JP-A-6-33608 (Claim 2, paragraphs 0008 to 0023, FIGS. 1 to 11) JP 2002-235443 A (Claim 1, paragraphs 0014 to 0020, FIGS. 1 to 12) JP-A-6-81475 (Claim 1, paragraphs 0011 to 0024, FIGS. 1 to 18) JP-A-10-37307 (Claim 1, paragraphs 0009 to 0024, FIGS. 1 to 5, FIGS. 7 to 12) JP-A-8-113986 (Claim 1, paragraphs 00121 to 0014, FIGS. 1, 3, and 4)

  In Patent Documents 2 and 3 in which the roof frame is constructed on the track using the roof unit including the truss frame among the above prior arts, after the truss frame or the like constituting a part of the roof unit is suspended on the track, A roof unit that can run on a track is assembled, and the roof unit is run every time it is assembled. This is because the roof unit is lifted in units of components (truss frames) and the final assembly is performed on the track, so the lifting machine does not require high capacity and the lifting efficiency is good. it is conceivable that.

  However, in the final assembly method on the track, the structural member (truss frame) must be kept suspended until the roof unit is secured to be able to run on the track. Therefore, the roof unit cannot be driven until the completion of one roof unit. For this reason, until the roof unit can travel, it is necessary to go through a plurality of steps of making the component members stand on the track and assembling the roof unit by connecting the component members. May be reduced.

  In the final assembly method including finishing of the roof unit on the track, it is indispensable to assemble scaffolds on both the outer side and the inner side of the roof frame in the beam direction. Here, when the roof frame is installed on the wall facing in the direction between the beams, it is necessary to assemble the scaffold to a height exceeding the top of the wall. The time (period) required for dismantling cannot be ignored.

  The present invention is based on the above background, and in the method of constructing a roof frame using a pre-laid track, the work on the track is simplified, and in particular, the construction method and the method for simplifying assembly / disassembly of the scaffold are used. Proposed movement prevention device and lift prevention device are proposed.

The construction method of the roof frame of the invention according to claim 1 is:
Column members facing in the beam-to-beam direction and parallel in the column direction, beam members laid between the column members in parallel in the column direction, and truss members laid between the column members facing in the beam direction and facing the beam direction Manufacturing the inner roof unit and the outer roof unit in a self-supporting form as a three-dimensional truss using
The inner roof unit is installed between the walls facing each other in the beam direction. The inner track that runs continuously in the direction of the beam and is parallel to the beam direction and the outer track that is located outside the beam in the beam direction. And placing on the inner track,
Laying the outer roof unit between the opposing walls and placing it on the outer track; and
Each time the inner roof unit is installed between the opposing walls, it is moved in the row direction, and the operation of connecting the adjacent inner roof units to each other is repeated to form an inner roof frame structure movable in the row direction,
Each time the outer roof unit is installed between the opposing walls, the outer roof unit is moved in the row direction, and the operation of connecting the adjacent outer roof units to each other is repeated to form an outer roof structure movable in the row direction. seen including,
The step of configuring the inner roof frame is preceded by the step of configuring the outer roof frame .

  The inner (outer) roof unit is placed on the inner (outer) track with the inner roof unit and outer roof unit being manufactured as a three-dimensional truss before being suspended on the wall, with the three-dimensional truss being bent in advance. The position of the leg portion of the column member can be secured (determined) at the time of placement. Accordingly, unnecessary stress is not generated on the inner (outer) roof unit and the track as in the case where the inner (outer) roof unit is constructed on the track and the deflection is generated on the inner (outer) roof unit.

  Either the process of laying the inner roof unit (constructing the inner roof frame) or the process of laying the outer roof unit (constructing the outer roof frame) can be preceded. It may be preceded by erection.只 When all roof frames are closed, a part of the inner roof frame and the part of the outer roof frame adjacent to each other in the row direction overlap, and the outer roof frame is the upper side of the inner roof frame in the overlapping part. Since the outer roof frame is located on the (outside) and covers the inner roof frame, it is advantageous to precede the inner roof frame.

  According to the method of preceding the step of constructing the inner roof unit (constructing the inner roof frame), the inner roof frame that overlaps the indoor side when the outer roof unit is constructed or when the outer roof frame is constructed. Since the work can be performed by using, it is not necessary to construct the scaffold at least inside the opposite wall, that is, indoors, or the scaffold can be simplified.

