Description

I

The invention relates to construction and to be used in the construction of industrial, civil and agricultural coatings. Natural buildings and structures.

Known designs of vaulted coatings of various materials with lattices made in the form of separate rods, anchored in the supporting nodes of the vaults. Thus, for example, there is a known panel in which the roof is full, of two of the plates connected by tightening and pivotally interconnected, each of which is made with ribs of a curvilinear outline J.

The disadvantage of these coatings is that the open metal cap is subject to corrosion and is not fire resistant enough. In addition, the point application of the puff to the arch supports necessitates their additional reinforcement in order to redistribute thrust forces.

Closest to the present invention, there is a tafed-up arched structure for a span of the KZH type, in which the arched plate is monolithically connected to the segment ribs with a wider lower part. These ribs perform the role of tightening and prestressed rod reinforcement is located in the lower broadened parts and its anchoring is provided by special anchoring devices 7. J.

A disadvantage of the known construction is that the segment ribs create unventilated and poorly used spaces, there is no possibility to perform the ceiling, and, moreover, the point application of the embossing creates certain difficulties in ensuring the reliability of their anchoring.

The purpose of the invention is to increase the reliability and improve the operational qualities of the structure, install a suspended ceiling, and provide ventilation of the space above the ceiling. The goal is achieved by the fact that the covering panel, including the upper vaulted element and tugging, interconnected by bonds, is made in the form of a flat plate, the width of which corresponds to the width of the vaulted element. The Yarici flat plate is provided with a protrusion for supporting the vaulted plate. The present construction of the coating for spurs consists of an upper vaulted element and a flat prestressed reinforced concrete fastener associated with it. The distribution of the thrust force along the entire support part of the panel increases the reliability of the design due to the lower probability of failure of the anchor nodes and, in addition, simplifies their design. The presence of a flat fastener allows, in the necessary cases, to provide ventilation of the space under the coating, to create conditions for the use of this space, for example, for arranging various communications. And, in addition, to create a flat ceiling design. can be made with perforations for better sound performance. scheni The insulation in the panel can be made along a flat tightening or along an upper vaulted element. In the latter case, the upper vaulted element of the panel is better to be made with cement-free ruberoid. Figs 1 and 2 show the variants of the coating panel, a general view: Fig 3, a detail of the reference node: on. Fig. 4 is a section A-A in Fig. 3; The coating panel includes a flat-plate-tack 1 made of prestressed reinforced concrete, for example, reinforced cement, with a thickness of 20-30 mm with wire reinforcement, the upper vaulted element 2, also made of prestressed concrete of the same thickness and vertical links 3, which can be placed - across the panel (fig. or along it (FIG. 2)). Vertical links are made of mostly lightweight concrete, and are attached to and saoda by welding the inserts or by any suitable method, For example, by gluing, if it is necessary to ventilate the space under the vaulted element, vertical connections should be preferred (Fig.). The geometric dimensions of the vertical connections determine the outline of the vaulted element and are chosen so that the vault arrow is within the limits of -d - up to -4-from pr20 f 6 ta. The vaulted element 2 is made flat and during the assembly of the panel it is given a vaulted shape with the help of a traverse, which secures the element in the middle third of the span. The assembly can be carried out at the factory or on the construction site. In the latter case, the transport of the panel elements is carried out in a flat form. The joining of the vaulted element with a flat tightening in the bearing part can be achieved by welding the fixings or in any other way. An example of the design of the reference node is shown in FIG. The prestressed wire reinforcement 4 of the flat tightening 1 is passed through holes in the anchor plates 5 interconnected by additional metallic connections 6, the length of which is chosen from the condition of proper anchoring. The stop 7 is made of a bent profile and is positioned in such a way as to transfer the thrust force to the anchor plate 5. The end of the vaulted element 2 is welded at separate points to the stop 7, the use of a vaulted panel will increase the reliability of the structure by dispersing the efforts of the thrust over the length of the support part. : the design of anchor devices will be simplified by reducing the specific effort on the support, saving energy for heating due to the creation of minimum space, Kpotfe, possibly creating a technical attic with different location of communications and ventilation, as well as improved use of vehicles in the case of transportation of items in a flat state. Claims An overlaid coating panel comprising a vaulted slab and a stopper, connected by connections.
