Description

  The present invention relates to an installation structure for installing a door such as a radiation shielding door on a building frame.

  Conventionally, radiation shielding doors are used in buildings that handle radioactive materials such as nuclear power plants. As an example, Patent Document 1 discloses a sliding door.

  On the other hand, there is a type of shielding door that is opened and closed by turning inside the frame with a hinge provided on a frame such as a four-sided frame as a fulcrum. And in the case of this hinge type, the said frame is fixed to the opening part of the wall part of a building frame, and a shielding door is installed in a building frame.

  Such a hinge-type shielding door is usually manufactured in a factory as an integral structure with the frame, and shipped at the same time as the frame. This is because, from the viewpoint of radiation shielding, it is important to manage the gap between the frame and the shielding door, and in order to ensure the conditions, it is necessary to manufacture the frame and the shielding door at the same time.

  However, in such simultaneous shipment, the shipment of both the frame and the shield door is awaited, and the production period is inevitably long (usually about 3 to 5 months), and the order of materials must be advanced. Incurs longer construction period.

  In addition, the shield doors are generally large, and due to transportation restrictions, the doors and frames assembled at the factory are once disassembled and brought into the field and reassembled. Contributes to longer construction costs and increased construction costs.

  Furthermore, when the wall part of the building frame is made of concrete, it is necessary that the installation (installation) of the frame to the foundation of the building frame is completed before the bar arrangement work. In such simultaneous shipment, the construction start time of the wall portion is delayed due to being pulled by the delivery date of the frame, and as a result, the construction progress of the building frame is delayed.

  In addition, depending on the installation conditions and the like, the installation state of the door and the frame when the frame is installed on the wall portion of the building frame may change from the state when temporarily assembled at the factory. In other words, even if there is no problem at the time of temporary assembly, there is a risk that the door and the frame may interfere with each other after the installation to the building frame, and the door and the frame may interfere with each other. Cost.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an installation structure for a door of a building that can shorten the work period and reduce the cost.

FIG. 4 is a longitudinal sectional view taken along arrow IV-IV in FIG. 1A.

  As shown in FIGS. 1A and 1B, the radiation shielding door 21 is used in a building 1 that contains a radioactive substance such as a nuclear facility. The frame of the building 1 is made of concrete such as RC to shield radiation, and a substantially rectangular opening 7 (hereinafter referred to as “entrance”) is provided in the frame wall 5 standing upright from the frame floor 3. , Also referred to as a housing opening 7). The housing opening 7 is provided with the shielding door 21 via a four-sided frame 31 fixed to the inner peripheral surface 7a.

  In the following description, directions are defined based on a state in which the shielding door 21 is viewed from the outside of the building 1. For example, the outside of the building 1 is called the near side in the prospective direction, and the inside of the building 1 is called the back side in the prospective direction. The direction of finding is also referred to as the left-right direction.

  As shown in FIG. 1A and FIG. 1B, the shielding door 21 has a bottomed box member 23 made of steel, in which concrete is densely filled after a reinforcing material (not shown) such as a reinforcing bar is disposed inside. And it is supported by the hinge 33 of said four-way frame 31, for example, opens and closes by making the left side of the shielding door 21 into the door-end side.

  The appearance of the shielding door 21 is a substantially rectangular parallelepiped having a rectangular shape in front view and having a predetermined wall thickness in the prospective direction. And three side surface 21R, 21U, 21D except the door-end side among the four side surface 21R, 21L, 21U, 21D is formed in the surface substantially parallel to a prospective direction, as shown in FIG.2 and FIG.4. However, the side 21L on the door-end side shown in FIG. 3 is formed as an inclined surface inclined obliquely from the prospective direction. The four side surfaces 21R, 21L, 21U, and 21D are each formed with a stepped portion ST1 at a substantially intermediate position in the prospective direction. That is, the side surfaces 21R, 21L, 21U, The back side portion is retracted stepwise inwardly than the near side portion in the prospective direction in 21D. Correspondingly, the inner peripheral surface 31a of the four-sided frame 31 also has a stepped portion ST2, and the stepped portion ST2 is used as a boundary, and the inner portion of the inner peripheral surface 31a is closer to the farther side in the prospective direction. This protrudes stepwise inwardly of the side, whereby a substantially crank-shaped gap G is provided between the shielding door 21 and the four-sided frame 31. And, according to the substantially crank-shaped gap G, the linear passage of radiation is prevented, thereby ensuring the desired gap G between the shielding door 21 and the four-sided frame 31, while the gap G To prevent leakage of radiation.

