Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a formwork device and a formwork system. Background Art

[0002] Building formwork is widely used in construction due to its advantages such as reusability, high strength and easy installation. At the same time, back ribs are set on the non-casting surface of the formwork to increase the rigidity of the formwork to prevent deformation or displacement during the concrete pouring process.

[0003] However, the existing formwork and back ribs are mainly suitable for standard 90° corners. If you need to cast walls with corners at other angles, such as obtuse or acute angles, you will need to customize the formwork and back ribs. Summary of the invention

[0004] In view of this, the present application provides a template device and a template system, which can be adjusted according to different corner angles.

[0005] An embodiment of the present application provides a template device, including a template mechanism and a back-rib mechanism. The template mechanism includes a first template and a second template. The back-rib mechanism includes a first back rib and a second back rib. The first template and the second template are rotatably connected so that the angle formed between the first template and the second template is adjustable. The first back rib and the second back rib are detachably connected, and the first back rib is configured to be rotatable relative to the second back rib. The back-rib mechanism also includes a back-rib support. The back-rib support is arranged between the first back rib and the second back rib to provide support for the first back rib and the second back rib. The back-rib support is configured to be retractable so that the angle formed between the first back rib and the second back rib is adjustable. The template device also includes an intermediate connector. The intermediate connector connects the back-rib mechanism and the template mechanism.

[0006] In the above embodiment, the first template and the second template of the template mechanism are rotatably connected, and the angle between the first template and the second template can be adjusted according to the actual angle requirements, which is conducive to the template mechanism being suitable for casting more corners with different angles; the first back rib and the second back rib of the back rib mechanism are also rotatably connected, and a retractable back rib support is arranged between the first back rib and the second back rib to provide support for the first back rib and the second back rib with adjustable angles, and finally the back rib mechanism and the template mechanism are connected with an intermediate connecting member to form an angle-adjustable template device, and then concrete pouring is carried out. The template mechanism helps to form the corner, and the back rib mechanism can increase the rigidity of the template mechanism to avoid deformation or displacement of the template mechanism during the concrete pouring and forming process; the entire template device can meet the requirements of multiple different corner angles.

[0007] In some embodiments of the present application, the template mechanism further includes a corner connection component and a first connection plate. The corner connection component is detachably connected to the first template. The corner connection component is detachably connected to the second template so that the first template and the second template are rotatably connected. The first connection plate is detachably connected to the first template. The first connection plate is detachably connected to the second template and blocks the gap between the first template and the second template.

[0008] In the above embodiment, when the first template and the second template are rotated through the corner connection assembly, the two may separate from each other and form a gap. By setting the first connection plate, the gap between the first template and the second template can be blocked, which is beneficial to prevent the flowing concrete slurry from leaking from between the first template and the second template, thereby ensuring the pouring quality at the corner. At the same time, the first template, the second template and the corner connection assembly, as well as the first template, the second template and the first connection plate, are all detachably connected. The first template, the second template and the corner connection assembly can be used as universal parts. Only the first connection plate that matches the actual angle needs to be connected to relatively fix the first template and the second template at the required corner angle. The entire template mechanism is flexible to assemble and disassemble, ensuring that it can meet the needs of multiple different angles.

[0009] In some embodiments of the present application, the template mechanism further includes a second connecting plate. The second connecting plate is detachably connected to a side of the first template facing away from the first connecting plate, and is detachably connected to a side of the second template facing away from the first connecting plate. The first back rib is connected to the first template at a position avoiding the second connecting plate. The second back rib is connected to the second template at a position avoiding the second connecting plate.

[0010] In the above embodiment, a second connecting plate is arranged on the side of the first template away from the first connecting plate, and the second connecting plate together with the first connecting plate are respectively located on two opposite surfaces of the first template and the second template, forming a "clamping" effect, so that it can not only stop in "forward rotation" but also stop in "reverse rotation", which can effectively prevent the template mechanism from displacement or deformation during concrete pouring, thereby improving the stability of the template mechanism. When the back rib mechanism and the template mechanism are connected, since the side where the second connecting plate is located is the non-casting side of the template mechanism, when the second connecting plate is detachably connected to the first template and the second template, the fasteners for detachable connection are usually arranged on the side of the second connecting plate away from the first connecting plate, so the first back rib and the second back rib need to avoid the position of the second connecting plate to avoid interference.

[0011] In some embodiments of the present application, the corner connection assembly includes two corner connectors. Each corner connector includes a connection portion and a corner rotation portion. The connection portion of one corner connector is detachably connected to the first template, the connection portion of the other corner connector is detachably connected to the second template, and the corner rotation portions of the two corner connectors are rotatably connected.

[0012] In the above embodiment, the corner connection assembly is composed of two corner connectors, each corner connector is composed of a connecting portion and a corner rotating portion, the corner rotating portions of the two corner connectors are rotatably connected, and the connecting portion of each corner connector is detachably connected to the first template or the second template, thereby achieving an adjustable angle between the first template and the second template; the corner connector designed in this way is a standard part, which is convenient for assembly, disassembly and storage.

[0013] In some embodiments of the present application, the first template includes a first base plate and a first side rib. The first side rib is vertically connected to the edge of the first base plate. The second template includes a second base plate and a second side rib. The second side rib is vertically connected to the edge of the second base plate. The connecting portion of one corner connector is detachably connected to the first side rib. The connecting portion of another corner connector is detachably connected to the second side rib.

