  In the proposal of the above document disclosure, there is basically no problem in that the crushed pillar, that is, the crushed lump does not come out of the structure, but considering the actual construction work of the structure. , It may be pointed out that there is a minor bug.

  That is, in the proposal of the above-mentioned literature disclosure, particularly in the place disclosed in Patent Document 2, the crushed enclosure, that is, the crushed lump is brought down to the inside of the structure, the crushed lump is outside the structure. It is normal to use a tow rope from the inside of the structure to prevent it from falling out of the structure, so that it is normal to prevent the structure from falling to the outside in advance. Depends largely on the skill level of an operator who operates a heavy machine as a crushing means.

  On the other hand, if the person operating a heavy machine is not an expert, that is, if the person is an unskilled person, omitting the use of the above-mentioned tow rope cannot depend on the skill level of the operator operating the heavy machine. It is feared that the mass will not fall inside the structure and come out of the structure.

  The fact that the shredded mass comes out of the structure may worsen the so-called timing even if an expert maneuvering heavy machinery pays the best effort and uses the above-mentioned tow rope together. If the crushed lump comes out of the structure, for example, the work scaffold provided outside the structure may be damaged or collapsed.

  The present invention was devised in view of the above-described circumstances, and the object of the present invention is in a construction in which an existing structure is crushed from the inside of the structure and disassembled, and the crushed lump is outside the structure. An object of the present invention is to provide a disassembling method and a disassembling apparatus that are optimal for preventing the outflow.

One means of the present invention for achieving the above-described object is to provide crushing means comprising heavy machinery inside a structure having a plurality of floors, and that the outer surface of the structure is exposed to the outside of the structure. A restricting means for blocking, and the restricting means includes a secondary pillar provided on the outer surface of the structure, and the secondary pillar is detachably connected to each of the plurality of floors by a connecting means; In the dismantling apparatus that crushes the casing that forms the structure in the state provided on the outer surface with the crushing means from the inside of the structure,
The coupling means includes a screw rod that passes through the housing and the sub-post, and a fixing nut that is screwed to one end and the other end of the screw rod. And
Similarly, the other means is provided with crushing means consisting of heavy machinery inside the structure having a plurality of floors, and provided with regulation means for preventing the outer surface from coming out of the structure on the outer surface of the structure, In a state where the restricting means is provided with an auxiliary column provided on the outer surface of the structure, the auxiliary column is detachably connected to each of the plurality of floors by the connecting means, and the restricting means is provided on the outer surface. In the dismantling apparatus that crushes the casing forming the construct from the inside of the construct with the crushing means,
A holding metal fitting in which the connecting means holds the sub-post, a screw rod connected to the holding metal fitting and penetrating the housing, and a fixing nut screwed to a rear end portion of the screw rod. It is characterized by having.
Similarly, the other means is provided with crushing means consisting of heavy machinery inside the structure having a plurality of floors, and provided with regulation means for preventing the outer surface from coming out of the structure on the outer surface of the structure, In a state where the restricting means is provided with an auxiliary column provided on the outer surface of the structure, the auxiliary column is detachably connected to each of the plurality of floors by the connecting means, and the restricting means is provided on the outer surface. In the dismantling apparatus that crushes the casing forming the construct from the inside of the construct with the crushing means,
An arm part through which the connecting means is formed so that the insertion hole formed in the casing can be inserted and removed freely in the thickness direction of the casing, and the casing which is provided at one end of the arm part and forms the insertion hole. And a fixing portion provided at the other end portion of the arm portion and facing the locking portion, and the fixing portion forms the insertion hole between the locking portion and the locking portion. It is characterized by comprising a fixing means for enabling the holding of the housing and a connecting mechanism for enabling detachable connection of the auxiliary strut to the fixing portion with the auxiliary strut.

  Therefore, in the present invention, since the structure is provided with a regulation means for preventing the outer surface from coming out of the structure on the outer surface, the casing forming the structure is crushed by the crushing means provided inside the structure. In this case, the outer surface provided with the above-mentioned restricting means does not come out of the structure, and the housing provided with the outer surface that does not go outside, or the housing provided with the outer surface continuous to the outer surface that does not go outside, that is, The shredded enclosure is prevented from going outside the structure.

  As a result, according to the present invention, when the structure forming the structure is crushed from the inside of the structure by the crushing means provided inside the structure and the structure is disassembled, the crushed structure, that is, the crushed lump is For example, it may not be necessary to provide a tow rope for preventing the collapse of the structure of the crushed frame to the outside, and the dismantling work can be simplified. Become.

  And since it is possible to prevent the crushed lump from coming out of the structure without using the above-mentioned tow rope, the crushing operation of the skeleton without depending on the skill level of the crushing means, for example, the operator operating the heavy machinery That is, the dismantling work of the structure becomes possible.

  In addition, since the crushed lump can be prevented from coming out of the structure, there is no danger that the work scaffold provided outside the structure will be damaged or collapsed due to the crushed lump coming out of the structure. It will be enough.

  Hereinafter, the present invention will be described based on the illustrated embodiments. First, in the dismantling method of the present invention, in the dismantling method of crushing the casing forming the construct from the inside of the construct with the crushing means provided inside the construct, the outer surface is exposed to the outside of the construct. There is a feature in that a restricting means for blocking is provided, and the casing is crushed by the crushing means in a state where the restricting means is provided on the outer surface of the structure.

  And the dismantling method of this invention can be embodied by the dismantling apparatus of this invention. Therefore, hereinafter, the disassembling apparatus of the present invention will be described, and the disassembling method of the present invention will be described together.

  As shown in FIG. 1, the dismantling apparatus of the present invention includes a crushing means 1 that crushes a casing (see reference signs A <b> 1 to A <b> 4 in FIG. 1) provided inside a construct and crushes the construct from inside the construct. And a regulating means 2 that is provided on the outer surface (not shown) of the structure and prevents the outer surface of the structure from coming out of the structure when the housing is crushed from the inside of the structure by the crushing means 1. .

  In the illustrated embodiment, in order to realize a preferable embodiment of the disassembly method of the present invention, the disassembly apparatus of the present invention includes the crushing means 1 and the restriction means 2 described above, as shown in FIG. In addition, connecting means 3 and 4 for connecting the regulating means 2 to the outer surface of the structure are provided, and further, a working scaffold 5 is provided on the outside of the structure, and the working scaffold 5 is connected to the regulating means 2 described above. Connecting means 6 and 7 are provided. In the disassembling apparatus of the present invention, as shown in another embodiment of FIG. 13, the regulating means 2 can be coupled to the outer surface of the structure also by the coupling means 10.

