Description

Technical Field

[0001] The present application belongs to the technical field of assembly and decoration, and in particular to a partition board device. Background Art

[0002] Partition boards are common prefabricated strips of partition walls used in non-load-bearing parts of buildings. They are mainly used for household partitions, room partitions, corridor partitions, stair partitions, etc. Partition boards need to be spliced ​​with corresponding partition boards. The commonly used splicing method with low cost and suitable for mass production is to add a mother groove on one side of the partition board, so that the mother grooves of the two partition boards are opposite and grouting is performed between the mother grooves of the two partition boards to achieve the connection of the two partition boards, and the molding is also relatively stable.

[0003] At present, for partition boards connected by grouting, the volume of the grouting is prone to change after the grouting is filled and solidified, causing larger solidification cracks in the grouting material, affecting the connection force between the partition boards, and also affecting the quality and service life of the isolation wall formed by the partition boards. Utility Model Content

[0004] The present application aims to at least to some extent solve the technical problem that the quality and service life of the partition wall formed by the partition wall panels are affected. To this end, the present application provides a partition wall panel device.

[0005] A partition board device provided in an embodiment of the present application includes:

[0006] A plurality of partition boards are sequentially arranged at intervals, wherein two opposite sides of the partition boards are each provided with a female groove, and the projection of the opening side of the female groove on the groove bottom side of the female groove falls on the groove bottom of the female groove;

[0007] The grouting layer is filled between the side portions corresponding to two adjacent partition boards and is filled into the mother groove.

[0008] In some embodiments, the female grooves of two adjacent partition boards are opposite to each other and extend in the same direction.

[0009] In some embodiments, there is a millimeter-level gap between two adjacent partition boards.

[0010] In some embodiments, the mother groove is a dovetail groove, and the side wall of the dovetail groove is provided with a plurality of micro grooves.

[0011] In some embodiments, the mother groove is a through groove, and the side portion is also provided with an L-shaped through groove extending along the extension direction of the mother groove, the two L-shaped through grooves are respectively located on both sides of the mother groove and the openings are away from the mother groove, and the partition board device also includes a mesh plaster layer filled between two L-shaped through grooves opposite to the openings of the two partition boards, and the mesh plaster layer is connected to the grouting layer.

[0012] In some embodiments, the depth of the female groove is less than the depth of the L-shaped through groove.

[0013] In some embodiments, the distance between the mother groove and the two L-shaped through grooves provided in the same partition board is the same.

[0014] In some embodiments, the mesh plaster layer includes a mortar body filled between the two L-shaped through grooves, and a steel mesh embedded in the mortar body.

[0015] In some embodiments, at least one steel bar is embedded in the partition board.

[0016] In some embodiments, at least two of the steel bars are embedded side by side in the partition board.

[0017] Advantageous effects provided by one or more embodiments of the present application:

[0018] In the partition board device, each partition board has two opposite sides provided with a mother groove, and the projection of the opening side of the mother groove on the bottom side of the mother groove falls on the bottom of the mother groove, so the opening of the mother groove tends to converge with respect to the bottom of the mother groove. When the grouting layer is filled between the corresponding sides of two adjacent partition boards, the grouting layer can realize the connection between the two adjacent partition boards, and the grouting layer is filled into the mother groove. The opening of the mother groove has a gripping effect on the grouting layer, so that the grouting layer close to the bottom of the mother groove can act on the inner wall of the mother groove, increasing the gripping force between the grouting layer and the mother groove. Even if the grouting layer has a volume change during the solidification process, the grouting layer can also effectively grip the mother groove, so as to improve the connection force between the two partition boards and improve the quality and service life of the partition wall formed by the partition boards. To a certain extent, it solves the technical problem that the quality and service life of the partition wall formed by the partition boards are affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Figure 1 A schematic structural diagram of a partition board device in some embodiments or certain embodiments of the present application is shown. Figure 2 FIG. 1 shows a schematic diagram of the matching state of a partition board in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 1 and Figure 2 , the embodiment of the present application provides a partition board device, including:

[0032] The partition wall panels 1 are arranged in plurality in sequence and at intervals. Two opposite side portions 11 of the partition wall panels 1 are both provided with female grooves 12 . The projection of the opening side of the female groove 12 on the groove bottom side of the female groove 12 falls on the groove bottom of the female groove 12 .

