Description

  The present invention relates to a compartment structure and a compartment method for a highly airtight space, and more specifically, for the physical containment of biohazardous substances and the maintenance of high cleanliness of indoor spaces. The present invention relates to a highly airtight space partition structure and a partitioning method for partitioning or constructing a highly airtight room requiring high airtight performance in a building by a wall structure and a ceiling structure of a dry construction method.

  Biohazard facilities that conduct research on biologically dangerous pathogens are known. Since biohazard facilities cultivate pathogens with biological hazards, it is necessary to reliably prevent biological hazardous materials (biohazard materials) from diffusing outside the facility. For this reason, not only strict standards or regulations are established in the pathogen handling method and facility management and operation (JP-A-2014-171587, etc.), but the physical structure depends on the structure of the facility and the structure of the facility. Various measures such as containment are taken (JP 2009-58191 A).

In general, laboratories that open and operate biohazardous substances are classified into biosafety levels 1 to 4 (BSL1 to BSL4) according to the biological dangers of the handled substances. BSL4 is a biohazard facility that can handle extremely dangerous pathogens such as Ebola hemorrhagic fever and Lassa fever. BSL3 is a biohazard that handles high-risk pathogens such as avian influenza and rabies. BSL2 and BSL1 are biohazard facilities that handle pathogens with relatively low risk. Physical containment techniques in advanced biohazard facilities such as BSL3 or BSL4 can be classified primarily as follows.
(1) Architectural structural barriers that depend on architectural structures and floor plans
(2) Barrier based on differential pressure control between rooms designed for unidirectional airflow
(3) Exhaust filtration treatment by exhaust purification equipment such as HEPA filter
(4) Waste liquid sterilization treatment depending on waste liquid treatment equipment with waste liquid sterilization function
(5) Sterilization of laboratory instruments using sterilization equipment such as double-sided autoclave

  The above-mentioned differential pressure control between chambers sets the indoor air pressure of the chamber (hereinafter referred to as “biohazard chamber”) where the biohazardous material is opened / operated to an extremely negative pressure (negative pressure). It is a technology that tries to prevent it from spreading outside. The value of the inter-room differential pressure differs depending on the standards and voluntary standards of each country, but the indoor environment of the BSL4 biohazard chamber is currently set to a high pressure value of 100 to 250 Pa (for example, 150 Pa). In many cases, the inter-room differential pressure during the airtight performance test is set to an extremely high pressure value of, for example, 500 Pa (Canadian Biosafety Standards).

  On the other hand, when the wall body and ceiling that divide the indoor space do not have an airtight performance that can withstand such an inter-room differential pressure, it is difficult to maintain the differential pressure inside and outside the room. That is, the inter-room differential pressure control is premised on the construction of an architectural structural barrier that reliably prevents air inflow and outflow (ventilation or leakage) in the indoor space and outdoor space. It is a technical element that contributes to the safety of biohazard rooms.

  In general, reinforced concrete walls and floors that are constructed by wet construction have a seamless structure with no joints, so they are more durable and more solid than dry construction structures such as light iron partition walls. It is considered highly advantageous in terms of air permeability, air permeability and water permeability. For this reason, the architectural structural barrier of a biohazard room is usually partitioned by a reinforced concrete structure (wall, column, beam, floor slab, roof slab, etc.). The wet method is generally a method using a hydraulic material such as concrete, cement mortar, or stucco as a main material or a main component. On the other hand, the dry method generally does not use such a hydraulic material as a main material or a main component, but uses an interior / exterior surface material, a composite panel, a metal mold material, etc. by a locking tool, a mooring tool, an adhesive, etc. It is a method of construction or assembly.

  In addition, examples of the highly airtight space other than the biohazard room include clean rooms such as industrial clean rooms and bio clean rooms having a cleanness of class 10000 or less or 1000 or less. In general, in this class of clean room, the air pressure in the indoor space is set to a relatively high positive pressure (positive pressure) in order to prevent dust, microorganisms and the like from entering the indoor space. The structure of this type of clean room is described in, for example, JP-A-2015-190262. The room pressure in the clean room is usually not set to a value as high as the room pressure in the biohazard room. Therefore, in many clean rooms, the interior space of the interior space such as calcium silicate board and gypsum board is lightweight. It is divided by the wall and ceiling of the dry construction method fixed to the steel base. Also known is a panel assembly type (dry construction method) clean room structure in which an indoor space is formed by a heat insulating panel or a composite panel formed by coating a resin foam with a color steel plate or the like (JP-A-8-68221, etc.) ).

  In a highly airtight room such as a clean room partitioned by a wall and ceiling of a dry construction method, in order to maintain negative pressure or positive pressure in the interior space, the joint part of the wall of the building interior, the connecting part of the wall and ceiling, the wall and The connecting portion of the floor is hermetically sealed with a sealing material (agent), thereby preventing the inflow and outflow (ventilation or leakage) of air in the indoor space and the outdoor space. As the sealing material (sealing material), an elastic or viscoelastic sealing material such as a silicon sealing material, an acrylic sealing material, or a urethane sealing material is generally used. Japanese Patent Application Laid-Open No. 11-1976 describes a seal structure having a structure in which different kinds of sealing materials are filled in the joints in a double layer or two layers in order to improve the airtight performance of the seal joints filled with the sealing materials. . This seal structure is intended to make the at least one sealant function effectively with respect to different factors that damage the seal portion by utilizing the difference in characteristics of the different sealant.

