A vertical outer bone 102 is erected at the joint of 01 m, and thereafter,
A first-stage outer panel 103 having a height of about 600 mm and a width of about 900 mm covering the outer bone 102 is placed on the lower frame 101 and fixed to the inner surface of the outer bone 102, and then the separator 104 is placed on the inner surface of the outer panel 103. Attach.

[0005] Thereafter, a waterproof seal 105 is placed on the upper surface of the inner peripheral portion of the lower frame 101, and a first-stage inner panel 106 having a height of about 600 mm and a width of about 900 mm is placed on the waterproof seal 105, and a separator 104 is placed. The outer panel 103 and the inner panel 106 are connected at regular intervals through
Adjacent inner panels 106 are joined by inner bone 107.

In this manner, the lowermost outer panel 103
And after assembling the inner panel 106 to the lower frame 101, the wall reinforcing bar 10 having a diameter of, for example, 10 mm is provided between the panels 103 and 106.
8 are set in the vertical direction and the width direction at intervals of 100 mm, and the abdominal fold 109 serving also as a scaffold is attached to the inner bone 107. Then, as shown in the sectional view of FIG.
The concrete 110 is poured in between 06 and cured for about 3 days to form the lower part of the caisson.

[0007] Thereafter, as shown in the cross-sectional view of FIG. 23, the second outer panel 103 from the bottom is attached to the outer bone 102, and the inner panel 106 from the second lower is attached to the separator 104.

[0011]

According to this conventional basement submersion method, a caisson wall frame composed of a lower frame and a wall frame is formed into a first-stage portion and other portions,
In the meantime, the submarine caisson construction work is carried out under the caisson, and the concrete work is divided into the concrete work under the caisson and the concrete work at the top of the caisson. There is.

Further, since the concrete 110 is joined after the fourth-stage panels 103 and 106 are assembled, it is difficult to clean the joint surface between the concrete below the caisson and the concrete above the caisson. Foreign matter enters the surface and cracks easily occur, and groundwater may enter the basement from the cracks.

Further, since it is necessary to assemble the outer bone 102 to the lower frame 101 in order to assemble the outer panel 103 to the lower frame 101, the process time becomes longer, and the inner and outer panels 103,
Since the number of sheets 106 is large, it takes a long time to assemble them, and furthermore, the third and fourth panels 103,

Things.

[0018]

According to the present invention, there is provided a method for assembling a lower frame on a site of a leveled basement, and a wall frame for completing a wall frame on the lower frame. After making a caisson that conforms to the shape of the basement by performing the construction, the technical feature is that digging the earth and sand inside the lower frame and submerging the caisson consisting of the lower frame and the wall frame into the basement Adopt means.

According to the method of the present invention, the substructure is not carried out during the construction of the wall, but the substructure is carried out after the completion of the construction of the caisson in accordance with the shape of the basement in advance. The construction process can be simplified, and the entire on-site construction process including the submersion construction can be simplified, so that the on-site construction period is significantly reduced.

In the present invention, the basement is not particularly limited as long as it is a space formed under the ground for various purposes. Specifically, for example, a bedroom, an entertainment room, a study, a library , Daily living room, emergency living room such as shelter, storage and warehouse for daily necessities and food, chemical storage, water and sewage tank, fire prevention water tank, rainwater tank, oil tank and liquid chemical storage tank And the like.

In the present invention, the substantially same height means
This refers to the degree of height difference allowed in the construction, construction and civil engineering industries.

Hereinafter, the present invention, ie, the method of the present invention, the lower frame member of the present invention, the inner panel member of the present invention, the outer panel member of the present invention, and the separator of the present invention will be described in more detail.

In the method of the present invention, the method of forming the wall frame on the lower frame is not particularly limited. However, the inner panel is disposed on the assembled lower frame as a discard mold so that the inner panel has the same height or almost the same height as the wall frame. The inner panel construction to be raised at the same height, the inner reinforcement work to arrange the inner rebar, and the outer panel as a discard type standing on the lower frame at the same or almost the same height as the wall frame. Raising the outer panel work, outer reinforcement work to arrange the outer reinforcement, and placing concrete up to the height of the wall frame between the inner and outer panels raised on the upper frame with both the inner and outer reinforcements sandwiched, Consists of curing concrete work.

