The following will be on FIG. 1 Reference is made, which shows a vertical sectional view through an object guard. The object guard after FIG. 1 is surrounded by a frame 1 which is inserted into a building opening, wherein in the illustrated embodiment the Outside with 2 and the inside of the building facing side is denoted by 3. The safety screen has a plurality of fins 5, 6, 7, 8, 9, 10, 11, 12, which are each arranged to extend in the horizontal direction. In principle, the lamellae can also be arranged in the vertical plane instead of in the horizontal plane. In the illustrated embodiment, the fins 5 to 12 are at least partially secured to tubes 20 which are secured relative to the frame 1. In the case of the vertical arrangement of the individual slats, the tubes 20 extend in the horizontal direction.

The slats 5 to 12 are preferably bent or angled, as is apparent FIG. 1 it can be seen, wherein the lamellae have a first portion, the z. B. is designated 6a and facing the outside, while a second section, z. B. designated 6b, is provided extending to the building interior. Each blade 5, 6, etc. is provided with in this embodiment with each other in the vertical direction aligned bores 14, 14 ', etc., each receiving one of the tubes 20. Thus, the lamellae 5 to 12 are fixed relative to the tubes 20 and secured thereto, ie the lamellae 5 to 12 are inserted over the tubes 20, wherein in each case a tube 20 vertically aligned and aligned holes 14, 14 ', etc. of individual lamellae ,

In the FIG. 1 According to the embodiment shown, the uppermost lamella 12 can consist only of the inward-facing section 12b and is fastened in a suitable manner with respect to the respective tube and / or the frame 1. The frame 1 consists of the building opening of an upper and a lower frame portion and these interconnecting lateral sections.

At the in FIG. 1 shown embodiment, at least partially anchor 15, preferably tie rods, are arranged in the tubes 20. As far as the anchor 15 are formed by tie rods, the biasing force is applied via screw 17, 18 or hydraulically via the respective tube.

The anchors 15 are arranged in the interior of a respective tube 20, which preferably acts as a pressure tube, as a result of which the pressure pipes are biased by the armature. Such tubes 20 are able to transmit high debris loads, ie to significantly increase the stability of the protective screen.

In a preferred embodiment, the interior of the tubes 20, in which optionally an anchor or tie rod is arranged, filled with ceramic material, whereby the stability of the tubes is further increased.

In a further embodiment of the protective screen, hollow profiles are formed on the side facing outward, which in FIG. 1 are indicated at 22, through which either a heating band or a liquid heating means can be performed. These hollow sections 22 are adapted to the lamella shape and are preferably prepared as a complete register frame, which is placed in front of the actual lamellae and screwed there preferably by means of screws to the frame 1. The hollow sections 22 are used to heat the steel blades and prevent freezing at temperatures around and below freezing. Alternatively, the hollow profiles 22 may also be otherwise connected fixedly to the respective end faces of the laminar sections 5a, 6a, etc.

The mounting frame 1 is preferably welded to a steel, pressed frame with angular profile, which is formed outside the frame 1 in the building opening and not shown in the figures.

How out FIG. 1 Further, the lamellae portions 6a and so on are formed obliquely upward from outside to inside, the lamella portions 6b, 7b, etc., starting from the tubes 20, extend obliquely downward toward the inside. The lamellae 5, 6 prevent this bent or angled shape direct penetration through the grid produced by them.

In the area of the lamellae 5 to 12 pointing to the building interior, in a preferred embodiment, pressure-impulse elements are provided which fill the space between adjacent lamellae, and z. B. at a high pressure wave (blast wave) close the blade gap, so that the pressure wave can not penetrate into the building interior.

As FIG. 2 shows, the tubes 20 are provided at predetermined intervals along the building opening to stably hold the individual slats 5 to 12 in the building opening and order to prevent external influences on the interior of the building. The distances of the individual tubes 20, 20a, 20b, 20c are selected depending on the given stability requirements.

In FIG. 2 are shown in series with each other two pressure shock elements, while in FIG. 1 in each case only one in the respective space between fins located pressure shock element 26 to 32 can be seen. The pressure impact elements 33, 34 are attached laterally to the frame at the sections designated 1a and 1b and secured between the side wall sections 1a, 1b by support walls 35.