JP 2014-171587 JP 2009-58191 A JP-A-2015-190262 JP-A-8-68221 JP-A-11-1976

  In general, a dry construction structure is advantageous over a wet construction structure in terms of reducing the weight of the building, improving workability, shortening the construction period, and reducing the construction cost. In addition, although reinforced concrete walls and floors are advantageous in terms of non-breathability and non-breathability, there is a tendency for dry shrinkage cracks due to dry shrinkage after construction to occur in concrete structures. In addition, there is a possibility that wear, damage, etc. due to deterioration factors such as neutralization and rebar corrosion may occur. For this reason, the non-breathability or non-breathability of the concrete structure is not necessarily permanent, and its aging deterioration must be considered. Moreover, in Japan, there is a unique situation that a relatively large-scale earthquake is highly likely to occur, so structural cracks and the like occur in reinforced concrete walls due to the behavior of buildings and interlayer displacement during a large-scale earthquake. There are concerns that arise.

  For this reason, even in highly airtight rooms with extremely high room differential pressure, such as biohazard rooms, we are considering or constructing a highly airtight space with dry construction walls and ceilings such as light iron partition walls. It is meaningful to do.

  When constructing the walls and ceilings of high airtight rooms by the dry construction method, there are various types of joints such as joints between wall materials, joints between ceiling materials, joints between wall materials and ceilings, joints between wall materials and flooring materials, etc. Seams or joints must be airtight. However, when these seams or joints are hermetically sealed with a sealing material, the sealing material is likely to break or crack when the joints or joints are deformed following the building behavior and interlayer displacement. For this reason, it is possible to prevent breakage, cracks, etc. from occurring in the sealing material filling joints such as seams of wall materials and ceiling materials, and to maintain an airtight structure that maintains a high inter-room differential pressure over a long period of time. It is extremely difficult.

  In this regard, it may be possible to consider measures for improving the durability of the joint itself by adopting the above-described seal structure (Patent Document 5) in which the joint material is filled in a double layer or two layers in the joint portion. However, no matter how much the seal structure itself can be optimized, simply changing the conventional single-layer-filled sealant to a multi-layer fill, the wide variety of sealant-filled joints in the airtight chamber is relatively large. It is difficult to fully adapt to the relatively large building behavior and interlaminar displacement that occurs when an earthquake occurs.

  The present invention has been made in view of such circumstances, and the object of the present invention is to ensure that fractures, cracks, etc. occur in the sealing material filling joints such as seams of wall materials and ceiling materials. An object of the present invention is to provide a partition structure for a highly airtight space and a partitioning method thereof, which can prevent and partition a high airtight chamber in a building by a wall structure and a ceiling structure of a dry construction method.

In order to achieve the above object, the present invention provides a highly airtight space partitioning structure in which a highly airtight room having high airtightness performance is partitioned or constructed in a building by a wall structure and a ceiling structure of a dry construction method.
The wall structure has a plurality of metal studs erected along the wall core, and wall materials attached to the indoor side of the studs,
The ceiling structure has a roof structure, an upper floor structure, or a ceiling foundation suspended by a support structure portion on the ceiling, and a ceiling surface material fixed to the ceiling foundation,
The wall surface material and the ceiling surface material are separated from each other in the ceiling outer peripheral region so as to form a horizontal surface material separation band in the ceiling outer peripheral region that enables relative displacement of the wall structure and the ceiling structure. ,
A surrounding edge member is disposed in the face material separation zone, and the surrounding edge member is fixed to the wall structure, and the ceiling member is formed so as to form a horizontal joint space between the lower surface of the ceiling face material. A partition of a highly airtight space, wherein the joint space is separated from and separated from the face material, and the joint space is filled with a sealing material that is deformed so as to absorb relative displacement of the wall structure and the ceiling structure. Provide structure.

From another point of view, the present invention relates to a method for partitioning a highly airtight space in which a highly airtight room having high airtightness performance is partitioned or constructed in a building by a wall structure and a ceiling structure of a dry construction method.
A plurality of metal studs are installed along the wall core, and wall materials are attached to the interior side of the studs, and the ceiling foundation is suspended by a roof structure, a floor structure on the upper floor, or a support structure part on the ceiling. Hanging, fixing the ceiling surface material to the ceiling base, and constructing the ceiling structure,
A horizontal surface that allows relative displacement of the wall structure and the ceiling structure by separating the wall material and the ceiling surface material from each other in the outer periphery of the ceiling during the construction of the wall structure and the ceiling structure. Form a material separation zone in the outer periphery of the ceiling,
A surrounding edge member is arranged in the face material separation band, and the surrounding edge member is fixed to the wall structure, and is separated from the ceiling face material to form a horizontal joint space between the lower surface of the ceiling face material. And providing the joint space with a sealing material which is deformed so as to absorb relative displacement between the wall structure and the ceiling structure.

  According to the above configuration of the present invention, the ceiling structure and the wall structure are separated in the face material separation band and separated so as to be relatively displaceable. Therefore, the ceiling structure and the wall structure are constrained to each other in the face material separation band. The relative displacement can be relatively large. A relatively large relative displacement (horizontal displacement) in response to the behavior of the building and the interlaminar displacement occurs in the face material separation zone, but the sealing material in the horizontal joint space absorbs this relative displacement due to its deformation. . For this reason, the load of the seismic force or the excitation force is concentrated on the horizontal joint portion without greatly acting on the entire wall surface and the entire ceiling surface.

