Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a back-studding mechanism and a back-studding device. BACKGROUND

[0002] Back-studding is mainly used in formwork support systems in building construction, and its specific function is to provide additional support for building formwork to ensure that the building formwork does not deform or shift when bearing the weight of concrete and construction loads.

[0003] Further, for external corners and internal corners, special back-studding pieces such as L-shaped or T-shaped back-studding are usually provided to better fit the shape of the corners and provide effective support. However, in current building construction, corners are no longer limited to standard 90 degrees, and for non-standard different corner angles, such as acute angles or obtuse angles, custom-made back-studding is required. Moreover, the structures of back-studding pieces installed at internal corners and external corners are usually not the same, and different corner angles will increase the cost of customization. CONTENT OF THE INVENTION

[0004] Therefore, the present application provides a back-studding mechanism and a back-studding device that can adapt to different angle corners and can be installed at both internal corners and external corners of the corners.

[0005] An embodiment of the present application provides a back-studding mechanism, comprising a first back-studding and a second back-studding. The first back-studding is detachably connected to the second back-studding, and the first back-studding is configured to be rotatable relative to the second back-studding. The first back-studding has a first connecting portion and a first matching portion. The second back-studding has a second connecting portion and a second matching portion. The back-studding mechanism further comprises a support piece. The support piece has a third connecting portion and a fourth connecting portion. The third connecting portion is detachably connected to the first back-studding, and the fourth connecting portion is detachably connected to the second back-studding. When the back-studding mechanism is installed at an internal corner, the first connecting portion and the second connecting portion are connected, the third connecting portion and the first matching portion are connected, and the fourth connecting portion and the second matching portion are connected. When the back-studding mechanism is installed at an external corner, the first connecting portion and the second matching portion are connected, the third connecting portion and the first matching portion are connected, and the fourth connecting portion and the second connecting portion are connected. The support piece is configured to adjust the distance between the third connecting portion and the fourth connecting portion, so as to adjust the included angle between the first back-studding and the second back-studding.

[0006] In the above embodiment, the support is arranged between the first back formwork and the second back formwork, and the two ends of the support provide support force to the first back formwork and the second back formwork. The support is further configured to have an adjustable distance between the third connecting part and the fourth connecting part, so that the included angle between the first back formwork and the second back formwork is adjustable. Thus, the back formwork mechanism can be adjusted according to the corner angle, and the requirements of multiple different angles can be met. The first connecting part and the first matching part are arranged on the first back formwork, and the second connecting part and the second matching part are arranged on the second back formwork. The connection between the first back formwork and the second back formwork is designed to be detachable. When the back formwork mechanism is installed in the inside corner, the first connecting part of the first back formwork and the second connecting part of the second back formwork are connected, the third connecting part of the support and the first matching part of the first back formwork are connected, and the fourth connecting part of the support and the second matching part of the second back formwork are connected. When the back formwork mechanism is installed in the outside corner, the first connecting part of the first back formwork and the second matching part of the second back formwork are connected, the third connecting part of the support and the first matching part of the first back formwork are connected, and the fourth connecting part of the support and the second connecting part of the second back formwork are connected. In this way, by changing the connection position between the first back formwork, the second back formwork and the support, one back formwork mechanism can be used for inside corners and outside corners with different corner angles.

[0007] In some embodiments of the present application, the back formwork mechanism further comprises a connecting assembly. The connecting assembly comprises two connecting members. Each connecting member comprises a rotating part and a mounting part. One connecting member is a first connecting member, and the other connecting member is a second connecting member. The mounting part of the first connecting member is detachably connected with the first matching part. The mounting part of the second connecting member is detachably connected with the second matching part. When the back formwork mechanism is installed in the inside corner, the third connecting part is rotatably connected with the rotating part of the first connecting member, and the fourth connecting part is rotatably connected with the rotating part of the second connecting member. When the back formwork mechanism is installed in the outside corner, the first connecting part is rotatably connected with the rotating part of the second connecting member, and the third connecting part is rotatably connected with the rotating part of the first connecting member.

[0008] In the above embodiment, the connecting assembly including two connecting members is designed, which are respectively used for supporting and disassembling between the supporting member and the first and second back braces. The uniform connecting members are convenient for storage. Each connecting member includes a rotating part and a mounting part. The mounting part is used for connecting the connecting member and the first and second back braces. The rotating part is connected with the third and fourth connecting parts of the supporting member. In this way, when the angle of the corner changes, the distance between the third and fourth connecting parts is adjusted. If the back brace mechanism is installed in the inside corner, the third and fourth connecting parts can be respectively connected with the rotating parts of the first and second connecting members to realize the rotation of the supporting member relative to the first and second back braces to adapt to the change of the angle of the corner. When the back brace mechanism is installed in the outside corner, the rotating part of the first connecting member can make the supporting member rotate relative to the first back brace, and the rotating part of the second connecting member can make the first back brace rotate relative to the second back brace.

[0009] In some embodiments of the present application, the plurality of first matching parts are spaced apart in a direction away from the first connecting part. The mounting part of the first connecting member is connected with any first matching part. The plurality of second matching parts are spaced apart in a direction away from the second connecting part. The mounting part of the second connecting member is connected with any second matching part.

[0010] In the above embodiment, the first and second matching parts are provided in plurality, which can adjust the position of the connecting member according to the actual installation size requirement to ensure that the supporting member can provide effective supporting force to the first and second back braces.

