Fastening means for supports of falsework in concrete construction

The invention relates to a novel fastening device for falsework parts (carriers), which are particularly suitable for use is intended in dismantling metal formwork.

The widespread and increasing use of reinforced concrete has led to the development and creation of formwork and falsework of various types, from the simple to the base

of wooden planks, which are made of the same on roughly timbered scaffolding Material to be attached / up to further, more modern, including metallic and demountable, in which a complete material recovery and also reduced Switch-on and switch-off times can be achieved.

The fastening device described here is used to supplement a formwork consisting of modules of the specified general way in which by means of this device an optimal fastening of the falsework parts supporting the formwork, Trestle supports, horizontal beams (spars), etc., is achieved, while at the same time the normally problematic the expansion of the mentioned falsework parts and the formwork panels themselves on a simple operation in the first 3 to 4 days of concreting is limited without in any way affecting the structure of the falsework, that about the roughly necessary to set the concrete Remains for 21 days.

Generally speaking, the proposed device comprises pairs of elements consisting of a fork and a spacer (Separation profile) are formed. For this purpose, the fork mentioned is formed from a U-profile that has a has an open neck at the top and bottom for the purpose of telescoping it onto the upper one, too

tubular part of the vertical part of the support frame the formwork can put on.

The fork then slides through the aforementioned neck onto the vertical part and sits on it in the required position Height by the spacer, which simply consists of a U-profile piece that is provided with a split pin to define the arrangement including the aforementioned part of the support frame below the fork.

In an ideal form, this spacer has at least one beveled edge, for example towards the upper end to facilitate its later removal by means of a blow, which also causes the fork to fall out and thus immediate Includes formwork and dismantling of the support structure girders.

The details and features of the invention proposed here will be clarified by the following explanation with reference to the attached Drawings better set out that illustrate a preferred embodiment, namely shows

Fig. 1 is a diagrammatic view of a prefabricated formwork made of metal and which can be dismantled, which is the one described here Fastening device used; «

Fig. 2 illustrates the sliding fork and

Figure 3 is a view of the spacer.

As can be seen from the drawings, the invention includes fork 1 of U-shaped cross-section with a central tubular! and hollow neck 2 and, as shown in Fig. 3, on either side, i.e. at one and the other end of the cavity may have a pin or a hole 3 to enable correct insertion and fitting of the carrier 4, the to for this purpose a matching hole or pin must be provided around the pin or the hole in the spacer to record. The pins or drill holes can be distributed alternately / fl.

However, this pin or hole is not indispensable and according to Fig. 2, the fork in relation to its fastening and sliding form can be run without them.

The necks 2 are inserted into the tubular parts 5 of the trestle supports and lie directly on the traverse 6 and that of you opposite projection 7 (left part of Fig. 1 in the disconnected position) or on the spacer 8, the this in turn does this on those parts (switched-on position on the right in Fig. 1).

This Abstanshalter has a pin with holding chain 9 that prevents the accidental falling out, and has a chamfered (ramped) top, to facilitate its removal during stripping released whereby the fork and the removal of the carrier is made possible. 4

Claims

Claims (4)

Claims 1. Fasteners for girders for use in prefabricated and demountable formwork for falsework in the Concrete construction, characterized in that it is formed by a U-shaped rolled profile Comprises fork, which receives the ends of the carrier (4) in its interior and in the middle of an open top and bottom Neck (2) is present, by means of which it telescopes on the upper part of the vertical parts the braces of the falsework scaffolding is attached. 2. Fastening means for carriers according to the preceding claim, d a you rch gekennzeichne t, that optionally in the middle part of the groove formed by the U-shaped part of the fork on one side and the other On each side there is a pin or drill hole to be provided that can be inserted or placed on just as many Holes or pins are used, which are provided for this purpose on the edges of the supports that they use in this way stabilize besides supporting. 3. Fastening means for girders according to the preceding 409851/0351 Proverbs marked by the Arrangement of a spacer, consisting of a U-profile piece, which is used to stabilize its position with is provided with a pin and comprises the end of the support below the fork mentioned, which it in the formwork position with the pin held in place with a chain to prevent it from accidentally falling out to prevent. 4. Fastening means for carriers according to the preceding claims, characterized in that that one of the ends of the spacer supporting the GabaL is preferably beveled (ramp-shaped), so that when stripping its removal by means of a Impact is facilitated, which in turn a lowering of the fork by sliding and thereby also the arranged on it Girders and formwork panels causes. 409851/0351 Blank page
