[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1-3 As shown, the utility model provides a prefabricated bay window decorative line structure, including a filling block 1, a steel cage 2 and a casting layer 3. The filling block 1 is an EPS foam board, which is lightweight and can effectively reduce the overall weight of the bay window structure. The steel cage 2 is fixedly connected to the main structure, and a cavity is provided therein, and the cavity is adapted to the filling block 1. The filling block 1 is installed and placed in the cavity to reduce the reinforcement ratio and the overall weight of the bay window structure. The casting layer 3 is formed by pouring concrete on the steel cage 2. When the prefabricated bay window decorative line structure of the utility model is manufactured, according to the technical requirements, the filling blocks 1 of corresponding sizes are produced; the steel cage 2 is tied and connected to the load-bearing steel bars of the main structure; the filling block 1 is stably installed in the steel cage 2, and the steel cage 2 is molded and cast with concrete. After solidification, the casting layer 3 is formed, and the construction of the prefabricated bay window decorative line structure is completed. The prefabricated bay window decorative line structure of the present invention is provided with a steel cage 2 with a cavity and a filling block 1 is installed in the cavity, thereby reducing the use of reinforced concrete, lowering the dead weight of the structure, and greatly lowering the overall side.

[0025] like Figure 1 As shown, in the embodiment of the present invention, the steel cage 2 includes a top load-bearing net 201, a vertical pull net 202 and a diagonal pull net 203.

[0026] The top load-bearing net 201 is used to transfer loads to the main structure. Its ends are fixedly connected to the main structure's cantilevered reinforcement bars 4. The top load-bearing net 201 comprises transversely arranged tension bars and stirrups. The tension bars are arranged in two parallel layers, each layer containing four or more tension bars. The stirrups are arranged longitudinally in multiple groups, spaced 10 cm apart, to tighten the transversely arranged tension bars.

[0027] The vertical tension net 202 is arranged at the bottom of the top load-bearing net 201, and its top is fixedly connected to the rear end of the bottom of the top load-bearing net 201. It includes vertical steel bars and first transverse steel bars, which are vertically fixedly connected by bundling; the vertical steel bars are provided in multiple groups, each group is spaced 30-50CM apart, and the first transverse steel bars are provided in 3 groups, each group is spaced 25-30CM apart.

[0028] The diagonal mesh 203 is installed at the bottom of the top load-bearing mesh 201. Its top is fixedly connected to the front end of the bottom of the top load-bearing mesh 201, and its bottom is fixedly connected to the bottom of the vertical mesh 202. The diagonal mesh 203 includes diagonal steel bars and second transverse steel bars, which are tied together to form a vertical fixed connection. The diagonal steel bars are provided in multiple groups, each group is spaced 30-50 cm apart, and the second transverse steel bars are provided in three groups, each group is spaced 25-30 cm apart.

[0029] Furthermore, in order to improve construction efficiency, the vertical steel bars and the diagonal steel bars are bent into a right-angled triangle structure.

[0030] Furthermore, in order to reduce the self-weight of the bay window decorative lines, the filling block 1 is a right-angled triangular prism structure, and accordingly, the longitudinal cross-section of the steel cage 2 is a right-angled triangle. Compared with the rectangular structure of ordinary bay windows, the bay window structure of the utility model greatly reduces the overall volume, thereby effectively reducing the self-weight.

[0031] In order to prevent the filling block 1 in the cavity from being displaced by impact during pouring, a steel bar bracket is fixed on the steel cage 2. The steel bar bracket is made of plastic and has a flywheel-like structure. It limits the displacement of the filling block 1 by contacting the outer side of the filling block 1. At the same time, the steel bar bracket can also support the steel bars and control the pouring thickness of the pouring layer 3.

[0032] In order to prevent the filling block 1 from being broken by the impact of concrete pouring in the later stage, thereby affecting its service life, the outer layer of the filling block 1 is also covered with a hanging net, the mesh size of which is adapted to the concrete particles. While increasing the bonding strength between the filling block 1 and the concrete, it ensures that there is sufficient contact area between the net, the foam board and the concrete, thereby preventing the filling block 1 from being broken by the impact of concrete.

[0033] During the construction of the bay window decorative line structure of the present invention, after completing the steel bar bundling operation of the main building, the two ends of the force-bearing reinforcement group are fixedly connected to the cantilever steel bars 4, and are tightened with stirrups; after completing the construction of the top load-bearing net 201, multiple groups of steel bars bent into a right-angled triangle structure are connected to the bottom of the top load-bearing net 201, and the first transverse steel bar is tied and fixed to the right-angled side, and the second transverse steel bar is tied and fixed to the oblique side, thereby completing the construction operation with the vertical tension net 202 and the oblique tension net 20; the filling block 1 is loaded into the cavity of the steel cage 2, and the steel bracket is used to limit and fix it; the steel cage 2 is supported by formwork and poured; after the concrete solidifies, the formwork is removed to complete the pouring operation of the bay window decorative line structure.

[0034] The utility model provides a prefabricated bay window decorative line structure. By providing a steel cage 2 with a cavity and installing a filling block 1 in the cavity, the use of reinforced concrete is reduced, the dead weight of the structure is lowered, and the overall cost is greatly reduced.

[0035] The utility model provides a prefabricated bay window decorative line structure, wherein the filling block 1 is a right-angled triangular prism structure, and correspondingly, the longitudinal cross-section of the steel cage 2 is a right-angled triangle. Compared with the rectangular structure of an ordinary bay window, the bay window structure of the utility model greatly reduces the overall volume and the reinforcement ratio, thereby effectively reducing the dead weight.

[0036] The utility model provides a prefabricated bay window decorative line structure, in which a steel bar bracket is fixed on the steel bar cage 2. The steel bar bracket is made of plastic material and limits the displacement of the filling block 1 by contacting the outer side of the filling block 1, thereby ensuring the smooth progress of the pouring operation.

[0037] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
