Since the 80 s of the 20 th century, there has been much interest in the ecological and sustainable development of buildings. Wood is again gaining attention as a natural building material with low energy consumption, reproducibility and easy decomposition in processing and manufacturing, but wood structures are limited in span, structural form and the like. In order to compensate for the deficiencies of the wood structure itself, a composite wood structure is often used in the design. And the most common wood composite structure is a wood-reinforced concrete composite structure formed by combining wood and reinforced concrete.
The wood-reinforced concrete composite beam is stressed by connecting wood and concrete into a whole by using an anchored shear connector, gives full play to the good tensile strength of the wood and the good compressive strength of the reinforced concrete, and makes full use of the strength and rigidity of the material.
The wood-reinforced concrete composite beam utilizes the armpits on the two sides of the wood beam to further improve the torsion resistance and the bending resistance of the wood-reinforced concrete composite beam, and has good integral stability; meanwhile, the problems of large self weight, long maintenance period, poor recycling performance of demolished wastes and the like of the concrete beam are solved by adopting the wood beam.
SUMMERY OF THE UTILITY MODEL
The technical scheme is as follows: the utility model aims at providing a wood-reinforced concrete composite beam, concrete bending resistance is poor in the solution concrete beam structure, from great, technical defect such as maintenance cycle length, full play wooden beam light is high-strength, the strong advantage of shock resistance, and simultaneously, the concrete of wooden beam both sides adds the armpit part, make the anti-torque performance and the bending resistance of wood-reinforced concrete composite beam promote, the adverse effect of the eccentric pressurized of roof beam has been avoided, be applicable to existing wooden structure consolidate and in, the roof beam component and the wood concrete floor system of small-size wood concrete structure bridge.
The technical scheme of the utility model: a kind of wood-reinforced concrete combination beam, by the reinforced concrete flange plate, timber beam and concrete haunch part make up, characterized by that the reinforced concrete flange plate is made up of setting up the muscle, longitudinal reinforcement, top stud, stud of both sides, bent reinforcement, stirrup and concrete together; the concrete haunching part consists of longitudinal steel bars, concrete and a steel bar mesh; the top stud is a shear connector of the wood beam and the reinforced concrete flange plate, and the studs on the two sides are shear connectors of the wood beam and the concrete haunched part.
The wood-reinforced concrete composite beam is characterized in that the height of the concrete haunch part is 1/5-1/4 of the height of the wood beam.
The wood-reinforced concrete composite beam is characterized in that the top stud and the two side studs are respectively in different specifications.
The wood-reinforced concrete composite beam is characterized in that the effective depth of the top stud nailed into the wood beam is more than one fourth of the length of the top stud and less than one third of the length of the top stud.
The wood-reinforced concrete composite beam is characterized in that the effective depth of the studs at the two sides, which are nailed into the wood beam, is more than one fourth of the length of the studs at the two sides and less than one third of the length of the studs at the two sides.
The utility model discloses an among the component, the peg plays the effect of guaranteeing wood-reinforced concrete composite beam bending resistance normal performance as the shear force connecting piece, and the concrete adds armpit portion and plays the effect of guaranteeing that wood-reinforced concrete composite beam has sufficient resistance to torsion performance, and reinforced concrete flange board plays the effect of bearing with the timber beams.
Has the advantages that: the utility model overcomes traditional concrete beam's not enough has following beneficial effect:
(1) the wood-reinforced concrete composite beam is poured with concrete through the reinforcing mesh to form a concrete haunched part, so that the overall stability and the torsion resistance of the wood-reinforced concrete composite beam are improved.
(2) The wood-reinforced concrete composite beam utilizes the studs as shear connectors, so that the shear resistance and the bending resistance of the beam are improved, meanwhile, the studs are firstly nailed into the wood beam before casting, and after casting, the studs enable the concrete and the surface of the wood beam to be combined more tightly and are not easy to crack.
(3) The wood-reinforced concrete composite beam adopts the wood beam, so that the dead weight of the beam is greatly reduced, the advantages of light weight, high strength, strong shock resistance and reproducibility of the wood beam are fully exerted, and meanwhile, compared with the traditional concrete beam structure, the wood beam is lower in investment cost, higher in cost performance and more attractive in appearance.
(4) The wood-reinforced concrete composite beam has light self weight, the construction cost of the foundation is reduced, scaffolds and templates can be saved during construction, and the construction period is shortened.
(5) The wood-reinforced concrete composite beam has larger unit weight bearing capacity and good elasticity and toughness.