[0014] In the above embodiment, compared with the two connecting parts being connected to the plate surfaces of the first template and the second template (i.e., the first bottom plate and the second bottom plate), the two connecting parts are arranged on the first side rib and the second side rib, which is conducive to setting the first template and the second template at a distance, thereby providing sufficient operating space for the rotation of the first template and the second template, reducing the possibility of the first template and the second template interfering with each other and hindering the rotation, and facilitating the user to flexibly install or adjust. And if the corner connection assembly is assembled with the first bottom plate and the second bottom plate respectively, it is possible to open corresponding assembly holes on the first bottom plate and the second bottom plate, so that during the pouring process, the flowing concrete slurry may penetrate into the interior of each corner connector, causing the corner connector to get stuck or difficult to disassemble.

[0015] In some embodiments of the present application, the first back rib has a first connection portion and a first matching portion. The second back rib has a second connection portion and a second matching portion. The back rib support has a third connection portion and a fourth connection portion. The third connection portion and the first back rib are detachably connected, and the fourth connection portion and the second back rib are detachably connected. When the template device is installed at the inner corner, the first connection portion and the second connection portion are connected, the third connection portion and the first matching portion are connected, and the fourth connection portion and the second matching portion are connected. When the template device is installed at the outer corner, the first connection portion and the second matching portion are connected, the third connection portion and the first matching portion are connected, and the fourth connection portion and the second connection portion are connected. The back rib support is configured so that the distance between the third connection portion and the fourth connection portion is adjustable, so that the angle formed between the first back rib and the second back rib is adjustable.

[0016] In the above embodiment, a first connection part and a first matching part are provided on the first back rib, a second connection part and a second matching part are provided on the second back rib, and the back rib support is configured so that the distance between the third connection part and the fourth connection part is adjustable. When the back rib mechanism is installed at the inner corner, the first connection part of the first back rib is connected to the second connection part of the second back rib, the third connection part of the back rib support is connected to the first matching part of the first back rib, and the fourth connection part of the back rib support is connected to the second matching part of the second back rib. When the back rib mechanism is installed at the outer corner, the first connection part of the first back rib is connected to the second matching part of the second back rib, the third connection part of the back rib support is connected to the first matching part of the first back rib, and the fourth connection part of the back rib support is connected to the second connection part of the second back rib. In this way, by replacing the connection positions among the first back rib, the second back rib, and the back rib support, one back rib mechanism can be adapted to the inner corners and outer corners of different turning angles.

[0017] In some embodiments of the present application, the back-ribbed mechanism further includes a connecting assembly. The connecting assembly includes two connecting members, each of which includes a connecting rotating portion and a mounting portion. One connecting member is a first connecting member, and the other connecting member is a second connecting member. The mounting portion of the first connecting member and the first matching portion are detachably connected. The mounting portion and the second matching portion of the second connecting member are detachably connected. When the template device is installed at a female corner, the third connecting portion and the connecting rotating portion of the first connecting member are rotatably connected, and the fourth connecting portion and the connecting rotating portion of the second connecting member are rotatably connected. When the template device is installed at a male corner, the first connecting portion and the connecting rotating portion of the second connecting member are rotatably connected, and the third connecting portion and the connecting rotating portion of the first connecting member are rotatably connected.

[0018] In the above embodiment, a connection assembly including two connecting parts is designed, which are respectively used for the assembly and disassembly between the back rib support and the first back rib and the second back rib. The use of a unified connecting part also facilitates storage. Each connecting part includes a connecting rotating part and a mounting part. The mounting part is used to connect the connecting part and the first back rib and the second back rib, and the connecting rotating part is connected to the third connecting part and the fourth connecting part of the back rib support. In this way, when the turning angle changes, the distance between the third connecting part and the fourth connecting part is adjusted. If the back rib mechanism is installed at the inner corner, the third connecting part and the fourth connecting part can respectively realize the rotation of the back rib support relative to the first back rib and the second back rib through the connecting rotating part of the first connecting part and the connecting rotating part of the second connecting part to adapt to the change of the turning angle; when the back rib mechanism is installed at the outer corner, the same is true. The back rib support can be rotated relative to the first back rib through the connecting rotating part of the first connecting part, and the first back rib can be rotated relative to the second back rib by the connecting rotating part of the second connecting part.

[0019] In some embodiments of the present application, the first matching portion has a first supporting surface and a second supporting surface. The first supporting surface and the second supporting surface are arranged opposite to each other. The second matching portion has a third supporting surface and a fourth supporting surface. The third supporting surface and the fourth supporting surface are arranged opposite to each other. When the template device is installed at the internal angle, the second supporting surface and the side opposite to the casting surface of the first template are arranged opposite to each other. The fourth supporting surface and the side opposite to the casting surface of the second template are arranged opposite to each other. The mounting portion of the first connecting member is connected to the first supporting surface. The mounting portion of the second connecting member is connected to the third supporting surface. When the template device is installed at the external angle, the first supporting surface and the side opposite to the casting surface of the first template are arranged opposite to each other. The third supporting surface and the side opposite to the casting surface of the second template are arranged opposite to each other. The mounting portion of the first connecting member is connected to the second supporting surface. The mounting portion of the second connecting member is connected to the third supporting surface.

[0020] In the above embodiment, the supporting surfaces on the first matching part and the second matching part are attached to or opposite to the wall surface or the side opposite to the casting surface of the template according to the actual installation situation (internal corner, external corner). When the back-rib mechanism is installed in the internal corner, the first supporting surface and the third supporting surface are supported by the back-rib support member, and when the back-rib mechanism is installed in the external corner, the second supporting surface and the third supporting surface are supported, ensuring that the supporting force provided by the back-rib support member can be effectively transmitted to the first back rib and the second back rib.

