Description

  The present invention relates to a light-weight curing device that is installed around a skeleton in demolition work or building work, and prevents an event that occurs along with the work and adversely affects the environment from reaching the outside of the construction site. .

  In demolition work and building work, events that adversely affect the environment occur along with the work, so a measure called “curing” is widely used to prevent such events from spreading outside the construction site. . In particular, there is an automatic lifting type curing scaffold recently implemented, which has a structure in which a soundproof panel is placed on a frame scaffold, which is installed on the outer periphery of the casing during dismantling work, and surrounds the casing.

  In the above-mentioned automatic lifting type curing scaffold, a considerable amount of work is required to attach the soundproof panel to the scaffold. Depending on the size of the building, for example, a standard building with more than a dozen floors above ground and several tens of meters will require about a month for assembly and dismantling, and the equipment weight will be about 100 tons. . In addition, the expenses required for the curing work were of course enormous, which was a heavy burden in dismantling and building work.

  For this reason, the inventor has conducted intensive research on the weight reduction of a member that functions as a soundproof panel. As a result of investigating the prior art, Japanese Patent Laid-Open No. 58-213957 has found an invention for a work curing facility, which is composed of a tent covering a structure and a plurality of balloons for lifting the tent. However, since the tent is easily affected by the wind, and the balloon that lifts the tent is strongly affected by the wind, applicable objects are limited.

  On the other hand, Japanese Patent Application Laid-Open No. 7-71120 discloses an invention in which a building construction sheet that covers a ceiling part is attached to a temporary scaffolding at the periphery of the ceiling part of the building, and a buoyancy member is disposed on the inside. According to this method, it is considered that the buoyancy member and the like are less affected by the wind. However, since the buoyancy member floats, there is a problem that the position of the temporary scaffold is not constant. In addition, parts other than the ceiling are not covered, and new measures need to be taken.

  This invention is made | formed in view of the said situation, The subject is to make it easy to cure according to the target building. Another object of the present invention is to secure the safety of curing by using a hollow body for curing, to achieve a significant weight reduction and to reduce the cost required for curing. is there.

  In order to solve the above-described problems, the present invention is a curing system that is installed around a frame in demolition work or building work, and prevents an event that occurs along with the work and has an adverse effect on the environment from spreading outside the construction site. As a device, a curing hollow body that is disposed around the housing and has an airtight bag-like structure for injecting gas into the interior and expanding, and any combination for coupling the curing hollow body and the housing The means of providing and configuring the means is taken.

  The present invention is a curing device for demolition work and building work of what is called a building, a structure, etc., and an event that occurs with the work and adversely affects the environment, that is, an object caused by the work, for example, Prevents harmful effects such as noise, welding spark scattering, and the fall of members, tool tools, and other objects from spreading outside the construction site. The present invention solves the above problems by applying a lightweight structuring technique to such a curing device.

  The apparatus of the present invention includes a curing hollow body that is disposed around a housing and has an airtight bag-like structure for injecting a gas into the inside and expanding the same. In addition, in this invention, a housing has the same general meaning in this industry, Therefore, it means the main structure of a building, or a framework.

  The material constituting the airtight bag-like structure is desired to be lightweight and strong enough to withstand external forces and disturbances applied during construction. For this purpose, for example, a woven fabric is formed using a chemical fiber having a function as a flame retardant, and a sheet material or a resin in which a film having a function as a soundproof material is bonded to the back surface is applied. Material such as sheet material with airtightness is suitable. In particular, when it is necessary to reduce the weight, for example, a material suitable for a balloon or an outer shell of an airship such as a nylon 66 film or a polyester film is effective.

  Since the curing hollow body is in the form of a panel disposed around the casing, the curing hollow body is panel-shaped in a state of being disposed around the casing. However, it is not necessary that the elements constituting the curing hollow body have to be panel-shaped. Therefore, it is naturally possible to construct a panel shape by combining a plurality of panel elements.

  Contrary to the above, the curing hollow body may be configured as one panel having an arbitrary size, and the inside thereof may be divided into a plurality of air chambers. This is because, if each air chamber is independent, even if one part is damaged, the other part is not affected by the damage, and the entire function is not impaired. The panel is easy to handle a simple bag-like structure, or a structure having a foldable skeleton and covered with an outer cover is also applicable.

  In this invention, although gas is inject | poured inside the hollow body for curing, air or gas other than air is used for the gas. As for air, it is possible to use air that is almost equal to the outside air temperature and heated air that is higher than the outside air temperature. In the latter case, buoyancy according to the temperature can be used, so the weight can be further reduced. It is.

