Abstract
The utility model is composed of two or more than two blocks of multi-layer plywoods with small size which are engaged. The contiguous part of each multi-layer plywood block with small size is provided with a cambered tooth. The two ends of the middle multi-layer plywood block connected with the middle part are provided with the cambered teeth and the number of the middle multi-layer plywood block can be increased. The utility model has the advantages that short material is used for long-use purpose, the wood using rate is increased, the applying ranges of the multi-layer plywood are enlarged, etc.
Description
The utility model belongs to the passenger train carriage multi-plywood, relates to the further improvement to existing multilayer gluing plated construction.
At present, the main breadth specification of multi-plywood that domestic plywood factory produces is 915mm * 1830mm, 1220mm * 2135mm, 1220mm * 2440mm, and up to the present the lengthening veneer of a few manufacturer production length greater than 2440mm only arranged.Utility model patent " lengthening veneer " 98238409.2, be after having process equipment now and improving the veneer of each layer veneer to be come together, can be processed into the lengthening veneer, but owing to be subjected to production technology, device-restrictive, its maximum extension length is only in 3000mm.And can not widen simultaneously.Therefore be difficult to satisfy some special requirement dimensional requirements of passenger train carriage.
The purpose of this utility model provides and a kind ofly extends simultaneously, widens and length is the large format multi-plywood of choosing arbitrarily, satisfies the requirement of passenger train carriage to the special size multi-plywood, enlarges the range of application of multi-plywood.
Characteristics of the present utility model are made up of the small-scale multi-plywood of two or two above same thickness, at multi-plywood adjacent open arc shape tooth, since multi-plywood can the single face tooth punching also can two-sided tooth punching and buttcover plate quantity unrestricted, therefore spreading plate face length degree can be chosen arbitrarily, extends simultaneously, former composite board length can be become the width tooth punching when widening and can produce lengthening, widen multi-plywood as need.End face toe joint characteristics are that bonding strength height, supporting capacity are big, and anti-deformation is good.
Good effect of the present utility model is to be made of polylith small breadth multi-plywood toe joint, can realize the long usefulness of short material, improves timber utilization rate, enlarges the multi-plywood range of application, except that being used for the passenger train carriage plate, also can be used for the deck of boat and building trade.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model toe joint multilayer gluing plate toe joint structural principle schematic diagram.
Fig. 2 is the utility model tooth-connecting elongating multi-plywood toe joint structural representation.
Fig. 3 is the utility model tooth-connecting elongating, widen the multi-plywood structural representation.
At Fig. 1, among Fig. 2 and Fig. 3, the 1st, the multilayer gluing plate, the 2nd, middle multilayer gluing plate, the 3rd, the multilayer gluing plate, between multilayer gluing plate 1 and multilayer gluing plate, at least multilayer gluing plate 2 in the middle of connecting, be respectively arranged with arc tooth 5 and arc tooth 6 in the both sides of multilayer gluing plate 2, right-hand member at multilayer gluing plate 1 is provided with arc tooth 4, the left end of multilayer gluing plate 3 is provided with arc tooth 7, with multilayer gluing plate 1, middle multilayer gluing plate 2, multilayer gluing plate 3 is by arc tooth 4 and arc tooth 5, arc tooth 6 and 7 toe joint successively constitutes one.Accompanying drawing 2 is middle structural representations that connect the middle multi-plywood of 2 small-sizeds, can remove middle multilayer gluing plate 2 according to the length specification needs, the quantity of multilayer gluing plate 2 in the middle of also can increasing, and can reach the purpose of lengthening by any spreading of length direction.In the time of need removing centre multilayer gluing plate 2, multilayer gluing plate 1 and multilayer gluing plate 3 are constituted one by arc tooth 4 and arc tooth 7 direct toe joints.In the accompanying drawing 3, when needing lengthening, can be in the length direction open arc shape tooth butt joint of small-sized multilayer gluing plate, small-sized multi-plywood length dimension becomes toe joint multi-plywood width dimensions, can reach simultaneously the purpose that extends, widens.