  As shown in FIG. 1A and FIG. 1B, the four-sided frame 31 is a rectangular frame made of, for example, steel. Specifically, the vertical frame portions 40 and 50 respectively disposed on the left and right sides in the finding direction and the vertical frame portions 40 , 50 and an upper frame portion 60 spanned over the upper end portions of the vertical frame portions 40, 50, and a lower frame portion 70 spanned over the lower end portions of the vertical frame portions 40, 50. Further, hinges 33 are respectively provided at both ends in the vertical direction of the right vertical frame portion 40, and the shielding door 21 is supported to be opened and closed by using the pair of upper and lower hinges 33, 33 as a fulcrum C33. ing. Hereinafter, the right vertical frame portion 40, the left vertical frame portion 50, the upper frame portion 60, and the lower frame portion 70 will be described.

(1) Right vertical frame portion 40
As shown in FIG. 2, the right vertical frame portion 40, that is, the vertical frame portion 40 having the hinge 33 is formed by joining the first plate member 41 and the second plate member 43 at right angles via an angle member 42 or the like. The main body is a member having a substantially L-shaped horizontal cross section. The first plate member 41 is disposed in close contact with the inner peripheral surface 7 a of the housing opening 7, and the second plate member 43 is disposed in close contact with the outer wall 5 a of the housing wall 5. Here, both of the first plate member 41 and the second plate member 43 are provided with stud dowels 49, and these stud dowels 49 are embedded in the housing wall portion 5. Further, the second plate member 43 is also connected and supported via an appropriate connection structure to an H-shaped steel 45 as a support member 45 embedded vertically in the housing wall 5, and this support member The lower end portion of 45 is integrally fixed to a reinforcing material (not shown) such as a reinforcing bar embedded in the frame floor portion 3. Therefore, the said vertical frame part 40 will be firmly integrated with the frame wall part 5 and the frame floor part 3, and this will ensure sufficient intensity | strength to support the said shielding door 21 of a heavy article. Has been.

  As an example of the connection structure, as shown in FIG. 2, connection plates 45p and 45p are fixed to a pair of flanges 45f and 45f of H-shaped steel as a support member 45, which are bridged and fixed via an angle member A1. And the structure etc. which overlap | superposed both the connection plates 43p and 43p integrally extended from the 2nd plate member 43 toward the inward of the housing wall part 5, and fastened with the volt | bolt B are mentioned.

  Further, as described above, the gap G having a substantially crank shape in the horizontal cross section needs to be formed between the right side surface 21R which is the hinge side surface of the shielding door 21 and the vertical frame portion 40. Therefore, the 1st plate member 41 which should oppose the said right side surface 21R of the shielding door 21 has the shape from which the protrusion amount to the finding direction differs in the near side part and the back | inner side part of a prospective direction. . And in order to achieve this shape, the near side part and the back side part are comprised by the mutually different member. That is, the front side portion is the plate body 41a, but the back side portion is a U-shaped member 41b having a horizontal cross-sectional shape that protrudes inward in the direction of finding by the amount of the U-shape. The stepped portion ST2 is provided between the plate body 41a as a part. The U-shaped member 41b is fixed by fixing both end portions in the prospective direction to the plate body 41a and the inner peripheral surface 7a of the housing opening 7 via the angle member A2 or the like, respectively. . Further, in this fixed state, the U-shaped member 41b is surrounded by the inner peripheral surface 7a of the housing opening 7 (see the gray region in FIG. 2) as a cement-type grout material. The mortar M41 is filled densely, thereby effectively shielding the radiation.