  In other words, the effects of the building behavior and the interlaminar displacement at the time of the earthquake appear relatively large in the horizontal joint part, so the load or stress during the earthquake acting on the joints on the wall surface and joints on the ceiling surface is reduced. Fractures, cracks, and the like are unlikely to occur in the sealing material for joints other than the horizontal joints. Thus, according to the present invention, the seal structure between the surrounding edge member and the ceiling surface material can be optimized for the behavior of the building or the followability to the interlayer displacement. And can be partitioned or constructed in the building relatively easily by the ceiling structure.

In order to achieve the above object, the present invention provides a highly airtight space partitioning structure in which a highly airtight chamber having high airtightness performance is partitioned or constructed in a building by a wall structure and a ceiling structure of a dry construction method.
The wall structure has a plurality of metal studs erected along the wall core, and wall materials attached to the indoor side of the studs,
The first and second face material separation bands that allow relative displacement of each wall structure are formed at the connection portion or the intersection portion of the first and second wall structures having different wall core directions. The wall surface materials of the second wall structure are separated from each other at the connection portion or the intersection portion,
A wall corner member is disposed in the face material separation band, and the wall corner member is fixed to the first wall structure and is separated from and separated from the second wall structure. A vertical joint space is formed between the wall surfaces, and the joint space is filled with a sealing material that is deformed so as to absorb the relative displacement of the first and second wall structures. Provide a spatial structure.

From another point of view, the present invention relates to a method for partitioning a highly airtight space in which a highly airtight room having high airtightness performance is partitioned or constructed in a building by a wall structure and a ceiling structure of a dry construction method.
A plurality of metal studs are built along the wall core, and wall materials are attached to the indoor side of the studs.
In order to form a vertical surface material separation band that enables relative displacement of each wall structure at the connecting portion or the intersecting portion of the first and second wall structures having different wall core directions. The wall materials of the wall structure are separated from each other at the connection part or the intersection part,
A wall corner member is disposed in the face material separation band, the wall corner member is fixed to the first wall structure, and the wall corner member is separated from the second wall structure so as to be a wall surface of the second wall structure. A vertical joint space is formed between
Provided is a method for partitioning a highly airtight space, wherein the joint space is filled with a sealing material that is deformed so as to absorb relative displacement between the first and second wall structures.

  According to the above configuration of the present invention, the wall structures having different wall core directions are separated in the face material separation band and are separated so as to be relatively displaceable. Therefore, the wall structures are restrained from each other in the face material separation band. The relative displacement can be relatively large without any problem. A relatively large relative displacement (horizontal displacement) in response to the behavior of the building and the interlaminar displacement occurs in the face material separation zone, but the sealing material in the vertical joint space absorbs this relative displacement due to its deformation. . For this reason, the load of seismic force or excitation force concentrates on this vertical joint part, without acting large on the whole wall surface and the whole ceiling surface.

  That is, the effects of the building behavior and the interlayer displacement at the time of the earthquake appear relatively large in the vertical joint part, so the load or stress during the earthquake acting on the joints on the wall surface and joints on the ceiling surface is reduced. Fractures, cracks and the like are unlikely to occur in the sealing material for joints other than the vertical joints. Thus, according to the present invention, as for the seal structure between the wall corner member and the wall surface material, it is only necessary to optimize the followability with respect to the behavior of the building or the interlayer displacement. It can be partitioned or constructed in the building relatively easily by the ceiling structure.

  Preferably, the wall structure includes an upright portion of a concrete structure extending integrally upward from the concrete of the floor structure and having a wall thickness corresponding to the wall thickness of the wall structure. The rising portion has an upper surface on which a floor runner extending in the direction of the wall core and supporting the studs can be laid. The height of the rising portion is preferably set to 200 mm or more, more preferably 250 mm or more.

  This start-up part not only constitutes the base of the floor where the flooring material is raised from the baseboard part, but also spilled chemicals, chemicals, indoor sterilizing liquid, disinfecting liquid, decontamination liquid And the like function as a dam or a bank that prevents leakage of the air from the outside through the lower end of the wall.

  More preferably, the first or second sealing material layer exposed to the indoor space, and a double or two-layer structure comprising a second sealing material layer located behind or behind the first sealing material and concealed from the indoor space. The sealing material having a joint width and thickness of 10 mm or more is filled in two or two layers in the joint space so as to form a hermetic seal structure. A silicon-based sealing material can be suitably used as the sealing material.

  Such a double or two-layer hermetic seal structure not only improves hermeticity, but also allows maintenance and management of the seal structure by replacing only the indoor sealing material that is relatively susceptible to deterioration. This is extremely advantageous in practice. For example, the indoor space of a biohazard chamber is sterilized, disinfected or decontaminated with formalin, hydrogen peroxide, etc. at a relatively high frequency, and the indoor sealing material deteriorates at a relatively early stage, with a relatively high frequency. There is a tendency to be exchanged at. However, the double or two-layer hermetic seal structure is extremely advantageous in practice because only the indoor sealing material needs to be replaced.

  Preferably, the sealant has a design allowable expansion / contraction rate and a design allowable shear deformation rate of 25% or more and 50% or more with respect to behavior or displacement during an earthquake (more preferably, 30% or more and 60% or more, respectively). Sealing material) can be used. Focusing on the applicability to earthquake behavior or displacement, the joint joint width of the hermetic seal structure is the building's inter-layer displacement angle, joint joint height position, and design material's allowable expansion / contraction rate or design. It is substantially determined in relation to the allowable shear deformation rate. For this reason, in a building where the interlayer displacement angle of the building is set to be relatively large, the joint width is also set to a relatively large value. For example, the joint width of the seal structure is set within a range of 20 mm to 50 mm. . On the other hand, when emphasizing the workability of the sealing material, it is desirable to suppress an increase in joint width, and the joint width is preferably set to 30 mm or less, more preferably 25 mm or less.