  When the gas is air, the curing hollow body may be provided with an air inlet / outlet, but when the gas is heated air, the heated air is heated by a burner, and the curing hollow body is driven by a pump. It must be configured to be delivered to the body. Further, when the gas is helium gas, the curing hollow body is provided with helium gas injection and discharge ports.

  Furthermore, the device of the present invention comprises an arbitrary coupling means for coupling the bag-shaped air hollow body and the housing. The coupling means is not particularly changed except for the weight applied to the support portion in comparison with the coupling means for attaching the soundproof panel to the scaffold in the prior art, and any known fixing technique can be used.

  It is assumed that buoyancy is used for the device of the present invention. In the present invention, buoyancy consists of the concept of self-buoyancy and power buoyancy. Self-buoyancy is buoyancy that does not use power, and power buoyancy is buoyancy acquired by power. The device of the present invention comprises at least one of self-buoyancy or power buoyancy. Therefore, the buoyancy in the present invention includes not only the buoyancy itself in a general sense but also a force to move to float.

Therefore, first, self-buoyancy at 20 ° C. is examined. According to the scientific chronology, the density of air at 0 ° C. is 0.001293 g / cm ³ (1.293 kg / m ³ ).
The following formula, σ = · g / cm ³ (1)
Therefore, the air density at 20 ° C. is 0.00121 g / cm ³ (1.21 kg / m ³ ), and the air density at 80 ° C. is 1.00 g / cm ³ (1.00 kg / m ³ ) (H = 760 ( 1 atm) and 3 significant digits). The difference between them is 1.21-1.00 = 0.21 (kg / m ³ ). That is, since buoyancy of 0.21 kg per one standing rice can be obtained, a buoyancy of 2100 kg can be obtained with a hollow body for curing of 10,000 m ³ .

On the other hand, the density of helium gas is 0.1785 (kg / m ³ ) from the scientific chronology (however, the conversion formula for the temperature change of the helium gas density is unknown and is a numerical value of 0 ° C.). Then, 1.29−0.18 = 1.11 (kg / m ³ ). It must be taken into account that the temperatures are different, but helium gas provides a buoyancy of about five times that of heated air, so it can be seen that an equivalent buoyancy can be obtained with a volume less than one fifth.

  Further, as the power buoyancy, for example, a levitation mechanism capable of exhibiting buoyancy by incorporating a fan can be used. The levitation mechanism may be operated as necessary, such as when the apparatus of the present invention is installed or raised, and may not be operated at other times. Therefore, effective buoyancy can be given even in an apparatus that uses non-heated air as a gas.

  Further, the housing includes a lifting mechanism composed of a guide rail provided along the vertical direction of the casing and a moving body that can be moved up and down along the guide rail. The moving body and the hollow body for curing are coupled by a joint. Can be configured. At this time, the curing hollow body is connected to the winch by a wire rope, and is configured such that the vertical position can be adjusted by winding and loosening the winch.

  Since the present invention is configured and operates as described above, it is possible to easily perform the curing work corresponding to the target building by installing a curing device having a lightweight structure around the frame. There is an effect. Further, according to the present invention, by using a lightweight hollow body for curing, safety of curing can be ensured, a significant weight reduction can be achieved, and the cost required for curing can be reduced. it can.

  Hereinafter, the curing apparatus having a lightweight structure according to the present invention will be described in more detail with reference to the illustrated embodiment. 1 and 2 show a case where the light-weight curing apparatus 10 of Example 1 according to the present invention is applied to demolition work, and shows the side of a building, and surrounds the periphery of a main body 11 that is a main structure. As described above, a curing device 10 having a lightweight structure is installed.

  The curing device 10 of the present invention is composed of a curing hollow body 12 having an airtight bag-like structure in order to inject gas into the inside and expand it. The curing hollow body 12 is composed of a plurality of panel elements 13 having a pouch-like structure, and the panel elements 13 are configured in a panel shape as a whole. Although not shown, the panel element 13 may have a configuration in which the interior thereof is further divided into a plurality of small chambers.

  The housing 11 includes an elevating mechanism 15 including a guide rail 14 provided along the vertical direction of the housing 11 and a moving body 16 capable of elevating along the guide rail 14 (see FIG. 2). The raising / lowering mechanism 15 is for raising / lowering the curing hollow body 12, and the curing hollow body 12 and the moving body 16 are coupled by a joint. Further, the joint constitutes an arbitrary coupling means 17 for coupling the bag-shaped air hollow body 12 and the housing 11.