(2) Left vertical frame portion 50
As shown in FIG. 3, the vertical frame portion 50 on the left side, that is, the vertical frame portion 50 facing the door-end side surface 21L of the shielding door 21, has a horizontal sectional shape corresponding to the inclined shape of the door-end side surface 21L. The main body is a hollow member 50 which is formed in a substantially triangular shape and whose cross-sectional shape is maintained in the vertical direction. That is, the hollow member 50 has a substantially triangular shape that gradually protrudes in the direction of finding from the near side in the prospective direction toward the far side. Further, the side of the hollow member 50 that faces the door end side surface 21L of the shielding door 21 is closed by the plate member 51, but the side of the housing opening 7 that faces the inner peripheral surface 7a is closed by the plate member. Thus, the hollow space SP50 (see the gray region in FIG. 3) in the hollow member 50 faces the inner peripheral surface 7a of the housing opening 7. And in the state which attached the hollow member 50 to the inner peripheral surface 7a of the housing opening 7, the hollow space SP50 of the hollow member 50 is partitioned into a substantially closed space by the inner peripheral surface 7a. Is densely filled with mortar M50 (see the gray area in FIG. 3) as a cement grout material to shield radiation.

  Similarly to the right vertical frame portion 40 described above, the left vertical frame portion 50 is also substantially crank-shaped when viewed from the horizontal cross section between the left side surface 21L which is the door side surface of the shielding door 21 facing the left vertical frame portion 50. The gap G needs to be formed. Therefore, the hollow member 50 has a stepped portion ST2 at a substantially intermediate position in the prospective direction, and the stepped portion ST2 serves as a boundary, and the inner portion in the rearward direction portion is located in a stepped manner rather than the front side portion in the prospective direction. It protrudes toward.

  Such a hollow member 50 is, for example, welded and fixed to the frame member 53 from the right side of the frame member 53 by assembling a plurality of angle members 53a, 53b and the like in a ladder shape extending in the vertical direction. From the plate member 51 that defines the hollow space SP50 inside the framework member 53, and support brackets BR1, BR2, BR3 for fixing and supporting the framework member 53 to the inner peripheral surface 7a of the housing opening 7. Mainly composed.

  The frame member 53 is formed by welding and fixing a plurality of horizontal members 53b at appropriate intervals in the vertical direction with respect to a plurality of vertical members 53a extending in the vertical direction.

  On the other hand, the plate member 51 is divided into a plate 51a that covers the near side in the prospective direction and a plate 51b that covers the back side, with the stepped portion ST2 as a boundary. Although this will be described in detail later, when the hollow member 50 is fixed to the inner peripheral surface 7a of the housing opening 7 while adjusting the position of the hollow member 50 with respect to the shielding door 21, the position adjustment work is facilitated. This is because it is necessary to remove the back plate 51b from the frame member 53 from the above viewpoint.

  The support brackets BR1, BR2, BR3 are fixed to the inner peripheral surface 7a of the housing opening 7 via an anchor member ANC such as a stud bolt or a chemical anchor. The hollow member 50 is supported by the housing opening 7 by fixing the horizontal member 53b or the vertical member 53a of the frame member 53 to the support brackets BR1, BR2, BR3 with an appropriate fixing structure. In the illustrated example, the support brackets BR1, BR2, and BR3 are respectively arranged at three positions with respect to the prospective direction, that is, the positions of both end portions in the same direction and the position of the stepped portion ST2 that is a substantially intermediate position between these positions. ing. Of the three places related to the prospective direction, an angle member extending in the vertical direction is used for the support bracket BR1 at the front end portion in the prospective direction, and the frame member 53 is used as the angle member BR1. The vertical members 53a at the front side end of each other are overlapped and fixed by welding. On the other hand, the remaining two support brackets BR2 and BR3 in the prospective direction (that is, the support bracket BR2 at the position of the stepped portion ST2 and the support bracket BR3 at the far end in the prospective direction) The support brackets BR2 and BR3 are discretely arranged at a plurality of positions in the direction, and a horizontal member 53b in the vicinity thereof is bolted or the like (bolts are not shown in FIG. 3).

