Embodiment Construction

[0024] Figure 1A and 1B A hatch 3 is schematically shown secured to an opening made in a wall 2 constructed of refractory material using the frame structure 1 of the invention.

[0025] Such hatch-equipped openings are required in particular in walls of cabin structures of ships for inspection measures and / or renovation operations. While it is desirable that such openings and hatches are always pre-designed and completed in the cabin structure prior to installing the prefabricated cabin on board, the subsequent addition of such openings is also necessary for various reasons.

[0026] Figure 2A and 2B Schematically shows the frame structure 1 used in the present invention Figure 1A the embodiment. In this embodiment, the frame structure 1 consists of four individual frame elements 4 which are straight in their longitudinal direction and are connected to each other by means of joints at the ends of the frame elements for Provide overall frame structure. The individual fr...

Abstract

The invention relates to a method and a frame structure for constructing a frame for a wall opening equipped with a hatch. In particular, a method and frame structure for an opening provided with a hatch (3) and made in a wall (2) constructed of refractory material, said method comprising bending a One or more frame elements (4) that extend along the straight section of the edge of the opening in a straight condition assemble the frame, and the one or more frame elements (4) bent from metal material include a The edge portion (5) of the first section on which the surface of the wall (2) rests, and the folded portion (7) connected to the edge portion in a bendable manner at least along the straightly extending section of the frame element, and the folded portion (7) Having a first section resting against the opposite surface of the wall, after placing the frame element in the wall opening, the folded portion is bent in such a way that the second section between the folded portion and the edge portion At least one set of clamping holes made in the segment becomes located close enough to each other to insert a clamping screw (8) through these holes, said clamping screw serving as said second The means for the segments to approach each other, which causes the folded portion and the first segment of the rim portion to press against opposing surfaces of the wall to secure the frame stably to the wall opening.

Description

technical field [0001] The invention relates to the construction of a frame for a hatch designed for an opening made in a wall structure of refractory material, and to this frame structure. Background technique [0002] Wall structures of refractory materials are often used in locations where the consequences of a fire are more devastating than usual, such as, for example, in ships or other offshore structures. Usually, this refractory wall structure at these sites consists of metal plates making up the surface of the wall structure, and a honeycomb assembly fitted therebetween, usually formed of metal plates by bending. A separate thermal insulation material can further be used within the wall structure. [0003] In these applications, the structure is also usually implemented as a reasonably compact unit to save space. Therefore, the refractory wall structures used generally require various maintenance openings equipped with hatches in view of the various maintenance pro...
