Definitions

  • the present invention relates to a suspended support structure for wall formwork which leads to substantial advantages over what is currently known (see FR 1 562 186 A ).
  • Suspended structures for wall formwork are to provide means enabling operators who construct formwork to do so as the wall is being built, thereby increasing the height thereof.
  • double-type structures are used, which allow elevated heights for manipulating the formwork to be achieved.
  • said structures Apart from their work platform or upper "console”, said structures have a substantial projection on the lower part or second "console", allowing work to be carried out on portions of the wall which are located below the work platform.
  • these types of structures display a particular problem due to their large dimensions which hamper the mounting of the structure onto the building work by means of lifting cranes, particularly in the initial stage when hoisting the structure off the ground, where it has been assembled, into its position so that it can begin its work.
  • the operation of lifting is complicated due to the inadequate transverse rigidity of said structure, which is simply to be coupled, via suspension, to the wall which is being progressively concreted.
  • the present invention is also intended to cover important safety aspects of the currently known double consoles, since, on reaching substantial heights of approximately 6 metres, the part of the structure below the work platform itself presents safety problems for operators who have to work on it and who possibly have to move from the work platform to the said lower platform, since a height of 6 metres can be dangerous should a member of the workforce fall therefrom.
  • the present invention is based on forming the part of the structure which is located below the work platform by means of a plurality of shorter portions, of 2 metres for example, an auxiliary work platform being located on each one and said portions being articulated to one another, in such a way that the rear part of each portion, in other words the part adjacent to the wall being constructed, to which the auxiliary work platform is fixed, is articulated at the upper end and lower end, whilst the front part of each portion is, in the initial stage, detached at its lower part and articulated at its upper part, thereby allowing free movement and adaptation of the entire structure in the stage of lifting from the horizontal position to the vertical or suspended position.
  • the upper part of the console which supports the formwork panels, is displaceable in order that the formwork panel assembly can be displaced backwards, and away from the part of the wall which has already set, and forwards, in order to take up the working position.
  • Said formwork panels are also vertically displaceable, for the purpose of adjusting the working position thereof.
  • the support structure for wall formwork comprises an upper module 1 for carrying the panels 2 for wall formwork and a work platform 3 as well as posts 4 for safety rails, said module extending downward into a plurality of portions or modules articulated to one another and disposed one after the other, as indicated by reference numerals 5, 6, and 7, each of which is approximately 2 metres high and has an auxiliary work platform, indicated by reference numerals 8, 9 and 10 respectively.
  • the entire structure is to be suspended on the wall, as the wall sets.
  • anchors for example 11 and 12, are fixed to the wall, thereby allowing the structure to be suspended by said anchors.
  • the structure portions or modules 5, 6 and 7 have a predetermined height of approximately 2 metres, for example, to prevent risks of falls and thereby improve safety in each portion, since the height of each does not pose any particular danger for staff with regard to a having a fall, which does happen with current portions which are up to 6 metres high.
  • modules 6 and 7 are articulated to the front and rear platforms which correspond thereto.
  • the structure can be easily lifted by means of a crane, said modules being articulated to one another.
  • the front elements of each module are fixed once the structure has been vertically positioned, as will be explained in more detail hereinafter.
  • Each of the modules 5, 6 and 7 is in the form of a cage, which, in the case of module 5 is formed by a minimum of two end elements, as shown in Fig. 1 , formed by a rear arm 13 which is adjacent to the wall, a front arm 14 opposite the wall and the support 15 for the main or work platform and the lower support 8 for an auxiliary platform.
  • the arm 14 carries supports 16 and 17, in a variable number, to incorporate safety rails.
  • the upper module 1 has a frame 18 for supporting the formwork panel or panels 2, said frame 18 being swivel-mounted about a lower pivot point by action of an adjustable brace 19 incorporated between the support 15 and the said frame 18.
  • the formwork panel assembly 2 can be easily detached from the wall, which has already set, to begin a new cycle of lifting the structure supporting the formwork panels to a more elevated position.
