Scaffolding

The furnace relates to scaffolding of the type which is referred to below with "the type described", which consists of a There is a number of tubular, upright components, each in a number of different heights along their length are provided with a group of sockets, with the individual sockets of each group spaced around the perimeter of the upright Components are distributed and each serve a plug-in element take up, one of which is arranged at both ends of a transverse part, for example a transverse bar element or stiffening element, which extends between two spaced upright components.

For example, know the plug element by a wedge-like T ° il be formed, which ar. the 3näe of the crossbeam part in p.esug, movably mounted on this transversely to its length is, as 3ies for example in a criti-oher patent TTr. 1 13C 562 and German patent Kr. 1 634 321 ict, or this plug-in part can be formed by a pin be, which extends transversely to the longitudinal extent of the transverse beam part, as described in the British patent ITr. 935 912 is described.

Such an arrangement is in those cases with scaffolding Occurring from time to time, a disadvantage in which it is desirable to increase the overall height of the upright parts adjust.

The simplest way to enable such an adjustment is that the upright parts are telescopic The construction is obtained by providing two tubes of different diameters, the one with the smallest diameter is axially slidable in the larger diameter ear, and thereby, that appropriate facilities are provided in order to fix the two bores against relative axial movement when the upright component is at the required viheeight was discontinued.

However, such an arrangement cannot be satisfactorily applied to the scaffolding of the type described above . * ~ r ^ clT ^ r ^^ r. ^ rHr-A ⁰ :

to overlap different distances and thus to achieve the required height adjustment.

According to the present innovation, at least one of the socket groups on the upright component is each designed as a one-piece body with a central opening through which the upright component extends in slidable engagement with 6em body, so that this body in both axial directions over the length of the upright member is slidably adjustable, and means are provided to restrain the body against downward movement with respect to the upright member in any of a number of positions of axial adjustment and the integral body forming each group of bushings comprises a number of channel-shaped bushings _? wherein the free ends of adjacent legs of circumferentially adjacent channel-shaped sockets are integrally connected to one another, so that the sockets are formed as radial continuations of the central opening and Öie free ends of the legs are in engagement with the upright component.

Such a socket group can thus be dimensioned exactly like a socket group previously used and attached to the upright component in a fixed position. It follows that scaffolding parts of standardized length, as ßie are currently used, also in connection with the Base groups according to the invention can be used.

The holding devices can wedge devices on the adjacent Have the end of the coupled transverse part, which in the driven-in state has a stop surface that is attached to such a The end of the transverse part is provided in a clamping engagement with frictional engagement with the outer circumference of the upright component thus force the one-piece body against a downward one To hold movement in relation to the upright component.

This feature of the innovation is based on the first recognition of the fact that the clamping pressure between part of the transverse part and the outside of a component on the right, which is derived from the wedge-like clamping means which are used to secure the plug element in the socket, such as this is described in the two patent specifications just mentioned, is sufficient in itself to fasten the associated bushing and thus a group of bushings at the required height to the upright Bswtsil »without it being necessary to weld the bushings to this component.

The abovementioned stop surface can be formed by a surface of a wedge part, which the above-mentioned plug element may form, with the opposite surface serving to a ^ n wedge-like engagement with part of the socket or with a pin at the end of the transverse part so as to form part of the male element, like this is described in Applicant's British Patent No. 1,278,596.

Alternatively, the stop surface can be formed by the free edges of the upper and lower wedge parts, which Arms carry, as described in the above-mentioned German Patent No. 1,684,321, or it can carry this surface through one face of a downwardly directed pin carried by the end of the cross member, as in that in US Pat British Patent No. 985,912.

The innovation, as far as it has been described so far, is particularly applicable to cross members in the form of themselves between the to attach stiffening elements extending upright components via the bushings to the upright components, such stiffening elements do not have to bear external loads, such as part of a scaffolding board, as is the case with transom elements, and it is

assume that in this application, the above "described clamping engagement under frictional engagement is sufficient to the socket groups to hold against a downward movement in relation to the upright component on which they are arranged.

The same applies to the case of many who are comparatively lightly burdened Crossbar elements too, however, need the sliding adjustable bushing groups in the case of heavier loads Cross beam element to an additional or alternative support on the upright Bauxeil, which by other appropriate equipment can be created by, for example, separating aie groups of bushes with some form of drivable Be provided wedge, which is suitable for an additional clamping engagement between the socket body and the outer circumference of the to ensure upright component or, for example, in the socket body with a clamping screw or with Threaded bolt is provided, which is suitable, in the tightened state, an additional clamping effect with frictional engagement with its inner end on the outer circumference ües upright Exercise component.

A much more positive, alternative or additional support kaü-n created by the fact that the upright component at intervals, for example at tight intervals along its length, with load-bearing stops which are for a positive load transfer engagement are formed with a bearing part, which is connected to the Axialgleitwarenbuchsengruppe or is assigned to this.

