Abstract
The utility model relates to a force bearing structure, particularly a steel-structure door type steel frame used on buildings and bridges. The prestressing-force steel-structure door type steel frame comprises an upright post and a Y-shaped beam, wherein a traction force device which is impressed with the prestressing force is arranged on the upright post and the Y-shaped beam; the traction force device is a traction cable arranged on the Y-shaped beam and the upright post, can be a traction cable arranged on a supporting rod of the Y-shaped beam and the upright post, and can be other forms which can conduct prestressing force. The utility model has the advantages that the prestressed traction device which is impressed with the prestressing force in advance is arranged on the corresponding position of the steel-structure door type steel frame according to different construction and use conditions, the internal force of the door type steel frame can be balanced, thereby, the load capability and the displacement resistance capability can be enlarged under the condition that the cross section is not increased, and the utility model has wide application range.
Description
Technical field
The utility model relates to a kind of load-carrying construction, especially for the steel work gate-type rigid frame on building, the bridge.
Background technology
The steel work gate-type rigid frame of using in the engineering, before building up and bearing service load, general effect of only bearing from heavy load, this steel work gate-type rigid frame is made up of shaped steel and steel plate, fully under the service load effect, the internal force that produces is usually very unbalanced, its Cross section Design is to determine by required maximum stress, and therefore, the most of positions of this kind structure stress is not full.In addition, because portal-rigid frames are a kind of change structures of striding, integral rigidity is poor than bent structure, therefore often produces bigger amount of deflection and side displacement, particularly at bigger use load, and under large span, highly situation, and when crane load is arranged, all the more so.In order to satisfy the requirement of degree of deformation, have to increase the door frame sectional area, cause waste of material, very uneconomical.
Summary of the invention
The purpose of this utility model is to provide a kind of difference according to bearing load for solving above-mentioned the deficiencies in the prior art, apply prestressing force in the relevant position, make internal stress comparatively average and displacement is less, thus the steel work gate-type rigid frame with economic effect of raising weight bearing power.
The utility model is that the technical scheme that adopts that achieves the above object is: a kind of steel work gate-type rigid frame, and it comprises column and herringbone crossbeam, and column and herringbone crossbeam are provided with and have applied prestressed puller system.
Described puller system is the drag-line that is arranged on herringbone crossbeam and the column, also can be to be arranged at the strut on herringbone crossbeam and the column and the combination of drag-line, and other can conduct the form of stress.On puller system, applied the stress value of optimizing in advance, can be arranged on the different position of different rigid frames according to different demands, prestressed applying method can adopt the direct stretch-draw of tensioner such as jack, also can pass through different stretching modes such as electrothermal way, deflection method and transverse stretching.
The beneficial effects of the utility model are: according to different constructions and behavior in service, setting has applied prestressed puller system in advance in steel work gate-type rigid frame relevant position, internal force that can balanced portal-rigid frames, make it under the situation that does not increase sectional area, strengthen its supporting capacity and rigidity, have wider range of application.
The utility model is further elaborated by embodiment below in conjunction with accompanying drawing, but embodiment does not limit protection domain of the present utility model.
Description of drawings
Fig. 1 is the structural representation of steel work gate-type rigid frame among the embodiment 1;
Fig. 2 is the structural representation of steel work gate-type rigid frame among the embodiment 2.
The specific embodiment
Embodiment 1:
As shown in Figure 1, a kind of steel work gate-type rigid frame, it comprises column 1 and herringbone crossbeam 2, the drag-line 4 that its puller system 3 is provided with on cant beam on the herringbone crossbeam 2 and column 1, applied the prestressing force of optimizing when on two drag-lines 4, installing, make its satisfy same safe, use, under the condition of construction, can reduce the sectional area of door frame, to save cost, reach economic effect.
Embodiment 2:
A kind of steel work gate-type rigid frame as shown in Figure 2, described puller system 3 comprises the support bar 5 that is arranged at the drag-line 4 on herringbone crossbeam 2, the column 1 and is provided with below the middle part of herringbone crossbeam 2, drag-line 4 cross-over connections on the herringbone crossbeam 2 are in two of herringbone crossbeam 2 end that cornices, and with the lower end overlap joint of support bar 5.In drag-line 4, applied the prestressing force of optimizing in advance, after construction finishes, by the mode of outer support of support bar or direct stretch-draw, adjusted prestressing force, to reach economic effect.
Claims (3)
1, a kind of prestressed steel structure portal-rigid frames, it comprises column (1) and herringbone crossbeam (2), it is characterized in that: column (1) and herringbone crossbeam (2) are provided with and have applied prestressed puller system (3).
2, a kind of prestressed steel structure portal-rigid frames according to claim 1 is characterized in that: described puller system (3) is for being arranged at the drag-line (4) on herringbone crossbeam (2) and the column (1).