  • the frame 18, together with the panels 2, can be displaced vertically and horizontally so as to be positioned exactly vertically, allowing them to possibly overlap the already built wall as well as achieve sufficient pressure to seal the lower part of the formwork panels, facing the part of the wall which has already set.
  • Fig. 9 which shows the threaded screw 30 for horizontal displacement and immobilisation, which can be displaced horizontally and push on the formwork panel 2, which has the vertical plate 31 for frontal coupling thereof to the adjacent part at the upper edge of the concrete wall 32.
  • the arrangement shown in the figure provides a seal, thereby preventing seepage when the concrete is poured.
  • Fig. 1 all the most important elements of the different modules which form the structure have been numbered and described in a lateral elevation. It must be understood, however, that said modules adopt a three-dimensional cage structure as is shown in the other views, particularly in Figs. 2 and 3 , in which the same numerals have been used as in Fig. 1 , numerals with primes designating the elements in a symmetrical arrangement in each module.
  • the back arms of module 5 are designated by 13 and 13', the front arms by 14 and 14', and the position-adjusting braces by 19 and 19', etc.
  • Figs. 4 , 5 , 6 , 7 and 8 show construction details of one of the elements of module 5, in other words, the first module located below the support 15 of the platform.
  • the specific embodiment of one of the elements of module 5 comprises support cross-members 8 and 15 for an auxiliary platform and for the main work platform respectively, as well as a rear vertical arm 13 and a front arm 14 carrying supports 16 and 17 for safety rail elements.
  • elements 8, 13, 14 and 15 are rigidly interconnected by a reinforcing brace in the form of a bar 20, forming a strong frame which, with the arrangement of the corresponding platforms and rail elements, together with another symmetrical component on the other end of the formwork support structure, forms the modular component 5 with a generally cage-like structure, which is the first element below the work platform.
  • the horizontal component 8 extends on the side adjacent to the wall in a projection 21 which abuts the wall and is complemented by another projection 22 at the height at which the brace 20 is fixed and a third upper projection 23, which is an extension of the supporting cross-member 15, and a lower reinforcing plate 24 carrying an angled groove 25 with the rounded vertex directed upwards, carrying a pin 26, which at one end of the groove prevents the support structure from being accidentally disassembled from the formwork, whilst at the other end it allows the structure to move freely and vertically so that it can take up another position at a greater height.
  • the cross-member 15 carries the post 4 for supporting the rail elements, in such a way that said post 4 is mounted in an articulated manner on said cross-member 15, having two stable positions, one of them being shown in Figs. 4 and 5 , to allow the posts 4 to function as supports for the rail elements and the other being the folded-down position which will be described with reference to Figs. 6 , 7 and 8 and facilitates transport and storage.
  • Figs. 6 and 7 show the element for a module with a shorter vertical arm 13.
  • the collapsible feature of the posts 4 carrying the rail elements is equally valid for this short arm version or for the long arm version shown in Figs 1 to 5 .
  • the post 4 is articulated on a pin 27 and has a second opening near to its end with a second pin 28 which can be disposed as shown in Fig 8 , for the folded-down position, or can be disposed so as to pass through the opening 29 located near to the end of the cross-member 15, vertically immobilising said arm 4 as shown in Fig. 7 .
  • the lower modules 6 and 7 are articulated and consist of rear arms 35 and 36, front arms 38 and 39, articulated at their ends as shown, and the auxiliary platforms 8, 9 and 10.
  • the wall formwork support structure is suspended from anchors which are fixed on said wall, for which purpose the adjacent ends of the structure carry plates with recesses for the said anchors.
  • One of said plates 34 is shown in Fig. 5 and equipped with an opening 35, the entrance of which is directed downward and is aligned with the anchors which have been previously fixed to the wall, to suspend the formwork support structure.
  • the disclosed formwork structure allows simple and rapid construction of the structure which can be safely raised using a crane, the fixing of some of the articulated parts being completed once the structure has been partially raised, avoiding currently existing disadvantages.
