Abstract
The utility model discloses a universal assembling jig frame for any trusses and relates to the technical field of building steel structure construction. The universal assembling jig frame comprises adjusting opening-type supporting frames, an adjustable jig frame base and universal wheels mounted at the bottom of the base and adjustable in height. Each pair of the adjusting opening-type supporting frames comprises a left-side supporting frame and a right-side supporting frame, the bottoms of each left-side supporting frame and the corresponding right-side supporting frame are positioned on the left side and right side of the adjustable jig frame base and are in rotation through bolts, and the left-side supporting frames and the right-side supporting frames are matched with rotatable hydraulic jacks arranged on the adjustable-type jig frame base to adjust opening angle and height through lug plates arranged at different positions on the left-side supporting frames and the right-side supporting frames. By the universal assembling jig frame, opening-closing-type structures of any space trusses can be assembled; after truss assembling is completed, convenience and freeness in demoulding of the jig frame are realized; the universal wheels adjustable in height are mounted at the bottom of the adjustable jig frame base, so that the problem of unevenness of a site can be solved, high efficiency and convenience in construction are realized, and safety in assembling is improved.
Description
Technical field
The utility model relates to construction steel structure technical field of construction, is specifically related to a kind of omnipotent assembled moulding bed of truss arbitrarily, is mainly used in the structure of large span.
Background technology
In recent years, along with development and the maturation of steel work technology, particularly the application of large-span truss structure is more and more extensive.The plane with triangular element or space structures that trussed construction is generally comprised of straight rod member, under load action, truss member mainly bears axial tension or pressure, thereby can make full use of the intensity of material, when span is larger, comparable solid web girder is saved material, alleviate deadweight and increase rigidity, therefore be widely used in the structure of large span.The making step that all kinds of steel structure truss are general and the problem facing have:
(1) prepare assembled place.Because truss fabrication required precision is high, therefore need smooth assembled place, to guarantee to make precision.
(2) create put together to pack moulding bed.When each quasi-truss size is different, for guaranteeing truss fabrication precision, need to be according to drawing content, make the corresponding moulding bed of installing, for the placement positioning of truss member, during making, member location, need to carry out tack weld to member.
(3), after truss fabrication, need to excise the solder joint of temporary fixed use, then depanning.
In order to realize construction economy type, high efficiency, the unification of safety, needs to propose and design a kind of rationally effective constructure scheme.The utility model proposes that a kind of not only, to constructing operation facility, construction cost is low for any assembled openable moulding bed of space truss, operating efficiency is high simultaneously, when reducing construction cost, contributes to the reduction of erection time for this reason, and this case produces thus.
Utility model content
For above-mentioned prior art, the purpose of this utility model is to provide a kind of omnipotent assembled moulding bed of truss arbitrarily, be intended to solve and work as truss size not for the moment, every kind of truss all needs independent create put together to pack moulding bed, workload is large, and being finished later moulding bed often can not secondary utilization, the technical problem of waste material.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of omnipotent assembled moulding bed of truss arbitrarily, it is characterized in that, comprise and regulate open-type bracing frame, the adjustable for height universal wheel that adjustable molding bed pedestal and this base bottom are installed, described every pair regulates open-type bracing frame to comprise left side bracing frame and right side bracing frame, the bottom of left side bracing frame and right side bracing frame is positioned at the adjustable molding bed pedestal left and right sides and forms and rotate with bolt, the otic placode that passes through diverse location on it of left side bracing frame and right side bracing frame coordinates regulating opening angle and height with the rotating hydraulic jack arranging on adjustable molding bed pedestal.
Described left side bracing frame and right side bracing frame are symmetricly set on left side bracing frame and right side bracing frame.
The crossbeam of described adjustable molding bed pedestal is coordinated and is formed by bearing pin and hydraulic jack, can carry out horizontal direction according to the assembled truss width of wish and regulate arbitrarily.
Compared with prior art, the utlity model has following beneficial effect:
The shortcomings such as one, the utility model has made up the assembled process complexity of traditional moulding bed, and assembled amount of high-altitude operation is large, the low and tread flaking process inconvenience of safety, retractable structure that can assembled any space truss, truss is assembled complete after, tread flaking is freely convenient.
Two, at the adjustable universal wheel of the bottom of adjustable molding bed pedestal setting height(from bottom), can solve the place problem that is uneven, jack and pulley carry out the location of high-altitude chord member, guarantee that whole space truss is assembled, welding, the continuity of tread flaking, realizes the efficient and convenient of construction, the safety that has improved assembled process.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model will be further described.
A kind of omnipotent assembled moulding bed of truss arbitrarily, it comprises the adjustable for height universal wheel that regulates open-type bracing frame, adjustable molding bed pedestal and this base bottom to install, described every pair regulates open-type bracing frame to comprise left side bracing frame and right side bracing frame, the bottom of left side bracing frame and right side bracing frame is positioned at the adjustable molding bed pedestal left and right sides and forms and rotate with bolt, and the otic placode that passes through diverse location on it of left side bracing frame and right side bracing frame coordinates regulating opening angle and height with the rotating hydraulic jack arranging on adjustable molding bed pedestal.
Adjustable molding bed pedestal lower end is provided with the universal wheel of upper and lower height-adjustable, can carry out leveling according to the assembled place of job site, makes truss and not limited by site condition.And the crossbeam of adjustable molding bed pedestal is coordinated and is formed by bearing pin and hydraulic jack, can carry out horizontal direction according to the assembled truss width of wish and regulate arbitrarily.Crossbeam can also can be used as moulding bed bed die and operating platform beam is used.