Among these wall frame works, the order of the inner panel work, the inner reinforcing work, the outer reinforcing work, and the outer panel work is not particularly limited. For example, after the inner panel work, the inner reinforcing work is performed. Then, after this inner reinforcement work, the outer panel construction can be advanced stepwise, and the outer reinforcement work can be gradually advanced from the part where the outer panel construction has been completed.

By adopting such a procedure, there is no need for an operator to enter the inside of the inner panel that has already been set up during the construction of the inner reinforcement, the outer reinforcement, and the outer panel. Workability of construction work, outer reinforcement work and outer panel work can be improved.

In the inner panel construction according to the present invention, as in the conventional construction method, it is possible to use a panel which is connected in multiple stages in the upper and lower directions, but the inner panel having the same height or almost the same height as the side wall is used. By using, the inner panel construction process can be simplified, and the inner panel can be raised to the same height or almost the same height as the wall frame in a short time.

Here, by forming the width of the inner panel to be the same as the width of the wall, the construction of the inner panel of the wall may be completed by starting up one inner panel. However, if a plurality of inner panel members having a width obtained by appropriately dividing the width of the side wall are used, the weight of one inner panel member can be reduced to a level that can be carried by one worker.

That is, in the inner panel construction according to the method of the present invention, a plurality of inner panel members having the same height or substantially the same height as the side wall and a width obtained by appropriately dividing the width of the side wall are provided in a predetermined order. When the inner panel is raised to the same height or almost the same height as the wall frame by being raised on the frame, the weight is such that one worker can carry one inner panel member. If heavy equipment cannot be used because there is not enough room around it, or heavy equipment cannot be used because there is no access route to the construction site, use heavy equipment due to schedule and construction cost Even if the heavy equipment cannot be used for some reason, such as when it is not possible, the inner panel work can be performed by a small number of workers.

Here, the order in which the inner panel members are set up on the lower frame is not particularly limited. However, when the inner panel members arranged adjacent to the corners of the lower frame are set up on the lower frame and connected to each other, they are connected to each other. The inner panels serve as a brace against the inclination of each other, and the two inner panels as a whole can exhibit the function of a column that is firmly independent on the lower frame.

Therefore, after the inner panel members arranged adjacent to the corners of the lower frame are raised on the lower frame and connected to each other,
By adopting a procedure in which other inner panel members are raised on the lower frame in the order of proximity to the inner panel members at these corners and connected in order, the inner panel can be connected to the lower frame without using upsets or supports. Since it can be formed on the upper side, it is possible to omit the construction period required for setting up and removing the belly and the support works.

As described above, in the case where the inner reinforcement is to be performed next to the inner panel construction, it is customary to support the inner reinforcement by the inner panel. For example, a part of the inner reinforcement is welded to the inner panel in advance. For example, in the inside reinforcement work at the construction site, a procedure of assembling the remaining inside reinforcement to the reinforcement fixed to the inner panel is adopted.

However, fixing a part of the inner rebar to the inner panel in advance is disadvantageous in improving the workability of the inner panel construction. Therefore, in the method of the present invention, the inner vertical rebar is vertically attached to the inner panel in advance. An insertion hole to be inserted in the direction is formed, and in the inside reinforcement work, the inside vertical reinforcement is inserted through the insertion hole of the inner panel attached to the lower frame, and the inside vertical reinforcement is arranged, and the inner arrangement is arranged. It is desirable to adopt a method of assembling an inner horizontal reinforcing bar to a vertical reinforcing bar.

The reason is that the inner vertical reinforcing bars are arranged simply by being inserted into the insertion holes of the inner panel, so that the inner vertical reinforcing bars can be arranged easily and in a short time.

