Problems solved by technology

[0003] The traditional steel structure has always used the frame beam-column system, the steel structure is prefabricated in the factory, assembled on site, and the floor is cast-in-place. Although the traditional steel structure is also a prefabricated building in essence, it has a large amount of on-site welding work and a large number of rods. The cast-in-place floor slab is self-heavy, the construction period is long, and the cost is higher than that of ordinary concrete structures. It deviates from the core of fast and economical industrialized buildings. So far, the actual proportion of the entire construction project is relatively low.

Embodiment 1

[0029] A prefabricated composite structure system, including load-bearing components, the load-bearing components include truss steel columns, the truss steel columns are arranged in an "L" shape, there are truss column vertical rods 3 in the vertical direction, and the truss column vertical rods 3 are vertically arranged with Prefabricated steel beams 5, so that the projection of the overall bearing member on the horizontal plane is "L"-shaped; 1 and diagonal rods 2 form a truss structure. Such as Figure 4 As shown, the horizontal webs 1 are arranged parallel to each other, and the two ends of the oblique webs 2 between two adjacent horizontal webs 1 are respectively staggered from the two ends of the two horizontal webs 1, so that two adjacent horizontal The diagonal web bar 2 between the web bar 1 and the two horizontal web bars 1 is in a "Z" shape. This structure utilizes structural features to achieve its own stable balance without the need for temporary supports. The...

Embodiment approach

[0038] A method for implementing a prefabricated composite structure system, comprising the steps of:

[0039] S1 lifts and welds the prefabricated L-shaped truss steel columns at the construction site and the embedded parts in the foundation, and relies on its own structure to achieve stability. The structure of the truss columns is as follows: figure 2 As shown, there are several stiffeners 8 in a linear array on the prefabricated steel beam 5, and high-strength bolts 9 are arranged between two adjacent stiffeners 8;

[0040] S2. After all the truss steel columns are hoisted and welded at one time, the prefabricated steel beams 5 and the truss columns are assembled and connected with high-strength bolts 9;

[0041] S3. Prefabricate the floor slab in the factory. The thickness of the prefabricated slab 4 is 80-120mm. When the floor slab is prefabricated, grid steel bars are placed, and 4 bolts, 9 holes and 6 are reserved at both ends of the slab. The structure of the slab is...

Abstract

The invention discloses an assembled composite structure system and an implementation method thereof. L-shaped truss steel columns are adopted as bearing components and transverse anti-bending components in the vertical direction of the system, the bearing components and the transverse anti-bending components are welded to embedded parts in a foundation on site, and the L-shaped truss steel columns can reach a stable state without temporary supporting after being welded. The L-shaped truss steel column is provided with an outwards-extending beam section in the horizontal direction, and the prefabricated steel beam and the truss column are connected through high-strength bolts at the outwards-extending beam section. Prefabricated reinforced concrete laminated slabs are adopted for floors, and concrete surface layers are cast in place after the prefabricated reinforced concrete laminated slabs are connected with steel beams through studs on site. The external wall body of the system adopts an external hanging type prefabricated wall plate so that the field external decoration work is omitted. The building industrialization degree can be improved, the labor intensity of workers can bereduced, the product quality is easy to control, the building assembly industrialization requirement can be met and the system an be widely applied to the assembled building structures.

Description

technical field [0001] The invention relates to an assembled composite structure system and an implementation method thereof, belonging to the field of structural engineering. Background technique [0002] The industrialization of construction is an important development trend in my country's construction field, and it is also a development direction vigorously promoted and supported by the state. Prefabricated structure is the product of construction industrialization, which has the advantages of fast construction pace, good product quality, low budget cost, high construction efficiency and simple production process. The typical feature of prefabricated buildings is to simplify the on-site construction work and greatly shorten the on-site construction period. The core is to reduce the on-site workload, especially the work that affects the key construction period. [0003] The traditional steel structure has always used the frame beam-column system, the steel structure is p...