  Here, the latter bolting structure has a position adjusting mechanism so that the position of the hollow member 50 with respect to the shielding door 21 can be easily adjusted. That is, one of the bolt holes H of the support brackets BR2 and BR3 and the bolt hole H of the horizontal member 53b is formed as a long hole that is long in the prospective direction, and the other is formed as a long hole that is long in the direction of finding. Yes. Therefore, by adjusting the bolt positions in these long holes, the position of the hollow member 50 relative to the shielding door 21 can be easily adjusted with respect to the prospect direction and the finding direction. However, the position adjustment method is not limited to the shape of the above-described bolt hole H. For example, the hollow member 50 is displaced by shifting the hollow member 50 in the expected direction and the finding direction for each installation position of the support brackets BR1, BR2, BR3. You may adjust the position of a prospective direction and a finding direction with respect to 50 shielding doors 21.

(3) Upper frame portion 60
As shown in FIG. 4, the upper frame portion 60 is fixed to the inner peripheral surface 7a of the housing opening 7 while facing the upper side surface 21U of the shielding door 21, and as described above, the upper frame portion 60 and the upper side surface 21U of the shielding door 21 A gap G having a substantially crank shape as viewed in a vertical section is formed therebetween. For this reason, the upper frame portion 60 has a hollow member 60 in which the vertical cross-sectional shape is formed in a substantially staircase shape and the cross-sectional shape is maintained over the entire length in the direction of finding (direction passing through the paper surface of FIG. 4). And Specifically, the hollow member 60 has a stepped portion ST2 at a substantially intermediate position in the prospective direction. The stepped portion ST2 serves as a boundary, and the back side portion is stepped downward from the near side portion in the prospective direction. It protrudes. In addition, the side of the hollow member 60 that faces the upper side surface 21U of the shielding door 21 is blocked by the plate member 61, but the side of the housing opening 7 that faces the inner peripheral surface 7a is blocked by the plate member. Thus, the hollow space SP60 (see the gray area in FIG. 4) in the hollow member 60 faces the inner peripheral surface 7a of the housing opening 7. And in the state which attached the hollow member 60 to the inner peripheral surface 7a of the housing opening 7, the hollow space SP60 of the hollow member 60 is partitioned into a substantially closed space by the inner peripheral surface 7a. Is densely filled with mortar M60 (see the gray area in FIG. 4) as a cement grout material to shield radiation.

  Such a hollow member 60 is, for example, welded and fixed to the frame member 63 from below the frame member 63 and a frame member 63 formed in a ladder shape extending in the direction of finding a plurality of angle members 63a, 63b and the like. The plate member 61 that defines the hollow space SP60 inside the frame member 63, and support brackets BR4, BR5, BR6 for fixing and supporting the frame member 63 to the inner peripheral surface 7a of the housing opening 7 Mainly composed.

  The plate member 61 is divided into a plate 61a that covers the near side in the prospective direction with the stepped portion ST2 as a boundary, and a plate 61b that covers the back side, and is fixed to the frame member 63 by welding or the like. The The reason for this division is the same as in the case of the left vertical frame portion 50 described above. That is, when the hollow member 60 is fixed to the inner peripheral surface 7a of the housing opening 7, the position of the hollow member 60 with respect to the shielding door 21 is also adjusted. In this case, the position adjustment work is facilitated. This is because it is necessary to remove the back plate 61b from the frame member 63 in order to achieve this. Details will be described later.

