SU553338A1 - Metal Spatial Coating Unit - Google Patents

Description

one

The invention relates to metal structures of coatings adapted for conveyor assembly and large-block installation, and can be used in the construction of single-storey industrial buildings with a light roof (mainly using metal profiled flooring).

A spatial covering unit is known, including a flooring, long-sized upper and lower tracks, and a system of diagonals, in which the upper tracks are made of a profile that is rigid in a vertical plane and fixed in a horizontal plane by a flooring f 1 attached to it.

The disadvantages of this solution are the many hours of operation and the high metal consumption associated with the unfavorable load transfer to the supports through a large number of lattice elements located in inclined planes.

Also known is the spatial block of the coating, assembled from flat and linear elements (roof trusses, subrafter beams, girders, flooring, etc.) in which the girders are arranged parallel to the roof trusses and are supported on cantilever lampposts made in the form of small-height trusses and on substrip beams.

The disadvantages of this solution are increased

metal consumption, complicated construction of lamppost panels, impossibility of using this construction in besponarny blocks.

The closest technical solution to the invention is a metallic spatial block of the coating, including the roof trusses, which are parallel to them by themselves, and the flooring.

The disadvantages of this solution are the increased metal consumption and the multi-site design, which is associated with the use of auxiliary lattice elements — vertical links supporting the purlins and

performed with knots on the clamps.

The aim of the invention is to facilitate the unit and simplify its installation.

This is achieved by the fact that the runs are installed on the struts, the lower ends of which

Founded on sastroplnyh farms.

In addition, each of the struts can be made in the form of a tubular element with flattened ends. FIG. 1 depicts the spineless unit

floor coverings; in fig. 2 - lantern unit at the level nastnla the lamp; in fig. 3 is a section along A-A in FIG. one; in fig. 4 is a section along BB in FIG. one; in fig. 5 is a section along BB in FIG. 2; FIG. 6 - section

according to YY in FIG. 2; in fig. 7 is an example of an upper junction assembly of the tubular strut to the outermost run (node I); in fig. 8 is a section along d-d in FIG. 7; on phpg. 9 - the primer of making the lower joint of the braces to the truss (node II), the truss elements and the spacer are not conventionally shown ;.

The metal spatial block of the coating contains roof trusses 1 connected to subrafter trusses 2; in the lantern blocks, truss trusses 3 and side lanterns 4 are installed on the truss trusses 1; parallel to the upper truss and lantern trusses 1 and 3 on the strut 5, intermediate runs 6 and extreme runs 7 are installed. At their ends, the ridges 6 and 7 are supported on truss trusses 2 and on the side panels of the lantern 4. The lower ends of the strut 5 farm 1 in their nodes. These nodes are interconnected by struts 8. Roofing 6 and 7, as well as the upper sections of the safarm 1 and 3, are laid and the roofing floor 9 is attached to them. In necessary cases, the construction of the block contains horizontal connections (not shown in the diagrams) .

The struts 5 can be taken out of the pipes with flattened ends, and the nodes of roof trusses 1 and the girders 6 and 7 - with vertical walls and protruding horizontal shelves. The connection of the struts 5 with the trusses 1 and the purlins 6 and 7 is carried out by supporting the end of the strut into the corner formed by the wall and the flange of the purlin or the truss assembly.

The peculiarity of the static operation of the block is that the vertical load, perceived by girders 6 and 7, is transmitted to the trusses 1 nodes through transverse struts 5; the horizontal components of the efforts in the lower nodes of the joining of the braces to the trusses are for the most part mutually extinguished, as a result of which the struts 8 are, as a rule, lightly loaded; horizontal force components in the upper nodes of the junction of knots

to the extreme irogons 7, in an isolated block, perceives flooring 9, working on stretching. The possibility of such work is provided by the horizontal rigidity of the extreme

runs and attaching the flooring to the girders and farms. After interconnection of the extreme runs of adjacent blocks, the flooring is turned off from work and the indicated longitudinal forces.

The struts and struts contained in the block construction practically form a system of vertical tie trusses; The lack of special upper pillars of these trusses (the role of which is played by the flooring) and the performance of their elements from pipes with direct (without facing) connections at the nodes ensures a reduction in the number and mass of the parts forming the structure, as well as a reduction in the amount of machining, assembly and welding design elements.
