RU73000U1 - CABLE LATCH FOR LONG-SPAN STRUCTURE - Google Patents

Abstract

A cable stay contains blocks 2 suspended from the support pylon 1 on cables 3, assembled from trusses and structurally acting as stiffeners (i.e., a stiffener is a block assembled from two trusses). Blocks 2 are located radially to the pylon 1, which is made hollow and installed outside the premises to be blocked. Each block 2 end, facing the side of the pylon 1, is cantilevered on a fixed frame 4 of the overlapping room. The seams between the blocks 2 are located between the paired blocks. The structure is cut with the indicated expansion joints in accordance with the technical requirements: seismicity, climatic conditions, underworking of the construction area, etc. Accordingly, the volume of the structure is related to the overlap area. Pylon 1 is made in the form of a hollow pre-stressed tower type television. The blocks 2 are rigidly fastened to the frame 4. The trusses of the spatial blocks 2 are made of steel tubular elements such as an arrow of a tower crane. Enclosing structures (frame) limit the territory and can partially serve as load-bearing elements up to 30% of their perimeter. At the same time, the installation of blocks is simplified, the consumption of building materials for the construction of the block support is reduced, the laboriousness of the device of expansion joints of a minimum length is reduced, the efficiency of using the area is increased.

Description

The utility model relates to construction, in particular to cable-stayed construction of ceilings and can be used to overlap a large territory.

Known cable-stayed overlapping, including the carrier and stabilizing belts, forming cable-stayed networks with quadrangular cells offset in plan relative to each other, and united by zigzag braces in intersecting inclined cable-stayed trusses with a triangular geometrically unchanged lattice, characterized in that the carrier and stabilizing belts, and also the diagonal lattice connecting them is made by continuous zigzag cables that are passed through the cable-stayed networks installed in the corners of the cables nye closed profile elements with a curved inner surface to form therebetween a mutually intersecting inclined portions of cable truss (RU №2099485, 1997).

The disadvantages of this cable-stayed overlap are the complexity of the design of zigzag cables, the high consumption of building materials, the complexity of installation with the need to form mutually intersecting trusses and the device of a large number of expansion joints, insufficient efficiency of use of the area.

A cable-stayed ceiling is also known, comprising blocks assembled from trusses suspended from a cable-stayed pylon (US No. D270570, "Dual unit cable stay building", 1983, prototype).

The disadvantages of this cable-stayed overlap are the difficulty of installing blocks, the high consumption of building materials for distributed around the perimeter of the block supports, the complexity of installation with the need to form a large number of expansion joints, the insufficient efficiency of using the area.

The technical task of the utility model is to create an effective cable-stayed overlap and expand the arsenal of cable-stayed ceilings.

The technical result that provides a solution to the problem is that the installation of blocks is simplified, the consumption of building materials is reduced

the support structure of the blocks, reduced the complexity of the device of expansion joints of minimal length, increased efficiency of use of the area.

The essence of the utility model consists in the fact that the cable-stayed overlap contains blocks assembled from trusses suspended from the pylon on cables and the blocks are located radially to the pylon, which is hollow and installed outside the premises to be blocked, and each block with its end facing the pylon is cantilevered on a fixed frame of the room to be blocked.

Preferably, the pylon is made in the form of a hollow prestressed tower, the blocks are rigidly fastened to the frame, and the trusses of the blocks are made of steel tubular elements.

The drawing of figure 1 shows a structural diagram of the cable-stayed overlap on both sides of the pylon, figure 2 is a plan view of figure 1, figure 3 is a diagram of the expansion joints in the overlap, figure 4 is a schematic diagram of the support block.

A cable stay contains blocks 2 suspended from a support pylon 1 on cables 3, assembled from trusses (not indicated) and structurally acting as stiffeners (i.e., a stiffener - a block assembled from two trusses). Blocks 2 are located radially to the pylon 1, which is made hollow and installed outside the premises to be blocked. Each block 2 end, facing the side of the pylon 1, is cantilevered on a fixed frame 4 of the overlapping room. The seams between the blocks 2 are indicated by a double dotted line in figure 3 and are located between the paired blocks - the usual classic method of seams. The structure is cut with the indicated expansion joints in accordance with the technical requirements: seismicity, climatic conditions, underworking of the construction area, etc. Accordingly, the volume of the structure is related to the overlap area.

Pylon 1 is made in the form of a hollow pre-stressed tower type television.

Blocks 2 are rigidly fastened to the frame 4.

The trusses of the spatial blocks 2 are made of steel tubular elements (not shown), such as a boom of a tower crane. Enclosing

structures (frame) limit the territory and can partially serve as load-bearing elements up to 30% of their perimeter.

Cable-stayed overlap is operated as follows.

Almost the entire area under the ceiling is useful as the territory of public buildings, airport terminals, hangars, assembly shops for large structures (air buses, spaceships, dry docks), film studios of film studios, arenas, sports facilities, train stations, railway stations with driveways , industrial and agricultural enterprises, botanical gardens.

The execution of the pylon 1 hollow allows you to use its volume, for example, as a room of auxiliary services.

For this design, as a rule, one, but no more than two, pylons 1 is sufficient. Blocks 2 are supported at one end on the frame 4 and the horizontal compressive forces arising in the block 2 are transferred to the base of the frame 4. The radial arrangement of the blocks 2 allows the device to be constructed expansion joints and as a result - overlap with a large area. Block - spatial design, calculated in addition to the vertical loads on additional axial forces arising from the structural scheme of the cable-stayed ceiling.

The building envelope serves as a bearing partially up to 30% of its perimeter, i.e. the frame 4 of the perimeter of the structure, facing the pylon 1, carries the load from the supporting end of the blocks 2.

The architect uses the remaining free areas of the facade of the building for his creative imagination.

Thus, an effective cable-stayed overlap was created and the arsenal of cable-stayed ceilings was expanded.

At the same time, the installation of blocks is simplified, the consumption of building materials for the construction of the block support is reduced, the laboriousness of the device of expansion joints of a minimum length is reduced, the efficiency of using the area is increased.