  Although the structure is shown as building A in the drawing, from the viewpoint of enabling the present invention, that is, the dismantling method and the dismantling apparatus, the structure is a tower other than building A. Or a retaining wall.

  And although the building A which is the structure to show in figure shows the housing | casing using reinforced concrete, from the implementation of this invention, the housing of the building A may be formed using the steel frame.

  By the way, when the housing of the building A is formed of a steel frame, the dismantling of the housing is fusing instead of crushing, and the fusing means corresponding to the crushing means 1 has a configuration capable of practicing fusing of the steel frame. It is.

  By the way, in the present invention, the expression “inside” and “outside” of the structure is expressed. When the structure includes a so-called enclosed space such as a building A or a tower, the enclosed space is expressed as “ In other words, the space that is not enclosed is called “outside”.

  On the other hand, if the structure only divides the space into front and rear or left and right, such as a retaining wall, if it corresponds to one side “inside”, the other side is equivalent to “outside” Therefore, the implementation of the present invention will not be hindered.

  Returning, the structure, that is, the building in the building A, forms the building A. In FIG. 1, the pillar indicated by reference numeral A1, the beam indicated by reference numeral A2, the wall indicated by reference numeral A3, and also indicated by reference numeral A4. The floor corresponds. Although not shown, the ceiling can be called a floor A4 depending on how it is seen, and becomes a box.

  On the other hand, the building A shown in the figure has a plurality of floors in the vertical direction in the implementation of the present invention, that is, a multi-story building, but from the viewpoint of making it possible to provide the regulating means 2. For example, even if the building A is not a multi-storey building but a so-called one-story building or a two-story building, it is a matter of course that the implementation of the present invention is not hindered.

  In the illustrated embodiment, the crushing means 1 constituting the dismantling apparatus of the present invention is a self-propelled so-called heavy machine that can freely move inside the building A. The heavy machine turns horizontally and vertically. The arm 11 is provided with a freely swingable arm, and the arm 11 is provided with a crushing tool 12 at the tip thereof that enables crushing of the housing.

  As the crushing tool 12, a biaxial crushing tool or a hammer type crushing tool is a candidate, and in the case of a biaxial crushing tool, the housing is sandwiched between them. In addition, the hammer can be crushed while suppressing the generation of noise, and the hammer-type crusher has a so-called flaw so that fine crushing can be easily practiced as compared with the biaxial crusher.

  As shown in FIG. 1, the crushing means 1 includes a hammer-type crushing tool as the crushing tool 12, and crushing the base portion of the column A <b> 1 by the hammer-type crushing tool, that is, from the inside of the building A. It is said that partial crushing can be practiced.

  Regardless of whether the crushing tool 12 is composed of a biaxial crushing tool or a hammer type crushing tool, in the present invention, crushing of the housing by the crushing means 1 is practiced from the inside of the building A, that is, crushing work, The crushing waste accompanying the crushing work, that is, the concrete waste and the concrete lump are prevented from coming out of the building A.

  When the crushing of the frame by the crushing means 1 is practiced from the inside of the building A, it is obvious that it is advantageous in preventing the concrete debris and concrete lump accompanying the crushing operation of the frame from coming out of the building A. It is.

  Therefore, even in the present invention, in principle, the building forming the building A is crushed from the inside of the building A. In order to embody this, the dismantling method and the dismantling apparatus of the present invention are used. The crushing means 1 is provided inside the building A.

  Although not shown in the figure, until the crushing means 1 crushes the base part of the pillar A1 which is the casing (see FIG. 1), the heavy machine as the crushing means 1 is introduced inside the building A. The wall A3, which is a skeleton, is crushed from the outside of the building A. At this time, the concrete lump accompanying the crushing operation of the wall A3 falls to the inside of the wall A3, that is, the inside of the building A. Of course, the concrete block is prevented from going outside the building A.

  Moreover, although it is not shown in figure, it is not shown in the inside which introduces a heavy machine, although it does not show in figure until it reaches the root part of pillar A1 which is a housing | casing by the heavy machine which is introduced inside the building A, ie, the arranged crushing means 1 The ceiling floor covering the upper side is crushed, and the beam A2 following the ceiling floor is broken so that the pillar A1 stands up continuously on the wall A3 as shown in FIG.

  In addition, as a measure for introducing the heavy machinery as the crushing means 1 into the inside of the building A, the heavy machinery is once disassembled into so-called component parts, the disassembled component parts are carried into the inside of the building A, and the heavy machinery is assembled. Of course, the introduction of heavy machinery may be executed.

  Next, the regulating means 2 will be described. In the present invention, the regulating means 2 is configured such that when the building A is crushed from the inside, that is, the casing forming the building A is crushed by the crushing means 1 described above from the inside of the building A. When it is done, it is intended to prevent the crushed enclosure, that is, the concrete block, from coming out of the building A.

  Therefore, it is assumed that the restricting means 2 is integrally connected to the outer surface of the building A, that is, the outer surface of the housing. In the case of the housing to which the restricting means 2 is connected, the restricting means 2 is crushed from the inside of the building A. Even if it is done, for example, it is made not to come out of the building A in the state where it became a concrete lump.

  By the way, as shown in FIG. 2 and FIG. 3, in the state where the regulating means 2 is connected to the outer surface of the wall A3 which is the skeleton of the building A, even if the wall A3 is crushed, the crushed wall A3. Of course, the outer surface of the door does not come out of the building A due to the connection of the regulating means 2.

  Incidentally, in FIG. 3, the restricting means 2 is provided in such a manner as to sandwich the column A1 from the left and right sides, but this is an example, and the restricting means is provided only on either the left or right side as required. Of course, 2 may be provided.

  On the other hand, in a state in which the regulating means 2 is connected to the outer surface of the wall A3 which is the housing of the building A, the housing having the outer surface continuous to the wall A3, that is, the column A1 which is the housing continuing to the wall A3 is crushed. However, since the outer surface of the wall A3 is connected to the regulating means 2 and does not come out of the building A, the outer surface of the pillar A1 continuous to the wall A3, that is, the crushed pillar A1 is also outside the building A. As a result, the crushed frame pillar A1 is prevented from going outside the building A.

  Note that the restriction means 2 is provided in order to prevent the crushed enclosure from coming out of the building A. Therefore, the restriction means is provided on the wall A3 (see FIG. 3B). Instead, although not shown, it may be said that it may be provided on the pillar A1 or the beam A2 or the floor A4 which is a crushed casing.

