Abstract
Description
Technical Field
[0001] This invention relates to a plastic separator, and more specifically to a plastic separator specially designed to ensure the correct positioning of the steel frame or wire mesh during the laying and concrete pouring process of expanded polystyrene sandwich panels with wire mesh.
[0002] Therefore, the object of the present invention is to provide a device for preventing the movement of a metal mesh during concrete pouring, whether in the production of floor slabs or vertical panels, so that the mesh can be embedded in the concrete. Background Technology
[0003] Within the practical application scope of this invention, when producing reinforced concrete sandwich panels insulated with polystyrene, a wire mesh is laid between the polystyrene panel and the template, and concrete is poured onto the mesh to reinforce the layer.
[0004] The problem is that the net often moves during this process, which may cause the net to fail to be perfectly centered in its intended position.
[0005] In an attempt to avoid this problem, some separator elements are known to be nailed to the polystyrene panel itself, but this can cause damage to the panel. Summary of the Invention
[0006] The separator recommended in this paper is based on a simple yet effective solution that addresses the aforementioned problems in a completely satisfactory manner.
[0007] Therefore, the device of the present invention consists of two parts that are fixed together by clamping on the steel frame itself, the parts having different openings on all sides to allow micro-concrete to enter and fix the wire mesh during the concrete pouring stage.
[0008] The portion described is made of injection-molded ABS plastic. Acrylonitrile-butadiene-styrene (ABS) is an amorphous polymer formed by emulsion or bulk polymerization of acrylonitrile and styrene in the presence of polybutadiene. The most important properties of ABS are impact resistance and hardness.
[0009] More specifically, the first part has a configuration including a flat, thin-layer body with holes for the passage of micro-concrete, and a peripheral outer shell extending vertically from the body, the outer shell also having windows for the passage of micro-concrete.
[0010] Thus, at the peripheral edge corresponding to the opening of the outer shell, grooves are provided at pairs of opposite and perpendicular points, the grooves defining seats for the rods involved in the wire mesh, the rods being inserted into the grooves until they are perfectly stabilized.
[0011] As previously described, after the first part is installed into the wire mesh, the second part is fixed in the area where the two vertical rods meet by clamping it onto the first part; the second part has an elastic flange for fixing to the window opening of the first part, and a recess for the passage of micro-concrete, and also has an equally open rear neck, the length of which determines the degree of separation between the wire mesh and the template.
[0012] This results in a device that is easy to install on the wire mesh itself without damaging the expanded polystyrene panel, and that is durable and ensures perfect positioning of the wire mesh during concrete pouring. Attached Figure Description
[0013] To supplement the description herein and to aid in a clearer understanding of the features of the invention, this specification is accompanied by a set of drawings that form part of the invention, illustrating, rather than limiting, the following:
[0014] Figure 1 shows a perspective view of a steel wire mesh partition for building manufactured according to the present invention, showing the device without the application of a steel frame.
[0015] Figure 2 shows a perspective view of the device from another direction in the previous figure.
[0016] Figure 3 shows a perspective view of the first part involved in the separator coupled to a wire mesh or steel frame.
[0017] Figure 4 shows a perspective view of the second part, which is designed to be mounted on the component shown in Figure 3 by a simple clamping method. Detailed Implementation
[0018] As can be seen from the accompanying drawings, the separator of the present invention consists of two parts, namely a first part (1) and a second part (2), which are fixed together by clamping, and a pair of mutually perpendicular rods of a steel frame or wire mesh (3) are stably clamped between the parts.
[0019] More specifically, the first part (1) is composed of a flat thin body (4), which in the selected embodiment has a circular configuration, although it may also have other configurations such as polygons without affecting the nature of the invention; the thin body has a plurality of holes (5-5') for micro-concrete to pass through.
[0020] A peripheral shell or skirt (6) with a window (7) extends vertically from the thin body, the window also allowing micro-concrete to pass through, and thus defining the means for fixing to the second part, which will be detailed later.
[0021] Four pairs of opposite and perpendicular grooves (8-8') are provided at the free edge corresponding to the peripheral skirt (6), the grooves being designed to receive the rods involved in the wire mesh (3); since the rods are arranged in different parallel planes due to their own thickness, the grooves (8') have a greater depth than the grooves (8).
[0022] Thus, as shown in Figure 3, the first part is coupled to the corresponding area where the two vertical rods in the wire mesh (3) meet through the groove (8-8'), and once this operation is completed, the second part (2) is coupled from the opposite side by clamping on the first part (1).
[0023] For this purpose, the second part (2) has a flat base (9) with radial window openings (10) so that micro-concrete can pass through it;
[0024] The side facing the first part (1) terminates at a locking ring (11) designed to lock the groove (8-8'), the locking ring having a toothed flange (12) that can clamp the window (7) of the first part (1) and achieve locking, as clearly seen in the details of FIG1.
[0025] Finally, the flat base (9) of the second part (2) terminates at the hollow tubular neck (13), which determines the degree of separation between the template and the wire mesh (3).
