Description

Prefabricated outer shear wall

Technical field

The utility model relates to a kind of prefabricated outer shear walls, belong to technical field of building construction.

Background technique

Building Trade in China assembled architecture field at present, common superposed column are self-possessed larger, and there are beam column core spaces Domain affects its globality there are the prefabricated and cast-in-place concrete cold seam of contraction.

Assembled architecture planning has intensively been put into effect since 2015, and year ends 2015 issued " 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；The portion's of building appearance is lived on November 14th, 2015 " to build Build industry modernization development outline " plan 20% or more the ratio that new building is accounted for the year two thousand twenty assembled architecture, it was filled by 2025 50% or more the ratio of new building is accounted for formula building；On 2 22nd, 2016 State Council put into effect " about greatly developing assembled architecture Instruction " require 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 puts into effect " house town and country construction portion scientific and technical project plan assembled architecture science and technology demonstrative project list in 2016 " simultaneously 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 Be engaged in institute put into effect " 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.

Utility model content

The purpose of this utility model is to provide a kind of prefabricated outer shear walls, can effectively mitigate prefabricated components certainly Weight improves nucleus globality.

To achieve the goals above, the utility model adopts the following technical solution:

A kind of prefabricated outer shear wall, it includes concrete shear force wall, external protection coating and sandwich heat preservation layer composition；

Concrete shear force wall both ends are equipped with "U" type groove, sandwich heat preservation be placed on concrete shear force wall and external protection coating it Between, it is equipped with circular hole at the top of concrete shear force wall, is equipped with framework of steel reinforcement inside concrete shear force wall.

Further, the groove port of concrete shear force wall both ends U-typed, in concrete cast-in-situ, cast-in-place concrete The groove for flowing into concrete shear force wall contacts structure wall with concrete shear force wall stronger.

Further, the circular hole is from top to bottom through concrete shear force wall.

The utility model has the beneficial effects that

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 can reduce manual work, reduce Contraction in Site；

4, the utility model realizes the factorial production, 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 outer shear wall, it includes concrete shear force wall 1, external protection coating 2 and sandwich heat preservation layer composition；

1 both ends of concrete shear force wall are equipped with "U" type groove, and sandwich heat preservation layer 3 is placed in concrete shear force wall 1 and external protection coating Between 2, circular hole 5 is equipped at the top of concrete shear force wall 1, is equipped with framework of steel reinforcement 4 inside concrete shear force wall 1.

The groove port of the 1 both ends U-typed of concrete shear force wall, in concrete cast-in-situ, cast-in-place concrete flows into coagulation The groove of native shear wall contacts structure wall with concrete shear force wall stronger.

The circular hole 5 is from top to bottom through concrete shear force wall 1.