  The support brackets BR4, BR5, BR6 are fixed to the inner peripheral surface 7a of the housing opening 7 via an anchor member ANC such as a stud bolt or a chemical anchor. The hollow member 60 is fixedly supported by the housing opening 7 by fixing the vertical member 63a of the frame member 63 and the like to the support brackets BR4, BR5, BR6 with an appropriate fixing structure. In the illustrated example, the support brackets BR4, BR5, and BR6 are respectively arranged at three positions with respect to the prospective direction, that is, the positions of both end portions in the same direction and the position of the stepped portion ST2 that is a substantially intermediate position between these positions. ing. Of these three locations related to the prospective direction, an angle member extending in the direction of finding is used for the support bracket BR4 at the front end in the prospective direction. The hollow member 60 is used as the angle member BR4. The bent portion 61ap of the near side edge of the near side plate 61a is fixed by welding. On the other hand, the remaining two support brackets BR5 and BR6 in the prospective direction (that is, the support bracket BR5 at the position of the stepped portion ST2 and the support bracket BR6 at the far end in the prospective direction) are found respectively. The support brackets BR5 and BR6 are discretely arranged at a plurality of positions in the direction, and vertical members 63a in the vicinity thereof are bolted or the like (bolts are not shown in FIG. 4).

  Here, for the latter bolting structure, a position adjustment mechanism similar to that of the left vertical frame portion 50 described above is applied, that is, the bolt holes H of the support brackets BR5 and BR6 and the bolts of the vertical member 63a. Either one of the holes H is formed as a long hole that is long in the prospective direction, and the other is formed as a long hole that is long in the vertical direction. However, the position adjustment method is not limited to the shape of the above-described bolt hole H. For example, the hollow member 60 is displaced by shifting the hollow member 60 in the expected direction and the vertical direction for each installation position of the support brackets BR4, BR5, BR6. You may adjust the prospective direction with respect to 60 shielding doors 21, and the position of an up-down direction.

(4) Lower frame portion 70
As shown in FIG. 4, the lower frame portion 70 is fixed to the inner peripheral surface 7 a of the housing opening 7 while facing the lower side surface 21 </ b> D of the shielding door 21, and as described above, the lower side surface of the shielding door 21. A gap G having a substantially crank shape in a vertical sectional view is formed between 21D and 21D. For this reason, the lower frame portion 70 has a hollow member 70 in which the vertical cross-sectional shape is formed in a substantially staircase shape and the cross-sectional shape is maintained over the entire length in the direction of finding (the direction passing through the paper surface of FIG. 4). And Specifically, the hollow member 70 has a stepped portion ST2 at a substantially intermediate position in the prospective direction, and with the stepped portion ST2 as a boundary, the back side portion protrudes upward in a stepped manner from the near side portion in the prospective direction. ing. Further, in the hollow member 70, the side facing the lower side surface 21 </ b> D of the shielding door 21 is blocked by the plate member 71, but the side facing the inner peripheral surface 7 a of the housing opening 7 is blocked by the plate member. Thus, the hollow space SP70 (see the gray region in FIG. 4) in the hollow member 70 faces the inner peripheral surface 7a of the housing opening 7. And in the state which attached the hollow member 70 to the inner peripheral surface 7a of the housing opening 7, the hollow space SP70 of the hollow member 70 is partitioned into a substantially closed space by the inner peripheral surface 7a. Is densely filled with mortar M70 (see the gray area in FIG. 4) as a cement-based grout material to shield radiation.

  Such a hollow member 70 is, for example, a frame member 73 formed by assembling a plurality of angle members 73 a, 73 b and the like in a ladder shape extending in the left and right direction, and the frame member 73 from above the frame member 73 by welding and fixing. The above-described plate member 71 that is equally divided to define the hollow space SP70 inside the framework member 73, and support brackets BR7, BR8, BR9 for fixing and supporting the framework member 73 on the inner peripheral surface 7a of the housing opening 7. And mainly consists of.

  The skeleton member 73 has a plurality of horizontal members 73b extending in the prospective direction at appropriate intervals in the finding direction with respect to the plurality of horizontal members 73a extending along the finding direction (direction passing through the paper surface in FIG. 4). It is formed by welding and fixing.

  The plate member 71 is divided into a plate 71a covering the front side in the prospective direction and a plate 71b covering the back side, with the stepped portion ST2 as a boundary, and is fixed to the frame member 73 by welding or the like. The The reason for this division is the same as in the case of the upper frame portion 60 described above, and will be described later in detail.

