Description

Building cleaning rope fixture {.

In order to fix a rope hanging on a building to a building, the reinforcing bar fastening member is rotated to easily fasten the reinforcing bar to the reinforcing bar to clean the outer wall surface of a glass window or tile of a high-rise building. It is possible to securely secure the safety of the cleaning worker on the outer wall surface of the building using the rope. And more particularly to a rope fixing device for cleaning buildings.

Generally, when cleaning the outer wall of a high-rise building, an operator hangs on the rope and cleans the roof from the top of the building. At this time, the rope must be fixed to the top of the building to fix the rope, Respectively. Therefore, it is necessary to fix the rope on the top floor of the building. In recent buildings, the rope fixing ring is embedded in the concrete when the railing of the building is formed. On the other hand, the rope fixing device must be firmly mounted on the wall of the building, since it can safely support the person hanging on the rope. Therefore, the rope fixing device for building cleaning is usually constructed by fixing the rope fixing device to a steel frame or a reinforcing bar which is installed inside a wall of a building when building the building, and then a reinforcing bar for reinforcing the wall of the building when the concrete is laid, To be buried in the wall surface, thereby providing a safe and durable installation structure. That is, in order to install the high-rise building cleaning rope fixing device, when the concrete on the outer wall or the column of the building is poured, the portion where the rope is held is exposed to the outer wall surface of the building and the rest is tied to the reinforcing bar in the building wall It is being buried.

When the curing of the concrete placed between the dies 12 is completed, the dies 12 on both sides are removed. At this time, the dies 12 provided with the rope rings 7 can not be removed due to the rope loop 7, Another large hole 18 is formed in a portion where the rope loop 7 is located to remove the mold 12. The mold 12 having the holes 18 formed therein can not be reused, and therefore can not be disposed of. Especially in case of recently used molds of steel plate, the price is high and the economic loss is great. Since 5 to 20 rings are usually installed in a single building, about 5 or as many as 20 molds are disposed of, resulting in a large economic loss. Since the fixing pieces 6 of the rope loop 7 are inserted into the through holes 17 formed in the formwork 12, movement occurs in the rope loop 7 when the concrete is laid, There is a problem that the position is changed.

A rope loop 7 is fastened to a rope at the front end of the fixing piece 6. An auxiliary reinforcing bar 8 disposed inside the wall of the building is inserted into the rear end of the fixing piece 6 to be fixed And a reinforcing bar insertion hole 9 is formed. 2B, the auxiliary reinforcing bars 8 are horizontally inserted into the reinforcing bar insertion holes 9 formed in the fixing pieces 6, And then the concrete is laid. However, it is necessary to cut the auxiliary reinforcing bar 8 at the time of construction and transfer it to a high place, and to insert the auxiliary reinforcing bar 8 into the reinforcing bar insertion hole 9 and then to bundle it with the wire 16 The reinforcing bar insertion hole 9 and the reinforcing bars 14 and 15 are often bundled with the wire 16 without using the auxiliary reinforcing bar 8 at the actual construction site in many cases. However, in reality, the fixing pieces 6 are not firmly fixed to the reinforcing bars in the building structure and are not fixed to the walls or pillars of the building. In this case, Which is not supported by the cement portion of the concrete, is insufficient in structural strength and thus can not guarantee safety. In addition, the above-described structure has a problem that it is relatively expensive because it takes a lot of time for assembling components and constructing them at a high construction site.
