Abstract

PURPOSE:To secure the economical efficiency and safety in reform by temporarily placing a fence which is withdrawn to a position in close to a construction site during the process of constrcution and returning a fence which is temporarily placed when construction is suspended, to the former place, and temporarily fixing the fence. CONSTITUTION:A scaffolding 2 is assembled to the outside of a fence 1, and a stay 6 for the fence 1 is cut at the position far by a prescribed depth from the upper surface of a fixing concrete 7, and the fence 1 is lifted up and laid on the supporting arm 3 of the scaffolding 2, and suspension-fixed at a proper position. Then, a proper place on the upper surface of the concrete 7 is core-cut to form a stay hole 8, and the lower edge of the stay 6 for the new fence 1 is inserted into the hole 8, and after position correction, the hole 8 is charged with mortar 9. When construction is suspended, the old fence 1 is returned to the old position, and the lower edge part of the stay 6 is inserted into the hole of the concrete 7, and the upper edge is fixed on the arm 3, and the fence 1 is temporarily fixed. Accordingly, the old fence 1 is positioned at the scaffolding 2, and the necessity of the closing by other temporary member is obviated, and the economic efficiency and safety in reform can be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reforming fences and the like for the purpose of ensuring workability, economy and safety of reforming fences and the like.

[0002]

2. Description of the Related Art Conventionally, when remodeling a fence or the like, artificial work is performed so that the same place can be completed in one day. Therefore, even a relatively short fence must be constructed by a plurality of people.

Further, when the construction is carried out for more than 2 days, another material is used in order to prevent the danger and to block the place where the fence is left when the construction is interrupted.

[0004]

According to the above-mentioned conventional construction method, it is necessary to use another temporary member instead of the fence or the like to be remodeled when the construction is interrupted, and to close the portion. It was difficult to use it (for example, to dry the futon) because it was a blocking material to prevent the passage.

Further, when the construction site is at a high position, there is no appropriate means for preventing danger, and special measures (scaffolding) are required.

In addition to the above, in order to finish the construction in one day,
It was difficult to perform efficient sequential construction (cross-processing across multiple sites for each type of work), as it was often necessary for intensive construction by more than the required number of workers.

[0007]

However, according to the present invention, the old fence to be removed is temporarily fixed to the place to be remodeled when the construction is interrupted, so that the construction may take a plurality of days or a separate member may not be used. In addition, since it can be used for a temporary fixed fence or the like and for prevention of danger, the above-mentioned conventional problems are solved.

For example, when construction is interrupted, the old fence is temporarily fixed to the old position to close the part, so that it is not necessary to use other members and the futon or the like can be dried to prevent danger. Can be used as well. Therefore, even if the construction work is interrupted for several days, neither inconvenience nor danger will occur. Moreover, if the old fence is temporarily installed on the scaffolding side, it will be the same as when the protection member is installed on the scaffolding from the side of the balcony, and it is expected to have a risk prevention effect not only psychologically but also practically. be able to.

That is, the present invention cuts off a fence or the like to be removed, and then temporarily puts it at a position close to the construction site during construction, and when the construction is interrupted, returns the temporarily put fence to the old position and temporarily fixes it to a new fence or the like. It is a method of reforming fences, etc., which is characterized by removing the old fence after installation. In another invention, fences to be removed are temporarily placed on a scaffold installed at a construction site, and when temporarily fixed to an old position, a part of the fence is temporarily attached to a constituent material of the scaffold. The lower part of the pillar of the old fence is designed to be cut at a position that is a predetermined depth from the surface of the embedded concrete.

The present invention can be applied not only to fences, but also to partition fences of various shapes, handrails, and other reforms of properties consisting of columns and stopper members arranged between the columns.

The construction method of the present invention is not limited to the material of the fence or the like, and can be applied to all materials conventionally used.

[0012]

According to the construction method of the present invention, the position of the old fence can be easily closed when construction is interrupted. Therefore, when the construction is continuously carried out for several days, of course, even when the construction is continued with interruption, there is no concern about safety and danger.

Further, since the same type of work can be intensively performed in the construction, the efficiency is very good, and of course, it is not necessary to intensively use a large number of workers at one site, and workability is remarkably improved. You can

[Example] Scaffolding 2 outside the fence 1 to be remodeled
Assemble. On the scaffold 2, the support arm 3 is extended in the horizontal direction (direction of the veranda 4) in order to mount the fence 1. Next, the support pillars 6 of the fence 1 are cut at a position where they enter a predetermined depth (for example, 2 cm) from the upper surface of the concrete wall 7. After the fence 1 is cut off from the concrete concrete 7 in this way, the fence 1 is lifted and hung on the support arm 3 and fixed by hanging it at a proper position (a position where it does not interfere with core removal, etc.) (FIG. 1, FIG. (Dashed line shown).

Next, the core of the proper place on the top surface of the concrete 7 (the position where the pillar of the new fence is filled) is removed, and the pillar hole 8 is formed.
To provide. To temporarily place the old fence 1, the old fence 1 is returned to the old position, and the tip portion of the support arm 3 and the old fence 1 are bound and fixed. If necessary, the temporary fixing material 5 can also be used.

For example, in a housing complex, when renovation is required at different places in the same building, construction is performed simultaneously at a plurality of places. For example, the pillars 6 are cut by sequentially cutting the pillars 6 at a plurality of locations, and then core removal is also performed sequentially. For example, A, B, C on the 2nd floor, D on the 3rd floor,
If there are E and F sites, core removal is A, B,
Dedicated questions by sequentially rotating C, D, E, and F. If this is done, the work will be rational, but the first day of construction will be completed halfway at each site.

However, a few days later, A, B, C, D, E,
The location of F will be completed at the same time. According to the above, each site is interrupted, but at the time of interruption, the old fence is returned to the old position, the lower end of the pillar is put in the hole (hole when cutting) of the concrete wall 7, and the upper end of the pillar is fixed to the support arm 3. ,
This means that the temporary fixing of the fence 1 has been securely performed.

When the core removal is completed as described above, the lower end of the pillar 6 of the new fence 1 is inserted into the pillar hole 8 by the core removal to correct the position, and then the mortar 9 is inserted into the gap of the pillar hole 8. Complete the work by filling. Therefore, the old fence 1 and scaffold 2 are removed.

In the above, if the old fence 1 is suspended and fixed to a proper place of the scaffold 2, it is possible to ensure the safety of the worker when working on the balcony side.

[0020]

That is, according to the present invention, since the old fence is temporarily placed on the scaffold, there is an effect of preventing the worker from danger. Also, when the work is interrupted, the old fence is returned to the old position, the scaffolding and the old fence are fixed, and the old fence is temporarily fixed, so it is also possible to use the old fence to dry the futon when the construction is interrupted, and it falls from the veranda. This has the effect of preventing the possibility of