In this case, the process building roof Frames are constituting the inner roof rack structure, by Rukoto is preceded steps constituting the outer roof rack structure, in the process of constituting the outer roof rack structure, the finished inner roof rack structure the while using as a scaffold, is made possible to configure the outer roof rack structure. Specifically, the inner roof frame is used to perform wiring work, piping and other equipment arrangements on the entire roof frame, and finish work on the indoor side of the outer roof frame.

  By using the inner roof frame that has been completed in advance, it is possible to construct the outer roof frame including the connection of the outer roof units. Therefore, the time (period) required to assemble and disassemble the indoor scaffolding can be greatly shortened, and the construction period can be shortened in terms of temporary construction.

  Further, in the step of constructing the inner roof frame and the step of configuring the outer roof frame as claimed in claim 2, the inner roof frame and the outer roof frame are assembled by using an external scaffold assembled on the outside of the walls facing each other in the beam direction. If the outer roof frame is finished, it is possible to complete the construction on at least the inner roof frame and the surface side (outdoor side) of the outer roof frame.

  By completing the construction work on the front side of the inner roof frame and the outer roof frame in advance, it is possible to carry out the indoor work without being affected by the weather. The work period can be shortened.

  The inner roof unit and the outer roof unit are manufactured in a self-supporting form as a three-dimensional truss on the ground. Since the outer roof unit is located on the outer peripheral side of the inner roof unit and covers the inner roof unit, the outer roof unit is larger than the inner roof unit. Rolls on the track to the lower end of the inner roof unit and the outer roof unit, etc., from the production of the inner roof unit and the outer roof unit on the ground to the inner movement or suspension on the outer track. Wheels are connected.

  The inner track and the outer track are laid on the upper layer of the wall, such as the top of the wall, and the outer track is positioned on the outer side in the interbeam direction with respect to the inner track. The inner track and the outer track may be arranged at the same level or may be arranged with a step.

  When the inner roof unit and the outer roof unit are self-supporting as a three-dimensional truss at the time of hanging on the inner track or on the outer track, and the wheels are connected to the lower end, the inner roof unit and It is possible to run the outer roof unit from the time when it is installed between the opposing walls and placed on the inner track and the outer track. At the same time, the suspension support by the lifting machine is released after the suspension on the track.

  The inner roof frame is configured by connecting a plurality of inner roof units laid between opposing walls, and the outer roof frame is similarly configured by connecting a plurality of outer roof units to each other. Composed. Since the inner roof unit and the outer roof unit can move along the inner track and the outer track, the inner roof frame and the outer roof frame, which are connected to each other, also move along the inner track and the outer track. Is possible.

  The inner (outer) roof units adjacent to each other in the crossing direction are connected in contact with each other, and a connecting material and brace constructed between the inner (outer) roof units are connected to each other at a distance. To form an inner (outer) roof frame. The outer roof frame is located on the outdoor side of the inner roof frame.

  Since the lifting support by the lifting machine can be released after the inner (outer) roof unit is suspended on the track, the use efficiency of the lifting machine used for the lifting of the inner (outer) roof unit is improved. In addition, since the inner (outer) roof unit can be connected to the inner (outer) roof unit that has been suspended in advance from the time when it is suspended on the track, there is a stagnation in the progress of work on the track. It does not occur.

  The hoisting machine needs only to repeatedly suspend the inner (outer) roof unit assembled on the ground to the track, and on the track, the adjacent inner (outer) roof unit from the point of suspension of the inner (outer) roof unit. Since it is possible to shift to a connection work between the two, the work efficiency on the track is improved together with the use efficiency of the lifting machine. On the ground, the work of assembling the inner (outer) roof unit may be performed in accordance with the work time from the lifting to lifting of the lifting machine. As a result, the period until the completion of the construction of the inner (outer) roof frame is shortened, and in addition to the simplification of the scaffold, the construction period can be shortened as a whole.