In the method of the present invention, a separator (often called "separ" as a term in the field) is used to hold the inner and outer panels at a predetermined interval, and the inner vertical reinforcing bar is inserted vertically into the separator. An insertion hole is formed, and after connecting the separator to the inner panel raised on the lower frame, the inner vertical reinforcement is arranged by inserting the inner vertical reinforcement into the insertion hole of the separator. Similarly, it is possible to arrange the inner vertical reinforcing bar easily and in a short time.

As in the case of the inner vertical reinforcing bar, in the present invention, the outer vertical reinforcing bar can be arranged easily and in a short time. That is, an insertion hole through which the outer vertical reinforcing bar is vertically inserted is formed in the separator that holds the gap between the inner panel and the outer panel raised on the lower frame, and the inner panel raised on the lower frame. After connecting the separator, by adopting a method in which the outer longitudinal reinforcing bar is arranged by inserting the outer longitudinal reinforcing bar into the insertion hole, the outer longitudinal reinforcing bar can be easily arranged in a short time. It becomes like that.

In addition, an insertion hole through which the outer vertical reinforcing bar is inserted in the outer panel in the vertical direction is formed in the outer panel in advance, and the outer reinforcing bar is inserted through the insertion hole of the outer panel attached to the lower frame in the outer reinforcing work. Also, by arranging the outer vertical reinforcing bar and assembling the inner horizontal reinforcing bar to the arranged outer vertical reinforcing bar, the outer vertical reinforcing bar can be similarly easily and quickly arranged. is there.

By the way, in the outer panel work of the method of the present invention, similarly to the inner panel work, if the outer panel having the same height or almost the same height as the side wall is used, the outer panel work process can be simplified. In addition, the inner panel can be raised to the same height or almost the same height as the wall frame in a short time.

Here, the outer panel may be formed to have the same width as the one wall, so that one outer panel is started up to complete the outer panel work on the one wall. However, if a plurality of outer panel members having a width obtained by appropriately dividing the width of the side wall are used, the weight of one outer panel member can be reduced so that one worker can carry it.

That is, in the outer panel construction according to the method of the present invention, a plurality of outer panel members having the same height or almost the same height as the side wall and a width obtained by appropriately dividing the width of the side wall are provided in an arbitrary order. When the outer panel is raised to the same height or almost the same height as the wall frame by being raised on the frame, the weight is such that one worker can carry one outer panel member. If heavy equipment cannot be used because there is not enough room around it, or heavy equipment cannot be used because there is no access route to the construction site, use heavy equipment due to schedule and construction cost Even if the heavy equipment cannot be used for some reason, such as when the work cannot be performed, the outer panel work can be performed by a small number of workers.

In the outer panel construction, a plurality of outer panel members having the same height or substantially the same height as the side wall and a width obtained by appropriately dividing the width of the side wall are formed on the inner panel via the separator in a predetermined order. Whenever a predetermined number of outer panels are assembled to the inner panel, the outer reinforcing bars of the part where the outer panels are assembled are to be performed. Therefore, the bending of the outer horizontal reinforcing bar inserted and arranged between the inner and outer panels can be reduced, and the outer horizontal reinforcing bar can be easily arranged, which is advantageous.

Here, as described above, an insertion hole through which the outer vertical reinforcing bar is inserted in the up-down direction is formed in the outer panel in advance.
In the outer reinforcing work, the outer longitudinal reinforcing bar is inserted into the insertion hole of the outer panel attached to the lower frame to arrange the outer longitudinal reinforcing bar, and the inner lateral reinforcing bar is attached to the arranged outer longitudinal reinforcing bar, Since the arrangement of the outer vertical reinforcing bars can be performed easily and in a short time, the whole outer reinforcing work can be performed easily and in a short time.

By the way, in the method of the present invention, after the inner panel construction, the inner reinforcement construction, the outer reinforcement construction, and the outer panel construction are completed, concrete is laid between the inner and outer panels to the height of the wall frame by concrete construction. Cast and cure.

Therefore, the concrete construction process is simpler than the conventional method in which the concrete construction at the lower part of the caisson and the concrete construction at the upper part of the caisson are performed.
In addition, the casting time and the curing time can be reduced, for example, from 5 to 7 days.