  The support brackets BR7, BR8, BR9 are fixed to the inner peripheral surface 7a of the housing opening 7 via an anchor member ANC such as a stud bolt or a chemical anchor. The horizontal member 73a of the frame member 73 is fixed by welding to the support brackets BR7, BR8, BR9, and the hollow member 70 is fixedly supported by the housing opening 7. In the illustrated example, the support brackets BR7, BR8, and BR9 are arranged at three positions, each position at both ends in the same direction, and the position of the stepped portion ST2 that is a substantially intermediate position between these positions with respect to the prospective direction. Each support bracket BR7, BR8, BR9 is arranged to extend over the entire length in the direction of finding. The horizontal members 73a in the vicinity thereof are fixed to the support brackets BR7, BR8, BR9 by welding. Therefore, in the case of this illustrated example, the position adjustment in the expected direction and the vertical direction of the hollow member 70 with respect to the shielding door 21 is performed with respect to the installation position of the support brackets BR7, BR8, BR9 in the expected direction and the support brackets BR7, BR8, BR9. This is done by adjusting the vertical overlapping margin of the frame member 73 or the like. However, the position adjustment mechanism may be provided as in the left vertical frame portion 50 and the upper frame portion 60 described above, thereby adjusting the position.

<<< How to install radiation shielding door 21 >>>
5A to 5E are explanatory views of the installation method of the radiation shielding door 21, and any of the drawings is shown in a front view.

  Hereinafter, the state illustrated in FIG. 5A will be described as an initial state. That is, as an initial state, it is assumed that the building floor 3 as the foundation of the building 1 is almost completed, but the building wall 5 is not yet formed. In addition, it is assumed that the support member 45 made of H-shaped steel has been erected on the upper surface of the frame floor 3 integrally with the frame floor 3.

  First, in parallel with the work related to the initial state, the second plate member 43 related to the right vertical frame portion 40 is manufactured at the factory and is carried on site. In addition, the hinge 33 has already been installed in the 2nd plate member 43 at the time of this carrying in.

  Next, as shown in FIG. 5B, the second plate member 43 in which stud studs 49 have been previously planted is fixed to the support member 45 erected from the frame floor 3. That is, as shown in FIG. 2, the connecting plate 45 p provided in the support member 45 and the connecting plate 43 p provided in the second plate member 43 are overlapped with each other and fastened and fixed by the bolt B. If it does so, the 1st plate member 41 will be connected to the 2nd plate member 43 at right angles via the angle material 42, and, thereby, the main part of the right side vertical frame part 40 will be in the state installed in the foundation 3 of a building. Become. That is, this process corresponds to the “first process” according to the claims.

  By the way, the “main part of the right vertical frame portion 40” is referred to here as the first plate member 41 at this time has only the plate body 41a which is the front side portion in the prospective direction, This is because the U-shaped member 41b which is the side portion is not yet provided. The U-shaped member 41b is attached after the shielding door 21 is attached to the hinge 33, as will be described later.

  Next, as shown in FIG. 5C, the housing wall 5 having the housing opening 7 is constructed of concrete (corresponding to the “wall forming process” according to the claims). That is, it should be constructed by disposing a formwork (not shown) at the positions to be the outer wall surface 5a and the inner wall surface 5b of the housing wall portion 5 to be constructed, and at the position to be the inner peripheral surface 7a of the housing opening portion 7. A space having the shape of the frame wall portion 5 is defined, and a reinforcing material (not shown) such as a reinforcing bar is disposed in the same space in parallel or in parallel with the space. Then, concrete is placed in the same space, and the formwork is removed after the concrete is hardened, thereby building the frame wall 5 having the frame opening 7 as shown in FIG. 5C. Incidentally, the support member 45 is located in the space where the concrete is placed, and the right vertical frame portion 40 functions as a part of the mold, and thereby, the support members 45. And the vertical frame part 40 of the right side is integrated with the frame wall part 5 (refer FIG. 2).

