Description

Technical Field

[0001] The utility model mainly relates to the field of extra-wide doors, and particularly relates to a splicing structure of an extra-wide door with a multi-cavity skin-foaming door above 1180. Background Art

[0002] For the ward doors in some areas, the width is designed to reach 1.3 meters to ensure that the hospital bed can pass through smoothly. And the traditional double-leaf doors are gradually replaced by extra-wide door leaves, and extra-wide doors will become a trend in the future design of interior doors in public places;

[0003] Except for steel doors, the multi-cavity skin-foaming resin doors have a fire protection rating above B1 and become the first choice for doors used in public places. However, whether it is a traditional wood-plastic door, it is generally formed by extrusion in one step, which means that the width of the door leaf is fixed at 1.1 meters.

[0004] During the operation of specific embodiments, the inventor found the following defects:

[0005] It is very difficult for the resin door formed by extrusion to exceed a width of 1100 mm. Beyond this width, it is very difficult to control both the processing difficulty and the deformation of the door panel. Therefore, when the resin door is used in door openings above 1100, the double-leaf door method is mostly used for opening and closing, and it cannot be adapted when using a single door leaf, resulting in limitations in engineering use.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and extremely complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0007] 1. Technical problems to be solved by the utility model:

[0008] The utility model provides a splicing structure of an extra-wide door with a multi-cavity skin-foaming door above 1180 to solve the technical problems existing in the above background art.

[0009] 2. Technical solution:

[0010] To achieve the above purpose, the technical solution provided by the utility model is: a splicing structure of an extra-wide door with a multi-cavity skin-foaming door above 1180, including a mother door body, a sub-door body is arranged on one side of the mother door body, cavity bodies are opened inside the mother door body and the sub-door body, and a connection structure is arranged between the cavity bodies;

[0011] The connection structure includes a fixed wooden wedge, structural adhesive bodies are arranged on both sides of the fixed wooden wedge, the structural adhesive bodies are connected with the cavity bodies, and fixed long nails are arranged inside the structural adhesive bodies.

[0012] Further, the structural adhesive body is installed inside the cavity body at the connection position of the mother door body and the child door body.

[0013] Further, a decorative strip is provided between the mother door body and the child door body, and the decorative strip is attached to the fixed wooden wedge.

[0014] 3. Beneficial effects:

[0015] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0016] The overall splicing method of the mother door body, the connection structure and the child door body of the present utility model adopts a concave + convex + concave wedge-shaped splicing method. Two door leaves are spliced in the long direction according to one large and one small. When choosing the width of the two door leaves, comprehensive calculations are carried out from aspects such as aesthetics, the center of gravity load-bearing position, and the joint load-bearing position. Different sizes of the mother door body and the child door body can be adopted according to the use requirements. In this way, it can ensure that the width of the spliced child door is controlled within 500 mm and the weight is controlled at about 10 kg.

[0017] After splicing, there will be a splicing joint of about 3 mm between the mother door body and the child door body. To ensure the overall beauty and coordination of the door leaf, for the foamed skin board, a 3-mm standard groove is opened at the joint with a grooving tool, and after filling this part with ordinary adhesive, a 3-mm PVC decorative strip is installed. This treatment method is both beautiful and has a certain artistic sense, and is easily accepted by customers. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Referring to the attached Figures 1-3 , a splicing structure for a multi-chamber skin-foaming door with a width exceeding 1180, including a mother door body 1, a sub-door body 2 is arranged on one side of the mother door body 1, a cavity body 3 is opened inside the mother door body 1 and the sub-door body 2, and a connection structure is arranged between the cavity bodies 3;

[0028] Connection structure, which includes a fixed wooden wedge 5. Structural adhesive bodies 4 are arranged on both sides of the fixed wooden wedge 5. The structural adhesive bodies 4 are connected to the cavity body 3. A fixed long nail 6 is arranged inside the structural adhesive bodies 4. The connection method of cavity body 3 + connection structure + cavity body 3 is adopted, and the cavity body 3 is concave. Cut 1 / 3 of the first cavity body 3 of the mother door body 1, and retain 2 / 3 of the cavity body 3. The child door body 2 selects the cavity body 3 according to the size. In principle, the retained part of the cavity body 3 is not less than half of the original cavity body 3. Make the fixed wooden wedge 5 according to the splicing cavity size of the mother door body 1 and the child door body 2. The length of the fixed wooden wedge 5 is 1 mm greater than the sum of the two spliced cavities. First, fill about 1 mm thick of the structural adhesive body 4 between the fixed wooden wedge 5 and the cavity body 3 inside the mother door body 1. After filling the fixed wooden wedge 5, use a fixed long nail 6 not less than 40 mm to screw and fix from one end, and ensure that the fixed long nail 6 penetrates at least the internal rib of one cavity body 3. This ensures the structural strength between the cavity body 3 and the mother door body 1. After completion, let it stand for about 10 minutes to ensure that the adhesion of the cavity body 3 reaches the best. Then, cover the remaining cavity body 3 of the child door body 2 with 1 mm of the structural adhesive body 4. Buckle the child door body 2 on the fixed wooden wedge 5 and let it stand for 10 minutes. At this time, there is about a 3 mm splicing seam between the mother door body 1 and the child door body 2.

[0029] Furthermore, the structural adhesive bodies 4 are installed inside the cavity body 3 at the connection position of the mother door body 1 and the child door body 2. A decorative strip 7 is arranged between the mother door body 1 and the child door body 2. The decorative strip 7 fits with the fixed wooden wedge 5. After splicing, there will be about 3 mm splicing seams on both the inner and outer sides of the mother door body 1 and the child door body 2. To ensure the overall beauty and coordination of the door leaf, for the joint of the mother door body 1 and the child door body 2, use a grooving tool to open a 3 mm standard groove at the joint. After filling this part with ordinary adhesive, install a 3 mm PVC decorative strip 7. This treatment method is both beautiful and has a certain artistic sense, and is easily accepted by customers.

[0030] The mother door body 1 has widths of 680 mm, 780 mm, 880 mm, and 980 mm. According to the load-bearing position, in principle, for door leaves with widths of 1100 mm - 1300 mm, the mother door body 1 with a width of 880 mm + a child door body 2 with a width of 220 mm - 420 mm should be selected for splicing. For door leaves with widths of 1300 mm - 1400 mm, 980 mm + 320 mm - 420 mm should be selected for splicing.

[0031] The above-described embodiments merely represent certain implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