  By the way, even when the column A1 is crushed, the regulating means 2 is provided on the column A1, but when the column A1 is crushed, the crushing operation of the column A1 proceeds smoothly, and then the column A1 to be crushed The regulation means 2 will be separated from the outer surface, and as long as this is the case, it can be said that the crushed column A1 cannot be prevented from coming out of the building A.

  However, since the regulation means 2 is basically provided across a plurality of floors from the lower floor to the upper floor, even if the upper end is separated from the outer surface of the pillar A1, the lower end is connected to the pillar A1, In other words, it will be maintained in a self-supporting state, and the pillar A1 crushed in a state separated from the regulating means 2 can be prevented from coming out of the building A.

  Further, when the restriction means 2 is provided on the wall A3 when the pillar A1 is crushed, the pillar A1 is crushed because the crushed pillar A1 continues to the wall A3 on which the restriction means 2 is provided. However, it is possible to prevent the crushed pillar A1 from going out of the building A without any restrictions.

  Therefore, according to a preferred embodiment of the present invention, the regulating means 2 may be provided on the wall A3 (see FIG. 3 (B)). However, according to the intention of the present invention, as described above, Of course, even if the regulating means 2 is provided on the pillar A1, the beam A2, or the floor A4, the present invention can be implemented.

  The restricting means 2 that functions as described above is detachably provided on the outer surface of the building A by the connecting means 3 and 4 and the connecting means 10 as shown in FIG. The restriction means 2 is provided on the outer surface of the building A so as to be separable, so that the restriction means 2 can be reused in another dismantling work, of course, but the dismantling work in progress This is also to enable so-called rearrangement of the regulating means 2 in FIG. The reordering of the regulation means 2 will be described later.

  Returning, in the illustrated embodiment, the restricting means 2 is provided with the auxiliary column 21 formed in the truss structure as shown in FIGS. 2 and 3, and a plurality of the auxiliary columns 21 are connected in the vertical direction. It is provided on the outer surface of the building A.

  As shown in FIG. 4, the auxiliary strut 21 is in a state in which a pair of grooved steel shapes 22 have grooves (not shown) facing each other with an interval (see (C) in FIG. 4). Therefore, it is assumed that they are connected by a pair of lattices 23 (see (A) in FIG. 4).

  The grooved steel 22 is formed of a light steel frame having a shallow U-shaped cross section, and the lattice 23 is welded to the flange portion 22a of the grooved steel 22 by bending the bar steel in a zigzag shape.

  Since the auxiliary strut 21 formed as described above has a truss structure, it is lightweight while having a predetermined self-supporting property and mechanical strength, and is advantageous in facilitating handling by an operator, for example. .

  Incidentally, from the viewpoint of configuring the regulating means 2 and having a predetermined self-supporting property and mechanical strength, the sub-posts 21 are not shown in the figure instead of being formed in the truss structure. It may be said that it may be made of lightweight H-shaped steel. However, as described above, when emphasis is placed on facilitating handling by workers, it is preferable that the sub-post 21 is formed in the truss structure shown in the figure.

  Returning, in the illustrated embodiment, the auxiliary struts 21 are provided on the outer surface of the building A (see FIG. 1) as the restricting means 2 in a state of being connected in the vertical direction. If it is provided, that is, in terms of the function as the regulating means 2, it can be said that the auxiliary strut 21 may be of a so-called single specification that straddles a plurality of floors of the building A.

  However, in the case of the so-called single specification in which the auxiliary support column 21 straddles a plurality of floors of the building A, it becomes so long that the weight becomes unnecessarily large and the handling by the worker is likely to be difficult. is assumed.

  Taking this into consideration, the auxiliary strut 21 having the above truss structure is set to a length that is easy for an operator to handle, such as approximately 1.0 meter, approximately 1.5 meters, or approximately 2.0 meters. It is preferable that a plurality of these are connected and have a predetermined length.

  Then, the so-called short auxiliary column 21 is lowered downward when the use is finished, that is, the lowest auxiliary column 21 which is still provided on the outer surface of the building A by the refilling work. It will be suitable for being connected to 21. In the disassembling method of the present invention, there is no limitation on the timing at which the auxiliary strut 21 is further connected to the lowermost sub strut 21 and is arbitrary.

  Incidentally, even when the auxiliary column 21 is formed as a so-called single thing straddling a plurality of floors of the building A, for example, it can be suspended by use of a crane or the like and provided on the outer surface of the building A. Of course, it does not impede the implementation of the invention.

  In addition, in the case where it is set to provide the auxiliary column 21 that is long by using a crane or the like on the outer surface of the building A, a plurality of the above-described short-shaped ones are connected to each other on the ground or the like. Of course, it is also possible to suspend it by using a crane or the like and provide it on the outer surface of the building A.

  Further, for connecting the plurality of sub-columns 21 formed in a short length in the vertical direction, basically any means may be selected, but in the illustrated embodiment, as shown in FIG. The plate 24 forming the upper and lower ends of the auxiliary support column 21 is provided with bolt insertion holes 24a penetrating the four corners in the vertical direction at so-called four corners, and bolts (not shown) are inserted into the bolt insertion holes 24a. It is preferable to connect the upper and lower auxiliary struts 21 by screwing a nut (not shown).

  Although a plurality of sub-columns 21 formed in a short length are connected in the vertical direction, instead of the configuration of the plate 24 and the bolt insertion hole 24a, although not shown, for example, the sub-columns 21 that are vertically arranged Of course, an arbitrary connection structure such as connection with a connection bracket or a connection plate may be used.

  As described above, the connecting means 3 and 4 and the connecting means 10 are for detachably connecting the auxiliary column 21 constituting the restricting means 2 to the outer surface of the building A. As a matter of course, the auxiliary strut 21 can be formed in a short length, separated after use on the upper floor, and separated. Thus, the work of connecting the sub-posts 21 to the lower floor, that is, the rework work is made possible.

  Below, the connection means 3 and 4b are demonstrated a little. The connecting means 10 will be described later. Each of the connecting means 3, 4, 10 is made of a hard material typified by a metal material, that is, in the illustrated embodiment, is made of metal.

  First, as shown in FIGS. 5A and 5B, the connecting means 3 includes a thread rod 31 and fixing nuts 32 and 33 that are screwed to both ends of the thread rod 31. The thread rod 31 has a sufficient length to allow the fixing nuts 32 and 33 to be screwed, and the thread rod 31 is sufficient to penetrate the support column 21 and the wall A3 which is the housing. Is formed.