For example, such stops can be formed by a number of holes which extend diametrically through the upright component and which receive a removable pin which is inserted through corresponding holes in a comprehensive KrrnffianirhUek in Tn «-h trncronder Δηίαοτο m4 -h dar Un- ta-raai -ho Has

Socket body passes through.

The collar can, if desired, be formed integrally with the body be, for example, in which it is welded to this.

By using such devices to hold the body in its position on the upright component, can the innovation can be applied to types of scaffolding of the type described, in which the transverse part with the base group is not connected by devices that come into direct engagement with the upright component, but in a way that is based only on the clamping of the cross member in the socket, as is the case, for example, in the table Patent No. 1,163,532 of the applicant is described.

The present innovation achieves the following advantages:

1) Each group of sockets which, according to the innovation, are axially adjustable can be arranged at any non-standard height along the length of the upright components, and thus the increased versatility of scaffolding of the type described,

2) The upright components of a telescopic construction that can be adjusted in the vertical direction can be equipped with a ¹ ? or provided with a plurality of axially slidable groups of bushes on the tubular part of smaller diameter, ie the inner part, without thereby limiting the extent to which such a component can be telescopically displaced within the outer part and thus adjusted with respect to this part .

3) If desired, this construction allows the upright components to be made up of pipe sections of the same outer diameter are made or formed, which are mutually in axially aligned relationship by short pipe sections un-

different diameters are connected to thus sine telescopic Adjustment of the assembled upright components at a number of locations along their length allow, the bushing groups are all mounted on the tubes of the same outside diameter, in this In case all cross members, for example cross beam elements and stiffening elements, can have a length that suits the one Corresponds to the outer diameter of the upright component.

Alternatively, taking into account the simplification of the telescopic adjustment of the upright components, such as As achieved by the present invention, it can now be economical to construct the upright parts from pipe sections to produce two different diameters, these being telescopically accommodated in one another, and where the Bushing groups of at least the inner tubes, d. H. the pipes of smaller diameter, according to the present innovation, lengthways ■ whose longitudinal extension are slidably displaceable.

The innovation is explained in more detail below with reference to embodiments illustrated by way of example in the drawings. It shows:

is in order to thus with a corresponding inclined surface of the Wedge to work together ~ This is how one serves one additional wedge or such additional wedges serve to hold the socket group against a downward To support movement in relation to the upright component.

As a further option, instead of one or more additional Provide sockets for receiving such additional wedges, one or more of the sockets 11, 12, 73 and 14 formed so that they are used in the same way can, but in this case the socket group would only serve to attach a smaller number of cross members to couple the upright component.

As another example of one way of using a collar and pin arrangement such as that shown in Figs is illustrated, the base body could be provided with a clamping screw or a threaded bolt, v / which to do so serves, an additional Klemmei ^ handle in the tightened state with frictional engagement at its inner end with the outer circumference of the upright component. Such a modification would only require one or more radial arranged internally threaded bores are provided in the socket body and corresponding screws therein or bolts are arranged.

7 shows a type of arrangement of the modified construction according to FIGS. 5 and 6, when this is done with a transverse part in the manner is composed as it is in the British Patertschrift No. 1 163 533 of the Aninelderin. With this arrangement a socket group 10 is supported on an upright component 61 by means of a collar 63 and an associated pin £ 5, which passes through aligned holes in the collar and the upright member and a crosspiece 62 is clamped to a socket 11 by means of a part 73, which

- 15 -

rather is received captive in a slot 69, which in a connecting part 68 is formed. The connecting part 68 has a downwardly directed plug element in the form of a Pin 70, which is received in the socket 11 and is located at a distance from the upright component 61. Of the Key 73 engages the outer surface of sleeve 11 and pulls pin 70 into keyed engagement with the interior lying surface of the socket 11.

In this arrangement, the socket group on the upright component is completely held in place by the collar 23 and the pin 25. The illustrated in Fig. 8 arrangement, but showing the modified construction of Figs. ■ and 6, wherein the i support formed by the collar and the pin is replaced by wedge means which are provided at the end of the supported by the socket group cross member.

In Fig. 8, the socket 11 takes a pin 84 and a key as described in the applicant's UK Patent Specification No. 1,278,596, carried by a transverse member 80 are. In use, the wedge 85 is driven downwardly about the pin 84 outwardly against the inner surface of the socket 4, while the wedge itself is thereby forced into frictional engagement with the upright component 81 will that cooperating inclined surfaces cooperate on the wedge and the pin, which are common than that in the socket recorded plug-in element act, wherein the surface of the wedge which comes into engagement with the upright component, serves as the abovementioned stop surface which is provided at the end of the transverse part.

All of those mentioned in the description and in the drawings recognizable technical details are important for the innovation.
