Definitions

  • the present invention relates to the establishing of pre ⁇ ferably temporary supports for exhibition pavilions or other space requiring arrangements, in particular in city areas.
  • cities Normally, most larger cities have a free area suitable for cattle shows, setting up of circus tents and various other activities, but that kind of areas will normally be located at the periphery of the city, whereby they are not optimally applicable in case of more prestiged arrangements.
  • the invention is based on the consideration that almost every larger city exhibits a large wet area that will be per- fectly suited for the purpose, if care is taken to establish a floor construction of the required carrier capacity above the water surface.
  • a simple bridge building technique whereby the large carrier surface is established by building out and laterally joining the required number of single bridges.
  • These bridges may in a simple manner be constructed so as to be individually and then also collectively strongly carrying, viz. by their contact with the underlying sea bot- torn, via support plates of noticeable width, whereby the re ⁇ quired carrier capacity is fully secured.
  • sim ⁇ ple pole tubes as disclosed in WO 92/12295, it is easy to mount the poles by flushing directly through the tubes, and for the present purpose it is an important possibility that the poles can later on be taken up in a correspondingly easy manner, viz. by forcing air or water down through the pole tubes. So far, this possibility has been connected with a possible season conditioned withdrawal of light jetties or bathing bridges, but with the invention it has been realised that the easy demountability may simply be economically deci ⁇ sive for the planning of the entire, temporary construction.
  • Fig. 1 is a perspective view of a platform system estab- lished at a lake area in accordance with the invention
  • Fig. 2 is a similar view of a more differentiated system, shown with added pavilions;
  • Fig. 3 is a perspective view of a basic bridge construc ⁇ tion
  • Fig. 4 is a similar view of parts of a mounting crane
  • Fig. 5 is a top view of a bridge system during mounting.
  • the system shown in Fig. 1 is a large carrier platform 2 established in a river or lake area or for that sake in a sea or swamp area at or near a central city area for the purpose of forming a preferably temporary support for some special arrangement such as a special exhibition or a series of sum ⁇ mer concerts, optionally with added, associated light pavil ⁇ ions.
  • the platform is connected with the seaside through an admission bridge 4, which, as indicated, is provided as an ordinary bathing or boat bridge of double width, or rather as a parallel system of two such bridges, which may each have outer support poles, though with the middle poles in common, as explained in more detail below.
  • the platform 2 is built in a widely corresponding manner, viz. as a very broad row of joined, parallel bridges 6 with bridge units 8 that can be built out from the central bridge and, as desired, mounted rowwise in the length or width di ⁇ rection of the bridge 4.
  • Fig. 2 shows a construction built as a system of mutually bridge connected platforms each carrying a domed conference or exhibition pavilion 12, which has been developed as a spe- cial aspect of the invention.
  • the bridge poles are metal pipes which are mounted by auto flushing , i.e. with the use of the pipes themselves as lasting flushing spears, until it is desired to demount them by a correspondingly simple technique, viz. by forcing air or water down through the pipes.
  • Each new bridge unit is mounted by means of a lightweight crane, which is anchored to the former outermost bridge unit and via a jig carries the new bridge element temporarily in such a manner that this element can be used as a working platform for the flushing down of the next pair of poles, to which the new element is to be secured, while it is also secured to the outer end of the previous outer bridge unit.
  • this mounting technique may be used for bridge building not only longitudinally, but also in the cross direction, as this will just be a question of turning the crane and keep it secured to the relevant bridge unit, whether this is an outer unit or an arbitrary unit of an already established bridge structure, whereby broad bridges - or whole platforms - may be con ⁇ structed as desired, by a combined length and/or width expan ⁇ sion of an already established unit 4.
  • the crane and/or the bridge are designed such that the crane can be anchored for paying out new bridge elements in both the length and cross direction of an already mounted bridge unit.
  • the bridge units have a length bigger than their width, so the mounting crane should primarily be designed to cooperate with the narrow front dimension of the bridge.
  • this will in no way prevent the crane from also being usable for cross mount ⁇ ing, if the base unit is permanently or only temporarily pro ⁇ vided with means for holding the crane, preferably for re ⁇ ceiving base pins of the crane both in the outer pole pipes of the carrier unit and in socket pieces permanently or tem- porarily secured to the sides of this unit.
  • the crane of course, is a relatively heavy unit, but ac ⁇ cording to the invention it may well be divided into two in ⁇ dividual halves for mounting at the respective sides, just as each of these halves may be divided into a chassis portion and a jig projecting therefrom. It is then achievable that the crane in its entirety can be moved, mounted and demounted as well as used by a single operator only.
