Description
Technical field
The utility model relates to technical field of bridge engineering, specifically provide a kind of timber structure box beam.
Background technique
Since box-beam structure has, section torsional rigidity is big, be effective against positive hogging moment, whole stress and structure are being applied
The advantages that having good stability in work and use process, box beam has been widely used in science of bridge building, but most of box beams are steel
Reinforced concrete box beam or steel box-girder.The building materials such as concrete and steel can discharge great amount of carbon dioxide and dust in process of production, together
When the reinforced concrete structure scrapped will cause a large amount of solid refuses, pollute and destroy natural environment, do not meet sustainable development
Exhibition theory.With social development and progress, green wooden building materials and timber buildings are just gradually had been favored by people.
The sectional dimension of general wooden frame is relatively little, and section bearing capacity is limited, is not suitable for building across big biggish structure,
Therefore, in order to improve this case, such as Chinese Patent No. " 201610102987.7 " number, a kind of " box high-strength bamboo collection is disclosed
Become a useful person beam and preparation method ", top plate and bottom plate are connected as by card slot and shearing resistance bamboo pin by a box beam, but it is non-prestressed
Box beam, also non-CLT material.
CLT full name is Cross Laminated Timber, is a kind of orthogonal laminated wood.CLT has the advantage that (1)
Dimensionally stable, orthogonal laminated wood by length and breadth it is orthogonal mat formation be remarkably improved the dimensional stability of plate construction；(2) load-carrying properties
By force, the mechanical property of orthogonal laminated wood is more uniform in both direction in length and breadth, while by removing lamination list in the fabrication process
The defect of member, is remarkably improved design strength value, while the plate high-strength light, can give full play to the high feature of the timber ratio of strength to weight；
(3) energy-saving low-carbon environmental protection, prefabrication degree are high.
CLT timber buildings partially replace reinforced concrete structure and steel building at present, but big cross-cutting
Also rarely has application with bridge field.Therefore, there is energy conservation and environmental protection, convenient, stable structure certain features the CLT timber structure case of construction
Beam is badly in need of research and development.
Utility model content
In view of the deficiencies of the prior art mentioned above, the utility model solves the problems, such as are as follows: provide a kind of structure it is simple plus
Work manufactures convenient transportation, energy conservation and environmental protection, the timber structure box beam of good mechanical properties.
Technical solution: a kind of timber structure box beam, including box beam main body, top angle steel, lower part angle steel, screw, top plate are answered in advance
Power muscle, baseboard prestress muscle and anchorage, the box beam main body include wooden top plate, wooden bottom plate and wooden web, wooden top plate,
The connector of wooden bottom plate and wooden web is top angle steel, lower part angle steel and screw；In the wooden top plate and wooden bottom plate
It is reserved with top plate presstressed reinforcing steel duct and baseboard prestress muscle duct respectively；The top plate presstressed reinforcing steel and baseboard prestress muscle
Anchorage is flat anchor.
Further, the wooden top plate, wooden bottom plate, wooden web wood materials be CLT plate.
Further, the reserved baseboard prestress muscle of the reserved top plate presstressed reinforcing steel duct of the wooden top plate, wooden bottom plate
Duct is CLT plate vacant veneer and presstressed reinforcing steel duct for being formed during assembly.
Further, the wooden web is that the oblique 45 degree of directions of CLT plate are cut, square.
Further, the top angle steel is arranged in wooden top plate and wooden web outside junction, the lower part angle steel cloth
It is placed in wooden bottom plate and wooden web outside junction.
Further, the top angle steel, lower part angle steel length are consistent with box beam main body longitudinal length.
Further, the top angle steel, lower part angle steel two sides are uniformly arranged bolt hole compatible with screw.
The utility model has the advantages that (1) the utility model makes full use of the physico mechanical characteristic of CLT plate high-strength light, therefore box beam has
There are higher bending bearing capacity and rigidity；(2) box beam uses oblique 45 degree of CLT plates as wooden web, ingenious that CLT plate is utilized
Design feature, formed similar truss structure, greatly enhance box-beam structure stability；(3) in wooden top plate and wooden bottom
Plate wears drawing presstressed reinforcing steel, reduces the cracking of plate, enhances the durability of structure, improves applicable span；(4) box-beam structure
Composition is simple, easy to process to make, transport installation, improves site operation efficiency, while energy conservation and environmental protection.