Further, since the concrete of the wall skeleton is not transferred, it is not necessary to clean the connection surface, so that the process can be simplified and the construction period can be shortened, and there is no risk of foreign matter entering the connection surface. In addition, there is no danger that cracks will be induced by the contaminants or that the groundwater will leak into the basement due to the cracks.

In addition, since the caisson has high rigidity, uneven settlement is unlikely to occur, and rubble and the like can be easily dealt with by digging only at that location.

In the method of the present invention, when a groove is formed in the lower portion of the lower frame and a pipe that connects the groove and the upper side of the side body is buried in the side body, the soil is buried in the soil through the pipe and the groove. It can supply the improvement material, pump up the groundwater, and since the pipe is not exposed outside the wall frame, there is no danger of the pipe being damaged during the submersion work.

In the method of the present invention, the method of completing the wall frame on the lower frame is not limited to the method described above.
For example, in the wall frame construction, an inner panel construction in which the inner panel is raised to the same height or almost the same height as the wall frame as a discarded type on the lower frame, and an inner reinforcing bar construction for arranging the inner reinforcing bar. Outer reinforcement work to arrange the outer reinforcement, and outer panel construction to raise the outer panel as a disposable mold on the lower frame to the same height or almost the same height as the wall frame are performed in this order. After concrete, concrete is poured to the height of the wall frame between the inner and outer panels raised on the upper frame with the inner and outer rebars sandwiched, and curing is performed. After the outer reinforcement work,
After this outer reinforcing work, the inner panel work is advanced in stages.
It is also possible to adopt a method in which the inner reinforcement work is advanced step by step from the part where the inner panel work has been completed.

Next, the lower frame member of the present invention comprises an upper surface plate having a width of the side wall of the basement or an appropriately divided length and a width larger than the wall thickness of the basement, and a width direction of the upper surface plate. An outer surface plate is provided vertically extending from one end edge, and a groove side plate is provided that extends obliquely upward from a lower edge of the outer surface plate below the upper surface plate.

According to this lower frame member, a square or rectangular lower frame can be assembled in plan view on the basement site by connecting the lower frame member via an appropriate joining plate. After the side wall is completed, the above object can be achieved by implementing the method of the present invention for digging up the earth and sand in the lower frame.

Further, according to the lower frame member, the lower edge of the outer plate is reinforced by the groove side plate, so that the outer plate is hardly deformed when excavating the sand at the bottom of the caisson, and the caisson is sunk into the soil with stability. be able to.

Further, according to this lower frame member, since a single-flow V-shaped groove is formed between the outer surface plate and the groove side plate, before the concrete is cast, a gap is formed between the outer surface plate and the inner plate. Provide a continuous pipe above the concrete casting surface from the formed groove, when digging the ground in the lower frame, supply the soil improvement material into the soil through this pipe and groove, or
Spring water can be discharged, and after construction of the basement, the groundwater under the floor structure of the basement and outside the side wall is collected in the ditch,
Can be pumped to the ground via a pipe.

In this lower frame member, if an inner surface plate is provided so as to protrude from the other edge in the width direction of the upper surface plate, one edge in the width direction of the upper surface plate is formed by the outer surface plate and the other edge in the width direction. Since the edge is reinforced by the inner face plate, the lower frame member or the lower frame assembled with the lower frame member after the side wall is formed on the lower frame or after the side wall is formed on the lower frame is prevented from bending. The sidewall can be completed accurately on the lower frame.

Next, in order to achieve the above object, the inner panel member of the present invention has the same height as or substantially the same as the height of the side wall of the basement, and the width of the side wall or a width obtained by appropriately dividing the height. A main plate having at least three edges including upper and lower edges of the main plate and at least one portion therebetween, and extending in the width direction, and each lateral rib projecting outward.
A technical means is adopted in which an insertion hole for inserting the inner vertical reinforcing bar is formed in each horizontal rib excluding or including the lower horizontal rib.

According to this inner panel member, in the case of the inner panel member having the width of the side wall, one inner panel member is erected on the lower frame, and the lower edge is fixed to the lower frame. Also, in the case of an inner panel member having a width obtained by appropriately dividing the width of the side wall, a predetermined number of inner panel members are arranged in the width direction, and each of the inner panel members is erected on the lower frame, and the lower edges thereof are connected to the lower frame. , The inner panel can be raised on the lower frame at the same height or almost the same height as the side wall.

