Description
Technical Field
The invention belongs to the technical field of production of assembled wood structures, and particularly relates to an assembled orthogonal glued wood roof/("/" indicates "or", the remainder is the same) bridge deck structure.
Background
Cross-linked plywood (CLT) is a new type of engineered wood product, which is formed by at least three layers of solid wood sawn timber or composite structural boards, which are vertically and alternately arranged and assembled and glued by structural adhesives. As a wood composite material, the wood composite material has the advantages of environmental protection, recycling, reproducibility and the like, and compared with a laminated wood product, the wood composite material has the advantages of good dimensional stability, large breadth, high processing and production efficiency and the like. The orthogonal laminated wood is widely used in structures such as medium and high-rise buildings, schools, houses and special buildings. CLT is a multipurpose product, mainly used for wall and floor.
The fabricated wood structure building refers to a wood structure building formed by prefabricating wood structure components such as walls, roofs and floor slabs in a factory and assembling the wood structure components on site. The most important characteristics of the fabricated wood structure building are as follows: a large amount of site construction is transferred to factory production; computer-aided manufacturing; the quality control of the house is moved from the construction site to the factory, and the strict quality certification management requirements are met.
At present, the CLT is also mostly used for plate type components in wood structures, and the research on bending special-shaped CLT is also less. The vacuum pressurization method for preparing the bending anisotropic CLT plate has complex process and higher cost, and is not applied in a large scale. The CLT is combined with the stress analysis of the roof panel, and the CLT is used as the roof panel, so that when the CLT bears the bending load, the upper layer of the CLT bears the compressive stress, the lower layer of the CLT bears the tensile stress, and the middle transverse layer bears the shear stress, the shear strength of the cross striation of the CLT is poor, and the tensile strength of the bottom layer of the finger-jointed laminate is low, so that the CLT thin plate is difficult to be used as a large-span roof panel.
At present, the technology how to utilize CLT plane plates and wood rods to process and prefabricate a large-span arc-shaped roof/bridge deck in a factory is not discovered for a while.

The invention takes a large-breadth orthogonal laminated wood (CLT) plane plate as a base material, a plurality of wood or metal rod pieces are connected, and the plane plate is tensioned and bent by adopting a pull rod or a pull cable, so that the rigidity of the orthogonal laminated wood panel can be greatly improved, the size stability of the CLT and the compressive strength of the parallel-grain laminate are repeatedly utilized, the thickness of the CLT is reduced, the requirements of assembly construction are met, and the processing precision and the installation efficiency are improved.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the invention discloses an assembled orthogonal glued wood roof/bridge deck structure which is characterized by comprising at least one orthogonal glued wood panel arranged along the span or width direction of the roof/bridge deck; a plurality of wood/metal support bars for supporting the orthogonal plywood panels; at least one pull rod/pull cable which is arranged along the span direction of the roof/bridge deck and is connected with the two ends of the orthogonal glued wood panel and the bottom end of each support rod piece; wherein;
the orthogonal laminated wood panel is formed by alternately assembling and cold-pressing and gluing at least two layers of wood laminates, the two adjacent wood laminates are respectively used as a main shaft laminate and a weak shaft laminate of the orthogonal laminated wood panel, and the wood texture of the main shaft laminate or the weak shaft laminate is parallel to the span direction of a roof/bridge deck structure and mainly bears compressive stress; the grain included angle of two adjacent wood laminates is 15-90 degrees; the wood laminated board is one or a combination of more of solid wood sawn timber, laminated veneer lumber and oriented strand board.
The invention has the characteristics and beneficial effects that:
compared with the existing orthogonal glued wood roof board or bridge deck, the invention combines the stress characteristics of the CLT, the truss and the beam string, adopts the mode of combining the orthogonal glued wood deck, the wooden/metal supporting rod and the pull rod/pull cable, and adopts the thin plate CLT to prepare the assembled orthogonal glued wood roof/bridge deck structure with larger span and width, thereby solving the problem of poor bending resistance of the CLT, avoiding the occurrence of rolling shear damage on the transverse layer of the roof/bridge deck, fully utilizing the pressure strength of the wood grain, and improving the integral rigidity of the roof/bridge deck. Specifically, the invention adopts the orthogonal laminated wood plane plate with a large width and a low thickness, utilizes the deformation redundancy of the plate in the length direction, and enables the CLT to be converted into a space three-dimensional structure from a flat state by connecting the support rod pieces and adopting a pull rod/cable tensioning and fixing mode on the premise of no damage.
