The present invention relates to a method for managing the opening and closing operation of a building inspection opening using such a sealing structure and a set for sealing a building inspection opening suitable for creating such a sealing structure.

  Conventionally, building inspection openings such as wall inspection openings and ceiling inspection openings have been provided on the walls and ceilings of buildings such as buildings and stations to maintain, inspect and repair wiring and piping laid inside. It has been. An example of such a building inspection port is a ceiling inspection port as shown in FIG. FIG. 6 is a diagram illustrating a conventional means for closing a building inspection port, and is an explanatory diagram showing an outline of a state in which a ceiling inspection port as a building inspection port is looked up from the indoor side. The ceiling inspection port 1 shown in FIG. 6 includes a rectangular outer frame 4 fitted in and attached to an inspection opening 3 established on the ceiling surface 2, and an inner frame that fits inside the outer frame 4. 5 and a lid 6 attached to the inner frame 5, the inner frame 5 is attached to the outer frame 4 so as to be pivotable on one side, and the inner frame 5 is located inside the outer frame 4. The lock means 7 for holding the fitted state, in other words, the state in which the inspection port 1 is closed by the lid body 6 attached to the inner frame 5 is opposed to one side where the above-mentioned rotation is connected. It is provided on the side. As such a locking means 7, for example, as shown in FIG. 3 to be described later, there is a locking claw 7b rotatably attached to the inner frame 5 by a lock shaft 7a. As shown, a groove 7e that can be operated with a coin or a screwdriver is formed on the lower surface 7c of the lock shaft 7a, and the claw is engaged from the front side (below the ceiling) with the lid 6 closed using a coin or screwdriver. 7b can be rotated and locked to the outer frame 4 so that the closed state of the inspection port 1 by the lid 6 can be maintained, or the locking claw 7b can be removed from the outer frame 4 to release the lock. The means comprised in (1) is mentioned. In addition, at the wall inspection port, for example, a Maggnet is attached to the inner frame side, a steel plate is attached to the outer frame side, and the closed state of the inspection port by the lid material is maintained using the adsorption force of the magnet to the steel plate. There are means. However, with such a lock means, the lock is easily released, and there is a possibility that the locking claw may move and the lock may be released due to vibration caused by an earthquake or the passage of a train. There are problems, and various proposals have been made to solve such problems.

  For example, Patent Document 1 discloses that the inspection palate is slid by sliding the inspection palate as an inspection port of a building wall in which the inspection palate is easy to attach and detach and is not easily detached in the event of vibration such as an earthquake. It has an insertion engagement structure that engages with one side of the inspection port frame, and the other side of the inspection port lid is a structure that is engaged with the inspection port frame by a so-called push-push type catch device. The inspection lid can be attached to the inspection mouth frame by simply sliding one side to the one side of the inspection mouth frame and pressing the other side of the inspection mouth lid. It can be removed from the inspection port frame with a simple operation, and the base end of the engagement rod is attached in a manner having play in the mounting hole provided in the inspection port lid.

A set for sealing an inspection opening for a building characterized by comprising: In the present invention, the “front side” means the indoor side, the ceiling surface side if the building inspection port is a ceiling inspection port, the indoor side, the wall surface side, if the building inspection port is a wall inspection port, If the building inspection port is the floor inspection port, it is the indoor side and the floor side. If the building inspection port is the ceiling inspection port, the inside of the ceiling, the back of the ceiling, and the building inspection port are If it is a wall inspection port, the inside of the wall, the back side of the wall, and if the building inspection port is a floor inspection port, it is the lower floor side.

  That is, the present invention was made from a completely different viewpoint than the above-mentioned prior art building inspection port, and the opening of the building inspection port was sealed with the lid closed, and the inspection port was opened and closed. The present invention relates to a technology that has not been proposed in the conventional inspection port for buildings, and according to the configuration of the sealing structure for a building inspection port described in (1) of the present invention, the building in a closed state In the inspection port, the first clamping plate material disposed so as to straddle the back side flange of the outer frame and the back side flange of the inner frame, and the straddle straddling the front side flange of the outer frame and the front side flange of the inner frame. The second clamping plate material is locked so that the head portion cannot pass through the insertion hole of the first clamping plate material, and the free end side of the band portion passes through the gap between the outer frame and the inner frame from the insertion hole. The surface of the second clamping plate inserted through the band guide hole It is connected by the band member engaged in the engagement hole of the arranged block body so as not to be reversely removed, in other words, by the first sandwiching plate member and the second sandwiching plate member connected by the band member as described above. Since the flange of the outer frame of the opening of the inspection opening for the building at the installation location of the sealing structure and the flange of the inner frame of the lid that is in contact with this are sandwiched from the back side and the front side, Unless the sealing structure is destroyed, the lid cannot be opened to open the inspection port. Therefore, even if the opening of this inspection port is closed again with the lid, the attached sealing structure is destroyed, so it cannot be sealed again with this sealing structure, and the inspection that was closed It can be visually recognized immediately that the mouth has been opened. And, the sealing structure of the present invention does not require opening a hole in the building inspection port when sealing the building inspection port, and the existing building inspection port provided with such an outer frame and an inner frame. Even so, it can be sealed as it is.

