Abstract

Three-dimensional covering block has metal frame truss, those are connected with links arranged as additional upper belt, with installation between the upper belts of the frame truss and connection by means of angle brace of three-dimensional grate to the nodes of the lower belts, and with thrust elements connecting the nodes of angle brace elements of the lower belts of the frame truss. The bearing three-dimensional element, that is a welded structure, is made of metal rods, as a regular prism, with the ribs normal to the base and the side vertical faces being provided with diagonals connected in the nodes of the upper and the lower belt in sequence; the prism is supported with inner diagonal connecting the lower belt of two diagonals of side faces coming to each other to the upper belt. The rods, that are connected together in the nodes, are a three-dimensional element, and connect the elements along vertical ribs in such a way that the lower node of the inner diagonal of the element coincides with the lower node of the inner diagonal of the following element, and the upper node of the inner diagonal coincides with the upper node of the other element and so on. Space between the elements is supported by inner diagonal.

Description

Description of the invention

The invention relates to the field of construction and can be used as load-bearing structures and covering of 2 one-story industrial buildings and constructions and other run-of-the-mill buildings.

A spatial rod covering is known, which includes flooring, long-dimensional upper and lower belts - an invention described by A.S. 488899 IPC EO4S3/08. Spatial block covering, which contains metal rafter trusses connected by ties with upper and lower belts connected to them at nodes by lattice elements with braces and risers - an invention described by A.S. 535401, IPC E04S3/08.

The closest analogue of the proposed invention, chosen as a prototype, is the invention described in A.S. 642445, IPC E04S3/08.

The spatial block of the covering contains metal rafter trusses, united by metal ties, made in the form of an additional upper belt located between the upper belts of the rafter trusses and connected by means of braces of spatial lattices to the nodes of their lower belts, and spacers connecting bracing nodes of 72 lower belts of rafter trusses.

Known designs increase the number of ribs (rafter trusses and additional connections), which leads to weighting of the block and overspending of materials.

The invention is based on the task of reducing metal consumption, reducing installation time, and increasing the stability of the structure.

The task is solved by the fact that the spatial block of the covering includes a supporting spatial element, which is a welded structure made of metal rods in the form of a regular prism, the edges of which are perpendicular to the base, the side vertical faces are equipped with diagonals, which are connected in the corners of the upper and lower belts - consecutively. The prism is reinforced by an internal diagonal that connects the lower belt, where the two diagonals of the side faces meet, with the upper belt. Jointly connected rigidly at the nodes, rods c 22 represent a spatial element. During assembly, connect the elements (by means of a dark chessboard) along the vertical edges so that the lower node of the internal diagonal of the element coincides with the lower node of the internal diagonal of the next element and the upper node of the internal diagonal of the element coincides with the upper node of another element, and so on . The inter-element space (light checkerboard) is successively supplemented with the same internal diagonal. In this way, the load-bearing spatial block of the coating is assembled. M

The proposed spatial element, assembled into a spatial block of the covering, provides: Ге) - minimal labor intensive manufacturing; - reduction of metal density; o - interchangeability of elements; c - reduction of the time of construction of the spatial block of the covering;

The essence of the proposed invention is explained by the drawings, which show the proposed space-bearing element - (Fig. 1) and the spatial covering block composed of separate elements - (Fig. 2). The supporting spatial element has the shape of a regular prism. The edges (1) of the prism are perpendicular to the base.

The lateral vertical faces are equipped with diagonals (2), which are connected in the corners of the upper and lower belts "in series. The prism (Fig. 1) is supported by an internal diagonal (3), which connects the lower belt, where the two Z diagonals of the side faces meet, with the upper belt. Jointly connected rigidly at the nodes, the rods represent a spatial element (Fig. 1). z" When assembling, connecting elements (by means of a dark chessboard) along vertical edges so that the lower node of the internal diagonal of the element coincides with the lower node of the internal diagonal of the next element, and the upper node of the internal diagonal of the element coincides with the upper node of another element, and so further, and reinforcing the inter-element space (light checkerboard) with the inner diagonal (3), we assemble the load-bearing i-th spatial block of the covering (Fig. 2). o The supporting spatial element works as follows:

Thanks to this arrangement of the rods, there is a rational distribution of forces. The own weight in the bearing of the spatial element is perceived by the bearing rods, they work for compression or tension. In b 20 spatial elements working on rotation, such a direction of inclined rods is important, since the forces in the belts depend on it, on rotation. This will always be the case if the adjacent planes are inclined

T" rods will be directed so that for a given panel of the belt in both planes the moment points will be in the same direction and, at the same time, from the torque in the inclined rods, there will be an alternation of signs of forces: if one is compressed, then the next one is stretched. as (F) 8 C bo se dd- 65 Figi