[0033] The grouting layer 2 is filled between the corresponding side portions 11 of two adjacent partition boards 1 and filled into the mother groove 12 .

[0034] In the partition board device, each partition board 1 has two opposite side portions 11 provided with a mother groove 12, and the projection of the opening side of the mother groove 12 on the bottom side of the mother groove 12 falls on the bottom of the mother groove 12, so the opening of the mother groove 12 tends to converge with respect to the bottom of the mother groove 12. When the grouting layer 2 is filled between the corresponding side portions 11 of two adjacent partition boards 1, the grouting layer 2 can realize the connection between the two adjacent partition boards 1, and the grouting layer 2 is filled into the mother groove 12, and the opening of the mother groove 12 has a gripping effect on the grouting layer 2, so that the grouting layer 2 near the bottom of the mother groove 12 can act on the inner wall of the mother groove 12, increasing the gripping force between the grouting layer 2 and the mother groove 12, even if the grouting layer 2 has a volume change during the solidification process, the grouting layer 2 can also effectively grip the mother groove 12, so as to improve the connection force between the two partition boards 1, and improve the quality and service life of the partition wall formed by the partition boards 1. To a certain extent, the technical problem that the quality and service life of the partition wall formed by the partition board 1 are affected is solved.

[0035] It should be noted that the grouting layer 2 can be formed by sealing the gap between the side portions 11 of the two partition boards 1 through a plate, a clamp or a tool, and then grouting is injected into the gap between the side portions 11 of the two partition boards 1, and the injected material is solidified and formed to form the grouting layer 2. After the grouting layer 2 is formed, the plate or tool is separated. The partition board device can be used as a whole in the partition wall structure that needs to be prepared by the partition board 1, or the partition board device can also constitute a partition wall itself according to actual needs.

[0036] In some embodiments, the female grooves 12 of two adjacent partition wall panels 1 are opposite to each other and extend in the same direction. The female grooves 12 of two adjacent partition wall panels 1 are opposite to each other and extend in the same direction, so the corresponding grouting layer 2 parts in the two opposite female grooves 12 and the gripping force between the female grooves 12 can be superimposed, effectively increasing the connection force between the two partition wall panels 1, so as to improve the quality and service life of the final partition wall.

[0037] In some embodiments, the female grooves 12 of two adjacent partition boards 1 may also extend in opposite directions with an angle therebetween, which is not limited in the present application.

[0038] In some embodiments, there may be a millimeter-level gap between two adjacent partition boards 1. Filling the grouting layer 2 into the millimeter-level gap is beneficial to improving the connection force between the grouting layer 2 and the partition board 1, and improving the quality and service life of the final partition wall.

[0039] It should be noted that the millimeter-level gap is a gap of 1 to 10 mm.

[0040] In some embodiments, the gap between two adjacent partition boards 1 may be less than or equal to 5 mm. The connection stability is good.

[0041] In some embodiments, the mother groove 12 is a dovetail groove, and the side wall 122 of the dovetail groove is provided with a plurality of micro grooves (not shown in the figure).

[0042] The dovetail-shaped mother groove 12 has a better gripping effect on the grouting layer 2, and the side wall 122 of the dovetail groove is provided with a plurality of micro grooves, which can further increase the adhesion between the grouting layer 2 and the mother groove 12, reduce the cracks formed when the grouting material solidifies into the grouting layer 2, and improve the connection between the partition boards 1, so as to improve the quality and service life of the partition wall formed by the partition boards 1. To a certain extent, the technical problem that the quality and service life of the partition wall formed by the partition boards 1 are affected is solved.