Here, the seal structure of the building inspection port according to the present invention is further separated from the second sandwiching plate member or the first sandwiching plate member, and a symbol, character and / or identifying the second sandwiching plate member or the first sandwiching plate member. If it is equipped with a numbered notation plate, work must be done when the sealing structure is destroyed and the inspection port is opened, or when the closed inspection port is sealed again with a new sealing structure. It can be used as a copy of the information that identifies the inspection port to be performed. By specifying the inspection port that performs the work in this way, it is possible to confirm the presence or absence of the inspection port opened by outsiders or vibrations. Also, maintenance and inspection work can be confirmed and managed. Note that the notation plate material is separated from the second clamping plate material when the first clamping plate material has a bent portion as described later, or when the first clamping plate material is reused, More preferred. Furthermore, when the same sign, character and / or number as the notation plate material is described on the second sandwich plate material or the first sandwich plate material, for example, as described later, management of opening / closing operation of the building inspection port according to the present invention After confirming and managing the inspection port that opened and closed the inspection port by the method, after destroying the sealing structure, bring the indicated second clamping plate material to the administrator, etc., to destroy the sealing structure It is possible to identify and manage the inspection port. When the one in which the tip of the free end side of the second holding plate material band member protruding to the front side from the block body has been removed, a situation such as look better from the front side, also, is mischievous pulling Can be suppressed. If the first sandwiching plate material is fixed to the outer frame, the first sandwiching plate material can be easily handled when a sealing structure is manufactured as described later. Furthermore, the outer frame includes a rising plate portion that rises higher than the height of the opening (thickness of the ceiling surface, wall, etc.) from the front flange along the peripheral surface (peripheral wall) of the opening, It has a rising plate portion that rises from the front side flange along the peripheral surface (peripheral wall) of the lid body, which is higher than the height of the lid body. In other words, each back flange is from the back of the ceiling, the back of the wall, etc. If it is spaced apart from the back side, the flat part straddling the back side flange of the outer frame and the back side flange of the inner frame fitted to the outer frame, and the outside of the flat part It is provided with a bent portion bent toward the front from the end on the frame side, or the tip surface of the bent portion is an inclined surface inclined to the front from the outer surface side toward the rising plate portion, Furthermore, the first clamping plate material is bent from the end on the inner frame side of the flat portion toward the front side. Even if the bent portion on the inner frame side is bent so that it is inclined obliquely outward with respect to the rising plate portion of the inner frame, the sealing structure will be described later. It becomes easy to handle the first sandwiching plate material when manufacturing.

  Further, the sealing structure of the building inspection port according to the present invention is not particularly limited in the type of the building inspection port to be sealed, and is applied to, for example, a ceiling inspection port, a wall inspection port, a floor inspection port, etc. However, in consideration of the fact that the block body of the second clamping plate protrudes to the front side, it is more suitable when applied to a ceiling inspection port and a wall inspection port. Here, in the case of the present invention, the structure of the inspection opening for buildings to be sealed is not particularly limited, and the position to be formed is not particularly limited. For example, the inspection opening for buildings is a lid. If the lock means for holding the closed state is provided, if the sealing structure of the building inspection port is formed in the vicinity of the lock means, the work of releasing the seal and opening it becomes easy. . Furthermore, as described above, the sealing structure for a building inspection port according to the present invention can be formed on an existing building inspection port. For example, the sealing inspection port is either an outer frame or an inner frame flange. Or, a building inspection port that does not have all, more specifically, an inspection port that does not have one or both of an outer frame and an inner frame, an outer frame, and an inner frame, but is provided. If the outer frame and the inner frame are inspection ports that do not have one or both of the back side flange and the front side flange, as described above, the first holding plate material and the second holding plate material are connected to the respective back side flanges of the outer frame and the inner frame. In addition to the flange that does not exist, the first sandwiching plate material and the second sandwiching plate material in the vicinity of the edge portion of the opening and the vicinity of the edge portion of the lid body can be used. In other words, for example, with a flange In the inspection port that is not present, the first clamping plate material is disposed so as to extend around the periphery of the opening edge on the back side of the opening of the inspection port and the edge on the back side of the lid opposite thereto, and the second clamping plate material It can be set as the aspect arrange | positioned so that the front side edge part vicinity of the opening part of an inspection port and the front side edge part vicinity of a cover body may be straddled.