[0021] In some embodiments of the present application, a first connecting groove is provided on the first supporting surface at a position corresponding to the first matching portion. A second connecting groove is provided on the second supporting surface at a position corresponding to the first matching portion. A third connecting groove is provided on the third supporting surface at a position corresponding to the second matching portion. When the template device is installed at a female corner, the mounting portion of the first connecting member is located in the first connecting groove, and the mounting portion of the second connecting member is located in the third connecting groove. When the template device is installed at a male corner, the mounting portion of the first connecting member is located in the second connecting groove, and the mounting portion of the second connecting member is located in the third connecting groove.

[0022] In the above embodiment, connecting grooves are provided on the first supporting surface, the second supporting surface and the third supporting surface at positions corresponding to the respective matching parts, so that the mounting parts of the respective connecting parts can be located correspondingly in the connecting grooves, and the connection strength between the respective connecting parts and the first back ribs and the second back ribs is more stable and reliable.

[0023] An embodiment of the present application provides a template system, including two template devices, one template device is installed at the inner corner, and the other template device is installed at the outer corner.

[0024] In the above embodiment, the two formwork devices are adjusted to adjust the formwork mechanisms and the back-rib mechanisms according to the preset corner angles, one formwork device is set at the inner corner, and the other formwork mechanism is set at the outer corner, and then the corner wall is cast. The formwork mechanism and the back-rib mechanism can be adjusted according to the actual corner angle requirements to meet the requirements of different angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When an element is considered to be "set on" another element, it may be directly set on the other element or there may be a central element at the same time.

[0032] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0034] An embodiment of the present application provides a template device, including a template mechanism and a back-rib mechanism. The template mechanism includes a first template and a second template. The back-rib mechanism includes a first back rib and a second back rib. The first template and the second template are rotatably connected so that the angle formed between the first template and the second template is adjustable. The first back rib and the second back rib are detachably connected, and the first back rib is configured to be rotatable relative to the second back rib. The back-rib mechanism also includes a back-rib support. The back-rib support is arranged between the first back rib and the second back rib to provide support for the first back rib and the second back rib. The back-rib support is configured to be retractable so that the angle formed between the first back rib and the second back rib is adjustable. The template device also includes an intermediate connector. The intermediate connector connects the back-rib mechanism and the template mechanism.

[0035] The first template and the second template of the template mechanism are rotatably connected, and the angle between the first template and the second template can be adjusted according to the actual angle requirements, which is conducive to the template mechanism being suitable for casting more corners with different angles; the first back rib and the second back rib of the back rib mechanism are also rotatably connected, and a retractable back rib support is arranged between the first back rib and the second back rib to provide support for the first back rib and the second back rib with adjustable angles, and finally the back rib mechanism and the template mechanism are connected with an intermediate connecting member to form an angle-adjustable template device, and then concrete is poured. The template mechanism helps to form the corner, and the back rib mechanism can increase the rigidity of the template mechanism to avoid deformation or displacement of the template mechanism during the concrete pouring and forming process; the entire template device can meet the needs of multiple different corner angles.

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] See also Figure 1 and Figure 2 , an embodiment of the present application provides a template device 300, including a template mechanism 100 and a back-rib mechanism 200. The template mechanism 100 includes a first template 1 and a second template 2. The back-rib mechanism 200 includes a first back rib 6 and a second back rib 7. The first template 1 and the second template 2 are rotatably connected to make the angle formed between the first template 1 and the second template 2 adjustable. The first back rib 6 and the second back rib 7 are detachably connected, and the first back rib 6 is configured to be rotatable relative to the second back rib 7. The back-rib mechanism 200 also includes a back-rib support 8. The back-rib support 8 is arranged between the first back rib 6 and the second back rib 7 to provide support for the first back rib 6 and the second back rib 7. The back-rib support 8 is configured to be retractable to make the angle formed between the first back rib 6 and the second back rib 7 adjustable. The template device 300 also includes a tension bolt 3001. The tension bolt 3001 connects the back-rib mechanism 200 and the template mechanism 100.

[0038] The first template 1 and the second template 2 of the template mechanism 100 are rotatably connected, and the angle between the first template 1 and the second template 2 can be adjusted according to the actual angle requirements, which is conducive to the template mechanism 100 being suitable for casting more corners with different angles; the first back rib 6 and the second back rib 7 of the back rib mechanism 200 are also rotatably connected, and a retractable back rib support 8 is arranged between the first back rib 6 and the second back rib 7 to provide support for the first back rib 6 and the second back rib 7 with adjustable angles, and finally the back rib mechanism 200 and the template mechanism 100 are connected with tension bolts 3001 to form an angle-adjustable template device 300, and then concrete is poured. The template mechanism 100 helps to form the corner, and the back rib mechanism 200 can increase the rigidity of the template mechanism 100 to avoid deformation or displacement of the template mechanism 100 during the concrete pouring and forming process; the entire template device 300 can meet the requirements of multiple different corner angles.

[0039] See also Figure 2 and Figure 3 In some embodiments, the template mechanism 100 further includes a corner connection component 3 and a first connection plate 41. The corner connection component 3 is detachably connected to the first template 1. The corner connection component 3 is detachably connected to the second template 2 so that the first template 1 and the second template 2 are rotatably connected. The first connection plate 41 is detachably connected to the first template 1. The first connection plate 41 is detachably connected to the second template 2 and blocks the gap between the first template 1 and the second template 2.

