Abstract

The present invention relates to a method and a profile element to obtain an outer ending at a deck form for concreting. The invention is characterized in that a loose profile element (1) with a profile enforced upper portion (2) and a web portion is placed overlapping an underlaying element or a wall (A) with the upper portion (2) on a correct level for the actual moulding hight, whereafter the web portion is attached in the underlaying element or wall (A).

Description

A method of obtaining an outer ending at a floor deck form for concreting and a profile element to perform said method
The present invention relates to a method to obtain an outer ending at a deck form for concreting and a profile element to perform said method.
When concreting a floor deck/a vault an outer ending towards an outer wall to be built must be constructed. There are several methods to obtain this. One method is to manually construct the ending in situ. Then you have to take the thickness of the floor deck form in consideration, as well as an outer wall with or without insulation and maybe an underlaying curtain wall. It is important that the outer side of the moulded new floor deck form is adapted to the underlaying wall/element.
Mostly used is a flat floor deck structure in the form of prefabricated 40 mm thick concrete slabs with partly embedded reinforcement. The flat floor deck structure will constitute a stationary mould for the finished floor deck having an underside of smooth concrete ready for painting. On the upper side of the flat floor structure concrete is moulded on the workning place, normally to a thichness of 20 to 24 cm.
A complete, supporting building framework has normally inner concrete walls and supporting steel struts.
To be able to mount and mould said construction it is also nescessary to make an ending or a mould cut off along the edge of the floor structure. In an often used solution today the manufacturer of the flat floor structure will mould an angle plate or iron into the moulding end of the floor structure which will form the mould cut off. This is an unflexible solution as the angle plate has to be made in different hights, as the measures and hights can vary for different buildings. The major problem of this solution is that it is very difficult to mount a big and heavy flat floor deck with such a precision that a mould cut off will be straight. Furthermore there is a risk that the angle plate will de deformed during transport and mounting. Thus the result can be a sloping and/or bent edge of the floor deck structure, which has to be corrected in the facade work to come, including extra costs.
The main object with the present invention is to obtain a mould cut off or a cut of which with few standard components can be adapted to both different thick floor structures and different degrees of insulations at the same time as a satisfactory sealing towards building components beneath can be assured. An other object with the invention is to obtain a standard element which in a correctly cut length can be mounted on most of the existing outer walls and curtain walls independently of board material and load carrying structure.
The objects stated above are obtained by giving the method and the profile element the characterizing clauses mentioned in the claims.
With the present invention the problem with a sloping and/or bent edge of the floor structure is avoided as the profile element together with telescopic braces will form this cut off and is mounted on the underlaying wall which always is straigt. The braces are simply adjusted to fit the actual hight gauge of the concrete floor structure. The profile element and braces form a restrained mould for the concrete moulding.
Because the profile element and the braces are mounted onto an underlaying wall, there is an other big advantage using the invention as the outer wall can be mounted in connection to the concrete mould cut off. This means that when the framework of the building is rising the house will be tight and indoor completing work can be introduced at an earlier stage and heating will be possible for a more rapid drying process, which dramatically will decrease the risk for damages caused by moisture and mould.
With a traditional solution the outer wall are mounted first when the whole framework is finished.
By using the invention it will be simple to cut off a profile element to an exact and correct length, or by using simple connectors to join shorter lengths to an element with the correct length.
Thus the profile element exists in a standard design undependent of the thickness of the floor deck frame. The manufacture takes place using section rolled and galanized metal sheet.
In the following the invention shall be more clearly described in connection to the enclosed drawings, where;
Fig. 1 is a diagrammatic view of a profile element according to the invention,
Fig. 2 is a side view with an insulation material on a curtain wall,
Fig. 3 discloses the necessary telescopic support to increase the ability to withstand a pressure from the moulding, Fig. 4 disclose a variant where the profile element is used withdrawn to make it possible to use a applyed outer insulation,
Fig. 5a discloses a variant of the profile element according to fig. 1, also dia- gramattically and with recesses to recieve bracket means,
