Description

The field of technology

The technical solution concerns load-bearing structures, especially for residential and commercial vehicles, which consist of transverse ribs and longitudinal beams, their anchoring and cladding.

Current state of the art

Various solutions for anchoring furniture and equipment to vehicles are known from technical practice. Normally and most often, furniture and equipment are anchored directly to the vehicle body. The disadvantage of this solution is the early susceptibility to creaking of the furniture due to the twisting of the body, few anchor points, and therefore a high susceptibility to tearing out the furniture and equipment in an accident, which can endanger the vehicle crew. In addition, it is necessary to use relatively thick materials, usually 15 mm thick poplar plywood, to reinforce the furniture to make it as resistant as possible against being pulled out. The use of such a coarse material brings with it other disadvantages, such as an increase in the weight of the vehicle, deterioration of driving characteristics, especially longer braking distance, slower response of the vehicle to a change in direction of travel, increase in the center of gravity of the vehicle, increase in fuel consumption, greater wear of the brake lining and others that are related with a higher vehicle weight. The low strength of poplar plywood and its relatively high weight at the commonly used thickness of 15 mm result in easy loosening of joints or complete tearing under increased load, for example in the event of unevenness on the road, traffic accident, etc.

Another form of anchoring furniture and equipment is the use of spacers made of plywood or raw boards, which are anchored to the bodywork. In practice, this means riveting, screwing, or even just fixing with screws to the load-bearing structures of the body.

All these forms of anchoring have a common disadvantage in the small number and distribution of anchor points due to the weight of the subsequent installation and the easy transfer of torsion to furniture and equipment. It is known from practice that, for example, only load-bearing body parts are used for anchoring, to which cover plates and furniture are then anchored. From this point of view, it is obvious that a large space must be lined with a thick material so that it does not bend and can also hold the installed furniture, for example upper cabinets.

The essence of the technical solution

The above-mentioned shortcomings are largely eliminated by the construction, especially for anchoring furniture and equipment in residential and commercial vehicles, according to this technical solution. Its essence consists in the fact that it consists of ribs located in the vertical direction according to the shape of the inner surface of the vehicle's storage space, which on the side facing the surface of the vehicle are equipped with a recess for the inner supporting structure of the vehicle and are further equipped with connecting elements to connect them to the inner supporting structure vehicles.

The connecting elements are preferably L-shaped profiles, which are connected to the internal structure of the vehicle by a connection selected from the group of glued, welded, riveted, screwed and soldered connections and screwed to the ribs.

The ribs can be equipped with additional recesses for beams in the horizontal direction on the side facing the interior of the vehicle. Ribs and beams can be equipped with relief holes.

Ribs and beams in the horizontal direction are usually made of waterproof birch plywood, which copies the internal shape of the body, including the internal structure of the supporting parts of the vehicle. The ribs can be adjusted to suit the shape of the interior space, including removing parts of the ribs, for example to allow the bed to be installed across the space to increase the width of the bed. Mechanically better properties of the rib structure are achieved by using materials such as aluminum, its alloys, carbon or carbon-kevlar composites and others. The anchoring of the rib structure is most often done using aluminum "L" profiles and their alloys, which are glued with a polyurethane (PU) structural adhesive and then riveted to the internal supporting structure of the vehicle body. For ribbing, a suitable type of joint is used according to the material of the ribs used, for example, with plywood ribs, screws or a screw joint are used through all layers. Anchor points are always used in all accessible surfaces to distribute the forces as much as possible. The use of "L" profiles for anchoring is justified by unstable shapes, i.e. j. manufacturing deviation of the vehicle body. Thanks to the larger contact area between the "L" profile and the ribs, the ribs can be moved freely in all axes to achieve the exact dimensions for the subsequent assembly of furniture and equipment. Horizontal beams, which are embedded in the ribs, connect all the ribs to each other, giving the entire structure rigidity and more anchor points for the subsequent installation of paneling, furniture and equipment.

The advantages of the presented technical solution mainly consist in the strengthening of the vehicle structure, i.e. j. in a lower degree of twisting of the body and in a higher number of anchor points for furniture and equipment. Another advantage is the possibility of using light composite and sandwich cladding boards or thin plywood boards with lower overall weight, stronger joints and better overall stiffness. Ribbing and horizontal beams can be lightened by means of holes in such an amount that the required strength of the whole is maintained. Another advantage of finning is that air can circulate between the thermal insulation of the vehicle body and the vehicle lining, which significantly reduces the formation of condensate on the vehicle walls. It only applies in the case of heating and ventilation in the vehicle, i.e. j. mostly for caravans.

Overview of images on drawings

The structure for anchoring furniture and equipment of residential and commercial vehicles according to this solution will be described in more detail on a specific example of implementation using the attached drawing, where in fig. 1 shows part of the structure on the inner wall of the vehicle's storage space.

Implementation examples

An example of a ribbed construction for residential and commercial vehicles shown in fig. 1 consists of vertical ribs 1 and horizontal beams 6. Ribs 1 are anchored at predetermined locations using fasteners 5 in the form of aluminum "L" profiles to the supporting parts of the internal supporting structure 3 of the vehicle body. The "L" profiles must be glued with PU or other vibration-resistant structural adhesive and riveted to the bodywork with stainless steel rivets of 4 mm diameter or more, at least in two places of each "L" profile. The number and diameter of rivets is always dimensioned according to the required strength in a given position. The profile is anchored to rib 1 with screws or bolts through the entire structure. If the gap between the inner surface 2 of the body and the rib 1 is within 10 mm, it can be filled with PU or other anti-vibration glue to further increase the strength and durability. After mounting the ribs 1, they are tied with longitudinal beams 6 inserted, glued and anchored with screws or bolts through the entire structure. In order to achieve the same result in all vehicles and the possibility of mass production, mounting templates are used to ensure the same position of the ribs 1 against each other in all directions. Then follows the anchoring of furniture, equipment and covering surfaces to the created structure.

With the help of this technology, we managed to produce a very solid living space that shows no signs of wear or creaking even after a year of use, the individual seats do not bend as in normal installations and meets the weight limits of up to 3.5 tons even when fully occupied by six adults per ride and sleeping.
