  Since all of the assembly booths described in Patent Documents 1 to 4 have many types of constituent members, a large amount of labor and time are required for carrying in and assembling to the installation site. It is also difficult to change the internal space according to the size of the installation site and usage conditions.

  On the other hand, the assembly booths described in Patent Documents 2, 3 and 4 are all equipped with an air conditioner, but in the case of the assembly booth described in Patent Document 2, the air conditioner is only installed on the wall surface in the booth. Air conditioning unevenness is likely to occur and air conditioning efficiency is poor. In addition, in the case of the assembly booths described in Patent Documents 3 and 4, since the ventilation path for circulating the conditioned air supplied from the air conditioner is complicated, a great deal of labor is required during assembly and movement at the installation site. Cost. Moreover, it is difficult to change the arrangement of the air conditioner and the ventilation path according to the situation of the installation site.

  The problem to be solved by the present invention is to provide an assembly booth that has an air conditioning function, is easy to carry in and assemble to the installation site, can change the internal space, and can also change the arrangement of the air conditioner and the ventilation path. It is to provide.

An assembly booth according to the present invention includes a lattice structure body assembled by detachably fixing the end faces of a plurality of bar members having the same cross-sectional shape to the outer peripheral surface of another bar member via a connector, and the lattice structure body A lattice structure sub-body formed by using the bar and the connector along at least a part of an upper surface and an outer peripheral surface; and a plurality of the lattice structure main body and the lattice structure sub-body surrounded by the bar A panel material detachably fitted in the region,
In the lattice structure sub body, an air conditioner, and an air supply device that blows air into the lattice structure body from the boundary between the upper surface of the lattice structure body and the lattice structure sub body, and an outer peripheral surface of the lattice structure body, A communication port is provided at a boundary with the lattice structure sub-body.

  With such a configuration, a plurality of bars having the same cross-sectional shape are combined vertically and horizontally, and the end surface of the bar is fixed to the outer peripheral surface of another bar using a connector, and the lattice structure main body and the lattice structure sub body An air conditioner is disposed in the lattice structure sub-body, and air blowing means into the lattice structure main body is provided at a boundary surface between the upper surface of the lattice structure main body and the lattice structure sub-body, and the lattice structure main body An assembly booth can be constructed simply by providing a communication port at the boundary surface between the outer peripheral surface of the grid structure and the substructure of the lattice structure and fitting the panel material into the region surrounded by the bar material.

  In addition, the conditioned air whose temperature is adjusted by the air conditioner arranged in the lattice structure sub-body is sent into the lattice structure main body by the air supply device, and the air in the lattice structure main body is connected to the lattice structure sub-body via the communication port. Since the air-conditioning system in which the lattice structure sub-body functions as a blower duct is formed, the highly efficient air-conditioning effect can be obtained.

  Since the constituent members of the assembly booth are rods, connectors and panel members having the same cross-sectional shape, they can be easily carried into the installation site and assembled. In addition, since the size and shape of the lattice structure main body can be changed by increasing / decreasing the number of bars, the internal space can be changed. Furthermore, since the position of the lattice structure sub-body with respect to the lattice structure main body can be changed, the arrangement of the air conditioner and the ventilation path can also be changed.

  Here, if an air supply / exhaust port having a channel opening / closing means is provided on the outer surface of the lattice structure sub-body, the outside air can be introduced into the lattice structure sub-body or the air inside the lattice structure sub-body can be discharged to the outside. Therefore, air conditioning suitable for use conditions can be performed. In this case, if a blower fan is provided at the air supply / exhaust port, forced air supply / exhaust can be performed, so that the atmospheric pressure in the lattice structure body can be adjusted. In addition, the positive pressure inside the grid structure body prevents inflow of outside air containing dust, and conversely, negative pressure removes harmful substances generated in the grid structure body and discharges them. You can also.

  On the other hand, an exhaust port having a skirt-shaped opening / closing member may be provided on the outer peripheral surface of the lattice structure main body. With such a configuration, the air in the lattice structure body can be discharged to the outside via the exhaust port having the skirt-shaped opening and closing member, so that unclean external air flows into the lattice structure body. Exhaust can be performed while preventing this.

