Description

Technical Field

[0001] The present invention belongs to the technical field of assembled composite boards, and particularly relates to an installation structure for interior and exterior corners of prefabricated walls. Background Art

[0002] In decoration projects, the diversity and durability of the tile finish are deeply loved by consumers. However, the current construction method for tiling is still wet work, that is, tiling is carried out through cement mortar or adhesive mortar. The current construction method highly tests the skills of workers. There are many uncontrollable factors during the construction process, and it also consumes more materials and labor costs. The dust generated on-site is large, the construction period is long, and common quality problems such as tile hollowing, arching, and falling off are prone to occur. Moreover, in secondary decoration projects, the repair and replacement of the tile finish require violent demolition and chiseling of the wall, damaging the main structure and generating a lot of construction waste, which greatly wastes resources.

[0003] The installation form of the integral bathroom is to pre-compound the tiles and the base board in the factory, and then install them through simple assembly by on-site workers. This process not only reduces the technical threshold of workers, but also eliminates the need for on-site tile cement pasting, fundamentally solving common problems such as large on-site dust, long construction period, and high labor costs.

[0004] The document with the application publication number CN108086627A discloses a rapid installation structure for composite wallboards and its installation method, including an overall frame system for composite wallboards. The overall frame system for composite wallboards includes an installation system for interior corners of composite wallboards, an installation system for exterior corners of composite wallboards, and a plane splicing system for composite wallboards. The installation system for interior corners of composite wallboards includes a tile composite board and an interior corner profile for installing the tile composite board. One end of the interior corner profile is fixedly connected to the tile composite board, and the other end is provided with a flat joint piece in cooperation, and is fixedly connected to the tile composite board through the flat joint piece; the installation system for exterior corners of composite wallboards includes a tile composite board and an exterior corner fixing piece and an exterior corner clamping piece for installing the tile composite board.

[0005] However, this structure still has the following problems: The interior corner uses a segmented installation method, making it difficult for workers to control the installation accuracy during assembly, resulting in poor installation quality; the exterior corner uses a closing strip form, with poor decorative effects.

Detailed implementation Embodiment

[0028] An assembled wall inside and outside corner installation structure, as shown in the attached Figure 1 , 2 figure, includes an inside corner side plate 11, a middle plate 12, and an outside corner side plate 13 connected in sequence, an inside corner connection system arranged at the connection of the inside corner side plate 11 and the middle plate 12, and an outside corner connection system arranged at the connection of the outside corner side plate 13 and the middle plate 12; wherein, the inside corner connection system includes an inside corner reinforcing profile 1 with one end connected to the inside corner side plate 11 and the other end connected to the middle plate 12, and two inside corner connecting profiles 2 respectively arranged on the inside corner side plate 11 and the middle plate 12 and connected to the inside corner reinforcing profile 1.

[0029] In this embodiment, as shown in the attached Figure 3 figure, the inside corner connecting profile 2 includes a first right-angled side 201, a second right-angled side 202 arranged at the end of the first right-angled side 201 and connected to the first right-angled side 201, a first plugging protrusion 203 arranged on the first right-angled side 201 and used for connecting with the side end of the inside corner side plate 11 or the middle plate 12, and a reinforcing connecting plate member 204 arranged on the second right-angled side 202 and used for connecting with the bottom end of the inside corner side plate 11 or the middle plate 12.

[0030] In this embodiment, on the basis that the first right-angled side 201 is connected to the second right-angled side 202 to form a right-angled component, a first plugging protrusion 203 is added for the plugging connection relationship with the inside corner side plate 11 and the middle plate 12, thereby strengthening the fixing effect of the component on the composite plate in the end direction of the composite plate, that is, the inside corner side plate 11 and the middle plate 12; in this embodiment, further on the basis that the first right-angled side 201 is connected to the second right-angled side 202 to form a right-angled component, a reinforcing connecting plate member 204 is added, and its main function is to provide a force to support the composite plate in the direction perpendicular to the composite plate, that is, the inside corner side plate 11 and the middle plate 12, and can also play a role in improving the leveling efficiency during assembly.

[0031] In this embodiment, as shown in the appendix Figure 4 As shown, the reinforcing connecting plate member 204 includes a first vertical side 204a provided at the side end of the second right-angled side 202, a supporting inclined side 204b provided at the side end of the first vertical side 204a, a second vertical side 204c provided at the side end of the supporting inclined side 204b, and a connecting plate 204d provided at the side end of the second vertical side 204c and connected to the bottom end of the internal corner side plate 11 or the intermediate plate 12.

The main function of setting the supporting inclined side 204b in this embodiment is to consider the risk that the composite plates on the outer surface, namely the internal corner side plate 11 and the intermediate plate 12, are prone to deformation when subjected to external forces during assembly. Setting the supporting inclined side 204b with a certain angle to the wall surface can well buffer the acting force on the composite plate and reduce the risk of deformation of the composite plate. In this embodiment, the angle between the supporting inclined side 204b and the wall is preferably within the range of 5-10°.

[0034] In this embodiment, the L-shaped plate 204e, the third vertical side 204f, and the reinforcing plate 204g are also integrally formed steel structures. Among them, the L-shaped plate 204e is used to be clamped with the connecting plate 204d, and its function is to limit the position of the connecting plate 204d and prevent the connecting plate 204d from slipping; the main functions of the third vertical side 204f and the reinforcing plate 204g are to jack up the supporting inclined side 204b and reduce the risk of deformation of the supporting inclined side 204b.

Its functions mainly include: First, the two ends of the internal corner strengthening profile 1 are respectively connected to two internal corner connecting profiles 2 respectively connected to the internal corner side plate 11 and the middle plate 12, thus forming an integral component of internal corner connecting profile - internal corner strengthening profile - internal corner connecting profile. During installation, there is no need to install in blocks. It can be first assembled into a whole and then installed at the connection of the internal corner side plate 11 and the middle plate 12, greatly improving the assembly accuracy, reducing the installation difficulty, and improving the aesthetic effect of the connection; Second, the internal corner strengthening profile 1 strengthens the structural strength of the connection between the internal corner side plate 11 and the middle plate 12, reducing the serious consequences of dislocation and fracture of the connection under external force; Third, the internal corner strengthening profile 1 not only strengthens the connection strength between the internal corner connecting profile 2 and the side ends of the internal corner side plate 11 and the middle plate 12, but also strengthens the connection strength between the internal corner connecting profile 2 and the bottom ends of the internal corner side plate 11 and the middle plate 12, integrally improving the mechanical strength of the internal corner connection system.

[0037] In this embodiment, as shown in the appendix Figure 6 As shown, the external corner connection system includes an external corner fixing profile 301 provided at the connection of the external corner side plate 13 and the middle plate 12, two external corner connecting profiles 302 respectively provided at the bottom ends of the external corner side plate 13 and the middle plate 12 close to the connection and connected to the two ends of the external corner fixing profile 301, and two second fixing screws 303 respectively provided on the two external corner connecting profiles 302 and connected to the external corner side plate 13 and the middle plate 12.