[0040] When the first template 1 and the second template 2 are rotated through the corner connection assembly 3, the two may separate from each other and form a gap. By setting the first connection plate 41, the gap between the first template 1 and the second template 2 can be blocked, which is beneficial to prevent the flowing concrete slurry from leaking from between the first template 1 and the second template 2, thereby ensuring the pouring quality at the corner. At the same time, the first template 1, the second template 2 and the corner connection assembly 3, as well as the first template 1, the second template 2 and the first connection plate 41, are all detachably connected. The first template 1, the second template 2 and the corner connection assembly 3 can be used as universal parts. Only the first connection plate 41 that matches the actual angle needs to be connected to make the first template 1 and the second template 2 relatively fixed at the required corner angle. The entire template mechanism 100 is flexible to assemble and disassemble, ensuring that it can meet the needs of multiple different angles.

[0041] In some embodiments, the template mechanism 100 further includes a second connecting plate 42. The second connecting plate 42 is detachably connected to the side of the first template 1 that is away from the first connecting plate 41, and is detachably connected to the side of the second template 2 that is away from the first connecting plate 41, so that the first template 1 and the second template 2 are fixed. The first back rib 6 is connected to the first template 1 at a position avoiding the second connecting plate 42, so that in a direction perpendicular to the first casting surface 111, the projections of the first back rib 6 and the second connecting plate 42 do not overlap; the second back rib 7 is connected to the second template 2 at a position avoiding the second connecting plate 42; so that in a direction perpendicular to the second casting surface 211, the projections of the second back rib 7 and the second connecting plate 42 do not overlap.

[0042] A second connecting plate 42 is arranged on the side of the first template 1 away from the first connecting plate 41. The second connecting plate 42 and the first connecting plate 41 are respectively located on the two opposite surfaces of the first template 1 and the second template 2, forming a "clamping" effect, so that it can not only stop in "forward rotation" but also stop in "reverse rotation", which can effectively prevent the template mechanism 100 from displacement or deformation during concrete pouring, thereby improving the stability of the template mechanism 100. When the back rib mechanism 200 and the template mechanism 100 are connected, since the side where the second connecting plate 42 is located is the non-pouring side of the template mechanism 100, when the second connecting plate 42 is detachably connected to the first template 1 and the second template 2, the fasteners for detachable connection are usually arranged on the side of the second connecting plate 42 away from the first connecting plate 41, so the first back rib 6 and the second back rib 7 need to avoid the position of the second connecting plate 42 to avoid interference.

[0043] In some embodiments, the first connecting plate 41 can be formed by bending an alloy plate and processed according to the actual angle requirements. Of course, welding or casting can also be used. Bending is more convenient and has lower costs. For corners of different angles, only the first connecting plate 41 needs to be replaced, which can flexibly adapt to all angle requirements and reduce manufacturing costs. Figure 3 and Figure 4 , which are applicable to the cases where the corner angle is obtuse and acute respectively.

[0044] In some embodiments, the second connecting plate 42 can be formed by bending an alloy plate, or by welding, splicing, or casting.

[0045] In some embodiments, the corner connection assembly 3 includes two corner connectors 31. Each corner connector 31 includes a connection portion 301 and a corner rotation portion 302. The connection portion 301 of one corner connector 31 is detachably connected to the first template 1, the connection portion 301 of the other corner connector 31 is detachably connected to the second template 2, and the corner rotation portions 302 of the two corner connectors 31 are rotatably connected.

[0046] The corner rotating portion 302 of each corner connector 31 can be rotatably matched with the corner rotating portion 302 of another corner connector 31, and the connecting portion 301 of each corner connector 31 can be connected to the first template 1 or the second template 2, so that the separated first template 1 and the second template 2 can be assembled into a rotational connection through two corner connectors 31. The corner connector 31 can be detachably connected to the first template 1 or the second template 2, and when assembling the template mechanism 100, there is no need to deliberately seek a component that is compatible with the first template 1 or the second template 2, so that each corner connector 31 can be used as a standard component for general use, thereby facilitating the assembly, disassembly and storage of the template mechanism 100.

[0047] In some embodiments, the first template 1 includes a first bottom plate 11 and a first side rib 12. The first side rib 12 is vertically connected to the edge of the first bottom plate 11. The second template 2 includes a second bottom plate 21 and a second side rib 22. The second side rib 22 is vertically connected to the edge of the second bottom plate 21. The connecting portion 301 of one corner connector 31 is detachably connected to the first side rib 12. The connecting portion 301 of another corner connector 31 is detachably connected to the second side rib 22.

[0048] Compared with the two connecting parts 301 connected to the plate surface of the first template 1 and the second template 2 (i.e., the first bottom plate 11 and the second bottom plate 21), setting the two connecting parts 301 on the first side rib 12 and the second side rib 22 is conducive to setting the first template 1 and the second template 2 at a distance, thereby providing sufficient operating space for the rotation of the first template 1 and the second template 2, reducing the possibility of the first template 1 and the second template 2 interfering with each other and hindering the rotation, and facilitating the user to flexibly install or adjust. And if the corner connection component 3 is assembled with the first bottom plate 11 and the second bottom plate 21 respectively, it is possible to open corresponding assembly holes on the first bottom plate 11 and the second bottom plate 21, so that during the pouring process, the flowing concrete slurry may penetrate into each corner connector 31, causing the corner connector 31 to get stuck or difficult to disassemble.

[0049] In some embodiments, see Figure 6 The first side rib 12 and the second side rib 22 are also provided with a plurality of first connection holes 121 and second connection holes 221 for connecting the first template 1 and the second template 2. The connection portion 301 of the corner connector 31 can be installed in the first connection hole 121 and the second connection hole 221 for installation without the need for additional holes.