FIG. 3 shows a front view of the object protection grid, ie seen from the outside 2 and illustrates that at least one tube 20 is provided with a tie rod 15, while the laterally adjacent thereto tubes 20a, 20b, 20c, 20d need not have a tie rod. The slats are in FIG. 3 only partially designated for reasons of clarity. According to the present invention, the tubes 20 are biased by a tie rod 15 with respect to the peripheral frame, in particular to ensure a correspondingly high static and dynamic resistance force upon impact of debris loads, for example due to an aircraft crash. Such a pretensioned object guard then acts like a net from which the debris is collected, this grid is significantly defined by the prestressed tie rods, while the slats play only a minor role. For the normal air intake, the installation of the tie rods for pretensioning the front safety screen half is not significant, even with the impact of Blastwellen produced by the tie rods bias does not matter. However, the object protection grid according to the invention is to be designed so that it has the required static and dynamic resistance even when hitting debris loads. For this purpose, preferably all pipes 20, 20a, 20b, etc. are prestressed by tie rods.

FIG. 4 shows a partial view of a fin gap with a pressure shock element. This pressure shock element has the function of a pressure flap. The pressure flap consists of a housing 40 which between adjacent slats, z. B. 7, 8, is fixed. The housing 40 has mutually opposite openings 41, 42, between which a preferably spring-mounted closure device 43 is arranged or oscillating. Spring means 44, 45 hold the closure means 43, for example in the form of a cylindrical valve body, in a rest position in which air passes through the openings 41, 42 can pass through. In the case of a pressure wave, for example in FIG. 4 coming from the left, the valve body 43 is in FIG. 4 shifted to the right and then closes the opening 41, so that the pressure wave can not propagate to the right inside the building. The openings 41, 42 extend in the direction of the channel defined by adjacent lamellae according to the arrow 55 (FIG. Fig. 1 ).

The preferably cylindrical valve body 43 is supported in this embodiment by a pendulum rod 46 relative to the housing 40, wherein the pendulum rod 46 with one end 46 a, the valve body 43 carries and with another end 46 b oscillating relative to the housing 40 is mounted.

Above and below the openings 41, 42, the housing is provided with sealing edges 48, 49, so that z. B. at a blast wave in FIG. 4 Coming from the left, the valve body 43 is displaced to the right in the direction of the opening 41 and on the sealing edges 48, 49, which leads to the closure of the opening 41. After pressure drop, the valve body 43 is due to the spring means 44, 45 again shifted back into its central position or starting position, so that an air flow through the openings 41, 42 is made possible through for the purpose of cooling of safety components. Preferably, such pressure impact elements are used as pressure surge elements, as used in conjunction with the DE 10 2008 040 462 are described in detail.

The object protection grid described above allows a flow of cooling air, in particular in FIG. 1 and FIG. 4 viewed from right to left, but at the same time ensures a protection against incoming from the outside 2 Blastdruckwerten (Blastwellen) to protect the building side located components in which the pressure shock elements located between the slats 5 to 12 are closed. The safety screen is an outer shell to safety components, such as cooling systems or emergency diesel engines, which require large amounts of air from the outside for their operation and their cooling. Such safety screens have a minimum size generally of 1 x 1 m ² . For large-area openings individual segment groups of such safety screens are used, which are assembled together by steel links to large-scale elements, as a result, no restrictions on the dimensions of Object protection grid exist. the safety components such as cooling systems or emergency diesel engines are located on the Fig. 1 right side of the object protection grid.

Object guard grids of the type according to the invention are preferably installed in openings in concrete walls, in which surrounding steel mounting frame are inserted or they are used in steel skeleton structures, wherein the individual guard grille elements are welded directly to the steel beams. For receiving the individual tubes 20 with or without tie rods 15, the individual slats 5 to 12 are provided with holes 14, 14 ', etc., through which the tubes or tube profiles 20 are performed. The tubes 20 are also performed by trained in the frame 1 holes 50, 51, as in detail FIG. 1 is apparent.