  Next, as shown in FIG. 5D, the shielding door 21 is attached to and supported by the hinge 33 of the right vertical frame portion 40 (corresponding to “second step” according to the claims). That is, the shield door 21 made of steel made in the factory in parallel with the above-described site construction (attachment of the second plate member 43 to the support member 45, construction of the frame wall portion 5) as shown in FIGS. 5B and 5C. The uncovered bottomed box member 23 is carried in the field, and the box member 23 is suspended on the hinge 33 of the right vertical frame portion 40, and the box member 23 is attached to and supported by the hinge 33. At this time, since the concrete is not yet filled in the box member 23, its weight is relatively light and can be suspended easily. Then, a reinforcing material (not shown) such as a reinforcing bar is disposed in the box member 23, and after placing and filling the concrete in the box member 23, the upper surface of the box member 23 is covered with a lid member (not shown). Thus, the attachment of the shielding door 21 to the vertical frame portion 40 is completed.

  Next, as shown in FIG. 5E, the remaining frame portions in the four-sided frame 31 (a U-shaped member 41b in the right vertical frame portion 40, the left vertical frame portion 50, the upper frame portion 60, and the lower frame portion 70). Is attached to the inner peripheral surface 7a of the housing opening 7 while using the shielding door 21 as an attachment position reference (corresponding to "third step" according to the claims).

  The remaining frame portions 41b, 50, 60, and 70 are also manufactured at the above-described factory. However, the manufacturing can be performed after the above-described right vertical frame portion 40 is brought into the field. That is, the construction work on the right side of the vertical frame portion 40 and the shielding door 21 as shown in FIGS. 5B to 5D described above (attachment of the second plate member 43 to the support member 45, construction of the frame wall portion 5, construction of the shielding door 21). The remaining frame portions (the U-shaped member 41b, the left vertical frame portion 50, the upper frame portion 60, and the lower frame portion 70) are manufactured in parallel with the attachment to the right vertical frame portion 40). be able to. Therefore, the construction period can be shortened.

  The order of attaching the remaining frame portions 41b, 50, 60, and 70 is basically random, and the order of attachment described below is merely an example, and is not limited to this order of attachment.

  First, as shown in FIG. 2, a U-shaped member 41 b that is the remaining part of the right vertical frame portion 40 is attached to the inner peripheral surface 7 a of the housing opening 7. In that case, the U-shaped part is actually closed so that the gap G between the closed side of the shielding door 21 and the right side surface 21R of the closed state falls within the intended management tolerance. The member 41b is fixed while adjusting the position in the finding direction and the prospective direction. The reason why the gap G has a management tolerance not only in the direction of finding but also in the prospective direction is that the shape of the gap G is substantially a crank shape as described above. Further, the fixing to the inner peripheral surface 7a is performed by using the angle material A2 described above. After fixing the U-shaped member 41b, the grout material M41 (see the gray area in FIG. 2) is densely placed in a substantially closed space where the U-shaped member 41b is partitioned by the inner peripheral surface 7a. In fact, the U-shaped member 41b is integrated with the housing wall 5 by filling.

  Next, as shown in FIG. 3, the left vertical frame portion 50 is attached to the inner peripheral surface 7 a of the housing opening 7. In that case, as described above, the vertical frame is set so that the shielding door 21 is closed and the gap G between the closed side door 21 and the left side surface 21L falls within the desired management tolerance. The position of the hollow member 50 as the portion 50 is adjusted in the direction of finding and the direction of prospect. Here, this position adjustment is performed, for example, by the above-described position adjustment mechanism, that is, the bolting structure of the support brackets BR2 and BR3 on the inner peripheral surface 7a side and the horizontal member 53b on the frame member 53 side. However, since this bolting structure is located in the back side part in the hollow space SP50 of the hollow member 50, if the back side part of the hollow member 50 is covered with the plate 51b, the bolting structure is operated. It becomes difficult to reach. Therefore, at the time of this position adjustment, only the plate 51 a that covers the front side portion of the hollow member 50 is attached to the frame member 53, and the plate 51 b that covers the back side portion is removed from the frame member 53. And after this position adjustment, in order to fix this positional relationship, the support brackets BR2 and BR3 and the horizontal member 53b of the frame member 53 are welded and fixed, and the support bracket BR1 and the vertical member 53a of the frame member 53 are fixed by welding. To do. Then, the plate 51b related to the back side portion is welded and fixed to the frame member 53 and covered, and then the grout material M50 (in FIG. 3) is formed in a substantially closed space where the hollow member 50 is partitioned by the inner peripheral surface 7a. The left vertical frame portion 50 as the hollow member 50 is integrated with the housing wall portion 5.

