Description

  The present invention relates to a cutting technique for processing a building member such as a folded plate roof without removing asbestos such as asbestos felt heat insulating material.

Patent Document 1 discloses a method of treating a folded roof without removing the asbestos felt heat insulating material of the folded plate roof using the asbestos felt heat insulating material. In the cutting process of Patent Document 1, for example, the specification [0014] discloses that “cutting with plasma is good”. In addition, there is a method of cutting by moving the blade many times before cutting, such as a saw.
JP 2006-43620 A

The technique by plasma fusing and gas fusing disclosed in Patent Document 1 is a cutting technique by thermal energy. However, since the material containing about 90% of asbestos is excellent in fire resistance, it is difficult to cut by heat energy. Therefore, such a fusing technique using heat energy has poor workability and handleability, and therefore has been a cause of poor work efficiency in the cutting process when processing a folded roof with an asbestos felt heat insulating material. That is, heat is generated and a flame is generated, so that the danger is high, and it is necessary to surround the working atmosphere with a non-combustible plate such as a calcium plate.
Furthermore, when an operator directly handles, there is a problem in that dust scattering cannot be minimized, and when a saw or the like is used, dust is easily scattered.

Therefore, in order to solve such a problem, the present inventor has completed the present invention having the following contents.
(1) The present invention is characterized by cutting a building member to which asbestos adheres, such as a folded roof with an asbestos felt heat insulating material, by a cutting machine.
(2) The construction member is inserted into a cutting machine so that the side to which the asbestos is attached is up.
(3) The shape of the cutting machine is matched with the shape of the building member root.
(4) The cutting machine has a pressing part that holds the building member and a cutting part that cuts the building member.
(5) The cutting machine has a stopper so that the building member is cut into a certain size.
(6) The pressing part and cutting part of the cutting machine are simultaneously lowered perpendicularly to the longitudinal direction of the building member, the holding part stops when it hits the building member, and only the cutting part further lowers and cuts the building member. And
(7) The cutting machine is characterized by having an enclosure in the cut portion and setting the inside of the enclosure to a negative pressure.
(8) The cutting machine has an operation button for moving the pressing portion and the cutting portion.

The present invention has the following effects.
(1) Since it is not a mechanism that uses thermal energy like fusing, it is not necessary to cover the work chamber with a non-combustible plate.
(2) Since it is safer and more workable than cutting by fusing and is configured to be cut only once the cutting machine is lowered, asbestos scattering can be prevented.
(3) Although it is necessary to slide a building member on a roof stand when inserting a building member into a cutting machine, since asbestos becomes an upper side, scattering of asbestos by friction can be prevented.
(4) It can cut efficiently by matching the shape of the cutting machine with the shape of the building member.
(5) By having the pressing portion, it can be cut efficiently with a small force. Thereby, the weight of the cutting machine itself can also be reduced in weight.
(6) It can be easily and efficiently cut to a certain size.
(7) By providing an enclosure and making the inside of the enclosure have a negative pressure, it is possible to further prevent asbestos from scattering.
(8) When the operation button is pushed, the cutting machine moves so that the safety can be confirmed before cutting.
(9) The work environment is improved by enclosing the cut portion and applying negative pressure, and the surrounding safety is ensured.

Embodiments of the present invention will be described with reference to the drawings. Here, the description will be given using “folded roof with asbestos felt heat insulating material” as a building member to be cut.
Drawing 1 is an explanatory view showing the condition of use of the cutting machine for building members concerning the invention in this application.
The folding roof 20 removed from the construction site by spraying “dust scattering agent” on the folding roof constructed at the site is carried into the cutting work booth 10.
The carried folding plate 20 is cut by a building material cutting machine 30 (hereinafter referred to as “cutting machine 30”) while moving on the insertion table 11 with the side 21 to which the asbestos felt heat insulating material is attached facing upward. Is. Here, since the folding roof 20 is moved in the cutting work booth 10 with the side to which the asbestos felt heat insulating material is attached facing upward, it is possible to prevent the asbestos from being scattered due to friction accompanying the movement.
And the cut piece (illustration omitted) by which the cutting process was carried out is packed severely, and is processed as an industrial waste.

FIG. 2 is a front view and a side view for explaining the cutting machine 30.
The cutting machine 30 includes a cutting space 40 that surrounds the folding roof to be cut, and a cutting means 50 that has a pressing portion that holds the inserted folding roof in the cutting space 40 and a cutting portion that cuts. Here, the cutting space 40 has an insertion port for inserting the folded plate roof to be cut and a discharge port for discharging the cut folded plate roof, but by making the inside of the cutting space 40 a negative pressure state, Asbestos can be prevented from being scattered from the insertion port and the discharge port due to cutting.
Reference numeral 60 denotes a hydraulic unit for supplying oil to a hydraulic cylinder for moving the cutting portion.

