SINGLE-LAYER REINFORCED CONCRETE PANEL

Abstract

A single-layer reinforced concrete panel in the field of construction can be used in the construction of multilayer outer walls of residential, public and industrial buildings. The effect is achieved by the fact that a single-layer reinforced concrete panel for mounting a hinged facade, reinforced with a mesh, is equipped with embedded parts in the form of plastic sleeves of a cone-shaped shape, formed at the intersection of the longitudinal and transverse rods of the reinforced mesh, for fastening fasteners and driven dowels, and the location of the plastic sleeves corresponds to the location of the hinged facade brackets attached to the plastic sleeves with fasteners, and the location of the driven dowels for fixing the insulation. The use of the panel increases the pull-out force and the reliability of fastening the hinged facade bracket and insulation.

Claims

1. A single-layer reinforced concrete panel for the installation of a suspended facade, reinforced with a mesh, characterized in that it is equipped with embedded parts in the form of plastic cone-shaped sleeves/endings formed at the intersection of the longitudinal and transverse rods of the reinforced mesh, for fastening fasteners and driven fasteners, and the location of the plastic sleeves/endings corresponds to the location of the hinged facade brackets attached to the plastic sleeves with fasteners, and the location of the driven dowels for fixing the insulation.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0020] FIG. 1 design of a single-layer reinforced concrete panel with embedded plastic endings.

[0021] FIG. 2 mesh with embedded plastic endings.

[0022] FIG. 3 single-layer reinforced concrete panel in section.

DESCRIPTION OF EMBODIMENTS

[0023] FIG. 1 shows the design of a single-layer reinforced concrete panel 1 for large-panel housing construction, reinforced mesh 2, made of longitudinal and transverse rods (3 and 4, respectively) of metal and/or composite reinforcement (fiberglass, basalt).

[0024] On FIG. 2 at the intersections of the longitudinal and transverse rods 3 and 4 of mesh 2, plastic sleeves are formed with an internal hole: for fastening fasteners (screws, self-tapping screws, screws, anchors and dowels).

[0025] The shape and dimensions of plastic endings depend on the type of fasteners used. Depending on the type, plastic sleeves for fasteners can be divided into screw-in 5 (fastening of curtain wall brackets) and driven-in 6 (insulation fastening). An example of attaching a hinged facade bracket 7 to a single-layer reinforced concrete panel reinforced with a mesh with plastic sleeves 5 (in section) is shown in FIG. 3.

[0026] Plastic sleeves 5 and 6 are molded in such a way that at the exit from the reinforced concrete panel they have a tapering conical shape. This significantly increases the pull-out force, since the shape and location of the sleeves exclude their tearing out of the single-layer reinforced concrete panel, which greatly increases the reliability of the connection.

EXAMPLES

[0027] An example of attaching a hinged facade bracket 7 to a single-layer reinforced concrete panel reinforced with a mesh with plastic sleeves (in section) is shown in FIG. 3. At the same time, plastic sleeves are located at the intersections of the longitudinal and transverse mesh rods and coincide with the attachment points of the hinged facade bracket and insulation. This can be achieved by moving the nodes of intersection of the longitudinal and transverse bars of the grid according to the requirement of the customer.

[0028] Installation of a hinged facade is carried out as follows.

[0029] In accordance with the requirements of the customer, automatic lines (similar to those described in RF U.S. Pat. No. 2,548,358) produce a mesh with plastic sleeves fixed at the intersection of the longitudinal and transverse rods, which are embedded elements.

[0030] The location of plastic endings 5,6 in the attachment points of the longitudinal and transverse mesh rods must correspond to the location of the hinged facade brackets and driven dowels for fixing thermal insulation on a single-layer reinforced concrete panel.

[0031] The mesh is placed in the formwork of a single-layer reinforced concrete panel, orienting it in the formwork so that the plastic endings are located in the right places, while their open end rests against the formwork. Next, the formwork is filled with concrete. After the concrete has cured, the single-layer reinforced concrete panel is transported to the construction site and mounted as a building envelope. After that, the hinged facade brackets are mounted at the locations of the plastic sleeves 5 using fasteners according to their location map and the insulation is fixed with driven dowels.

[0032] On the brackets, guide corner elements and a protective and decorative screen are further placed.

INDUSTRIAL APPLICABILITY

[0033] The proposed design of the reinforced concrete panel significantly simplifies and reduces the cost of mounting a hinged facade by eliminating the need for drilling (drilling) of the panel, incl. on the construction site, and, accordingly, the use of hand tools and manual labor. [0034] At the same time, resources (concrete) are saved by reducing the thickness of a single-layer reinforced concrete panel. improves the reliability of fastening of the hinged facade brackets [0035] Thus, the claimed technical result is achieved: the pull-out force is increased and the reliability of fastening (long-term strength) of the hinged facade bracket and insulation is increased due to the molding of panels with embedded plastic sleeves formed on the grid in the conditions of the production workshop.
