The invention discloses a carriage plate connecting structure which comprises an edge covering profile and a carriage plate, an embedding groove is formed in the edge covering profile, the carriage plate is connected with the embedding groove in a sleeved mode, the end of the carriage plate is bonded with the edge covering profile, a framework is arranged in the carriage plate, one side of the carriage plate is fixedly connected with a clamping opening formed in the edge covering profile through the framework, and the other side of the carriage plate is bonded with the edge covering profile. A carriage plate connecting method comprises the steps of structural adhesive coating, bayonet proofreading, inserting plate mounting and the like, a bayonet is formed in the contact face of an edge covering profile and one side of a carriage plate, a framework in the carriage plate is connected with the bayonet in a matched mode, an inserting plate profile is arranged on the other side of the carriage plate, and the bayonet of the inserting plate profile and a tooth-shaped contact face can be used for increasing the contact area. By means of interference fit connection of the inserting plate sectional materials, the edge covering sectional materials can be matched with box plates of different sizes, meanwhile, machining errors are eliminated, the attaching degree of the edge covering sectional materials and the box plates is improved, the contact faces of the box plates and the edge covering sectional materials can be bonded after structural adhesive is coated, the inertia moment of a connection section is increased, and the connection strength and the overall rigidity are improved.
本发明公开了一种车厢板连接结构,包括包边型材、箱板,包边型材内设置有嵌槽,箱板与嵌槽套接,箱板端部与包边型材粘接,箱板内设置有骨架,箱板一侧通过骨架与包边型材设置的卡口固定连接,箱板另一侧与包边型材粘接;一种车厢板连接方法,包括涂覆结构胶、卡口校对、插板安装等步骤,包边型材与箱板一侧的接触面设置卡口,箱板内的骨架与卡口配合连接,另一侧设置插板型材,插板型材的卡口与齿状接触面可以用于增大接触面积,通过插板型材的过盈配合连接,可以适配多种不同尺寸的箱板,同时消除了加工误差,提高包边型材与箱板的贴合程度,涂覆结构胶后可以粘接箱板与包边型材的接触面,提高连接断面的惯性矩,提高连接强度和整体刚度。