  According to the partitioning structure and partitioning method for a highly airtight space according to the present invention, it is possible to prevent breakage, cracks, etc. from occurring in the sealing material filling joints such as the joints of the wall material and the ceiling material, and to dry the high airtight chamber. It can be partitioned or constructed in a building relatively easily by the wall structure and ceiling structure.

The biohazard facility B includes a biohazard chamber C, a buffer area D, and an overhead space (interstitial space) E. In the present embodiment, the biohazard facility B only constitutes a part of the building A, but the entire building A can also be configured as the biohazard facility B.

  The biohazard chamber C is partitioned by a wall structure 1 of a dry construction method and a ceiling structure 2 of a dry construction method. In the present embodiment, the wall structure 1 is a partition wall of a dry construction method in which a building interior surface material is fixed to a steel stud 11 (FIG. 2) made of a square steel pipe, and is erected on a floor structure F. , Extending vertically to the roof structure R.

  The buffer area D is formed between the inner wall Wi and the indoor wall structure 1, and is formed between the outer wall Wo and the outdoor wall structure 1. The buffer area D is an area within the management area of the biohazard facility B, but a general environment building space where facility managers permitted to enter the biohazard facility B can walk for inspection and maintenance management, etc. It is.

  The building A includes a frame J of a steel vine shelf structure suspended from a beam G at a roof level. The skeleton J is a “support structure” defined in the specific ceiling standard. The framework J has a structure in which a horizontal lattice beam member N is suspended in a ceiling space by a large number of vertical columns M. The upper end portion of the vertical column M is fixed to the beam G by a steel bracket, anchor bolts or the like (not shown). The beam member N is fixed to the lower end portion of the vertical column M by a steel bracket, a bolt / nut assembly or the like (not shown). A steel floor material Q such as a steel grating that constitutes a catwalk (high-altitude walkway) for inspection and maintenance management is laid on the beam member N.

  The ceiling structure 2 is suspended below the frame J by suspension bolts K. The length of the suspension bolt K is preferably set within a range of 300 to 1000 mm (in this embodiment, about 600 mm). The ceiling equipment space E in the upper area of the beam member N constitutes a construction equipment space where various kinds of construction equipment (equipment equipment, ducts, piping, etc.) are installed or arranged, and the above-mentioned facility managers inspect.・ It is a general environment building space where people can walk or work for maintenance. It is desirable to secure as large a height as possible for the equipment space E in the ceiling, but in general, considering the structure of the entire building, height restrictions, etc., about 1800 to 2500 mm It is often designed as a building facility space having a height of

  As shown in FIG. 1, the ceiling structure 2 extends horizontally in the ceiling area of the biohazard chamber C to form the ceiling surface of the biohazard chamber C, and terminates at a position close to the wall structure 1. As shown in FIG. 2, the wall structure 1 extends in the XY direction, and the wall structures 1X and 1Y extending in the X direction and the Y direction are connected to each other at a wall corner (corner portion) V in the architectural plan. FIG. 2 shows the door 9 between the biohazard chambers C and the steel studs 11 arranged on the wall core of the wall structure 1 at a predetermined interval.

  3 is a longitudinal sectional view showing the structures of the wall structure 1 and the ceiling structure 2, and FIG. 4 is an enlarged sectional view of various joint portions shown in FIG.

  As shown in FIG. 3, the ceiling structure 2 includes a suspension bolt K suspended from the frame J (FIG. 1), a T-bar-shaped field edge 21 attached to the lower end of the suspension bolt K, and a mooring tool 22. And a composite panel 20 attached to the edge 21. The composite panel 20 is a heat insulating panel having a thickness of about 50 mm formed by coating the resin foam 20b with a covering material 20a such as a color steel plate. Adjacent composite panels 20 are connected to each other through a sealing material filling joint 23 extending as a grid joint on the entire ceiling surface. The joint width t1 of the joint 23 is set to 10 to 20 mm, for example, 12 mm.

As shown in FIG. 4A, the metal joint bottom member 24 is positioned in the joint, and the backup material 25 and the sealing material 26 are laid or filled in the joint in double or two layers. The construction method of the sealing material filling joint 23 having a double or double layer structure is as follows.
(1) Insert a backup material 25a having a thickness of about 3 mm into the joint.
(2) The sealing material 26a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) A backup material 25b having a thickness of about 3 mm is inserted into the joint.
(4) The sealing material 26b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
As the sealing material 26, a silicon-based sealing material can be preferably used.

  As shown in FIG. 3, the wall structure 1 includes a steel stud 11, a lower runner (or floor runner) 12, an upper runner or a ceiling runner (not shown), building interior surface materials 13, 14 and 15, and concrete startup. Part 3. The upper runner is fixed to the lower surface of the roof slab R (FIG. 1), for example. The steel stud 11 is a square steel material having a cross-sectional dimension of 100 mm × 100 mm (plate thickness 2.3 mm). The steel stud 11 is erected at a wall core position at a predetermined interval as shown in FIG. 2 by locking or mooring the lower end portion and the upper end portion to the lower runner 12 and the upper runner. The interval between the steel studs 11 is set to an interval of 300 to 600 mm in the wall core direction, for example, an interval of 450 mm. In the present embodiment, the upper and lower runners are light iron (LGS) wall base runners (JIS A 6517-2010: steel base material for construction). If desired, the distance between the steel studs 11 is set to about 800 to 900 mm, and a relatively lightweight or low-rigidity steel stud (such as C-shaped steel (100 mm × 45 mm (plate thickness 0.8 mm))) (not shown). May be disposed between the steel studs 11.

