Abstract
The utility model relates to a bottom frame, which comprises a connecting rod, a first hollow support rod and a second hollow support rod. The bottom end of the first support rod is connected with the connecting rod through a base II, the bottom end of the second support rod is connected with the connecting rod through a base IV, a base I is arranged at the upper end of the first support rod, and a base III is arranged at the upper end of the second support rod. The bottom frame has the advantages that a beam of an operating platform is respectively placed in the first hollow support rod and the second hollow support rod and is fixed by pins, accordingly, the bottom frame is structurally simplified, is convenient in installation and connection and is safe and practical, and use effects are improved.
Description
Technical field
The utility model relates to a kind of underframe.
Background technology
Existing building need be used job platform mostly in the process of construction; Underframe is as important building block in the job platform frame; Existing underframe is connected with the job platform frame mostly and connects through overlapping, and such connected mode exists connection insecure, might produce injury to the user; Result of use is poor, poor safety performance.
The utility model content
The technical problem that the utility model will solve is that the underframe connection is insecure, and application life is short, thereby a kind of underframe is provided.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of underframe; Comprise first support bar of connecting rod, hollow shape, second support bar of hollow shape; The bottom of said first support bar links to each other with connecting rod through base II, the bottom of said second support bar through base IV link to each other with connecting rod, the upper end of said first support bar is provided with base I, the upper end of said second support bar is provided with base III.
Preferably, be equipped with groove on said base I, base II, base III, the base IV, be provided with the connecting hole that matches with first support bar, second support bar in the said groove, easy for installation, simple in structure.
Preferably, said first support bar, second support bar all pass connecting hole and link to each other with base I, base II, base III, base IV, are convenient to install, and simple in structure, result of use is good.
Preferably, be respectively equipped with through hole on the sidewall of said base I, base II, base III, base IV, simple in structure, be convenient to install.
Preferably, said first support bar, second support bar are provided with at least one fixing hole, and be simple in structure, is convenient to install.
Preferably, said connecting rod is provided with at least one hole, and is simple in structure, is convenient to install.
Preferably, through being welded to connect, also can be convenient to ways of connecting between said connecting rod, first support bar, second support bar and base I, base II, base III, the base IV, weld more firmly, safe and reliable, use simple for other.
In sum, the advantage of the utility model: the crossbeam of job platform is positioned over respectively in second support bar of first support bar and hollow shape of hollow shape, and fixes through bearing pin; Make simplifying the structure of underframe, easy for installation, easy to connect; Safe and practical, improved result of use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of a kind of underframe of the utility model;
Fig. 2 is the vertical view of the utility model Fig. 1;
Fig. 3 is the left view of the utility model Fig. 1.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of underframe comprises that second support bar 3 of first support bar 2, the hollow shape of connecting rod 1, hollow shape, the bottom of said first support bar 2 link to each other with connecting rod 1 through base II5; The bottom of said second support bar 3 through base IV7 link to each other with connecting rod 1, the upper end of said first support bar 2 is provided with base I 4, the upper end of said second support bar 3 is provided with base III6, is equipped with groove 8 on said base I 4, base II5, base III6, the base IV7; Be provided with the connecting hole that matches with first support bar 2, second support bar 3 in the said groove 8, easy for installation, simple in structure; Said first support bar 2, second support bar 3 all pass connecting hole and link to each other with base I4, base II5, base III6, base IV7, are convenient to install, and be simple in structure; Result of use is good, is respectively equipped with through hole 9 on the sidewall of said base I4, base II5, base III6, base IV7, and is simple in structure; Be convenient to install, said first support bar 2, second support bar 3 are provided with at least one fixing hole 10, and be simple in structure; Be convenient to install, said connecting rod 1 is provided with at least one hole 11, and is simple in structure; Be convenient to install; Through being welded to connect, also can be convenient to ways of connecting between said connecting rod 1, first support bar 2, second support bar 3 and base I4, base II5, base III6, the base IV7, weld more firm for other; Safe and reliable, use simple.
The crossbeam of job platform is placed in the groove 8 that is arranged at base I4, base II5, base III6, base IV7, and is fixedly connected, support is located in first support bar 2, second support bar 3 of hollow shape, and be fixedly connected through bearing pin through latch.
The crossbeam of job platform is positioned over respectively in second support bar of first support bar and hollow shape of hollow shape, and fixes, make simplifying the structure of underframe through bearing pin, easy for installation, easy to connect, safe and practical, improved result of use.
