Description
Technical field
This utility model relates to a support arrangement, particularly relates to a kind of large-span gantry frame.
Background technology
Portal frame is mainly made up of crossbeam, column, chassis, nose girder and fulcrum five part, outside as the support of jacking equipment, is also seen everywhere on a highway. Owing to two posts are just as interwined dragon post, image and claim portal frame; In recent years, China puts into substantial amounts of manpower and materials in transport development, allows the traffic of all parts of the country all obtain more convenient, facilitates the trip of the common people, and the spring transportation being also annual reduces burden. Portal frame have also been obtained on a highway and is widely applied, highway is set up portal frame be not only able to arrange LED screen to carry out road condition advisory, can also arrange the equipment such as holes probe, vehicular traffic is exercised supervision, there is vehicle accident because of the problem such as hypervelocity in the avoiding of maximum possible.
And the span of current portal frame is all smaller, the portal frame of little span is easily fixed, it is simple to build, but highway is wider due to road surface, and the portal frame of little span cannot be suitable for; Also there is the portal frame of some big spans on the market, but owing to span problem crossbeam center is all not readily available, give to build and bring very big trouble, and easily go out security incident, there is deficiency, it is impossible to meet the demand of social development.
In sum, for the defect of prior art, it is accordingly required in particular to a kind of large-span gantry frame, to solve the deficiencies in the prior art.
Utility model content
In use not enough for portal frame in prior art, actual use is brought very big impact, the utility model proposes a kind of large-span gantry frame, modern design, makes portal frame more reliable and more stable, improves security performance, Practical Performance is excellent, has solved the defect of prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of large-span gantry frame, including column, column is connected in ground surface by fixing seat, column top is provided with the support plate fixing with crossbeam, the axle center of crossbeam and the axis coinciding of column, and the top of crossbeam is provided with guard rail, the passage port of guard rail is provided with the stair of linking column, the central authorities of guard rail are fixed with electrical screen by installing rack, and the both sides of guard rail are provided with adjustment slideway, regulate in slideway and have discharging rod by fixing screw lock.
Further, described crossbeam be internally provided with reinforcement.
Further, adopting detachable connection between described crossbeam and column, the surrounding of crossbeam is provided with the fillet of transitions smooth.
Further, the shape of described reinforcement is triangular in shape.
The beneficial effects of the utility model are: this product structure is simple, design science, by calculate obtain crossbeam focus point then with column center superposition, it is thus achieved that a kind of trace skew asymmetric portal frame constructing structure, make portal frame more reliable and more stable, improve security performance, adapt to the demand of social development, Practical Performance is excellent, it is convenient for the dismounting installed, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
This utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
100-column in figure, 110-fixes seat, 120-stair, 130-crossbeam, 140-reinforcement, 160-discharging rod, 170-guard rail, and 180-electrical screen, 190-props up support plate.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
Referring to Fig. 1, a kind of large-span gantry frame, including column 100, column 100 is connected in ground surface by fixing seat 110, column 100 top is provided with the support plate 190 fixing with crossbeam 130, the axle center of crossbeam 130 and the axis coinciding of column 100, the top of crossbeam 130 is provided with guard rail 170, the passage port of guard rail 170 is provided with the stair 120 of linking column 100, the central authorities of guard rail 170 are fixed with electrical screen 180 by installing rack, the both sides of guard rail 170 are provided with adjustment slideway, regulate in slideway and have discharging rod 160 by fixing screw lock.
It addition, crossbeam 130 be internally provided with reinforcement 140, the shape of reinforcement 140 is triangular in shape. Adopting detachable connection between crossbeam 130 and column 100, the surrounding of crossbeam 130 is provided with the fillet of transitions smooth. Column 100 is internal is hollow structure, and column 100 adopts material to be steel alloy.
Axis coinciding by the axle center of crossbeam and column, the span of portal frame can be effectively increased, enhance the security performance that portal frame uses, and it is easy to be fixed on electrical screen the surface of guard rail, and discharging rod is installed, not only Practical Performance is excellent, and exquisite appearance, it is easy to the displaying to electrical screen surface information, makes portal frame more reliable and more stable.
This utility model is effective is: simple in construction, design science, by calculate obtain crossbeam focus point then with column center superposition, it is thus achieved that a kind of trace skew asymmetric portal frame constructing structure, make portal frame more reliable and more stable, improve security performance, adapt to the demand of social development, Practical Performance is excellent, it is convenient for the dismounting installed, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
