Description

Изобретение относитс к строительству , судостроению и авиастроению. FIELD OF THE INVENTION The invention relates to construction, shipbuilding, and aircraft building.

По основному авт. св. № 781291 известна многослойна чеиста панель, состо ща из обшивок и среднего сло , выполненного из листового материала в виде структуры чеистого типа, с выступами, представл ющими собой многогранные усеченные пирамиды, расположенными во взаимно перпендикул рном, направлении по отношению к плоскости основани . По кра м панели выполнено торцовое обрамление в виде швеллера, полки которого содержат складки, повтор ющие сечение канала, образованного соседними р дами выступов, вертикальнре ребро содержит продольные пазы или выступы С1 }.According to the main author. St. No. 781291 is a known multi-layer cellular panel consisting of skins and a middle layer made of sheet material in the form of a cellular type structure, with protrusions representing multi-faceted truncated pyramids located in a mutually perpendicular direction relative to the base plane. Along the edges of the panel, there is an end frame in the form of a channel, the shelves of which contain folds that repeat the section of the channel formed by adjacent rows of protrusions; the upright edge contains longitudinal grooves or protrusions C1}.

Однако при соединении двух панелей или панели с конструкционными элементами прочность соединительного шва низка . Это объ сн етс малой площадью соединени торцового обрамлени , а также отсутствием конструктивногоHowever, when two panels or panels are joined with structural elements, the strength of the connecting seam is low. This is due to the small joint area of the edging, as well as the lack of constructive

элемента, включающего в работу не только торцовое обрамление, но и заполнитель смежной панели.element, which enters into the work not only the face frame, but also the filler of the adjacent panel.

Целью изобретени вл етс повышение прочности и технологичности соединени панелей между собой и конструктивными элементами.The aim of the invention is to increase the strength and manufacturability of the connection of the panels between themselves and structural elements.

Указанна цель достигаетс тем, что в многослойной чеистой панели торцовое обрамление выполнено с кон10 солью в виде пластины с продольными армирующими элементами, конгруэнтными по форме каналам между р дами выступов заполнител .This goal is achieved by the fact that in a multilayer cellular panel, the end frame is made with a salt in the form of a plate with longitudinal reinforcing elements congruent in shape to the channels between the rows of filler projections.

На фиг. 1 изображена многослой15 на чеиста панель, общий вид, аксонометри ; на фиг. 2 - то же, торцового соединительного элемента.FIG. 1 shows a multilayer 15 on a mesh panel, general view, axonometric; in fig. 2 - the same, the face connecting element.

Claims

20 2, made of sheet material in the form of a cellular type structure with hollow protrusions 3, for example, in the form of a truncated octahedral pyramid 3 MIDA. The protrusions 3 of the filler 2 are formed by the side faces and the plane of the section 5 which is the contact surface. The lateral faces of the protrusions are limited by the base plane 6. Adjacent projections 3 of the filler 2 are directed by their vertices opposite sides of the base 6. The end edge of the panel 7 is made. It is an element of the channel type, the horizontal shelves 8 of which are in the form of folds 9. and the vertical edge 10 contains grooves 11 and protrusions 12. Vertical edge 10 of the edge frame 7 passes into the console 13, which is a plate with longitudinal closed projections Ti, a trapezoidal section and The device works as follows. The trapezoidal folds 9 of the horizontal shelves 8 of the edge framing 7 enter the channels formed by the projections 3 of the filler 2 and are connected to them by lateral and horizontal edges. The casing 1 is connected with the filler 2 along the contact surfaces of section 5 and the horizontal shelves 8 of the end frame 7, and the casing 1 is shifted from each other. The panels are interconnected by inserting the longitudinal elements located on the console of one panel into the longitudinal channels formed by the folds of the horizontal flanges of the edge framing. A multi-layer mesh panel is made. The skins, filler and front bezel are made of fiberglass on the basis of glass4 T-10 fabric and binder EF-32-331. The face frame is molded on a special mold of two layers of fiberglass. The bonding of the skins to the aggregate, the edge framing, and the interconnection of the panels with each other are carried out using an epoxy resin adhesive composition. The proposed construction of a multilayer cellular panel has good mechanical characteristics, especially in the marginal zones, and also has good processability of connecting panels to each other. Performing a console with longitudinal reinforcing elements makes it possible to make a connection with the separation of the joint from the end of the panel. In addition, a filler is included in the work through the horizontal flanges of the end frame. The shifted skins overlap the junction and contribute to improving the mechanical characteristics of the panel. Claims of the Invention Multiple Cellular Panel according to the ed. St. ff 781291, characterized in that, in order to increase the strength and manufacturability of the connection of the panels, the end frame is made with a console in the form of a plate with longitudinal reinforcing elements congruent in shape to the channels between the rows of filler projections.
