Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a work scaffolding device for elevator construction, which is used for installing elevator equipment in an elevator hoistway.

[Technical background of the invention and its problems]

Generally, during elevator installation work, a work scaffold is constructed in the hoistway where the elevator cars go up and down, and based on this work scaffold, the guide rails that guide the elevator car and the elevators are installed on each floor. Work has been adopted to install parts related to lifting of equipment such as passenger cars, counterweights, etc.

Conventionally, when constructing a work scaffold, as shown in Fig. 1, a vertical scaffold is constructed by sequentially joining nine single pipes located at the corner of the hoistway a from the lowest end of the hoistway a. Four base members b (j) are erected, and a plurality of horizontal girder members C as supporting members and longitudinal girder members d as scaffolding members are used to assemble multiple INs in a grid shape at regular intervals between the vertical members b... The work scaffold e... The structure to be completely constructed is used, and the installation work is being carried out on the work scaffold e...

It is known that large items such as mechanical parts are unloaded through the I-way.

However, according to the technique of constructing the work scaffold e by installing the vertical members b in the hoistway a, the unloading path becomes narrow, so when carrying large goods and parts, ... is in the way and the vertical member b...
Each time the meeting is held, the work scaffold e... must be dismantled.

Moreover, this disassembly and restoration requires a considerable amount of time and effort, which is an obstacle to increasing the efficiency of installation work. Moreover, the installation of the vertical members b... obstructs the work, making work in the narrow hoistway a even more inconvenient. In addition, the work scaffold e... has poor stability because it is assembled to the vertical member b... whose lowest end is the supporting part, and it is likely to cause lateral sway during installation work, etc. There is a problem that it is dangerous.

Moreover, according to the above-mentioned technology, there is a problem in that a lot of work (including time) is required for the assembly, disassembly, and removal of the vertical ground members (b) other than the work scaffolding. The work efficiency required for scaffolding is not very good,
Moreover, it was very costly.

[Purpose of the invention]

This invention was made in view of the above circumstances, and its purpose is to maximize the unloading route, facilitate the installation of supplies and parts, and shorten the work related to work scaffolding. It is an object of the present invention to provide a work scaffolding device for elevator construction that can be easily carried out in a short time and is safe and cost-effective.

[Summary of the invention]

This invention constructs a work scaffold by constructing a plurality of support members via fixtures between opposing walls on the lower level side of the hoistway, and constructing a work scaffold by constructing a scaffold member on top of these support members. By arranging multiple stages of scaffolding all sequentially towards the upper floors of the hoistway,
The work scaffold can be constructed without using all the vertical members, which are factors that narrow the unloading road, reduce the workability of assembling, dismantling, and dismantling the work scaffolding, and reduce the installation workability, and increase the safety and cost. This is what we are trying to build.

[Embodiments of the invention]

The present invention will be described below based on an embodiment shown in the drawings. In FIG. 2, reference numeral 1 denotes a hoistway formed inside a building or the like, through which a platform (not shown) goes up and down, and an elevator-machine room 1a is provided in the upper part of this hoistway 1. Further, within the hoistway 1, a plurality of work scaffolding devices 2 are provided at regular intervals along the hoisting direction. These work scaffolding devices 2... all have the same structure, and to explain one of them, 3.3 in the figure is a mounting fixture having an L-shape or a U-shape, for example; For example, these angle members 3, 3 are anchor ports 4, 3, 3, 4, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 3, 3, 3, 3, 3, 3, 3, 3, such 3, 3, so 3, so 3, 3, 3, such 3, 3, 3, 3, such 3, 3, 3, such 4, 3, such that an anchor port 4.

Then, each wall surface 1b, a protruding portion -1E protruding from Jb.
Eh = p constitutes the support seat 5.5. Reference numeral 6 in the figure denotes a support member, for example, a cross beam member composed of a single tube with nine tubes, and a plurality of cross beam members 6, for example two, are provided over the space between the above-mentioned fixtures 3, 3. Each end of these crossbeam members 6, 6 is connected to a connector 6 as shown in FIG.
Connector 6a is connected to the support seats 5, 5 through a...
...It is fixed to each angle member 3.3 throughout. Scaffolding members, for example, plate-shaped longitudinal girder members 7 are installed in the form of two parallel girders on these cross beam members 6.6, thereby forming the entire work scaffold 8. Note that 9 is a safety net.

10 in the figure is a safety device, and this safety device 10 is made by fixing, for example, an angle material 11 as a fixture with an anchor port 12 as shown in FIG. 4 under the floor of the elevator machine room 1a. Gravel? . , 1. The main letter 14 is connected to the angle member 11 of 1 through the hanging fixture 13, and the letter 14 is suspended along the entire hoistway 1 to the lowest floor. When installing the safety line 14 to suspend from the top of the hoistway 1, first attach it to the lower side of the hoistway 1, that is, the sides of the opposing walls 1b and 7b on the lowest floor. 6 Anchor bolts 4 and 2 N angle pieces 3 each.
Fix it with... At this time, it goes without saying that each of the angle members 3... forms a pair and faces each other with the support seat 5... in a horizontal position. Next, the cross-beam members 6 are pulled across between the spaced apart and facing angle members 3, 3, and the ends of each cross-beam member 6 are connected to the angle members 3... with the connectors 6a... to form a single stage of scaffolding. after that,
A work scaffold 8 is constructed by arranging the vertical beam members 7, 7 in a grid pattern on the horizontal beam members 6, 6 and fixing them to the horizontal beam members 6, 6 using coupling tools (not shown), respectively. . Then, on the work scaffold 8 on the lowest floor, assemble the work scaffold 8 on the upper level side according to the work procedure described earlier, and thereafter repeat this work sequentially in the direction of the upper floor of the hoistway 1. By constructing a plurality of scaffolds 8, the entire hoistway 1 is covered with a scaffolding device 8.
...will be assembled. The safety device 10 used in conjunction with this will also be installed.

Thus, in the state where the construction of work scaffold 8-2 is completed,
As shown in FIG. 5, it is now possible to maximize the unloading path without using any of the vertical members that have conventionally been problematic for each building.

Therefore, when unloading large items (not shown) into the machine room 1a through the hoistway 1, the work scaffold 8
There is no need for the time-consuming work of modifying (dismantling) and expanding the ..., making it possible to carry out cargo unloading operations more efficiently.

Furthermore, since there are no vertical members that obstruct the work when installing the unloaded equipment, the work can be carried out by maximizing the use of all sections of hoistway 1, making it easier to carry out work within the narrow hoistway. It is possible to improve workability (including efficiency) at In addition, since the work scaffolds 8 are each independently fixed in the hoistway 1, a structure with excellent stability without lateral sway can be constructed, and the installation on the work scaffolds 8... The work is safe and the safety is excellent. Furthermore, since the number of vertical members is reduced, the assembly, disassembly, and removal work involved in implementing the work scaffolding device 2 becomes easier and faster due to the reduction in work man-hours and associated time, increasing the efficiency of construction. (including labor saving), and also has the effect of reducing costs as well as reducing the number of members.

In addition, elevator ties other than the above-mentioned embodiments! Of course, this invention can be applied to all models.

[Effects of the Invention] As explained above, according to the present invention, since the structure is such that multiple stages of work scaffolding are constructed independently within the hoistway, it is possible to secure the unloading path to the maximum extent possible, and also to reduce the construction work. In addition, installation work can be made more efficient and safer.

In addition, the structure is extremely simple compared to conventional ones, and there are advantages in reducing costs.
