Problems solved by technology

[0003] The first type is the primary and secondary beam structure of the reinforced concrete floor. Due to the large span of this concrete primary and secondary beam structure, the section determined according to the beam span will increase accordingly, and the height-span ratio is generally 1 / 15 to 1 / 12. , the floor structure has a high weight ratio and poor economic performance
[0004] The second is the one-way main beam structure of section steel-reinforced concrete floor. This structure is only suitable for one-way layout due to the section steel in the beam, considering the complicated construction of beam intersection joints.
Although the steel structure beam-concrete laminated floor slab has a light weight, in order to meet a certain comfort level, its height-span ratio may be higher than that of reinforced concrete, and its steel consumption is large, and its economic performance is not good
[0006] The fourth type is the steel grid structure, but this type of structure is generally not used for floor slabs with floor functions, and its height-span ratio is also large, and the comfort is not good

Embodiment 1

[0038] When the length-span ratio of the large-span space is greater than 2, the horizontal support frame 3 should be arranged in one-way and multiple lanes. The horizontal support frame 3 adopts a one-way multi-channel arrangement, and several horizontal support frames 3 are arranged in sequence along the direction with a longer span, and corresponding support columns are supported under the two ends of the horizontal support frame 3, and the connecting support beams 4 are vertically connected Several horizontal support frames 3 can further improve the structural stability and bearing capacity of the horizontal support frames 3 .

[0039] In preferred embodiment 1, the support structure 1 is provided with floor support columns 11, and the spacing between the floor support columns 11 is set at half of the normal column span of 8-10m, which meets the standards of floor construction and is safe. Higher, and support the horizontal support frame 3 on the floor support column 11. ...

Embodiment 2

[0044] Compared with Embodiment 1, the horizontal support frame 3 is arranged differently in Embodiment 2. When the long-span ratio of the large-span space is not greater than 2, the horizontal support frame 3 should be arranged in two-way and multiple lanes. Several horizontal support frames 3 are vertically arranged along the horizontal and vertical directions of the floor structure, and the corresponding vertical support structures are supported below them.

[0045] In preferred embodiment 2, the span-to-height ratio of the upper chord horizontal support beam 31 is also taken as 1 / 30 to 1 / 40 of the total span of the space, the beam width is taken as 1 / 4 to 1 / 2 of the beam height, and the end is compressed One section of the beam 32 is supported on the upper chord horizontal support beam 31, and the other end is supported on the floor support column 11 or the lower support beam 12 between the floor support columns 11. The height and width of the support section can be taken t...

Abstract

The invention relates to a single-inclined-strut large-span floor structure system which comprises a supporting structure and a floor structure, the supporting structure is connected to the lower portion of the floor structure, the floor structure is provided with a plurality of horizontal supporting frames, and the horizontal supporting frames are all arranged on the supporting structure. The invention discloses a single-inclined-strut large-span floor structure system, the whole space is divided into three sections in a large span mode through end pressed inclined beams at the two ends, the span and the section height of an upper chord horizontal supporting beam are reduced, and the utilization rate of materials is greatly increased mainly through transmission of internal axial force instead of bending moment and shearing force of a horizontal supporting frame; the resource consumption is reduced, and the structural rigidity and the comfort degree are greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a single-bracing large-span floor structure system. Background technique [0002] In the current existing technology, the 24-50m long-span structural floor generally adopts the following structural forms: [0003] The first type is the primary and secondary beam structure of the reinforced concrete floor. Due to the large span of this concrete primary and secondary beam structure, the section determined according to the beam span will increase accordingly, and the height-span ratio is generally 1 / 15 to 1 / 12. , Its floor structure has a high proportion of self-weight and poor economic performance. [0004] The second is the one-way main beam structure of section steel-reinforced concrete floor. This structure is only suitable for one-way layout because of the section steel in the beam and considering the complicated construction of beam intersection joints. Its ...