  In the assembly booth of the present invention, at least one of the panel members can be formed of a light transmissive member. With such a configuration, it becomes possible to incorporate external light into the assembly booth and visually check the inside of the assembly booth.

  On the other hand, it is desirable to provide locking means to which the connector can be attached and detached on both end faces and the outer peripheral face of the bar. With such a configuration, the fixing work between the end face and the outer peripheral surface of the bar can be made more efficient, and the disassembly work can be facilitated. Change work is also easy.

Here, as the locking means, on the outer peripheral surface of the bar material, a locking groove having a shape whose inside is wider than the opening is provided in parallel with the axis of the bar material, and female ends are provided on both end surfaces of the bar material. Provide the screw part,
As the coupling tool, a coupling member having a stopper portion slidably held in the locking groove of the bar, and slidable on the coupling member to be screwed into the female screw portion of the end surface of the bar It is preferable to use a connecting bolt inserted through the connecting bolt and a fixing bolt screwed into the connecting member to press the lower surface of the head of the connecting bolt by a screw tightening operation. With such a configuration, it becomes possible to fix the end face of another bar at an arbitrary position on the outer peripheral surface of the bar, and the fixing work is facilitated.

  In addition, if the outer periphery of the panel is inserted into the locking groove on the outer peripheral surface of the bar, the panel member to be fitted in the region surrounded by the bar can be securely fixed by a simple operation. Become. In addition, since the outer periphery of the panel material is held in the locking groove, it is difficult for the panel material to be bent, so that a relatively thin panel material can be used, and the component members can be reduced in weight. .

  According to the present invention, it is possible to provide an assembly booth that has an air conditioning function, can be easily carried into an installation site, can be assembled, can change an internal space, and can also change the arrangement of an air conditioner and a ventilation path.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front perspective view showing an assembly booth according to an embodiment of the present invention, FIG. 2 is a rear perspective view of the assembly booth shown in FIG. 1, FIG. 3 is a front view of the assembly booth shown in FIG. Is a plan view of the assembly booth shown in FIG. 1, FIG. 5 is a rear view of the assembly booth shown in FIG. 1, FIG. 6 is a side view of the assembly booth shown in FIG. It is a schematic diagram.

  As shown in FIGS. 1 to 7, the assembly booth 10 according to this embodiment is configured such that the end surfaces of a plurality of bar members 11 b and 11 c having the same cross-sectional shape are connected to another bar member 11 a via a connector 26 (see FIG. 8). The lattice structure main body 10a assembled to be detachably fixed to the outer peripheral surface of the steel plate, and the bar members 11a, 11b, 11c and the connecting tool along the upper surface 10u of the lattice structure main body 10a and the back surface 10r forming a part of the outer peripheral surface. And a plurality of lattice structure sub-body 10b formed by using the H. 26 and removably fitted in a plurality of regions surrounded by the bars 11a, 11b, and 11c in the lattice structure main body 10a and the lattice structure sub-body 10b. Panel members 14 and 15.

  The assembly booth 10 has a box shape in which a portion excluding the floor portion is surrounded by a plurality of surfaces, and a door 27 and an auxiliary door 28 are arranged at the center of the front portion. A support leg 13 having an adjustable height is attached to the lower ends of the plurality of bars 11a arranged in the vertical direction, and a gap S is formed between the horizontal bar 11b positioned at the bottom and the floor surface F. Is provided. The door 27 can be opened and closed when a person or an object enters or exits, and the auxiliary door 28 can be opened when it is desired to widen the entrance.

  In the lattice structure sub-body 10b, an air conditioner 23 and an air supply device 12 that blows air into the lattice structure main body 10a from the boundary between the upper surface 10u of the lattice structure main body 10a and the lattice structure sub-body 10b are disposed. A communication port 24 is provided at the boundary surface between the back surface 10r and the lattice structure sub-body 10b, which is the outer peripheral surface of the main body 10a. The communication port 24 is provided with a channel opening / closing means 24a. The air conditioner 23 is held in a state of being hung on the ceiling portion of the lattice structure sub-body 10b near the back surface 10r.

