Technical Field

The invention according to the application relates to an insulated embedded floor that forms the trailer floor of vehicles which carry perishable food and cargo and thereby whose trailers are insulated.

The State-of-the-Art (Prior Art)

According to the prior art, the floor section of trailers of vehicles, which carry perishable food and cargo and thereby whose trailers are insulated, that are connected to the vehicle chassis consist of wooden crosses, a CTP panel or an aluminium panel, an isolation block, plywood flooring, and an upper panel made of chequered aluminium.

The most important problem of this floor structure that is in use today is that in order to attach the structure to the vehicle chassis, a second support chassis is bolted under it and then the floor assembly is mounted to the vehicle chassis.

In such applications, the floor structure should have a minimum height of 60 mm for it to compensate the loads and forces exerted on it and due to the structure of the king pin located on the lower support chassis. Consequently, the net height for inner loading is kept at a low value in order not to exceed maximum clearance limits according to regulations. This, in turn, reduces the vehicle's load capacity and efficiency.

Brief Description and Aims of the Invention

With the insulated embedded floor according to the invention, minimisation of the support chassis structure's height by reinforcing the floor structure and thereby production of a vehicle with more inner height are aimed by using profiles with custom cross-section made of high strength steel, coupling elements and ducts, embedded draw pin design and countersunk bolt connection systems unlike prior art floor systems.

The invention according to the application is an insulated embedded floor (13) that forms the trailer floor of vehicles which carry perishable food and cargo and thereby whose trailers are insulated, which consists of

· At least four frame profiles (7) that forms the support frame for the embedded floor (13),

• At least four support profiles (1) that bridge the frame profiles (7) and comprise at least three coupling elements (11) and at least two U formed plates (12),

• At least two cable groves (3) that traverse the support profiles (1),

· A lower plate (2) that is placed on the inner section of the support frame formed with the frame profiles (7) and consists of one or more than one plates,

• At least five insulation blocks (4) that provides primarily heat insulation as well as sound and moisture insulation and placed on the lower plate (2) in such a manner that they fill the spaces among the frame profiles (7),

· A plywood floor (5) that is positioned in such a manner that it covers the insulation blocks (4) and consists of one or more than one plates,

• An upper plate (6) that is positioned in such a manner that it covers the plywood floor (5) and consists of one or more than one plates,

and minimises the support chassis structure's (8) height due to its high strength property.

The embedded floor (13) according to the invention is formed by joining all of the aforementioned parts by using adhesive on the joining points and then adhering them together by pressing under high pressure and then it is mounted on the support chassis (8) through the draw pin (10) with the help of at least four countersunk bolts (9).

While the frame profiles (7) are steel in the basic embodiment of the invention, they may be made of any other metal or plastic in different embodiments of the invention.

While the support profiles (1) are steel in the basic embodiment of the invention, they may be made of any other metal or plastic in different embodiments of the invention.

The number of U formed plates on each support profile (1) is one for each cable groove (3), depending on the number of cable grooves (3) that are used on the embedded floor (13).

While the cable grooves (3) are steel in the basic embodiment of the invention, they may be made of any other metal or plastic in different embodiments of the invention. While the lower plate (2) is CTP in the basic embodiment of the invention, it may be aluminium or metal sheet panel in different embodiments of the invention.

While the insulation blocks (4) are EPS or XPS, PU foam in the basic embodiment of the invention, they may be made of any insulation material in solid phase.

While the upper plate (6) is aluminium in the basic embodiment of the invention, it may be epoxy plating in different embodiments of the invention.
