[0074] Window opening corner connection formwork is a type of formwork used in building construction, mainly for connecting and fixing the inner and outer corners of window openings to ensure the straightness and verticality of the corners after concrete pouring. This type of formwork is typically made of aluminum alloy profiles or high-strength plastics, providing excellent support strength.

[0075] In related technologies, window opening corner connection templates typically include a bottom template and side templates. The lengths of the bottom and side templates may or may not be the same. Adjacent bottom and side templates are assembled using C-grooves and pins. However, this assembly structure results in time-consuming and labor-intensive assembly for workers, leading to low construction efficiency.

[0076] To address the problem of time-consuming and labor-intensive assembly and low construction efficiency caused by the use of formwork connecting the internal corners of window openings in related technologies, the first aspect is to refer to... Figure 1 One embodiment of this application provides a window opening corner connection template, including two window opening bottom templates 100, window opening side templates 200, and four L-shaped connectors 300. The window opening bottom template 100 includes a first template body. The window opening side templates 200 are arranged adjacent to the window opening bottom template 100. The window opening side templates 200 include a second template body. The L-shaped connectors 300 are integrated into both ends of the first template body; or, integrated into both ends of the second template body; or, integrated into one end of the first template body and one end of the second template body.

[0077] The lengths of the first and second formwork bodies can be equal or unequal, and the specific lengths can be determined based on the size of the window openings at the construction site. The first and second formwork bodies are adjacent to and perpendicular to each other. L-shaped connectors 300 are placed at the inside corners of the window openings to connect the adjacent formwork bodies.

[0078] Specifically, after the first template body and the second template body are sequentially spliced ​​together, the four L-shaped connectors 300 are located at the four inside corners of the window opening. There are three possible arrangements: one L-shaped connector 300 is set at each end of the two first template bodies, one L-shaped connector 300 is set at each end of the two second template bodies, or one L-shaped connector 300 is set at one end of the two first template bodies and one end of the two second template bodies.

[0079] In this embodiment, the window opening inside corner connection template uses an integrated L-shaped connector 300 instead of the traditional C-groove connection, which helps to improve the assembly efficiency of the window opening inside corner connection template, thereby improving construction efficiency; at the same time, the L-shaped connector 300 helps to ensure the molding quality of the concrete at the window opening inside corner.

[0080] Reference Figure 1 In one embodiment, the L-shaped connector 300 includes an L-shaped connecting plate, the top of which protrudes from the top wall of the target component to which it is connected, and the top of the L-shaped connecting plate and the top wall of the target component enclose a notch 330.

[0081] The target component is connected to the L-shaped connecting plate and can be enclosed by the L-shaped connecting plate to form a notch 330. The L-shaped connecting plate includes a horizontal plate 310 and a vertical plate 320 arranged perpendicularly to each other, and the L-shaped connecting plate can be extruded by an extrusion process, that is, the horizontal plate 310 and the vertical plate 320 can be integrally formed. Since the L-shaped connecting plate needs to be set at the inside corner of the window opening and needs to cooperate with the adjacent template body, the top of the L-shaped connecting plate must protrude beyond the target component, that is, the height of the upper surface of the L-shaped connecting plate is higher than the height of the top wall of the target component, and the vertical plate 320 of the L-shaped connecting plate is connected to the target component, while the horizontal plate 310 of the L-shaped connecting plate protrudes beyond the target component and is opposite to the target component.

[0082] Reference Figure 1 and Figure 2 In one embodiment, the first template body includes a first panel 110, two first side plates 120, and two L-shaped connecting plates.

One end of the first side plate 120 is connected to one of the L-shaped connecting plates, and the other end of the first side plate 120 is connected to the other L-shaped connecting plate. The target component includes the first side plate 120.

The distance between the two first side panels 120 is less than the width of the first panel 110. The side wall of the bottom end of the L-shaped connecting plate is welded to the end of the first panel 110. The end wall of the first side panel 120 is welded to the vertical plate 320 of the L-shaped connecting plate. The horizontal plate 310 of the L-shaped connecting plate protrudes from the top wall of the first side panel 120.

The two first side plates 120 are both vertically connected to the upper surface of the first panel 110. The extrusion direction of the first side plates 120 is parallel to the extrusion direction of the first panel 110, and the end wall of the first side plates 120 is flush with the end wall of the first panel 110. The first L-shaped connecting plate is disposed at one end of the first panel 110, and one end of the first side plate 120 is connected to the first L-shaped connecting plate. The second inner sealing plate 130 is disposed at the other end of the first panel 110. The target component includes the first side plate 120.