[0050] See also Figure 6 In some embodiments, the connecting portion 301 is a plate-like structure, the corner rotating portion 302 is a plate-like structure, and the connecting portion 301 and the corner rotating portion 302 are perpendicular to each other.

[0051] The connecting part 301 and the corner rotating part 302 are both designed to be plate-like structures, and can be directly manufactured using existing template materials. At the same time, based on the fact that the first side rib 12 is perpendicular to the first bottom plate 11 and the second side rib 22 is perpendicular to the second bottom plate 21, and the rotation axis direction of the two corner connecting parts 31 is the axis direction of the rotation of the first template 1 and the second template 2, the connecting part 301 and the corner rotating part 302 are designed to be perpendicular to each other, and the connecting part 301 can be selected to cooperate with the first template 1 or the second template 2, so as to flexibly adjust the angle between the first template 1 and the second template 2.

[0052] In some embodiments, the connection portion 301 of one corner connector 31 and the connection portion 301 of another corner connector 31 are arranged in opposite directions (ie, Figure 6 The vertical staggered arrangement shown in the figure can optimize the force transmission path so that the force received by the entire corner connection assembly 3 in the direction perpendicular to its rotation axis is balanced. Further, when each first connection hole 121 corresponds to each second connection hole 221, the corner connection members 31 used as standard parts need to be arranged in opposite directions so as not to interfere with each other.

[0053] See also Figure 5 In some embodiments, an edge of the corner rotating portion 302 away from the connecting portion 301 is arc-shaped.

[0054] The edge of the corner rotating part 302 of the plate-like structure away from the connecting part 301 is designed to be arc-shaped to avoid interference between the two corner connectors 31 when adjusting, so that the angle can be flexibly adjusted to meet the needs of corner casting at any angle. The arc surface can reduce the distance between the corner rotating part 302 and the opposite side when rotating, thereby helping to reduce the gap between the first template 1 and the second template 2.

[0055] See also Figure 3 and Figure 5 In some embodiments, the first bottom plate 11 has a first casting surface 111 , and the second bottom plate 21 has a second casting surface 211 . The first casting surface 111 and the second casting surface 211 are respectively disposed in contact with the first connecting plate 41 .

[0056] The first connecting plate 41 is arranged on the surface where the first bottom plate 11 and the second bottom plate 21 are in contact with the corner wall, ensuring that the surface of the first connecting plate 41 that is away from the first casting surface 111 and / or the second casting surface 211 serves as the casting surface in contact with the corner. The first connecting plate 41 only needs to be designed according to the corner angle or shape, thereby improving the applicability of the entire formwork mechanism 100.

[0057] exist Figure 3 and Figure 4In each of the embodiments shown, the first connecting plate 41 is designed to adapt to a sharp corner structure. Of course, the first connecting plate 41 can also be bent into a structure with an arc in the middle to meet the requirement of an arc at the corner of the wall.

[0058] See also Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the first casting surface 111 includes a first facet 1111 and a second facet 1112, the first facet 1111 is closer to the second casting surface 211 than the second facet 1112, and there is a height difference between the first facet 1111 and the second facet 1112, the second casting surface 211 includes a third facet 2111 and a fourth facet 2112, the third facet 2111 is closer to the first casting surface 111 than the fourth facet 2112, and there is a height difference between the third facet 2111 and the fourth facet 2112, the first connecting plate 41 has a third casting surface 411, and the first connecting plate 41 is connected to the first facet 1111 and the third facet 2111. In some embodiments, the second facet 1112 and the fourth facet 2112 are flush with the third casting surface 411, respectively.

[0059] Since the first casting surface 111 and the second casting surface 211 are respectively arranged in contact with the first connecting plate 41, the first casting surface 111 is further designed to be a first facet 1111 and a second facet 1112 with a height difference, and the second casting surface 211 is designed to be a third facet 2111 and a fourth facet 2112 with a height difference, and then the first connecting plate 41 is respectively connected to the first facet 1111 and the third facet 2111, which helps to reduce the height difference between the third casting surface 411 of the first connecting plate 41 and the second facet 1112 and the fourth facet 2112, thereby improving the flatness of the corner wall after casting and avoiding the wall from misalignment. Here, the height difference refers to the dimension along the thickness direction of the first template 1 and the second template 2. Furthermore, the second facet 1112 and the fourth facet 2112 are respectively flush with the third casting surface 411, which can further improve the flatness of the corner wall after casting.

[0060] In some embodiments, the first connecting plate 41, the first template 1, the second template 2 and the second connecting plate 42 are connected as a whole using a round head bolt 1001, and the head of the round head bolt 1001 is arranged on one side of the third casting surface 411 of the first connecting plate 41; compared with the general hexagonal bolt, the head of the round head bolt 1001 is flatter, so that the casting surface is smoother and the casting effect is better.

[0061] See also Figure 8In some embodiments, the template mechanism 100 also includes a first support member 51 and a second support member 52, the first support member 51 is connected to the side of the second connecting plate 42 facing the first template 1 and abuts against the first template 1, and the second support member 52 is connected to the side of the second connecting plate 42 facing the second template 2 and abuts against the second template 2.

[0062] The corner connection assembly 3 is arranged on the side ribs of the first template 1 and the second template 2, and the first support member 51 and the second support member 52 are respectively arranged on the second connecting plate 42 facing the first template 1 and the second template 2 to provide support for the first panel and the second panel. Such an arrangement can improve the structural strength and stability of the entire template mechanism 100.

[0063] In some embodiments, the first support member 51, the second support member 52 and the second connecting plate 42 are integrally formed to reduce assembly and disassembly steps. In other embodiments, the first support member 51, the second support member 52 and the second connecting plate 42 are split structures to facilitate storage.

