Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that an immense amount of working time and cost are required for preparatory work because there is no effective method for securing a worker's safety and peripheral residents' safety on a job site of asbestos countermeasures except, in order to ensure the safety, a method in which scattering of asbestos dust to the periphery is prevented by means of a curing sheet fitted with a negative-pressure duct collector for separating the working space and a method in which the worker defends his/her own security by wearing protective clothing and a protective mask and passes through a security room for entering/leaving the separated space. <P>SOLUTION: For the work generating poisonous dust, as typified by the asbestos, and poisonous medicine spraying construction work, a glove box with an open end is pressure-bonded to a countermeasure-applied surface, so that a cured space can be obtained without the exposure of the harmful substance to the worker and the peripheral residents. Specifically, a frame structure, which supports a glove-box body and enhances adhesion to the countermeasure-applied surface by attaching a cushioning material, is disposed on the open end. Also, a jack, a turnbuckle, a spring or a leverage mechanism for pressure-bonding the glove box to the countermeasure-applied surface at equal pressure is provided. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a glove box, for example, and more particularly to a glove box used in an asbestos wetting process before asbestos containment work or asbestos removal work.

  It is requested at various construction sites that asbestos measures should be taken using as simple equipment and curing methods as possible. As one method to meet this demand, for example, as disclosed in Patent Document 1 and Patent Document 2, when the wall or ceiling is covered with a finishing material, the finishing material is perforated, the nozzle portion is inserted, and the medicine is sprayed. A method has been proposed. Further, in Patent Document 3, a wall made of a curing sheet is newly formed at an appropriate distance from the asbestos surface, and a drug is sprayed by opening a hole in the curing sheet, rather than perforating the finishing material constituting the wall or ceiling. A method has been proposed. Furthermore, in Patent Document 4, instead of constructing a wall or ceiling finishing material or a new curing sheet wall surface, a double duct-shaped cover structure is used to spray the drug inside the inner cover and suction the outer cover part, It is proposed to suck asbestos dust.

  However, in the methods of Patent Document 1 and Patent Document 2, a large amount of dust is already scattered in the work place at the stage of drilling in the finishing material, which goes against the purpose of preventing asbestos scattering. Dust containing asbestos that has been deposited on the back of the ceiling after a long period of time scatters around in an instant. In such a situation, to ensure the safety of workers and the safety of the residents in the surrounding area, as well as the usual asbestos removal, containment or enclosure in the work room, complete curing is performed, and It is indispensable to install a security room for wearing a protective mask and entering and exiting the curing. In addition, since the method of Patent Document 3 does not pierce the finishing material of the wall or ceiling, it does not roll up dust containing long-standing asbestos, but asbestos is exposed to construct the wall of the curing sheet. Carpenter work is required in the space to be used, and measures to prevent asbestos dust scattering are required. Furthermore, in the method of Patent Document 4, the asbestos surface is always rubbed by pressing the equipment, and it is difficult to prevent asbestos dust from being scattered to the surroundings unless the inner cover is large enough to cover the entire asbestos adhesion surface.

  As described above, the conventional asbestos removal, containment, or enclosure technique, and the methods disclosed in Patent Documents 1, 2, 3, and 4, are indispensable for curing workers and surrounding residents. It was.

  In other words, the conventional technology requires a curing that is a strict sealed space using a thick sheet, and within that curing, workers do not wear strict protective clothing or install a security room to ensure their own safety. Countermeasures were difficult.

  The present invention is intended to solve such problems in the prior art, and includes a glove box equipped with a drilling tool necessary for drug spraying, a nozzle part for drug spraying, a dryer blower port, an exhaust device exhaust port, and the like. It aims at providing a safe working environment by crimping | bonding to a wall surface or a ceiling surface.

  In order to solve this problem, the glove box according to claim 1 of the present application is characterized by having an open end for processing the ceiling surface or the wall surface. Thereby, the operator can take measures without scattering of harmful dust to the surroundings at the same time by the isolation space formed by the glove box without contacting any harmful dust such as asbestos or medicine.

  In this case, as in the second aspect of the present invention, the opening end portion of the glove box may have a structure having a cushioning material for the purpose of ensuring adhesion to the target surface and equal pressure bonding. Thereby, the harmful | toxic dust scattering during a series of work can be prevented, and the opening edge part curing for preventing the scattering of dust scattering can be made unnecessary.

  Further, as in the present invention as shown in claim 3. It is good also as a structure which has a jack, a turnbuckle, a spring, or a lever in order to fix the whole glove box equipped with the said cushion material reliably throughout the whole work. Thereby, safe work can be performed by fixing at the beginning of glove box installation.

  Further, as in the present invention described in claim 4, the glove box itself is made of a hard transparent material such as an acrylic resin, a polycarbonate resin, or glass that can be found in a normal glove box, and it is flexible while ensuring transparency. For example, highly flexible vinyl chloride resin, polyethylene resin, or the like, or a sheet containing fibers for the purpose of increasing the strength thereof may be used. Thereby, the weight of the whole glove box becomes small, handling becomes easy, and it becomes possible to make the whole operation | work highly efficient.