  An air supply / exhaust port 25 having a flow path opening / closing means 25a is provided on a back surface portion forming a part of the outer surface of the lattice structure sub-body 10b. An exhaust port 29 communicating with the atmosphere is provided in a front portion that forms part of the outer peripheral surface of the lattice structure main body 10a. The exhaust port 29 is provided with a skirt-shaped opening / closing member 29 a that opens and closes the exhaust port 29. In addition, among the plurality of regions surrounded by the bars 11a and 11b, the panel member 14 fitted in the region from the lowest level to the third level close to the floor surface F is formed of a light-impermeable member. The other panel material 15 is formed of a transparent member.

  The air supply device 12 incorporates an electric fan and a filter (not shown), and as shown in FIG. 7, the air sucked from the lattice structure subbody 10b of the assembly booth 10 is filtered into the lattice structure body 10a. It has a function to supply. The conditioned air whose temperature has been adjusted by the air conditioner 23 and supplied into the lattice structure sub-body 10b is filtered by the air supply device 12, and from the lower surface of the air supply device 12 located on the upper surface 10u of the lattice structure body 10a to the floor surface F ( (See FIG. 3). The air in the assembly booth 10 is discharged into the lattice structure sub-body 10b through the communication port 24, adjusted in temperature by the air conditioner 23, filtered again by the air supply device 12, and sent into the assembly booth 10. . A part of the air in the assembly booth 10 passes through the clearance S (see FIG. 3) between the horizontal bar 11b located at the lowermost part of the lattice structure main body 10a and the floor F or the exhaust port 29. It is discharged outside.

  Thus, the conditioned air whose temperature is adjusted by the air conditioner 23 arranged in the lattice structure sub-body 10b is sent into the lattice structure body 10a by the air supply device 12, and the air in the lattice structure body 10a is connected to the communication port. 24 is discharged into the lattice structure sub-body 10b via 24, an air conditioning system is formed in which the lattice structure sub-body 10b functions as a blower duct. Since the air adjusted by the air conditioner 23 is circulated, highly efficient air conditioning can be performed, and energy consumption can be reduced. Further, since the air purified by the filter built in the air supply device 12 is circulated, the life of the filter in the air conditioner 23 can be extended. Furthermore, since the skirt-shaped opening / closing member 29a provided in the exhaust port 29 is opened to the outside by the atmospheric pressure in the lattice structure body 10a, external air that has not been cleaned flows into the lattice structure body. Exhaust can be performed while preventing this.

  By changing the opening degree of the flow path opening / closing means 24a and 25a provided at the communication port 24 and the air supply / exhaust port 25, the amount of air circulated between the lattice structure main body 10a and the lattice structure sub body 10b and the supply / exhaust air You can adjust the air volume. For this reason, it is possible to circulate air while maintaining the inside of the lattice structure main body 10a at a positive pressure or an atmospheric pressure, and an air-conditioning state suitable for the use conditions can be obtained. In this case, if a blower fan is provided at the air supply / exhaust port 25, forced air supply and exhaust can be performed, so that the atmospheric pressure in the assembly booth 10 can be adjusted, and the interior of the lattice structure main body 10a is negative. The pressure can also be maintained. If the inside of the lattice structure main body 10a is maintained at a positive pressure, inflow of outside air containing dust can be prevented, and if maintained at a negative pressure, harmful substances generated in the lattice structure main body 10a can be removed and discharged. . Further, a chemical filter or a deodorizing filter can be installed at the air supply / exhaust port 25. In addition, since the air conditioner 23 is not specifically limited, For example, the air conditioner for general houses can also be used.

  Next, the assembly procedure of the assembly booth 10 will be described based on FIGS. 8 is a perspective view showing a procedure for assembling the bars constituting the assembly booth shown in FIG. 1, FIG. 9 is a perspective view showing the procedure for assembling the bars constituting the assembly booth shown in FIG. 1, and FIG. The schematic diagram which shows the fixed state of a bar, FIG. 11 is a fragmentary sectional view which shows the attachment structure of the panel material with respect to a bar.

