Board connection structure

Abstract

The invention relates to a board connection structure, which is applied to decorative sheets and building materials. An upper edge end and a lower edge end are fixed on one side of a board A, the upper edge end approaches to the front side of the board A, and the lower edge end approaches to the back surface of the board A; a butt joint hole is formed in one side of the board A and is positioned between the upper edge end and the lower edge end; an upper edge butt joint end, a lower edge butt joint end and a base are fixed on one side of a board B, the upper edge butt joint end approaches to the front side of the board B, the base approaches to the back surface of the board B, and the lower edge butt joint end is positioned between the upper edge butt joint end and the base; the lower edge butt joint end is in clearance fit with the butt joint hole; when a concave shape butt joint end and a convex shape butt joint end are spliced, the lower edge butt joint end is inserted into the butt joint hole, the upper edge butt joint end and the upper edge end are opposite, and the lower edge butt joint end and the base are opposite; the overlapping part of the lower edge butt joint end and the base is provided with a nailing position; the upper edge end is wider than the lower edge end. The board connection structure has the advantages of low rejection rate, long service life, low cost and good effect.

Description

Technical field [0001] The invention relates to a board connection structure, which is applied to decorative panels (walls, suspended ceilings, exterior wall facades, partitions, door panels, floors, etc.) and building materials (hollow sealed walls, sound-absorbing panels, fireproof and anti-radiation laminates, stone materials, etc.) )in. Background technique [0002] As shown in the Chinese patents owned by Zhejiang Pute Sunshine Board Co., Ltd., such as the patent numbers 201220338846.2 and 201120320215.3, the prior art board connecting structure of decorative panels and building materials is divided into A board and B board, A board and B board The shapes are the same, and they match each other. [0003] A concave docking end is provided on one side of the A board. The concave docking end includes an upper edge end (ie, the lower bottom surface 33 in the Chinese patent with patent number 201220338846.2) and a butting interface (ie the groove in the Chinese patent with patent ...

AI Technical Summary

Problems solved by technology

[0014] Since the nailing position is set on the lower edge end, in order to ensure the strength, the lower edge end needs to have a certain thickness, so the thickness of the upper edge end needs to be sacrificed, and due to the limitation of the structure itself, the upper edge end, the upper edge butt end, and the lower edge end , The lower edge butt joint can not be made thicker, generally only 10%-20% of the overall height ratio, it is easy to be damaged during installation and transportation, especially the lower edge is easy to break during production and produce waste products; and in the During the installation, it needs to be nailed and fixed on a specific building surface such as the wall, which greatly increases the scrap rate. Therefore, the manufacturer only needs to add an additional set of equipment and use high-frequency mutual aid technology to strengthen the lower edge, and the installer generally can only purchase it. Increase the spare amount in advance to prevent excessive waste from delaying the construction period or shoddy and shoddy use during installation

[0015] In field application, walls, floors and other building surfaces will have varying degrees of height and inclination, which will cause problems such as uneven board surfaces and loose joints during the docking process.

The original plate connection method, due to the limitation of the structural thickness of the upper edge end and the upper edge butt end, it is impossible to thicken the process, adjust the seam during installation and construction, and can only add decorative strips at the seam (currently Mainly I-shaped metal profiles, lacquered wood), waste work and waste, and easy to fall off and damage

[0016] It can be seen that this structure has the disadvantages of high scrap rate, short service life, high cost and poor effect
