Description

Technical Field

[0002] With the country's call for energy conservation, emission reduction and green buildings, reconstituted bamboo materials have received more and more attention. As an engineering bamboo material, reconstituted bamboo has the advantages of light weight, high strength and green environmental protection. It is a green and high-strength bamboo-based composite material, which is very suitable for use as a building material. In recent years, prefabricated buildings have received more and more attention and development, but domestic prefabricated buildings are mainly based on component assembly. Beams, columns, walls and other components are prefabricated in the factory and then assembled on the construction site. On the basis of component assembly, modular buildings have been developed, and a room is assembled as a module, which further reduces the construction period, labor and material costs. It is the most cutting-edge prefabricated building technology at present.

They have the advantages of low cost and good seismic performance, but they still adopt on-site construction mode, which has disadvantages such as long construction period, high labor intensity, and high material waste. For example, patent application number: 202210953636.2 provides a modular wood structure combined house, but its structural layout is unclear, the force transmission path is unclear, and the connection part is complex in design, which is not convenient for construction.

The number of left and right connections of the floor slab can be installed according to demand, and the space utilization is optimized in the structural design. At the same time, the number of support points is reduced, thereby saving space and improving the economy and efficiency of the structure. The cable-stayed ducts and prestressed tendons can effectively transfer loads, including vertical loads and horizontal loads (such as wind loads), and can provide good structural stability and durability. The space utilization is optimized in the structural design, allowing cantilever structures with larger spans, while reducing the number of support points, thereby saving space and improving the economy and efficiency of the structure.

[0075] As a specific structure of a reorganized bamboo cantilever board 3, a plurality of joists 201 are connected in sequence along the length direction of the reorganized bamboo cantilever board 3. In this solution, a plurality of joists 201 are evenly distributed in the reorganized bamboo cantilever board 3 along its length direction, so as to support the entire bamboo frame as a whole; in addition, the inclined hole can pass through the plurality of joists 201 in sequence, and the second prestressed tendons are fixed by the plurality of joists 201; the joists 201 are evenly arranged along the longitudinal length of the bamboo fiber ply board.

[0076] A rapid construction method is also provided, comprising the following steps:

[0077] S1: In the prefabrication stage, the four walls of the room unit are first made, the wall frame columns 101 are first spliced, and the connection plates are set at the designed connection positions. Then the sound insulation materials and water and electricity pipelines are installed, and finally the two-way orthogonal covering panels are installed. They are connected with nails, and the operation hand holes are reserved at the corresponding connection positions.

[0078] S2: Connect the joists 201, I-beams or trusses with the wall panels using metal connectors such as angle brackets 205, and then install two-way orthogonal sheathing panels on them, connected by nails. When the span is large, horizontal supports should be set up, and bamboo beams with a width of not less than 60mm should be set up on all four sides, with holes corresponding to the vertical connections opened on the beams to form a composite floor.

[0079] S3: transport the prefabricated reorganized bamboo house unit to the construction site. This house unit is a five-sided box. The five-sided boxes of the first layer are first placed according to the pre-planned building space layout, and then connected horizontally by bolts. Then, rubber pads 6 are set at the corresponding positions of the wall panels, and then the five-sided boxes of the second layer are placed. They are vertically connected by bolts or prestressed tendons, and the floors are installed sequentially from bottom to top, or horizontally, to complete the installation of the entire structure.

[0080] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
