ANCHORING AND ATTACHMENT ASSEMBLY FOR MODULAR CONSTRUCTIONS

Abstract

An anchoring and attachment assembly is for modular constructions. The assembly allows anchoring factory-built modules to the foundation of a building, as well as attaching the modules forming the building, thereby acquiring high strength and robustness of the modular construction. The assembly includes a support, and may also include an interconnection. Both the support and the interconnection include projections outwardly projected in a perpendicular plane with respect to the respective metal plates. The projections define a closed and hollow enclosure, and are dimensionally adapted for insertion into a modular post.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] Several preferred embodiments that refer to the aforementioned drawings are described below, without this limiting or reducing the scope of protection of the present invention.

[0024] According to a first preferred embodiment shown in FIGS. 1 and 2 focusing on a modular structure of single posts (P), the anchoring and attachment assembly comprises: [0025] a support (10) in turn comprising a first metal plate (11) and at least one hollow metal projection (12), where on one hand said support (10) can be coupled to an upper and/or lower end of a modular post (P), and on the other hand it can be coupled to the floor of a modular construction; [0026] an interconnection (20), comprising a second metal plate (21) located in the intermediate position between at least one pair of projections (22) located on one and the same vertical plane and in a symmetrical position with respect to said second metal plate (21); and [0027] screws (30, 40) for fixing the support (10) and the interconnection (20) with the modular posts (P), as well as with the floor and/or roof of the modular construction in question.

[0028] However, according to a second preferred embodiment shown in FIG. 4, it has been provided that the support (10) is configured for a double modular post (P), having two projections (12) to that end. Similarly, for this second embodiment focusing on double posts, it has been contemplated that the interconnection (20) may have two pairs of projections (22) attached to one and the same second metal plate (21). Therefore, although FIGS. 2-4 depict only those cases for single and double posts (P), it should be indicated that the anchoring and attachment assembly of the invention can likewise be adapted to factory-built modules with three, four or more posts, without this changing the spirit or essence of the invention.

[0029] In FIGS. 2 and 4, it can be seen that the projections (12, 22) of both the support (10) and the interconnection (20) are outwardly projected in a plane perpendicular to that of the metal plates (11, 21) and define a closed and hollow enclosure dimensionally adapted for the insertion thereof into a modular post (P). It can clearly be deduced from FIG. 3 that the dimensions of the projections (12, 22) are respectively smaller than the perimetral dimensions of the posts (P) for the purpose of allowing the coupling between both elements.

[0030] Furthermore, it can be seen in said FIGS. 2 and 4 that the projections (12, 22) of both the support (10) and the interconnection (20) have through holes (13a, 23) located in two of their facing side walls, in which transverse screws (30) are insertable. Preferably, as shown in FIG. 2, these transverse screws (30) comprise a bolt (31) with a welded washer constituting the head of the bolt (31), an auxiliary washer (32) and a pin (33), such that said bolt (31) has a through hole in the proximity of its distal end, in which the pin (33) is insertable. At this point it should be indicated and emphasized that the particular configuration of the washer of the head of the bolt (31) and of the auxiliary washer (32), which have a non-circular, elongated and flattened geometry in the form of an oval flange. This feature is neither trivial nor random, but rather has two well-identified objectives:

[0031] a) to constitute grips facilitating the mounting work for operators; and

[0032] b) to achieve a solution that does not run into or impact the metal plates (11, 21), because in that case the bolts (31) could not be introduced in their entirety into the corresponding through holes (13a, 23).

[0033] On the other hand, it can also be seen in FIGS. 2 and 4 that the metal plate (11) of the support (10) has through holes (13b) in which longitudinal screws (40) are insertable for the fixing and anchoring thereof to the floor of a modular construction, and which in this embodiment comprise corrugated anchor bolts (41) adapted for concrete, nuts and washers, shown in FIGS. 2 and 3.

[0034] In relation to the preceding, FIGS. 2 and 3 show that the metal plate (11) of the support (10) has length and/or width dimensions exceeding those of the metal plate (21) of the interconnection (20). This is primarily for two reasons:

[0035] c) The first of such reasons is to create a region for implementing those through holes (13b) of the metal plates (21) mentioned above;

[0036] d) The second of such reasons is to constitute a sufficient support and contact surface on the floor of the modular construction in question.

[0037] At this point it should be pointed out that even though the support (10) and the interconnection (20) in the embodiments of FIGS. 2 to 4 have quadrangular shapes or square bar shapes, it has nevertheless been provided that said elements can have circular shapes in both the metal plates (11, 21) and in their projections (12, 22), this case being applicable to cylindrical posts having an obviously circular section.

[0038] With respect to the attachment between the projections (12, 22) and the metal plates (11, 21), said attachment is preferably by welding, and more specifically welding along the inner faces of the projections (12,22). This particularity allows assuring the stiffness and strength of the entire assembly, while at the same time avoiding problems during the process of mounting and coupling with the modular posts (P). In fact, any type of inclination, mismatching or allowance as a result of the contact or interference between posts (P) and the ribs or surfaces resulting from the welding is thereby achieved.