  Since the inner (outer) roof unit can run on the track by connecting the wheels from the time it is assembled on the ground, the inner (outer) roof frame constructed on the track can also run freely on the track. is there. The inner (outer) roof unit to which the wheels are connected can travel on the track, so that the inner (outer) roof unit is connected to each other and the inner (outer) roof frame is completed. It is necessary to constrain the inner (outer) roof unit to the wall so that the inner (outer) roof unit does not run freely from the inside safety aspect.

Then, the movement prevention apparatus of Claim 3 is installed in the leg part of the inner side (outer side) roof unit to which a wheel is connected as a means to restrain the movement. For example, when the track is shaped to protrude upward from the top of the wall (in the case of a rail having an I-shaped cross section), the movement preventing device is disposed on both sides in the running direction of the legs of the inner (outer) roof unit, and the inner (outer) ) A stop member fixed to the wall in a state of straddling the track, and a contact member fixed in a state of being able to contact the stop member on both sides in the traveling direction of the legs of the inner (outer) roof unit . The stop members are arranged on both sides of the leg when the inner (outer) roof unit is in a position to be stationary.

The anti-movement device is opposed to the beam-to-beam direction, and is installed between the column members that are arranged in parallel in the column direction, the beam members that are installed between the column members that are arranged in parallel in the column direction, and the column members that are opposed in the direction of the beam. Producing an inner roof unit and an outer roof unit in a self-supporting form as a three-dimensional truss using opposing truss members;
A step of laying the inner roof unit between the walls facing the beam direction, and placing the inner roof unit on the inner track, the inner track and the outer track running in parallel in the beam direction in the upper part and laid in parallel in the beam direction;
Laying the outer roof unit between the opposing walls and placing it on the outer track; and
Each time the inner roof unit is installed between the opposing walls, it is moved in the row direction, and the operation of connecting the adjacent inner roof units to each other is repeated to form an inner roof frame structure movable in the row direction,
Each time the outer roof unit is installed between the opposing walls, the outer roof unit is moved in the row direction, and the operation of connecting the adjacent outer roof units to each other is repeated to form an outer roof structure movable in the row direction. Used to stabilize and stabilize the inner roof unit and the outer roof unit until the inner (outer) roof frame is completed in the process of constructing the inner (outer) roof frame in the construction method of the roof frame including Is done.

  The stop member straddles the inner (outer) track, and is temporarily fixed to the wall (girder) by, for example, a clamp or the like. In the case where temporary fixing with only a clamp is not sufficient, the inner (outer) track is temporarily fixed in a state of being locked to a fastening device fastened to a wall (girder). The inner (outer) roof unit maintains a stationary state by the contact members fixed to both sides of the leg in the running direction being locked to the stop member of the movement preventing device.

  The stop member and the abutting member may be arranged on both sides in the running direction with respect to one inner (outer) roof unit, for example, both sides in the running direction of the pillar members constituting the inner (outer) roof unit, or the inner (outer) roof. Arranged on one side of one column member and on the other side of the other column member located on both sides in the column direction of the unit.

When the inner (outer) roof unit is moved, it is also necessary to ensure the stability of the inner (outer) roof unit against rolling up or falling due to the wheels traveling on the track. Therefore, the lifting prevention device according to claim 4 is installed as a means for ensuring stability during movement of the legs of the inner (outer) roof unit.

This anti-lifting device is opposed to the beam-to-beam direction, and is arranged between the column members that are arranged in parallel in the column direction, the beam members that are installed between the column members that are arranged in parallel in the column direction, and the column members that are opposed in the direction of the beam. Producing an inner roof unit and an outer roof unit in a self-supporting form as a three-dimensional truss using truss members facing in the direction;
A step of laying the inner roof unit between the walls facing the beam direction, and placing the inner roof unit on the inner track, the inner track and the outer track running in parallel in the beam direction in the upper part and laid in parallel in the beam direction;
Laying the outer roof unit between the opposing walls and placing it on the outer track; and
Each time the inner roof unit is installed between the opposing walls, it is moved in the row direction, and the operation of connecting the adjacent inner roof units to each other is repeated to form an inner roof frame structure movable in the row direction,
Each time the outer roof unit is installed between the opposing walls, the outer roof unit is moved in the row direction, and the operation of connecting the adjacent outer roof units to each other is repeated to form an outer roof structure movable in the row direction. In the step of constructing the inner roof frame and the step of configuring the outer roof frame of the construction method of the roof frame including the inner roof unit and the outer roof unit along the inner track and the outer track, respectively. Used for running purposes. The anti-lift device is fixed to both sides of the wall in the width direction of the inner (outer) track, and fixed to the legs of the inner (outer) roof unit, and can be locked to the wall in the width direction of the wall. And a stopper.

