Description

TECHNICAL FIELD

[0001] The utility model relates to a bay window overhanging technology field more specifically, relate to a kind of overhanging structure for building bay window. BACKGROUND

[0002] The overhanging structure for building bay window is a building structural component, which extends outward from the main structure of the building, and is used to support the bay window part. This structure mainly bears the self-weight of the bay window, the load such as the load of personnel close to the window, the load of placed articles, and the lateral force of possible wind load. It is the key structure to ensure the stability and safety of the bay window.

[0003] Chinese patent application number: CN218643818U provides an overhanging structure for building bay window, which is reasonable in structure and convenient to construct. By setting an overhanging beam on the outer wall of the building and a connecting assembly on the inner wall of the building, a steel pull rod is installed obliquely on the upper side of the building bay window, avoiding punching holes at the building bay window, effectively ensuring construction safety, and improving construction efficiency. However, the technology mainly relies on the overhanging beam or plate extending outward from the main body of the building to support the bay window. When bearing the load of the bay window, a large bending moment is generated at the root of the overhang, which requires a large cross-sectional size and reinforcement to resist the bending moment, thereby increasing the material cost and structural self-weight. If the existing overhanging structure is a reinforced concrete structure, the formwork setting and concrete pouring of the overhanging part require high standards during construction. Since the overhanging part has no lower support except for the temporary support of the formwork, deformation of the formwork and uneven settlement of the concrete must be prevented during concrete pouring.

[0004] Therefore, an overhanging structure for building bay window is proposed to solve the above problems. UTILITY MODEL CONTENTS

It is more convenient to place initially without the need to erect a steel frame for molding. It can also be adjusted according to the length of the overhang, and it can adapt to different house heights, increasing the practicality.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:
