Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connection structures, and particularly relates to a mother-son groove off-seam and close-fitting structure. Background Art
[0002] In prefabricated buildings, the mother-son groove close-fitting and off-seam structure can be used to connect prefabricated components such as wall panels, floor slabs, beam columns, etc. This structural form can improve the construction efficiency of buildings, reduce on-site work volume, and at the same time ensure the quality and stability of buildings.
[0003] In the prior art, a mother-son groove off-seam structure requires a plate structure and a profile to achieve a wide joint between two connecting plates, while a mother-son groove close-fitting structure requires another plate structure and a profile to achieve a close-fitting seam between two connecting plates. This results in the need to prepare a large number of goods for the off-seam and close-fitting structures respectively, causing a relatively high cost for the factory.
[0004] Therefore, there is a need to provide a close-fitting and off-seam structure that can form a close-fitting seam or a wide joint through the same-shaped plate. Summary of the Utility Model
[0005] An embodiment of the utility model provides a mother-son groove off-seam and close-fitting structure to solve the problems in the prior art.
[0006] The embodiment of the utility model adopts the following technical solution: A mother-son groove off-seam and close-fitting structure includes a first plate, a second plate, a close-fitting profile, and an off-seam profile; the mother groove slot on the first plate and the son groove slot on the second plate cooperate to achieve the assembly of the first plate and the second plate; at least part of the close-fitting profile is installed between the mother groove slot and the son groove slot so that a close-fitting seam is formed between the first plate and the second plate, and at least part of the off-seam profile is installed between the mother groove slot and the son groove slot so that a wide joint is formed between the first plate and the second plate, and the thickness of the wide joint is greater than the thickness of the close-fitting seam. When using the same plate structure, only different types of close-fitting profiles or off-seam profiles need to be distinguished for use to be applicable to both close-fitting and off-seam structures.
[0007] Preferably, the first plate and the second plate have the same thickness and are installed on the same plane, and this method can be used for the installation of wall panels.
[0008] Preferably, at least part of the opening of the mother groove slot is located on the back of the first plate, and the thickness of the mother groove slot is less than the thickness of the first plate; at least part of the opening of the son groove slot is located on the front of the second plate, and the thickness of the son groove slot is less than the thickness of the second plate. When the first plate and the second plate are assembled together through the close-fitting profile or the off-seam profile, the operator can push or pull the first plate and the second plate to make the mother groove slot and the son groove slot slide relative to each other, so as to realize the rapid connection and separation of the plates.
[0009] Preferably, the close-fitting profile includes a first partition; when the first and second panels are connected using the close-fitting profile, the first partition is located in the mother slot and is pressed against the wall of the mother slot by the end of the second panel extending into the mother slot. The close-fitting seam is the gap formed between the end of the first panel extending into the sub-slot and the wall of the sub-slot. By adding the first partition between the first and second panels, a close-fitting seam can be formed between the two panels. This close-fitting seam connection allows the panels to support each other, enhancing the stability of the overall structure.
[0010] Preferably, the close seam is located on the front sides of the first panel and the second panel.
[0011] Preferably, the close-fitting profile further comprises a base plate fixedly connected to the first partition and the two are at right angles. After the first partition is installed in place, the base plate is tightly attached to the back surfaces of the first plate and the second plate to ensure the stability of the connection.
[0012] Preferably, a first slot is formed on the inner wall surface of the female slot, extending longitudinally through the first plate. The first slot is located in the middle of the thickness direction of the first plate. A stopper plate is formed at the end of the first partition away from the base plate, parallel to the base plate. The stopper plate extends into the first slot and abuts against a side wall of the first slot near the back of the first plate. The first slot serves as a reserved gap to prevent installation and fixation difficulties caused by uneven slotting or uneven wall surfaces.
[0013] Preferably, the gap profile adds a second partition plate to the base plate, first partition plate, and limit plate of the close-fitting profile. The second partition plate is fixedly connected to the base plate and arranged parallel to the first partition plate. When the gap profile is used to connect the first and second panels, the first and second partition plates are both located in the mother groove, with the first partition plate resting on the wall surface of the mother groove, and the second partition plate resting on the end of the second panel extending into the mother groove. The wide seam is the gap formed between the end of the first panel extending into the sub-groove and the wall surface of the sub-groove. By placing the first and second partition plates between the first and second panels, a wide seam can be formed between the two panels. The wide seam can become a unique design element, adding personality and style to the panel decoration.
[0014] Preferably, the wide seam is located on the front sides of the first panel and the second panel.
