Description

Technical Field

[0001] The present invention aims to provide a device for positioning formwork for concrete wall construction, which allows positioning of the formwork from one side of the wall without the need to approach from both sides of the wall, thus facilitating subsequent placement of the formwork for pouring the wall. The present invention can be applied to the construction industry, including civil engineering and building construction. Background Art

[0002] In the construction of concrete walls, a structure needs to be installed that holds the concrete inside during wall pouring (i.e., when pouring fresh concrete) until the concrete reaches a consistency that allows it to hold its own shape.

[0003] The formwork of the wall consists of two opposite faces with the concrete located between the opposite faces. Therefore, using the systems known in the prior art, it is necessary to approach both sides of the wall to position the elements that make up the formwork. If the wall is relatively high, auxiliary means are required to approach both sides of the wall in order to reach the positioning positions of the elements that make up the formwork.

[0004] The formwork generally consists of a threaded rod supporting an end nut and a support, such that a plate of the formwork that will contact the concrete is provided between the end nut and the support, and once the wall pouring is completed, the support is subsequently embedded in the wall.

[0005] In terms of reducing the cost of wall construction, one approach is to approach the wall from only one side of the wall, thus avoiding the use of auxiliary structures on both sides of the wall, thereby reducing construction time as well as costs related to the structure and time.

[0006] Known similar devices employ different connection systems between their elements, but do not provide a secure and simple tight connection between the elements and the formwork plate like the subject device of the present invention, such as the device disclosed in EP3553253B1.

[0063] The present invention aims to provide a device for positioning a mold plate used in the construction of a concrete wall. The device helps to position the above-mentioned mold plate from the same side of the wall, thus avoiding the need to approach the wall from both sides.

[0064] The device for positioning a mold plate used in the construction of a concrete wall according to the present invention includes a threaded rod (1) with a flat side. The threaded rod (1) is commercially known as a rod.

[0065] The device for positioning a mold plate used in the construction of a concrete wall surrounds the threaded rod (1). The device includes:

[0066] - A first flat plate (3) for supporting the mold plate (100);

[0067] - Blind nut (4), said blind nut having a blind threaded housing (5), said blind threaded housing configured to receive one end of a threaded rod (1) such that the threaded rod (1) cannot pass through the blind threaded housing (5) at the end opposite the entry end;

[0068] - First spacer (6), said first spacer including a cylinder (7), a first end of said first spacer configured to abut against a first flat plate (3) in which the threaded rod (1) is located, a second end of the first spacer including a first stop (8), said first stop having a lip (9) of elastic material, said lip making the second end frustoconical;

[0069] - Cylindrical central body (10), which is symmetrical and includes bushings (11) at each end; the bushings (11) are frustoconical in shape; such that the bushings (11) are configured to be inserted into the first stop (8) at the second end of the first spacer (6), and a seal is formed due to the complementary shapes of the elastic material lip (9) with both the first stop (8) and the bushing (11);

[0070] - Second spacer (12), said second spacer including a cylinder (13), a first end of said second spacer including a second stop (14), said second stop having a lip (15) of elastic material, said lip of elastic material making the first end frustoconical to receive the bushing (11) of the cylindrical central body (10) and form a seal; a second end of the second spacer is configured to abut against a front plate (16);

[0071] - Front plate (16), said front plate configured such that the threaded rod (1) passes through a threaded central hole (17); in addition, in addition to said threaded central hole (17), the front plate (16) further includes a second flat plate (18) to support a second mold plate (101); and

[0072] - Tightening nut (19), which is configured to be threadedly connected to the threaded rod (1) and contact the front plate (16) and hold the front plate in place, the tightening nut being supported by a handle (20), said handle configured to assist in the positioning and fixing of the tightening nut (19).

[0073] The first flat plate (3) of the device for positioning a mold plate for concrete wall construction includes a first retaining screw (24), said first retaining screw configured to be threadedly connected to the first flat plate (3) and ensure the dimensions of the mold plate (100).

[0074] The front plate (16) of the device for positioning a mold plate for concrete wall construction includes a second retaining screw (25), said second retaining screw configured to be threadedly connected to the second flat plate (18) and ensure the dimensions of the mold plate (100).

[0075] In the first flat plate (3) of the device according to the present invention, there is a bearing surface (26) between the first flat plate (3) and the blind nut (4), and the bearing surface (26) has a convex shape, so that the support of the blind nut (4) on the first flat plate (3) is always comprehensive, thereby absorbing any possible irregularities of the components of the device.

[0076] In the device according to the present invention, there is a bearing surface (27) between the second flat plate (18) and the fastening nut (19), and the bearing surface (27) is a convex surface, so that the support of the fastening nut (19) on the second flat plate (18) is always comprehensive, thereby absorbing any possible irregularities of the components of the device.

[0077] Both the first spacer (6) and the second spacer (12) pass through the die plates (100, 101), and their lengths are equal to the width of the die plates (100, 101).

[0078] The die plates (100, 101) include a die surface (21) and a die surface support frame (22), so that the die surface (21) faces the cylindrical central body (10), and the cylindrical central body is embedded in the concrete when the wall pouring is completed. In a preferred embodiment of the present invention, the die surface (21) is made of a phenolic board.

[0079] The handle (20) is a component including a central hole (28), and the central hole has a section with two parallel planes (29) and two opposite curved surfaces (30), so that the section is configured to limit the position of the handle (20) on the threaded rod (1), because by matching the parallel planes (29) with the flat sides of the threaded rod (1), the handle (20) can move on the threaded rod (1), and by rotating the handle (20), the position of the handle can be limited to a certain point on the threaded rod (1).

[0080] The fastening nut (19) includes two polygonal protrusions (31), so that the handle (20) includes two recesses (32) complementary to the polygonal shape of the protrusions (31), so that the handle (20) is fixed to the fastening nut (19), thereby preventing relative movement between the handle (20) and the fastening nut (19), and thus fixing the position of the fastening nut (19) on the threaded rod (1).

[0081] In an embodiment of the present invention, the cylindrical central body (10) of the device for positioning the die plate for concrete wall construction is made of PVC and passes through the phenolic board through the hole (23) on the phenolic board, so that the elastic material lip (9) is responsible for plugging the hole (23) of the phenolic board through which the threaded rod (1) passes, thereby forming a seal.

[0082] In a preferred embodiment of the present invention, the elastic material lip (9) of the spacer (6, 12) is made of an elastic polymer.

[0083] The bushing (11) of the device according to the invention is configured to be removable from the cylindrical central body (10), so that once the wall has been cast, the bushing can be removed from the cylindrical central body (10) and only the aforementioned cylindrical central body (10) remains in the concrete.

[0084] When the formwork (100, 101) is positioned and fixed in its casting position, the device for positioning the formwork for the construction of a concrete wall according to the invention simultaneously produces two effects: it ensures the width of the wall (25 cm, 35 cm or 40 cm), and it ensures the tightness of the internal joints of the wall by means of elastic elements.
