Description

Technical Field

[0001] The invention belongs to the field of box-board house construction engineering, and in particular relates to an assembled simple house with a reinforced earthquake-resistant structure. Background Art

[0002] With the continuous development of the national prefabricated building industry, the technical requirements for green, environmentally friendly and civilized construction are getting higher and higher. Steel structure has relatively significant advantages. It is not only light in weight and strong in strength, but also has outstanding plasticity and toughness. It has a high degree of assembly. The most important thing is that it basically conforms to the relevant concepts of green energy conservation and environmental protection advocated by current construction projects. Therefore, it has gradually been widely used in various construction projects. However, since the traditional steel structure beam-column connection is widely used in the form of welded nodes, this connection method has very strict requirements on the skills of welding workers and the climate conditions of the construction site; at the same time, a large number of welding nodes will have certain safety hazards, which will increase the detection cost in the project; and the transportation cost of large welded components is relatively high. my country is located in multiple earthquake zones, so the frequency of disasters such as earthquakes is relatively high, which also poses a very serious threat to the safety of people's lives and property. Based on this, we must pay attention to the in-depth exploration of the actual seismic resistance of steel structures in order to create better quality steel structure buildings. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides a prefabricated simple house with a reinforced earthquake-resistant structure. The steel structure has relatively significant advantages. It is not only light in weight and strong in strength, but also has outstanding plasticity and toughness. It has a high degree of assembly and, most importantly, it basically complies with the relevant concepts of green energy conservation and environmental protection advocated by current construction projects. Therefore, it has gradually been widely used in various construction projects. Prefabricated box panel houses have significant performance advantages such as ensuring the quality of construction materials and process control, short construction processing cycle, and low environmental pollution. In the design of the structural system, it is necessary to have a reasonable force transmission path to ensure that it can meet the requirements in terms of energy consumption, load-bearing and stiffness. At the same time, in the design, it is necessary to avoid the impact of partial component and structural damage on the wind load, earthquake and gravity load capacity of the entire structure, and the application of strengthening measures for the weak positions in the system still requires further research work.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An assembled simple house with a reinforced earthquake-resistant structure includes an H-shaped steel beam, a door and window wall, an H-shaped steel load-bearing column, and a corrugated steel plywood wall. The H-shaped steel load-bearing column includes an H-shaped steel load-bearing column frame, an H-shaped steel load-bearing column bottom plate, a flange splicing plate, and a web splicing plate. A bottom plate damper is arranged in the middle of the H-shaped steel load-bearing column bottom plate; the end of the transverse H-shaped steel beam is plugged with the flange splicing plate and the web splicing plate of the H-shaped steel load-bearing column, and the H-shaped steel beam is fixed by connecting bolts passing through the reserved bolt holes of the flange splicing plate and the reserved bolt holes of the web splicing plate; the end of the longitudinal H-shaped steel beam is plugged with the groove of the H-shaped steel load-bearing column , place the connecting channel steel on the upper and lower sides of the H-shaped steel beam, and use connecting bolts to fix the connecting channel steel to the H-shaped steel beam and H-shaped steel load-bearing column; the corrugated steel plywood wall is composed of corrugated steel plate, thermal insulation protection layer, central interlayer, waterproof membrane, moisture-proof layer, high-strength flat metal surface galvanized steel plate from outside to inside, and a steel pipe shock-absorbing diagonal bracing system is set inside the central interlayer, and the remaining part is filled with thermal insulation material or a closed interlayer space is used to form an air insulation layer; the walls on both sides of the door and window walls are high-strength flat metal surface galvanized steel plates; the corrugated steel plywood wall and the door and window walls are connected to the H-shaped steel load-bearing columns and H-shaped steel beams through high-strength bolts.

[0006] Furthermore, the steel pipe shock-absorbing diagonal bracing system is an integral component prefabricated in a factory, and is composed of additional angle steels, diagonal bracing steel pipes, and connecting balls. Foam metal with energy-absorbing effect is placed inside the diagonal bracing steel pipes and the connecting balls.

[0007] Furthermore, the bottom plate damper is made of high-performance rubber material.

[0008] Furthermore, the outer surfaces of all steel materials in the prefabricated simple houses with reinforced earthquake-resistant structures need to be treated with three layers of anti-rust treatment in advance: primer, intermediate paint and topcoat.

[0009] Furthermore, after the side seams of the door and window walls and the corrugated steel plywood walls are fully soaked with elastic polyurethane glue or foam glue, the wall panel joints are filled and smoothed with a special latex caulking agent for wall panel joints.

[0010] Advantages and effects of the present invention:

[0011] The components of the present invention are all prefabricated in the factory and are convenient for transportation. The components are connected by bolts, which has simple connection, saves construction time, and has a high turnover rate. It is in line with the development direction of prefabricated buildings. The walls have better waterproof and heat-insulating properties, and the steel pipe shock-absorbing diagonal bracing system has a good shock-absorbing effect, which enhances the integrity and earthquake resistance of the building.
