SU1252463A1 - Skeleton of industrial building with suspended roof - Google Patents

Description

The invention relates to the construction of multi-lot industrial buildings with overhead crane equipment and can be used for public buildings in the presence of local temporary loads on the floor and with a large column spacing in the longitudinal direction.

The purpose of the invention is to reduce the material intensity of the frame with an increased column spacing and simplify installation.

FIG. Figure 1 shows the skeleton of a production building with a coating; FIG. 2 is a stretched element of the hang of the coating J in FIG. 3 shows section A-A in FIG. 2; in fig. A is the junction junction into a cross system i in FIG. 5 - node 1 on

FIG. one.

The frame 1 of the production building with a coating of 2 includes columns 3 and girders 4 forming frames 5, a system of supporting cross elements 6 supported on columns 3, stiffening beams 7 arranged perpendicular to frames 5 and attached to supporting cross elements 6 in nodes of their intersection by means of suspensions 8, and straps 9, anchored in foundations 10.

Bearing cross-elements 6 are made in the form of rods 11 of a bent profile with flat limb 12 at the ends. The bends 12 are provided with cone-shaped stops 13, directed in opposite directions, made with holes 1A and interconnected at the intersection nodes by means of bolts 15, passed through holes 14. The frame is equipped with deadbolts 16, placed on the plane of the frames 5, and stiffening beams 17, mounted parallel to frames 5 and freely supported on girders 4, Zalki 7 and 17 of rigidity attached to the middle of the span to the supporting cross elements 6 rigidly.

Bearing cross-elements 6 are rigid bending.

Crossbars 16 can be replaced with trusses; Beams 17 of rigidity are supported with ends on bolts 16 or lower ones. Stiffening beams 7 are used as paths of overhead cranes 18,

To isolate the columns 3 from the impact of the spreading of the strands on them, all the bolts 4 are horizontally supportive on the columns 3 with the transfer of the strands to the ends of the bolts 4 in adjacent spaces and then to the side straps 19 5 in the level of the transoms 4,

Bearing cross-elements 6 are cold-formed thin-sheet channel bars, conical hollow stops 13, at the ends of which, stops are made at the nodes of the cross system to form shear-resistant connections.

20

When loading the cover 2 with a temporary local concentrated load from the overhead cranes 18, the force at the loaded point of the cross system is redistributed to the entire cover 2, and due to the use of stretched elements in the form of rolled bars 11 instead of cables of the deformation of the coating 2, and therefore bending moments in stiffeners are reduced in proportion to the elastic modulus of the materials mentioned, which leads to a decrease in the material intensity of the coating,

in multi-span production buildings, when one of the flights is loaded with a temporary load applied to the orthogonal system of beams 7 and 17, the thrust occurring in elements 6 is transmitted through the rigid node 20 to crossbars 4 to neighboring unloaded spans and further

through the side braces 19 to the anchor foundation.
