Background
The roof is an enclosure structure at the uppermost part of the house, and the roof should meet the corresponding use function requirements and provide a proper internal space environment for the building. The roof is also the bearing structure of the roof of the house and is limited by factors such as materials, structures, construction conditions and the like.
The roof can be generally divided into a wood roof, a steel roof and a concrete roof according to materials, wherein the wood roof is popular with people from ancient times to present due to the fact that raw materials of the wood roof are easily available, and the wood roof is also the most widely applied roof. However, in actual construction, we find that the conventional wood truss roof still has certain disadvantages, such as:
1. the traditional wood truss roof is troublesome to build, and the whole structure is not stable enough, so that the traditional wood truss roof is difficult to build in large batch;
2. traditional wood truss roof is when putting up, and the slope on roof is difficult to adjust, can only put up the roof of the limited slope according to the material, and the practicality is relatively poor.
The Chinese patent publication number is: the invention patent of CN101644084B discloses a light wood structure roof truss and a construction method thereof, wherein, the members forming the truss comprise members and nodes, the members comprise chords of wood structure and web members of wood structure, and two upper chords and a lower chord form a triangle; vertical web members are arranged between the upper chord member and the lower chord member, inclined web members are arranged between two adjacent vertical web members, the vertical web members and the inclined web members form K-shaped node connection with the upper chord member, and the inclined web members and the vertical web members form V-shaped node connection or V-shaped node connection with the lower chord member; a toothed plate is fixed at each node, and the web members and the chord members are connected by the toothed plates to form the integrated wood truss. The wood-structure light truss is adopted, so that the wood-structure light truss is suitable for flat slope reconstruction of old houses, is also very suitable for newly built and reconstructed engineering projects, and has ideal bearing capacity and safety.
Although the above patent has good load bearing capacity and safety, it is still troublesome to construct and it is difficult to adjust the slope of the roof.
Based on this, we propose an assembled wood truss roof, hopefully solve the shortcomings in the prior art.
