Description

Technical Field

[0001] This utility model relates to the field of construction technology for walls under openings, and in particular to an integrated cast-in-place structure for walls under window openings on exterior walls. Background Technology

[0002] In the construction of building exterior walls, window openings are essential, providing the foundation for window installation. Generally, the wall below the window is constructed and installed using masonry blocks or separately poured concrete. Whether it is a masonry block or concrete wall, it bears the load independently. However, when the window is heavy or to ensure that the wall below the opening is more integrated with the exterior wall in terms of load-bearing capacity, it is necessary to design the wall below the opening to be poured as an integrated unit with the exterior wall. Utility Model Content

[0003] This utility model provides an integrated cast-in-place structure for the wall below the window opening, which solves technical problems such as the setting of steel reinforcement in the wall below the window opening, the connection with the side wall, and the overall construction of the wall below the opening.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integral cast-in-place structure for the wall below an exterior window opening includes a floor slab, a window opening located above the floor slab, a wall below the opening located between the window opening and the floor slab, side walls located on both sides of the window opening, and an insulation layer and an outer layer located on the outside of the wall below the opening. The lower wall of the opening includes the lower wall concrete and the lower wall steel reinforcement installed in the lower concrete. The lower wall of the opening is integrally cast and connected with the side wall. The reinforcement of the wall below the opening includes horizontal bars set horizontally and stirrups set vertically below the opening. The horizontal reinforcing bars at the bottom of the opening extend into the side wall at both ends.

[0005] Furthermore, the side wall includes side wall concrete, side wall vertical bars set vertically in the side wall concrete, side wall tie bars set between adjacent side walls, and side wall stirrups connected to the outer periphery of the side wall vertical bars and perpendicular to the side wall vertical bars.

[0006] Furthermore, the vertical reinforcement bars of the side wall are installed along the entire length within the height range between floors, and are extended in a denser manner to the wall below the opening; the spacing of the denser reinforcement bars is not less than the diameter of the horizontal reinforcement bars of the wall below the opening.

[0007] Furthermore, the horizontal reinforcement bars under the opening are spaced apart in the vertical direction, and the ends extending into the side wall are tied to the vertical reinforcement bars of the side wall; and the length of the horizontal reinforcement bars extending into the opening is not less than 5 times the diameter of the reinforcement bars.

[0008] Furthermore, the stirrups at the bottom of the opening are placed outside the horizontal reinforcement bars at the bottom of the opening; the stirrups or horizontal reinforcement bars at the bottom of the opening are also tied to the reserved steel bar ends at the top of the floor slab.

[0009] Furthermore, the inner side of the floor slab and the wall below the opening is set as the interior finished surface, and a beam is correspondingly set below the bottom of the wall below the opening.

[0010] Furthermore, the outer end of the floor slab extends out of the wall below the opening, and a fire isolation strip is provided above the extended section and outside the wall below the opening.

[0011] Furthermore, an outward-facing eaves main body is also provided at the top of the wall below the opening. An insulation layer and an outer layer are integrally provided on the outer side of the eaves main body and the outer side of the side wall. The outer layer at the top of the eaves main body is inclined, and the inclination angle is adapted to the drainage angle.

[0012] Furthermore, a window is installed inside the window opening; the outer side of the window is flush with the outer side of the wall below the opening.

[0013] The beneficial effects of this utility model are reflected in: This invention ensures the integrity of the exterior wall by casting the lower wall and side wall together, while also improving the load-bearing capacity of the lower wall. The horizontal reinforcement bars in the lower wall connect with the internal reinforcement bars of the side wall, ensuring end fixation and overall load-bearing capacity. Furthermore, the horizontal reinforcement bars themselves enhance the strength of the lower wall. The eaves structure is cast integrally with the lower wall while maintaining its basic function, facilitating convenient construction. Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The main objectives and other advantages of this invention can be realized and obtained through the methods specifically pointed out in the description. Attached Figure Description