In particular, according to the inner panel member having the same height or almost the same height as the side wall of the basement and the width of the side wall appropriately divided, the weight of the single item can be handled by one worker. This allows, for example, one worker to support this inner panel member upright on the lower frame, and another worker to use the lower edge of the lower panel with bolts, nuts and rivets. It can be fixed by welding or the like, and the basement can be constructed even in a narrow site where heavy equipment cannot be entered.

Further, according to the inner panel member, the inner reinforcing bar, the separator, the outer panel, and the outer reinforcing bar are assembled to the inner panel which is raised on the lower frame at the same height or almost the same height as the side wall. Then, concrete is poured between the inner and outer panels to the height of the side wall and cured, whereby the side wall can be completed on the lower frame at a stroke, and the method of the present invention can be carried out.

In the inner panel member of the present invention, when an insertion hole into which the end of the separator is inserted from above is formed in at least one of the lateral ribs, the end of the severator is inserted into the insertion hole from above. The separator can be assembled to the inner panel member easily and in a short time, which is advantageous in shortening the construction period.

Next, in order to achieve the above object, the outer panel member of the present invention has the same height as or substantially the same as the height of the side wall of the basement, and the width of the side wall of the basement or a width obtained by appropriately dividing the same. Technical means is adopted in which a main plate and at least one insertion hole into which the end of the separator is inserted from above are provided at appropriate positions in the height direction and the width direction of the main plate.

According to this outer panel member, in the case of the outer panel member having the width of the side wall, one outer panel member stands on the lower frame and the width of the side wall is appropriately divided. In the case of the outer panel member having a, a predetermined number of outer panel members are arranged in the width direction, and each is erected on the lower frame, and the other end of the separator having one end connected to the inner panel is inserted from above into the insertion hole. Accordingly, an effect is obtained that can be assembled easily and at a predetermined interval on the inner panel in a short time.

In particular, according to the outer panel member of the present invention having the same height or almost the same height as the side wall of the basement, and the width of the side wall appropriately divided, the weight of a single item can be reduced by one worker. Can be handled so that one worker can hold the outer panel member, stand on the lower frame, and insert the end of the separator connected to the inner panel into the insertion hole from above. Thereby, it can be easily and quickly assembled to the inner panel via the separator. In addition, there is no need to use heavy equipment for assembling the outer panel, and the basement can be constructed even on a narrow site where heavy equipment cannot be inserted.

In this outer panel, lateral ribs extending in the width direction are protrudingly provided at a plurality of places at appropriate intervals in the vertical direction on the inner surface of the main plate, and an insertion hole through which an outer vertical reinforcing bar is inserted into each lateral rib. Is formed, by inserting the outer longitudinal reinforcing bar through the insertion hole, the outer longitudinal reinforcing bar can be arranged easily and in a short time.

Incidentally, in the outer panel member of the present invention, the method of forming the insertion hole into which the end of the separator is inserted from above is not particularly limited. For example, at least one lateral side extending in the width direction on the inner surface of the main plate. A rib is protruded, and an insertion hole into which the end of the separator is inserted from above is formed in at least one of the horizontal ribs, or the main plate is formed of a mold steel plate waving in the width direction. By fixing the locking member to the side surface, an insertion hole into which the end of the separator is inserted may be formed between the locking member and the main plate.

Next, in order to achieve the above object, the separator of the present invention is provided with a main portion for determining the interval between the inner and outer panels, and is continuously provided downward from opposite ends of the main portion. Technical means is adopted in which a panel, an outer panel member, an inner panel, or an insertion piece inserted from above into an insertion hole formed in the inner panel member is employed.

According to the severator, for example, after the outer panel member (or the outer panel) is placed on the lower frame in opposition to the inner panel member (or the inner panel) raised on the lower frame, The insertion piece at one end is inserted into the insertion hole formed in the inner panel member (or inner panel) from above, and before and after this, the insertion piece at the other end is inserted into the outer panel member (or outer panel).
Inserting the outer panel into the inner panel at a predetermined interval can be performed easily and in a short time by inserting the outer panel into the insertion hole formed from above.

