The specific embodiment
Below in conjunction with accompanying drawing the structure of elevator shaft of the present invention from steady operating platform is elaborated.
Referring to Fig. 1 and Fig. 2, the whole height of the certainly steady operating platform of this elevator shaft is suitable with the height of floor, so that the construction successively of elevator shaft template, it is a double-decker, comprise: upper platform and lower floor's platform, upper platform is made up of upper platform support 1 and the scaffold floor 9 that is laid on the upper platform support 1, and lower floor's platform is made up of lower floor's platform support 2 and the scaffold floor (not shown) that is laid on lower floor's platform support 2.Below upper platform 1, be provided with longitudinal bracing frame 4 ', below upper platform 1, be provided with diagonal brace support 3 away from elevator door one side near elevator door one side.Upper platform provides operating surface for the elevator shaft structure construction, and lower floor's platform is used to place small-sized construction machinery 11, for example electric welding machine, air compressor etc.Upper platform is square, its area is slightly less than the cross-sectional area of elevator shaft, the area of lower floor's platform is less than upper platform, lower floor's platform is positioned at same vertical plane near the respective side of elevator door one side and upper platform, on the diagonal brace support 3, following two ends are separately fixed at, lower floor's platform is away from a side of elevator door, be provided with the right angle type supporting leg 4 at the wallboard external corner place, bottom that is used to be stuck in the elevator doorway near elevator door one side at lower floor's platform, near four jiaos of upper platform, respectively be provided with suspension ring, wherein near the height of two suspension ring 7 of elevator door one side greater than height away from two suspension ring 8 of elevator door one side.Downward part vertical in the right angle type supporting leg 4 can be extended to form downwards by longitudinal bracing frame 4 '.
This platform is not established at upper platform under the situation of the strong point, can carry out stable support by upper platform and right angle type supporting leg, realizes from steady.When whole platform is sling, when the top of each suspension ring is positioned at sustained height, right angle type supporting leg 4 can all be positioned at elevator shaft (referring to Fig. 4), thereby can finish the lifting of platform smoothly.
In order to improve safety, below the arbitrarily relative both sides of upper platform, also be provided with the support member 6 that is fixed on the elevator shaft wall, is used to support upper platform, in the present embodiment, each evenly is provided with 2 to support member 6 in described relative both sides.
In addition, drop, around lower floor's platform 2, also be provided with protective guard 10, preferably, on protective guard 10, install the protective screening (not shown) additional in order to prevent the construction equipment that is placed on lower floor's platform 2.
Can the aforesaid operations platform be realized installing with lifting smoothly in elevator shaft depending on following six technical datas:
1, the height of the low suspension ring 8 in left side;
2, the distance of the outer side edges of the higher suspension ring 7 in right side and elevator shaft body of wall;
3, the difference in height of both sides suspension ring;
4, the distance of upper platform outer side edges and elevator shaft body of wall;
5, upper and lower layer platform connects the angle of diagonal brace 3;
6, lower floor's platform legs 4 puts in the size on elevator doorway.
Figure 3 shows that a specific embodiment of the present invention, as shown in the figure, upper and lower layer platform all adopts 10# channel-section steel welding spelling, all is being covered with the thick scaffold floor of 50mm 9 (scaffold floor on lower floor's platform 2 is not shown) on the levels platform.Platform in the present embodiment is pressed headroom size 2200 * 2200mm, floor height 2900mm design in the elevator shaft, and the parameter value of above-mentioned six parameters is respectively: the height of left side suspension ring 8 is 130mm; The distance of the outer side edges of right side suspension ring 7 and elevator shaft body of wall is 250mm; The difference in height of both sides suspension ring is 250mm (that is: 380mm-130mm); The distance of upper platform outer side edges and elevator shaft body of wall is 50mm; The angle that upper and lower layer platform connects diagonal brace 3 is 70 °; Lower floor's platform legs 4 puts in the elevator doorway and is of a size of 300mm.
These six parameter values are complementary, if a parameter changes, then need adjust all the other parameter values, otherwise platform can't be realized lifting smoothly and promote.Take to define earlier parameter 1 (130mm) in six parameters, parameter 4 (50mm), parameter 5 (70 degree), parameter 6 (300mm) in the present embodiment, all the other two parameters (parameter 2, parameter 3) can be determined by the rotate command demonstration of AutoCAD software.
Be different from this accompanying drawing as elevator shaft size and floor height, need to draw the AutoCAD operation drawing in proportion earlier according to corresponding size, after tentatively completing, by the AutoCAD rotate command installation, lifting process are demonstrated, as meeting any position collision of platform elevator shaft inwall in the presentation process, then need above-mentioned six parameter values of corresponding adjustment, install, promote and can realize function of use and certainly steady function smoothly until platform.
Below in conjunction with Fig. 4 the lifting process of operating platform of the present invention is described.
As shown in the figure, the lifting rope of tower crane is fastened respectively on 4 suspension ring, the length of lifting rope is identical owing to the rings height difference of both sides, so two highly low suspension ring 7 are raised earlier, operating platform is tilted, make right angle type supporting leg 4 enter in the elevator shaft fully, at this moment, upwards spur lifting rope, operating platform is promoted in the elevator hoistways that last layer completed, manually operating platform is pulled to level, make right angle type supporting leg 4 be stuck in the wallboard external corner place, bottom on elevator doorway, unclamp lifting rope then, upper platform just is resisted against on the wall of elevator shaft away from a side of right angle type supporting leg 4, because the right angle type supporting leg 4 on lower floor's platform has been stuck in the external corner place of elevator doorway lower walls plate, thereby whole platform is in equilibrium state.For greater safety, gib headed bolt or other support member can also be set below upper platform, support member be inserted in the preformed hole on the elevator shaft wall and fixing.After construction finishes, pull down support member, can continue to promote this operating platform by above-mentioned steps.