  And according to the said structure of the management method of the opening / closing operation | work of the inspection opening for buildings as described in said (2) of this invention, when destroying the sealing structure of the inspection opening for buildings of this invention, and opening an inspection opening Confirming that the inspection opening is opened with the information for identifying the inspection opening for the building closed, the opening of the inspection opening after the inspection work is closed again with the lid, and the above-mentioned set for resealing and destruction When the building inspection port is sealed again using the first sandwiching plate member or the new first clamping plate member having the sealed structure, the building inspection port is blocked with the information for identifying the building inspection port being refrained. Since it is confirmed and managed that the seal has been sealed, the building manager can manage whether or not a particular building inspection port has been opened or closed, and the blocked inspection port can be controlled by an outsider. When an opening occurs due to vibration or vibration It is possible to visually recognize immediately such a situation. The re-sealing set is intended to reuse the destroyed first sandwich plate material with a sealed structure. If the first sandwich plate material is not reused, a new first sandwich plate material should be prepared. Can do. In addition, the block body may be fixed in advance at a predetermined position of the second sandwich plate material, and is prepared as a separate body, and when the sealing structure is formed, the band member is used to form the predetermined second sandwich plate material. It may be configured to be brought into contact with the position, but if it is fixed in advance at a predetermined position of the second clamping plate material, it becomes easier to determine that the inspection port has been opened, More preferred. Here, the second sandwiching plate material of the set for re-sealing can be separated from the plate material main body, and a symbol, character and / or number identifying a predetermined building inspection port is described or can be described A sign, character, and / or number written on the sign board is removed by separating the sign board from the second sandwich plate of the re-sealing set that is provided when the building inspection port is opened. Is used as information for identifying the building inspection port, the identification operation of the building inspection port that has performed the opening operation and the closing operation becomes easy and reliable. Furthermore, the same sign, character and / or number as the notation plate material is described in the plate material body of the second sandwich plate material, and when the building inspection port where the plate material body is resealed is opened again, the building inspection More specifically, for example, when confirming and managing the next opening / closing operation of the inspection opening for the building, after destroying the sealing structure, the second holding plate material is used for the building. By handing it over to the manager, etc., it is possible to keep a record of the opening of the building inspection opening.

  And according to the sealing set for a building inspection port described in the above (3) of the present invention, it comprises the first sandwiching plate material and the second sandwiching plate material constituting the sealing structure of the building inspection port of the present invention, and Since the band member for sealing constituting the band member is provided, the first sandwiching plate member and the second sandwiching plate member are disposed at predetermined positions of the building inspection port closed by the lid, and the sealing band member By linking these together, the building inspection port sealing structure of the present invention for sealing the target building inspection port can be produced. Here, in the set for sealing a building inspection port according to the present invention, the second sandwiching plate member or the first sandwiching plate member is detachable from the plate member main body and identifies the second sandwiching plate member or the first sandwiching plate member For example, when handing out the sealing set of the present invention to a worker, if the character and / or number is described or provided with a description plate that can be described, work is performed by removing the label plate The inspection port that is used as a copy of the information that identifies the inspection port to be used, or when the worker creates a sealing structure in the inspection port blocked by the sealing set of the present invention, with the marking plate removed and sealed. It can be used as a refusal for specific reporting. In addition, it is more suitable that the board | plate material for description is provided in the 2nd clamping board | plate material similarly to the sealing structure mentioned above. In addition, if the same symbol, character and / or number as the notation plate material is written on the plate body of the second sandwich plate material or the first sandwich plate material, the opening / closing operation of the inspection port is confirmed and managed as described above. This is more preferable. Further, the first sandwich plate has a substantially L-shaped side surface, and the insertion hole is formed on any one of the plate surfaces forming the substantially L-shaped side surface, or the substantially side-shaped side surface. It has a shape, and the insertion hole is opened on any one plate surface forming a substantially square shape on the side surface, and the other plate at the end of one plate surface on which the insertion hole is opened With a bent portion facing the surface, or with the tip surface of the bent portion inclined on the outer surface side, in other words, the inclined surface with the tip surface inclined obliquely downward from the outer surface side toward the inner surface side If it is formed so as to be a surface, as will be described later, when the sealing structure of the present invention is produced in the inspection port of the type provided with the outer frame at the opening by the sealing set of the present invention, the first is used. The sandwich plate material is easy to handle.

  According to the present invention, it is possible to immediately visually recognize that the inspection port that has been closed is opened, and it is easy for a building manager or the like to confirm and manage whether or not it has been opened by some people. It can be installed on the outside of buildings and facilities, such as entrances to buildings and apartment buildings, and entrances to buildings where people can freely enter and exit, such as public facilities. It is possible to check and manage the opening and closing state of a building inspection port even if it is located in such a place. For example, it is easy to prevent tampering and counter terrorism at the building inspection port. It became possible to do. In addition, it is easy to release the seal when opening the inspection port during maintenance and inspection, and to install the seal structure after closing, and there is little need to pay attention to management like a key. Furthermore, it has become possible to suppress the occurrence of a situation in which the inspection port is unlocked and opened due to vibration caused by an earthquake or the passage of a train.