Fig. 5b is a view from above showing the bracket means,
Fig. 5c is a side view of the bracket means,
Fig. 5d is a side view of the bracket means in its position in the profile element, and where
Fig. 6 is a sidview showing how the facade board has been mounted in connection to a withdrawn profile element by using a holed distance profile.
Fig. 1 shows a diagrammatic view of a profile element 1 with a U-shaped reinforcing flange 2. To make the mounting of the profile element 1 towards an underlaying element or a curtain wall easier a center drilled hole picture 4 is arranged as standard in the lower part of the element. A triangular emboss tp in several levels is also shown. The emboss is passing through on two of the sides and as an weakened folding notch at the lower horisontal side. This embosses tp makes it possible to simply press out a tongue element on the "correct" level to bear against the support in a mounted position for the intended moulding hight. At the applications where the tongue elements can be used they make a good support for a quick and correct mounting of the profile element 1. The tongue elements exist on several levels to make a correct adjustment to an actual moulding hight. The tongue elements can be numbered or have different colors, one for each level, which reduces the risk of a mischoice in folding out the tongue elements. When the profile element 1 exists in connection to an insulation board 3 the tongue elements do not have to be used as the hight of the insulating board 3 ensures a correct adjustment in hight of the profile element 1 in connection to attachment towards the bedding.
When the profile element 1 is insulated the mounting is made easier by having the insulation 3 slotted in the upper edge a to fit in the upper reinforcing flange 2 of the profile element 1 ending in a vertical tip portion directed downwards. The slot in the insulation is always at the same position to make the tip of the inforcing portion 2 of the profile element 1 able to fit in.
Fig. 2 shows how the profile element 1 is insulated by interaction between the tip of the profile element and the slot a at the upper side of the insulation 3. When needed the insulation can be glued towards profile element 1. Thus the upper part 2 of the profile element 1 is bent in an U-shape to ensure the stra- ightness of the profile element and to enforce it, which has an influence on the stability and create a necessary strength to cope with the pressure developed during moulding of concrete. If the insulation 3 is thinner and thus not will cover a slot in a capping profile an angle iron or profile 5 can be mounted on the its inside bearing towards the capping profile. The angle profile 5 also counteract, to a certain degree, the moulding pressure of the concrete. If a thicker insulation 3 is wanted it can easily be increased inwards without affecting the standard slotting of the insulation. Alternatively the slotting in the capping profile is sealed using a tape..
In fig. 3 flexible, adjustable braces 6 are shown making the profile element 1 able to withstand the pressure from moulding. The braces 6 can easily be adjusted without complicated tools, which is necessary to be able to use the one and same braces for different hights of floor deck forms. The adjustable braces 6, preferably arranged each 60 cm, also allow a readjustment on the working site to ensure the vertical line when mounting an external curtain wall.
In fig. 4 a shorter variant of the profile element 1 is shown for use without connecting and where special profiled angle irons 6 and 7 are used to create the underlaying element having a telescopic function - here at an external curtain wall A - for a final attachment of the profile element 1 at a correct level for the actual hight of the moulded floor decking. A withdrawl of the profile element means that an external insluation can be applied.
In fig. 5a the profile element 1 with vertical slots 9 is shown, which slots 9 extend from the upper edge of the element 1 and down towards the upper edge of the curtain wall. Also openings 8 can be seen here in the upper portion 2 of the enforced area of the profile element 1, which means that a H-strut 10 shown in fig 5b and 5 c with accopanying angle flange 11 can be pushed down and locked inside of the profile element 1 - fig. 5d. That is, the H-strut 10 is pushed down along the outside of the curtain wall. In this way a bracing of the profile element 1 is achieved to withstand the moulding pressure from the concrete. In this case there is no need for a truss beam or brace 6.
The H-strut 10 is designed in such a way that the upper part of it is adapted to the common rack poles, which easily can be mounted in the H-strut.
Finally, fig. 6 discloses how a fasade board 12 have been mounted in connection to the prolfile element 1 by using a prime distance profile 13. It is here about a prime mounting of a fasade board, i.e. there is an air gap between the fasade board and an inside wall element. This construction will principally el- eminate the problems of damages caused by moisture in connection to outer fasade boards.
The invention is not restricted to the shown embodiments but modifications can be done within the scoope of the following claims.