  For the above purpose, the slip prevention member is locked to the receiving member when the inner (outer) roof unit is deformed (lifted) exceeding a certain amount, and prevents the inner (outer) roof unit from falling. A clearance greater than the amount of deformation allowed for the inner (outer) roof unit is ensured between the stopper member and the receiving member.

  The stopper is fixed to the legs of the inner (outer) roof unit. When the inner (outer) roof unit swings in the width direction of the track (inter-beam direction), Lock. Since the rocking of the inner (outer) roof unit occurs when it is about to rotate and displace around the contact point (contact surface) between the wheel and the track, the clearance between the stopper and the receiving member is the inner ( Outer side) This refers to the distance between the surfaces where the anti-slip material and the receiving material face each other in the direction in which the roof unit rotates around the track, and this clearance is mainly secured in the vertical direction.

  Each of the inner roof frame and the outer roof frame travels on the inner track and the outer track laid on the wall, so that the inner roof frame and the outer roof frame can travel independently on the track. In addition, the outer roof frame is located on the outdoor side of the inner roof frame so that it can move freely between the outer (inner) roof frame and the inner (outer) roof. It is possible to move to either side in the column direction with respect to the frame. In the completed state of the roof frame, it can be freely opened and closed as long as any inner (outer) roof frame does not collide with each other, and there is a degree of freedom in the arrangement of the inner roof frame and the outer roof frame.

  Specifically, from the state in which both roof frames are in the closed position, the state in which the all inner roof frame or all outer roof frame is close to one side of the wall, and the other side is close to the other side. In between, it is possible to move each inner roof frame and each outer roof frame to a free position.

  For example, when two inner roof frames are placed on the inner track and one outer roof frame is placed on the outer track, the plane of the structure is divided into three regions in the direction of the line. The In this case, the outer roof frame can be located in any of the three regions, and there are three ways of arrangement. For each of the three arrangement positions of the outer roof frame, one of the inner roof frames overlaps with the outer roof frame and the structure is opened from the outer roof frame. A state in which the sky is closed can be selected.

  Since the inner roof frame and the outer roof frame are freely movable, the position of any inner roof frame or outer roof frame can be opened from the closed state in the entire roof frame. As a result, in addition to carrying in / out materials and equipment used in the structure or lifting equipment etc. through the open area, it is also possible to incorporate wind and light into the roof frame. Of the roof frame, the range (section) that is open in the direction of the beam is the inner roof frame unit or the outer roof frame unit.

  The roof frame consists of two types of roof frames inside and outside, and only two tracks are laid in a straight line on the wall, so the inner roof frame and the outer roof frame overlap, Since the roof frame does not overlap at the same time, the plane of the structure is not restricted to a specific shape. Also, since the inner (outer) roof frame is separated from the wall and moves independently of the wall, the wall will not be absent when the roof frame consisting of both roof frames is closed. It can be used as an indoor space.

  The inner roof structure and the outer roof structure are supported by the walls facing each other in the beam-to-beam direction and are independent of the walls, so the roof structure and the wall do not move simultaneously, and are related to the movement of the roof structure. There are always walls on both sides of the beam.

  Therefore, if both sides of the structure in the crossing direction are closed by a gable wall or shutters, intrusion of rainwater into the structure is avoided in the closed state of both the inner and outer roof structures. Since it is protected from wind and rain, the inside of the structure can be put into use even when it rains. In addition, since the wall is fixed to the ground, it is possible to lay various equipment, electrical equipment, etc., as well as indoor piping and wiring including walls and pillars. It is also possible to install temporary rooms such as toilets, break rooms, and management rooms.

  By constructing the inner (outer) roof unit in a self-supporting form as a three-dimensional truss at the time of hanging on the inner (outer) movement, the inner (outer) roof unit is installed between opposing walls, and the inner (outer) ) It can be run from the time it is placed on the track. In addition, since the truss is suspended on the inner (outer) track with the position of the leg of the column member secured in advance, the truss is suspended in advance from the time of suspension. Can be connected to adjacent inner (outer) roof units. As a result, since the work on the track is not stagnated, the work on the track is simplified.

