Abstract

Formwork panel, of the type that are constituted by a frame (1) and a board (2) that fits into a receptacle defined on the front face of the frame (1), characterized in that it incorporates an elastic element (4) linked to the edge of said board (2), which is provided with a lateral bulge (5) on its upper edge in correspondence with the front face shuttering board (2) with which it is flush, to cover possible clearances that could appear in the setting between the board (2) and the frame (1).

Description

Formwork panel

Object of the invention

The present invention relates to a panel of formwork of the kind that are constituted primarily by a frame or frame on which the formwork board is mounted, of wood or plastic

It is an object of the invention that the panel of formwork arrange the appropriate means to achieve an adjustment perfect in the union that is established by fitting the board into the frame, so that any possible elastic is absorbed clearance in the joint along the entire perimeter, eliminating the need to provide stuffed silicone accessories or any other material that can come off.

Background of the invention

The formwork panels are constituted by a metal frame or frame on which the board is mounted, of wood or plastic resistant to the concrete that will constitute the formwork surface, that is the surface that will be in contact with concrete. They are currently being used composite sandwich boards, 100% plastic, consisting of a core of recycled plastic material and outer sheets of reinforced plastic. Composite sandwich are also used constituted by a core of plywood to which adhere external sheets of plastic and wood fiber.

In order to receive the board, the frame it presents on its front face a peripheral step on which the board that is normally linked is supported and fitted by screws.

The coupling between board and frame is not perfect and implies the existence of gaps between both elements which must be filled, usually using silicone. The slack it is not uniform throughout the periphery of the board and there are areas in which is too narrow, which is why silicone does not penetrates sufficiently, does not reach the bottom of the slack. To the perform the first decoupling operation, the silicone that does not has been sufficiently fixed in the clearance can be detached easily, so that the place it occupied can be filled with concrete in the following formwork work.

The introduction of concrete into the joint determines that the formwork face loses its flatness and that they occur traces or signs on the surface that is concreted with these formwork panels.

Also, when the board needs replacing, the operation is going to be hampered by the existence of concrete accumulated on the board, which must be removed.

The resolution of the exposed problem it is therefore the object of the invention that below It is described.

Description of the invention

The formwork panel proposed in this invention covers the described expectations contemplating how fundamental objective the optimization in the adjustment that is established between the board and the formwork frame.

The solution advocating this formwork panel is to eliminate the slack that could exist in the union between the board and the frame, which was previously resolved with the additional supply of sealing material easily removable

The elimination of this slack is achieved by elastic means linked to the edge of the board, which ensure the absorption of possible imperfections that may appear in the fit between board and frame throughout the entire perimeter.

More specifically the formwork panel contemplates preferably the incorporation in the non-formwork face of the board of a perimeter recess of constant width intended for receiving the elastic element of, for example, elastomeric material, such as silicone or polyurethane, of constant section like L, fixed by one wing to the aforementioned recess and by the other wing to the edge of the board. One way to obtain the union of the elastic element to the board is overinjecting the elastomeric material on the own board.

The elastic element incorporates on the edge upper lateral wing a lateral bulge designed to absorb possible slack variations that could exist along the perimeter between the board and the frame.

It is expected that the aforementioned bulge Flush with the formwork face of the panel to the object of provide continuity of this surface to obtain the desired flatness on the surface concreted by the panel.

The frame generally has, on the face posterior, a series of ribs or braces and in its front face a large receptacle sized to receive the board with its elastic element attached to its edge perimeter.

The elastic element measures, and more specifically the bulge, will be established so that you can cover the maximum predictable clearance, as well as the elasticity of the material will be such that it allows to firmly snap the board in the entire frame receptacle.

This way you get the element elastic permanently constitute the joint between board and frame.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a previous view in perspective of the formwork panel in which the board is observed mounted on the frame with the intermediation of the element elastic.

Figure 2.- Shows a rear view in formwork panel perspective.

Figure 3.- Shows a detailed view of a section according to A-A practiced in figure 1, in the that the frame and the board mounted on it and the elastic element associated with the board that covers the possible gaps that could exist between board and frame.

Preferred Embodiment of the Invention

With reference to the figures, a then a preferred embodiment of the panel formwork that constitutes the object of this invention.

The formwork panel, as seen in the Figures 1 and 2, is the type of which conventionally they constitute by a frame (1) and a board (2) that fits in a receptacle defined on the front face of the frame (1), counting said frame (1) normally with ribs or braces of stiffening (3) on its rear face.

The invention focuses on the fact that it has provided on the formwork panel, more specifically on the board (2), the incorporation of an elastic element (4) linked to the edge of said board (2), which is provided with a bulge lateral (5) at its upper edge in correspondence with the face previous formwork of the board (2) with which it is found flush, to cover possible gaps that may appear in the adjustment between the board (2) and the frame (1).

It is preferably contemplated that the element elastic (4) be configured with an L-shape, with a side wing that incorporates the lateral bulge (5) linked to the edge of the board (2) and a rear wing linked to the rear face of the board (2).

To facilitate the integration of the element elastic (4) with the board (2) is provided that the face back of the board (2) incorporate a perimeter recess (6) of thickness and width matching those corresponding to the wing back of the elastic element (4) to receive the latter.

The elastic element (4) is adhered forming body with the board (2) preferably because it is obtained in a overinjected operation of the elastomer that forms it, silicone or rubber, on the edge itself and recess (6) of the board (2).

Claims (4)

1. Formwork panel, of the type consisting of a frame (1) and a board (2) that fits into a defined receptacle on the front face of the frame (1), characterized in that it incorporates an elastic element (4) linked to the edge of said board (2), which is provided with a lateral bulge (5) at its upper edge in correspondence with the front formwork face of the board (2) with which it is flush, to cover the possible clearances that could appear in the setting between the board (2) and the frame (1). 2. Formwork panel according to claim 1 characterized in that the elastic element (4) is configured in an L-shape, with a lateral wing incorporating the lateral bulge (5) linked to the edge of the board (2) and a rear wing linked to the back side of the board (2). 3. Formwork panel according to previous claims characterized in that it incorporates a perimeter recess (6) of thickness and width coinciding with those corresponding to the rear wing of the elastic element (4) to receive the latter. 4. Formwork panel according to previous claims characterized in that the elastic element (4) is injected over the board edge itself (2) and recess (6).