  Incidentally, the direction in which the thread rod 31 penetrates the auxiliary column 21 may in principle be either the short side or the longitudinal direction in the cross section, but in the illustrated embodiment, the auxiliary column 21 is used. Is brought into contact with the outer surface of the building A, the longitudinal axis of the sub-posts 21 is along the direction penetrating the wall thickness of the wall A3 as the building A. It penetrates the longitudinal direction of the column 21.

  Here, the abutment of the auxiliary column 21 on the outer surface of the building A will be described. The restriction means 2 of the present invention is provided on the outer surface of the building A as described above.

  The fact that the auxiliary column 21 is provided on the outer surface of the building A means that the auxiliary column 21 is connected to the outer surface of the building A. However, as is well known, the outer surface of the building A is slightly smaller. It is a normal state that it becomes an uneven surface.

  That is, in providing the regulating means 2 on the outer surface of the building A, the regulating means 2 is preferably provided in direct contact with the outer surface of the building A. However, as described above, the outer surface of the building A is Therefore, all of the plurality of restricting means 2 are directly brought into contact with the outer surface of the building A and connected to each other, and even if one restricting means 2 is in the vertical direction, It is considered that it is practically difficult to directly contact and connect the outer surface.

  Therefore, when the restricting means 2 is provided on the outer surface of the building A and there is a gap between the restricting means 2 and the building A, a spacer or wedge formed of any material is used. Therefore, it is preferable to eliminate the gap and connect them.

  Incidentally, in the figure, the auxiliary column 21 is in a state of being in direct contact with the outer surface of the building A, but this is because there is a gap between the auxiliary column 21 and the building A. In order to avoid complication of the drawing due to the state in which the space is filled with a spacer or the like, the meaning of excluding the application of the present invention when there is a gap between the auxiliary strut 21 and the building A Of course not.

  Returning to FIG. 5, the auxiliary rod 21 is provided with a guide pipe 25 between the pair of grooved steel 22 so as to facilitate the threading operation of the thread rod 31. However, if this guide pipe 25 is present, the operation of penetrating the thread rod 31 can be performed quickly.

  Therefore, if the work is not required to be quick, although not shown, a hole for inserting the threaded rod 31 into the grooved steel 22 may be provided, and the arrangement of the guide pipe 25 may be omitted. . However, when a plurality of guide pipes 25 are arranged at an appropriate interval (see FIG. 4B), it is advantageous in that the mechanical strength of the auxiliary strut 21 can be increased.

  Returning, the fixing nuts 32 and 33 are respectively double nuts, thereby ensuring a fixed fixing state of the auxiliary column 21 using the thread rod 31 to the outer surface of the building A. It is said.

  Incidentally, in the connection means 3 shown in FIG. 5, it is assumed that a plate 34 is provided between the fixing nut 33 screwed from the inside of the building A to the screw rod 31 and the wall A3. Consideration is made so as to easily receive the screwing force of the fixing nut 33 through the plate 34.

  In addition, when a plurality of sub-columns 21 are connected in the vertical direction, the connecting means 3 is connected to each sub-column 21 in order to provide each sub-column 21 on the outer surface of the building A. This is as described above.

  The connecting means 4 shown in FIG. 6 is provided for detachably connecting the auxiliary strut 21 to the outer surface of the building A in the same manner as the connecting means 3 shown in FIG. If this is one embodiment, the connecting means 4 can be said to be another embodiment.

  And even if it exists in this connection means 4, like the connection means 3, the so-called sub-post 21 after use can be separated from the outer surface of the building A as well as after the use. It is possible to change the size of the auxiliary column 21.

  On the other hand, the connection means 4 is used in the case of the relationship with the auxiliary column 21 when the guide pipe 25 provided in the auxiliary column 21 is not used or the guide pipe 25 cannot be used. It is suitable for use.

  That is, in the case of using the connecting means 3 as described above, as shown in FIG. 5, the tip portion (not shown) which is the left end portion of the thread rod 31 in FIG. Protruding state.

  It can be said that the fact that the tip of the thread rod 31 protrudes out of the auxiliary column 21 is not a problem in providing the regulating means 2 on the outer surface of the building A. In consideration of the fact that the working scaffold 5 is provided, it is assumed that when the tip of the thread rod 31 protrudes out of the auxiliary column 21, the tip of the screw rod 31 interferes with the work scaffold 5. From this point of view, it can be said that it is not preferable.

  Therefore, when it is not preferable to use the connecting means 3 that uses the guide pipe 25 provided in the secondary column 21, that is, when it is not used, or from the position where the secondary column 21 is provided on the outer surface of the building A, The connecting means 4 is used when the guide pipe 25 included in the support column 21 cannot be used.

  As described above, the connecting means 4 is provided on the outer surface of the building A with the auxiliary strut 21 sandwiched as shown in FIGS. 6 (A) and 6 (B). The screw rod 42 connected to the holding metal fitting 41 and the fixing nut 43 screwed to the screw rod 42 are provided.

  As shown in FIG. 7 which is an enlarged view, the holding metal fitting 41 opposes the outer surface of the building A of the auxiliary column 21 (see FIG. 6). And a pair of tightening bolts 412 for fixing the hooked band body 411 to the end of the auxiliary column 21 on the building side.

  And as shown to (A)-(C) in FIG. 8, as for the band body 411 with a collar, what is called a main-body part 411a faces the outer surface of the building A of the sub-posts 21 (in FIG. In the central portion in the horizontal direction that is the vertical direction in FIG. 7 and FIGS. 8A and 8B of the surface of the main body 411a that faces the outer surface of the building A. The connection nut 411b for screwing the thread rod 42 to the outer surface of the building A is fixed, and a pair of flange portions 411c facing the side surface of the side end portion of the auxiliary strut 21 are provided. The nuts 411d for screwing the fastening bolts 412 are fixed to the pair of flange portions 411c.

  Incidentally, a bolt insertion hole 411e aiming at the connecting nut 411b is opened in the main body part 411a of the banded band 411 (see FIG. 8C), and the banded part 411c of the banded band 411 includes , A bolt insertion hole (not shown) that is aimed at the nut 411d is opened.

  On the other hand, as shown in FIG. 7, the tightening bolt 412 has a nut 411d that penetrates the thickness of the flange 411c from the outside of the flange 411c in the band 411 and is fixed to the flange 411c. And the front end is brought into pressure contact with the side surface of the end of the auxiliary column 21 on the building side.

  As shown in FIG. 8C, the nut 411d is provided in two so-called upper and lower portions on the flange portion 411c, but if the tightening force of the tightening bolt 412 is sufficient, one nut 411d is provided. Of course, it may be said.