  Next, as shown in FIG. 4, the upper frame portion 60 is attached to the inner peripheral surface 7 a of the housing opening 7. In that case, similarly to the above, the upper door is closed so that the gap G between the closed door 21 and the upper side surface 21U of the closed door 21 is within an intended management tolerance. The position of the hollow member 60 as the portion 60 is adjusted in the vertical direction and the prospective direction. Here, this position adjustment is performed by, for example, the above-described position adjustment mechanism, that is, a bolting structure of the support brackets BR5 and BR6 on the inner peripheral surface 7a side and the vertical member 63a on the frame member 63 side. However, since this bolting structure is also located in the back side part in the hollow space SP60 of the hollow member 60, if the back side part of the hollow member 60 is covered with the plate 61b, the bolting structure is operated. It becomes difficult to reach. Therefore, at the time of this position adjustment, only the plate 61 a that covers the near side portion of the hollow member 60 is attached to the frame member 63, and the plate 61 b that covers the back side portion is removed from the frame member 63. And after this position adjustment, in order to fix this positional relationship, the support brackets BR5, BR6 and the vertical member 63a of the frame member 63 are fixed by welding, and the support bracket BR4 and the bent portion 61ap of the plate 61a are connected. Fix by welding. Then, the plate 61b related to the back side portion is welded and fixed to the frame member 63 and covered, and then the grout material M60 (in FIG. 4) is formed in a substantially closed space where the hollow member 60 is partitioned by the inner peripheral surface 7a. The upper frame portion 60 as the hollow member 60 is integrated with the housing wall portion 5.

  Finally, as shown in FIG. 4, the lower frame portion 70 is attached to the inner peripheral surface 7 a of the housing opening 7. In that case, as described above, the shielding door 21 is closed, and the clearance G between the closed shielding door 21 and the lower side surface 21D of the closing door 21 falls within the desired management tolerance. The position of the hollow member 60 as the frame portion 70 is adjusted in the vertical direction and the prospective direction. Here, this position adjustment is performed, for example, by adjusting the installation position of the support brackets BR7, BR8, BR9 and the vertical overlap of the frame member 73 with respect to the support brackets BR7, BR8, BR9. However, since at least the support bracket BR8 positioned at the stepped portion ST2 is positioned in the hollow space SP70 of the hollow member 70, the support portion BR8 is covered with the plate 71b. It becomes difficult for the operator to reach the bracket BR8. Therefore, at the time of this position adjustment, the plate 71 b that covers the back side portion of the hollow member 70 is removed from the frame member 73. Then, after this position adjustment work or welding work to fix the positional relationship after the position adjustment, the plate 71b related to the back side portion is welded and fixed to the frame member 73, and then the lid is closed. A substantially closed space partitioned by the inner peripheral surface 7a is densely filled with a grout material M70 (see a gray region in FIG. 4), whereby the lower frame portion 70 as the hollow member 70 is integrated with the housing wall portion 5. It becomes.

  By the way, the attachment work of these remaining frame parts (the U-shaped member 41b, the left vertical frame part 50, the upper frame part 60, the lower frame part 70) to the housing opening 7 is filled with concrete. The completed shielding door 21 is used as an attachment position reference. Therefore, the remaining frame portions 41b, 50, 60, and 70 can be installed in consideration of distortion and bending due to the dead weight of the shielding door 21, so that the shielding door 21 and the remaining frame portions 41b, 50, 60, and The gap G with respect to 70 can be surely kept within the desired management tolerance, and as a result, the time required for reworking and the cost thereof can be reduced.