  As shown in FIG. 3, the lower runner 12 is fixed to the upper surface of the concrete rising portion 3. The rising portion 3 is a reinforced concrete raised portion integrally extending vertically upward from the floor structure F with a thickness approximately equal to the wall thickness of the wall structure 1, and the height of the rising portion 3 is the floor surface. To about 200 to 300 mm. The coating material 30 applied on the floor structure F is applied to the rising surface of the rising portion 3 on the side of the biohazard chamber C (hereinafter simply referred to as “indoor side”), and the coating material is curved. 31 and a coating floor rising part 32 are formed. A parting edge 40 is disposed at the boundary between the face material 13 and the coating floor rising portion 32. The riser unit 3 integrated with the floor structure F leaks chemicals or chemicals spilled on the floor surface on the indoor side, indoor sterilizing liquids, disinfecting liquids, decontaminating liquids and the like through the lower end of the wall. It functions as a ridge, dam or dam that reliably prevents this.

  As shown in FIG. 4 (C), the parting edge 40 is a long metal member (in the present embodiment, an aluminum shape member) having a Z-shaped or key-shaped cross section attached to the indoor upper end of the rising portion 3. The upper end portion of the coating material rising portion 32 ends close to the parting edge 40.

A back-up material 35 and a sealing material 36 are laid or filled in two or two layers in a groove having an opening on the lower surface formed by the upper end portion of the coating material rising portion 32 and the key-shaped protrusion of the parting edge 40. A double or double layer sealing material filling joint 33 is formed. The construction method of the joint 33 is as follows.
(1) Insert a backup material 35a having a thickness of about 3 mm into the groove.
(2) The sealing material 36a is injected or filled into the joint to a thickness of about 5 to 10 mm (for example, 7 mm).
(3) A backup material 35b having a thickness of about 3 mm is inserted into the groove.
(4) The sealing material 36b is injected or filled into the groove to a thickness of about 5 to 10 mm (for example, 7 mm).
As the sealing material 36, a silicon-based sealing material can be preferably used.

  In general, it is extremely difficult to perform the artificial work of injecting or filling the sealing material into the lower surface opening of the parting edge arranged in the baseboard part because the working space and the working posture are extremely limited or restricted. In the embodiment, since the parting edge 40 is disposed at a height of about 200 to 300 mm from the floor surface by the formation of the rising portion 3, the sealing material 36 is filled in the groove of the parting edge 40 from the lower side or The workability of the artificial work to be injected is considerably improved.

  As shown in FIG. 3, a relatively thick face material 13 having a thickness of about 25 to 45 mm (in this embodiment, a thickness of 35 mm) is fixed to the indoor side surface of the steel stud 11 as an interior wall material. As shown in FIGS. 4B and 4C, the face material 13 includes a core material 13b made of a plate-like resin foam and a thin metal plate 13a covering the inner side surface and the outer peripheral end surface of the core material. It is a composite panel having a specific gravity of 0.5 or less (preferably, a specific gravity of 0.4 or less). As shown in FIG. 4C, the lower end surface of the face material 13 is separated from the parting edge 40, and the joint width t2 = 10 to 15 mm between the face part 13 and the parting edge 40, for example, A sealing material filling joint 43 having a joint width t2 = 12 mm is formed.

The joint 43 has a joint structure in which the backup material 45 and the sealing material 46 are laid or filled in double or two layers in the joint. The concrete construction method of the joint 43 is as follows.
(1) Insert a backup material 45a having a thickness of about 5 mm into the joint.
(2) The sealing material 46a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) A backup material 45b having a thickness of about 5 mm is inserted into the joint.
(4) The sealing material 46b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
Note that a silicon-based sealing material can be preferably used as the sealing material 46.

  As shown in FIG. 3, a face material 14 is fixed to the outdoor side surface (the buffer area D side) of the steel stud 11 as a bottom surface material. The face material 14 is, for example, a gypsum board having a thickness of 12.5 mm. A face material 15 is fixed to the outer surface of the face material 14 as an upper surface material. The face material 15 is, for example, a calcium silicate plate having a thickness of 6.0 mm. The face materials 14 and 15 are constructed by a conventional method from the floor structure F to the roof slab R.

  On the other hand, the upper edge of the face material 13 disposed on the indoor side is located below the ceiling surface level CP defined by the lower surface of the composite panel 20. The separation distance s1 between the ceiling surface level CP and the upper edge of the face material 13 is set to 80 to 120 mm (for example, 100 mm).

  The edge part 20c of the composite panel 20 located in the outer peripheral part (ceiling outer peripheral area) of the ceiling surface is separated from the indoor side surface of the steel stud 11 by a distance s2. In the present embodiment, the separation distance s2 is set to 25 to 50 mm, for example, 35 mm. A support 16 that supports the edge portion 20 c is fixed to the steel stud 11. The support 16 is made of an angle (L-shaped) steel material of 50 mm × 50 mm. The horizontal flange upper surface 16a (FIG. 4B) of the support 16 constitutes a horizontal support surface that supports the lower surface of the edge of the composite panel 20 so as to be horizontally displaceable. The distance s2 is a numerical value determined in relation to the interlayer deformation angle or behavior at the time of the earthquake, and is set to a value such that the edge 20c does not contact the steel stud 11 at the time of the earthquake.