In the main part of the separator, an insertion hole for inserting an inner vertical reinforcing bar, or an insertion hole for inserting an outer vertical reinforcing bar,
Alternatively, an insertion hole for inserting the inner vertical reinforcing bar and an insertion hole for inserting the outer vertical reinforcing bar can be formed.If an insertion hole for inserting the inner vertical reinforcing bar is formed, the inner vertical reinforcing bar is inserted into the insertion hole. By doing so, it is possible to arrange the inner vertical reinforcing bar easily and in a short time, and when an insertion hole for inserting the outer vertical reinforcing bar is formed, by inserting the outer vertical reinforcing bar into this insertion hole, In addition, the outer longitudinal rebar can be easily and quickly arranged.

As described above, according to the method of the present invention, the lower frame is assembled on the site of the basement, the side walls are completed on the lower frame at once, and the earth and sand in the lower frame is dug down. For example, assembling the inner and outer panels that are discarded, arranging reinforcing bars between the inner and outer panels, placing and curing concrete between the inner and outer panels. Thus, it is possible to obtain an operation capable of shortening the construction period required for excavation of the caisson bottom.

Further, the lower frame member of the present invention comprises an upper plate having a side wall width of the basement or an appropriately divided length, a width larger than the wall thickness of the basement, and one end in the width direction of the upper plate. Since it is equipped with an outer panel hanging down from the edge and a groove side panel that extends diagonally upward from the lower edge of the outer panel below the upper panel, it is connected to the basement site by a suitable connecting plate, so that the basement site can be viewed in plan. In the above, a square or rectangular lower frame can be assembled, and after completing the side walls on the frame at once, the method of the present invention for digging earth and sand in the lower frame can be performed to achieve the above object. A possible function is obtained.

In this case, the reinforcement of the inner reinforcing bar at the corner portion is performed following the reinforcing bar of the inner reinforcing bar at the wall surface. However, the reinforcement at the corner portion is finished after the outer panel and the outer reinforcement are finished. You may go from.

The diameters and the spacing of the inner vertical reinforcing bars 3A and the inner horizontal reinforcing bars 3B are design items.
mm, bar spacing is 200mm in horizontal direction, 200mm in vertical direction
It is said. Further, the inner vertical reinforcing bar 3A may be fixed to the inner panel member 2A in advance at a factory by, for example, welding.

Further, after attaching the inner vertical reinforcing bar 3A, the caps 2D, 2E and 2F are put on the upper edge of the inner panel 2A and fixed to the inner panel member 2A with bolts and nuts.
Thereby, the upper edges of the adjacent inner panel members 2A are firmly connected to each other via the corner caps 2D and the intermediate caps 2E, 2F.

Further, in this embodiment, an upper anchor 19E and a long bolt 19F are screwed to the long nut 19D as required.

[0130] When the above inner reinforcement work is completed, outer panel / outer reinforcement work is performed. In this outer panel / outer reinforcement work, the outer panel 4 assembled to the lower frame 1 is attached to one wall. May be one, but here the inner panel 2
For the same reason as comprising a plurality of inner panel members 2A,
A plurality of outer panel members 4A constitute one outer panel 4.

That is, as shown in the perspective view of FIG. 15, the outer panel member 4A has the same height as the side wall of the basement.
A main plate 4a having a width obtained by appropriately dividing the width of the side wall of the basement
And an intermediate horizontal rib 2 of the inner panel member 2a on the inner surface thereof.
Strip plate material 4 welded to positions corresponding to d, 2e and 2f
b, 4c and 4d, weighing about 15.5 kg.

The main plate 4a is formed of a shaped steel plate (here, a V-shaped deck steel plate) waving in the width direction, such as a keystone plate or a deck steel plate. Then, the strips 4b, 4
An insertion hole 4e for inserting the end of the separator 5 shown in the perspective view of FIG. 16 is formed between c and 4d and the groove of the main plate 4a.