Next, FIG. 3 is an explanatory diagram for explaining a method for cutting the folded roof by the cutting machine 30.
The cutting means 50 included in the cutting machine 30 includes a pressing portion 51 that presses the folded plate roof 20 with contact surfaces 53 and 55 that coincide with each other between a non-movable fixed base 52 and a movable body 54 that moves. The cutting means 50 includes a cutting portion 56 that is movable in parallel with the movable body 54 and cuts the folded plate roof 20 with a cutting blade 57 that stops on the fixed base 52 side with respect to the contact surfaces 53 and 54. Yes.

FIG. 3A shows a state before the folded roof 20 is inserted into the cutting machine 30. The folded roof 20 is inserted with the side 21 to which the asbestos felt heat insulating material is attached facing upward. In addition, illustration of the cutting space (an insertion port and a discharge port) is abbreviate | omitted on account of description (Hereafter, it is the same in FIG.3 (b)-(d)).
FIG. 3B shows a state in which the folded roof 20 is inserted into the cutting machine 30. The folded roof 20 is inserted into a gap 59 formed between the fixed base 52 of the cutting machine 30 and the moving body 54. At this time, by providing the stopper 75 provided in the length adjusting guide 70, the insertion distance (dimension) of the folding roof 20 can be controlled to a fixed length, and the length of the cut piece to be cut is processed. The length can be made constant and the length can be freely adjusted.

FIG. 3C shows a state in which the folded roof 20 is pressed and cut. The pressing part 51 of the cutting machine 30 is a folded roof, because the movable body 54 that moves relative to the non-movable fixed base 52 is lowered and the contact surfaces 53 and 55 of both of them are located on both sides of the folded roof 20. Hold down 20. The cutting unit 56 of the cutting machine 30 cuts the folded plate roof 20 pressed by the pressing unit 51 with a cutting blade 57 that descends in parallel with the moving body 54. At this time, the cutting blade 57 can reliably cut the folded roof 20 by stopping on the fixed base 52 side (lower side) with respect to the contact surface 53 of the fixed base 52. Here, by moving (lowering) the movable body 54 and the cutting blade 57 in conjunction with each other, the cutting means 50 is configured to be cut only once lowered, so that asbestos can be prevented from scattering. Moreover, since the cutting | disconnection means 50 can be cut | disconnected after confirming safety by controlling by the operation button for moving the holding | suppressing part 51 and a cutting | disconnection part, safety | security improves.
FIG. 4D shows a state where the folded roof 20 is cut. The cut pieces 22 subjected to the cutting process are packed in a collection container (not shown), are strictly packed, and are processed as industrial waste. At this time, since the cut piece 22 is cut at a fixed length by the stopper 75, the work of filling the collection container can be performed easily and reliably. Note that the cutting machine 30 that has completed the cutting process returns to the original state (FIG. 3B) and performs the next cutting process.

  When the cutting machine 30 presses the folding plate roof to be cut by the holding unit 51, the shape of the contact surfaces 53, 55 that the fixed base 52 and the moving body 54 match may correspond to the shape of the folding plate roof. This is because the contact surfaces 53 and 55 can contact the folded plate roof without any gap by making it correspond to the shape of the folded plate roof, and the pressing of the folded plate roof by the pressing portion 51 is ensured.

FIG. 4 is an explanatory view showing the first embodiment of the cutting machine for building members, but the cutting machine 30A shown in FIG. 4 is a contact between the fixed base 52 and the moving body 54 for one folded plate roof. The surfaces 53 and 55 are formed in the shape of one mountain of an origami roof.
Similarly, FIG. 5 is an explanatory view showing a second embodiment of a building member cutting machine, but the cutting machine 30B shown in FIG. 5 has a fixed base 52 and a moving body 54 for three ore folding plates. The contact surfaces 53 and 55 are formed in the shape of three ridges of a folding roof.

On the other hand, when the cutting machine 30 presses the folding roof to be cut by the pressing portion 51, the shape of the contact surfaces 53, 55 that the fixed base 52 and the moving body 54 match corresponds to the shape of the folding roof. It is possible to use a free type that can accommodate any shape of the folded roof.
FIG. 6 is an explanatory view showing a third embodiment of the cutting machine for building members, but the cutting machine 30C shown in FIG. 6 has a fixed base 52 and a movable body for all folding roofs (free type). 54 contact surfaces 53 and 55 are formed in a plurality of continuous wave shapes. By forming in such a continuous wave shape, the unevenness of the contact surface engages with the folded plate roof, and the folded plate roof can be reliably pressed.

  The present invention can be widely used for cutting a building member to which asbestos adheres. The building member to which asbestos is attached is not limited to the folded roof described in the embodiment, and any building member to which asbestos is attached is included in this.