  A metal parting edge 17 is fixed to the steel stud 11 adjacent to the upper edge of the support 16. The parting edge 17 is also made of an angle-shaped (L-shaped) steel material. The face material 18 is fixed to the steel stud 11 above the parting edge 17. The face material 18 is made of, for example, a gypsum board having a plate thickness of 12.5 mm, and extends between the parting edge 17 and the roof slab R. A joint portion or an adjacent portion of the support member 16, the parting edge 17, and the face material 18 is hermetically sealed by a sealing material 19. The construction of the biohazard chamber C is the construction of the face material 18, the airtight treatment of the joints, etc., and the formation of the wall surface on the buffer area D side (the construction of the face materials 13 and 14 and the airtight treatment thereof). This is to improve the safety of the biohazard facility B by forming an auxiliary barrier on the outside of the face material 13 and the composite panel 20 constituting the general barrier.

  As described above, the upper edge of the face material 13 and the lower surface of the composite panel 20 are separated by a separation distance s1 in the vertical direction, and a relatively large separation band (separation space) 4 is formed at the joint between the ceiling and the wall. The The separation band 4 constitutes a surface material separation band in the horizontal direction and the outer periphery of the ceiling that enables relative displacement between the wall structure 1 and the ceiling structure 2.

  A surrounding edge member 50 that closes the separation zone 4 from the indoor side is disposed at the wall / ceiling joint so as to bridge the composite panel 20 and the face material 13. The peripheral edge member 50 is made of a long metal molded member, for example, a long aluminum shape member. The peripheral edge member 50 includes a curved portion 51 having a radius of curvature of about 20 to 50 mm (for example, 30 mm), a horizontal portion 52 extending horizontally from the curved portion 51 to the indoor side, and hanging from the curved portion 51 and horizontally to the outdoor side. It has a base 57 that bends and a vertical substrate 58 that is integrally connected to the base 57. The vertical substrate portion 58 is fixed to the steel stud 11 by a mooring tool such as a screw screw or a fixing tool 60.

As shown in FIG. 4B, the base 57 of the peripheral edge member 50 and the upper end of the face member 13 are separated by a vertical distance t3, and the distance t3 is set to 10 to 20 mm, for example, 15 mm. . Between the base 57 and the face material 13, the backup material 55 and the sealing material 56 are laid or filled in a double layer or two layers, and a sealing material filling joint 53 having a double or double layer structure is formed. The concrete construction method of the joint 53 is as follows.
(1) Insert a backup material 55a having a thickness of about 5 mm into the joint.
(2) The sealing material 56a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) Insert a backup material 55b having a thickness of about 5 mm into the joint.
(4) The sealing material 56b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
A silicon-based sealing material can be preferably used as the sealing material 56.

Further, the horizontal portion 52 of the peripheral edge member 50 and the lower surface of the composite panel 20 are separated by a vertical distance t4, and the distance t4 is set to 30 to 40 mm, for example, 35 mm. A horizontal joint space is formed between the horizontal portion 52 and the composite panel 20. In this horizontal joint space, the backup material 65 and the sealing material 66 are laid or filled in a double or double layer, and a double or double layer sealing material filling joint 63 is formed. The joint 63 has an elastic deformability or a viscoelastic deformability that deforms so as to absorb the relative displacement of the wall structure 1 and the ceiling structure 2. The concrete construction method of the joint 63 is as follows.
(1) A backup material 65a having a thickness of about 5 mm is inserted into the joint.
(2) The sealing material 66a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) A backup material 65b having a thickness of about 5 mm is inserted into the joint.
(4) The sealing material 66b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
As the sealing material 66, a silicon-based sealing material can be preferably used.

  According to such a structure of the ceiling and wall connection portion, since the ceiling structure 1 and the wall structure 2 are separated so as to be relatively displaceable by the separation band 4, if the building shakes during an earthquake, the ceiling structure 1 The body 1 and the wall structure 2 are relatively displaced relative to each other in the separation band 4 (horizontal displacement). A relatively large relative displacement (horizontal displacement) in response to the behavior of the building and the interlayer displacement at the time of the earthquake occurs between the surrounding edge member 50 and the composite panel 20, and this relative displacement is caused by the sealing material 66 of the joint 63. It is substantially absorbed by elastic deformation or viscoelastic deformation.

  In the present embodiment, as the sealing material 66, the design allowable expansion / contraction rate and the design allowable shear deformation rate with respect to the behavior or displacement during an earthquake are 25% or more and 50% or more (preferably 30% or more and 60% or more), respectively. Sealing material is used. The joint width of the hermetic seal structure depends on the horizontal displacement of the ceiling surface level CP based on the interlayer displacement angle of the building set in the structural design, and the design allowable expansion / contraction rate or the design allowable shear deformation rate of the sealing material 66 following this. Is set.

  Thus, the behavior of the building and the inter-layer displacement at the time of the earthquake cause the sealing material 66 of the joint 63 to be relatively greatly deformed, and the seismic force or the excitation force is absorbed or dispersed by the deformation of the joint 63. As a result of reducing the load at the time of earthquake acting on the joints 33, 43, 53 and the wall joints 73, 83, 93 (FIG. 5) etc., the occurrence of breakage, cracks, etc. of the sealing material in these joints is a biohazard chamber. Suppressed in all joints of C.

