    FIRE-PROTECTED BUILDING ENCLOSURE Field of application The application generally concerns a fire-protected building services enclosure. Background In industry and building services, the possibility of fire caused by electric cables has increased significantly, with the increase in the use of electrical equipment and electrical systems. Typically, the cables pass through buildings, floors and rooms, with the cables forming a connection throughout the building.
    - In buildings and other buildings, cables are typically coated with plastic, which releases toxic flue gases into their environment in the event of a fire. Pipes containing plastic or other combustible material also emit toxic gases.
    Em. To solve the problems, fire-protected building technology enclosures have been developed in which the cables and pipes are protected by a separate, fire-insulating fire-protected space in which the cables can be installed. In them, fire protection is implemented in such a way that the temperature rise inside the housing is limited to 180 ° C during a fire for a certain period of time.
    One known solution is a fire-protected housing according to the utility model FI11972, which, however, has the problem of its high manufacturing costs, which increase the selling price of the housing. The large size of the enclosures also limits their use in confined spaces, such as stairwells.
    2 SUMMARY It is an object of the invention to solve the problems of the prior art and to provide an inexpensive, modular and compliant fire-retardant housing which is possible to install prior art solutions.

A first edge portion 124a and a second edge portion © 30 124b are formed in the flat portion 123 along the entire length L of the cover & 102 (housing 100) by bending, or securing them to each other. The edge portions 124a, 124b 3 may be substantially perpendicular to the plane portion 123 as shown, or the angle between the O plane portion 123 and the edge portion 128a, 128b may be less than 90 °, with the cover 102 securing more tightly 102 to the base 101, or more than 90 °, which facilitates the installation of the cover 102 on the base 101.
    The base 101 and the lid 102 are made of a steel plate, which may include an electric or hot-dip galvanized coating. The material thickness of the steel plate is e.g. 0.5-2 mm. In addition, the base 101 and the lid 102 may be powder or wet painted.
    - The insulators 105a, 105b, 105c, 105d are arranged inside the housing 100 so as to form a substantially integral insulation (insulating layer) to protect (surround) the fire protection space 150, thereby forming a fire-insulated space when the cover 102 is attached to the base 101. Insulators 105a, 105b, 105c, 105d abut each other with the cover 102 attached to the base 101 so that the insulation of the fire protection space 150 becomes substantially uniform and there is no around the fire protection space 150 towards the non-insulating the working planes 129a, 129b come between the insulators 105c, 105d and the insulator 105b. The base 101 and the lid 102, which when fastened together form the housing-like structure and the outer shell (surface) 152 of the housing 100, are in turn arranged to protect (surround) the insulators 105a, 105b, 105c, 105d.
    The material of the insulators 105a, 105b, 105c, 105d is, for example, gypsum board, wool, magnesite board, fire protection board or other material that prevents heat transfer. Unlike the images, they may be formed of several layers and - comprise several materials, e.g. a combination of wool and gypsum board. In addition, the insulators 105a, 105b, 105c, 105d may be shaped or grooved so as to more effectively prevent heat transfer. They are attached to the base 101 and the cover 102, e.g. with glue or mechanical connectors (clips).
    The thickness of the insulators 105a, 105b, 105c, 105d is typically 13-25 mm, e.g. N 25 13.15, 18, 21 or 25 mm.
    The housing 100 may further comprise at least one fastening means 108 for fastening the cover 102 to the base 101 with insulators 105a, 105b, 105c, 105d to form an insulated fire protection space 150. Each of the fastening means 108 is mounted as shown through the flat portion 123 of the cover 102 to the fastening planes 129a,> 30 to 129b. The outer surface 152 of the base 102, along its entire length L, is further formed of at least one corner portion 128a, 128b, e.g. , 128b from the bending point at the top, a (outgoing) recess (depression) 128g, 128h extending towards the planar portion 127, which at the fold 128e, 128f falls non-existent before the angle between the edge portion 128a, 128b and the planar portion 127, i.e. the edge portion 128a, 128 bending or joining points at the bottom.

