Abstract

This is a guardrail (10) of the type installed for fall protection in residential and commercial environments; said guardrail (10) is formed by a modular assembly (CM) configured by multiple solid structural profiles (11) whose upper edges develop into extensions (llal)/(llbl) in a rotated 'L' shape projecting from the outer face of the side walls (lla)/(llb) and the central portions develop into oblique appendages (Ila2)/(llb2); the intermediate portion of both walls (1 la)/( 11b) of the profile (11) has oblong projections (lld) on the outer faces; from the lower extreme edges of the profile (11) develop 'L' shaped members (lie); the finishing caps (12) have a supplementary engagement tooth (12c) projecting parallel to the flange (12a); each wall (lla)/(llb) of the structural profile (11) receives respective sealing rubbers (15A)/(15B) ordinarily parallelepiped.

Description

TECHNICAL FIELD [001] This utility model relates to an arrangement introduced in a guardrail of the type installed for fall protection in residential and commercial environments where, notably, it presents innovative constructive characteristics considering that it is formed by a modular assembly comprising multiple and identical structural profiles provided with a coupling for attaching a finishing cap, as well as having locations for receiving sealing rubbers that neutralize the effects of expansion and vibration of the structure, contributing to the locking of the cap and configuring a sealing region that prevents the passage of water and dirt to the core of the structural profiles and, thus, preserving the useful life of the wedge and backrest/channel stored in the internal region of the profile. HISTORY OF THE TECHNIQUE [002] It is known that guardrails are structures that play a crucial role in the safety of residential and commercial buildings, as they are designed to provide support and protection for passersby, especially in areas with a risk of falling from a height, such as stairs, balconies, terraces, verandas and other locations. [003] In the market, there is a wide variety of guardrail types, one of which features a base profile with a U-shaped cross-section designed to be screwed into the masonry, and also serves as a support for the laminated glass panel, which rests on an L-shaped backrest or channel. One of the profile walls has an internal cradle designed for mounting a sealing gasket, while the opposite side has an arrangement of wedges that help stabilize the panel. In addition, a finishing profile is applied to the upper end of the laminated panel. [004] The aforementioned guardrail model presents an installation challenge due to its elongated profile, especially during the soil drilling process for fixing, considering that potential obstacles such as surface deformations, steel meshes present in the internal structure of the masonry, or other elements may hinder installation. On the other hand, a sectioned profile offers more installation flexibility, since it allows for the choice of fixing points. [005] A sectional profile model is presented in document no. BR 20.2018.070303-5 which provides a set of supports and locking system for glass and self-supporting guardrail panels consisting of an aluminum profile configured in a "U" shape that is applied along the entire linear length of the guardrail from joints with metal pins of the dowel type, fitted into the holes provided in the aluminum profile, ensuring locking and alignment at each joint, and can also be mounted in an interrupted manner in equidistant segments, and which after being fixed to the masonry, receives plastic components in the shape of "L" plastic corner pieces and a wedge-shaped corner piece that provides locking to the assembly of the profile and the glass or panel. [006] Although the aforementioned document presents the profiles sectioned into individual modules that contribute to the positioning during installation, they depend on the use of metal dowel-type pins that pass through the holes provided in the profiles in order to ensure firmness in the structure and alignment. [007] Another aspect to be observed is the method of fastening the finishing caps used to cover the sides of the profiles. These caps only integrate top engagement hooks, leaving the lower ends free of attachment. This results in a fragile fastening that can lead to the finishing caps becoming unattached in case of bumps or similar interference. [008] Furthermore, the guardrail presented in document no. BR 20.2018.070303-5 uses plastic sealing parts attached to the profiles, a material considered fragile in relation to impact and quality tests, which may compromise the effectiveness of the seal and the durability of the system as a whole. State of the Art Analysis [009] Research conducted in specialized databases revealed documents related to guardrails for residential and commercial construction, such as the one presented in document no. BR 20.2020.022995-3, which deals with a set of elements used in the assembly and fixing of glass panels, such as guardrails for staircases, balconies, and others. It comprises a first element: a base with a lateral profile in the shape of the letter 'L', featuring a horizontal lower wall and a tapered vertical wall, assuming a wedge shape, and having a central rectangular opening inside which a plurality of horizontal and parallel appendages are formed, whose front edges have tooth-like formations. It also comprises a second element: an upper wedge, which comprises a vertical plate that tapers from its upper end to its lower end, resulting in a wedge shape. The aforementioned wedge features a recessed, vertical central region, in which a serrated surface is formed, with multiple teeth of triangular profile arranged horizontally. [010] Document no. BR 10.2017.006877-3 presents a structure in extruded aluminum p
