Description
Technical field
The utility model is related to a kind of assembled bamboo and wood-concrete combination beam, belong to the building structure neck in civil engineering
Domain.
Background technology
Building the main problem faced now is being produced and is being constructed as the traditional structural materials of representative using steel and cement
Caused environment influences in the process.It is carried forward vigorously with bamboo and wood knot during China is planned in " 13 " to cope with this challenge
Structure is the green building of representative, and development assembled architecture.Bamboo and wood materials are used as structural material, it should be to have China special
The road of the Green Architectural Development of color.
Since bamboo and wood materials elasticity modulus is low so that the bending stiffness of simple bamboo and wood beam is relatively low, and bearing capacity is often by deforming
Control, this significantly limits the span of bamboo-wood structure and reduces the utilization ratio of material.And the form of composite structure is used,
It in bamboo and wood beam top casting concrete plate, is combined both by shear connector, forms bamboo/wood-concrete combination beam,
This technology is succeeded application in modern wood structure.Compared with simple bamboo and wood beam, combination beam can effectively improve structure
Rigidity and bearing capacity, increase the span of structure, and sound insulation, vibration isolation capability and the thermal and insulating performance of structure can be improved.With biography
The concrete structure of system compares, and combination beam can also improve the cracking resistance of component, effectively reduces the dead weight of structure.In this way, energy
Two kinds of respective advantages of material are given full play to, while having the characteristics that environmentally protective, reduction carbon emission amount, meet building industrialization
The requirement of development.
Assembled bamboo and wood-concrete combination beam is because it is with advantages such as construction efficiency height, wet-less operations, in assembled architecture
In have a good application prospect.The form of construction work of existing assembled bamboo and wood-concrete combination beam is complex, generally prefabricated
During concrete slab or bamboo and wood beam, need for shear connector to be anchored at concrete slab or bamboo and wood beam in a manner of pre-buried
In, then upper and lower two components are connected at the construction field (site).This combination and form of construction work is main is disadvantageous in that：
First, connector is anchored with a component in advance, and positioning requirements are accurate, and component difficulty of processing is big；Second, when assembling at the scene,
Rigging error caused by being processed due to component self-deformation and component, causes connector to be difficult to coincide one by one with preformed hole, scene
Adjustment is difficult, leads to low construction efficiency.Therefore, exploitation novel fabricated bamboo and wood-concrete combination beam, becomes and improves this combination
The key of component construction efficiency.
Invention content
The purpose of this utility model is to provide a kind of novel fabricated bamboo and wood-concrete combination beam, has assembly method letter
The advantages such as list, construction efficiency are high, mechanical property is good.
The technical solution of the utility model is：A kind of novel fabricated bamboo and wood-concrete combination beam, it is characterised in that：In advance
Pre-buried bamboo and wood block (2) in concrete slab (1) processed；The drilling in pre-buried bamboo and wood block (2) and bamboo and wood beam (3), by being inserted into compound cut
Power connector (4) combines precast slab (1) and bamboo and wood beam (3)；The compound shear connector (4), feature
It is：Steel pipe (5) outsourcing ultra-high performance concrete (6)；Tapping screw (7) is anchored at bamboo and wood beam by the duct in steel pipe (5)
(3) in.It is characterized in that：In compound shear connector (4), ultra-high performance concrete (6) mixing of steel fiber or synthetic fibers.
Compared with existing bamboo and wood-concrete combination beam, the utility model has the advantage of：
(1) assembly method is simple, and construction efficiency is high.First, in actual use, concrete slab, bamboo and wood beam are cut with compound
Power connector is prefabricated standard component, separate machined, and the mode of production is simple.Secondly, connector does not need pre-buried, effectively eliminates
The pre-buried rigging error brought.Furthermore it by bamboo and wood block and is embedded in concrete slab, in this way, the peace of concrete slab and bamboo and wood beam
Dress hole live can drill, and installation error problem is also just not present.Alternatively, the mounting hole of two components is pre-drilled in factory,
Scene is arrived, even if there are certain rigging error, since pre-buried bamboo and wood block has preferable deformability, erection tolerance
Larger, the installation difficulty of compound shear connector is small.
(2) excellent in mechanical performance.In combination beam, compound shear connector directly takes on interface shear stress.Outside due to steel pipe
The ultra-high performance concrete of packet has higher ductility and shearing strength, can effectively cooperate with steel pipe, the mechanics of connector
Performance can be not fully exerted.Thus, the combined effect of combination beam is high, excellent in mechanical performance.
In general, the utility model proposes novel fabricated bamboo and wood-concrete combination beam, realizing assembly construction
While efficient, but also with superior mechanical property, the deficiencies in the prior art are overcome, are had a good application prospect.