[0011] In some embodiments of the present application, the connecting assembly further includes a fixing member. The mounting part of the first connecting member is fixed with the first matching part through the fixing member. The mounting part of the second connecting member is fixed with the second matching part through the fixing member.

[0012] In the above embodiment, the fixing member is further designed. Because the installation position of the connecting member on the first and second back braces will be adjusted according to the actual situation, when the installation position of the first and second connecting members is determined, the first and second connecting members are fixed through the fixing member to avoid the relative movement between the first and second connecting members and the first and second back braces, so that the whole back brace mechanism is stable and reliable.

[0013] In some embodiments of the present application, the first fitting part has a first support surface and a second support surface. The first support surface and the second support surface are arranged opposite to each other. The second fitting part has a third support surface and a fourth support surface. The third support surface and the fourth support surface are arranged opposite to each other. When the back battening mechanism is installed at an inside corner, the second support surface and the fourth support surface are used to abut against the side of the wall surface or the formwork pouring surface opposite to the side on which the support is provided, the mounting part of the first connecting piece is connected to the first support surface, and the mounting part of the second connecting piece is connected to the third support surface. When the back battening mechanism is installed at an outside corner, the first support surface and the third support surface are used to abut against the side of the wall surface or the formwork pouring surface opposite to the side on which the support is provided, the mounting part of the first connecting piece is connected to the second support surface, and the mounting part of the second connecting piece is connected to the third support surface.

[0014] In the above embodiments, each support surface on the first fitting part and the second fitting part is used to abut against or abut away from the side of the wall surface or the formwork pouring surface opposite to the side on which the support is provided according to the actual installation condition (inside corner or outside corner). When the back battening mechanism is installed at an inside corner, the first support surface and the third support surface are subjected to the support force provided by the support piece, and when the back battening mechanism is installed at an outside corner, the second support surface and the third support surface are subjected to the support force, so as to ensure that the support force provided by the support piece can be effectively transmitted to the first back battens and the second back battens.

[0015] In some embodiments of the present application, a first connecting groove is formed on the first support surface at a position corresponding to the first fitting part. A second connecting groove is formed on the second support surface at a position corresponding to the first fitting part. A third connecting groove is formed on the third support surface at a position corresponding to the second fitting part. When the back battening mechanism is installed at an inside corner, the mounting part of the first connecting piece is located in the first connecting groove, and the mounting part of the second connecting piece is located in the third connecting groove. When the back battening mechanism is installed at an outside corner, the mounting part of the first connecting piece is located in the second connecting groove, and the mounting part of the second connecting piece is located in the third connecting groove.

[0016] In the above embodiments, the connecting grooves are formed on the first support surface, the second support surface and the third support surface at positions corresponding to the fitting parts, so that the mounting parts of the connecting pieces can be correspondingly located in the connecting grooves, and the connection strength between the connecting pieces and the first back battens and the second back battens is more stable and reliable.

[0017] In some embodiments of the present application, each connecting piece further comprises a stopper. The stopper is located between the rotating part and the mounting part. When the back-studding device is installed in an internal corner, the stopper of the first connecting piece abuts against the first supporting surface to reach a preset depth when the mounting part of the first connecting piece is inserted into the first connecting groove, and the stopper of the second connecting piece abuts against the second supporting surface to reach a preset depth when the mounting part of the second connecting piece is inserted into the third connecting groove. When the back-studding device is installed in an external corner, the stopper of the first connecting piece abuts against the third supporting surface to reach a preset depth when the mounting part of the first connecting piece is inserted into the second connecting groove, and the stopper of the second connecting piece abuts against the second supporting surface to reach a preset depth when the mounting part of the second connecting piece is inserted into the third connecting groove.

[0018] In the above embodiments, the stopper is further provided between the mounting part and the rotating part of the connecting piece, so that the mounting part of each connecting piece can be accurately inserted into the corresponding connecting groove by abutting the stopper against the corresponding supporting surface.

[0019] In some embodiments of the present application, the first connecting part has a first arc-shaped edge. The first arc-shaped edge extends around the circumference of the rotation axis of the first connecting part. The second connecting part has a second arc-shaped edge. The second arc-shaped edge extends around the circumference of the rotation axis of the second connecting part.

[0020] In the above embodiments, the first connecting part has a first arc-shaped edge, and the second connecting part has a second arc-shaped edge, so that when the back-studding device is installed in an internal corner and the angle of the corner changes, the rotating connection between the first connecting part and the second connecting part on the side away from the wall surface or the formwork surface can be effectively avoided. When the back-studding device is installed in an external corner, the rotating connection between the first connecting part and the second connecting part can be effectively avoided.

[0021] In some embodiments of the present application, the supporting piece comprises an adjusting rod and at least one supporting rod. The adjusting rod has an inner hole at one end along the length direction of the adjusting rod. The inner wall of the inner hole is provided with an inner thread. The outer wall of one end of the supporting rod is provided with an outer thread. The inner thread of the adjusting rod and the outer thread of the supporting rod are matched to enable the supporting rod to be screwed into or out of the inner hole from the end of the adjusting rod having the inner hole.

[0022] In the above embodiments, the supporting rod is designed as an adjusting rod and a supporting rod. The end of the adjusting rod connected to the supporting rod is provided with an inner hole having an inner thread, and the outer wall of one end of the supporting rod is provided with an outer thread. The supporting rod can be screwed into or out of the inner hole through the thread matching connection, so that the distance between the third connecting part and the fourth connecting part of the supporting piece can be adjusted.