  In addition, according to the structure of the ceiling / wall joint portion having the above-described configuration, the airtight performance of the joints in the biohazard chamber C can be relatively easily achieved by optimizing the followability of the joints 63 with respect to the behavior of the building or the interlayer displacement. Therefore, the airtight chamber can be partitioned or constructed in the building relatively easily by the dry construction wall structure and ceiling structure.

  FIG. 5 is a cross-sectional view showing the structure of the wall corner V of the wall structure 1, and FIG. 6 is an enlarged cross-sectional view of the vertical joint shown in FIG.

  FIG. 5 shows the structure of the wall corner V of the orthogonal wall structure 1. In the part of the biohazard facility B shown in FIG. 5, biohazard chambers C are formed on both sides of the wall structure 1X in the X direction. The wall structure 1Y in the Y direction forms a buffer area D, a biohazard chamber C, and a boundary wall. The wall structure 1X is connected to the wall structure 1Y at a right angle.

  The rising portions 3 of the wall structures 1X and 1Y are integrated, but the lower runner 12 of the wall structures 1X and 1Y is discontinuous, and the wall structures above the lower runner 12 are independent of each other. The edge 13c of the face member 13 constituting the wall structure 1X is separated from the indoor side surface (wall surface) of the face member 13 constituting the wall structure 1Y by a distance s3, so that a separation band 5 is formed. The separation distance s3 is set to 60 to 100 mm, for example, 80 mm. The separation band 5 constitutes a vertical surface material separation band that enables relative displacement of each wall structure at the connection portion or intersection of the wall structures 1X and 1Y having different wall core directions. A wall corner member 70 that closes the separation zone 5 is attached to the wall corner V from the indoor side so as to bridge the face members 13 of the wall structures 1X and 1Y.

  As shown in FIG. 6, the wall corner member 70 has a curved portion 71 having a curvature radius of about 20 to 50 mm (for example, 30 mm), and extends from the curved portion 71 toward the wall structure 1X and is perpendicular to the stud side (outdoor). An extended portion 72 that is bent to the wall structure 1 </ b> Y side, and a base portion 74 that is bent at right angles to the stud side (outside), and a vertical substrate portion 77 that is integrally connected to the base portion 74. Have The substrate part 77 is fixed to the steel stud 11 by a mooring tool such as a screw screw or a fixing tool 80. On the other hand, the extended portion 72 of the wall corner member 70 bent toward the inside of the wall body is further bent at the bent portion 79 having a form capable of positioning the sealing backer member 87 and ends.

  The bent portion 79 is bent in a key shape in the X direction and the Y direction, and is separated from each surface of the steel stud 11 by distances s4 and s5 in the X direction and the Y direction. The backer member 87 is held by the bent portion 79. The backer member 87 is made of an elastically deformable resin foam, and defines a filling area of the sealing material 86 (86a) in cooperation with the backup material 85 (85a). As will be described later, the bent portion 79 is for preventing the steel stud 11 and the wall corner member 70 from physically interfering with each other due to the relative displacement of the wall structures 1X and 1Y during an earthquake.

The extension part 72 of the wall corner member 70 is separated from the face material 13 of the wall structure 1X, and the separation distance t5 is set to 30 to 40 mm, for example, 35 mm. The edge 13c of the face material 13 is fixed to the steel stud 11 by a mooring tool such as a screw screw or a fixture 81, and between the extended portion 72 and the backer member 87 and the edge 13c of the face material 13. A vertical joint space is formed. In this vertical joint space, the backup material 85 and the sealing material 86 are laid or filled in a double or double layer, and the double or double layer sealing material filling joint 83 is formed between the wall corner member 70 and the face material 13. Formed between. The concrete construction method of the joint 83 is as follows.
(1) Insert a backup material 85a having a thickness of about 5 mm into the joint.
(2) The sealing material 86a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) Insert a backup material 85b having a thickness of about 5 mm into the joint.
(4) The sealing material 86b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
As the sealing material 86, a silicon-based sealing material can be preferably used.

  In the present embodiment, as the sealing material 86, the design allowable expansion / contraction rate and the design allowable shear deformation rate with respect to the behavior or displacement during an earthquake are 25% or more and 50% or more (preferably 30% or more and 60% or more), respectively. Sealing material is used. The joint width of the hermetic seal structure is the relative displacement of the wall structures 1X and 1Y based on the interlayer displacement angle of the building set in the structural design, and the design allowable expansion / contraction rate or the design allowable shear deformation rate of the sealing material 86 that follows the relative displacement. And set by

Further, the base 74 of the wall corner member 70 and the face material 13 of the wall structure 1Y are also separated from each other, and the separation distance t6 is set to 10 to 20 mm, for example, 15 mm. A vertical joint space is formed between the base portion 74 and the edge portion 13 c of the face material 13. In this vertical joint space, the backup material 75 and the sealing material 76 are laid or filled in two or two layers, and the double or two-layered sealing material filling joint 73 is formed between the wall corner member 70 and the face material 13. Formed between. The concrete construction method of the joint 73 is as follows.
(1) Insert a backup material 75a having a thickness of about 5 mm into the joint.
(2) The sealant 76a is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
(3) Insert a backup material 75b having a thickness of about 5 mm into the joint.
(4) The sealing material 76b is injected or filled into the joint to a thickness of about 10 to 15 mm (for example, 12 mm).
As the sealing material 76, a silicon-based sealing material can be preferably used.

  FIG. 5 shows a sealing material filling joint 93 on the wall surface connecting the face materials 13 together. Similar to the sealing material filling joint 73, the sealing material filling joint 93 has a joint structure in which a backup material and a sealing material are inserted or filled into a vertical joint space in a double or two-layer structure.