  As shown in FIGS. 8 to 10, the cross-sectional shapes of the bars 11a, 11b, and 11c are all substantially square, the through hole 19 is provided in the axial center portion, and the through holes 22 are provided in the four corner portions, Female screw portions 19 a (see FIG. 10) are formed at both end portions of the through hole 19. Further, locking grooves 20 that are parallel to the axial direction are formed in the four flat portions on the outer periphery of the rods 11a, 11b, and 11c. Rail portions 20c and 20c projecting in the width-reducing direction are provided on both sides of the opening 20a of the locking groove 20, and the inside 20b is wider than the opening 20a. The female threaded portions 19a on both end faces of the bar members 11a, 11b, and 11c and the locking groove 20 on the outer peripheral surface serve as locking means for attaching and detaching a connecting tool 26 described later.

  As shown in FIGS. 8 and 10, the connecting tool 26 includes a connecting member 17 having a pair of stopper portions 17a and 17a that are slidably held in the locking groove 20 of the bar 11a, and an end surface of the bar 11a. A connecting bolt 16 slidably inserted into the connecting member 17 to be screwed into the female screw portion 19a, and a fixing bolt 18 screwed into the connecting member 17 to press the bottom surface of the head 16a of the connecting bolt 16. It has. The connecting member 17 is attached to the end surface of the bar 11b with a connecting bolt 16 screwed into the female screw portion 19a slidably inserted through the through hole 17b. Stoppers 17a, 17a are provided that are slidably held in the locking grooves 20 of the bar 11a. As shown in FIG. 9, the fixing bolt 18 can be tightened or loosened from a position facing the opening 20a of the locking groove 20 of the bar 11b, and can press the lower surface of the head 16a of the connecting bolt 16 by screw tightening rotation. In this state, it is screwed to the connecting member 17.

  Here, based on FIGS. 8-10, the procedure which fixes the end surface of the bar 11b to the outer peripheral surface of the bar 11a is demonstrated. As shown in FIGS. 8 and 10, the male threaded portion 16b of the coupling bolt 16 of the coupling tool 26 is screwed into a female threaded hole (not shown) at the center of the end surface of the bar 11b, so that the coupling member 17 does not move. After tightening to the end, the connecting bolt 16 is loosened about one turn. Next, as shown in FIG. 9, the stoppers 17 a and 17 a of the connecting member 17 are placed in the locking groove 20 of the bar 11 a, and the connecting member 17 is inserted into the locking groove 20. Then, after determining the positional relationship between the bar 11a and the bar 11b as shown in FIG. 10, as shown in FIG. 9, the tool T is moved obliquely upward from the opening 20a of the locking groove 20 of the bar 11b. Then, the fixing bolt 18 is rotated in the tightening direction.

  As a result, as shown in FIG. 10, the tip 18a of the fixing bolt 18 gradually presses the lower surface of the head 16a of the connecting bolt 16, so that the connecting member 17 moves away from the head 16a relatively. As a result of the movement and the lower surfaces of the stopper portions 17a and 17a pressing the rail portions 20c and 20c toward the end surface of the bar 11b, the outer peripheral surface of the bar 11a is fixed to the end surface of the bar 11b. In addition, since the positional relationship between the bar 11a and the bar 11b is not limited to the L shape, the bar 11a and the bar 11b can be attached so as to form a T shape.

  Next, with reference to FIG. 11, the attachment structure of the panel materials 14 and 15 with respect to the bar 11a is demonstrated. As shown in FIGS. 1 to 6, the panel members 14 and 15 fitted in the regions surrounded by the bars 11 a, 11 b, and 11 c have the outer peripheral portions thereof together with the packings 36 as shown in FIG. 11. It is attached by being inserted into the locking groove 20 such as 11a. The packing 36 is disposed on one side of the outer peripheral portion of the panel members 14 and 15, and is fitted into the locking groove 20 with one rail portion 20c of the opening 20a of the locking groove 20 held between the groove portions 36a. Yes.

  In this way, the assembly booth 10 combines a plurality of bars 11a, 11b, and 11c having the same cross-sectional shape vertically and horizontally, and uses the connector 26 to make the end surfaces of the bars 11b and 11c the outer peripheral surface of the other bars 11a. The lattice structure main body 10a and the lattice structure sub-body 10b are formed by being fixed, and the panel members 14 and 15 are simply fitted into the regions surrounded by the bars 11a, 11b, and 11c, so that the structure can be constructed very easily. it can. Since the constituent members are the rods 11a, 11b, and 11c having the same cross-sectional shape, the connector 26, and the panel members 14 and 15, the carrying-in and assembly to the installation site are easy. Further, by increasing or decreasing the number of the bars 11a, 11b, and 11c, the size and shape of the lattice structure main body 10a and the lattice structure sub body 10b can be changed, and the space in the assembly booth can be changed.