  Further, as in the present invention described in claim 5, the ceiling board is usually mounted by mounting the left and right gloves on two adjacent surfaces or two opposing surfaces instead of a glove box in which the left and right gloves are mounted in one plane. It is good also as a structure which improves workability | operativity of work, such as drilling. Thereby, it becomes possible to extend the movable range of the hand in the operation | work which uses a glove.

  The cushion material according to claim 2 can be made of various materials as long as it is a material that promises a thickness and adhesion sufficient to absorb the unevenness of the surface to be crimped, an aluminum frame, and the like. In some cases, it is desirable to use a material having a smooth surface so as not to hold harmful dust and the like in addition to the adhesion.

  The cushion material can be attached to the glove box with a structure that spans the opening end face of the glove box, that is, the cut surface of the glove box component material. It is easy to obtain stability at the time of crimping by providing a frame structure and attaching a cushion material to the entire width of the frame.

  The “jack, turnbuckle, spring, or insulator structure” of claim 3 particularly uses a jack or a turnbuckle when the ceiling surface is targeted, and determines the contact state between the glove box opening end surface or the cushion material and the crimping surface. Gradually lift up the glove box while checking, and stop the push-up by the jack or turnbuckle when the opening end face is in full contact, and fix it.

  Of the “jack, turnbuckle, spring or lever structure” of claim 3, the spring or lever structure is used particularly on a vertical target surface such as a wall, and a base supporting the glove box is installed and fixed in the vicinity of the work surface. After that, a stable crimping is performed by pressing the glove box against the wall surface by a lever structure balanced by a spring or a weight of an appropriate weight from the pedestal or the pedestal column.

  The term “consisting of a flexible and durable material such as a thick vinyl sheet or a fiber-embedded sheet, or a flexible or durable material” in claim 4 refers to a glove box that is usually composed of a hard transparent material. Consists of vinyl sheet and fiber-incorporated material, which can securely isolate the site where harmful dust is generated and increase the degree of freedom of work inside the glove box. To. Select a tough material to prevent the seat from being damaged by tools, etc., prepared in advance in the glove box, but for safety, put a bag to store the tool in the glove box. In addition, it is possible to prevent the load on the lower part of the glove box by fixing the bag to the frame of the opening end.

  By using the glove box of the present invention having such a configuration, it is possible to perform on-site construction with high possibility of contact with harmful dust as typified by asbestos or coating construction in the case where the chemical used is highly harmful. It becomes possible to carry out safely by simple preparatory work.

It is a lineblock diagram showing the whole glove box concerning one embodiment of the present invention. It is a lineblock diagram showing what attached the turnbuckle mechanism to the lower part in the glove box concerning one embodiment of the present invention.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and the range necessary for the description of the relevant part of the present invention will be mainly described. Are according to known techniques.

  As shown in FIG. 1, the present invention has a basic structure in which a rectangular parallelepiped is formed of a transparent hard material and only one surface thereof is opened. In FIG. 1, a structure in which a flange structure is provided to increase the strength of the opening end of the glove box and to improve the adhesion, and a cushion material is further attached is shown.

  Often in asbestos containment work, etc., the maintenance opening of the ceiling board will be used, but in that case, the opening end of the glove box is placed so as to cover the entire maintenance opening. However, if the maintenance port can be covered, there is no particular numerical limitation on the size of the opening end.

  In addition, if there is no maintenance port at an appropriate position on the ceiling board, the board will be cut again to open the work port, but the glove is constructed close to the opening end of the glove box to facilitate the work. To do.

  Although FIG. 1 shows a configuration having a flange portion, if the surface to be crimped is smooth and can be bonded with a curing tape or a masking tape, a glove box that does not necessarily have a flange portion does not necessarily have a gap. By sealing the part with a curing tape etc., it is possible to isolate harmful dust and harmful drugs.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  Further, the above-described examples are merely examples of embodiments for embodying the technical idea according to the present invention, and the technical ideas according to the present invention can be applied to other embodiments. Is possible.

  By using the glove box with an open end of the present invention, by a simple installation such as a containment that may be exposed to harmful dust such as asbestos or an antibacterial agent spraying work in which the medicine itself is harmful, By creating a space that is completely isolated from the workers or the surrounding residents, it offers a wide range of possibilities for spraying various drugs.

  The glove box with an open end of the present invention provides a possibility for spray construction such as starch paste that hardens in contact with dust and dust for the purpose of countermeasures against dust and dust accumulated on the back of the ceiling in a house with allergic family members. is there. It is thought that measures can be taken by fixing the causative agent of allergies together with dust, but if dust is generated by dust removal work, it will fall to the end.

  As described above, the present invention provides a countermeasure method suitable for containment of asbestos hidden behind the ceiling or on the wall surface. However, even in the asbestos removal work, the highly permeable wetting agent is removed before the removal work. By spraying as much as possible, we offer the possibility of completing work with little dust generation by moving to the work of removing the board and the like after completion of wetting.
