LOCKING ELEMENT FOR ANCHORAGE OF A U- SHAPED CEILING SECTION TO A U-SHAPED WALL SECTION PERPENDICULAR TO IT This invention relates to a locking element for anchorage of a U-shaped ceiling section to a U-shaped wall section perpendicular to it, both constituting clamping sections for joining together ceiling and wall elements in a machine-room for fans, for example, and comprising an improvement of the jointing device described in the Swedish laid-out Patent Specification No. 312 217, for fireproof and pressuretight elements for the construction, for example, of machine-rooms for fans.
The building elements, in the form of sheets, are placed at the time of assembly with their longitudinal sides facing one another and are used both for walls and ceilings of the machine-room. The elements are joined together by means of special, U-shaped clamping sections which are anchored to one another at the top end, at the bottom, to special floor sections, so forming the load-carrying skeleton in the walls and ceiling of the machine-room. The ceiling sections, however, differ in shape from the wall sections, which prevents the manufacture of both in a single section rolling mills as would be desirable. Furthermore, in the floor sections there must be special cut-outs into which the wall sections must fit. These cut-outs require special cutting tools and are therefore fairly expensive. A reduction of the cost of manufacture and stockkeeping of ceiling, wall and floor sections could now be attained if the ceiling and wall sections were alike and if the cutouts in the floor sections could be eliminated.
According to the invention these desires are met through the fact that, at the time of assembly, the sections are anchored to one another by means of a locking element which is inserted in the two meeting sections and is so formed that it can be used both for 'ceiling and floor.
The invention will now be described with reference to the attached drawings, of which FIG. 1 shows a section of a joint between two ceiling or wall elements,
FIG. 2 shows the new locking element in various prespectives, of which FIG. 2a is a lateral view,
FIG. 2b is a view from above,
FIG. is a view from the right, and
FIG. 2d is a view from the left,
FIG. 3 shows an exploded view of an anchorage by means of the locking element of a ceiling section to a wall section and of a wall section to a floor section, and
FIG. 4 shows the locking element at an intermediate stage in the production process.
FIG. 1 shows at 1' two wall elements consisting of rectangular sheet metal covers and enclosing a heatand sound-insulating material. The sheet metal covers terminate in U-shaped slots 2 against the bottom of which the clamping sections 3', 3" are held pressed by a number of T-shaped bolts 4' with nuts 7 placed at regular intervals along the sections. The wall elements joined together in this way form walls and ceiling in the machine-room. The sections 3" on the inside of the walls and ceiling meet at the top and are locked to one another by locking elements in accordance with FIG. 2; the same locking elements are used also where the wall sections meet the floor section.
The way in which locking is effected with the aid of the locking element in FIG. 2 is shown in detail in FIG. 3, where 1 shows an internal ceiling section, 2 an internal wall section and 3 a floor section. The locking element in FIG. 2 is shown in two positions, between ceiling and wall section 2 and between wall and floor section. In assembled condition the locking element is inserted in the respective sections, but for the sake of clarity is shown drawn out from them.
The locking element consists in principle of two cutoff U-sections perpendicular to one another, one with web 4 and shanks 5 in FIG. 2c and 3, the other with web 6 and shanks 7 in FIG. 2b and 3, held together by apshaped intermediate part 8 in FIG. 2a, 2b, 2c and 3. The sections fit into the ceiling and wall sections 1 and 2 with a certain clearance necessary for simplification of assembly. In the web they have bent-out lugs 9 and 10 in FIG. 2a, 2b and 3, which, when inserted into the respective ceiling, wall and floor sections, snap into corresponding holes 11, 12 and 13 in the latter, whereby said sections are extremely simply locked to one another.
For the locking effect between ceiling and wall sections and the locking element, use is made of the shape of shanks 5 in FIG. 1, the free ends 6 of which are bent through and hold the locking element in FIG. 3 in position for engagement of the lug 9 (10) in the hole 11 (12). Lug and hole are so placed that, with sections and locking element in final position, the ceiling section 1 in FIG. 3 rests with its end surface against the web 2a of the wall section 2. The latter section is prevented by the bent portion of the intermediate piece 8 in FIG. 2a and 3 from being pushed upwards so far that its end surface lies on the same plane as the surface of contact 14 (FIG. 3) of the shanks of ceiling section 1. Instead, the shanks 7 of the locking element are drawn up so far that their end surfaces 15 lie on the same plane as the surfaces 14. This is necessary in order that, like the surfaces 14, they shall provide a sealed abutment against the packing in the bottom of the U-shaped slot 2 in FIG. 1. A small remaining gap between shanks 5 and 7 in FIG. 3 is sealed after assembly with special sealing material.
For satisfactory locking effect between the locking element and the floor section the intermediate piece 8 (FIG. 2b) is formed with a plane portion at such a distance from the web 6 that the floor section, inserted in position, is held rigidly in position for engagement of the lug 10 in the hole 13 (FIG. 3).
As is seen, the wall and ceiling sections may be similarly shaped at the ends. Apart from cutting into the desired lengths, the only action necessary is drilling of holes 11 and 12 (FIG. 3) at equal distances from the ends. In the bottom section holes 13 alone are drilled instead of entire cut-outs for the wall section 2.
The locking element thus brings a considerable saving both in production and storage costs for the section.
The locking elements can also be used for mutual lateral steering of the external ceiling and wall sections. If the sections 1 and 2 in FIG. 3 are considered to be reversed, i.e., with the web in the opposite direction to that shown, it will be readily realized that the locking element can be inserted into the sections in the same way as described above, but with the difference that no locking effect arises. Nor is this desirable since the outer sections, which are held in position by bolts 4 in FIG. 1, must be mobile in the longitudinal direction of the bolts and must not be prevented from pressing against the building elements 1 when the nuts 7 in FIG. 1 are tightened.
The locking element is made of plane sheet metal by cutting and successive bending in several operations into the final form shown in FIG. 2. At one stage of bending the element has the form shown in FIG. 4.
The locking element in FIG. 4 can be used with advantage for direct anchorage of struts and the like with a section as shown by in FIG. 1 to plane plate or concrete surfaces. For this purpose the section 1", 2" is inserted, as described above, into the strut and is locked with the lug 3' in a corresponding hole in the strut. The plane portion 4" is attached by suitable known means to the plate or concrete surface.