  According to the method of preceding the step of constructing the inner roof unit (constructing the inner roof frame), the inner roof frame that overlaps the indoor side when the outer roof unit is constructed (when the outer roof frame is constructed). Since the work can be performed by using the, a scaffold to be installed indoors can be omitted or simplified. As a result, the time (period) required to assemble and disassemble the indoor scaffold can be greatly shortened, and the construction period can be shortened in addition to the simplification of the work on the track.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  In FIG. 1, an inner track 2 a and an outer track 2 b that are continuous in the beam direction and are arranged in parallel in the beam-to-beam direction are laid. The structural example of the roof frame 3 completed by erection is shown.

  The wall 2 constitutes a part of the structure 1 including the roof frame 3. The inner roof unit 4 and the outer roof unit 5 are connected to a plurality of inner roof units 4 and outer roof units 5 that are adjacent to each other in the row direction, thereby forming an inner roof frame 40 and an outer roof frame 50. The outer roof frame 50 is located outside the structure 1 with respect to the inner roof frame 40.

  The wall 2 is constructed on the ground with a distance in the direction between the beams of the structure 1, and as shown in FIG. 2, the inner track 2a and the outer track 2b on which the inner roof unit 4 and the outer roof unit 5 travel on the top, etc., respectively. Are laid in parallel in the interbeam direction. In the drawings, as shown in FIGS. 2 and 6, the frame of the wall 2 is composed of steel-structured assembly columns 21 arranged at intervals in the row direction, and between the adjacent assembly columns 21 and 21 in the row direction, both However, the wall 2 may be constructed of reinforced concrete or the like regardless of the construction method and the structural type of the wall 2.

  In FIG. 2, the assembly column 21 itself is composed of a plurality of column members 21a, a connecting member 21b for connecting adjacent column members 21a and 21a to each other, and a lattice member 21c. The column member 21a is fixed to the ground by an anchor so as to ensure sufficient stability against a fall due to a load of the inner roof unit 4 and the outer roof unit 5 placed on the wall 2. The details near the top of FIG. 2 are shown in FIG.

  As shown in FIG. 6, the assembly columns 21 arranged in the direction of the spar are connected by a spar 22, a connecting member 23, a brace 24, and the like to form a framework of the wall 2, and as shown in FIGS. 2 and 3, the spar 22 An inner track 2a and an outer track 2b made of rails and the like are laid on the upper layer portion of the assembly column 21, such as the top of each.

  In FIGS. 2 and 3, the rail-type inner track 2 a and the outer track 2 b are laid on the top of the girder 22, and three beams 22 are arranged on the top of the assembly column 21, so An inner track 2a is laid on the girder 22, and an outer track 2b is laid on the girder 22 on the outer side in the interbeam direction. Here, the inner track 2a and the outer track 2b are arranged at the same level, but a step may be provided on both tracks 2a, 2b.

  In the drawing, rails having an I-shaped cross section are used for these tracks 2a and 2b, but the shape of the track is determined by the shape of the wheels 4a and 5a connected to the inner roof unit 4 and the outer roof unit 5, and is formed in a groove shape. May be formed. The wheels 4a and 5a are connected to the lower ends of the column members 41 and 51 constituting the inner roof unit 4 and the outer roof unit 5, respectively.

  3 (a) and 3 (b) show the procedure for adjusting the position of the inner roof unit 4 in the width direction (inter-beam direction) and ensuring stability when the wheels 4a of the inner roof unit 4 are placed on the track 2a. Is shown. The position adjustment of the column member 41 of the inner roof unit 4 placed on the wall 2 is performed by using a wire or other tensile material laid between both sides in the width direction of the column member 41 and the beam 22 of the wall 2 (assembly column 21). 6 etc. The width direction of the column member 41 is a beam-to-beam direction and indicates the width direction of the track 2a.

