Description
Technical Field
The utility model relates to a prestressed tendon curved surface CLT roof panel, which is applied to modern wood structures and belongs to the field of wood structure buildings.
Background
The concrete material that present building trade was commonly used pollutes the environment great, and the sustainability is relatively poor, and the dead weight is also great, and timber is as a green, reproducible natural resource, again because strong weight ratio is high, shock-resistant, low energy consumption, easy processing decomposes, obtains the attention of building field. However, wood is an anisotropic material, and the mechanical properties of the wood have large variability and uncertainty, so that the development of wood structure buildings is restricted. In order to make up for the deficiency of traditional timber, CLT is often used in timber construction to replace traditional timber.
Orthogonal laminated wood (CLT) is a novel engineering wood product which is formed by orthogonally assembling at least three layers of solid wood sawn timber or structural composite boards and pressing by using a structural adhesive, and is replacing part of reinforced concrete and brick-concrete structure buildings due to the advantages of high strength, strong bearing performance, high dimensional stability, good fire resistance and the like. In addition, the CLT also has good sound insulation and heat insulation performance, and due to the characteristic of orthogonal gluing, the CLT plate can provide high dimensional stability and is very suitable for floors and wallboards with large span and size. At the same time, due to the relatively high stiffness and bi-directional strength of the CLT slab, its many properties are very close to those of the concrete slab. CLT usually adopts the prefabricated mode of mill to produce, carries out the precision according to structural design's needs and processes, and this kind of mode of production has greatly improved the efficiency of construction, reduces construction cost.
In summary, the utility model provides a prestressed tendon curved surface CLT roof panel, which has higher bearing capacity, and the prestressed tendons counteract tensile stress generated in the structure, increase the bending rigidity of the structure and prolong the service life of the structure. The prestressed tendon anchoring device can prevent the prestressed tendon from retracting, so that the prestressed tendon is prevented from generating prestress loss. The compressive strength of the curved surface CLT plate and the tensile strength of the prestressed tendons are fully utilized. Finally, the utility model can be prefabricated in advance, thereby reducing the construction period and the construction cost.
