RU2223884C1 - Method of assembling van-type body from sandwich panels - Google Patents

Abstract

FIELD: transport engineering. SUBSTANCE: proposed method of assembling van-type body comes to making sandwich panels are mounted forming side, front and rear panels of body. Sandwich panels are made up of outer cover plate, inner cover plate made of foamed plastic providing heat insulation, and embedded member designed for fastening mounted equipment both from outside and inside of body and assembling of panels to form roof and bevels. Sandwich panels are essentially glued panels whose outer cover plate is 27 mm thick, and they consist of plastic laminated and plywood, 4 mm thick, to increase rigidity of panels. Embedded member is made of birch plywood, 27 mm thick, and frame is made of metal sections and wood flooring secured of frame. Sandwich panels are fastened of frame by means of aluminum angle plates 9 onto which flue composition 12 is applied. Roof, bevels and side panels are connected by glue and rivet joints through aluminum angle plates. EFFECT: reduced labor input and mass of load bearing structure, improved reliability. 5 dwg

Description

 The invention relates to the field of mechanical engineering, mainly to transport and specialized, and relates to a method of assembling a van type body.

 A known method of manufacturing a body of individual small interchangeable facing elements of a given shape, which are mounted on a frame frame (patent RU 2048350). At the same time, the replaceable elements are small and are assembled together in the form of body cladding panels, i.e. determine its shape.

 The disadvantages of this method are the fastening of elements to the support frame, which describes the desired section of the body using adhesive bonding, which leads to a decrease in the strength and build quality of the body, as well as the use of small interchangeable cladding elements of a given shape only in the automotive industry.

 There is a method of assembling a van body from individual panels, which consists in the manufacture of sandwich panels and a frame, which are attached to form the side, front and rear body panels, sandwich panels consisting of an outer skin, an inner skin made of foam, providing thermal insulation , and a mortgage element designed to attach attachments both outside and inside the body, and to assemble the panels that make up the roof and bevels (EP 0017263 A1, 10/15/1980).

 The disadvantages of this method are low thermal insulation, increased sound permeability, corrosion of the structure due to poor tightness, increased weight due to the large amount of metal, the large complexity of manufacturing the body.

 The technical result of the invention is to reduce the complexity of assembling a van type body due to technology based on non-welded production, providing sound insulation, reducing the weight of the supporting structure, reducing corrosion due to the tightness of the structure, as well as the possibility of using this body for its various purposes.

 This is achieved by the fact that a wagon-type body is proposed, assembled from separate sandwich panels (C-P), of the required size and shape, connected to each other depending on their design purpose using self-tapping screws, glue, rivet, bolt joints.

Figure 1-5 shows the proposed box body type:
figure 1 - General view of the body of the van type;
figure 2 is a section aa in figure 1;
figure 3 is a section bB in figure 1;
figure 4 is a section bb in figure 1;
figure 5 - section GG in figure 1.

 The term "sandwich panel" 1 in the present invention refers to a glued panel with a cross section of 40 mm, consisting of elements including an outer skin 2 made of a duralumin sheet; an inner lining made of foam plastic 3 with a thickness of 27 mm, providing thermal insulation, a plastic laminate 4, reinforcing the structural rigidity of plywood 5 with a thickness of 4 mm, as well as a mortgage element made of birch plywood 6 with a thickness of 27 mm, designed to attach attachments both outside and inside bodywork.

 The method of assembling a van type body from S-P is as follows.

 First, a frame is made of metal profiles 7 and a wooden flooring 8 fixed to it (Fig. 3), onto which C-P 1 is fastened around its perimeter using aluminum corners 9 with a rivet connection 10 outside the body and with self-tapping screws 11 and a rivet connection 10 inside the body, forming the side, front and rear panels of the van type. To ensure the tightness of the wagon body assembly structure, an adhesive joint 12 is applied to the aluminum corners 9. To ensure structural rigidity, a bolted joint 13 is used around the entire perimeter of the frame.

 The assembly of the remaining panels constituting the roof 14, bevels 15 and side panels 16 is carried out using aluminum corners 9 with adhesive 12 and rivet 10 joints (Fig. 4).

 Attachments are attached to the body of the van type with a special self-tapping screw with a hexagonal head 17 in the embedded element 6 (figure 5).
