SU949115A1 - Three-dimensional installation unit of span structures of installation roof - Google Patents

Description

The invention relates to the field of construction equipment and can be used as a spatial supporting structure for coatings of large rolling sports and other buildings and structures.

Known spatial mounting block spans, including a system of spatially oriented, rigidly interconnected rods fl.

The disadvantage of this design is the difficulty of installation when overlapping existing structures and placing large equipment between its elements.

The closest in technical essence to the present invention is the well-known spatial mounting block of span structures, including flat through-bearing structures and core links between them in the upper, lower and transverse planar. bone x 2.

The disadvantages of this design are relatively low rigidity, increased quantity; mounting elements for their unfastening and the impossibility of placing large equipment between the elements of the unit.

The purpose of the invention is to increase the rigidity and thereby ensure that the equipment can be placed with the mellada elements of the block.

The goal is achieved by the fact that in the spatial mounting block of span structures

10 structures, including flat through-bearing elements and core links between them in the upper, lower and transverse planes, the bearing elements of the block are made in the form of beams 15 beams, the upper one with each of which is made broken in the form of a double-I-beam, and The shape of an I-beam, whose shelves are located in a vertical plane, at 20 than each beam in the nodes of the bearing is provided with one or several vertical plates with rigid rods attached to the bottom perpendicular to the plates with a support channel with downward slopes olkami

In addition, the upper part of the sailing beam can be equipped with suspension supports for fastening the equipment, and pulling-supports for equipment maintenance grids and elements for fastening the suspended ceiling. FIG. Figure 1 shows a space assembly block of span structures of a building structure in an orthogonal projection, top view; in fig. 2 - the same; side view, with vertical transverse connections; in fig. 3 is a transverse vertical section of the proposed unit; FIG. a fragment of the coating of the proposed constructions in axonometry; in fig. presented in the orthogonal projection, the carrier span structure of the block beam block, in FIG. 6 - the support unit of the beam in the same projection. The spatial assembly block of span structures contains flat end-to-end supporting structures 1, combined in three or more and made in the form of trussed beams with an upper sled 2, an inlet 3 and connecting 3 elements with 2 and 3 and 4 the flat supporting structures are made in the form of a double-sided I-beam, and the puff 3 is made in the form of an I-beam with shelves arranged in a vertical plane. The supporting structure 1 in the nodes of the support is provided with one or several vertical plates 5 with rigidly attached the supporting channel 6 is located below it. The wall of the supporting channel 6 is perpendicular to plate 5, and the shelves of the channel are lowered down. Bearing structure 1 through plate 5 and channel 6 are hinged on rail 7 of subrafter design. 9 and 10J, thus forming a pair of inclined, hardness trusses located in the planes of the upper along sa 2 slopes, which are intersected by a system of parallel vertical stiffness trusses located across the bridge and formed connectors Elements 4 of construction 1, elements of connections 11, connecting ca 2, elements of connections 12, connecting plugs 3, and elements of connection 1 forming the diagonal grid of these trusses. The spatial mounting block of span structures for increasing rigidity can be equipped with an oblique butt element in the form of a vertical plate 5, which is developed over the full width of the block end face. The upper surfaces of the 2 X-ray beams 1 are provided with suspension supports 14 for fastening equipment 15, and the fasteners 3 with supports 16 for fastening the equipment maintenance bridges 17 and supports 18 for fastening under the weight ceiling 19. edlagaemy spatial mounting unit migrating designs of materials used in construction, namely of the roll sheet and section steel members. It is possible to use for these purposes reinforced concrete, aluminum alloys, reinforced plastics or similar materials and their combinations .. To connect the bond elements 9, 10, 11, 12 and 13 with elements 2-4 of structures 1 and auxiliary kerchiefs are used between them, which conventionally not shown. The connection of the elements of the block is carried out mainly in welding. It is possible to assemble individual components on bolts. Suspension supports 14 and 18 are made of strip steel or round steel. The proposed device is mounted element by element and from enlarged modules on the stocks, ensuring the subsequent horizontal sliding of each spatial block to the design position with the help of winches and a system of cables. It is allowed to mount the equipment located between the elements of the unit directly on the stocks before sliding the unit into the design position. After installation of the next block or group of blocks on the top of the Cy 2 stack, attached to it, flooring 20, for example, in the form of stamped profiled sheets of galvanized steel. Thermal insulation 21 is placed on top of decking. The proposed spatial assembly block spans. provides a simplified installation of large-span structures by combining into one block at least three truss girders and their simultaneous sliding as a single spatial structure, as well as through more technological, carried out on stationary stocks, assembling large-sized equipment placed between the elements of the block formula of the invention The spatial mounting block of span structures of the building structure, including flat through-bearing elements and core links between them in the upper, lower and transverse planes, which also, in order to increase rigidity and enable equipment to be placed between the elements of the block, the supporting elements of the block are made in the form of truss beams, the top one of which is broken in the form of a double-sided I-beam, and a puff in the form of an I-beam, the flanges of which are arranged in a vertical plane, each beam in the nodes of the bearing provided with one or several vertical plates with rigidly attached to the bottom perpendicular to the plates Weller with lowered down shelves, 2. The unit according to claim 1, characterized in that the uppermost co-slingel beams are provided with a suspension (with the first supports for fastening the equipment / vanes, and puffs - supports for service bridges and elements for fastening a suspended prtolka.