  According to the structure of the entering corner (wall corner V) configured as described above, the wall structures 2 are separated from each other by the separation band 5 so as to be relatively displaceable. The bodies 2 are relatively displaced relative to each other in the separation zone 5 without being constrained to each other. A relatively large relative displacement in response to the behavior of the building and the inter-layer displacement at the time of the earthquake occurs between the wall corner member 70 and the face material 13, and this relative displacement is caused by elastic deformation or viscosity of the sealing material 86 of the joint 83. Absorbed by elastic deformation.

  In addition, when the wall structures 1X and 1Y are relatively displaced in the X direction or the Y direction, there is no possibility that the wall corner member 70 and the steel stud 11 interfere with each other at the time of displacement, but the wall structures 1X and 1Y are in the X direction. Or, when the relative displacement is made in the middle angle direction of the Y direction (for example, the direction of the angle of 45 degrees indicated by the broken arrow in FIG. 6), the corner portion of the steel stud 11 interferes with the wall corner member 70, particularly near the ceiling. Concerned about the situation. However, since the bent portion 79 forms a clearance that secures the behavior area of the corner of the steel stud 11 in order to avoid such interference, the interference between the wall corner member 70 and the steel stud 11 is It can be surely prevented. The separation distances s4 and s5 of the bent portion 79 with respect to each surface of the steel stud 11 should be set for each building according to the behavioral characteristics of the building and the interlayer displacement at the time of the earthquake. It may be desirable to set it to a value.

  Therefore, the behavior of the building and the interlayer displacement at the time of the earthquake cause the sealing material 86 of the joint 83 to be relatively greatly deformed, and the seismic force or the excitation force is absorbed or dispersed by the deformation of the joint 83. As a result of reducing the load at the time of earthquake acting on 33, 43, 53, 63, 73, 93, etc., the occurrence of breakage, cracks, etc. of the sealing material at these joints is suppressed in the joints of the biohazard chamber C in general. .

  Further, according to the structure of the wall corner V, the airtight performance of the joints in the biohazard chamber C can be relatively easily ensured by optimizing the followability of the joints 83 with respect to the behavior of the building or the interlayer displacement. Therefore, it is possible to partition or construct a highly airtight chamber in a building relatively easily by the wall structure and ceiling structure of the dry construction method.

  Furthermore, according to such a structure of the wall corner V, the face material 13 and the wall corner member 70 of the wall structure 1X are structurally separated by the sealing material filling joint 83, and the mutual stress transmission is cut off. Is done. Accordingly, the shearing stress acting on the wall structure 1X or the shearing stress acting on the wall structure 1X due to the earthquake acceleration is insulated by the sealing material filling joint 83, and is not transmitted to the wall structure 1Y. The shear stress acting on the wall structure 1Y due to the seismic force or seismic acceleration acting on 1Y is also insulated by the sealing material filling joint 83 and is not transmitted to the wall structure 1X. Therefore, the seismic performance of each of the wall structures 1X and 1Y can be designed as desired. For example, the seismic resistance and airtightness of the partition wall (wall structure 1X) between the biohazard chambers C and the seismic resistance and airtightness of the boundary wall (wall structure 1Y) of the biohazard facility B are individually designed. It becomes possible.

  Further, the joints 23, 33, 43, 53, 63, 73, 83, 93 of the biohazard chamber C have a double or two-layer sealing in which a backup material and a sealing material are laid or filled in two or two layers. Since it is a material-filled joint, its airtight performance can be maintained and managed by replacing only the indoor sealing material, which is relatively easily deteriorated, at an early stage. For example, in the indoor space of the biohazard chamber C, sterilization, disinfection or decontamination with formalin, hydrogen peroxide, or the like is performed relatively frequently. Sealing that deteriorates or deteriorates due to the action of such a sterilizing solution or the like. Since the material is limited to the indoor sealing material, the airtight performance of the airtight seal structure can be maintained and managed relatively easily by exchanging the material.

However, the present invention is not limited to the above-described embodiments, and various changes or modifications can be made within the scope of the present invention described in the claims. Needless to say, such modifications or variations are also included in the scope of the present invention.

  For example, although the said embodiment is related to a biohazard facility, you may apply this invention to the division structure or the division method of the high airtight space of other functions and uses, such as a clean room.

  Further, the wall structure according to the above embodiment has a structure using a lightweight steel stud and a runner for light iron (LGS) wall base (JIS A 6517-2010: steel base material for construction). There may be a wall structure using a wall stud of another configuration, for example, a steel stud (JIS A 6517-2010: steel foundation material for construction) as a stud for a light iron (LGS) wall foundation. .

  Furthermore, the ceiling structure according to the above embodiment is configured to support the ceiling surface material by a T-bar-shaped field edge, but a light iron ceiling foundation (JIS A 6517-2010: steel foundation material for construction) A ceiling structure using a ceiling base of another structure such as the above may be used.

  In addition, in the above embodiment, the depth dimension (joint depth) for the double seal structure is ensured by using a heat insulating panel or a composite panel as a ceiling and wall face material. By means, the depth dimension of the joint (joint depth) may be secured. In the above embodiment, the light weight or workability at the time of construction is emphasized, and the reduced composite panel is adopted as the wall surface material. However, the fire resistance or fire resistance is emphasized, and a relatively heavy gypsum board or the like is used. You may employ | adopt a face material or its composite surface material as a wall surface material.
