Description

Prefabricated composite beam shell

Technical field

The utility model relates to a kind of prefabricated composite beam shells, belong to technical field of building construction.

Background technique

Building Trade in China assembled architecture field at present, the common prefabricated exterior enclosure wall of total cross-section, be self-possessed larger, Er Qiecun In beam column nucleus there are the prefabricated and cast-in-place concrete cold seam of contraction, its globality is affected.

Assembled architecture planning has intensively been put into effect since 2015, the publication of year ends 2015《Industrialized building evaluation criterion》, It determines that assembled architecture is popularized in the whole nation in 2016 in an all-round way, and makes a breakthrough；On November 14th, 2015 lives the portion of building and puts into effect《It builds Build industry modernization development outline》Plan to the year two thousand twenty assembled architecture to account for 20% or more the ratio of new building, be filled by 2025 50% or more the ratio of new building is accounted for formula building；State Council puts into effect on 2 22nd, 2016《About greatly developing assembled architecture Instruction》It is required that adaptation to local conditions is wanted to develop the assembled architectures such as prefabricated concrete structure, steel construction and modern wood structure, Strive the time with 10 years or so, the ratio for making assembled architecture account for new building area reaches 30%；On March 5th, 2016 government Work report proposition will greatly develop steel construction and assembled architecture, improve construction standard and quality；On July 5th, 2016 Firmly the portion of building is put into effect《House town and country construction portion scientific and technical project plan assembled architecture science and technology demonstrative project list in 2016》And Disclose scientific and technical project construction assembled architecture science and technology demonstrative project list in 2016；2016 Nian9Yue14 State Council call together Executive Meeting of the State Council is opened, proposition will greatly develop assembled architecture and push industry restructuring upgrading；2016 Nian9Yue27 states Business institute puts into effect《The General Office of the State Council is about the instruction for greatly developing assembled architecture》, to greatly develop assembled architecture and Steel construction key area, the following assembled architecture accounting new building target are given priority to city and are defined.

Summary of the invention

The purpose of this utility model is to provide a kind of prefabricated composite beam shells, can effectively mitigate prefabricated components certainly Weight improves nucleus globality.

The utility model to achieve the goals above, adopts the following technical scheme that：

A kind of prefabricated composite beam shell, it includes the steel reinforcement cage inside concrete layer and concrete layer, steel reinforcement cage Lower half portion is embedded in concrete, and the top half of steel reinforcement cage is exposed outside, and the end of composite beam shell is equipped with the cast-in-place of U-typed and lacks Mouthful.To ensure that the cast-in-place globality of beam column node area.

Further, the groove port of composite beam shell both ends U-typed, in concrete cast-in-situ, the cast-in-place of structural column is mixed Solidifying soil flow is into the groove of the cast-in-place notch of the U-typed of composite beam shell.

Further, the steel reinforcement cage is made of a plurality of transverse direction and vertically staggered reinforcing bar.

The beneficial effects of the utility model：

1, the utility model is in the self weight for mitigating prefabricated components to a certain degree；

2, the utility model is by passing through the globality of building beam column core space is cast-in-place；

3, the utility model is logical can reduce manual work, reduce Contraction in Site.

4, the logical realization the factorial production of the utility model, it is convenient and efficient.

Specific embodiment

1,2,3,4 pair of the utility model is described in detail with reference to the accompanying drawing：

A kind of prefabricated composite beam shell, it includes the steel reinforcement cage 2 inside concrete layer 1 and concrete layer 1, steel reinforcement cage 2 lower half portion is embedded in concrete 1, and the top half of steel reinforcement cage 2 is exposed outside, and the end of composite beam shell is equipped with U-typed Cast-in-place notch 3.It ensure that the cast-in-place globality of beam column node area.

In concrete cast-in-situ, the cast-in-place concrete of structural column flows into the groove of the cast-in-place notch 3 of the U-typed of composite beam shell In.

The steel reinforcement cage 2 is made of a plurality of transverse direction and vertically staggered reinforcing bar.

The groove port of composite beam shell both ends U-typed, in concrete cast-in-situ, the cast-in-place concrete of structural column can be flowed into The groove of composite beam shell contacts structure wall with external wall protection body stronger.
