Description

Technical Field

[0001] This utility model relates to the field of bay window slab support technology, specifically to a concrete formwork support structure for a bay window slab. Background Technology

[0002] With the rapid development of the construction industry and the increasing sophistication of high-rise residential building construction systems, most high-rise residential buildings now adopt an aluminum alloy formwork + attached lifting scaffolding + exterior wall coating system for construction from a design perspective. Furthermore, in recent years, there has been a significant increase in the use of multiple bay windows and long bay windows in residential unit designs. In the existing bay window pouring process, the design scheme for the aluminum alloy formwork of the bay window upper slab is a fully enclosed cover plate, with only ventilation holes. The upper formwork of the bay window slab is subject to the buoyancy of the concrete, requiring the addition of anti-buoyancy back braces. The traditional method of back brace reinforcement is to drill holes in the horizontal formwork and insert tie bolts for reinforcement. As a result, after pouring, a pre-reserved hole penetrating the floor slab will be left on the horizontal bay window slab. This pre-reserved hole needs to be sealed a second time. Because the outdoor surface of the bay window upper slab is the lower slab of the air conditioner outdoor unit location, it is also in an environment where rainwater easily accumulates. With the increase in service life, the pre-reserved hole penetrating the floor slab after secondary sealing is prone to leakage. Market research has revealed that in recent years, water leakage from pre-reserved holes in floor slabs in completed residential buildings has indeed become one of the main complaints from homeowners and a hot topic in society. This not only causes product quality issues but also seriously affects the reputation of companies due to online public opinion.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 2 As shown in the figure, this application provides a concrete formwork support structure for a bay window upper slab, including a horizontal lower formwork 1, a first vertical formwork 2, a horizontal upper formwork 3, a second vertical formwork 4, and a back rib 5. The first vertical rib is connected to the horizontal lower formwork 1 and the floor slab formwork 6 respectively. The horizontal upper formwork 3 is parallel to the horizontal lower formwork 1, and an upper slab pouring cavity 81 is formed between the horizontal upper formwork 3 and the horizontal lower formwork 1. An end formwork 7 is connected between the horizontal upper formwork 3 and the horizontal lower formwork 1. The second vertical formwork 4 is connected to the horizontal upper formwork 3, and a beam pouring cavity 82 is formed between the second vertical formwork 4 and the first vertical formwork 2. A setting space is formed between the horizontal upper formwork 3 and the second vertical formwork 4. The back rib 5 is located within the setting space. The back rib 5 is connected to the first vertical formwork 2 through a first connector 91 and to the end formwork 7 through a second connector 92. The second connector 92 is located outside the upper slab pouring cavity 81.

[0037] The concrete formwork support structure for the bay window slab provided in this application has its back rib 5 connected and fixed to the horizontal upper formwork 3 and horizontal lower formwork 1 on the outside of the slab pouring cavity 81. This eliminates the need for tie bolts in the middle of the traditional slab concrete formwork reinforcement, reducing the need for later treatment of the bolt holes in the bay window slab concrete. After pouring, the bay window slab is a single, integral structure without holes or gaps, effectively preventing water leakage and ensuring the overall quality of the building.

[0038] Furthermore, reducing the number of openings in the aluminum alloy formwork increases the number of times the formwork can be reused, thereby reducing costs, saving resources, and reducing carbon emissions.

[0039] In some possible implementations, the back rib 5 includes a horizontal portion 51 and a vertical portion 52 vertically connected to the horizontal portion 51. The horizontal portion 51 is connected to the end template 7 via a second connector 92, and the vertical portion 52 is connected to the first vertical template 2 via a first connector 91. The L-shaped double-panel back rib 5 not only has better fit and support effect, but also allows both the horizontal portion 51 and the vertical portion 52 to be reused, further reducing costs, saving resources, and reducing carbon emissions.

