12 and multiple lateral force resisting supports. The first interlayer beams 12 are connected between the two first columns 11. The lateral force resisting supports are formed between the two first columns 11 to achieve the lateral force resisting effect; the non-lateral force resisting frame 2 includes a second column 21 and multiple second interlayer beam groups 22. The second interlayer beam group 22 is connected between the second column 21 and the first column 11 close to the second column 21. The second interlayer beam group 22 includes two second short beams 221 and a second beam 222. The two second short beams 221 are rigidly connected to the first column 11 and the second column 21 respectively. The second beam 222 is connected between the two second short beams 221. The connection node between the second beam 222 and the second short beam 221 is hinged.

[0049] The connection node between the first column 11 and the first interlayer cross beam 12 can be hinged, bearing only vertical load. The connection mode of the lateral force resisting support on the lateral force resisting frame 1 is rigid connection, bearing lateral load. Therefore, as a preferred implementation of this embodiment, the lateral force resisting support can be an inter-column diagonal brace 13 or a shear wall.

[0050] Preferably, when the lateral force resisting support is an inter-column diagonal brace 13, the inter-column diagonal brace 13 is cross-arranged, and the inter-column support between the first inter-layer cross beams 12 of each floor is a cross structure; when the lateral force resisting support is a supporting shear wall, the supporting shear wall is formed between the first inter-layer cross beams 12 of each floor.

[0051] This embodiment has at least one lateral force resisting truss 1 and one non-lateral force resisting truss 2, and there is no limit on the number of the two according to the building span and design. In this embodiment, the number of non-lateral force resisting trusses 2 is at least multiple (preferably four); and when the number of non-lateral force resisting trusses 2 is multiple, multiple non-lateral force resisting trusses 2 are arranged side by side in a row, and at least one non-lateral force resisting truss 2 is close to the lateral force resisting truss 1. Similarly, when the number of non-lateral force resisting trusses 2 is as follows: Figure 3 In the fourth embodiment, four non-lateral force resisting frames 2 are arranged side by side in succession, one of which is close to the lateral force resisting frame 1; and the second columns 21 in the subsequent non-lateral force resisting frames 2 are arranged side by side with the second columns 21 of the previous non-lateral force resisting frames 2 in sequence.

[0052] Furthermore, the second short beam 221 of the non-lateral force resisting frame 2 can be rigidly connected to the first column 11 of the lateral force resisting frame 1 or directly integrally formed in the factory.

[0053] Better yet, please combine Figure 5 and Figure 6 , this embodiment also includes a floor slab, which is at least laid on the second interlayer beam group 22, and at least the second beam 222 is connected to the floor slab to form a composite beam structure. The two are connected by bolts 225. Specifically, bolts 225 of the type of bolts are set on the second beam 222. Regardless of whether the floor slab is a cast-in-place floor slab or a composite floor slab, the second beam 222 is finally integrated with the floor slab through the bolts to form a new composite beam structure, and the second beam 222 and the second short beam 221 are hinged, so that the bending moment is not transmitted, which can greatly save the steel consumption of the second beam 222, and the second beam 222 is integrated with the floor slab, thereby improving the structural strength. This embodiment takes the composite floor slab as an example, and the composite floor slab includes a prefabricated bottom plate 25 and post-cast floor concrete. A hole is opened on the precast base plate 25, the position of which corresponds to the bolt 225, and the top of the bolt 225 extends into the post-cast layer of the floor slab. The connection between the beam and the slab is completed by pouring post-cast floor concrete in the post-cast layer (for the convenience of display, the post-cast floor concrete is not shown in the figure).

[0054] Furthermore, in this embodiment, at least the second cross beam 222 is connected to the floor slab to form a composite beam structure, which is interpreted as the second short beam 221 can also be integrated with the floor slab through the bolt 225; even the first interlayer cross beam 12 can be integrated with the floor slab through the bolt 225. The specific implementation can be selected according to actual design requirements.

[0055] In this embodiment, as a preferred choice, the first interlayer cross beam 12 and the second cross beam 222 are H-shaped steel beams. The second short beam 221 is a rectangular beam or an H-shaped beam with concrete poured inside. The length of the second short beam 221 does not exceed 1 / 4 of the distance between columns. The distance between columns here is the distance between the two second columns 21 in the non-lateral force resisting frame 2; or the length of the second interlayer cross beam group 22. The first column 11 and the first interlayer cross beam 12 can be made of steel columns, steel beams or structural columns and structural beams of other materials.

[0056] Further, please combine Figure 4 and Figure 5 In order to facilitate the positioning of the second cross beam 222 and the second short beam 221 before installation, a supporting portion 2210 is formed at the bottom of the second short beam 221 facing the second cross beam 222, and the end of the second cross beam 222 is placed on the supporting portion 2210 and hinged to the second short beam 221. Preferably, the supporting portion 2210 is a supporting plate extending from the second short beam 221, and the purpose is to position the two when they are hinged.

[0057] It should be noted that the rigid connection in this embodiment can be welded, while the hinged connection is assembled by bolts 224. Figure 4 The second short beam 221 and the second cross beam 222 are connected by hinges, and the two extend to form hinge plates 223 respectively. After the hinge plates 223 of the two are overlapped, the holes are opened and the bolts 224 are passed through to connect them as a whole.

[0058] By adopting the above technical solution, the beneficial effects achieved are:

[0059] The connection between the traditional frame beam and the column is rigid, and there are positive and negative bending moments in the cross section, which is not conducive to forming a composite beam with the floor slab. However, the second cross beam 222 of the utility model is a beam hinged at both ends, which can form a composite beam with the floor slab, greatly saving the amount of steel used in the beam.

[0060] The maximum bending moment in the beam of this system is smaller than that of the beam hinged at both ends to the column because:

[0061] The beam span is smaller than the span of the frame structure beam, the beam bending moment is reduced, and the beam cross-section is reduced.

[0062] The cantilever length of the second short beam 221 is not large, and its maximum bending moment is also smaller than that of the beam of the frame structure.

[0063] The connection node between the second cross beam 222 and the second short beam 221 is hingedly connected, which is conveniently designed as a full bolt 224 connection, and the connection is simple.

[0064] The supporting portion 2210 provides a pre-installation position definition for the second cross beam 222 , facilitating the positioning and installation of the second cross beam 222 .

[0065] The non-lateral force resisting frame 2 only bears vertical load, that is, load-bearing function, while the lateral force resisting frame 1 bears lateral load, so that the load-bearing and lateral resistance are separated, which is beneficial to reduce the steel consumption of the non-lateral force resisting frame.

[0066] Furthermore, the utility model is described in detail above in conjunction with the embodiments of the drawings, and a person skilled in the art can make various variations of the utility model according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
