Background technology
Timber is renewable, environmentally friendly, there is good carbon sequestration performance simultaneously, it it is a kind of natural green construction material, having the features such as ratio of strength to weight height, affinity are strong, Engineered Wood Product Manufacturing is more homogeneous in mechanical property, strength variability is little, scantling is flexible, be suitable for large span architecture demand for laminated wood etc. simultaneously。Concrete as being widely used, mechanical property and endurance quality artificial building materials all preferably, in building trade, occupy critical role always。Wood and Combined concrete are formed wood-concrete combined component, various material can be made full use of, there is environmental protection simultaneously, reduce carbon emission, be suitable to the advantages such as industrialization development。
Being similar to steel-concrete combined member, interface node effect in wood-concrete combined component holds the balance, and the structural behaviour of combined member and structure efficiency are determined by interface node system to a great extent。Existing shear connector adopts screw, pin, bar planting etc. as shear connector mostly, and during stress, interface shearing sliding is relatively big, and this is by the structural behaviour of the compound action being substantially reduced between wood and concrete and combined member。How to be obtained in that higher compound action, can guarantee that again combined member has good ductility characteristic simultaneously, be an important topic needing solution badly。
Utility model content
This utility model is in order to overcome the deficiencies in the prior art, the Novel connecting body system of a kind of wood-concrete combined structure is provided, mainly utilize the cementing of vulcanization steel plate and timber, mechanical anchor was combined with cementing connection, thus ensureing that this wood-concrete combined structure of wood not only has significantly high bearing capacity and stiffness, provide enough ductility also by mixed type shear connector。Meanwhile, this combinative structure assemblingization degree is high, fire protecting performance is good, stress system is succinct, meets green energy conservation and the great demand of building industrialization。
The technical solution adopted in the utility model is: the linked system of a kind of wood-concrete combined structure, and including wooden frame, concrete slab and mixed type shear connector, wooden frame is connected with concrete slab by mixed type shear connector；
Described mixed type shear connector includes vulcanization steel plate, rubber layer, Two bors d's oeuveres angle steel and assembling bolt, and described vulcanization steel plate is vertically placed, and the upper end of vulcanization steel plate, by assembling bolt and Two bors d's oeuveres Bolted angle connection, forms T font；Described Two bors d's oeuveres angle steel is embedded in concrete slab in advance, and mixed type shear connector is connected with concrete slab by Two bors d's oeuveres angle steel, and in the plate in concrete slab, arrangement of reinforcement runs through mixed type shear connector；Described wooden frame is placed between the vulcanization steel plate of two mixed type shear connectors, and the contact surface sulfuration of vulcanization steel plate and wooden frame has rubber layer, and this partial vulcanization steel plate is fixed on wooden frame side by epoxy or polyurethane adhesive, and with anchoring screw, its pressurization is fixing。
As preferably, the contact surface of described vulcanization steel plate and wooden frame vulcanizes the rubber layer that a layer thickness is 1-3mm。
Mixed type shear connector described in the utility model is the assembling shear connector of the surface steel plate with vulcanite and double angle, is used for connecting wooden frame and concrete slab；Combination that is cementing and that be mechanically connected is adopted between described mixed type shear connector and wooden frame；The double angle being embedded in concrete slab in advance is adopted to be attached between described mixed type shear connector and concrete slab。
Beneficial effect: the Novel connecting body system of a kind of wood-concrete combined structure of this utility model, is effectively reduced the sliding between wooden frame and concrete, improves anti-bending bearing capacity and the rigidity of combinative structure；The introducing of mixed type shear connector, it is to avoid the brittle break of wooden frame or concrete slab in original combinative structure, by rational Theoretical Calculation, it is ensured that be derived from the ductile fracture of interface locations, it is ensured that reliability of structure。Meanwhile, this structure has excellent fire prevention sound insulation property, thermal and insulating performance and endurance quality。The processing of this type of combinative structure is easier, convenient transportation, plays an important role in the popularization of large span architecture Yu bridge structure field for future。
