[0055] Example 1
[0056] Please refer to Figure 1-8 As shown in the drawings, the embodiment provides a support structure for an indoor door and an indoor door, comprising an indoor door 100, which is provided with a frame 10, the frame 10 comprises a reinforcing frame 101, the reinforcing frame 101 adopts a plurality of groups of solid wood boards to combine to form a quadrilateral frame, and the reinforcing frame 101 is provided with reinforcing ribs 102 integrated therein, the reinforcing ribs 102 comprise longitudinal reinforcing ribs and transverse reinforcing ribs, the storage cavity in the reinforcing frame 102 is divided into four groups of cavity 104 for placing the support structure 40 by the longitudinal reinforcing ribs and the transverse reinforcing ribs, and the support structure 40 is installed on the inner wall of the reinforcing frame 101 by a fixed connection mode such as fastening screws or adhesion; the support structure 40 is located between two groups of door panels 50, and a closed reinforcing cavity is formed between the support structure 40 and the door panels 50, and the support structure 40 is respectively installed on the two groups of door panels by a hot pressing process.
[0057] During installation, only need to spray glue on the support structure 40, then place two groups of door panels 50 on both sides of the support structure, and then realize the connection between the door panels and the support structure by a hot pressing process, so that they are integrally arranged. Compared with a cold pressing process, the hot pressing process can greatly improve the work efficiency.
[0058] Further, the longitudinal reinforcing ribs extend along the longitudinal direction of the door panel 50 and intersect with the transverse reinforcing ribs extending in the transverse direction of the door panel, so that the reinforcing ribs are integrally arranged in a cross shape; the width of the transverse reinforcing rib and the longitudinal reinforcing rib is 41 mm, the length of the longitudinal reinforcing rib is 1970 mm, and the length of the transverse reinforcing rib is 620 mm.
[0059] In actual application, since the existing indoor door all takes honeycomb copper plate paper as the internal support skeleton, the thickness of the copper plate paper is 0.03mm-0.08mm. The thickness is too thin to adhere glue. During production, the glue needs to be brushed manually to the inner side of the inner and outer door skins, and then the honeycomb copper plate paper is laid, which is not high in production efficiency. In order to solve the above technical problems,
[0060] The support structure 40 comprises a plurality of groups of independently arranged support units 401, and each group of independently arranged support units 401 comprises two groups of support plates 4011 spliced together, so that the inside of the support unit 401 is arranged in a hollow structure, and the middle part of each group of support plates is provided with a bent end 403.

[0063] Further, at least one set of heat dissipation grooves 103 is arranged on the lateral frame of the reinforcing frame 101, and the heat dissipation grooves 103 are uniformly distributed along the lateral frame of the reinforcing frame 101. When connected by the heat pressing process, the heat dissipation grooves 103 facilitate heat dissipation, thereby reducing the probability of cracking caused by gas expansion in the sealed space.
[0064] In the embodiment, the support structure 40 is formed by the combination of the wave-shaped support plates 4011 with a thickness of 3 mm. Compared with the traditional honeycomb copper paper board material, the thickness and rigidity are higher, and by arranging the bending end 403 on each set of support plates 4011, the support structure 40 formed by the combination of the wave-shaped support plates 4011 can effectively disperse the stress caused by heat pressing, avoid the local stress concentration, and thus avoid the cracking problem of the traditional honeycomb copper paper support structure caused by gas expansion in the sealed space, thereby improving the production efficiency and ensuring the quality of the finished product.

By adding the die density board 60, the storage cavity in the reinforcing frame 102 is divided into eight cavities 104 for placing the support structure 40; and the support structure 40 in the cavities of the two side end faces of the die density board 60 is closely attached to the die density board 60 and the door plate.

[0070] In the embodiment, the arc-shaped supporting plate is additionally arranged, so that the molded density board 60 is conveniently clamped and installed in the frame 10, and when being installed, the molded density board has a certain elastic allowance, so that the molded density board is conveniently clamped. The molded density board is additionally arranged, so that the strength of the door body is improved, and since the molded density board is arranged in the frame, the door body has a proper thickness and improved strength. Since the door plate is made of solid wood plate, when the external environment (temperature and humidity) changes, the wood plate expands or shrinks unevenly, and internal stress is generated. The spring is additionally arranged, so that the spring is used to absorb the stress generated by the door plate due to the change of the external environment (temperature and humidity), so that the deformation resistance of the door plate is improved.
[0071] When being installed, the through groove of the molded density board is arranged opposite to the reinforcing rib, and then the molded density board is pressed, so that the reinforcing rib automatically passes through the through groove of the molded density board, and at this time, the clamping piece 901 of the molded density board is automatically clamped into the clamping groove, so that the clamping connection is realized, and the fastening connection between the molded density board and the frame 10 is realized, and the installation of the molded density board is completed.
[0072] In the embodiment, the molded density board is additionally arranged, so that the overall strength of the indoor door is improved.