It may be formed of one or more parts, e.g. one, two, three or more parts, and may comprise openings through which the base 101 can be fastened to the mounting base by fastening means 108. At least one edge portion 124a, 124b of the cover 102, e.g. 125b. The reinforcing fold 125a, 125b is formed by bending the end 180 * of the edge portion 124a, 124b at an angle to the inner surface 159. The purpose of the reinforcing fold 125a, 125b is to stiffen the edge portions 124a, 124b and round their ends. Alternatively, or as shown in the figures, in addition, a heat-expandable seal ( sealing tape) 131, which is intended to prevent heat transfer inside the housing 100 as it is pressed against the bottom edge portions 128a, 128b. Alternatively, the seal 131 may be formed in the insulator 105b of the cover 102 to be pressed against the mounting planes 129a, 129b of the base 101, or to the mounting levels 129a, 129b of the base 101, whereby it is pressed against the insulation 105b by heat.
    O O 25 - If the recess 128g, 128h of the base 101 is formed only in the second O edge portion 128a, 128b, then a reinforcement fold 125a, 1250 and / or a seal 131 is formed in the corresponding edge portion 124a, 124b of the cover 101. If the recess> 128g, 128h is formed in both edge portions 128a, 128b, then the reinforcement fold & 125a, 1250 and / or the seal 131 are formed in the same way in both edge portions 2 30-124a, 124b g N its planar portion 123 such that said insulator 105b abuts the inner surface 159 of the planar portion 123, leaving at least the lower portions of the lower portions 124a, 124b of the lower portion 102 free of the entire length L of the lid 102.
    to the plane portion 123, e.g. with glue or a press fit, between the edge portions 124a, 124b. An air gap may be left between the insulator 105b and the flat portion 123 if the insulator 105b has grooves or notches, or due to the attachment by the fastening means 108 of the cover 102. The adhesive used for fastening may also leave a gap of 0.1-3 mm between the insulator 105b and the planar portion 123. When the cover 102 is mounted by pressing onto the base 101, each recess 128g, 128h of the edge portion 128a, 128b of the base 101 receives the edge portion 124a, 124b of the corresponding cover 102 so that the edge portions 124a, 124b, 128a, 128b of the cover and the base 101, 102 are substantially the same. in the plane along the entire length L of the housing 100 with the cover 102 attached to the base 101. If a reinforcement fold 125a, 1250, a seal 131 or both are formed in the edge portion 124a, 124b, they abut the edge portion 128a, 128b of the base 101 recess 1289, 128h L. When the base 101 is mounted e.g. space (gap). Figs. 2a-2b show examples of the above figures for a purpose-built combination housing (building technology housing) 100 made of corresponding materials and structural solutions, with at least one pipe and / or or non - flame retardant installation space for shielding a halogen - free cable 258.
    O O 25 - The bottom 101 of the combination housing 100 may be formed as shown in the previous figures, with each edge portion 128a, 228b being formed by a fold 128e, 128f, a recess 128g, 128h and a> mounting plane 129a, 129b facing the fire protection space 150. Alternatively, in contrast to the previous figures, the second edge portion 228b may be formed as shown without the recess 128h, with only the first edge portion 128a having a recess 128g. An edge portion 228b is formed in the planar portion 127 of Figs. thence. The edge portion 228b is formed
    bent like a side portion 128a by bending the mounting plane 129b facing the fire protection space 150 for mounting by the fixing means 108 of the cover 102. The installation of the insulators 105a, 105c, 105d of the base 101 differs from the examples of the previous figures only in that if the edge portion 228b does not have a recess 128h, the insulator 105c completely abuts the inner surface 154 of the edge portion 228b, leaving no empty space between it and the insulator 105c
    156. The combination housing 100 may further comprise a cable support plate 106, such as the examples of the previous figures, which is attached to the insulation as described above. The composite housing 100 further comprises a pipe base (part) 240 in which a flat part 241 is formed, which is typically mounted against the same mounting base as the flat part 127. The entire length of the pipe base 240 (combination housing 100) L is formed in the flat part 241. a first flange portion (stiffener portion, flange) 242 for supporting and stiffening the attachment of the pipe base 240 to the outer surface 152 of the base 101, i.e., its flange portion 228b, and a second flange portion 244. conversely, if the bases 101, 240 are mounted on the mounting base separately. At least one attachment point (not shown) for attaching pipes or cables is formed on the inner surface 262 of the plane portion 241. The edge portions 242, 244 are formed by bending, or attaching, to the planar portion 241. The edge portions 242, 244 may be substantially perpendicular to the planar portion 241, as shown, or the angle between them may deviate therefrom. o Irrespective of the angle, the edge part 242 must be formed so that the outer surface 260 of the pipe base <25 240, and at the same time the edge part 242, can be placed (fitted) O for fastening against the outer surface 152 of the edge part 228b of the base 101. essentially at the same level. The pipe base 240 can be fastened to the base 101 through the edge portion 242 by fastening means 108, e.g.
