Abstract
The invention discloses a supporting-free double-truss structure which is provided with truss single sheets. Top booms and lower booms are fixedly connected onto the truss single sheets, and a cross bar is arranged between the truss single sheets. The truss single sheets are symmetrically arranged at two ends of the cross bar and comprises inner truss single sheets and outer truss single sheets, and the inner truss single sheets are fixedly connected with the outer truss single sheets in a contact mode. The inner truss single sheets and the outer truss single sheets are spliced, two single sheet vertical rods are reinforced through small welding blocks, the top booms and the lower booms are fixedly connected through bolts, and therefore the supporting-free double-truss structure is simple, safe and stable in whole structure and simple and convenient in manufacturing process, and greatly saves space occupation of elevators compared with supporting-free truss structures with depth deepened middle trusses.
Description
technical field:
the present invention relates to a kind of staircase component, particularly relate to a kind of unsupported two-spar structure.
background technology:
Truss agent structure in staircase is the entirety that each hard ware is formed by connecting by modes such as welding, and two truss and chord member, longeron, the quantity of brace etc. is the twice of common truss, in the truss piling unitized construction, carry out calculating according to 5.2.5 support structure designs in standard GB/T 16899-2011 to check, and in view of the requirement of architectural design, when the hoisting depth of escalator reach produce the scope of midship mounting is set time, time even up to more than 10m, inaccurate escalator arranges midship mounting, and some current intensification middle part truss degree of depth classes design without supporting girder structure, because the space taken is larger, be unfavorable for unit design and the architectural design of truss.
summary of the invention:
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, safety and firmness and take up room little of supporting two-spar structure.
For solving the problem, the present invention is achieved by the following technical solutions:
A kind of without supporting two-spar structure, there is truss monolithic, truss monolithic is fixedly connected with top boom and lower boom, a cross bar is provided with between described truss monolithic, described truss single-sheet symmetric is arranged at cross bar both ends, described truss monolithic comprises interior truss monolithic and outer truss monolithic, and described interior truss monolithic contacts with outer truss monolithic and is fixedly connected with.
As preferably, for make described interior truss monolithic be connected between outer truss monolithic more firm, adopt between described interior truss monolithic and the montant of outer truss monolithic and weld fritter and be fastenedly connected.
As preferably, described without supporting two truss integral structure safety and firmness more for making, described truss monolithic is connected with bolted between top boom and lower boom.
As preferably, for making described top boom and being comparatively easily connected and fixed between lower boom and truss monolithic and can having better outward appearance, described top boom and lower boom are set to the T-shaped steel structure of cross-sectional plane.
Compared with prior art, usefulness of the present invention is: this without supporting two-spar structure, owing to adopting inside and outside truss monolithic splicing construction, two monolithic montants adopt welding fritter to reinforce, upper and lower chord member then connects with bolted, and integral structure is simple, safety and firmness, and manufacture craft is easy, and with intensification middle part truss degree of depth class without compared with sub-truss, the larger space of having saved shared by staircase.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is Facad structure schematic diagram of the present invention
Fig. 2 is the structural representation of the present invention when being arranged on staircase
In figure: 1, truss monolithic 2, top boom 3, lower boom 4, cross bar 5, interior truss monolithic 6, outer truss monolithic 7, welding fritter
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The present invention is a kind of without supporting two-spar structure, as Fig. 1, shown in Fig. 2, there is truss monolithic 1, truss monolithic 1 is fixedly connected with top boom 2 and lower boom 3, for making described top boom 2 and being more easily connected and fixed between lower boom 3 and truss monolithic 1 and better outward appearance can be had, described top boom 2 and lower boom 3 are set to the T-shaped steel structure of cross-sectional plane, a cross bar 4 is provided with between described truss monolithic 1, described truss monolithic 1 is symmetricly set in cross bar 4 both ends, described truss monolithic 1 comprises interior truss monolithic 5 and outer truss monolithic 6, described interior truss monolithic 5 contacts with outer truss monolithic 6 and is fixedly connected with, preferably, adopt between described interior truss monolithic 5 and the montant of outer truss monolithic 6 and weld fritter 7 and be fastenedly connected, thus make described interior truss monolithic 5 be connected between outer truss monolithic 6 more firm, difficult drop-off, structure safety and firmness and technique is simple to operation more, in addition, preferably, described truss monolithic 1 is connected with bolted between top boom 2 and lower boom 3, thus also make described without supporting two truss integral structure safety and firmness more, enhance the support strength of whole truss.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
