Abstract

The panel is of the type which comprises a laminar shuttering plate (1) which can be curved to determine the surface of the shuttering, this laminar plate (1) being associated on one of its sides with a plurality of vertically arranged beams (2) of substantially open trapezoidal box structure and characterised by the arrangement of shafts (5) operating and synchronising adjustment of the curvature of the laminar shuttering element between each of two panel beams (2) and parallel thereto, each pair of adjacent shafts (5) being associated with a single operating mechanism associated with the intermediate beam between the said shafts, a mechanism which can cause the two shafts (5) adjacent thereto to rotate, the said operating and synchronisation shafts being joined by means of connecting rods (24); articulated to the corresponding adjacent beams to change their relative position and thereby the curvature of the panel.

Description

ADJUSTABLE PANEL FOR CURVING WALLS CURV DESCRIPTION The present invention provides u stable for the formwork of curved walls, which have characteristics of novelty and activity with respect to what is currently known.

The adjustable panel for the shuttering of the object of the present invention is of the casing of steel sheet bodies or open trapezoidal beams, arranged in the generatrices of the curved surface, laminar fixed or shuttering plate, which will adopt It is necessary for the wall to be made and its parts are connected to each other in order to allow the adjustment of the angular arrangement of the trapezoidal bodies or beams for its desired curve.

In U.S. Pat. A. 7048249 is given to co-ordinate of adjustable circular type of this type, and mechanical ace between the different devices of each spar.

In other known systems according to the same one there are different types of elements of anch also characterized by the cumbersome use of the low precision of the bending that is considered laminar of formwork, which can adopt alab In order to solve the problems, it has been devised, after testing and experimenting, an adjustable panel for the wall formwork, which allows for a quick adjustment of the formwork to the curve of handling a very small number of synchronization points along each longitudinal beam. the formwork of the formwork, so that an adjustment with a great uniformity of the curv direction of the height of the formwork panel is achieved, avoiding this by loss of parallelism between To achieve its objective the present i see the arrangement of synchronization axes that to superior parts e. bottom between two stringers d two successive stringers. In this way, it is possible to follow a rapid and effective adjustment of the formwork of the upper and lower parts of the deformation caused by warping on the electronic board.

The synchronization axes can be aligned on their own geometry axes, and they can be constituted in a rotating crankshaft fashion on an eccentric axis of both upper and lower pivots, followed by a more favorable construction in terms of the stresses generated.

For better understanding, explanatory drawings of one embodiment of the adjustable formwork of the present invention are attached, which is explained on the basis of said drawing explanatory and non-limiting character.

The invention is defined by claim The dependent claims define destionals of the invention.

As seen in the figures, the curved girders endowed with the object of the present invention come from multiple panels joined together and each susceptible of curved or shown in FIG. 1, including raised. They also have hooks of suspension and descent, such as the hook -16- of the f It is an essential characteristic of the object-adjusting panel object of the present invention to adjust the radius of curvature of the element by aligning the adjustment elements to the generatrices of the panel in order to avoid the twisting of the parallelism between generators. This is the arrangement of axes -5- parallel to the panel and arranged one between each two stringers, represented in figure 1. Said longit axes are rotatable by the action of adjusting arms -6- which are housed in one of the larguerán directly on two axes longit acentes -5- and these, through the ilcarán articulations, act on the adjacent gueros lateral walls.

As shown in Figures 3 and 9, each arm at length -6- has an external, hexagonal preferematic structure, as this corresponds to It should be noted that the exemplary embodiment by means of the inner screw and displaceable rods -10- and joints at the ends -12- and -13- is a preferred construction example, since the connection between a central control and the axes of aj should be achieved by any other conventional device.

The arm -6- is fixed with capacity of the stringers -2-, for example, medi position shown in figures 3, 7 and 9 med lar -15- and the corresponding groove although, such understand, could also be achieved with any mounting by means of an encircling sleeve, c * The longitudinal axes -5- parallel gears are related to the adjacent spars -24-, as it is to observe in them f.

In the upper part of the axes -5- there are actuating elements which act in the lower part, the connection between and the longitudinal members -2- is analogous to that described above by means of connecting rods -inclined in the upper part, as well as transversal transverse wings -17-.

As indicated above, the chronization can be rotatable on their propmetric or preferably they can have crankshaft arrangements, as will be shown in figures 4, 9 and 12. In the figures, it can be observed that fixed way to one gears -2- which has the drive shaft - half of the upper and lower bars -17-, are mounted in the form of a medium crankshaft - which are articulated by vertical pivots erminan an axis of eccentric rotation. The crankshaft-like assembly is also shown in the section of figure 16, with the upper part and the lower part being equally visible.

Figures 17 and 18 show the pentagonal prismatic structure of lateral faces - substantially perpendicular to the lame element 1 -, and two other faces -27- and -28- inclining to the lateral faces -25- and -26 and one last perpendicular to said side faces 25 and possibly parallel to the web The complete by means of two oblique wings 30 and by tabs and screws to the lamered element 1. Said reinforcing columns of the 1 a provided with openings for jaws or other type d are like the upper longitudinal openings -3"keyhole" rturas -33- and others similar.

In Figures 13 and 14 is observed in the construction of a sidebar -3- abi straight faces, giving rise to a smática structure that on its front face has a gitudinal -46- for the entry of one of the mandi vertical clamping jaw of an adjustable panel with another located in the upper part, such as in the detail of figure 11. The cold face available the fixation by means of screws -4 laminar formwork - 1-, as shown in FIG. I observed 14. The fastening of the stringer to the workpiece element - 1- is done on the one hand by means of screws - 42 - which fix the flange -41 to, by means of long transversal screws - the rods are prevented and incorporated into the face of the shuttering element -1 - by means of a head in - which is flush with said panel. The screws are fixed by means of nuts -49-, which, likewise -42-, are accessible by the part of the operator, which allows easy access to said maintenance measures of the panel, dismantling of the load -1- after having made one or several replacing it by a new low sheet. It should also be taken into account that the screws are accessible from the post face of the formwork, they facilitate doubly the assembly, since on that face the dirt produced by the concrete pouring is very reduced. dibulas in the double layered internal plates inside the stringers -3-.

The vertical fixation of a panel with otrior is seen in figure 11 by means of a mor one of its arms is fixed to a rod transverse by conventional methods transversely -3- 'and that allows to fix with great solidity of formwork with another element located in erior.

Although the invention has been described based on a preferred embodiment with attached figures, it will be understood that the technicians, after knowing the present invention, produce multiple variations and changes within the scope of the present invention defined in The following claims and ivalents.
