Description
Technical field
It the utility model is related to a kind of prefabricated U-shaped composite beam.
Background technology
With the iterative method of the new urbanization in China, the landing of the Belt and Road strategy, construction industry has welcome brand-new
Reform Period.At present, China's traditional architecture mode of production in the prevalence of buildings and resources high energy consumption, production efficiency is low, engineering
Quality and the problems such as safety causes anxiety, labor cost is stepped up, shortage of resources is serious.This requires that constructional enterprises must change
The traditional architecture mode of production, meet the requirement of future architecture industry sustainable development.
The defects of prior art and deficiency include it is following some：
(1) live assembling reinforcement supporting module, laborious and leakiness shake running pulp of taking a lot of work, produces voids and pits quality problems；
(2) the site operation cycle is grown, and easily causes the environmental pollutions such as noise, airborne dust；
(3) recycled after service life terminates without hair, remove and produce building waste, cause environmental pollution and resource wave
Take；
(4) traditional precast beam, Prefabricated superposed beam use solid shape more, and from great, transporting and hoisting is costly；
(5), hidden danger of quality and node installation difficulty be present in traditional precast beam, Prefabricated superposed beam and hardened conjunction globality poor
Greatly.
Therefore, for prior art shortcoming, a kind of prefabricated U-shaped composite beam is devised, it is highly developed that it combines industrialization
Steel Structure Industry, coordinate various high performance concrete combination techniques, solve asking for armored concrete node assembling inadequate natural endowment
Topic, site operation problem of environmental pollution, green construction material application problem etc. are significant.
Utility model content
The purpose of the utility model is that a kind of prefabricated U-shaped composite beam is provided the defects of presence for prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of prefabricated U-shaped composite beam, including U-shaped steel
Plate, the concrete layer being adapted with the U-shaped steel plate contour structures, the concrete layer are provided with the outside of the U-shaped steel plate
Reinforced mesh is inside enclosed with, is arranged between the reinforced mesh of two sides and the U-shaped steel plate and is provided with multiple dowels；Institute
State dowel one end to be anchored in concrete layer, the other end is welded on the U-shaped steel plate.
Further, the dowel is arranged in U-shaped steel plate two sides into blossom type.
Further, three lateral surface U-shaped arrangements of the reinforced mesh along the U-shaped steel plate, and by the concrete
Layer is wrapped up to form " U-shaped " shaped steel-Reinforced Concrete Composite Beams.
The beneficial effects of the utility model：The utility model has the following advantages that：
(1) prefabrication standardized production, scantling precision is high, and control errors are in grade.
(2) U-shaped beam is overlapped from heavy and light, is readily transported and is installed, reduces transport and hoisting cost.
(3) composite beam is prefabrication, shortens construction period, beneficial to fine-grained management.
(4) integral hoisting noise is small and effectively prevents dust pollution.
(5) validity period terminates the dismountable renewable resource for returning factory's detection reinforcing, being recyclable reuse, reduces pollution
And waste.
(6) hollow parts scene and floor integral cast-in-situ on the inside of U-shaped beam, ensure that the globality of beam slab, anti-seismic performance height.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A-A to structural representation；
Fig. 3 is B-B direction structural representation in Fig. 1；
Fig. 4 uses scheme of installation to be of the present utility model.
Embodiment
Shown in Fig. 1 to Fig. 3, it is related to a kind of prefabricated U-shaped composite beam, including the U-shaped steel plate 4 as main bearing member, institute
The outside for stating U-shaped steel plate 4 is provided with the concrete layer 1 being adapted with the contour structures of U-shaped steel plate 4, in the concrete layer 1
Reinforced mesh 2 is enclosed with, is arranged between the reinforced mesh 2 of two sides and the U-shaped steel plate 4 and is provided with multiple dowels 3；
Described one end of dowel 3 is anchored in concrete layer 1, and the other end is welded on the U-shaped steel plate 4.Wherein, the dowel 3 is U-shaped
The two sides of steel plate 4 are arranged into blossom type.Due to the setting of dowel 3, being firmly combined with for outsourcing reinforced concrete and U-shaped steel plate ensure that
Reliably, good integrity.
Mentality of designing is：Using the U-shaped steel plate of welding as skeleton, and reinforced concrete enveloped carries out anti-corrosion fire prevention, reinforcing bar
Concrete is made up of reinforced mesh and concrete layer, three side U-shaped arrangements of the reinforced mesh along U-shaped steel plate, and by concrete
It is wrapped to form " U-shaped " shaped steel-Reinforced Concrete Composite Beams.To ensure that peripheral armored concrete is firmly combined with U-shaped steel framework
Reliably, it is welded with dowel along the side elevation of U-shaped steel two, dowel is into quincuncial arrangement.To sum up, steel structure is taken with standardised configuration arrangement of reinforcement perfection
Match somebody with somebody, with reference to the born node connection advantage of steel construction, prefabrication part concrete, reach high prefabricated rate industrialized building standard.
Fig. 4, it is the U-shaped composite beam of the design connecting node schematic diagram with superimposed sheet 5 at the construction field (site), U-shaped composite beam
Support zone at the top of beam side elevation as superimposed sheet 5, superimposed sheet 5 is placed with U-shaped composite beam, being spread with floor top bars
After if, integral cast-in-situ concrete 6.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