[0043] In some embodiments, the micro grooves on the side wall 122 can be obtained by roughening or carving smaller grooves inside the mother groove 12 of the partition wall board 1 using a special tool before the partition wall board 1 reaches the designed strength. This is to increase the effective bonding area between the expansion agent and the partition wall board 1 and enhance the joint strength of the partition wall board 1 after grouting. The preparation is simple and is also beneficial to the strength of the final partition wall board 1, so as to improve the quality and service life of the partition wall board device.

[0044] In some embodiments, in the mother groove 12 which is a dovetail groove, the angle α between the side wall 122 and the bottom surface 121 of the dovetail groove may be 60° to 80°.

[0045] When the angle is within the above range, the adhesion between the grouting layer 2 and the partition board 1 is better, and the connection between the two partition boards 1 is more stable, which is beneficial to extending the service life of the partition board device.

[0046] In some embodiments, the angle α may also be 55° to 60°, or 80° to 85°, which can greatly improve the adhesion between the grouting layer 2 and the partition board 1.

[0047] Figure 3 A partial structural diagram of a partition board in some embodiments or certain embodiments of the present application is shown, referring to Figure 3 It can be seen that in some embodiments, the mother groove 12 is a through groove, and the side portion 11 is also provided with an L-shaped through groove 13 extending along the extension direction of the mother groove 12, and the two L-shaped through grooves 13 are respectively located on both sides of the mother groove 12 and the openings are away from the mother groove 12. The partition board device also includes a mesh plaster layer 3 that fills the two L-shaped through grooves 13 with openings opposite to each other of the two partition boards 1, and the mesh plaster layer 3 is connected to the grouting layer 2.

[0048] The mother groove 12 is a through groove, and the grouting layer 2 can effectively connect two adjacent partition boards 1. The side 11 of the partition board 1 is also provided with an L-shaped through groove 13 along the extension direction of the mother groove 12. The two L-shaped through grooves 13 are respectively located on both sides of the mother groove 12 and the openings are away from the mother groove 12, which can be used to position and close the grouting layer 2 in the mother groove 12. The partition board device also includes a mesh plastering layer 3 filled between the two L-shaped through grooves 13 with openings facing each other in the two partition boards 1, and the mesh plastering layer 3 is connected to the grouting layer 2. On the one hand, the L-shaped through groove 13 can be used with a sealing plate or a tool to close the gap between the side 11 of the two partition boards 1, and then fill the grouting layer 2. On the other hand, after the grouting layer 2 is solidified, the L-shaped through groove 13 with openings facing each other between the two partition boards 1 can be meshed and plastered to enhance the connection force between the two partition boards 1, so as to improve the quality and service life of the final partition wall. The L-shaped through groove 13 is stepped and almost at a right angle, and can also confine the volume of the mesh plaster layer 3 between the matching part and the board body, reducing secondary cracks caused by expansion stress of the mortar, and improving the overall quality and service life of the partition board device.

[0049] In some embodiments, the depth of the female groove 12 is less than the depth of the L-shaped through groove 13. This is beneficial to ensure the overall strength and quality of the partition wall board 1, and the connection strength between the two partition wall boards 1 is also good.

[0050] In some embodiments, the distance between the mother groove 12 and the two L-shaped through grooves 13 provided in the same partition wall board 1 is the same. The force between the mesh plaster layer 3 and the grouting layer 2 is relatively uniform, which is also conducive to improving the connection stability between the two partition wall boards 1, so as to improve the quality and service life of the final partition wall.

[0051] In some embodiments, the partition board 1 may be in the shape of a cuboid, and the portions corresponding to the two opposite side surfaces 14 with smaller areas may be configured as the two side portions 11 of the partition board 1, and the two opposite surfaces with the largest areas may be the two board surfaces 15 of the partition board 1, respectively, and the board surfaces 15 and the side surfaces 14 are perpendicular to each other. Both the female groove 12 and the L-shaped through groove 13 may extend in a square shape along the length of the partition board 1 and penetrate the partition board 1. When the female groove 12 is a dovetail groove, the bottom surface 121 of the female groove 12 may be arranged along the normal direction of the board surface 15, and the two L-shaped through grooves 13 and the female groove 12 of the same side portion 11 of the partition board 1 may be spaced apart in sequence along the normal direction of the board surface 15, and the female groove 12 is located between the two L-shaped through grooves 13. The two side surfaces of the L-shaped through groove 13 may be perpendicular to each other and parallel to the board surface 15 and the side surface 14 of the partition board 1, respectively.

