Please refer to Fig. 1 and composition graphs 2 to Fig. 8, Fig. 1 are the schematic flow sheet choosing net method for dismounting outside scaffold of the present invention, the invention provides outside a kind of scaffold and choose net method for dismounting, comprise the following steps:
S1, provides tower crane 2 and suspension hook 1, by tower crane 2, suspension hook 1 is winched to outer cross bar 4 place chosen outside net 3 of connection.
S2, provides pull bar 5, and pull bar 5 comprises operating side 50 and is provided with the hooking end 51 of hook 52, utilizes operating side 50 to operate hook 52 to link up with in suspension hook 1, is hooked on cross bar 4 by suspension hook 1.
S3, choose over solution fastener that the diagonal brace 6 on the downside of net 3 is connected with scaffold 7 and be connected with scaffold 7 choose net 3 outward.
S4, will choose outward net 3 handling to ground by the tower crane 2 be connected with suspension hook 1.
Concrete, in step sl, as shown in Figure 2, Fig. 2 chooses tower crane in net method for dismounting to sling the view of suspension hook outside scaffold of the present invention, suspension hook 1 quantity provided is at least two, and this city embodiment is described in detail for two suspension hooks 1.The shape of suspension hook 1 can be serpentine suspension hook as shown in Figure 2, and described serpentine suspension hook can be bent by Φ 20 round steel to form.Two suspension hooks 1 are connected on the hanger 20 of tower crane 2 by connection cord 10, and two suspension hooks 1 hang on the below of hanger 20.Connection cord 10 can be wire rope.As shown in Figure 2, after two suspension hooks 1 hang on the below of hanger 20, tower crane 2 is commanded slowly to be risen by two suspension hooks 1 by ground signal work 80, until two suspension hooks 1 winch to connect outer cross bar 4 place chosen outside net 3.
After two suspension hooks 1 winch to outer cross bar 4 place chosen outside net 3 of connection, implementation step S2, the pull bar 5 provided in step s 2 as shown in Figure 3, Fig. 3 is for choosing the Tiebar structure schematic diagram provided in net method for dismounting outside scaffold of the present invention, pull bar 5 comprises operating side 50 and the hooking end 51 relative to operating side 50, hooking end 51 both sides are provided with hook 52, and pull bar 5 can be steel pipe, and two hooks 52 are welded in the both sides of the hooking end 51 of described steel pipe respectively.Next please refer to Fig. 4, Fig. 4 chooses outside scaffold of the present invention in net method for dismounting to use pull bar that described suspension hook is hooked in the view on described cross bar.As shown in Figure 4, the scaffolder 81 stood on scaffold 7 holds the operating side 50 of pull bar 5, and the hooking end 51 of operation operating side 50 is near suspension hook 1, and make the hook 52 on hooking end 51 hook suspension hook 1, then operate operating side 50, toward Zola's pull bar 5, finally make suspension hook 1 be hooked on cross bar 4.Now, as shown in Figure 4, connection cord 10 is in bending state.Wherein, the quantity of pull bar 5 corresponds to the quantity of suspension hook 1, and the quantity of pull bar 5 is also two, and preferably, in step s 2, two suspension hooks 1 are synchronously hooked on cross bar 4 by two pull bars 2.
Next please refer to Fig. 5, Fig. 5 chooses tower crane in net method for dismounting slowly to rise suspension hook until the stretching stressed view of described connection cord outside scaffold of the present invention.Suspension hook 1 is hooked in after on cross bar 4 by pull bar 5, and before implementation step S3, further comprising the steps of: tower crane 2 slowly rises suspension hook 1, until connection cord 10 stretching stressed after, remove pull bar 5.After step S2 completes, as shown in Figure 4, connection cord 10 is in bending state, if now remove pull bar 5, suspension hook 1 easily comes off from cross bar 4, comes off from cross bar 4 to prevent suspension hook 1, hanger 20 under tower crane 2 slowly rises, hanger 20 pulls connection cord 10 toward rising, because suspension hook 1 is hooked on cross bar 4, after hanger 20 rises to certain altitude, as shown in Figure 5, connection cord 10 is in stretching stress, now removes pull bar 5, and suspension hook 1 just not easily comes off from cross bar 4.
Next please refer to Fig. 6, Fig. 6 chooses the view that in net method for dismounting, cross bar cuts off according to target distance outside scaffold of the present invention.After connection cord 10 is in stretching stress, and before implementation step S3, namely choose over solution fastener that the diagonal brace 6 on the downside of net 3 is connected with scaffold 7 and be connected with scaffold 7 outer choose net 3 before, choosing net method for dismounting outside scaffold of the present invention can also comprise the following steps: determine whether cross bar 4 is set up continuously; When determining cross bar 4 for setting up continuously, as shown in Figure 6, cross bar 4 is cut off according to target distance.Described target distance can be less than or equal to 4m, namely determine whether the length of cross bar 4 is greater than described target distance, when the length of cross bar 4 is greater than 4m, as shown in Figure 6, use electric welding machine 9 cross bar 4 to be cut into the length of every section of target distance, such as just cross bar 4 is cut into the length of every section of 4m.It should be noted that, a plurality of suspension hook 1 need be positioned on one section of cross bar 4 to be lifted.
Next, please refer to Fig. 7, Fig. 7 chooses the fastener that the diagonal brace of choosing side off the net in net method for dismounting over solution is connected with scaffold and the outer view of choosing net be connected with scaffold outside scaffold of the present invention.After step S2 completes, as shown in Figure 7, scaffolder 81 and scaffolder's 82 need stand on scaffold 7 outrigger, scaffolder 81 is responsible for removing be connected with scaffold 7 outer and chooses net 3, scaffolder 82 is responsible for removing the outer fastener chosen the diagonal brace 6 on the downside of net 3 and be connected with scaffold 7, choose over solution respectively fastener that the diagonal brace 6 on the downside of net 3 is connected with scaffold 7 and be connected with scaffold 7 outer choose net 3 after, diagonal brace 6 with choose net 3 outward and hang on below cross bar 4.
Finally, please refer to Fig. 8, Fig. 8 chooses tower crane in net method for dismounting will to choose outward the view of net handling to ground outside scaffold of the present invention.After step S3 completes, choose over solution respectively fastener that the diagonal brace 6 on the downside of net 3 is connected with scaffold 7 and be connected with scaffold 7 outer choose net 3 after, namely as shown in Figure 7, commanded by ground signal work 80, tower crane 2 will choose net 3 handling to ground outside this joint, then repeat above-mentioned several step, remainingly outer choose net 3 until remove.Wholely outer choose in net 3 demolishing process, operating personnel stands on scaffold 7 outrigger, and does not need operating personnel outwards to choose inside scaffold 7 to walk outside net 3 operation, thus avoids high fall accident.
Beneficial effect of the present invention is:
According to choose outside scaffold of the present invention net method for dismounting carry out that dismounting is outer chooses net time, operating personnel stands on scaffold outrigger, and do not need operating personnel inside scaffold, outwards choose the walking operation of net outside, thus avoid high fall accident, solve operating personnel outwards need choose inside scaffold the walking of net outside with carry out choose net dismounting operation time and cause the problems such as security incident.
Below embodiment is to invention has been detailed description by reference to the accompanying drawings, and those skilled in the art can make many variations example to the present invention according to the above description.Thus, some details in embodiment should not form limitation of the invention, the present invention by the scope that defines using appended claims as protection domain.
