Specific embodiment
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail.
Embodiment: a kind of to be set for the hoisting frame without bearing large space Steel Truss Beam, including level referring to Fig. 1 to Fig. 4
The H profile steel cross bar 1 set, one end of the H profile steel cross bar 1 are fixing end, and the other end is overhanging end.It is set vertically on H profile steel cross bar 1
There is a compression vertical bar 2, the lower end of the compression vertical bar 2 is fixedly connected with H profile steel cross bar 1, and the lower end of compression vertical bar 2 and H profile steel
The distance between fixing end of cross bar 1 is greater than the distance between itself and the overhanging end of H profile steel cross bar 1；When it is implemented, it is perpendicular to be pressurized
The distance between fixing end of the lower end of bar 2 and H profile steel cross bar 1 is outstanding for its (lower end of compression vertical bar 2) and H profile steel cross bar 1
Twice for choosing the distance between end；In such manner, it is possible to keep the bearing capacity of entire hoisting frame stronger, stability is more preferable, better reliability.
Several connecting screw holes are respectively arranged at its both sides of the edge in the downside of H profile steel cross bar 1, in order to install fixation.
Fixing end tension diagonal 3 and overhanging end tension diagonal 4 are respectively equipped in the two sides of compression vertical bar 2.Wherein, fixing end
The upper end of tension diagonal 3 is fixedly connected with the upper end of compression vertical bar 2, and lower end is tilted to the fixation extreme direction of H profile steel cross bar 1, and
It is fixedly connected with H profile steel cross bar 1.The upper end of overhanging end tension diagonal 4 is fixedly connected with the upper end of compression vertical bar 2, and lower end is to H-type
The overhanging extreme direction of steel cross bar 1 tilts, and is fixedly connected with H profile steel cross bar 1.In production process, in H profile steel cross bar 1
Between fixing end tension diagonal 3 and vertical and inclination is distributed between H profile steel cross bar 1 and overhanging end tension diagonal 4 to set
The reinforced pull rod 7 set；So as to further promote the stability and intensity of entire hoisting frame.
It is fixed with jack chassis 5 on the upside of the overhanging end of H profile steel cross bar 1, one is equipped on the jack chassis 5 and is worn
Core type jack 6.The centre-hole jack 6 is vertically arranged (i.e. the axial line of centre-hole jack 6 is vertical), at jack bottom
On disk 5 and H profile steel cross bar 1, equipped with several through-holes corresponding with (steel strand wires 11) via hole on centre-hole jack 6.It is wearing
It is equipped with limiter between core type jack 6 and jack chassis 5, moveable anchor is equipped in the upper end of centre-hole jack 6, by wearing
Core type jack 6 cooperates limiter and moveable anchor to be able to carry out the lifting (tensioning) of steel strand wires 11, which is construction row
Mature technology means in industry.
It further include a sub-truss 8, the height of the sub-truss 8 and steel truss fine strain of millet to be hoisted during actual processing
Height it is consistent so that Steel Truss Beam 12 can be promoted to the upper end of tower (column) 10 in lifting process.The H profile steel
Cross bar 1 is fixedly connected with the sub-truss 8, and it overhangs end and stretches out from one end of sub-truss 8；Wherein, H profile steel cross bar 1 with
The sub-truss 8 welds together, to guarantee to have enough support strengths；Or H profile steel cross bar 1 and the sub-truss 8
It is connected by connection bolt, and it is easy to disassemble.
As an implementation, further include pre-embedded steel slab 9, in construction process, by the pre-embedded steel slab 9 be embedded in
The top of tower (column) 10；Then the downside of institute's sub-truss 8 is fixedly connected by connection bolt with pre-embedded steel slab 9, and makes H-type
The overhanging end of steel cross bar 1 is stretched out from the side of pre-embedded steel slab 9, and stretches out the side of tower (column) 10；In this way, very heavy by punching
Cooperation limiter and moveable anchor directly can promote Steel Truss Beam 12 by steel strand wires 11, only without carrying out
Vertical bearing does not need the Large-scale Hoistings equipment such as crane yet, makes to lift more convenient, quick, more efficient.
During practice of construction, two hoisting frames are respectively set on the top for the tower (column) 10 that two need to install steel truss two, and
The overhanging end of two hoisting frames is stretched out from the adjacent side of Liang Ta (column) 10；And two hoisting frames are connected by connecting rod 13, with
Improve the intensity and connective stability of two hoisting frames.In this way, the cooperation of 4 hoisting frames by two towers (column) 10 top, energy
Enough liftings for easily and fast and reliablely and stablely carrying out steel truss two.
Finally, it should be noted that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application technology
Scheme, those skilled in the art should understand that, those are modified to the technical solution of the utility model or are equal
Replacement, without departing from the objective and range of the technical program, should all cover in the scope of the claims of the utility model.
