Abstract
The utility model provides a movable safety net device which is applicable to hoisting construction of a roofing structure in steel structure construction. The movable safety net device comprises a safety net and a thick steel wire rope, wherein the thick steel wire rope is arranged along the going-forwards direction of the safety net; the safety net is arranged in the direction which is vertical to the going-forwards direction; a thin steel wire rope is used for connecting in series; the thin steel wire rope and the thick steel wire rope are connected by a sleeve ring so that the thin steel wire rope can drive the safety net to slide on the thick steel wire rope; a detachable movable clamp is mounted on a steel column on a position of the safety net to be paved of the safety net; the movable clamp is provided with a guide pulley wheel for the thick steel wire rope to penetrate; a labor-saving tensioning device for tensioning the thin steel wire rope is mounted below the thin steel wire rope. With the adoption of the device, the detachment and the reinstallation of the safety net can be simplified, the manpower is saved and the hoisting efficiency is improved.
Description
Technical field
The utility model belongs to Construction of Steel Structure aid field, refers more particularly to the movable safety net arrangement that is applicable to roof structure lifting construction in Construction of Steel Structure.
Background technology
In today that people-oriented, steel work safe construction is particularly important, for guaranteeing under the prerequisite of personal security, high-rise roof and factory building roof need to lay safety net when lifting construction comprehensively, after laying, can carry out lifting construction, for example: 1 ~ 31 line roofing, when lifting, 1 ~ 5 line first all need to be laid to safety net, safety net needs colligation on roof girder, after roofing secondary beam and secondary member have all lifted, after again safety rope and installation net all being removed, moving to 5 ~ 10 lines, re-starting colligation lays again, the like by roofing rigging out, the method is time-consuming, installation and mobile security net have taken the time that lifts 80%, very impracticable.
Therefore need to design a kind of mobile security net arrangement of new raising lifting efficiency.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of and simplifies the dismounting of safety net and again install, and saves manually, improves the movable safety net arrangement of lifting efficiency.
The utility model solves the technical scheme that its technical problem adopts:
Movable safety net arrangement, include safety net and coarse-wire rope, the direction setting that coarse-wire rope advances along safety net, it is characterized in that: described safety net is on perpendicular to direction of advance, the series connection of employing seizing wire, between seizing wire and coarse-wire rope, adopt the collar to connect, make seizing wire can drive safety net to slide on coarse-wire rope; On the steel column in safety net place to be laid, dismountable mobile holder is installed, the leading block passing for coarse-wire rope is installed on mobile holder, described seizing wire below is provided with the laborsaving tensioning apparatus that seizing wire can be tightened.
In such scheme, described mobile holder is U-shaped jig, is provided with for being fixed on the bolt on steel column, and at U-shaped jig upper surface, snap ring is installed on U-shaped jig, is provided with leading block in snap ring.
In such scheme, described laborsaving tensioning apparatus includes pulley and the jack being arranged on steel column, and on steel column, is provided with fixed point, and seizing wire passes successively pulley, jack and is fixed on fixed point and tightens.
Main beneficial effect of the present utility model is:
1, effectively solve the conflict of safety net laying and lifting construction.
2, improve efficiency and the lifting construction efficiency of mobile security net, guaranteed to a great extent the safety of lifting construction, completed safely and efficiently lifting construction task.
3, reduce labor intensity, use flexibly, easy and simple to handle, single without training, can complete whole operating process, and without auxiliary equipment.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure figure
Fig. 2 is the utility model embodiment mobile holder structure chart
Fig. 3 is the laborsaving tensioning device structure figure of the utility model embodiment
In figure: 1, coarse-wire rope; 2, seizing wire; 3, steel column; 4, safety net; 5, mobile holder; 6, leading block; 7, bolt; 8, snap ring; 9, pulley; 10, jack.
The specific embodiment
Below in conjunction with the specific embodiment, to the utility model, embodiment is further described:
Movable safety net arrangement as shown in Figure 1, include safety net 4 and for the coarse-wire rope 1 of Hoisting Security net 4, the direction setting that coarse-wire rope 1 advances along safety net 4, described safety net 4 is on perpendicular to direction of advance, adopt seizing wire 2 series connection, 1 of seizing wire 2 and coarse-wire rope adopts the collar to be connected, make seizing wire 2 can drive safety net 4 to slide on coarse-wire rope 1, on the steel column 3 in safety net 4 places to be laid, dismountable mobile holder 5 is installed, the leading block 6 passing for coarse-wire rope 1 is installed on mobile holder 5, described seizing wire 2 belows are provided with the laborsaving tensioning apparatus that seizing wire 2 can be tightened.
In the present embodiment, mobile holder 5 is as shown in Figure 2 U-shaped jig, is provided with for being fixed on the bolt 7 on steel column 3, and at U-shaped jig upper surface, snap ring 8 is installed on U-shaped jig, is provided with leading block 6 in snap ring 8.
In the present embodiment, laborsaving tensioning apparatus as shown in Figure 3 includes pulley 9 and the jack 10 being arranged on steel column 3, and is provided with fixed point on steel column 3, and seizing wire 2 passes successively pulley 9, jack 10 and is fixed on fixed point and tightens.
During use, with seizing wire, safety net is altered and is convenient to safety net to tighten, and four end be fixed on mobile holder, because of safety net deadweight, two ends can sink, and 10 mobile holders therefore two ends distribute, because construction is in high-altitude, personnel pull safety net safe not on roofing, therefore a work-saving device is set at place, ground with jack and pulley, safety net are pulled to two wires until safety net is tightened comprehensively from a line.After this region lifting construction, unclamp a line and two wires mobile holder, by safety net along coarse-wire rope, the stretching AB that arrives is across this region of two ~ tri-lines, the mobile holder of one line is moved on to three lines, according to above method, safety net, by that analogy organizing construction are installed again.
According to above time method, reduce labor intensity, use flexibly, easy and simple to handle, single without training, can complete whole operating process, and without auxiliary equipment, need in the past 1 workaday construction, and only needed now just can complete for 2 hours, greatly improved efficiency of construction.That installs is fairly simple, and cost is low, can be widely used, and by the fixedly safety net in high-altitude, move to ground, has greatly evaded security risk.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not depart from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention of the present utility model also comprises these changes and is out of shape interior.