  In order to keep the inner roof unit 4 stationary on the inner track 2a when adjusting the position of the column member 41 in the width direction, a movement preventing device 10 as shown in FIG. 9 is used together. The movement preventing device 10 is disposed on both sides in the running direction of the leg portion of the inner roof unit 4 (column member 41), and is stopped on the wall 2 (girder 22) while straddling the inner track 2a, As shown to 3- (b), it is comprised from the contact member 12 fixed in the state which can be contact | abutted to the stop member 11 on the both sides of the running direction of the leg part of the inner roof unit 4 (column member 41).

  As shown in FIG. 9, the stop member 11 has a planar stop plate 11a with which the contact member 12 abuts, and a fixed plate 11b constrained in a state where it overlaps the upper surface of the girder 22, and the stop plate 11a has a plate thickness. A rib 11c for preventing deformation in the direction is fixed across the fixing plate 11b. The fixed plate 11b is maintained temporarily fixed to the girder 22 by a clamp 13 or the like that sandwiches the girder 22 at the same time.

  Fastening devices 14 are disposed on both sides of the inner track 2a in the width direction and spaced in the length direction to restrain the inner track 2a to the spar 22 and are fixed to the spar 22 by bolts 15. Is fixed to the fastening device 14 or the bolt 15 at the fixing plate 11b or the rib 11c, so that the stability in the fixed state to the girder 22 is enhanced.

  After the position adjustment of the column member 41, the stability during traveling of the inner roof unit 4 is ensured by the lift prevention device 16 for traveling the inner roof unit 4 along the inner track 2a as shown in FIG. The After the lifting prevention device 16 is fixed, the holding by the tension member 6 is released, and the inner roof unit 4 can run on the inner track 2a.

  As shown in FIG. 10, the anti-lifting device 16 is provided on the wall 2 (girder 22) on the legs 2c of the inner roof unit 4 (column member 41) and the receiving material 2c fixed to the both sides in the width direction of the inner track 2a. The anti-slip material 41a is fixed and can be locked to the receiving material 2c in the width direction of the wall 2. The receiving member 2c fixed to the girder 22 is fixed to the girder 22 from before the inner roof unit 4 is placed on the track 2a.

  The traveling of the inner roof unit 4 on the inner track 2a is performed while maintaining a clearance between the slip prevention member 41a and the receiving member 2c. The receiving member 2c has, for example, a groove-shaped cross-section that is open on the inner track 2a side, and the slip-preventing member 41a is locked to the receiving member 2c from the inner track 2a side to cause the column member 41 to fall over, Prevents lifting and derailment during an earthquake.

  Since the rolling of the inner roof unit 4 occurs when the wheel 4a connected to the leg portion of the column member 41 is about to rotate with respect to the track 2a, the clearance is when the leg portion of the column member 41 is about to rotate. Therefore, the anti-separation material 41a and the receiving material 2c are ensured in the direction in which they approach (oppose) each other.

  Also in FIG. 10, when the inner roof unit 4 tries to be displaced horizontally in the width direction of the track 2a, the anti-slip material 41a is locked between the anti-slip material 41a and the base material 2c so that the anti-slip material 41a is locked to the base material 2c. Has a horizontal clearance.

  FIG. 3C shows a procedure for securing the stability of the outer roof unit 5 when the wheels 5a of the outer roof unit 5 are placed on the outer track 2b. In this case, since the column member 51 is placed at a position close to the width direction side of the assembly column 21, the stability of the column member 51 from both sides in the width direction of the column member 51 as shown in FIG. Since the jack 7 is disposed on one side of the column member 51, the column member 51 is held.

  The stationary state after the outer roof unit 5 is placed on the outer track 2b is maintained by the movement preventing device 10, and the stability during traveling is ensured by the lifting preventing device 16.

  In parallel with the construction of the wall 2 or after the construction of the wall 2, the inner roof unit 4 and the outer roof unit 5 are manufactured (assembled) on the ground. Both the inner roof unit 4 and the outer roof unit 5 are basically opposed to each other in the beam-to-beam direction as shown in FIG. 4, and between the column members 41 and 51 arranged in parallel in the column direction and between the column members 41 and 51 arranged in parallel in the column direction. The beam members 42 and 52 are installed between the beam members 42 and 52, and the column members 41 and 51 which are opposed to each other in the beam-to-beam direction. The truss members 43 and 53 are composed of an upper chord member, a lower chord member, and a diagonal member connecting the two. The beam members 42 and 52 are basically installed between the tops of the column members 41 and 41 (51 and 51), but may also be installed between the legs.