[0064] In some embodiments, the first support member 51 and the second support member 52 are both tubular structures, and common round steel pipes can be used. Appropriate lengths can be cut and welded to the second connecting plate 42. In order to further improve the support strength, a plurality of first support members 51 and second support members 52 connected to a second connecting plate 42 can be provided. Since circular holes for detachable connection are also provided on the second connecting plate 425 during implementation, these circular holes are coaxially arranged corresponding to the first support members 51 and the second support members 52. However, in order to ensure that the template mechanism 100 can adapt to any angle, such as Fig. 9 As shown, when the angle between the first template 1 and the second template 2 is small, the bolts (or other detachable connectors 91) used to connect the second connecting plate 42 to the first template 1 will interfere with the bolts connecting the second connecting plate 42 to the second template 2. Therefore, the first support member 51 and the second support member 52 connected to the second connecting plate 42 should be staggered left and right with respect to the rotation axis direction of the first template 1 and the second template 2, so as to further ensure that the template mechanism 100 can flexibly adjust the angle.

[0065] See also Figures 9 to 11 In some embodiments, a plurality of second connecting plates 42 are provided, and the plurality of second connecting plates 42 are distributed along the axis of rotation of the first template 1 and the second template 2 .

[0066] Since the second connecting plate 42 is arranged on the side of the first template 1 away from the first connecting plate 41 and does not have a casting surface, the second connecting plate 42 is designed to be multiple. Compared with the structure using a whole plate body, this not only ensures the structural strength, but also facilitates assembly and disassembly, and can effectively save materials and reduce costs.

The second back rib 7 has a second connection portion 701 and a second matching portion 702. The back rib support member 8 has a third connection portion 801 and a fourth connection portion 802. The third connection portion 801 and the first back rib 6 are detachably connected, and the fourth connection portion 802 and the second back rib 7 are detachably connected. When the template device 300 is installed at the inner corner, the first connection portion 601 and the second connection portion 701 are connected, the third connection portion 801 and the first matching portion 602 are connected, and the fourth connection portion 802 and the second matching portion 702 are connected. When the template device 300 is installed at the outer corner, the first connection portion 601 and the second matching portion 702 are connected, the third connection portion 801 and the first matching portion 602 are connected, and the fourth connection portion 802 and the second connection portion 701 are connected. The back rib support member 8 is configured so that the distance between the third connection portion 801 and the fourth connection portion 802 is adjustable, so that the angle formed between the first back rib 6 and the second back rib 7 is adjustable.

[0069] A first connection part 601 and a first matching part 602 are provided on the first back rib 6, a second connection part 701 and a second matching part 702 are provided on the second back rib 7, and the back rib support 8 is configured so that the distance between the third connection part 801 and the fourth connection part 802 is adjustable. When the back rib mechanism 200 is installed at a negative angle, the first connection part 601 of the first back rib 6 is connected to the second connection part 701 of the second back rib 7, the third connection part 801 of the back rib support 8 is connected to the first matching part 602 of the first back rib 6, and the fourth connection part 802 of the back rib support 8 is connected to the second matching part 702 of the second back rib 7. When the back rib mechanism 200 is installed at a positive angle, the first connection part 601 of the first back rib 6 is connected to the second matching part 702 of the second back rib 7, the third connection part 801 of the back rib support 8 is connected to the first matching part 602 of the first back rib 6, and the fourth connection part 802 of the back rib support 8 is connected to the second connection part 701 of the second back rib 7. In this way, by replacing the connection positions among the first back rib 6, the second back rib 7 and the back rib support 8, it is possible to realize that one back rib mechanism 200 can adapt to the inner and outer corners of different turning angles.

[0070] In some embodiments, see Fig.12 , the back-ribbed mechanism 200 also includes a connecting assembly 9. The connecting assembly 9 includes two connecting members 91, each of which includes a connecting rotating portion 911 and a mounting portion 912. One connecting member 91 is a first connecting member 901, and the other connecting member 91 is a second connecting member 902. The mounting portion 912 of the first connecting member 901 and the first matching portion 602 are detachably connected. The mounting portion 912 of the second connecting member 902 and the second matching portion 702 are detachably connected. When the template device 300 is installed at the inner corner, the third connecting portion 801 and the connecting rotating portion 911 of the first connecting member 901 are rotatably connected, and the fourth connecting portion 802 and the connecting rotating portion 911 of the second connecting member 902 are rotatably connected. When the template device 300 is installed at the outer corner, the first connecting portion 601 and the connecting rotating portion 911 of the second connecting member 902 are rotatably connected, and the third connecting portion 801 and the connecting rotating portion 911 of the first connecting member 901 are rotatably connected.

[0071] A connection assembly 9 including two connection pieces 91 is designed, which are used for assembly and disassembly between the back rib support piece 8 and the first back rib 6 and the second back rib 7 respectively. The use of a unified connection piece 91 also facilitates storage. Each connecting member 91 includes a connecting rotating portion 911 and a mounting portion 912. The mounting portion 912 is used to connect the connecting member 91 and the first back rib 6 and the second back rib 7. The connecting rotating portion 911 is connected to the third connecting portion 801 and the fourth connecting portion 802 of the back rib support member 8. In this way, when the turning angle changes, the distance between the third connecting portion 801 and the fourth connecting portion 802 is adjusted. If the back rib mechanism 200 is installed in the inner corner, the third connecting portion 801 and the fourth connecting portion 802 can respectively realize the rotation of the back rib support member 8 relative to the first back rib 6 and the second back rib 7 through the connecting rotating portion 911 of the first connecting member 901 and the connecting rotating portion 911 of the second connecting member 902 to adapt to the change of the turning angle; when the back rib mechanism 200 is installed in the outer corner, the back rib support member 8 can be rotated relative to the first back rib 6 through the connecting rotating portion 911 of the first connecting member 901, and the first back rib 6 can be rotated relative to the second back rib 7 through the connecting rotating portion 911 of the second connecting member 902.