[0015] At least one of the above technical solutions adopted in the embodiment of the present utility model can achieve the following beneficial effects:
[0016] The connection and cooperation of the first plate member and the second plate member with the closely-fitted profile can form a closely-fitted structure, and the connection and cooperation of the first plate member and the second plate member with the gap profile can form a gap structure. Therefore, when using the same plate member structure, only different models of closely-fitted profiles or gap profiles need to be distinguished for use, which can be applied to both closely-fitted and gap structures. Therefore, the inventory preparation in the factory warehouse can also be greatly reduced, and the most troublesome inventory problem in the factory can be cleverly streamlined through a general structure, mainly by streamlining the quantity of plate members that occupy a large cost, effectively reducing costs and increasing efficiency. In addition, using profiles to fix the closely-fitted and gap structures can increase the structural stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0028] The following will, in conjunction with the drawings, detail the technical solutions provided by each embodiment of the present utility model.
[0029] Refer to Figures 1 to 7 As shown, an embodiment of the present utility model provides a mother-daughter groove off-seam close-fitting structure, including a first plate member 1, a second plate member 2, a close-fitting profile 3 and an off-seam profile 4. The first plate member 1 and the second plate member 2 are assembled and connected through a mother-daughter groove structure.
[0030] Specifically, as Figure 5 shown, the first plate member 1 is provided with a mother groove slot 11, and the mother groove slot 11 is a structure for cooperating with the daughter groove slot 21 on the second plate member 2. The shape, size and position of the mother groove slot 11 are designed to be closely matched with the daughter groove slot 21, so as to achieve the precise assembly of the first plate member 1 and the second plate member 2.
[0031] The second plate member 2 is provided with a daughter groove slot 21, and the daughter groove slot 21 cooperates with the mother groove slot 11 on the first plate member 1 for connecting the two plate members. The design of the daughter groove slot 21 ensures effective docking with the mother groove slot 11, ensuring the structural stability of the assembled first plate member 1 and second plate member 2.
[0032] Refer to Figure 3 、 Figure 5 and Figure 6 shown, at least part of the close-fitting profile 3 is installed between the mother groove slot 11 and the daughter groove slot 21, so that a close-fitting seam 5 can be formed between the first plate member 1 and the second plate member 2. The formation of the close-fitting seam 5 makes there be no gap or a very small gap between the two plate members (in actual application, when the close-fitting profile 3 is used for the installation of the wall panel, the maximum size of the close-fitting seam 5 is 0.5 mm), improving the sealing performance of the connection part and the compactness of the overall structure.
[0033] Refer to Figure 4 、 Figure 5 and Figure 6As shown, the separation profile 4 is at least partially installed between the main slot 11 and the sub-slot 21, forming a wide joint 6 between the first panel 1 and the second panel 2. (In actual application, when the close-fitting profile 3 is used for installing wall panels, the close-fitting joint 5 is 2-3 mm.) The thickness of the wide joint 6 is greater than that of the close-fitting joint 5. This allows for a certain amount of adjustment while meeting certain connection requirements between the two panels, ensuring that the connection has a certain degree of cushioning and deformation capacity when subjected to external forces.
[0034] The connection of the first panel 1 and the second panel 2 with the close-fitting profile 3 forms a close-fitting structure, while the connection of the first panel 1 and the second panel 2 with the gap-separating profile 4 forms a gap-separating structure. Therefore, when using the same panel structure, it is only necessary to distinguish and use different types of close-fitting profiles 3 or gap-separating profiles 4 to adapt to both close-fitting and gap-separating structures. Therefore, it can also significantly reduce the inventory stock in the factory warehouse, cleverly reducing the factory's most troublesome inventory problem through a universal structure, mainly by reducing the number of panels that occupy higher costs, effectively reducing costs and increasing efficiency. In addition, the use of profiles to fix the close-fitting and gap-separating structures can increase structural stability.
[0035] In some practical applications, the first plate 1 and the second plate 2 have the same thickness and are installed on the same plane. This method can be used for wall panel installation, that is, the first plate 1 and the second plate 2 are both wall panels.
[0036] Specifically, such as Figures 3 to 5 As shown, the mother groove position 11 is at least partially opened on the back side of the first plate 1, and the thickness of the mother groove position 11 is less than the thickness of the first plate 1, and the sub-groove position 21 is at least partially opened on the front side of the second plate 2, and the thickness of the sub-groove position 21 is less than the thickness of the second plate 2. Therefore, when the first plate 1 and the second plate 2 are assembled together by the close-fitting profile 3 or the gap profile 4, the operator can push or pull the first plate 1 and the second plate 2 to make the mother groove position 11 and the sub-groove position 21 slide relative to each other, thereby realizing rapid connection and separation of the plates.
[0037] In some practical applications, such as Figure 3 and Figure 5 As shown, the close-fitting profile 3 includes a first partition 31; when the first plate 1 and the second plate 2 are connected by the close-fitting profile 3, the first partition 31 is located at the mother groove position 11 and is pressed against the wall of the mother groove position 11 by the end of the second plate 2 extending into the mother groove position 11, and the close-fitting seam 5 is the gap formed between the end of the first plate 1 extending into the sub-groove position 21 and the wall of the sub-groove position 21.
[0038] In this embodiment, by adding a first partition 31 between the first plate member 1 and the second plate member 2, a tight joint seam 5 can be formed between the two plates. The connection method of the tight joint seam 5 enables the plates to support each other, enhancing the stability of the overall structure. Especially when the plates are used in a large area, the tight joint seam 5 can effectively disperse stress and prevent the plates from deforming or cracking. Specifically, the tight joint seam 5 is located on the front surfaces of the first plate member 1 and the second plate member 2. The tight joint seam 5 makes the connection between the plates tight, and almost no obvious gap can be seen from the front, presenting a continuous and smooth surface. This greatly improves the overall aesthetics after the plates are installed.
[0039] Specifically, as Figure 3 and Figure 5 shown, the tight joint profile 3 further includes a base plate 32 fixedly connected to the first partition 31 and perpendicular to each other. After the first partition 31 is installed in place, the base plate 32 is closely attached to the back surfaces of the first plate member 1 and the second plate member 2.
[0040] In some practical applications, as Figure 3 and Figure 5 shown, a first slot 12 longitudinally penetrating the first plate member 1 is formed on the inner wall surface of the female groove slot 11. The first slot 12 is located at the middle position in the thickness direction of the first plate member 1. When the first plate and the second plate are used for installing the wall panel, the first slot 12 serves as a reserved gap to prevent difficulties in installation and fixation caused by uneven grooving or uneven wall surfaces. It can also prevent uneven installation gaps caused by slight deformation of the plates.
[0041] As Figure 3 and Figure 5 shown, a limiting plate 33 parallel to the base plate 32 is further formed at one end of the first partition 31 away from the base plate 32. The limiting plate 33 extends into the first slot 12 and abuts against one side wall of the first slot 12 close to the back surface of the first plate member 1. The limiting plate 33 is used for limiting and can ensure that the base plate 32 is closely attached to the first plate and the second plate.
[0042] In some practical applications, as Figures 3 to 5As shown, the gap profile 4 is an improvement on the above-mentioned close-fitting profile 3, mainly by adding a second partition 41 on the basis of the base plate 32, first partition 31 and limit plate 33 of the close-fitting profile 3. The second partition 41 is fixedly connected to the base plate 32 and arranged parallel to the first partition 31. When the first plate 1 and the second plate 2 are connected by the gap profile 4, the first partition 31 and the second partition 41 are both located in the mother groove position 11, the first partition 31 abuts against the wall surface of the mother groove position 11, and the second partition 41 abuts against the end of the second plate 2 extending into the mother groove position 11. The wide seam 6 is the gap formed between the end of the first plate 1 extending into the sub-groove position 21 and the wall surface of the sub-groove position 21. Specifically, the wide seam 6 is located on the front surface of the first plate 1 and the second plate 2.
[0043] In this embodiment, by placing the first and second partitions 31 and 41 between the first and second panels 1 and 2, a wide seam 6 is formed between the two panels. This wide seam 6 can become a unique design element, adding personality and style to the panel decoration. The lines and shapes of the wide seam 6 can be creatively designed to create diverse visual effects. The wide seam 6 can also be filled with metal strips or other decorative materials to create a rugged, rugged atmosphere. Furthermore, the wide seam 6 provides room for deformation of the panels, reducing problems such as buckling and cracking caused by deformation.
[0044] The wide seam 6 provides a margin of error during panel installation, making installation easier and more accurate. If there are any errors in the panel dimensions, the wide seam 6 can accommodate these errors, avoiding installation difficulties caused by inaccurate dimensions.
[0045] A wall panel installation structure applies the above-mentioned parent-child groove close-jointed structure, wherein the first panel 1 and the second panel 2 are both wall panels, the backs of the first panel 1 and the second panel 2 are installed on the wall by structural adhesive, and the base plate 32 is fixed to the wall by air gun nails.
[0046] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