[0052] In some embodiments, when the partition board 1 is in the shape of a rectangular parallelepiped, along the normal direction A2 of the side surface 14, the ratio of the depth D1 of the mother groove 12 to the depth H1 of the L-shaped through groove 13 can be 0.5 to 0.7. While being able to effectively increase the connection stability between the two partition boards 1, it is beneficial to the strength of the partition board 1 itself, so as to improve the quality and service life of the partition wall finally formed by the partition board device. On the normal direction A1 of the board surface 15, the ratio of the opening width B4 of the mother groove 12 to the spacing B1 between the two L-shaped through grooves 13 is less than or equal to (1 / 3), the ratio of the opening width B4 of the mother groove 12 to the width of the bottom surface 121 is less than or equal to 0.7, and the ratio of the width of the bottom surface 121 to the spacing B1 between the two L-shaped through grooves 13 is not greater than 0.5. While being able to effectively increase the connection stability between the two partition boards 11, it is beneficial to the strength of the partition board 11 itself, so as to improve the quality and service life of the partition wall finally formed by the partition board device.

[0053] For ease of understanding, Figure 3 1 shows the normal direction A2 of the side surface of the partition board 1 and the normal direction A1 of the board surface 15. The structure is simple, suitable for mass production, and the overall service life is long.

[0054] Figure 4 A schematic diagram of the cross-sectional structure of a partition board in some embodiments or certain embodiments of the present application is shown, with reference to Figure 4 In some embodiments, the ratio of the cross-sectional area S1 of the mother groove 12 to the cross-sectional area S2 of the portion between the two corresponding L-shaped through grooves 13 of the partition board 1 is greater than or equal to 0.25 and less than or equal to 0.33.

[0055] It can effectively increase the connection stability between the two partition boards 1 and is beneficial to the strength of the partition board 1 itself, so as to improve the quality and service life of the partition wall finally formed by the partition board device.

[0056] In some embodiments, the height dimension of the partition board 1 in the normal direction A1 of the board surface 15 can be 100 mm and 200 mm, or can be 250 mm or 300 mm. The corresponding matching portion and the female groove 12 on the partition board 11 can be prepared according to the height dimension of the partition board 1.

[0057] In some embodiments, the mesh plaster layer 3 may include a mortar body filled between two L-shaped grooves 13, and a steel mesh embedded in the mortar body (the steel mesh is embedded in the final mortar body and is therefore not shown in the figure).

[0058] The steel wire mesh has good toughness, and can improve the quality of the mesh plastering, so as to improve the quality of the mesh plastering layer 3, so that the joint safety, integrity and stability of the partition board 1 are better.

[0059] It should be noted that the mesh plaster layer 3 can be formed by first laying a steel mesh and connecting it to two opposite partition boards 1, and then plastering it into the L-shaped through groove 13, so as to gradually form the mesh plaster layer 3 connecting the side portions 11 of the two adjacent partition boards 1.

[0060] Figure 5 FIG. 1 shows a schematic diagram of the structure of a partition board in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 5 It can be seen that in some embodiments, at least one steel bar 16 is embedded in the partition board 1. The strength of the partition board 1 itself can be improved to improve the overall quality and service life of the partition board device, and to improve the service life and quality of the partition wall to which the partition board device is finally applied.

[0061] In some embodiments, at least two steel bars 16 are embedded side by side in the partition board 1. This is more effective in improving the quality of the partition board 1. The steel bars 16 are completely located in the partition board 1 and therefore will not affect the preparation of the grouting layer 2.

[0062] It should be noted that the parallel or perpendicular mentioned in the present application is relative to the concept of absolute parallel or absolute perpendicular in geometry, and a deviation of 0 to 5° is allowed, and the present application does not impose any limitation on this.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