  As shown in FIG. 5, connecting members 44 and 54 for securing rigidity are installed between the truss members 43 and 53 arranged in parallel in the direction of the beam. 4 and 5 show the inner roof unit 4 and the outer roof unit 5 without distinction. Hereinafter, the description of the both roof units 4 and 5 will be represented by the inner roof unit 4. In FIG. 4, 46 (56) indicates a temporary wire for connecting the inner roof units 4 (outer roof units 5) adjacent to each other in the row direction.

  FIG. 6B shows a state in which an inner roof frame 40 is constituted by a plurality of inner roof units 4 and the wall 2 is moved in the column direction in that state. In FIG. 6, the inner roof frame 40 includes three or four inner roof units 4, a connecting member 44 that connects adjacent inner roof units 4, 4, and braces 45.

  In FIG. 6- (b), it seems that the inner roof frame 40 is composed of eight inner roof units 4 positioned on the arrow side, but is connected between the adjacent inner roof units 4 and 4. When the material 44 and the brace 45 are erected, the inner roof frame 40 is constituted by the four inner roof units 4. In FIG. 6B, the two inner roof units 4, 4 near the crane 8 constitute the next inner roof frame 40. The outer roof frame 50 is configured in the same manner as the inner roof frame 40.

  The ends of the inner roof units 4, 4 located on both sides of the inner roof frame 40 in the row direction protrude to the adjacent outer roof frame 50 side so as to overlap the adjacent outer roof frame 50 when the roof frame 3 is closed. To do.

  FIGS. 7A to 7H show the inner roof frame 40 and the outer roof frame 50 when the roof frame 3 is composed of three inner roof frames 40 and two outer roof frames 50. FIG. The procedure of hanging on the wall 2 is shown. FIG. 7- (i) shows the plane of the roof frame 3 when the installation of the entire inner roof frame 40 and the outer roof frame 50 is completed. 8A shows a plane showing only the outer roof frame 50 laid between the opposing walls 2 and 2, and FIG. 8B shows a plane showing only the inner roof frame 40. (C) is a side view.

  In FIG. 7, reference numerals 1, 3, and 5 indicate the inner roof frame 40, and 2 and 4 indicate the outer roof frame 50. Here, the assembly of the three inner roof frames 40 is the assembly of the outer roof frame 50. The outer roof frame 50 is constructed after the inner roof frame 40 is completed.

  By assembling the inner roof frame 40 in this way, the column member 41, the beam member 42, and the like of the inner roof frame 40 positioned on the indoor side can be used as a scaffold when the outer roof frame 50 is constructed. The scaffold for assembling the outer roof frame 50 does not need to be assembled on the indoor side or can be omitted. Therefore, as the scaffolding for the outer roof frame 50, it is only necessary to assemble the outdoor scaffolding (external scaffolding in FIG. 7- (a)). Regardless of the number of outer roof frames 50, a scaffold for this outer roof frame 50 is sufficient if there is a section (length) of one outer roof frame 50 in the direction of the beam.

  Further, depending on the finishing of the outer walls of the inner roof frame 40 and the outer roof frame 50, as the scaffold for the inner roof frame 40, the external scaffold shown in FIG. 7- (a) is replaced with one inner roof unit 4 (outer roof unit 5). ) May be assembled as much as possible.

  In FIG. 8, the inner roof frame 40 located in the middle part of the crossing direction is apparently composed of seven inner roof units 4, and the other inner roof frame 40 and the outer roof frame 50 are each eight inner frames. The case where it comprises the roof unit 4 and the outer roof unit 5 is shown.

  As shown in FIG. 7- (i), the outer roof frame 50 overlaps the inner roof frame 40, and the inner roof frame 40 is located below the outer roof frame 50. Therefore, in principle, after the three inner roof frames 40 are installed between the walls 2 and 2 in advance, the two outer roof frames 50 are installed. However, in this example, the number of the outer roof frames 50 is smaller than the number of the inner roof frames 40, and the outer roof frames 50 can be moved to one side of the wall 2 in the row direction. May be erected in advance.