  • each pair of opposed poles is stabilised by means of a wire or chain cross strutting with a wire or chain tightened between the bottom plate area of the single poles and the upper bridge element area of the respective opposite poles.
  • Fig. 3 shows one end of a bridge unit according to the invention.
  • the unit or element comprises profiled side mem ⁇ bers 20 of aluminium, prepared with bolt holes at the rele ⁇ vant places.
  • the side members are held together by means of a few traverses 22.
  • the side members have interior grooves 24 forming support for the ends of cross oriented boards 26. These boards are mounted on joists 28 resting on the traverses 22.
  • the flooring may be made as pallets, such that the bridge element can be finished e.g. by a laying out of three such pallets.
  • the side members are internally reinforced by bolted plates 30 adapted to receive tightening bolts for outer pipe mounting brackets 32, and these plates are rigidly provided with a strong hook 34.
  • the side members are provided with inwardly projecting bolting fittings 36, by means of which they are joinable with similar elements.
  • the single elements are car ⁇ ried by an end joint with the preceding bridge unit and by two exterior poles in some distance from the opposite end of the element.
  • the poles are pipe pieces 38, which are each provided with a bottom support plate 40 effectively secured by means of a pipe clamp 42 at the relevant place.
  • the poles are flushed down until the bottom plates engage the bottom (even if the latter is not fully rigid) , and when then the poles have been secured to the side members, a chain 44 pre- connected to the pipe clamp 42 is tightened crosswise up to the hook 34 at the opposite pole.
  • these chains are fitted with tightening devices 46 that will enable a very strong tightening of the chains.
  • the bridge elements are brought out as shown in Fig. 4 by means of a light auxiliary crane 50 at either side.
  • These crane sections can be mounted by lowering of a holding pin 52 into the last mounted pole 38 and, preferably, another hold ⁇ ing pin 54 into a purpose related holder 56 temporarily se ⁇ cured at the outer end of the side member 20.
  • the open element frame With the use of the indicated hoisting and running system the open element frame can then be brought to the position shown in dotted lines and from there be lowered into its regular position. From the formerly outermost end of the bridge it is now easy to work out the required bolt joining of the end plates 36, and thereafter the said flooring pallets may be successively laid out on the new section.
  • this new bridge element can be used as a working platform for the flushing down of its own carrier poles 38.
  • Each pole is placed in an approximately correct po ⁇ sition and is then anchored in a hoist strap or claw 58, the hoist wire of which is arrested such that the pole pipe can now be handled in weight relieved condition. It is then placed more accurately, i.e. vertically at the mounting place next to the side member 20.
  • the crane is provided with an openable, upper guiding ring 60, which, when the crane is correctly mounted, is located vertically above the prepared joining area, whereby the pole pipe can be caught in this ring, which is then closed.
  • the mounting bracket 32 is mounted loosely about the pipe, and then the flushing down is effected, now with the pipe suit- ably guided. After the flushing down, the bracket 32 is se ⁇ cured rigidly. When also the other side is ready, the floor ⁇ ing pallet in the working area is taken up and the said mounting and tightening of the cross chains 44 is effected. Thereafter the work can proceed with the next section, the auxiliary holder 56 and the crane being moved out on the just mounted section.
  • the method is not limited to such a forwardly progressing mounting, as it is possible to cross turn the crane equipment as schemati ⁇ cally shown in Fig. 5.
  • the supporting crane chassis may have a length of 60 cm, whereby, if bridge elements of 2 m are used, there will be sufficient space to place a bridge ele- ment 64 lengthwise and cross displaced in front of the cross mounted crane without the bridge element overbalancing. Thereafter, the new element can be hoisted out and mounted fully analogous to the above description.
  • the guiding ring 60 on the crane can be displaced along the jig and is thus mov- able to a standard position suited for such a cross mounting.

Abstract

De manière à établir des zones d'activité temporaires dans des villes ou à proximité de celles-ci, on propose d'utiliser des zones immergées existantes sur lesquelles on installe des plates-formes (2, 10) à l'aide d'une technique généralement connue servant à bâtir des ponts légers, lesquels sont ici montés côte à côte de manière à former un grand plancher. Un grand nombre associé de mâts (38) de pont tubulaires assure une capacité élevée de sustentation, ces mâts étant faciles à monter par enfoncement direct tout en étant également, ce qui constitue une caractéristique importante, faciles à démonter en étant forcés de remonter sous l'action d'air ou d'eau sous pression. On peut effectuer le montage et le démontage en utilisant des matériels auxiliaires simples, notamment une grue commandée par une seule personne et possèdant des moyens de guidage de mâts (58, 60). On obtient un degré élevé de rigidité dans cette construction en utilisant des entretoises croisées (44, 46) sous forme de chaînes fixées individuellement entre les mâts (38) de chaque paire de mâts. On peut effectuer ce montage avec un nombre peu élevé de composants standards et sans aide provenant du côté de l'eau.