  Therefore, in the holding metal fitting 41, the pair of flange portions 411c of the banded band body 411 are positioned so as to face the building-side end portions of the sub-posts 21, and the positioned pair of flange portions 411c. The fastening bolt 412 is screwed to and attached to the building side end of the sub-post 21 so as to be integrally connected thereto.

  Then, the thread rod 42 (see FIG. 6) is screwed into the holding metal fitting 41 provided at the building side end of the sub strut 21, that is, the connecting nut 411 b included in the hooked band body 411. A fixing nut 43, which will be described later, is screwed into the rear end portion of the screw rod 42 facing the inside of the building A, that is, the rear end portion of the screw rod 42 that passes through the wall A3 that is the housing of the building A and faces the inner side of the building A. Is done.

  In the figure, a recess A5 (see FIG. 6) for fitting the connecting nut 411b is formed on the outer surface of the building A where the auxiliary support column 21 is provided. This is to cope with the case where the auxiliary pillar 21 is in direct contact with the outer surface of the building A. As described above, when there is a gap between the auxiliary pillar 21 and the outer surface of the building A, Of course, instead of fitting the connecting nut 411b in the recess A5, the connecting nut 411b may be positioned in the gap between the auxiliary column 21 and the outer surface of the building A. .

  Therefore, the thread rod 42 is basically formed in the same manner as the thread rod 31 in the connecting means 3 described above, and its length is sufficient to penetrate the wall A3 in the building A, and for fixing. The nut 43 is formed to allow sufficient screwing.

  By the way, from the point shown in FIG. 6, the length of the screw rod 42 in the connecting means 4 is shorter than that of the screw rod 31 in the connecting means 3 described above. This is because it suffices to have a length sufficient to penetrate the wall A3 and allow the fixing nut 43 to be screwed.

  That is, the reason why the thread rod 42 in the connecting means 4 is formed shorter than the thread rod 31 in the connecting means 3 is that when the auxiliary strut 21 is provided on the outer surface of the building A by the connecting means 4, This is to prevent the so-called rear end portion of the screw rod 42 protruding inside the building A from protruding unnecessarily long.

  Therefore, even if the rear end portion of the thread rod 42 in the connecting means 4 protrudes greatly inside the building A, if there is no so-called support, the thread rod 42 in the connecting means 4 is connected to the connecting means 3. It may be replaced with the thread rod 31 in FIG.

  Returning to FIG. 6, the fixing nut 43 is a double nut, and thereby, the fixing nut 43 to the outer surface of the wall A <b> 3 which is the housing of the auxiliary column 21 using the thread rod 42 is used. It is supposed to guarantee a fixed fixing state.

  As shown in the figure, in the connecting means 4, a plate 44 is provided between the fixing nut 43 screwed on the screw rod 42 from the inside of the building A and the wall A 3, and the wall A 3 is the plate 44. Consideration is given so that the screwing force of the fixing nut 43 can be easily received via the screw.

  In addition, when a plurality of sub-posts 21 are connected in the vertical direction, the connecting means 4 has a plurality of sub-posts 21 connected to the outer surface of the building A, that is, to the wall A3. Of course, it may be provided.

  By the way, in the clamping metal fitting 41 constituting the connecting means 4 in the place shown in FIG. 7, the auxiliary metal fitting 413 is associated with the banded band body 411. The auxiliary metal fitting 413 will be described a little.

  That is, in the connection means 4, the banded band body 411 constituting the connection fitting 41 is driven by the tightening force of the tightening bolt 412, in other words, the tip of the tightening bolt 412 and the tightening bolt 412. The bolt 412 is fixedly provided by a frictional force between the front end of the bolt 412 and the building-side end portion of the auxiliary strut 21 in pressure contact.

  From this point of view, the connection state of the connecting metal fitting 41 and the auxiliary column 21 depends on the tightening force of the tightening bolt 412, but the configuration of the auxiliary column 21 is considered as shown in FIG. The flange portion 22a of the grooved shape steel 22 forming the auxiliary strut 21 has no so-called backup member, and therefore the tightening force of the tightening bolt 412 becomes too large. Therefore, there is a concern that the flange portion 22a of the grooved shape steel 22 forming the auxiliary column 21 may be deformed to the groove side, and in the case of actual deformation, the auxiliary column 21 may be bent from the deformed portion. You will be worried.

  Accordingly, in order to prevent the auxiliary strut 21 from being deformed even if the tightening force of the tightening bolt 412 is increased, and even if the tightening force of the tightening bolt 412 is not sufficient, the band with a hook. 411, that is, the auxiliary metal fitting 413 is provided in order to prevent the connecting metal fitting 41 from being separated from the end of the auxiliary column 21 on the building side.

  That is, as shown in FIG. 7 and FIG. 8D, the auxiliary metal fitting 413 is formed so as to have a square U-shaped cross section in which the flange portion 411c of the banded band body 411 faces inside in a plan view. Is done.

  That is, the auxiliary metal fitting 413 includes a main body portion 413a and a pair of flange portions 413b and 413c provided on the main body portion 413a, and the flange portion 411c of the banded body 411 between the pair of flange portions 413b and 413c. And the flange part 22a of the grooved shape steel 22 in the auxiliary strut 21 which opposes this collar part 411c is supposed to face (refer FIG. 7).

  And this auxiliary | assistant metal fitting 413 is a flange part of the grooved shape steel 22 in which one collar part 413b forms the auxiliary column 21 when the collar part 411c and the flange part 22a are made to face between a pair of collar parts 413b and 413c. It functions as a part to back up the flange portion 22a so as to be adjacent to the inner surface of 22a, and a tip (not shown) facing the outer surface of the building A is provided on the inner surface of the grooved steel 22 Are going to face each other.

  On the other hand, the other flange portion 413c of the auxiliary metal fitting 413 is inserted into the bolt insertion hole 314d opened there when the flange portion 411c and the flange portion 22a are faced between the pair of flange portions 413b and 413c. The insertion of the tightening bolt 412 to be screwed into the nut 411d provided on the flange portion 411c of the flanged band body 411 is permitted.

  Therefore, in this auxiliary metal fitting 413, one flange portion 413 b backs up the flange portion 22 a of the grooved steel 22 that forms the auxiliary column 21, and the tightening force of the tightening bolt 412 is increased. Thus, it becomes possible to stabilize the connection state between the connection fitting 41 and the auxiliary support column 21.

