Author of the invention SZÉKELY PETR ing. And SEVC1K MIROSLAV, Prague (54) Through-channel mounted channel especially for energy purposes 1? ,

The invention relates to a pass-through. prefabricated de-sec.

The hitherto known energy channels are assembled from prefabricated parts of relatively complex shapes. They are either blocks of a completely enclosed rectangular cross section or a U-shaped profile, covered by cover plates or opposed L-shaped blocks, which are again covered by plates. Also known are channels formed by circumscribing vertical and horizontal plates. The common disadvantage of these known embodiments is that they impose increased costs on the manufacture, storage, transport, and possibly assembly of prefabricated parts and thus become uneconomical.

The aforementioned disadvantages are substantially reduced by the through-mounted duct, in particular for energy purposes, from prefabricated panels according to the invention. Its essence is that its wall parts and ceiling and bottom parts are assembled with the relative displacement of the contact surfaces and their outer reinforcement is welded together by supporting welds to form rigid joints. Its prefabricated plates, that is, the wall and ceiling parts and the bottom can be made of ceramic hollow inserts and iron-concrete. Outer reinforcement from ceiling and bottom parts, (51) Int. Cl.5E 02 D 29/12 ‘2 protruding from the rebates at their edges, should not exceed the total thickness of the compartment. The external reinforcement can be welded together by means of steel plates embedded in the wall parts. The steel plates are welded to the main reinforcement, which may also be welded to the suspension hook. It is an advantage of the invention that the wall portions of the ceiling and bottom are welded together to form a rigid rectangular frame. The invention further achieves the advantage that the channel is composed of two simple pre-fabricated parts in the form of flat plates, facilitating production, storage, and assembly. To facilitate assembly, increase safety at work and improve the stability of the channel, the joints of the wall panels and floor and ceiling panels are mutually shifted. Therefore, according to the invention, a very efficient and economical construction of energy channels with satisfactory static strength and resistance to earth pressures and random loads, such as truck travel, can be implemented. The use of panels with ceramic hollow inserts achieves material weight savings of approximately 25%, and investment savings are achieved against reinforced concrete pre-fabrics. The production of low-profile panels is very advantageous for ceramic pastry manufacturers.

Claims (5)

1. A passage mounted channel, in particular for energy purposes, of prefabricated plates, characterized in that its wall parts (1) and ceiling and bottom parts (2) are assembled by mutually displacing the contact surfaces and their outer reinforcement is welded to each other by support lines to form rigid stiffeners. 2. The throughfeed channel according to item 1, characterized by! in that its prefabricated plates, i.e. the wall parts (1) and the machine and bottom parts (2) are made of ceramic hollow inserts (4j and reinforced concrete). 3. The through-passage channel according to point 2 of the ceiling, which is also welded to the walls. After carrying out all the supporting welds, these are protected against corrosion by plaster mortar plastering. The assembled energy channel of the outer and inner surfaces is smooth and free of protrusions, making it easier to carry out the waterproofing with a protective coating and to fill it with either a completely or to the required height, the ceiling, possibly also the vicinity of the channel, with additional layers forming the structure of the vehicle. Non-plotted pins can be inserted into the vertical contact joints, to which vertical U-shaped rods with cable-jibs, consoles or other support structures are welded to the technology channel. The described energy duct according to the invention forms a statically strong unit which resists all the external loads of the earth and the random effects caused by the operation of the duct. It can also be used for other non-energy purposes, for example for the construction of bucolector and south engineering networks. The invention also permits the execution of various bottom, wall and ceiling openings for drainage, cable or pipe outlets, and steel inlets for inlet openings. The energy channel according to the invention can also be made of reinforced concrete elements without ceramic inserts. This alternative is suitable for utilizing the spare capacity of the manufacturer of reinforced concrete prefabricated elements, or as a prefabricated element. 1, characterized in that the outer reinforcement (5) of the ceiling and bottom parts (2) protruding from the semi-grooves at their edges reaches the maximum overall thickness of the ceiling part (2). 3 4 205359 nelů. An example of a pass-through duct for energy and other purposes according to the invention is shown in the accompanying drawings, in which: Fig. 1 shows a transverse vertical cross-section of a set channel, Fig. 2 is a cross-sectional view of a ceramic hollow insert and reinforced concrete; Fig. 4 is a view of the wall section; and Fig. 5 is an oblique plan view of the open channel assembly. The base and insulating layer 3 is provided with a bottom portion 2 with a protruding outer reinforcement facing upwardly from the half-groove edges whose width is equal to the thickness of the portions 1. The protruding outer reinforcement does not exceed a total thickness of the portion 2d. On the stepwise lowered portions of the walls 2, the wall elements 1 are positioned such that their contact surfaces are supported on the lowered surfaces of the rebates at the edges of the bottom parts 2 and provided with recessed steel plates 6 and welded with the main reinforcement to the wall part 1 and the hooks 7 welded on the main reinforcement of the wall section 1. From above, the channel is covered by the ceiling part 2 projecting the outer reinforcement with the facing downward. The individual parts are arranged such that a pair of ceiling parts 2 is placed in the same displacement of the contact joints as a pair of wall sections 1. All spring reinforcements contacting parts 1, 2 are welded together. In the excavation, 2 bottom parts are placed on the base insulation layer 2, and the wall parts 1 are placed on them and welded to them. 4. The through-mounted duct according to claim 1, characterized in that the external reinforcement is welded to one another by means of steel plates (6) embedded in the wall sections (1), the steel plates (6) being guided to the main reinforcement to which it is also when the hanging hook (7) is cooked. 5 drawings
