Roof truss of a modular house

Abstract

The invention belongs to the technical field of house building, and relates to a roof truss, in particular to a roof truss of a combined house. The roof truss can be constructed into a double-slope roof to be applied in a roof construction occasion for a permanent or temporary house. A main structure comprises two first roof truss bodies, a second roof truss body and a main ridge; the first roof truss bodies, the second roof truss body and the main ridge are all of an integral platy structure poured by reinforced concrete, the two first roof truss bodies with the same size structure are perpendicular to the two ends of the second roof truss body which is of a plane triangle structure and are of an H-shaped structure, the main ridge is located over the first roof truss bodies and the second roof truss body, the middle of the main ridge is connected with the top of the second roof truss body in a clamped mode, and the two ends of the main ridge are connected with the tops of the first roof truss bodies in a clamped mode respectively. The roof truss is simple in structure, resistant to water and fire, capable of achieving heat preservation and thermal insulation, high in construction speed, flexible to dismount and mount, high in replacing property, low in comprehensive manufacture cost, high in strength and anti-seismic property and long in service life and has a good economic benefit and application prospect.

Description

Technical field: [0001] The invention belongs to the technical field of house construction, and relates to a roof truss, in particular to a roof truss of a combined house, which can be constructed into a double-slope roof and is used for roof construction of permanent or temporary houses. Background technique: [0002] The construction of permanent houses generally adopts concrete structures, which are directly poured on the ground foundation. The construction procedures are complicated, the cycle is long, time-consuming and labor-intensive, which not only pollutes the environment, but also is difficult to move, and the cost of demolition and construction is extremely high; wood structures can also be used. Handmade, but the quality is difficult to guarantee, and the strength is low, the earthquake resistance is poor, and the labor cost is high; the steel structure house is also widely used, and its construction speed is fast, but its fire resistance, corrosion resistance and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and seek to provide a roof truss for a combined house. Three equal-height roof trusses and a main ridge are assembled into a double-slope type of combined house using horizontal and vertical buckle connections. Roof, to solve the technical problems of short service life, poor earthquake resistance and easy damage of components of the roof truss of the modular house
