  • the supporting structure 2 is designed to secure a U-shaped junction of walls or other building structures in the opening and is technologically performed in the same way as frame 1. Thus, the supporting structure 2 can follow the shape of the opening either completely or partially.
  • the frame 1 has the shape of a U-shaped opening into which it is installed, and the supports 15 and 16 may have a shape that partially coincides with the shape of the U-shaped opening.
  • the proposed design can ensure installation of the frame in a U-shaped opening of any shape.
  • the supports 15 and 16 are hingedly connected to the frame 1 by the free ends of their sides, as shown in Fig. 17.
  • the hinge connection 3 can be made in the form of a male element (for example, a rod) and a female element (for example, a sleeve). Gaskets, lubricants, balls, or other means that facilitate the rotation of frame 1 can be placed inside the sleeve.
  • Male and female elements can be attached both to frame 1 and to supports 15 and 16.
  • the thickness of the contours 13 and 14 of the frame 1 should preferably not exceed the thickness of the supports of the supporting structure 2.
  • the planes of the frame 1 will not extend beyond the planes formed by the supporting structure 2 and the dimensions of the frame in terms of thickness will be determined the size of the supports 15, 16 or in other words the width of the profile from which the sides of the supporting structure 2 are made, as shown in Figs. 18, 19 and 21.
  • the thickness of the contours of the frame 1 should not exceed half the size of the supports 15, 16.
  • the supporting structure 2 contains through holes 5 in a closed steel profile for fastening elements, and the diameter of the holes in the side of the profile facing the frame is larger than the diameter of the holes on the opposite side of the profile. This allows the heads of fasteners, such as screws, to be placed inside the profile. If the thickness of frame 1 does not exceed half the thickness of the supporting frame 2, this will allow the holes 5 to be positioned so that they are accessible even when frame 1 is closed
  • the frame may contain a frame rotation limiter 17 (lock), which does not allow the frame 1 to be rotated inside the opening.
  • the rotation limiter for example, a magnetic lock
  • the rotation limiter can be installed on special protrusions 7, mounted on supports 15, 16 and facing the frame 1, as shown in Fig. 19. If, when closing the hatch door, have a natural stop in the form of part of a wall or opening, then the presence of a limiter is not necessary.
  • Frame 1 may contain flat steel elements 8, attached perpendicular to the edges of the closed steel profile, forming the inner perimeter of the contour. Such flat elements, together with the edges of the profile, form a recess into which the substrate 9 for the facing material can be installed (shown by the dotted line in Figs. 18 and 20).
  • One of the sides of the corner profile can be used as flat elements 8, while the second side of the corner profile is welded to the corresponding face of the profile from which the frame 1 is made.
  • Holes 10 can be made in the flat elements 8 to secure the substrate 9.
  • the substrate can be attached to the frame in any suitable way.
  • the frame of the technological hatch according to the third option works as follows.
  • the frame is made based on the size and shape of the U-shaped opening. To do this, select the appropriate dimensions and shape of the supports 15 and 16, as well as the contours 13 and 14 of the frame. If necessary, the length of the side sides 15 and 16 of the supports and the corresponding dimensions of the frame contours 14 can be different, depending on the shape of the opening, i.e.
  • the U-shape may be asymmetrical.
  • the supports 15, 16 of the supporting structure 2 are fixed by means of fasteners in the opening of a wall, shaft, floor, ceiling or other element of the building, as shown in Figs. 24 and 25. Due to the larger diameter of the holes 5 for fasteners along the inner perimeter of the head of the fasteners there will be located inside the metal profile.
  • a substrate 9 is installed by means of fastening means (for example, screws) (shown conventionally with dashed lines in Figs. 17, 18, 20 and 23). Drywall, asbestos-cement or plastic board, plywood or other suitable sheet material on which the cladding 11 is fixed (for example, ceramic tiles, plaster, panel). In some cases, the facing material can be attached directly to the profiles of the frame 1.
  • the substrate 9 can be attached to the frame 1 before installing the frame in the opening.
  • the substrate 9 and/or facing material installed on the frame 1 forms a technological hatch door, a fragment of which is shown in Fig. 24.
  • the facing material 11 attached to the frame must match the shape of the opening being closed, for an aesthetic or complete final appearance.
  • the width of the facing material 11 exceeds the width of the hatch frame and corresponds to the width of the opening, which will completely make the inspection opening invisible in the closed position of the hatch door.
  • the door opening angle also depends on the location of the hinge 3
  • Fig. 24 shows fragments of the two extreme positions of the hatch door.
  • bevels 4 allows you to open the hatch door with the facing material installed on it at an angle of more than 90 degrees.
  • a bevel of at least 25 degrees must be made on its inner side.
  • a handle (not shown) can be attached to the door.
  • the user can gain access to the hidden cavities by turning the door, including frame 1, open position.
  • the absence of movable or retractable levers in the design eliminates sagging of the hatch door, which ensures a minimum gap between the facing material 11 and 12, and also allows this technological hatch to be made of any size without compromising its performance qualities and characteristics.
  • the absence of sagging, regardless of size and weight, ensures that in the closed position of the hatch door there is a minimum gap between the facing materials 11 and 12 without the use of movable levers in the frame structure when it is possible to open the hatch door at an angle of more than 90 degrees.
  • bevels 4 provides in this design the ability to open the hatch door at an angle of more than 90 degrees, without using a system of movable levers, which can lead to sagging of the hatch door.
  • all frame options have common technical features regarding the fact that in the closed position the projection of the frame 1 repeats the projection of the supporting structure 2 (as shown in Fig. 5, 13 and 21).
  • Another common technical feature is the presence of bevels 4 at the end sections of the supporting structure in the area where the hinge joint 3 is located.

Abstract

L'invention se rapporte à des trappes techniques que l'on installe dans des embrasures de murs, de plafonds ou de sols de forme angulaire, notamment des trappes de contrôle et d'accès pour donner accès à divers espaces vides cachés, des bâtiments, des communications et des appareils. Cette carcasse de trappe technique comprend un cadre (1) et une structure porteuse (2). Le cadre (1) se présente au moins sous forme d'un contour plan à quatre côtés. La structure porteuse (2) se présente sous forme de supports faits de profilé d'acier clos. L'extrémité d'un des côtés de chaque support est connectée par charnière au cadre (1) de sorte qu'en position fermée, la projection du cadre (1) reprend la projection de la structure porteuse (2). Les sections d'extrémité des supports de la structure porteuse (2) dans la zone de disposition de ladite connexion par charnière comprennent des biseaux disposés à l'opposé de la direction d'ouverture dudit cadre. Il est ainsi possible d'augmenter la solidité de la carcasse de la trappe technique.