[0072] In some embodiments, the plurality of first matching portions 602 are spaced apart and distributed in a direction away from the first connecting portion 601. The mounting portion 912 of the first connecting member 901 is connected to any first matching portion 602.

[0073] The plurality of second matching portions 702 are spaced apart from each other in a direction away from the second connecting portion 701. The mounting portion 912 of the second connecting member 902 is connected to any second matching portion 702.

[0074] The first matching portion 602 and the second matching portion 702 are arranged in plurality, and the position of the connecting member 91 can be adjusted according to the actual installation size requirements to ensure that the back rib support member 8 can provide effective supporting force for the first back rib 6 and the second back rib 7 .

[0075] In some embodiments, the connection assembly 9 further includes a fixing member 92. The mounting portion 912 of the first connection member 901 is fixed to the first matching portion 602 via the fixing member 92. The mounting portion 912 of the second connection member 902 is fixed to the second matching portion 702 via the fixing member 92.

[0076] A fixing member 92 is further designed because the installation position of the connecting member 91 on the first back rib 6 and the second back rib 7 can be adjusted according to actual conditions. When the installation positions of the first connecting member 901 and the second connecting member 902 are determined, the first connecting member 901 and the second connecting member 902 are fixed by the fixing member 92 to avoid relative movement between the first connecting member 901, the second connecting member 902 and the first back rib 6 and the second back rib 7, so that the structure of the entire back rib mechanism 200 is stable and reliable.

[0077] Please continue to see Figures 12 to 19 In some embodiments, the first matching portion 602 has a first supporting surface 6021 and a second supporting surface 6023. The first supporting surface 6021 and the second supporting surface 6023 are arranged opposite to each other. The second matching portion 702 has a third supporting surface 7021 and a fourth supporting surface 7023. The third supporting surface 7021 and the fourth supporting surface 7023 are arranged opposite to each other. When the template device 300 is installed at the inner corner, the second supporting surface 6023 is arranged opposite to the side of the casting surface of the first template 1. The fourth supporting surface 7023 is arranged opposite to the side of the casting surface of the second template 2. The mounting portion 912 of the first connecting member 901 is connected to the first supporting surface 6021. The mounting portion 912 of the second connecting member 902 is connected to the third supporting surface 7021. When the template device 300 is installed at the outer corner, the first supporting surface 6021 is arranged opposite to the side of the casting surface of the first template 1. The third supporting surface 7021 is arranged opposite to the side of the casting surface of the second template 2. The mounting portion 912 of the first connecting member 901 is connected to the second supporting surface 6023. The mounting portion 912 of the second connecting member 902 is connected to the third supporting surface 7021.

[0078] Each support surface on the first matching part 602 and the second matching part 702 is attached to or opposite to the wall surface or the side opposite to the casting surface of the template according to the actual installation situation (internal angle, external angle). When the back-rib mechanism 200 is installed at the internal angle, the first support surface 6021 and the third support surface 7021 receive the support force provided by the back-rib support member 8, and when the back-rib mechanism 200 is installed at the external angle, the second support surface 6023 and the third support surface 7021 receive the support force, ensuring that the support force provided by the back-rib support member 8 can be effectively transmitted to the first back rib 6 and the second back rib 7.

[0079] In some embodiments, a first connection groove 6022 is provided on the first support surface 6021 at a position corresponding to the first matching portion 602. A second connection groove 6024 is provided on the second support surface 6023 at a position corresponding to the first matching portion 602. A third connection groove 7022 is provided on the third support surface 7021 at a position corresponding to the second matching portion 702. When the template device 300 is installed at a female corner, the mounting portion 912 of the first connecting member 901 is located in the first connection groove 6022, and the mounting portion 912 of the second connecting member 902 is located in the third connection groove 7022.

[0080] Connecting grooves are provided on the first supporting surface 6021, the second supporting surface 6023 and the third supporting surface 7021 at positions corresponding to the mating parts, so that the mounting portion 912 of each connecting member 91 can be located in the connecting groove accordingly, and the connection strength between each connecting member 91 and the first back rib 6 and the second back rib 7 is more stable and reliable.

[0081] In some embodiments, each connecting member 91 further includes a stopper 913. The stopper 913 is located between the connecting portion 301 and the mounting portion 912.

[0082] When the back-rib mechanism 200 is installed in the internal corner, the stop portion 913 of the first connecting member 901 is in contact with the first supporting surface 6021 so that the mounting portion 912 of the first connecting member 901 reaches a preset depth when inserted into the first connecting groove 6022, and the stop portion 913 of the second connecting member 902 is in contact with the second supporting surface 6023 so that the mounting portion 912 of the second connecting member 902 reaches a preset depth when inserted into the third connecting groove 7022.

[0083] When the back-rib mechanism 200 is installed at the positive corner, the stop portion 913 of the first connecting member 901 is in contact with the third supporting surface 7021 so that the mounting portion 912 of the first connecting member 901 reaches a preset depth when inserted into the second connecting groove 6024, and the stop portion 913 of the second connecting member 902 is in contact with the second supporting surface 6023 so that the mounting portion 912 of the second connecting member 902 reaches a preset depth when inserted into the third connecting groove 7022.