[0040] In some possible implementations, the horizontal portion 51 is fitted to the upper horizontal template 3, and the end of the horizontal portion 51 opposite to the vertical portion 52 has an extension extending out of the upper horizontal template 3. The extension is connected to the end template 7 via a second connector 92. The extension ensures that the horizontal portion 51 is located directly above the end template 7, and ensures a stable connection between the horizontal portion 51 and the end template 7.

[0041] In some possible implementations, the two ends of the end template 7 are connected to the lower horizontal template 1 and the upper horizontal template 3 respectively by reinforcing angle steel 10. The second connector 92 passes through the extension, the reinforcing angle steel 10, and the end template 7. The reinforcing angle steel 10 makes the end template 7 more stable, thereby ensuring the stability of the back rib 5 and guaranteeing the supporting effect of the back rib 5.

[0042] In some possible implementations, a horizontal secondary rib 53 is provided between the vertical part 52 and the second vertical template 4. The first connector 91 passes through the beam casting cavity 82, the second vertical template 4, and the horizontal secondary rib 53, and its two ends are respectively limited to the first vertical template 2 and the vertical part 52. When two planes are not properly aligned, large areas may not fit due to debris or slight changes in angle. Construction sites are prone to sand and gravel particles, which can cause the second vertical template 4 to tilt during casting. Therefore, multiple horizontal secondary ribs 53 are spaced apart between the vertical part 52 and the second vertical template 4, providing space for debris and template tilting. This ensures a tight fit between the second vertical template 4 and the horizontal secondary ribs 53, guaranteeing the stable support of the back rib 5 for the second vertical template 4.

[0043] In some possible implementations, both the back rib 5 and the horizontal secondary rib 53 comprise multiple square steel tubes, and both have through holes for connectors to pass through. The back rib 5 and horizontal secondary rib 53, made from square steel tubes, are reusable, thereby reducing costs, saving resources, and reducing carbon emissions. Pre-setting through holes in the back rib 5 and horizontal secondary rib 53 simplifies installation and speeds up the process.

[0044] In some possible implementations, the side of the horizontal lower template 1 facing away from the end template 7 is connected to the lower edge of the first vertical template 2 by a reinforcing angle steel 10. This arrangement can improve the overall integrity of the template, provide good stability, and prevent displacement during pouring.

[0045] In some possible implementations, the first vertical formwork 2 includes a lower vertical plate 21 and a first transition plate 22. The lower vertical plate 21 is connected to the horizontal lower formwork 1 by reinforcing angle steel 10. The first transition plate 22 includes a vertical section and a horizontal section. The vertical section is connected to the lower vertical plate 21 by an assembly, and the horizontal section is perpendicular to the lower vertical plate 21 and connected to the floor slab formwork 6 by an assembly. Installing the first transition plate 22 on the first vertical formwork 2 allows for more accurate corner structures, avoids corner connections, increases connection strength, and does not affect the aesthetics of the corner.

[0046] In some possible implementations, the concrete formwork support structure for the bay window slab also includes a second transition plate. This second transition plate comprises a horizontal transition section 111 and a vertical transition section 112, which are vertically connected. The horizontal transition section 111 is connected to the horizontal upper formwork 3, and the vertical transition section 112 is connected to the second vertical formwork 4. Installing the second transition plate near the corner of the installation space allows for more accurate corner structure construction, avoids corner connections, increases connection strength, and does not affect the aesthetics of the corner.

[0047] In some possible implementations, the concrete formwork support structure for the bay window slab also includes columns 13, which are supported at the bottom of the horizontal lower formwork 1. The other end of the column 13 supports the adjacent lower bay window slab 14 below the support shaft, providing support for the formwork and ensuring its stability during the pouring process.

[0048] Furthermore, both the first connecting piece 91 and the second connecting piece 92 are tie bolts. When the lower vertical plate 21, the first transition plate 22, the horizontal upper template 3, the second vertical template 4, the horizontal part 51, the vertical part 52, the horizontal secondary rib 53 and the end template 7 need to be connected, they can all be connected by bolts.

[0049] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