The separator 5 includes a main portion 5a having substantially the same length as a predetermined wall thickness, and insertion pieces 5b extending downward from both ends in the length direction.
By inserting the insertion piece 5b at one end into the insertion hole 2i of the inner panel member 2A raised above the inner panel member 2A, the inner panel member 2A is supported.

By the way, the main plate 5b of each separator 5 is formed with an insertion hole 5c through which an outer vertical reinforcing bar 3C and an interval holding member 6 for suspending the outer horizontal reinforcing bar 3D at a predetermined vertical interval are formed. Separator 5 attached to member 2A
The outer vertical reinforcing bar 3C and the spacing member 6 are inserted through the insertion hole 5c.

Although it is possible to freely select which of the outer vertical reinforcing bar 3C and the spacing member 6 is inserted into the insertion hole 5c first,
In this embodiment, the space holding tool 6 is first inserted into the insertion hole 5c due to dimensional problems of the outer vertical reinforcing bar 3C, the insertion hole 5c, and the space holding tool 6, and the outer vertical reinforcing bar is inserted into the gap left in the insertion hole 5c. 3C is inserted.

As shown in the cross-sectional view of FIG. 17, the spacing member 6 includes a vertically extending band-shaped strap 6a and a predetermined distance from the strap 6a by, for example, punching. A predetermined number of hooks 6 set in the direction
b, and a connecting portion 6c formed by bending the upper end of the strap 6a inward of the wall, and fixing the connecting portion 6c to the upper end portion of the outer vertical reinforcing bar 3C using, for example, a number line, thereby connecting each hook 6b. It is located at a predetermined height.

The outer vertical reinforcing bar 3C can be connected to the upper anchor 19E, the long bolt 19F, or the like with a line, but it is sufficient to simply insert the outer reinforcing bar 3C into the insertion hole 5c of the separator 5.

The outer horizontal reinforcing bars 3D can be arranged at any time after the arrangement of the spacing retainers 6 and the arrangement of the outer longitudinal reinforcing bars 3C are performed. After the arrangement of 6 and the arrangement of the outer vertical reinforcing bar 3C are made,
Each time a predetermined number (for example, two or three) of the outer panel members 4A are assembled, the outer horizontal reinforcing bars 3D are arranged.

When a large number of outer panel members 4A are assembled, it is necessary to lengthen the outer horizontal reinforcing bars 3D correspondingly, and the outer horizontal reinforcing bars 3D inserted between the inner and outer panel members 2A, 4A are bent. This is not preferable because it increases the workability. In addition, if the outer lateral reinforcing bar 3D is assembled every time one outer panel member 4a is assembled, it is not preferable because the operation becomes complicated.

The outer panel member 4A is assembled by attaching a waterproof seal in the form of a soft tape to the upper surface of the lower frame 1 and then placing the outer panel member 4A on the waterproof seal so as to face the outside of the inner panel member 2A. 4 and one end is inserted into the insertion hole 2 of the inner panel member 2A.
i, the other end of the separator 5 is lifted, the outer panel member 4A is sufficiently brought close to the inner panel member 2A, and then the other end of the parator 5 is lowered to insert the other end into the insertion hole 4e of the outer panel member 4A. The procedure is simple and quick by inserting the insertion piece 5b.

It should be noted that adjacent outer panel members 4A are stopped merely by overlapping their side edges.

The spacing in the wall width direction in which the spacing members 6 are arranged may be larger than that of the separators 5, for example, the spacing members 6 may be arranged on every other separator 5. .

Further, the outer vertical reinforcing bar 3C and the outer horizontal reinforcing bar 3D
Are also design items, for example, the rebar diameter is 1
3mm, bar spacing 610mm in horizontal direction, 200 in vertical direction
mm.

The space between the outer panel 4 and the inner panel 2 is opened outward at the end of the main frame 11 in the wall width direction. The open surface to the corner cover 4 shown in the perspective view of FIG.
B closes.

That is, the corner cover 4B has a plate member 4f bent in an L-shape in plan view and a plate member 4f.