  In this embodiment, as shown in FIGS. 1 and 2, the lattice structure sub-body 10b is arranged from the front to the back at the center of the upper surface 10u of the lattice structure main body 10a, and extends from the rear edge of the upper surface 10u to the back. However, the present invention is not limited to this, and the lattice structure sub-body 10b can be formed and arranged in a position and size suitable for the use conditions.

  Further, since the panel material 15 formed of a translucent member is disposed in the upper part of the lattice structure main body 10a and the lattice structure sub-body 10b, external light (such as illumination light in the building) is transmitted into the assembly booth 10. Or the state inside the assembly booth 10 can be visually confirmed.

  Furthermore, as a locking means for the connector 26, a female thread portion 19a is provided on the end face of the bar 11a, 11b, 11c, and a locking groove 20 is provided on the outer peripheral surface. For this reason, the fixing work between the end face of the bar 11b and the outer peripheral surface of the bar 11a can be made more efficient, and the disassembly work can be facilitated. Is also easier. In addition, since the arrangement | sequence state of the panel materials 14 and 15 is not limited to what is shown in FIGS. 1-6, it can change according to use conditions.

  On the other hand, by using the connector 26 as shown in FIGS. 8 and 9, the end surfaces of the other bars 11a, 11b, and 11c are fixed at arbitrary positions on the outer peripheral surfaces of the bars 11a, 11b, and 11c. Therefore, fixing work is also easy. Further, the connecting tool 26 is not exposed at the connecting portions of the bar members 11a, 11b, and 11c, and cannot be easily seen from the outside. Furthermore, as shown in FIG. 11, the outer peripheral portions of the panel members 14 and 15 are fitted in the locking grooves 20 with the packing 36 attached, so that the regions surrounded by the bars 11 a, 11 b and 11 c The panel members 14 and 15 to be fitted inside can be securely fixed by a simple operation. In addition, as a result of the outer peripheral portions of the panel members 14 and 15 being fixedly held in the locking groove 20, the panel members 14 and 15 are less likely to be deformed, so that relatively thin panel members 14 and 15 can be used. Thus, the weight of the constituent members can be reduced.

  Next, with reference to FIG. 12, FIG. 13, the structure which connects a bar in a longitudinal direction is demonstrated. FIG. 12 is a perspective view showing an extension connector, and FIG. 13 is a perspective view showing a connecting state of bars using the extension connector shown in FIG.

  By using the extension connector 30 as shown in FIG. 12, the two bars 11x and 11y can be connected in the longitudinal direction as shown in FIG. The extension connector 30 includes a main body 30a that can be inserted into the locking groove 20 of the bar 11x, 11y and two fixing bolts 31. The main body portion 30 a is provided with a female screw hole 30 c for screwing the fixing bolt 31 and a pair of stopper portions 30 b for engaging the main body portion 30 a with the inner surface of the rail portion 20 c in the locking groove 20. ing.

  As shown in FIG. 13, the extension connector 30 in a state where the fixing bolt 31 is screwed into the female screw hole 30c is inserted into the locking groove 20 of the bar members 11x and 11y, and the connecting portion of the bar members 11x and 11y is inserted. Arrange to straddle. When a tool (not shown) is inserted from the opening 20a of the locking groove 20 and the fixing bolt 31 is tightened, the tip 31a of the fixing bolt 31 presses the bottom of the locking groove 20, and the reaction force thereof. Thus, since the stopper portion 30b of the main body portion 30a approaches the rail portion 20c and finally comes into close contact with the inner surface of the rail portion 20c, the extended connector 30 is fixed in the locking groove 20. As a result, the two bars 11x and 11y are connected so as not to leave.

  In this way, by using the extension connector 30, it is possible to form a long bar by connecting the two bars 11x and 11y in the longitudinal direction. Even when a bar longer than the length of the bar 11x, 11x is required, it can be easily handled.