  In Example 1, since the elevating mechanism 15 is provided, the curing hollow body 12 can be lowered or raised as the dismantling work proceeds. For this purpose, the curing hollow body 12 is connected to the winch 19 by a wire rope 18, and is configured such that the vertical position can be adjusted by winding and loosening the winch 19.

  In addition, ascending / descending movement is not an indispensable requirement for the coupling means 17, and for example, it is naturally possible to select a fixed coupling means such as a wall connection. In addition to the elevating mechanism 15, it is also assumed that a coupling means for coupling the bag-like hollow body 12 and the casing 11 together like a wall connection is used.

  In the case of Example 1 of the present invention configured as described above, since the gas is air, a means for power buoyancy obtained by power for raising and lowering the curing hollow body 12 is provided. The power buoyancy is a levitation mechanism 24 that has a built-in fan and can exert buoyancy, and is attached to the outer surface of the curing hollow body 12 or the outer surface of the panel element 13 constituting it.

  The levitation mechanism 24 is equipped with a fan inside the duct, and the fan is driven by, for example, an electric motor. And as the electric power source, it is desirable to take a system that can be covered by a power line or a battery power source installed on the chassis 11 or the ground for further weight reduction. The curing hollow body 12 includes an inlet and an outlet for injecting air. The inlet and outlet may be the same connection port or independent connection ports.

  When the gas is air, it is possible to use heated air. Then, what uses heated air will be described as the curing device 20 of Example 2. This is additionally equipped with a burner 21 for heating the heated air and a pump 22 for feeding the heated air to the curing hollow body in the invention of Example 1. This can be configured (see FIG. 3). Reference numeral 23 denotes an air supply pipe. Since the other structure may be the same as that of Example 1, a code | symbol is used and detailed description is abbreviate | omitted.

The curing device 20 of Example 2 is an example in which the curing hollow body 12 has self-buoyancy along with power buoyancy acquired by power. According to the curing apparatus of Example 2, as described above, the self-buoyancy of 2100 kg can be obtained with the curing hollow body of 10000 m ³ with the temperature of the heated air being 80 ° C. In the case of using heated air in Example 2, it is difficult to lift the curing device only by self-buoyancy, but the effect of the curing device is significant because the load on the curing device can be significantly reduced.

  Furthermore, in this invention, the curing apparatus 30 of the structure of the hollow body for curing by self-buoyancy can be provided (refer FIG. 4). This embodiment obtained without using power will be described as Example 3 of the present invention. In FIG. 4, the basic configuration of Example 3 is depicted in the same manner as in Example 1. However, in Example 3, the curing hollow body 12 and the casing 11 are coupled to each other because a considerable proportion of the load is possible due to self-buoyancy. Only the arbitrary coupling means 17 constitutes a main part of the curing device 30.

Therefore, helium gas is used as the gas in Example 3, and the curing hollow body 12 has helium gas injection and discharge ports. Further, in Example 3, the levitation mechanism 24 is not required or is used as an auxiliary. As described above, helium gas has a buoyancy of about 5 times that of heated air, and can be simply calculated as 1000 m ³ to obtain a self-buoyancy of 2100 kg. The size is as small as (m), and there is no technical obstacle in practical use.

  For all of Examples 1, 2, and 3, the lifting mechanism 15 and the winch 19 are depicted in the reference drawing. However, the lifting mechanism 15 and the winch 19 are not essential as the curing devices 10, 20, and 30 of the lightweight structure of the present invention, and are elements that can be deleted and added as necessary. When the elevating mechanism 15 and the winch 19 are deleted, the curing hollow body 12 and the casing 11 can be coupled to each other as described above.

  In the above examples 1, 2, and 3, as the curing hollow body 12, so as to be able to withstand the external force and disturbance exerted during the construction, for example, a woven fabric is formed using a chemical fiber having a function as a flame retardant, On the back side, a material such as a sheet material laminated with a film having a function as a soundproofing material is used. In addition, materials suitable for balloons and airship skins, such as nylon 66 film and polyester film, are effective in terms of light weight, and are selected in consideration of external forces and performance against disturbances.

  Since the present invention is configured in this way, it can be installed around the housing in dismantling work or construction work, and the curing hollow body 12 and the housing 11 can be joined by any coupling means. There is no need to install a scaffold, and the construction period can be shortened to a few days. Moreover, about the weight of the curing apparatus 10,20,30, weight reduction is anticipated to about 1/10 about 10t on the same conditions as what was described in background art. Therefore, the construction cost can be greatly reduced, and the safety is improved because the vehicle does not fall.