  And in this auxiliary metal fitting 413, the other collar part 413c is connected with the collar part 411c of the banded band body 411 via the fastening bolt 412, and the tip of one collar part 413b has a groove. Since the inner surface of the shaped steel 22 is opposed to each other with a gap, if the collar part 411c of the banded band body 411 comes out of the inside of the auxiliary metal fitting 413, the tip of one collar part 413b has a grooved shape. It comes into contact with the inner surface of the steel 22, and the collar part 411c of the banded band body 411 comes out from the inside of the auxiliary metal fitting 413, that is, the connecting metal fitting 41 is separated from the building side end of the auxiliary pillar 21. Will stop.

  FIG. 9 shows an improvement of the holding metal fitting 41 shown in FIG. 7 described above. Specifically, the flange portion 411c of the flanged band body 411 is modified, and the tightening nut 412 is lengthened. The auxiliary metal fitting 413 is modified.

  That is, in the holding metal fitting 41 shown in FIG. 9, the banded band 411 is integrally connected to the auxiliary metal 413 by the bolt and nut 414, whereby the banded band 411 is assisted. By being directly connected to the metal fitting 413, the connection state of the sub-strut 21 of the banded strip 411 to the end portion on the building side is further ensured.

  From this, in the case of the embodiment shown in FIG. 9, compared to the case shown in FIG. 7 described above, the banded body 411 is fixed to the building-side end of the auxiliary column 21. Since a large operating force with respect to the tightening bolt 412, that is, a large tightening force is not required, the setting is made so that one tightening bolt 412 is used. Incidentally, it is needless to say that the tightening bolt 412 may be of a two-upper specification as in the embodiment shown in FIG.

  Returning, the banded body 411 shown in FIG. 9 includes a connecting part 411f formed by bending the hook part 411c along the axial direction of the main body part 411a, as shown in FIGS. The connecting portion 411f is in contact with a long-formed main body portion 413a (see FIG. 10E) of the auxiliary metal fitting 413, and is integrally connected by the bolt nut 414 (see FIG. 9). ).

  Incidentally, the components shown in FIGS. 10A to 10F are the same as those shown in FIG. 8 described above, and the same reference numerals are used in FIG. The description is omitted only by adding.

  By the way, as shown in FIG. 1 and FIG. 2 described above, in the demolition work of the building A, the work scaffold 5 is normally provided outside the building A prior to the dismantling of the building A. In other words, by using this work scaffold 5, it becomes possible to perform various operations for providing the regulating means 2 of the present invention on the outer surface of the building A.

  In addition, by installing the curing screen 5a (see FIG. 2) on the work scaffold 5, it becomes possible to prevent the dust and dust generated during the dismantling work from accidentally falling outside the building A. It becomes possible to form a blindfold considering so-called aesthetics.

  From the above, the working scaffold 5 is provided outside the building A to be dismantled, but it is normal that the working scaffold 5 is connected to the building A so as not to fall apart from the building A. Even in the embodiment, the work scaffold 5 is connected to the building A.

  However, when the work scaffold 5 is connected to the building A, conventionally, that is, in the conventional dismantling method in which the regulating means 2 is not provided, the work scaffold 5 forms the building A by connection as an appropriate means. It is said that it is directly connected to the frame.

  According to this conventional dismantling method, when the building A is dismantled, the connection between the frame to be dismantled, that is, the crushed frame and the work scaffold 5 is removed, so that the work scaffold 5 is easily collapsed. become.

  On the other hand, in the present invention, the work scaffold 5 is connected to the restricting means 2 by the connecting means 6 and 7, as shown in FIG. Not only are they connected together, but also the building scaffolding of the building A is not separated from the outer surface of the building A when the building A is disassembled, that is, crushed, so that the working scaffold 5 does not lose its connection to the building A. Demolition work can be carried out without fear of 5 falling.

  Therefore, the connecting means 6 and 7 in the present invention will be described below. Before that, the working scaffold 5 connected to the regulating means 2 by the connecting means 6 and 7 will be described a little. As is the case with the work scaffolds of the above, it is composed of a frame scaffold or a single pipe scaffold, and in any case, it is often launched from the ground, for example, so as to surround the building A from the outside. .

  Incidentally, it is not essential that the work scaffold 5 is connected to the outer surface of the building A from the viewpoint of the present invention. Therefore, the work scaffold 5 is connected to the building A while being connected to the regulating means 2, or Of course, even if it is connected to the building A without being connected to the restricting means 2, the implementation of the present invention is not hindered.

  Returning, in the illustrated embodiment, the work scaffold 5 is composed of a frame scaffold, which is not shown in detail, but, for example, as shown in FIG. , And a plurality of building frames 51 that are continuous along the upper side, and a scaffolding plate (not shown) and a brace (not shown) that connect the plurality of building frames 51 in the lateral direction.

  The building frame 1 includes a pair of vertical struts 51a and a horizontal member 51b that connects the upper ends of the pair of vertical struts 51a, and the pair of vertical struts 51a allows connection of the upper vertical struts 51a. The horizontal member 51b allows the scaffolding board where the worker enters, and the breath prevents the building frame 51 on which the scaffolding board is placed from falling in the alignment direction.

  When the building frame 51 is in a normal state (see FIG. 2), the pair of vertical columns 51 a connected by the horizontal member 51 b are orthogonal to the outer surface of the building A. Of course, the plurality of building frames 51 may not be aligned linearly but may be aligned in a so-called wavy manner.

  In the working scaffold 5, whether the plurality of building frames 51 are aligned linearly or wavyly aligned, the working scaffold 5 is connected to the connecting means 6, 7 in the present invention. Is connected to building A.

  Incidentally, the connecting means 6 and 7 described below are illustrated as examples, and it is a matter of course that the use of connecting means formed in an arbitrary structure (not shown) is not excluded.

  FIG. 11 shows one embodiment of the connecting means 6, and a clamping bracket 61 that clamps the scaffold-side end portion that is the left end portion in FIG. 11 in the auxiliary strut 21 and the clamping bracket 61 is connected. In addition, a pair of connecting bodies 62 connected to the vertical struts 51a in the frame 51 forming the work scaffold 5 are provided.

  As shown in FIG. 11 (B), the holding metal fitting 61 is configured in the same manner as the holding metal fitting 41 shown in FIGS. 6 and 7 described above. Therefore, detailed description of the holding metal fitting 61 is omitted. To do.

  Incidentally, the connecting means 7 according to another embodiment shown in FIG. 12 also includes a holding metal fitting 71 for holding the scaffold side end portion which is the left end portion in FIG. The sandwiching metal 71 is also configured in the same manner as the sandwiching metal 41 shown in FIGS. 6 and 7 described above, and therefore, detailed description of the sandwiching metal 71 is also omitted.