[0084] A stopper 913 is further provided between the mounting portion 912 of the connector 91 and the connecting rotating portion 911, so that the mounting portion 912 of each connector 91 can accurately fall into the corresponding connecting groove by the stopper 913 of each connector 91 correspondingly contacting the supporting surface. See also Fig.13 , Fig.15 , Fig.17 , Fig.19 and Fig. 20 One embodiment of the present application provides a connection component 9, in which a fourth connection groove 7024 is provided on the fourth support surface 7023 at a position corresponding to the second matching portion 702. The first connection groove 6022 and the second connection groove 6024 of the first back rib 6 are connected to form a first through groove 603, and the third connection groove 7022 and the fourth connection groove 7024 of the second back rib 7 are connected to form a second through groove 703. Furthermore, on the first back rib 6, a plurality of first through grooves 603 of the first matching portions 602 are connected along the length direction of the first back rib 6; on the second back rib 7, a plurality of second through grooves 703 of the second matching portions 702 are connected along the length direction of the second back rib 7. Fig. 20As shown, the mounting portion 912 of the connector 91 is structured to match the first through slot 603 and the second through slot 703; at the same time, a plurality of slots 2001 arranged along the length direction of the first back rib 6 are provided on the surface between the first supporting surface 6021 and the second supporting surface 6023, and a plurality of slots 2001 arranged along the length direction of the second back rib 7 are provided on the surface between the third supporting surface 7021 and the fourth supporting surface 7023, and a limiting slot 9121 is provided on the mounting portion 912 of the connector 91.

[0085] When installing the connecting member 91 to the first back rib 6 and / or the second back rib 7, first insert the mounting portion 912 of the connecting member 91 into the first through groove 603 and / or the second through groove 703. The design of the stop portion 913 can ensure that the slot 2001 on the first matching portion 602 and / or the second matching portion 702 is aligned with the limiting groove 9121 on the mounting portion 912 of the connecting member 91, and can also prevent the connecting rotating portion 911 of the connecting member 91 from falling into the first through groove 603 and / or the second through groove 703. The fixing member 92 is designed to be a wedge-shaped pin piece 921. It is only necessary to insert the wedge-shaped pin piece 921 into the slot 2001 and the limiting groove 9121 to fix the connecting member 91 relative to the first back rib 6 and / or the second back rib 7. When the position of the connecting member 91 on the first back rib 6 and / or the second back rib 7 needs to be changed, the wedge-shaped pin piece 921 is removed without removing the connecting member 91, and the connecting member 91 is slid in the first through slot 603 and / or the second through slot 703 to the set position, and then the wedge-shaped pin piece 921 is inserted into the slot 2001 and the limiting slot 9121 for fixing. The operation is simple and the connection is reliable.

[0086] See also Figures 12 to 20 In some embodiments, the first connection portion 601 has a first arcuate edge 6011 extending around the circumference of the rotation axis of the first connection portion 601. The second connection portion 701 has a second arcuate edge 7011 extending around the circumference of the rotation axis of the second connection portion 701.

[0087] The first connection part 601 has a first arcuate edge 6011, and the second connection part 701 has a second arcuate edge 7011. In this way, when the back-rib mechanism 200 is installed at a negative corner and the rotation angle changes, the rotatable connection between the first connection part 601 and the second connection part 701 can be effectively prevented from interfering with the wall or the formwork casting surface; when the back-rib mechanism 200 is installed at a positive corner, rotational interference between the first connection part 601 and the second matching part 702 can be effectively avoided.

[0088] See also Fig.13 and Fig.17In some embodiments, the back rib support member 8 includes an adjustment rod 81 and at least one support rod 82. At least one end of the adjustment rod 81 is provided with an inner hole (not shown in the figure) along its length direction. The inner wall of the inner hole is provided with an inner thread. The outer wall of one end of the support rod 82 is provided with an outer thread. The inner thread on the adjustment rod 81 cooperates with the outer thread on the support rod 82, so that the support rod 82 can be screwed into or out of the inner hole from the end of the adjustment rod 81 having the inner hole.

[0089] The support rod 82 is designed to be a structural form of an adjusting rod 81 and a support rod 82. The end where the adjusting rod 81 is connected to the support rod 82 is provided with an inner hole with an internal thread, and the outer wall of one end of the support rod 82 is provided with an external thread. The support rod 82 can be screwed into / out of the inner hole through the threaded connection, thereby realizing the adjustable distance between the third connecting part 801 and the fourth connecting part 802 on the back rib support member 8.

[0090] Fig.13 It represents a back-rib mechanism 200 suitable for an obtuse internal angle. There are two support rods 82 which are respectively threadedly connected to both ends of the adjustment rod 81. The thread directions of the external threads on the two support rods 82 are opposite. Fig.17 It indicates that the back-rib structure 200 is suitable for an acute-angled outer corner, and the number of the support rod 82 is one.

[0091] An embodiment of the present application provides a template system 400, including two template devices 300, one template device 300 is installed at the inner corner, and the other template device 300 is installed at the outer corner.

[0092] The two template devices 300 adjust the template mechanisms 100 and the back-ribbed mechanisms 200 according to the preset corner angles. One template device 300 is set at the inner corner, and the other template mechanism 100 is set at the outer corner. Then the corner wall is cast. The template mechanism 100 and the back-ribbed mechanism 200 can be adjusted according to the actual corner angle requirements to meet the requirements of different angles.

[0093] See also Figure 1 In some embodiments, the middle connecting member of the formwork device 300 is a tension bolt 3001.
