JP2017137645A - Lock control method for wiring room before handover - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a lock management method that does not use a permanently provided key, instead of a management method using a key of a permanently installed door handed over to a client while being attached to the permanently installed door, for eliminating a risk of loss or duplication of the key during construction work of the building.SOLUTION: In a lock management method for a wiring room before handover, an end 31 of a wire 1 having a ring formed on both ends is engaged on a structure 5 inside the wiring room, and the other end 32 is locked on a door knob 6 on an indoor side of the wiring room using a padlock 7. While being locked, the wire 1 has a length to form a gap that allows the padlock 7 on the indoor side to be accessed when a door 4 of the wiring room is opened from outside, but does not allow a person to enter the wiring room.SELECTED DRAWING: Figure 2

Description

The present invention relates to lock management using a wire and a padlock without using a key even when a permanent key is attached to a permanent door.

In a building, a space that is divided in order to intensively pass electrical equipment trunks such as cables and piping wiring is called an electric pipe shaft (abbreviated as EPS), also called a wiring room. EPS is equipped with distribution boards and terminal boards through cables and piping.
Conventionally, after the main power is received during construction of the building, the main door is locked and managed with the main key in order to prevent EPS electric shock.
When locking with the main key, locking will be managed using the key handed over to the customer, and in the case of EPS, it will be lent out to an electrician who enters after receiving the power.
Even with careful management, the risk of being lost or duplicated remains.
Even if you make a loan or pledge, the risk remains. One of the methods is not to lend keys and all are managed by the main contractor, but it is inefficient from the viewpoint of time reduction, and there is still a risk of loss.
Instead, there is a method of using a temporary lock, but since the quantity increases at a large-scale site, a temporary lock cost is incurred.

Japanese Utility Model Publication No. 54-24958

It is an object of the present invention to develop a method for locking management without using a key even when a permanent key is attached to a permanent door.

According to the first aspect of the present invention, one end of a wire having a ring formed at both ends is locked to a wiring chamber structure, and the other end is locked to a door knob on the wiring chamber side with a padlock. It is a management method.

According to the second aspect of the present invention, when the wire is locked, the wire is a gap that allows access to the indoor padlock when the door of the wiring chamber is opened from the outside, and is a length that is a gap that prevents a person from entering the room. The wiring room locking management method according to claim 1, further comprising:

Invention of Claim 3 is the wire used for the wiring room locking management method described in Claim 1 or Claim 2, Comprising: When the door is opened in the locked state in which a ring body is formed at both ends It is a wire for locking a wiring that has a length that allows access to a padlock and a space that allows a person to enter the room.

The present invention realizes locking management without using a permanent key by using a wire having a ring formed at both ends and a padlock.
In addition, there is a cost advantage over provision of a temporary key on the door, and the labor of management by lending a permanent key is reduced, which contributes to a reduction in time.
In addition, since the main key can be handed over to the owner in an unused state, the safety of the owner is improved.

FIG. 1 shows a tool used in this embodiment.
A wire 1 and a padlock 7 having ring portions 3 formed at both ends.
The wire 1 has a predetermined length (for example, about 300 mm), and is provided with an elliptical ring portion 3 at both ends, bent at both ends inwardly and fixed at the root by a metal fitting 2 such as an aluminum sleeve.
A padlock that is generally used is used.

FIG. 2 shows the locked state from the inside of the EPS room.
The door frame is fixed from the floor or the ceiling of the cabinet, and the door frame and the open / close door 4 are fixed by a hinge.
A main key 8 is provided at a position slightly higher than the middle on the right side of the open / close door inner surface 41 of the open / close door 4, and a door knob 6 is provided therebelow.
Since EPS often does not have an internal wallboard, light gauge steel (light gauge steel: LGS for short) often appears.
One end of the wire 1 is locked to the small opening of the lightweight steel frame, or the wire 5 is fixed to a fixed object 5 such as a steel frame projection on the inner surface 41 of the open / close door 4 when viewed from inside the EPS. One end of 1 is locked.
As a locking method, the wire 1 is wound around a fixed object 5 or the like, and is passed through the ring portion 31 at one end so as not to come off.
The ring portion 32 at the other end of the wire 1 is locked to the door knob 6 of the door 4 with a padlock 7. Since the EPS door knob 6 has a ring shape, the ring portion 32 of the wire 1 and the ring of the door knob 6 can be connected by a padlock 7.
The permanent key 8 of the open / close door 4 is not locked, and the key 8 is always unlocked.

FIG. 3 shows an enlarged view of the locked state.
By fixing the door frame from the floor or the ceiling of the cabinet and fixing the door frame and the opening / closing door 4 with a hinge, the opening / closing door 4 can be opened and closed so that the person cannot enter the opening / closing door 4 so that the ring 31 at one end of the wire 1 is not The other end 32 of the wire 1 is wound around the fixed object 5 in the EPS and fixed to the door knob 6 provided on the inner surface 41 of the opening / closing door by the padlock 7.
When opening and closing the opening / closing door 4 from the outside of the EPS, the ring 31 at one end of the wire 1 is wound around the fixed object 5 within the EPS, and the ring 32 at the other end of the one wire 1 is connected to the inner surface 41 of the opening / closing door. Since the wire 1 is tensioned and fixed to the door knob 6 provided by the padlock 7 so that the hand 1 can enter, it is in a state in which humans cannot enter.
To enter the EPS, with the door 4 opened halfway, manually unlock the padlock 7, disconnect the wire 1 and the door knob 6, open the door 4 fully, You can enter the room.
Further, when locking out after leaving the EPS, the fixed object 5 is wrapped around the ring 31 at one end of the wire 1 again so as not to come off, and the other end 32 of the wire 1 is connected to the open / close door 4. The door knob 6 is locked with a padlock 7 and the door 4 is closed.

FIG. 4 shows the door opening state in the locked state. FIG. 5 is a plan view thereof.
It can be opened and closed by fixing the door frame from the floor or the ceiling of the cabinet, and fixing the door frame and the open / close door 4 with a hinge. The door knob 6 is opened, and a gap S is formed so that humans cannot enter but the hand can be put in and the padlock 7 can be operated. A ring portion 31 at one end of the wire 1 is wound around a fixed object 5 in the EPS, and the other end 32 of the wire 1 is fixed to a door knob 6 provided on an inner surface 41 of the opening / closing door by a padlock 7.
The gap S of the door 4 is adjusted so that the length of the wire 1 is adjusted so that humans cannot enter the EPS, so that the EPS before delivery is substantially locked. Yes.
