Description

Technical Field

[0001] The present invention relates to the technical field of assembled buildings, and in particular to a prefabricated integrally formed bay window structure. Background Art

[0002] A bay window refers to an external window that protrudes from the wall of a building. It can expand the indoor space, broaden the vision and enrich the building facade.

[0003] The Chinese patent discloses an integral prefabricated bay window (authorization announcement number CN204983139U). The present invention prefabricates the bay window cantilever upper plate, the bay window cantilever lower plate and the surrounding external wall panels, that is, multiple flat plates or components are prefabricated into a complete component. During the construction of the prefabricated building, the bay window is hoisted and installed together with the wall. The construction process is simplified and the use effect is obvious.

[0004] Since the above device does not explain how the bay window and the wall are connected and cast with the surrounding buildings, it is necessary to formulate a corresponding casting plan for the overall prefabricated bay window. Otherwise, it is easy for gaps to appear in the connection between the wall and the surrounding buildings. The construction process is still relatively cumbersome and the use effect is not obvious.

[0005] Therefore, a prefabricated integrally formed bay window structure is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a prefabricated one-piece bay window structure in order to solve the above-mentioned problem, thereby improving the problem that the installation and construction process of the existing prefabricated one-piece bay window structure is still relatively complicated.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: a prefabricated one-piece bay window structure, comprising: an external wall panel, an upper cantilever panel and a lower cantilever panel, wherein the upper cantilever panel and the lower cantilever panel are both installed on the surface of the external wall panel, and the external wall panel, the upper cantilever panel and the lower cantilever panel are prefabricated as one piece; a connecting device, wherein the connecting device is installed on the surface of the external wall panel; wherein a rectangular casting groove is provided on the surface of the external wall panel, and during the normal grouting and concrete pouring process of the staff, the concrete can form a rectangular closed structure embedded in the external wall panel along the rectangular casting groove, which can not only increase the connection strength between the concrete and the external wall panel, but also the end face misalignment of the concrete and the external wall panel can reduce the probability of a gap between the concrete and the external wall panel, and at the same time, there is no need for the construction personnel to customize the corresponding casting scheme, which effectively simplifies the installation and construction process of the one-piece bay window.

[0008] Preferably, the vertical cross-section of the rectangular casting trough is in an I-shape, which can further increase the connection strength between the concrete and the external wall panels after solidification, and further improve the stability of the external wall panels in use.

[0009] Preferably, the upper cantilever plate and the lower cantilever plate are installed with vertical support plates, and the vertical support plates, the external wall panels, the upper cantilever plate and the lower cantilever plate are prefabricated as one piece, which can reinforce the upper cantilever plate and the lower cantilever plate, making the operation of the entire bay window structure more stable.

[0010] Preferably, the connecting device includes four groups of connecting steel bars, which are respectively embedded in and installed on four end faces of the external wall panel connected to the rectangular casting trough. The connecting device can increase the connection tightness between the external wall panel and the surrounding prefabricated building structural members, thereby improving the sturdiness of the bay window after installation.

[0011] Preferably, the cross-sectional shape of the connecting steel bar is U-shaped, and the opening of the U-shape faces the rectangular casting trough, which can reduce the probability of deformation of the connecting steel bar during casting or operation, so as to ensure the stability of the connecting steel bar.

[0012] Preferably, the number of the connecting steel bars in each group is not less than twenty, and the spacing between two adjacent connecting steel bars is the same, which can increase the connection between the external wall panels and the surrounding prefabricated building structures, and further improve the sturdiness of the bay window after installation.

[0013] Preferably, the connecting device also includes two reinforcing steel bar frames, both of which are embedded and installed inside the external wall panel, and both ends of the connecting steel bar are fixedly connected to the two reinforcing steel bar frames respectively, which can connect all the connecting steel bars together to reduce the difficulty of the bay window during the prefabrication process.

[0014] The beneficial effects of the present invention are:

[0015] During the normal grouting and concrete pouring process of the staff, the concrete can form a rectangular closed structure embedded in the external wall panel along the rectangular pouring trough. This can not only increase the connection strength between the concrete and the external wall panel, but also the end face misalignment of the concrete and the external wall panel can reduce the probability of gaps between the concrete and the external wall panel. At the same time, there is no need for construction personnel to customize the corresponding pouring plan, which effectively simplifies the installation and construction process of the one-piece bay window.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, a prefabricated integrated bay window structure comprises: an external wall panel 1, an upper cantilever panel 2 and a lower cantilever panel 3, the upper cantilever panel 2 and the lower cantilever panel 3 are both installed on the surface of the external wall panel 1, and the external wall panel 1, the upper cantilever panel 2 and the lower cantilever panel 3 are prefabricated as a whole; a connecting device 4, the connecting device 4 is installed on the surface of the external wall panel 1; wherein, a rectangular casting groove 11 is provided on the surface of the external wall panel 1; the vertical cross-section shape of the rectangular casting groove 11 is an I-shape; the upper cantilever panel 2 and the lower cantilever panel 3 are installed with vertical support plates 5, the vertical support plates 5, the external wall panel 1, the upper cantilever panel 2 and the lower cantilever panel 3 are prefabricated as a whole, since the present application does not make improvements to the integrated prefabricated molding, at this time, the integrated prefabricated molding of the vertical support plates 5, the external wall panel 1, the upper cantilever panel 2 and the lower cantilever panel 3 are the same as the integrated prefabricated molding process and flow in the comparative case, which is a mature technology disclosed in the art and will not be repeated here.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the connecting device 4 includes four groups of connecting steel bars 41, which are respectively embedded and installed in the four end faces of the external wall panel 1 connected to the rectangular casting trough 11; the cross-sectional shape of the connecting steel bars 41 is U-shaped, and the opening of the U-shape faces the rectangular casting trough 11; the number of connecting steel bars 41 in each group is not less than twenty, and the spacing between two adjacent connecting steel bars 41 is the same; the connecting device 4 also includes two reinforcing steel bar frames 42, which are both embedded and installed in the interior of the external wall panel 1, and the two ends of the connecting steel bars 41 are respectively fixedly connected to the two reinforcing steel bar frames 42.

[0024] When the present invention is in use, the construction workers first weld the connecting steel bars 41 to the steel bars in the surrounding prefabricated building structures, and then seal the side openings of the gap between the external wall panel 1 and the surrounding prefabricated building structures with wooden formwork. Then the workers pour concrete into the gap between the external wall panel 1 and the surrounding prefabricated building structures from top to bottom, and the concrete enters the rectangular casting groove 11 along the gap. When the gap and the interior of the rectangular casting groove 11 are filled with concrete, wait for enough time for the concrete to fully solidify. Compared with the existing direct and straight casting method, the concrete is embedded in the external wall panel 1 through the rectangular casting groove 11, which not only increases the connection strength between the concrete and the external wall panel 1, but also the end face misalignment of the concrete and the external wall panel 1 can reduce the probability of a gap between the concrete and the external wall panel 1. At the same time, the construction workers do not need to customize the corresponding casting plan, which effectively simplifies the installation and construction process of the one-piece bay window.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