[0095] Accordingly, the second template body includes a second panel 210, two second side plates 220, a second L-shaped connecting plate, and at least one first inner sealing plate 230. The two second side plates 220 are vertically connected to the upper surface of the second panel 210. The extrusion direction of the second side plates 220 is parallel to the extrusion direction of the second panel 210, and the end wall of the second side plates 220 is flush with the end wall of the second panel 210. The second L-shaped connecting plate is disposed at one end of the second panel 210, and one end of the second side plate 220 is connected to the second L-shaped connecting plate. The first inner sealing plate 230 is disposed at the other end of the second panel 210. The first inner sealing plate 230 is detachably connected to the first L-shaped connecting plate, and the second inner sealing plate 230 is detachably connected to the second L-shaped connecting plate. The target component also includes the second side plates 220.

[0096] In addition, pin holes 500 are provided through the horizontal plate 310, the first inner sealing plate 230, and the second inner sealing plate 130 of the L-shaped connecting plate to facilitate installation by workers.

[0097] Specifically, unlike the aforementioned embodiments, the first L-shaped connecting plate is disposed at either end of the first panel 110, and the second L-shaped connecting plate is disposed at either end of the second panel 210, that is, both the first template body and the second template body include L-shaped connecting plates.

[0098] In this embodiment, when assembling the window opening corner connection template, one of the first template bodies is first installed at the bottom of the window opening, and then one of the second template bodies is installed on the side of the window opening, so that the first L-shaped connecting plate is connected to the first inner sealing plate 230, or the second L-shaped connecting plate is connected to the second inner sealing plate 130, thereby realizing the assembly of two adjacent window opening bottom templates 100 and window opening side templates 200. In the same way, the other two adjacent window opening bottom templates 100 and window opening side templates 200 are assembled to obtain a complete window opening corner connection template.

[0099] Reference Figure 4In any of the above embodiments, one or two first template bodies, or one or two second template bodies, include two sub-template bodies and an early removal component 400, wherein the sub-template bodies contain at most one L-shaped connector 300; the early removal component 400 is detachably disposed between the two sub-template bodies.

[0100] In order to facilitate demolding after the pouring at the window opening, an early removal component 400 is set. The number of early removal components 400 can be one or two, but no more is needed, otherwise it will also cause low demolding efficiency.

[0101] Specifically, the early-release component 400 includes a third panel and four third peripheral side panels 410. The four third peripheral side panels 410 form a square frame. When the early-release component 400 is connected to the sub-template body of the first template body, the length of the third peripheral side panel 410 opposite to the sub-template body of the first template body is the same as the length of the second inner sealing plate 130, and the height of the third peripheral side panel 410 is also the same as the height of the second inner sealing plate 130. The positions of the pin holes 500 also correspond. When the early-release component 400 is connected to the sub-template body of the second template body, the length of the third peripheral side panel 410 opposite to the sub-template body of the second template body is the same as the length of the first inner sealing plate 230, and the height of the third peripheral side panel 410 is also the same as the height of the first inner sealing plate 230. The positions of the pin holes 500 also correspond.

[0102] In this embodiment, the early demolding component 400 allows workers to quickly demold after pouring concrete at the window opening, thereby improving construction efficiency.

[0103] The window opening corner connection template in this application uses an integrated L-shaped connector 300 instead of the traditional C-groove connection, which helps to improve the assembly efficiency of the window opening corner connection template, thereby improving construction efficiency. At the same time, the L-shaped connector 300 helps to ensure the molding quality of the concrete at the window opening corner. In addition, the early stripping part 400 makes it easier for workers to demold later, thus helping to improve construction efficiency.

[0104] In addition, the window opening corner connection template of this application can be applied to, for example...

Through integrated design, the original inside corner formwork is combined with the aluminum alloy flat formwork to realize the connection of the formwork at the inside corner between the concrete structure wall and the beam.

[0109] The window openings in the wall template 7 are connected by the window opening inside corner connecting template 5. In the existing wall, many exterior walls need to have window openings. The window opening inside corner connecting template 5 is connected to the wall template 7 on all four sides to reserve the position of the window opening. The window opening inside corner connecting template 5 is designed in an integrated manner to combine the original inside corner template with the aluminum alloy flat template, so as to realize the connection of the template at the inside corner between the concrete structure wall and the window opening.