  Returning to the connecting means 6, the assembled connecting body 62 includes a first clamp 62 a that is connected to the holding fitting 61 by screwing or the like, a first single tube 62 b that is held by the first clamp 61 a, A second clamp 62c for sandwiching the first single tube 62b; a second single tube 62d for sandwiching the second clamp 62c; and an orthogonal clamp 62e for sandwiching the second single tube 62d. 62e clamps the vertical column 51a that forms the building frame 51.

  Therefore, in this connecting means 6, the holding metal fitting 61 that holds the end of the side of the auxiliary column 21 is connected to the vertical column 51 a of the building frame 51 that constitutes the work platform 5 by the assembly coupling body 62. Thus, the work scaffold 5 is connected to the auxiliary column 21.

  Incidentally, in the embodiment shown in FIG. 11, the axis passing through the center of the connecting nut 611 b provided on the holding metal fitting 61 is horizontal to the axis of the vertical column 51 a in the building frame 51 constituting the work scaffold 5. This is suitable for use when connecting the holding metal fitting 61 and the vertical support column 51a when they cannot be orthogonal to each other.

  On the other hand, in the connecting means 7 of the embodiment shown in FIG. 12, the axis passing through the center of the connecting nut 711 b provided on the holding metal fitting 71 is an axis of the vertical column 51 a in the building frame 51 constituting the work scaffold 5. This is suitable for use in the case of being orthogonal to the axis from the horizontal direction. As a result, the number of constituent members can be reduced as compared with the connecting means 6 shown in FIG. 11, which is advantageous in terms of cost.

  Incidentally, in the connecting means 7 shown in FIG. 12, the holding fitting 71, the rod-like connecting body 72 connected to the connecting nut 711 b provided on the holding fitting 71, and the rod-like connecting body 72 are connected to the work scaffold 5. And a clamp 73 connected to the vertical column 51a in the building frame 51.

  In addition, in the connecting means 7, the rod-like connecting body 72 may be able to cope with the case where the dimension between the auxiliary support column 21 and the building frame 51 is varied by extending and contracting in the axial direction. Of course.

  FIGS. 13 to 15 show a connecting means 10 of still another embodiment. In FIGS. 13, 14 and 15A, the connecting means 10 is shown together with the auxiliary column 21, and FIG. B) shows the sub-post 21 with the connecting means 10 omitted.

  First, the difference between the connecting means 10 and the connecting means 3 (see FIG. 5) and the connecting means 4 (see FIG. 6) will be described. The connecting means 3 and 4 are connected to the outer surface of the building A. The auxiliary strut 21 is connected to the outer surface of the building A from the state where the auxiliary strut 21 is in contact.

  On the other hand, the connecting means 10 of this other embodiment connects the connecting column 10 to the connecting means 10 from the state where the connecting means 10 is connected to the building A first, and so on. The support column 21 is connected to the outer surface of the building A by the connecting means 10.

  That is, when the floor heights of the building A to be demolished tend to be unified, it is easy to specify the positions where the connecting means 3 and 4 are provided, and therefore, the sub-preparation that is the so-called setup is prepared. It is possible to easily carry out the operation of connecting the support column 21 to the building A and then connecting it to the building A by the connecting means 3 and 4.

  On the other hand, when the floor height of the building A to be demolished tends to vary, it is not easy to specify the position where the connecting means 3 and 4 are provided. It can be said that the operation of connecting the auxiliary column 21 to the connecting means 10 connected to the building A is advantageous in facilitating the entire operation when the auxiliary column 21 is provided on the outer surface of the building A.

  On the other hand, in the case of using this connecting means 10, it becomes possible to provide the connecting means 10 not on the inside of the building A but on the outside of the building A, that is, on the wall A3 which is the frame from the work scaffold 5 side, and its meaning Then, there exists an advantage which can respond to the case where there is no room for a worker to enter inside the building A, for example, there is no floor A4.

  The connecting means 10 will be described based on the premise as described above. The connecting means 10 is formed in a bracket structure that is detachably provided in the building A and that removably connects the auxiliary column 21 after the eaves.

  That is, as shown in FIG. 13 to FIG. 15, the connecting means 10 includes an arm portion 101 that is a main body portion disposed in the lateral direction in FIG. 13 and a right end portion of the arm portion 101 in FIG. 13. The locking part 102 provided in the one end part which consists of, and the fixing | fixed part 103 provided in the other end part which becomes the left end part in FIG. 13 of the arm part 101 are provided.

  As shown in the figure, the arm portion 101 has a hole through which the connecting means 10 opened in the wall A3, which is a housing in the building A, that is, the outside of the building A on the left side in FIG. Is inserted into the building A on the right side in FIG. 13, and the other end is formed to leave the outside of the building A. In particular, the other end is It is assumed that the structure is provided with a length that allows the auxiliary column 21 to be connected to the fixed portion 103 and protrudes outside the building A.

  As shown in FIG. 14, the locking portion 102 is provided at one end of the arm portion 101, and when it is present inside the building A, it is in a position to hang down and forms an insertion hole A <b> 5 that comes into contact with the heel. It is assumed that it faces the wall A3 (see FIG. 14B).

  As shown in FIG. 14, the fixing portion 103 is provided at the other end portion of the arm portion 101, and one end portion of the arm portion 101, that is, when the locking portion 102 is present inside the building A. The wall A3 that is left outside the building A and hangs down so as to face the locking portion 102 is sandwiched between the locking portion 102 and the wall A3 that forms the insertion hole A5. .

  And this fixing | fixed part 103 clamps wall A3 positioned between the latching | locking parts 102, ie, wall A3 which forms insertion hole A5, or the fixing bolt which is a fixing means which cancels | releases this clamping 104 and a connecting mechanism (not shown) that enables the sub-supporting column 21 to be detachably connected to the fixing portion 103.

  The fixing bolt 104 in the fixing portion 103 moves along the axial direction of the arm portion 101 when rotating, that is, advances and retreats, and a wall A3 that forms an insertion hole A5 with the locking portion 102 when moving forward. Hold it and release it when retreating.

  In the illustrated embodiment, the fixing bolts 104 are provided in two upper and lower stages along the axial direction of the auxiliary strut 21 in order to allow the predetermined functions to be performed. As long as it is exerted, it may be one step, that is, one.

