In the present embodiment, the first wallboard 11 and the second wallboard 12 are into a single integrated structure by concreting, the first wallboard 11
Cross section with the second wallboard 12 is in rectangle, and in other embodiments, the first wallboard 11 and the second wallboard 12 can also be by steel
Plate is formed by connecting, and the cross section of the first wallboard 11 and the second wallboard 12 can also be in other shapes, and concrete shape is according to construction requirement
Depending on.
It as shown in Figures 3 to 5, is that the embodiment of the present invention provides a kind of building structure, which includes that floor is pre-
Making sheet 20, floor in-situ layer 30, concrete 40 and above-mentioned several prefabricated shear walls 10, two adjacent assembleds
It is connected between precast shear wall 10 by floor in-situ layer 30, floor prefabricated board 20 is installed on floor in-situ layer 30 and the first floor
Between 11, concrete 40 is poured in the vacant portion 14 of 12 two sides of the second wallboard.When two adjacent prefabricated shear walls
When 10 interconnection, the second wallboard 12 is resisted against on floor in-situ layer 30, first connecting portion 131 and second connecting portion 132 are made
In the interlaced vacant portion 14 for being set to 12 two sides of the second wallboard, and it is located at the first connecting portion of 12 the same side of the second wallboard
131 with second connecting portion 132 in the same plane, the fill concrete 40 in vacant portion 14 makes first connecting portion 131 and second
Interconnecting piece 132 is embedded in concrete 40, and a part of first connecting portion 131 is embedded in floor in-situ layer 30 in advance, the first connection
The another part and second connecting portion 132 in portion 131 are embedded in concrete 40, thus by prefabricated shear wall 10, floor
Prefabricated board 20, floor in-situ layer 30 and concrete 40 are integrally fixed, and constitute above-mentioned building structure.
The construction method of above-mentioned building structure includes the following steps:
S1, prefabricated floor prefabricated board is mixed by concrete and rebar and is reserved with the several of vacant portion and prefabricated is cut
Power wall.
S2, the bottom end of first prefabricated shear wall 10 is installed on the basis of after, in the upper end of the first wallboard 11
After floor prefabricated board 20 is installed, then it is poured floor in-situ layer 30, a part of first connecting portion 131 is made to be embedded in floor in-situ layer in advance
In 30, another part of first connecting portion 131 exposes the upper end of floor in-situ layer 30.
S3, second wallboard 12 on second prefabricated shear wall 10 is resisted against on floor in-situ layer 30, and
And by the second connecting portion 132 and first prefabricated shear wall 10 on second prefabricated shear wall 10
One interconnecting piece 131 mutually staggers, and the first connecting portion 131 positioned at 12 the same side of the second wallboard exists with second connecting portion 132
In approximately the same plane.
S4, the casting concrete 40 in the vacant portion 14 on second prefabricated shear wall 10 wrap concrete 40
It covers first connecting portion 131 and second connecting portion 132 and is covered on floor in-situ layer 30, keep precast shear wall 10, floor pre-
Making sheet 20, floor in-situ layer 30 and concrete 40 are integrally fixed, to complete the construction of building structure.
In conclusion building structure of the invention has the advantages that the steel bar connecting joints between precast shear wall 10
In pre-buried preceding naked eyes as it can be seen that belonging to positive operation convenient for operation, i.e., casting concrete 40 again of reinforcing bar 13 are first connected, biography is avoided
System bring hidden danger in such a way that grout sleeve connects this contrary operation；Between the prefabricated shear wall 10 of upper and lower level
The connection type that vertical reinforcement 13 is fixed to each other by concrete 40 is not high to the requirement on machining accuracy of precast shear wall 10, can be with
Precast shear wall 10 is avoided because the contraposition of reinforcing bar 13 is not allowed to cause the case where doing over again, construction cost is greatly reduced, is effectively reduced
Difficulty of construction simplifies construction technology, improves construction efficiency, and can guarantee the reliability of precast shear wall connection.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