    ON A third fixing plane (bending) 245 is formed in the edge portion 244, unlike the edge portion 242, by bending the mounting space 258 and the fire protection space 150 in the manner of the edge portion 228b to secure the cover 202 by fixing means 108 to the detached, or fastened, base 101 and tubular

The inner surface 159 of the lower part 124a, the entire length L of the cover 102, is formed by bending a reinforcing fold 125a stiffening the round part 124a and rounding its end. Alternatively or in addition, as shown in the previous figures, a heat-expanding, heat-expanding seal 131 may be formed on the inner surface 159 of the edge portion 124a along its entire length L. differs from the previous figures in that it is not formed by bending the reinforcing fold 125b but a mounting plane 246 facing the mounting space 258 and the fire protection space 150 to abut (support) the mounting plane 245 of the flange 244 of the pipe base 240 and allow the cover 202 attachment to the base 101 and pipe base 240. The attachment plane 246 may be substantially parallel to the plane portion 123 or the attachment plane 245, as shown in the figures, but alternatively it may also be at some angle to at least one other. against the inside of the plane portion 123 159 so as to leave at least the lower edge portion 124a of the inner surface 159 free along its entire length L and the entire edge portion 224b N 25 - the inner surface 159 free. As shown, the width D of the insulator 105b is greater than the width of the base 101, extending partially toward the mounting space 258, while leaving a portion of the inner surface 159 of the planar portion 123 free. Alternatively, in contrast to the figures, the insulator 105b may extend substantially flush with the outer surface 155 of the insulator 105d = E so that the insulation thickness of the fire protection space 150 is not thinned, or the insulator 105b may extend to the edge portion 224b. Irrespective of the width S D of the insulator 105b, it is fixed, as in the example of the previous figures, e.g. with glue or N compression fittings between the edge parts 124a, 224b.
    The cover 202 is intended to abut the base 101 and the pipe base 101, 240 so that its insulation 105b abuts the mounting planes 129a, 129b and its mounting plane 246 against the mounting plane 245, the insulators 105a, 105b, 105c, 105d delimiting the fire protection space 150 as in the previous figures. and the inner surfaces 159 of the flat portion 123 and the flange portion 244, the inner surfaces 262 of the planar and flange portions 241, 242, 244 of the pipe base 240, the outer surface 152 of the flange portion 228b and the insulator 105b define the mounting space 258. 129a, 129b, 245, 246 with attachable attachment means 108.
    The pipe base 240, like the base 101 and the cover 202, is made of an electrically or hot-zinc coated steel plate, e.g. 0.5-2 mm thick, and can also be powder or wet painted. Alternatively, in contrast to the examples in the figures, the cover and base structures 101, 202, 240 of the combination housing 100 may be implemented such that the planar portions 127, 241 are a unitary planar portion formed by bending, or securing, the edge portions 128a, 244, and securing a flange portion 228b, 242 mechanically integrated into a single integral panel portion 127, 241.