  Next, the coupling mechanism provided between the fixing portion 103 and the auxiliary column 21 may be arbitrarily configured as long as it allows the auxiliary column 21 to be detachably connected to the fixing unit 103. In the illustrated embodiment, as shown in FIG. 15, the fixed portion 103 includes a headed bolt 105 that is a hook member, and the sub-column 21 has a dharma hole 21 a that allows the head bolt 105 that is a hook member to be caught. It is assumed that when the headed bolt 105 of the fixing part 103 is engaged with the dharma hole 21a of the auxiliary column 21, the connection of the auxiliary column 21 to the fixing part 103 is realized.

  Therefore, in the connection mechanism including the headed bolt 105 and the dharma hole 21a, the auxiliary strut 21 is positioned along the fixed portion 103, and the auxiliary strut 21 is moved up and down, for example. When the head bolt 105 is engaged with the dharma hole 21 a, the auxiliary column 21 can be connected to the fixing portion 103, that is, the connecting means 10.

  The dharma holes 21a may be provided on both side surfaces of the auxiliary column 21. At this time, in the illustrated embodiment, they are formed so as to be turned upside down. It may be formed in a direction, or may be formed in two stages that are upside down on one side.

  In view of the above, in the coupling mechanism, the hooking member is made of an L-shaped shaft (not shown) instead of the headed bolt 105, and allows the hooking member to be hooked. Although not shown in the figure, the portion may be formed of a fine hole extending in the vertical direction instead of the Dalma hole 21a.

  Incidentally, the above-described dharma hole 21a and the pore are formed in the belt plate 26 of the auxiliary strut 21 in the illustrated embodiment. 13 (A)), the arrangement of the lattice 23 at the portion where the band plate 26 is provided in the auxiliary strut 21 is omitted.

  By the way, in embodiment shown in figure, the connection means 10 rotates with the said insertion hole A5 centering on the axis line of the arm part 101 extended in FIG. It is set to enable inversion.

  This setting is because not only when the connecting means 10 is inserted into the insertion hole A5, but also the operability at the time of extraction from the insertion hole A5 is improved. That is, with regard to making the connecting means 10 formed in the bracket structure freely removable into the insertion hole A5, the insertion / removal operation can be easily performed if the insertion hole A5 is formed infinitely large.

  However, it is uneconomical to form the insertion hole A5 for inserting / removing the connecting means 10 larger than necessary, and it is normal to make it the minimum size. Therefore, in the illustrated embodiment, the insertion hole A5 is formed to the minimum necessary size, while the connection means 10 is devised. Specifically, the connection means 10 is turned upside down. This facilitates the insertion / removal of the connecting means 10, especially the extraction.

  That is, in this connecting means 10, the locking portion 102 provided at one end portion of the arm portion 101 is pivotally attached to the arm portion 101 by the shaft 102 a as shown in FIG. 14, with respect to the axial direction of the arm portion 101. As shown by the solid line in FIG. 13, the wall A <b> 3 that forms the insertion hole A <b> 5 between the fixing portion 103 is sandwiched when the locking portion 102 is in a position to hang down as shown by the solid line in FIG. 13. Suppose you can.

  On the other hand, although not shown in the figure, the arm portion 101 is reversed and the locking portion 102 is put into an upward state, so that the arm portion 101 and the locking portion 102 in this state are lowered in overall height. It is supposed that it can easily pass through the insertion hole A5.

  In addition, since the locking portion 102 is connected to the arm portion 101 so as to be raised and lowered, although not shown, one end portion of the arm portion 101, that is, the locking portion 102 is inserted through the insertion hole A5 formed in the wall A3. Sometimes, the engaging portion 102 is folded with respect to the arm portion 101, and the opening area of the insertion hole A5 can be set small, and the insertion of the insertion hole A5 is facilitated.

  Note that when the locking portion 102 is in a posture to hang down at one end portion of the arm portion 101 and the wall A3 is sandwiched between the locking portion 102 and the fixing portion 103, in order to ensure this clamping posture, as shown in FIGS. As described above, the arm portion 101 includes a support portion 101a at one end portion, and the back surface of the locking portion 102 is in contact with the support portion 101b.

  On the other hand, in the illustrated embodiment, the fixed portion 103 is held by a slider 106 that is movably interposed in the arm portion 101, and the above-mentioned headed portion that constitutes the coupling mechanism by the movement of the slider 106. The projecting position of the bolt 105 with respect to the arm portion 101 can be changed.

  At this time, the slider 106 is formed of a square pipe having a cross section similar to that of the arm portion 101, and the fixing of the slider 106 to the arm portion 101 is performed by a hole (notation) passing through the slider 106 and the arm portion 101 in the illustrated embodiment. It is embodied by inserting a shaft member 106a (see FIG. 14A) such as a bolt into a bolt (not shown). Of course, any other measures may be selected as a fixing measure. is there.

  Further, the connecting means 10 is in the illustrated embodiment, and as shown in FIG. 14B, the slider 106 constituting the fixing portion 103 is detachably attachable to the guide frame 107 through which the auxiliary column 21 is inserted. It is supposed to be prepared. In FIG. 14A, the guide frame 107 is not shown.

  When the slider 106 constituting the fixing portion 103 includes the guide frame 107 through which the auxiliary column 21 is inserted, the auxiliary column 21 is connected to the connecting means 10 provided on the outer surface of the building A. By inserting the support post 21 into the guide frame 107, it becomes possible to make the auxiliary support post 21 close to the fixing portion 103 without being so decentered. The connection with the unit 103 can be quickly implemented.

  Incidentally, the guide frame 107 is inserted into a hole 106b formed in the slider 106 with a base portion (not shown) and a hole (not shown) formed in the arm portion 101 aiming at the slider frame 106. It is supposed to be separable.

  As described above, in the regulating means 2, it is assumed that a plurality of sub-columns 21 formed in a short length are connected to each other in the vertical direction and provided on the outer surface of the building A. The restricting means 2 only needs to be provided on the outer surface of the building A. Therefore, the sub-posts 21 may be provided independently on the outer surface of each floor of the building A without being connected in the vertical direction. Of course, the operational effects of providing the regulating means 2 in that case are not different.

  In addition, as described above, for example, in the clamping bracket 41 that clamps the secondary strut 21 in the connecting means 4, the fastening bolt 412 has a flange of the grooved steel 22 that forms the sub strut 21 at the tip. Although it is in contact with the portion 22a, instead of this, although not shown, the tip of the fastening bolt 412 may be inserted through the flange insertion portion 22a of the grooved steel 22 into the bolt insertion hole. Well, in this case, it is advantageous in that the separation of the banded band 411 from the auxiliary column 21 can be reliably prevented. Incidentally, the same applies to the holding fitting 41 shown in FIG. 9, the holding fitting 61 shown in FIG. 11, and the holding fitting 71 shown in FIG.
